Description

Embodiments of the present invention relate to an operation control method for a group management elevator and a group management control device.

When a building shakes due to the influence of a long-period earthquake or strong wind, long elevators (main ropes connected to the car, compensating ropes, tail cords, etc.) installed in the building resonate with the building shakes. It may shake a lot. Therefore, it is proposed to estimate the shake amount of a long object by real-time simulation based on the size and duration of the building shake and the position of the car, and to perform control operation according to the estimated shake amount of the long object. Has been done.

When the amount of vibration of the long object reaches the upper limit level of contact with the equipment in the hoistway or the hoistway wall, the elevator stops its operation. In this case, in order to ensure the safety of the elevator, it is necessary to perform maintenance work such as inspections and repairs by maintenance personnel after the building shakes have settled. For this reason, if the amount of shake of long objects reaches the upper limit level in all elevators that make up the group-controlled elevator, the service cannot be restarted immediately even if the building shake has stopped, and the service will be stopped for a long time. Will be forced to. Against this background, there is a demand for at least one elevator to be ready for operation after the building sway has subsided.

Hereinafter, specific embodiments of an operation control method for a group management elevator and a group management control device to which the present invention is applied will be described in detail with reference to the drawings.

<First Embodiment>
FIG. 1 is a schematic configuration diagram of each elevator that constitutes a group management elevator. As shown in FIG. 1, each elevator constituting the group management elevator is moved up and down the car 2 in a hoistway 1 provided in a building having a plurality of floors so that the car 3 can be moved from a hall 3 on a certain floor. It is a transportation means for transporting passengers who boarded the vehicle to the hall 3 on another floor. The car 2 is connected to a counterweight 5 via a main rope 4. Then, the hoisting machine 6 is driven to feed the main rope 4, whereby the car 2 moves up and down in the hoistway 1 while maintaining balance with the counterweight 5.

At the bottom of the hoistway 1, a compensating sheave 7 and a shock absorber (not shown) are provided. The compensating sheave 7 is wound around a compensating rope 8 whose both ends are balanced with the lower part of the car 2 and are connected to the lower part of the weight 5. The compensating rope 8 has a role of canceling a change in the weight balance of the main rope 4 caused by the car 2 moving up and down in the hoistway 1.

The hoisting machine 6 described above is provided in the machine room 9 above the hoistway 1. In the machine room 9, in addition to the hoisting machine 6, a unit control device 10 for each elevator that constitutes the group management elevator, a group management control device 20, and a building shake detector 11 such as an acceleration sensor that detects a building shake. And are provided. The hoisting machine 6, the single control device 10, the group management control device 20, the building shake sensor 11 and the like may be arranged in the hoistway 1 and the machine room 9 may not be provided.

The unit controller 10 includes a microcomputer having a CPU, a ROM, a RAM, etc., and registers car calls, controls movement of the car 2 according to car calls and hall calls (drive control of the hoisting machine 6), Controls the operation of the elevator itself, such as controlling the opening and closing of the car 2 door. The unit control device 10 and the car 2 are connected by a tail cord 12, through which power is supplied to the car 2 and various signals are exchanged.

The group management control device 20 includes a microcomputer provided with a CPU, a ROM, a RAM, and the like, and allocates a hall call to the elevators (group management control) while monitoring the operating states of a plurality of elevators. The group management control device 20 is connected to the unit control device 10 of each elevator that constitutes the group management elevator. A building shake sensor 11 is also connected to the group management control device 20.

FIG. 2 is a schematic configuration diagram of the group management elevator system according to the present embodiment. At the hall 3 on each floor of the building where the group management elevator is installed, as shown in FIG. 2, a hall door 13 that opens and closes in association with the doors of the car 2 corresponding to each elevator that constitutes the group management elevator. And a hall indicator 14 for displaying various information. In addition, the hall 3 on each floor is provided with a hall operation panel 15 that is operated by passengers to call the hall. The hall operating panel 15 and the hall indicator 14 are connected to the group management control device 20. In the example shown in FIG. 2, the number of elevators forming the group management elevator is three, but the number of elevators is arbitrary.

