A device and method for real-time reminder of foggy road section by using electronic map

Abstract

The invention belongs to the technical field of traffic safety, and discloses a device and method for real-time reminder of foggy road sections by using an electronic map, comprising: a camera installed in the center of the front windshield of the vehicle, installed in the center of the front bumper of the vehicle and facing the forward direction of the vehicle The radar sensor, the ARM processor installed in the engine compartment of the vehicle, the GPS module installed on the side of the vehicle dashboard, and the 4G communication module; the signal output terminal of the camera is connected to the first signal input terminal of the ARM processor, and the signal of the radar sensor The output end is connected to the second signal input end of the ARM processor, the signal output end of the GPS module is connected to the third signal input end of the ARM processor, the signal output end of the ARM processor is connected to the signal input end of the 4G communication module, and the 4G The signal output terminal of the communication module communicates with the electronic map server, which has the characteristics of low investment, suitable for large-scale promotion, intelligent, automatic, no operation and high reliability.

Description

technical field [0001] The invention belongs to the technical field of traffic safety, and in particular relates to a device and a method for real-time reminder of foggy road sections by using an electronic map. Background technique [0002] Fog is the natural enemy of highway operation safety, and it is also a state that is often accompanied by traffic accidents with heavy casualties. The timing, location, and size of fog blobs tend to be random, and the blobs move around. For expressways, traffic conditions between sections of foggy roads are good, and vehicle speeds are usually high. When the vehicle suddenly enters the foggy road section, the visibility suddenly drops from several thousand meters to less than 200 meters, even tens of meters, and what is even worse may reach less than ten meters, which is fatal to the running of the vehicle. Many serious traffic accidents have occurred in our country because of the fog, which has caused serious social consequences. [...

AI Technical Summary

Problems solved by technology

[0003] Fog cannot be misreported and cannot be controlled. It is feasible to use visibility sensors to monitor road visibility, but the highway mileage is so huge that it is obviously impossible to install visibility sensors on every road section.

Therefore, apart from educating drivers how to deal with it safely, there is no specific technical means to identify the fog phenomenon at this stage.
