Real-time sliced data storage in real-time control system

To archive data in real time without disturbing the response time of real-time control system,a storage method of realtime data based on slices is presented.An archive node is added to the real-time control system in the process of real-time control,the data in real-time node is sliced by time and passed to the archive node,the archive node slices stored data to the storage system.This data sliced stored mode only need to use little control cycle time of real-time control node,combined with added archive node to complete real-time data storage,and it can read and analyze data in real-time control process.This method is applied to the EAST plasma control system,it is possible to find a way for analysis of the long pulse discharge and future steadystate discharge experimental data for real-time storage and read.It can also provide a reference for other real-time control system for real-time data storage.
