The Realization Of The Real-time State Diagram Of Iot Structure

In recent years,the technology of Internet,computers,wireless sensors,and communications are continuous developing and improving which have laid a good foundation for the development of the Internet of Things industry.Countries have taken it as a major strategy to preempt the commanding heights a new round of economic and technological development.Various Internet of Things products have entered thousands of households and become a necessary part of people's life which also makes the management of the Internet of things becomes an important issue for us.This paper focuses on the existing visualization software of the Internet of Things at domestic and overseas,and proposes a real-time display system based on Browser/Server three-tier architecture.By analyzing the existing IoT structure visualization system,it can be found that most of systems are developed using the client/server architecture.Systems based on this architecture are not only difficult to deploy but also need to develop different clients which also requires maintenance in the future,the workload is enormous.Therefore,it is necessary to develop a system based on B/S architecture,which consists of three parts: server,front page and database.Besides,it has realized the real-time drawing of the topography of the IoT,the query of the historical structure,the query of working status of each node,the detailed information statistics of each node,the real-time alarm and registration login.Currently,the browser has been embedded in a variety of operating systems,HTML5 and TWaver are used as the model of topological display.Once developed,it can be used on different systems.Developers only need to update the server side,greatly reducing the workload of developers and those people who need to maintenance this system.It also greatly increases the scope of deployment and usage.Adopt Node.js as the platform development server to realize WebSocket communication protocol for data transmission.Through our test,the system can accurately draw a topology map of the IoT structure and display the working status of each node.When a node failure is encountered,it can be promptly reported.Besides,this system has the compatibility with PC,mobile,Windows,mac OS,and Linux systems,which meet the design requirements.
