As disclosed in Patent Document 1 below, conventionally, there is an elevator having an automatic diagnosis temporary restoration operation function. The automatic diagnosis temporary recovery operation function mechanically diagnoses the risk of damage to elevator equipment in order to ensure the convenience of movement within the building at an early stage until the recovery by a specialist engineer (maintenance staff). , A function to temporarily restore.

Further, conventionally, the condition for performing the automatic diagnosis temporary restoration operation is that the earthquake detector (particularly, the S wave detector) does not detect a shake (acceleration) of a preset value or more. There is. This set value considers only the strength design of the building (referred to as "[diagnosis] setting") or the strength design of the building and the amplitude expansion of ropes ("[high] setting". It is set to the seismic detector as (generally referred to as "diagnosis" setting or less).

Further, in recent years, the development of a technology in which IoT (Internet of Things) is applied to an elevator has been advanced.

Japanese Patent Laid-Open No. 2008-266006 (published on November 6, 2008)

In the conventional elevator, if the above conditions cannot be satisfied, the operation cannot be restarted without the inspection of a professional engineer. In other words, if the above conditions cannot be satisfied, the elevator will remain stopped until a professional engineer inspects it. Therefore, if a situation occurs in which a large number of elevators cannot satisfy the above conditions (for example, when a large earthquake occurs), if a specialist engineer inspects all of these elevators and restarts the operation, As the restart of the operation is delayed, the burden on the professional engineer increases.

In view of the above problems, an aspect of the present invention is to provide an elevator operation control system capable of quickly restarting the operation of an elevator that has been stopped due to the occurrence of sway and reducing the burden on a professional engineer. To do.

In order to solve the above problems, an information processing apparatus according to an aspect of the present invention relates to a target elevator that has been shaken and stopped, and a first acquisition unit that acquires shake data indicating the magnitude of the shake, and When the reference elevator, which is the same as or different from the target elevator, is shaken in the past and stopped, shake data indicating the magnitude of the shake and inspection result data indicating the subsequent inspection result for the reference elevator are at least associated with each other. Storage unit for storing as reference data, and an operation permitting unit for determining whether or not to permit execution of the automatic diagnosis provisional recovery operation for the target elevator based on the acquired shake data and the reference data. Prepare

According to the above configuration, for the target elevator that has been shaken and stopped, the shake data indicating the magnitude of the shake that the reference elevator has received in the past, and the inspection result indicating the inspection result of the reference elevator after the shake. Based on the data, it is determined whether or not the execution of the automatic diagnosis temporary restoration operation is permitted. As a result, even if the target elevator stops due to a shake of a set value or more set for prohibiting execution of the automatic diagnosis temporary recovery operation, the automatic diagnosis temporary recovery operation may be able to be performed. Therefore, the temporary restoration of the elevator, that is, the restart of the operation can be quickly performed. Further, since the operation can be restarted without the inspection of the professional engineer, the burden on the professional engineer can be reduced.

Further, in the information processing device according to an aspect of the present invention, a second acquisition unit that acquires event data indicating an event other than the magnitude of the shake that may affect the degree of damage to the target elevator due to the occurrence of the shake. Further comprising, the reference data further includes the event data when the reference elevator has been shaken in the past and stopped, the operation permitting unit, in the event data acquired by the second acquisition unit. Based on the above, it may be determined whether or not to permit execution of the automatic diagnosis temporary restoration operation for the target elevator.

According to the above configuration, in addition to the shaking data and the inspection result data, the automatic diagnosis temporary restoration operation is executed based on the event data indicating the events other than the magnitude of the shaking that may affect the damage degree of the elevator. Determine whether to allow. This makes it possible to more accurately determine whether or not to permit execution of the automatic diagnosis provisional recovery operation.

Further, in the information processing device according to an aspect of the present invention, the second acquisition unit, as the event data, data indicating the position of the car of the target elevator when the target elevator is shaken and stopped. And the reference data may further include, as the event data, data indicating the car position when the reference elevator was shaken in the past and stopped.

According to the above configuration, the event data includes data indicating the position of the car when the elevator was shaken and stopped. That is, whether or not the information processing device allows the execution of the automatic diagnosis temporary recovery operation based on the data indicating the position of the car when the elevator stops due to the shaking, in addition to the shaking data and the inspection result data. To judge. This makes it possible to more accurately determine whether or not to permit execution of the automatic diagnosis provisional recovery operation.

For example, the information processing device may identify whether the position of the car is within the resonance range or within the non-resonance range in order to determine whether to allow execution of the automatic diagnosis temporary recovery operation. Good. The resonance range is a range in which the rope easily resonates when shaking occurs when the position of the car is within the range. The non-resonance range is a range in which the rope is hard to resonate even if swing occurs when the position of the car is within the range. The resonance range and the non-resonance range are predetermined based on the natural period of the building in which the elevator is installed and the specifications of the elevator. When the position of the car is within the non-resonance range, the rope of the elevator becomes difficult to sway, so there is a possibility that the rope will be caught by each member in the hoistway or may be damaged by contacting each member. It is lower than when the position is within the resonance range. In other words, when the position of the car is in the non-resonance range, there is a possibility that the automatic diagnosis temporary restoration operation can be executed. Therefore, by specifying whether the position of the car is within the resonance range or the non-resonance range, the specification result is used as one condition for determining whether or not to allow execution of the automatic diagnosis provisional recovery operation. be able to.

Further, in the information processing device according to the aspect of the present invention, the second acquisition unit indicates, as the event data, a moving state of the car of the target elevator when the target elevator is shaken and stopped. Data may be acquired, and the reference data may further include, as the event data, data indicating a moving state of the car when the reference elevator has been shaken in the past and stopped.

According to the above configuration, the event data includes data indicating the moving state of the car when the elevator is shaken and stopped. That is, whether the information processing apparatus allows the execution of the automatic diagnosis provisional recovery operation based on the shaking data and the inspection result data as well as the data indicating the moving state of the car when the elevator is shaken and stopped. To determine. This makes it possible to more accurately determine whether or not to permit execution of the automatic diagnosis provisional recovery operation.

For example, the information processing device may specify whether or not the car was moving when the shaking occurred to determine whether or not to allow execution of the automatic diagnosis provisional recovery operation. If the car is not moving, it is unlikely that the car will disengage from the rail, so-called railing. In other words, when the car is not moving, there is a possibility that the automatic diagnosis temporary restoration operation can be executed. Therefore, by specifying whether or not the car has moved, this specification result can be used as one condition for determining whether or not to permit execution of the automatic diagnosis provisional recovery operation.

In the information processing device according to an aspect of the present invention, the second acquisition unit may use, as the event data, a direction of the target elevator when the target elevator is shaken and stopped. May be acquired, and the reference data may further include, as the event data, data indicating a direction of the shaking when the reference elevator has been shaken in the past and stopped.

According to the above configuration, the event data includes data indicating the direction of the shaking with respect to the direction of the elevator when the elevator is shaken and stopped. In other words, the information processing device permits the execution of the automatic diagnosis temporary recovery operation based on the shake data and the inspection result data, and also based on the data indicating the direction of the shake with respect to the direction of the elevator when the elevator stops due to the shake. It is determined whether to do. This makes it possible to more accurately determine whether or not to permit execution of the automatic diagnosis provisional recovery operation.

For example, the information processing apparatus determines whether or not the swing direction is a direction in which the rope of the elevator does not swing in the direction of the guide rail on the car side in order to determine whether or not to allow execution of the automatic diagnosis provisional recovery operation. May be specified. In a typical elevator, various switches are arranged on a car-side guide rail via a bracket. Here, if the rope does not swing in the direction of the guide rail on the car side, it is unlikely that the rope comes into contact with these switches and breaks down. In other words, if the rope does not swing in the direction of the car-side guide rail, there is a possibility that the automatic diagnostic provisional recovery operation can be executed. Therefore, by specifying whether or not the rope is in the direction that does not sway in the direction of the guide rail on the car side, this specification result is used as one condition for determining whether or not to allow execution of the automatic diagnosis provisional recovery operation. Can be used.

Further, in the information processing device according to an aspect of the present invention, further includes a specifying unit that specifies reference data indicating a shake similar to the shake received by the target elevator among the reference data, and the operation allowance unit is The reference data specified by the specifying unit may indicate that the inspection result indicates that the operation can be restarted, as a necessary condition for permitting execution of the automatic diagnosis provisional recovery operation.

According to the above configuration, the reference data indicating the sway similar to the sway received by the target elevator shows the inspection result indicating that the reference elevator has no abnormality, which allows the execution of the automatic diagnosis temporary restoration operation. It is necessary to do. In other words, in the reference data indicating a shake similar to the shake received by the target elevator, if the inspection result indicates that the reference elevator is abnormal, the information processing device does not allow execution of the automatic diagnostic operation. .. This makes it possible to more accurately determine whether or not to permit execution of the automatic diagnosis provisional recovery operation.

Further, in the information processing device according to an aspect of the present invention, based on the sway data and the event data, further includes a calculation unit that calculates a damage degree of the target elevator, the storage unit, in the reference elevator The threshold value calculated based on the shake data and the event data included in the reference data showing the inspection result indicating that there is no abnormality is further stored, and the operation allowance unit calculates by the calculation unit. The determined damage level may be equal to or less than the threshold value as a necessary condition for permitting execution of the automatic diagnosis provisional recovery operation.

According to the above configuration, the damage degree calculated based on the shake data and the event data of the target elevator is equal to or less than the threshold calculated based on the reference data showing the inspection result indicating that there is no abnormality. However, it is necessary to allow the execution of the automatic diagnosis temporary restoration operation. This makes it possible to determine whether or not to permit execution of the automatic diagnosis temporary restoration operation based on all reference data including the inspection result indicating that the elevator 200 has no abnormality. Therefore, it is possible to more accurately determine whether or not to permit execution of the automatic diagnosis provisional recovery operation.

Further, in the information processing device according to an aspect of the present invention, the operation permitting unit exhibits a sway of a magnitude greater than a sway indicated by the sway data acquired by the first acquisition unit, and the reference elevator has an abnormality. The existence of reference data indicating the inspection result indicating that there is no such condition may be a necessary condition for permitting execution of the automatic diagnosis provisional recovery operation.

According to the above configuration, the automatic diagnosis temporary recovery operation indicates that there is reference data indicating a check result indicating that there is no abnormality in the elevator, indicating a shake that is equal to or greater than the shake indicated by the shake data of the target elevator. Required to allow the execution of. If there is reference data indicating that there is no abnormality as a result of the inspection even though the subject elevator has been shaken more than the target elevator, the target elevator may have no abnormality. Therefore, by determining whether or not the execution of the automatic diagnosis provisional recovery operation is permitted under such conditions, it is possible to accurately determine whether or not the execution of the automatic diagnosis provisional recovery operation is permitted.

According to one aspect of the present invention, it is possible to quickly restart an elevator after an earthquake and reduce the burden on a professional engineer.

[Embodiment 1]
Hereinafter, one embodiment of the present invention will be described in detail.

(Outline of elevator 100)
FIG. 2 is a schematic diagram showing a part of the configuration of the elevator 100. The schematic configuration of the elevator 100 is not limited to the illustrated example.

The illustrated elevator 100 is an elevator including a hoistway 21 and a machine room 22. The position of the machine room 22 is not limited to above the hoistway 21. Further, the elevator 100 may not have the machine room 22.

