  The building information acquisition unit 110 acquires information about the building where the target EV is installed as building information. The building information acquisition unit 110 includes a building information DB 111 and a building information extraction unit 112. It is assumed that the building information DB 111 stores a plurality of building information tables (not shown) for each building. The building information on the building information table includes, for example, the name of the target building, the address of the building, the specification of the target EV installed in the building, the identification information of the target EV, the business day of the building, holidays, business hours, lunch break This includes, but is not limited to, time of visit, visit time of the customer, absence of the manager on the side of the building, implementation date of maintenance inspection, person in charge of maintenance inspection (maintenance worker), and the like. The building information extraction unit 112 refers to the building information DB 111 and extracts the building information corresponding to the building where the target EV is installed. Part or all of the building information extracted by the building information extraction unit 112 is transmitted to the identification information acquisition device 202 and the prescribed work time information DB 81. The building information stored in the building information DB 111 is updated at any time when a change occurs in the item of the building information and new data is input, or is updated periodically.

  The control panel 201 and the identification information acquisition apparatus 202 can communicate with the maintenance work support apparatus 100 by wire or wireless, and constitute an elevator maintenance work support system together with the maintenance work support apparatus 100.

  The specification acquisition unit 1 acquires the specification of the target EV based on the identification information acquired from the identification information acquisition device 202. The specification acquisition unit 1 includes a specification DB 11 and a specification extraction unit 12.

In FIG. 2, the record of each elevator apparatus EV includes three specifications: model, lifting speed, and installation floor. According to FIG. 2, for example, the model of the elevator apparatus EV1 is A.

  The specification extraction unit 12 acquires the identification information of the target EV from the identification information acquisition device 202, and extracts the specification information corresponding to the acquired identification information from the specification DB 11. For example, when the identification information (ID = EV1) of the elevator apparatus EV1 is acquired, the specification extraction unit 12 extracts the record of EV1 from the specification table of FIG. Thereby, the model A, the raising / lowering speed 30, and the installation floors 1 to 10 are extracted as the specifications of the target EV.

  The ideal timing acquisition unit 2 acquires ideal timing. The ideal timing is a time that satisfies a predetermined condition when a normal elevator apparatus EV performs an operation specified by an operation command. The predetermined conditions are, for example, the end of the operation command (end of the operation specified by the operation command), the elevating speed being a predetermined value, the basket passing through a predetermined position between the floors, and the door being fully open or Although it is at least one of becoming fully closed, it is not restricted to this. The ideal timing acquisition unit 2 includes an ideal operation time DB 21 and an ideal timing calculation unit 22.

  The ideal operation time DB 21 stores ideal operation time. The ideal operation time is a time required for a normal elevator apparatus EV to perform a certain operation. The ideal operation time is set or measured in advance and stored for each specification of the elevator apparatus EV.

  Here, FIG. 3 is a diagram illustrating an example of an ideal operation time table (ideal operation time information) stored in the ideal operation time DB 21. As shown in FIG. 3, the ideal operation time DB 21 stores the operation of the elevator apparatus EV and the ideal operation time in association with each other. According to FIG. 3, for example, the ideal operation time until the cage rises from the first floor to the second floor is 5 seconds. This indicates that, when the elevator apparatus EV is normal, it takes 5 seconds for the basket to rise from the first floor to the second floor. The ideal operation time DB 21 stores such an ideal operation time table for each specification of the elevator apparatus EV.

First, the ideal timing calculation unit 22 transmits a state of the target EV from the control panel 201, an operation command transmitted from the control panel 201 to the target EV, a start time when the target EV starts an operation specified by the operation command, Receive.

  Next, the ideal timing calculation unit 22 extracts the ideal operation time from the start time to the ideal timing from the ideal operation time DB 21 based on the state of the target EV and the operation command. And the ideal timing calculation part 22 calculates the total time which totaled the extracted ideal operation time, and calculates the time after total time from a start time as an ideal timing.

  For example, when the predetermined condition is “end of operation command”, the state of the target EV is “stop on the first floor”, and the operation command is “move to the second floor”, the ideal timing calculation unit 22 performs the ideal operation of FIG. 5 seconds (first floor → second floor) are extracted from the time table as the ideal operation time. In this case, the total time is 5 seconds. Then, the ideal timing calculation unit 22 calculates 5 seconds after the start time as the ideal timing.

  Further, when the predetermined condition is “the door is fully open”, the state of the target EV is “stop on the first floor”, and the operation command is “move to the second floor”, the ideal timing calculation unit 22 5 seconds (1st floor → 2nd floor) and 3 seconds (door closed → door open) are extracted from the ideal operation time table as the ideal operation time. In this case, the total time is 8 seconds. Then, the ideal timing calculation unit 22 calculates 8 seconds after the start time as the ideal timing.

  The failure diagnosis unit 3 diagnoses the presence or absence of a failure of the target EV based on the ideal timing and the actual timing. The actual timing is the time when the target EV performs the operation specified by the operation command and actually satisfies the above-described predetermined condition. For each condition, there is a one-to-one correspondence between the ideal timing and the actual timing. The failure diagnosis unit 3 receives actual timing from the control panel 201.

  The failure diagnosis unit 3 diagnoses a failure of the target EV by calculating a time difference (shift in operation timing) between the ideal timing and the actual timing, and comparing the time difference with a predetermined threshold value. Specifically, the failure diagnosis unit 3 diagnoses that the target EV is broken when the time difference is larger than the threshold value. The threshold value can be arbitrarily set, and may be the same or different for each condition for calculating the ideal timing. The diagnosis result by the failure diagnosis unit 3 may be notified by the notification unit 10 described later.
