Description

The present disclosure relates to a central elevator management device and an elevator management system.

Patent Document 1 discloses an example of an elevator management system.

In the elevator, a stop operation to the evacuation floor is performed based on the predicted arrival time and the maximum acceleration.

Japanese Unexamined Patent Publication No. 2007-161378

However, in the management system of Patent Document 1, the arrival time and the maximum acceleration of the seismic wave are predicted by the calculation based on the position of the epicenter and the position of the building. On the other hand, the effect of an earthquake on an elevator can change not only by the position of the building to which the elevator is applied but also by the structure of the building itself. If there is an error in predicting the impact of an earthquake on the elevator, there is a possibility that an erroneous judgment will occur as to whether or not evacuation such as stopping at the evacuation floor is necessary. When the necessity of evacuation is erroneously determined, the elevator user may be trapped in the car.

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

The management system 1 is a system for remotely managing a plurality of elevators 2. Remote management in the management system 1 includes response to an earthquake in each elevator 2. Remote management in the management system 1 is performed based on an earthquake early warning such as an earthquake early warning.

The Earthquake Early Warning is an earthquake early warning distributed by a distribution organization 3 such as the Japan Meteorological Agency or a distribution company when an earthquake occurs. The Earthquake Early Warning includes information on the epicenter of an earthquake that has occurred, as well as information on preset values of the intensity of shaking caused by the earthquake for each area, and information on the predicted time of arrival of seismic waves in the area. The epicenter information of an earthquake includes information on the location of the epicenter of the earthquake, the time of occurrence of the earthquake, and the intensity of the epicenter of the earthquake. The location of the epicenter includes, for example, the latitude and longitude of the epicenter, as well as the depth. The intensity of the epicenter is expressed, for example, by magnitude. Information on the strength of shaking is, for example, the seismic intensity class. The information on the strength of the shaking included in the earthquake early warning may be the maximum acceleration or the like.

In the management system 1, a plurality of areas are preset. A plurality of elevators 2 remotely managed by the management system 1 are provided in any of the areas set in the management system 1. The area set in the management system 1 is, for example, the area set in the Earthquake Early Warning. In this example, the area A, the area B, and the like are set as the areas of the management system 1.

The elevator 2 remotely controlled by the management system 1 is applied to, for example, a building 4 having a plurality of floors. In the building 4, the hoistway 5 of the elevator 2 is provided. The hoistway 5 is a vertically long space spanning a plurality of floors. Each elevator 2 includes a hoist 6, a main rope 7, a car 8, a counterweight 9, an earthquake detector 10, a control panel 11, and a remote control device 12.

The hoisting machine 6 includes a motor that generates a driving force and a sheave that is rotated by the driving force generated by the motor. The hoisting machine 6 is arranged, for example, at the upper part or the lower part of the hoistway 5. Alternatively, when the machine room is provided in the elevator 2, for example, above the hoistway 5, the hoisting machine 6 may be arranged in the machine room.

The main rope 7 is a rope that supports the loads of the car 8 and the counterweight 9 in the hoistway 5. The main rope 7 is wound around the sheave of the hoist 6. The main rope 7 receives the load of the car 8 on one side of the sheave of the hoist 6. The main rope 7 receives the load of the counterweight 9 on the other side of the sheave of the hoist 6.

The car 8 is a device that transports the user of the elevator 2 between a plurality of floors by traveling in the hoistway 5 in the vertical direction. The counterweight 9 is a device that balances the load applied to both sides of the sheave of the hoist 6 with the car 8. The car 8 and the counterweight 9 travel in the hoistway 5 in opposite directions by the driving force generated by the motor of the hoisting machine 6.

The seismic detector 10 is a device that detects a seismic wave such as a P wave (Primary Wave) or an S wave (Secondary Wave) of an earthquake. The seismic detector 10 is arranged, for example, in a pit at the bottom of the hoistway 5. Alternatively, if a machine room is provided, the seismic detector 10 may be arranged in the machine room. The seismic detector 10 is connected to the control panel 11 so as to be able to output a sensing signal when, for example, detecting a seismic wave having an amplitude larger than a preset size.