As shown, the car 23 of the elevator 100 is connected to one end of a rope 24. A counterweight 25 is connected to the other end of the rope 24. The hoisting machine 26 installed in the machine room 22 hoists the rope 24, so that the car 23 moves up and down in the hoistway 21.

In the machine room 22, a control panel 1 (information processing device) that controls each part of the elevator 100 is installed. The control panel 1 moves the car 23 to the floor designated by the user and stops the car 23 at the floor according to the control signal obtained from various buttons (for example, a landing button) provided on the elevator 100. 23, the opening and closing of the doors provided in the hall, the display change of the position indicator provided in the hall, and the like are controlled.

The control panel 1 is also configured to be able to communicate with an external device via a predetermined communication network 6 (for example, the Internet). For example, the control panel 1 may communicate with the information processing device 5 via the communication network 6 as illustrated. The information processing device 5 will be described later.

In addition, the control panel 1 controls the operation of the elevator 100 after the shaking occurs. As shown in the figure, the earthquake detector 2 is installed in the machine room 22. The earthquake detector 2 operates when the acceleration of shaking due to an earthquake is equal to or greater than a preset value (hereinafter, referred to as a “set value”), and outputs an operation signal to the control panel 1. In the illustrated example, only one earthquake detector 2 is described in consideration of the visibility of the drawing, but typically, a plurality of earthquake detectors 2 having different set values are installed. In the present embodiment, an example will be described in which three seismic detectors 2, a P wave detector, a low setting detector, and a high setting detector, are installed in the machine room 22. The P wave detector detects the P wave of an earthquake. The low setting sensor and the high setting sensor are S wave sensors that detect the S wave of an earthquake.

A set value of 2.5 Gal or more and 10 Gal or less is set in the P wave sensor. The S wave sensor is typically set to one of three set values called "extra low" setting, "low" setting, and "high" setting. Of these three set values, the [extra low] setting is the smallest value and the [high] setting is the largest value. The low setting sensor is the seismic sensor 2 having the [low] setting among the above three set values, and the high setting sensor is the seismic sensor 2 having the [high] setting. Specific values of the [low] setting and the [high] setting may be determined according to the height of the building in which the elevator 100 is installed from the ground. For example, in a building with a height of 60 m or less, when the seismic detector 2 is installed above the hoistway 21 as shown, the [low] setting is 200 Gal and the [high] setting is 300 Gal.

In addition, in the case of a high-rise building, specifically, a building with a height of more than 60 m and less than 120 m, the rope 24 sways at the top of the building due to an earthquake accompanied by surface waves that cannot be detected by the P wave detector It can grow. In such a case, in addition to these three seismic detectors 2, an S wave detector of [extra low] setting may be installed. A specific value of the [extra low] setting is, for example, 40 Gal in the case of a building having a height higher than 60 m and lower than 90 m.

Further, instead of the high setting sensor, an S wave sensor of [diagnosis] setting may be installed. The [diagnosis] setting is a setting value that takes into consideration only the strength design of the building, whereas the [high] setting is a setting value that takes into account the strength design of the building and the amplitude increase of the rope 24. Therefore, the specific value of the [diagnosis] setting is a value equal to or higher than the [high] setting.

Further, the earthquake detector 2 may be installed in a place other than the machine room 22. For example, it may be installed in the lower part of the hoistway 21, or may be installed in a place different from the elevator 100 in the building. The P-wave detector is installed in the lower part of the hoistway 21 in principle. In addition, when the low setting sensor and the high setting sensor are installed in the lower part of the hoistway 21, the set value is made smaller than in the case where the low setting sensor and the high setting sensor are installed in the upper part of the hoistway 21. For example, in a building whose height from the ground is 60 m or less, when the low setting sensor and the high setting sensor are installed in the lower part of the hoistway 21, the set values are 80 Gal and 120 Gal, respectively.

Further, when a plurality of elevators are installed in the building, the earthquake detector 2 may be installed for each elevator or may be shared.

In addition, in this indication, the cause of the shaking which occurs in the elevator 100 is not intended to be limited to an earthquake. The cause of the shaking generated in the elevator 100 may be, for example, a strong wind.

The control panel 1 performs processing according to the type of the earthquake detector 2 that outputs the operation signal. Specifically, when the operation signal is acquired only from the P wave sensor, the control panel 1 stops the operation of the elevator 100 for a predetermined time and then restarts it. Further, when the operation signals are obtained from the P wave sensor and the low setting sensor, the control panel 1 performs the automatic diagnostic operation for the temporary restoration if the automatic diagnostic operation is possible. Further, when the operation signals are acquired from all the seismic detectors 2, the control panel 1 basically does not restart the operation of the elevator 100 until the inspection by the specialist is performed. In other words, the automatic diagnosis operation and the temporary recovery operation that is executed when it is determined that there is no abnormality in the automatic diagnosis operation (hereinafter, these two operations are collectively referred to as the automatic diagnosis temporary recovery operation) are performed. The condition for this is that the high setting sensor (or the seismic sensor 2 with the [diagnosis] setting) does not detect a shake (acceleration) of a preset value or more. That is, the set value set in the high setting sensor (or the earthquake sensor set to [diagnosis]) is the set value set to prohibit the execution of the automatic diagnosis temporary recovery operation.

Note that the control panel 1 may exceptionally execute the automatic diagnosis temporary restoration operation even if the operation signals are acquired from all the earthquake detectors 2. This point will be described later.

Further, as illustrated, the car 23 according to the present embodiment is provided with an acceleration sensor 3A. The acceleration sensor 3A detects the acceleration generated in the car 23 every predetermined time (for example, every 0.5 seconds). An acceleration sensor 3B is installed near the earthquake detector 2 in the machine room 22. The acceleration sensor 3B is provided for the control panel 1 to specify the magnitude and direction of the shake when the elevator 100 shakes due to an earthquake or the like, by using the acceleration detected by the acceleration sensor 3B. There is. Similarly to the acceleration sensor 3A, the acceleration sensor 3B also detects acceleration every predetermined time (for example, every 0.5 seconds). In the following description, if the acceleration sensors 3A and 3B are not distinguished, they may be collectively referred to as the acceleration sensor 3. Further, the acceleration sensor 3 may be an existing one.

The installation position of the acceleration sensor 3A may be any position as long as it can detect the acceleration generated in the car 23, and may be installed at a position different from the example shown in the figure, for example, on the lower outer side or side surface of the car 23 It may be installed inside 23. Further, the installation position of the acceleration sensor 3B is preferably installed in the vicinity of the seismic sensor 2 in order to suppress a deviation from the detection result of the seismic sensor 2. In other words, when the seismic sensor 2 is installed at a position different from the machine room 22, the acceleration sensor 3B is also different from the machine room 22 (that is, the position where the seismic sensor 2 is installed). (Near the).

(Structure of main parts of control panel 1)
FIG. 1 is a block diagram showing an example of the main configuration of the control panel 1. As illustrated, the control panel 1 includes a control unit 10, a communication unit 11, and a storage unit 12. The control unit 10 centrally controls each unit of the control panel 1. The communication unit 11 is connected to a device outside the control panel 1 so as to be able to communicate by wire or wirelessly, and acquires data from the device. The storage unit 12 stores various data used by the control panel 1. The storage unit 12 stores at least layout information 121, car movement information 122, and a reference data table 123.

The layout information 121 is information regarding the layout of the elevator 100, including the arrangement and dimensions of each member of the elevator 100. Specifically, the layout information 121 is at least the height of each floor of the elevator 100 from the ground, and information indicating which direction the elevator 100 is facing (hereinafter referred to as "elevator direction information"). including. The elevator azimuth information may be, for example, information indicating the azimuth of the surface on which the door of the elevator 100 is installed.

The car movement information 122 is information indicating a temporal change in the position of the car 23. FIG. 3 is a diagram showing a specific example of the car movement information 122. The car movement information 122 may indicate the position of the car 23 on the floor as shown in the figure, or may indicate the height from the ground. The details of the car movement information 122 will be described later.

The reference data table 123 is a table for storing reference data. The "reference data" means automatic diagnosis provisional in an elevator (hereinafter referred to as "target elevator") that has been stopped due to the shaking caused by the operation of the high setting sensor (or the seismic sensor 2 of [Diagnosis] setting). It is data to be referred to in order to determine whether or not to execute the recovery operation. The reference data is the magnitude of the shake when the reference elevator, which is the same as or different from the target elevator, has been shaken in the past by a magnitude greater than the set value set to prohibit the execution of the automatic diagnosis temporary restoration operation. And the inspection result data indicating the result of the subsequent inspection of the reference elevator are at least associated with each other.

In the present embodiment, the reference elevator and the target elevator are the same elevator, that is, the elevator 100. That is, in the control panel 1 according to the present embodiment, in the elevator 100, when the high setting sensor (or the seismic detector 2 with the [diagnosis] setting) operates, a shake occurs in the elevator 100 in the past. It is determined whether or not to execute the automatic diagnosis temporary restoration operation by referring to the data (reference data) related to.

In addition, the reference data of the present embodiment further includes event data indicating an event other than the magnitude of the shaking, which may affect the degree of damage to the elevator 100 due to the occurrence of the shaking having a magnitude equal to or larger than the set value. There is. Further, the reference data of the present embodiment includes information indicating whether or not the elevator 100 has executed the automatic diagnosis operation (hereinafter, referred to as “diagnosis operation availability”). The details of whether or not the diagnostic operation is possible will be described later. That is, the reference data of this embodiment is data in which shake data, inspection result data, event data, and whether or not diagnostic operation is possible are associated with each other. Typical examples of the above-mentioned event are (1) when the sway occurs, the elevator 100 sways (or does not sway) in a predetermined direction, and (2) when the sway occurs, the car 23 is (or is not) in a predetermined position. ) And (3) the car 23 was moving (or was stopped) when the shaking occurred. The details of the reference data table 123 will be described later.

As shown in FIG. 1, the control unit 10 includes a data acquisition unit 101, a similar situation specifying unit 102, an operation control unit 103, and an associating unit 104.

The data acquisition unit 101 acquires the shaking data and the event data. Specifically, when the data acquisition unit 101 acquires an operation signal from the earthquake detector 2 via the communication unit 11, the data acquisition unit 101 outputs the operation signal to the operation control unit 103 and outputs the operation signal from any one of the earthquake detectors 2. Determine if it is a motion signal. When the motion signals are from all the seismic detectors 2, the data acquisition unit 101 acquires the shaking data and the event data.

As shown in FIG. 1, the data acquisition unit 101 includes an acceleration acquisition unit 111 (first acquisition unit, second acquisition unit), a car position acquisition unit 112 (second acquisition unit), and a movement state acquisition unit 113 (second acquisition unit). Acquisition part) is included.

The acceleration acquisition unit 111 acquires the magnitude of the shaking and the direction of the shaking with respect to the direction of the elevator 100, based on the acceleration of the shaking generated in the elevator 100, which is acquired from the acceleration sensor 3B. When the acceleration acquisition unit 111 acquires the acceleration from the acceleration sensor 3B via the communication unit 11, the acceleration acquisition unit 111 determines whether the acceleration exceeds a predetermined threshold value. That is, the acceleration acquisition unit 111 determines whether or not the acquired acceleration is the acceleration generated by shaking.

