(Background of the present invention)
In order to appropriately perform group management control of a plurality of elevators, it is necessary to obtain a predicted waiting time in each direction of each floor of each elevator. In the case of a variable speed elevator, it is necessary to obtain a predicted waiting time in consideration of a section where the speed is increased and a section where the speed is not increased. Patent Document 1 discloses a technique for obtaining an expected arrival time (predicted waiting time) of each variable-speed elevator to each floor by calculation based on a moving distance, speed, acceleration, and the like. However, since the calculated value obtained by calculation based on the speed, acceleration, etc. is a theoretical value, it may be different from the waiting time at the actual site. Then, this invention makes it the subject to provide the group management system of the elevator which can obtain | require the prediction waiting time with higher precision.

  In the field, the frequency of speedup traveling is less than the frequency of normal traveling, and there is a bias in the section where the speed is increased. For example, when traveling from the lobby floor, the speed is often increased, but when departing from other floors, the speed is often not increased. In this invention, it is set as the further subject to provide the group management system of the elevator which can obtain | require prediction waiting time efficiently also in such a biased operation condition.

(Embodiment 1)
1. Configuration 1-1. Overview of Elevator Group Management System An overview of an elevator group management system according to the present embodiment will be described. FIG. 1 is a block diagram illustrating a configuration of an elevator group management system according to the first embodiment.

  The elevator group management system integrally controls the traveling and operation of a plurality of elevators 40A to 40F (No. A to No. F, hereinafter referred to as “No. machine” as appropriate). In the present embodiment, as an example, six elevators 40A to 40F from No. A to No. F are provided. Hereinafter, the elevators 40A to 40F may be referred to as “elevators 40” without being distinguished from each other.

  The elevator group management system includes a group management control device 10, a plurality of destination floor registration devices 20, and elevator control devices 30A to 30F. Hereinafter, the elevator control devices 30A to 30F may be referred to as “elevator control device 30” without being distinguished from each other.

  The elevator group management system adopts a destination floor registration system. In the present embodiment, the destination floor registration device 20 is provided at the landing on each floor or in the vicinity of the landing. The user performs a predetermined registration operation on the destination floor registration device 20 in order to designate a desired destination floor. This system assigns the registered destination floor to any elevator 40 of elevators 40A to 40F of No. A to No. F, and assigns the assigned elevator information indicating the assigned elevator 40 (assigned car) to the destination floor registration device 20.

  The elevator control device 30 of each elevator 40 controls the operation of the hoisting machine and the like based on the control signal from the group management control device 10, thereby controlling the raising, lowering, stopping, traveling speed, and the like of the car. In the present embodiment, each elevator 40 is a variable speed elevator. A variable speed elevator is an elevator that can travel at a traveling speed faster than the rated speed if the weight difference between the car (including the user (passenger)) and the counterweight is small and the traveling distance is a predetermined distance or more. It is. The rated speed is the maximum speed when the car is lifted by applying a load corresponding to the rated load on the car. When the weight difference between the car and the counterweight is small, for example, when the occupancy rate is about 40% to 60%, the output of the hoisting machine required to raise and lower the car at the rated speed is It may be smaller than when the weight difference is large. That is, there is a margin in the output of the hoisting machine (motor) even when the car is run at the rated speed. Therefore, it is possible to increase the traveling speed beyond the rated speed. For example, if the rated speed is 45 m / min, the traveling speed can be increased to 60 m / min. The elevator control device 30 of the elevator 40 is faster than the rated speed by controlling the rotational speed of the hoisting machine and the like based on the control signal from the group management control device 10 when the speed-up traveling condition is established. The car (elevator 40) is caused to travel at the traveling speed. Hereinafter, appropriately traveling each elevator 40 at a traveling speed faster than the rated speed is referred to as “speed-up traveling”.

The signal is output to the group management control device 10.

2. Operation of group management system 2-1. Operation of Destination Floor Registration Device First, the operation of the destination floor registration device will be described. The destination floor registration device 20 receives a destination floor registration operation by a user in the operation unit 25. The registration control unit 21 of the destination floor registration apparatus 20 includes destination floor information indicating the destination floor registered by the user and a departure floor indicating the installation floor of the destination floor registration apparatus 20 on which the operation for registering the destination floor has been performed. An allocation request signal including the information and identification information for identifying the destination floor registration device 20 is generated. The control unit of the destination floor registration device 20 outputs the generated assignment request signal to the group management control device 10.

  In addition, the registration control unit 21 of the destination floor registration device 20 receives the assigned number machine information indicating the assigned number machine from the group management control device 10 as a response to the above-described assignment request signal. The registration control unit 21 of the destination floor registration device 20 causes the display unit 24 to display the destination floor registered by the user and the information indicating the assigned number indicated by the assigned number information. As a result, the destination floor registration device 20 notifies the user that the registered destination floor is assigned to the displayed assigned number.

2-2. Operation of Group Management Control Device The group management control unit 11 of the group management control device 10 shown in FIG. 1 reads a program from the storage unit 12 and uses various data stored in the storage unit 12 based on the program. By performing various arithmetic processes, the functions of the unit allocation unit 10A, the predicted waiting time table creation unit 10B, the travel time table creation unit 10C, and the speed switching command unit 10D shown in FIG. 3 are realized. The various data stored in the storage unit 12 include a normal travel time table Tro, a first speed-up travel time table Tra, a second speed-up travel time table Trb, and a pre-provisional prediction waiting time table Tw1 shown in FIG. And a provisional post-allocation estimated waiting time table Tw2. In the following description, the first speed-up travel time table Tra and the second speed-up travel time table Trb may be collectively referred to as “speed-up travel time table Tr”.

2-2-1. Operation of unit allocation unit 2-2-1-1. Speed Up Travel Judgment Operation The car assignment unit 10A judges whether or not there is a travel section that satisfies the speed up travel condition for each elevator 40 (unit). The speed-up travel condition is that (1) the travel distance of the travel section is equal to or greater than the target travel distance, and (2) the boarding rate of the travel section is within the target boarding rate range. The boarding rate is, for example, the ratio of the number of passengers to the number of passengers in the car, and the number of passengers can be obtained from the registered number of destination floor calls. The range of the target boarding rate is a range of boarding rates in which traveling at a higher speed is possible. The range of the target boarding rate is set based on a range in which the weight difference between the car (including the user) and the counterweight is equal to or less than a predetermined amount that allows traveling at a higher speed. The travel distance is the distance in the vertical direction when the elevator 40 is traveling up or down. Since the elevator 40 travels between floors, the travel distance can be obtained as the inter-floor distance between the departure floor and the destination floor. The target travel distance is a preset travel distance that provides a desired travel time shortening effect when speed-up travel is performed. The target travel distance may be set to an arbitrary value according to the target travel time reduction amount.

2-2-1-2. Group management control operation The unit assignment unit 10A performs a process of assigning the destination floor registered by the destination floor registration device 20 to any one of the elevators 40A to 40F. Specifically, when the allocation request signal is received from the destination floor registration device 20 via the input / output interface 13, the car allocation unit 10 </ b> A starts the allocation process for the elevator 40. This assignment request signal is a signal that requests the destination floor registered by the destination floor registration device 20 to be assigned to one of the elevators 40A to 40F. The allocation request signal includes destination floor information indicating the destination floor registered by the user, departure floor information indicating the floor (departure floor) where the destination floor is registered, and the destination floor where the destination floor is registered. And identification information for identifying the registration device 20. The unit allocation unit 10A allocates the destination floor indicated by the received allocation request signal to one of the elevators 40A to 40F.

  Specifically, when the elevator assignment unit 10A receives an elevator assignment request signal for a destination floor call from the destination floor registration device 20 via the input / output interface 13, the elevator assignment unit 10A includes an elevator ( Judge whether there is an elevator capable of traveling at a higher speed. When there is an elevator capable of traveling at a higher speed, the number assignment unit 10A determines an assigned number from the elevators capable of traveling at a higher speed. On the other hand, when there is no elevator capable of traveling at a higher speed, the number assignment unit 10A determines an assigned number among all elevators.

  Specifically, the number assignment unit 10A determines the elevator 40 (assignment number) to which the destination floor is to be assigned based on the operation information of each elevator 40. More specifically, the number assignment unit 10A calculates, for each elevator 40, an evaluation value for selecting the elevator 40 (assignment number) to which the destination floor is assigned based on the operation information of each elevator 40. Here, the operation information of each elevator 40 includes, for example, a car state (including a car position, a traveling direction, a door open / close state, a load, etc.), a predicted waiting time (predicted waiting time), and a prediction. Information indicating the service completion time (time until the assigned car arrives at the destination floor), the scheduled number of stops of the car (number of elevators 40 scheduled to be completed before service completion), and the like. After the evaluation value is calculated, the unit allocation unit 10A selects the elevator 40 having the highest evaluation value from the elevators 40A to 40F, and allocates the destination floor to the selected elevator 40.

  In the present embodiment, the predicted waiting time is recorded in a pre-temporary prediction waiting time table Tw1 and a post-temporary prediction waiting time table Tw2, which will be described later. The unit allocation unit 10A performs, for example, the following processing based on both the pre-temporary prediction waiting time table Tw1 and the post-temporary prediction waiting time table Tw2. That is, the unit allocation unit 10A temporarily allocates a new destination floor call to unit i, uses the post-provisional estimated waiting time table Tw2 for the temporarily allocated unit i, and temporarily allocates the remaining units not allocated. The waiting time for all passengers is obtained using the current prediction waiting time table Tw1. And 10A of unit allocation part calculates | requires the total value or average value of the waiting time for all the passengers about all the units. Furthermore, the number assigning unit 10A changes the number i of the number assigned temporarily and similarly obtains the total value or average value of waiting times for all passengers for all the numbers. Then, the unit allocation unit 10A sets the evaluation value related to the predicted waiting time at a unit having the smallest total value or average value of the waiting times of all units after provisional allocation to a higher value than other units. As a result, the unit i having the smallest total value or average value of the waiting times of all the units after provisional allocation is easily allocated to the new destination floor call.

