Optimization And Implementation Of Heterogeneous Item Coding Analysis Method Based On Internet Of Things

The Internet of Things technology has been widely used in human production and life.Coding,identification and analysis of heterogeneous items are the prerequisites for implementing the Internet of Things technology.Therefore,heterogeneous item coding and analysis technology is one of the core technologies in the field of Internet of Things,and it is also the basis for the wide application of Internet of Things technology in other fields.With the joint efforts of the International Organization for Standardization and other relevant organizations,the development of coding standards and parsing standards for the Internet of Things has been greatly promoted.However,there is currently no unified coding and parsing standard.The standards and information service interfaces used by the coding and parsing systems are incompatible with each other,making it difficult to implement a wide range of applications in the entire Internet of Things field.Therefore,in light of the actual needs in the field of Internet of Things,proper optimization of existing heterogeneous article coding standards and analysis methods is of great significance for the analysis and search of article coding under big data.Based on a detailed analysis of the existing mainstream standard system EPCglobal standard system,UID standard system,and CPC standard system based on coding standards and parsing methods,this paper proposes a heterogeneous system that supports multiple coding standards based on the DNS domain name resolution system.Item code analysis system.This system expands the DNS iterative analysis and uses NAPTR records to complete the conversion of the item code to the name of the object that meets the requirements of DNS analysis,thereby realizing the IoT heterogeneous item code analysis service.The system is designed based on the DNS iterative analysis process,which is divided into five layers: standard identification code analysis layer,item code analysis layer,item search addressing layer,item identification addressing layer,and item digital addressing layer.It also makes reasonable and effective use of OID data,completes the conversion of standard identification codes and item codes,and then completes heterogeneous item code parsing services.Finally,the system is developed on the Linux platform using C language,and the BIND DNS server is used to implement the DNS resolution process.The functional verification and test results of the system show that the system can meet the expected requirements in terms of encoding and parsing speed and accuracy,and can analyze EPC and Ucode encodings,verifying that the DNS domain name resolution system-based implementation of the IoT field supports multiple standards Feasibility of code parsing.At present,the coding and parsing system designed in this article is only the core functional part of the system.Based on this,in the future,it can be improved from the perspectives of access control capabilities and user authentication to make the system more complete.,Higher performance,better compatibility,stronger usability.
