摘要
随着数字处理技术的发展,模拟/数字转换(A/D转换器)在数据采集系统中的应用越来越广泛。通过对A/D转换原理的介绍,给出了以AT89C51单片机为核心控制芯片,通过对MAX197模数转换芯片的控制进行数据采集的接口电路和程序流程,为设计数据采集系统提供了一种方案。
Along with the development of digital technique, the application of analog/digital converter (A/D converter) is increasingly extensive in data acquisition system. Based on the principle of A/D converter, an interface circuit as well as the program flow is put forward, in which a single chip microcontroller AT89C51 is taken as the core, controlling MAX197 to acquire data. This study provides a scheme for data collection system.
