Fatigue driving preventing device

Abstract

The invention discloses a fatigue driving preventing device. The fatigue driving preventing device comprises a fatigue predicting module, a face information identifying module, a face information judging module and an inner alarming module. When the anti-fatigue driving device is used, the fatigue predicting module can conduct active prediction on a driver at intervals, and sends out fatigue test signals if conditions are met; the face information identifying module collects face information parameters and conducts analysis and contrast on the face information parameters and preset fatigue parameters through the face information judging module; if alarm sending-out conditions are met, the inner alarming module sends out an alarm to the driver. The fatigue driving preventing device does not need to be hung on the driver, so that subjective rejecting emotions of the driver are avoided. Besides, the fatigue predicting module is arranged in advance, and whether the driver is fatigued or not can be tested irregularly in the whole driving process of the driver, so that leakage judgment is reduced. Moreover, a pre-judging module and the judging module are simultaneously arranged, so that double insurance is achieved, and the probability of misjudgment is reduced. Finally, irregular monitoring is adopted, fatigue monitoring is not continually conducted in the whole driving process, so that resources are greatly saved, and requirements for devices are lowered.

Description

technical field [0001] The invention relates to the field of electronic systems, in particular to an anti-fatigue driving device. Background technique [0002] Fatigue driving is one of the main causes of traffic fatal accidents. The statistics of traffic accidents in many countries show that more than 20% of accidents that cause personal injury or even death are caused by fatigue driving. [0003] Existing a kind of anti-fatigue tool that is used for automobile is the alarm that hangs on the ear, and its method of use is to require the driver to hang this alarm on the ear in the process of driving a motor vehicle. As long as there is a head-down behavior during driving, the alarm will sound an alarm to remind the driver that he is already in a state of fatigue. [0004] The alarm device provided by the above-mentioned prior art has at least the following defects: firstly, the driver is usually not willing to hang the alarm device on the ear subjectively; , Fatigue does n...

Problems solved by technology

[0004] The alarm device provided by the above-mentioned prior art has at least the following defects: firstly, the driver is usually not willing to hang the alarm device on the ear subjectively; , Fatigue does not necessarily cause head-down behavior, and head-down behavior is not necessarily fatigue. This generalization method is likely to cause misjudgment or missed judgment; finally, if the head-down is caused by dozing off, forecasting after bowing the head may be ineffective. too late
