Design of data acquisition system based on LabVIEW
This paper introduces a method of data acquisition and processing based on a virtual instrument. LabVIEW 2014 is the software development platform focusing on the virtual instrument system for data collection and analysis. The basic idea of waveform acquisition and measurement is introduced briefly, and its application to modern motor speed control system is presented. The system can perform data collection, analysis, display, storage, printing and historical playback. It has a good human-computer interaction interface, easy to maintain and expand. The practical application shows that the system is simple and meets the technical requirements of the system test.
