Design of Control System of Shearer Based on EPEC Controller
-
摘要: 针对基于PLC的采煤机控制系统存在防护等级低、抗振动能力差、结构布置复杂等问题,提出了一种基于EPEC控制器的采煤机控制系统的设计方案。该系统采用带CAN总线的EPEC控制器将现场实时数据打包成PDO报文传输至CAN总线,再由CAN232MB和CAN485MB模块分别将报文传输给显示器和上位机,从而实现对采煤机运行状态的实时监测。实际应用表明,该系统提高了采煤机控制系统的抗干扰性和可靠性,降低了采煤机控制系统的故障率。Abstract: 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.
