The invention belongs to the technical field of expressway visibility monitoring, and discloses a system and method for real-time monitoring of the overall visibility of an expressway network. The system comprises a control center and a plurality of visibility monitoring devices, each visibility monitoring device is fixed on a corresponding vehicle, and each visibility monitoring device comprisesa camera mounted in the center of front windshield of the corresponding vehicle, a radar sensor mounted in the center of a front bumper of the corresponding vehicle and facing the vehicle heading direction, an ARM processor mounted in an engine compartment of the corresponding vehicle, a GPS module mounted on the side face of a steering wheel of the corresponding vehicle, and a 4G communication module. The system has the advantages of low investment, no need of operation and high reliability, and is suitable for large-scale promotion, intelligentization and automation.
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. Background technique [0002] The visibility of expressways has a direct impact on traffic safety. Low visibility has caused numerous traffic accidents and brought huge casualties and property losses. 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 expressways. 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 the visibility sensor on the side of the highway, the optical principle is used to colle...
