Embodiment Construction

[0047] One of the inventive ideas of the present invention to solve the problems described in the background technology is to monitor the physiological information of the driver in real time during the driving process by wearing a smart bracelet for the driver, and obtain the driver's fatigue degree according to the vehicle driver's fatigue degree evaluation model According to the quantified value of the fatigue degree, the pre-warning action is executed according to the quantified value of the fatigue degree, and at the same time, the driver of the vehicle and the drivers of other vehicles driving on the road are given a pre-warning, which further reduces the probability of a car accident due to fatigue driving.

[0048] The inventor determined three physiological indicators of electrocardiogram, electromyography, and blood oxygen saturation by consulting relevant literature and multiple experiments. The inventor designed a subjective questionnaire based on the sleepiness scale...

Abstract

The invention provides a commercial vehicle driver fatigue early warning method based on a smart bracelet. The method can monitor and early warn fatigue driving behaviors of a driver. The method comprises the following steps: obtaining physiological information of a user; obtaining fatigue level information of the user according to the physiological information of the user; and executing an earlywarning action according to the fatigue level information of the user. According to the invention, early warning is carried out on a driver of the vehicle and drivers of other vehicles running on theroad through the warning light outside the vehicle through the wristband, and the driver of the vehicle and the drivers of other vehicles can take corresponding actions in time after receiving the alarm, so that the probability of traffic accidents caused by fatigue driving is further reduced.

Description

technical field [0001] The invention relates to the field of transportation, in particular to a method for early warning of driver fatigue of commercial vehicles based on a smart bracelet. Background technique [0002] In recent years, with the popularization of automobiles, the number of urban automobiles has increased year by year, accompanied by serious problems such as frequent road traffic accidents, among which traffic accidents caused by fatigue driving account for a considerable proportion. Especially for passenger drivers of large commercial vehicles and freight drivers of long-distance driving, if a traffic accident occurs, the impact will be immeasurable. At present, the fatigue driving detection technology based on driver behavior characteristics and vehicle behavior characteristics has problems such as difficulty in feature extraction, low detection accuracy, and susceptibility to environmental factors, resulting in inability to provide timely and accurate feedb...
