Design And Realization Of Intelligent Home System Based On Zigbee And ARM

At present,China's smart home industry is developing gradually,but there are some problems in the realization of technology:(1)home system network is mostly wired connection,installation cumbersome,function upgrades and equipment maintenance more difficult;(2)the server has large power consumption and complex equipment;(3)although there are a small number of household products to achieve wireless control,but the function of a single location,the lack of control of household equipment multifunction.In this paper,ZigBee wireless technology is used to design the internal network communication mechanism of the home,and the terminal nodes are connected to the indoor equipment,and the use of embedded technology to ARM as the center to establish a home gateway platform,external access to the Internet via Ethernet,internal access ZigBee wireless network through the serial port.Through the mobile phone and other mobile terminal for a variety of home appliances for free control,to achieve the remote monitoring of home appliances.After testing the home system,the system can accurately monitor the indoor temperature and humidity changes,light intensity and indoor activities,and the gateway server can interact with the home network and the terminal device.At the same time,the terminal equipment information can be transmitted to the browser through the server to the user,and can freely control the operation of the home equipment through the web interface,thus realizing the purpose of remote monitoring of home appliances.This topic uses the ZigBee technology to set up the internal wireless network.The network structure of the star topology of the coordinator and terminal node is chosen to avoid the complicated and complicated wired connection,conducive to equipment installation and maintenance.Terminal node and equipment execution module are used in the home system terminal,which is convenient for the expansion and removal of the function of the home system.The use of embedded technology to streamline the ARM9 processor as the core of the family gateway server.According to the system requirements to add and delete related functional devices,reducing the server power consumption.By adding Ethernet interface and based on the TCP/IP protocol,the mobile client can access the home devices freely.
