基于单片机的万能遥控器的设计与实现摘要随着人们对红外线认识的不断提高以及遥控技术的大力推广,红外线遥控器在我们日常生活中使用的频率已经越来越高,我们每天都面临着各种遥控器的选择,有时候很难快速的找到我们需要的那个遥控器,这给我们的日常生活带来了很大的影响。为了让更多的人加深对遥控器的认识,以及更新人们脑海中传统遥控器的概念,并且让人们使用遥控器更加方便,我决定设计一款建立在单片机基础上的,带有学习功能的万能遥控器。本产品设计了三个主要功能,主要有学习功能,解码功能以及遥控功能,遥控部分又可以分为发射和接收两个模块。首先,我会给三个功能按键以及下面的矩阵键盘都存上相应的编码,然后在插入显示屏后还会显示不同的功能以及对应的红外编码。当我们切换到学习功能时,需要按下一个按键并对其进行学习,然后将被学习遥控器中的按键对准此产品,按下被学习遥控器特定功能的按键,会听到蜂鸣器响一声,然后显示器会显示对应的红外编码,学习完成。然后,我们切换到遥控功能,按下遥控功能对应的按键,蜂鸣器会响一声,然后会发现此设备已经完成了原来遥控器的对应功能,学习和发射过程结束。通过对此产品的设计,加深了我对单片机技术的认识,改变了我对红外线技术的认知,通过不断的实验和总结,实现了对发射和接收,解码与编码,学习等功能的设计。而且,显示器可以很直观的显示不同的功能,十分的方便。此外,万能遥控器的实现给很多家庭带来了福音,从此我们可以只使用一款遥控器就可以代替很多家用遥控器的功能,大大提高了工作效率。关键词:单片机;远程遥控;按键;对应功能;编码;1AbstractWiththeimprovementofawarenessofinfraredandthepromotionofremotecontroltechnology,thefrequencyofinfraredremotecontrolusedinourdailylifehasbecomemoreandmorehigh,wefaceavarietyofremotecontrolseveryday,andsometimesitisdifficulttoquicklyfindtheremotecontrolthatweneed,whichhasbroughtgreatimpactonourdailylife.Inordertomakemorepeopleunderstandtheremotecontrol,andtoupdatetheconceptofthetraditionalremotecontrolinpeople'smind,andletpeopleusetheremotecontrolmoreconvenient,Idecidedtodesignauniversalremotecontrolbasedonthemicrocontrollerwithlearningfunction.Thisproducthasdesignedthreemainfunctions,includinglearningfunction,decodingfunctionandremotecontrolfunction.Theremotecontrolpartcanbedividedintotwomodules,whicharetransmittingandreceiving.First,Iwillputthethreefunctionkeysandthematrixkeyboardbelowthecorrespondingcode,andthendisplaydifferentfunctionsandcorrespondinginfraredcodingafterinsertingthedisplayscreen.Whenweswitchtothelearningfunction,weneedtopressabuttonandlearnit,andthenthekeyintheremotecontrolisalignedwiththeproduct.Pressthebuttonthatislearningthespecificfunctionoftheremotecontrol.Thebuzzerwillhearasound,andthedisplaywilldisplaythecorrespondingredoutercodeandlearntocompleteit.Then,weswitchtotheremotecontrolfunction,pressthekeyoftheremotecontrolfunction,thebuzzerwillsound,andthenfindthatthedevicehascompletedtheoriginalremotecontrolofthecorrespondingfunction,thelearningandthelaunchingprocessends.Throughthedesignofthisproduct,Ihavedeepenedmyunderstandingofsingle-chiptechnology,changedmyunderstandingofinfraredtechnology,andrealizedthedesignofthefunctionsoftransmittingandreceiving,decodingandcoding,learningthroughcontinuousexperimentsandsummaries.Moreover,themonitorcandisplaydifferentfunctionsintuitively,whichisveryconvenient.Inaddition,therealizationoftheuniversalremotecontrolhasbroughtthegospeltomanyfamilies.Fromthenon,wecanuseonlyoneremotecontroltoreplacemanyhouseholdremotecontrolfunctionsandgreatlyimprovetheefficiencyofwork.Keywords:Singlechipmicrocomputer;rem...
