Earthquake Damage Management System

Abstract

This earthquake damage management system comprises: a response information reception unit that receives response information from a raising / lowering device that has responded to an earthquake that has occurred; an earthquake information reception unit that receives earthquake information about the earthquake that has occurred from an external service; a storage unit that stores a recovery management list in which post-earthquake response conditions are associated and managed; and a list management unit that, when response information is received, registers management information for the raising / lowering device that has reported the response information in the recovery management list and, on the basis of the earthquake information, registers the corresponding earthquake in the recovery management list in association with the management information. When a previous earthquake and a current earthquake occur sequentially with an interval therebetween in an area and the response information reception unit receives response information after the current earthquake, 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 previous earthquake has ended at the time of occurrence of the current earthquake, and determines an earthquake to be associated with management information to be registered after the current earthquake on the basis of the index value.

Description

[Technical field]

[0001] The present disclosure relates to an elevator earthquake damage management system. [Background technology]

[0002] Patent Document 1 discloses technology relating to an earthquake recovery support device for elevator equipment. The earthquake recovery support device of this technology includes an earthquake sensor. The earthquake sensor outputs an earthquake detection signal when shaking caused by an earthquake exceeds a certain value. Upon receiving the earthquake detection signal, the control panel suspends the operation of the car and transmits information about the suspension of car operation and information about the scale of the earthquake to a monitoring center. The monitoring center automatically calculates the scheduled time for a technician to make a recovery visit from the received information. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2007-126260 Summary of the Invention [Problem to be solved by the invention]

[0004] The timing when the elevator equipment issues the suspension information to the monitoring center is not necessarily immediately after the occurrence of an earthquake. In other words, the timing of the report may be delayed depending on communication failure, the day of the week when the earthquake occurs, the time of day, etc. For this reason, if the interval between the previous earthquake and the current earthquake is short, it may be impossible to distinguish which earthquake caused the damage. In this case, there is a problem that the recovery management list that manages the elevators to be restored cannot be managed separately for each earthquake, making it difficult to manage the elevators to be restored. Information on the damage status of the elevators is reported by each maintenance company to the government agency. The reported information is used by the government agency to consider earthquake-proofing measures for elevators and guidelines for maintenance and installation companies. Therefore, it is important to understand the damage status for each earthquake.

[0005] The present disclosure has been made to solve the above-mentioned problems, and aims to provide technology for an earthquake damage management system that is advantageous in managing damage and recovery from multiple earthquakes. [Means for solving the problem]

[0006] The earthquake damage management system disclosed herein includes a response information receiving unit that receives response information from elevators that have responded to an earthquake that has occurred in a target area where multiple elevators are installed, an earthquake information receiving unit that receives earthquake information of an earthquake that has occurred in the target area from an external service, a storage unit that stores a recovery management list that associates and manages post-earthquake response situations for multiple elevators, and a list management unit that, when the response information receiving unit receives the response information, registers management information of the elevator for which the response information has been issued in the recovery management list and registers the corresponding earthquake in the recovery management list in association with the management information based on the earthquake information. When a previous earthquake and a current earthquake occur in the target area in sequence with an interval therebetween and the response information receiving unit receives the response information after the current earthquake, the list management unit is configured to calculate an index value for determining whether the reception of response information by the response information receiving unit after the previous earthquake has converged at the time of the occurrence of the current earthquake, and to determine the earthquake to be associated with the management information to be registered after the current earthquake based on the index value. Effect of the Invention

[0007] According to the earthquake damage management system disclosed herein, the previous earthquake and the current earthquake occur in sequence with an interval between them, and when response information is received after the current earthquake, the earthquake to be associated with the management information of the elevator for which the response information was issued is determined depending on whether the reception of response information by the response information receiving unit after the previous earthquake has converged at the time of the occurrence of the current earthquake. According to this operation, the elevator management information and the earthquake can be registered in association with each other. This makes it possible to provide an earthquake damage management system technology that is advantageous in managing damage and recovery from multiple earthquakes in a recovery management list.

