摘要
中性束注入(NBI)是磁约束核聚变装置等离子体加热和电流驱动的重要手段。依据东方超环(EAST)NBI实验运行特点,设计了基于网络通讯的集散式控制系统。NBI控制系统采用计算机网络技术,按照控制层次分为远程监控层、服务器控制层和现场控制层,三层控制结构易于系统功能扩展与设备升级。一条束线的两个离子源可以独立运行控制,这为EAST第二条束线控制扩展奠定基础。实验表明,NBI控制系统具备了远程监控、连锁保护和数据处理功能,满足了NBI实验运行的自动化和可视化的需求。
Neutral beam injection （NBI） is an important method of plasma heating and plasma current driving for magnetic confinement fusion device. A distributed control system is designed in this paper according to experimental operation characteristics of NBI on Experimental Advanced Superconducting Tokamak （EAST）. The NBI control system based on network technology, classified according to control level, consists of remote monitoring layer, server control layer and field control layer. The three-layer control systematic architecture is easy for extending system functions and upgrading devices. Both ion sources of one NBI beam line are designed to operate independently, which lays a foundation for developing control system of the second beam line on EAST. Experimental results demonstrate that the visualization and automation of NBI experimental operations are successfully implemented by remote monitoring, interlock protection, and data processing.
