【摘要】：随着信息技术的不断发展更新，嵌入式系统已经具备了十分完善的网络功能。同时，新兴的物联网由于打破了传统的互联网体系并实现了物物相连，因此得到了巨大的关注并取得了飞速的发展。将这几种技术结合起来必将是未来信息产业发展的趋势。其中，智能家居就是这几种技术完美结合的案例之一。本文针对普通居住环境，提出了一种基于嵌入式Linux系统的智能家居网关方案。通过结合嵌入式系统、Internet网络技术和ZigBee技术，实现了一个简单的智能家居系统，，并对智能家居网关的设计与实现进行了重点讨论。本文的研究主要集中在基于ARM处理器和Linux操作系统的智能家居网关软硬件的设计与实现。在智能家居网关上部署一个Web服务器，用户就可以在任何一台连网的PC上远程登陆并访问智能家居网关。用户登陆后可通过点击网页按钮向网关发送指令。同时，在网关上还设计了图形界面用来和本地用户实现交互，通过点击触摸屏上的按钮也可以向网关发送指令。网关收到用户指令后，再将指令转发给家庭ZigBee网络的协调器，最后由协调器将指令发送至终端节点，从而实现对终端节点所连接设备的控制。本文首先简要的概述了智能家居基本概念，并进一步阐述了智能家居国内外的发展现状和智能家居网关的发展趋势。然后确定了网关的总体设计方案及硬件设计方案。论文的重点是网关的软件设计，主要包括五方面的内容：(1)移植Linux操作系统到S5PV210处理器上，制作根文件系统，从而搭好嵌入式平台。(2)在嵌入式平台上编写应用程序实现网关的雏形。(3)在嵌入式平台上组建Web服务器从而提供HTTP服务，实现Internet访问。(4)在嵌入式平台上实现本地图形界面实现本地访问。(5)网关与ZigBee协调器的通信协议制定，实现嵌入式平台与ZigBee网络的通信。最终，测试证明本论文设计的基于嵌入式linux网关达到了预期设计目标。
[Abstract]:With the continuous development of information technology, embedded systems have been equipped with very perfect network functions. At the same time, the emerging Internet of things has broken the traditional Internet system and realized the material connection. Therefore, great attention has been paid and rapid development has been made. The combination of these technologies is bound to be the development trend of the information industry in the future. Among them, smart home is one of the cases of the perfect combination of these technologies. In this paper, a kind of intelligent home gateway scheme based on embedded Linux system is proposed for ordinary living environment. A simple intelligent home system is realized by combining embedded system with Internet network technology and ZigBee technology. The design and implementation of smart home gateway are discussed in detail. The research of this paper mainly focuses on the design and implementation of software and hardware of smart home gateway based on ARM processor and Linux operating system. A Web server, The user can log in remotely on any connected PC and access the smart home gateway. After landing, the user can send instructions to the gateway by clicking the web button. At the same time, A graphical interface is designed to interact with local users on the gateway. By clicking the button on the touch screen, the gateway can send instructions to the gateway. After receiving the instructions, the gateway will forward the instructions to the coordinator of the home ZigBee network. Finally, the command is sent to the terminal node by the coordinator to realize the control of the equipment connected by the terminal node. First of all, this paper briefly summarizes the basic concept of smart home, The development status of smart home at home and abroad and the development trend of smart home gateway are further expounded. Then, the overall design scheme and hardware design scheme of the gateway are determined. The emphasis of this paper is the software design of the gateway. Mainly including five aspects of content: 1) transplanting the Linux operating system to the S5PV210 processor and making the root file system. Thus build the embedded platform. 2) write the application program to realize the prototype of gateway on the embedded platform. Build the Web server on the embedded platform to provide the HTTP service. Implement Internet access. 4) implement the local graphical interface on the embedded platform to realize the communication protocol between the gateway and the ZigBee coordinator, and realize the communication between the embedded platform and the ZigBee network. The test results show that the embedded linux gateway has achieved the desired design goal.
