Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0040] Such as figure 1 As shown, a method for preventing ETC lane following interference, comprising the following steps:

[0041] (1) The lane controller obtains the first license plate number stored in the on-board unit OBU of the current vehicle entering the ETC channel;

[0042] (2) the lane controller acquires the second license plate number of the current vehicle through license plate capture and recognition, and the second license plate number is the license plate number suspended by the vehicle;

[0043] (3) The lane controller compares whether the first license plate number is consistent with the second license plate number;

[0044] (4) If they are consistent, open the stopper to let the current vehicle pass, otherwise close the stopper to prevent the current vehicle from passing.

[0045] In this embodiment, when the vehicle equi...

Abstract

The present invention relates to a method and system for preventing ETC lane behind car interference. Whether a released car and a payment car are consistent or not can not be accurately determined by an existing method. According to the method / system of the invention, the first license plate number stored by the vehicle-borne OBU unit of a current car which enters into an ETC lane through a lane controller; the lane controller obtains the second license plate number of the current car, the second license plate number is the suspended license plate number of the car; the lane controller compares whether the first license plate number and the second license plate number are consistent or not; if so, a car stop is opened is release the current car, otherwise the car stop is closed to stop the pass of the current car. By using the method and the system, the consistence of the released car and the payment car can be determined, and the wrong charges can be avoided.

Description

technical field [0001] The invention belongs to the field of electronic non-stop charging, and in particular relates to a method and system for preventing ETC lane following interference. Background technique [0002] Expressway non-stop toll collection refers to the electronic payment of tolls through the microwave communication link established by the on-board unit (OBU) in the vehicle and the roadside unit (RSU) on the lane gantry when the vehicle passes through the ETC lane arranged by the toll station. technical means. [0003] In practical application, the problem of following-vehicle interference often occurs, resulting in inconsistencies between toll-paying vehicles and releasing vehicles. For example, when two vehicles drive into the ETC lane, if the front car is not equipped with an OBU or the sensitivity of the OBU is lower than that of the rear car, the transaction of the rear car is successful, but the front car does not have a transaction. Vehicles are allowe...
