【摘要】：隨著信息技術的不斷發(fā)展更新，嵌入式系統(tǒng)已經(jīng)具備了十分完善的網(wǎng)絡功能。同時，新興的物聯(lián)網(wǎng)由于打破了傳統(tǒng)的互聯(lián)網(wǎng)體系并實現(xiàn)了物物相連，因此得到了巨大的關注并取得了飛速的發(fā)展。將這幾種技術結合起來必將是未來信息產(chǎn)業(yè)發(fā)展的趨勢。其中，智能家居就是這幾種技術完美結合的案例之一。 本文針對普通居住環(huán)境，提出了一種基于嵌入式Linux系統(tǒng)的智能家居網(wǎng)關方案。通過結合嵌入式系統(tǒng)、Internet網(wǎng)絡技術和ZigBee技術，實現(xiàn)了一個簡單的智能家居系統(tǒng)，，并對智能家居網(wǎng)關的設計與實現(xiàn)進行了重點討論。本文的研究主要集中在基于ARM處理器和Linux操作系統(tǒng)的智能家居網(wǎng)關軟硬件的設計與實現(xiàn)。在智能家居網(wǎng)關上部署一個Web服務器，用戶就可以在任何一臺連網(wǎng)的PC上遠程登陸并訪問智能家居網(wǎng)關。用戶登陸后可通過點擊網(wǎng)頁按鈕向網(wǎng)關發(fā)送指令。同時，在網(wǎng)關上還設計了圖形界面用來和本地用戶實現(xiàn)交互，通過點擊觸摸屏上的按鈕也可以向網(wǎng)關發(fā)送指令。網(wǎng)關收到用戶指令后，再將指令轉發(fā)給家庭ZigBee網(wǎng)絡的協(xié)調器，最后由協(xié)調器將指令發(fā)送至終端節(jié)點，從而實現(xiàn)對終端節(jié)點所連接設備的控制。 本文首先簡要的概述了智能家居基本概念，并進一步闡述了智能家居國內外的發(fā)展現(xiàn)狀和智能家居網(wǎng)關的發(fā)展趨勢。然后確定了網(wǎng)關的總體設計方案及硬件設計方案。論文的重點是網(wǎng)關的軟件設計，主要包括五方面的內容：(1)移植Linux操作系統(tǒng)到S5PV210處理器上，制作根文件系統(tǒng)，從而搭好嵌入式平臺。(2)在嵌入式平臺上編寫應用程序實現(xiàn)網(wǎng)關的雛形。(3)在嵌入式平臺上組建Web服務器從而提供HTTP服務，實現(xiàn)Internet訪問。(4)在嵌入式平臺上實現(xiàn)本地圖形界面實現(xiàn)本地訪問。(5)網(wǎng)關與ZigBee協(xié)調器的通信協(xié)議制定，實現(xiàn)嵌入式平臺與ZigBee網(wǎng)絡的通信。最終，測試證明本論文設計的基于嵌入式linux網(wǎng)關達到了預期設計目標。
[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.
