| Abstract: |
| In order to overcome the shortcomings of high cost of specialized data acquisition and high professional requirement of traditional programming code, this paper designs data acquisition and processing system based on sound card by using LabVIEW software. Multi thread Parallel Model is applied in the system including data collection module, data processing module and waveform display module. The experimental results prove that the system has advantages of simple design, high sampling precision and good expansibility. |
