Description

Elevator control system

This disclosure relates to the elevator control system.

Patent Document 1 discloses an example of an elevator system. The elevator system is equipped with a seismic detector. If the acceleration detected by the seismic detector exceeds the threshold when an earthquake occurs, the elevator car will stop on the nearest floor. The car door opens when the floor on which the car is stopped is an evacuable floor.

Japanese Patent Application Laid-Open No. 2008-19043

However, in the elevator of Patent Document 1, the floor where the car is stopped may be a floor that cannot be evacuated. In addition, when the safety device is activated while driving, the car may stop in a range where there is no door between the floors. In these cases, confinement can occur. Rescue by maintenance personnel is required in the event of confinement. Here, if the maintenance personnel take a long time to arrive, it may take a long time to be rescued.

This disclosure relates to the solution of such problems. The present disclosure provides a control system capable of quicker rescue of elevator confinement caused by an earthquake.

It is provided with a propriety determination unit that determines whether or not rescue operation is possible for the confinement of the first elevator caused by an earthquake and outputs the determination result to the control device of the first elevator.

With the control system according to this disclosure, it is possible to rescue the elevator confined by the earthquake more quickly.

Embodiment 1.
FIG. 1 is a configuration diagram of a control system according to the first embodiment.

The control system 1 is a system that manages the state of the elevator 2 and controls the operation of the elevator 2 in an emergency or the like. The elevator 2 managed and controlled by the control system 1 is an example of the first elevator. The elevator 2 is connected to the network 3. The network 3 is, for example, the Internet or an intranet.

Elevator 2 is applied to building 4. Building 4 is provided in the first area. The first area is, for example, an area set in the control system 1. The first area may be, for example, an area included in a preset distance range from the building 4. Alternatively, the first area may be set based on the area in charge of the organization in charge of the maintenance of the elevator 2. The first area may be set based on administrative divisions such as municipalities. The first area may be set overlapping with other areas. Building 4 has a plurality of floors. In the building 4, a hoistway is provided over a plurality of floors. The hoistway is a space that is long in the vertical direction.

The elevator 2 includes a hoisting machine 5, a main rope 6, a basket 7, and a counterweight 8. The hoisting machine 5 is provided, for example, at the upper part or the lower part of the hoistway. Alternatively, when the machine room is provided in the building 4, the hoisting machine 5 may be provided in the machine room. The hoisting machine 5 has a sheave and a motor. The sheave of the hoisting machine 5 is connected to the rotating shaft of the motor of the hoisting machine 5. The motor of the hoisting machine 5 is a device that generates a driving force for rotating the sheave of the hoisting machine 5. The main rope 6 is wound around the sheave of the hoisting machine 5. In the hoistway, the car 7 is suspended by a main rope 6 on one side of the sheave of the hoist 5. In the hoistway, the counterweight 8 is suspended by the main rope 6 on the other side of the sheave of the hoist 5. The car 7 is a device that transports a user or the like between a plurality of floors by traveling vertically inside the hoistway. The counterweight 8 is a device that balances the load applied to the sheave of the hoisting machine 5 with the car 7 through the plurality of main ropes 6. The car 7 and the counterweight 8 travel in opposite directions on the hoistway by moving the main rope 6 by the rotation of the sheave of the hoisting machine 5. The car 7 includes a car door 9. The car door 9 is a device that opens and closes the stopped car 7 so that a user or the like can get on and off the car 7.

A plurality of safety devices 10 are provided in the elevator 2. The safety device 10 is a device that detects an event related to the operation of the elevator 2 that occurs in the elevator 2. The safety device 10a is provided on, for example, the car door 9. The safety device 10a provided on the car door 9 detects, for example, the opening and closing of the car door 9. Alternatively, another safety device 10b is provided at the end of the main rope 6. The safety device 10b provided at the end of the main rope 6 detects, for example, the vibration amplitude of the main rope 6. Here, the notation of the safety device 10 is a notation when individual safety devices such as the safety device 10a and the safety device 10b are not specified.

