摘要随着社会经济和科学技术的发展,公路交通已经成为关系国民经济命脉和社会、经济发展的重大系统,但随之而来的交通事故给人的生命安全和经济发展造成了重大损失。爆胎是引起交通事故的主要原因,保持标准的车胎气压行驶是防止爆胎的关键,胎压检测系统TPMS(TirePressureMonitoringSystem)是由此应运而生的一项汽车安全防范系统。胎压检测系统主要用于汽车行驶过程中对汽车胎压与温度的实时检测,当出现异常状态时进行报警,从而保障驾乘者的行车安全。本课题主要研究的是一种用于机动车辆上的轮胎压力与温度监控系统。文中提出了一种基于无线技术的轮胎压力与温度监控系统的方案，设计综合运用了检测技术、单片机技术及无线通信技术,其中发射模块能实时检测、处理轮胎的压力和温度参数,并运用无线方式将处理后的数据传输到接收模块;接收模块能校验数据并显示结果,用以告知驾驶员各个轮胎的情况。本系统采用了有效的节能措施,不仅在硬件上选用了具有睡眠功能的芯片,而且在软件设计上通过将判断功能置于发射模块中,减小了系统的发射频率,从而降低了能耗,保证了不会因为更换能源问题而频繁的拆装轮胎,提高了系统的实用性,因而具有广阔的应用前景。关键词:轮胎；无线通信技；抗干扰；节能AbstractAlongwiththedevelopmentofsocialeconomyandscienceandtechnology,highwaytraffichasbecomethelifebloodofnationaleconomyandtherelationshipbetweensocialandeconomicdevelopmentofimportantsystem,buttheresultingtrafficaccidentstothehumanlifesecurityandeconomicdevelopmenthascausedgreatlosses.FlatTireisamajorcauseoftrafficaccident,keepthestandardTirePressureisthekeytopreventblowout,TirePressureMonitoringSystemTPMS(TirePressureMonitoringSystem)isthusarisesatthehistoricmomentofsafeguardSysteminacar.Tirepressuremonitoringsystemismainlyusedforthecarofautomobiletirepressureandtemperatureintheprocessofreal-timedetection,andalarmwhenabnormalstate,thusensuringthedrivingsafety.Thepurposeofthisresearchistodevelopakindofappliedtomotorvehicletirepressureandtemperaturemonitoringsystem.Thispaperpresentsatemperatureoftirepressuremonitoringsystembasedonwirelesstechnology.Integrateduseofthehardwaredesignofdetectiontechnology,micro-controllertechnologyandwirelesscommunicationtechnology,thelaunchmodulecanreal-timetirepressureandtemperatureparametersdetection,processing,andusewirelesswaytotransmitdataafterprocessingtoreceivingmodule;Receivingmodulecancheckdataanddisplaytheresultstoinformthedriverofeachtire.Thissystemadoptedtheeffectiveenergysavingmeasures,notonlyonhardwarechosechipswithsleepfunction,butalsoonthesoftwaredesignoftransmissionmodule,bywilljudgefunctioninreducingthetransmissionfrequencyofthesystem,reducingtheenergyconsumptionandensurethewon'tchangetheenergyproblemandfrequentdisassemblingtire,improvethepracticabilityofthesystem,thushasbroadapplicationprospects.Keywords:tire；wirelesscommunicationtechnologysensor；anti-jamming；saveenergy目录摘要........................................................................IAbstract...................................................................II目录......................................................................III1绪论......................................................................11.1研究背景.............................................................11.2轮胎压力与温度监控系统现状...........................................21.3轮胎压力与温度监控系统研究意义.......................................31.4.2论文的结构安排.................................................42系统总体设计..................................................................
