Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle payment, and in particular relates to a vehicle-related payment device. Background Art

[0002] Considering that there may be multiple different travel paths between the starting point and the end point of a trip, in order to facilitate the highway toll collection system to identify the actual travel path of the vehicle, the existing system deploys a gantry system on the road section. The gantry system communicates with the on-board DSRC electronic tag, including writing relevant information such as the road section name and travel time into the DSRC electronic tag. When the vehicle arrives at the exit, the toll collection system reads the vehicle's travel path information from the DSRC electronic tag and calculates the actual toll.

[0003] Currently, there are two main types of DSRC electronic tags. One is the on-board unit (OBU) of the ETC electronic toll collection system, which is fixed on the windshield of the vehicle. One ETC vehicle is equipped with a fixed OBU electronic tag. The other is the CPC temporary pass card issued to non-ETC vehicles at the entrance. The CPC temporary pass card contains a DSRC communication module and an NFC short-range communication module. When the vehicle is driving, the gantry system of the section writes the section information to the OBU or CPC card through DSRC communication. When the vehicle arrives at the exit, the roadside unit RSU deployed in the ETC dedicated lane reads the OBU through DSRC communication. The toll is calculated based on the path information recorded by the vehicle. In order to release the vehicle quickly, the vehicle is released first, and the corresponding highway toll is deducted from the bank account bound to the license plate number afterwards. For non-ETC vehicles, the CPC composite temporary pass card is manually collected at the toll exit. The lane equipment reads the path information recorded in the CPC card through NFC communication. The toll is calculated based on the path information actually traveled by the vehicle. The user presents the payment QR code of WeChat, Alipay and other APPs, and the lane system scans the payment QR code. After deducting the toll from the corresponding payment institution, the gate is opened to release the vehicle.

[0004] The existing technical architecture of highways makes the user account systems in each province relatively independent, and real-time fee deductions cannot be achieved through cross-provincial networking. Even for users within the same province, real-time settlement is difficult to achieve because data needs to be forwarded between the provincial settlement center and the lane system through the road section center, and the provincial settlement center has a large transaction volume. Summary of the invention

[0005] The purpose of the present invention is to provide a vehicle-related payment device, which aims to solve the technical architecture of existing highways. The user account systems between provinces are relatively independent, and real-time deduction of fees cannot be achieved through cross-provincial networking; even for users within the province, data forwarding between the provincial settlement center and the lane system still needs to be carried out through the section center, and the provincial settlement center has a large transaction volume, making it difficult to achieve real-time settlement.

[0006] The present invention is implemented as follows: a vehicle-related payment device, which includes: a vehicle-related application core module, the vehicle-related application core module is connected to an NFC near-field communication module, a DSRC dedicated short-range communication module and a satellite positioning module, the vehicle-related application core module is used to save vehicle license plate information and record vehicle driving path information, the DSRC dedicated short-range communication module is used to interact with highway entrance and exit roadside units and gantry systems, the NFC near-field communication module exchanges data with smart mobile terminals, and the satellite positioning module is used to receive navigation satellite signals. The vehicle-related payment device has four payment modes, namely soft wallet payment mode, hard wallet payment mode, satellite positioning payment mode and free-flow vehicle-related payment mode.

[0010] When the vehicle is traveling on the highway, the highway gantry system equipment writes the vehicle's driving path to the vehicle-related payment device through DSRC communication;

[0011] When the vehicle arrives at the highway exit, the DSRC reader / writer at the highway exit reads the information in the vehicle-related payment device, calculates the toll of the vehicle, and sends a payment confirmation instruction to the vehicle-related payment device;

[0012] The highway toll is displayed through the display module. After the user authorizes, the corresponding payment confirmation instruction is returned to the DSRC reader / writer at the highway exit. The highway toll collection system deducts the highway toll from the digital RMB wallet corresponding to the license plate number bound to the user, opens the exit gate, and releases the vehicle.

[0013] Preferably, when the hard wallet payment mode is executed, when the vehicle arrives at the highway entrance, the DSRC reader / writer at the highway entrance reads the license plate number of the vehicle-related payment device and writes the vehicle entry site name and time to the vehicle-related payment device;

[0016] The highway toll is displayed through the display module. After the user authorizes, the core module of the vehicle-related application executes the payment instruction after receiving the user's confirmation, and returns the corresponding payment data. The highway toll system deposits the digital RMB corresponding to the payment data into the toll company's public digital currency wallet, opens the exit gate, and releases the vehicle.

[0017] Preferably, when the satellite positioning payment mode is executed, when the vehicle arrives at the entrance of the expressway, the DSRC reader / writer at the entrance of the expressway reads the license plate number and writes the name and time of the vehicle entry site to the vehicle-related payment device;

[0018] When the vehicle is traveling on the highway, the vehicle-related payment device obtains satellite signals through the satellite positioning module on time and records the vehicle's driving path;

[0020] The highway toll is displayed through the display module. After the user authorizes, the corresponding confirmation information is returned. The highway toll system deducts the corresponding amount of digital RMB from the digital RMB wallet corresponding to the license plate number; the highway toll system opens the exit gate and releases the vehicle.

[0021] Preferably, when the free-flow vehicle-related payment mode is executed, when the vehicle arrives at the entrance of the expressway, the expressway toll collection system records the license plate number, the vehicle entry site name and time preset by the vehicle-related payment device;

[0022] When a vehicle is traveling on a highway, the vehicle-related payment device obtains satellite signals through a satellite positioning module on time, calculates the vehicle's driving path, and sends corresponding location information to the highway toll collection system;
