一种经济型单片机远程数据传递方案
A technical proposal for long-distance communication with single chip process & MODEM
【摘要】 介绍了一种仅用单片机串口(RXT,TXT)同调制解调器进行连接实现远程数据传递的通讯方案,该方案使用单片机资源较少,特别适合于现有仪表的改造。本文还介绍了为保证数据传递正确而提出的类XMODEM协议。实际应用表明本方案实现简单、可靠,是一种较有价值的方案。
【Abstract】 A technical proposal for long-distance communication with MCS -51 single chip process and MODEM is developed.It only employs the serial port in MCS-51 single chip process,so it is compatible to improve exitiog instrument for long-distance communication.A communication protocol is introduced for assuring data transmission.The fact has approved that the proposal is sample and credibility.
