基于虚拟仪器和高速数字化仪的长时间数据采集系统设计

set of high-sampling rates, long-term data acquisition and analysis system based on the Virtual Instrument LabVIEW and the high-speed digitizer PCI-5124. The system has 20MHz sampling rate or even higher, it realized the multiple function of real-time signal acquisition lasted minutes, real-time storage, playback, signal analysis, report form printing, etc. The system experiments show that: this design proposal takes some advantage of easy programmer, high versatility, good transplantation and easily worked, and so on.