  Based on the result of the above allocation process, the number assignment unit 10A outputs a control signal instructing traveling from the departure floor to the destination floor to the elevator control device 30 of the assignment number. In addition, when the speed can be increased, the number-assignment unit 10A outputs a speed-up instruction signal for causing the speed switching command unit 10D to cause the elevator control device 30 of the assigned number to perform a speed-up running.

  In addition, the number assignment unit 10A transmits, as a response to the assignment request signal, assigned number information indicating the number assigned to the destination floor registration device 20 in which the destination floor is registered via the input / output interface 13.

2-2-2. Operation of Speed Switching Command Unit When the speed switching command unit 10D receives the speed up instruction signal from the number assignment unit 10A, the speed switching command unit 10D transmits a speed switching signal to the elevator control device 30 of the number assignment unit via the input / output I / F 13. Thereby, in the assigned number machine, the rotational speed of the hoisting machine (motor) is increased, and the traveling speed of the car is increased.

2-2-3. Operation of Travel Time Table Creation Unit The travel time table creation unit 10C is normally used at a predetermined time (for example, during a travel test) before the start of actual operation of the elevator 40 (before the start of service to a user), for example. The travel time table Tro, the first speed up travel time table Tra, and the second speed up travel time table Trb are created, and the created normal travel time table Tro, the first speed up travel time table Tra, and the second speed up travel A time table Trb is stored. The normal travel time table Tro is a travel time table that records the travel time between floors when normal travel that is not speed-up travel is performed. The first speed-up travel time table Tra and the second speed-up travel time table Trb are tables that record the travel time between floors when speed-up travel is performed. The first speed up travel time table Tra records the travel time between floors when the departure floor or the destination floor is the lobby floor (first floor), and the second speed up travel time table Trb is the departure floor and the destination floor. In either case, the travel time between floors when the lobby floor (the first floor) is not recorded. Here, the traveling time is the time from when the elevator 40 starts accelerating on the departure floor until the elevator 40 decelerates on the destination floor and stops completely. In the following description, the first speed up travel time table Tra and the second speed up travel time table Trb may be collectively referred to as “speed up travel time table Tr”.

  The travel time table creation unit 10C updates the normal travel time table Tro, the first speed-up travel time table Tra, and the second speed-up travel time table Trb after the actual operation of the elevator 40 on site is started. For example, when the elevator 40 is normally traveled, the normal travel time table Tro is updated. When the elevator 40 is caused to travel at a higher speed, the first speed up traveling time table Tra or the second speed up traveling time table Trb is updated. The update is performed, for example, when a response is made to one destination floor call. The update may be performed when a response is made to a predetermined number of destination floor calls.

  Here, the traveling time of each elevator 40 may differ due to individual differences of the elevator 40, aging deterioration, etc., but even in such a case by updating each traveling time table as in this configuration. Accurate prediction waiting time can be obtained.

  FIG. 4 is a diagram illustrating an example of a travel time table in the elevator group management system according to the first embodiment. Specifically, FIG. 4A is a diagram illustrating an example of the normal travel time table Tro. FIG. 4B is a diagram showing the first speed-up travel time table Tra. FIG. 4C shows the second speed-up travel time table Trb. In addition, each travel time table of FIG.4 (a), FIG.4 (b), and FIG.4 (c) has shown the case where the building where the elevator 40 is installed is a building of the aspect shown in FIG. FIG. 5 is a diagram illustrating a floor configuration of a building to which the elevator group management system according to the first embodiment is applied. As shown in FIG. 5, the building is a six-story building, and the first floor (lobby floor) has a height of h0, the second floor, the third floor, the fourth floor, and the fifth floor, respectively. . Therefore, the travel time required for the elevator 40 to travel on the first floor (lobby floor) portion and the travel time required to travel on the other floor portions are different. Therefore, the group management system according to the present embodiment includes a first speed-up travel time table Tra that records travel time between floors when the departure floor or the destination floor is a lobby floor, as shown in FIG. As shown in FIG. 4C, there is a second speed-up travel time table Trb that records the travel time between floors when the departure floor and the destination floor are not lobby floors.

  The normal travel time table Tro shown in FIG. 4A records the travel time based on the actual travel time between floors during normal travel. In the normal travel time table Tro, the travel time between floors is recorded in a matrix form as a combination of the departure floor and the destination floor. For example, if the departure floor is the first floor and the destination floor is the second floor, the third floor, the fourth floor, the fifth floor, and the sixth floor, the travel times between the floors are 3 seconds, 5 seconds, 7 seconds, and 8 seconds, respectively. 9 seconds. If the departure floor is the second floor and the destination floor is the first floor, the third floor, the fourth floor, the fifth floor, and the sixth floor, the travel time between the floors is 3 seconds, 2 seconds, 4 seconds, and 6 seconds, respectively. 7 seconds. Similarly, when the departure floor is the third floor to the sixth floor, the traveling time between the floors is recorded corresponding to each destination floor.

  The first speed-up travel time table Tra shown in FIG. 4B records the travel time based on the actual travel time between floors when the departure floor or the destination floor is the lobby floor during speed-up travel. Yes. In the first speed-up traveling time table Tra, the traveling time between floors is recorded in correspondence with the number of moving floors. For example, when the number of moving floors is the third floor, the fourth floor, and the fifth floor, the travel times between the floors are 6 seconds, 7 seconds, and 8 seconds, respectively. Note that when the number of moving floors is the first floor and the second floor, the travel time between the floors is not recorded because the travel distance does not satisfy the speed-up travel condition.

  Here, after the actual operation is started at the site where the elevator 40 is installed, generally, the opportunity for speeding-up traveling is less than the chance for normal traveling or biased. For this reason, the update frequency of the travel time during speed-up travel is reduced. However, the number of patterns of the moving floor number is smaller than the number of combination patterns of the departure floor and the destination floor. Therefore, by recording and updating the travel time between floors corresponding to the number of moving floors as in this embodiment, the travel time table is updated even when there are few opportunities for speed-up travel as described above. Can be done with high frequency. Therefore, the accuracy of the calculated waiting time can be improved.

  The second speed-up travel time table Trb shown in FIG. 4C records the travel time based on the actual travel time between floors when the departure floor and the destination floor are not lobby floors during speed-up travel. ing. In the second speed-up travel time table Trb, the travel time between floors is recorded in correspondence with the number of moving floors. For example, when the number of moving floors is the third floor and the fourth floor, the traveling time between the floors is 5 seconds and 6 seconds, respectively. Note that when the number of moving floors is the first floor and the second floor, the travel time between the floors is not recorded because the travel distance does not satisfy the speed-up travel condition. Also, in the building, if neither the departure floor nor the destination floor is a lobby floor, there is no case where the number of moving floors is 5 floors, so there is no space between floors when the moving floor number is 5 floors. Travel time is not recorded.

2-2-4. Operation of Predictive Wait Time Table Creation Unit As shown in FIG. 3, the predictive wait time table creation unit 10B includes the normal travel time table Tro, the first speed up travel time table Tra, and the second speed up travel time table Trb. Based on this, a pre-temporary prediction waiting time table Tw1 and a post-temporary prediction waiting time table Tw2 are created, and the created pre-temporary prediction waiting time table Tw1 and post-temporary prediction waiting time table Tw2 are stored.

  In the present embodiment, the predicted waiting time table creation unit 10B generates a new destination floor call when a user registers a destination floor by operating the destination floor registration device 20 on a certain landing floor, and the unit allocation unit 10A When the signal indicating the destination floor call is received from the destination floor registration device 20, the temporary waiting time prediction waiting time table Tw1 and the temporary waiting time waiting time table Tw2 after temporary assignment are generated. The predicted waiting times indicated in the columns of the respective floors of the pre-provisional prediction waiting time table Tw1 and the post-temporary prediction waiting time table Tw2 are received by the unit assignment unit 10A from the destination floor registration device 20 as a signal indicating a destination floor call. This is a predicted value of the time from when the elevator 40 arrives at each floor.

  FIG. 6 is a diagram illustrating an example of the predicted waiting time table. Specifically, FIG. 6A is a diagram illustrating an example of the pre-provisional prediction waiting time table Tw1. FIG. 6B is a diagram illustrating an example of the temporary allocation predicted waiting time table Tw2. The predicted waiting time table creation unit 10B has a predicted waiting time table Tw1 before temporary allocation and a predicted waiting time table Tw2 after temporary allocation for each elevator (each car). FIGS. 6A and 6B show an example of a predicted waiting time table in a certain elevator.

  In the present embodiment, the predicted waiting time table creation unit 10B generates a new destination floor call when a user registers a destination floor by operating the destination floor registration device 20 on a certain landing floor, and the unit allocation unit 10A When the signal indicating the destination floor call is received from the destination floor registration device 20, the temporary waiting time prediction waiting time table Tw1 and the temporary waiting time waiting time table Tw2 after temporary assignment are generated. The prediction allocation waiting time shown in the upper (upward) and downward (downward) columns of each floor of the temporary allocation predicted waiting time table Tw1 and the temporary allocation predicted waiting time table Tw2 This is a predicted value of the time from when the signal indicating the destination floor call is received from the floor registration device 20 until the elevator 40 arrives at each floor in the upward or downward direction. Here, arrival at each floor means that the elevator 40 has stopped at each floor. The predicted waiting time may be a predicted value of the time until the door is completely opened after stopping on each floor.

