摘要
介绍了中科院等离子体所HT-7托卡马克装置上中性束注入(NBI) 控制系统设计方案和实现方法。系统采用分级分布式结构, 由PLC时序控制单元、数据采集与处理单元、参数预设单元和真空与低温监控单元组成; 各单元采用网络通讯互联, 实现数据的传输和控制命令的执行。系统成功地应用于实验并获得理想的实验结果, 为中性束注入加热的稳态运行提供可靠保障。
The design and realization of control system of Neutral Beam Injection (NBI) for HT-7 tokamak are introduced. The system is multilevel and adopts distributed structure, consisting of PLC timing control unit, data acquisition and processing unit, parameter setting unit and monitoring unit of vacuum and low temperature; each unit is interconnected through internet to achieve data transfer and control command executing. The system has been applied successfully in experiment and get many ideal results, which also provides a guarantee for the reliable running of neutral beam injection.
