A method and system for discriminating the lane position of moving vehicles based on vehicle electronic identification

Abstract

The invention discloses a method and system for discriminating the lane position of a moving vehicle based on an electronic vehicle identification. The method includes: capturing in real time the signal from the electronic identification of a moving vehicle according to a preset radio frequency signal through a plurality of signal antennas arranged above multiple lanes. The reflected signal sent out; the signal antenna corresponds to the lane one by one; the reflected signal is demodulated into two orthogonal I / Q signals through orthogonal demodulation; the correspondence is calculated according to the two orthogonal I / Q signals The phase information of the reflected signal; calculate the phase difference corresponding to the reflected signal at two adjacent moments captured by each of the multiple signal antennas; compare the phase difference corresponding to each of the multiple signal antennas, and determine according to the signal antenna The lane where the vehicle is located; the method and system have high environmental applicability, further monitor the lane position of a specific vehicle through the uniqueness of the vehicle electronic identification, and provide direction for future traffic management.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, to a method and system for discriminating the lane position of a moving vehicle based on a vehicle electronic identification. Background technique [0002] Vehicle electronic identification is equivalent to the vehicle's ID card, and is being promoted nationwide, which is conducive to the management of vehicles by traffic control departments, especially the identification of illegal activities such as traffic violations and fake / duplicated license plates. Install vehicle electronic identification reading and writing equipment at expressway intersections or traffic monitoring intersections; [0003] In the existing traffic management system, the monitoring of vehicles is mainly through continuous photographing of the same vehicle, and then through image recognition and other technologies to confirm the specific location of the vehicle, and to identify the specific informati...

Problems solved by technology

[0004] In order to solve the problem existing in the background technology that the existing method of identifying vehicles by image recognition technology and then judging the location of the vehicle cannot be effectively monitored under special circumstances or when the vehicle intentionally avoids, the present invention provides a vehicle electronic based A method and system for discriminating the lane position of a marked moving vehicle. The method and system confirm the identity of the vehicle by identifying the electronic sign of the vehicle, and solve the difficulty of image recognition of the vehicle in special circumstances; further obtain the vehicle through communication with the electronic sign. The position of place lane; Described a kind of real-time speed measuring method of moving vehicle based on vehicle electronic identification comprises:
