摘　　要：在EAST实验中,由于每个子系统采集的工程数据比较分散、相互独立,需要搭建一个能够整合工程数据的发布系统。文章介绍发布系统的设计与实现,通过把各子系统采集的数据整合到共享存储池中,实现工程数据的Web展现、长时间波形的图形展现;将工程数据中的脉冲数据存储到MDSPlus数据库,并实现脉冲波形的图例展现;通过时间戳检测子系统各个信道,当信道数据传输发生故障时发出信道预警。测试结果表明,系统能够稳定工作,可以使工程专家及时了解各子系统的工作状态,有利于确保实验装置正常运转。In view of the separation and independence of the engineering data of each subsystem in the EAST,it is necessary to develop a publishing system to integrate the engineering data.In this paper,the design and realization of the said publishing system is introduced.Acquisition data from each subsystem is integrated into a sharing memory pool,then the Web presentation and long-time waveform presentation are realized;the pulse data from engineering data is stored into MDSPlus database for pulse waveform presentation;the status of data channels in each subsystem is checked by time-stamp method,and the channel early-warning is sent out when the data transmission fails.The system works well in the EAST experiment.Engineering experts can trace the status of each subsystem timely,which ensures the normal operation of the project.
