基于单片机的等比例采样器的研制

A study on the instrument of equal proportion sampling based on SCM

本文介绍了一种简单的等比例采样器系统,该系统以AT89C51单片机为核心,主要包括AD转换部分,设定数据的存储以及设定数据的显示,液晶显示屏与AT89C51的接口．步进电机的控制等几大部分。该系统硬件电路结构简单、稳定、功耗低,较好地实现了等比例采样器所要求的各项功能,所以该系统有很高的实用价值。

This paper Introduces a kind of simple system about an instrument of equal proportion sampling. This system based on AT89C51, it main contains several parts, such as the part of analog to digital, the memory and display of the setted data, the interface of LCD and AT89C51, the control of step-motor and so on. This hardware has the advantages of easy circuit , reliability and low power. All functions of the instrument achieved perfectly, so it has high practicality.
