Component Design And Implementation Of Trend Control System Based On IoT

Nowadays,the number and variety of sensors accessed in the trend system of the Internet of Things are becoming more and more diversified.The traditional situation-based display control system can neither meet the demand of users to intuitively and quickly conduct multi-dimensional and comprehensive observation and control of the target,Different sensor combinations in the scene for easy expansion and modification.Based on the above background,this paper presents a scheme of using GIS technology to organize and sort out the multi-sensor information and make use of the organizational structure of the component technology to realize the physical presence of the Internet of Things.The aim is to make up for the situation of the traditional situation system in the comprehensive,visual effect,maintainability,Scalability deficiencies.The IoT trend display control system adopts Spring MVC framework to build websites,uses MVVM architecture to build page structure,uses React,cloud GIS API,HTML5 Canvas,HTML5 local storage,AJAX and other technologies to realize data visualization,access webpack automatic construction tools for performance optimization.According to the function division,the control system is divided into two modules:data visualization and GIS map access.The GIS map access module is the basic module of the system,and the data visualization module is the core module of the system.At the same time,because the data type has two kinds of original data detected by the device and analysis data after the data processing platform,the data visualization module will be divided into a device-oriented device display control module and a target-oriented target fusion display control module Two parts.From the component point of view,the situation control system through the top-down way to achieve the overall component.The system first divided into navigation bar,sidebar,GIS map shows the three major components,and then according to the specific responsible for the different functions,one by one under the various components of the sub-components.This article describes in detail the implementation of each component and principle,gives a concrete and reliable composition of the Internet of Things trend control program.Finally,after a detailed performance test,this paper visualizes the performance improvement brought by webpack automatic build tools to the system,and confirms the feasibility and superiority of introducing web front-end build process.
