【摘要】：在IT領(lǐng)域,每十年會有一次變革,會給全球的商業(yè)帶來巨大的連鎖反應(yīng)。信息技術(shù)的又一次重大變革----云計算,它是一種繼網(wǎng)格計算后的新型計算模式,具有強大的數(shù)據(jù)存儲能力和數(shù)據(jù)業(yè)務(wù)處理能力,并且還具有經(jīng)濟性和共享性等優(yōu)點。因此,面向云計算模式的嵌入式數(shù)據(jù)終端必然會受到個人消費者的青睞。 本文通過分析目前云計算的現(xiàn)狀和未來發(fā)展趨勢,針對目前個人移動數(shù)據(jù)終端存在的存儲能力有限、數(shù)據(jù)傳輸效率低和資金利用率低等問題,提出了面向云計算模式的嵌入式數(shù)據(jù)終端解決方案。本文的主要研究內(nèi)容如下： (1)介紹了云計算的基本理論,闡述了云計算的服務(wù)模式,總結(jié)了云計算的特點,簡要介紹了3G網(wǎng)絡(luò)的發(fā)展現(xiàn)狀,重點研究了云計算的體系結(jié)構(gòu)。 (2)著重介紹了嵌入式系統(tǒng)相關(guān)知識,重點分析了目前移動數(shù)據(jù)終端存在的主要問題、運營瓶頸以及未來移動數(shù)據(jù)終端的發(fā)展方向,結(jié)合3G無線網(wǎng)絡(luò)通信模塊,提出了基于云計算的嵌入式數(shù)據(jù)終端解決方案,并對3G無線網(wǎng)絡(luò)通信過程進行了分析以及向嵌入式Linux內(nèi)核添加了3G模塊驅(qū)動,實現(xiàn)了客戶端與服務(wù)器端3G無線網(wǎng)絡(luò)通信。 (3)深入研究了網(wǎng)絡(luò)文件系統(tǒng)(NFS),并在虛擬機上成功安裝NFS服務(wù)器,把虛擬機作為仿真云服務(wù)器。研究了嵌入式Linux開發(fā)技術(shù),構(gòu)建了基于ARM9的嵌入式Linux開發(fā)平臺,搭建了交叉編譯環(huán)境。 (4)研究了基于IP網(wǎng)絡(luò)的數(shù)據(jù)傳輸技術(shù),設(shè)計了客戶端(Client)與服務(wù)器端(Server)程序,實現(xiàn)了基于云計算的嵌入式終端系統(tǒng)仿真模型。 最后,利用搭建的硬件平臺和軟件平臺,在客戶端實現(xiàn)了對服務(wù)器端文件的讀寫操作,通過Socket程序?qū)崿F(xiàn)了客戶端圖片上傳以及下載服務(wù)器端圖片,仿真結(jié)果表明達到預(yù)期目標,并且整個嵌入式數(shù)據(jù)終端成本也較低。
[Abstract]:In IT, there is a change every ten years, which has a huge chain effect on global business. Cloud computing is another important change in information technology. It is a new computing mode after grid computing. It has powerful data storage capacity and data business processing ability, and also has the advantages of economy and sharing. Therefore, the embedded data terminal for cloud computing mode will be favored by individual consumers. By analyzing the current situation and future development trend of cloud computing, this paper aims at the problems of limited storage capacity, low efficiency of data transmission and low utilization of funds in personal mobile data terminals. An embedded data terminal solution for cloud computing mode is proposed. The main research contents of this paper are as follows: (1) the basic theory of cloud computing is introduced, the service mode of cloud computing is expounded, the characteristics of cloud computing are summarized, and the development status of 3G network is briefly introduced. In this paper, the architecture of cloud computing is studied, and the related knowledge of embedded system is introduced. The main problems of mobile data terminal, the bottleneck of operation and the developing direction of mobile data terminal in the future are analyzed. Combined with 3G wireless network communication module, this paper puts forward the solution of embedded data terminal based on cloud computing, analyzes the 3G wireless network communication process and adds 3G module driver to embedded Linux kernel. In this paper, 3G wireless network communication between client and server is realized. (3) the network file system (NFS) is deeply studied, and NFS server is successfully installed on the virtual machine, and the virtual machine is used as the simulation cloud server. The embedded Linux development technology is studied, the embedded Linux development platform based on ARM9 is constructed, the cross-compiling environment is built. (4) the data transmission technology based on IP network is studied, and the client and server programs are designed. The embedded terminal system simulation model based on cloud computing is implemented. Finally, using the hardware platform and software platform, the server files are read and written in the client, and the client pictures are uploaded and downloaded through socket program. The simulation results show that the desired goal is achieved. And the cost of the whole embedded data terminal is lower.