[0009] Hereinafter, an embodiment will be described with reference to the drawings. In addition, elements common to the various drawings are given the same reference numerals, and duplicated explanations will be omitted.

[0010] Embodiment 1. Configuration of the elevator earthquake damage management system 1 is a diagram showing the configuration of an earthquake damage management system according to the present embodiment. An elevator to which an 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.

[0011] The elevator system 1 is a system including a plurality of elevators 2. Each elevator 2 is applied to, for example, a building having a plurality of floors. A single building may be provided with a plurality of elevators 2. A hoistway 3 for the elevators 2 is provided in the building. The hoistway 3 is a vertically long space spanning a plurality of floors. In this example, each elevator 2 is a traction type elevator. Note that the elevator system 1 may also include, for example, a drum type elevator and a hydraulic type elevator. The traction type elevator includes a hoist 4, a main rope 5, a car 6, a counterweight 7, an earthquake sensor 8, and a control panel 9.

[0012] The hoisting machine 4 includes a motor that generates a driving force, and a sheave that rotates by the driving force generated by the motor. The hoisting machine 4 is disposed, for example, at the upper or lower part of the hoistway 3. Alternatively, when a machine room is provided in the elevator 2, for example, above the hoistway 3, the hoisting machine 4 may be disposed in the machine room.

[0013] 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 so as to pull up one side of the sheave of the hoisting machine 4 by the driving force generated by the motor of the hoisting machine 4.

[0014] The car 6 is a device that transports passengers of the elevator 2 between multiple floors by traveling up and down the hoistway 3. The counterweight 7 is a device that balances the load of the car 6 on one side of the sheave of the hoisting machine 4 on the other side of the sheave of the hoisting machine 4. The car 6 and the counterweight 7 travel up and down the hoistway 3 in opposite directions as the main rope 5 is moved by the motor of the hoisting machine 4.

[0015] The earthquake sensor 8 is a device that detects earthquake waves in the location where the elevator 2 is installed. The earthquake sensor 8 is disposed, for example, in the elevator shaft 3. Alternatively, if a machine room is provided, the earthquake sensor 8 may be disposed in the machine room.

[0016] The control panel 9 is a device that controls the operation of the elevator 2. The operation of the elevator 2 includes, for example, the running of the car 6. The control panel 9 is arranged, for example, at the upper or lower part of the hoistway 3. Alternatively, if a machine room is provided, the control panel 9 may be arranged in the machine room. The control panel 9 is connected to the devices of the elevator 2 so as to be able to acquire information on the state of the elevator 2 used to control the operation of the elevator 2. The control panel 9 acquires information on the state of the elevator 2 from, for example, sensors or switches provided in the car 6, the hoisting machine 4, or the hoistway 3 of the elevator 2. The control panel 9 acquires information on the detection of seismic waves from the earthquake sensor 8.

[0017] The control panel 9 responds to an earthquake based on the information on the detection of seismic waves obtained from the earthquake sensor 8. Responses to an earthquake include, for example, responses such as controlled operation or operation shutdown. Controlled operation is automatic operation that responds to an earthquake that has occurred. Controlled operation includes diagnostic operation that diagnoses the effects of an earthquake on the elevator 2. Operation shutdown is a response in which the car 6 is stopped and put on standby without traveling.

[0018] Each elevator 2 is equipped with 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 information on the state of the elevator 2 from, for example, the control panel 9.

[0019] An earthquake damage management system 100 is applied to the elevator system 1. The earthquake damage management system 100 is a system that manages 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.

[0020] The central management device 13 is a device that remotely monitors each elevator 2. The central management device 13 is disposed in, for example, an information center 16. The information center 16 is a base for collecting information on the multiple elevators 2. The central management device 13 is, for example, one or a plurality of server devices. The central management device 13 is connected from each remote monitoring device 11 via, for example, an intranet of a maintenance company that operates the earthquake damage management system 100 so that the status of each elevator 2 during normal operation can be communicated.