  The predicted waiting time of each floor is obtained based on, for example, the travel time between floors and a predetermined stop time per stop ("stop_t" described later). The predetermined stoppage time per stop is the closing time of the door when leaving the departure floor, the time from the arrival of the destination floor to the opening of the door until the start of closing the door to leave the destination floor Etc. In the present embodiment, the predetermined stop time is set to 1.5 seconds as an initial value, for example. In addition, you may change predetermined stop time based on the measured value in the field. In this case, the predetermined stop time may be an average value of stop times acquired when traveling a plurality of times.

  In each prediction waiting time table of FIG. 6A and FIG. 6B, the building where the elevator 40 is installed is a building of the form shown in FIG. 5 and the destination floor call is assigned as shown in FIG. Indicates the case. FIG. 7 is a diagram illustrating an example of a traveling pattern in the elevator group management system according to the first embodiment. Specifically, FIG. 7A is a diagram illustrating an example of a running pattern when a new destination floor call is not assigned (before provisional assignment). FIG.7 (b) is a figure which shows an example of the driving | running pattern at the time of assigning a new destination floor call temporarily (after temporary allocation).

  In the travel pattern before temporary allocation shown in FIG. 7A, it is assumed that the elevator is currently stopped on the first floor and is in a state immediately before departure, and scheduled to stop on the fourth, fifth and sixth floors. In this example, the target travel distance is the distance between the floors where the number of moving floors corresponds to the third floor, and the range of the target boarding rate is 40% to 60%. In the rising travel section SA from the first floor (lobby floor) to the fourth floor, the boarding rate is 50% and within the target boarding rate range, the number of moving floors is the third floor, and the travel distance is longer than the target travel distance . Therefore, it is possible to travel at a higher speed in the ascending travel section SA. In the ascending travel section SB from the 4th floor to the 5th floor, the boarding rate W is 30%, which is not within the target boarding rate range, the number of moving floors is 1st floor, and the travel distance is shorter than the target travel distance. . Therefore, it is not possible to perform speed-up travel in the ascending travel section SB. In the ascending travel section SC from the 5th floor to the 6th floor, the boarding rate W is 10%, which is not within the target boarding rate range, the number of moving floors is 1st floor, and the travel distance is shorter than the target travel distance. . Therefore, it is not possible to perform speed-up travel in the ascending travel section SC. In the descending travel section SD from the sixth floor to the first floor, the boarding rate W is 40%, which is within the target boarding rate range, the number of moving floors is the fifth floor, and the travel distance is longer than the target travel distance. . Therefore, it is possible to travel at a higher speed in the descending travel section SD.

  FIG. 7B shows a driving pattern when a new destination floor call from the third floor to the fifth floor is temporarily assigned to the elevator 40 in the state shown in FIG. In this example, by temporarily assigning a new destination floor call from the 3rd floor to the 5th floor, the ascending travel section SA from the 1st floor to the 4th floor becomes the ascending travel section SA1 from the 1st floor to the 3rd floor and the 3rd floor To the 4th floor ascending travel section SA2. In this case, in the ascending travel section SA1 from the first floor (lobby floor) to the third floor, the boarding rate W is 50% and within the target boarding rate range, but the number of moving floors is the second floor and the travel distance is It is shorter than the target mileage. For this reason, in the ascending travel section SA1, it is not possible to perform speed-up travel. In the ascending travel section SA2 from the third floor to the fourth floor, the boarding rate W is 55%, which is within the target boarding rate range, but the number of moving floors is the first floor and the travel distance is shorter than the target travel distance. . Therefore, it is not possible to perform speed-up travel in the ascending travel section SA2. In the ascending travel section SB from the 4th floor to the 5th floor, the boarding rate W is 35% and is not within the target boarding rate range, the number of moving floors is 1st floor, and the travel distance is shorter than the target travel distance. . Therefore, it is not possible to perform speed-up travel in the ascending travel section SB. In addition, in the ascending travel section SC from the 5th floor to the 6th floor and the descending travel section SD from the 6th floor to the 1st floor, even when a new destination floor call from the 3rd floor to the 5th floor is assigned to the elevator 40, There is no change in the occupancy rate W and the travel distance, and in the ascending travel section SC, it is maintained in a state where it cannot perform speed-up travel, and in the descending travel section SD, it is maintained in a state where speed-up travel can be performed. Is done.

  The group management control device 10 sets 1 as the machine number i (S11). In the present embodiment, six elevators 40A to 40F are referred to as No. A to No. F, but No. A to No. F correspond to Nos.

  The group management control device 10 sets 1 as the departure floor SF (S12).

  The group management control device 10 sets 1 as the destination floor DF (S13).

  The group management control device 10 determines whether or not the departure floor SF and the destination floor DF are equal (S14).

  When the departure floor SF and the destination floor DF are equal (YES in S14), the group management control device 10 adds 1 to the destination floor DF (S15), and performs the determination in step S14 again. That is, the group management control device 10 sets the destination floor DF as the destination floor on the first floor while leaving the departure floor SF as the current floor, and performs the determination in step S14 again.

  When the departure floor SF and the destination floor DF are not equal (NO in S14), the group management control device 10 causes the i-th unit to travel from the departure floor SF to the destination floor DF, and after leaving the departure floor SF, the destination floor The travel time until arrival at the DF is measured (S16).

  The group management control device 10 records the measured travel time in the columns of the departure floor SF and the destination floor DF of the normal travel time table Tro of the i-th car (S17).

  The group management control device 10 determines whether or not the measurement of the travel time for all destination floors has been completed for the current departure floor SF (S18).

  When the measurement of the travel time for all the destination floors has not been completed (NO in S18), the group management control device 10 adds 1 to the destination floor DF (S15), and performs the determination in step S14 again.

  When the measurement of travel time is completed for all destination floors (YES in S18), the group management control device 10 determines whether the measurement of travel time is completed for all departure floors (S19).

  If the measurement of the travel time for all departure floors has not been completed (NO in S19), the group management control device 10 adds 1 to the departure floor SF (S20), and performs the processing after step S13. That is, the group management control device 10 sets the departure floor SF to the departure floor on the first floor, and performs the processing after step S13.

  When measurement of travel time is completed for all departure floors (YES in S19), the group management control device 10 determines whether measurement of travel time is completed for all elevators (all units) (S21). .

  If the measurement of the travel time for all elevators has not been completed (NO in S21), the group management control device 10 adds 1 to the car number i (S22), and performs the processing after step S12. That is, the group management control device 10 sets the next elevator (unit) and performs the processes after step S12.

  When the measurement of the travel time is completed for all the elevators (YES in S21), the group management control device 10 completes the process of creating the normal travel time table Tro.

  Note that the travel time may be measured a plurality of times in each direction on each floor, and the average value may be recorded in the column for each direction on each floor of the normal travel time table Tro. Thereby, the precision of the travel time recorded in the normal travel time table Tro can be improved.

2-3-3. Creation Operation of Speed Up Travel Time Table The creation operation of the first speed up travel time table Tra and the second speed up travel time table Trb in the elevator group management system of the present embodiment will be described. FIG. 10 is a flowchart showing a creation operation of the first speed-up travel time table Tra and the second speed-up travel time table Trb in the elevator group management system according to the first embodiment. In steps S31 to S35 and S41 to 45, processing similar to steps S11 to S15 and S18 to 22 in FIG. 9 is performed.

  The group management control device 10 sets 1 as the machine number i (S31).

  The group management control device 10 sets 1 as the departure floor SF (S32).

  The group management control device 10 sets 1 as the destination floor DF (S33).

  The group management control device 10 determines whether or not the departure floor SF and the destination floor DF are equal (S34).

  If the departure floor SF and the destination floor DF are equal (YES in S34), the group management control device 10 adds 1 to the destination floor DF (S35), and performs the determination in step S34 again. That is, the group management control device 10 sets the destination floor DF as the destination floor on the first floor while leaving the departure floor SF as the current floor, and performs the determination in step S14 again.

  When the departure floor SF and the destination floor DF are not equal (NO in S34), the group management control device 10 determines whether or not the distance from the departure floor SF to the destination floor DF is equal to or greater than the predetermined distance C (S36). The predetermined distance C is a minimum distance that allows traveling at a higher speed.

  If the distance from the departure floor SF to the destination floor DF is not equal to or greater than the predetermined distance C (NO in S36), the group management control device 10 adds 1 to the destination floor DF (S35) and performs the determination in step S34 again. Note that if the distance from the departure floor SF to the destination floor DF is not equal to or greater than the predetermined distance C, the traveling time is not acquired for the section because the speed-up traveling is impossible.

  When the distance from the departure floor SF to the destination floor DF is equal to or greater than the predetermined distance C (YES in S36), the group management control device 10 speeds up the No. i machine from the departure floor SF to the destination floor DF, and The travel time from departure from SF to arrival at destination floor DF is measured (S37).

  The group management control device 10 determines whether the departure floor SF or the destination floor DF is a lobby floor (S38).

