Description

Elevator control device

The present invention relates to an elevator control device that travels to a predetermined evacuation position after an emergency stop of an elevator car.

Conventional elevators are controlled so that the car is fired on the floor in a range where the car does not pass the weight when the car is stopped on the predetermined floor by the earthquake operation and the rescue operation is performed in the fire. Yes. For example, if the car stops urgently in the upper part of the building, an evacuation position is set on the upper part side, and only registration of calls on the upper floor is permitted. On the other hand, when the car stops in an emergency at the lower part of the building, an evacuation position is set on the lower side and only registration of calls on the lower floor is permitted. According to such an elevator, it is possible to reliably prevent the car and the weight from colliding with each other. For this reason, those who are left behind in the building where the elevator is installed can evacuate safely using the elevator (see, for example, Patent Document 1).

DETAILED DESCRIPTION Embodiments for carrying out the present invention will be described with reference to the accompanying drawings. In addition, in each figure, the same code | symbol is attached | subjected to the part which is the same or it corresponds, The duplication description is simplified or abbreviate | omitted suitably.

Embodiment 1 FIG.
1 is a block diagram of an elevator control apparatus according to Embodiment 1 of the present invention.
Reference numeral 1 denotes an elevator driving motor. The elevator driving motor 1 has a function of supplying a driving force for raising and lowering an elevator car (not shown in FIG. 1) and a weight (not shown in FIG. 1) in opposite directions.

2 is an earthquake sensor. The earthquake sensor 2 is provided in an elevator hoistway (not shown) or the like. This earthquake sensor 2 functions as a disaster detection means for detecting a disaster to the elevator. In other words, the earthquake sensor 2 has a function of sensing the shaking of the building where the elevator is set.

3 is an elevator control means. The elevator control means 3 is composed of an elevator machine room (not shown) and a control panel provided in a hoistway. The elevator control means 3 includes an elevator operation control means 4, a speed command control means 5, a speed detection means 6, a car position detection means 7, and a control operation time management means 8.

The elevator operation control means 4 has a function of managing and controlling the operation of the elevator. The speed command control means 5 has a function of controlling the rotational speed of the elevator driving motor 1 based on a command from the elevator operation control means 4. The speed detection means 6 has a function of detecting the actual speed of the elevator driving motor 1.

The car position detecting means 7 has a function of automatically detecting the position of the car based on the actual speed of the elevator driving motor 1 detected by the speed detecting means 6. The control operation time management means 8 has a function of managing the time until transition to the control operation based on a command from the elevator operation control means 4.

In the elevator control device having such a configuration, when the seismic sensor 2 senses a shake of the building while the car is traveling normally, the elevator operation control means 4 causes the speed command control means 5 to stop the car urgently. Command to output. The speed command control means 5 to which such a command is input outputs a stop command to the elevator driving motor 1. The elevator driving motor 1 to which such a command is input starts to decelerate.

At this time, the actual speed of the elevator driving motor 1 detected by the speed detection means 6 is fed back to the speed command control means 5. Then, the speed command control means 5 controls the speed of the elevator driving motor 1 by outputting an optimum speed command based on the feedback detection value.

Further, the control operation time management means 8 starts counting the time until automatic return to the control operation, triggered by the transition to the emergency stop control by the elevator operation control means 4. And if the time until it transfers to control operation passes, the elevator operation control means 4 will output the instruction | command so that it may transfer to control operation with respect to the speed command control means 5.

The speed command control means 5 to which such a command is input outputs a command to the elevator drive motor 1 so that the car travels to the evacuation position determined based on the car emergency stop position detected by the car position detection means 7. To do. The elevator driving motor 1 to which the command is input drives the car to travel to the evacuation position. With this driving, the car arrives at the evacuation position. A user in the car can evacuate from the evacuation position to the outside of the car.

In the present embodiment, as a mode for determining the evacuation position, a mode according to the situation can be set from the safety priority mode and the travel time reduction mode. These modes can be switched by operating a switch or the like. Hereinafter, the control operation in the present embodiment will be described.

First, the case where the safety priority mode is set will be described with reference to FIGS. 2 and 3.
FIG. 2 is a side view of the elevator for explaining a case where the safety priority mode is set in the elevator control apparatus according to Embodiment 1 of the present invention.

In FIG. 2, 9 is a sheave. The sheave 9 is attached to the rotating shaft of the elevator driving motor 1. A main rope 10 is wound around the sheave 9. A car 11 is connected to one end of the main rope 10. A weight 12 is connected to the other end of the main rope 10.

