Seismic Data Acquisition System Based On Sound Card and LabVIEW
Liu Ying · Microcomputer Information · 2010
This paper first introduced the hardware features and software features of the sound card.Taking the computer sound instead of current acquisition card as hardware and the engineering software LabVIEW that analysis and processing function is very powerful as software development platform,a kind of sound card acquisition system with higher sampling precision,middling sampling frequency and better flexibility is designed.It has realized several functions such as data acquisition,display,data store,signal analysis (i.e.time-domain analysis and frequency-domain analysis)and so on.The seismic signal has carried out with the system used external trigger or continued acquisition.The system has been used in experiment course teaching.
