摘　　要：Background Vacuum control and interlock system plays an important role in maintaining the vacuum condition for the normal operation of SESRI heavy ion accelerator.Vacuum failure of beam line at any position will cause beam loss,experimental failure,and even serious consequences of accelerator shutdown.Methods This control system is designed and realized based on EPICS structure and PLC controller to realize the control and interlocking function of all kinds of vacuum equipment and ensure the operation and safety of the equipment.PLC level interlock and contact-based hardware interlock methods are used to realize both stability andflexibility.Results After a period of test running and actual operation,it is proved that this vacuum control and interlock system shows good stability,reliability andflexibility.Conclusion The vacuum control and interlock system in this paper realizes the design requirements of vacuum degree display,valve operability,correct and adjustable interlocking for the SESRI heavy ion accelerator vacuum system.