Also, 13 is the nearest floor. This nearest floor 13 is the floor closest to the emergency stop position of the car 11 among the evacuation floors that can stop the car 11 during the control operation. 14 is a floor directly below. 15 is an upper refuge floor. The upper evacuation floor 15 is an evacuation floor disposed on the α floor above the nearest floor 13.

16 is the driving direction. This driving direction 16 is a traveling direction when the car 11 resumes driving after an emergency stop. As shown in FIG. 2, in the safety priority mode, when the car 11 makes an emergency stop immediately above the nearest floor 13, the car 11 resumes traveling toward the upper evacuation floor 15 in the driving direction 16 away from the weight 12. .

FIG. 3 is a side view of the elevator for explaining the case where the safety priority mode is set in the elevator control apparatus according to Embodiment 1 of the present invention.
In FIG. 3, 17 is the nearest floor. The nearest floor 17 corresponds to the n + α floor. 18 is an exit. In FIG. 3, the exit 18 is provided at a height corresponding to the n + β floor. However, the exit 18 may be provided between adjacent floors. The exit 18 is provided to rescue the user in the car 11 from other than the elevator entrance. For example, the exit 18 is provided in a hoistway facing the car 11. Reference numeral 19 denotes a driving direction. As shown in FIG. 3, when the car 11 stops just above the exit 18, the car 11 resumes traveling toward the nearest floor 17 in the driving direction 19 away from the weight 12.

Thus, in the safety priority mode, the car 11 resumes traveling in the driving direction 19 or the like away from the weight 12. For this reason, it can prevent reliably that the cage | basket | car 11 and the weight 12 collide. That is, the user confined in the car 11 can be rescued safely. However, if the distance to the evacuation position such as the upper evacuation floor 15 or the nearest floor 17 is long, it takes a long time for the car 11 to move to the evacuation position, and anxiety is raised for the users in the car 11. .

In contrast, in the travel time reduction mode, the time required for the car 11 to move to the evacuation position can be shortened. Hereinafter, the travel time reduction mode of the elevator control device of the present embodiment will be described in detail.

First, the height direction positions of the floors where the elevators are installed and the exit 18 will be described with reference to FIG.
FIG. 4 is a diagram for explaining floor position information stored in the elevator control apparatus according to Embodiment 1 of the present invention.

In FIG. 4, 20 is a memory. This memory 20 is provided in the elevator control means 3. The memory 20 is composed of an E2PROM or the like that can rewrite information and stores the stored information even after the power is turned off. The memory 20 stores a floor position information table in the height direction between each floor where the elevator is installed and the exit 18.

Here, the floor position information of each floor is the position information when the car 11 arrives at a position where the user can get on and off using the elevator doorway. The floor position information of the exit 18 is position information when the car 11 arrives at a position where the user in the car 11 can be rescued from other than the elevator entrance.

In FIG. 4, the height difference between each floor and the reference floor is stored in advance as the floor position information. However, there is a case where the elevator is in a learning operation to detect floor position information and store it in the memory 20. In this case, based on the actual speed of the elevator driving motor 1 detected by the speed detection means 6, the value detected by the car position detection means 7 is stored in the memory 20 as floor position information.

Next, the concept of floor information indicating the floor number corresponding to the current position of the car 11 will be described with reference to FIGS. 5 and 6.
FIG. 5 is a diagram for explaining the concept of the floor information of the elevator control apparatus according to Embodiment 1 of the present invention. FIG. 6 is a flowchart for explaining the operation of the elevator control apparatus according to Embodiment 1 of the present invention for storing the floor information.

As shown in FIG. 5, when the car 11 is located between the center position of the specific floor (n floor) and the upper adjacent floor to the specific floor, the lower adjacent floor and the central position, the current position of the car 11 is specified. It is supposed to be a floor. For example, when the car 11 is located above the center position of the first floor and the second floor and below the center position of the second floor and the third floor, the current position of the car 11 is determined as “second floor”. The Specifically, as shown in step S <b> 1 of FIG. 6, the floor information of the current position of the car 11 is stored in the memory 20 in accordance with the determination criteria of FIG. 5.

Next, the operation of the elevator set in the travel time reduction mode will be described with reference to FIG.
FIG. 7 is a flowchart for explaining the operation of the elevator using the elevator control apparatus according to Embodiment 1 of the present invention.

