Research on Driver Fatigue Early Warning Method Based on ARM

摘要

Fatigue driving is one of the important reasons of road traffic accidents,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. In order to overcome the limitation of single sensor in the fatigue test,aimed at the requirements of monitoring on the fatigue driving,this article designed an driver fatigue monitor system based ARM926EJ-S as a controller,it is used to determine the driver’s fatigue and reduce the traffic acc ident. On the basis of fully considering the source correlation and complementary,it 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,the feasibility of the proposed early warning system is verified fusion.