  When the departure floor SF or the destination floor DF is the lobby floor (YES in S38), the group management control device 10 uses the measured traveling time to correspond to the number of moving floors in the first speed-up traveling time table Tra of No. i machine. (S39). The corresponding moving floor number is | SF−DF |, that is, the absolute value of the value obtained by subtracting the value of the destination floor DF from the value of the departure floor SF.

  Here, in the process of sequentially executing the processing according to this flowchart for all departure floors and all destination floors, the number of movement floors | SF-DF | obtained in this step S39 is the movement floor obtained so far. It may be the same as the number of floors. For example, when the departure floor SF is the second floor and the destination floor DF is the fifth floor, when the departure floor SF is the third floor and the destination floor DF is the sixth floor, when the departure floor SF is the sixth floor and the destination floor DF is the third floor, When the departure floor SF is the fifth floor and the destination floor DF is the second floor, the moving floor number | SF-DF | becomes the third floor in both cases. When the departure floor SF is the second floor and the destination floor DF is the sixth floor, and when the departure floor SF is the sixth floor and the destination floor DF is the second floor, the moving floor number | SF-DF | Become the floor. In these cases, the group management control device 10 performs the following processing.

  That is, the group management control device 10 determines whether or not the traveling time is recorded in the column corresponding to the determined moving floor number | SF-DF | in the first speed-up traveling time table Tra of the i-th car. . When the travel time is not recorded in the column corresponding to the obtained moving floor number, the group management control device 10 determines the traveling time measured this time for the traveling section measured this time. Record in the column corresponding to. On the other hand, when the travel time is recorded in the column corresponding to the obtained number of moving floors | SF-DF |, the group management control device 10 newly measures the travel time already recorded. An average value of the travel time is obtained by weighted averaging the travel time based on the number of updates so far, and the obtained travel time is recorded in a column corresponding to the number of moving floors in the current travel section. That is, the group management control device 10 updates the travel time in the column corresponding to the number of moving floors in the current travel section. Thereby, the precision of the traveling time recorded in the first speed-up traveling time table Tra can be improved. In this step 39, the number of updates may be stored in association with the number of moving floors (column corresponding to the number of moving floors). Instead of determining whether or not the travel time is recorded in the column corresponding to the obtained moving floor number | SF-DF |, the group management control device 10 determines the obtained moving floor number | SF-DF. It may be determined whether or not a default value (for example, “0”) is recorded in the column corresponding to |.

  On the other hand, when the departure floor SF or the destination floor DF is not the lobby floor (NO in S38), the group management control device 10 moves the measured travel time to the corresponding travel floor in the second speed-up travel time table Trb of No. i machine. Recorded in the floor number column (S40). As described above, the corresponding moving floor number is | SF−DF |, that is, the absolute value of the value obtained by subtracting the value of the destination floor DF from the value of the departure floor SF. In this step S40, the group management control device 10 in the same manner as in step S39, the traveling time is entered in the column corresponding to the obtained moving floor number | SF-DF | in the second speed-up traveling time table Trb of No. i machine. Is recorded, or whether a default value (for example, “0”) is recorded in the column corresponding to the obtained moving floor number | SF-DF | An averaging process is performed on the travel time measured in the above, and the travel time is recorded in the second speed-up travel time table Trb.

  The group management control device 10 determines whether or not the measurement of the travel time of all the destination floors DF has been completed for the current departure floor SF (S41).

  If the measurement of the travel time for all the destination floors has not been completed (NO in S41), the group management control device 10 adds 1 to the destination floor DF (S35), and performs the determination in step S34 again.

  When measurement of travel time is completed for all destination floors (YES in S41), the group management control device 10 determines whether measurement of travel time is completed for all departure floors (S42).

  If the measurement of the travel time for all departure floors has not been completed (NO in S42), the group management control device 10 adds 1 to the departure floor SF (S43), and performs the processing after step S33. That is, the group management control device 10 sets the departure floor SF to the departure floor on the first floor, and performs the processing after step S33.

  When measurement of travel time is completed for all departure floors (YES in S42), the group management control device 10 determines whether measurement of travel time is completed for all elevators (units) (S44).

  If the measurement of the travel time for all elevators has not been completed (NO in S44), the group management control device 10 adds 1 to the car number i (S45), and performs the processing after step S32. That is, the group management control device 10 sets the next elevator and performs the processes after step S32.

  When the travel time measurement is completed for all the elevators (YES in S44), the group management control device 10 completes the process of creating the first speed-up travel time table Tra and the second speed-up travel time table Trb.

  Note that the travel time is measured multiple times in each direction on each floor, and the average value is recorded in the corresponding number of moving floors column in the first speed up travel time table Tra and the second speed up travel time table Trb. May be. Thereby, the precision of the travel time recorded on the 1st speed up travel time table Tra and the 2nd speed up travel time table Trb can be improved.

2-3-4. Various Travel Time Table Update Operations Next, various travel time table update operations in the elevator group management system of the present embodiment will be described. FIG. 11 is a flowchart illustrating an operation of updating the travel time table in the elevator group management system according to the first embodiment. In the present embodiment, the group management control device 10 causes the No. i machine to travel from the departure floor (f floor) to the destination floor (d floor) based on the destination floor call, and when the completion of traveling is detected, the departure floor (f Floor) to the destination floor (d floor), whether it is a speed up travel section, a normal travel section, whether the departure floor or the destination floor is a lobby floor, etc., and the first speed up travel time table Tra The travel time table of either the normal travel time table Tro or the second speed-up travel time table Trb is updated.

  Specifically, when the group management control device 10 detects the completion of traveling from the departure floor (floor f) to the destination floor (floor d) based on the destination floor call (S51), the traveling is increased in speed. It is determined whether or not (travel) (S52).

  If the travel is speed-up travel (YES in S52), the group management control device 10 determines whether the departure floor (f floor) or the destination floor (d floor) is the lobby floor (S53).

  When the departure floor (f floor) or the destination floor (d floor) is the lobby floor (YES in S53), the group management control device 10 corresponds to the number of moving floors corresponding to the first speed-up travel time table Tra of the No. i machine. Update the travel time value in the column of (| f−d |, that is, the absolute value of the value obtained by subtracting the value of the destination floor d from the value of the departure floor f) based on the travel time measured this time (S54), The update process ends. Note that the value to be updated is obtained, for example, by performing a weighted average of the average travel time acquired so far and the travel time measured this time based on the number of updates so far.

  On the other hand, when the departure floor (floor f) or the destination floor (floor d) is not the lobby floor (NO in S53), the group management control device 10 moves correspondingly in the second speed-up travel time table Trb of No. i machine. Update the travel time value in the column of the number of floors (| f−d |, ie, the absolute value of the value obtained by subtracting the value of the destination floor d from the value of the departure floor f) based on the travel time measured this time ( S55), the update process is terminated.

  On the other hand, when the travel is not speed-up travel in step S52 (NO in S52), the group management control device 10 determines the travel time in the columns of the departure floor f and the destination floor d of the normal travel time table Tro of the i-th car. The value is updated based on the travel time measured this time (S56), and the update process is terminated.

2-3-5. Prediction Waiting Time Table Creation Operation The prediction waiting time table creation operation in the elevator group management system of the present embodiment will be described. FIG. 12 is a flowchart illustrating an operation of creating a predicted waiting time table in the elevator group management system according to the first embodiment. The waiting time table is created before the actual operation of the elevator 40 is started (before the building is opened to general users) with a weight corresponding to the weight when the boarding rate is about 50%. This is done by running the elevator 40 in the mounted state.

  The group management control device 10 sets 1 as the machine number i (S61).

  The group management control device 10 sets 0 (zero) as the predicted waiting time initial value sumt (S62).

  The group management control device 10 sets the current floor of the car as the calculation target floor fc, the prediction waiting time calculation start floor f0, and the previous stop floor fp of the prediction waiting time WT (i, fc, vc), and the prediction waiting time. Traveling direction vc (hereinafter referred to as “calculation traveling direction vc”) used for calculation of WT (i, fc, vc), traveling direction v0 of the car at the start of calculation of predicted waiting time WT (i, fc, vc) (Hereinafter referred to as “calculation start direction v0”), the current traveling direction of the car is set as the traveling direction vp of the car at the previous stop (hereinafter referred to as “previous traveling direction vp”) (S63). The current floor of the car and the current traveling direction may be detected by a known method.

  The group management control device 10 sets 0 (zero) as the predicted waiting time WT (i, fc, vc) in the column of the v direction on the f-th floor of the predicted waiting time table of the i-th unit (S64).

  The group management control device 10 determines whether or not the traveling direction vc for calculation of the predicted waiting time WT (i, fc, vc) is upward (UP) (S65).

  When the traveling direction vc for calculation of the predicted waiting time WT (i, fc, vc) is upward (UP) (YES in S65), the group management control device 10 adds 1 to the calculation target floor fc (S66). ).

  When the traveling direction vc for calculation of the predicted waiting time WT (i, fc, vc) is not upward (UP) (NO in S65), that is, when it is downward (DOWN), the group management control device 10 calculates 1 is subtracted from the floor fc (S67).

  The group management control device 10 determines whether or not the calculation traveling direction vc of the predicted waiting time WT (i, fc, vc) is the upward direction (UP) and the calculation target floor fc is the top floor (S68).

  When the calculation traveling direction vc of the prediction waiting time WT (i, fc, vc) is the upward direction (UP) and the calculation target floor fc is the top floor (YES in S68), the group management control device 10 waits for the prediction. The downward direction (DOWN) is set as the traveling direction vc for calculating the time WT (i, fc, vc) (S69).

