  The time update unit 16 updates the rescue time according to, for example, the arrival of the maintenance worker in the confinement accident and the progress of the rescue operation defined in the rescue operation list. The rescue time updated by the time update unit 16 is transmitted to the display control device 20 via the communication processing unit 15.

  Next, the operation of the maintenance management apparatus 10 according to the present embodiment will be described. First, the processing procedure of the maintenance management apparatus 10 when displaying the rescue time described above on the liquid crystal monitor 22 will be described with reference to the flowchart of FIG.

  When a confinement accident occurs while a passenger is in the car 21, the monitoring terminal provided in the elevator transmits accident occurrence information indicating the occurrence of the confinement accident to the maintenance management device 10. To do. This accident occurrence information includes the cause of the confinement accident (for example, an elevator failure location).

  The accident determination unit 11 determines whether or not accident occurrence information has been received via the communication processing unit 15 (step S1). When the accident occurrence information is received (YES in step S1), the accident determination unit 11 determines that a confinement accident has occurred in the elevator.

  Note that an interphone is provided in the car 21 as described above. Therefore, when a confinement accident occurs while a passenger is in the car 21, the passenger can press the emergency call button or the like provided in the car 21 via the interphone. It is possible to notify the monitoring center manager of the occurrence of a confinement accident. The accident determination unit 11 may determine that a confinement accident has occurred according to the operation of the administrator who has received such communication.

  Here, the maintenance management device 10 (the communication processing unit 15 included therein) periodically receives position information (current position of the maintenance staff) from the portable terminal 30 possessed by the maintenance staff. Thus, when it is determined that a confinement accident has occurred, the maintenance management device 10 indicates that the confinement accident has occurred at a position corresponding to the address of the confinement accident occurrence site (hereinafter referred to as the accident occurrence site). A map (information) in which an icon representing the maintenance engineer is disposed at a position indicated by the position information received from the mobile terminal 30 is displayed. The address of the site where the confinement accident occurs is acquired from the elevator information stored in the maintenance management information storage unit 13. The map information displayed on the maintenance management device 10 is acquired from the map information storage unit 12.

  The manager of the monitoring center that uses the maintenance management device 10 sends a maintenance staff (indicating an icon) located relatively close to the accident occurrence site to the maintenance site (hereinafter referred to as a maintenance engineer in charge). Can be specified on the map displayed on the maintenance management device 10 (step S2).

  When the maintenance engineer is designated by the administrator, a telephone number included in the maintenance staff information stored in the maintenance management information storage unit 13 is transmitted from the maintenance management apparatus 10, and the administrator who uses the maintenance management apparatus 10 Calls can be made with the maintenance staff in charge. Thus, the manager can instruct the responsible maintenance staff to rescue the passenger at the accident occurrence site. The maintenance engineer in charge moves to the accident site according to instructions from the administrator.

  The instruction from the administrator may be performed by sending e-mail or the like to the portable terminal 30 possessed by the maintenance staff in charge.

  Next, in the maintenance management device 10, a means (hereinafter referred to as transportation means) for the maintenance staff in charge to move to the accident occurrence site is specified (step S3). Examples of transportation include walking, bicycles, cars, and motorcycles. In step S3, the means of transportation input by the administrator to the maintenance management device 10 may be specified in accordance with the content of the call with the maintenance engineer described above, or predetermined for the maintenance engineer. A means of transportation may be specified. When a transportation means is predetermined for the maintenance staff in charge, it is assumed that the transportation means is stored in the maintenance management information storage unit 13 as maintenance staff information. In this case, the transportation means can be specified based on the maintenance staff information stored in the maintenance management information storage unit 13. Hereinafter, the transportation means specified in step S3 is referred to as a target transportation means for convenience.

  The arrival time calculation unit 141 included in the rescue time calculation unit 14 includes the position information (that is, the current position of the maintenance staff in charge) received from the portable terminal 30 possessed by the maintenance staff in charge, the position (address) of the accident occurrence site, and Based on the map information stored in the map information storage unit 12 and the target transportation means, the estimated arrival time is calculated (step S4).

  In this case, the arrival time calculation unit 141 calculates the route (shortest route) from the current position of the maintenance engineer in charge to the location of the accident occurrence site based on the map information, and depends on the distance of the route and the target transportation means on the route. The arrival time is calculated using the moving speed (speed limit) or the like. In the arrival time calculation process, for example, various types of traffic information (such as traffic jam information) acquired from an external server device or the like may be used.

