Coal mine belt conveying motor temperature monitoring method and system

The invention belongs to the field of safety management of coal mine belt conveying motors, and relates to a temperature monitoring method and system for a coal mine belt conveying motor. According to the method, firstly, temperature anomaly evaluation indexes of a motor body, a motor shaft and a bearing are comprehensively considered, a motor temperature risk coefficient is comprehensively and scientifically analyzed in combination with a heat dissipation anomaly evaluation coefficient of a motor, secondly, a temperature risk coefficient of a conveyor is analyzed on the basis of internal and external risk factors of the conveyor, and then temperature monitoring is performed on a coupler. And the operation temperature and the related temperature rise condition of the coupler are known in detail to analyze the temperature risk coefficient of the coupler. Based on the temperature risk coefficients of the motor, the conveyor and the coupler, comprehensive monitoring of the target coal mine belt conveying motor i
