物联网:标志性特征与模型描述

Internet of Things:Differential Features and Descriptive Model

物联网的标志性特征支撑着物联网作为新事物的独立存在,物联网的模型描述则标志着对物联网的深入认知。语义分析表明:物联网之"物"特指"物的信息",物联网之"网"则是"互联网应用"。物联网是使全球共享物的信息的一种新型互联网应用。物联网的标志性特征有四:仅限于物的信息、UID/EPC编码、RFID电子标签存储、RFID读取器非接触式读取上载。物联网的图示模型揭示:实现物联网的专有工作是物的信息在上载互联网之前的预处理和RFID系统的建设。物联网的集合表示模型则突出了互联网应用的共同特征即"本质上都是一种信息集合",因而可借鉴和重用其它互联网应用的开发思路与技术措施。

The differential features can support Internet of Things existing as a new kind of development,and the theory model can indicate that Internet of Things has been understood deeply.A semantic analysis pointed out that the thing in word Internet of things indicates actually the thing＇s information,and the Internet is actually the Internet application.Internet of Things is a new type of Internet application which makes the thing＇s information be shared on a global scale.Internet of Things has four differential features：only for thing＇s information,coded by UID or EPC,stored in RFID electronic tag,uploaded by non-contact reading with RFID reader.The graphical model of Internet of Things shows that the main tasks of constructing Internet of Things are the preprocessing of thing＇s information before uploaded into Internet and the building of an RFID system.The set expression model of Internet of Things stresses the common character of Internet applications namely an Internet application is essentially a set of information,so the deve-lopment processes and the technical methods of other Internet applications can be referenced and reused.
