Fatigue driving monitoring system and method based on brain waves

Abstract

The invention discloses a fatigue driving monitoring system and method based on brain waves. The monitoring system comprises a head-wearing brain wave signal collection device, a brain wave analyzer and a warning controller; the head-wearing brain wave signal collection device comprises multiple groups of electrode sensors, the brain wave analyzer comprises a pre-amplifier circuit, a band-pass filter circuit, an A / D conversion circuit and a main control chip, and the main control chip is connected with the warning controller. The monitoring method comprises the following steps that 1, brain wave signals are collected; 2, the signals are amplified and then subjected to filter processing; 3, all paths of the brain wave signals are combined into one path; 4, the combined signals are subjected to A / D conversion and then input into the main control chip; 5, the main control chip judges that a driver is in a fatigue driving state, and a warning signal is sent to the warning controller. Accordingly, fatigue driving can be monitored accurately, the reliability is high, warning can be conducted on the driver and surrounding vehicles simultaneously, and the warning effect is better.

Description

technical field [0001] The invention relates to the technical field of fatigue driving detection, in particular to a brain wave-based fatigue driving monitoring system and monitoring method. Background technique [0002] With the development of the transportation industry in recent years, the number of automobiles in cities has increased, and the number of automobile traffic accidents has increased year by year. And because of the continuous improvement of the comfort and performance of motor vehicles, good highway driving conditions, high driving speed and other gradually optimized environmental factors, drivers are more likely to unconsciously enter the fatigue driving state of micro-sleep. Although the micro-sleep state generally only lasts for 2-3 seconds, for a vehicle traveling at high speed, it can rush a distance of tens of meters during this period, causing tragic traffic accidents. [0003] Fatigue driving is a serious traffic violation. When the driver is tired, ...
