Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0022] like figure 1 As shown, the embodiment of the present invention provides a vehicle network road condition monitoring system for two-way eight-lane traffic flow monitoring, which includes a vehicle position acquisition unit located at the intersection, and the two lanes are respectively the first lane and the second lane. Vehicles on the lanes and roads are respectively equipped with GPS positioning units. When the distance between the vehicle position acquis...

Abstract

The present invention provides a vehicle networking road condition monitoring system. The road vehicles are respectively equipped with GPS positioning units. When the distance between the vehicle position acquisition unit and the GPS positioning unit on the vehicle is lower than the set threshold, the GPS positioning unit The vehicle position data is sent to the vehicle position acquisition unit; the two lanes respectively include two straight lanes in the middle, a left-turn lane on the far left, and a right-turn lane on the far right, and the vehicle position data includes The number of vehicles on each lane on the two roads where the intersection is located, and the vehicle position data is sent to the road condition analysis unit to output vehicle condition information. The present invention can effectively monitor the traffic flow of the lanes in all directions near the intersection, and judge whether it is congested or unblocked according to the traffic flow after the confluence of each lane, because whether the road section is congested mainly depends on the number of vehicles at the intersection and the circulation The road condition of the road section obtained through the intersection traffic information is more accurate.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a road condition monitoring system for the Internet of Vehicles. Background technique [0002] Intelligent transportation is the development trend of modern traffic management. Vehicle monitoring technology is one of the key technologies of intelligent transportation system. Accurately obtaining vehicle driving direction, traffic flow and other information through vehicle monitoring technology is an important basis for real-time grasp of traffic information and auxiliary traffic management. . [0003] Current Vehicle Monitoring Technology [0004] Video vehicle monitoring technology is a relatively commonly used vehicle monitoring technology. By analyzing video images of traffic scenes to identify changes between consecutive pictures, the purpose of vehicle monitoring is achieved. However, when the light is poor at night, the images collected by the video capture...
