Design Of A Remote Control Smart Home System Based On ZigBee

With the progress of science and technology and the development of society,people's pursuit of the quality of life has also been improved.Home system is the highest frequency of the life of the scene.The quality of its design directly affects the quality of life.Providing a more intelligent security and comfortable home environment has becomes an urgent need of people.The traditional smart home system uses the way of wired wiring,the controller is realized by the family computer operation middleware,which need to use the computer for controlling the long time to maintain the running state and the mobile phone through the WiFi connection home router to find the local area network compute.Then realizing the short distance wireless control of home equipment through the computation machine running the middleware.Aiming at the shortage of the traditional smart home system,this thesis designs the smart home system based on the technology of ZigBee and remote server technology.Zig Bee wireless communication technology is used in the smart home gateway and each node,which changes the disadvantages of the traditional wired network method,the complexity of the system and the stability of the system.The controller is the home gateway which is used to control the home network interface.As the home gateway requires a long time to work for itself business,and the home gateway power consumption is low,so did not increase the household extra equipment and power consumption,achieving real energy saving.Through the remote server technology,the smart home system connects with the Internet,the users can monitor the home equipment at any time and anywhere,to truly achieve remote control.This thesis analyzes firstly technology research status and development trend of the domestic and international smart home and networking,and the ZigBee technology and Z-Stack protocol stack for a brief overview,and And then according to the problem of traditional smart home solutions,a new type of remote control smart home based on ZigBee technology is designed.Besides,it discussed in detail of the design of the home network and the remote server design in the new scheme.The home network design includes the construction of ZigBee network,the program design of different devices in ZigBee network,the framework and program design of the home gateway,the communication flow between the terminal equipment and the home gateway and the design of communication protocol.The remote server design includes the implementatio n of server load balancing,the choice of service model,the design of service program,and the design of data storage.Finally,the whole system is tested and verified,and the design scheme is summarized and prospected.
