摘　　要：本文结合探地雷达中的PCI数据采集卡,介绍了WDM驱动程序模型结构,对PCI设备的存储器映射、数据传输以及驱动程序与应用程序之间的通信等主要问题做了讨论。介绍了运用NuMega公司的DriverStudio开发PCI设备WDM驱动程序的方法及程序实例,并实现了驱动程序的安装与调试,该驱动程序调试通过,运行稳定。最后对实际中遇到的问题及其解决办法做了总结。This paper illuminates the mode structure of the WDM driver. Taking PCI bus sample card design in the Ground-Pene- trating Radar as a reference, author discusses some key techniques in programming the WDM driver such as memory mapping, data transmission and the communication between application and driver. On the base of these discussions, the methods of WDM driver under DriverStudio and the main courses for PCI device are presented. Meanwhile, how to debug and install the driver are explained. It＇s proved that the drivers run steadily. In the end, the author sums up the questions met in the practically design and gives the solve methods.
