The design of the data acquisition system based on LabVIEW

Xiaohu Chen

Abstract

In the fields of virtual instrument, the most representational graphic programmer language, Labview, is be introduced in this paper, the hardware and software of data acquisition system is be designed based on it, It includes the selection of sensor, data acquisition card and the design of the circuit of signal modulating, the programmer of the data acquisition, signal analyzing and the system of monitor. With the vibration signal of gear pump, by using the method of layida to confirm the alarm range, the monitor system can realize its function by mixing with labview and matlab. At last, the experiment that has be taked on the experimental platform indicates that the system can realize its function effectively
