【摘要】：科學(xué)技術(shù)的進(jìn)步提升了社會(huì)的普通大眾對(duì)家庭生活的需求,如何提供更加簡(jiǎn)潔、更加方便的生活一直困擾著許多IT供應(yīng)商。伴隨著嵌入式技術(shù)以及現(xiàn)代信息技術(shù)的飛速發(fā)展,家庭智能化、便捷化的愿望也就變得不再那么遙不可及。我們可以把家庭生活中的每一個(gè)智能電器當(dāng)成一個(gè)網(wǎng)絡(luò)節(jié)點(diǎn),對(duì)每個(gè)節(jié)點(diǎn)進(jìn)行組網(wǎng)從而形成家庭網(wǎng)絡(luò),并且使得家庭網(wǎng)絡(luò)與Internet相連接。這樣,我們可以發(fā)送命令,通過Internet傳輸信息到家庭內(nèi)網(wǎng),從而實(shí)現(xiàn)對(duì)家用電器的控制。而在內(nèi)部網(wǎng)絡(luò)和外部網(wǎng)絡(luò)之間起到信息交互作用的,便是本論文所要設(shè)計(jì)的嵌入式智能家庭網(wǎng)關(guān)。智能家庭網(wǎng)關(guān)是家庭內(nèi)網(wǎng)和Internet的橋梁,在智能家庭中起到的是信息的轉(zhuǎn)換作用。它既是信息的發(fā)送者也是信息的接受者。 在本論文中所設(shè)計(jì)出的嵌入式智能家庭網(wǎng)關(guān)具有功耗小,體積小,易放置和移動(dòng),穩(wěn)定性強(qiáng)等優(yōu)點(diǎn)。本文的研究?jī)?nèi)容主要如下： 1.對(duì)國(guó)內(nèi)外的嵌入式智能家庭網(wǎng)關(guān)做了一個(gè)簡(jiǎn)單的比較和分析,總結(jié)出現(xiàn)在國(guó)內(nèi)外現(xiàn)有的家庭網(wǎng)關(guān)的優(yōu)劣性。國(guó)外的所設(shè)計(jì)的家庭網(wǎng)關(guān)標(biāo)準(zhǔn)、協(xié)議、看法與國(guó)內(nèi)的有差別,國(guó)內(nèi)現(xiàn)有的家庭網(wǎng)關(guān)功耗大、體積大,不能滿足人們的家庭生活需求,同時(shí)強(qiáng)調(diào)了為了滿足人們對(duì)家庭生活的需求,表明設(shè)計(jì)一種更加方便快捷的智能家庭網(wǎng)關(guān)的迫切。 2.對(duì)整個(gè)系統(tǒng)的設(shè)計(jì)采用了一種自頂向下的設(shè)計(jì)模式。首先對(duì)即將要設(shè)計(jì)的家庭網(wǎng)關(guān)做整體的功能性分析,然后對(duì)各個(gè)功能模塊進(jìn)行拆卸分析和設(shè)計(jì),這是一種現(xiàn)在普遍使用的嵌入式系統(tǒng)設(shè)計(jì)模式。同時(shí),我們還對(duì)系統(tǒng)的硬軟件進(jìn)行選型和研究,選擇出適合于本系統(tǒng)的硬件系統(tǒng)和軟件系統(tǒng)。 3.在上一小節(jié)嵌入式智能網(wǎng)關(guān)功能結(jié)構(gòu)分析的基礎(chǔ)上,詳細(xì)地描述了以基于ARM11架構(gòu)的處理器S3C6410為核心的智能家庭網(wǎng)關(guān)所涉及到的硬件單元電路的設(shè)計(jì)過程,同時(shí)也介紹了無線通信技術(shù)模塊的硬件結(jié)構(gòu)和設(shè)計(jì)過程。 4.在操作系統(tǒng)的選擇上,本論文中使用ARM-Linux作為嵌入式操作系統(tǒng)。ARM-Linux是一個(gè)開源的、可裁剪的操作系統(tǒng),我們?cè)敿?xì)地描述了Linux的裁剪和移植過程以及引導(dǎo)程序的移植過程。 5.用戶可以通過Web頁面查看家用電器狀態(tài)并且可以發(fā)送命令對(duì)家用電器設(shè)備進(jìn)行遠(yuǎn)程控制。因此,在嵌入式系統(tǒng)設(shè)計(jì)中,我們使用了BOA作為嵌入式服務(wù)器,使用了SQLite作為嵌入式系統(tǒng)的數(shù)據(jù)庫(kù),并且使用了CGI技術(shù)來實(shí)現(xiàn)用戶的信息交互。 截至目前,本設(shè)計(jì)已完成了一個(gè)方便用戶使用的嵌入式智能家庭網(wǎng)關(guān)。在以后的生活中,隨著嵌入式技術(shù)和信息化技術(shù)的不斷成熟,智能家庭網(wǎng)關(guān)也會(huì)得到不斷的更新與完善。
[Abstract]:Advances in science and technology have raised the needs of the general public for family life. How to provide a more concise and convenient life has been puzzling many IT suppliers. With the rapid development of embedded technology and modern information technology, the desire of home intelligence is no longer so remote. We can take every intelligent appliance in the family life as a network node, network each node to form the home network, and make the home network connect with the Internet. In this way, we can send commands and transmit information to the home network through Internet, so that we can control the household appliances. The information interaction between the internal network and the external network is the embedded intelligent home gateway designed in this paper. Intelligent home gateway is a bridge between home network and Internet. It is both the sender and receiver of information. In this paper, the embedded intelligent home gateway has the advantages of small power consumption, small volume, easy to place and move, strong stability and so on. The main contents of this paper are as follows: 1. This paper makes a simple comparison and analysis of the embedded intelligent home gateway at home and abroad, and summarizes the advantages and disadvantages of the existing home gateway at home and abroad. The standards, protocols, and views of home gateways designed by foreign countries are different from those at home. The existing domestic home gateways have large power consumption and large volume, which can not meet the needs of people's family life. At the same time, it emphasizes the urgency of designing a more convenient and fast intelligent home gateway in order to meet the needs of family life. The design of the whole system adopts a top-down design mode. First, the functional analysis of the home gateway to be designed is done, and then the disassembly analysis and design of each functional module are carried out, which is a kind of embedded system design pattern which is widely used now. At the same time, the hardware and software of the system are selected and studied, and the hardware system and software system suitable for the system are selected. 3. 3. Based on the analysis of the function structure of the embedded intelligent gateway in the last section, the design process of the hardware unit circuit involved in the intelligent home gateway based on the ARM11 architecture processor S3C6410 is described in detail. At the same time, it also introduces the hardware structure and design process of wireless communication technology module. 4. In the choice of operating system, this paper uses ARM-Linux as embedded operating system. ARM-Linux is an open source, clippable operating system. We describe in detail the process of Linux clipping and transplanting and the porting process of boot program. 5. Users can view the status of household appliances through the Web page and send commands for remote control of household appliances. Therefore, in the design of embedded system, we use BOA as embedded server, SQLite as database of embedded system, and CGI technology to realize user information exchange. Up to now, this design has completed a user-friendly embedded intelligent home gateway. In the future, with the maturity of embedded technology and information technology, intelligent home gateway will be constantly updated and improved.
