Problems solved by technology

Although this method has a certain effect, it not only requires the car owner to bear greater costs, but also the installation of cameras in the car is likely to cause the leakage of the car owner's privacy.

Embodiment

[0098] An embodiment of the present invention provides a highway fatigue driving early warning method, comprising the following steps:

[0099] When the target vehicle equipped with the ETC device drives into the expressway, at the entrance, the vehicle license plate information, the toll station information and time information t 0 Matching is performed, and the matched data is uploaded to the cloud server. Vehicles without ETC devices can realize the above functions by issuing CPC cards;

[0100]There are a large number of ETC gantry installed on the expressway, and the lidar on the gantry continuously collects the speed range of the traffic passing through the gantry; when the target vehicle passes by, the ETC sensing device communicates with the on-board ETC device (or CPC card) , read the information of the target vehicle; the laser radar collects the speed and position information of the target vehicle in real time; the camera collects the license plate information of th...

Abstract

One or more embodiments of the invention provide an ETC portal frame system, a highway fatigue driving early warning method and device, and the method comprises the steps: obtaining the driving track historical information of a vehicle in a highway network; inputting the driving track historical information into an original neural network model, and adjusting the original neural network model to obtain a convergent neural network model; collecting real-time data of the current vehicle; inputting the real-time data of the current vehicle into the convergent neural network model, and predicting the fatigue probability of the driver of the current vehicle; and if the fatigue probability exceeds a threshold value, sending warning information to the current vehicle through a display screen, so that fatigue monitoring of the vehicle during long-distance driving is achieved, operation behaviors of a driver are standardized, traffic safety accidents caused by fatigue driving are avoided, and the driving safety is improved.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of expressway fatigue driving warning technology, in particular to an ETC gantry system, a method and device for expressway fatigue driving warning. Background technique [0002] The road conditions on the expressway are single, and drivers are prone to fatigue. When the driver is tired of driving, there will be a decline in judgment ability, slow response, and operational errors, which can easily lead to traffic safety accidents. [0003] At present, about how to prevent highway drivers from driving fatigue, it is mainly through installing surveillance cameras in the car and collecting relevant information of drivers (such as whether to close their eyes, etc.) to give early warning. Although this method has a certain effect, it not only requires the car owner to bear greater costs, but also arranging cameras in the car can easily cause the leakage of the car owner's privacy. ...