The elevator 2 includes a control device 11. The control device 11 is provided, for example, at the upper part or the lower part of the hoistway. Alternatively, when the machine room is provided in the building 4, the control device 11 may be provided in the machine room. The control device 11 is a device that controls the elevator 2. The control device 11 includes an operation control unit 12 and a confinement determination unit 13. The operation control unit 12 is a device that controls the operation of the elevator 2. The control of the operation of the elevator 2 includes, for example, the control of the running of the car 7. The confinement determination unit 13 is a portion that determines that confinement has occurred in the elevator 2. Here, the confinement is an event in which the car 7 is stopped in a state where the user in the car 7 cannot get off the car 7. The control device 11 is connected to the network 3 so that, for example, when confinement occurs, the confinement can be notified.

Elevator 2 is equipped with an earthquake detector 14. The seismic detector 14 is provided, for example, in a pit at the lower end of the hoistway. The earthquake detector 14 is a device that detects an earthquake occurring in the first area and outputs a detection signal to a control device 11 or the like. The seismic detector 14 has a seismograph for measuring seismic acceleration inside. In the seismic detector 14, for example, two threshold values of "low gal" and "high gal" are set in ascending order of the corresponding acceleration values. For example, when the measured seismic acceleration is smaller than "low gal", the seismic detector 14 outputs a detection signal for returning the elevator 2 to normal operation after stopping at the nearest floor and elapses for a certain period of time. For example, when the measured seismic acceleration is larger than "low gal" and smaller than "high gal", the seismic detector 14 outputs a sensing signal for causing the elevator 2 to perform a diagnostic operation. The diagnostic operation is, for example, an automatic operation for diagnosing the state of the elevator 2 accompanied by starting and stopping the hoisting machine 5 a plurality of times. For example, when the measured seismic acceleration is larger than "high gal", the seismic detector 14 outputs a detection signal for suspending the operation, assuming that an earthquake of a scale that cannot perform the diagnostic operation occurs. The seismic detector 14 of this example does not output the acceleration value measured by the internal seismograph to the outside. Therefore, in the elevator 2 of this example, an earthquake of a scale larger than "high gal" is not discriminated.

The control system 1 includes a control server 15. The control server 15 is, for example, a server computer. The control server 15 may be composed of a plurality of server computers. The control server 15 is provided in, for example, an information center. The information center is a base for collecting information on the elevator 2. The information center may be provided in a remote location in the first area where the elevator 2 is provided. The control server 15 includes an earthquake information acquisition unit 16 and a pass / fail determination unit 17.

The earthquake information acquisition unit 16 is a part that acquires earthquake scale information from an external earthquake information source of the control server 15. The seismic information source is, for example, the seismic observation network 18. The seismic observation network 18 is connected to the control server 15 through the network 3. The seismic observation network 18 is, for example, a seismograph observation network provided by a public institution or other organization. The seismic observation network 18 is, for example, K-NET (Kyoshin Net: national strong motion observation network) or KiK-net (Kiban-Kyoshin Net: basic strong motion observation network), or an observation network that provides similar information. The seismograph of the seismic observation network 18 outputs the seismic acceleration at the point where the seismograph is provided. Seismic acceleration is an example of seismic magnitude information.

The possibility determination unit 17 is a part that determines whether or not rescue operation is possible in the elevator 2 where confinement has occurred due to the earthquake. The rescue operation is an operation in which, when the elevator 2 is confined, the car 7 is driven until the user in the car 7 can get off the car 7. Rescue driving is more urgent than diagnostic driving.

Subsequently, an example of the operation of the control system 1 will be described with reference to FIG.
FIG. 2 is a flowchart showing an example of the operation of the control system according to the first embodiment.