The control panel 11 is a device that controls the operation of the elevator 2 provided with the control panel 11. The operation of the elevator 2 includes, for example, traveling of the car 8. The control panel 11 is arranged, for example, in the upper part or the lower part of the hoistway 5. Alternatively, when the machine room is provided, the control panel 11 may be arranged in the machine room. The control panel 11 shifts to the control operation, for example, when receiving a detection signal output from the seismic detector 10. The control operation may include, for example, a diagnostic operation for automatically diagnosing the influence of an earthquake on the elevator 2.

The remote control device 12 is a device that remotely manages the elevator 2 provided with the remote control device 12. The remote control device 12 causes the elevator 2 to, for example, evacuate in response to the occurrence of an earthquake and shift to control operation. The remote control device 12 is connected to the control panel 11 so as to be able to manage the operation of the elevator 2. The remote management device 12 is included in the management system 1.

At least one of the remote control devices 12 of the elevator 2 is equipped with a function of receiving an Earthquake Early Warning distributed from the distribution organization 3 to the area where the elevator 2 is installed. The remote management device 12 is equipped with a function of transferring the epicenter information included in the Earthquake Early Warning in the management system 1 when receiving the Earthquake Early Warning. At this time, the remote control device 12 may transfer the received Earthquake Early Warning as it is.

The management system 1 includes a central management device 13. The central management device 13 is connected to the remote management device 12 of each elevator 2 through a communication network such as the Internet or a telephone line network. The central management device 13 includes a history storage unit 14, an input unit 15, a distribution unit 16, and an analysis unit 17.

The history storage unit 14 is a portion for accumulating and storing history information. The history information is information in which the epicenter information of an earthquake that has occurred in the past and the arrival information of the seismic wave of the earthquake in each elevator 2 are associated with each other. The seismic wave arrival information includes information on whether or not the seismic wave is detected by the seismic detector 10 provided in the elevator 2 and information on the detection time when the seismic detector 10 detects the seismic wave. Whether or not the seismic wave is detected by the seismic detector 10 corresponds to, for example, whether or not the detection signal is output to the control panel 11. In this example, the historical information includes information on the strength of the shaking caused by the earthquake. Here, the information on the strength of the shaking is, for example, a predicted value of the strength of the shaking by the earthquake early warning such as the Earthquake Early Warning delivered to the area where each elevator 2 is provided in accordance with the occurrence of the earthquake.

The input unit 15 is a part that receives the transfer of the epicenter information included in the Earthquake Early Warning from the remote management device 12 that has received the Earthquake Early Warning. In this example, the input unit 15 is equipped with a function of collecting the arrival information of the seismic wave of the earthquake from the remote control device 12 of each elevator 2 after the earthquake has converged. Here, the arrival information is stored as an operation log in, for example, the remote control device 12 or the control panel 11 of each elevator 2. The arrival information collected by the input unit 15 is stored in the history storage unit 14 as history information.

The distribution unit 16 is a part that distributes information such as an operation command for performing remote control to each elevator 2.

The analysis unit 17 is a unit that analyzes whether or not each elevator 2 needs to respond to the earthquake based on the epicenter information of the earthquake received by the input unit 15. The result of the analysis by the analysis unit 17 is distributed to each elevator 2 by the distribution unit 16. In this example, the result of the analysis by the analysis unit 17 is delivered to the remote control device 12 of each elevator 2. The analysis unit 17 includes a prediction unit 18, a generation unit 19, and a calculation unit 20.

The prediction unit 18 is a part that predicts the arrival of the seismic wave of the newly generated earthquake to each elevator 2. The prediction unit 18 makes a prediction when the epicenter information of a newly generated earthquake is input to the input unit 15. The prediction by the prediction unit 18 is performed based on the epicenter information input to the input unit 15 and the history information stored in the history storage unit 14. The prediction by the prediction unit 18 is, for example, a prediction by a machine learning method. In this example, the prediction unit 18 performs learning in advance based on the history information. The learning performed by the prediction unit 18 is, for example, supervised learning in which history information is used as teacher data and epicenter information is input and arrival information is output. The prediction unit 18 predicts, for example, whether or not a seismic wave sensed by the seismic detector 10 has arrived as arrival information, and the arrival time of the seismic wave. The arrival time of a seismic wave is predicted as a relative time based on, for example, the generation time of the epicenter information.

