Description

This disclosure relates to an elevator central control device and an elevator management system.

Patent Document 1 discloses an example of an elevator management system. In the management system, the arrival time and maximum acceleration of seismic waves are predicted based on information from an emergency earthquake warning. In the elevator, an operation to stop the elevator at an evacuation floor is performed based on the predicted arrival time and maximum acceleration.

JP 2007-161378 A

However, in the management system of Patent Document 1, the arrival time and maximum acceleration of the seismic waves are predicted by calculations based on the location of the epicenter and the location of the building. Meanwhile, the impact of an earthquake on an elevator can vary depending not only on the location of the building in which the elevator is installed, but also on the structure of the building itself. If there is an error in predicting the impact of an earthquake on an elevator, there is a possibility of an erroneous determination being made as to whether or not evacuation, such as stopping the elevator at an evacuation floor, is necessary. When an erroneous determination is made as to whether or not evacuation is necessary, elevator users may become trapped in the car.

This disclosure is directed to solving such problems. This disclosure provides a central control device and a control system for elevators that can more reliably prevent people from becoming trapped due to earthquake shaking.

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

The management system 1 is a system that remotely manages multiple elevators 2. The remote management in the management system 1 includes responding to earthquakes in each elevator 2. The remote management in the management system 1 is performed based on earthquake alerts, such as emergency earthquake alerts.

The Earthquake Early Warning is an earthquake early warning that is distributed by a distribution agency 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 the earthquake that has occurred, as well as predicted values for the intensity of shaking caused by the earthquake for each pre-set area, and predicted values for the time of arrival of seismic waves to the area. The earthquake epicenter information 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, and the depth. The intensity of the epicenter is expressed, for example, by magnitude. Information on the intensity of the shaking is, for example, the seismic intensity scale. Information on the intensity of the shaking included in the Earthquake Early Warning may be, for example, maximum acceleration.

In the management system 1, multiple regions are set in advance. The multiple elevators 2 that are remotely managed by the management system 1 are provided in one of the regions set in the management system 1. The region set in the management system 1 is, for example, a region set in an emergency earthquake warning. In this example, region A, region B, etc. are set as the regions of the management system 1.

The elevator 2 remotely managed by the management system 1 is applied to a building 4 having, for example, multiple floors. A hoistway 5 for the elevator 2 is provided in the building 4. The hoistway 5 is a vertically long space that spans multiple floors. Each elevator 2 includes a hoist 6, a main rope 7, a car 8, a counterweight 9, an earthquake sensor 10, a control panel 11, and a remote management device 12.

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

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

The car 8 is a device that transports users of the elevator 2 between multiple floors by traveling vertically through the hoistway 5. The counterweight 9 is a device that balances the load on both sides of the sheave of the hoisting machine 6 between the car 8 and the counterweight 9. The car 8 and the counterweight 9 travel in opposite directions through the hoistway 5 by the driving force generated by the motor of the hoisting machine 6.

The earthquake sensor 10 is a device that detects earthquake waves such as P waves (primary wave) or S waves (secondary wave) of an earthquake. The earthquake sensor 10 is placed, for example, in a pit at the bottom of the elevator shaft 5. Alternatively, if a machine room is provided, the earthquake sensor 10 may be placed in the machine room. The earthquake sensor 10 is connected to the control panel 11 so that it can output a detection signal when it detects earthquake waves with an amplitude larger than a preset size, for example.

The control panel 11 is a device that controls the operation of the elevator 2 in which the control panel 11 is installed. The operation of the elevator 2 includes, for example, the running of the car 8. The control panel 11 is arranged, for example, at the upper or lower part of the hoistway 5. Alternatively, if a machine room is provided, the control panel 11 may be arranged in the machine room. The control panel 11 transitions to controlled operation, for example, when it receives a detection signal output from the earthquake sensor 10. The controlled operation may include, for example, a diagnostic operation that automatically diagnoses the effect of an earthquake on the elevator 2.

The remote management device 12 is a device that remotely manages the elevator 2 in which the remote management device 12 is installed. The remote management device 12 causes the elevator 2 to perform evacuation in response to the occurrence of an earthquake, and to switch to controlled operation, for example. The remote management device 12 is connected to the control panel 11 so that it can manage the operation of the elevator 2. The remote management device 12 is included in the management system 1.

The remote management device 12 of at least one of the elevators 2 is equipped with a function for receiving emergency earthquake alerts distributed from the distribution agency 3 to the area in which the elevator 2 is installed. When receiving an emergency earthquake alert, the remote management device 12 is equipped with a function for transferring the epicenter information contained in the emergency earthquake alert within the management system 1. At this time, the remote management device 12 may transfer the received emergency earthquake alert as is.

