Abstract

The present invention relates to an operation control method and a group management control device for a group management elevator. After the building sway converges, at least 1 elevator can be immediately operated, and the defect of long-time service stop is effectively inhibited. A first distributed standby area and a second distributed standby area are predetermined as distributed standby areas for dispersedly waiting cars of an elevator for which a call response is completed. When the building sway is detected and it is predicted that the vibration amount of the long object of at least 1 elevator may reach the upper limit level, the distributed standby area is switched from the first distributed standby area to the second distributed standby area, and the car waiting in the first distributed standby area is moved to the second distributed standby area. The car of the elevator waits in the priority waiting area until the sway of the building converges without assigning a new landing call to the elevator whose car moves to the priority waiting area, which is an area in the second dispersed waiting area where the long object is most difficult to resonate with the sway of the building.

Description

Operation control method for group management elevator and group management control device

The present application is based on and enjoys priority from Japanese patent application 2018-229989 (application date: 12/07 in 2018). This application incorporates by reference the entirety of this application.

Technical Field

The embodiment of the invention relates to an operation control method and a group management control device of a group management elevator.

Background

When building sway occurs due to the influence of a long-period earthquake, a strong wind, or the like, long objects (such as a main rope, a compensating rope, and a lead wire (hereinafter, referred to as "tail cord") connected to a car) of an elevator installed in the building may resonate with the building sway and largely vibrate. Therefore, the following proposals have been made: the vibration amount of the long article is estimated by real-time simulation based on the magnitude and duration of the building sway and the position of the car, and the control operation is performed in accordance with the estimated vibration amount of the long article.

When the vibration amount of the long article reaches an upper limit level of contact with equipment, a hoistway wall, and the like in the hoistway, the elevator stops operating. In this case, in order to ensure the safety of the elevator, it is necessary to perform recovery work such as inspection and component repair by a maintenance worker after the sway of the building has converged. Therefore, when the vibration amount of the long object reaches the upper limit level in all the elevators constituting the group management elevator, the service cannot be immediately restarted even if the building sway converges, and the service has to be stopped for a long time. Under such circumstances, it is required to operate at least 1 elevator immediately after the sway of the building converges.

Disclosure of Invention

The problem to be solved by the present invention is to provide an operation control method and a group management control device for group management elevators, which can immediately operate at least 1 elevator after the sway of a building converges, and can effectively suppress a long-time service stop.

An operation control method of a group management elevator of an embodiment is an operation control method of a group management elevator having a plurality of elevators to be group managed, wherein a first dispersed standby zone and a second dispersed standby zone are predetermined as dispersed standby zones configured by a plurality of zones in which cars of elevators having finished responding to a call are dispersed and standby, when a building sway is detected and it is predicted that an amount of vibration of a long article connected to the cars of at least 1 of the plurality of elevators is likely to reach an upper limit level, the dispersed standby zones are switched from the first dispersed standby zone to the second dispersed standby zone, the cars standing by in the first dispersed standby zone are moved to the second dispersed standby zone, a new landing call is not assigned to the elevator whose car is moved to a priority standby zone, and the cars of the elevators are made to stand by in the priority standby zone until the building sway converges, the priority standby area is an area in which the long object is most unlikely to resonate with building sway in the second dispersed standby area.

According to the operation control method of the group management elevator with the above configuration, at least 1 elevator can be immediately operated after the sway of the building converges, and a trouble such as a service stop for a long time can be suppressed.

Detailed Description

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 a group management elevator. As shown in fig. 1, each elevator constituting the group management elevator is a transport mechanism as follows: by raising and lowering the car 2 in the hoistway 1 provided in a building having multiple floors, passengers boarding from a landing 3 on a certain floor into the car 2 are transported to a landing 3 on another floor. The car 2 is coupled to a counterweight 5 via a main rope 4. Then, the main ropes 4 are driven by the hoist 6 to perform a conveying operation, whereby the car 2 is lifted and lowered in the lifting path 1 while being balanced with the counterweight 5.

A compensating sheave 7, a not-shown buffer, and the like are provided below the elevator shaft 1. A compensating rope 8 having both ends connected to the lower portion of the car 2 and the lower portion of the counterweight 5 is wound around the compensating sheave 7. The compensating ropes 8 have a function of canceling out a change in the weight balance of the main ropes 4 caused as the car 2 moves up and down in the elevator shaft 1.

