基于单片机的数据复用器研究

Research on Multiplexer Based on Single Chip CPU

本文探讨的是一个两路的数据复用器 ,该数据复用器采用异步串行通信方式 ,主要用 89C5 1单片机来实现。我们从硬件和软件两方面完成了数据复用器的设计与开发及调试 ,通过实际的安装 ,基本达到了该复用器的设计性能指标。它具有结构简单、体积小。

This paper describes a multiplexer which can multiplex two channels of data. It adopts asynchronous serial communication mode, uses Single Chip CPU-89C51 and other IC chips to realize the function. Development and adjustment are performed by two ways-hardware and software testing. The expected technical specifications are almost achieved. The multiplexer has the featnres of simple structure,small size and high reliability in data transmission.