First, in step S11, the emergency stop position of the car 11 measured by the car position detecting means 7 is stored in the memory 20 as a variable (A), and the process proceeds to step S12. In step S12, the floor information acquired in step S1 of FIG. 6 is stored in the memory 20 as the variable (B) based on the variable (A), and the process proceeds to step S13.

In step S13, the regular floor position information of the variable (B) related to the floor information acquired in step S11 is acquired from the floor position information table and then stored in the memory 20 as the variable (C), and the process proceeds to step S14. . In step S14, the floor position information of the exit 18 is acquired from the floor position information table and then stored in the memory 20 as a variable (D), and the process proceeds to step S15.

In step S15, after the distance from the emergency stop position of the car 11 to the nearest floor 17 is measured, it is stored in the memory 20 as a variable (E), and the process proceeds to step S16. In step S16, after the distance from the emergency stop position of the car 11 to the exit 18 is measured, it is stored in the memory 20 as a variable (F), and the process proceeds to step S17.

In step S17, it is determined which is closer to the nearest floor 17 or the exit 18 from the emergency stop position of the car 11. Specifically, it is determined whether or not the variable (E) is greater than or equal to the variable (F). If the nearest floor 17 is closer to the exit 18 and the variable (E) is less than the variable (F), the process proceeds to step S18. In step S18, the car 11 is restarted in the direction where the nearest floor 17 is located, and the process proceeds to step S19.

In step S19, it is determined whether or not the variable (A) is greater than or equal to the variable (C) in order to determine in which direction the nearest floor 17 is located with respect to the emergency stop position of the car 11. If the variable (A) is greater than or equal to the variable (C), the process proceeds to step S20. In step S20, the car 11 is activated in the DN direction, and the operation ends. On the other hand, if the variable (A) is less than the variable (C) in step S19, the process proceeds to step S21. In step S21, the car 11 is activated in the UP direction, and the operation ends.

On the other hand, if the exit 18 is closer than the nearest floor 17 in step S17 and the variable (E) is equal to or greater than the variable (F), the process proceeds to step S22. In step S22, the car 11 is restarted in the direction where the exit 18 is located, and the process proceeds to step S23. In step S23, it is determined whether or not the variable (A) is equal to or greater than the variable (D) in order to determine in which direction the exit 18 is located with respect to the emergency stop position of the car 11. When the variable (A) is greater than or equal to the variable (D), the process proceeds to step S20, the car 11 is activated in the DN direction, and the operation is finished. On the other hand, when the variable (A) is less than the variable (D), the process proceeds to step S21, the car 11 is activated in the UP direction, and the operation ends.

Next, the specific operation of the car 11 when the time reduction mode that is the flow of FIG. 7 is set will be described with reference to FIGS.
FIG. 8 is a side view of the elevator for explaining a first specific example of the operation of the elevator in which the elevator control apparatus according to Embodiment 1 of the present invention is used.

In FIG. 8, 21 is an intermediate position h. The intermediate position h21 is a position where the car 11 and the weight 12 pass each other when the car 11 and the weight 12 are moved up and down. As shown in FIG. 8, the emergency stop position of the car 11 is closer to the exit 18 than the nearest floor 17. In this case, the elevator operation proceeds from step S17 in FIG. 7 to step S22, and then proceeds to step S23.

Then, the car 11 is urgently stopped above the intermediate position h21 and above the exit 18. In this case, the process proceeds from step S23 in FIG. 7 to step S20, and the car 11 travels in the DN direction. That is, the car 11 travels in the driving direction 22 that passes the weight 12.

In particular, when the emergency stop position of the car 11 is above the intermediate position h21 and the exit 18 is below the intermediate position h21, the car 11 actually passes the weight 12 and travels down to the exit 18. .

On the other hand, in FIG. 8, when the emergency stop position of the car 11 is below the exit 18, the process proceeds from step S <b> 23 to step S <b> 21 in FIG. 7, and the car 11 travels in the UP direction. That is, the car 11 travels upward in a direction away from the weight 12.

FIG. 9 is a side view of the elevator for explaining a second specific example of the operation of the elevator in which the elevator control device according to Embodiment 1 of the present invention is used.
As shown in FIG. 9, the emergency stop position of the car 11 is closer to the nearest floor 17 than the exit 18. In this case, the elevator operation proceeds from step S17 in FIG. 7 to step S18, and then proceeds to step S19.

