  Hereinafter, a specific embodiment of an operation control method and a group management control device of a group management elevator 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 constituting the group management elevator. As shown in FIG. 1, each elevator constituting the group control elevator moves up and down a car 2 in a hoistway 1 provided in a building having a plurality of floors, so that the elevator 2 in a car 2 from a landing 3 on a certain floor. Is a transporting means for transporting a passenger who has boarded to a landing 3 on another floor. The car 2 is connected to a counterweight 5 via a main rope 4. When the main rope 4 is fed by the drive of the hoist 6, the car 2 moves up and down in the hoistway 1 while balancing with the counterweight 5.

  A lower part of the hoistway 1 is provided with a compensive 7 and a buffer (not shown). The compensive 7 is wound around a compensating rope 8 having both ends connected to the lower part of the car 2 and connected to the lower part of the weight 5. The compensating rope 8 has a role of offsetting 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 above-described hoisting machine 6 is provided in a machine room 9 above the hoistway 1. In the machine room 9, in addition to the hoisting machine 6, a single control device 10 for each elevator constituting the group control elevator, a group control device 20, and a building shake sensor 11 such as an acceleration sensor for detecting the building shake. Are provided. The hoisting machine 6, the unit 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 single control device 10 includes a microcomputer having a CPU, a ROM, a RAM, and the like, registers a car call, controls the movement of the car 2 (drive control of the hoisting machine 6) according to the car call and the hall call, It controls the operation of the elevator alone, such as opening and closing control of the door of the car 2. The single controller 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 having a CPU, a ROM, a RAM, and the like, and assigns hall calls to the elevators (group management control) while monitoring the operating states of the plurality of elevators. The group management control device 20 is connected to the single control device 10 of each elevator constituting the group management elevator. Further, the 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. As shown in FIG. 2, a landing door 13 that opens and closes in conjunction with a door of the car 2 in the landing 3 on each floor of the building where the group management elevator is installed, as shown in FIG. And a hall display 14 for displaying various information. The hall 3 on each floor is provided with a hall operation panel 15 operated by a passenger to make a hall call. The hall operating panel 15 and the hall display 14 are connected to the group management control device 20. In the example shown in FIG. 2, the number of elevators constituting the group control elevator is three, but the number of elevators is arbitrary.

  The group management elevator according to the present embodiment has a distributed standby function. The distributed standby function is to distribute the elevator car 2 that has completed the call response to a distributed standby zone composed of a plurality of zones that are determined to be distributed from the lower floor to the upper floor of the building. This is the function to make the system wait. When the car 2 is not waiting in at least one of the plurality of zones constituting the decentralized standby zone, the car 2 of the elevator that has completed the answering of the call is vacant instead of waiting on the spot ( Move to the zone where no other car 2 is waiting) and wait there until a new hall call is assigned. In the distributed standby function, when a hall call is made on a certain floor, the hall call is assigned to the car 2 waiting in a zone near the floor, so that the waiting time at the hall can be reduced.

  Here, in the group management elevator according to the present embodiment, in particular, a normal operation dispersion standby zone (first dispersion standby zone) and a control operation Two types of distributed standby zones, a time distributed standby zone (second distributed standby zone), are defined. Then, as described later, when the operation mode of the group control elevator shifts from the normal operation to the control operation, the dispersion standby zone is switched from the normal operation dispersion standby zone to the control operation dispersion standby zone.

  When the building shakes due to the influence of a long-period earthquake, strong wind, or the like, a long object (the main rope 4, the compensating rope 8, the tail cord 12, and the like) connected to the car 2 may resonate with the building shake. The degree of resonance of the long object differs depending on the floor where the car 2 is located. The swing amount of the long object due to the building shake can be estimated from the magnitude of the building shake, the duration during which the building shake of that size continues, and the floor where 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 swing amount of the long object when the car 2 is on that floor is determined for each combination of the magnitude of the building swing and the duration time. And the group management control device 20 holds the estimation result as a shake amount data table 31. This shake amount data table 31 is similar to the data table used in the real-time simulation disclosed in Patent Document 1.

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

  Furthermore, in this embodiment, the above-mentioned normal operation dispersion standby zone and the control operation dispersion standby zone are determined in advance. Then, information indicating the resonance level of each floor of the building, and information indicating the number of floors in the building where the plurality of zones constituting the normal operation dispersion standby zone and the plurality of zones constituting the control operation dispersion standby zone are located, respectively. As the building data 32 in the group management control device 20.

