摘要当今世界，人们在飞速创造财富和发展文明的同时，也带来了许多负面的效应，环保和能源就是其中重要的两个方面。而传统汽车的大量使用，是造成环境污染和不可再生能源巨大消耗的重要因素。电动车以其排放少、噪声低等优点正受到广泛的关注，世界各国都把电动车作为汽车工业的发展方向。因此，对电动车行驶中各项参数的监测是关系到电动车实用化、商品化的关键技术之一，对环境保护和节约能源等方面都具有重要意义。本文采用PHILIPS公司基于ARM7TDMI-S核的LPC2131芯片为微处理器，设计了针对电动车的蓄电池电压、电流、温度和车速信息进行监测，并使用GPRS无线通信技术进行远端数据传送。LPC2131是一个支持实时仿真和跟踪的微处理器，具有流水线技术和低功耗、高性能等特点。在电动车行驶信息检测方面，选用了霍尔和热敏电阻传感器，为数据的准确采集提供了可靠措施。同时在远程端数据传输上，本系统选择了GPRS模块MC55，其尺寸小、重量轻、传输速度快等优势保证了电动车的远程监控。关键词电动车蓄电池LPC2131GPRSAbstractToday'sworld,peoplecreatewealthandrapiddevelopmentofacivilthesametime,alsobroughtmanynegativeeffects,environmentalprotectionandenergycouldbeanimportantontwolevels.Widelyusedintraditionalcarsiscausingenormousenvironmentalpollutionandconsumptionofnon-renewableenergyanimportantfactor.Itsemissionsthanelectricvehicles,andlownoisearewidespreadattention,andeverycountryintheworld'selectriccardevelopmentastheautomotiveindustry.Therefore,theparametersofamovingelectricvehiclemonitoringisrelatedtotheelectricvehiclepractical,commercialoneofthekeytechnologiesforenvironmentalprotectionandenergyconservationareallsoimportant.Inthispaper,basedontheARM7TDMI-SPHILIPScompanyLPC2131chipforthemicroprocessorcore,designedforelectricvehiclebatteryvoltage,current,temperatureandspeedmonitoringinformationandusesGPRSwirelesscommunicationtechnologyforremotedatatransmission.LPC2131isareal-timesimulationandtrackingofthemicroprocessor,withtheassemblylinetechnologyandlowpower,highperformanceandsoon.Trafficinformationdetectioninelectricvehicles,theuseoftheHallandthermistorsensorsforaccuratedatacollectiontoprovideareliablemeasure.Atthesametimedatatransmissionontheremoteside,thesystemselectedtheGPRSmoduleMC55,itssmallsize,lightweight,fasttransmissionofelectriccarsandotheradvantagestoensureremotemonitoring.KeywordselectriccarbatteriesLPC2131GPRS目录摘要..............................................................................................................................IAbstract.......................................................................................................................II第一章绪论...............................................................................................................11.1研究的背景及意义.........................................................................................11.2电动车发展概况............................................................................................21.2.1国外电动车发展情况..........................................................................21.2.2国内电动车发展情况..........................................................................41.2.3电动车发展过程中存在的问题..........................................................61.3远程监控发展概况........................................................................................61.4本文研究的主要内容....................................................................................7第二章远程数据传输方案选择..............
