1一種基于指紋識別的IC卡門禁系統(tǒng)摘要：討論了一種具有廣泛應(yīng)用前景的指紋IC卡電子門禁系統(tǒng)，介紹了其設(shè)計(jì)方案、系統(tǒng)的總線結(jié)構(gòu)以及單片機(jī)控制局部的軟、硬件實(shí)現(xiàn)。該系統(tǒng)將成熟的指紋生物識別技術(shù)和IC卡技術(shù)緊密結(jié)合在一起，很好地解決了門禁系統(tǒng)中的身份認(rèn)證問題和紙質(zhì)門票帶來的不便，具有很強(qiáng)的靈活性、可靠性和平安性，非常適合于大型風(fēng)景區(qū)等公共場所的門禁管理。關(guān)鍵詞：指紋門禁，智能卡，指紋識別，單片機(jī)對于一票制而需屢次進(jìn)入的地鐵、旅游勝地入口等場合，傳統(tǒng)的紙質(zhì)售票方式已經(jīng)越來越不適用于各部門管理的要求，進(jìn)行計(jì)算機(jī)電子門票管理是社會開展的大勢所趨。其中入口處的身份認(rèn)證是門禁管理的核心工作。在現(xiàn)行的許多計(jì)算機(jī)系統(tǒng)中，用戶的身份認(rèn)證大都使用"用戶ID+密碼"的方法。實(shí)際上，這種方法隱含著密碼易遺忘、可傳遞、易被別人竊盜用等平安問題，同時在入口處需要密碼輸入不適合人流量較大的公共場所，因此在電子門禁中需要一種更為便捷可靠的身份認(rèn)證方案。針對于上述問題，本文討論了一種已研制成功的基于成熟的指紋生物識別技術(shù)和IC卡技術(shù)的電子門禁系統(tǒng)，它具有"人卡合一"的功能，方便可靠地進(jìn)行入口身份認(rèn)證，十分便于部門管理。1門禁系統(tǒng)總體方案泡1.冤1"缺人卡解合一支"的瘋設(shè)計(jì)陰思路公生物評識別惰技術(shù)擊是一柜種根絕據(jù)人源類的路生理輸特征都(指草紋、盾聲音晨、臉寫孔、咬虹膜瞇等)砌來進(jìn)貌行個暈人身然份認(rèn)投證的粗辯識透技術(shù)瞇。近兇年來漠，隨三著信百息產(chǎn)義業(yè)的乳開展羞，生鋤物識鈴別技幼術(shù)在鵝國內(nèi)我外得暴到了浴越來墾越廣膠泛的犁研究清和應(yīng)蒸用。握其中油指紋乞自動鄉(xiāng)識別霧技術(shù)態(tài)是當(dāng)煤今發(fā)測展最漁成熟督的一食種生俘物識勤別技屋術(shù)，敞指紋偶作為愁人體設(shè)生物稱識別倡的一館種方斬式，墓它具狠有以盒下幾鏡個顯善著的哨優(yōu)點(diǎn)躁：(陪1)盼確定范性：售每個緊指紋血在人修六個搭月的椒時候訪形成婆，以餓后終圣身不警會改襪變，吉即使裕被劃惠傷、央燒傷勇，只澇要不志傷及汁真皮乏，都厘不會柿改變演他的殿指紋揉形狀賠。(玉2)瓜唯一洪性：煩兩個著完全洲一樣愛的指賣紋出旅現(xiàn)的戀概率叔非常佳小，訓(xùn)不超識過6宴00田億分軍之一溝。(替3)汽取樣逆簡單升：只嗽需一百個電拳容或怕光學(xué)億的指靠紋采玉集器時就可跑采集登指紋列圖像騰。存看儲數(shù)泡據(jù)少符：指努紋識辛別中練使用淚的模季板只猴是從口指紋蘿圖片診中提座取的奶特征山字節(jié)類，而虛不是望整幅謀指紋截圖片檢，特院征字侵節(jié)的男大小瞎為王30糊0~中40銀0B臨，存資儲量仆相對調(diào)較小混。膨另一深方面席，與友磁卡略相比賞IC遵卡作奇為個閥人指哥紋的歇載體籠又具洗有以久下幾具個優(yōu)慚點(diǎn)：學(xué)(1滲)I宮C卡桂片使辰用壽龜命較循長，環(huán)一般童可反津復(fù)讀僚寫1慌0萬菊次以拐上。碑(2燃)卡統(tǒng)片存毒儲容李量大達(dá)，具急有足術(shù)夠空味間存寧放指憐紋圖常像的搜特征吩數(shù)據(jù)講。(候3)尤加密躲存儲聞卡具吉有邏伐輯加堂密功稼能，吉卡片霧受密擾碼保矮護(hù)，帆可以饑防止示非法煌復(fù)制斧。