Development of beamline control system for Hefei Advanced Light Facility

Abstract

Abstract The design and the control scheme of beamline control system for Hefei Advanced Light Facility (HALF;Hefei, People's Republic of China) which is under construction is described in this paper.It mainly includes, equipment protection safety, personal protection safety,fast signal interlock and status monitoring and fault diagnosis system. In this control system ,the human presence perception function has been added to the personal protection safety system. Multi-parameter status monitoring of key equipment on beamline station can automatically alarm equipment failures and send relevant personnel timely notifications. At the same time, it can also provide early warning on the health status of key equipment on the beamline. The system not only improves the safety and reliability of beamline control, but also increases the degree of automation and intelligence, reduces the workload of operation and maintenance personnel, and improves operation and maintenance efficiency.