And the car 11 is stopped emergencyly above the intermediate position h21 and below the nearest floor 17. In this case, the process proceeds from step S19 in FIG. 7 to step S21, and the car 11 travels in the UP direction. That is, the car 11 travels in the driving direction 23 away from the weight 12.

On the other hand, in FIG. 9, when the emergency stop position of the car 11 is above the nearest floor 17, the process proceeds from step S19 to step S20 in FIG. 7, and the car 11 travels in the DN direction. That is, the car 11 travels downward in a direction passing the weight 12.

In particular, when the emergency stop position of the car 11 is above the intermediate position h21 and the nearest floor 17 is below the intermediate position h21, the car 11 actually passes the weight 12 and descends to the nearest floor 17. Run.

FIG. 10 is a side view of the elevator for explaining a third specific example of the operation of the elevator using the elevator according to the first embodiment of the present invention.
In FIG. 10, 24 is an escape port. The exit 24 is provided at a height corresponding to the n-β floor. 25 is the nearest floor. This nearest floor 25 corresponds to the n-α floor. As shown in FIG. 10, the emergency stop position of the car 11 is closer to the nearest floor 25 than the exit 24. In this case, the elevator operation proceeds from step S17 in FIG. 7 to step S18, and then proceeds to step S19.

Then, the car 11 is urgently stopped below the intermediate position h21 and below the nearest floor 25. In this case, the process proceeds from step S19 in FIG. 7 to step S21, and the car 11 travels in the UP direction. That is, the car 11 travels in the driving direction 26 that passes the weight 12.

In particular, when the emergency stop position of the car 11 is below the intermediate position h21 and the nearest floor 25 is above the intermediate position h21, the car 11 actually passes the weight 12 and rises to the nearest floor 25. Run.

On the other hand, in FIG. 10, when the emergency stop position of the car 11 is above the nearest floor 25, the process proceeds from step S19 to step S20 in FIG. 7, and the car 11 travels in the DN direction. That is, the car 11 travels downward in a direction away from the weight 12.

According to the first embodiment described above, in the travel time reduction mode, the car 11 travels to the evacuation position near the emergency stop of the car 11 regardless of the emergency stop position of the car 11. That is, when an earthquake occurs, the emergency stop position of the car 11 is one above or below the intermediate position where the car 11 and the weight 12 pass each other, and the evacuation position near the emergency stop position of the car 11 is higher than the intermediate position. Even in the case of the other of the upper side and the lower side, the car 11 is caused to pass the weight 12 and travel to the evacuation position.

Therefore, the car 11 travels to the evacuation position where the distance from the emergency stop position of the car 11 is the shortest. That is, in the travel time reduction mode, the time required for the car 11 to move to the evacuation position can be shortened compared to the safety priority mode.

Embodiment 2. FIG.
FIG. 11 is a flowchart for explaining the operation of the elevator using the elevator control apparatus according to Embodiment 2 of the present invention. In addition, the same code | symbol is attached | subjected to the part which is the same as that of Embodiment 1, or an equivalent, and description is abbreviate | omitted.

In Embodiment 1, it was not considered that a fire occurred near the evacuation position. On the other hand, in the second embodiment, it is considered that a fire has occurred near the evacuation position. Specifically, in the second embodiment, in addition to the earthquake sensor 2, a fire sensor (not shown) is also provided as a disaster detection means. This fire sensor is provided on each floor corresponding to the elevator hall. This fire sensor has a function of detecting a fire in the vicinity of each floor landing, the exit 18 and the like.

The operation of the present embodiment is the same as that of the first embodiment up to step S17. If the variable (E) is less than the variable in step S17, the process proceeds to step S18. In step S18, the car 11 is restarted in the direction where there is one end, the nearest floor 17 and the like, and the process proceeds to step S31. In step S31, based on the fire detection result by the fire sensor, it is determined whether or not the nearest floor 17 or the like cannot be stopped by a fire. If no fire has occurred on the nearest floor 17 and the car 11 can be stopped, the process proceeds to step S19, and then the same operation as in the first embodiment is performed.

On the other hand, if a fire has occurred on the nearest floor 17 and the car 11 cannot be stopped, the process proceeds to step S32. In step S32, the car 11 is restarted in the direction in which the exit 18 is located, and the process proceeds to step S33. In step S33, the speed of the car 11 is set to a value that is higher by α than the speed during normal evacuation. Thereafter, after proceeding to step S23, the same operation as in the first embodiment is performed.

