Earthquake damage management system

Abstract

An earthquake damage management system comprises: a response information reception unit that receives response information from an elevator that responds to an occurring earthquake; an earthquake information reception unit that receives earthquake information of an earthquake that has occurred from an external service; a storage unit that stores a recovery management list that manages the post-earthquake response conditions in association with the post-earthquake response conditions; and a list management unit that, when the response information is accepted, registers the management information of the elevators on which the response information has been reported in the recovery management list, and, on the basis of the earthquake information, associates the corresponding earthquake with the management information and registers the associated earthquake in the recovery management list. When a previous earthquake and a current earthquake occur in order at intervals in the target area and the response information receiving unit receives response information after the current earthquake, the response information receiving unit receives response information. The list management unit calculates an index value for determining whether the reception of the response information by the response information reception unit after the last earthquake has ended when the present earthquake occurs, and determines an earthquake corresponding to the management information registered after the present earthquake on the basis of the index value.

[0005] Patent Document 1: Japanese Patent Application Publication No. 2007-126260 Summary of the invention

[0006] Problems to be solved by the invention

[0007] The timing of reporting the operation suspension information from the elevator device to the monitoring center is not limited to just after the earthquake occurs. That is, the timing of the report is sometimes delayed due to communication failures, the day of the week when the earthquake occurs, the time period, etc. Therefore, when the interval between the last earthquake and the current earthquake is short, it may not be possible to distinguish which earthquake caused the damage. In this case, it is impossible to distinguish and manage the recovery management list for the elevators to be restored according to each earthquake, and there is a problem that it is difficult to manage the elevators that are the objects of restoration. In addition, information on the damage status of the elevator is reported from each maintenance company to the administrative agency. The reported information is used in the administrative agency for earthquake-resistant measures for elevators and research on guidelines for maintenance / installation companies. Therefore, it is of great significance to grasp the damage status according to each earthquake.

[0008] The present disclosure has been made to solve the above-mentioned problems, and an object of the present disclosure is to provide a technology of an earthquake damage management system that is useful for managing damage and recovery from multiple earthquakes.

[0009] Means for solving problems

[0010] The earthquake damage management system disclosed in the present invention comprises: a response information receiving unit that receives response information from an elevator that has responded to an earthquake occurring in a target area where a plurality of elevators are installed; an earthquake information receiving unit that receives earthquake information of an earthquake occurring in the target area from an external service; a storage unit that stores a recovery management list that manages the response status after an earthquake for a plurality of elevators in a corresponding manner; and a list management unit that, when the response information receiving unit receives the response information, registers the management information of the elevator that has reported the response information in the recovery management list, and registers the corresponding earthquake in the recovery management list in correspondence with the management information based on the earthquake information. The list management unit is configured to calculate an index value for determining whether the acceptance of the response information by the response information receiving unit after the previous earthquake has been completed when the current earthquake occurs, and determine the earthquake corresponding to the management information registered after the current earthquake based on the index value, when the previous earthquake and the current earthquake occur in sequence at intervals in the target area and the response information receiving unit receives the response information after the current earthquake.

[0011] Effects of the Invention

[0012] According to the earthquake damage management system disclosed in the present invention, when the last earthquake and the current earthquake occur in sequence at intervals and response information is accepted after the current earthquake, the earthquake corresponding to the management information of the elevator that reported the response information is determined based on whether the acceptance of the response information by the response information accepting unit after the last earthquake has been completed when the current earthquake occurs. According to such an operation, the management information of the elevator can be registered in correspondence with the earthquake. Thus, a technology of an earthquake damage management system that is conducive to managing damage and recovery for multiple earthquakes using a recovery management list can be provided.

[0034] Implementation

[0035] 1. Structure of earthquake damage management system for elevators

[0036] Figure 1 1 is a diagram showing the configuration of an earthquake damage management system according to the present embodiment. The elevator to which the earthquake damage management system 100 according to the present embodiment is applied is an elevator 2. The elevator may include, for example, an escalator or a moving walkway.

