Problems solved by technology

[0004] However, this switch is manually operated by the operator, so there may be cases where the switch is forgotten to be returned after the maintenance work is completed.
In addition, when the abnormality report remains invalidated due to forgetting to return the switch, it is possible that the abnormality report will not be performed even if an abnormality occurs during normal operation of the elevator, resulting in a problem.

no. 1 Embodiment approach

[0022] First, refer to figure 1 as well as figure 2 The configuration of the elevator maintenance work support system according to the first embodiment will be described. figure 1 It is a block diagram showing a configuration example of an elevator maintenance support system according to the first embodiment, figure 2 It is a perspective view of a housing provided with an invalidation switch.

[0023] Such as figure 1 As shown, the elevator maintenance work support system according to this embodiment includes an elevator control device 10 installed as elevator equipment, a nullification switch 20, a cover close detector 30, and an elevator maintenance work operator to operate. Operator terminal 50 .

[0024] The elevator control device 10 collects various information related to the operation of the elevator and controls the operation of the elevator. This elevator control device 10 includes an abnormality reporting unit 11 , a notification unit 12 , and a completion det...

no. 2 Embodiment approach

[0042] Next, a second embodiment will be described. An operator performing maintenance work may close the cover 101 of the housing 100 to start the maintenance work after turning the invalidation switch 20 to the ON side to disable the abnormality report of the abnormality reporting unit 11 . At this time, although the notification operation of the notification unit 12 is performed, it is assumed that the operator intends to return the invalidation switch 20 to the OFF side at the end of the maintenance work and ignore the notification operation. In this case, even if forgetting to return the disabling switch 20 occurs at the end of the maintenance work, it is impossible for the operator to notice the forgetting to return the disabling switch 20 .

[0043] Therefore, in the present embodiment, the elapsed time is measured from when the cover 101 of the housing 100 is closed when the abnormality report of the abnormality reporting unit 11 is disabled, and when the elapsed time ...

no. 3 Embodiment approach

[0052] Next, a third embodiment will be described. In this embodiment, when forgetting to return the invalidation switch 20, the abnormality report of the abnormality reporting part 11 can be validated by the command input from the elevator exterior. However, in order to prevent accidental activation of the abnormality report during maintenance work, the abnormality report is disabled and the cover 101 of the housing 100 is detected to be closed by the cover closing detector 30 as a condition. input the command. In addition, other functions and operations are the same as those of the above-mentioned first embodiment, so only the characteristic parts of this embodiment will be described below.

[0053] Figure 7 It is a block diagram showing a configuration example of an elevator maintenance work support system according to a third embodiment. In this embodiment, if Figure 7 As shown, a remote validating unit 15 is added as a functional component realized in the elevator c...

Abstract

The embodiment of the invention provides a maintenance operation support system of an elevator, which can effectively prevent an abnormal report from being kept in an invalid state after maintenance operation is finished. The maintenance work support system according to an embodiment is provided with an abnormality reporting unit, a switch, a detection means, and a notification unit. The abnormityreporting unit is used for reporting the abnormity when the abnormity of the elevator is detected. The switch is provided inside a housing having a cover that can be opened and closed by an operatorperforming maintenance work, and the validity / invalidity of the abnormality report is switched in accordance with the operation of the operator. The detection unit detects a closed state of the cover.The notification unit performs a notification operation when it is detected that the cover is closed in a state where the abnormality report is set to be invalid.

Description

[0001] This application is based on Japanese patent application 2018-130110 (filing date: July 9, 2018), and enjoys the priority of this application. This application incorporates the entire content of this application by reference. technical field [0002] Embodiments of the present invention relate to an elevator maintenance work support system. Background technique [0003] Elevators are extremely important equipment for ensuring their safety, and maintenance work is regularly performed to ensure their safety. The maintenance work of an elevator includes an operation of intentionally bringing the elevator into a state in which an abnormality is detected in a state where an abnormality has not actually occurred, and performing operation confirmation. Generally, an elevator is provided with a function of reporting an abnormality when an abnormality is detected, but when the elevator is intentionally brought into a state where an abnormality is detected during maintenance w...
