“自适应”方式的数据采集系统的研究

为了解决数据采集系统的采集速度的问题，提出了一种“自适应”方式的数据采集系统，即利用硬件逻辑控制器对A／D转换与数据存贮进行控制的方式，使数据采集速度仅受A／D转换速度限制，从而有效地提高了系统的采集速度。

The Research of Adaptive Sampled-data System

In this paper, the factors which limit sampling frequency is discussed,and a new way of designing sampled-data system is introduced. The system which is designed in this way is called adaptive sampled-data system. It does not use a CPU,but use logical control circuits to control the procedures of data sampling and storing.Consequently, the speed of the system is raised.
