Method for realizing multilane free stream electronic charging through orthogonal phase control array antenna

Abstract

The invention discloses a method for realizing multilane free stream electronic charging through an orthogonal phase control array antenna, and the method comprises the steps that: step 1. vehicle detection and electronic charging transaction; step 2. vehicle position matching and validity verification; and step 3. background data process. In the step 1, a vehicle and road communication and electronic tag locating subsystem receives and scans an uplink signal through an orthogonal phase control radiating unit of the antenna, detects the transverse and vertical migration angles of a vehicle-mounted electronic tag relative to the antenna, and calculates the position of the vehicle-mounted electronic tag, a vehicle detecting and locating subsystem detects the contour of a vehicle, provides station passing time and position information of the vehicle and triggers an image snap-shot procedure, and an image snap-shot and plate number identification subsystem performs image snap-shot and plate number identification of the vehicle; in the step 2, a lane logic coordination control system is used for matching the vehicle-mounted electronic tag position with the vehicle position to find out legal vehicles and illegal vehicles; and in the step 3, a background data processing system performs successive performs following-up processing on a locating matching result in the step 2, an electronic non-parking charging transaction result, and vehicle image snap-shot and plate number identification results.

Description

technical field [0001] The present invention relates to the field of Intelligent Transport System (Intelligent Transport System, referred to as: ITS), relates to a multi-lane free-flow electronic toll collection method, in particular to a multi-lane free-flow electronic toll collection method based on orthogonal phased array antenna positioning. Background technique [0002] At present, many provinces and cities in my country have built electronic toll collection (Electronic Toll Collection, ETC for short) systems on expressways. The existing expressway electronic toll collection system adopts a single-lane mode. Vehicles equipped with on-board electronic tags need to enter the designated lane and pass through the ETC lane at a low speed (the current speed limit of the expressway ETC lane is 20km / h); Vehicles are automatically intercepted by lane railings and processed by manual intervention. The ETC system realizes billing transactions through wireless communication betwee...

AI Technical Summary

Problems solved by technology

The key technical problem in the multi-lane free-flow electronic toll collection system is that since there are vehicles that are not installed or illegally installed with on-board electronic tags, in addition to automatic toll collection for vehicles that are normally installed with on-board electronic tags, it is also required that illegal vehicles can be automatically charged on-site. At present, this is still a technical problem that needs to be solved in the application of multi-lane free-flow electronic toll collection
