外围板卡的高速数据采集的实现

Data Collecting from Periphery Boarding in High Speed

分析了目前各数据传输方式的优缺点,探讨了在Windows2000/XP通过动态链接库采集数据方法的权限问题及解决方法。最后,基于12位高速A/D板,使用所提出的方法在VB6.0平台上编写数据采集程序,结合磨削过程监测中声发射信号采集的任务,实现了声发射信号的高速信号采集。

The advantage and disadvantage of the way of data transferring are analyzed in this paper.The limit of data transferring with DLL and the solvent are discussed.Finally,based on fast 12 bit A/D converter board,the program of data collection by VB6.0 with the presented methods are made,collecting the acoustic emission signals on real time.
