Research And Implementation On Identifier Resolution System Based On Internet Of Things

With the development of technology, the interaction of information has becomemore and more frequent. As an emerging industry, internet of things has receivedwidespread attention. Perfect identifier resolution system is the basis of thedevelopment of internet of things. The purpose of identifier is to transform codedobject information to carrier portable information. The process of identifier resolutionis analyzing identifier, finding out the objective information. There are many codingstandards, each of which has different parsing mechanism. It is very adverse to thedevelopment of internet of things that one standard can’t connect to another and it isalso unrealistic to develop a unified object coding standard, so it is very necessary toresearch and design a parsing mechanism which can be compatible to various kindsof mainstream coding methods.Due to the backgrounds and problems in the foregoing paragraph, I design apubic identifier resolution system which is compatible to various kinds of codingstandards. The system can realize the united register and management and also parsevarious kinds of coding identifier. In the paper, I firstly analyze various kinds ofcoding standards and then come out the conclusion that nowadays mainstream EPCand ucode coding both use the DNS parsing mechanism of Internet. Throughcontrasting to DNS iteration parsing model, I demonstrate that the formal descriptionof parsing model for internet of things is conformed to that of the Internet and itindicates that DNS resolution mechanism can be extended to resolve compatibility forvariety of coding schemes. Because object coding of internet of things has dispersedand unknown characters, whereas the DNS can only parse the resource names withunity and comprehensibility such as domain name. So analytic system designed inthis paper during the coding analysis, we must first obtain the corresponding standardidentification code, get articles coded information in accordance with the standardclassification identification code, and then obtain expressions describe NAPTRresource records based on the positive encoding preset conversion rules for goodsencoding presets conversion, coding items to meet the full item information domainname format conversion, and then use DNS resolution mechanism to complete the article to get more information. This article also designs the communication interfaceof middleware and the coding register management module which makes the systemable to achieve a unified registration EAN management. In this paper, EPC encoding,ucode coding and CPC coding analytical validation proves the system can achieve avariety of coding resolution. Finally, this system is applied to the areas of the smarthome and makes it possible to unified registration and resolution. It resolves theidentifier positioning and interconnection of smart home.