The group management elevator according to this embodiment has a distributed standby function. The distributed standby function is to disperse the elevator cars 2 whose calls have been answered in a distributed standby zone consisting of multiple zones that are distributed over the lower and upper floors of the building. It is a function to make it stand by. When the car 2 is not waiting in at least one of the plurality of zones forming the distributed waiting zone, the car 2 of the elevator that has completed the response to the call is not waiting on the spot but is vacant ( Go to the zone (other car 2 is not waiting) and wait there until a new hall call is assigned. In the distributed waiting function, when a hall call is made on a certain floor, the hall call can be assigned to the car 2 waiting in the zone close to the floor to reduce the waiting time at the hall.

Here, in the group management elevator according to the present embodiment, in particular, as a distributed standby zone composed of a plurality of zones in which the cars 2 are distributed standby, a normal operation distributed standby zone (first distributed standby zone) and a control operation Two types of distributed standby zones are defined: a time distributed standby zone (second distributed standby zone). Then, as will be described later, when the operation mode of the group control elevator is changed from normal operation to control operation, the distributed standby zone is switched from the normal operation distributed standby zone to the control operation distributed standby zone.

When a building shake occurs due to a long-period earthquake or strong wind, a long object (main rope 4, compensating rope 8, tail cord 12, etc.) connected to the car 2 may resonate with the building shake. The degree of resonance of the long object differs depending on the floor on which the car 2 is located. The amount of shake of a long object due to the shaking of the building can be estimated from the size of the shaking of the building, the duration for which the shaking of the building continues for that size, and the floor on which the car 2 is located. Therefore, in the present embodiment, for each floor of the building in which the group control elevator is installed, the shake amount of the long object when the car 2 is on that floor is set for each combination of the size of the building shake and the duration time. The group management control device 20 holds the estimation result as a shake amount data table 31. The shake amount data table 31 is the same as the data table used in the real-time simulation disclosed in Patent Document 1.

In addition, in the present embodiment, a resonance level indicating the degree to which a long object connected to the car 2 resonates with the shaking of the building is set for each floor of the building where the group control elevator is installed. The resonance level of each floor is, for example, by using the above-mentioned shake amount data table 31, when the building shake of a predetermined size continues for a predetermined time, how much the shake amount of the long object becomes on each floor. It can be set by confirming in advance.

Further, in the present embodiment, the above-described normal operation distributed standby zone and the control operation distributed standby zone are determined in advance. And information indicating the resonance level of each floor of the building, and information indicating which floor of the building each of the plurality of zones forming the distributed standby zone during normal operation and the multiple zones forming the distributed standby zone during control operation Is stored as building data 32 in the group management control device 20.

An example of the building data 32 held by the group management control device 20 is shown in FIG. The building data 32 shown in FIG. 3 is an example of a case where the first to 20th floors of the building are serviced by the group management elevator and the distributed standby zone is composed of three zones. Resonance levels of each floor up to the floor are shown in three levels of Level 1 to Level 3, and floors set in three zones (zones A, B, and C) that constitute a dispersion standby zone during normal operation, The floors set in three zones (zones A, B, and C) forming the distributed standby zone during control operation are shown. As can be seen from the example of FIG. 3, the three zones forming the normal operation distributed standby zone are evenly distributed from the lower floors to the upper floors of the building. On the other hand, the three zones that form the distributed standby zone during control operation are set from the viewpoint that the long object connected to the car 2 does not easily resonate with the shaking of the building. Of the three zones forming the distributed standby zone during control operation, the zone in which a long object hardly resonates with building vibration (zone B in the example of FIG. 3) is called the "priority standby zone".

In the group management elevator system according to the present embodiment, building shake is detected by the building shake detector 11, and the shake amount of at least one elevator long object is determined based on the shake amount data table 31 described above to an upper limit level (for example, When it is predicted that the level of contact with the equipment in the hoistway 1 or the wall surface of the hoistway 1 may be reached, the operation mode of the group management elevator shifts from normal operation to control operation. Then, when the shaking of the building is stopped, the operation mode of the group control elevator is returned from the control operation to the normal operation.

While the control operation is being performed, the elevator whose long object shake amount reaches the upper limit level is stopped. In this case, even if the shaking of the building is stopped and the normal operation is restored, the elevator cannot be immediately operated because maintenance work such as inspection and repair of parts is required by the maintenance personnel. For this reason, if the amount of vibration of a long object reaches the upper limit level in all elevators that make up the group-controlled elevator during control operation, restart the service immediately even if the building shake has converged. It is impossible to do so and the service must be stopped for a long time.

