Design and realization of engineering experiment data publishing system for EAST
Zhu Ying-fei · Journal of Hefei University of Technology · 2010
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.
