Upgrade of Monitoring and Interlocking Alarm System of Magnet Temperature for HIRFL

摘要

Accelerator magnet system is a major guarantee for ion beam running in vacuum tube over long-distance transmitting. Monitoring system of magnets temperature needs to fulfill the basic function of remote monitoring and alarming. In order to use unified interface and be easy to publish process variables (PVs), a new system is developed and presented in this paper. This software is designed based on Experimental Physics and Industrial Control System (EPICS), and a new device support file is also developed. It is realized to acquire temperature data from onsite devices, display the real-time data and store historical data automatically. When abnormal data is received it will alert immediately. The interlock module will work at the same time. After being running in the central control room for nearly two years, this system is proved to be extremely accurate and reliable.
