1、基于單片機(jī)的智能IC卡電表設(shè)計(jì)(硬件系統(tǒng))學(xué)院畢業(yè)設(shè)計(jì)(論文)系(院)專(zhuān)業(yè)學(xué)生姓名班級(jí)學(xué)號(hào)指導(dǎo)教師完成日期年月日TheDesignofIntelligentICCardMeterBasedonSingleChipMicrocomputer(HardwareSystem)總計(jì)畢業(yè)設(shè)計(jì)(論文)表格插圖頁(yè)個(gè)幅32222南昌工程學(xué)院本科畢業(yè)設(shè)計(jì)(論文)摘要電表是我國(guó)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(fèi)率、自動(dòng)抄表等產(chǎn)品的優(yōu)勢(shì)突顯,且已經(jīng)逐步成為電
2、表發(fā)展的主流。智能電表具有數(shù)據(jù)的保護(hù),報(bào)警功能,斷電的顯示,負(fù)荷的控制,防竊電功能,遠(yuǎn)程抄表系統(tǒng)等功能,從計(jì)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(zhǎng)期使用的機(jī)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(hù)中的使用。本文主要應(yīng)用IC卡單元,89C51單片機(jī),LED顯示器等各個(gè)單元來(lái)完成費(fèi)率的計(jì)算,數(shù)據(jù)的顯示,報(bào)警,使電表實(shí)現(xiàn)智能化。并根據(jù)階梯電價(jià)計(jì)算出卡內(nèi)電費(fèi)剩余等情況,自動(dòng)報(bào)警功能用蜂鳴器進(jìn)行模擬,并通過(guò)四個(gè)鍵盤(pán)實(shí)現(xiàn)顯示的切換以及電價(jià)的調(diào)整功能,IC卡采用西門(mén)子公司的S
