Abstract

The invention provides a DMS driver fatigue pre-warning system, which includes a camera, a processor, an alarm module and a speed limiting module. The camera is installed in a cab, and used for collecting human face images of drivers and transmitting the collected human face images to the processor through electrical signals; the processor is used for calculating the driving time of the drivers, and when the driving time exceeds a predetermined threshold, fatigue signals are sent to the alarm module and the speed limiting module; the alarm module provides sound and / or visual alarms to the drivers after receiving the fatigue signals; and the speed limiting module limits the driving speed of vehicles after receiving the fatigue signals. According to the DMS driver fatigue pre-warning system,the driving time of the drivers is calculated through human face recognition and / or fingerprint recognition, the alarm module and the speed limiting module are used for guiding the drivers to take arest regularly, a human-machine interaction module is used for determining whether the drivers are tired or not, the method is simple and effective, and the cost is also low.

Description

technical field [0001] The invention relates to the field of safe driving, in particular to a DMS driver fatigue warning system. Background technique [0002] Driving fatigue refers to the decreased level of response produced after a period of driving. Slow response, slow judgment and slow rhythm are the main manifestations of driver fatigue. Fatigue driving is an important factor leading to traffic accidents. The number of road traffic casualties in my country ranks first in the world every year, and it is increasing at a rate of 10% per year. Traffic accidents caused by fatigue driving are also increasing at a very fast rate. Fatigue driving has become an important factor in traffic accidents, seriously threatening people's lives and property safety. [0003] With the rapid development of intelligent technology, car driving is also developing in the direction of intelligence, safety and simplification. The development of car intelligence, safety and simplification has gr...