The hoist 6 is provided in a machine room 9 above the hoistway 1. In addition to the hoisting machine 6, the machine room 9 is provided with a building sway detector 11 such as a single-body control device 10, a group management control device 20, and an acceleration sensor that senses building sway, which constitute each elevator that manages the group. In addition, the hoist 6, the individual control device 10, the group management control device 20, the building sway detector 11, and the like may be disposed in the ascending/descending path 1 without providing the machine room 9.

The cell control device 10 includes a microcomputer including a CPU, a ROM, a RAM, and the like. The individual control device 10 controls the operation of the elevator alone, such as registration of a car call, control of movement of the car 2 (drive control of the hoisting machine 6) according to the car call and a hall call, and control of opening and closing of the door of the car 2. The individual control device 10 is connected to the car 2 by a lead wire 12, and supplies power to the car 2 and exchanges various signals with each other through the lead wire 12.

The group management control device 20 includes a microcomputer including a CPU, a ROM, a RAM, and the like. The group management control device 20 monitors the operating states of a plurality of elevators and assigns hall calls to the elevators (group management control). The group management control device 20 is connected to the individual control devices 10 of the elevators constituting the group management elevator. Further, a building sway detector 11 is 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, in the landing 3 of each floor of the building in which the group management elevator is installed, a landing door 13 that opens and closes in conjunction with the door of the car 2 and a landing display 14 that displays various information are provided in correspondence with each elevator constituting the group management elevator. In addition, a landing 3 on each floor is provided with a landing operating panel 15 that is operated by a passenger to make a landing call. The landing operating panel 15 and the landing display 14 are connected to the group management control device 20. In the example shown in fig. 2, the number of elevators to be managed as a constituent group is 3, but the number of elevators is arbitrary.

The group management elevator of the present embodiment has a distributed standby function. The distributed standby function is a function of: the car 2 of the elevator for which the call response is completed is distributed and placed on standby in a distributed standby zone including a plurality of zones defined so as to be distributed and arranged from the lower floor to the upper floor of the building. When no car 2 is standing by in at least any one of the plurality of zones constituting the distributed standby zone, the car 2 of the elevator for which the response to the call is completed moves to a vacant zone (other car 2 is not standing by) without directly standing by, and stands by until a new hall call is assigned. In the distributed waiting function, when a hall call is present on a floor, the hall call is assigned to the car 2 waiting in the area close to the floor, thereby reducing the waiting time at the hall.

Here, in the group management elevator of the present embodiment, in particular, as a distributed standby zone configured by a plurality of zones in which the cars 2 are distributed and standby, two kinds of distributed standby zones, i.e., a distributed standby zone during normal operation (first distributed standby zone) and a distributed standby zone during controlled operation (second distributed standby zone), are specified. Then, as will be described later, when the operation mode of the group management elevator is shifted from the normal operation to the controlled operation, the distributed standby area is switched from the normal operation distributed standby area to the controlled operation distributed standby area.

When the building sways due to the influence of a long-period earthquake, a strong wind, or the like, the long objects (the main rope 4, the compensating rope 8, the lead wire 12, and the like) connected to the car 2 may resonate with the building sway. The degree of resonance of the long article varies depending on the floor on which the car 2 is located. The amount of vibration of the long object accompanying the building sway can be estimated from the magnitude of the building sway, the duration of time during which the building sway of that magnitude continues, and the floor on which the car 2 is located. Therefore, in the present embodiment, the vibration amount of the long object when the car 2 is on the floor is estimated for each floor of the building where the group management elevator is installed, from each combination of the magnitude and duration of the building sway, and the estimation result is held in the group management control device 20 as the vibration amount data table 31. The vibration amount data table 31 is the same as the data table used in the real-time simulation disclosed in patent document 1.

In the present embodiment, a resonance level indicating the degree of resonance between the elongated object connected to the car 2 and the building sway is set for each floor of the building in which the group management elevator is installed. For example, by using the vibration amount data table 31, when a building of a predetermined size is shaken for a predetermined time, the vibration amount of the long object in each floor is previously checked to what degree, and thus the resonance level of each floor can be set.

