For Software-defined Smart IoT Gateways Research And Design

With the advent of the 5G era and the rapid development of smart terminals,5G has provided strong technical support to promote the innovation of the Internet of Things.The formulation of 5G standards meets the Internet of Things' needs for network speed,bandwidth,and security.Under the vision of the Internet of Everything and the high penetration rate of Io T applications,a large amount of Io T smart terminal data will be generated anytime and anywhere,and the Io T gateway data will be diversified,quantified and complicated.This also brings the problem of how to achieve data management agility,efficiency,and lack of stability for the data management of the Io T gateway.The traditional Io T gateway has a single function mode,tedious networking operations,and insufficient specialization of scenario modes.It has been unable to meet users' needs for product interaction,user self-control,and "fool operation".First of all,this article aims at the increasingly complex,diversified and high-incremental Io T perception layer data,which brings pressure on data management and insufficient performance in data processing.This paper proposes a data management model for Io T gateways based on transaction-driven processes.Agility,efficiency and stability of data processing.Secondly,it addresses the issues of software-defined Io T gateway functions,data frame protocol format,and configuration of the perception layer mode,as well as unified management of terminal equipment,multi-protocol integration,and provision of data to cloud servers.This paper designs a set of software-oriented intelligent Io T gateway architectures.The architecture is divided into perception layer,information storage layer,network layer,data analysis and processing layer,and instruction set layer.Enhance the rapid integration of gateways with scenarios and requirements,and implement software-defined gateway functions.Finally,in view of the heterogeneity of Io T gateway functions,this article implements a software-defined intelligent Io T gateway software and hardware platform.The Io T gateway provides a set of general-purpose instruction set scheduling interfaces to the upper layer to meet the user flexibility.Define the requirements of the gateway,realize the heterogeneity of the gateway functions,and the pluggable hardware modules.This paper designs and implements a software-defined intelligent Internet of Things gateway,integrated instruction set design related technologies,software-defined related theoretical technologies,transaction-driven related methods,multi-protocol heterogeneous fusion related technologies,information storage related technologies,and the use of the Internet of Things Gateway-related technologies enable flexible software definition of Io T gateway functions.The gateway designed in this article has been put into practical application.Dozens of sets have been installed in the school's logistics intelligent industry exhibition halls,laboratories,hotels,Internet cafes and other places.It has been running stably for more than a year and has been well received by users.At present,the intelligent Io T gateway It has signed a strategic partnership with Zhuji Power Supply Bureau.This intelligent Io T gateway has practical application value.
