Abstract: In order to improve the accuracy of the data acquisition system, reduce development costs and improve development efficiency, a data acquisition system was designed on the basis of the development tool research for LabVIEW virtual instruments. The FPGA programming mode and network flow technology are adopted in the system to execute real⁃time transmission of the mass data, which is analyzed, processed and stored. The real⁃time controller cRIO⁃9025 made by National Instruments (NI) is used in the system hardwares to achieve 16⁃channel data acquisition and storage. Simulation and experimental results show that the data acquisition system can realize the accurate real⁃time data acquisition and analysis, and meet the project requirements.