[0021] The response management device 15 is a device that manages the post-earthquake response status of each elevator 2 installed in an area where seismic motion due to an earthquake has occurred. The response management device 15 is disposed in, for example, an information center 16. The response management device 15 is, for example, one or more server devices. The central management device 13 is connected from each remote monitoring device 11 through, for example, a maintenance company's intranet so that response information of each elevator 2 to an earthquake can be communicated. The response management device 15 is connected to the central management device 13 through, for example, a maintenance company's intranet so that the information on the response status that it manages can be shared. The response management device 15 is connected to a communication network such as the Internet or a telephone line network so that it can receive information from an external service 19. The external service 19 is, for example, a service outside the earthquake damage management system 100 that distributes earthquake information. The external service 19 is provided by a public institution such as the Japan Meteorological Agency in Japan or a similar institution in another country, or a private institution.

[0022] The response management device 15 includes an earthquake information receiving unit 20, a response information receiving unit 21, a memory unit 22, a progress information receiving unit 23, a list management unit 24, a compilation unit 25, a photo data receiving unit 26, and an overhead display unit 27.

[0023] 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 for a target area in which at least one of the multiple elevators 2 is installed from the external service 19. The earthquake information is distributed from the external service 19 when an earthquake occurs. The earthquake information includes information such as the area where the earthquake occurred, the time when the earthquake occurred, and the magnitude of the earthquake that occurred. The magnitude of the earthquake includes, for example, information on the seismic intensity scale. The earthquake information may 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 magnitude of the earthquake. The magnitude of the earthquake includes, for example, information on the magnitude. The received earthquake information is recorded in the memory unit 22.

[0024] The response information receiving unit 21 is a part that receives information regarding the elevator 2's response to an 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 controlled operation or operation suspension of the elevator 2, and identification information that identifies the elevator 2. The identification information that identifies the elevator 2 is, for example, information such as the building number of the building in which the elevator 2 is installed, and the elevator 2's car number that is uniquely set in the building.

[0025] The memory unit 22 is a part that stores a restoration management list, a property damage management list, and a history list. The restoration management list is a list of management information used to manage post-earthquake responses for each elevator 2 installed in the target area where the earthquake occurred. The property damage management list is a list for extracting from the restoration management list and managing management information for elevators 2 where property damage has occurred. The history list is a list for accumulating and managing management information for elevators 2 for which restoration has been completed.

[0026] The progress information receiving unit 23 is a part that receives progress information indicating the response status of the elevator 2. The progress information includes operations by a maintenance worker through the maintenance terminal 18. The operations received by the progress information receiving unit 23 include, for example, an operation to input information about the status of the response status after an earthquake. The response status includes, for example, whether the elevator 2 has not yet been restored, whether restoration is in progress, whether restoration has been completed, whether there has been any property damage, the state of the property damage, etc.

[0027] The list management unit 24 is a part that manages the restoration management list, the property damage management list, and the history list. The list management unit 24 registers management information of elevators that require post-earthquake response management among the multiple elevators 2 in the restoration management list. The list management unit 24 registers earthquake information in the restoration management list in association with the management information. Furthermore, the list management unit 24 registers post-earthquake progress information in the management target list in association with the management information.

[0028] The list management unit 24 moves management information of elevators where property damage has occurred, among the management information registered in the restoration management list, to the property damage management list. In addition, the list management unit 24 moves management information of elevators for which restoration has been completed, among the management information registered in the restoration management list or the property damage management list, to the history list at a specified timing.

[0029] The counting unit 25 is a part that counts the management information registered in the recovery management list. The counting unit 25 counts the management information, for example, for each earthquake. For example, the counting unit 25 counts the number of elevators registered in the recovery management list and the number of elevators among those for which post-earthquake response has been completed, for each earthquake. In addition, the counting unit 25 counts the number of cases of people being trapped in elevators registered in the recovery management list and the number of cases of people being trapped among those for which rescue has been completed, for each earthquake.

