The Application Of Embedded System In The Vehicle Data Recorder Based On ARM9

It has led to the automobile industry's vigorous development that modern society's economy development and the industry progression,however, the automobile quantity's large growth simultaneously brings one of consequences is the frequent occurrence of traffic accident. What we can do to avoid or the reduce the decrement as far as possible, the vehicle travelling data recorder is one of the answers.The vehicle travelling data recorder is a set of electronic devices which has a collection of functions of data recording, data displaying, illegally alarming, traffic analysising of travelling statement ,it not only can Record and feedback the action of the driver in time,and effectively correct the violation operation of the driver, and provide protection of vehicle security, but also supply first-hand information for the accident analysising after accident occurs, and our country has developed related standards for the device.In this paper, it has designed a new type of vehicle travelling data recorder which based on the embedded systems, the processor has chosen the S3C2410 of ARM9 chip series. S3C2410 is a type of 32-bit processor produced by SAMSANG company,it not only improve the efficiency of the system, but also greatly expanded its functions. In this paper,it also designs its peripherals hardware circuit to play its best performance. As the unceasing enhancement to the performance of the embedded processor, the embedded operating systems is gradually becoming the most important constituent of the embedded systems.In the paper, Refers to the embedded operating system, it applies to the Linux system, through the establishment of cross-compiler tool chain, cutting and compiling of kernel transported the Linux systems to the ARM, the construction of the ARM-Linux platform is complete. In the embedded platform,it set up the entire hardware system, including data acquisition module, data display module, power module .etc and analysis it in-depth. Finally, the system software has been designed, including the preparation of the bottom of the bottom driver and the top application flow chart and GUI of the recorder.
