  Hereinafter, an elevator maintenance work support system according to an embodiment will be described in detail with reference to the accompanying drawings. In the following description, components having the same functions are denoted by the same reference numerals, and redundant description will be omitted as appropriate.

<First embodiment>
FIG. 1 is a block diagram illustrating a configuration example of an elevator maintenance work support system according to the first embodiment. As shown in FIG. 1, the elevator maintenance work support system according to the present embodiment includes an elevator control device 10 and an invalidation switch 20 provided as elevator equipment. The invalidation switch 20 is connected to the elevator control device 10.

  The elevator control device 10 collects various information related to the operation of the elevator and controls the operation of the elevator. The elevator control device 10 includes an abnormality notification unit 11 and a remote activation unit 12 as functional components related to the present embodiment. These functional components can be realized, for example, by a processor included in a microcomputer in the elevator control device 10 executing a predetermined program, that is, by software. All or some of these functional components may be configured by dedicated hardware such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array). Further, these functional components may be realized by a device different from the elevator control device 10 (outside the elevator control device 10).

  When an abnormality of the elevator is detected, the abnormality notification unit 11 issues a notification (abnormality notification) to a predetermined external notification destination to notify that the abnormality has occurred. The external notification destination is, for example, a terminal in an administrator's office for managing elevator equipment, or a monitor panel of a service information center when a remote maintenance contract for an elevator is concluded.

  The invalidation switch 20 is a switch for switching between valid / invalid of the abnormality report by the abnormality report section 11 in accordance with an operation of a worker performing maintenance work. When the invalidation switch 20 is turned on (CUT side) by the operator performing the maintenance work, the abnormality report by the abnormality report unit 11 is invalidated, and when the switch is turned off (NOR side), the abnormality is abnormal. Alerting is activated. Usually, the operator performing the maintenance work turns the invalidation switch 20 to the ON side before starting the maintenance work to invalidate the abnormality report by the abnormality report section 11, and when the maintenance work is completed, the invalidation switch 20. Is returned to the off side to enable the abnormality alert, but forgetting to return the disable switch 20 may occur.

  In the present embodiment, when the invalidation switch 20 is forgotten to be returned, the abnormality notification by the abnormality notification unit 11 can be activated by a command input from outside the elevator. In order to realize this, the remote control unit 12 is provided in the elevator control device 10.

  The remote activation unit 12 activates an abnormal alarm by the invalid alarm unit 11 according to an invalidation command input from a command source outside the elevator. The command source is, for example, a worker terminal operated by a worker performing maintenance work, a server of a service information center, or the like.

  Next, the operation of the elevator maintenance work support system according to the present embodiment will be described with reference to FIG. FIG. 2 is a flowchart illustrating an operation example of the elevator maintenance work support system according to the present embodiment, and illustrates an example of a processing procedure related to switching between validity / invalidity of abnormality notification.

  The worker performing the maintenance work of the elevator operates the invalidation switch 20 to the ON side when starting the maintenance work. When the invalidation switch 20 is turned on by the operator (step S101: Yes), the abnormality notification by the abnormality notification unit 11 is switched from valid to invalid according to this operation (step S102). If the invalidation switch 20 has not been operated to the ON side (step S101: No), this processing ends as it is.

  Thereafter, it is determined whether or not the invalidation switch 20 has been operated to the off side (step S103). If the invalidation switch 20 has been operated to the off side (step S103: Yes), the process proceeds to step S105, and an abnormality occurs. The abnormal notification by the notification unit 11 is switched from invalid to valid. On the other hand, if the invalidation switch 20 has not been operated to the off side (step S103: No), the remote activation unit 12 monitors whether an activation command has been input from an external command source (step S103). Step S104). If an activation command is input from an external command source (step S104: Yes), the remote activation unit 12 switches the abnormal notification by the abnormal notification unit 11 from invalid to valid (step S105). .

  As described above, in the elevator maintenance work support system according to the present embodiment, the worker who performs the maintenance work forgets to return the disable switch 20 to the off side, and the abnormality report by the abnormality report unit 11 is invalidated. Even when the activation command is input from an external command source, the abnormality report by the abnormality report section 11 is validated according to the activation command. . Therefore, it is possible to effectively prevent the abnormal notification by the abnormal notification unit 11 from being left invalid after the maintenance work is completed.