  Next, the rescue work list generation unit 142 refers to the maintenance management information storage unit 13 and rescues in which rescue work corresponding to the cause of the confinement accident included in the accident occurrence information received from the monitoring terminal is defined. A work list is generated (step S5). In this case, the rescue work list generation unit 142 causes the confinement accident to occur (for example, part failure, etc.) from among the work items indicated by each of the plurality of work information stored in the maintenance management information storage unit 13. ), And a plurality of work items necessary to restore the elevator (that is, rescue the passenger) are selected, and a rescue work list including the selected work items is generated. It is assumed that a plurality of work items included in the rescue work list are arranged in the order in which work is performed.

  The rescue work time calculation unit 143 calculates the rescue work time based on the work time set for each work item included in the rescue work list (step S6). Specifically, the rescue work time calculation unit 143 calculates the total work time set for each work item included in the rescue work list as the rescue work time. Depending on the work item (the work corresponding to), preparation before performing the work or movement of the work place may be necessary. Therefore, in these cases, the rescue work time calculated as described above The time obtained by adding the necessary time may be calculated as the rescue work time. The time to be added may be different depending on the structure of the building where the elevator is installed (that is, ease of work).

  The rescue time calculation unit 14 calculates a rescue time based on the arrival time calculated by the arrival time calculation unit 141 and the rescue work time calculated by the rescue work time calculation unit 143 (step S7). Assuming that the rescue time is expected to be required from the occurrence of the confinement accident until the passenger is rescued, the rescue time calculation unit 14 calculates the total time of the arrival time and the rescue work time as the rescue time. The maintenance staff in charge may not be able to start rescue work immediately after arriving at the accident site due to rescue work preparation, etc., so the time set in advance for the total time of arrival time and rescue work time The time obtained by adding (for example, about several minutes) may be the rescue time.

  The rescue time (arrival time and rescue work time) calculated by the rescue time calculation unit 14 is held inside the maintenance management device 10.

  Next, the communication processing unit 15 transmits the rescue time calculated by the rescue time calculation unit 14 to the display control device 20 (step S8).

  When the process of step S <b> 8 is executed, the display control device 20 receives the rescue time transmitted by the communication processing unit 15 and displays the rescue time on the liquid crystal monitor 22 in the car 21. Specifically, the rescue time is displayed as, for example, “Schedule to rescue after about XX minutes. Please wait for a while”. The rescue time is, for example, “The maintenance staff will arrive at the site after about △△ minutes (arrival time). After the maintenance staff arrives at the site, it will be rescued after about xx minutes (rescue work time). “Please wait for a while.” Each of the arrival time and the rescue work time may be displayed in a distinguishable manner.

  In addition, the communication processing unit 15 transmits the rescue work list generated by the rescue work list generation unit 142 to the portable terminal 30 owned by the maintenance staff in charge. The rescue work list transmitted to the mobile terminal 30 can be displayed on the display of the mobile terminal 30. In the rescue work list, the plurality of work items are arranged in the order in which the work is performed, so that the maintenance engineer in charge can perform the rescue work along the work items.

  On the other hand, when it is determined in step S1 that the accident occurrence information has not been received (NO in step S1), the process of the maintenance management device 10 is ended.

  Here, the rescue time displayed on the liquid crystal monitor 22 by executing the processing shown in FIG. 3 described above is a time that is expected to be required until the passenger is rescued from the occurrence of the confinement accident. The maintenance staff needs to be updated according to the arrival status of the accident and the progress of the rescue operation.

  A processing procedure of the maintenance management apparatus 10 when updating the rescue time displayed on the liquid crystal monitor 22 will be described with reference to the flowchart of FIG. The process shown in FIG. 4 is executed after the process shown in FIG. 3 described above is executed and the rescue time is displayed on the liquid crystal monitor 22.

  First, the time updating unit 16 determines whether or not the responsible maintenance staff has arrived at the accident occurrence site (step S11). The maintenance engineer can notify the maintenance management device 10 that the maintenance engineer has arrived at the accident occurrence site, for example, by operating the portable terminal 30 possessed by the maintenance engineer. The time update unit 16 determines that the maintenance staff in charge has arrived at the accident occurrence site based on the notification from the portable terminal 30.

  As described above, since the maintenance management device 10 periodically receives the position information from the portable terminal 30 possessed by the maintenance engineer in charge, the time update unit 16 indicates the current status of the maintenance engineer in charge indicated by the position information. Based on the position, it may be determined that the responsible maintenance staff has arrived at the accident occurrence site.

  If it is determined that the responsible maintenance engineer has not arrived at the accident occurrence site (NO in step S11), the process returns to step S11 and is repeated.