In the present embodiment, the above-described normal operation time dispersion standby region and controlled operation time dispersion standby region are determined in advance. Then, information indicating the resonance level of each floor of the building and information indicating which floor of the building each of the plurality of areas constituting the distributed standby area during normal operation and the plurality of areas constituting the distributed standby area during regulated operation are held as 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 distributed standby area is configured by 3 areas, with the object of service by the group management elevator being from 1 floor to 20 floors of the building. In the example of fig. 3, the resonance levels of the layers from 1 layer to 20 layers are represented by 3 stages of level 1 to level 3, and each layer is set in 3 regions (region A, B, C) constituting the dispersion standby region during normal operation and in 3 regions (region A, B, C) constituting the dispersion standby region during controlled operation. As can be seen from the example of fig. 3, 3 zones constituting the distributed standby zones during normal operation are distributed evenly across from the lower floor to the upper floor of the building. On the other hand, the 3 zones constituting the distributed standby zone in the controlled operation are set from the viewpoint that the long object connected to the car 2 is less likely to resonate with the building sway. Of the 3 zones constituting the distributed standby zone during the controlled operation, a zone (zone B in the example of fig. 3) in which the long object is most likely to resonate with the building sway is referred to as a "priority standby zone".

In the group management elevator system of the present embodiment, when the building sway is detected by the building sway detector 11 and it is predicted based on the vibration amount data table 31 that there is a possibility that the vibration amount of the long article of at least 1 elevator reaches the upper limit level (for example, a level of contact with the equipment in the elevator shaft 1, the wall surface of the elevator shaft 1, or the like), the operation mode of the group management elevator is shifted from the normal operation to the controlled operation. Then, when the building sway converges, the operation mode of the group management elevator is restored from the regulated operation to the normal operation.

During the control operation, the elevator in which the vibration amount of the long article reaches the upper limit level stops operating. In this case, even if the building sway converges and returns to normal operation, the elevator cannot be immediately operated because a recovery operation such as inspection and component repair by a maintenance worker is required. Therefore, if the vibration amount of the long article reaches the upper limit level in all the elevators constituting the group control elevator during the control operation, the service cannot be immediately restarted even if the building sway converges, and the service has to 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 is shifted from the normal operation to the controlled operation, the distributed standby area is switched from the distributed standby area during the normal operation to the distributed standby area during the controlled operation, and the car 2 standing by in the distributed standby area during the normal operation is moved to the distributed standby area during the controlled operation. Then, for an elevator in which the car 2 has moved to the distributed standby area, particularly the priority standby area during the controlled operation, the car 2 of the elevator is caused to stand by in the priority standby area until the building sway converges without assigning a new hall call. This can suppress the expansion of the vibration of the long article of the car 2 waiting in the priority waiting area and suppress the amount of vibration of the long article from reaching the upper limit level. As a result, after the building sway converges and returns to normal operation, the elevator in which at least the car 2 is standing by in the priority standby area can be immediately operated, and a trouble that the service of the elevator 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 operating state monitoring section 21, a hall call allocating section 22, a long article vibration estimating section 23, and a distributed standby control section 24.

The operation state monitoring section 21 collects information indicating the operation state of the elevator (the current position and the traveling direction of the car 2, whether there is a hall call or a car call that is not completed in response during movement or during stoppage) from the individual control devices 10 of the elevators, and collectively monitors the operation states of the plurality of elevators constituting the group management elevator. Then, the operating state monitoring section 21 transmits information necessary for each of the hall call allocating section 22, the long article vibration estimating section 23, and the distributed standby control section 24.

The hall call allocating section 22 determines an elevator that is the most suitable for a response of a hall call among a plurality of elevators based on the hall call signal fed from the hall operating panel 15 in accordance with an operation of the hall 3 by a passenger and the operating state of each elevator fed from the operating state monitoring section 21, and allocates the hall call to the elevator. This process is called group management control. The hall call allocation unit 22 transmits a hall call response command to the individual control devices 10 that control the elevator allocated with a hall call by group management. The individual control device 10 that receives the hall call response command responds to the hall call by moving the car 2 to the floor on which the hall call is present (the floor on which the hall operation panel 15 is operated).

Here, in the present embodiment, as described above, when the operation mode of the group management elevator is shifted from the normal operation to the controlled operation and the car 2 of any one of the elevators moves into the priority waiting area, the elevator is then taken out of the group and is removed from the candidates for the elevator to which the hall call is assigned, and the group management control is performed on the remaining elevators excluding the elevator. The elevator in which the car 2 is standing by in the priority standby area returns to the group when the operation mode of the group management elevator is restored from the controlled operation to the normal operation as the building sway converges, for example.

