Abstract: 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.
