Method for realizing electronic fee collection on multilane free flow by one-dimension phased array antenna

Abstract

The invention discloses a method for realizing an electronic fee collection on a multilane free flow by a one-dimension phased array antenna, which comprises that step 1: vehicle detection and electronic fee collection transaction, step 2: vehicle position matching and validity verification, and step 3: background data treatment. In step 1, an uplink signal is received and scanned by a vehicle-road communication and electronic tag positioning sub-system with an one-dimension linear array radiation unit of an antenna, an angular offset of the vehicle electronic tag relative to the antenna is detected, the position of the vehicle electronic tag is calculated, a contour of the vehicle is detected by the vehicle detection and positioning sub-system, information on time and position of the vehicle passes a station is provided, and a picture snapping is triggered; and the picture snapping of the vehicle and a number plate identification are carried out by a picture snapping and number plate identification sub-system. In step 2, the positions of the vehicle electronic tag and the vehicle are matched by a lane logic coordination controlling system to find legal and illegal vehicles. In step 3, subsequent treatments are carried out on the result of positions matching in step 2, and the results of the electronic fee collection transaction without vehicles stop, the picture snapping of vehicles and the number plate identification by a background data treatment system.

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 one-dimensional phased array antenna positioning. Background technique [0002] With the continuous increase of expressway mileage and the continuous improvement of toll collection technology, many provinces and cities in my country have established electronic toll collection (ETC) systems for 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.

AI Technical Summary

Problems solved by technology

Although the electronic toll collection system in the single-lane mode has made great technological progress compared with the traditional manual toll collection, it has improved the traffic capacity of the lane, reduced the payment service time, and achieved the effect of energy saving and emission reduction, but there are still high civil construction costs and traffic congestion. The speed is relatively low, and illegal vehicles need to be handled manually on site, etc.