When the acceleration acquisition unit 111 determines that the acquired acceleration exceeds a predetermined threshold value, the acceleration acquisition unit 111 specifies the magnitude of the acceleration (that is, the acceleration value). Typically, when the elevator 100 shakes, the acceleration acquisition unit 111 acquires a plurality of accelerations that exceed the threshold value. In this case, the acceleration acquisition unit 111 identifies the largest acceleration value.

Further, when the acceleration acquisition unit 111 determines that the acquired acceleration exceeds a predetermined threshold value, the acceleration acquisition unit 111 specifies the direction of the acceleration. Subsequently, the acceleration acquisition unit 111 uses the specified acceleration direction and the elevator azimuth information included in the layout information 121 to specify the shaking direction of the elevator 100 (hereinafter, referred to as “elevator shaking direction”). To do. The acceleration acquisition unit 111 specifies, for example, the angle of the acceleration direction with respect to the reference axis, which is determined based on the elevator azimuth information, as the elevator shaking direction. FIG. 4 is a top view of the elevator 100, and is a diagram showing a specific example of the elevator shaking direction. In the case of this example, the reference axis 91 is an axis parallel to the landing door 27 and the car door 28 of the elevator 100. The acceleration acquisition unit 111 specifies the angle 93 formed by the acquired acceleration direction 92 and the reference axis 91 as the elevator shaking direction.

Note that, typically, when the elevator 100 shakes, the acceleration acquisition unit 111 acquires a plurality of accelerations exceeding the threshold, but the acceleration acquisition unit 111 specifies only one elevator shaking direction. To do. For example, the acceleration acquisition unit 111 may specify an elevator sway direction by the above method for each of the acceleration directions, and calculate an average value of the identified elevator sway directions (that is, the angle 93). Further, for example, the acceleration acquisition unit 111 may specify the elevator sway direction by using the direction of the acceleration having the largest value.

Referring back to FIG. The car position acquisition unit 112 acquires the position of the car 23 in the hoistway 21 (hereinafter, sometimes simply referred to as “the position of the car 23 ”) when the shaking occurs. In the present embodiment, the car position acquisition unit 112 acquires the position of the car 23 based on the acceleration change history acquired from the acceleration sensor 3A.

Specifically, when the car position acquisition unit 112 acquires the acceleration from the acceleration sensor 3A via the communication unit 11, the car position acquisition unit 112 performs second-order integration using the acceleration acquisition interval (for example, 0.5 seconds). As a result, the amount of change in the position of the car 23 is calculated. The car position acquisition unit 112 identifies the position of the car 23 in the hoistway 21 based on the calculated position change amount and the layout information 121 and the car movement information 122 stored in the storage unit 12. To do. Specifically, the car position acquisition unit 112 reads, from the car movement information 122, the position of the car 23 indicated based on the floor, which is specified from the acceleration acquired last time. The car position acquisition unit 112 converts the position of the read car 23 into the height from the ground by referring to the layout information 121. The car position acquisition unit 112 specifies the height from the ground of the position based on the acceleration acquired this time by adding the calculated change amount to the height from the ground. The car position acquisition unit 112 refers to the height from the ground of each floor included in the layout information 121 and sets the height of the specified car 23 from the ground to the position of the car 23 indicated based on the floor. By converting, the position of the car 23 based on the acceleration acquired this time is calculated. Finally, the car position acquisition unit 112 adds the calculated position of the car 23 to the car movement information 122 (updates the car movement information 122). The car position acquisition unit 112 performs the above processing each time the acceleration is acquired from the acceleration sensor 3A.

When the car movement information 122 indicates the position of the car 23 by the height from the ground, the car position acquisition unit 112 reads the car movement information 122 from the car movement information 122 to update the car movement information 122. It is only necessary to calculate the position of the car 23 based on the acceleration acquired this time by adding the calculated change amount to the position of 23, and add the position of the car 23 to the car movement information 122.

When the car position acquisition unit 112 acquires the operation signal from the earthquake detector 2 via the communication unit 11, the car position acquisition unit 112 refers to the car movement information 122 and specifies the position of the nearest car 23. The car position acquisition unit 112 identifies the position of the car 23 as the position of the car 23 in the hoistway 21 when the shaking occurs.

The moving state acquisition unit 113 acquires the moving state of the car 23 at the time of shaking, that is, whether or not the car 23 was moving at the time of shaking. In the present embodiment, the movement state acquisition unit 113 refers to the car movement information 122 and specifies whether or not the car 23 has moved. Specifically, when the movement state acquisition unit 113 acquires an operation signal from the seismic sensor 2 via the communication unit 11, the movement state acquisition unit 113 refers to the car movement information 122 to determine whether or not the position of the car 23 has changed most recently. Identify. When the position of the car 23 has changed, the moving state acquisition unit 113 determines that the car 23 was moving when the shaking occurred. On the other hand, when the position of the car 23 has not changed, the moving state acquisition unit 113 determines that the car 23 has not moved when the shaking occurs.

The data acquisition unit 101 is acquired by the acceleration acquisition unit 111, the “swing magnitude” and the “elevator shake direction”, the car position acquisition unit 112 acquires the “position of the car 23 ”, and the movement state acquisition unit 113. The “whether or not the car 23 is moved” is output to the similar situation specifying unit 102 as “acquired data”. The acquired data also includes information indicating the date and time when the shaking occurred.

The similar situation specifying unit 102 specifies reference data indicating a shake similar to the shake received by the target elevator. That is, in the present embodiment, the similar situation specifying unit 102 specifies reference data that is similar to the shake that the elevator 100 is currently receiving and that indicates the shake that the elevator 100 has received in the past.

Specifically, when the similar situation identifying unit 102 acquires the acquired data from the data acquiring unit 101, the similar data specifying unit 102 acquires, from the reference data table 123, shake data similar to the shake data included in the acquired data, and the shake data included in the acquired data. The reference data including the event data similar to the event data to be read is read.

A specific example of this processing will be described with reference to FIG. FIG. 5A is a diagram showing a specific example of the reference data table 123, and FIG. 5B is a diagram showing a specific example of acquired data.

The reference data table 123 shown in FIG. 5A shows the date and time of the shaking, the magnitude of the shaking, the elevator shaking direction, the position of the car 23 when the shaking occurs, and the movement of the car 23 when the shaking occurs. It is a table that stores reference data in which the presence/absence, the determination result of the availability of the automatic diagnosis operation, and the inspection result data are associated with each other in time series.

A number for identifying each reference data (each row of the reference data table 123) is stored in the “number” column of the reference data table 123. Although a four-digit number is stored in the illustrated example, the information stored in this column is not limited to the illustrated example as long as the information can identify each reference data.

For example, the reference data with the number “1229” is, for a shake generated in the elevator 100, the date and time of the shake is “August 21, 2003 9:49”, the magnitude of the shake is “900 Gal”, and the direction of the shake. Is “80°”, the position of the car 23 when the shaking occurs is “4th floor”, the movement of the car 23 when the shaking occurs is “none”, and the determination result of whether or not the automatic diagnostic operation is “No”, It means that the inspection result is "abnormal".

Further, the reference data of the number “1230” indicates that, regarding the shaking generated in the elevator 100, the shaking occurrence date and time is “August 23, 2003 17:05”, the shaking magnitude is “480 Gal”, and the shaking direction is “25°”, the position of the car 23 when the shake occurs is “1st to 2nd floor”, the movement of the car 23 when the shake occurs is “Yes”, and the determination result of the automatic diagnostic operation is “No” , It means that the inspection result is “no abnormality”. Here, the position of the car 23 is "1st to 2nd floor". When the car 23 is moving from the 1st floor to the 2nd floor, shaking occurs, and then the car 23 stops on the 2nd floor. It represents.

Further, the reference data of the number “1231” indicates that, regarding the shaking generated in the elevator 100, the date and time of occurrence is “January 9, 2011 22:18”, the magnitude of shaking is “360 Gal”, and the direction of shaking is “12”. °", the position of the car 23 when the shake occurs is "10th floor", the movement of the car 23 when the shake occurs is "None", the result of judging whether or not the automatic diagnosis operation is possible is "OK", the inspection result Means "no abnormality".

In addition, the reference data of the number “1232” shows that, regarding the shaking generated in the elevator 100, the shaking occurrence date and time is “October 25, 2015 12:02”, the shaking magnitude is “320 Gal”, and the shaking direction is “97°”, the position of the car 23 when shaking occurred is “8th to 7th floor”, the movement of the car 23 when shaking occurred “Yes”, and the determination result of whether or not the automatic diagnostic operation is “OK” , It means that the inspection result is “no abnormality”. Here, when the position of the car 23 is "8th to 7th floor", a sway occurred when the car 23 was moving from the 8th floor to the 7th floor, and then the car 23 stopped on the 7th floor. It represents.

Further, the reference data with the number “1233” indicates that, regarding the shaking generated in the elevator 100, the shaking occurrence date and time is “November 1, 2015 4:32”, the shaking magnitude is “620 Gal”, and the shaking direction is "93°", the position of the car 23 when the shaking occurred is "1st floor", the movement of the car 23 when the shaking occurred is "None", the determination result of whether or not the automatic diagnosis operation is "No", the inspection It means that the result is "abnormal".

Further, the acquired data shown in FIG. 5B shows that, regarding the shaking generated in the elevator 100, the shaking occurrence date and time is “July 24, 2017 9:51”, the shaking magnitude is “350 Gal”, and the shaking is It means that the direction of “15°” is “15°”, the position of the car 23 when the shaking occurs is “10th floor”, and the movement of the car 23 when the shaking occurs is “none”.

Here, it is assumed that the similar situation specifying unit 102 has acquired the acquisition data shown in FIG. 5B from the data acquiring unit 101. The similar situation identifying unit 102 identifies, for example, one or a plurality of reference data that include, from among the reference data included in the reference data table 123, the shake data whose value is larger than the shake data included in the acquired data. Then, the similarity status identifying unit 102 identifies one reference data item that is most similar to the acquired data item from the identified reference data items.

Here, an example of a method of identifying the reference data most similar to the acquired data will be described. The similarity status identifying unit 102 identifies reference data that satisfies the following four conditions as reference data that is most similar to the acquired data. (1) The difference between the magnitude of the shake included in the reference data and the magnitude of the shake included in the acquired data is within a predetermined value (for example, within 40 Gal). (2) The difference between the elevator shaking direction included in the reference data and the elevator shaking direction included in the acquired data is within a predetermined value (for example, within 10°). (3) Whether the position of the car 23 included in the reference data is within the resonance range and whether the position of the car 23 included in the acquired data is within the resonance range match. (4) The presence or absence of movement of the car 23 included in the reference data matches the presence or absence of movement of the car 23 included in the acquired data. For example, when the acquired data shown in FIG. 5B is acquired, the similarity status specifying unit 102 has the number “1231” among the reference data included in the reference data table 123 based on this specifying method. Reference data (reference data surrounded by a broken line in (a) of FIG. 5) is specified.