[0030] The photograph data receiving unit 26 is a part that receives photograph data of the restoration site transmitted from the maintenance terminal 18. The photograph data includes a photograph of the restoration site taken by a maintenance worker and information for identifying the position of the restoration site.

[0031] The bird's-eye view display unit 27 is a part for displaying various pieces of management information registered in the recovery management list, the item list, and the history list on a map. The process performed in the bird's-eye view display unit 27 is hereinafter referred to as "bird's-eye view display process." Examples of information displayed in the bird's-eye view display process include recovery rate, progress information, photo data, etc.

[0032] 2. Example of operation of the Earthquake Damage Management System 100 Next, an example of the operation executed in the earthquake damage management system 100 will be described.

[0033] 2-1.Basic operation The basic operations executed by the response management device 15 of the earthquake damage management system 100 will be described below using an example in which earthquake A occurs in the target area where the elevator 2 is installed. FIG. 2 is a diagram showing the contents of the response screen for each time in the recovery management list after an earthquake occurs. On the time axis shown in FIG. 2, "occurrence convergence" indicates the time when the acceptance of the occurrence of damage caused by earthquake A based on response information converges to a specified level, "restoration start" indicates the time when restoration work by maintenance personnel begins, "restoration convergence" indicates the time when all damage caused by earthquake A other than property damage is restored, and "full restoration completion" indicates the time when all damage caused by earthquake A, including property damage, is restored.

[0034] 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. Usually, the number of received response information per hour increases sharply immediately after the occurrence of earthquake A, but then converges toward zero as time passes. Upon receiving the response information, the list management unit 24 registers management information including the response information of the elevator 2 that needs to be managed after the earthquake 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 each management information in association with progress information. In the example of FIG. 2, the elevators 2 in the AA building, BB building, CC building, and DD building are shown, and their respective response contents indicate that they are out of operation, and that no action has been taken by maintenance personnel yet.

[0035] In addition, in the recovery list registration process, the list management unit 24 registers information on earthquakes that are directly related to the response in association with each piece of registered management information. The example in Fig. 2 shows a case where "Earthquake A" is registered in association with the elevators 2 in the AA building, the BB building, the CC building, and the DD building.

[0036] The tallying unit 25 tallys up information on the recovery management list by branch / office, the number of outages / recoveries, the number of property damages, etc., by earthquake, and displays it on the in-progress screen. This process is hereinafter referred to as the "list tallying process." The maintenance manager sets up a recovery system by referring to the in-progress screen. Each maintenance worker performs damage status confirmation work and recovery work while checking the progress of recovery on the in-progress screen. At this time, each maintenance worker appropriately inputs progress information including the post-earthquake response status through the maintenance terminal 18. The list management unit 24 updates the management information as needed based on the progress information received by the progress information receiving unit 23.

[0037] In the restoration management for earthquake A, when restoration of all elevators including property damage is completed, the list management unit 24 moves all the management information registered in the restoration management list in association with earthquake A to the history list. This process is hereinafter referred to as "history list moving process." As a result, the response screen of the restoration management list for earthquake A becomes empty.

[0038] 2-2. Characteristic operations in the recovery list registration process In the above-described basic operation, there is a risk of malfunction in the restoration list registration process when multiple earthquakes occur in a short period of time in the target area where the elevator 2 is installed. That is, the timing at which the response information receiving unit 21 receives the response information is not necessarily immediately after the occurrence of an earthquake. That is, the reception of the response information may be delayed due to communication delays caused by the effects of an earthquake, for example. In addition, when the building manager notifies the occurrence of damage by telephone, it is considered that the manager cannot contact the manager promptly after the earthquake. In this way, although the number of response information received per hour after the occurrence of an earthquake increases sharply immediately after the earthquake, it is considered that a certain period of time is required for the occurrence to converge thereafter. On the other hand, it is required to associate the name of the earthquake that is directly related to the damage with the response information. However, when multiple earthquakes occur at short intervals, there is a risk that it is not possible to determine whether the response information received after the current earthquake corresponds to the previous earthquake or the current earthquake.

