System Design of Multithreaded Data Acquisition and Analysis Based on Virtual Instrument
FU Si-yon · 2014
This paper introduces the virtual instrument technology,Analysis of the advantages of its application in data acquisition and analysis system,study the transform methods of WGS- 84 geodetic coordinate to Space rectangular coordinate,design a Multithreaded GPS data acquisition system on this basis. Discussed in detail the method of data transfer between the Multithreaded,the program is run by the experiments show that Multithreaded programming techniques used in the notification queue way,can be a good deal with the problem of data security between Multiplethreads pass.