  On the other hand, when the traveling direction vc for calculation of the predicted waiting time WT (i, fc, vc) is the upward direction (UP) and the calculation target floor fc is not the top floor (NO in S68), the group management control device 10 Then, it is determined whether or not the traveling direction vc for calculation of the predicted waiting time WT (i, fc, vc) is the downward direction (DOWN) and the calculation target floor fc is the lowest floor (S70).

  When the traveling direction vc for calculation of the predicted waiting time WT (i, fc, vc) is the downward direction (DOWN) and the calculation target floor fc is the lowest floor (YES in S70), the group management control device 10 predicts The upward direction (UP) is set as the travel direction vc for calculating the waiting time WT (i, fc, vc) (S71).

  When the traveling direction vc for calculation of the predicted waiting time WT (i, fc, vc) is the downward direction (DOWN) and the calculation target floor fc is not the lowest floor (NO in S70), or when step S69 or S71 is executed The group management control device 10 travels the car when the calculation target floor fc is the predicted waiting time calculation start floor f0 and the calculation travel direction vc starts the calculation of the predicted waiting time WT (i, fc, vc). It is determined whether or not the direction is v0 (calculation start direction v0) (S72).

  When the condition that the calculation target floor fc is the predicted waiting time calculation start floor f0 and the calculation travel direction vc is the calculation start direction v0 is satisfied (YES in S72), the group management control device 10 It is determined whether or not the process for creating the predicted waiting time table for (unit) has been completed (S73).

  When the process for creating the predicted waiting time table is completed for all the elevators (YES in S73), the group management control device 10 completes the process for creating the predicted waiting time table.

  When the process of creating the predicted waiting time table for all elevators has not been completed (NO in S73), the group management control device 10 adds 1 to the car number i (S74), and the processes after step S62 described above. Execute.

  When the condition that the calculation target floor fc is the predicted waiting time calculation start floor f0 and the calculation traveling direction vc is the calculation start direction v0 is not satisfied (NO in S72), the group management control device 10 determines that the elevator is When starting (departing) the previous stop floor fp in the previous travel direction vp and stopping in the calculation travel direction vc on the calculation target floor fc, it is determined whether or not the speed-up travel condition is satisfied. (S75).

  When the speed-up traveling condition is satisfied (YES in S75), the group management control device 10 corresponds to the previous stop floor fp (corresponding to the departure floor in this step) or the calculation target floor fc (corresponding to the destination floor in this step). ) Is a lobby floor (S76).

  When the previous stop floor fp or the calculation target floor fc is the lobby floor (YES in S76), the group management control device 10 uses the estimated speed waiting time WT (i, fc, vc) as the first speed-up traveling time of the No. i machine. A value obtained by adding the x floor travel time RUN2A (i, | fp−fc |) of the table Tra and the predicted waiting time initial value sumt is set (S77). Here, the x floor travel time RUN2A (i, | fp-fc |) is the travel time when the departure floor or the destination floor is the lobby floor.

  On the other hand, when the previous stop floor fp or the calculation target floor fc is not the lobby floor (NO in S76), the group management control device 10 uses the second speed of the i-th unit as the predicted waiting time WT (i, fc, vc). A value obtained by adding the x floor travel time RUN2B (i, | fp-fc |) of the up travel time table Trb and the predicted waiting time initial value sumt is set (S78). Here, the x floor travel time RUN2B (i, | fp-fc |) is the travel time when neither the departure floor nor the destination floor is a lobby floor.

  On the other hand, when the speed-up travel condition is not satisfied in step S75 (NO in S75), the group management control device 10 travels in the normal travel time table Tro of No. i as the predicted waiting time WT (i, fc, vc). A value obtained by adding the time RUN1 (i, fp, fc |) and the predicted waiting time initial value sumt is set (S79).

  When any one of steps S77, S78, and S79 is performed, the group management control device 10 determines whether or not the calculation target floor fc is scheduled to stop in the calculation travel direction vc (S80).

  When the calculation target floor fc is scheduled to stop in the calculation travel direction vc (YES in S80), the group management control device 10 sets the predicted waiting time WT (i, fc, vc) and a predetermined value as the predicted waiting time initial value sumt. A value obtained by adding the stop time stop_t is set (S81).

  The group management control device 10 sets the calculation target floor fc as the previous stop floor fp and sets the calculation travel direction vc as the previous travel direction vp (S82).

2-4. Specific example of creation of predicted waiting time table 2-4-1. Specific Example of Creating Pre-Temporary Prediction Prediction Waiting Time Table A specific example of creating the pre-temporary prediction waiting time table Tw1 of FIG. 6A will be described. In addition, although this example demonstrates the case where the prediction waiting time table of one elevator (unit) is created, the creation process is performed for each unit of the plurality of elevators 60.

-Upstairs-
Since the relevant machine is stopped on the first floor, the predicted waiting time WT (1, 1, up) is 0 seconds. The predicted waiting time WT (1, 1, up) is recorded in the first floor column in the upward direction (UP).

-Upstairs 2nd-
This unit will run up from the first floor (lobby floor) to the second floor. In this case, since the number of moving floors is 1st floor and the travel distance is shorter than the target travel distance, it is not possible to perform speedup travel. Therefore, the column of the first floor and the second floor of the destination floor in the normal travel time table Tro is referred to obtain 3 seconds of the travel time RUN1 (1, 1, 2), and the predicted waiting time WT (1, 2) , Up) is 3 seconds of the travel time RUN1 (1, 1, 2). This predicted waiting time WT (1, 2, up) is recorded in the second floor column in the upward direction (UP).

-Upstairs 3rd floor-
The unit will run up from the first floor (lobby floor) to the third floor. In this case, since the number of moving floors is the second floor and the travel distance is shorter than the target travel distance, it is not possible to travel at a higher speed. Therefore, the column of the first floor and the third floor of the destination floor in the normal travel time table Tro is referred to obtain 5 seconds of the travel time RUN1 (1, 1, 3), and the predicted waiting time WT (1, 3 , Up) is 5 seconds of the travel time RUN1 (1, 1, 3). This predicted waiting time WT (1, 3, up) is recorded in the column on the third floor in the upward direction (UP).

-Upstairs 4th floor-
The unit will run up from the first floor (lobby floor) to the fourth floor. In this case, the number of moving floors is the third floor, the travel distance is longer than the target travel distance, and the current boarding rate is 50%, which is within the target boarding rate range, so it is possible to travel at a higher speed. . In that case, since the departure floor is the lobby floor, the number of moving floors in the first speed-up traveling time table Tra is referred to the third floor column, and the traveling time RUN2A (1, 1, 4) of 6 seconds is calculated. As a result, the predicted waiting time WT (1, 4, up) is 6 seconds of the travel time RUN2A (1, 1, 4). This predicted waiting time WT (1, 4, up) is recorded in the column on the fourth floor in the upward direction (UP). The shaded column in the pre-provisional prediction waiting time table Tw1 indicates that the first speed-up travel time table Tra or the second speed-up travel time table Trb is referenced.

-Upstairs 5-
When the elevator travels from the first floor (lobby floor) to the fifth floor, it stops at the fourth floor for a predetermined stop time stop_t in order to process an existing destination floor call for the fourth floor. The predetermined stop time stop_t is set to 1.5 seconds in this example. By the time the elevator 40 arrives on the fourth floor, 6 seconds of the above-described predicted waiting time WT (1, 4, up) on the fourth floor has elapsed. In ascending traveling from the fourth floor to the fifth floor, the number of moving floors is the first floor, and the traveling distance is shorter than the target traveling distance. For this reason, in the normal travel time table Tro, the column of the departure floor is the 4th floor and the destination floor is the 5th floor, and 2 seconds of the travel time RUN1 (1, 4, 5) is obtained.

(Formula 1)
WT (1,5, up) = WT (1,4, up) + stop_t + RUN1 (1,4,5)
= 6 + 1.5 + 2 = 9.5

  In addition, since there is no destination floor call in the upper direction on the 6th floor of the top floor, only the prediction waiting time on the 6th floor exists in the downward direction. In addition, since there is no destination floor call in the downward direction on the first floor of the lowest floor, only the prediction waiting time on the first floor relates to the upward direction.

-6th floor-
When the unit goes up from the first floor (lobby floor) to the sixth floor, it stops for a predetermined stop time stop_t on the fourth and fifth floors in order to process the existing destination floor calls for the fourth and fifth floors. . Before the elevator 40 arrives at the fifth floor, 9.5 seconds of the estimated waiting time WT (1, 5, up) at the fifth floor described above have elapsed. In climbing from the 5th floor to the 6th floor, the number of moving floors is 1st floor, and the travel distance is shorter than the target travel distance. Therefore, the column of the departure floor of the normal travel time table Tro is the fifth floor and the destination floor is the sixth floor, and 2 seconds of the travel time RUN1 (1, 5, 6) is obtained. The predicted waiting time WT (1, 6, down) is calculated from the 5th floor to the predicted waiting time WT (1, 5, up), the predetermined stop time stop_t, as shown in the following formula 2. 13 seconds which is the total value of the travel time RUN1 (1, 5, 6). This predicted waiting time WT (1, 6, down) is recorded in the column on the sixth floor in the downward direction (DOWN).