[0039] In the earthquake damage management system 100 of this embodiment, in the recovery list registration process, if the previous earthquake and the current earthquake occur in sequence with an interval between them, the earthquake to be associated with the response information received after the current earthquake is determined depending on whether the current earthquake occurs before or after the previous earthquake has subsided.

[0040] Figures 3 and 4 are diagrams for explaining how the earthquake damage management system associates earthquakes with response information. In the examples shown in these figures, earthquake A occurred as the previous earthquake, and earthquake B occurred as the current earthquake. The example shown in Figure 3 illustrates a case where earthquake B occurred before earthquake A subsided. The example shown in Figure 4 illustrates a case where earthquake B occurred after earthquake A subsided.

[0041] If earthquake B occurs before earthquake A has subsided, the list management unit 24 associates earthquake A with the response information received after earthquake B. On the other hand, if earthquake B occurs after earthquake A has subsided, the list management unit 24 associates earthquake B with the response information received after earthquake B.

[0042] The determination of occurrence convergence can be performed, for example, by calculating an index value for determining occurrence convergence and comparing the index value with a threshold value. The index value is, for example, an occurrence rate represented by the number of response information received per unit time. If the occurrence rate is smaller than the threshold value, the list management unit 24 determines occurrence convergence. The occurrence rate is considered to change with a tendency according to the day of the week or time period when the earthquake occurs. That is, some buildings are not in operation on holidays or at night, and response information may be received after the holiday or at the end of the night. That is, the period until occurrence convergence tends to be longer on holidays or at night than on weekdays or during the day. In addition, if a failure occurs in a communication line after an earthquake occurs, the reception of response information may be delayed. Even in this case, the period until occurrence convergence may be longer. Therefore, the threshold value of the occurrence rate may be changed according to the day of the week, time period, and the presence or absence of communication failure when the earthquake occurs.

[0043] According to the above operation, even if multiple earthquakes occur in succession, the response information can be associated with the earthquake name. Hereinafter, a specific process in which the response management device 15 associates the response information with the earthquake name will be described.

[0044] 5 is a flowchart showing a routine for recording earthquake information executed by the response management device 15. In step S10, the earthquake information receiving unit 20 judges whether an earthquake of seismic intensity 4 or more has occurred based on the earthquake information received from the external service 19. From past records, it is considered that most elevators will not stop operating if the earthquake's seismic intensity is 3 or less. Therefore, if the judgment is not established, in order to reduce the load on the system, the earthquake information is not recorded and this routine is terminated.

[0045] On the other hand, if the judgment in step S10 is found to be successful, the process proceeds to step S12. In step S12, earthquake information of the earthquake of seismic intensity 4 or more found to have occurred in step S10 is recorded after undergoing generation management. Here, the earthquake information receiving unit 20 compares the degree of coincidence between the area of ​​the new earthquake of seismic intensity 4 or more found to have occurred in step S10 and the area of ​​the recorded current earthquake. If the coincidence rate is equal to or less than a specified value (e.g., 30%), it is determined that the earthquake is different from the recorded current earthquake, and the current earthquake is set as the previous earthquake, the previous earthquake is set as the earthquake before last, and the new earthquake is recorded in the memory unit 22 as the current earthquake. On the other hand, if the coincidence rate is greater than the specified value, it is determined that the earthquake is the same as the recorded current earthquake, and the newly recorded new earthquake is recorded in the memory unit 22 as part of the current earthquake.

[0046] Fig. 6 is a flowchart showing a routine of a recovery list registration process executed in the response management device 15. In step S100 of the routine shown in Fig. 6, it is determined whether or not the response information receiving unit 21 has received response information. If the determination is not satisfied, the routine is terminated, and if the determination is satisfied, the process proceeds to step S102.

[0047] 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 converged at the time of the occurrence of the current earthquake. Here, the list management unit 24 calculates the occurrence rate of the previous earthquake at the time of the occurrence of the current earthquake, and determines whether the calculated occurrence rate is smaller than a threshold value. If the result shows that the determination is not true, the process proceeds to step S106, and if the result shows that the determination is true, the process proceeds to step S108.