[0037] The elevator system 1 is a system including a plurality of elevators 2. Each elevator 2 is applied to a building having a plurality of floors, for example. A plurality of elevators 2 may be installed in one building. A shaft 3 for the elevators 2 is installed in the building. The shaft 3 is a long space in the vertical direction that extends over a plurality of floors. In this example, each elevator 2 is a traction elevator. In addition, the elevator system 1 may include a drum elevator and a hydraulic elevator, for example. The traction elevator has a traction machine 4, a main rope 5, a car 6, a counterweight 7, an earthquake sensor 8, and a control panel 9.

[0038] The traction machine 4 has a motor that generates a driving force and a sheave that rotates by the driving force generated by the motor. The traction machine 4 is, for example, arranged at the upper part or the lower part of the hoistway 3. Alternatively, when a machine room is provided in the elevator 2, for example, above the hoistway 3, the traction machine 4 may also be arranged in the machine room.

[0039] The main rope 5 is a rope that supports the load of the car 6 and the counterweight 7 in the hoistway 3. The main rope 5 is wound around the sheave of the hoisting machine 4. The main rope 5 supports the load of the car 6 on one side of the sheave of the hoisting machine 4. The main rope 5 supports the load of the counterweight 7 on the other side of the sheave of the hoisting machine 4. The main rope 5 moves in a manner that pulls up one side of the sheave of the hoisting machine 4 by the driving force generated by the motor of the hoisting machine 4.

[0040] The car 6 is a device that transports passengers of the elevator 2 between multiple floors by running in the vertical direction in the hoistway 3. The counterweight 7 is a device that balances the load of the car 6 applied to one side of the sheave of the traction machine 4 on the other side of the sheave of the traction machine 4. As the main rope 5 is moved by the motor of the traction machine 4, the car 6 and the counterweight 7 run in the hoistway 3 in the vertical direction to the opposite sides.

[0041] The earthquake sensor 8 is a device that senses earthquake waves at a location where the elevator 2 is installed. The earthquake sensor 8 is disposed, for example, in the hoistway 3 or the like. Alternatively, when a machine room is installed, the earthquake sensor 8 may be disposed in the machine room.

[0042] The control panel 9 is a device for controlling the movement of the elevator 2. The movement of the elevator 2 includes, for example, the travel of the car 6. The control panel 9 is, for example, arranged at the upper part or the lower part of the shaft 3. Alternatively, when a machine room is provided, the control panel 9 may also be arranged in the machine room. The control panel 9 is connected to the equipment of the elevator 2 so as to obtain the state information of the elevator 2 for controlling the movement of the elevator 2. The control panel 9 obtains the state information of the elevator 2 from, for example, sensors or switches provided in the car 6, the traction machine 4 or the shaft 3 of the elevator 2. The control panel 9 obtains the sensing information of the seismic wave from the seismic sensor 8.

[0043] The control panel 9 responds to the earthquake based on the sensing information of the earthquake wave obtained from the earthquake sensor 8. The response to the earthquake includes, for example, a controlled operation or a stopped operation. The controlled operation is an automatic operation in response to the earthquake that has occurred. The controlled operation includes a diagnostic operation for diagnosing the effect of the earthquake on the elevator 2. The stopped operation is a response in which the car 6 is stopped and waited without running.

[0044] Each elevator 2 includes a remote monitoring device 11. The remote monitoring device 11 is a device that monitors the state of the elevator 2. The remote monitoring device 11 acquires state information of the elevator 2 from, for example, the control panel 9 or the like.

[0045] An earthquake damage management system 100 is applied to the elevator system 1. The earthquake damage management system 100 is a system for managing earthquake damage to a plurality of elevators 2 in the elevator system 1. The earthquake damage management system 100 includes a central management device 13 and a response management device 15.

[0046] The central management device 13 is a device for remotely monitoring each elevator 2. The central management device 13 is, for example, arranged in an information center 16 or the like. The information center 16 is a base for collecting information of a plurality of elevators 2. The central management device 13 is, for example, one or more server devices or the like. The central management device 13 is connected to each remote monitoring device 11, for example, through an intranet of a maintenance company using the earthquake damage management system 100, so that communication of the status of each elevator 2 during normal operation, etc., can be performed.

