[Abstract]:At present, the coal mining machine control system, which is widely used with PLC as the core, is lack of autonomy and flexibility in the real-time processing of a lot of data and the realization of complex control algorithm. This paper studies the electric control system of electric traction shearer based on DSP. With the help of DSP's high speed, high precision calculation ability and abundant in-chip resources, a series of advanced control algorithms can be realized to monitor the fault of shearer system on line. Intelligent control and coal-rock interface recognition are of great significance. The control requirements of electric haulage shearer and the automation and intelligent technology of adapting to different geological environment and remote control are deeply studied. The solution of electric control system of electric traction shearer based on DSP is put forward. This scheme takes DSP as the main control module, realizes the external IOs with the help of the rich peripheral equipment of DSP, collects the analog quantity and communicates with the peripheral equipment, accomplishes the basic action control and the state monitoring information display function of the electric traction shearer. In addition, the remote control of electric traction shearer is realized by remote control module. The paper designs the DSP controller digital interface module, completes the external interface design of the electric traction shearer control part, further completes the frequency converter control mode design and the software realization method design. Finally, the basic control function of electric traction shearer is realized, the state data in the working process of electric traction shearer is monitored in real time, and the error correction of ADC module improves the accuracy of monitoring signal and ensures the safe and stable operation of shearer. Then the communication between the DSP controller and the touch screen is solved, the state data of the electric traction shearer is displayed to the touch screen in real time, and the CAN communication interface is designed, which makes use of the characteristics of high speed and long transmission distance of the CAN bus. The communication between remote control computer and electric control system of electric traction shearer based on DSP is realized. The electric control system of electric traction shearer is verified by the experimental platform. The system can realize the monitoring and control function of electric traction shearer, and the touch screen can display the state information of shearer in real time. In addition, the remote control computer can not only read the state information of shearer in real time, but also accurately control the shearer to perform the corresponding action.
