Development Of Intelligent Gateway Of IOTs And Its Application

With the development of sensors,wireless communication,embedded system and other information development,it is a general trend to build Internet of Things in various fields.Internet of Things is being applied in all aspects of social life,such as intelligent logistics,intelligent transportation,smart home and so on,and all these applications are relying on all kinds of powerful IOTs gateways.According to different applications of IOTs,IOTs gateways vary widely.In this thesis under the agriculture environment,the original gateway is upgraded to intelligent gateway.This thesis reviews the research status of IOTs and intelligent gateways from home and abroad,designing an intelligent gateway with identification monitoring and remote collect,control system based on USB technology.First of all,USB interface is analyzed and then the basic hardware and software designs are given.Combined with the original gateway management function,a monitoring system based on RTMP media stream is developed,which forms an identification monitoring and remote collect,control intelligent gateway.In the overall the intelligent gateway consists of three main modules:perceived coordination processing,intelligent management and identification monitoring.Perceived coordination processing collects all kinds of sensor parameters.Intelligent management classifies reported parameters and interacts with the server.Identification monitoring provides a warning on all types of emergencies.Finally,this thesis use simulation system to test the intelligent gateway and to verify various functions.Test result shows that this design of intelligent gateway is feasible,which completed the goals of this thesis researched.At the end of this thesis,the thesis summarizes the done work and some future research directions are put forward for intelligent gateway,including charging time planning,remote automatic online update,application extension,and so on to reduce the daily maintenance costs.