The generation unit 19 is a unit that generates an evacuation command for each elevator 2 based on the prediction result of arrival by the prediction unit 18. The evacuation command is an operation command for causing each elevator 2 to perform evacuation processing. The generation unit 19 generates an evacuation command for the elevator 2 predicted by the prediction unit 18 that the seismic wave detected by the seismic detector 10 will arrive, for example. The generation unit 19 generates an evacuation command including a predicted value of the arrival time of the seismic wave. The evacuation command generated by the generation unit 19 is distributed to each elevator 2 by the distribution unit 16.

The generation and distribution of the evacuation command is performed, for example, as follows. When a new earthquake occurs, the remote control device 12 of any elevator 2 in area A receives the earthquake early warning delivered to area A. At this time, the remote control device 12 transfers the epicenter information of the earthquake to the input unit 15 of the central control device 13. The prediction unit 18 predicts the arrival of the seismic wave of the earthquake for each of the elevators 2 provided in the area A based on the result of the learning performed in advance. Based on the prediction result by the prediction unit 18, the generation unit 19 generates an evacuation command for the elevator 2 provided in the area A where the arrival of the seismic wave detected by the seismic detector 10 is predicted. The distribution unit 16 distributes the evacuation command to the elevator 2 in which the evacuation command is generated among the elevators 2 provided in the area A. In this example, the distribution unit 16 distributes the evacuation command shortly after the generation of the evacuation command. When the processing time in the central control device 13 required from the input of the epicenter information of the newly generated earthquake to the generation of the evacuation command is sufficiently short, the distribution by the distribution unit 16 is performed before the shaking due to the earthquake occurs in the area A. Will be done. The remote management device 12 of the elevator 2 that has received the evacuation command delivered from the central management device 13 causes the control panel 11 to perform the evacuation process.

The calculation unit 20 is a part that calculates a threshold value for the strength of shaking due to an earthquake for each elevator 2. The threshold value calculated by the calculation unit 20 is used in each elevator 2 to determine whether or not evacuation is necessary. The calculation unit 20 calculates the threshold value by, for example, a binary classification method. In the binary classification method, for example, information on the predicted tremor intensity in the earthquake included in the history information of the earthquakes that have occurred in the past is used for the seismic wave of the earthquake by the seismic detector 10 provided in the elevator 2. It is a method of classifying according to the presence or absence of detection. The threshold value calculated by the calculation unit 20 is distributed to each elevator 2 by the distribution unit 16.

Calculation and distribution of the threshold value are performed, for example, as follows. The calculation unit 20 starts the calculation of the threshold value, for example, at the timing of the threshold value calculation set in advance. The timing of threshold calculation is, for example, once in a preset period. The distribution unit 16 distributes the threshold value calculated by the calculation unit 20 to each elevator 2. The distribution by the distribution unit 16 is performed, for example, when the input unit 15 has not received the epicenter information. When receiving the earthquake early warning of a newly generated earthquake, the remote management device 12 of the elevator 2 that has received the threshold value delivered from the central management device 13 determines the necessity of the evacuation process based on the delivered threshold value. The remote control device 12 determines that the evacuation process is necessary when, for example, the predicted value of the shaking strength included in the Earthquake Early Warning exceeds the threshold value delivered in advance. At this time, the remote management device 12 causes the control panel 11 to perform the operation of the evacuation process.

FIG. 2 is a flowchart showing an example of the operation of the central management device 13 according to the first embodiment.

In step S20, the central management device 13 determines whether the input unit 15 has received the epicenter information of the newly generated earthquake.

When the determination result is No, the operation of the central management device 13 proceeds to step S24.

In step S21, the prediction unit 18 predicts the arrival of the seismic wave of the earthquake based on the epicenter information of the newly generated earthquake received by the input unit 15 and the history information stored in the history storage unit 14.

In step S24, the calculation unit 20 determines whether it is time to calculate the threshold value. When the determination result is Yes, the operation of the central management device 13 proceeds to step S25.

In step S25, the calculation unit 20 calculates a threshold value used for determining the necessity of evacuation for each elevator 2 based on the history information stored in the history storage unit 14. After that, the operation of the central management device 13 proceeds to step S26.

In step S26, the distribution unit 16 distributes the threshold value calculated by the calculation unit 20 to each elevator 2. After that, the operation of the central management device 13 proceeds to step S20.

FIG. 3 is a flowchart showing an example of the operation of the remote management device 12 according to the first embodiment.

