对于现阶段我国的煤矿上主要应用了PLC,即可编程序控制器,此控制器以其功能的完善和强大性,还有较高的可靠性,在煤矿的安全性被越来越受到重视的今天,该系统得到广泛的应用。并且PLC系统的自动控制能力较为强大,大大提高了工作的效率。首先介绍了PLC集控系统的结构,然后分析了PLC系统的工作原理,最后联系该系统的结构以及运行原理来介绍该系统在煤矿带式输送机系统中的应用。 At present, China’s coal mines mainly use PLC, that is, programmable logic controller. This controller is more and more important in the safety of coal mines for its perfect and powerful functions and high reliability Today, the system is widely used. And PLC system is more powerful automatic control, greatly improving the efficiency of the work. Firstly, the structure of PLC control system is introduced. Then the working principle of PLC system is analyzed. Finally, the structure and operation principle of the system are introduced to introduce the application of the system in the coal belt conveyor system.
