In view of the actual demand of fault detection of rollers in coal mine belt conveyor,a new method of idler condition monitoring based on multi-sensor fusion is proposed.By placing vibration,acoustic emission,temperature and strain sensor arrays on conveyor rollers,a monitoring data set reflecting the health status of rollers is established.Multi-sensor information fusion technology is used to analyze the fault characteristics of idlers from the response angles of vibration,acoustic emission,temperature and other physical fields,and to realize the high-precision diagnosis and early warning of idler faults.The research can provide reliable technical support for the safe operation of coal mine conveying system.