  FIG. 3 shows an example of the building data 32 held by the group management control device 20. The building data 32 shown in FIG. 3 is an example of a case where the first to twentieth floors of a building are to be serviced by the group management elevator and the distributed standby zone is composed of three zones. The resonance levels of the respective floors up to the floor are shown in three stages from level 1 to level 3, and floors set in three zones (zones A, B, C) constituting a normal operation dispersion standby zone; The floors set in the three zones (zones A, B, and C) constituting the control operation dispersion standby zone are shown. As can be seen from the example of FIG. 3, the three zones constituting the normal operation dispersion standby zone are uniformly distributed from the lower floor to the upper floor of the building. On the other hand, the three zones constituting the control operation dispersion standby zone are set from the viewpoint that a long object connected to the car 2 does not easily resonate with the building shake. Among the three zones constituting the control operation dispersion standby zone, a zone (a zone B in the example of FIG. 3) in which a long object is least likely to resonate with a building shake is referred to as a “priority standby zone”.

  In the group management elevator system according to the present embodiment, the building shake is detected by the building shake sensor 11, and the shake amount of at least one elevator long object is set to the upper limit level (for example, based on the shake amount data table 31). , The level of contact with the equipment in the hoistway 1 and the wall surface of the hoistway 1, etc.), the operation mode of the group control elevator shifts from normal operation to control operation. Then, when the shaking of the building stops, the operation mode of the group control elevator returns from the control operation to the normal operation.

  During the control operation, the elevator in which the swing amount of the long object reaches the upper limit level stops the operation. In this case, even if the shaking of the building converges and returns to normal operation, the elevator cannot be operated immediately because maintenance work such as inspection and repair of parts is required. For this reason, if the swing amount of a long object reaches the upper limit level in all elevators that make up the group control elevator during the control operation, the service should be restarted immediately even if the building shake has converged. 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 the normal operation to the control operation, the dispersion standby zone is switched from the normal operation dispersion standby zone to the control operation dispersion standby zone, The car 2 waiting in the normal operation dispersion standby zone is moved to the control operation dispersion standby zone. Then, a new hall call is not assigned to the elevator in which the car 2 has moved to the priority standby zone, particularly the car 2 of the elevator, until the swing of the building converges. Have the user wait in the standby zone. Thus, the swing of the long object in the car 2 waiting in the priority standby zone is suppressed from being amplified, and the swing amount of the long object can be suppressed from reaching the upper limit level. As a result, the elevator in which the car 2 is waiting at least in the priority standby zone can be operated immediately after the building shake has converged and returned to normal operation, and the elevator service is stopped 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 operation state monitoring unit 21, a hall call assignment unit 22, a long object swing estimation unit 23, and a distributed standby control unit 24.

  The operating state monitoring unit 21 receives the elevator operating state (the current position and traveling direction of the car 2, whether the car 2 is moving or stopped, and whether there is a hall call or a car call for which the response has not been completed) from the individual controller 10 of each elevator. And the like, and collectively monitor the operating states of a plurality of elevators constituting the group control elevator. Then, the operating state monitoring unit 21 passes information required by these units to the hall call assigning unit 22, the long object swing estimating unit 23, and the distributed standby control unit 24.

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

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

  When the building shake sensor 11 detects the building shake, the long object shake estimation unit 23 determines the magnitude and duration of the building shake and the elevator car 2 specified by the information from the operation state monitoring unit 21. Based on the information on the current position and traveling direction of the elevator, the swing amount of the long object of each elevator constituting the group control elevator is estimated by real-time simulation using the shake amount data table 31. Then, when it is predicted that the swing amount of at least one elevator long object may reach the upper limit level, the long object shake estimation unit 23 outputs a long object shake signal. When it is predicted that the swing 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 constituting the group management elevator is currently registered. When the car 2 is moved in response to the call being made, it is predicted that the swing amount of the long object reaches the upper limit level according to the current magnitude of the building shake detected by the building shake sensor 11. This is the case where the car 2 will pass through the floor. In addition, the real-time simulation of the runout amount of a long object can be realized using, for example, the technology described in Patent Document 1.

  In the group management elevator system according to the present embodiment, when the long object shake estimation signal is output from the long object shake estimation unit 23, the operation mode of the group management elevator shifts from normal operation to control operation. Then, when the building shake converges (that is, when the building shake sensor 11 stops detecting the building shake or when the magnitude of the detected building shake falls below the reference value), the operation mode of the group control elevator changes from the control operation to the normal operation mode. Return to operation.

  Further, the long object shake estimating unit 23 determines that there is an elevator in which the shake amount of the long object estimated by the above-described real-time simulation has reached the upper limit level, that is, the shake amount of the long object in any one of the elevators has the upper limit. If 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 estimating unit 23 is transmitted to, for example, the single control device 10 of the target elevator via the distributed standby control unit 24, and the elevator stops operating. In this case, the elevator that has stopped operating needs to perform maintenance work such as inspection and parts repair by maintenance personnel after the building shake has converged, so the operation mode of the group management elevator returns from control operation to normal operation. Cannot be activated immediately.

