Vehicle relative position judgment method based on directional antennas

Abstract

The invention discloses a vehicle relative position judgment method based on directional antennas. The directional antennas are arranged on the two sides of a vehicle head, the two sides of a vehicle tail and the two sides of a vehicle body respectively, and get away from the vehicle body to be arranged outwards. The method comprises the steps that the antennas broadcast wireless signals comprising vehicle unique identification information outwards and meanwhile monitor wireless signals existing around, and converge the received signals to a vehicle terminal in real time; the vehicle terminal processes the obtained data information; the relative position of a vehicle is determined through the RSSI of the multiple groups of antennas. The method can take full advantage of the character of on-board equipment in the internet of vehicles, obtains a visual vehicle relative position conclusion through data analysis of the on-board equipment, better adapts to the character of the internet of vehicles, and can accurately and rapidly judge the relative position of the vehicle.

Description

technical field [0001] The invention belongs to the technical field of Internet of Vehicles, and in particular relates to a method for judging the relative position of a vehicle based on a directional antenna. Background technique [0002] The concept of the Internet of Vehicles (Internet of Vehicles) is derived from the Internet of Things (Internet of Things). The definition means that the electronic tags loaded on the vehicles use radio frequency and other identification technologies to realize the attribute information and static, A system that extracts and effectively utilizes dynamic information, effectively supervises the operating status of all vehicles and provides comprehensive services according to different functional requirements. However, there are still some problems in the research on the relative position of vehicles in the current Internet of Vehicles research. First, the relative position determination of the existing Internet of Vehicles relies too much o...

AI Technical Summary

Problems solved by technology

First, the relative position determination of the existing Internet of Vehicles relies too much on the on-board camera. However, the installation position of the on-board camera is relatively fixed, and it is impossible to obtain a 360-degree view around the vehicle. At the same time, the processing speed of the image information obtained by the on-board camera cannot meet the application requirements.

Second, other Internet of Vehicles technologies can only judge the presence of vehicles around them, but have no ability to judge the location of the vehicle relative to itself
