Design of Control System of Shearer Based on EPEC Controller

  • In view of problems of low protection level, bad anti-vibration ability and complex structure existed in control system of shearer based on PLC, the paper proposed a design scheme of control system of shearer based on EPEC controller. The system packs real-time data to PDO messages and transfers the messages to CAN bus by use of EPEC controller with CAN bus, then CAN232MB module and CAN485MB module transfer the messages to display and upper computer respectively, so as to realize real-time monitoring for running state of shearer. The actual application showed that the system improves anti-interference ability and reliability and reduces fault rate of control system of shearer.