[0047] The response management device 15 is a device for managing the response status after the earthquake for each elevator 2 installed in the area where the earthquake motion based on the earthquake occurred. The response management device 15 is configured in the information center 16, for example. The response management device 15 is one or more server devices, for example. The central management device 13 is connected to each remote monitoring device 11, for example, through the internal network of the maintenance company, so that the response information of each elevator 2 to the earthquake can be communicated. The response management device 15 is connected to the central management device 13, for example, through the internal network of the maintenance company, so that the information of the response status managed can be shared. The response management device 15 is connected to a communication network such as the Internet or a telephone line network, for example, so that information from an external service 19 can be received. The external service 19 is, for example, a service outside the earthquake damage management system 100 that publishes earthquake information. The external service 19 is provided by, for example, a public institution or a private institution such as the Meteorological Agency of Japan or a similar institution in other countries.

[0048] The response management device 15 includes an earthquake information receiving unit 20 , a response information receiving unit 21 , a storage unit 22 , a process information receiving unit 23 , a list management unit 24 , a statistics unit 25 , a photograph data receiving unit 26 , and a bird's-eye view display unit 27 .

[0049] The earthquake information receiving unit 20 is a part that receives earthquake information from the external service 19. The earthquake information receiving unit 20 receives earthquake information related to the target area where at least one of the multiple elevators 2 is installed from the external service 19. When an earthquake occurs, the earthquake information is released from the external service 19. The earthquake information includes, for example, information such as the area where the earthquake occurred, the time when the earthquake occurred, and the size of the earthquake that occurred. The size of the earthquake includes, for example, information on the magnitude level. The earthquake information may also include information on the earthquake that caused the earthquake. The earthquake information includes information such as the time when the earthquake occurred, the epicenter of the earthquake, and the size of the earthquake. The size of the earthquake includes, for example, information on the magnitude. The received earthquake information is recorded in the storage unit 22.

[0050] The response information receiving unit 21 is a part that receives information related to the response of the elevator 2 to the earthquake from each remote monitoring device 11. This information is hereinafter referred to as "response information". The response information includes the response content such as the controlled operation or operation stop of the elevator 2 and the identification information for specifying the elevator 2. The identification information for specifying the elevator 2 is, for example, information such as the building number of the building where the elevator 2 is installed and the elevator number of the elevator 2 uniquely set in the building.

[0051] The storage unit 22 is a part for storing a restoration management list, a damage management list, and a history list. The restoration management list is a list of management information for post-earthquake response management related to each elevator 2 installed in the target area where the earthquake occurred. The damage management list is a list for extracting and managing the management information of the elevator 2 that has been damaged from the restoration management list. The history list is a list for accumulating and managing the management information of the elevator 2 that has been restored.

[0052] The passing information receiving unit 23 is a unit that receives passing information indicating the response status of the elevator 2. The passing information includes operations performed by the maintenance worker through the maintenance terminal 18. The operations received by the passing information receiving unit 23 include, for example, input operations of information related to the status of the response status after the earthquake. The response status includes, for example, the recovery of the elevator 2, whether it is not recovered, recovery in progress, recovery completed, whether there is damage, and the status of damage.

[0053] The list management unit 24 is a part that manages the restoration management list, the property damage management list, and the experience list. The list management unit 24 registers the management information of the elevators that need to be managed after the earthquake among the plurality of elevators 2 in the restoration management list. The list management unit 24 registers the earthquake information and the management information in the restoration management list in correspondence. In addition, the list management unit 24 registers the experience information after the earthquake in correspondence with the management information in the management object list.

[0054] The list management unit 24 moves the management information of the elevator that has been damaged from the management information registered in the restoration management list to the damage management list. In addition, the list management unit 24 moves the management information of the elevator that has been restored from the management information registered in the restoration management list or the damage management list to the experience list at a predetermined timing.

[0055] The statistics unit 25 is a part that performs statistics on the management information registered in the recovery management list. The statistics unit 25 performs statistics on the management information for each earthquake, for example. The statistics unit 25 performs statistics on the number of elevators registered in the recovery management list and the number of elevators for which post-earthquake response has been completed for each earthquake, for example. In addition, the statistics unit 25 performs statistics on the number of trapped cases that occurred in the elevators registered in the recovery management list and the number of trapped cases for which rescue has been completed for each earthquake, for example.

