CYCIAE-100回旋加速器质子照相束流线控制系统的研制

为了对质子照相束流线设备进行远程监测与控制，实现束流线各子系统的安全联锁功能，研制了一套采用标准控制模型结构的分布式EPICS控制系统。该控制系统通过PLC组态实现了开关逻辑设备的安全联锁及工艺流程控制。核心控制系统采用EPICS建立了多个IOC作为控制器。针对不同CPU构架下的服务器搭建了交叉编译环境。针对数字电源设备与真空仪表设备使用StreamDevice完成设备驱动及通信协议的开发，并通过建立IOC动态数据库，实现了IOC对流设备和PLC信号的监测与控制功能。使用CSS设计OPI，实现了上位机对EPICS IOC中数据的透明访问。该束流线控制系统已成功应用于CYCIAE-100回旋加速器的质子照相物理实验中。通过长时间的运行，控制系统的可靠性、安全性得到了验证。控制系统的稳定运行，为质子照相实验的开展奠定了基础，对类似的控制系统研制具有一定的参考价值。

Design and Implementation of Control System for CYCIAE-100 Cyclotron Beam Line of Proton Radiography

In order to monitor and control proton radiography beam line equipment remotely and realize the safety interlock function of various subsystems of the beam line, a distributed EPICS control system was developed adopting the structure of standard control model. The system achieved the control for switch logic equipment safety chain through PLC. The core control system chose EPICS to set up many IOCs as a controller. The server set up the cross compiling environment under different CPU architectures. The device drivers and development of communication protocols were completed by using StreamDevice for digital power equipment and vacuum instrument equipment. The communication design for IOC and control functions of IOC convection equipment and PLC signals were completed through the establishment of the IOC dynamic database. Using CSS to design OPI, the host computer has access to data transparently in EPICS IOC. The beam line control system has been successfully applied to the physics experiment of CYCIAE-100 cyclotron proton radiography. The stable operation of the control system lays a solid foundation for the launch of the proton radiography experiment and has certain reference value for the development of similar control system.