<Second embodiment>
Next, a second embodiment will be described. This embodiment is obtained by adding a function of determining completion of maintenance work to the first embodiment. Since other functions and operations are the same as those of the above-described first embodiment, only the characteristic portions of the present embodiment will be described below.

  FIG. 3 is a block diagram illustrating a configuration example of an elevator maintenance work support system according to the second embodiment. In the present embodiment, as shown in FIG. 3, a worker terminal 30 operated by a worker performing maintenance work is connected to the elevator control device 10. Further, a completion determination unit 13 is added as a functional component realized in the elevator control device 10.

  The worker terminal 30 is a terminal that is operated by a worker when carrying out maintenance work, is connected to the elevator control device 10 by wire or wirelessly, and communicates with the elevator control device 10. In the present embodiment, when the worker finishes the maintenance work, the worker operates the worker terminal 30 to send a notification to the effect that the maintenance work is finished to the elevator control device 10. In addition, the worker terminal 30 may be a dedicated console device for maintenance work, or may be a smartphone, a tablet terminal, a notebook personal computer, or the like in which application software for maintenance work is installed. In the present embodiment, it is assumed that the worker terminal 30 directly communicates with the elevator control device 10. However, when a remote maintenance contract for the elevator is concluded, the worker terminal 30 is connected to the service information center. It may be configured to communicate indirectly with the elevator control device 10 via a server or the like.

  Completion determination unit 13 performs a maintenance operation when a notification (maintenance work end notification) indicating that maintenance work is to be completed is received from worker terminal 30 in a state where abnormality notification by abnormality notification unit 11 is enabled. It is determined that the work has been completed. That is, upon receiving the maintenance work completion notification from the worker terminal 30, the completion determination unit 13 confirms that the invalidation switch 20 is correctly returned to the off side, and then determines that the maintenance work has been completed. judge. In other words, even if there is a maintenance work completion notification from the worker terminal 30, if the invalidation switch 20 is still operated in the ON state, it is not determined that the maintenance work has been completed. The completion of the maintenance work is recorded as a log, for example. In addition, when the completion of the maintenance work is confirmed, a configuration may be made in which a work report of the maintenance work can be created.

  Next, the operation of the elevator maintenance work support system according to the present embodiment will be described with reference to FIG. FIG. 4 is a flowchart illustrating an operation example of the elevator maintenance work support system according to the present embodiment, and illustrates an example of a processing procedure performed by the completion determination unit 13. The process for switching the validity / invalidity of the abnormal alert is the same as that in the first embodiment (see FIG. 2), and therefore the description is omitted.

  Upon receiving the maintenance work end notification from the worker terminal 30 (step S201: Yes), the completion determination unit 13 checks whether the abnormality reporting by the abnormality reporting unit 11 is enabled (step S202). Then, if the abnormality notification is valid (step S202: Yes), it is determined that the maintenance work has been completed (step S203). On the other hand, when the maintenance work end notification has not been received from the worker terminal 30 (step S201: No), or when the abnormality notification by the abnormality notification unit 11 has been invalidated (step S202: No), the maintenance is performed. The process ends without determining the completion of the operation.

  As described above, the elevator maintenance work support system according to the present embodiment is provided under the condition that the invalidation switch 20 is returned to the off side and the abnormality reporting by the abnormality reporting unit 11 is enabled. When a maintenance work completion notification is received from the worker terminal 30, it is determined that the maintenance work has been completed. Therefore, it is possible to more effectively prevent the abnormal alarm report by the abnormal alarm unit 11 from being left invalid after the maintenance work.

<Third embodiment>
Next, a third embodiment will be described. The present embodiment has a function of validating an abnormal alarm by the abnormal alarm unit 11 in response to an activation command from an external command source, and performing a maintenance operation in response to a maintenance operation end notification from the worker terminal 30. The point of having the function of determining completion is the same as in the above-described second embodiment, but the fact that the abnormality reporting by the abnormality reporting unit 11 is enabled is not a condition for determining that the maintenance work has been completed. . Instead, on the condition that it is determined that the maintenance work has been completed, the input of an activation command from an external command source is permitted. Since other functions and operations are the same as those of the above-described second embodiment, only the characteristic portions of the present embodiment will be described below.

