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 invention provides an Internet of vehicles road condition monitoring system. A vehicle on the road is separately provided with a GPS positioning unit. When the distance between a vehicle position acquiring unit and the GPS positioning unit on the vehicle is shorter than a preset threshold value, the GPS positioning unit transmits vehicle position data to the vehicle position acquiring unit. Two lanes separately include two straight lanes in the middle, a left turning lane on the far left and a right turning lane on the far right. The vehicle position data includes the number of vehicles on each lane of the two lanes where an intersection is, and the vehicle position data is transmitted to one road condition analyzing unit and the road condition information is output. According to the invention, the system can effectively monitor traffic of the lanes in each direction in the vicinity of the intersection, and according to the traffic flow after the convergence of each lane, determines whether the road is jammed or not. Since whether the road is jammed is determined by the number of vehicles and congestion conditions at the intersection, road conditions obtained from traffic information at the intersection 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...