[0056] The photo data receiving unit 26 is a part that receives the photo data of the restoration site transmitted from the maintenance terminal 18. The photo data includes a photo of the restoration site taken by the maintenance worker and information for specifying the location of the restoration site.

[0057] The bird's-eye view display unit 27 is a unit for displaying various information of the management information registered in the recovery management list, the item list, and the experience list on a map. The processing performed in the bird's-eye view display unit 27 is hereinafter referred to as "bird's-eye view display processing". Examples of the information displayed in the bird's-eye view display processing include recovery rate, passage information, photo data, etc.

[0058] 2. Operation Example of Earthquake Damage Management System 100

[0059] Next, an example of operations executed in the earthquake damage management system 100 will be described.

[0060] 2-1. Basic movements

[0061] Taking the case where an earthquake A occurs in a target area where the elevator 2 is installed as an example, the basic operation executed in the response management device 15 of the earthquake damage management system 100 will be described. Figure 2 Schematically showing the contents of the response screen at each time of the recovery management list after an earthquake occurs. Figure 2 In the timeline shown, "end of occurrence" indicates the period when the acceptance of damage caused by earthquake A based on response information tends to a specified level, "start of recovery" indicates the period when maintenance personnel start recovery work, "end of recovery" indicates the period when all damage caused by earthquake A except property damage is fully recovered, and "full recovery completed" indicates the period when all damage caused by earthquake A including property damage is fully recovered.

[0062] When earthquake A occurs, the response information receiving unit 21 receives the response information of the elevator 2 to the earthquake from each remote monitoring device 11. Normally, the number of response information received at each time point increases sharply immediately after earthquake A occurs, but then tends to zero as time passes. The list management unit 24 receives the response information and registers the management information including the response information of the elevator 2 that requires post-earthquake response management in the recovery management list. This process is hereinafter referred to as the "recovery list registration process." In the recovery list registration process, the list management unit 24 registers the process information in correspondence with each piece of management information. Figure 2 In the example of FIG. 1 , the elevators 2 of the AA building, the BB building, the CC building, and the DD building are schematically shown, and the response content of each is that the operation is stopped and the maintenance personnel have not yet responded.

[0063] Furthermore, in the restoration list registration process, the list management unit 24 registers the information of the earthquake directly related to the response in correspondence with the registered management information. Figure 2 In the example of , "Earthquake A" is registered in correspondence with the elevators 2 of the AA building, the BB building, the CC building, and the DD building.

[0064] The statistics section 25 collects statistics on different branches / offices, the number of stopped / restored items, the number of damaged items, and other information in the recovery management list according to the earthquake, and displays them on the response screen. This process is hereinafter referred to as "list statistics processing". The maintenance manager activates the recovery system with reference to the response screen. Each maintenance worker confirms the progress of the recovery through the response screen while performing the confirmation and recovery operations of the damage status. At this time, each maintenance worker appropriately inputs the process information including the response status after the earthquake through the maintenance terminal 18. The list management section 24 updates the management information at any time based on the process information accepted by the process information acceptance section 23.

[0065] In the restoration management for earthquake A, when the restoration of all elevators including property damage has been completed, the list management unit 24 moves all management information registered in the restoration management list corresponding to earthquake A to the experience list. This process is hereinafter referred to as "experience list movement process". As a result, the response screen of the restoration management list for earthquake A becomes empty.

[0066] 2-2. Characteristic Operations in Restoration List Registration Process

[0067] In the above-mentioned basic actions, in the recovery list registration process, when multiple earthquakes occur in a short period of time in the target area where the elevator 2 is installed, an adverse situation may occur. That is, the timing of the response information acceptance unit 21 accepting the response information is not limited to just after the earthquake occurs. That is, the acceptance of the response information may be delayed due to, for example, communication delays caused by the earthquake. In addition, the following situation should be considered: in the case where the building manager contacts the damage by phone, it is impossible to contact quickly after the earthquake. In this way, it can be considered that the number of acceptances of response information at each time after the earthquake occurs increases sharply just after the earthquake occurs, but a certain degree of period is required until the occurrence ends thereafter. On the other hand, it is required to associate the earthquake name directly related to the damage with the response information. However, when multiple earthquakes occur at short intervals, it may be impossible to determine whether the response information accepted after this earthquake corresponds to the previous earthquake or the current earthquake.