In step S30, the remote management device 12 determines whether or not the evacuation command has been received from the central management device 13. If the determination result is No, the operation of the remote management device 12 proceeds to step S31. When the determination result is Yes, the operation of the remote management device 12 proceeds to step S34.

In step S31, the remote management device 12 determines whether or not an earthquake early warning such as an earthquake early warning has been received from the distribution organization 3. If the determination result is No, the operation of the remote management device 12 proceeds to step S30. When the determination result is Yes, the operation of the remote management device 12 proceeds to step S32. The remote management device 12 not equipped with the function of receiving the earthquake early warning may proceed to the operation of step S30 assuming that the earthquake early warning has not been received without making the determination in step S31.

In step S32, the remote control device 12 transfers the epicenter information included in the received Earthquake Early Warning to the central control device 13. After that, the operation of the remote management device 12 proceeds to step S33.

In step S33, the remote control device 12 determines whether the predicted value of the shaking strength included in the received Earthquake Early Warning is larger than the threshold value delivered from the central control device 13. If the determination result is No, the operation of the remote management device 12 proceeds to step S30. When the determination result is Yes, the operation of the remote management device 12 proceeds to step S34.

In step S34, the remote management device 12 causes the control panel 11 to perform an evacuation operation. After that, the operation of the remote management device 12 ends.

FIG. 4 is a flowchart showing an example of the operation of the control panel 11 according to the first embodiment.
FIG. 4 shows the operation of the control panel 11 regarding the operation of evacuation.

In step S40, the control panel 11 invalidates the registered landing call. After that, the operation of the control panel 11 proceeds to step S41.

In step S41, the control panel 11 determines whether the car 8 is running. If the determination result is Yes, the operation of the control panel 11 proceeds to step S42. If the determination result is No, the operation of the control panel 11 proceeds to step S46.

In step S42, the control panel 11 determines whether the evacuation floor is in the traveling direction of the car 8.

If the determination result is No, the operation of the control panel 11 proceeds to step S45.

In step S43, the control panel 11 determines whether the traveling car 8 can stop at the evacuation floor by the predicted arrival time of the seismic wave of the earthquake. Here, when the predicted value of the arrival time by the prediction unit 18 is delivered to the remote management device 12 together with the evacuation command or the like, the control panel 11 makes a determination based on the predicted value by the prediction unit 18. Alternatively, when the evacuation is performed by the Earthquake Early Warning or the like without using the evacuation command, the control panel 11 makes a determination based on the predicted value of the arrival time included in the Earthquake Early Warning. If the determination result is Yes, the operation of the control panel 11 proceeds to step S44. If the determination result is No, the operation of the control panel 11 proceeds to step S45.

In step S44, the control panel 11 stops the running car 8 on the evacuation floor. After that, the operation of the control panel 11 proceeds to step S46.

In step S45, the control panel 11 stops the running car 8 at the nearest floor. After that, the operation of the control panel 11 proceeds to step S46.

In step S46, the control panel 11 starts a pause operation. The pause operation is an operation of the elevator 2 that is continuously performed for a preset pause time. In the hibernation operation, the car 8 is stopped on any floor. After that, the operation of the control panel 11 proceeds to step S47.

In step S47, the control panel 11 determines whether the seismic detector 10 has detected a seismic wave within the pause time. If the determination result is Yes, the operation of the control panel 11 proceeds to step S48. If the determination result is No, the operation of the control panel 11 proceeds to step S49.

In step S48, the control panel 11 shifts to the control operation. After that, the operation of the control panel 11 regarding the operation of evacuation ends.

In step S49, the control panel 11 is restored to normal operation. After that, the operation of the control panel 11 regarding the operation of evacuation ends.

