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 the expressway road network. The system includes a control center and a plurality of visibility monitoring devices, and each visibility monitoring device is fixed on Corresponding to the vehicle, each device for monitoring visibility includes: a camera installed in the center of the front windshield of the vehicle, a radar sensor installed in the center of the front bumper of the vehicle and facing the forward direction of the vehicle, and an ARM processor installed in the engine compartment of the vehicle , the GPS module installed on the side of the steering wheel of the vehicle, and the 4G communication module; it has the characteristics of low investment, suitable for large-scale promotion, intelligence, automation, no 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. 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...
