【Abstract】 Several digital methods of monitoring longitudinal rip of conveyor belts are analyzed,and the vibration detection scheme is proposed.In the vibration scheme,vibration exciting signals are add to one side of the belt,and the wireless vibration signal collection system is used to collect vibration signals on the other side of the belt.After noise signals being removed by correlation analysis,the wavelet analysis is used to detect odd points,so as to accurately judge the moments when faults happen.In addition,the systematic structure of the vibration detection scheme is introduced,in which,the wireless data collection device is applied and MatLab is used to analyze and process data,as well as the digital vibration monitoring scheme is applied,thus the fault detection ratio of belt longitudinal rip effectively improves.更多还原
