In this paper, we introduce the control system design,including human–machine interfaces, alarm system, historical data archiving system, and the software for access control. The software development followed the standard of Capability Maturity Model Integration(CMMIò) Level3, and the software had passed a third-party test, which indicated that the functionality and the reliability could fulfill the requirements of the radiation protection system.展开更多
