Multi-function Data Acquisition and Signal Processing System Based on LabVIEW
Shouguang Yao · Journal of Jiangsu University of Science and Technology · 2006
Considering the single function of the traditional instrument and the deficiencies of the traditional code programming language,a virtual multi-functional system for data acquisition and signal processing is developed by means of the software LabVIEW.The virtual instrument technology,the signal processing technology are adopted.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,signal analysis and processing module which can realize the online or offline signal processing in time domain,frequency domain,time-frequency domain and amplitude domain,the data management module which can realize the management of data sampled and processed such as the data query,transfer and deposit.In addition,the system can provide a friendly man-machine interface.It is also convenient to the system maintenance and function expansion.
