Bad driving habits vehicle traveling data recorder use, fatigue driving, speeding and so the driver can act as a restraint on the safe driving support vehicles, and has an important role in the analysis and identification of Accidents. The design based on the STM32 designed a vehicle traveling data recorder, mainly STM32F103 microcontroller as the main control unit to the camera module OV7670 image acquisition module to your SD Card data storage module. Control systems at certain intervals to collect the camera module to capture image data, and store real-time collection of images, we can insert the SD card to the computer side of the system in real time and store the captured image information view. In addition, through the serial data transmission system monitoring tool for real-time, making the abstract data acquisition, data storage, data call image becomes more specific. The design of the car recorder with a real-time, high reliability, and cost characteristics.
