智能停车系统设计毕业论文

长春工业大学人文信息学院毕业设计（论文）I摘要自动停车系统是一种通过探测车辆周围环境信息来找到合适的停车位，从而控制车辆的转向、速度，使得车辆能够自主驶入停车位的系统。相比于人工停车事故率高、传统倒车雷达智能度低，自动停车系统提高了车辆的智能化水平和安全性，进一步降低了新手司机驾驶车辆的难度，也为将来实现车辆的自动驾驶打下基础。一个有效的智能停车系统，不仅能帮助驾驶者快速、安全地完成停车操作，从而减轻驾驶员负担，减少交通事故，而且能够有效提高汽车的智能化程度，增加汽车的附加值，从而带来巨大的经济效益。使用AT89C52单片机作为小车的主控制器，在该控制器基础上，添加了光电避障电路、测速电路、光源引导电路和电机驱动电路，从而实现了智能停车系统设计。该系统结构简单、成本低，并在实验室中取得了预期的效果，能够使小车进入指定的停车位。关键词：单片机传感器电动转向自动停车长春工业大学人文信息学院毕业设计（论文）IIAbstractAutomaticparkingsystemisakindofthroughthedetectionvehicleenvironmentinformationtofindparkingSpaces,soastocontrolthevehicle'ssteering,speed,makesthevehicletoindependentintoparkingSpacessystem.Comparedtoartificialparkingaccidentrateishigh,thetraditionalreversingradarintelligencedegreeislow,automaticparkingsystemimprovestheleveloftheintelligentvehicleandsafety,furtherreducethenovicedriverdrivingthevehicle'sdifficulty,alsoforthefutureofthevehicletorealizeautomaticdrivetolaythefoundation.Aneffectiveintelligentparkingsystem,notonlycanhelpdriversquicklyandsafelycompleteparkingoperation,soastolightentheburden,reducethenumberoftrafficaccidents,butalsocaneffectivelyimprovethecarintelligentdegree,increasetheaddedvalueofcar,soastobringhugeeconomicbenefits.UseofAT89C52singlechipmicrocomputerasmaincontrollerofthecar,inthecontrollerbasis,addthephotoelectricobstacleavoidancecircuit,speedcircuit,lightguidecircuitandmotordrivecircuit,andthusrealizestheintelligentparkingsystemdesign.Thesystemstructureissimple,thecostislow,andinthelabhasachievedexpectedeffect,canmakethecarintothedesignatedparkingspace.Keywords：SCMsensorElectricsteeringautomaticparking长春工业大学人文信息学院毕业设计（论文）III目录第1章概述........................................................................................................-1-1.1智能停车的背景及意义...............................................................................-1-1.1.1引言.......................................................................................................-1-1.1.2背景及意义...........................................................................................-1-1.2单片机发展综述...........................................................................................-3-第2章方案选型设计............................................................................................-7-2.1题目分析.......................................................................................................-7-2.2引导方案设计...............................................................................................-7-2.2.1引导小车传感器选择...........................................................................-7-2.2.2发现车库传感器选择...........................................................................-8-2.3避障电路的选择.........................................................................................-10-2.4车库停车电路的选择.................................................................................-12-2.5显示器的选择.............................................................................................-12-2.6电机的选择.................................................................................................-13-2.7驱动电机电路的选择.................................................................................-14-第3章智能停车系统设计..................................................................................-16-3.1设计原理.....................................................................................................-16-3.2单片机最小系统.........................................................................................-17-3.3红外寻迹电路.............................................................................................-19-3.4红外避障电路.............................................................................................-20-3.5光源检测电路.............................................................................................-23-3.6显示电路.....................................................................................................-24-3.7电机驱动电路.............................................................................................-26-第4章智能停车系统程序设计..........................................................................-29-长春工业大学人文信息学院毕业设计（论文）IV4.1程序.............................................................................................................-29-4.1.1主程序流程图.....................................................................................-29-4.2程序设计.....................................................................................................-30-4.2.1检查光源程序.....................................................................................-30-4.2.2避障程序.............................................................................................-30-4.2.3入库程序.............................................................................................-31-4.2.4显示程序.............................................................................................-31-总结......................................................................................................................-33-致谢...........................