[0068] In the earthquake damage management system 100 of the present embodiment, in the recovery list registration process, when the last earthquake and the current earthquake occur sequentially with intervals between them, the earthquake corresponding to the response information received after the current earthquake is determined based on whether the current earthquake occurs before or after the end of the last earthquake.

[0069] Figure 3 and Figure 4The diagrams are used to explain how the earthquake damage management system associates earthquakes with response information. In the examples shown in these diagrams, earthquake A occurred as the last earthquake, and earthquake B occurred as the current earthquake. Figure 3 In the example shown, an example is given in which earthquake B occurs before earthquake A is finished. Figure 4 In the example shown, a case where earthquake B occurs after earthquake A ends is illustrated.

[0070] When earthquake B occurs before earthquake A is over, list management unit 24 associates earthquake A with response information received after earthquake B. On the other hand, when earthquake B occurs after earthquake A is over, list management unit 24 associates earthquake B with response information received after earthquake B.

[0071] For example, it is possible to calculate an index value for judging the end of occurrence, and to judge the end of occurrence by comparing the index value with a threshold value. The index value is, for example, an incidence rate represented by the number of acceptances of response information per unit time. When the incidence rate is less than the threshold value, the list management unit 24 judges that the occurrence has ended. In addition, it can be considered that the incidence rate tends to change according to the day of the week or time period when the earthquake occurs. That is, there are also buildings that do not work on weekends or at night, and sometimes accept response information after the weekend or after the night. That is, there is a tendency for the period from weekends or nights to the end of occurrence to be prolonged compared to working days or daytime. In addition, in the case where a communication line fails after an earthquake, the acceptance of response information is sometimes delayed. In this case, the period until the end of occurrence may also be prolonged. Therefore, the threshold value of the incidence rate can also change according to the day of the week when the earthquake occurs, the time period, and whether there is a communication failure.

[0072] According to the above operation, even when a plurality of earthquakes occur consecutively, it is possible to associate the earthquake name with the response information. Next, a specific process of associating the earthquake name with the response information by the response management device 15 will be described.

[0073] Figure 5 This is a flowchart showing a routine for recording processing of earthquake information executed in the response management device 15. In step S10, the earthquake information receiving unit 20 determines whether an earthquake with a magnitude of 4 or more has occurred based on the earthquake information received from the external service 19. Based on past performance, it can be considered that when the magnitude of the earthquake is 3 or less, most elevators do not stop operating. Therefore, if the determination is not recognized, the information of the earthquake is not recorded for the purpose of reducing the system load, and this routine ends.

[0074] On the other hand, in the case where the determination of step S10 is recognized as established, the processing enters step S12. In step S12, the earthquake information of the earthquake with a magnitude of 4 or more recognized as occurring in step S10 is recorded after generation management. Here, the earthquake information receiving unit 20 compares the degree of consistency between the region of the new earthquake with a magnitude of 4 or more recognized as occurring in step S10 and the region of the recorded current earthquake. Then, when the consistency rate is below a specified value (for example, 30%), it is judged to be an earthquake different from the recorded current earthquake, and the current earthquake is set as the previous earthquake, and the previous earthquake is set as the previous earthquake, and then the new earthquake is recorded as the current earthquake in the storage unit 22. On the other hand, when the consistency rate is greater than a specified value, it is judged to be the same earthquake as the recorded current earthquake, and the newly recorded new earthquake is recorded as part of the current earthquake in the storage unit 22.

[0075] Figure 6 1 is a flowchart showing a routine for the restoration list registration process executed in the management device 15. Figure 6 In step S100 of the routine shown, it is determined whether the response information receiving unit 21 has received the response information. If the result is that the rejection determination is established, the routine ends, and if the approval determination is established, the process proceeds to step S102.

[0076] In step S102, the management information of the elevator 2 corresponding to the response information is registered in the recovery management list. In step S104, it is determined whether the occurrence of the previous earthquake has ended when the current earthquake occurs. Here, the list management unit 24 calculates the occurrence rate of the previous earthquake when the current earthquake occurs, and determines whether the calculated occurrence rate is less than a threshold value. If the result is that the determination of not approving is established, the process proceeds to step S106, and if the determination of approving is established, the process proceeds to step S108.