The operation of the control device 11 starts from step S11. In step S11, the confinement determination unit 13 determines whether confinement has occurred. In the elevator 2, confinement occurs, for example, as follows due to the operation of the safety device 10. The safety device 10a operates when the car door 9 opens, for example, at a hoistway position other than the stop floor position. Alternatively, the safety device 10b operates, for example, when the amplitude of vibration of the main rope 6 is larger than a preset threshold value. When the safety device 10 is activated, an operation signal is output from the safety device 10 to the operation control unit 12. When the operation control unit 12 receives the input of the operation signal, the car 7 is urgently stopped, for example, in order to prevent the occurrence of a secondary disaster. At this time, for example, when the car 7 stops at a position of the hoistway that is not the position of the stop floor, the user cannot get off the car 7. In this way, confinement occurs in the elevator 2. When confinement occurred, the confinement determination unit 13 generated confinement based on, for example, the presence / absence of a user inside the car 7, the position where the car 7 was stopped, and the presence / absence of opening / closing of the car door 9. Is determined. In this example, the confinement determination unit 13 acquires information identifying the operated safety device 10 from the safety device 10 or the operation control unit 12. The information that identifies the safety device 10 is, for example, the identification information of the safety device 10. The confinement determination unit 13 may use the acquired information to determine the occurrence of confinement. When the confinement determination unit 13 determines that confinement has not occurred, the operation of the control device 11 proceeds to step S11 again. On the other hand, when the confinement determination unit 13 determines that confinement has occurred, the operation of the control device 11 proceeds to step S12.

In step S12, the confinement determination unit 13 reports confinement. The confinement report is output to the control server 15 through the network 3. The confinement report includes, for example, information that identifies the elevator 2 in which the confinement has occurred. The confinement report may include information that identifies the first area where the elevator 2 where the confinement has occurred is provided. In addition, the notification of confinement may include information on the cause of confinement. The information on the cause of confinement is, for example, information that identifies the activated safety device 10. Alternatively, the information on the cause of confinement may be information representing an event detected by the activated safety device 10. The information includes, for example, information indicating that the car door 9 has been opened, information indicating that the vibration of the main rope 6 has exceeded a preset threshold value, and the like. After that, the operation of the control device 11 proceeds to step S13.

On the other hand, the operation of the control server 15 starts from step S21. In step S21, the approval / disapproval determination unit 17 determines whether or not there is a notification of confinement from the elevator 2. When the pass / fail determination unit 17 determines that there is no report, the operation of the control server 15 proceeds to step S21 again. On the other hand, when the pass / fail determination unit 17 determines that there is a report, the operation of the control server 15 proceeds to step S22.

In step S22, the earthquake information acquisition unit 16 acquires earthquake scale information through the network 3 using the earthquake observation network 18 as an earthquake information source. The earthquake information acquisition unit 16 identifies the first area where the elevator 2 in which the confinement has occurred is provided, for example, based on the information included in the confinement report. The seismic information acquisition unit 16 requests the seismic observation network 18 for information on the seismic acceleration of points included in the first area. The earthquake information acquisition unit 16 acquires the earthquake acceleration at the relevant point output by the earthquake observation network 18 as information on the magnitude of the earthquake in the first region. In addition, when there is no information on the earthquake acceleration in the first area, the earthquake information acquisition unit 16 estimates the earthquake acceleration in the first area based on the information on the earthquake acceleration in the area around the first area, and the earthquake in the first area. You may obtain information on the scale of. After that, the operation of the control server 15 proceeds to step S23.

In step S23, the propriety determination unit 17 determines whether or not rescue operation is possible for the confinement caused by the earthquake in the elevator 2 based on the information acquired by the earthquake information acquisition unit 16. The propriety determination unit 17 determines whether or not the rescue operation is possible by comparing the acquired acceleration value with the rescue threshold value when the acceleration information is acquired as the earthquake scale information. The rescue threshold is, for example, a preset threshold corresponding to an acceleration greater than "high gal". That is, the rescue threshold corresponds to an earthquake of a scale that can be performed by the rescue operation for confinement, although the diagnostic operation for checking the device of the elevator 2 is not performed. The rescue threshold may be set for each confinement factor. That is, the feasibility determination unit 17 may determine whether or not the rescue operation is possible by using the rescue thresholds having different values according to the information on the confinement factors included in the confinement report. The possibility determination unit 17 determines that the rescue operation is possible when the acquired acceleration value is smaller than the rescue threshold value. On the other hand, the propriety determination unit 17 determines that the rescue operation is impossible when the acquired acceleration value is equal to or greater than the rescue threshold value. The pass / fail determination unit 17 outputs the determination result to the control device 11 through the network 3. After that, the operation of the control server 15 proceeds to step S24.