As described above, the management system 1 according to the first embodiment includes a central management device 13 and a plurality of remote management devices 12. The central management device 13 includes a history storage unit 14, an input unit 15, a prediction unit 18, a generation unit 19, and a distribution unit 16. The history storage unit 14 accumulates and stores history information for each elevator 2 provided in a preset area. The history information is information in which the epicenter information of an earthquake that has occurred in the past and the arrival information of the seismic wave of the earthquake in each elevator 2 are associated with each other. The input unit 15 receives input of the epicenter information of the earthquake from the remote management device 12 that receives the earthquake early warning such as the earthquake early warning when a new earthquake occurs. The earthquake early warning is delivered to the area where a plurality of elevators 2 are provided before the shaking caused by the earthquake occurs. The earthquake early warning includes the epicenter information of the earthquake. The prediction unit 18 predicts the arrival of the seismic wave of the earthquake in each elevator 2 when the epicenter information of the newly generated earthquake is input to the input unit 15. The prediction by the prediction unit 18 is performed based on the epicenter information of the earthquake and the history information stored in the history storage unit 14. The generation unit 19 generates an evacuation command for each elevator 2 to perform an evacuation process based on the prediction result of arrival by the prediction unit 18. The distribution unit 16 distributes the evacuation command generated by the generation unit 19 for the newly generated earthquake to each elevator 2 before the shaking caused by the earthquake occurs in the area where the plurality of elevators 2 are provided. At least one of the plurality of remote control devices 12 is provided in any of the elevators 2. When the remote management device 12 provided in any of the elevators 2 receives the evacuation command from the central management device 13, the elevator 2 is made to evacuate.

With such a configuration, the evacuation command is generated based on the prediction result using the past arrival information. Since historical information about past earthquakes is used, predictions are made that incorporate the effects of structures such as underground rocks from the epicenter to the position where the elevator 2 is installed. In addition, since the prediction is not made by calculating the propagation of seismic waves, the prediction result can be obtained quickly. Therefore, the evacuation command based on the arrival prediction will be delivered before the arrival of the seismic wave. Since the evacuation command is delivered before the shaking caused by the newly generated earthquake occurs in the elevator 2, the evacuation of the car 8 to the evacuation floor or the nearest floor can be performed more reliably. Therefore, the occurrence of confinement due to the shaking of the earthquake can be more reliably avoided.

Further, the history storage unit 14 stores information on the location of the epicenter of the earthquake, the time of occurrence of the earthquake, and the intensity of the epicenter of the earthquake as the epicenter information of the earthquake. The history storage unit 14 determines whether or not the seismic wave of the earthquake is detected by the seismic detector 10 provided in the elevator 2 as the arrival information of the seismic wave of the earthquake in each elevator 2, and the seismic wave of the earthquake is detected by the seismic detector 10. The information of the detection time when is detected is stored.

With such a configuration, it becomes possible to make a prediction that incorporates the influence of the structure of the building 4 to which the elevator 2 is applied. Therefore, since the necessity of evacuation is determined with higher accuracy, the occurrence of confinement due to the shaking of the earthquake can be more reliably avoided.

Further, the central management device 13 includes a calculation unit 20. The history storage unit 14 includes information on the strength of shaking predicted in a past earthquake and stores it in the history information of the earthquake. When the earthquake early warning delivered when a new earthquake occurs includes the predicted value of the shaking strength due to the earthquake, the input unit 15 is subjected to the shaking caused by the earthquake from the remote management device 12 that received the earthquake early warning. Receives the input of the predicted value of the strength of. The calculation unit 20 calculates a threshold value for the strength of shaking due to an earthquake for each elevator 2. The threshold value calculated here is used to determine the necessity of evacuation when each elevator 2 receives an earthquake early warning. The calculation unit 20 calculates the threshold value based on the history information. The distribution unit 16 distributes the threshold value calculated by the calculation unit 20 to each elevator 2 in advance.

With such a configuration, the result of the analysis by the analysis unit 17 is distributed to the remote management device 12 of each elevator 2 in advance as a calculated threshold value. As a result, when the earthquake early warning is received in each elevator 2, the response based on the analysis result based on the historical information can be promptly performed. Further, since the analysis result is distributed before the occurrence of the earthquake, even if a communication failure or the like occurs due to the earthquake, the response based on the analysis result based on the history information can be performed in each elevator 2. Therefore, the occurrence of confinement due to the shaking of the earthquake can be more reliably avoided.

The area set in the management system 1 does not have to match the area set in the Earthquake Early Warning. Further, in the management system 1, a plurality of areas may have overlapping parts with each other. A part or all of the areas set in the management system 1 may include a plurality of areas set in the Earthquake Early Warning.

Further, any of the remote control devices 12 may not be provided in the elevator 2. The remote control device 12 not provided in the elevator 2 may be, for example, a device equipped with a function of receiving an Earthquake Early Warning located in an area where a plurality of elevators 2 are provided. The remote control device 12 not provided in the elevator 2 does not have to be located in the area as long as it can receive the Earthquake Early Warning delivered to the area.