In descending travel from the 6th floor to the 4th floor, the number of moving floors is 2nd floor, and the travel distance is shorter than the target travel distance. Therefore, the column of the departure floor of the normal travel time table Tro is 6th floor and the destination floor is 4th floor is referred to, and 4 seconds of travel time RUN1 (1, 6, 4) is obtained. The predicted waiting time WT (1, 4, down) is calculated from the 6th floor to the 4th floor, as shown in the following formula 4, the predicted waiting time WT (1, 6, down) on the 6th floor, the predetermined stop time stop_t, 18.5 seconds, which is the total value of the travel time RUN1 (1, 6, 4). This predicted waiting time WT (1, 4, down) is recorded in the fourth floor column in the downward direction (DOWN).

The predicted waiting time WT (1, 3, down) is calculated from the sixth floor to the third floor, as shown in the following formula 5, the predicted waiting time WT (1, 6, down) on the sixth floor, the predetermined stop time stop_t, 19.5 seconds which is the total value of the travel time RUN2B (1, 6, 3). The predicted waiting time WT (1, 3, down) is recorded in the third floor column in the downward direction (DOWN).

(Formula 5)
WT (1,3, down) = WT (1,6, down) + stop_t + RUN2B (1,6,3)
= 13 + 1.5 + 5 = 19.5

2-4-2. Specific Example of Creation of Temporary Allocation Predictive Waiting Time Table A specific example of creating the post temporary allocation predicted waiting time table Tw2 in FIG. 6B will be described. In this example, as described above with reference to FIG. 7B, a case will be described in which a destination floor call is newly assigned in the upward direction on the third floor and the destination floor is the fifth floor.

  In the case where a new upward destination floor call occurs on the first floor, the second floor, and the third floor, the prediction waiting time before temporary allocation WT (1,1, up), WT (1,2, up), WT ( 1, 3, up). Note that WT (1, 1, up) is 0 seconds, WT (1, 2, up) is 3 seconds, and WT (1, 3, up) is 5 seconds.

-Upstairs 4th floor-
When the No. 1 machine goes up from the first floor (lobby floor) to the fourth floor, it stops at the third floor for a predetermined stop time stop_t in order to process a destination floor call for the temporarily allocated third floor. By the time the elevator 40 arrives at the third floor, 5 seconds of the above-described predicted waiting time WT (1, 3, up) at the third floor has elapsed. In ascending traveling from the third floor to the fourth floor, the number of moving floors is the first floor, and the traveling distance is shorter than the target traveling distance, so the traveling at an increased speed cannot be performed. For this reason, in the normal travel time table Tro, the column of the departure floor is the third floor and the destination floor is the fourth floor is referred to, and 2 seconds of the travel time RUN1 (1, 3, 4) is obtained. The predicted waiting time WT (1, 1, 4) is the predicted waiting time WT (1, 3, up) on the third floor, the predetermined stop time stop_t, and from the third floor to the fourth floor, as shown in Equation 7 below. This is 8.5 seconds which is the total value of the travel time RUN1 (1, 3, 4). This predicted waiting time WT (1, 4, up) is recorded in the column on the fourth floor in the upward direction (UP).

(Formula 7)
WT (1,4, up) = WT (1,3, up) + stop_t + RUN1 (1,3,4)
= 5 + 1.5 + 2 = 8.5

-Upstairs 5-
When the relevant unit goes up from the 1st floor (lobby floor) to the 5th floor, the destination floor call for the temporarily assigned 3rd floor and the destination floor call for the existing 4th floor are processed, so that each of the 3rd floor and 4th floor Stop for stop time stop_t. By the time the elevator 40 arrives at the fifth floor, 8.5 seconds of the predicted waiting time WT (1, 4, up) at the fourth floor described above has elapsed. In ascending traveling from the fourth floor to the fifth floor, the number of moving floors is the first floor, and the traveling distance is shorter than the target traveling distance. For this reason, in the normal travel time table Tro, the column of the departure floor is the 4th floor and the destination floor is the 5th floor, and 2 seconds of the travel time RUN1 (1, 4, 5) is obtained. The predicted waiting time WT (1, 5, up) is the predicted waiting time WT (1, 4, up) on the 4th floor, the predetermined stop time stop_t, and the 4th to 5th floors as shown in the following formula 8. This is 12 seconds which is the total value of the travel time RUN1 (1, 4, 5). This predicted waiting time WT (1, 5, up) is recorded in the column on the fifth floor in the upward direction (UP).

(Formula 8)
WT (1,5, up) = WT (1,4, up) + stop_t + RUN1 (1,4,5)
= 8.5 + 1.5 + 2 = 12

-Down 6th floor, 5th floor, 4th floor, 3rd floor, 2nd floor-
Regarding the downward direction from the 6th floor, it is out of the travel range of the temporary floor call from the 3rd floor to the 5th floor, and there is no new stop due to the temporary floor call from the 3rd floor to the 5th floor. . Therefore, the predicted waiting time before temporary allocation on the sixth floor, the fifth floor, the fourth floor, the third floor, and the second floor in the downward direction is the predicted waiting time before temporary allocation WT (1, 6, down), WT (1, 5, down), WT (1, 4, down), WT (1, 3, down), and WT (1, 2, down). In addition, the value of the estimated waiting time after temporary allocation WT (1, 5, up) is a value obtained by adding 2.5 seconds to the value of the predicted waiting time before temporary allocation WT (1, 5, up). Therefore, after temporary allocation, the forecast waiting time before temporary allocation on the sixth floor, the fifth floor, the fourth floor, the third floor, and the second floor in the downward direction is the predicted waiting time before temporary allocation WT (1, 6, down), WT. This is a value obtained by adding 2.5 seconds to (1,5, down), WT (1,4, down), WT (1,3, down), and WT (1,2, down). That is, as shown in Equations 9 to 13, WT (1, 6, down) is 15.5 seconds, WT (1, 5, down) is 19 seconds, WT (1, 4, down) is 21 seconds, WT (1, 3, down) is 22 seconds, and WT (1, 2, down) is 23 seconds.

(Formula 9)
WT (1,6, down) = WT (1,5, up) + stop_t + RUN1 (1,5,6)
= 12 + 1.5 + 2 = 15.5

(Formula 10)
WT (1,5, down) = WT (1,6, down) + stop_t + RUN1 (1,6,5)
= 15.5 + 1.5 + 2 = 19

(Formula 11)
WT (1,4, down) = WT (1,6, down) + stop_t + RUN1 (1,6,4)
= 15.5 + 1.5 + 4 = 21

(Formula 12)
WT (1,3, down) = WT (1,6, down) + stop_t + RUN2B (1,6,3)
= 15.5 + 1.5 + 5 = 22

(Formula 13)
WT (1,2, down) = WT (1,6, down) + stop_t + RUN2B (1,6,2)
= 15.5 + 1.5 + 6 = 23

2-5. Main Actions and Effects of Elevator County Management System of this Embodiment In this embodiment, as described above, the estimated waiting time WT (i, fc, vc) until arrival at each floor from the current position is increased in speed. The travel section that satisfies the condition is obtained based on the travel time based on the actual travel time recorded in the speed-up travel time table Tr, and the travel section that does not satisfy the speed-up travel condition is recorded in the normal travel time table Tro. It is obtained based on the travel time based on the actual travel time. Therefore, the predicted waiting time WT (i, fc, vc) from the current position to the arrival of each floor can be obtained with high accuracy according to the actual installation state of the elevator 40 at the site, actual traveling conditions, and the like.

  Further, the group management control device 10 automatically measures the actual traveling time between floors during speed-up traveling and normal traveling, and based on the measured actual traveling time, the speed-up traveling time table Tr and the normal traveling are measured. A time table Tro is created. Therefore, it is not necessary to manually create the speed-up traveling time table Tr and the normal traveling time table Tro, and the creation of each table becomes efficient.

  In addition, after the created speed-up travel time table Tr and normal travel time table Tro are created, the actual travel time between floors during speed-up travel and normal travel is measured and measured when each table is created. Based on both the actual travel time and the actual travel time measured after the creation, the speed-up travel time table Tr and the normal travel time table Tro are updated. Therefore, it is not necessary to manually update the speed-up traveling time table Tr and the normal traveling time table Tro, and the updating of each table becomes efficient. Further, the speed-up traveling time table Tr and the normal traveling time table Tro can be automatically maintained in the latest state.

  Here, the traveling time of each elevator 40 may vary due to individual differences of the elevator 40, aging deterioration, and the like. However, in the present embodiment, the predicted waiting time WT (i, fc, vc) is obtained for each elevator 40 based on the speed-up traveling time table Tr and the normal traveling time table Tro corresponding to each elevator 40. Therefore, even when there are individual differences among the plurality of elevators 40, aging deterioration, or the like, it is possible to obtain an accurate prediction waiting time.

  Also, especially after starting actual operation locally, the opportunity for speeding up is generally less than the opportunity for normal driving. For this reason, the update frequency of the travel time during speed-up travel is reduced. In order to cope with this, in the present embodiment, the traveling time between floors is recorded in correspondence with the number of moving floors in the speed-up traveling time table Tr. The number of patterns of the moving floor number is smaller than the number of combination patterns of the departure floor and the destination floor. Therefore, it is possible to create a record and update travel time table with a smaller number of travels and update it more frequently than when recording travel time corresponding to the combination of the departure floor and destination floor. Can do.

  In the present embodiment, the estimated waiting time WT (i, fc, vc) until each elevator 40 arrives at each floor from the current position responds only to the destination floor call that has already been assigned to each elevator 40. (First case) and the case of responding to both the already assigned destination floor call and the new destination floor call (second case). Further, the new destination floor call is sent to any one of the plurality of elevators 40 by the predicted waiting time WT (i, fc, vc) in the first case and the predicted waiting time WT (2 in the second case). i, fc, vc). Therefore, a new destination floor call is sent to any one of the plurality of elevators 40 with the predicted waiting time WT (i, fc, vc) in the first case and the predicted waiting time WT (in the second case). i, fc, vc) and more appropriately. Therefore, the transport efficiency by the plurality of elevators 40 can be further improved.

