Motor speed regulation control system based on AC frequency converter

The invention discloses a speed regulation control system of a motor based on an AC frequency converter, relates to the technical field of motor control, and solves the technical problems in the prior art that no protection device is arranged for the frequency converter, the fault of the frequency converter cannot be monitored and processed in time, the equipment is easily damaged, and the service life of the equipment is shortened. According to the invention, the data interaction unit collects the real-time performance index of the AC frequency converter, and the central analysis unit judges whether the AC frequency converter has a fault based on the collected real-time performance index, and identifies the fault type through constructing a fault diagnosis model. The terminal processing unit matches different solutions according to different fault types and performs early warning; when the alternating-current frequency converter breaks down, the fault type can be rapidly judged and recognized, the fault is p
