Fault recognition system and method for escalator or moving walkway

Abstract

The invention discloses a fault recognition system and method for an escalator or a moving walkway. The fault recognition system comprises a pair of intelligent guide rails symmetrically disposed on two sides of the escalator correspondingly, an intelligent step corresponding to the intelligent guide rails, a step roller or a step chain roller disposed above the intelligent guide rails and step fault monitoring devices correspondingly disposed on the intelligent guide rails on both side, wherein the step fault monitoring devices each comprise a side surface sensor for measuring guide rail vibration or step roller pressure and a first signal processing module for analyzing or uploading a measured signal. The fault recognition system and method can recognize and position faults such as steproller wear and cracking, rail joint opening and loosening and guide rail foreign matter, and facilitate the maintenance of the escalator or the moving walkway.

Description

technical field [0001] The present invention relates to a technology in the field of public transportation facilities, specifically a fault identification system and method for escalators or moving walks, mainly aimed at the wear and tear of step rollers, cracks, foreign objects on guide rails and joints of guide rails in the field of escalators or moving walks Identification of faults such as loosening. Background technique [0002] As the key moving parts of the escalator, the steps and their guide rails have an important impact on the service life and safety management of the escalator. Due to the complex operating environment of the escalator, loosening of the splicing joints of the step guide rails, excessive gaps, and foreign matter absorbed by the guide rails will cause the steps to vibrate abnormally, which will cause the step rollers to wear and crack, reducing the service life of the step rollers and the use of the escalator comfort. At the same time, in the norm...

AI Technical Summary

Problems solved by technology

Due to the complex operating environment of the escalator, loosening of the splicing joints of the step guide rails, excessive gaps, and foreign matter absorbed by the guide rails will cause the steps to vibrate abnormally, which will cause the step rollers to wear and crack, reducing the service life of the step rollers and the use of the escalator comfort

At the same time, in the normal maintenance of escalators, due to the limited space of the truss structure and the inconspicuous perception of vibration and noise, it is impossible to effectively identify foreign objects on the guide rail, wear and tear of the step rollers, and cracks. Therefore, it is necessary to monitor the status of the steps and their guide rails. , to identify faults in time and reduce the risk of escalator operation

At present, only a few escalator manufacturers have developed monitoring technology for roller wear and cracking, but the existing technology needs to arrange optocoupler transmitter and receiver equipment on each guide rail, which is costly and is easily blocked by foreign objects on the guide rail. Lubricating oil pollution and other effects, the monitoring effect is limited