In step S24, the control server 15 determines whether the rescue operation is possible based on the determination result of the availability determination unit 17. When it is determined that the rescue operation is possible, the operation of the control server 15 proceeds to step S21. On the other hand, if it is not determined that the rescue operation is possible, the operation of the control server 15 proceeds to step S25.

In step S25, the control server 15 arranges for the dispatch of maintenance personnel to the elevator 2 where the confinement has occurred for rescue. The control server 15 may make arrangements, for example, by notifying an information terminal possessed by a maintenance worker who can be dispatched to a dispatch request. The control server 15 may select a maintenance person who can be dispatched based on information such as the distance from the elevator 2 where the confinement has occurred. After that, the operation of the control server 15 ends.

Here, the control device 11 receives the determination result of whether or not the rescue operation is possible from the control server 15 before the step S13.

In step S13, the operation control unit 12 determines whether or not rescue operation is possible based on the determination result acquired from the control server 15. When the rescue operation is possible, the operation of the control device 11 proceeds to step S14. On the other hand, when the rescue operation is not possible, the operation of the control device 11 proceeds to step S15.

In step S14, the operation control unit 12 performs a rescue operation for confinement. The rescue operation is, for example, an operation in which the car 7 is driven from the position of the hoistway where the user cannot get off the car 7 to the position of the stop floor. In the rescue operation, the number of times the hoisting machine 5 is started and stopped may be limited. The upper limit of the number of start and stop is, for example, once. When the number of starts and stops exceeds the upper limit, the operation control unit 12 may request the control server 15 to dispatch a maintenance person through the network 3 because the rescue operation has failed. After the car 7 has traveled from the car 7 to a position where the user can get off by the rescue operation, the operation control unit 12 opens the car door 9 of the car 7. As a result, the user can get off the car 7 and evacuate. After that, the operation of the control device 11 ends.

In step S15, the operation control unit 12 stands by without performing a rescue operation for confinement. In this example, maintenance personnel are dispatched by the control server 15 for rescue. The control device 11 may notify the user that the dispatch of maintenance personnel is arranged by, for example, a notification device provided in the car 7. After that, the operation of the control device 11 ends.

As described above, the control system 1 according to the first embodiment includes an earthquake information acquisition unit 16 and a feasibility determination unit 17. The earthquake information acquisition unit 16 acquires information on the magnitude of an earthquake in the first area from an earthquake information source. The first area is the area where the first elevator is installed. The propriety determination unit 17 determines whether or not the rescue operation is possible for the confinement of the first elevator based on the information acquired by the earthquake information acquisition unit 16. Confinement is caused by an earthquake. The approval / disapproval determination unit 17 outputs the determination result to the control device 11 of the first elevator.

When a wide area disaster such as an earthquake occurs, confinement may occur in a plurality of elevators 2. At this time, if the maintenance staff is dispatched to rescue all the confinement that has occurred, an elevator 2 that takes time for the maintenance staff to arrive may occur. On the other hand, the control system 1 outputs a determination result indicating whether or not the rescue operation is possible to the control device 11 of the elevator 2. Therefore, the control device 11 can perform the rescue operation without waiting for the arrival of the maintenance staff based on the determination result from the control system 1. In the elevator 2 capable of rescue operation, quick rescue is performed for confinement. Further, since the number of confinement cases requiring rescue by the maintenance staff is reduced, the waiting time until the arrival of the maintenance staff can be shortened even in the elevator 2 where the rescue operation is impossible. In this way, the control system 1 can rescue the elevator 2 caused by the earthquake more quickly. Further, the control system 1 outputs a determination result indicating that the rescue operation is impossible when an earthquake of a scale that the rescue operation cannot be performed occurs. As a result, the occurrence of a secondary disaster due to forced rescue operation is prevented. In addition, whether or not rescue operation is possible is determined by the ATC center based on the information acquired by the ATC center from an external seismic information source. Therefore, even for the elevator 2 in which the threshold value for determining the propriety of the rescue operation cannot be newly set in the seismic detector 14, the feasibility of the rescue operation for confinement is appropriately determined.