In the above condition (3), the resonance range is a range in which the rope 24 is likely to resonate when shaking occurs when the position of the car 23 is within that range. On the other hand, the non-resonance range is a range in which the rope is hard to resonate even if shaking occurs when the position of the car 23 is within the range. Typically, the resonance range and the non-resonance range are ranges including the positions of the hoistway 21 corresponding to a plurality of floors and the positions of the hoistway 21 corresponding to the floors. For example, when the resonance range is from the third floor to the fifth floor, the resonance range corresponds to each of the third floor, the third floor, the third floor, the fourth floor, the fourth floor, the fifth floor, and the fifth floor. The position of the hoistway 21 is included. This also applies to the non-resonant range. The resonance range and the non-resonance range are determined in advance based on the natural period of the building in which the elevator 100 is installed and the specifications of the elevator 100, and are included in the layout information 121. The similar situation specifying unit 102 refers to the layout information 121 and specifies whether or not the position of the car 23 in the acquired data and the reference data is in the resonance range.

In addition, when there are a plurality of pieces of reference data that satisfy the above four conditions, the similar situation identifying unit 102 may identify the reference data whose swing magnitude and elevator swing direction are most similar to the acquired data. Note that the numerical values exemplified as the predetermined values in the above conditions (1) and (2) are examples, and the present invention is not limited to this example. Further, the condition regarding the position of the car 23 when the shaking occurs may be, for example, the condition that the position of the car 23 included in the reference data matches the position of the car 23 included in the acquired data.

Referring back to FIG. The similarity status identifying unit 102 reads out the identified reference data that is most similar to the acquired data, and outputs it to the operation control unit 103. In addition, when the similar situation specific|specification part 102 cannot specify the reference data most similar to acquired data, it is desirable to notify the operation control part 103 of that, and it is not made to perform automatic diagnosis temporary restoration operation. Further, the similar situation specifying unit 102 outputs the acquired data to the associating unit 104.

The operation control unit 103 controls the operation of the elevator. Specifically, the operation control unit 103 transmits a drive signal to the elevator drive unit 4 of the elevator 100 to drive the elevator drive unit 4. The elevator drive unit 4 is a general term for each unit of the elevator 100 that is driven by the control of the control panel 1. Specific examples of the elevator drive unit 4 include a hoisting machine 26, a landing door 27, and a car door 28, but are not limited to this example. When the operation control unit 103 acquires the operation signal from the earthquake detector 2, the operation control unit 103 stops the operation of the elevator 100.

The operation control unit 103 includes a diagnostic operation control unit 131 (operation allowance unit). The diagnostic operation control unit 131 controls automatic diagnostic operation for temporary restoration. When the diagnostic operation control unit 131 acquires the operation signals from all the earthquake sensors 2 from the data acquisition unit 101, the diagnostic operation control unit 131 is in a state of waiting for the output from the similar situation specifying unit 102. When the diagnostic operation control unit 131 acquires the reference data from the similar situation specifying unit 102, whether the inspection result data included in the reference data indicates that the elevator 100 has no abnormality (that is, in FIG. 5). It is determined whether or not "no abnormality" shown is stored. When it is determined that the elevator 100 has no abnormality, the diagnostic operation control unit 131 permits execution of the automatic diagnostic provisional recovery operation. This is because there is no abnormality in the elevator 100 due to similar swaying in the past, and it is unlikely that the swaying this time also has an anomaly that affects the execution of the automatic diagnosis temporary restoration operation.

Subsequently, the diagnostic operation control unit 131 causes the automatic diagnostic operation other than "the inspection result data included in the reference data indicates that the elevator 100 has no abnormality" (hereinafter, simply "other It is determined whether or not the condition is satisfied.). The other conditions are, for example, that the safety device of the elevator is not operating, is stopped on one of the floors, and the like, but is not limited to this example. Note that the safety device may include a safety device having low relevance to an earthquake (for example, a device that stops the car 23 when the car door 28 is opened while the car 23 is moving).

When it is determined that the other conditions are satisfied, the diagnostic operation control unit 131 controls the elevator drive unit 4 to start the automatic diagnostic operation. That is, the diagnostic operation control unit 131, even when the high setting sensor operates, when the condition that no abnormality has occurred due to similar sway in the past and the other conditions are satisfied, the automatic diagnostic operation control unit 131 performs the automatic diagnostic operation. To execute. For example, when the reference data with the number “1231” shown in FIG. 5A is acquired, the inspection result data of the reference data is “no abnormality”, and therefore the diagnostic operation control unit 131 uses the other conditions. When it is determined that the above condition is satisfied, the elevator 100 starts the automatic diagnosis operation.

On the other hand, when the inspection result data included in the reference data acquired from the similar situation specifying unit 102 indicates that the elevator 100 has an abnormality (when “abnormality” shown in FIG. 5 is stored), The diagnostic operation control unit 131 does not execute the automatic diagnostic operation. Further, even if the inspection result data indicates that the elevator 100 has no abnormality, when it is determined that one of the other conditions is not satisfied, the diagnostic operation control unit 131 does not execute the automatic diagnostic operation. .. Further, the diagnostic operation control unit 131 does not execute the automatic diagnostic operation even when the notification that the reference data most similar to the acquired data cannot be specified is acquired from the similar situation specifying unit 102.

When the diagnostic operation control unit 131 acquires the operation signals from the P-wave sensor and the low setting sensor, whether the other conditions described above are satisfied without waiting for the output from the similar situation specifying unit 102. To judge. When the diagnostic operation control unit 131 determines that the other conditions are satisfied, the diagnostic operation control unit 131 controls the elevator drive unit 4 to start the automatic diagnostic operation. On the other hand, when determining that the other conditions are not satisfied, the diagnostic operation control unit 131 does not execute the automatic diagnostic operation.

Further, when the operation signal from only the P-wave sensor is acquired, the operation control unit 103 stops the elevator drive unit 4 for a predetermined time and then restarts the normal operation.

The diagnostic operation control unit 131 outputs information indicating whether or not the automatic diagnostic operation is executed (diagnostic operation availability) to the associating unit 104. In addition, the diagnostic operation control unit 131 responds to information (hereinafter, referred to as “diagnosis result”) indicating whether or not an abnormality to the extent that temporary recovery operation cannot be performed is detected by the automatic diagnostic operation when the automatic diagnostic operation ends. Output to the attachment unit 104.

The associating unit 104 creates reference data based on the shaking generated in the elevator 100, and updates the reference data table 123. Specifically, when the associating unit 104 acquires the acquired data from the similar situation specifying unit 102, it waits for the diagnostic operation control unit 131 to acquire whether or not the diagnostic operation is possible. Upon acquisition of the diagnostic operation availability, the association unit 104 associates the acquired acquisition data with the diagnostic operation availability to generate reference data, and stores the reference data in the reference data table 123. This reference data is unfinished data in which information is not stored in the "inspection result" column.

Further, when the associating unit 104 acquires the diagnostic result from the diagnostic operation control unit 131, the associating unit 104 stores the diagnostic result in the “inspection result” column as inspection result data. In addition, the associating unit 104, via the communication unit 11, information indicating the inspection result of the elevator 100 by a specialist engineer (hereinafter, referred to as “inspection result”. In other words, indicates whether or not there is an abnormality in the elevator 100. Information) is received from the information processing device 5, the inspection result is stored in the “inspection result” column as inspection result data. That is, the inspection result data includes the above-mentioned diagnosis result and inspection result. If the diagnosis result is already stored when the inspection result is stored, the associating unit 104 overwrites the diagnosis result with the inspection result. This is because the inspection result by the professional engineer is more accurate as the information indicating the presence/absence of abnormality of the elevator 100 than the diagnosis result.

The information processing device 5 is typically a personal computer used by a professional engineer. When the inspection of the elevator 100 is completed, the professional engineer inputs information indicating the presence or absence of abnormality to the information processing device 5 and transmits it to the control panel 1.

(Process flow executed by control panel 1)
FIG. 6 is the first half of the flowchart showing an example of the flow of processing executed by the control panel 1. FIG. 7 is the latter half of the flowchart showing an example of the flow of processing executed by the control panel shown in FIG. Here, in order to distinguish between the automatic diagnosis operation and the temporary restoration operation, the normal operation of the elevator 100 is referred to as “normal operation”.

The operation control unit 103 starts the normal operation of the elevator 100 (S1). The operation control unit 103 is on standby to receive the inspection signal (S2). The inspection signal is a signal transmitted to the operation control unit 103 via the communication unit 11 when an inspection switch (not shown) is turned from OFF to ON. The inspection switch is provided in an operation panel box (not shown) provided in the car 23.

When the data acquisition unit 101 acquires an operation signal from the P-wave sensor (YES in S3) while the operation control unit 103 has not received the inspection signal (NO in S2), the data acquisition unit 101 causes the operation to be performed. The signal is output to the operation control unit 103. When the operation control unit 103 acquires the operation signal, the operation control unit 103 stops the operation of the elevator 100 (S4).

When the data acquisition unit 101 further acquires the operation signal from the low setting sensor (YES in S5), the data acquisition unit 101 waits until a predetermined time has elapsed (S6). The predetermined time is a time period during which the building continues to shake due to an earthquake, and is typically about 5 to 10 minutes, although it depends on the height of the building. That is, when the data acquisition unit 101 acquires the operation signal from the low setting sensor, the data acquisition unit 101 waits until the shaking stops. When the predetermined time has elapsed (YES in S6), the data acquisition unit 101 determines whether the operation signal from the high setting sensor is acquired (S7). When the operation signal from the high setting sensor is acquired (YES in S7), the data acquisition unit 101 acquires shake data and event data (S8). In the present embodiment, the data acquisition unit 101 acquires the magnitude of the sway, the direction of the sway of the elevator, the position of the car 23, and the presence/absence of movement of the car 23, and generates acquired data in association with the date and time of the sway, and the similarity It is output to the situation specifying unit 102.

Subsequently, when the similar situation specifying unit 102 acquires the acquired data, the similar situation specifying unit 102 refers to the reference data table 123 as shown in FIG. 7, and specifies the reference data indicating the similar shaking in the past (S21). The similar situation identifying unit 102 outputs the identified reference data to the diagnostic operation control unit 131. Further, the similarity status specifying unit 102 outputs the acquired acquisition data to the associating unit 104.

When the diagnostic operation control unit 131 acquires the reference data, the diagnostic operation control unit 131 determines whether the inspection result data included in the reference data is “no abnormality” (S22). When it is determined that there is "no abnormality" (YES in S22), the diagnostic operation control unit 131 determines whether or not other conditions regarding the availability of automatic diagnostic operation are satisfied (S23). When it is determined that the condition is satisfied (YES in S23), the diagnostic operation control unit 131 causes the elevator 100 to start the automatic diagnostic operation (S24). Further, the diagnostic operation control unit 131 outputs information indicating whether or not automatic diagnosis has been executed (diagnostic operation availability) to the associating unit 104. The associating unit 104 stores the acquired diagnostic operation availability and the acquired data as reference data (S25). Specifically, the associating unit 104 associates the acquired diagnostic operation availability and the acquired data with each other to generate reference data, and stores the reference data in the reference data table 123.

