-基于单片机的遥控系统设计

1摘要随着通信技术的日益发展，电源的控制从以前单一的有线开关控制方式，逐步转变到有线和无线等多种控制结合的方式。因此利用无线电技术开发一种有效、节能、便捷的电源控制系统是很有必要的。论文介绍了一种无线电源控制系统的研究与设计，系统采用AT89C2051型单片机控制，利用RS232C串口，MAX813L看门狗计数器，由TDQ3型的高频调谐器和TA7680组成的中频放大、同步检波电路，实现了定时发射无线电波来控制电源的开关。论文首先介绍了无线遥控的基本理论和发展应用，接着进G15904系统的G11840G1226设计，G3324G3837线发射电路的设计中，通G17819设计G13546G11733电路、无线发射G8181G3371、G3837线的设计来实现无线电G3324单片机中的G13546G11733与发射G2163能G727G3324无线接G6922电路中，通G17819设计接G6922电路、无线接G6922电源电路、G16311G11733电路、G20549G2172电路、G3278G5589G13499电器的应用来实现无线电信G2507的接G6922与G16311G11733，来控制电源的开关G2163能。G9994G2530进G15904系统的G17731G1226设计，通G17819研究设计发射G18108G2010和接G6922G18108G2010的G8981G12255G3282与G12255G5219，来实现G17731G1226G3324G11840G1226G5415中的应用，实现G1866G2163能。G7380G2530进G15904系统G6251G5190G6212的设计，通G17819研究一G1135G5190G6212源的G2419理，来了G16311G4439G1216的G10317G5627，G5194G3324系统中G1823G7393G2520种G5190G6212，G1363系统的G4445G1852G5627、G12295定G5627G7368高。G3G3关键词无线电G72789C2051单片机G727电源控制G3G3G3G3G3G3G3G3G3G3G3G32ABSTRACTALONGWITHCOMMUNICATIONFLOURISHINGMOREANDMOREDAILY,THEPOWERSOURCECONTROLFROMBEFORESOLEWIREDSWITCHCONTROLMODE,TRANSFORMEDGRADUALLYTOWIREDANDWIRELESSANDSOONMANYKINDSOFCONTROLUNIONWAYTHEREFOREUSESTHERADIOTECHNICALDEVELOPMENTONEKINDEFFECTIVE,THEENERGYCONSERVATION,THECONVENIENTPOWERSOURCECONTROLSYSTEMHASTHENECESSITYVERYMUCHTHEPAPERINTRODUCEDONEKINDOFWIRELESSPOWERSOURCECONTROLSYSTEMRESEARCHANDTHEDESIGN,THESYSTEMUSESAT89C2051MONOLITHICINTEGRATEDCIRCUITCONTROL,USESTHERS232CSERIALPORT,THEMAX813LWATCHDOGCOUNTER,ISCOMPOSEDTHESUPERSONICAMPLIFICATION,THESYNCHRONIZATIONDETECTINGCIRCUITBYTHETDQ3HIGHFREQUENCYTUNERANDTA7680,REALIZEDHASFIXEDTIMELAUNCHEDTHERADIOWAVETOCONTROLTHEPOWERSOURCETHESWITCHTHEPAPERFIRSTINTRODUCEDTHEWIRELESSREMOTECONTROLELEMENTARYTHEORYANDTHEDEVELOPMENTAPPLICATION,THENCARRYONTHESYSTEMTHEHARDWAREDESIGN,INTHEANTENNATRANSMISSIONCIRCUITDESIGN,THROUGHTHEDESIGNCODEELECTRICCIRCUIT,THEWIRELESSLAUNCHMODULE,THEANTENNADESIGNREALIZESRADIOINTHEMONOLITHICINTEGRATEDCIRCUITCODEANDTHELAUNCHFUNCTIONINTHEWIRELESSACCEPTINGCIRCUIT,THROUGHTHEDESIGNACCEPTINGCIRCUIT,THEWIRELESSRECEIVEPOWERCIRCUIT,DECODESTHEELECTRICCIRCUIT,ACTUATESTHEELECTRICCIRCUIT,THESOLIDSTATERELAYAPPLICATIONTOREALIZETHERADIOSIGNALRECEIVEANDTHEDECODING,CONTROLSTHEPOWERSOURCETHESWITCHFUNCTIONTHENCARRIESONTHESYSTEMTHESOFTWAREDESIGN,THROUGHTHERESEARCHDESIGNLAUNCHPARTANDTHERECEIVEPARTFLOWCHARTANDTHEPROCEDURE,REALIZESTHESOFTWAREINTHEMIDDLEOFHARDWAREAPPLICATION,REALIZESITSFUNCTIONFINALLYCARRIESONTHESYSTEMANTIJAMMINGTHEDESIGN,THROUGHSTUDIESSOMENOISESOURCESTHEPRINCIPLE,UNDERSTOODTHEIRCHARACTERISTIC,ANDOVERCOMESEACHKINDOFDISTURBANCEINTHESYSTEM,CAUSESTHESYSTEMTHESECURITY,THESTABILITYTOBEHIGHERKEYWORDSRADIOAT89C2051MONOLITHICINTEGRATEDCIRCUITPOWERSOURCEA1A2A3目录引言1第一章硬件电路设计21G171无线发射电路的设计G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G2582G31G171G171G13546G11733电路G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G2582G31G171G172无线发射G8181G3371G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G2583G31G171G173G3837线的设计G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G2583G31G172无线接G6922电路的设计G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G2583G31G172G171无线接G6922电源电路G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G2583G31G172G172G20549G2172电路G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G2585G31G172G173G16311G11733电路G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G2586G3第二章系统的软件设计2G171G17731G1226组成G2462结G7512G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G2589G32G171G171发射G18108G2010G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G2589G32G171G172接G6922G18108G2010G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G717G719G32G172G14270定G1053G13546G11733的G17731G1226实现G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G25811G3第三章系统抗干扰设计133G171G5190G6212源G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G25813G33G171G171电源G5190G6212G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G25813G33G171G172数G4395电路的G5190G6212G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G25813G33G172G17767G1849、G17767G1998通G17959G5190G6212的G6245制G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G25813G33G172G171电源与电G13605G5190G6212的G6245制G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G258G2581G23G33G172G172G3332线系统G5190G6212的G6245制G258G258G258G258G258G