Further, the propriety determination unit 17 outputs the determination result of whether or not the rescue operation is possible for the confinement of the first elevator to the control device 11 after receiving the notification of confinement from the first elevator.

As a result, the propriety determination unit 17 does not transmit the determination result of whether or not rescue operation is possible to the elevator 2 that has not been notified of confinement. Therefore, since the determination result is not transmitted to the elevator 2 in which the confinement has not occurred, unnecessary communication is not performed.

In addition, the earthquake information acquisition unit 16 acquires the earthquake acceleration in the first region as information on the scale of the earthquake, using the earthquake observation network 18 that outputs the earthquake acceleration as the earthquake information source.

In general, in the elevator 2, the response to an earthquake such as the propriety of diagnostic operation is often determined based on the acceleration. Since the propriety determination unit 17 makes a determination based on the acceleration, it is possible to determine whether or not the rescue operation is possible based on a standard consistent with other responses to the earthquake.

When the report from the first elevator includes information on the cause of confinement, the propriety determination unit 17 may determine whether or not the rescue operation is possible for the confinement of the first elevator according to the factor.

The possible secondary disasters may differ depending on the event that caused the confinement. Therefore, the magnitude of the earthquake that can be rescued may differ depending on the event that caused the confinement. Here, the propriety determination unit 17 determines whether or not the rescue operation is possible based on the criteria according to the factors. Therefore, the propriety of rescue operation for confinement is appropriately determined. In addition, since it is not necessary to set the criteria for whether or not the rescue operation is possible on the safe side excessively, the rescue operation becomes easier to be performed. Therefore, rescue for the confinement of the elevator 2 can be performed more quickly.

Further, when the area corresponding to the point where the seismograph is provided is set in the seismic observation network 18, the first area may be set based on the area.

Further, the earthquake information acquisition unit 16 may use the second elevator provided in the first area as the earthquake information source. The second elevator is another elevator of the first elevator in which the confinement has occurred. The second elevator is equipped with a seismograph that outputs the acceleration value to the outside. That is, the earthquake information acquisition unit 16 acquires the acceleration output by the seismograph of the second elevator as the earthquake scale information, using the second elevator provided in the first area as the earthquake information source.

In the first area, the seismic observation network 18 may not be constructed. Even in this case, if an elevator equipped with a seismograph that outputs acceleration is provided, the control system 1 can determine whether or not rescue operation is possible for the confinement that occurs in the elevator 2 in the area.

Further, the propriety determination unit 17 may determine whether or not the rescue operation is possible for the confinement of the first elevator based on at least one information of the speed or the displacement due to the earthquake. The information is calculated by time-integrating the seismic acceleration or acceleration acquired by the seismic information acquisition unit 16 by the feasibility determination unit 17.

Depending on the equipment of the elevator 2, it may be more affected by speed or displacement than seismic acceleration or acceleration. In this case, since the propriety of the rescue operation is determined by the speed or the displacement, the propriety of the rescue operation for confinement is appropriately determined.

Further, the earthquake information acquisition unit 16 may use the third elevator provided in the first area as the earthquake information source. The third elevator is another elevator of the first elevator in which the confinement has occurred. The third elevator outputs a report indicating an event caused by the earthquake to the control server 15 through, for example, the network 3. The event caused by the earthquake is, for example, a failure of equipment in the third elevator. Here, the events that occur in the third elevator differ depending on the magnitude of the earthquake in the first area. For example, the type of equipment that fails and the degree of failure differ depending on the magnitude of the earthquake. Therefore, the pass / fail determination unit 17 can estimate the scale of the earthquake that occurred in the first area based on the event that occurred in the third elevator, for example, by referring to a table. The propriety determination unit 17 determines whether or not the rescue operation is possible for the confinement of the first elevator based on the estimated magnitude of the earthquake.

