EAST装置技术诊断数据采集系统设计

Design of the data acquisition system of technical diagnosis about EAST device

介绍了EAST托卡马克核聚变实验装置技术诊断数据采集系统设计。系统采用双缓冲模式、多路采样信号的同步、分布式数据采集、数据库管理等技术,解决了技术诊断的高速、连续与同步采集问题。该模式的技术诊断数据采集系统,已在磁体测试装置上使用,多次实验表明该采集系统性能稳定,能够满足聚变工程需求。

In this paper the data acquisition system of technical diagnosis of the Tokamak experimental device for nuclear fusion is introduced. The system uses techniques, such as double buffer modes, synchronization acquisition of multi-channel signals, distributed data acquisition and database manage, to solve the high speed and continuum and synchronization data acquisition problems about technical diagnosis. This mode of the data acquisition system has been used in the test facility of the magnet; many tests indicate tranquilization of the data acquisition system. It will be able to meet the demand of fusion engineering.