The long article vibration estimating unit 23 estimates the vibration amount of the long article of each elevator constituting the group management elevator by real-time simulation using the vibration amount data table 31 based on the magnitude and duration of the building sway, the current position of the car 2 of each elevator, the information on the traveling direction, and the like determined based on the information from the operating state monitoring unit 21 when the building sway is detected by the building sway detector 11. Then, when it is predicted that the vibration amount of the long article of at least 1 elevator may reach the upper limit level, the long article vibration estimating unit 23 outputs a long article vibration signal. The prediction of the possibility that the vibration amount of the long article of at least 1 elevator reaches the upper limit level is, for example, as follows: when at least 1 of the plurality of elevators constituting the group management elevator moves the car 2 in response to the currently registered call, the car 2 predicts that the vibration amount of the long article reaches the floor of the upper limit level based on the magnitude of the current building sway detected by the building sway detector 11. The real-time simulation of the vibration amount of the 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 article vibration signal is output from the long article vibration estimation unit 23, the operation mode of the group management elevator is shifted from the normal operation to the control operation. Then, when the building sway converges (i.e., when the building sway is not detected by the building sway detector 11 or the magnitude of the detected building sway is lower than the reference value), the operation mode of the group management elevator is restored from the regulated operation to the normal operation.

The long article vibration estimating unit 23 outputs an operation stop signal for the elevator in a case where there is an elevator in which the vibration amount of the long article estimated by the real-time simulation has reached the upper limit level, that is, in a case where it is determined that the vibration amount of the long article has reached the upper limit level in any one of the elevators. The operation stop signal output from the long article vibration estimating unit 23 is transmitted to the individual control device 10 of the target elevator via, for example, the distributed standby control unit 24, and the operation of the elevator is stopped. In this case, since the operation of the elevator stopped needs to be resumed by a maintenance person such as inspection and component repair after the building sway converges, even if the operation mode of the group management elevator is restored from the controlled operation to the normal operation, the operation cannot be immediately resumed.

The distributed standby control unit 24 causes the car 2 of the elevator, for which the call response is completed, to be distributed and standby in the distributed standby area during the normal operation. That is, when the response to the call in a certain elevator is completed, the distributed standby control unit 24 determines whether or not there is a zone in which the car 2 does not stand by among the plurality of zones constituting the distributed standby zone in the normal operation, based on the information from the operating state monitoring unit 21 and the building data 32. Then, if there is a zone in which the car 2 is not standing by, the individual control device 10 of the elevator in which the response to the call is completed transmits a movement command to the zone, and thereby the car 2 of the elevator in which the response to the call is completed moves to the zone and stands by until a new hall call is assigned.

The distributed standby control unit 24 switches the distributed standby area from the normal operation distributed standby area to the controlled operation distributed standby area when the long article vibration signal is output from the long article vibration estimation unit 23 and the operation mode of the group management elevator is switched from the normal operation to the controlled operation. Then, the distributed standby control unit 24 determines whether or not there is an elevator waiting in the distributed standby area when the car 2 is operating normally, based on the information from the operating state monitoring unit 21 and the building data 32. Then, if there is an elevator standing by in the distributed standby zone during normal operation of the car 2, the distributed standby control section 24 transmits a movement command to the distributed standby zone during controlled operation to the individual control device 10 of the elevator, thereby moving the car 2 of the elevator to the distributed standby zone during controlled operation.

At this time, if the number of elevators waiting in the distributed waiting area is 1 when the car 2 is in normal operation, the distributed waiting control section 24 moves the car 2 of the elevator to the priority waiting area in the distributed waiting area during controlled operation. Further, if there are a plurality of elevators waiting in the distributed waiting area when the car 2 is in normal operation, the distributed waiting control section 24 moves the car 2 waiting in the area closest to the priority waiting area and moves the other cars 2 to the distributed waiting area in controlled operation other than the priority waiting area.

In addition, when the distributed standby zone is switched from the normal operation distributed standby zone to the controlled operation distributed standby zone, the distributed standby control unit 24 moves the car 2 of the elevator whose call response has first ended to the priority standby zone in the controlled operation distributed standby zone when there is no elevator whose car 2 is standing by in the distributed standby zone. Then, after the response of the call is completed, the car 2 of the remaining elevator is moved to the controlled operation other than the priority standby area while the standby area is distributed.

