基于单片机的打车系统设计和实现 计算机专业VIP专享VIP免费

I摘要随着社会经济的发展，交通运输越来越发达，汽车行业空前发展，人们出行也越来越多，出行方式由之前的步行、自行车改为出租车，因此加快了出租车行业的发展。城市出租车行业的发展，势必方便人们的出行，增强城市的建设。如何计算顾客乘坐出租车里程费用，需要一款智能的打车计费系统，实现智能化，简洁化，准确化的计算乘客打车金额，因此出租车计价器将具有广阔的市场价值。本设计是一款基于单片机的打开计费系统，主要采用单片机结合外围电路模块来实现计费功能。本系统功能强大，有两种计费方法，分为白天和夜晚两种模式，夜晚价格相对较高。同时支持按时间和里程收费，收费方式灵活。同时采用电机来模拟出租车是否载有乘客。当没乘客乘坐时，液晶屏显示时间和日历，电机不工作。当有乘客乘坐后，液晶界面转到计费界面，电机工作，模拟汽车正常行驶。本系统通过按键来设置各个计费价格，包括起步价，超过起步价后每公里价格，以及白天和夜晚价格，且具有掉电保存功能。计价器关系到乘客的经济利益，在实际生活中很有必要，因此本设计的研究价值很高。关键词：计价器；时钟；单片机IIAbstractWiththedevelopmentofsocialeconomy,transportationismoreandmoredeveloped,unprecedenteddevelopmentofautomobileindustry,peopletravelmoreandmore,thewayoftravelfromthepreviouswalk,bicycletotaxi,sothedevelopmentofthetaxiindustry.Thedevelopmentofurbantaxiindustryisboundtofacilitatepeople'stravelandenhancetheconstructionofthecity.Howtocalculatethecostofcustomers'taximileagerequiresanintelligenttaxibillingsystem,whichcanrealizetheintelligent,conciseandaccuratecalculationofpassengers'taxiamount.Therefore,thetaximeterwillhavebroadmarketvalue.Thisdesignisbasedonasinglechipopenbillingsystem,themainuseofsinglechipcombinedwiththeperipheralcircuitmoduletoachievebillingfunction.Thissystemhaspowerfulfunctionsandtwobillingmethods,whicharedividedintodayandnightmodes,andthenightpriceisrelativelyhigh.Atthesametimesupportbytimeandmileagecharges,chargesflexible.Electricmotorsarealsousedtosimulatewhetherataxiiscarryingpassengersornot.Whentherearenopassengers,theLCDscreendisplaysthetimeandcalendar,andthemotordoesnotwork.Whenpassengersareonboard,theLCDinterfaceturnstothebillinginterface,andthemotorworkstosimulatethenormalrunningofthecar.Thesystemcanseteachbillingpricebypressingthebutton,includingthestartingprice,thepriceperkilometerafterexceedingthestartingprice,andthedayandnightprice,andhasthefunctionofpoweroffandsaving.Themeterrelatestotheeconomicinterestsofpassengers,whichisnecessaryinreallife,sotheresearchvalueofthisdesignisveryhigh.Keywords:meter；clock；SCM目录第1章绪论..................................................................................................................11.1选题概述..........................................................................................................11.2单片机概述......................................................................................................1第2章实施方案设计..................................................................................................32.1设计任务要求..................................................................................................32.1.1设计任务..........................................................................................32.1.2设计要求...........................................................................................32.2设计的主要功能..............................................................................................32.3方案的确定...................
