摘要
可编程序控制器(PLC)是综合了计算机技术和自动控制技术发展而来的一种新型工业控制装置。触摸屏是一种新型的可接收触头等输入讯号的感应式液晶显示装置。利用可编程控制器和触摸屏改造、设计了一套真空镀膜设备的自动控制系统,实现了真空镀膜设备的自动控制。根据真空镀膜设备的控制要求,详细阐述了整个系统软硬件设计的过程。
PLC programmable logic controller(PLC) is a new kind of industrial control device which integrates computer technology and automatic control technology. Touch screen is a new type of inductive liquid crystal display device which can receive first-class input signals. In this paper,an automatic control system of vacuum coating equipment controlled by PLC and touch screen is designed to realize the automatic control of vacuum coating equipment. According to the control requirements of vacuum coating equipment, the design process of software and hardware of the whole system is described in detail.