Therefore, in the group management elevator system according to the present embodiment, when the operation mode of the group management elevator shifts from normal operation to control operation, the distributed standby zone is switched from the normal operation distributed standby zone to the control operation distributed standby zone, The car 2 waiting in the normal operation distributed standby zone is moved to the control operation distributed standby zone. Of the distributed standby zones during control operation, a new hall call is not assigned to the elevator where the car 2 has moved to the priority standby zone, and priority is given to the elevator car 2 until the building shake is resolved. Wait in the standby zone. As a result, the vibration of the long object of the car 2 waiting in the priority waiting zone can be suppressed from being amplified, and the vibration amount of the long object can be suppressed from reaching the upper limit level. As a result, after the building shake has converged and returned to normal operation, at least the elevator in which the car 2 is waiting in the priority standby zone can be operated immediately, and the elevator service stops for a long time. Can be effectively suppressed.

As shown in FIG. 2, the group management control device 20 of the present embodiment includes an operating state monitoring unit 21, a hall call assignment unit 22, a long object shake estimation unit 23, and a distributed standby control unit 24.

The operating state monitoring unit 21 determines whether the elevator single control device 10 is operating the elevator (the current position and traveling direction of the car 2, whether it is moving or stopped, and whether or not there is a hall call or car call that has not completed a response). Etc.) is collected, and the operating states of a plurality of elevators constituting the group-controlled elevator are comprehensively monitored. Then, the operation state monitoring unit 21 passes the information required by these units to the hall call assigning unit 22, the long object shake estimating unit 23, and the distributed standby control unit 24.

The hall call assigning unit 22 determines the number of elevators based on the hall call signal sent from the hall operation panel 15 in response to the operation of the passengers in the hall 3 and the operating state of each elevator sent from the operating state monitoring unit 21. The elevator most suitable for the response of the hall call is determined, and the hall call is assigned to this elevator. This process is called group management control. The hall call assignment unit 22 sends a hall call response command to the elevator single controller 10 to which the hall call is assigned by the group management control. Receiving the hall call response command, the single control device 10 responds to the hall call by moving the car 2 to the floor where the hall call was made (the floor where the hall operation panel 15 was operated).

Here, in the present embodiment, as described above, when the operation mode of the group management elevator shifts from the normal operation to the control operation and one of the elevator cars 2 moves to the priority standby zone, thereafter, This elevator is excluded from the candidates of elevators to which hall calls are assigned as a group outside, and group management control is performed on the remaining elevators excluding this elevator. The elevator in which the car 2 stands by in the priority standby zone is returned to the group when, for example, the building sway converges and the operation mode of the group management elevator returns from the control operation to the normal operation.

When the building shake detector 11 detects the building shake, the long object shake estimation unit 23 determines the size and duration of the building shake, and the elevator car 2 of each elevator specified by the information from the operation state monitoring unit 21. Based on information such as the current position and the traveling direction of the vehicle, the shake amount of each long object of each elevator that constitutes the group control elevator is estimated by a real-time simulation using the shake amount data table 31. Then, when it is predicted that the shake amount of the long object of at least one elevator may reach the upper limit level, the long object shake estimation unit 23 outputs the long object shake signal. The case where it is predicted that the shake amount of the long object of at least one elevator may reach the upper limit level, for example, at least one of the plurality of elevators forming the group management elevator is currently registered. When the car 2 is moved in response to the called call, it is predicted that the shake amount of the long object reaches the upper limit level at the current magnitude of the building shake detected by the building shake detector 11. This is the case when the car 2 passes the floor. The real-time simulation of the shake amount of a long object can be realized by using the technique described in Patent Document 1, for example.

In the group management elevator system according to the present embodiment, when the long object shake estimation unit 23 outputs the long object shake signal, the operation mode of the group management elevator shifts from the normal operation to the control operation. When the building shake converges (that is, the building shake detector 11 does not detect the building shake or the detected building shake falls below a reference value), the operation mode of the group management elevator changes from control operation to normal operation. Return to operation.