3. Summary The elevator group management system according to the present embodiment causes the elevator 40 to travel at a speed higher than the rated speed in a traveling section that satisfies the speed-up traveling condition, and does not satisfy the speed-up traveling condition. , Normal traveling is performed in which the elevator 40 travels at the rated speed.
The elevator group management system includes a destination floor registration device 20 for a user to register a destination floor call indicating a desired destination floor, and a destination floor call registered by the destination floor registration device 20 for a plurality of elevators 40. A group management control device 10 (control device) assigned to any one of the elevators based on a predicted waiting time WT (i, fc, vc) until each elevator 40 arrives at each floor from the current position is provided.
The group management control device 10
Speed-up travel time table Tr that records travel time based on the actual travel time between floors during speed-up travel, and normal travel time table Tro that records travel time based on the actual travel time between floors during normal travel And memorize.
The group management control device 10
When a new destination floor call is registered in the destination floor registration device 20, an estimated waiting time WT (i, fc, vc) until each elevator 40 arrives at each floor from the current position is calculated.
The travel section that satisfies the speed-up travel condition is obtained based on the travel time recorded in the speed-up travel time table Tr,
A travel section that does not satisfy the speed-up travel condition is obtained based on the travel time recorded in the normal travel time table Tro.

  Thus, the estimated waiting time WT (i, fc, vc) from the current position to the arrival of each floor is the actual travel time recorded in the speed-up travel time table Tr for the travel section that satisfies the speed-up travel condition. The travel section that is obtained based on the travel time based on the actual travel time is recorded in the normal travel time table Tro for the travel section that does not satisfy the speed-up travel condition. Therefore, the predicted waiting time WT (i, fc, vc) from the current position to the arrival at each floor can be accurately obtained according to the actual installation state of the elevator 40, the actual traveling conditions, and the like.

In this embodiment,
The group management control device 10 measures the actual traveling time between floors during speed-up traveling and normal traveling, and creates the speed-up traveling time table Tr and the normal traveling time table Tro based on the measured actual traveling time. To do.

  Thus, the group management control device 10 automatically measures the actual traveling time between the floors during the speed-up traveling and the normal traveling, and based on the measured actual traveling time, the speed-up traveling time table Tr and the normal traveling are measured. A time table Tro can be created.

In this embodiment,
The group management control device 10 measures the actual travel time between floors during speed-up travel and normal travel after creating the created speed-up travel time table Tr and normal travel time table Tro, and creates each table. The speed-up travel time table Tr and the normal travel time table Tro are updated based on both the actual travel time measured sometimes and the actual travel time measured after the creation.

  Thereby, it is not necessary to manually update the speed-up traveling time table Tr and the normal traveling time table Tro, and the updating of each table becomes efficient. Further, the speed-up traveling time table Tr and the normal traveling time table Tro can be automatically maintained in the latest state.

In this embodiment,
The group management control device 10
A speed-up traveling time table Tr and a normal traveling time table Tro are created for each of the plurality of elevators 40,
The predicted waiting time WT (i, fc, vc) for each elevator 40 is obtained based on the speed-up traveling time table Tr and the normal traveling time table Tro corresponding to each elevator 40.

  Thus, the predicted waiting time WT (i, fc, vc) is obtained for each elevator 40 based on the speed-up traveling time table Tr and the normal traveling time table Tro corresponding to each elevator 40. Here, the traveling time of each elevator 40 may vary due to individual differences of the elevator 40, aging deterioration, and the like. According to this configuration, an accurate prediction waiting time can be obtained even in such a case.

In this embodiment,
In the normal travel time table Tro and the speed up travel time table Tr, the travel time between floors is recorded in a matrix as a combination of the departure floor and the destination floor,
The group management control device 10
For the travel section that satisfies the speed-up travel condition, the travel time between floors is obtained by referring to the speed-up travel time table Tr based on the departure floor and the destination floor,
For the travel section that does not satisfy the speed-up travel condition, the travel time between floors is obtained by referring to the normal travel time table Tro based on the departure floor and the destination floor.

  As a result, the travel time between floors during normal travel and speed-up travel can be obtained accurately based on the departure floor and the destination floor.

In this embodiment,
In at least the speed-up travel time table Tr of the normal travel time table Tro and the speed-up travel time table Tr, the travel time between floors is recorded corresponding to the number of moving floors.

  As a result, it is possible to obtain the travel time between floors during at least speed-up travel during normal travel and speed-up travel based on the number of moving floors. The number of patterns of the moving floor number is usually smaller than the number of combination patterns of the departure floor and the destination floor. Therefore, the travel time table can be created with a small number of travels. In addition, when a configuration for updating is employed, the update frequency can be increased. In particular, after starting actual operation locally, the speed-up driving opportunity is generally less than the normal driving opportunity. For this reason, the update frequency of the travel time during speed-up travel is reduced. Even in such a case, it is possible to increase the update frequency and improve the accuracy of the calculated predicted waiting time by recording and updating the traveling time between floors in correspondence with the number of moving floors. .

In this embodiment,
The group management control device 10
In the first case where the estimated waiting time WT (i, fc, vc) until each elevator 40 arrives at each floor from the current position is responded only to the destination floor call already assigned to each elevator 40, and already assigned For each of the second case responding to both the destination floor call being made and the new destination floor call,
The predicted waiting time WT (i, fc, vc) in the first case and the predicted waiting time WT (i, fc, vc) in the second case are set in any one of the plurality of elevators 40. Assign based on.

  As a result, a new destination floor call is sent to any one of the plurality of elevators 40 with the predicted waiting time WT (i, fc, vc) in the first case and the predicted waiting time WT in the second case. (I, fc, vc) can be assigned more appropriately based on both. Therefore, the transportation efficiency by the plurality of elevators 40 is further improved.

In this embodiment,
The speed-up travel condition is that the travel distance of the travel section is equal to or greater than the target travel distance, and the boarding rate of the travel section is within the target boarding rate range.

  As a result, when the travel distance of the travel section is equal to or greater than the target travel distance, and the boarding rate of the travel section is within the target boarding rate range, it is possible to travel at a higher speed.

The elevator group management control device 10 (control device) of the present embodiment is
In the travel section that satisfies the speed-up travel condition, the speed-up travel is performed in which the elevator 40 travels at a speed faster than the rated speed.
The group management control device 10
Before starting actual operation (at a predetermined time), each of the traveling sections satisfying the speed-up traveling condition among the traveling sections of all combinations in which one floor of the plurality of floors is the departure floor and the other floor is the destination floor. The actual travel time is measured by speeding up the vehicle 40, and a speed-up travel time table Tr recording the travel time based on the measured actual travel time is created and stored.

  As a result, the group traveling control device 10 can automatically measure the actual traveling time between floors during speed-up traveling, and create the speed-up traveling time table Tr based on the measured actual traveling time.

In this embodiment,
The group management control device 10
When the elevator 40 travels between the departure floor and the destination floor and the actual traveling time is measured, the number of moving floors between the departure floor and the destination floor is obtained,
The travel time based on the measured actual travel time is recorded in association with the obtained number of moving floors.

  Thereby, as described above, the speed-up travel time table Tr can be created with a small number of travels. In addition, when the configuration for updating the speed-up travel time table Tr is employed, the update frequency can be increased.

In this embodiment,
The height of the lobby floor (predetermined floor) of the multiple floors is different from the height of other floors,
The speed-up travel time table Tr includes a first speed-up travel time table Tra in which travel time based on the actual travel time of the travel section including the lobby floor is recorded, and travel based on the actual travel time of the travel section not including the lobby floor. A second speed-up travel time table Trb in which time is recorded,
The group management control device 10
Determine whether the driving section that satisfies the speedup driving condition includes the lobby floor,
When the lobby floor is included, the travel time based on the measured actual travel time is recorded in the first speed-up travel time table Tra,
When the lobby floor is not included, the travel time based on the measured actual travel time is recorded in the second speed-up travel time table Trb.

  Here, the number of patterns of moving floors is usually a combination of the departure floor and the destination floor, even if the height of the lobby floor (predetermined floor) of the multiple floors is different from the floor height of other floors. Less than the number of patterns. Therefore, the speed-up travel time table Tr can be created with a small number of travels. In addition, when the configuration for updating the speed-up travel time table Tr is employed, the update frequency can be increased. The predetermined floor is not limited to the lobby floor. The predetermined floor may be a floor other than the lobby floor.

In this embodiment,
After creating the speed-up travel time table Tr, the group management control device 10 measures the actual travel time between floors during speed-up travel, and the actual travel time measured when creating the speed-up travel time table and after creation The speed-up travel time table Tr is updated based on both the measured actual travel time.

  Thereby, it is not necessary to manually update the speed-up traveling time table Tr, and the updating of each table can be made efficient. Further, the speed-up traveling time table Tr can be automatically maintained in the latest state.

In this embodiment,
The group management control device 10
Before the actual operation is started (at a predetermined time), the normal traveling in which the elevator 40 is driven at the rated speed is performed for all combinations of traveling sections in which one floor of the plurality of floors is a departure floor and the other floor is a destination floor. The actual travel time is measured and the normal travel time table Tro in which the travel time based on the measured actual travel time is recorded is created and stored.

