Design And Implementation Of ZigBee Protocol Stack In Smart Home Internal Network Based On CC2530

China is in a rapid economic and technological development stage, people’sliving standards improved greatly, more and more people have increasingly demandon the comfort level of everyday life, and smart home came into being. Smart homesystem make the ordinary appliances interconnected through special techniquesforming an intelligent home network, it bring people novel experience and changes.This paper studies the current market needs, design a set of embeddedintelligent home systems, the external network connections using a variety of accesstechnologies, we use WiFi, GPRS and Internet make clients connected to homegateway, while within the family we innovatively use the ZigBee wireless sensornetwork communication protocol to achieve a home wireless networkinterconnection inside. Achieve remote control of smart home through handhelddevice wirelessly.This paper describes the development history and research status of smart home.Analysis the advantages and disadvantages of the smart home systems exist currently,put forward two improve plan on the external and internal network according tomarket demand.Then introduced the central controller and the control terminal, give out theoverview of the overall framework and key technologies were used, includingexternal network WiFi, GPRS, Internet and home internal network ZigBeecommunication protocol. Designed the hardware structure of central controller andcontrol terminal according to the demand, and described the functions and roles ofeach module in detail.Then introduced the build process of ZigBee protocol, the protocol stack aimsto CC2530RF chip produced by TI, and we uses lightweight system Contiki, wemake use of its event-driven mechanism to build physical layer and MAC layerservice program of ZigBee protocol stack, realizing reliable data transmission.Finally, the software design of smart home system central controller and thecontrol terminal, analysis the software implementation process simply. Describes thetemperature monitoring system and give out the overall structure of the work process,design PC control interface program, and its detailed function description.
