全自动摇篮的设计摘要随着社会经济的发展，人们的生活也都逐渐提高，许多拥有婴幼儿的家庭都希望孩子有个良好的成长环境，但是年青的父母需要同时兼顾宝宝和家庭生活感到非常疲惫，他们需要一个不仅舒适而且具有人工智能的摇篮。智能婴儿摇篮可以提供给宝宝舒适摇晃，又可以通过音乐启发智力发育，使得妈妈们也可腾出手来处理家务或者休息。从而大大的减轻了婴幼儿父母的劳动负担，促进了婴儿的深度睡眠，提高了大人和小孩的睡眠质量，为婴儿的健康成长提供保证。本次毕业设计拟采用单片机作为全自动摇篮的核心控制部件，硬件电路分声控电路、电机驱动、液晶显示模块和人机交互等模块。人机交互是由定时按键和LCD1602组成，摇篮晃动的时间是由按键预置的；LCD1602可以显示计数时间和定时时间。软件部分应用单片机C语言实现了本设计的全部控制功能，包括定时设置、电机驱动、状态显示、音乐播放等。关键字：单片机；声控；电机驱动；定时DesignofAutomaticCradleABSTRACTWiththesocialandeconomicdevelopment，people'slivesarealsograduallyimproved，manyhouseholdswhichhaveinfantchildrenwanttohaveagoodgrowthenvironment，butmanyyoungparentsneednotonlyworkingbutalsotakingcareofthebaby，theyfeelverytiredandlookforwardacomfortableandartificialintelligencecradle．Anintelligentbabycradlecanprovidecomforttothebabyshaking，andinspireintellectualdevelopmentthroughmusic．Thenmomshaveafreetimetodealwithhouseholdchoresandrest．Withtheintelligentcradle，theinfantsburdenofparentswillbereducedgreatly，andsleepqualityofbabyandparentswillbeimproved，andbabypromotesdeepsleepforthehealthygrowth．Thedesignisdiscussedinthispaper，whichintendstousemicro-controllerasthecoreofthecradleautomaticcontrolcomponents，hardwarecircuitofvoicecircuits，motordrives，LCDmodulesandinteractivemodules．Human-computerinteractioniscomposedbythetimingbuttonsandLCD，thecradleofshakingtimeispresetbuttons;LCDcandisplaythecounttimeandregulartime．Softwarepartoftheapplicationmicro-controllerClanguagetoimplementallthecontrolfunctionsofthedesign，includingthetimingsettings，motordrives，statusdisplay，musicplayerandsoon．Keywords:MICROCONTRLLER;VOICE;MOTORDRIVE;TIMED目录1引言........................................................................................................................................11．1研究背景..................................................................................................................11．2目的与意义..............................................................................................................11．3论文结构安排..........................................................................................................22系统原理及单元电路设计....................................................................................................32．1系统原理框图..........................................................................................................32．2声音传感器..............................................................................................................32．3单片机最小系统.......................................................................................................42．3．1STC89C52RC介绍.....................................................................................52．3．2时钟电路....................................................................................................92．3．3复位电路...................................................................................................102．4LCD1602液晶显示模块........................................................................................102．4．1LCD1602介绍..........................................................................................112．5人机交互模块........................................................................................................142．5．1按键电路功能..........................................................................................152．6电机控制模块........................................................................................................162．6．1ULN2003A芯片介绍...............................................................................162．6．24相5线步进电机介绍............................................................................182．7音乐播放模块........................................................................................................182．7．1ISD1820语音芯片介绍............................................................................193软件设计..............................................................................................................................213．1主程序设计............................................................................................................213．2电机驱动控制程序设计........................................................................................213．3定时中断程序设计框图........................................................................................224系统调试..............................................................................................................................23结论..........................................................................................................................................24参考文献..................................................................................................................................25致谢..........................................................................................................................................25附录A系统电路图.................................................................................................................27附录B作品实物图...........................................................