[0048] In step S106, the list management unit 24 registers the information on the previous earthquake in association with the management information of the target elevator 2. In step S108, it is determined whether the occurrence of the current earthquake has converged. Here, the list management unit 24 calculates the occurrence rate after the occurrence of the current earthquake, and determines whether the calculated occurrence rate is smaller than a threshold value. The threshold value here is a threshold value that is predefined for determining whether the occurrence of the current earthquake has converged, and for example, the number of occurrences per unit time (for example, n occurrences / m minutes) is used. As a result, if the determination is found to be true, it is determined that the occurrence of the current earthquake has converged, and the process proceeds to step S110, and if the determination is not found to be true, it is determined that the occurrence of the current earthquake has not converged, and the process proceeds to step S112.

[0049] In step S110, it is determined that there is a possibility of an erroneous judgment in the automatic judgment by the system, and the earthquake name to be associated with the management information is set to "unknown", and the earthquake to be associated with the management information is determined by human judgment. In step S112, the list management unit 24 registers the current earthquake in association with the management information of the target elevator 2.

[0050] According to the above process, it is possible to determine whether to associate the response information received after the current earthquake with the previous earthquake, the current earthquake, or "unknown." This makes it possible to associate the name of each earthquake with the management information even when earthquakes occur one after another in succession.

[0051] 2-3.Characteristic behavior in history list transfer processing In the history list moving process, which is a basic operation described above, when all the management information of the elevators associated with Earthquake A in the recovery management list, including the property damage, is completed, all of this management information is moved to the history list. However, with this operation, if the recovery of the property damage takes a long time, the elevators that have been restored will remain in the recovery management list for a long time without being moved, which creates problems such as making the recovery management list response screen difficult to see and misinterpreting the damage situation.

[0052] Therefore, in the earthquake damage management system 100 of this embodiment, among the elevator management information registered in the restoration management list, elevator management information associated with property damage is moved to the property damage management list. This process is hereinafter referred to as the "property damage management list moving process." This makes it possible to move the elevator management information registered in the restoration management list to the history list without waiting for the restoration of the damaged elevator. This improves the visibility of the response screen, improving usability for maintenance personnel.

[0053] The management information of the elevators moved to the property damage management list by the property damage management list moving process is updated from time to time based on the progress information. The management information of the elevators that have been restored is moved from the property damage management list to the history list.

[0054] Fig. 7 is a flowchart showing a routine of a history list moving process executed in the response management device 15. The routine shown in Fig. 7 is executed for each of the recovery management lists registered for each earthquake. Here, the process executed for the recovery management list for earthquake A is illustrated.

[0055] In step S200 of the routine shown in Fig. 7, the list management unit 24 updates the management information registered in the restoration management list for earthquake A based on the progress information received by the progress information receiving unit 23. In step 202, the list management unit 24 judges whether or not management information of the elevator that caused the property damage is registered in the restoration management list. If the judgment is not satisfied, the process proceeds to step S206, and if the judgment is satisfied, the process proceeds to step S204.

[0056] In step S204, the list management unit 24 moves the management information of the elevator with property damage from the restoration management list to the property damage management list. When the processing of step S204 is completed, the processing proceeds to step S206. In step S206, the list management unit 24 judges whether the restoration of all elevators registered in the restoration management list of earthquake A has been completed. As a result, if the judgment is found to be true, the processing proceeds to step S208, and if the judgment is found to be false, this routine is terminated. In step S208, the list management unit 24 moves all management information of elevators for which restoration has been completed to the history list. When the processing of step S208 is completed, this routine is terminated.