囑門禁規(guī)系統(tǒng)純將卡攀持有品者的醋指紋體加密觀后存神儲在畫智能驢卡上矩，并爸在智調(diào)能卡圍的讀備寫機(jī)栽具(辣或系蠟統(tǒng)上由)加秤裝指坐紋識毒別系斑統(tǒng)，惠當(dāng)持被卡者荷將卡魂插入駕智能良卡讀沾寫機(jī)蘆具時蘋，讀孝寫機(jī)箏具首賭先將蛙指紋膀信息所讀出抖來并鼓要求步用戶洗比對具指紋職，通青過比畝對卡恒上的記指紋銷和持承卡者臉本人譽(yù)的指減紋就戰(zhàn)可確握定持扛卡者議是否賺為卡蒸的真名正主奴人。擋這樣葉便保梢證了干只有鏈真正寬的卡弄主人味才能階使用警這張窄卡。蠻我們筋將這甲種加仇裝了勇指紋愚識別患系統(tǒng)逆和智謊能卡德讀寫睡機(jī)具侄的門立閘稱克為指列紋I嗓C卡無門閘伏。將籍指紋蠅識別幣技術(shù)氏和智諒能卡拍結(jié)合換起來截，是絡(luò)目前木門禁鏈系統(tǒng)災(zāi)中最龍具有繡前景跌的身善份認(rèn)而證方霧案。頃它不遇但解庫決了讓紙質(zhì)絮門票譽(yù)的身扭份認(rèn)植證難琴題，浪而且錢由于絞實(shí)現(xiàn)道了"牽人卡俘合一駕的"跳計(jì)算紫機(jī)管怎理，稼也為教管理姓者提慨供了滋靈活辯的門怠禁方細(xì)案。西1.拖2娛鬧系統(tǒng)聽組成巖基于紗上述寺設(shè)計(jì)標(biāo)思路悲和一污般的愛實(shí)際套應(yīng)用花要求深，一正般的榜指紋富IC滋卡同門禁怠系統(tǒng)淚由3呢個部掙分組靈成，揪其基翁于單返個入榨口處蜘的總炸體框造圖如蝶圖1兵所示依.門禁管理PC機(jī)門禁管理PC機(jī)單片機(jī)控制系統(tǒng)IC卡讀寫器電動門閘指紋采集校驗(yàn)?zāi)K指紋指紋IC卡圖1指紋IC卡門禁框圖柿(1看)門醬禁管攀理系換統(tǒng)寨憑門禁艷管理宴子系加統(tǒng)完滲成門恢票管屯理和鎖發(fā)卡怨兩項(xiàng)它功能寬。其熱中門踐票管怎理軟綠件實(shí)云現(xiàn)門女票記穗錄、沒查詢枯、統(tǒng)裝計(jì)等鳥管理千任務(wù)漁。所灘謂發(fā)條卡是聞指在管將卡劃片發(fā)庭行給悼用戶手之前碧，需赤要由岸發(fā)卡休機(jī)構(gòu)脊將卡怕片的潮應(yīng)用喝序列杠號、勸密碼秘、允搶許使拌用天言數(shù)等旺根本冶信息童寫入曬用戶川IC旁卡內(nèi)比的這罰一過乒程。竟一般銜來講靈，門前禁管第理P喪C位機(jī)可碌以通亞過兩勢種方霜式實(shí)填現(xiàn)數(shù)肉據(jù)采擱集：破利用躬大容支量I腦C卡抽人工察批量避采集滋或通貓過串爪口互線聯(lián)形臂成的楚低層字電子千門閘拳網(wǎng)絡(luò)龍實(shí)時專地完維成入乖口數(shù)匠據(jù)采悼集。伯對于挎有多曉個入吉口的危門禁父系統(tǒng)帶，如聰大型季的足晚球體奇育場早、有飛多個錢景點(diǎn)浮的大敏型自計(jì)然風(fēng)男景區(qū)送等，睛需要盼在不絨同地糊點(diǎn)，抹安裝要多個奏這樣摘的子恥系統(tǒng)刪。這昌時系繞統(tǒng)需貸要根榨據(jù)地特點(diǎn)間克距離域和用輪戶要貨求，宇將各脈門票略管理觀PC喚機(jī)再凈組成雞一個擁局域般網(wǎng)，弊便于聲各入轟口處徑統(tǒng)一拆管理礙和相文互間咐的數(shù)矩?fù)?jù)傳考輸。聰對于倆大型呢的體姨育場優(yōu)，多剛個入餐口間寧距離消較近輕，采旅用首10嗓M末或幫10趕0M狗的以鍬太網(wǎng)焰較為風(fēng)適宜付。對役于大蹤型的遇自然皆景區(qū)商或地弦鐵，假設(shè)各入扇口處帆距離念較遠(yuǎn)釘且地蛋形復(fù)繞雜，性鋪設(shè)稅電纜隱難，溜采用留基于中模擬海通信鐘方式損的公冷眾電居話網(wǎng)脅〔P稼ST煮N〕崖，就螺根本己可以玻滿足秩系統(tǒng)吵要求捷。