Design and Application of the Pressure Measurement System Based on AC1030 High-Speed Acquisition Card

According to the characteristics of these pressure waveforms, we firstly design the gross structure of the acquisition system and make the matching and triggering circuits corresponding to the AC1030 acquisition card. Secondly we place a sampling length to the interface through programming, and meanwhile circularly start up the A/D conversion, so the way of memory of the memorizer changes into the memory of ring type. Lastly playback and process the data of acquisition in the way of virtual instrument. The experimental result shows that the acquisition system has got the good data waveforms and achieved the expected result.
