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.
