汽车轮胎压力监测系统设计.docx

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AbstractAlongwiththedevelopmentofsocialeconomyandscienceandtechnologyhighwaytraffichasbecomethelifebloodofnationaleconomyandtherelationshipbetweensocialandeconomicdevelopmentofimportantsystembuttheresultingtrafficaccidentstothehumanlifesecurityandeconomicdevelopmenthascausedgreatlosses.FlatTireisamajorcauseoftrafficaccidentkeepthestandardTirePressureisthekeytopreventblowoutTirePressureMonitoringSystemTPMS(TirePressureMonitoringSystem)isthusarisesatthehistoricmomentofsafeguardSysteminacar.Tirepressuremonitoringsystemismainlyusedforthecarofautomobiletirepressureandtemperatureintheprocessofreal-timedetectionandalarmwhenabnormalstatethusensuringthedrivingsafety.Thepurposeofthisresearchistodevelopakindofappliedtomotorvehicletirepressureandtemperaturemonitoringsystem.Thispaperpresentsatemperatureoftirepressuremonitoringsystembasedonwirelesstechnology.Integrateduseofthehardwaredesignofdetectiontechnologymicro-controllertechnologyandwirelesscommunicationtechnologythelaunchmodulecanreal-timetirepressureandtemperatureparametersdetectionprocessingandusewirelesswaytotransmitdataafterprocessingtoreceivingmodule;Receivingmodulecancheckdataanddisplaytheresultstoinformthedriverofeachtire.Thissystemadoptedtheeffectiveenergysavingmea
