20届毕业生毕业论文题目:基于单片机的智能台灯设计院系名称：信息科学与工程学院专业班级：电子信息科学与技术学生姓名：学号：指导教师：教师职称：20年6月日II摘要社会在不断进步，人类在不断追求，市场在不断变化，高科技应用含量决定着产品发展的新趋势和前景，智能化技术在电子产品领域的应用意义深远。随着电子产品的快速发展，家用电器也越来越偏向智能化，已经应用于实际中的有智能洗衣机，智能电饭锅，智能电磁炉等，而所用的智能化家用电器都用一个共同的特点，都是利用单片机作为中央控制单元。结合了单片机的智能家用电器和普通家用电器相比，功能上更强，使用更方便，安全可靠性也更高，最重要的是更节省电能，提高了家用电器的品质。智能台灯以专门感应人体红外信号的热释电红外传感器为基础，以BISS0001信号处理电路，利用单片机进行处理，以达到便于控制的目的。当房间亮度不够时，且有人在附近时，台灯便会自动点亮，省去了黑暗中摸开关麻烦；当学习时由于靠桌面太近，造成坐姿不正，系统就会提示，以纠正坐姿，防止近视；学习太累了时，趴在桌子上睡会儿时，台灯就会自动熄灭；当无人在时，系统也会使台灯自动熄灭，以达到节省能源的目的。关键词：智能台灯BISS0001单片机AT89C51IIITitle：IntelligentdesklampdesignBasedonMCUAbstractSocialprogressandhumanintheconstantpursuit,themarketinaconstantlychanging,high-techapplicationcontentdecidedthenewtrendofdevelopmentoftheproductandprospects,intelligenttechnologyintheelectronicproductsinthefieldsofapplicationofmeaning.Withtherapiddevelopmentofelectronicproducts,householdappliances,hasmoreandmoreisalsoturntointelligentappliedinpracticeofintelligentwashingmachine,intelligentelectric,intelligentinductioncookeretc,andtheintelligenthouseholdappliancesareusedwithacommoncharacteristics,areusingsinglechipmicrocomputerasthecentralcontrolunit.CombinedwithMCUintelligenthouseholdappliancesandordinaryhouseholdappliances,strongerthanonthefunction,usemoreconvenient,safetyreliabilityalsohigher,themostimportantisthemoretosaveelectricenergy,improvethequalityofthehouseholdappliances.Intelligencedesklampforspecificallyinductionhumanheat-releasinginfraredsignalbasedoninfraredsensors,BISS0001signalprocessingcircuit,usingsinglechipcomputerprocessing,inordertoachievethepurposeofeasycontrol.Whentheroomandsomeonewheninsufficientbrightnessaround,desklampwillbelighted,tellthedarknesstouchswitchtrouble;Whenlearningonthedesktopistooclose,duetocausespostureisnotstraight,thesystemwillhint,inordertocorrectposture,preventingmyopia;Learningtootired,sleeponhisdesklampwhen,itwillautomaticallyout;Whennoonein,thesystemalsocanmakedesklampextinguishes,inordertoachieveautomaticsaveenergypurposesKeywords：IntelligencedesklampBISS0001microcontrollerAT89C51IV目录摘要...............................................................IIAbstract......................................................................................................................III1绪论..............................................................................................................................11.1智能台灯系统概述..............................................................................................11.2毕业设计内容......................................................................................................22.系统主要器件介绍......................................................................................................42.1AT89C51................................................................................................................42.2BISS0001..............................................................................................................72.3DAC0832................................................................................................................82.474LS138................................................................................................................93.系统组成及电路设计................................................................................................123.1系统组成部分....................................................................................................123.2电路设计部分....................................................................................................134.传感器部分................................................................................................................184.1热释电红外传感器的原理特性.........................................................................184.2热释电红外传感器的工作原理.........................................................................184.3光敏电阻.............................................................................................................195.软件程序设计..........................................................................................................215.1总体程序框图....................................................................................................215.2主程序流程图....................................................................................................21总结及展望....................................................................................................................23致谢................................................................................................................................24参考文献........................................................................................................................25附件..........................................................................................................................2611绪论1.1智能台灯系统概述随着科技的高速发展，各种各样的科技产品、家用电器开始走入人们的生活，这一切都大大地提高了人们的工作效率、改善了人们的生活，现在电器的发展趋势是智能化，这样会使人们使用起来更加方便。随着智能控制理论和人工智能研究的深入，各种更加逼真地模拟人类智能的家用电器会更多地出现，而单片机和智能理论的结合，将来不但更多地改进现行家用电器，而且将会产生全新的家用电器。家用电器因为单片机的加入而走向智能化，并且随着人们生活水平