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

The history memory unit 14 is a part that accumulates and stores history information. The history information is information that associates epicenter information of earthquakes that have occurred in the past with arrival information of the seismic waves of the earthquakes at each elevator 2. The arrival information of the seismic waves includes information on whether or not the earthquake waves have been detected by the earthquake sensor 10 installed in the elevator 2, and information on the detection time when the earthquake sensor 10 detected the earthquake waves. Whether or not the earthquake sensor 10 has detected the earthquake waves corresponds, for example, to whether or not a detection signal has been output to the control panel 11. In this example, the history 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 according to an earthquake warning such as an emergency earthquake warning that has been distributed to the area where each elevator 2 is installed following the occurrence of the earthquake.

The input unit 15 is a part that accepts the transfer of epicenter information contained in an emergency earthquake alert from the remote management device 12 that has received the emergency earthquake alert. In this example, the input unit 15 is equipped with a function for collecting arrival information of the seismic waves of the earthquake from the remote management device 12 of each elevator 2, for example, after the earthquake has subsided. Here, the arrival information is stored as an operation log, for example, in the remote management device 12 or control panel 11 of each elevator 2. The arrival information collected by the input unit 15 is accumulated as history information in the history storage unit 14.

The distribution unit 16 distributes information such as operation commands for remote management to each elevator 2.

The analysis unit 17 is a part that analyzes whether or not each elevator 2 needs to respond to an earthquake based on the earthquake source information received by the input unit 15. The results of the analysis by the analysis unit 17 are distributed to each elevator 2 by the distribution unit 16. In this example, the results of the analysis by the analysis unit 17 are distributed to the remote management 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 seismic waves of a newly occurring earthquake at each elevator 2. The prediction unit 18 makes a prediction when the epicenter information of a newly occurring earthquake is input to the input unit 15. The prediction by the prediction unit 18 is made 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 learns in advance based on the history information. The learning performed by the prediction unit 18 is, for example, supervised learning using the history information as teacher data, with epicenter information as input and arrival information as output. The prediction unit 18 predicts, for example, the arrival or non-arrival of seismic waves detected by the earthquake sensor 10 as arrival information, and the arrival time of the seismic waves. The arrival time of the seismic waves is predicted as a relative time based on, for example, the occurrence time of the epicenter information.

The generation unit 19 is a part that generates an evacuation command for each elevator 2 based on the arrival prediction result by the prediction unit 18. The evacuation command is an operation command to make each elevator 2 perform evacuation processing. The generation unit 19 generates an evacuation command for an elevator 2 that the prediction unit 18 predicts will be reached by seismic waves detected by the earthquake sensor 10, for example. The generation unit 19 generates an evacuation command including a predicted value for the arrival time of the seismic waves. 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 evacuation commands are performed, for example, as follows. When a new earthquake occurs, the remote management device 12 of any elevator 2 in area A receives an emergency earthquake alert distributed to area A. At this time, the remote management device 12 transfers the earthquake's epicenter information to the input unit 15 of the central management device 13. The prediction unit 18 predicts the arrival of seismic waves of the earthquake for each elevator 2 installed in area A based on the results of learning performed in advance. The generation unit 19 generates an evacuation command for elevators 2 installed in area A for which the arrival of seismic waves detected by the earthquake sensor 10 is predicted based on the prediction result by the prediction unit 18. The distribution unit 16 distributes the evacuation command to elevators 2 installed in area A for which the evacuation command has been generated. In this example, the distribution unit 16 distributes the evacuation command immediately after the generation of the evacuation command. If the processing time required by the central management device 13 from inputting the epicenter information of a new earthquake to generating an evacuation command is sufficiently short, the distribution by the distribution unit 16 is performed before shaking caused by the earthquake occurs in area A. Upon receiving the evacuation command from the central management device 13, the remote management device 12 of the elevator 2 causes the control panel 11 to perform evacuation processing operations.

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 to determine whether or not evacuation is necessary for each elevator 2. The calculation unit 20 calculates the threshold value using, for example, a binary classification method. An example of a binary classification method is a method of classifying information on the predicted strength of shaking in an earthquake contained in historical information of earthquakes that have occurred in the past, based on whether or not seismic waves of the earthquake are detected by the earthquake sensor 10 installed in the elevator 2. The threshold value calculated by the calculation unit 20 is distributed to each elevator 2 by the distribution unit 16.

The calculation and distribution of the threshold is performed, for example, as follows. The calculation unit 20 starts calculating the threshold at, for example, a preset threshold calculation timing. The threshold calculation timing is, for example, once in a preset period. The distribution unit 16 distributes the threshold 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 is not receiving epicenter information. The remote management device 12 of the elevator 2 that has received the threshold from the central management device 13 determines whether or not evacuation processing is required based on the distributed threshold when receiving an emergency earthquake alert for a newly occurring earthquake. The remote management device 12 determines that evacuation processing is required, for example, when the predicted value of the shaking strength included in the emergency earthquake alert exceeds the previously distributed threshold. At this time, the remote management device 12 causes the control panel 11 to perform the evacuation processing operation.

