摘　　要：本文给出了一种基于PXI总线的数据采集系统的硬件原理框图。针对该硬件系统,采用DriverWorks驱动程序开发工具开发了相应的WDM驱动程序和控制台应用程序。将该驱动程序和控制台应用程序与相应的数据采集硬件卡结合起来使用,可以实现数据采集、数据传输、数据存储和数据显示功能,从而构成一个完整的数据采集系统。当接口芯片采用突发传输模式时,该数据采集卡的理想传输速率可以达到132MB/s。该系统可以用于中高速数据采集场合。A theoretic diagram of data acquisition system based on PXI bus was proposed in this paper. To be aimed at this hardware system, Driverworks was adopted as the driver development tools to develop the corresponding WDM driver and console application. Combining this driver and console application with corresponding data acquisition hardware card, all the functions were realized including data acquisition, data transmission, data storing and data displaying, therefore, a complete system of data acquisition was constructed. The burst transfer is up to 132 MB/s if burst mode of the interface chip is selected. This system can be used in medium and high speed data acquisition environment.
