Design Of Intelligent Household Based On Internet Of Things

With the popularity of global information technology,mobile Internet era arrives.Traditional household life style is gradually beginning to date,at the same time,people have a higher pursuit for more comfort and safety household life.This paper is mainly the design of the household automation system based on Internet of Things.Through the concept connection of Internet of things technology with intelligent household system,the paper builds an intelligent household system which can use different ways to control terminal controller.Through a combination of ARM technology and network technology zigbee,either external or local area network can be used to control the Household appliances.This paper has the following work content:First of all,the design scheme is made according to the demand of the exploitation of intelligent household technology.And on the basis,the author builds a hardware platform of this system with ARM9.Then the features of the linux operating system are analyzed in detail,introducing the build process of the development environment of embedded linux.At a result,the development platform of household automation system is built.Then,the paper introduces the key techniques used in the system.Firstly,the characteristics of zigbee network are analyzed,and according to the Zigbee network prosperities,we build the Zigbee network based on Z-Stack protocol stack.Besides,the paper completes the design of software of system coordinator and the terminal node.Then,the principle of CGI technology is analyzed profoundly,and the role of CGI interactive program in B/S architecture system and program the CGI interactive is also analyzed.At last,the paper elaborates the process how to build QT embedded development environment,and on the basis the design of system local visual control interface is achieved.The third is about the implementation of the functional modules of the household automation system.In the part,we focus on the principles and design methods of LED mixed brightness,color temperature adjustment,hazardous gas detection,infrared repeater module,security prevention monitoring and home automine module.The household automation systems designed in the paper can achieve the control of household appliances and monitoring of family environment and by the use a variety of control terminals.The test of the system in the last part of the paper verifies that the final results of this paper can meet the anticipative aim.
