BEPCⅡ数字化辐射防护平台研究及应用

Research and Application of Digital Radiation Protection Platform for BEPCⅡ

平台在BEPCⅡ(北京正负电子对撞机二期工程)的人身及设备防护安全需求上根据粒子加速器辐射防护最新发展理念,结合计算机控制技术、可编程序控制器技术、门禁控制技术、多媒体视听技术、网络技术等建立起来。它集成了人身安全联锁PLC系统、人身安全联锁门禁系统、剂量监测系统、急停按钮警示系统等,各子系统均有独立的上位机。平台采用分布式控制系统,将从各子系统采集到的信息进行集中处理后可对加速器辐射安全做出评估。

Under the personnel and equipment safety requirement for BEPCⅡ,according to the development idea of radiation protection for particle accelerator,combine with computer control technique,programmable controller technique,access control technique,multimedia audiovisual technique and network technique,design this digital distributed control radiation protection platform.It comprises personnel safety interlock PLC system,personnel safety interlock access control system,radiation dose detection system,tunnel ventilation system,emergency pushbutton warning system and so on,every subsystem has independent host computer.The platform adopt distributed control system,by using the wellhandled information form every subsystem,we can make an evaluation about the accelerator radiation protection safety.