Figure 2 is a flowchart showing an example of the operation of the central management device 13 in embodiment 1.

In step S20, the central management unit 13 determines whether the input unit 15 has received epicenter information of a new earthquake. If the determination result is Yes, the operation of the central management unit 13 proceeds to step S21. If the determination result is No, the operation of the central management unit 13 proceeds to step S24.

In step S21, the prediction unit 18 predicts the arrival of seismic waves from a newly occurring earthquake based on the epicenter information of the earthquake received by the input unit 15 and the history information stored in the history storage unit 14. After that, the operation of the central management unit 13 proceeds to step S22.

In step S22, the generation unit 19 generates an evacuation command based on the prediction result of the prediction unit 18. After that, the operation of the central management unit 13 proceeds to step S23.

In step S23, the distribution unit 16 distributes the evacuation command generated by the generation unit 19 to each elevator 2. After that, the operation of the central management device 13 proceeds to step S20.

In step S24, the calculation unit 20 determines whether it is now time to calculate the threshold value. If the determination result is Yes, the operation of the central management unit 13 proceeds to step S25. If the determination result is No, the operation of the central management unit 13 proceeds to step S20.

In step S25, the calculation unit 20 calculates the threshold value used to determine 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.

Figure 3 is a flowchart showing an example of the operation of the remote management device 12 according to embodiment 1.

In step S30, the remote management device 12 determines whether an 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. If 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 it has received an earthquake alert such as an emergency earthquake alert from the distribution agency 3. If the determination result is No, the operation of the remote management device 12 proceeds to step S30. If the determination result is Yes, the operation of the remote management device 12 proceeds to step S32. Note that a remote management device 12 that is not equipped with a function for receiving emergency earthquake alerts may skip the determination in step S31 and proceed to the operation of step S30, assuming that an emergency earthquake alert has not been received.

In step S32, the remote management device 12 transfers the epicenter information contained in the received emergency earthquake warning to the central management device 13. After that, the operation of the remote management device 12 proceeds to step S33.

In step S33, the remote management device 12 determines whether the predicted value of the shaking intensity contained in the received emergency earthquake warning is greater than the threshold value transmitted from the central management device 13. If the determination result is No, the operation of the remote management device 12 proceeds to step S30. If 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.
In FIG. 4, the operation of the control panel 11 for the evacuation operation is shown.

In step S40, the control panel 11 invalidates the registered hall 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 traveling. 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 direction of travel of the car 8. Here, the evacuation floor is a floor that has been preset from among a plurality of floors. If the determination result is Yes, the operation of the control panel 11 proceeds to step S43. If the determination result is No, the operation of the control panel 11 proceeds to step S45.

In step S43, the control panel 11 judges whether the traveling car 8 can stop at the evacuation floor by the predicted arrival time of the earthquake's seismic waves. Here, when the predicted value of the arrival time by the prediction unit 18 is distributed to the remote management device 12 together with an evacuation command or the like, the control panel 11 makes the judgment based on the predicted value by the prediction unit 18. Alternatively, when evacuation is performed not by an evacuation command but by an emergency earthquake warning or the like, the control panel 11 makes the judgment based on the predicted value of the arrival time included in the emergency earthquake warning. If the judgment result is Yes, the operation of the control panel 11 proceeds to step S44. If the judgment result is No, the operation of the control panel 11 proceeds to step S45.

In step S44, the control panel 11 stops the traveling car 8 at 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 traveling 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. A pause operation is an operation of the elevator 2 that continues for a preset pause time. During the pause operation, the car 8 is stopped at one of the floors. After that, the operation of the control panel 11 proceeds to step S47.

In step S47, the control panel 11 determines whether the earthquake detector 10 detected earthquake waves during 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 transitions to controlled operation. After that, the operation of the control panel 11 regarding the evacuation operation ends.

In step S49, the control panel 11 returns to normal operation. After that, the operation of the control panel 11 regarding the evacuation operation 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 that associates epicenter information of earthquakes that have occurred in the past with arrival information of seismic waves of the earthquakes in each elevator 2. The input unit 15 receives input of epicenter information of the earthquake from the remote management device 12 that has received an earthquake early warning such as an emergency earthquake warning when a new earthquake occurs. The earthquake early warning is distributed to an area where a plurality of elevators 2 are provided before shaking due to the earthquake occurs. The earthquake early warning includes epicenter information of the earthquake. The prediction unit 18 predicts the arrival of seismic waves of the earthquake in each elevator 2 when epicenter information of the newly occurring earthquake is input to the input unit 15. The prediction unit 18 makes a prediction 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 evacuation processing based on the arrival prediction result by the prediction unit 18. The distribution unit 16 distributes the evacuation command generated by the generation unit 19 for a newly occurring earthquake to each elevator 2 before shaking caused by the earthquake occurs in an area where multiple elevators 2 are installed. At least one of the multiple remote management devices 12 is provided in one of the elevators 2. When the remote management device 12 provided in one of the elevators 2 receives an evacuation command from the central management device 13, it causes the elevator 2 to evacuate.

