Vehicle separation detection system for electronic toll collection lane

Abstract

The invention discloses a vehicle separation detection system for an electronic toll collection (ETC) lane. The system at least comprises transaction coils arranged in a transaction communication area, an electronic rail, an ETC doorframe, an ETC platform, and a first group of grating components and a second group of grating components, which are arranged along the direction of the ETC lane, wherein the two groups of grating components are in signal connection with a control system of the ETC platform respectively. According to the vehicle separation detection system, the grating components are used for vehicle separation detection, so that each vehicle in a continuous vehicle stream in the ETC lane can be accurately separated, the order of the vehicles can be accurately bound with an ETC transaction order, the logical mess of the ETC platform can be avoided, and the negative phenomena of vehicle toll evasion, vehicle smashing of the rail, and the like can be substantially completely eradicated.

Description

technical field [0001] The invention relates to the field of transportation electrical technology, in particular to a vehicle division detection system for electronic toll lanes. Background technique [0002] Such as figure 1 As shown, the existing electronic toll lane (ETC) structure mainly involves electronic railing 1, ETC door frame 2, isolation island 3, acousto-optic display device 4, and figure 1 Electronic toll collection platform not shown. figure 1 The middle arrow A indicates the driving direction, and the area B indicated by the dotted line is the transaction communication area. The prior art generally uses loop coils as vehicle detection. When the vehicle enters the transaction communication area B and is sensed by the transaction coil 51, the electronic toll collection platform triggers the charging procedure according to the electronic signals from the transaction coil 51 and the transaction coil 52. [0003] In order to maintain a high success rate of ETC ...

AI Technical Summary

Problems solved by technology

Due to the wrong judgment of the actual number of vehicles entering the ETC lane by the electronic toll collection platform, or because the order of transactions does not correspond to the order of vehicles, the logic of the lane is confused, resulting in toll evasion, and even the phenomenon that the railing smashes the car from time to time.
