Description

Method and system for charging vehicles in expressway scene

Technical Field

The application relates to the technical field of expressway charging, in particular to a vehicle charging method and a vehicle charging system in an expressway scene.

Background

The existing highway charging mainly comprises two modes of a semi-automatic lane charging system MTC and an electronic toll collection system ETC, and the specific modes mainly comprise cash, code scanning payment and ETC billing charging.

The application relates to an electronic license plate payment scheme based on a digital RMB hard wallet, which is an upgrade and supplement of the existing payment scheme, can improve the passing efficiency, reduce the fee escaping risk, make up for the short board which can not be used for code scanning and charging under the condition of unstable MTC mode network, and solve the problem of long ETC mode fee settlement period.

At present, the charging mode of the high-speed main stream of the small passenger car mainly comprises an MTC mode and an ETC mode, and the small passenger car is widely popularized in China, and a set of mature communication, monitoring and charging infrastructure and a matched management system are built.

MTC mode, also called manual semi-automatic charging, the specific steps of charging are:

step 1: the MTC vehicle enters a high speed after the rod is lifted through the entrance parking collar clamp;

step 2: in the passing process, the portal frame and the CPC card are communicated based on DSRC technology, so that the 'provincial charging and unified charging' of MTC vehicles are realized "

Step 3: the vehicle needs to stop at the exit, the exit is also blocked, and the lane system calculates the communication fee and informs the vehicle owner.

Step 4: the car owner uses cash or WeChat and pays the bank to pay in real time by scanning the code. And driving away from the high speed after lifting the rod.

The device used in the MTC mode is mainly a highway composite pass card (CPC card for short), has the functions of identifying the information of vehicles entering and exiting a toll station, accurately records the actual driving path of the vehicles, provides important basis for toll fee charging, clearing and the like in a cross-province mode, and mainly comprises a DSRC communication module and a safety module.

ETC mode, is highway automatic charging of not stopping, charge concrete flow:

step 1: when the user handles ETC electronic tags, an ETC high-speed special user card with a PBOC2.0 standard electronic wallet is issued, and the user card is bound with a bank card of the user. And the card is arranged in the vehicle, so that the vehicle can automatically pass into a high-speed road section.

Step 2: when the vehicle is driven into the expressway, the ETC frame can record the coordinates of the vehicle in real time and charge in a segmented way.

Step 3: when the vehicle leaves the ETC high-speed exit, a transaction record is formed, and the deduction transaction of the electronic wallet is triggered.

Step 4: the lane exit is automatically released, and the vehicle owner does not need to park.

Step 5: the highway transaction records are uploaded to the provincial platform through the lane software (the transaction records are uploaded to the local platform if the trans-provincial settlement is involved), and finally the account drawing flow of the high-speed toll is transmitted to the bank, and the bank draws the user high-speed toll to the special account of the road side toll.

The ETC mode main device and principle are that information interaction is realized by utilizing a special DSRC short-range communication technology through a vehicle-mounted electronic tag (OBU) arranged on a vehicle and a Road Side Unit (RSU) arranged on a toll station lane, and corresponding amount is deducted from a pre-bound bank card, so that the purpose of paying without stopping is achieved. The toll collection system can automatically deduct fees without stopping the vehicle at a toll station, and saves a great amount of labor cost.

The MTC mode still has the following problems:

1) When the license plates of the entrance and exit are not matched, the system can directly charge according to the shortest path, and the problem of toll loss exists.

2) To optimize the transaction process of the portal, the transaction success rate of the CPC card is lower than that of the ETC card, the transaction distance is farther than that of the ETC card, and the CPC card is easy to sense by mistake.

3) MTC supports multiple payment modes, cash payment, weChat payment, payment package payment, etc., and in case of poor network conditions, the owner may not be able to pay using an electronic channel, and the user experience is poor.

4) The existing MTC mode owners need to take cards and pay fees at the entrance and the exit, and the passing efficiency and the user experience are affected.

The main problems with ETC networking charging systems are as follows:

1) ETC charging mode has the defect, and in the initial stage of use of the system, because the issuing units cannot audit in place and other factors influence, the situation that the large and small vehicles do not correspond occurs is caused, so that the fee escaping phenomenon is easy to cause, the expressway enterprises suffer from larger economic loss, and the safety problem is easy to cause.

2) The loopholes existing in the operation of the ETC system can be used by lawbreakers in the modes of fake driving license, electronic tag switching, vehicle following and the like to achieve the purpose of fee escaping.

3) The toll settlement period is too long, and after the vehicle owner finishes a journey, the toll is deducted from a bank card bound by the vehicle owner, but the toll is not settled between the expressway and the bank in real time. For provincial peers, the settlement period of the expressway and the bank is about one week, while the settlement of the provincial peers is more than ten days, and the settlement period is too long.