  During normal operation, the dispersion standby control unit 24 causes the elevator car 2 that has completed the call response to be distributed and standby in the normal operation dispersion standby zone. That is, when a call response is completed in a certain elevator, the distributed standby control unit 24 determines a plurality of zones constituting the normal operation distributed standby zone based on the information from the operation state monitoring unit 21 and the building data 32. It is determined whether there is a zone in which the car 2 is not waiting. If there is a zone in which the car 2 is not waiting, the movement command to the single control device 10 of the elevator that has completed the call response is sent to the elevator 2 that has completed the call response. Car 2 is moved into that zone, where it waits until a new hall call is assigned.

  Further, when the long object shake signal is output from the long object shake estimation unit 23 and the operation mode of the group control elevator shifts from the normal operation to the control operation, the dispersion standby control unit 24 changes the dispersion standby zone to the normal operation dispersion. Switch from the standby zone to the control operation distributed standby zone. Then, based on the information from the operation state monitoring unit 21 and the building data 32, the distributed standby control unit 24 determines the presence or absence of an elevator in which the car 2 is waiting in the normal operation distributed standby zone. If there is an elevator in which the car 2 is waiting in the time-dispersion standby zone, the elevator 2 is sent a command to move to the control-operation-time dispersion standby zone to the single control device 10 of the elevator, so that the elevator 2 Move to the dispersion standby zone during control operation.

  At this time, if there is only one elevator in which the car 2 is waiting in the normal operation dispersion standby zone, the distribution standby control unit 24 causes the elevator car 2 to move out of the control operation dispersion standby zone. Move to priority standby zone. If there are a plurality of elevators in which the car 2 is waiting in the normal operation dispersion standby zone, the distributed standby control unit 24 sets the car 2 waiting in the zone closest to the priority standby zone to the priority standby zone. And the other car 2 is moved to the control operation dispersion standby zone other than the priority standby zone.

  In addition, when the dispersion standby control unit 24 switches the dispersion standby zone from the normal operation dispersion standby zone to the traffic control operation dispersion standby zone, if there is no elevator in which the car 2 is waiting in the dispersion standby zone, The elevator car 2 whose call response has been completed is moved to the priority standby zone of the control operation distributed standby zone. Then, for the remaining elevators, after the call response is completed, the car 2 of the elevator is moved to the control operation dispersed standby zone other than the priority standby zone.

  By the time the car 2 moving to the priority waiting zone arrives at the priority waiting zone, the swing amount of the long object connected to the car 2 by the long object swing estimating unit 23 reaches the upper limit level. In some cases, it is determined that the vehicle speed has reached the predetermined time, and an operation stop signal is output to stop the car 2. In this case, the distributed standby control unit 24 moves the car 2 of another elevator to the priority standby zone. That is, at the time of the control operation, control is performed such 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 in the control operation dispersed standby zone waits in that zone until a new hall call is assigned. On the other hand, the car 2 that has moved to the priority standby zone is excluded from the target of the hall call assignment, and remains in the priority standby zone until the swing of the building converges 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 display 14 corresponding to the elevator in which the car 2 stands by in the priority standby zone, and the hall display 14 displays, for example, “waiting in the priority standby zone”. It is desirable to display information. In addition, the distributed standby control unit 24 notifies the elevator monitoring room of identification information such as the elevator number of the elevator in which the car 2 stands by in the priority standby zone, and the elevator monitoring room monitors the operating state of each elevator. Among the operation indicators on the monitoring panel, the operation indicators corresponding to the elevators in which the car 2 stands by in the priority standby zone may be turned off.

  Next, an example of an 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 illustrating 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 is detected by the building shake sensor 11 and the long object shake estimating unit 23 outputs a long object shake signal, the operation mode of the group control elevator changes from the normal operation to the control operation. Move to In this case, the group management control device 20 performs the processing of steps S102 to S109 in FIG. 4 so that at least one elevator can be operated immediately when the building shake has converged and returned to normal operation. .

  When the operation mode of the group management elevator shifts from the normal operation to the control operation, the group management control device 20 first switches the dispersion standby zone from the normal operation dispersion standby zone to the control operation dispersion standby zone (step S102). Then, the group management control device 20 checks whether there is an elevator in which the car 2 is waiting in the normal operation dispersion standby zone (step S103), and the car 2 is waiting in the normal operation dispersion standby zone. If there is an elevator (Step S103: Yes), the car 2 of the elevator is moved to the control operation dispersion standby zone (Step S104).

  At this time, as described above, if there is one elevator in which the car 2 is waiting in the normal operation dispersion standby zone, the group management control device 20 transmits the elevator car 2 in the control operation dispersion state. Move to the priority standby zone of the standby zone. 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 sets the car 2 waiting in the zone closest to the priority standby zone to the priority standby zone. And the other car 2 is moved to the control operation dispersion standby zone other than the priority standby zone.

