无线电能表抄表系统设计

无线电能表抄表系统是一项基于ADE7755高精确度电能测量芯片、无线通信芯片nRF905、微控制器Atmega16L以及1602液晶等辅助电路的综合应用技术，实现短距离（约1000米）无线抄表。本系统能够实现各个电力用户的用电自动计量、存储、以及无线传输，方便电能表抄表人员对用户用电信息的采集。本系统分为三个模块：手持无线抄表器、客户端无线电能表以及客户端管理器，他们之间进行无线通信。

Design of Wireless Electric Energy Meter Reading System

The Wireless Meter Reading system of electric energy meter is a kind of synthesis application technology based on the auxiliary circuits of a high precision electrical energy measuring chip ADE7755, a wireless communication chip nRF905, a microcon- troller Atmega16L and a liquid crystal of width/height is 16/02 thus realizing the short distance wireless meter reading （about 1000 meters）. The system can automatically measure, store and wireless- transmit the related data, very convenient for the meter checkers to gather the information of user＇s electric energy meters. The system is made up of three modules, a handheld wireless meter reading de- vice, a wireless electric energy meter and a manager at the client end. The above three parts can wireless-communicate one another.
