Design And Implementation Of Long Pulse Data Measurement And Control System Based On PXI

In actual production applications,a large number of engineering scientific research experiments and applications are pulsed.Pulse type experiments are divided into short pulse operation mode and long pulse operation mode.In the long-pulse operating mode,with the long-pulse steady-state operation of the system under test,it is necessary to wait for the test to be completed before processing and analyzing the experimental results.In addition,with the needs of scientific research experiments and applications,the accuracy of data sampling is continuously improved,and the amount of data is gradually increasing.After the system is finished,reading and processing the data at one time will not only increase the network transmission burden,but also increase the data processing.And the difficulty of analysis.Therefore,research on data synchronization measurement,control,control and storage processing technologies under long-pulse experiment operation and application mode,to realize the real-time synchronous measurement,remote control,and real-time storage processing of test data by scientific research staff during long-pulse experiment operation,will have Very important practical significance.This subject mainly researches from the following three aspects,that is,the synchronous measurement of long pulse data,the real-time transmission and storage of long pulse data,and the realization of remote control of long pulse data.Through the research and use of synchronous data measurement and control and diagnosis technology,data compression processing technology,network communication technology,and database segmented data storage processing technology,local precise and precise measurement and control of long pulse signals to be measured,network transmission and distributed data are realized.Storage,long pulse segmentation recording of database and other functions.This subject proposes an accurate long-pulse data measurement and real-timeprocessing algorithm,and develops a long-pulse steady-state data storage and processing system based on database segmentation technology.After testing,the system can run safely with high reliability,high stability.The research significance of this subject is mainly reflected in the research results that will provide reference and reference for solving the data processing problems in long-pulse steady-state experimental applications,which can realize the real-time measurement and control of the original long-pulse data in the experiment,distributed storage,etc.It has certain universality and practical application value.