The diagnostic operation control unit 131 detects an abnormality in the elevator 100 during the automatic diagnostic operation (S26). When the automatic diagnosis operation ends (YES in S27) without any abnormality being detected (YES in S26), the diagnostic operation control unit 131 outputs information (diagnosis result) indicating whether or not an abnormality is detected in the automatic diagnosis operation. Output to the associating unit 104. In this case, the diagnostic operation control unit 131 outputs a diagnostic result indicating that no abnormality is found in the automatic diagnostic operation. When the associating unit 104 acquires the diagnostic result from the diagnostic operation control unit 131, the associating unit 104 adds the diagnostic result as inspection result data to the generated reference data (S28). Subsequently, the diagnostic operation control unit 131 temporarily restores the elevator 100 and restarts the operation (S29). The operation control unit 103 automatically resets the P-wave sensor and the S-wave sensor by transmitting a signal to the P-wave sensor and the S-wave sensor (S30). Then, the processing executed by the control panel 1 returns to step S2 shown in FIG.

A specialist engineer opens the operation panel box and switches the inspection switch from OFF to ON in order to perform an inspection for the main restoration of the elevator 100. Also, like the inspection switch, the operation switch in the control panel box is switched from automatic operation to manual operation. As a result, the inspection signal is transmitted to the control panel 1. When the operation control unit 103 acquires the inspection signal (YES in S2), the operation control unit 103 stops the operation of the elevator 100 (S16).

When the inspection is completed, the professional engineer inputs the inspection result to the information processing device 5 and transmits it to the control panel 1. When the associating unit 104 receives the inspection result via the communication unit 11 (S17), the associating unit 104 adds the inspection result as inspection result data to the generated reference data (S18).

When no abnormality is found in the inspection by the expert engineer (YES in S19), the expert engineer switches the inspection switch from ON to OFF and switches the operation switch from the manual operation to the automatic operation. As a result, a signal for starting normal operation is transmitted to the control panel 1. When the operation control unit 103 acquires the signal, the operation control unit 103 restarts the normal operation of the elevator 100 (S20). In this case, since all the seismic detectors 2 have already been reset, even if a signal is transmitted in step S30, the seismic detectors 2 are not automatically reset. Alternatively, if the control panel 1 holds information indicating whether or not the automatic reset of the earthquake sensor 2 is performed and the information indicates that the automatic reset is performed, the operation control unit 103 determines that The configuration may be such that no signal is transmitted to the sensor 2. In this case, step S30 is omitted.

In step S5, when the data acquisition unit 101 has not acquired the operation signal from the low setting sensor (NO in S5), the data acquisition unit 101 waits until a predetermined time has elapsed (step S11). The predetermined time is a time lag from detecting the P wave to detecting the S wave, and is typically about 45 to 60 seconds. That is, when the data acquisition unit 101 acquires the operation signal from the P wave sensor, the data acquisition unit 101 waits until it can be specified that the S wave does not come. When the operation signal from the low setting sensor is not acquired before the predetermined time has elapsed (YES in S11), the data acquisition unit 101 notifies the operation control unit 103 that the predetermined time has elapsed. Upon receiving the notification from the data acquisition unit 101, the operation control unit 103 determines whether the temporary recovery operation is in progress (S12). When the temporary recovery operation is being performed (YES in S12), the operation control unit 103 restarts the temporary recovery operation (S13). On the other hand, if the temporary recovery operation is not being performed (NO in S12), that is, if the normal operation is being performed, the operation control unit 103 restarts the normal operation (S14). Then, the operation control unit 103 resets the P wave sensor by transmitting a signal to the P wave sensor (S15). Then, the processing executed by the control panel 1 returns to step S2 shown in FIG.

In step S7, when the operation signal from the high setting sensor is not acquired (NO in S7), the process executed by the control panel 1 proceeds to step S23 shown in FIG. Specifically, the data acquisition unit 101 outputs the operation signal from the low setting sensor to the operation control unit 103. Then, the operation control unit 103 determines whether or not other conditions regarding the availability of the automatic diagnosis operation are satisfied.

In step S22, when the diagnostic operation control unit 131 determines that the inspection result data included in the acquired reference data is not “no abnormality” (that is, “abnormality”) (NO in S22), the control panel The process executed by 1 proceeds to step S17 shown in FIG. That is, the elevator 100 is in a state of waiting for the inspection by the specialist engineer without the diagnostic operation control unit 131 performing the diagnostic operation. This is the same when the diagnostic operation control unit 131 determines in step S23 that the other conditions regarding the availability of the automatic diagnostic operation are not satisfied (NO in S23).

In step S26, when the abnormality of the elevator 100 is detected in the automatic diagnosis operation (NO in S26), the diagnostic operation control unit 131 ends the automatic diagnosis operation of the elevator 100 (S31), and the abnormality is detected in the automatic diagnosis operation. Information (diagnosis result) indicating whether or not it is found is output to the association unit 104. In this case, the diagnostic operation control unit 131 outputs a diagnostic result indicating that an abnormality has been found in the automatic diagnostic operation. When the associating unit 104 acquires the diagnostic result from the diagnostic operation control unit 131, the associating unit 104 adds the diagnostic result as inspection result data to the generated reference data (S32). Subsequently, the diagnostic operation control unit 131 stops the operation of the elevator 100 (S33). Then, the processing executed by the control panel 1 proceeds to step S17 shown in FIG.

As described above, the control panel 1 according to the present embodiment is similar to the shake that occurs this time even when the operation signal from the high setting sensor, which basically cannot perform the automatic diagnosis operation, is acquired. However, when there is no abnormality in the elevator 100 due to the shaking that occurred in the past, exceptionally, the execution of the automatic diagnosis temporary restoration operation is permitted. As a result, the elevator in which no abnormality has occurred can be temporarily restored, so that the operation of the elevator can be restarted quickly. Further, since the elevator in which no abnormality has occurred can be restored (temporary restoration) without inspection by a specialist engineer, the specialist engineer can lower the priority of such elevator inspection. Therefore, the number of elevators that need to be inspected promptly is reduced, and the burden on the specialist can be reduced.

[Embodiment 2]
Another embodiment of the present invention will be described below. For convenience of description, members having the same functions as the members described in the above embodiment will be designated by the same reference numerals, and the description thereof will be omitted.

FIG. 8 is a block diagram showing an example of the main configuration of the management server 7 (information processing apparatus) according to this embodiment. As illustrated, the management server 7 is communicably connected to a plurality of elevators (elevators 200A, 200B, and 200C in the illustrated example). The plurality of elevators are elevators installed in a predetermined area. The predetermined area is, for example, the same city, a predetermined range including an elevator maintenance company, or the like, but is not limited to this example. In the following description, if the elevators 200A, 200B, and 200C are not distinguished, they may be collectively referred to as the elevator 200.

The management server 7 identifies, based on the acquired data obtained from the elevator 200, reference data indicating a shake that has occurred in any of the elevators 200 in the past, which is similar to the shake that has occurred in each of the elevators 200. Then, based on the reference data, it is determined whether or not to allow execution of the automatic diagnosis temporary restoration operation of each elevator 200. The main configuration of the management server 7 will be described later.

(Structure of main part of control panel 1a)
FIG. 9 is a block diagram showing an example of the main configuration of the control panel 1 a included in the elevator 200. As illustrated, unlike the control panel 1 described in the first embodiment, the control panel 1a includes a control unit 10a and a storage unit 12a instead of the control unit 10 and the storage unit 12. Unlike the storage unit 12, the storage unit 12a does not store the reference data table 123.

Unlike the control unit 10, the control unit 10a includes a data acquisition unit 101a and an operation control unit 103a instead of the data acquisition unit 101 and the operation control unit 103. Further, unlike the control unit 10, the control unit 10a does not include the similar situation specifying unit 102 and the associating unit 104.

Similar to the data acquisition unit 101, the data acquisition unit 101a includes an acceleration acquisition unit 111 (first acquisition unit, second acquisition unit), a car position acquisition unit 112 (second acquisition unit), and a movement state acquisition unit 113 (first 2 acquisition part) is included. The data acquisition unit 101a is different from the data acquisition unit 101 in that the acquired data is transmitted to the management server 7 via the communication unit 11, and the other points are the same as the data acquisition unit 101. In addition, the acquired data of the present embodiment includes information indicating the magnitude of shaking, the direction of shaking of the elevator, the position of the car 23, the presence or absence of movement of the car 23, and the date and time of occurrence of shaking, as well as the elevator for identifying the elevator 200. Contains identification information.

The operation control unit 103a controls the operation of the elevator, similarly to the operation control unit 103. The operation control unit 103a includes a diagnostic operation control unit 131a. The diagnostic operation control unit 131a controls the automatic diagnostic operation for the temporary recovery, like the diagnostic operation control unit 131. The difference between the diagnostic operation control unit 131a and the diagnostic operation control unit 131 is that it is determined whether the inspection result data included in the reference data indicates that the elevator 200 has no abnormality, in other words, automatic diagnosis temporary restoration. The point is that the determination as to whether or not the execution of the operation is permitted is not performed. Specifically, the determination is performed by the management server 7, and the diagnostic operation control unit 131a waits for the notification indicating the determination result transmitted from the management server 7 (hereinafter, referred to as “determination result notification”). When the received determination result notification is a notification indicating that execution of the automatic diagnosis provisional recovery operation is permitted (hereinafter, referred to as “diagnosis operation permission notification”), the diagnosis operation control unit 131a satisfies other conditions. If it is determined that the condition is satisfied, the elevator 200 is caused to start the automatic diagnosis operation. On the other hand, when the received determination result notification is a notification indicating that execution of the automatic diagnosis temporary recovery operation is not permitted (hereinafter, referred to as “diagnosis operation disapproval notification”), the diagnostic operation control unit 131a determines that the automatic diagnosis operation is being performed. Do not do. Further, the diagnostic operation control unit 131a transmits the diagnostic operation availability and the diagnostic result to the management server 7 via the communication unit 11.

(Main configuration of management server 7)
Referring again to FIG. 8, the main configuration of the management server 7 will be described. As illustrated, the management server 7 includes a control unit 70, a communication unit 71 (first acquisition unit, second acquisition unit), and a storage unit 72. The control unit 70 centrally controls each unit of the management server 7. The communication unit 71 connects to a device outside the management server 7 so as to be able to communicate by wire or wirelessly, and acquires data from the device. The communication unit 11 acquires, for example, the acquisition data transmitted from the control panel 1a of the elevator 200. The storage unit 72 stores various data used by the management server 7. The storage unit 72 stores at least a reference data table 721.

The reference data table 721 is a table for storing reference data, like the reference data table 123 described in the first embodiment. In the present embodiment, the elevator that has undergone the sway indicated by the reference data (reference elevator) is one of the elevators 200. That is, the reference elevator according to the present embodiment may be the same elevator 200 as the elevator 200 (target elevator) that has transmitted the acquired data, or may be a different elevator 200. In other words, the reference data table according to the present embodiment is the sway data indicating the sway magnitude at which the high-setting sensor (or the earthquake sensor 2 with the [diagnosis] setting) received by each elevator 200 in the past operates. And reference data in which the inspection result data indicating the inspection result of each elevator 200 after the shaking is associated are stored.

As shown in FIG. 8, the control unit 70 includes a similar situation identification unit 701 (identification unit), a diagnostic operation determination unit 702 (operation allowance unit), and an association unit 703.

Similar to the similar situation specifying unit 102, the similar situation specifying unit 701 specifies reference data indicating a shake similar to the shake received by the target elevator. For example, when the target elevator is the elevator 200A, the similar situation identifying unit 701 obtains not only the reference data of the elevator 200A but also the reference data indicating the shake similar to the shake received by the elevator 200A from the reference data of all the elevators 200A. Identify.

