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

Abstract

The invention belongs to the technical field of traffic safety, and discloses a device and method for real-time reminding of road sections of fog at night 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 moving toward the vehicle The radar sensor of the direction, 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 end of the camera is connected with the first signal input end of the ARM processor, and the radar sensor The signal output end is connected with the second signal input end of the ARM processor, the signal output end of the GPS module is connected with the third signal input end of the ARM processor, the signal output end of the ARM processor is connected with the signal input end of the 4G communication module, The signal output terminal of the 4G communication module is connected to 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 method for reminding a foggy road section at night by using an electronic map in real time. Background technique [0002] Fog is the natural enemy of highway operation safety, and it is often accompanied by heavy casualties in traffic accidents, especially at night, it is more difficult for drivers to find fog. The time, location, and size of the fog are often random, and the fog moves around. For highways at night, the traffic conditions between the foggy sections are good, and the speed of the vehicle is usually high. When the vehicle suddenly enters the foggy road section, the visibility suddenly drops from several kilometers to less than 200 meters, even dozens of meters, and even less than ten meters, which is fatal to the vehicle during operation. Many serious traffic accidents occurred in our country due to mass fog, most of which occurred...

AI Technical Summary

Problems solved by technology

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

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