[0057] 2-4. First example of history list transfer process Next, a first specific example of the history list movement process will be described. FIG. 8 is a diagram illustrating a part of the recovery management list when earthquake A occurs. Note that there are multiple items in the recovery management list shown below other than the items shown in the figure, but they are not described here. In the example shown in this figure, earthquake A with a seismic intensity of 4 occurs in the target area XX at time 10:00. In response to earthquake A, the list management unit 24 registers the contents of the response information received by the response information receiving unit 21 in the recovery management list as management information. The recovery management list shown in FIG. 8 is compiled for each associated earthquake. When earthquake A occurs, the recovery management list of earthquake A as the latest earthquake is displayed on the response screen by default. The recovery management list with the earthquake name "none" is a list in which management information of elevators that need to be restored due to earthquakes with a seismic intensity of 3 or less or reasons other than earthquakes is registered.

[0058] FIG. 9 is a diagram illustrating a part of the recovery management list at the start of recovery. In the example shown in this figure, recovery starts at 10:30. Maintenance personnel check the damage situation at each site and input progress information including the response situation after the earthquake as appropriate through the maintenance terminal 18. The list management unit 24 updates the management information as needed based on the progress information received by the progress information receiving unit 23. In the example shown in FIG. 9, 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 associated with the property damage to the property damage management list. FIG. 10 is a diagram illustrating the property damage management list. As shown in this figure, the management information of Unit 001 of the EE building that was registered in the recovery management list is moved to the property damage management list.

[0059] Fig. 11 is a diagram illustrating a portion of the recovery management list upon completion of recovery. The example shown in this diagram illustrates a case where all recovery for earthquake A is completed at 12:00 the following day. In this case, the list management unit 24 moves all management information in the recovery management list for earthquake A to the history list. Fig. 12 is a diagram illustrating a portion of the history list. As shown in this diagram, information on elevators that have been restored is accumulated and managed in the history list.

[0060] 13 is a diagram illustrating an example of the property damage management list. When an elevator registered in the property damage management list is restored, the list management unit 24 moves management information of the restored elevator to the history list.

[0061] According to the above-mentioned operation, the management information of elevators that have been damaged and may require a long time to be restored can be managed in a damage management list that is separate from the restoration management list, thereby preventing elevators that have been damaged from remaining in the restoration management list for a long period of time.

[0062] 2-5. Second example of history list transfer process Next, a second specific example of the history list movement process will be described. FIG. 14 is a diagram illustrating a part of the recovery management list at the time of the occurrence of earthquake B. In the example shown in this figure, earthquake B with a seismic intensity of 6 occurs in the target area XX at 11:00 after the start of recovery from earthquake A shown in FIG. 10. In response to earthquake B, the list management unit 24 registers management information including the response information received by the response information receiving unit 21 in the recovery management list. The recovery management list shown in FIG. 14 is compiled for each associated earthquake. When earthquake B occurs, the recovery management list of earthquake B as the latest earthquake is displayed on the response screen by default. In the example of the recovery management list shown in FIG. 14, the elevator in AA building, which was restored after being stopped in operation due to earthquake A, is stopped again in operation due to earthquake B. In addition, in the example of the recovery management list shown in FIG. 14, the elevators in CC building, DD building, and FF building, which were not stopped in operation due to earthquake A, are stopped in operation due to earthquake B.

[0063] Figure 15 is a diagram showing an example of a part of the recovery management list when recovery has been converged. The example shown in this figure shows a case where all recovery for earthquake B has been completed at 13:00 the following day. Note that since the recovery management list for earthquake A has been converged at 12:00, the recovery management list for earthquake A has already been deleted.

[0064] The list management unit 24 moves all elevators in the restoration management list for earthquake B to the history list. Fig. 16 is a diagram illustrating a part of the history list. As shown in this diagram, management information of elevators that have been restored is managed in the history list.

[0065] The history list is used, for example, when reporting damage after each earthquake. The counting unit 25 counts the management information of stopped elevators for each earthquake. The counting result is used, for example, in reporting in response to a request from an administrative agency.

