基于MDSplus的NBI数据采集系统
|
摘要
为了中性束注入(Neutral Beam Injection,NBI)系统的数据格式与东方超环(EAST)兼容,方便实验结果共享和国际学术交流,设计了基于MDSplus(Model Drive System plus)的NBI数据采集系统.数据采集模块采用双缓冲技术和多线程机制,解决了NBI连续长脉冲数据采集问题.数据存储模块采用MDSplus数据存储格式,通过MDSplus软件开发包的j Scope软件访问实验数据,解决了NBI数据格式不统一和实验数据共享问题.该系统在测试台中满足了实验运行需求,为投入应用到下一轮EAST-NBI长脉冲注入实验中奠定了良好的基础.
In order to make the data format of NBI(Neutral Beam Injection) system compatible with EAST data and to make international exchange of experimental results effectively, an NBI data acquisition system based on MDSplus(Model Drive System plus) is developed. Double buffer technology and multi-thread mechanism are adopted in data acquisition module to achieve continuous and long-pulse data acquisition. Data storage module selects MDSplus and j Scope which can access the experimental data and is packaged in MDSplus' s program developing tools to resolve the problem of unifying NBI data format and sharing NBI experimental data. The system has met the requirements of the experiment in the test and lays a good foundation for the next round EAST-NBI long-pulse injection experiments.
