摘要
用触摸屏和PLC(可编程逻辑控制器)实现控制是现代工业控制中的一种新方法。文中基于三菱F940GOT-LWD-C型触摸屏和FX0S-30MR型PLC,提出了4路抢答器控制系统。描述了触摸屏的工作原理及特点,阐述了控制系统硬件与软件设计方案,实现了对四路抢答器的监控。系统软件设计包括触摸屏端的画面运行系统的设计和基于顺序功能图的控制程序设计。实际应用表明,该系统具有运行稳定、可靠性高、实用性强等特点。
It is a new control method based on touching screen and PLC in the modern industrial control system, and their applications are more and more widely. Based on the Mitsubishi F940GOT-LWD-C touching screen and FXOS-30MR PLC, a four-way vying answer machine control system is proposed. This paper describes the working theory and characters of touching screen, and expatiates hardware and software designing scheme of the system, and implements the monitoring and controlling to the four-way vying answer machine. The software design includes graphic running system of touching screen and control program based on sequential function chart. The application indieates that the system has some advantages of running stably, high reliability and better practicability.
