摘　　要：基于某型号位标器性能评估系统提出的测试任务,需要开发能够满足性能评估测试任务中的高速、多通道独立采集等要求,通过以WDF驱动框架为基础,在PXI总线下开发出四通道LVDS图像采集卡的驱动程序。通过C++封装动态链接库以及用C#开发的测试界面进行四通道LVDS图像采集卡的数据采集测试,对其驱动程序的正确性、稳定性以及实用性进行了测试,得到基于WDF的四通道LVDS图像采集卡的驱动程序运行正常,且符合现场测试任务的要求的结果。Based on the requirements of high- speed and multi- channel independent acquisition in performance evaluation of a certain type of position marker＇s test task, the four-channel LVDS image acquision card＇s driver is developed on the PXI bus, based on the WDF-driven framework. Through the C ＋ ＋ package dynamic link library and C # development of the test interface for four-channel LVDS image acquisition card data acquisition test, the correctness, stability and practicality of the test are tested, The driver of the four-channel LVDS image acquisition card based on WDF is operating normally and meets the requirements of field test tasks.
