基于指纹识别的电子锁系统设计作者姓名:章宏权专业班级:测控技术和仪器2009060101指导教师:李晓丽摘要随着社会的发展和科技的进步，传统的安全防盗系统面临极大的挑战。生物识别技术的蓬勃发展，让人们对于安防系统的设计有了另一种灵感，指纹锁应运而生。可供二次开发的指纹模块已经解决了指纹图像的处理问题，如何实现这种技术的实际应用已经成为急需解决的问题，本设计利用单片机对指纹模块的控制实现了这种技术的应用。设计以指纹传感器对指纹图像的采集为基础，通过单片机控制指纹模块实现对指纹图像的组合处理，系统的各项具体功能皆建立在相应的指纹图像的组合处理基础之上，系统主要实现了指纹模板的录入以及指纹匹配功能。关键词：指纹识别技术；指纹锁；系统设计TheDesignofthesystemofElectroniclockbasedonFingerprintIdentificationAbstract:Withthedevelopmentofthesocietyandtheprogressofscienceandtechnology,Thetraditionalsecuritysystemfacedwithgreatchallenges.WiththevigorousdevelopmentofBiometricIdentificationTechnology,peoplehaveanotherkindofinspirationtodesignthelock，Fingerprintlockarisesattheveryhistoricalmoment.Thefingerprintmoduleforsecondarydevelopmenthassolvedtheproblemofimageprocessing,Theremainingproblemishowtotakeadvantageofthetechnologyinpractice.Thisdesignhasrealizedtheapplication,whichmainlybasedonthecontrolfromMCUtothemoduleoffingerprint.Thefoundationofthisdesignisfingerprintcollection,ThroughthecontrolfromMCUtothemodulecanrealizethecombinationofimageprocessing,basedonthecombinationofimageprocessingcanrealizethevariousfunctionsofthesystem.Themainlyfunctionsofthesystemincludethelandingandmatchingoffingerprinttemplate.Keywords:Fingerprintidentificationtechnology；Fingerprintlock；Systemdesign目录第1章前言..........................................21.1课题研究意义.................................................................21.2国内外指纹锁发展的历史和现状...........31.3本论文的研究内容及结构...............................4第2章整体设计方案................................52.1系统功能设计.................................................................52.2系统总体框架.................................................................6第3章系统硬件电路设计.........................73.1ATmega16单片机外围电路设计............................73.2指纹模块ZFM-206电路................................................83.3ADC键盘电路.......................................................................93.4液晶RX12864ZW电路.......................................................103.5DS1302电路..............................................................................113.6电子锁及相关电路................................................12第4章系统软件设计..............................144.1整体程序流程图.......................................................144.2指纹识别程序设计................................................164.3ADC键盘程序设计.......................................................194.4DS1302程序设计.................................................................214.5液晶RX12864ZW程序设计.............................................21第5章实物制作与调试...........................225.1电路的焊接.......................................................................225.2电路和程序的调试...................................................22结论....................................................23致谢....................................................24参考文献.................................................