In the first area, there are cases where an elevator equipped with a seismograph that outputs acceleration is not installed. Even in this case, if an elevator that reports an event caused by an earthquake is provided, the control system 1 can determine whether or not rescue operation is possible for the confinement that occurs in the elevator 2 in the area.

Further, when the control device 11 receives the input of the determination result from the control server 15, it may determine whether or not to perform the rescue operation together with the current operating state of the safety device 10. The safety device 10 may be restored after being activated once. For example, when the safety device 10a detects the opening / closing of the car door 9, the car door 9 may be slightly opened by the vibration and then closed again by the vibration. In this way, if the car door 9 is closed, rescue operation may be possible even after the safety device 10 has been activated once. In such a case, the control device 11 can more appropriately determine whether or not the rescue operation is possible based on the determination result from the control server 15 and the operating state of the safety device 10.

In addition, the earthquake information acquisition unit 16 acquires information on the magnitude of the earthquake from the earthquake information source after receiving the notification of confinement from the elevator 2. Therefore, since information on earthquakes in areas where confinement has not occurred is not collected, unnecessary communication is not performed. The earthquake information acquisition unit 16 may acquire information on the magnitude of the earthquake from the earthquake information source before receiving the notification of confinement from the elevator 2. By collecting the information in advance, the earthquake information acquisition unit 16 can promptly reply to the report of confinement with the determination result.

Further, the propriety determination unit 17 determines whether or not the rescue operation is possible after receiving the notification of confinement from the elevator 2. Therefore, since it is not determined whether or not the rescue operation is possible for the elevator 2 in which the confinement has not occurred, unnecessary processing related to the determination is not performed. The possibility determination unit 17 may determine whether or not the rescue operation is possible before receiving the notification of confinement from the elevator 2. The earthquake information acquisition unit 16 can promptly reply to the report of confinement by determining whether or not the rescue operation is possible.

Further, the control server 15 may be provided in the building 4 in which the elevator 2 is provided. A part or all of the functions such as the earthquake acquisition unit and the pass / fail determination unit 17 of the control system 1 may be mounted on the elevator 2 itself.

Subsequently, an example of the hardware configuration of the main part of the control system 1 will be described with reference to FIG.
FIG. 3 is a hardware configuration diagram of a main part of the control system according to the first embodiment.

Each function of the control system 1 can be realized by a processing circuit. The processing circuit includes at least one processor 1b and at least one memory 1c. The processing circuit may include at least one dedicated hardware 1a with or as a substitute for the processor 1b and the memory 1c.

When the processing circuit includes the processor 1b and the memory 1c, each function of the control system 1 is realized by software, firmware, or a combination of software and firmware. At least one of the software and firmware is written as a program. The program is stored in the memory 1c. The processor 1b realizes each function of the control system 1 by reading and executing the program stored in the memory 1c.

The processor 1b is also referred to as a CPU (Central Processing Unit), a processing device, an arithmetic unit, a microprocessor, a microcomputer, and a DSP. The memory 1c is composed of, for example, a non-volatile or volatile semiconductor memory such as a RAM, a ROM, a flash memory, an EPROM, or an EEPROM, a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, a DVD, or the like.

When the processing circuit includes dedicated hardware 1a, the processing circuit is realized by, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof.

Each function of the control system 1 can be realized by a processing circuit. Alternatively, each function of the control system 1 can be collectively realized by a processing circuit. For each function of the control system 1, a part may be realized by the dedicated hardware 1a, and the other part may be realized by software or firmware. As described above, the processing circuit realizes each function of the control system 1 by the dedicated hardware 1a, software, firmware, or a combination thereof.

Embodiment 2.
The differences between the second embodiment and the examples disclosed in the first embodiment will be described in particular detail. As for the features not described in the second embodiment, any of the features disclosed in the first embodiment may be adopted.

