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 RFID II Abstract The Internet of things is a based on the information such as the Internet, the traditional telecommunication network bearer, so that all can be independently addressable ordinary physical objects to achieve interoperability of networks is an important part of the new generation of information technology, the rapid development in recent years, with a broad Prospects. As a dynamic global network infrastructure, it is simply the transmission of information and control things and things, between persons and things. Things technology is an integrated technology, covering the information obtained from the transmission, storage, processing until the whole process of the application, the key lies in the sensor and sensor network technology development and promotion, according to the different focus of networking technology different criteria for the classification, the International Telecommunication Union report is divided into four key technologies: label items RFID, sensor network technology perceive things, think about things smart technology, miniature things nanotechn...