  On the other hand, when it is determined that the maintenance engineer has arrived at the accident occurrence site (YES in step S11), the time updating unit 16 determines whether the maintenance engineer 10 Is updated (that is, the rescue time displayed on the liquid crystal monitor 22) (step S12).

  Specifically, the time update unit 16 updates the rescue time by subtracting the arrival time from the rescue time held in the maintenance management apparatus 10. In this case, the rescue time after the update by the time update unit 16 corresponds to the rescue work time calculated in the process shown in FIG. Hereinafter, the rescue time after the update by the process of step S12 is referred to as the first rescue time after the update for convenience. The rescue time after the first update is held inside the maintenance management device 10.

  Next, the communication processing unit 15 transmits the first updated rescue time to the display control device 20 (step S13).

  When the process of step S13 is executed, the display control device 20 receives the first updated rescue time transmitted by the communication processing unit 15, and displays the rescue time on the liquid crystal monitor 22 in the car 21. To do. The rescue time after the first update in this case is displayed as, for example, “The maintenance engineer in charge has arrived at the scene. The rescue is scheduled in about xx minutes. Please wait.”

  Here, as described above, the maintenance engineer can perform rescue work along a plurality of work items included in the rescue work list displayed on the display of the mobile terminal 30. In this case, the maintenance engineer completes the work item by operating the portable terminal 30 when one of the work items included in the rescue work list is completed (the work corresponding to the work item). Can be registered. Completion of the work item registered in this way is notified from the portable terminal 30 to the maintenance management device 10.

  The time update unit 16 determines whether one work item among a plurality of work items included in the rescue work list has been completed based on the presence / absence of a notification from the mobile terminal 30 (step S14).

  When the completion of the work item is not notified from the portable terminal 30, the time update unit 16 repeats the process of step S14 until the completion of the work item is notified (NO in step S14).

  On the other hand, when the completion of the work item is notified from the portable terminal 30, the time update unit 16 determines that the work item is completed (YES in step S14). In this case, the time update unit 16 sets the first updated rescue time (that is, the rescue time displayed on the liquid crystal monitor 22) held in the maintenance management device 10 in accordance with the completion of the work item. Update (step S15).

  Specifically, the time update unit 16 updates the work time by subtracting the work time set in advance for the completed work item from the rescue time after the first update. Hereinafter, the rescue time after update by the process of step S15 is referred to as a second rescue time after update for convenience. The rescue time after the second update is held inside the maintenance management device 10.

  Next, the communication processing unit 15 transmits the second updated rescue time to the display control device 20 (step S16).

  When the process of step S <b> 16 is executed, the display control device 20 receives the second updated rescue time transmitted by the communication processing unit 15 and displays the rescue time on the liquid crystal monitor 22 in the car 21. To do. The rescue time after the second update in this case is displayed as, for example, “Currently rescue operation is in progress. Rescue is scheduled in about □□ minutes. Please wait.” In this case, the completed work item among the plurality of work items included in the rescue work list described above may be displayed on the liquid crystal monitor 22 so that the passenger can grasp the progress of the rescue work.

  Next, in the maintenance management device 10, it is determined whether or not the rescue operation has been completed (step S17). In this case, when the completion of all the work items included in the rescue work list is notified from the portable terminal 30, it is determined that the rescue work has been completed.

  When it is determined that the rescue operation has not been completed (NO in step S17), the process returns to the above-described step S14 and is repeated. In this case, when another work item is completed, the rescue time after the second update held in the maintenance management apparatus 10 is further updated in step S15.

  On the other hand, when it is determined that the rescue operation has been completed (YES in step S17), the process of the maintenance management device 10 is terminated. In this case, when the maintenance management device 10 notifies the display control device 20 of the completion of the rescue operation, the display control device 20 displays a message such as “Rescue operation has been completed. It may be displayed on the liquid crystal monitor 22.

  In the processing shown in FIG. 3 described above, it has been described that the arrival time and the rescue work time are displayed as the rescue time on the liquid crystal monitor 22 in the car 21, but in the case where there are many maintenance personnel, Maintenance personnel can often reach the accident site in a short time. Therefore, the maintenance management apparatus 10 according to the present embodiment may be configured to display only the rescue work time as the rescue time. In this case, the processes in steps S2 to S4 shown in FIG. 3 are omitted.

  Further, when a configuration in which only the rescue work time is displayed is adopted, the rescue work time is displayed at the time when it is determined that the maintenance engineer in charge has arrived at the accident occurrence site in the process shown in step S11 shown in FIG. It is good also as a structure displayed on the monitor 22. FIG.
