Embodiment 1

[0023] According to an embodiment of the present invention, a roadside unit system for reducing the cost of ETC lane construction is provided. The system includes a radio frequency identification unit, a vehicle detection unit, and a main control unit; the radio frequency identification unit is used to The vehicle-mounted unit on the passing vehicle communicates, and obtains the passing information of the current vehicle to be passed from the vehicle-mounted unit; and the radio frequency identification unit is also used to detect the distance between the vehicle-mounted unit of the current vehicle to be passed and the roadside unit system to obtain the first A distance value; after the currently waiting vehicle enters the ETC lane, the vehicle detection unit measures the distance between the roadside unit system and the current waiting vehicle based on the preset ranging model to obtain the second distance value; The control unit matches the first distance value detected by the ...

Embodiment 2

[0045] According to the embodiment of the present invention, there is also provided a roadside unit system for reducing the cost of ETC lane construction, such as figure 1 As shown, it is a schematic structural diagram of a roadside unit system for reducing the construction cost of ETC lanes according to Embodiment 2 of the present invention.

[0046] Such as figure 1 As shown, the roadside unit system for reducing the construction cost of ETC lanes provided by Embodiment 2 of the present invention includes a 5.8 GHz radio frequency identification unit, a main control unit, a vehicle detection unit, and a power supply unit.

[0047] The functions of each unit of the roadside unit system provided by Embodiment 2 of the present invention are as follows:

[0048] The 5.8GHz radio frequency identification unit is responsible for communicating with the OBU, obtaining vehicle information (model information), entrance information, and route information from the OBU, and completing deductions...

Embodiment 3

[0058] According to Embodiment 3 of the present invention, a schematic flow diagram of an embodiment of the roadside unit system to prevent interference from following the car is also provided. Pass as figure 2 The processing flow shown can achieve RSU to prevent interference with the car.

[0059] The specific processing flow is as follows:

[0060] The vehicle enters the ETC lane;

[0061] The radio frequency identification unit obtains the vehicle information in the OBU / the vehicle detection unit detects the position of the vehicle;

[0062] The main control unit roots the number of vehicles in the ETC lane and the location of the vehicle to determine whether the current OBU can be traded. If it is judged that the current OBU can be traded, the transaction will continue and the fee-deduction pass will be completed; if it is judged that the current OBU cannot be traded, then Terminate the communication, prompting impassable.

Abstract

The invention discloses a roadside unit system capable of reducing the construction cost of an ETC lane. A radio frequency identification unit is used for detecting a distance between the onboard unitof a current vehicle to pass and the roadside unit system so as to obtain a first distance value; after the current vehicle to pass enters the ETC lane, a vehicle detecting unit measures the distancebetween the roadside unit system and the current vehicle to pass based on a preset distance measurement model so as to obtain a second distance value; and a main control unit matches the first distance value detected by the radio frequency identification unit with the second distance value detected by the vehicle detecting unit, and determines whether an automatic deduction transaction is to be performed on the current vehicle to pass according to a preset matching rule, and performs automatic deduction transaction on the current vehicle to pass after the distance values satisfy the preset matching rule. With the roadside unit system of the invention adopted, the construction cost of the ETC lane is reduced, and the stability of the ETC lane is also improved.

Description

Technical field [0001] The invention relates to the technical field of expressway non-stop toll collection, and in particular to a roadside unit system for reducing the construction cost of ETC lanes. Background technique [0002] At present, in the electronic toll collection (Electronic Toll Collection, ETC) lanes, in order to avoid following interference, it is necessary to lay ground-sensing coils on the ETC lanes. The position of the ground-sensing coils and the road side unit (RSU) are collected. The information (including time, coordinates, etc.) of the on board unit (OBU) is combined with the various information received above to make corresponding logical judgments to determine whether there is a car following phenomenon in the ETC lane. [0003] Since the ground induction coil laying requires construction on the ground of the ETC lane, the coil and the vehicle detector that cooperates with the ground induction coil need to be laid, which makes the construction of the ETC l...
