摘　　要：以矿用EBZ200C型掘进机为研究对象,结合工程实践情况对自动截割控制系统进行了设计。系统可以分为下位机部分和上位机部分,前者主要是对掘进机截割头的位置及工作电流进行检测,后者主要是运行系统中内置的程序,两者结合可以实现掘进机的综合控制。以上2个部分的控制器分别为S7-200型PLC控制器和PP480型智能控制面板。系统基于PID技术实现闭环控制,可以保障控制过程的精度和稳定性。将控制系统应用到工程实践中,对其应用效果进行现场测试发现,各项功能都达到了预期效果,整体运行良好。Taking the mining EBZ200C roadheader as the research object,the automatic cutting control system was designed according to the engineering practice.The system can be divided into a lower computer part and an upper computer part.The former mainly detects the position and working current of the cutting head of the roadheader,and the latter mainly operates the program built in the system.The combination of the two can realize the integration of the roadheader control.The controllers of the above two parts are S7-200 PLC controller and PP480 intelligent control panel respectively.The system realizes closed-loop control based on PID technology,which can guarantee the accuracy and stability of the control process.The control system was applied to engineering practice,and its application effect was tested on site.It was found that all functions have reached the expected effect,and the overall operation is good.
