The Design And Realization Of Wireless Smart Home System Based On ZigBee

With the development of modern science and the raising of people's living standard, residents put forward the higher demand on the house' function and quality.Smart home are popular because of their safety, comfort, expedite information and perfect service. In consequence, they are likely to stand for the trend of modern housing. So it's very important to study and develop intelligence products which can meet the request of people.The research of smart home of low power consumption, low cost, easy group network, is a multi-disciplinary to cross subjects for research which are relevant to automation, computer, communication, etc. It is now widely recognized that standards such as Bluetooth and WLAN are not suited for low power applications, which is due to these standards' high node costs as well as complex and high power RF-ICs and protocols. ZigBee is a new global standard for wireless connectivity, having wide foreground of products within home control, building automation and industrial control and monitoring.In this thesis, a standard ZigBee network platform is constructed using PIC18LF4620 MCU and RF transceiver CC2420. Interfacing with the Stack for the ZigBee Protocol,some ZigBee network function are demonstrated such as forming a network,joining a network,end device binding etc. On the basis of this platform, we introduce a wireless smart home system based on ZigBee technology. The system's main function include remote control,automatic safety alarming,Man-Machine Interface etc. The function of remote control is design on the PSTN. At last we test the whole system's functions.The results of experiment show that the smart home system as this paper introduced has strong functions and low price, short development period, convenient maintenance and higher application value.
