This paper expounds the research status of mine-used motor protection and the monitoring system. According to the mine environmental characteristics, the mine-used motor protector and the optical fiber monitoring system are designed. This system can realize themotor signal acquisition and processing based on MCU, so as to achieve the fault diagnosis and protection of the motor： In addition, it adopts optical fiber transmission to realize the manmachine interactive control and uses serial communication on PC to realize the real-time monitoring of motor operation status. The analysis shows that the fiber monitoring system can protect the motor effectively under harsh environment and strong electromagnetic interference.
