Abstract: In view of the existing limitations of traditional detection technology, to improve the degree of automation and precision of radar monitoring and control system, analyzes the characteristics of virtual instrument technology, design a set of automatic monitoring system, on the basis of the hardware selection. Summary of the graphical programming language LabVIEW advantage, the program can easily complete the data acquisition, signal analysis function. The application of virtual instrument technology in engineering detection has high precision, simple operation and high reliability and is easy to expand.

Key words: Virtual instrument, LabVIEW, Automatic detection, Signal processing
