物联网的关键技术摘要物联网是一个基于互联网、传统电信网等信息承载体，让所有能够被独立寻址的普通物理对象实现互联互通的网络，是新一代信息技术的重要组成部分，近年来发展迅速，具有广阔的应用前景［1］。作为动态的全球网络基础设施，它的根本是物与物、人与物之间的信息传递与控制。物联网技术是一项综合性的技术,涵盖了从信息获取、传输、存储、处理直至应用的全过程，其关键在于传感器和传感网络技术的发展和提升，根据侧重点不同物联网技术的划分标准也不同，国际电信联盟的报告分为四大关键性技术：标签物品的 RFID、感知事物的传感网络技术、思考事物的智能技术、微缩事物的纳米技术［2］。本文首先介绍这些技术的基本原理和发展，并就其中的几个核心技术进行详细的认识和探究,同时分析技术应用背后面临的问题和挑战，为物联网的发展提出更具前瞻性的建议。关键词：物联网关键技术 RFIDAbstractTheInternetofthingsisabasedontheinformationsuchastheInternet,thetraditionaltelecommunicationnetworkbearer,sothatallcanbeindependentlyaddressableordinaryphysicalobjectstoachieveinteroperabilityofnetworksisanimportantpartofthenewgenerationofinformationtechnology,therapiddevelopmentinrecentyears,withabroadProspects.Asadynamicglobalnetworkinfrastructure,itissimplythetransmissionofinformationandcontrolthingsandthings,betweenpersonsandthings.Thingstechnologyisanintegratedtechnology,coveringtheinformationobtainedfromthetransmission,storage,processinguntilthewholeprocessoftheapplication,thekeyliesinthesensorandsensornetworktechnologydevelopmentandpromotion,accordingtothedifferentfocusofnetworkingtechnologydifferentcriteriafortheclassification,theInternationalTelecommunicationUnionreportisdividedintofourkeytechnologies:labelitemsRFID,sensornetworktechnologyperceivethings,thinkaboutthingssmarttechnology,miniaturethingsnanotechnology.Thispaperdescribesthebasicprinciplesanddevelopmentofthesetechnologiesandadetailedunderstandingandexploringonafewofthecoretechnology,andanalyzestheproblemsandchallengesfacingthetechnologybehindtheapplication,putforwardmoreproactiveproposalsforthedevelopmentofthings.Keywords：WebofThings，keytechnology，RFID...
