电动机运行状态在线智能监测系统研究
Research on on-line intelligent monitoring system of motor running state
摘要
Abstract
Motor is an indispensable tool in machining.The various faults often take place in the motor operation.In order to en-sure the safe running of the motor,it is particularly important for on-line monitoring of the motor running state.Three-phase asyn-chronous motor was regarded as the research object.The important parameters of the motor running(vibration,sound,speed and temperature)were obtained by the sensor acquisition.The motor running features were extracted by the time-frequency analysis and energy analysis,and those features constituted feature vectors.The state recognition model was built according to BP neural network training method.The motor running state was evaluated according to BP neural network pattern recognition method.The visualization monitoring system was constructed by using LabVIEW software.The motor running parameters and the states were re-al-time displayed in the visual interface,and the on-line intelligent monitoring was completed.关键词
