夏季车辆自动喷淋降温系统张一楠PAGE\*MERGEFORMAT6摘要随着汽车的普及程度提高，车辆安全隐患逐渐被人们重视，其中高温条件下车体和乘车人员的安全隐患成为一种发生频率较高却重视度不够的隐患。本文设计了一种基于51单片机应用的夏季车辆自动喷淋降温系统。本系统由五个模块组成，分别是温湿度检测模块、红外检测模块、显示模块、蓝牙模块和喷淋模块。红外检测模块可以实时检测特定空间内是否有车辆停放，当有车辆停放时，温湿度模块通过传感器检测环境的温度和湿度，并由显示模块显示数据，由蓝牙模块在一定范围内将数据传送给单片机进行判断，若实时温度高于阈值，则启动喷淋模块降温；当没有车辆停放时，不启动其他模块。经过多次调试，逐一实现了夏季车辆自动喷淋降温系统的功能，并且在实际应用中，本系统具备环保性、智能性、安全性、舒适性，能为人们的生活带来更多的方便与快捷。关键词：喷淋降温系统；单片机；温湿度检测；红外检测；蓝牙AbstractWiththeincreasingpopularityofautomobiles,vehiclesafetyhazardshavegraduallybeenpaidattentionto.Amongthem,thesafetyhazardsofcarbodiesandpassengersathightemperatureshavebecomeahiddenhazardwithahighfrequencybutinsufficientattention.Thispaperdesignsanautomaticspraycoolingsystemforvehiclesinsummerbasedontheapplicationof51singlechipmicrocomputer.Thecontrolsystemconsistsoffivemodules:temperatureandhumiditymodule,infrareddetectionmodule,module,Bluetoothmodule,spraymodule.Theinfrareddetectionmodulecandetectwhethertherearevehiclesparkedinaspecificspaceinrealtime.Whenavehicleisparked,thetemperatureandhumiditymoduledetectsthetemperatureandhumidityoftheenvironmentthroughthesensor,andthedisplaymoduledisplaysthedata,andtheBluetoothmoduletransmitsthedatatothesinglechipmicrocomputerforjudgmentwithinacertainrange.Ifthereal-timetemperatureishigherthanthethreshold,theMCUstartsthespraymoduletocooldown.Whennovehicleisparked,othermodulesarenotactivated.Aftermanydebugging,thefunctionsoftheautomaticvehiclecoolingsysteminsummerwererealizedonebyone.Whenappliedtotheactualautomobilecoolingsystem,itwillimprovetheenvironmentalprotection,intelligence,safetyandcomfortofthevehicle,andbringmoreconvenienceandspeedtopeople'slife.Keywords:Spraycoolingsystem;Singlechipmicrocomputer;Temperatureandhumiditydetection;Infrareddetection;Bluetoothmodule目录摘要HYPERLINK\l"_Toc483223928"IAbstractHYPERLINK\l"_Toc483223928"IITOC\o"1-1"\h\z\t"标题2,2,标题3,3,附录,1"HYPERLINK\l"_Toc39587355"第1章引言PAGEREF_Toc39587355\h1HYPERLINK\l"_Toc39587356"1.1国内外研究现状PAGEREF_Toc39587356\