In addition, in some cases, the long article vibration estimating unit 23 determines that the vibration amount of the long article connected to the car 2 has reached the upper limit level during a period until the car 2 moving to the priority waiting area reaches the priority waiting area, and outputs an operation stop signal to stop the car 2. In this case, the distributed standby control unit 24 moves the car 2 of the other elevator to the priority standby area. That is, in the controlled operation, the control is performed such that at least 1 car 2 of the elevator needs to be on standby in the priority standby area.

The car 2 that has moved in a region other than the priority waiting region in the waiting region is distributed during the controlled operation, and waits in this region until a new hall call is assigned. On the other hand, the car 2 that has moved to the priority waiting area is excluded from the objects to which hall calls are assigned, and waits in the priority waiting area until the building sway converges and the operation mode of the group management elevator returns from the controlled operation to the normal operation. In this case, the distributed standby control section 24 preferably controls the display of the landing indicator 14 corresponding to the elevator in which the car 2 is standing by in the priority standby area, and causes the landing indicator 14 to display information such as "waiting in the priority standby area", for example. The distributed standby control unit 24 may notify the elevator monitoring room of identification information such as the number of the elevator in which the car 2 is standing by in the priority standby area, and turn off the operation display lamp corresponding to the elevator in which the car 2 is standing by in the priority standby area among the operation display lamps of the elevator monitoring panel for monitoring the operation state of each elevator in the elevator monitoring room.

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. 4. Fig. 4 is a flowchart showing an example of the processing procedure of the group management control device 20 in the control operation. In step S101 of fig. 4, when the building sway is detected by the building sway detector 11 and the long article vibration signal is output from the long article vibration estimation unit 23, the operation mode of the group management elevator is shifted from the normal operation to the control operation. In this case, the group management control device 20 performs the processing of step S102 to step S109 in fig. 4, and enables at least 1 elevator to be immediately operated when the building sway converges and returns to the normal operation.

When the operation mode of the group management elevator is shifted from the normal operation to the controlled operation, the group management control device 20 first switches the distributed standby area from the distributed standby area during the normal operation to the distributed standby area during the controlled operation (step S102). Then, the group management control device 20 determines whether or not there is an elevator waiting in the distributed standby area when the car 2 is operating normally (step S103), and if there is an elevator waiting in the distributed standby area when the car 2 is operating normally (step S103: YES), moves the car 2 of the elevator to the distributed standby area when the controlled operation is performed (step S104).

At this time, as described above, if the number of elevators waiting in the distributed waiting area is 1 when the car 2 is in normal operation, the group management control device 20 moves the car 2 of the elevator to the priority waiting area in the distributed waiting area during controlled operation. Further, if there are a plurality of elevators waiting in the distributed waiting area when the car 2 is in normal operation, the group management control device 20 moves the car 2 waiting in the area closest to the priority waiting area, and moves the other cars 2 to the distributed waiting area when the other cars are in controlled operation other than the priority waiting area.

On the other hand, when there is no elevator waiting in the distributed standby zone while the car 2 is operating normally (no in step S103), the group management control device 20 moves the car 2 of the elevator for which the response to the call is first ended to the priority standby zone (step S105). After the completion of the call response, the remaining elevators are moved in the standby areas in a distributed manner when the car 2 of the elevator is moved to the controlled operation other than the priority standby area.

Here, the group management control device 20 determines whether or not the vibration amount of the long article connected to the car 2 reaches the upper limit level until the car 2 moving to the priority waiting area reaches the priority waiting area (step S106). When it is determined that the vibration amount of the long article has reached the upper limit level (yes in step S106), the group management control device 20 stops the car 2 of the elevator, returns to step S103, and repeats the processing, thereby moving the cars 2 of the other elevators to the priority waiting area.

On the other hand, when the vibration amount of the long article has not reached the upper limit level and the car 2 has reached the priority waiting area (no in step S106), the group management control device 20 performs the group management control by setting the elevator in which the car 2 has moved to the priority waiting area out of the group (step S107), and waits the car 2 having moved to the priority waiting area in the priority waiting area while the building sway continues (no in step S108). As described above, the priority waiting area is an area in which the long object connected to the car 2 is particularly hard to resonate with the building sway even if the waiting area is dispersed during the controlled operation. Thus, by causing the car 2 of 1 elevator to stand by in the priority standby area during the control operation, the vibration of the long article of the elevator can be suppressed.

