基于AVR单片机的智能电表的硬件设计
摘要
电能表是我国电工仪表行业中产量最大的产品,随着高新技术尤其是电子信息技术的快速发展,电子式、多功能、高精度、多费率、自动抄表等产品的优势突显,且已经逐步成为电能表发展的主流。智能电表具有数据的保护,报警功能,断电的显示,负荷的控制,防窃电功能,远程抄表系统等功能,从计量到数据处理都采用以集成电路为核心的电子器件,从而取消了电表上长期使用的机械部件,随着智能化电表的发展,将最终取代传统电表在用户中的实用。本文设计的是一款基于AVR单片机的智能电表,采用ATmega16单片机、RN8209、485通讯等各个模块组成系统硬件电路。

Hardware design of intelligent electric meter based on AVR single-puter
Abstract
The electrical energy meter is in our country electrician measuring appliance profession the output biggest product, along with the high technology and new technology electronic information technology's fast development,the electronic formula, multi-purpose,the high accuracy, the multi-tariffs,copies product and so on table superiority to underline automatically particularly, and already gradually became the electrical energy table development the intelligent electric instrument has the data protection,the warning function, the power failure demonstration, the load control, against steals the electric work energy, long-distance copies functions and so on table system, uses take the integrated circuit from the measurement to the data processing as the core electronic device, thus has cancelled on the electric instrument the long-term use mechanical part,along with the intellectualized electric instrument's development,will substitute for traditional electric instrument in user practical finally. What design in this passage is a hardware design of intelligent electric meter based on AVR single-puter. It adopt various modules such as the ATmega16 monolithic integrated circuit, RN8209 and munications the transmission, and so on, to make up the system hardw
