Design And Study Of Vehicle Traveling Data Recorder Based On ARM System

Vehicle Travelling Data Recorder (VTDR) is a digital electronic device, which can record vehicle speed, real time, mileage and vehicle's other status information. VTDR is important to hold back traffic peccancies such as tired-driving, overspeed, and it is also important for authenticating and analyzing traffic accident. A whole VTDR system includes two parts, one is the mainframe and the other is the managing and analyzing software.The current VTDR, which mostly adopt 8 bit or 16 bit MCU and assembly language and sinple structure and unitary function, is used in our country. when the embedded technology is widely used in various fields now, in order to the embedded technology is used in VTDR ,which satifies with our national's "Vehicle travelling data recorder"(GB/T 19056-2003)standard and is in line with the international IEEE 1616 standard of "the vehicle traveling data recorder", the VTDR bases on the embedded system is presented in this paper. The VTDR, which takes the 32 bit microprocessor of Samsung's S3C2410 and Linux operation system, has not only been improved systematic real time nature ,but also the function has been managed to expand and enrich.This thesis mainly describes hardware and software designing of VTDR mainframe. VTDR developing background is first introduced. Then domestic and oversea developing actualities are summarized, and based on the summarization the aim of VTDR developing is set forth. In the following part, the thesis discusses the designing conception of the whole system and different plans of each function module. At last, the final designing plan is described in detail.In the system software designing unit, the thesis introduces software developing environment-ARM-Linux across complier. Also, the debugging method and the technological process of each function module are described in detail. Meanwhile, it introduces the process of complile and transplant for Bootloader, Linux operation system and device driver on the S3C2410. In the last chapter, the thesis put forward the summarization and the prospect as the end.
