摘要
本文介绍一种设计安全联锁系统的新方法。它的基本思想是用可编程控制器(PROGRAMMABLECONTROLLER——PC或PLC)组成分布式系统,替代过去的继电器和专用逻辑,以改善系统的可靠性、可维护性和可扩充性,并节省人力和资金。一台多媒体IBM-PC兼容机用作上位机,监控整个系统。该上位机还配备TV系统以显示BEPC的运行消息。
A new interlock system for BEPC (Beijing Electron Positron Collider ) has been developed in order to improve the reliability of the personal safety and the subsystem's interlocks . Another role of the system is to update the BEPC TV status screen once every 6 seconds. The hardware for the new interlock system is based on industrial Programmable logic controllers (PLC). By means of the PC_links, the interlock system is composed as a distributed control system. One inexpensive multimedia IBM/486 PC is used as the host computer of the PLCs. The application programs dedicated for the system is written in visual C++ language under Chinese MS Windows. In case there is a failure in a subsystem, the message is displayed visually, supplemented by a voice message, which causes the operators to pay attention.
