可编程序控制器在变频调速顺序给矿控制中的应用

The Application of the Programmable Controller in the Sequential Feed Control by Frequency Conversion Speed Regulation

本文介绍了可编程序控制器轮换控制贮矿仓给矿机的主电路、输入和输出点参数及控制程序的编制框图。生产应用表明，它结构简单，编程方便，在执行逻辑、计数、计时、顺序控制时性能优越，值得借鉴。

Abstract The paper describes the main circuit input and output point parameters of the sequential control of ore bin feeders by the programmble controller and the block diagram of the control program. Its application in the production has shown that it is simple in structure and convenient in programming and has excellent performances in executing logic .counting,timing and sequential control,so it is worth making use of.
