题目:基于单片机的仓库通风控制系统的设计摘要近年来随着社会的不断发展，仓库自动通风控制系统被广泛应用于物品的安全储存仓库通风系统能够对当前仓库的温度进行检测。并且根据实际温度启动风机进行通风降温，当温度降低时关闭风机，停止报警。就目前发展来看，仓库自动通风控制系统必然会成为企业公司货物管理当中不可缺少的一部份。本文基于ATmega128单片机设计了仓库通风控制系统，通过将温度传感器采集的仓库内温度同设定的温度阈值进行比较实现对温度的自动控制，键盘模块可完成阈值温度的调节，仓库内的温度通过数码管显示模块予以显示。经过测试，本设计符合预期要求可将仓库温度控制在设定的范围之内，对于仓库货物的保存具有良好的辅助作用。本文所设计的系统包含主控模块、传感器模块、显示模块以及报警模块等六大组成部分。通过对仓库内部温度的采集和分析，实现通风降温的目的。本设计力争做到准确、实用、操作方便。关键词：通风；传感器；DS18B20；单片机IAbstractInrecentyears,withthecontinuousdevelopmentofsociety,thewarehouseautomaticventilationcontrolsystemhasbeenwidelyusedforthesafestorageofarticles.Thewarehouseventilationsystemiscapableofdetectingthetemperatureofthecurrentwarehouse.Andstartthefantoreducethetemperatureaccordingtotheactualtemperature,turnoffthefanwhenthetemperatureislowered,andstopthealarm.Asfarasthecurrentdevelopmentisconcerned,thewarehouseautomaticventilationcontrolsystemwillinevitablybecomeanindispensablepartofthecompany'scargomanagement.ThispaperdesignsavegetablegreenhousethermostaticcontrolsystembasedonATmega128single-chipmicrocomputer.Bycomparingthetemperatureinthewarehousecollectedbythetemperaturesensorwiththesettemperaturethreshold,thetemperatureisautomaticallycontrolled.Thekeyboardmodulecanadjustthethresholdtemperatureandthetemperatureinthewarehousecanpass.Thedigitaltubedisplaymoduleisdisplayed.Aftertesting,thedesignmeetstheexpectedrequirements,andthewarehousetemperaturecanbecontrolledwithinthesetrange,whichhasagoodauxiliaryeffectonthestorageofwarehousegoods.Thesystemdesignedinthispaperconsistsofsixmajorcomponents:maincontrolmodule,sensormodule,displaymoduleandalarmmodule.Throughthecollectionandanalysisoftheinternaltemperatureofthewarehouse,thepurposeofventilationcoolingisachieved.Thisdesignstrivestobeaccurate,practicalandeasytooperate.Keywords：ventilation;sensor;DS18B20;single-chipmicrocomputerII目录摘要...........................................................................................................................................IAbstract.......................................................................................................................................II目录.........................................................................................................................................III第1章绪论...............................................................................................................................11.1课题研究背景.................................................................................................................................................11.2国内外研究现状.............................................................................................................................................11.3本文组织结构.................................................................................................................................................2第2章系统方案设计......................................................