In addition, when there is an elevator in which the shake amount of the long object estimated by the above-described real-time simulation reaches the upper limit level, that is, the shake amount of the long object in any elevator is the upper limit. When it is determined that the level has been reached, an operation stop signal for the elevator is output. The operation stop signal output from the long object shake estimation unit 23 is transmitted to the single elevator control device 10 of the target elevator via the distributed standby control unit 24, for example, and the elevator stops operation. In this case, the operation mode of the group-controlled elevator is restored from normal operation to normal operation because the elevator that has stopped operation needs to perform inspection and repair work such as repairs by maintenance personnel after the building shake has converged. Can not be operated immediately.

During the normal operation, the distributed standby control unit 24 causes the elevator cars 2 for which the call response is completed to stand by in the normal operation distributed standby zone. That is, when the response of the call is completed in a certain elevator, the distributed standby control unit 24 determines, based on the information from the operating state monitoring unit 21 and the building data 32, that the plurality of zones constituting the normal operation distributed standby zone are to be operated. It is determined whether there is a zone in which the car 2 is not waiting. Then, if there is a zone in which the car 2 is not waiting, by sending a movement command to the zone to the elevator single control device 10 for which the call response has been completed, the elevator for which the call response has been completed The car 2 is moved to the zone and is made to wait there until a new hall call is assigned.

In addition, when the long object shake estimation unit 23 outputs the long object shake signal and the operation mode of the group management elevator shifts from the normal operation to the control operation, the distributed standby control unit 24 disperses the dispersion standby zone during the normal operation. Switch from the standby zone to the distributed standby zone during control operation. Then, the distributed standby control unit 24 determines, based on the information from the operation state monitoring unit 21 and the building data 32, whether or not there is an elevator in which the car 2 stands by in the normal operation distributed standby zone, and the normal operation is performed. If there is an elevator in which the car 2 stands by in the time-dispersion standby zone, a command to move to the control-time dispersion-standby zone is sent to the elevator single controller 10 to cause the elevator car 2 to move. Move to distributed standby zone during control operation.

At this time, if the number of elevators in which the car 2 is waiting in the normal operation distributed standby zone is one, the distributed standby control unit 24 sets the elevator car 2 to the control operation distributed standby zone. Move to the priority standby zone. Further, if there are a plurality of elevators in which the car 2 is waiting in the normal operation distributed standby zone, the distributed standby control unit 24 causes the car 2 waiting in the zone closest to the priority standby zone to wait for the car 2 in the priority standby zone. Then, the other car 2 is moved to the control operation distributed standby zone other than the priority standby zone.

In addition, when the distributed standby zone is switched from the distributed standby zone during normal operation to the distributed standby zone during control operation, the distributed standby control unit 24 first determines that there is no elevator waiting for the car 2 in the distributed standby zone. The elevator car 2 for which the call response has been completed is moved to the priority standby zone of the control operation distributed standby zones. Then, for the remaining elevators, after the call response is completed, the car 2 of the elevators is moved to the control standby distributed standby zone other than the priority standby zone.

In addition, until the car 2 moving to the priority waiting zone reaches the priority waiting zone, the shake amount of the long object connected to the car 2 by the long object shake estimation unit 23 reaches the upper limit level. In some cases, it may be determined that the car 2 has been reached, and an operation stop signal may be output to stop the car 2. In this case, the distributed standby control unit 24 moves the elevator cars 2 of other elevators to the priority standby zone. That is, at the time of control operation, control is performed so that at least one elevator car 2 always waits in the priority standby zone.

The car 2 that has moved to a zone other than the priority standby zone among the distributed standby zones during control operation stands by in that zone until a new hall call is assigned. On the other hand, the car 2 that has moved to the priority waiting zone is excluded from the target of the hall call assignment, and remains in the priority waiting zone until the building shake is converged and the operation mode of the group control elevator returns from the control operation to the normal operation. stand by. At this time, the distributed standby control unit 24 controls the display of the hall indicator 14 corresponding to the elevator in which the car 2 stands by in the priority waiting zone, and the hall indicator 14 indicates, for example, "standby in the priority waiting zone". It is desirable to display information. Further, the distributed standby control unit 24 notifies the elevator monitoring room of identification information such as the elevator machine number of the car 2 waiting in the priority standby zone, and the elevator for monitoring the operating state of each elevator in the elevator monitoring room. Of the operation indicator lights of the monitoring panel, the operation indicator lights corresponding to the elevators in which the car 2 stands by in the priority standby zone may be turned off.

