Research And Design Of Home Controller System Based On Fusion Technology Of ZigBee And WiFi

Smart home system has gradually become the hot spot area which focused the people’s attention and research interests in recent years.Smart home industry is occupying the Iot industry market.As the core of smart home system,smart home controller is mainly responsible for the entire system network construction and maintenance,data transmission and processing and human-computer interaction.Based on the study and analysis of the current development status on the field,and aimed at the lack of uniform standard and poor compatibility of intelligent home controller,a smart home controller is developed,which is a fusion of ZigBee and WiFi network technology and versatility.First of all,this paper analyzed ZigBee,WiFi and Embedded technology,and proposed system scheme architecture on the basis of the principle of design.Furthermore,this paper introduced and explained the hardware design of smart home controller in detail,and built embedded processor i.MX287 minimal system,and designed the terminal node and its peripheral functional circuit principle.Fourthly,the embedded system is built.This paper focuses on the embedded controller Ethernet,ZigBee,WiFi,serial application and a terminal node function modules and functional analysis software,and uses Qt to complete system interface to finish this design.Finally,the controller network function and the whole machine monitoring function is tested and analyzed.The experimental results show that,the smart home controller could well complete the interaction between ZigBee and WiFi and network data technology.This research can meet the design principle and realize the collection of intelligent home environment and the remote control of household equipment.It has the advantages of strong compatibility and convenient expansion,which is conducive to the popularization and development of smart home control system.
