1、IC卡電表的研究與設(shè)計(jì)摘要隨著我國市場經(jīng)濟(jì)的發(fā)展和金融現(xiàn)代化，現(xiàn)金和各種證件逐漸被各種卡片所取代。IC卡技術(shù)是以計(jì)算機(jī)、通信技術(shù)等現(xiàn)代化科學(xué)技術(shù)為基礎(chǔ)發(fā)展起來的一項(xiàng)新技術(shù)。IC卡是近幾年才出現(xiàn)的新型卡片，它保存的信息可靠、安全，可以高達(dá)幾萬次的讀寫。本文以IC卡預(yù)付費(fèi)電表為例對IC卡在電表中的應(yīng)用進(jìn)行了深入的研究。本文在對傳統(tǒng)電表分析的基礎(chǔ)上，設(shè)計(jì)了IC卡電表預(yù)付費(fèi)的控制系統(tǒng)，該系統(tǒng)采用硬件和軟件相結(jié)合的方法。硬件包括采樣電路，存儲(chǔ)電路，顯示電路，IC卡接口電路和報(bào)警電路。并通過匯編語言編程實(shí)現(xiàn)IC卡在電表終端預(yù)付費(fèi)、電能計(jì)量、數(shù)字顯示和報(bào)警等功能。軟件設(shè)計(jì)是基于
2、硬件設(shè)計(jì)基礎(chǔ)上的程序設(shè)計(jì)過程，具體包括：主程序，插卡中斷子程序，脈沖中斷子程序和顯示子程序等。本文所涉及的主要內(nèi)容有：IC卡基礎(chǔ)知識(shí)的概述、控制系統(tǒng)硬件的選擇、設(shè)計(jì)及功能分析；軟件設(shè)計(jì)部分主要給出了基本程序流程圖和部分具體功能實(shí)現(xiàn)的程序以及簡要的說明。關(guān)鍵詞IC卡;電表;單片機(jī);SLE4442AbstractAlongwiththedevelopmentofmarketeconomyinourcountryandfinancemodernization,cashandmanycertificatesarereplacedgraduallybysomecards.T