[0077] In step S106, the list management unit 24 registers the information of the last earthquake in correspondence with the management information of the elevator 2 that is the object. In step S108, it is determined whether the occurrence of this earthquake has ended. Here, the list management unit 24 calculates the incidence rate after the occurrence of this earthquake, and determines whether the calculated incidence rate is less than a threshold value. The threshold here is a threshold value predetermined in order to determine whether the occurrence of this earthquake has ended, for example, the number of occurrences per unit time (for example, n occurrences / m minutes) is used. If the result is that the determination is approved, it is determined that the occurrence of this earthquake has ended, and the processing enters step S110. If the determination is not approved, it is determined that the occurrence of this earthquake has not ended, and the processing enters step S112.

[0078] In step S110, it is determined that there is a possibility of misjudgment in the automatic judgment of the system, and the earthquake name corresponding to the management information is set to "unknown", and the earthquake corresponding to the management information is determined by human judgment. In step S112, the list management unit 24 registers the current earthquake in correspondence with the management information of the elevator 2 that is the target.

[0079] According to the above processing, for the reception of response information after the current earthquake, it can be determined whether it corresponds to the previous earthquake, the current earthquake, or "unknown". Therefore, even when earthquakes occur continuously one after another, the earthquake names can be associated with the management information.

[0080] 2-3. Characteristic actions in the experience list movement process

[0081] In the above-mentioned basic operation, in the experience list transfer process, in the management information of the elevator corresponding to the earthquake A in the restoration management list, when all restoration including property damage has been completed, all of this management information is moved to the experience list. However, in this operation, when the restoration of property damage takes a long time, the restored elevators are not moved to the restoration management list and remain for a long time, making it difficult to view the response screen of the restoration management list, and there is a problem of misidentifying the damage status.

[0082] Therefore, in the earthquake damage management system 100 of the present embodiment, the management information of the elevators corresponding to the property damage among the management information of the elevators registered in the restoration management list is moved to the property damage management list. This process is hereinafter referred to as "property damage management list movement process". Thus, the management information of the elevators registered in the restoration management list can be moved to the experience list without waiting for the restoration of the damaged elevators. Thus, the visual recognizability of the response screen is improved, and thus the convenience of use for the maintenance personnel is improved.

[0083] In addition, for the elevator moved to the damage management list by the damage management list transfer process, the management information is updated at any time according to the passing information. Then, the management information of the elevator that has been restored is moved from the damage management list to the experience list.

[0084] Figure 7 1 is a flowchart showing a routine of the experience list transfer process executed in the response management device 15. Figure 7 Here, the processing performed on the restoration management list related to Earthquake A is exemplified.

[0085] exist Figure 7In step S200 of the routine shown, the list management unit 24 updates the management information registered in the restoration management list of earthquake A based on the passage information received by the passage information receiving unit 23. In step S202, the list management unit 24 determines whether the management information of the damaged elevator is registered in the restoration management list. If the result is that the rejection determination is established, the process proceeds to step S206, and if the approval determination is established, the process proceeds to step S204.

[0086] In step S204, the list management unit 24 moves the management information of the damaged elevator from the restoration management list to the damage management list. After the processing of step S204 is completed, the processing proceeds to step S206. In step S206, the list management unit 24 determines whether the restoration of all elevators registered in the restoration management list of earthquake A has been completed. If the result is that the approval judgment is established, the processing proceeds to step S208, and if the approval judgment is not established, this routine ends. In step S208, the list management unit 24 moves all the management information of the elevators whose restoration has been completed to the experience list. After the processing of step S208 is completed, this routine ends.

