随着J-T EX T装置的发展，原有的数据采集系统在稳定性、模块化、采样率等方面已不能满足装置运行的需要，所以需建立一套新的数据采集系统来满足实验需求。本文介绍了基于 PXI Express的托卡马克分布式高速同步数据采集系统的设计与实现。系统的采集单元由 PXIe机箱 NI PXIe-1062Q、PXIe控制器NI PXIe-8133和高速同步数据采集卡NI PXIe-6368组成，兼容ITER CODAC最新标准，具有良好的机械封装性、模块化程度高和高采样率等优点。系统采用同步差分采集方式采集实验数据，并将数据存储于核聚变领域通用的MDSplus数据库中。测试和使用结果表明，系统能在2 MSps采样率下连续稳定工作，可较好地满足装置运行的需要。

With the development of J-TEXT device ,the original data acquisition system can’t meet the experiment’s requirement on stability ,modularity and sampling rate ,so a new data acquisition system needs to be built .This paper introduces the design and implementation of the distributed Tokamak synchronous high-speed data acquisition system based on PXI Express . The acquisition unit consists of PXIe case NI PXIe-1062Q ,PXIe controller NI PXIe-8133 and high-speed synchronous data acquisition card NI PXIe-6368 ,compatible with the latest standard of ITER CODAC ,so it has good mechanical sealing ,strong modularity and high sampling rate etc .The system takes a synchronous difference acquisition for diagnosis signal . The data storage adopts MDSplus which is the general database in the nuclear fusion field . The test and experimental results show that the system can work continuously and stably at 2 MSps sampling rate ,and meet the requirement of experiment device’s operation well .