On the other hand, if the variable (E) is greater than or equal to the variable (F) in step S17, the process proceeds to step S22. In step S22, the car 11 is restarted in a direction where there is one end, the exit 18 and the like, and the process proceeds to step S34. In step S34, based on the fire detection result by the fire sensor, it is determined whether or not the exit 18 and the like cannot be stopped by a fire. If no fire has occurred at the exit 18 or the like and the car 11 can be stopped, the process proceeds to step S23, and then the same operation as in the first embodiment is performed.

On the other hand, if a fire has occurred in the exit 18 and the car 11 cannot be stopped, the process proceeds to step S35. In step S35, the car 11 is restarted in the direction where the nearest floor 17 is located, and the process proceeds to step S36. In step S36, the speed of the car 11 is set to a value that is faster than the speed during normal evacuation by β. Thereafter, after proceeding to step S19, the same operation as in the first embodiment is performed.

According to the second embodiment described above, when a fire is detected at an evacuation position near the emergency stop position of the car 11 when the car 11 is emergency stopped when an earthquake is detected, The car 11 travels to another evacuation position in a direction opposite to the evacuation position near the emergency stop position of the car 11 at a speed higher than the speed at the time of normal evacuation. For this reason, although the distance to an evacuation position becomes long, it can shorten the time taken for the cage | basket | car 11 to move to an evacuation position, avoiding the influence of a fire.

Embodiment 3 FIG.
FIG. 12 is a flow chart for explaining the operation of the elevator using the elevator control apparatus in Embodiment 3 of the present invention. In addition, the same code | symbol is attached | subjected to the part which is the same as that of Embodiment 1, or an equivalent, and description is abbreviate | omitted.

In Embodiment 1, the speed when the car 11 and the weight 12 pass each other is not considered. On the other hand, in the third embodiment, consideration is given to the speed at which the car 11 and the weight 12 pass each other. Hereinafter, operation | movement of the elevator control means 3 of Embodiment 3 is demonstrated using FIG.

The operation of the present embodiment is obtained by adding an operation related to speed adjustment after the operation of the first embodiment. Specifically, after the car 11 is activated in the DN direction in step S20, the process proceeds to step S41. In step S41, it is determined whether the variable (A) is equal to or greater than the center position h21. When the variable (A) is not less than the center position h21, the process proceeds to step S42. In step S42, a flag indicating that "the car 11 has passed the weight 12" is set, and the process proceeds to step S43.

In step S43, it is determined whether or not a flag indicating that "the car 11 passes the weight 12" is being set. Since the “car 11 passes the weight 12” flag is set first, the process proceeds to step S44. In step S44, the speed of the car 11 is set to a value that is slower by γ than the speed during normal evacuation, and the operation ends.

On the other hand, if the variable (A) is smaller than the central position h in step S41, the process proceeds to step S45. In step S45, the flag indicating that “the car 11 has passed the weight 12” is cleared, and the process proceeds to step S43. In this case, since the flag indicating that “the car 11 passes the weight 12” has been reset, the operation ends without reducing the speed of the car 11 in step S44.

Further, after the car 11 is activated in the UP direction in step S21, the process proceeds to step S46. In step S46, it is determined whether or not the center position h21 is greater than or equal to the variable (A). If the central position h21 is greater than or equal to the variable (A), the process proceeds to step S42, where the above-described operation is performed, the speed of the car 11 is set to a value slower by γ than the speed during normal evacuation, and the operation ends. To do. On the other hand, when the central position h21 is smaller than the variable (A) in step S46, the process proceeds to step S45, where the above-described operation is performed, and the operation ends without reducing the speed of the car 11.

According to the third embodiment described above, when the car 11 passes the weight 12 and travels to the evacuation position, the speed of the car 11 is made slower than the speed during normal evacuation. For this reason, even when the weight 12 is detached from the guide rail (not shown) due to an earthquake or the like, the horizontal swing of the weight 12 can be minimized. That is, the car 11 can be moved to the evacuation position while preventing the weight 12 that has come off the guide rail from colliding with the car 11.

In the first to third embodiments, the case has been described in which an earthquake is detected by the earthquake sensor 2 and the car 11 is restarted after an emergency stop between the floors. However, even if the disaster detection means such as a fire sensor or a submersion sensor detects a disaster to the elevator and the car 11 is suddenly stopped between the floors, it is restarted. As with, the elevator can be controlled.

As described above, according to the elevator control device of the present invention, the elevator car can be used for an elevator that travels to a predetermined evacuation position after an emergency stop of the elevator car.
