Problems solved by technology

However, if there are relatively loud external noises such as the sound of passengers walking, BGM played in facilities with passenger conveyors, and guide announcements, etc., the impact of the external noise on the statistical feature value will appear.
Therefore, it may be difficult to accurately diagnose the abnormality of the passenger conveyor

Embodiment Construction

[0013] Next, specific embodiments of the present invention will be described with reference to the drawings. In addition, in the following embodiments, an escalator in which a plurality of treads move diagonally across upper and lower floors is exemplified as an example of a passenger conveyor to be diagnosed. However, it goes without saying that the present invention is also effectively applicable to a case where a moving walkway that is connected with a plurality of pedals and moves in the horizontal direction is used as the object of diagnosis.

[0014] Escalators as objects of diagnosis, such as figure 1 As shown, it is supported by a truss 1 erected between the upper and lower floors. The driving device 2 of the escalator is provided on the upper side inside the truss 1 . The drive device 2 drives the sprocket 4 via the drive chain 3 . The driven sprocket 5 paired with the driving sprocket 4 is provided on the lower stage side inside the truss 1 . The pedal chain 6 is...

Abstract

In a passenger conveyer abnormality diagnosis system, sound data of escalator operating sound of a plurality of revolutions is collected by a moving sound collector provided for an inspection step and then processed into a data set for diagnosis with an accidental external noise component removed. The data set for diagnosis sent from a data transceiver through a communication network to a remote monitoring apparatus installed at a remote-located monitoring center. The remote monitoring apparatus diagnose the presence of abnormalities of the escalator based on the data set for diagnosis.

Description

technical field [0001] The present invention relates to an abnormality diagnosis system for diagnosing abnormalities of passenger conveyors such as escalators and moving walkways. Background technique [0002] Passenger conveyors such as escalators and moving walkways convey passengers riding on the steps by circularly moving a plurality of steps connected in a loop along guide rails arranged inside the truss. Once this kind of passenger conveyor breaks down, it often takes a lot of time to restore it. Therefore, once it breaks down, it will cause great trouble to the user. Therefore, it is hoped that the abnormality can be detected early at the stage when any abnormality occurs before the failure occurs, so that the abnormality can be eliminated through maintenance to avoid failure. [0003] Against such a background, in Patent Document 1, a diagnostic device incorporating an acceleration sensor, a microphone, and the like is provided on a pedal that circulates. With such...
