摘　　要：多通道模入数据采集卡的设计根据电站检测中数据的测量与控制问题提出,本文在对数据采集卡的硬件组成进行综述的基础上,对系统的固件程序、基于WDM的USB驱动程序和用户应用程序等各部分软件的设计和协同工作进行了详细的介绍,并将采集模块应用于某型电站发动机进行检测试验,得到次级点火电压波形,和电站发动机标准波形进行比较可见数据的采集效果良好,试验结果证明设计方案是可行的,满足了预期的应用目的和设计的精度要求。The design of multiple analog signal input data acquisition board is to resolve the measuring and control problems in the process of testing generator. On the basis of general description of hardware design, this paper introduce in detail its software design and cooperation, including its firmware program, USB driver based on WDM and application program. Test the design on a certen generator and obtain the waves of secondary gnition voltage , the result of compearing the waves with the standard waves is ideal, So the design schemeire is advisable, reach the applied purpose and design accuracy requirement.