FIG. 4 is a flowchart showing an example of the operation of the control system according to the second embodiment.
Here, in the control system 1 according to the first embodiment and the control system 1 according to the second embodiment, the operations in the steps with the same number may be the same as each other. The steps with the same number are steps S11, S13 to S15, S22, S23, and S25.

The operation of the control server 15 starts from step S26. In step S26, the earthquake information acquisition unit 16 determines whether an earthquake has occurred in any of the areas targeted by the control server 15. The earthquake information acquisition unit 16 determines whether or not an earthquake has occurred, for example, by monitoring the information of the earthquake observation network 18. When the earthquake information acquisition unit 16 determines that no earthquake has occurred, the operation of the control server 15 proceeds to step S26 again. When the earthquake information acquisition unit 16 determines that an earthquake has occurred, the operation of the control server 15 proceeds to step S22.

In step S22, the earthquake information acquisition unit 16 acquires earthquake scale information through the network 3 using the earthquake observation network 18 as an earthquake information source. The seismic information acquisition unit 16 requests the seismic observation network 18 to provide information on the seismic acceleration of points included in the area where the earthquake has occurred. The earthquake information acquisition unit 16 acquires the earthquake acceleration at the relevant point output by the earthquake observation network 18 as information on the magnitude of the earthquake. After that, the operation of the control server 15 proceeds to step S23.

In step S23, the propriety determination unit 17 determines whether or not rescue operation is possible for the confinement caused by the earthquake in the elevator 2 based on the information acquired by the earthquake information acquisition unit 16. The pass / fail determination unit 17 outputs the determination result to the control device 11 through the network 3. After that, the operation of the control server 15 proceeds to step S27.

On the other hand, the operation of the control device 11 starts from step S11. In step S11, the confinement determination unit 13 determines whether confinement has occurred. When the confinement determination unit 13 determines that confinement has not occurred, the operation of the control device 11 proceeds to step S11 again. On the other hand, when the confinement determination unit 13 determines that confinement has occurred, the operation of the control device 11 proceeds to step S13.

In step S13, the operation control unit 12 determines whether or not rescue operation is possible based on the determination result acquired from the control server 15 prior to step S13. When the rescue operation is possible, the operation of the control device 11 proceeds to step S14. On the other hand, when the rescue operation is not possible, the operation of the control device 11 proceeds to step S16.

In step S14, the operation control unit 12 performs a rescue operation for confinement. After that, the operation of the control device 11 ends.

In step S16, the operation control unit 12 requests the control server 15 to dispatch a maintenance worker for rescue from the confinement through the network 3. After that, the operation of the control device 11 proceeds to step S15.

In step S15, the operation control unit 12 stands by without performing a rescue operation for confinement. In this example, the control server 15 is requested to dispatch maintenance personnel for rescue. The control device 11 may notify the user that the maintenance staff is requested to be dispatched by, for example, a notification device provided in the car 7. After that, the operation of the control device 11 ends.

Here, the control server 15 may receive a request for dispatching a maintenance worker from the control device 11 before step S27.

In step S27, the control server 15 determines whether the control device 11 of the elevator 2 in which the confinement has occurred requests the dispatch of a maintenance worker for rescue. If the dispatch of maintenance personnel is not requested, the operation of the control server 15 proceeds to step S26. On the other hand, when the dispatch of maintenance personnel is requested, the operation of the control server 15 proceeds to step S25.

In step S25, the control server 15 arranges the dispatch of maintenance personnel for the rescue of the elevator 2 in which the confinement has occurred. After that, the operation of the control server 15 ends.

As described above, the feasibility determination unit 17 of the control system 1 according to the second embodiment determines whether or not the rescue operation is possible for the confinement of the first elevator regardless of whether or not there is a notification of confinement from the first elevator. The result is output to the control device 11.

The control system 1 outputs in advance whether or not rescue operation is possible to the control device 11 when confinement may occur due to an earthquake. Therefore, if the determination result of whether or not the rescue operation is possible is received, the control device 11 can promptly perform the rescue operation when the confinement occurs.

The control system according to this disclosure can be applied to elevators where confinement may occur due to an earthquake.
