【摘要】 检测系统是现代工业中常用的设备，本文在深入研究嵌入式系统的基础上，进行基于ARM9的嵌入式检测系统控制平台设计，充分利用ARM9芯片内部集成的丰富资源与嵌入式设备体积小、成本低、易集成的特点，将该平台与检测系统相结合，以此来实现对检测系统的控制及数据的采集。该平台主要包括硬件电路设计、引导程序U-boot的移植、Linux操作系统的裁剪与移植以及嵌入式文件系统的建立，并进行了部分单元功能测试和性能分析。首先，在分析国内外研究状况和深入了解ARM嵌入式系统的基础上，进行嵌入式控制平台总体设计。根据低功耗、高性能、易携带等性能要求确立平台的核心处理器和软件系统。处理器芯片采用三星公司基于ARM920T内核的S3C2410，操作系统采用源码开放、内核可裁剪的Linux。其次是硬件电路的设计，包括处理器和外围电路设计，充分利用处理器芯片集成的丰富内部资源，并引出多个外围设备接口，方便进行二次开发和使用。然后，针对控制平台硬件配置进行软件设计，分析了Linux内核移植要点并给出移植的详细流程，完成了引导加载程序U-boot和Linux2.6内核代码的裁剪、配置、编译和移植，并利用Busybox工具进行根文件系统及Cramfs文件系统的创建和移植。硬件和软件的设计完成后，搭建了基于该平台的图像采集系统，通过开发符合V4L标准的USB摄像头驱动程序，编写压缩和存储函数接口，实现了图像的采集、显示和数据存储，并对该控制平台进行部分功能测试和性能分析。测试结果表明，软硬件都可以正常工作，达到了预期的设计要求。更多还原

【Abstract】 Detection system is widely used in modern industry, this paper designed a controlplatform for embedded detection system based on ARM9 after deeply studying of embeddedsystem. In order to manipulate the detection system and realize data collection, the richresources integrated inside ARM9 chip and advantages of embedded equipments, such assmall size, low cost and easy to integrate, were fully utilized. The platform mainly includeddesign of hardware circuit, transplantation of U-boot, cutting and transplantation of Linux andestablishment of embedded file system. After that, partial function tests and performanceanalysis were completed.First of all, overall designe of embedded control platform was made on the analysis ofdomestic and foreign research situation and further study of ARM embedded system. Thecore processor and software system of platform were established by the requirements of lowpower consumption, high performance and easy to carry. Samsung’s S3C2410 chip wasselected as core processor, which used ARM920T as kernel. And open-source Linux wasselected as operating system. Secondly, hardware circuit including processor and peripheralcircuit was designed, which was rich in internal resources. And peripheral device interfaceswere drew out for secondary development. Thirdly, software was designed according to theconfiguration of hardware, transplantation points of Linux kernel was analyzed and detailedtransplant procedure was gave out. Meanwhile，clipping, configuration, compiling andtransplantation of U-boot and Linux2.6 kernel were completed. Finally root and Cramfs filesystem were created by Busybox tools.After designs of hardware and software, an image acquisition system based on theplatform was set up. Image collection, display and data storage were realized through thedevelopment of USB camera driver conforming to V4L, compression and storage interfacefunction. Finally, partial function tests and performance analysis were completed. The results showed that hardware and software can work normally and the designe has achieved expectedperformance requirements.更多还原
