Abstract

The invention belongs to the technical field of highway visibility monitoring and discloses a system and a method for monitoring the overall night visibility of a highway network in real time. The system comprises a control center and a plurality of devices for monitoring visibility; each device for monitoring visibility is fixed on a corresponding vehicle; each device for monitoring visibility comprises a video camera, a radar sensor, an ARM processor, a GPS module and a 4G communication module; the video camera is arranged in the center of a front windshield of the vehicle; the radar sensoris arranged in the center of a front bumper of the vehicle and faces towards the forward motion direction of the vehicle; the ARM process is arranged in an engine cabin of the vehicle; the GPS moduleis arranged on the side surface of a steering wheel of the vehicle. The system and the method have the characteristics of small investment, suitability for large-scale popularization, intelligence, automation, no need of operation and high reliability.

Description

technical field [0001] The invention belongs to the technical field of expressway visibility monitoring, in particular to a system and method for real-time monitoring of the overall visibility of an expressway road network at night. Background technique [0002] The visibility of expressways has a direct impact on traffic safety. Low visibility has caused numerous traffic accidents, and also brought huge casualties and property losses, especially at night when low visibility is more likely to occur. From the perspective of expressway safety management, taking different management measures according to different situations of visibility is an important method to ensure the safe passage of expressway at night. For the countermeasures of visibility, no matter what kind of countermeasures, the most important premise is to obtain the data of visibility in order to take targeted countermeasures. [0003] At this stage, the use of visibility sensors is a common method. By fixing ...
