本文提出了一种不受微机采样速度的影响，采样频率仅仅只取决于Ａ／Ｄ器件的采样频率，只要选择高速Ａ／Ｄ，就能做成一个高速的数据采集系统。本文给出了该系统的工作原理框图以及时序关系图。并对其工作原理作了简单的介绍，并给出了实际应用时的图片和工作时的程序。
This paper presents a speed independent of the sampling speed of the computer. The sampling frequency only depends on the sampling frequency of the A / D device. As long as the high speed A / D is selected, a high speed data acquisition system can be made. This article gives the working principle of the system block diagram and timing diagram. And a brief introduction of its working principle, and gives the actual application of the pictures and work procedures.
