数据采集系统设计

The Designing of the Data Acquisition System

介绍了以PC机为主机、单片机为从机的数据采集系统的工作原理和设计方法。新的数据采集系统主要由A/D转换器ADC0809、8051单片机、LED显示器和PC机组成。其中PC机控制单片机系统定时采集一路电压信号并在2个LED显示器上显示采集到的数据,同时PC机能够将采集到的电压数据绘成曲线并进行保存。

This article mainly demonstrates the designing approach and the working principles for the data acquisition system with the personal computer as a host and the single chip microcomputer as a slave. The data acquisition system here consists of A/D converter ADC0809, 8051 single chip microcomputer, LED display and personal computer. The personal computer controls the single chip microcomputer system to collect a voltage signal and displays it on two LED. At the same time, the personal computer draws a curve in light of the acquired data and then saves them.
