Embodiment Construction

[0039] The following will describe in detail with reference to the accompanying drawings in conjunction with the embodiments, so as to further explain the technical features and advantages of the present invention.

[0040] Method flow chart of the present invention is as figure 1 As shown, a method for preventing fatigue driving based on a smart bracelet, the smart bracelet has a built-in gravity sensor and a timer, and the method includes four steps of S1-S4.

[0041] Step S1 of the present invention is: setting the time threshold for the smart bracelet to be still and the threshold for the smart bracelet to deviate from the steering wheel. S1 mainly uses the gravity sensor of the smart bracelet to prevent fatigue driving. The gravity sensor works according to the principle of piezoelectric effect, and can obtain the moving distance of the object through the three-dimensional coordinate system established by itself, which is the feasible basis of the present invention. In t...

Abstract

The invention discloses a fatigue driving prevention method and a system based on an intelligent hand ring. The intelligent hand ring is internally provided with a gravity sensor and a timer. The method comprises steps that, S1, a time threshold value of the intelligent hand ring for being static and a threshold value of the intelligent hand ring for deviating from a steering wheel are set; S2, whether the intelligent hand ring generates displacement or not is acquired in real time; S3, if the intelligent hand ring does not generate displacement, a timer switch is triggered to start timing, when timing arrives the time threshold value of the intelligent hand ring for being static, alarm is triggered; and S4, if the intelligent hand ring generates displacement, a distance of the intelligent hand ring for deviating from the steering wheel is detected in real time, when the distance of the intelligent hand ring for deviating from the steering wheel arrives the threshold value of the intelligent hand ring for deviating from the steering wheel, alarm is triggered. The fatigue driving prevention method can effectively prevent users from driving in a fatigue state, driving safety is further improved, user experience is improved, structure change of vehicle steering wheels is not needed, and cost is reduced.

Description

technical field [0001] The invention relates to the application technology of smart bracelets, in particular to a method and system for preventing fatigue driving based on smart bracelets. Background technique [0002] A smart bracelet is a wearable smart device. Through smart bracelets, users can record real-time data such as exercise, sleep, and some diets in daily life, and synchronize these data with mobile phones, tablets, and ipod touch, and play a role in guiding healthy life through data. [0003] Fatigue driving is one of the important factors causing traffic accidents in real life, therefore, traffic accidents caused by fatigue driving occur from time to time. In traffic accidents, some cars rushed out of the green belt and drove into the roadside ditch, and some cars directly collided with obstacles. Most of these are caused by fatigue driving. Prior art all realizes by transforming motor vehicle driver's seat. This will increase the cost to a certain extent. ...
