Design and Implementation of Electric Drive Shearer Control System

In view of the problems of poor flexibility and insufficient data processing ability in the control system of electric traction shearer, an electric traction shearer electromechanical control system based on DSP+CPLD is designed. The hardware and software design scheme of the electric drive shearer control system with TMS320C2812 DSP chip and EMP240T100C5 CPLD chip as the central control unit is analyzed. The central control unit periodically collects the analog digital signals of shearer body, and interacts with the master and slave frequency converter, touch screen, remote control computer, etc. in the CAN bus communication mode, to complete the shearer control, local display and remote control. It is shown through the test analysis that the designed and realized electric drive shearer control system meets the design requirements, improves the intelligence level of the shearer, and improves the flexibility and data processing capacity of the control system.
