虚拟化技术在电子直线加速器控制系统中的应用

Application of Virtualization in Control System of High Quality Electron Linear Accelerators

EPICS软件平台是国内外的大型加速器实验装置控制系统广泛采用的分布式控制系统,随着物理基础设施冗余度不断提高,控制系统平台资源出现高成本、低利用率的问题。针对大型加速器实验装置的需求,设计研发了基于虚拟化技术的电子直线加速器EPICS控制系统并成功应用,实现了控制系统资源整合,解决了维护困难、能耗高的问题。服务器、网络的虚拟化优化了控制系统结构,提高了整个系统可靠性,可用性和可维护性,同时节约了加速器装置的建设和运行经费。

EPICS software platform is a distribution control system for large-scale experimental accelerator facilities domestic and worldwide. With increasing requirements in upgrading the redundancy of the control devices,the tradition control system platform are faced up with a problem of high cost and low use rate. A virtualization based EPICS control system designed for large-scale experimental accelerator facilities was successfully developed. The application is helpful to integration control resources,to ease the difficulty to maintain and to lower down the high energy consumptions. The system consisting of the server and network virtualization, making the control system structure optimized,improved reliability,availability and maintainability as well as saving the construction and operation expenditures of accelerators.
