Design of Vacuum Monitoring System Based on EPICS for HIRFL

To solve the problems of the original vacuum monitoring system, the function of remote control and monitoring of vacuum equipment is realized. According to the characteristics of the Heavy Ion Research Facility in Lanzhou (HIRFL), such as large number, wide distribution, and complex types of vacuum equipment, this paper researches and designs a remote real-time vacuum monitoring system, including underlying hardware design, IOC software, and interface design. The system adopts Experimental Physics and Industrial Control System (EPICS) architecture design. The Programmable Logic Controller (PLC) is used to receive and process data from the underlying hardware devices and controllers, and upload the data to the EPICS IOC system by the network. The vacuum data is displayed in the User interface and remote controlling commands are issued. The system is currently running normally, and the design has been proved to meet the expected functions.
