Abstract

The embodiment of the invention provides a cascaded fault monitoring method, device and system. The cascaded fault monitoring method comprises the following steps: obtaining the position information of each sampling time of each cascade of a to-be-monitored elevator within the preset time interval and a plurality of acoustic emission signals; for each cascade, carrying out envelope detection, spreading time difference correction and superposition treatment on the sampling time sequence of each acoustic emission signal to obtain a plurality of processed acoustic emission signals; and accordingto the value and position information of the processed acoustic emission signal of each cascade within each sampling time, determining whether the to-be-monitored elevator has fault within the presettime interval. The cascaded fault monitoring method can timely find hidden danger of the cascaded fault to improve the user's experience.

Description

technical field [0001] The embodiments of the present invention relate to the field of public transportation, and in particular to a cascade failure monitoring method, device and system. Background technique [0002] With the progress of society, escalators have been widely used in shopping malls and urban rail transit stations. Escalators are composed of ladder road system, main transmission system, ladder road tensioning device, etc. Among them, the ladder is composed of steps and step guide rails. Among them The steps are the most numerous parts of the escalator and are the moving parts that carry passengers, so it is very important to find out the faults of the steps in time. [0003] In the prior art, by regularly closing the escalator, the method of manual inspection is used to troubleshoot the step faults. Among them, the common faults of the steps include: step deviation, step hitting the comb plate, step hitting the skirt plate, step buckle fatigue fracture, etc. ....
