智能电力监控系统远程数据传输的方案设计

The Scheme of Intelligent Instrument for Long-distance Communication and Control

介绍一种单片机控制实现远程数据传递的通讯方案 ,该通信使用单片机资源较少 ,只使用 3根线(RD ,TD ,GND)就可以进行控制 ,特别适合于智能仪表的远程监控。同时还介绍了为保证数据传送正确而提供的类XMODEM协议。在电力监控系统应用该方案表明 ,其实现简单、可靠。

A technical proposal for long-distance communication with MCS-51 single chip processor and MODEM is developed. It only employs serial port in MCS-51 single chip processor and 3 wires (RD, TD, GND) for control; so it is compatible to intelligent instrument for long-distance communication and control. A communication protocol is also introduced for assuring data transmission. The fact has approved that the proposal is sample and credible in the scheme of intelligent instrument.
