摘要
讨论了两种远程数据采集系统设计方案 ,重点介绍了有线链路方案 ,该方案采用AT89C5 1与通用异步收发器 82 5 1接口和MODEM实现单片机与PC机在有线公共电话网中进行远程数据通信技术。并在工程上将其实现。本系统结构简单 ,性能稳定 ,适用范围广 ,可扩展性强 。
This paper discusses the designs of two remote data collecting systems and mainly introduces the design of wired link, by the numbers introduce technique of interface between AT89C51 & 8251, and control intelligent modem to implement remote data communications between single chip microcomputer and PC by the PSTN. It was applied to engineering. The system is simple in structure, is stable performance and has high utility values for every factory. It has power supply market.