10A is a diagram showing a specific example of the reference data table 721, and FIG. 10B is a diagram showing a specific example of the acquired data. As shown in FIG. 10A, the reference data according to the present embodiment is the reference data described in the first embodiment including elevator identification information. As shown in FIG. 10, the position of the car 23 in the reference data and the acquired data according to the present embodiment indicates whether the position of the car 23 is within the resonance range or within the non-resonance range. Information is associated. As a result, the similarity determining unit 701 simply compares the reference data and the acquired data, and determines whether the position of the car 23 included in the reference data is within the resonance range and the position of the car 23 included in the acquired data. It is possible to determine whether or not the condition "is within the resonance range and is matched" is satisfied. Further, in the example of FIG. 10, the member number given to the elevator in FIG. 8 is used as the elevator identification information, but the elevator identification information is not limited to this example.

For example, the reference data with the number “7209” is, for a shake occurring in the elevator 200A, the date and time of occurrence of the shake is “April 9, 2010 2:11”, the magnitude of the shake is “380 Gal”, and the direction of the shake. Is “80°”, the position of the car 23 at the time of shaking is “on the first floor and within the resonance range”, the movement of the car 23 at the time of shaking is “none”, determination of whether automatic diagnostic operation is possible It means that the result is “No” and the inspection result is “Abnormal”.

Further, the reference data with the number “7210” indicates that, regarding the shaking generated in the elevator 200B, the shaking occurrence date and time is “April 9, 2010 2:11”, the shaking magnitude is “390 Gal”, and the shaking direction. Is “64°”, the position of the car 23 at the time of shaking is “7th to 8th floor and within the non-resonance range”, the movement of the car 23 at the time of shaking is “Yes”, It means that the result of the determination is “No” and the result of the inspection is “No abnormality”. Here, when the position of the car 23 is "7th to 8th floor", a sway occurred when the car 23 was moving from the 7th floor to the 8th floor, and then the car 23 stopped on the 8th floor. It represents.

In addition, the reference data with the number “7211” indicates that, regarding the shaking generated in the elevator 200C, the shaking occurrence date and time is “April 9, 2010 2:11”, the shaking magnitude is “355 Gal”, and the shaking direction. Is "17°", the position of the car 23 when the shaking occurs is "10th floor, within the non-resonance range", the movement of the car 23 when the shaking occurs is "none", and whether automatic diagnostic operation is possible or not It means that the judgment result is “OK” and the inspection result is “No abnormality”.

In addition, the reference data with the number “7239” indicates that the shaking occurrence date and time is “September 22, 2014, 13:54”, the magnitude of the shaking is “365 Gal”, and the shaking direction regarding the shaking that has occurred in the elevator 200A. Is “22°”, the position of the car 23 at the time of shaking is “6 to 5th floor and within the resonance range”, the movement of the car 23 at the time of shaking is “Yes”, whether automatic diagnostic operation is possible or not It means that the judgment result is “OK” and the inspection result is “No abnormality”. Here, the position of the car 23 is "6th to 5th floors". When the car 23 is moving from the 6th floor to the 5th floor, swaying occurs, and then the car 23 stops on the 5th floor. It represents.

In addition, the reference data with the number “7240” indicates that, regarding the shaking that occurred in the elevator 200B, the shaking occurrence date and time was “September 22, 2014, 13:54”, the shaking magnitude was “330 Gal”, and the shaking direction. Is “39°”, the position of the car 23 at the time of shaking is “10th floor and within the non-resonance range”, the movement of the car 23 at the time of shaking is “none”, and whether automatic diagnostic operation is possible or not It means that the judgment result is “OK” and the inspection result is “No abnormality”.

Further, the reference data with the number “7241” is, for the shaking generated in the elevator 200C, the shaking occurrence date and time is “September 22, 2014 13:54”, the shaking magnitude is “345 Gal”, and the shaking direction. Is “92°”, the position of the car 23 at the time of shaking is “on the first floor and within the resonance range”, the movement of the car 23 at the time of shaking is “none”, determination of whether automatic diagnostic operation is possible It means that the result is “No” and the inspection result is “No abnormality”.

The acquired data shown in (b) of FIG. 10 shows that, regarding the shaking generated in the elevator 200A, the shaking occurrence date and time is “July 24, 2017 9:51”, the shaking magnitude is “350 Gal”, and the shaking is Means "15°", the position of the car 23 at the time of shaking is "10th floor, within the non-resonance range", and the movement of the car 23 at the time of shaking is "none". doing.

The similar situation specifying unit 701 specifies one reference data by the same method as the similar situation specifying unit 102, for example. This identification method has been described in the first embodiment, and thus the description thereof is omitted here. For example, when the acquisition data shown in (b) of FIG. 10 is acquired, the similar situation identifying unit 701 uses the identification method as the reference data (the broken line in (a) of FIG. 10 indicates the number “7211”). Specify the reference data enclosed in.

The similarity status identifying unit 701 reads out the identified reference data that is most similar to the acquired data, associates the elevator identification information included in the acquired data, and outputs the associated reference data to the diagnostic operation determination unit 702. When the reference data that is most similar to the acquired data cannot be specified, the similar situation specifying unit 701 preferably notifies the diagnostic operation determining unit 702 of that fact and does not allow the execution of the automatic diagnosis temporary recovery operation. .. Further, the similar situation specifying unit 701 outputs the acquired data to the associating unit 703.

The conditions for the similarity determining unit 701 to specify the reference data most similar to the acquired data are not limited to the four conditions described in the first embodiment. For example, in addition to the four conditions (or in place of any of the above four conditions), there may be a condition that “the height of the building in which the elevator 200 is installed is almost the same”. When this condition exists, the acquired data and the reference data include information indicating the height of the building. The information may be, for example, a number indicating the number of floors of the top floor of the building. In this case, the condition that “the heights of the buildings in which the elevators 200 are installed are almost the same” may be the condition that “the numbers indicating the number of floors at the top floor are the same”. The information indicating the height of the building may be included in the layout information 121 stored in the storage unit 12a of the elevator 200. The data acquisition unit 101a reads the information from the layout information 121 and acquires the acquired data. Should be included in.

The diagnostic operation determination unit 702 determines whether to allow execution of the automatic diagnostic provisional recovery operation of the target elevator. When the diagnostic operation determination unit 702 acquires the reference data from the similar situation identification unit 701, whether or not the inspection result data included in the reference data indicates that the elevator 200 has no abnormality (“shown in FIG. 10”). It is determined whether "no abnormality" is stored), and a determination result notification is transmitted to the elevator 200. When it is determined that the elevator 200 has no abnormality, the diagnostic operation determination unit 702 allows the automatic diagnostic provisional recovery operation to be performed. Then, the diagnostic operation determination unit 702 transmits the diagnostic operation permission notification to the elevator indicated by the elevator identification information acquired together with the reference data via the communication unit 71. On the other hand, when the inspection result data included in the reference data acquired from the similarity determining unit 701 indicates that the elevator 200 has an abnormality (when “abnormality” illustrated in FIG. 10 is stored), The diagnostic operation determination unit 702 does not allow execution of the automatic diagnostic provisional recovery operation. Then, the diagnostic operation determination unit 702 transmits the diagnostic operation disapproval notification to the elevator indicated by the elevator identification information acquired together with the reference data, via the communication unit 71.

For example, when the reference data with the number “7211” shown in FIG. 10A is acquired, the inspection result data of the reference data is “no abnormality”, so the diagnostic operation determination unit 702 causes the elevator 200 Send the diagnostic operation permission notification.

The associating unit 703 generates reference data based on the shaking generated in the elevator 200, and updates the reference data table 721. The associating unit 703 generates the associative data by the same method as the associating unit 104, for example. Since the method has been described in the first embodiment, the description here is omitted.

(Flow of processing executed by the control panel 1a)
FIG. 11 is the first half (acquired data transmission process) of the flowchart showing an example of the flow of the process executed by the control panel 1a. Note that, in FIG. 11, steps showing the same processing as in FIG. 6 are given the same step numbers as in FIG. Further, description of steps showing the same processing as in FIG. 6 will be omitted here.

The data acquisition unit 101a transmits the acquired data acquired in step S8 to the management server 7 via the communication unit 11 (S41).

Note that the elevator 200 according to the present embodiment executes the process of step S19 without executing the processes of steps S17 and S18 shown in FIG. 6 after executing the process of step S16.

FIG. 12 is the latter half (operation restart process) of the flowchart showing an example of the flow of the process executed by the control panel 1a. Note that, in FIG. 12, steps showing the same processing as in FIG. 7 are given the same step numbers as in FIG. 7. Further, description of steps showing the same processing as in FIG. 7 will be omitted here.

The diagnostic operation control unit 131a is on standby to receive the determination result notification (S51). Upon receiving the determination result notification (YES in S51), the diagnostic operation control unit 131a determines whether the determination result notification is a diagnostic operation permission notification (S52). When the received determination result notification is the diagnostic operation permission notification (YES in S51), the diagnostic operation control unit 131a executes the processes of steps S23 and S24. Then, the diagnostic operation control unit 131a transmits the availability of the diagnostic operation to the management server 7 via the communication unit 11 (S53). Then, the diagnostic operation control unit 131a executes the processes of steps S26 and S27. Then, the diagnostic operation control unit 131a transmits the diagnostic result to the management server 7 via the communication unit 11 (S54). In this case, the diagnostic operation control unit 131a transmits a diagnostic result indicating that no abnormality is found in the automatic diagnostic operation. After that, the diagnostic operation control unit 131a executes the process of step S29, and then the operation control unit 103a executes the process of step S30. With the above, the operation restart processing ends, and the acquired data transmission processing returns to step S2 shown in FIG.

In step S52, when the received determination result notification is the diagnostic operation disapproval notification (NO in S52), the diagnostic operation control unit 131a ends the operation restart process. Then, the acquired data transmission process proceeds to step S19 shown in FIG. That is, in the elevator 200, the diagnostic operation control unit 131a does not execute the diagnostic operation and is in a state of waiting for the inspection by the professional engineer.

After executing the process of step S31, the diagnostic operation control unit 131a transmits the diagnosis result to the management server 7 via the communication unit 11 (S55).

(Flow of processing executed by the management server 7)
FIG. 13 is a flowchart showing an example of the flow of the diagnostic operation determination process executed by the management server 7. First, the similar situation specifying unit 701 is on standby to receive the acquired data transmitted from the elevator 200 (S61). When the acquired data is received via the communication unit 71 (YES in S61), the similar situation specifying unit 701 refers to the reference data table 721 and specifies the reference data indicating the similar shaking in the past (S62). The similar situation identifying unit 701 associates the identified reference data with the elevator identification information included in the acquired data, and outputs the reference data to the diagnostic operation determining unit 702. Further, the similar situation specifying unit 701 outputs the acquired data to the associating unit 703.

When the diagnostic operation determination unit 702 acquires the reference data, the diagnostic operation determination unit 702 determines whether the inspection result data included in the reference data is “no abnormality” (S63). When it is determined that there is “no abnormality” (YES in S63), the diagnostic operation determination unit 702 transmits the diagnostic operation permission notification to the elevator 200 (target elevator) indicated by the elevator identification information via the communication unit 71 ( S64). On the other hand, when it is determined that there is no "abnormality" (NO in S63), the diagnostic operation determination unit 702 transmits the diagnostic operation disapproval notification to the elevator 200 (target elevator) indicated by the elevator identification information via the communication unit 71. Yes (S65).

