With the popularity of vehicle, driving recorder has widely used in automobile. In this paper,a kind of driving recorder based on wireless communication is introduced, solves the problem of reading data in large station. First, system of vehicle data recorder is introduced. Then, the hardware interface and the design form is mainly proposed, and its soft- ware structure, software flow, recorder management software and its application is also introduced. Finally, the experi- ence and effect of vehicle data recorder are summarized. The user＇s feedback shows that recorder is stable; data is con- venient to read, and management software operation reliable, especially suitable for large station to use.
