Design of the vehicle driver fatigue monitor system based on ARM

Fatigue driving is refers to the driver in a long time continuous driving or physical fatigue condition, and then come into being physiological and psychological function disorder, led to a decline in driving ability. Aimed at the requirements of monitoring on the fatigue driving, this article designed an driver fatigue monitor system based STM32F407 of ARM as a controller, it used to determine the driver's fatigue and reduce the traffic accident. The system adopts the method of multi-source information fusion, by monitoring the pulse, heart rate, temperature of the human body, steering wheel grip strength to realized the fatigue level. The system of graphical interface adopts UCGUI. Finally, testing the main function modules of early warning system, verify the feasibility of the proposed early warning system.
