Fatigue driving state recognition prewarning system and method

Abstract

The invention discloses a fatigue driving state recognition prewarning system which comprises a central processing unit, a vehicle state sensor, a loudspeaker, an intelligent bracelet, intelligent glasses and a displayer. The vehicle state sensor, the loudspeaker and the displayer are connected with the central processing unit through cables, the central processing unit is used for acquiring processing information indicating whether a driver is in a fatigue state currently or not according to collected driver vehicle running parameters, physiological signals and eye movement features, the vehicle state sensor, the intelligent bracelet and the intelligent glasses are used for transmitting collected information to the central processing unit, and the loudspeaker and the displayer are used for broadcasting and displaying real-time information. The invention further discloses a fatigue driving state recognition prewarning method. Through detection and recognition of fatigue state of the driver and real-time feedback of fatigue degree, convenience is brought to the driver to timely take measures, so that scientific and reasonable prewarning is provided to the driver, traffic accidents caused by fatigue driving are reduced, and traveling reliability of the driver is improved.

Description

technical field

[0001] The present invention relates to road vehicle operation safety, in particular to a fatigue driving state identification and early warning system and method, which can effectively identify the driver's current fatigue driving state, and then give a scientific and reasonable early warning to the driver in a dangerous driving state, thereby Prevent traffic accidents caused by fatigue. Background technique

[0002] In recent years, with the continuous increase of the number of motor vehicles in our country, the incidence of traffic accidents has increased rapidly, and the problem of road traffic safety has gradually become one of the focuses of people's attention. Analysis of the causes of road traffic accidents found that the accidents caused by drivers themselves accounted for more than 85%, and fatigue driving was one of the main reasons for drivers to cause accidents.
