基于单片机的智能语音广告牌控制系统摘要在信息时代之下，使得传统的静态广告窗在日益白热化的市场竞争中竞争力越来越弱，广告进入自动控制时代已经是一种必然发展趋势，在本文中所具体设计出来的是一种智能滚动式语音广告窗，这种广告窗主要是通过单片机来进行控制，随之成为一种静态广告画面转换的自动控制系统。该系统能够实现成百上千的广告画面循环滚动显示，同时每一副广告画面都对应一段语音信息，能够智能识别是否有人浏览，随后播放与滚动广告画面对应的每一个语音信息。本设计由单片机STC89C52芯片和专用时钟芯片DS1302、热释红外传感器、WT588语音模块和LCD1602显示屏组成，加上其他外围电路，组成的一个实用的单片机多功能广告控制系统。关键词：单片机，时钟芯片，热释红外感器，语音模块，LCD显示屏AbstractTheadventoftheinformationsociety,thetraditionalstaticadvertisingwindowinthefiercecompetitioninthemarketisinsufficient,theadsintotheautomaticcontrolerahasbecomeinevitable,thedesignoftheintelligentspeechadvertisementwindowisrollingautomaticcontrolsystemconsistsofastaticadvertisementpictureconversionMCUcontrol,thesystemcanbethenumberofadvertisingpicturescircularscrolling,andeachadvertisementpicturecorrespondstoavoicemessage,canidentifywhethertheintelligentvoiceinformationpeoplewatchandthenplaywithrollingadvertisementpicturecorresponding.ThisdesignbySTC89C52chipandclockchipDS1302,pyroelectricinfraredsensor,WT588voicemoduleandLCD1602display,andotherperipheralcircuits,apracticalsinglechipmulti-functioncontrolsystemcomposedofadvertising.Keywords:Singlechip,clockchip,pyroelectricinfraredsensor,voicemodule,LCDdisplay目录第一章绪论.................................................................................................................................41.1课题研究的背景和意义........................................................................................................41.2智能广告控制系统的功能....................................................................................................4第二章设计总体方案论证.............................................................................................................52.1.智能广告控制系统设计思路................................................................................................52.1.1单片机的方案选择.........................................................................................................52.1.2数字时钟的方案选择.....................................................................................................62.1.3人体感应方案.................................................................................................................62.1.4显示电路的方案选择.....................................................................................................82.1.5语音模块的方案选择...................................................................................................102.1.6步进电机驱动方案........................................................................................................132.2.智能广告控制系统方案......................................................................................................13第三章系统硬件设计.................................................................................................................153.1单片机设计方案...................................................................................................................153.2时钟日历芯片设计...............
