Design And Implementation Of Smart Home System Based On Wireless Network

The nineteen major reports of the party have pointed out that the main contradictions in our society have been transformed into the contradiction between the growing demands for the people’s better life and the imbalance of development and the inadequate development,which shows that the people’s demands for the quality of life are constantly improving.The smart home industry,which is closely related to people’s quality of life,has become a hot spot.Domestic solutions for smart home already exist,but most of them are one-sided.There is no systematic solution,and the existing schemes remain at the stage of separating the gateway from the nodes and separating the hardware from the software system.In addition,there are obvious differences in the mode of communication between the existing smart home devices,and solutions are proposed,but most of them are only considered in a very small space and can not be integrated into a large network.For example,we have infrared appliances in every room,and there is no plan to solve this problem.Moreover,the way of wired communication has brought great trouble to the installation and free expansion of smart home system.In view of the above problems,based on the systematic research and analysis of the current sit uation of smart home,this paper consults a large number of documents and materials.By studying and studying embedded development and network application technology,a set of low cost intelligent home system based on wireless networking is designed,which realizes the integration of the router and the smart home gateway.The whole smart home system solves the inconvenience of installation inconvenience caused by wired communication by establishing a wireless network.Considering the low cost and rate transmission demand,the routing gateway of smart home system has established two wireless networks: ZigBee network and Wi-Fi network.The ZigBee network is used to transmit data with lower speed requirements,such as environmental parameter data,control device data,etc.The Wi-Fi network is used to transmit high speed data,such as video data.The infrared learning module is added to the ZigBee routing node to establish the connection with the infrared equipment,which makes the infrared communication equipment join the smart home wireless network.Routing gateway builds Wi-Fi network by transplant OpenWrt routing system,and connects LAN to WAN to realize routing function.The web server Uhttpd is embedded on the software system platform of the routing gateway,and the LuCI framework is used to develop the Web control interface of the smart home system to control the function of the home equipment through the web interface.By designing a humanized WEB interface with a room as a unit,it is convenient for the user to manage and control home equipment,and to meet the needs of the user to expand the routing nodes of the room.By installing msmtp and mutt software on the system platform,we use script files to complete the e-mail reminder function.The mobile phone client is written in JAVA language,which enables users to use mobile phones to control household devices and to view room information.By applying dynamic domain name,the dynamic domain name service and port mapping are configured on the system platfo rm of the routing gateway to realize remote control.
