Abstract: In view of status that existing control system of shearer is difficult to meet demand of automation control of working face in terms of real-time data collection and processing, remote monitoring and integrated intelligent control algorithm, a control system of electric traction shearer oriented automatic working face was designed. The system adopts double DSP architecture, and uses powerful data processing ability and rich peripherals of DSP to complete data collection and calculation of working condition of shearer, and real-time communication with peripheral equipments. The system realizes functions of automatic cutting control of shearer, coal mining technological change and remote monitoring, which can provide technical support for automation mining of shearer.