Next, an example of the operation control method of the group management elevator executed by the group management control device 20 of the present embodiment will be described with reference to FIG. FIG. 4 is a flowchart showing an example of a processing procedure of the group management control device 20 during the control operation. In step S101 of FIG. 4, when the building shake sensor 11 detects building shake and a long object shake estimation unit 23 outputs a long object shake signal, the operation mode of the group management elevator changes from normal operation to control operation. Move to. In this case, the group supervisory control device 20 performs the processing of steps S102 to S109 of FIG. 4 so that at least one elevator can immediately start operation when the building shake has converged and returned to normal operation. ..

When the operation mode of the group management elevator is changed from normal operation to control operation, the group management control device 20 first switches the distributed standby zone from the normal operation distributed standby zone to the control operation distributed standby zone (step S102). Then, the group management control device 20 confirms whether or not there is an elevator in which the car 2 is waiting in the normal operation distributed standby zone (step S103), and the car 2 is waiting in the normal operation distributed standby zone. If there is an elevator (step S103: Yes), the car 2 of the elevator is moved to the control operation distributed standby zone (step S104).

At this time, as described above, if the number of elevators in which the car 2 stands by in the normal operation distributed standby zone is one, the group management control device 20 distributes the car 2 of the elevator during control operation. Move to the priority standby zone among the standby zones. Also, if there are a plurality of elevators in which the car 2 is waiting in the normal operation distributed standby zone, the group management control device 20 causes the car 2 waiting in the zone closest to the priority standby zone to be the priority standby zone. Then, the other car 2 is moved to the control operation distributed standby zone other than the priority standby zone.

On the other hand, when there is no elevator in which the car 2 stands by in the normal operation distributed standby zone (step S103: No), the group management control device 20 gives priority to the car 2 of the elevator whose call response is completed first. It is moved to the standby zone (step S105). For the remaining elevators, after the call response is completed, the elevator car 2 is moved to the control standby distributed standby zone other than the priority standby zone.

Here, the group management control device 20 determines that the shake amount of the long object connected to the car 2 reaches the upper limit level until the car 2 moving to the priority standby zone arrives at the priority standby zone. It is determined whether it has reached (step S106). When it is determined that the shake amount of the long object reaches the upper limit level (step S106: Yes), the group management control device 20 stops the elevator car 2 and returns to step S103 to repeat the process. As a result, the car 2 of another elevator is moved to the priority waiting zone.

On the other hand, when the car 2 arrives at the priority standby zone without the amount of swinging of the long object reaching the upper limit level (step S106: No), the group management control device 20 causes the car 2 to move to the priority standby zone. Is carried out outside the group (step S107), and while the shaking of the building continues (step S108: No), the car 2 moved to the priority waiting zone is made to stand by in the priority waiting zone. As described above, the priority standby zone is a zone in which the long object connected to the car 2 is less likely to resonate with the shaking of the building among the distributed standby zones during the control operation. Therefore, by making one elevator car 2 stand by in the priority waiting zone during the control operation, the long object of the elevator is prevented from swinging.

After that, when the building shake is converged (step S108: Yes), the operation mode of the group management elevator is returned from the control operation to the normal operation. In accordance with this, the group management control device 20 restores the distributed standby zone from the distributed standby zone during control operation to the distributed standby zone during normal operation (step S109), and thereafter, the distributed standby zone using the distributed standby zone during normal operation. I do.

As described above in detail with reference to specific examples, in the group management elevator system according to the present embodiment, the building shake is detected, and the shake amount of the long object of at least one elevator reaches the upper limit level. When it is predicted that there is a risk, the group management control device 20 changes the distributed standby zone from the normal operation distributed standby zone (first distributed standby zone) to the control operation distributed standby zone (second distributed standby zone). Then, the car 2 waiting in the normal operation distributed standby zone is moved to the control operation distributed standby zone. Then, for the elevator in which the car 2 has moved to the priority standby zone in which the long objects are most unlikely to resonate with building shaking in the distributed standby zone during control operation, a new hall call is not assigned to the elevator car 2 is made to wait in the priority waiting zone until the building shakes converge. Therefore, according to the present embodiment, at least for the elevators in which the car 2 stands by in the priority waiting zone, it is possible to effectively suppress the shake amount of the long object from reaching the upper limit level, and the building shake converges and becomes normal. It can be operated immediately after returning to operation. As a result, it is possible to effectively suppress the inconvenience that the elevator service is stopped for a long time.

