【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。
[Abstract]:Detection system is a common equipment in modern industry. Based on the research of embedded system, this paper designs the control platform of embedded detection system based on ARM9. Taking full advantage of the rich resources integrated in ARM9 chip and the characteristics of small size, low cost and easy integration of embedded equipment, the platform is combined with the detection system to realize the control of the detection system and the collection of data. The platform mainly includes hardware circuit design, the transplanting and transplanting of boot program U-boot and the establishment of embedded file system, and some unit function tests and performance analysis are carried out. Firstly, on the basis of analyzing the domestic and international research situation and deeply understanding the embedded system of ARM, the overall design of embedded control platform is carried out. The core processor and software system of the platform are established according to the requirements of low power consumption, high performance and easy to carry. The processor chip is based on the ARM920T kernel S3C2410, the operating system is open source, the kernel can be cut Linux. Secondly, the design of hardware circuit, including the design of processor and peripheral circuit, makes full use of the rich internal resources of processor chip integration, and leads out several peripheral device interfaces, which is convenient for secondary development and use. Then, the hardware configuration of the control platform is designed, the main points of Linux kernel porting are analyzed and the detailed flow of the porting is given. The clipping, configuring, compiling and transplanting of the boot loader U-boot and Linux2.6 kernel code are completed. The root file system and Cramfs file system are created and transplanted by Busybox tool. After the design of hardware and software, the image acquisition system based on the platform is built. By developing the USB camera driver which conforms to the V4L standard, the interface of compression and storage function is compiled, and the image acquisition, display and data storage are realized. Part of the function test and performance analysis of the control platform are carried out. The test results show that the software and hardware can work normally and meet the expected design requirements.
