基于arm_linux的商业移动智能信息终端研究与设计word格式论文.docxVIP

摘要本文针对连锁专柜的现状，密切结合商户的需求，设计了一个基于 ARM_LINUX 的商业智能信息终端。商户可以在终端上完成基本的商品零售、库存盘点、会员管理等 功能。其机型小巧、功能紧凑、物美价廉、联网方便、操作方便、易学易用，是企业总 部与销售门店间数据交互的好帮手。本文首先分析了课题研究背景及终端产品的研究现状与发展动态，说明了课题的来 源并给出了终端系统的组织架构。然后根据信息终端的设计需求构建了终端的硬件系统 总体设计框架，出于模块化的考虑，根据功能和结构，分别设计了核心板电路、主板电 路、GPRS 通讯板电路、触摸按键板电路、指示灯板接口电路、条码扫描模块接口电路 等。随后,对嵌入式 Linux 系统进行移植，包括 U-Boot 的移植；Linux 内核的配置、编 译和移植；Linux 文件系统的制作、移植等工作。接着对 MiniGUI 设计的图形用户界面 做了介绍,详细介绍了信息终端的业务流程。最后对对信息终端的核心板硬件、主板硬 件、触摸按键硬件、GPRS 模块、条码扫描模块进行了测设和验证。此外，还对信息终 端整体性能进行了测试。测试结果完全满足当初的设计需求。信息终端已经成功在某连锁专柜试运行成功。运行结果反馈表明，信息终端运行可 靠稳定。为适应科技的飞速发展和技术的快速革新，信息终端的后续研究将选用 3G 网 络进行通讯，人机交互采用电容屏，提升用户体验。关键词：ARM9，智能信息终端，嵌入式 Linux 系统，图形界面，MiniGUIABSTRACTBased on the status of the chain store, the intelligent consumption information terminal is designed according to the demands of businesses. Businesses can complete the basic commodities retail, inventory management, member management and other functions. It is a good helper for the data exchange between corporate headquarters and sale stores because it has compact function, inexpensive, convenient networking, easy to operate, easy to use and other advantages.The paper first analyzes the research background and the dynamic of terminal product research and development, describes the source of the topic, and presents the structure of terminal system. An overall framework of the terminal hardware system is built according to the design requirements of the information terminal. For modular reason, we design the core circuit, motherboard circuit, GPRS communication circuit, touch button circuit, indicator interface circuit and bar code scanning module interface circuit according to the function and structure. Subsequently, we transplant the embedded Linux system, including U-BOOT transplantation, configuration of the Linux kernel, compile and transplantation, production, transplantation of the Linux file system. Then the paper introduces the graphical userinterface which is designed to use MiniGUI. Finally, the paper test an
