新型智能電表的設計

摘要：電能表是我國電工儀表行業(yè)中產(chǎn)量最大的產(chǎn)品，隨著高新技術(shù)尤其是電子信息技術(shù)的快速發(fā)展，電子式、多功能、高精度、多費率、自動抄表等產(chǎn)品的優(yōu)勢突顯，且已經(jīng)逐步成為電能表發(fā)展的主流。智能電表具有數(shù)據(jù)的保護，報警功能，斷電的顯示，負荷的控制，防竊電功能，遠程抄表系統(tǒng)等功能，從計量到數(shù)據(jù)處理都采用以集成電路為核心的電子器件，從而取消了電表上長期使用的機械部件，隨著智能化電表的發(fā)展，將最終取代傳統(tǒng)電表在用戶中的實用。本文主要應用手持單元，87C51單片機，232通訊與485通訊等各個單元來完成數(shù)據(jù)的傳輸,費率的計算，數(shù)據(jù)的顯示，報警，遠程抄表控制，使電表實現(xiàn)智能化。

Design on New Intelligent Electric Meter
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 mainstream. 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. In this dissert the hand-hold unit, the 87C51 monolithic integrated circuit and 232 communications are used and so on each unit completes the data with 485 communications the transmission, the tariff computation, the data demonstration, the warning, long-distance copies the table control, causes the electric instrument to realize the intellectualization.
