基于手势和语音控制的智能LED台灯设计——毕业论文

毕业设计(论文)题目：基于手势与语音控制的智能LED台灯设计学院(系)：物理科学与工程技术学院专业：电子科学与技术班级：2011级1班学号：1112270105学生姓名：吴钊华指导教师：陆翔二〇一五年五月I摘要目前，国内外对智能家用电器的研究已经到达了一个飞速发展的阶段，在智能电视、智能空调、智能洗衣机和智能电饭煲等家用电器中，都有不少代表性的产品。而在智能节能LED台灯这方面的研究，却少有代表性的产品，尤其是综合性较强的智能节能LED台灯。在研究原有智能台灯基础上，设计了一种基于手势与语音控制的智能LED台灯。该智能LED台灯的整体控制结构由传感器模块、电源模块、LED矩阵和控制模块构成。传感器模块包括驻极体拾音器、手势传感器模块、人体红外传感器、亮度传感器，LED矩阵包括LED驱动器和高亮暖白光LED，控制模块包括微处理器和语音识别芯片。所有控制信号和传感器信号都会经过主控制器，然后主控制器对输入信号进行分析和处理后，输出控制命令到LED驱动器，LED驱动器驱动高亮暖白光LED发光。该智能LED台灯有两种控制方法，其一为自动模式，其二为人机交互模式；两个模式间能自由切换，具有关机状态记录，开机状态恢复等功能。多传感技术的应用，能减少周围环境的影响，大大提高台灯的稳定性和易用性，使之更实用更智能。该台灯不仅具有更高的使用灵活性和实用性，同时也增加了产品的科技感。该台灯使用的控制方法并不局限于台灯，也可以移植到其他的普通的家庭照明或其他遥控型家用电器中，说明该方法的实用性很高。关键词智能LED台灯手势控制语音控制节能传感器IITheDesignofIntelligentLEDLampbasedonGestureandVoiceControlAbstractAtpresent,theresearchesonintelligenthomeapplianceshavereachedastageofrapiddevelopment,inthesmartTV,smartairconditioning,smartwashingmachinesandintelligentricecookersandotherhouseholdappliances,therearealotofrepresentativeproducts.EnergySmartLEDlampinresearchinthisarea,fewrepresentativeproducts,especiallymoreintegratedintelligentenergy-savingLEDlamp.TheLEDlampwasdesignedbasedontheresearchandtheoriginalsmartlampandintelligentgestureandvoicecontrol.OverallcontrolstructureoftheintelligentLEDlampconsistsofasensormodule,apowersupplymodule,LEDmatrixandthecontrolmodule.Thesensormoduleincludesanelectretmicrophone,gesturesensormodule,thehumanbodyinfrareddetectingsensor,lightsensor,LEDmatrixincludesaLEDdriverandhighlightthewarmwhiteLED,thecontrolmoduleincludesamicroprocessorandavoicerecognitionchip.Allcontrolsignalsandsensorsignalswillgothroughthemaincontroller,thenthemaincontrollerinputsignalanalysisandprocessing,theoutputcontrolcommandstotheLEDdriver,LEDdriverdrivesthehighlightwarmwhiteLEDlight.TheintelligentLEDlamphastwocontrolmethods,onefortheautomaticmode,thesecondforinteractivemode;canfreelyswitchbetweenthetwomodes,withoffrecord,poweredrecovery.Applicationofmulti-sensortechnologycanreducetheimpactonthesurroundingenvironment,greatlyimprovingthelamp'sstabilityandeaseofuse,makingitmorepracticalandmoreintelligent.Thetablelampnotonlyhasahigherflexibilityofuseandpracticality,butalsoincreasedthesenseoftechnologyproducts.Thiscontrolmethodisnotlimitedtotheuseoftablelamptablelampcanalsobeportedtoothernormalhouseholdlightingorotherhouseholdappliancesinremotecontrol,indicatingahighpracticalityofthisapproach.KeywordsgesturecontrolvoicecontrolintelligentLEDlampefficiencysensorIII目录引言.............................................................................................................................................1主要功能和技术参数指标.............................................................................................................2第一章方案设计的比较与论证...................................................................................................31.1主控制器的选择方案........................................................................................................31.2手势识别的选择方案........................................................................................................31.3语音识别的选择方案........................................................................................................41.4人体红外检测的选择方案................................................................................................41.5光照强度采样检测的选择方案........................................................................................41.6LED驱动的选择方案.......................................................................................................51.7主电源的选择方案............................................................................................................5第二章LED台灯的智能控制原理..............................................................................................72.1手势识别与语音识别的实现原理....................................................................................72.1.1手势识别原理.........................................................................................................72.1.2语音识别原理.........................................................................................................72.2智能LED台灯的工作方式...........................................................................................82.2.1自动模式.................................................................................................................82.2.2人机交互模式.........................................................................................................82.3LED的PWM调光原理................................................................................................9第三章LED台灯电路设计........................................................................................................103.1系统硬件结构..................................................................................................................103.2主控制器硬件电路..........................................................................................................103.3手势识别与语音识别硬件电路......................................................................................113.4人体红外检测原理电路....
