题目：浅谈MC34018数字音频在楼宇门控对讲系统的应用英文题目：TheapplicationofMC34018digitalaudiointhebuildingdoorcontrolintercomsystem摘要随着物联网信息时代的普及和广泛的应用，智能化系统也被普遍运用，顺着时代飞速发展，楼宇呼叫对讲系统已经在人们的生活中普及，不管是办公商用，还是小区住户自用，人们的安全意识越来越高，人身安全以及财产安全的需求也随之急迫。然而，楼宇对讲机很好的为人们的人身财产安全提供了保障，楼宇对讲在当今时代越用越多，在未来的市场，楼宇对讲是非常有潜力的，互联网越来越发达，随着云技术的应用，楼宇对讲系统也开始迈入了“云端”的技术范畴，但是不少住宅、楼盘还是采用比较安全可靠以及稳定的模拟以及数字对讲，对讲则直接采用音频模拟信号，很容易产生吵杂的杂音，以及不稳定的音频，这些都是多数系统的问题。把半双工语音芯片MC34018应用到现有的楼宇对讲系统设计中，MC34018能够很好的解决回声、杂音、对讲时的声音小、音频信号不够稳定等问题本文首先从目前主流的楼宇对讲系统的进行介绍，然后对半双工语音芯片MC34018应用在楼宇进行分析，并找出缺陷与优势。关键词：二总线制；MC34018；楼宇门控AbstractWiththepopularizationandwideapplicationoftheInternetofThingsinformationage,intelligentsystemshavealsobeenwidelyused.Followingtherapiddevelopmentofthetimes,buildingcallintercomsystemshavebecomepopularinpeople'slives,whethertheyareofficecommercialsorresidentialresidents,andpeopleWithincreasingawarenessofsafety,theneedforpersonalsafetyandpropertysecurityisalsourgent.However,buildingwalkie-talkiesprovidegoodprotectionforpeople’spersonalandpropertysafety.Buildingintercomsarebeingusedmoreandmoreinthemodernera.Inthefuturemarket,buildingintercomisverypromising,andtheInternetisbecomingmoreandmoredeveloped.Theapplicationofcloudtechnology,buildingintercomsystemalsobegantoenterthe"cloud"technology,butmanyresidential,realestateormoresafeandreliableandstableanaloganddigitalintercom,intercomisdirectlyusingaudioanalogsignals,Itiseasytoproducenoisynoise,aswellasunstableaudio,thesearetheproblemsofmostsystems.Byapplyingthehalf-duplexvoicechipMC34018totheexistingbuildingintercomsystemdesign,theMC34018canwellsolvetheproblemsofecho,noise,smallvoiceduringintercom,andunstableaudiosignal.Thisarticlefirstintroducesthecurrentmainstreambuildingintercomsystem,thenanalyzestheapplicationofthehalf-duplexvoicechipMC34018inbuildings,andfindsdefectsandadvantages.Keywords:Twobussystem；MC34018；Buildinggatecontrol目录独创声明.....................................................................................................I摘要...........................................................................................................IIAbstract引言............................................................................................................11.内容概述.................................................................................................21.1设计特点.........................................................................................22.MC34018参数介绍................................................................................22.1衰减器..............................................................................................22.2MC34018在门控对讲的应用.........................................................33数字音频对讲系统的组成.....................................................................33.1数字音频对讲在楼宇门控对讲应用..............................................44.施工布线...................
