[Abstract]:With the development of science and technology and the improvement of living standards, people began to pursue a more comfortable and safe living environment at home. Home intellectualization has become a trend. Smart home system forms a smart home living environment by connecting various independent electrical devices within the home. Greatly improve the comfort and convenience of people's daily life. Based on the domestic and foreign research status of smart home system, this paper designs and implements a kind of intelligent home lower computer system based on embedded technology. The system is composed of home gateway, intelligent control terminal, supports a variety of communication modes, can control a variety of home devices, among which, the function of home gateway is: through Ethernet. GPRS or WIFI is connected to the external network to manage the system. The control terminal is mainly used for local control and real-time display, with monitoring of environmental information, control lights and switches. Air conditioning and other electrical equipment functions. Both have the ability of fault alarm and automatic repair. Wireless communication technology eliminates the cumbersome wiring procedures of home equipment. It is widely used in intelligent furniture system. Several wireless communication technologies are commonly used: Bluetooth WiFi. GPRS and ZigBee. among them, ZigBee wireless communication technology has the characteristics of flexible networking and low power consumption. It is the key technology of this design, based on ZigBee wireless communication technology. In this paper, we put forward the inner networking scheme of smart home system and design the heterogeneous network communication protocol. This paper focuses on the design of home gateway and intelligent control terminal. Firstly, the functional requirements of home gateway and intelligent terminal are analyzed. Following the concept of low-power design, the hardware architecture of home gateway and control terminal is designed. At the same time, the circuit design of each functional module and the main parameters of the module are explained. In order to realize the function of the system, the hardware design is completed. The software design of the home gateway and the control terminal is carried out. Similar to the hardware design, the software architecture of the home gateway and the control terminal is designed according to the specific requirements, and the software workflow of each part is given. In addition, the design node is used to verify the correctness and validity of the dynamic topology optimization algorithm of ZigBee wireless sensor network. The topology changes when the power is exhausted off the line. The proposed dynamic topology optimization algorithm can improve the connection rate of the network on the one hand and balance the load of the routing node and terminal equipment on the other. The simulation results show that the proposed dynamic topology optimization algorithm can improve the network connection rate and balance the load of the routing node and terminal equipment. The improved algorithm improves the network connectivity, prolongs the network life, and optimizes the power consumption from the whole system level. After the system design is completed, the mobile phone is adopted. The control function of the system is tested by the upper computer and the intelligent remote control terminal. The results show that the user can realize the basic control of the smart home system through different clients, and the system operation is complete. Achieve the desired effect.