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

  Here, the group management control device 20 sets the swing amount of the long object connected to the car 2 to the upper limit level before the car 2 moving to the priority standby zone arrives at the priority standby zone. It is determined whether or not it has reached (step S106). When it is determined that the swing amount of the long object has reached the upper limit level (Step S106: Yes), the group management control device 20 stops the elevator car 2, returns to Step S103, and repeats the processing. Thereby, the car 2 of another elevator is moved to the priority standby zone.

  On the other hand, when the car 2 arrives at the priority standby zone without the swing amount of the long object reaching the upper limit level (step S106: No), the group management control device 20 determines that the elevator in which the car 2 has moved to the priority standby zone. Is performed outside the group (step S107), and while the building shake continues (step S108: No), the car 2 that has moved to the priority standby zone is made to wait in the priority standby 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 building shake among the standby standby zones during the traffic control operation. Therefore, by making the car 2 of one elevator stand by in the priority standby zone during the control operation, the swing of the long object of the elevator is suppressed.

  After that, when the building shake converges (Step S108: Yes), the operation mode of the group control elevator returns from the control operation to the normal operation. In accordance with this, the group management control device 20 returns the dispersion standby zone from the control operation dispersion standby zone to the normal operation dispersion standby zone (step S109), and thereafter, the dispersion standby using the normal operation dispersion standby zone. I do.

  As described above in detail with reference to a specific example, in the group management elevator system according to the present embodiment, a building shake is detected, and the swing amount of at least one long object 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). And the car 2 waiting in the normal operation dispersion standby zone is moved to the control operation dispersion standby zone. Then, a new hall call is not assigned to the elevator in which the car 2 has moved to the priority standby zone in which the long object is least likely to resonate with the shaking of the building in the distributed standby zone during the traffic control operation, without assigning a new hall call. 2 is made to wait in the priority waiting zone until the building shake is converged. Therefore, according to the present embodiment, at least for the elevator in which the car 2 waits in the priority standby zone, the swing amount of the long object is effectively suppressed from reaching the upper limit level, and the building shake is converged and the normal state. It can be operated immediately after returning to operation. Thereby, the inconvenience of the elevator service being stopped for a long time can be effectively suppressed.

<Second embodiment>
Next, a second embodiment will be described. The present embodiment is different from the above-described first embodiment in the opportunity that the operation mode of the group control elevator shifts from the normal operation to the control operation. That is, in the first embodiment described above, the building shake is detected by the building shake sensor 11, and it is predicted that there is a possibility that the swing amount of the long object of at least one elevator reaches the upper limit level (long). The operation mode of the group control elevator shifts from the normal operation to the control operation when the object shake estimating unit 23 outputs the long object shake signal). On the other hand, in the present embodiment, when an emergency earthquake early warning signal is received, the operation mode of the group control elevator shifts from normal operation to 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 reception unit 25 is added to the group management control device 20. When the emergency earthquake early warning signal is issued, the receiving unit 25 receives the signal and notifies the distributed standby control unit 24 of the reception of the emergency earthquake early warning signal.

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

  That is, in step S101 shown in the flowchart of FIG. 4, the group management control device 20 according to the present embodiment receives a long object shake signal instead of determining whether the long object shake signal is output from the long object shake estimation unit 23. It is determined whether the unit 25 has received the emergency earthquake early warning signal. Then, when the receiving unit 25 receives the emergency earthquake early warning signal, the group management control device 20 performs the processing of steps S102 to S109 in FIG. 4 and returns to normal operation when the building shake has converged and returned to normal operation. At least one elevator shall be ready for operation.

  As described above, in the present embodiment, the group management control device 20 changes the dispersion standby zone from the normal operation dispersion standby zone (the first dispersion standby zone) to the control operation dispersion standby when the emergency earthquake early warning signal is received. Switching to the zone (second dispersion standby zone), the car 2 waiting in the normal operation dispersion standby zone is moved to the control operation dispersion standby zone. Then, a new hall call is not assigned to the elevator in which the car 2 has moved to the priority standby zone in which the long object is least likely to resonate with the shaking of the building in the distributed standby zone during the traffic control operation, without assigning a new hall call. 2 is made to wait in the priority waiting zone until the building shake is converged. Therefore, also in the present embodiment, as in the first embodiment described above, at least for the elevator in which the car 2 waits in the priority standby zone, the swing amount of the long object is effectively suppressed from reaching the upper limit level. As a result, the building can be operated immediately after the shaking has converged and the operation has returned to normal operation. Thereby, the inconvenience of the elevator service being stopped for a long time can be effectively suppressed.

  According to at least one embodiment described above, at least one elevator can be operated immediately after the building sway has converged, so that inconvenience such as a long service stop can be effectively suppressed.

  The specific embodiment of the present invention has been described above, but this embodiment is presented as an example and is not intended to limit the scope of the invention.
