Problems solved by technology

Driving fatigue will affect the driver's attention, feeling, perception, thinking, judgment, will, decision and movement. If you continue to drive the vehicle after fatigue, you will feel drowsy, lethargic, inattention, and decline in judgment. There are even unsafe factors such as trance or instant memory loss, delayed or premature action, operation pause or improper correction time, etc., which are very prone to road traffic accidents. Dangerous drowsy driving state, or knowing that you are driving drowsy but must continue driving for various reasons

Abstract

The invention discloses a driver fatigue detection warning device which comprises a front-end collecting unit, a video processing unit, a biological facial fatigue analyzer, an electronic control unit and an acousto-optic alarm unit, wherein the front-end collecting unit collects facial data of drivers, then the video processing unit processes the facial data and transmits the facial data to the biological facial fatigue analyzer, the analyzed results are performed with signal conversion through the electronic control unit, and the acoustic-optic alarm unit is used for alarming. The driver fatigue detection warning device can effectively warn the drivers in fatigue driving, accordingly the phenomenon of fatigue driving is reduced, and car accidents caused by fatigue driving can be effectively and positively prevented and reduced.

Description

technical field [0001] The invention belongs to the field of safe driving of automobiles, in particular to a driver fatigue detection and early warning device. Background technique [0002] Fatigue driving can be regarded as one of the "road killers". It refers to the disorder of physiological and psychological functions of the driver after driving continuously for a long time, and the phenomenon of objectively declining driving skills. The driver's sleep quality is poor or insufficient. Driving a vehicle for a long time is prone to fatigue. The fatigue of the driver is mainly the fatigue of the nerves and sensory organs, as well as the limb fatigue caused by maintaining a fixed posture for a long time and poor blood circulation. The driver sits on a fixed seat for a long time, and his movements are limited to a certain extent, and his attention is high. Concentration, busy judging the stimulus information outside the car, and high mental state, resulting in blurred eyes, b...