[0087] 2-4. First specific example of experience list movement processing

[0088] Next, a first specific example of the history list movement process will be described. Figure 8 1 is a diagram illustrating a portion of a recovery management list when an earthquake A occurs. In addition, there are multiple items in the recovery management list shown below in addition to the items shown in the diagram, but they are omitted here. In the example shown in the figure, at time 10:00, an earthquake A with a magnitude of 4 occurs in the target area XX. Receiving the earthquake A, the list management unit 24 registers the content of the response information received by the response information receiving unit 21 as management information in the recovery management list. Figure 8 The restoration management list shown is counted for each corresponding earthquake. When earthquake A occurs, the restoration management list of earthquake A, which is the latest earthquake, is displayed on the response screen by default. The restoration management list with the earthquake name "None" is a list in which the management information of elevators that need to be restored due to earthquakes with a magnitude of 3 or less or reasons other than earthquakes is registered.

[0089] Fig. 9 This is a diagram illustrating a portion of the restoration management list at the start of restoration. In the example shown in this figure, restoration starts at 10:30. The maintenance personnel confirm the damage status at each site and appropriately input the process information including the response status after the earthquake through the maintenance terminal 18. The list management unit 24 updates the management information at any time based on the process information received by the process information receiving unit 23. Fig. 9In the example shown, property damage is registered in the management information of the EE building. Therefore, the list management unit 24 moves the management information of the EE building corresponding to the property damage to the property damage management list. Fig.10 2 is a diagram illustrating an example of a damage management list. As shown in the diagram, the management information of the machine No. 001 of the EE building registered in the restoration management list is moved to the damage management list.

[0090] Fig.11 1 is a diagram illustrating a portion of the recovery management list when recovery is completed. In the example shown in the figure, it is illustrated that all recovery related to earthquake A is completed at 12:00 the next day. In this case, the list management unit 24 moves all management information of the recovery management list related to earthquake A to the experience list. Fig.12 2 is a diagram illustrating a part of the history list. As shown in the diagram, information of restored elevators is accumulated and managed in the history list.

[0091] Fig.13 2 is a diagram illustrating a damage management list. When an elevator registered in the damage management list has been restored, the list management unit 24 moves the management information of the restored elevator to the history list.

[0092] According to the above operation, the management information of the damaged elevator that may take a long time to be restored can be managed by the damaged management list different from the restoration management list. Thus, it is possible to prevent the damaged elevator from being retained in the restoration management list for a long period of time.

[0093] 2-5. Second specific example of experience list movement processing

[0094] Next, a second specific example of the history list movement process will be described. Fig.14 FIG. 1 is a diagram illustrating a portion of a restoration management list when an earthquake B occurs. In the example shown in the diagram, Fig.10 At 11:00 after the restoration of the earthquake A shown in the figure started, an earthquake B of magnitude 6 occurred in the target area XX. Receiving the earthquake B, the list management unit 24 registers management information including the response information accepted by the response information acceptance unit 21 in the restoration management list. Fig.14 The restoration management list shown is counted for each corresponding earthquake. When earthquake B occurs, the restoration management list of earthquake B, which is the latest earthquake, is displayed on the response screen by default. Fig.14 In the example of the recovery management list shown in FIG, the elevator of the AA building that was restored after stopping due to the earthquake A stops operating again due to the earthquake B. Fig.14 In the example of the restoration management list shown, the elevators of the CC building, the DD building, and the FF building that were not stopped in the earthquake A are stopped due to the earthquake B.

[0095] Fig.15 This is a diagram illustrating a portion of the recovery management list at the end of recovery. In the example shown in this figure, it is illustrated that all recovery related to earthquake B has been completed at 13:00 the next day. In addition, the recovery management list related to earthquake A was completed at 12:00, so the recovery management list related to earthquake A has been deleted.

[0096] The list management unit 24 moves all elevators in the restoration management list related to the earthquake B to the experience list. Fig.16 2 is a diagram illustrating a part of the history list. As shown in the diagram, the management information of the restored elevator is managed using the history list.

[0097] The history list is used, for example, when making a post-damage report for each earthquake. The statistical unit 25 compiles statistics on the management information of the stopped elevators for each earthquake. The statistical results are used, for example, in a report for an application to an administrative office.

