Design of Smart Home System Based on Zigbee

Abstract

Constructing efficient, convenient and cozy home environment has become the current hot spot by using Zigbee wireless communication technology. This paper simply introduces ZigBee technology including the architecture and network topology of Zigbee2007/Pro protocol stack firstly, and then proposes a design plan of a remote supervisory control system based on Zigbee2007/Pro protocol stack for smart home applications and shows the hardware and software design of the system. This system uses ZigBee Wireless Technology to build home internal network, and connect a variety of sensors and home appliance controller to Zigbee network node. Various signals collected by a few end-nodes may be delivered by this system to the main control module, which will analyze and process them. Then the main control module transfers this information to internet or cellphone through the Ethernet and GSM/GPRS network to remotely and locally monitor and control family inner environment and household appliances. Furthermore, the working condition of the system can be traced into the SD card.
