Problems solved by technology

[0005] (1) If there is no ETC lane next to the toll lane, but an MTC (Manual Toll Collection artificial semi-automatic toll collection) lane, then if a vehicle equipped with an on-board unit travels on the MTC lane, there will be a phenomenon of trading instead of trading
As a result, the user is deducted more money
[0006] (2) If two ETC lanes are adjacent to each other, the transaction may fail due to the simultaneous execution of two roadside unit transactions, or two repeated transactions will be repeatedly deducted
Therefore, the existing solutions for roadside unit antenna design still have many disadvantages

Embodiment 1

[0040] Please refer to figure 2 The signal processing flow of the non-stop toll collection service shown includes the sending and receiving flow. The ETC system in this embodiment mainly includes two equipment units: a roadside unit and an on-board unit. Wherein each toll lane is provided with a roadside unit. In this embodiment, there are a plurality of adjacent toll lanes, and the vehicle is provided with an on-board unit. After the vehicle enters the toll lane, the transaction should be realized with the road side unit according to the design requirements. Adopt realization method of the present invention, concrete realization process is as follows:

[0041] Step 11, adding the identification information of the adjacent roadside unit to the current roadside unit.

[0042] Step 12, the roadside unit sends a signal with the identification information of the adjacent roadside unit to the vehicle-mounted unit that enters the coverage area of ​​the roadside unit.

[0043] S...

Embodiment 2

[0047] Please refer to image 3 The flow of the vehicle-mounted unit transaction processing process shown specifically includes the following processing process:

[0048] Step 21, the vehicle-mounted unit receives the BST signal from the roadside unit, and the vehicle-mounted unit records the transaction time of the current transaction and the equipment identification (BeaconID) of the current lane and the adjacent lane.

[0049] Step 22, the on-board unit judges whether the RSU is the same as the RSU of the last transaction according to the equipment identification information in the BST signal, if they are the same, go to step 25, otherwise go to step 23.

[0050] In steps 23 and 24, the vehicle-mounted unit judges whether the roadside unit is the same as the adjacent roadside units of the roadside unit in the last transaction according to the equipment identification information in the BST signal. If they are the same, go to step 25 and go to step 27.

[0051] Step 25, ass...

Abstract

The invention discloses a method for sending an electronic toll collection (ETC) service signal, a method for receiving the ETC service signal, a road side unit and a vehicle-mounted unit. Identification information of an adjacent road side unit is added into the road side unit, the vehicle-mounted unit acquires the identifier of the adjacent road side unit when receiving a beacon service table (BST) signal so as to determine which ones are the adjacent side units, and the original transaction time interval for only judging the road is modified to be the transaction time interval for judging both the road and the adjacent road during judgment of the transaction interval; therefore, the problem of repeat transaction caused by the influence of the adjacent road is solved.

Description

technical field [0001] The invention relates to an ETC (Electronic Toll Collection non-parking toll collection) service, in particular to a technology for realizing the ETC service when a plurality of toll lanes are adjacent to each other. Background technique [0002] The relevant equipment specification part of the network toll collection technical standard of the Ministry of Communications specifically stipulates the ETC business. This standard is mainly used in expressways to realize non-stop toll collection. The standard mainly stipulates two equipment specifications of the on-board unit (OBU On-Board Unit) and the roadside unit (RSU Road-Side Unit), and specifies the short-range communication protocol (DSRC Dedicated Short Range Communication). Among them, the roadside unit is set in the toll lane, and the on-board unit is installed inside the vehicle, and adopts a two-piece label scheme. The advantage of the ETC business is that it can reduce energy consumption and a...
