| Abstract: | The realizing methods of the data acquisition and signal analysis was introduced based on LabVIEW 7 Expreas. It set up a virtual instrumentation with the function of data acquisition and signal analysis, based on computer and USB2002 data acquisition card and software of LabVIEW. The system includes the signal acquisition and control module which can realize the data acquisition with single channel or multi-channels as well as memory and signal recall. Reducing the cost of the equipment, the system can also provide a friendly human-machine interface. In addition, it is convenient for the system maintenance and function expansion. It is also convenient to the system maintenance and function expansion. The system has good verification and shows the superior performances in the power system. |
