The Design Of Internet Of Things Smart Home System Based On Arm And Zigbee

With the rapid development of science and technology and the continuous improvement of living standards, people’s demand on the living environment tends to be higher and higher. Therefore smart home system that could be able to provide a safe, comfortable, convenient, fast, open, has already become a trend in the residential development of human society.In order to realize the remote management and wireless transmission function of the intelligent home system, this paper use the Samsung’s S3C2440chip and the related peripheral devices to form into home gateway control platform of the entire system, and home internal control network by using the ZigBee wireless network technology to realize in the design of the Internet of Things smart home system.In the paper, after analysis and research on the development status at home and abroad, as well as related technology of the Internet of Things smart home system that put forward the overall structure of the Internet of Things smart home system, namely the structure is mainly four parts composed of family gateway(master controller), terminal controlled equipment, family internal control network, external communication network. The terminal controlled equipment is mainly including control of family equipment, housing security system, residential management systems, home information management section.Within the family internal control network, using the Texas Instruments’s CC2530chip to achieve the functions of the coordinator node and the end node in the family internal control network, the home gateway(master controller), temperature sensor, relay is respectively connected with the CC2530radio frequency chip to design the household electrical appliances switch control module and temperature control module. Through the experiment test could verify the feasibility of system design.The design through a unified wireless protocol and the different control protocol to achieve the co-ordinate management of smart home system, reflects the humanity, intelligent, network features of the smart home system, providing a new solution to the smart home in the future.
