Device and method for prompting night agglomerate fog road section in real time by employing electronic map

Abstract

The present invention belongs to the technical field of the traffic safety, and discloses a device and a method for prompting night agglomerate fog road section in real time by employing an electronicmap. The device comprises: a camera installed at the center of a front windshield of a vehicle, a radar sensor installed at the center of a front bumper of the vehicle and arranged towards the direction of forward motion of the vehicle, an ARM processor installed at a vehicle engine compartment, and a GPS module installed at the side of a vehicle instrument panel, and a 4G communication module. The signal output end of the camera is connected with the first signal input end of the ARM processor, the signal output end of the radar sensor is connected with the second signal input end of the ARMprocessor, 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 endof the 4G communication module, and the signal output end of the 4G communication module is in communication connection with an electronic map server. The device and the method for prompting night agglomerate fog road section in real time by employing an electronic map are little in input, is suitable for large-scale generalization, is intelligent and automatic, does not need operation and is high in 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 real-time reminding of foggy road sections at night by using an electronic map. Background technique [0002] Fog is the natural enemy of expressway operation safety, and it is also a state that is often accompanied by traffic accidents with heavy casualties, especially at night, it is not easy to be discovered by drivers. The timing, location, and size of fog blobs tend to be random, and the blobs move around. For highways at night, 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. There have been many serious traffic accidents d...

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
