Abstract: This paper designs an intelligent vehicle traveling data recorder based on embedded
system and the state standards—GB/T19056-2003. It presents the basic functions and framework of the recorder，and then describes its project of hardware and software. The combination of ARM7 and uC/OS-II have many advantages, for example, the former decreases power consumption of the system, and the later provides a good platform for programming.
Key words: Embedded system, data recorder, ARM7, uC/OS-II
