Design And Implementation Of WEB Real-time Publishing Scheme In IoT Monitoring System

With the continuous development Internet of Things(IoT)and its interrelate industries has become much more mature,and the consequent is the growing demand for real time for the users to monitor.How to allow users easy,flexible and effective access to IoT monitoring information become one of the key technologies used in practical IoT industrial need to be addressed.The Web as the most important Internet business is that people get the most important source of information.Its innate cross-platform characteristic makes access to information has become easy and convenient,and the new generation raised in HTML5 WebSocket technology to solve real-time interactive Web original problems,WEB technology combined with real-time monitoring of IoT has broad application prospects and important practical significance.Based on the above background,this thesis for IoT in the application of industrial combustion process,combines WebSocket technology and the Internet of things,then design and implementation of WEB real-time publishing scheme in IoT monitoring system.This thesis mainly includes the following aspects:Discussed commonly used AJAX long polling,iframe stream,Flash XMLSocket and several WEB publishing technologies,summed up its inferior.In-depth analysis of the HTML5 WebSocket protocol,including its essential part of a technical background,handshake,frame format,etc.for later combined WebSocket with IoT real-time monitoring technology to create the conditions.Contrapose IoT monitoring data for real-time publishing,designed to monitor the IoT real-time publishing scheme based on WebSocket.Build a suitable implementation of the B/S network architecture,and selected development environment and platform.Finally,achieved the WebSocket based IoT real-time publishing monitoring scheme,and write programs for the client and the server-side.Test results show that,aim at the WebSocket based IoT real-time monitoring system proposed in this paper,achieve access the client browser WEB interface in real-time publishing monitoring data from IoT,which achieve the system goal,meanwhile can be generalized to other IoT applications.