[0098] 2-6. Characteristic Operations of Bird's-Eye Display Processing

[0099] In the bird's-eye view display process, the bird's-eye view display unit 27 displays a part of the management information of the restoration management list in a bird's-eye view manner on a map, for example. Fig.17 This is a diagram showing an example of the contents of the restoration management list displayed in a bird's-eye view on a map. In the example shown in the figure, icons are displayed and selected in the map including the target area. The icons displayed here illustrate, for example, restored elevators, damaged elevators, and offices. The icons of offices visually represent the restoration rate of elevators under their jurisdiction and the attendance rate of buildings under their jurisdiction. The maintenance personnel confirm the damage status and response status of the target area while referring to these bird's-eye views.

[0100] In addition, the icons that can be displayed on the map are not limited to Fig.17 That is, the statistics unit 25 can also display and select icons of information counted in the recovery management list such as trapped, power outage, flood, etc. in a wide range.

[0101] When the icon of an office is clicked, the bird's-eye view display unit 27 displays a detailed display screen compiled for each office. Fig.18 1 is a diagram showing an example of a detailed display screen for each office. In the example shown in the figure, the automatic counting results of the elevator and the automatic counting results of the personnel are displayed. The maintenance personnel can confirm the detailed response status by referring to the detailed display screen.

[0102] In addition, the photo data of the restoration site can also be associated with the icon on the map. For example, the maintenance worker takes a photo of the restoration site of the damaged elevator, adds location information to the photo data, and sends it from the maintenance terminal 18 to the information center 16. The photo data receiving unit 26 receives the photo data of the restoration site sent from the maintenance terminal 18. The received photo is associated with the icon of the corresponding elevator location. After clicking the icon, the overhead display unit 27 displays the corresponding photo. According to such processing, the maintenance worker can easily confirm the photo of the restoration site from the display screen.

[0103] 4. Modifications

[0104] The earthquake damage management system 100 of the present embodiment may be applied in the following modified forms.

[0105] 4-1. Hardware resources of the earthquake damage management system 100

[0106] Fig.19 1 is a diagram showing an example of hardware resources of the earthquake damage management system 100. As hardware resources, the response management device 15 of the earthquake damage management system 100 has a processing circuit 34 including a processor 30 and a memory 32. The processing circuit 34 may include a plurality of processors 30. The processing circuit 34 may also include a plurality of memories 32.

[0107] In this embodiment, the components shown by reference numerals 20 to 27 represent functions of the response management device 15. The functions of the storage unit 22 are implemented by the memory 32. The functions of the components shown by reference numerals 20 to 27 can be implemented by software, firmware, or a combination of software and firmware described as a program. The program is stored in the memory 32. The response management device 15 executes the program stored in the memory 32 through the processor 30 (computer), thereby implementing the functions of the components shown by reference numerals 20 to 27.

[0108] The processor 30 is also called a CPU (Central Processing Unit), a central processing device, a processing device, an arithmetic device, a microprocessor, a microcomputer or a DSP. As the memory 32, a semiconductor memory, a magnetic disk, a floppy disk, an optical disk, a high-density disk, a mini disk or a DVD may also be used. The semiconductor memory that can be used includes a RAM, a ROM, a flash memory, an EPROM and an EEPROM.

[0109] Fig. 20 FIG. 2 is a diagram showing another example of hardware resources of the earthquake damage management system 100. Fig. 20 In the example shown, the response management device 15 has a processing circuit 34 including a processor 30 , a memory 32 , and dedicated hardware 36 . Fig. 20The example in which a part of the functions of the management device 15 is implemented by the dedicated hardware 36 is shown. All the functions of the management device 15 may be implemented by the dedicated hardware 36. As the dedicated hardware 36, a single circuit, a complex circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof can be used.

[0110] In an area where the magnitude of earthquake B, which is the current earthquake, is greater than the magnitude of earthquake A, which is the previous earthquake, it can be considered that the elevators that stopped operating in earthquake A also stopped operating when earthquake B occurred. Therefore, when earthquake B occurs, the list management unit 24 may further associate earthquake B with the elevators that have stopped operating due to earthquake A. According to such processing, when performing a subsequent damage report, it is also possible to count only the damage scale of earthquake B.

[0111] The central management device 13 is not essential in the earthquake damage management system 100. When the earthquake damage management system 100 does not have the central management device 13, the response management device 15 of the information center 16 is connected to each remote monitoring device 11 via the intranet of the maintenance company, for example.
