A vehicle-road communication test system based on 5G antenna

Abstract

The invention discloses a vehicle-road communication test system based on a 5G antenna, which includes a vehicle-mounted detection terminal, a road traffic data platform, and a test management service platform. The road traffic data platform includes a number of traffic data acquisition terminals, a vehicle-road communication connection module, and a traffic data analysis Module and data release early warning module. The present invention tests the communication conditions among vehicles, roads, and road traffic control centers to screen out the best communication conditions, and improves the mutual communication and transmission data between vehicle-mounted detection terminals, traffic data acquisition terminals, and road traffic control centers. Accuracy, reduce data loss and delay, realize real-time information interaction, and can analyze the minimum speed of the vehicle corresponding to the lane change risk coefficient less than the set safety threshold and the time required for lane change, and can accurately Evaluate the feasibility and risk of vehicle lane change, reduce the risk of vehicle lane change, and realize the convenience of vehicle-road communication.

Description

technical field [0001] The invention belongs to the technical field of vehicle-road communication, and relates to a vehicle-road communication test system based on a 5G antenna. Background technique [0002] With the rapid development of my country's road transportation industry, the number of cars has continued to grow, and cars have become an indispensable means of transportation in people's lives. Traffic safety problems, traffic safety accidents cause national economic losses and casualties, which seriously affect people's daily life. [0003] Traffic accidents caused by speeding and changing lanes account for the largest proportion of traffic accidents. As a strategic emerging industry, the Internet of Things can ensure smooth road traffic communication and provide communication between roads and vehicles. However, the existing communication technology is in the process of vehicle-road communication. There are problems such as serious packet loss and delay, which seriou...

Problems solved by technology

[0003] Traffic accidents caused by speeding and lane changes account for the largest proportion of traffic accidents. As a strategic emerging industry, the Internet of Things can ensure smooth road traffic communication and provide communication between roads and vehicles. There are problems such as serious data packet loss and delay, which seriously affect the timeliness of data transmission and the integrity of data packet transmission in the vehicle-road communication process, hinder the development of the field of vehicle-road communication, and thus cannot provide the best solution in a timely manner according to the vehicle-road conditions. Road warning reminders and guidance, etc., and the communication conditions in the vehicle-to-road communication process cannot be screened out according to the vehicle-to-road communication test, and the existing vehicles cannot quantitatively evaluate the lane-changing risk coefficient while driving on the road, resulting in the risk of vehicle lane-changing High, unable to provide intelligent early warning reminders for vehicle traffic based on vehicle-road communication
