Design Of Control Platform For Embedded Detection System Based On ARM9

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.
