The Design Of Intelligent Housing System Based On Wifi And Zigbee

In China,as the popular of 3G mobile system and commercialization of 4G mobile system have set off the wave of mobile internet,more and more people are interested in smart home system now.This thesis gives a system solution of smart home system based on Zigbee and WiFi technology with advantages of low cost,high reliability,good extendable,easy centralization and complete IP transmission.Smart home gateway,smart home terminal and management software based on Zigbee and TCP/IP protocols are three main parts of this smart home system.Smart home gateway selects ARM Cortex-M3 and CC2530 MCU to set up the Zigbee network,analyzes and processes the network data,then transmits data by Zigbee and WiFi network.Smart home terminal gather and process sensors’ data according to gateway’s transmit commands,return feedback data to complete control function.Management Software implete centralized management for cross platforms and OTA upgrade based on TCP/IP protocol and IPMI SOL specification.In this thesis,system design solution of Smart home system has been confirmed first,then detailed circuit of smart home gateway and terminals are designed,software coding and system commissioning is carried out on hardware platform,finally the smart home system is set up based on four classic applications.According to the test results,this system has been certified stable,convenient,innovative and practical.
