沈阳理工大学学士学位论文PAGE\*MERGEFORMATI摘要随着电子技术的飞速发展，新型大规模遥控集成电路的不断出现，使得遥控技术有了日新月异的发展。遥控装置的中心控制部件已从早期的分立元件、集成电路逐步发展到现在的单片微型计算机，智能化程度大大提高。近年来，遥控技术在工业生产、家用电器、安全保卫以及人们的日常生活中使用越来越广泛。无线电遥控技术的诞生，起源于无线电通信技术，最初的构想是无线电电报技术的建立，真空电子管的发明使得无线电技术的应用和普及很快应用在民用和军用等各个领域。自从爱迪生发明电灯以来，人类对照明电器的开启和关断控制主要使用手动机械开关。随着无线电的发展，从上个世纪60年代开始，相继出现了无线电遥控的小车。本次设计的无线遥控车系统以STC89C52单片机为核心。主要是有发射部分、接收部分和电机控制三部分组成。无线模PT2262制作的发射频率为315MHz的无线波段来发送控制信号，通过无线接收解码芯片PT2272解码，单片机处理PT2272解码后的电平信号对驱动芯片L298进行相应的控制小车的电机动作。发送和接收部分是采用专用的无线编码和解码芯片，实现小车能前进、后退、左转、右转等相关动作。小车操作方便，控制可靠性高，性价比高等优点。关键词：无线遥控；STC89C52单片机；驱动芯片L298PAGE\*MERGEFORMATIVAbstractWiththerapiddevelopmentofelectronictechnology,theappearanceofnewlarge-scaleremotecontrolintegratedcircuits,makeremotecontroltechnologywiththerapiddevelopment.Thecenteroftheremotecontroldevicecontrolunithasbeenfromtheearlydiscretecomponent,integratedcircuitgraduallydevelopedtothepresentsinglechipmicrocomputer,intelligentdegreeisgreatlyincreased.Inrecentyears,remotecontroltechnologyinindustrialproduction,householdappliances,security,andPeople'sDailylifemoreandmorewidelyused.Thebirthofthewirelessremotecontroltechnology,originatedintheradiocommunicationtechnology,theoriginalideaistheestablishmentofradiotelegraphy,theinventionofthevacuumtubetomaketheapplicationandpopularityofradiotechnologyquicklyappliedincivilandmilitaryandotherfields.SinceThomasEdisoninventedelectriclight,humanopenandshutoffthecontroloflightingismainlyusethemanualmechanicalswitch.Withthedevelopmentoftheradio,fromthelastcentury60s,thereappearedthewirelessremotecontrolcar.ThedesignofthewirelessremotecontrolcarsystemwithSTC89C52single-chipmicrocomputerasthecore.Mainlyhaslaunchpart,receivingpartandmotorcontrolofthreeparts.ProducedbythewirelessmodulePT2262emissionfrequencyto315MHzwirelessbandtosendcontrolsignal,throughthewirelessreceivingdecodingchipPT2272decoding,singlechipPT2272levelsignalafterdecodingtocontrolthecorrespondingdrivechipL298motorcar.Sendandreceivepartadoptsspecialwirelessencodinganddecodingc
