ABSTRACT摘要摘要无线遥控技术作为本世纪最有发展前景的信息技术之一，已经得到业界的高度重视。该技术利用无线电方式进行非接触双向通信，可以自动识别目标对象并获取相关数据，具有精度高、适应环境能力强、抗干扰强、操作快捷等许多优点。无线电遥控器是利用无线电信号对远方的各种机构进行控制的遥控设备，本文针对拥有多种家用电器的现代化家庭，设计了一套能够控制八路用电器的无线遥控开关。并对该系统的组成结构和工作原理进行了详细的说明。针对于所需要的设计要求，我主要采用了2262\2272与STC89C52RC和继电器的搭配，设计出315MHz的无线电控制模块，8个开关可分别对8路进行独立控制，并且利用USB接口提供所需要的电压的方法更加能够简单方便的演示所需要的结果。该无线遥控开关电路可在中短距离（≤30米）内，无需对准用电器按一按遥控器按钮，即可实现多路遥控电源电路接通与断开的目的，不仅适用于一般家庭，而且也适合于各大宾馆、饭店、豪华别墅等场所使用。经过试验验证，该无线遥控开关操作方便，工作可靠，符合设计要求。研究成果对促进家居电器的智能化具有重要意义。关键词：STC89C52RC无线电遥控ABSTRACTWirelessremotecontroltechnology,asoneofthemostpromisinginformationtechnologyinthiscentury,hasbeenattachedgreatimportancetotheindustry.Thetechnologyusingnon-contacttwo-waycommunicationintheformofradiocanautomaticallyidentifythetargetobjectandgettherelevantdata,hashighprecision,toadapttotheenvironmentabilityisstrong,stronganti-interference,quickoperationandmanyotheradvantages.Radioremotecontrolusingradiosignalstothedistanceofvariousinstitutionstocontrolremotecontrolequipment,thisarticleinviewofthemodernfamilyhasavarietyofhouseholdappliances,designasetofcancontroleight-wayuseappliances,wirelessremotecontrolswitch.Andthecompositionofthesystemstructureandworkingprincipleareexplainedindetail.Fortherequireddesignrequirements,Imainlyadopted2262\2272withSTC89C52RCandrelaycollocation,designa315MHZradiocontrolmodule,eightswitchcanbeanindependentcontrolofeightroadrespectively,andthemethodofusingUSBinterfaceprovidesthevoltageneededtobemoresimpleandconvenientdemorequiredresults.Inthewirelessremotecontrolswitchcircuitcanbeshort(30meters)orless,withouthavingtouseappliancesaccordingtoapressbutton,canrealizemulti-channelremotecontrolpowercircuitonandoff,thepurposeofnotonlyapplytotheaveragehousehold,butalsosuitableforthemajorhotels,restaurants,luxuryvillasandotherplacestouse.Aftertest,thewirelessremotecontrolswitchiseasytooperate,reliablework,complywiththedesignrequirements.Researchresultstopromotetheintelligenthouseholdappliancesisofgreatsignificance.Keywords:STC89C52RCwire
