摘要:

通过对双积分A/D转换过程及其原理的分析,结合8031单片机定时计数器的特点,设计出一种新的A/D转换电路.详细介绍了这种转换电路的硬件原理及工作过程,给出了实用的硬件电路与软件设计框图.通过比较分析,可以看出这种A/D转换电路性能价格比较高,软件编程简单,并且转换速度和精度优于一般的A/D转换电路.这种设计思路为数模转换器(A/D)的升级提高指出一个明确的方向.

Abstract:

Through the analysis of the double integral A/D conversion process and its principle, combined with the characteristics of the 8031 single-chip microcomputer timing counter, a new A/D conversion circuit is designed. The hardware principle and working process of this conversion circuit are introduced in detail, and a practical hardware circuit and software design block diagram is given. Through comparative analysis, it can be seen that the performance price of this A/D conversion circuit is relatively high, the software programming is simple, and the conversion speed and accuracy are better than the general A/D conversion circuit. This design idea points out a clear direction for the upgrade of digital-to-analog converters (A/D).
