青岛理工大学毕业设计（论文）摘要随着人们生活水平的提高和建立绿色城市的向往，音乐喷泉以其独特的魅力和特殊的功能，愈来愈成为休闲娱乐产业中的一项重要产品,音乐喷泉的兴建也越来越多。根据目前音乐喷泉的发展现状，介绍了一个以AT89C51单片机为核心的小型音乐喷泉控制系统。给出了一个简洁的单片机控制电路，分析了输出地址，描述了不同类型的输出电路和输入电路；介绍了从特定构造的喷池中获得决定喷池动作的喷池数据的原理；给出了主程序框图和看门狗子程序。采用程序控制来控制花型。音频信号还影响灯光色彩和灯光光线明暗的变化。从而使灯光色彩、灯光的闪烁和喷泉水姿随音乐节奏而变化。关键词：音乐喷泉；单片机；单片机控制；喷池数据ABSTRACTWiththeimprovementofpeople'slivingstandardandyearnfor1青岛理工大学毕业设计（论文）buildinggreencity,musicfountainismoreandmorepopularforitsuniquecharmandspecialfunctionlargenumbersofmusicfountainisincreasinglybuilt.Accordingtothepresentsituationofmusicfountainnow,controlsystemofminitypemusicFountainbasedonAT89C51SCMwasintroduced．AsuccinctSCMcontrolcircuitwaspre—toobtaindatafromaspecificfountainpool.Waselaborated，whichwillaffectactionsofthep001．Finally,thestructuredrawingofmainprogramandthewatchdogprogramwereputforward.Theflowershapesarecontrolledbyprogramcontrollingorman-madekeystrokecontrollingelectromagneticvalves.Thecolor、thelightandshadeofrayarechangedbymusicalsignals.Sothatthecolor、thelightandshadeofray、thespringformischangedwithmusic’srhythmwhenmusicisplayed．KeyWords:musicfountain；SCM；SCMcontrol；watchdogprogram目录摘要...............................................................................................................................12青岛理工大学毕业设计（论文）ABSTRACT...................................................................................................................2第1章绪论..................................................................................................................41.1课题背景...........................................................................................................41.2音乐喷泉的发展和现状...................................................................................5第2章音乐喷泉控制系统硬件设计...........................................................................62.1控制系统硬件总体设计方案...........................................................................62.2音乐信号的采集...............................................................................................72.2.1音频放大电路的设计.............................................................................72.2.2采样定理.................................................................................................92.3单片机电路.....................................................................................................102.3.1单片机的概述.......................................................................................102.3.2时钟电路的设计...................................................................................112.4AD转换电路...................................................................................................112.4.1ADC0809与单片机89C51的连接.....................................................122.4.2输入电路...............................................................................................132.5潜水泵调速硬件方案设计..................................................