FIG. 14 is a flowchart showing an example of the flow of reference data generation processing executed by the management server 7. First, the associating unit 703 stands by to receive the diagnostic operation availability transmitted from the elevator 200 (S71). When the diagnostic operation availability is received via the communication unit 71 (YES in S71), the associating unit 703 stores the received diagnostic operation availability and the acquired acquired data as reference data (S72). Specifically, the associating unit 703 associates the diagnostic operation availability and the acquired data to generate reference data, and stores the reference data in the reference data table 721.

When the diagnosis unit 703 acquires the diagnosis result from the elevator 200 via the communication unit 71 (YES in S73), the associating unit 703 adds the diagnosis result as inspection result data to the generated reference data (S74). On the other hand, when the diagnosis result is not acquired from the elevator 200 (NO in S73), the associating unit 703 omits the process of step S74.

Subsequently, the associating unit 703 is in a state of waiting for reception of information (inspection result) indicating the inspection result by the professional engineer, which is transmitted from the information processing device 5 for the generated reference data (S75). When the association unit 703 receives the information via the communication unit 71 (YES in S75), the inspection result is added to the generated reference data as inspection result data (S76).

As described above, the management server 7 according to the present embodiment, from the reference data in the plurality of elevators installed in the predetermined area, the reference data indicating the shake that has occurred in the past, which is similar to the shake that the target elevator has received. Identify. As a result, it is highly possible to specify the reference data indicating a shake similar to the shake received by the target elevator. Therefore, the possibility that the target elevator can be temporarily restored increases.

(Modifications of Embodiments 1 and 2)
When the associating unit 104 and the associating unit 703 receive the information (inspection result) indicating the inspection result of the elevator 100 by the specialist while the diagnosis result is stored in the “inspection result” column of the reference data. , Both diagnostic and inspection results may be stored (ie, diagnostic results may remain). In this case, the associating unit 104 and the associating unit 703 are able to identify which information is the inspection result so that the inspection result can be correctly selected when the diagnosis result and the inspection result are different. For example, the association unit 104 and the association unit 703 associate the identification information with at least one of the diagnosis result and the inspection result. As a result, even when the diagnosis result and the inspection result are different, the diagnostic operation control unit 131 and the diagnostic operation determination unit 702 can accurately determine whether or not the execution of the automatic diagnostic provisional recovery operation is permitted. .. For example, when the diagnosis result is “no abnormality” and the inspection result is “abnormality”, the diagnostic operation control unit 131 and the diagnostic operation determination unit 702 determine that the execution of the automatic diagnostic provisional recovery operation is not permitted. be able to.

Further, when the diagnostic operation determination unit 702 determines that the inspection result data of the reference data is “abnormal”, it is determined that the elevator 200, which is the target elevator, does not execute the automatic diagnostic provisional recovery operation. It may be possible to output to the associating unit 703 whether or not the diagnostic operation is possible.

Further, when the shaking occurs a plurality of times in a short period of time, there is a possibility that information is not stored in the “inspection result” column of the reference data specified by the similar situation specifying unit 102 and the similar situation specifying unit 701. In this case, the diagnostic operation control unit 131 and the diagnostic operation determination unit 702 may determine whether to permit execution of the automatic diagnostic provisional recovery operation based on the information in the “automatic diagnostic operation” column of the reference data. .. Specifically, when the information indicating that the automatic diagnostic operation has been executed (“OK” shown in FIGS. 5 and 11) is stored in the “automatic diagnostic operation” column, the diagnostic operation control unit 131 and the diagnostic operation determination are performed. The unit 702 permits the execution of the automatic diagnosis temporary restoration operation. On the other hand, when the information indicating that the automatic diagnosis operation is not executed (“No” shown in FIGS. 5 and 11) is stored in the “automatic diagnosis operation” column, the diagnosis operation control unit 131 and the diagnosis operation determination unit 702 does not allow execution of the automatic diagnosis temporary recovery operation. Further, the diagnostic operation control unit 131 and the diagnostic operation determination unit 702 may be configured not to allow execution of the automatic diagnostic provisional recovery operation when information is not stored in the “inspection result” column of the reference data.

[Embodiment 3]
Still another embodiment of the present invention will be described below. For convenience of description, members having the same functions as the members described in the above embodiment will be designated by the same reference numerals, and the description thereof will be omitted.

FIG. 15 is a block diagram showing an example of the main configuration of the management server 7a according to this embodiment. As illustrated, unlike the management server 7 described in the second embodiment, the management server 7a includes a control unit 70a and a storage unit 72a instead of the control unit 70 and the storage unit 72. Unlike the storage unit 72, the storage unit 72a stores a reference data table 721a instead of the reference data table 721. Further, the storage unit 72a newly stores the driving permission score 722. The details of the reference data table 721 and the operation permission score 722 will be described later.

Unlike the control unit 70, the control unit 70a does not include the similar situation specifying unit 701. Further, the control unit 70a includes a diagnostic operation determination unit 702a (operation allowance unit) and an association unit 703a instead of the diagnostic operation determination unit 702 and the association unit 703. In addition, the control unit 70a newly includes a swing score calculation unit 704 (calculation unit) and a permission score update unit 705.

The swing point calculation unit 704 calculates the degree of damage to the target elevator based on the acquired data. For example, the sway score calculation unit 704 scores the sway magnitude, the elevator sway direction, the position of the car 23, and the presence or absence of movement of the car 23, which are included in the acquired data, and sums them to obtain a score indicating the degree of damage. (Hereinafter, it will be referred to as the “sway point”).

FIG. 16 is a diagram showing a specific example of calculation of the number of shaking points. The acquired data of the example shown in (a) of FIG. 16 shows that the shaking occurrence date and time is “July 24, 2017 9:51”, the shaking magnitude is “350 Gal”, and the shaking is shaking in the elevator 200A. Direction is “15°, the elevator sway direction is not the car-side guide rail direction”, the position of the car 23 when the sway occurs is “10th floor, within the non-resonance range”, and when the sway occurs This means that the movement of the car 23 is “none”. In the acquired data of the example illustrated in FIG. 16B, regarding the shaking generated in the elevator 200B, the shaking occurrence date and time is “July 24, 2017 9:51”, and the shaking magnitude is “350 Gal”. , The swaying direction is “85°, the elevator swaying direction is the car side guide rail direction”, the position of the car 23 when the swaying is “the first floor is within the resonance range”, and the swaying is This means that the movement of the car 23 is “present”. The details of the “car side guide rail direction” will be described later.

As illustrated, the swing score calculation unit 704 according to the present embodiment uses the value of the swing magnitude as it is as the score. In the case of the illustrated example, since the magnitude of the shaking is 350 Gal, the score of the shaking is 350.

Further, the swing score calculation unit 704 according to the present embodiment makes a predetermined determination for an event other than the magnitude of the swing, and determines the score based on the result of the determination. A typical example of the predetermined determination is (1) the elevator swaying direction is a direction in which the rope 24 sways in the direction of a guide rail (not shown) on the car 23 side of the elevator 200 (the “car side guide rail direction” described above). Whether or not (2) the position of the car 23 when the shaking occurs is within the resonance range, and (3) whether or not the car 23 is moving when the shaking occurs.

When the swaying direction of the elevator is in the car-side guide rail direction, there is a higher possibility that the rope 24 will come into contact with various switches (not shown) provided in the hoistway 21 and be damaged, as compared with the case where the rope-side guide rail direction is not set. Become. This is because, in a general elevator, various switches are arranged on a guide rail on the car side through a bracket (not shown). A position detection switch is mentioned as an example of various switches. The position detection switch is a switch used to match the position of the floor of the car 23 with each floor. If the switch is damaged, there is a risk that the floor of the car 23 and the floors of the car 23 are displaced when the car 23 stops at each floor. For this reason, the sway point calculation unit 704 raises the score when the elevator sway direction is the car side guide rail direction compared to when the elevator sway direction is not the car side guide rail direction. For example, as shown in the figure, the score is "20" when the elevator sway direction is the car-side guide rail direction, and the score is "5" when it is not the car-side guide rail direction. Whether or not the elevator sway direction is the car-side guide rail direction depends on whether or not the elevator sway direction (that is, the angle) is included in a predetermined numerical range (for example, 70° to 100°). Can be determined.

Further, when the position of the car 23 is within the resonance range, the rope 24 is highly likely to sway. In this case, the possibility that each member in the hoistway 21 is damaged by the contact of the rope 24 is higher than that in the case where the position of the car 23 is within the non-resonance range. Therefore, the swing point calculation unit 704 increases the score when the position of the car 23 is within the resonance range as compared with when the position of the car 23 is within the non-resonance range. For example, as shown in the figure, the score when the position of the car 23 is on the resonance floor is “20”, and the score when it is on the non-resonance floor is “0”.

Further, when the car 23 is moving when the shaking occurs, there is a high possibility that the car 23 is derailed as compared with the case where the car 23 is not moving. Therefore, the sway score calculation unit 704 raises the score when the car 23 is moving when the sway is generated, compared to when the car 23 is not moving. For example, as shown in the figure, the score when the car 23 is moving when a shake occurs is set to "10", and the score when it is not moving is set to "5".

As a result, the number of swing points is 360 in the case of the acquired data shown in FIG. 16(a) and 400 in the case of the acquired data shown in FIG. 16(b). The shaking point number calculation unit 704 associates the calculated shaking point number with the elevator identification information included in the acquired data, and outputs it to the diagnostic operation determination unit 702a. Further, the shaking point number calculating unit 704 outputs the received acquisition data and the calculated shaking point number to the associating unit 704a.

The control unit 70a will be described with reference to FIG. 15 again. The diagnostic operation determination unit 702a determines whether to permit execution of the automatic diagnostic provisional recovery operation of the target elevator, as with the diagnostic operation determination unit 702. Specifically, when the diagnostic driving determination unit 702a acquires the shaking score, it reads the driving permission score 722 from the storage unit 72a, determines whether the acquired shaking score is equal to or less than the driving permission score 722, and the determination result Send notification to elevator 200.

Here, the driving permission score 722 will be described. The operation permission score 722 is a threshold value calculated based on the shake data and the event data included in the reference data including the inspection result data indicating that the elevator 200 has no abnormality. Although the method of calculating the driving permission score 722 is not limited to a particular one, in the present embodiment, the driving permission score 722 is calculated by the shaking point calculation unit 704 when the shaking data and the event data included in the reference data are received as the acquired data. It is the average value of the calculated shaking points.

When it is determined that the swing point is equal to or less than the operation permission point 722, the diagnostic operation determination unit 702a permits execution of the automatic diagnostic provisional recovery operation. Then, the diagnostic operation determination unit 702 transmits the diagnostic operation permission notification to the elevator indicated by the elevator identification information acquired together with the reference data via the communication unit 71. On the other hand, when it is determined that the shaking score is greater than the driving permission score 722, the diagnostic driving determination unit 702a does not allow execution of the automatic diagnostic temporary restoration driving. Then, the diagnostic operation determination unit 702 transmits the diagnostic operation disapproval notification to the elevator indicated by the elevator identification information acquired together with the reference data via the communication unit 71.

