Abstract

A motor operation state monitoring and fault detecting system is composed of a voltage transformer, a current transformer, an optical-electricity encoder, acceleration sensors, temperature sensors, a microprocessor, a display unit, a sound-light alarm unit and a wireless communication module. The voltage transformer and the current transformer are installed on a power supply circuit of a motor. The optical-electricity encoder is installed on an output rotating shaft of the motor. The acceleration sensors are installed at the tail and the left side face of the motor and arranged above the motor. The temperature sensors are installed at the two ends and the middle end of the motor. The microprocessor receives signals output by the voltage transformer, the current transformer, the acceleration transformers and the temperature sensors, and controls the sound-light alarm unit to give an alarm and send operation parameters of the motor to a central control unit through the wireless communication module. The motor operation state monitoring and fault detecting system has the advantages that the signals can be collected, processed and analyzed without control of a PC, the operation states of the motor can be monitored in real time, the motor operation state monitoring and fault detecting system has the function of diagnosing the motor fault, the sound-light alarm can be given when the motor breaks down, and the accident rate is reduced.
