关于EPICS复杂系统

EPICS 是一套软件工具和应用程序，为建立分布式控制系统提供软件基础设施，用于操作粒子加速器、大型实验和大型望远镜等设备。这种分布式控制系统通常由数十台甚至数百台计算机组成，通过联网，它们之间可以进行通信，并从中央控制室，甚至通过互联网远程控制和反馈设备的各个部分。

高带宽软实时网络应用

EPICS 使用客户端/服务器和发布/订阅技术在不同计算机之间进行通信。大多数服务器（称为输入/输出控制器或 IOC）执行现实世界中的 I/O 和本地控制任务，并使用强大的 EPICS 专用网络协议 Channel Access 和 pvAccess 将这些信息发布给客户端。这些协议专为 EPICS 的高带宽、软实时网络应用而设计，这也是 EPICS 可用于构建由数百台计算机组成的控制系统的原因之一。

灵活可扩展

在美国先进光子源国家实验室，EPICS 被广泛应用于加速器和许多实验的控制系统中。约有数百个 IOC 直接或间接地控制着机器运行的几乎每一个方面，而控制室中的 40 台工作站和服务器则提供更高级别的控制和系统操作界面，并进行数据记录、归档和分析。

EPICS蓝图

EPICS是通过开放源码的协作过程开发的，任何人都可以自由地为EPICS系列软件做出贡献。除此之外，EPICS 的主要用户（通常是大型科研机构）还聚集在一个开放的 EPICS 理事会中，为 EPICS 的未来发展方向制定路线图。
