Design of interlock system for C-ADS injector Ⅰ

摘要: 联锁保护系统是加速器驱动次临界系统(ADS)先导专项(C-ADS)核心系统之一,用于对加速器控制及人身和设备保护。为此设计搭建了基于可编程逻辑控制器(PLC)和PROFINET协议的联锁控制系统,对加速器各个关键部件的信号进行采集和控制。为满足加速器对可靠性的严格要求,该联锁系统选用最新型的PLC和I/O模块,并采用高可靠性容错和冗余技术的硬件设计。本文还对该联锁系统的冗余状态和非冗余状态做了可靠性分析对比。基于该系统的实验物理和工业控制系统(EPICS)的控制接口也已成功开发,并在线应用。

Abstract: An interlock control system based on a new redundant Programmable Logic Controller (PLC) and PROFINET protocol is developed as one of the key systems in China Accelerator Driven Sub-critical System (C-ADS) injector Ⅰ for machine control and personnel protection. Signals from critical accelerator components are sent to this system for safety protection. Fault-tolerance and redundancy for high reliability are considered through the whole design, and reliability analysis of both redundant and non-redundant systems is done to meet the strict requirement. A control interface of Experimental Physics and Industrial Control System (EPICS) is developed and successfully used online.
