A Multi-type Data Acquisition Platform Based on LabVIEW

[摘要] This paper presents a LabVIEW based platform for acquiring multi-type data. With the help of virtual instrument technique, the platform is capable of sampling the current signal, frequency signal, switching signal and resistance signal, judging the validity of data and analyzing the characters of data as well. The framework of the acquisition platform comprises of two parts, i.e., the software part is developed in LabVIEW language and the hardware part is built by National Instruments (NI). In addition to its major functions, the platform supports storing and reviewing the data and analysis results, and possesses a friendly graphical user interface (GUI), which facilitates the maintenance and function extensions. The engineering practices reveal that the proposed platform has advantages of readily-operating and stable functions, and satisfies the diverse requirements of data acquisition.
