摘　　要：MDSplus实时数据采集系统是EAST长脉冲放电试验的基础工程。依据时间片概念及MDSplus数据库特性,设计系统架构,利用双缓冲机制统一数据采集模块,借助生产者-消费者模式及Liunx多进程机制设计MDSplus存储模块,基于缩略图机制,实现数据访问模块。系统满足设计目标,为后续EAST实验打下坚实基础。MDSplus real-time data acquisition system is the foundation engineering of EAST（ experimental ad- vanced superconducting Tokamak） long pulse discharge experiment. Based on the time slice concept and the characteristics of MDSplus database, the system architecture is designed. By using of double buffer mechanism, data acquisition modules are unified. By means of producers-consumers mode and Liunx muhi-process mecha- nism, MDSplus storage module is de mechanism. The system satisfies the signed design , and the data access module is implemented by using snap-graph goals, and lays a solid foundation for the subsequent EAST experiments.
