智能温控风扇的设计I郑州科技学院专科毕业设计(论文)题目智能温控风扇的设计学生姓名专业班级学号所在系指导教师完成时间2012年4月1日智能温控风扇的设计II智能温控风扇的设计摘要基于检测技术和单片机控制技术,设计了一种智能温控调速风扇。阐述了智能温控调速风扇的工作原理、硬件设计、软件实现的过程。系统原理简单,工作稳定,成本低,具有一定的节能效果。通过单片机的控制我们实现了电风扇的主要功能:当按下开关键时,系统初始化默认的设定温度为25度,如果外界温度高于设定温度电风扇进行运转,如果外界温度高于低于设定温度则风页不转动,同时显示外界的温度。可以设置所需的温度,并同时显示所设定的温度,同时按加减键退出设定功能。电风扇的自动控制,让电风扇这一家用电器变的更智能化。克服了普通电风扇无法根据外界温度自动调节转速困难。智能电风扇的设计具有重要的现实意义。关键词AT89C52/温度传感器/直流电机/模拟风扇智能温控风扇的设计IIIEsignofintelligenttemperaturecontrolfanABSTRACTBaseddetectionandsingle-chipcontroltechnology,thedesignofasmarttemperaturecontrolfanspeed.Explainssmarttemperaturecontrolfanspeedcontrolworks,hardwaredesign,softwareimplementationprocess.Systemissimple,stable,lowcost,hasacertainenergy-savingeffect.Controlledbythemicrocontrollertoachieveafanofourmainfunctions:Whenyoupressthekeytoopenthesysteminitializethedefaultsettemperatureis25degrees,iftheoutsidetemperatureisabovethesettemperatureforfanoperation,iftheoutsidetemperatureishighbelowthesettemperatureinthewinddoesnotturnthepage,displayingtheoutsidetemperature.Youcansetthedesiredtemperature,andalsoshowsthesettemperature,presstheplusorminuskeytoexitthesettingmode.Automaticfancontrol,sofansofthehomeappliancesbecomemoreintelligent.Unabletoovercometheordinaryfanspeedautomaticallyadjustedaccordingtooutsidetemperaturedifficult.Smartfandesignhasimportantpracticalsignificance.KEYWORDSAT89C52,temperaturesensor,D.C.electricmachine,Simulationoffan.智能温控风扇的设计目录中文摘要.......................................................................................................Ⅰ英文摘要.......................................................................................................Ⅱ1绪论.........................................................................................................31.1引言..................................................................................................31.2发展现状与应用领域.....................................................................32整体方案的设计.....................................................................................52.1系统整体设计..................................................................................52.2方案论证..........................................................................................52.3温度传感器的选择方案.................................................................52.4控制核心的选择..............................................................................62.3显示电路的选择..............................................................................72.4调速方式的选择..............................................................................72.5控制执行部件的选择.....................................................................83主要原件的介绍.....................................................................................93.1温度传感器......................................................................................93.1.1温度传感器的种类和选择...........................................................................93.1.2DS18B20的工作原理及其单片机的接口电路..........................................93.2单片机............................................................................................113.2.1单片机的种类及选择.................................................................................113.2.2AT89C52单片机简介...............................................................................133.2.3AT89C52的性能特点和芯片引脚图..........................................................153.3直流电机........................................................................................164硬件设计...............................................................................................194.1开关复位电路................................................................................194.2数码管显示电路............................................................................194.3温度采集电路................................................................................204.4风扇电机驱动与调速电路...........................................................215软件设计...............................................................................................236系统调试...............................................................................................256.1系统存在的不足及展望...............................................................256.2调试过程中遇到的故障及解决方法...........................................25结束语.........................................................................................................26致谢.........................................................................................................27智能温控风扇的设计参考文献.....................................................................................................28附录1:电路总图..................................................................................29附录2:实物图......................................................................................30附录3:源程序......................................................................................31附录4:温控风扇清单..........................................................................35智能温控风扇的设计31绪论1.1引言生活中,我们经常会使用一些与温度有关的