<Second Embodiment>
Next, a second embodiment will be described. The present embodiment is different from the above-described first embodiment in that the operation mode of the group control elevator shifts from normal operation to control operation. That is, in the above-described first embodiment, when the building shake sensor 11 detects a building shake, and it is predicted that the shake amount of at least one elevator long object may reach the upper limit level (long object). When the object shake estimation unit 23 outputs a long object shake signal), the operation mode of the group control elevator shifts from the normal operation to the control operation. On the other hand, in the present embodiment, when the earthquake early warning signal is received, the operation mode of the group management elevator shifts from the normal operation to the control operation.

FIG. 5 is a schematic configuration diagram of the group management elevator system according to the present embodiment. The difference from the configuration of the first embodiment shown in FIG. 2 is that a receiving unit 25 is added to the group management control device 20. The receiving unit 25 receives the earthquake early warning signal when it is issued, and notifies the distributed standby control unit 24 that the emergency earthquake early warning signal has been received.

In the group management control device 20 of the present embodiment, when the receiving unit 25 receives the earthquake early warning signal, the distributed standby control unit 24 moves the distributed standby zone from the normal operation distributed standby zone (first distributed standby zone). By switching to the distributed standby zone during the control operation (second distributed standby zone), the same processing as in the above-described first embodiment is performed.

That is, the group management control device 20 according to the present embodiment receives the long object shake signal from the long object shake estimation unit 23 instead of determining whether or not the long object shake signal is output in step S101 shown in the flowchart of FIG. It is determined whether the unit 25 has received the earthquake early warning signal. Then, when the receiving unit 25 receives the earthquake early warning signal, the group management control device 20 performs the processing of steps S102 to S109 of FIG. 4 and when the building shake converges and returns to normal operation, At least one elevator should be ready for operation.

As described above, in the present embodiment, the group management control device 20 moves the distributed standby zone from the normal operation distributed standby zone (first distributed standby zone) to the control operation distributed standby when the earthquake early warning signal is received. By switching to the zone (second distributed standby zone), the car 2 waiting in the normal operation distributed standby zone is moved to the control operation distributed standby zone. Then, for the elevator in which the car 2 has moved to the priority standby zone in which the long objects are most unlikely to resonate with building shaking in the distributed standby zone during control operation, a new hall call is not assigned to the elevator car 2 is made to wait in the priority waiting zone until the building shakes converge. Therefore, also in the present embodiment, similarly to the above-described first embodiment, it is possible to effectively prevent the shake amount of the long object from reaching the upper limit level for at least the elevator in which the car 2 stands by in the priority standby zone. Thus, the building can be put into operation immediately after the shaking of the building converges and the normal operation is restored. As a result, it is possible to effectively suppress the inconvenience that the elevator service is stopped for a long time.

According to at least one embodiment described above, at least one elevator can be operated immediately after the building shake is converged, and the inconvenience of a long service outage can be effectively suppressed.

Although the specific embodiment of the present invention has been described above, this embodiment is presented as an example and is not intended to limit the scope of the invention. This embodiment can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. This embodiment and its modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and the scope equivalent thereto.

The operation control method of the group management elevator of the embodiment is an operation control method of a group management elevator having a plurality of group-managed elevators, and a plurality of elevator cars that have completed the response to the call are placed in a distributed standby state. As a distributed standby zone consisting of zones, a first distributed standby zone and a second distributed standby zone are defined, building shaking is detected, and connected to at least one elevator car among the plurality of elevators.

A priority waiting zone in which a car waiting in the distributed standby zone is moved to the second distributed standby zone, and the long object is the zone most unlikely to resonate with building shaking in the second distributed standby zone. No new hall call is assigned to the elevator that the car has moved to, the elevator car is made to wait in the priority waiting zone until the building shake is converged , and the distributed waiting zone is moved from the first distributed waiting zone to the When there is no elevator waiting for a car in the first distributed standby zone when switching to the second distributed standby zone, the elevator car that has completed the call response first becomes the priority standby zone. The elevator car that has been moved to the priority waiting zone is not assigned a new call, the elevator car is made to wait in the priority waiting zone until the building shake is converged, and the car is moving to the priority waiting zone. When it is determined that the deflection amount of the long object of the elevator reaches the upper limit level, the car of the elevator is stopped and the cars of other elevators are moved to the priority waiting zone .
