摘要: 介绍了实验物理和工业控制系统（EPICS）的总体结构和特点，以及极向场电源控制系统监控网络的结构和特点，特别是EPICS设备支持在极向场电源控制系统的监控网络中的开发和应用。系统实现了实时监控极向场电源系统的现场设备和开关分合控制，实现了对极向场电源控制系统的电源控制单元的配置参数设置、控制模式的设置、时序控制等，并能及时报警、定位故障点。该系统监控的数字量及模拟量信号近2000路，且支持多用户操作，具备良好的跨平台移植性和扩展能力。经实验测试，该应用运行稳定，能满足极向场电源控制系统监控网络的需求。Abstract: This paper describes architecture and characteristics of experimental physics and industrial control system(EPICS), and the structure and characteristics of the monitoring network of the poloidal field power supply control system based on EPICS. It focuses on the development and application of EPICS device support in monitoring network of poloidal field power supply control system. The EPICS designed in this paper monitors the status, sends the command of opening or closing the switches, sets the configuration parameters, and controls the time-sequence for the local controllers in the poloidal field power supply control system. When a breakdown occurs, it can give an alarm and the software can locate the system fault. This system can monitor nearly 2 thousands digital and analog signals and support multi-user operating. The good features of EPICS are very helpful for the integration of the poloidal field power supply control system.
