摘要
作为一种新型控制系统,PLC(可编程逻辑控制器)可以广泛地应用在ZJ19卷接机组靠拢轮升降控制中。通过实时监测ZJ19卷接机组靠拢轮升降的工作流程和分析原逻辑阀控制存在的弊端,本文重点介绍了用PLC及电磁气阀替代原逻辑阀电路和程序的改造方法。
As a new type of control system,PLC(Programmable Logic Controller)can be widely used in the ZJ19 coil?ing unit lifting wheel lifting control.Through real-time monitoring of the working process of ZJ19 coiling unit lifting wheel lifting and analyzing the disadvantages of the original logic valve control,this paper focused on the transforma?tion method of replacing the original logic valve circuit and program with PLC and electromagnetic valve.