For example, when the driving permission score 722 is “380” and the diagnostic driving determination unit 702a acquires the shaking score shown in (a) of FIG. 16, the shaking score “360” is equal to or less than “380”. The diagnostic operation determination unit 702a permits execution of the automatic diagnostic provisional recovery operation, and transmits a diagnostic operation permission notification to the elevator 200A. On the other hand, when the driving permission score 722 is “380” and the diagnostic driving determination unit 702a acquires the shaking score shown in (b) of FIG. 16, the shaking score “400” is larger than “380”. The diagnostic operation determination unit 702a does not allow execution of the automatic diagnostic provisional recovery operation, and transmits a diagnostic operation non-permission notice to the elevator 200B.

Similarly to the associating unit 703, the associating unit 703a generates reference data based on the shaking generated in the elevator 200, and updates the reference data table 721. The different point of the associating unit 703a from the associating unit 703 is that first, reference data including the acquired shaking point number is generated. That is, the reference data table 721a according to the present embodiment includes a column that stores the number of swing points. Furthermore, the associating unit 703a transmits the update instruction of the operation permission score 722 to the permission score updating unit 705 when the reference data including the inspection result data indicating that the elevator 200 has no abnormality is generated. Different from 703.

The permission score updating unit 705 updates the driving permission score 722. Specifically, when the permission point updating unit 705 receives an instruction from the associating unit 703a, the reference data table 721a includes reference data including inspection result data indicating that the elevator 200 has no abnormality, that is, “inspection result”. Read out the number of swing points of the reference data for which "No error" is stored in the column. Then, the permitted score updating unit 705 adds all the read swing points, and divides the value after the addition by the number of read swing points. Thereby, the permission score updating unit 705 can calculate the driving permission score 722 in consideration of the swing score in the newly generated reference data. Then, the permission score updating unit 705 updates the driving permission score 722 to the calculated score.

(Flow of processing executed by the management server 7a)
FIG. 17 is a flowchart showing an example of the flow of the diagnostic operation determination process executed by the management server 7a. Note that, in FIG. 17, steps showing the same processing as in FIG. 13 are given the same step numbers as in FIG. Further, the description of the steps showing the same processing as in FIG. 13 will be omitted here.

When the acquired data is received in step S61, the shaking score calculation unit 704 calculates the shaking score based on the acquired data (S82). The shaking point number calculation unit 704 associates the calculated shaking point number with the elevator identification information included in the acquired data, and outputs it to the diagnostic operation determination unit 702a. Further, the shaking point number calculating unit 704 outputs the acquired data and the shaking point number to the associating unit 703a.

When the diagnostic driving determination unit 702a acquires the shaking score, the diagnostic driving determination unit 702a reads the driving permission score 722 from the storage unit 72a and determines whether the acquired shaking score is equal to or less than the driving permission score 722 (S83). When it is determined that the acquired shaking score is equal to or less than the driving permission score 722 (YES in S83), the diagnostic driving determination unit 702a executes the process of step S64. On the other hand, when it is determined that the acquired shaking score is not equal to or less than the driving permission score 722 (NO in S83), the diagnostic driving determination unit 702a executes the process of step S65.

FIG. 18 is a flowchart showing an example of the flow of reference data generation processing executed by the management server 7a. In FIG. 18, steps showing the same processing as in FIG. 14 are given the same step numbers as in FIG. Further, description of steps showing the same processing as in FIG. 14 will be omitted here.

Upon reception of the diagnostic driving availability in step S71, the associating unit 703a stores the received diagnostic driving availability, the acquired acquired data and the number of swing points as reference data (S91).

When the information is stored in the “inspection result” column in the reference data, the associating unit 703a determines whether the information is “no abnormality” indicating that the elevator 200 has no abnormality (S92). ). In the case of "no abnormality", the associating unit 703a transmits an instruction to update the driving permission score 722 to the permission score updating unit 705. The permission score updating unit 705 updates the driving permission score 722 according to the instruction of the associating unit 703a (S93).

As described above, in the management server 7a according to the present embodiment, when the swing score calculated based on the acquired data is equal to or less than the operation permission score 722 based on the reference data including the inspection result data indicating that the elevator 200 has no abnormality. , Allow execution of automatic diagnosis temporary recovery operation. As a result, whether or not to permit the execution of the automatic diagnosis temporary restoration operation is determined based on not all the reference data similar to the acquired data but all the reference data including the inspection result data indicating that the elevator 200 has no abnormality. Can be determined. Therefore, it is possible to more accurately determine whether or not to permit execution of the automatic diagnosis provisional recovery operation.

(Modification of Embodiment 3)
The operation permission score 722 may be a score calculated using only reference data whose inspection result by the specialist engineer is “no abnormality”. In other words, the permission score updating unit 705 does not use the reference data whose diagnosis result of the automatic diagnosis operation is “no abnormality” for updating the permission score. This makes it possible to more accurately determine whether or not to permit execution of the automatic diagnosis temporary recovery operation. In the case of this example, the associating unit 703a outputs an instruction to update the operation permission score 722 to the permission score updating unit 705 when “no abnormality” is stored as the inspection result in the generated reference data. In addition, when the permission score updating unit 705 receives the update instruction, the permission score updating unit 705 reads the shaking score included in the reference data in which “no abnormality” is stored as the inspection result, and updates the operation permission score 722. In the case of this example, the information stored in the "inspection result" column is information that can identify whether it is an inspection result or a diagnosis result. For example, the associating unit 703a associates identification information with at least one of the diagnosis result and the inspection result.

The sway score calculation unit 704 may use the acquired data to reproduce the sway generated in the target elevator to estimate the damage level of the target elevator, and score the damage level. That is, the swing score calculation unit 704 may be a so-called simulator. When the shake point number calculation unit 704 according to the present modification receives the acquired data, it searches the layout table (not shown) using the elevator identification information associated with the acquired data, and associates it with the elevator identification information. Read the layout information. The swing score calculation unit 704 virtually generates the elevator 200 in which the swing has occurred in the management server 7a using the read layout information. Further, the shaking point number calculation unit 704 includes the position of the car 23 at the time of shaking, the presence/absence of movement of the car 23 at the time of shaking, and the moving direction (only when moving) included in the acquired data. By using the virtual elevator 200, the state of the car 23 of the elevator 200 at the time when the shaking occurs is reproduced. That is, the acquired data according to the present modification further includes the moving direction of the car 23 only when the car 23 is moving. Further, the swing point number calculation unit 704 reproduces the swing of the elevator 200 in the virtually generated elevator 200 by using the swing direction and the magnitude of the elevator 200 included in the acquired data. As a result, the swing point number calculation unit 704 can reproduce the swing of the elevator 200 and the damage that is expected to occur in the elevator 200 due to the reproduced swing.

The layout table is data that stores the layout information 121 of each elevator 200 in association with the elevator identification information.

The shaking score calculation unit 704 calculates the shaking score by scoring the degree of the damage based on a predetermined standard. In this modification, an example of calculating the number of swing points in the range of 0 to 100 will be described, but the range of the number of swing points is not limited to this example. Specifically, the shaking point number calculation unit 704 sets the criteria set for each item such as the amount of damage, the severity of the damage, the magnitude of the effect on restarting the operation, the difficulty of repair, etc., for the damage that has occurred. The shaking score is calculated with reference. In this example, since the number of items is four, damage may be scored with an upper limit of 25 points for each item, and the four scores may be summed to calculate the swing score. Note that the types and numbers of the above items and the method of calculating the number of swing points are examples, and the present invention is not limited to this example. Further, the reference for calculating the number of swing points may be stored in advance in the storage unit 72a (not shown in FIG. 15).

The management server 7a and the simulator may be separate devices. In the case of this example, the swing point calculation unit 704 transmits the received acquired data to the simulator via the communication unit 71, and reproduces the damage that is expected to occur in the elevator 200. The swing score calculation unit 704 acquires information indicating the damage from the simulator, and calculates the swing score by, for example, the method described above.

Further, the diagnostic operation determination unit 702a indicates whether or not the acquired number of shaking points is equal to or less than the driving permission point 722, and indicates in the reference data table 721 a shaking amount equal to or greater than the shaking amount included in the acquired data, and It may be configured to determine whether or not there is reference data including inspection result data indicating that the elevator 200 has no abnormality. The diagnostic operation determination unit 702a according to the present modification allows execution of the automatic diagnostic provisional recovery operation when the acquired number of swing points is equal to or less than the operation permission point 722 and the reference data as described above exists. That is, in the present modification, the number of swing points is equal to or less than the operation permission point 722, and the presence of the reference data as described above in the reference data table 721 requires the execution of the automatic diagnosis temporary recovery operation. It is a condition.

[Modifications common to each embodiment]
Hereinafter, a case where a modification common to each embodiment is applied to the first embodiment will be described. The modified examples described below are also applicable to the second and third embodiments.

The control panel 1 may determine whether or not to permit the execution of the automatic diagnostic provisional recovery operation based on the acquired shake data and the shake data and the inspection result data included in the reference data. Specifically, the diagnostic operation control unit 131 indicates, in the reference data table 123, a check result data indicating that the reference data table 123 indicates a shake that is equal to or larger than the shake indicated by the shake data acquired as the acquired data, and that the elevator 100 has no abnormality. It is determined whether or not there is reference data including. Then, when such reference data exists, the diagnostic operation control unit 131 permits the execution of the automatic diagnostic provisional recovery operation. On the other hand, if such reference data does not exist, execution of the automatic diagnosis temporary restoration operation is not permitted. In addition, in the case of this modification, the acquired data may include only the shake data. Further, the reference data may include only shaking data and inspection result data.

Further, the control panel 1 generates the acquired data and generates the reference data from the acquired data even when the operation signal is acquired only from the P wave sensor and the low setting sensor, and the reference data table is generated. The configuration may be such that it is stored in 123.

Specifically, the data acquisition unit 101 acquires the shake data and the event data when at least the operation signal is acquired from the P wave sensor and the low setting sensor, and generates the acquired data. Further, when the associating unit 104 acquires the acquired data, the associating unit 104 generates reference data and stores it in the reference data table 123.

When the operation signals are obtained only from the P wave sensor and the low setting sensor, the diagnostic operation control unit 131 starts the automatic diagnostic operation if other conditions are satisfied. Therefore, when the data acquisition unit 101 acquires the operation signal from only the P wave sensor and the low setting sensor to generate the acquired data, the data acquisition unit 101 does not output the acquired data to the similar situation specifying unit 102, and the association unit It may be output to 104. In other words, when the control panel 1 acquires the operation data from only the P wave sensor and the low setting sensor to generate the acquired data, the control panel 1 specifies the reference data indicating the shaking similar to the shaking received by the target elevator, Further, the configuration may be such that it is not determined whether or not the execution of the automatic diagnosis temporary restoration operation is permitted.

Further, when the configuration of the preceding paragraph is applied to the second and third embodiments, the operation data is acquired from only the P wave sensor and the low setting sensor in the acquisition data transmitted by the elevator 200 to the management server 7 or the management server 7a. It is sufficient to add information indicating that. As a result, whether the management server 7 or the management server 7a permits the reference data indicating the shake similar to the shake received by the target elevator and the execution of the automatic diagnosis temporary recovery operation in the received acquisition data. It is possible to specify whether or not to make the determination.