  Thereby, the actual traveling time between floors during normal traveling can be automatically measured by the group management control device 10, and the normal traveling time table Tro can be created based on the measured actual traveling time.

In this embodiment,
The predetermined time is a predetermined time before the elevator 40 is put into actual operation.

  Thus, the speed-up traveling time table Tr and the normal traveling time table Tro can be created before the elevator 40 is put into actual operation. Therefore, it is possible to control the elevator operation with high accuracy from the start of actual operation.

(Embodiment 2)
In the first embodiment, the speed-up travel time table Tr records the travel time between floors during speed-up travel in association with the number of moving floors. However, in the present invention, the travel time between floors during speed-up travel may be recorded in correspondence with the travel distance. This will be specifically described below.

  FIG. 13 is a diagram showing a speed-up traveling time table Trd in the elevator group management system according to the second embodiment. In the speed-up travel time table Trd, the travel time between floors is recorded corresponding to the travel distance. For example, when the moving distance is 12 m, 15 m, 16 m, 19 m, and 23 m, the traveling times between the floors are 5 seconds, 6 seconds, 6 seconds, 7 seconds, and 8 seconds, respectively.

  FIG. 14 is a functional block diagram illustrating functions of the group management control device of the elevator group management system according to the second embodiment. In the present embodiment, the traveling time table creation unit 10C stores a speed-up traveling time table Trd, a normal traveling time table Tro, and a floor height table Tf. The normal travel time table Tro is the same as that of the first embodiment.

  FIG. 15 is a flowchart illustrating a creation operation of the speed-up traveling time table Trd in the elevator group management system according to the second embodiment. In steps S31 to S37 and S41 to S45 in this flowchart, the same processing as steps S31 to S37 and S41 to S45 in FIG. 10 is performed. That is, only the processes of steps S46 and S47 are different. For this reason, the processing in steps S46 and S47 will be mainly described.

  That is, when the traveling time is measured in step S37, the group management control device 10 acquires the height LSF of the departure floor and the height LDF of the destination floor from the floor height table Tf (S46).

  FIG. 16 is a diagram illustrating an example of a floor height table Tf in the elevator group management system according to the second embodiment. In this example, the heights (m) of the first floor, the second floor, the third floor, the fourth floor, the fifth floor, and the sixth floor are 0 m, 7 m, 11 m, 15 m, 19 m, and 23 m, respectively. The height of each floor is a height based on 0 m of the height of the first floor.

  The group management control device 10 records the measured travel time in the corresponding travel distance column in the speed increase travel time table Trd of the i-th car (S47). The corresponding movement distance is | LSF−LDF |, that is, the absolute value of a value obtained by subtracting the value of the destination floor height LDF from the value of the departure floor height LSF. When step S47 is executed, the group management control device 10 executes the processing after step S41 as in the first embodiment.

  Here, in the process of sequentially executing the processing according to this flowchart for all departure floors and all destination floors, the movement distance | LSF-LDF | obtained in this step S47 is the same as the movement distance obtained so far. It may become. For example, when the departure floor SF is the second floor and the destination floor DF is the fifth floor, when the departure floor SF is the third floor and the destination floor DF is the sixth floor, when the departure floor SF is the sixth floor and the destination floor DF is the third floor, When the departure floor SF is the fifth floor and the destination floor DF is the second floor, the movement distance | LSF−LDF | is 12 m in both cases. When the departure floor SF is the second floor and the destination floor DF is the sixth floor, and when the departure floor SF is the sixth floor and the destination floor DF is the second floor, the travel distance | LSF−LDF | In these cases, the group management control device 10 performs the following processing.

  That is, the group management control device 10 determines whether or not the travel time is recorded in the column corresponding to the obtained travel distance | LSF-LDF | When the travel time is not recorded in the column corresponding to the calculated travel distance, the group management control device 10 sets the travel time measured this time to the travel distance determined for the travel section measured this time. To record. On the other hand, when the travel time is recorded in the column corresponding to the obtained travel distance | LSF-LDF |, the group management control device 10 determines the travel time already recorded and the newly measured travel time. Is averaged based on the number of updates so far to obtain an average value of travel time, and the obtained travel time is recorded in a column corresponding to the travel distance of the current travel section. That is, the group management control device 10 updates the travel time in the column corresponding to the travel distance of the current travel section. Thereby, the precision of the traveling time recorded in the speed-up traveling time table Trd can be improved. The number of updates may be stored in association with the movement distance (in the column corresponding to) in this step. Instead of determining whether the travel time is recorded in the column corresponding to the obtained travel distance | LSF-LDF |, the group management control device 10 corresponds to the obtained travel distance | LSF-LDF |. It may be determined whether a default value (for example, “0”) is recorded in the column.

As described above, in the present embodiment,
In the speed-up travel time table Trd out of the normal travel time table Tro and the speed-up travel time table Tr, the travel time between floors is recorded corresponding to the travel distance.

In this embodiment,
The group management control device 10
When the elevator 40 is driven between the departure floor and the destination floor and the actual traveling time is measured, the distance between the moving floor between the departure floor and the destination floor is obtained,
The travel time based on the measured actual travel time is recorded in association with the obtained distance between the moving floors.

  According to the present embodiment, as in the first embodiment, it is possible to improve the accuracy of the calculated predicted waiting time by increasing the update frequency of the travel time in each column of the speed-up travel time table Tr. Also, depending on the building, the floor height may vary from floor to floor, but even in such a case, it is possible to record variously by recording according to the moving distance instead of the number of moving floors as in this embodiment. It is possible to cope with a complex building structure with one speed-up traveling time table.

(Embodiment 3)
In the first embodiment, the speed-up travel time table Tr records the travel time between floors during speed-up travel in association with the number of moving floors. However, in the present invention, the traveling time between floors during speed-up traveling may be recorded in a matrix according to the combination of the departure floor and the destination floor, as in the normal traveling time table of the first embodiment. Note that since the travel time is not measured for the section where the speed-up traveling is impossible, the travel time is recorded only in the column corresponding to the section where the speed-up travel time table can be traveled. In this case, instead of the processes of S38, S39, and S40 in the flowchart of FIG. 10, the same process as step S17 of the flowchart of FIG. 9 may be performed. In this case, what is necessary is just to read the normal time table of step S17 as a speed-up traveling time table. In the present embodiment, for example, when the operation frequency of the elevator 40 is high enough that the update frequency of the speed-up traveling time table Tr is sufficiently obtained, the accurate prediction waiting time according to the combination of the departure floor and the destination floor is set. Can be sought.

(Embodiment 4)
In the first embodiment, the normal travel time table Tro records the travel time between floors during normal travel in a matrix according to the combination of the departure floor and the destination floor. However, in the present invention, the traveling time between floors during normal traveling may be recorded corresponding to the number of moving floors, as in the speed-up traveling time table in the first embodiment. In this case, as the normal travel time table, as in the first embodiment, the first normal travel time table that records the travel time between floors when the departure floor or the destination floor is the lobby floor, and the departure floor and the destination floor are What is necessary is just to provide the 2nd normal travel time table which recorded the travel time between floors when neither is a lobby floor. Further, instead of the processing in step S17 in the flowchart of FIG. 9, the same processing as S38, S39, and S40 in the flowchart of FIG. 10 may be performed. In this case, the first speed up travel time table in step S39 may be replaced with the first normal travel time table, and the second speed up travel time table in step S40 may be replaced with the second normal travel time table.

(Embodiment 5)
In the first embodiment, the normal travel time table Tro records the travel time between floors during normal travel in a matrix form corresponding to the combination of the departure floor and the destination floor. However, in the present invention, the normal travel time table Tro may be recorded in correspondence with the travel distance, like the speed-up travel time table in the second embodiment. In this case, as the normal travel time table, a normal travel time table that records the travel time between floors when the departure floor or the destination floor is the lobby floor may be provided as in the first embodiment. Further, instead of the processing in step S17 in the flowchart of FIG. 9, the same processing as S46 and S47 in the flowchart of FIG. 15 may be performed. In this case, the speed-up travel time table in step S47 may be read as a normal travel time table.

(Embodiment 6)
In the first embodiment, a travel time table is created for each elevator 40. However, in the present invention,
The group management control device 10
A travel time table for a predetermined elevator 40 and a travel time table for other elevators 40 are created as the travel time table,
For the predetermined elevator 40, the predicted waiting time is obtained based on the travel time table for the predetermined elevator 40,
For the other elevators 40, the predicted waiting time may be obtained based on the travel time table for the other elevators 40.

  Thus, the predicted waiting time for the predetermined elevator 40 is obtained based on the traveling time table for the predetermined elevator 40, and the predicted waiting time for the other elevators 40 is calculated in the traveling time table for the other elevators 40. It will be determined based on. Here, as for an elevator 40 among the plurality of elevators 40, for example, there are cases where the conditions for running the elevator 40 and opening / closing the door are different for the physically handicapped. According to this configuration, an appropriate and accurate prediction waiting time can be obtained even in such a case.

(Embodiment 7)
In the first embodiment, a normal travel time table Tro, a first speed up travel time table Tra, and a second speed up travel time table Trb are created for each elevator 40. However, in the present invention, the normal travel time table Tro, the first speed up travel time table Tra, and the second speed up travel time table Trb may be shared by all the elevators 40, respectively. In this case, when the travel time measured by each elevator is recorded in a common table, the averaging process described in the first embodiment may be performed. Thereby, control can be simplified. In particular, when the specifications of all the elevators 40 are common, there is little difference in travel time between the elevators 40, so that sufficient accuracy can be obtained.
