【摘要】：随着我国社会和经济的发展,广告日益成为企事业单位进行自我宣传的重要手段。嵌入式广告机的出现,标志着广告从单一的大众型宣传变得更具有多样化和针对性。但目前大多数广告机的设计模式都比较单一,因此如何设计一个好的广告机终端以满足某些市场客户的需求,已经成为广告机市场一个新的课题。本文有针对性的根据现有市场上广告机的终端设计模式,设计了一种可以自定义样式并采用多种升级方式的,符合市场需求的广告机终端。主要完成的工作包括了硬件,系统软件和应用软件三大模块的分析与设计。本文根据广告机硬件的需求,对S3C6410处理器的硬件平台进行了分析,并且具体研究了网卡控制器和SD控制器的相关硬件设计。在硬件平台的基础上,本文实现了对系统软件平台的搭建,包括bootloader的移植分析,Linux内核的剪裁,文件系统的建立,以及相关驱动的分析和设计。本文的重点是结合framebuffer驱动及其工作原理,实现基于帧缓冲设备的API接口；结合XML技术,将其应用到广告机终端的设计中,并在此基础上提出将XML与数据库相结合并应用于广告机设计的思想；设计基于网络和USB接口的两种软件资源升级方式；完成终端显示模块和socket网络应用的设计以及mplayer播放器的移植。项目开发经过前期的选题、市场调研、技术分析等阶段,最终实现了以嵌入式S3C6410为处理器,以联网发布式为前提的广告机软件终端的设计。现已成功运用于整个联网发布式广告机项目的产品中。实践证明,该广告机终端设计方案的实用价值比较高,运行效果良好。图29表0参48
[Abstract]:With the development of our society and economy, advertising has become an important means for enterprises and institutions to publicize themselves. It symbolizes that advertising has become more diversified and targeted from a single mass type of propaganda. However, most advertising machines have a relatively single design pattern at present, so how to design a good advertising machine terminal to meet the needs of some market customers, Has become an advertising machine market a new topic. According to the terminal design pattern of advertisement machine in the existing market, this paper designs a kind of advertisement machine terminal that can customize the style and adopt a variety of upgrade methods, which meets the market demand. The main work accomplished includes hardware. Analysis and design of three modules of system software and application software. In this paper, the hardware platform of S3C6410 processor is analyzed according to the hardware requirement of advertisement machine, and the related hardware design of network card controller and SD controller is studied in detail. This paper realizes the construction of system software platform, including the transplantation analysis of bootloader kernel, the establishment of file system, and the analysis and design of related drivers. The emphasis of this paper is to realize the API interface based on frame buffer device by combining the framebuffer driver and its working principle, and to apply it to the design of advertising machine terminal with the combination of XML technology. On this basis, this paper puts forward the idea of combining XML with database and applying it to the design of advertisement machine, and designs two kinds of software resource upgrade methods based on network and USB interface. The design of terminal display module and socket network application and the transplantation of mplayer player are completed. The project has been developed through the stages of early selection, market research, technical analysis and so on. Finally, the embedded S3C6410 is used as the processor. The design of the software terminal of the advertisement machine based on the Internet publishing mode has been successfully applied to the product of the whole project of the online advertising machine. The practice has proved that the practical value of the design scheme of the terminal of the advertisement machine is relatively high. Good results. Fig. 29, table 0, refs. 48
