The Application Study Of Smart Home Based On ZigBee

With the comparison of the wired network and wireless network technology in the intelligent home, the comparison of several other wireless networking technology and ZigBee in this paper, the final conclution is ZigBee wireless communication network technology which is with low power, low rate, low cost, can meet the requirements of the smart home. So this paper uses ZigBee as wireless communication network technology of a smart home system.This paper uses the home as the research background to design the home's internal network and external network control system. ZigBee wireless communication within the network using wireless technology for home control. The internal network consists of the ZigBee protocol analysis, ZigBee wireless communication network device type, network structure and network topology structure. By analyzing of Home environment to determine the type of device and network topology of the entire system. External network uses SMS to remote control of domestic cats. The content of external network involves manipulation functions, including SMS cat, sending and receiving information. SMS uses AT commands to the sensor cat control.In the process of designing system, the home system has been studied in five aspects, including :1)deeply ZigBee study 2)the overall program design 3)system hardware design 4)system software design 5)system testing. Describe the overall design of the structure and composition of the system, network selection, sensor selection and design of the host computer. The hardware structure is about CC2430 hardware and hardware structure is about the cat messge. Software describes how to set up a new network, FFD process of joining the network, RFD join the network processes, systems, process alarm, network address allocation and routing analysis. System testing involves one or more network nodes results of the test and packet loss rate test.In this paper, VC + +6.0 is used to program serial port to implement the system data acquisition and processing functions.The results show that the wireless network technology of ZigBee can be successfully applied in smart home.
