Fatigue driving warning method and device

Abstract

The invention discloses a fatigue driving warning method and device, and the method comprises the steps: 1, collecting a brain wave signal of a driver in real time through a brain wave sensor, and collecting the facial features of the driver in real time through an image sensor; 2, whether the driver is in a fatigue driving state or not is judged and detected on the basis of the collected brain wave signals and facial features of the driver; and step 3, if the driver is judged to be in the fatigue driving state, uploading the state of the driver to a service desk, notifying the driver of parking and resting by a telephone of the service desk, and giving out an alarm sound through an audio module to warn the fatigue driver. The fatigue state of a driver is collected and judged through the image sensor and the brain wave sensor, the fatigue driver is intervened and warned through alarm sound sent by the audio module, motor vibration and fan blowing, meanwhile, the state of the driver is uploaded to a service desk, and the driver is urged to have a rest or warned that driving safety risks exist at present through a telephone of the service desk.

Description

technical field [0001] The invention relates to the field of fatigue detection, in particular to a fatigue driving warning method and device. Background technique [0002] Fatigue driving is a major factor that affects driving safety. Fatigue driving refers to the phenomenon that the driver's physiological and psychological functions are out of balance after driving continuously for a long time, resulting in a decline in driving skills. There are many reasons for fatigue. For example, the driver’s sleep quality is poor or insufficient, and the road conditions are better, resulting in monotonous road conditions. If you continue to drive the vehicle after fatigue, you will feel drowsy, sleepy, weak in limbs, inattentive, and poor in judgment. There are unsafe factors such as slow or premature movements, operation pauses, etc., which are very likely to cause road traffic accidents. [0003] Most of the existing fatigue driving reminders are through voice reminders or light ala...

There are many reasons for fatigue. For example, the driver’s sleep quality is poor or insufficient, and the road conditions are better, resulting in monotonous road conditions. If you continue to drive the vehicle after fatigue, you will feel drowsy, sleepy, weak in limbs, inattentive, and poor in judgment. There are unsafe factors such as slow or premature movements, operation pauses, etc., which are very likely to cause road traffic accidents

[0003] Most of the existing fatigue driving reminders are through voice reminders or light alarms. The existing fatigue driving methods cannot effectively stimulate the driver to wake up and excite, and drive safely to a place where he can rest
