SFC编程方法在煤矿带式输送机监控系统中的应用

摘要

In view of problems of long program cycle, poor readability and difficult programm maintenance because of using empirical method to design PLC program of monitoring and control system of coal mine belt conveyor, the paper proposed a scheme of using SFC programming method to design ladder of monitoring and control system of coal mine belt conveyor. The practice showed that the scheme has characteristics of convenient design, good readatility, easy maintenance and so on.%针对煤矿带式输送机监控系统中的PLC程序因采用经验法设计而存在编写周期长、可读性差、程序维护困难等问题,提出了一种采用SFC编程方法设计煤矿带式输送机监控系统梯形图的方案.实践表明,该方案具有设计方便、可读性好、维护简单等特点.