[0066] 2-6. Characteristic behavior of overhead display processing In the bird's-eye view display process, the bird's-eye view display unit 27 displays, for example, part of the management information of the recovery management list on a map in a bird's-eye view. FIG. 17 is a diagram showing an example of the contents of the recovery management list displayed in a bird's-eye view on a map. In the example shown in this figure, icons selected for display are arranged on a map including the target area. Examples of the icons displayed here include a restored elevator, an elevator where property damage occurred, and a business office. The business office icon visually represents the recovery rate of elevators in its jurisdiction and the attendance rate of buildings in its jurisdiction. Maintenance personnel check the damage status and response status of the target area while referring to these bird's-eye views.

[0067] The icons that can be displayed on the map are not limited to those shown in Fig. 17. That is, the tabulation unit 25 can display and select a wide range of icons of information, such as trapped, power outage, flood, etc., that are tabulated in the restoration management list.

[0068] When the icon of the business establishment is clicked, the bird's-eye view display unit 27 displays a detailed display screen in which the results are tabulated by business establishment. Fig. 18 is a diagram showing an example of a detailed display screen by business establishment. In the example shown in this figure, the automatic tabulation results of elevators and personnel are displayed. The maintenance staff can check the detailed response status by referring to the detailed display screen.

[0069] Furthermore, photo data of the restoration site may be associated with the icon on the map. For example, a maintenance worker takes a photo of the restoration site of an elevator where property damage has occurred, adds location information to the photo data, and transmits 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 transmitted from the maintenance terminal 18. The received photo is associated with an icon of the corresponding elevator location. When the icon is clicked, the overhead display unit 27 displays the associated photo. This process allows the maintenance worker to easily check the photo of the restoration site on the display screen.

[0070] 4. Variations The earthquake damage management system 100 of this embodiment may be modified as follows.

[0071] 4-1.Hardware resources of the Earthquake Damage Management System 100

[0072] 19 is a diagram showing an example of hardware resources of the earthquake damage management system 100. The response management device 15 of the earthquake damage management system 100 has, as hardware resources, a processing circuit 34 including a processor 30 and a memory 32. The processing circuit 34 may include multiple processors 30. The processing circuit 34 may include multiple memories 32.

[0073] In this embodiment, each of the units indicated by the reference numerals 20 to 27 indicates a function possessed by the response management device 15. The function of the storage unit 22 is realized by the memory 32. The function of each of the units indicated by the reference numerals 20 to 27 can be realized by software written as a program, firmware, or a combination of software and firmware. The program is stored in the memory 32. The response management device 15 realizes the function of each of the units indicated by the reference numerals 20 to 27 by executing the program stored in the memory 32 by the processor 30 (computer).

[0074] The processor 30 is also called a CPU (Central Processing Unit), central processing unit, processing unit, arithmetic unit, microprocessor, microcomputer, or DSP. The memory 32 may be a semiconductor memory, a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, or a DVD. Possible semiconductor memories include RAM, ROM, flash memory, EPROM, and EEPROM.

[0075] Fig. 20 is a diagram showing another example of hardware resources of the earthquake damage management system 100. In the example shown in Fig. 20, the response management device 15 includes a processor 30, a memory 32, and a processing circuit 34 including dedicated hardware 36. Fig. 20 shows an example in which some of the functions of the response management device 15 are realized by the dedicated hardware 36. All of the functions of the response management device 15 may be realized by the dedicated hardware 36. As the dedicated hardware 36, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination of these can be used.

[0076] In areas where the seismic intensity of the current earthquake, Earthquake B, is greater than that of the previous earthquake, Earthquake A, it is expected that elevators that stopped operating in Earthquake A will also stop operating when Earthquake B occurs. Therefore, the list management unit 24 may further associate Earthquake B with elevators that have already stopped operating due to Earthquake A when Earthquake B occurs. This type of processing makes it possible to tally up the scale of damage caused by Earthquake B alone when making a damage report after the fact.

[0077] The central management device 13 is not essential to the earthquake damage management system 100. If the earthquake damage management system 100 does not have the central management device 13, the response management device 15 in the information center 16 is connected from each remote monitoring device 11 via, for example, a maintenance company's intranet.
