[Abstract]:The smart home is the application and extension of the Internet of things in the home. It is the main development direction of the future home life. It is also one of the hotspots in the research of the application of the Internet of things. The smart home gateway plays an extremely important role in the smart home system. Its main function is to complete the formation of the internal network of the home court and to be between the external network and the external network. The smart home gateway can realize intelligent home equipment, control and manage the network. It is the core component of the intelligent home system. This paper makes a detailed analysis and introduction to the development and development trend of the smart home gateway. Some shortcomings in the cost and other aspects, combined with embedded, Internet, WIFI, Zig Bee, sensor and other technologies, proposed an intelligent home gateway solution based on the Internet of things architecture. The main contents of this paper are as follows: (1) based on the architecture of the Internet of things, the research and design of the awareness control layer, network communication layer and should be designed. The intelligent home system of three layer architecture composed of service layer is used to analyze the function and function of the smart home gateway in the intelligent home system. Based on the embedded processor module, the Ethernet interface module, the Wi Fi communication module, the Zig Bee communication module and so on, the hardware system of the intelligent home gateway is designed. (2) OpenWrt On the basis of operating system, the software system of smart home gateway is designed. Local server and remote communication interface are designed by modular method. The remote or close range control and management of home equipment through client device, and the perception and collection of home environment information data are realized. The authentication protocol between the client of the NTRU algorithm and the smart home gateway enhances the security of the system. (3) the composition and characteristics of the intelligent home network are studied and analyzed. The intelligent home network of star structure is designed on the basis of ZigBee. On the basis of Z-Stack 2007, a program of Zig Bee network management and equipment information acquisition is set up. In this paper, the management, control and information collection of Zig Bee terminal devices are presented. Through the combination of Zig Bee network and Wi Fi network, the advantages of Zig Bee communication in networking and power consumption as well as the advantages of Wi Fi communication in stability and transmission rate are fully utilized. The intelligent home network system is formed. (4) research and design the intelligence of intelligent home network. Home gateway personalized setup scheme, using "role mechanism", divides users into 3 levels of parents, children and visitor levels. By identifying user identity information, intelligent home gateway provides different functional services for different users. Finally, the design of intelligent home system verification platform, server and mobile client, to the system The test results show that the smart home gateway scheme can be used in most home environment, can realize the perception of home environment, collection and control of home equipment, realize the home intelligence and convenience of life. The scheme has the advantages of low power consumption, good stability, low cost, small volume, and perfect function.
