Data Acquisition and Processing System Based on LabVIEW

A data acquisition and processing system has been designed aiming at reducing the traditional laboratory apparatus costs and expanding the data processing functions.NI data acquisition card(NI 6251)collected the signals,and the software system for signal analyzer、collector and stored was developed by using LabVIEW graphical programming language.The result shows that the system can replace traditional data acquisition instrument,finishing data acquisition、analyzing and displaying quality.The system also has advantages in friendly interface,powerful,easy expansion and maintenance.It can be widely applied in laboratory virtual experiment platform and industrial field.
