摘要
在现代工业控制和科学研究过程中,经常需要对数据信号进行采集并加以分析,随着总线技术的发展,USB以其特有的高速、方便、灵活等优势迅速成为主要的信号传输总线。在对基于USB总线的数据采集系统的总体结构进行综述的基础上,对系统的固件程序、基于WDM的USB驱动程序及用户态应用程序等软件部分设计进行了较详细的讨论,认为上述软件部分设计对基于USB总线系统设计非常关键。
In the process of modern industrial contrial control and scientific research,it need often to collect and analyse data signal With the bus technique development, USB has become main signal transmission bus by its high speed, convenience and flexibility. On the basis of general description of architectural structure ,this paper discussed in detail its software design ,including its firmware program,USB driver based on WDM and application program of user mode.
