Servo motors are an important part of the antenna transmission chain in shipbased measurement and control antenna.Because control systems are away from the antenna, it is not easy running realtime monitoring of the servo motor. To solve the problem of realtime monitoring during multiple antenna servo motor running, we studied the data collection and fault diagnosis technology of servo motor, From hardware design, software and database design, network model is proposed based on three aspects of the design troubleshooting servo motor condition monitoring system. So that we can monitor the realtime transmission chain online motor running,and backup servo motor performance measurements can be detected.Practical application shows that this system can timely response servo motor working condition, and to achieve the effect of the remote testing and diagnosis.
