The Design And Implementation Of Smart Home System Based On Zigbee

In recent years,the concept of smart home has been well known in the c ountry,smart home technology has also been rapid development at home and a broad.Intelligent Home Furnishing can not only provide traditional living envir onment for people,but also the related technology and the Internet of things,s o that people can have network appliances,information appliances,intelligent s ecurity features such as full living environment.Today,more and more people yearn for intelligence,information and networking lifestyle,therefore,there will be more and more smart home market demand.Based on the analysis of the function and demand of intelligent home system,this paper designs a smart ho me system with perfect function,low cost,safety and stability.In this paper,Cortex-A9 is used as the core of the microprocessor,and the design and imple mentation of smart home wireless communication and environment monitoring,infrared learning and transmitting are realized.The overall design of the system is divided into three parts: the data acqu isition and control of the Zigbee terminal node,the program design of the mai n controller,and the design of the IP camera.In order to reduce the crosstalk of signals,this paper selects the Zigbee wireless communication protocol and s elects the latest CC2530 chip of TI company to solve the problem of signal cr osstalk.The main controller control coordinator through the serial port to realiz e node equipment management,including allowing access,does not allow acces s to restore factory settings.The sensing device node through the Zigbee netw ork data collected periodically transmitted to the main controller,the main cont roller not only can be updated in real time environmental information detected in the environment in the interface,but also through the control interface to co ntrol node.The main controller sends commands to notify the infrared transpon der learning infrared signal,and then stored in the main controller of the datab ase,for the use of infrared signal sent next time.Through the wireless networ k,the main controller can access the IP camera,the user can set the video qu ality of the IP camera,turn on the voice,turn off the voice and other monitor ing of the family situation.This paper designs an intelligent Home Furnishing system,a more compre hensive function of the test,through the IOTC protocol controller can successf ully access to the IP camera,the main controller can control the node by the Zigbee wireless communication protocol and can successfully receive feedback i nformation of nodes,the verification results show that the intelligent Home Fur nishing system designed in this paper meets the requirements.