狐(2開)指窗紋I余C半卡否病所謂留指紋老IC記卡，購是指畢記錄矩用戶滅生物珠指紋奮特征呼值和閣其它穿信息搖值的戀存儲內(nèi)IC把卡跨。在豈門禁況系統(tǒng)惱中，蛙指紋倦IC籠卡就脈是一津張由閉用戶娛唯一缺持有饞的電什子門覺票。兵用戶戴首次載使用重時，要由I獅C卡喊門閘傅提取釣指紋凱并和貴當(dāng)前俘時間攏一起召寫入艇卡中販，以疼后卡三持有嫂者在錘每次鍋進(jìn)入詠時將護(hù)該卡形插入芝讀卡桂機(jī)，倡隨后仰將手踩指伸攤到指持紋采仍集窗屢口，繡讀卡脊機(jī)便凱會自抗動將角他的內(nèi)指紋右和卡隨上的蝴指紋疲相比騎對，山比對惜成功君那么啟權(quán)動門雪閘放邪行，灑同時倉記錄零進(jìn)入簽的卡搶號、意時間輪等信暫息。趁目前便市場檔上有姻多種斯型號萬的I耳C卡炭，對員于各筍生產(chǎn)吳廠家帝的產(chǎn)待品，傘特點(diǎn)倉也不第盡相趨同。五例如禿美國捎AT籍ME韻L公旦司生買產(chǎn)的做AT湊88楚C泰10首2用加密證存儲罩卡，毀該卡鴿具有挺1k央B裂的加姜密E戴EP意RO茄M萬、2畜B密質(zhì)碼、直4衫次密齡碼比京較機(jī)積會、府10糖萬次貿(mào)讀寫期循環(huán)更能力餅，完撫全可荷滿足版門禁葉系統(tǒng)婚的需溪要。勵(3攻)I糧C卡換電象子門蠶閘指棒紋灶版IC芳卡電肅子門答閘是妄本文片介紹軍的重落點(diǎn)，田它由催指紋葵采集境驗(yàn)證差模塊將、I腰C卡乞讀寫級器、民單片此機(jī)控落制系塘統(tǒng)、緒電動團(tuán)門閘嘆4乖個部喇分組蜘成。援其中救前3脾個部拴分有映機(jī)地單溶于聽門閘催的箱殘?bào)w之隆中，酸共同但形成陵一個談獨(dú)立羞的身歡份驗(yàn)少證和稠出、爭入控遲制終份端。繁它可烈獨(dú)立刻于上雜位計(jì)化算機(jī)并完成派卡片伶第一梢次使衣用時廊用戶政指紋梨提取蒙、寫承入和汪再次顆使用扇時的失身份猾驗(yàn)證絹以及嗓邏輯蚊判斷唉等幾間項(xiàng)基問本操僻作。確1.赴3鼠IC喊卡電鋤子門律閘資IC三卡電繳子門討閘是叉指紋況門禁陪系統(tǒng)奴的核脆心，采在討都論了魔門禁捏系統(tǒng)股設(shè)計(jì)歌思路讀和系娃統(tǒng)組透成后鍵，以晉下將歌對指粒紋I架C卡菠門閘缸各子彩模塊侍的組撿成和悼功能移作進(jìn)因一步灑的介愈紹。酬指紋末采集租校驗(yàn)棕模塊膊挑數(shù)辨字指否紋采店集校相驗(yàn)?zāi)Ｙv塊包摩括一遷個甚35撈mm驚旁×廟35餓mm窗光電拆感應(yīng)途式傳腿感器伐板(濫即采疤集窗獅口O崇pt民ic鉤al宿Un壺it愉)、洪一個猜32而位測CP菜U、然動態(tài)森隨機(jī)階存儲妄器(惰DR俊AM村)、詢閃存簡(F粘la躬sh姓M敏em眠or叛y)畜，可恥編程轎邏輯防器件蟲(P界LD禍)等芬部件亦組成該，其杏結(jié)構(gòu)稻框圖袋如圖腫2所仆示。宅它是許一個交基于詠第三爆方產(chǎn)伐品的賤獨(dú)立溪子系坑統(tǒng)(儀例如妙美國欣AT飯ME旋L-愈Gr洪en偏ob銀le社d報(bào)iv埋is釀io拌n銅公司六的F艇CD嫩4A掀14田系列孔指紋顧傳感津器等景)。價(jià)指紋蝦采集怨校驗(yàn)鎮(zhèn)模塊持可提驢供一舒?zhèn)€R雹S-豈23急2接姜口與鵲單片剃機(jī)進(jìn)熱行聯(lián)爺系，禁在微追處理究器控姻制系禿統(tǒng)的米參與歡下完課成以瞇下兩軌個功蛙能。純首先糕，能味采集鳳完整廊的數(shù)筍字指伙紋圖縫像，肆并從疊中提慣取特少征生義物代妥碼，孩傳輸泳給單斯片機(jī)樣系統(tǒng)巨。其魂次能填夠自過動進(jìn)蠅行指升紋鑒頁定：掌提取撫指紋輔采集啦圖像門特征肢，并佛將該警數(shù)字蕩指紋晉特征侄生物應(yīng)代碼算信息包存儲架在F唱la受sh啦中乎，再溜與預(yù)脊存在叨IC款卡中踩的該腹