With this configuration, the evacuation command is generated based on the prediction results using past arrival information. Because historical information about past earthquakes is used, a prediction is made that takes into account the influence of structures such as bedrock underground from the epicenter to the location where elevator 2 is installed. In addition, because predictions are not made by calculating the propagation of seismic waves, prediction results can be obtained quickly. As a result, evacuation commands based on the arrival prediction are delivered before the arrival of seismic waves. Because an evacuation command is delivered before shaking caused by a newly occurring earthquake occurs in elevator 2, evacuation of car 8 to an evacuation floor or the nearest floor, etc. can be more reliably performed. Therefore, entrapment due to earthquake shaking can be more reliably avoided.

The history storage unit 14 also 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 earthquake epicenter information. As information on the arrival of seismic waves of an earthquake at each elevator 2, the history storage unit 14 stores information on whether or not the seismic waves of the earthquake were detected by the earthquake sensor 10 installed in the elevator 2, and information on the detection time when the seismic waves of the earthquake were detected by the earthquake sensor 10.

This configuration allows predictions to be made that incorporate the effects of the structure of the building 4 to which the elevator 2 is applied. This allows for a more accurate determination of whether evacuation is necessary, making it possible to more reliably prevent people from becoming trapped due to earthquake shaking.

The central management device 13 also includes a calculation unit 20. The history storage unit 14 stores information on the predicted intensity of shaking in past earthquakes, including it in the history information of the earthquake. When an earthquake early warning distributed when a new earthquake occurs includes a predicted value of the intensity of shaking caused by the earthquake, the input unit 15 receives an input of the predicted value of the intensity of shaking caused by the earthquake from the remote management device 12 that received the earthquake early warning. The calculation unit 20 calculates a threshold value for the intensity of shaking caused by the earthquake for each elevator 2. The threshold value calculated here is used by each elevator 2 to determine whether or not evacuation is required when it 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 this configuration, the results of the analysis by the analysis unit 17 are delivered in advance to the remote management device 12 of each elevator 2 as a calculated threshold value. As a result, when an earthquake alert is received in each elevator 2, a response is made promptly based on the analysis results taking into account the historical information. In addition, because the analysis results are delivered before an earthquake occurs, even if a communication failure or the like occurs due to the earthquake, each elevator 2 will be able to respond based on the analysis results taking into account the historical information. This makes it possible to more reliably avoid people being trapped due to earthquake shaking.

The areas set in the management system 1 do not have to match the areas set in the Earthquake Early Warning. In addition, in the management system 1, multiple areas may overlap with each other. Some or all of the areas set in the management system 1 may include multiple areas set in the Earthquake Early Warning.

In addition, any of the remote management devices 12 does not have to be installed in the elevator 2. The remote management device 12 that is not installed in the elevator 2 may be, for example, a device equipped with a function for receiving emergency earthquake alerts that is located in an area where multiple elevators 2 are installed. The remote management device 12 that is not installed in the elevator 2 does not have to be located in the area as long as it can receive emergency earthquake alerts distributed to that area.

Next, an example of the hardware configuration of the management system 1 will be described with reference to FIG.
FIG. 5 is a hardware configuration diagram of a main part of the management system 1 according to the first embodiment.

Each function of the management system 1 can be realized by a processing circuit mounted on the central management device 13, the remote management device 12, etc. The processing circuit includes at least one processor 100a and at least one memory 100b. The processing circuit may include at least one dedicated hardware 200 in addition to the processor 100a and the memory 100b, or in place of them.

When the processing circuit includes a processor 100a and a memory 100b, each function of the management 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 100b. The processor 100a realizes each function of the management system 1 by reading and executing the program stored in the memory 100b.

The processor 100a is also called a CPU (Central Processing Unit), processing device, arithmetic device, microprocessor, microcomputer, or DSP. The memory 100b is composed of non-volatile or volatile semiconductor memory such as RAM, ROM, flash memory, EPROM, and EEPROM.

When the processing circuitry comprises dedicated hardware 200, the processing circuitry may be implemented, for example, as 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 management system 1 can be realized by a processing circuit. Alternatively, each function of the management system 1 can be realized collectively by a processing circuit. Some of the functions of the management system 1 may be realized by dedicated hardware 200, and other parts may be realized by software or firmware. In this way, the processing circuit realizes each function of the management system 1 by dedicated hardware 200, software, firmware, or a combination of these.
