Research And Application On Zigbee Technology In Smart Home Control System

Now as the information technology and network develop rapidly, everyone improves living requirements, and hopes to live in a more comfortable and convenient environment.The smart home control system and network become a popular topic at once .The development of broadband technology and wireless technology provides conditions for smart home system. Zigbee technology is a low rate wireless personal area network technology rising recently years, which is appropriate for a small scale and low-power consumption condition. Compared to broadband communication, it is more convenient with lower cost, and simpler than wireless technology.In this paper, Zigbee technology was used for the foundation of wireless sensor network. This paper designed a wireless sensor network system platform which was based on Zigbee technology. Related network communication protocols were developed , and solved problems as follows:(1)First, the paper described the architecture Zigbee protocol stack, the structure and function of each layer, related concepts on Zigbee technology application and development.Secondly, further research on topology of network was made in this paper. Besides, the equipment used in network and networking principle of each node were introduced in detail.(2)The paper described the method in detail to construct the hardware platform and software platform of lighting control system. S3C2440 was used as hardware development board, and choose CC2430 RF module as wireless module. Serial port was used to transplant Linux operating system to the embedded development board, setting up the embedded development platform. Then On the platform, family gateway and terminal nodes were developed .(3)At last , the paper tested a simulation through the smart home lighting system to analysis the function of Zigbee net control system and verify the net possess self-healing capability. Equipment was able to join in net dynamically . The system can satisfy the requirements of the function and performance of smart home control system.