  FIG. 5 is a block diagram illustrating a configuration example of an elevator maintenance work support system according to the third embodiment. In the present embodiment, as shown in FIG. 5, an input determination unit 14 is added as a functional component realized in the elevator control device 10.

  The completion determination unit 13 according to the present embodiment, even when the abnormal notification by the abnormal notification unit 11 is invalid, receives the maintenance work completion notification from the worker terminal 30 and completes the maintenance work. It is determined that it has been performed.

  The input determination unit 14 determines whether to input an activation command from an external command source. The input determination unit 14 in the present embodiment permits the input of the activation command on condition that the completion determination unit 13 receives the maintenance work completion notification from the worker terminal 30 and determines that the maintenance work is completed. That is, before the completion determination unit 13 determines that the maintenance work is completed, the input of the activation command from the external command source is not accepted, and the completion determination unit 13 determines that the maintenance work is completed. Thereafter, an input of an activation command from an external command source is accepted by the input determination unit 14 and passed to the remote activation unit 12. In response to the activation command, the remote activation unit 12 switches the abnormal notification by the abnormal notification unit 11 from invalid to valid.

  Next, an operation of the elevator maintenance work support system according to the present embodiment will be described with reference to FIG. FIG. 6 is a flowchart illustrating an operation example of the elevator maintenance work support system according to the present embodiment, and illustrates an example of a processing procedure related to switching between validity / invalidity of abnormality notification. Note that the processing from step S301 to step S303 in FIG. 6 is the same as the above-described first embodiment (the processing from step S101 to step S103 in FIG. 2), and a description thereof will be omitted.

  In this embodiment, when the invalidation switch 20 is not operated to the off side (step S303: No), the input determination unit 14 monitors whether or not an activation command is input from an external command source (step S303). Step S304). Then, when an activation command is input from an external command source (step S304: Yes), the input determination unit 14 checks whether or not the completion determination unit 13 determines that the maintenance work has been completed (step S304). Step S305).

  Here, when the completion determination unit 13 does not determine that the maintenance work has been completed (step S305: No), the input determination unit 14 returns to step S304 without accepting the input of the activation command, and returns to step S304. Continue monitoring input. On the other hand, if the completion determination unit 13 determines that the maintenance work has been completed (step S305: Yes), the input of the activation command is accepted and passed to the remote activation unit 12. Then, in response to the activation command, the remote activation unit 12 switches the abnormal notification by the abnormal notification unit 11 from invalid to valid (step S306).

  As described above, the elevator maintenance work support system according to the present embodiment transmits an external command on the condition that the maintenance work is notified from the worker terminal 30 and that the maintenance work is completed. The abnormality reporting by the abnormality reporting unit 11 is validated according to the activation command input from the beginning. Therefore, it is possible to more effectively prevent the abnormal alarm report by the abnormal alarm unit 11 from being left invalid after the maintenance work is completed.

<Fourth embodiment>
Next, a fourth embodiment will be described. In the present embodiment, when an activation command is input from an external command source, a worker who performs maintenance work accepts the activation of the abnormality report, and This is to enable the abnormality report by the abnormality report section 11.

Step S404). Then, when an activation command is input from an external command source (step S404: Yes), the consent confirmation unit 15 sends the maintenance work completion notification to the elevator control device 10 to the worker terminal 30. An inquiry as to whether or not to accept the activation of the abnormal notification is given (step S405).

  Here, if there is no response from the worker terminal 30 to the effect that the activation of the abnormal notification is accepted (step S406: No), the acceptance confirmation unit 15 discards the input activation command and returns to step S404. , Continue to monitor the input of the enable command. On the other hand, if there is a response from the worker terminal 30 to the effect that the activation of the abnormal notification is accepted (step S406: Yes), the input activation command is passed to the remote activation unit 12. Then, in response to the activation command, the remote activation unit 12 switches the abnormal notification by the abnormal notification unit 11 from invalid to valid (step S407).

  As described above, in the elevator maintenance work support system according to the present embodiment, when an activation command is input from an external command source, the worker performing the maintenance work approves the activation of the abnormal notification.
