基于千兆以太网的CSNS RCS射频分布式控制系统架构

摘要

中国散裂中子源(China Spallation Neutron Source,CSNS)快循环同步加速器的射频系统的远程控制系统采用基于千兆以太网的分布式体系结构,其软件架构使用国际加速器界广泛使用的开源软件工具EPICS(Experimental and Industrial Control System)进行开发.系统主要由CPCI低电平控制器、高功率四极管放大器和偏流源机器状态监控网络、联锁保护系统、中控中转服务器和人机交互界面组成.论文主要介绍了该系统的基本功能和拓扑结构,以及各个组成部分软硬件的设计和实现.%The rapid cycling synchrotron (RCS) RF control system of China Spallation Neutron Source (CSNS) is a distributed control system (DCS)based on Gigabit Ethernet used stand EPICS CA protocol.The system consists of five parts:low level RF(LLRF) controller based on CPCI bus,monitoring and control network of high power tetrode amplifier and bias supply,interlock protection system,mid server to center control room and operator interfaces (OPIs).This paper mainly presents the architecture of the CSNS RCS RF control system,and show the hardware and software implementation at the various components.
