摘要随着航空模型的发展，特别是无线电遥控模型飞机的日臻完善，航空模型的用途越来越广泛。本文主要研究了基于单片机的遥控直升飞机控制，以STC89C51作为核心部件进行逻辑控制及信号产生，实现了红外远程遥控直升机的目的。论文首先介绍了单片机的基本理论，然后对软件设计中所涉及的红外遥控发射、接收、调速等单元的设计流程及工作原理进行了详细的说明，并阐述了遥控直升飞机的飞行原理。由于飞机配件的选择及组装是本次设计的重要内容之一，因此文中对涉及到的电机、舵机、螺旋桨、锂电池等飞机主要配件及组装注意事项进行了重点讲解。最后通过对软硬件的反复调试，完成直升机的装机和控制系统设计，达到设计要求，实现对遥控直升飞机平衡、上升、下降、左转、右转等简单的控制。该遥控直升机具有接收信号灵敏，控制简单等优点。关键词：遥控直升机；单片机；汇编语言；红外遥控AbstractWiththedevelopmentofaviationmodels,especiallytheradio-controlledmodelairplanesarebecomingperfection,themodelairplaneisgettingmoresophisticatedandmorewidelyused.Inthispaper,themicrocontroller-basedremotecontrolhelicopterisresearched.IttakesSTC89C51asthecorecomponentstohavethelogiccontrolandgeneratesignals,inordertoachievethepurposeoftheinfraredremotecontrolhelicopter.First,thearticleintroducesthebasictheoryofthemicrocontroller;thenillustratesthedesigningprocessandworkingprinciplesofinfraredremotecontroltransmitter,receiver,andspeedcontrolunitinvolvedinsoftwaredesign;andexpoundstheflighttheoryofremotecontrolhelicopter.Becausetheselectionandassemblyofaircraftpartsareoneoftheimportantpartsofthisdesign,thispaperwillpayattentiontoissuesofmotors,steeringgear,propellers,lithiumandotheraircraftinvolvedinthemainpartsandassembly.Finally,aftertherepeatedlytestingofthehardwareandsoftware,thispaperwillcompletetheinstallmentandcontrolsystemdesignofthehelicopter,meetthedesignrequirements,toachievethebalance,up,down,turnleft,turnrightandsomesimplecontroloftheremotecontrolhelicopter.Theremotecontrolhelicopterhasadvantagesofreceivedsignalsensitivelyandcontrolledsimply.Keywords:remotecontrolhelicopter;microcontroller;assemblylanguage;infraredremotecontrolPAGE\*MERGEFORMAT46目录TOC\o"1-2"\h\z\uHYPERLINK\l"_Toc327949152"第1章概述PAGEREF_Toc327949152\h1HYPERLINK\l"_Toc327949153"1.1课题研究的背景和意义PAGEREF_Toc327949153\h1HYPERLINK\l"_Toc327949154"1.2国内外航模的发展状况PAGEREF_Toc327949154\h1HYPERLINK\l"_Toc327949155"1.3论文主要内容PAGEREF_Toc327949155\h3HYPERLINK\l"_Toc327949156"第2章
