摘　　要：介绍EAST真空及加料监控系统底层和顶层的架构设计、连锁保护设计、运行模式设计以及系统部署。在底层架构中,真空抽气和加料监控系统分别采用两套相互独立的光纤环网拓扑,构成双光纤环网结构。顶层设计主要采用符合大科学装置规范的实验物理与工业控制系统(EPICS)架构。系统设计主要特点是将底层双光纤环网结构拓扑和顶层EPICS架构相结合,构建了大型分布式真空抽气和加料数据采集与监视控制系统。测试结果表明整套监控系统运行稳定可靠,该监控系统不仅为EAST装置实验提供了可靠支撑,同时也为未来其它大科学装置的监控系统构建提供参考和借鉴。Supervisory control and data acquisition(SCADA) framework of bottom layer and top layer,interlock protection, operational mode and system implementation were described. In bottom layer, vacuum pumping system and fuelling system are adopted to two different topological structures of optical fiber ring network. The top layer uses the experimental physical and industrial control system(EPICS) architecture to meet the requirements of the large-scale scientific facility. The topological structure of optical fiber ring network and EPICS framework are combined to develop the largely distributed SCADA system. Test results show that the control system is stable and reliable. The SCADA system provides not only reliable support for EAST, but also a good reference for developing other SCADA system of large-scale scientific facility in the future.
