电子电能表与电能测量技术讲座 第十七讲 基于无线网络的电能远程抄表系统的设计与实现

Meter Romote Copying System Based on the Wireless Network

介绍一种利用民用无线网络实现电能表远程抄表的系统。该系统主要由电能计量、数据采集与显示、数据集中、通讯与 控制、短信收发、无线网络与计算机等部分组成。其中电能的计量采用AD7755实现,数据的无线传输与控制利用单片机AT89S51 向短信收发模块发送AT指令来实现。

A system based on wireless network is composed of electricity meter, data acquiring and displaying, data collecting, communicating and controlling, short message receiving and sending. GSM network and computer. Among these parts AD7755 is the core of the electricity meter, and data transmitting and controlling is completed by means of AT89S51 transmitting AT command to GSM module.
