A New Vehicle Traveling Data Recorder Based on Embedded System

This is the research report of a new vehicle traveling data recorder. It includes the technical requirements, difficulties, and solutions of the new vehicle traveling data recorder based on 32 bit embedded processor and uCLinux operating system. After picking an existing development plat form, we debugged and improved the software and hardware many times. Compared with the traditional products which is based on 8 bit MCS51 chip microcomputer, the new recorder can record the velocity and other work conditions of the vehicle integrally, precisely, and diversifiedly. In the report, the author puts forward and advances method to design the computer control system, and gets good experimental results.
