基于PLC的工程轮胎翻新设备控制系统设计

摘要

To achieve semi-automatic control of the tire retreading equipment without changing the original mechanical components, a new control system is designed using PLC, touch screen as well as position sensors etc. The control ladder diagram and the human-machine interface are designed by CX-Programmer and CX-Designer respectively. Serial communication implemented through RS232 between PLC and touch screen, user-friendly interface created on touch screen, control and management of the system are combined, which improves stability of product quality and efficiency of labors as well.%在原有手动机械系统的基础上,利用可编程逻辑控制器(PLC)与触摸屏,组成主控单元,配合使用光栅传感器等,实现了工程轮胎翻新设备的自动控制.梯形图程序和触摸屏人机界面分别通过Omron公司的软件CX - Programmer和CX - Designer设计实现.PLC通过RS232接口与触摸屏进行串行通讯,在触摸屏上设计友好人机界面,实现控制与管理的结合,从而提高了产品质量的稳定性以及工人的工作效率.