Then, when the building sway converges (step S108: YES), the operation mode of the group management elevators is restored from the regulated operation to the normal operation. In response to this, the group management control device 20 restores the distributed standby area from the controlled operation distributed standby area to the normal operation distributed standby area (step S109), and thereafter performs distributed standby using the normal operation distributed standby area.

As described above by way of specific example and as described in detail, in the group management elevator system according to the present embodiment, when the building sway is detected and it is predicted that the vibration amount of the long article of at least 1 elevator may reach the upper limit level, the group management control device 20 switches the distributed standby area from the distributed standby area during normal operation (first distributed standby area) to the distributed standby area during controlled operation (second distributed standby area), and moves the car 2 standing by in the distributed standby area during normal operation to the distributed standby area during controlled operation. Then, for an elevator in which the car 2 has moved to a priority waiting area where the long article is most unlikely to resonate with the building sway in the distributed waiting area during the controlled operation, the car 2 is caused to stand by in the priority waiting area until the building sway converges without assigning a new hall call. Thus, according to the present embodiment, the vibration amount of the long article can be effectively suppressed from reaching the upper limit level at least for the elevator in which the car 2 is standing by in the priority standby area, and the operation can be performed immediately after the building sway converges and returns to the normal operation. Therefore, the defect that the service of the elevator is stopped for a long time can be effectively inhibited.

< second embodiment >

Next, a second embodiment will be explained. The present embodiment is different from the first embodiment in that the operation mode of the group management elevator is shifted from the normal operation to the controlled operation. That is, in the first embodiment, when the building sway is detected by the building sway detector 11 and it is predicted that the vibration amount of the long article of at least 1 elevator is likely to reach the upper limit level (when the long article vibration estimation unit 23 outputs the long article vibration signal), the operation mode of the group management elevator is shifted from the normal operation to the controlled operation. In contrast, in the present embodiment, when the earthquake early warning signal is received, the operation mode of the group management elevator is shifted 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. Compared with the configuration of the first embodiment shown in fig. 2, the present embodiment is different in that a receiving unit 25 is added to the group management control device 20. When the earthquake early warning signal is transmitted, the receiving unit 25 receives the earthquake early warning signal and transmits the reception of the earthquake early warning signal to the distributed standby control unit 24.

In the group management control device 20 of the present embodiment, when the reception unit 25 receives the earthquake early warning signal, the distributed standby control unit 24 switches the distributed standby area from the distributed standby area during normal operation (first distributed standby area) to the distributed standby area during controlled operation (second distributed standby area), and performs the same processing as in the first embodiment described above.

That is, in step S101 shown in the flowchart of fig. 4, the group management control device 20 of the present embodiment determines whether or not the receiving unit 25 has received the earthquake early warning signal, instead of determining whether or not the long article vibration signal is output from the long article vibration estimating unit 23. When the receiver 25 receives the earthquake early warning signal, the group management control device 20 performs the processing of step S102 to step S109 in fig. 4, and enables at least 1 elevator to be immediately operated when the building sway converges and returns to the normal operation.

As described above, in the present embodiment, when the earthquake early warning signal is received, the group management control device 20 switches the distributed standby area from the distributed standby area during normal operation (first distributed standby area) to the distributed standby area during controlled operation (second distributed standby area), and moves the car 2 that is standing by in the distributed standby area during normal operation to the distributed standby area during controlled operation. Then, for an elevator in which the car 2 moves to a priority waiting area in which the long article is most likely to resonate with the building sway in the distributed waiting area during the control operation, the car 2 is made to stand by in the priority waiting area until the building sway converges without assigning a new hall call. Thus, in the present embodiment, as in the first embodiment, the vibration amount of the long article can be effectively suppressed from reaching the upper limit level at least for the elevator in which the car 2 is standing by in the priority standby area, and the operation can be performed immediately after the building sway converges and returns to the normal operation. Therefore, the defect that the service of the elevator is stopped for a long time can be effectively inhibited.

According to at least one embodiment described above, at least 1 elevator can be operated immediately after the building sway converges, and a trouble such as a service stop for a long time can be effectively suppressed.

While several embodiments of the present invention have been described above, these embodiments are presented as examples and are not intended to limit the scope of the invention. These new embodiments can be implemented in other various forms, and various omissions, substitutions, and changes can be made without departing from the spirit of the invention. These embodiments and variations thereof are included in the scope and gist of the invention, and are included in the invention described in the scope of the claims and the equivalent scope thereof.
