Embodiment Construction

[0019] Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following embodiments, an escalator in which a plurality of steps moves obliquely across upper and lower floors is exemplified as an example of the passenger conveyance device. However, of course, the present invention can also be effectively applied when a moving walk in which a plurality of steps (steps) continuously moves in the horizontal direction is used as a diagnostic object.

[0020] (first embodiment)

[0021] exist figure 1 In the abnormality diagnosis system according to the first embodiment of the present invention shown, the escalator to be diagnosed is supported by the truss 3 connected to the upper beam 1 and the lower beam 2 and erected between the upper and lower floors. In the truss 3 on the side of the upper beam 1, a driving device 4 for the escalator is provided. The driving device 4 is controlled by the cont...

Abstract

The invention provides an abnormality diagnostic system for passenger conveyor, comprising a monitor (20) with a CPU (21) causing a sound collector (17) to collect the running sound of an automatic staircase and store the sound in an internal storage (22) when estimating that interference sound other than the running sound of the automatic staircase is below the reference level during the start, stop, automatic running or low-speed running of the automatic staircase.

Description

technical field [0001] The present invention relates to an abnormality diagnosis system for diagnosing abnormalities of passenger conveying devices such as escalators and moving sidewalks. Background technique [0002] Passenger conveying devices such as escalators and moving sidewalks are constructed in such a way that a plurality of steps linked by chains are driven by a motor to move circularly along the guide rails arranged inside the truss, thereby moving passengers on the steps from one side to the other. The landing port on the other side is transported to the landing port on the other side. In the passenger conveying device constructed in this way, abnormalities such as friction and contact resistance of movable parts may occur due to wear and tear of articles caused by long-term operation, aging deterioration of the installation and adjustment state, contamination of foreign matter, mischief of passengers, and the like. Such anomalies often manifest as voices. [...
