摘　　要：中国散裂中子源(CSNS)加速器真空控制系统负责真空数据采集、设备监控和闸板阀控制与联锁,是设备运行和故障诊断以及超高真空保持的重要保障。本文介绍了加速器真空需求,基于实验物理及工业控制系统EPICS软件框架的真空控制系统设计与实现,使用横河可编程逻辑控制器PLC控制与联锁设备,摩莎MOXA工控机监测真空状态,EPICS PV数据直接进入声音报警系统和历史数据库系统,为工作人员及时发现和处理问题、进行后续数据分析和机器研究等提供了便捷途径和可靠保障。目前,该系统已完成现场安装和调试,并已正式投入运行。运行结果表明,该系统具有稳定性好、可靠性高、人机交互友好的特点,很好地满足了加速器真空控制系统运行的需要。The accelerator vacuum control system of China Spallation Neutron Source(CSNS) is designed to be responsible for vacuum data acquisition, equipment monitoring and gate valve control and interlock, which is an important guarantee for safe operation, fault diagnosis and ultra-high vacuum. This paper introduces the vacuum requirements of the accelerator, and the vacuum control system design and implementation. Based on the experimental physics and industrial control system(EPICS) software framework, the Yokogawa PLC is used to control and interlock equipment, the MOXA IPC monitors the vacuum status, the EPICS PV data directly enters the BEAST alarm server and the channel archiver, providing convenience and reliable guarantee for the staff to discover and solve problems in time, as well as carry out subsequent data analysis and machine research. At present, the vacuum control system has been installed and debugged on site, and has been put into operation. The results show that the system has the characteristics of high stability, high reliability and friendly operator interface, which satisfies the operational needs.
