摘　　要：介绍了为高重频自由电子激光装置的注入器样机沿线布置的数台低能段电源、功率源以及高能段电源等研制的一套基于EPICS的控制系统。由于EPICS自身在加速器领域的国际通用性和国内较为广泛的应用技术基础,本系统采用EPICS的体系结构来部署,利用网络化的分层分布式结构,在TCP/IP协议之上建立CA的通道访问机制,为客户和服务器分别提供应用接口子程序库,并通过其特有的基于数据流的设备通讯驱动软件模块完成了所有底层电源设备的驱动开发,以及基于CSS的客户端控制软件。本系统满足用户对电源的参数设置、状态监测和操作控制等功能的实时集中远程监控需求,以及与装置其他相关子系统的数据共享,提高了装置运行效率和可靠性。This paper presents a control system based on EPICS(Experimental Physics and Industrial Control System)for multiple low-energy and high-energy power supplies configured along the injector prototype of a high-repetition-rate XFEL(X-ray Free Electron Laser)facility.Due to the global applicability of EPICS in accelerator technology and its established technical foundation in China,the system is designed based on the EPICS architecture.It employs a hierarchical distributed network structure,establishes Channel Access(CA)based on the TCP/IP protocol,and offers application interface subroutine libraries for both clients and servers.The driver development of all underlying power devices is completed through a unique device communication driver software module based on data flow.And the client control software is developed based on CSS(Control System Studio).This system fulfills users’requirements for real-time centralized remote monitoring and control of power supplies,as well as data sharing with other related subsystems,which improves the operating efficiency and reliability of the device.
