采用FIFO技术Windows环境下的高速实时采集

比较了几种常见的数据采集卡的构成及其在 Windows环境下的采集方法 ,分析了各自的优缺点 ,简要介绍了 Win-dows的底层接口和 F IFO的结构原理 ,给出了采用 FIF O技术设计高速实时数据采集系统的方法。 FIF O技术的采用 ,既保证了 windows的多任务操作系统的特点 ,又保证了数据采集的可靠性 ,使在 Windows环境下无论对高速大容量数据采集还是对单次瞬变信号的实时捕获都提供了一种行之有效的方法。

High-speed real-time data sampling under Microsoft Windows by applying FIFO technology

The structures of several familiar data sampling cards and the sampling methods under Microsoft Windows are compared, and their defects and advantages are analyzed. The structure of FIFO and the kernel of Windows system are introduced briefly, and the method of applying FIFO technology to realize high speed real time data sampling is given. The adopting of FIFO technology makes both the high speed and huge capacity data acquisition and the capturing of instantaneous signals efficient.
