Fig. 2 is an interaction diagram of an electronic transaction system according to an embodiment of the present application. As shown in fig. 2, the interaction process of the system is as follows:
The V2X roadside unit 521 receives the first vehicle identification and location information from at least one V2X on-board unit 522.
V2X on-board unit 522 carries a unique identity bound to the vehicle, i.e., a first vehicle identity; may be a license plate number or may be a unique identifier that may be obtained by other ETC roadside units 511 and V2X roadside units 521.
A V2X on-board unit 522 is mounted on each vehicle that broadcasts in real time a broadcast information frame carrying at least a first vehicle identification and its location information.
The V2X roadside unit 521 generates lane queue information for each lane according to the first vehicle identification and the position information, the lane queue information corresponding to the lane number, the lane queue information including at least one first vehicle identification, that is, at least one vehicle on the lane.
Specifically, a V2X roadside unit 521 is installed at each toll station for receiving the broadcast information frame of the V2X vehicle-mounted unit 522 and generating lane queue information for each lane using the lane queue capability in the V2X technology. The lane queue information is a vehicle information queue extending toward the coming vehicle direction with the railing machine as a reference point according to the position information of the railing machine and the position information of the vehicles, and the lane queue information contains a first vehicle identification and the position information of each vehicle.
Each toll station is not limited to the installation of 1 set of V2X roadside units 521, and can be adjusted according to practical situations.
A set of ETC road side units 511 is arranged on each lane, and after detecting the ETC vehicle-mounted unit 512, the ETC road side units 511 send a request to the V2X road side unit 521, wherein the request includes the lane number of the lane where the ETC road side unit 511 is located, and is used for requesting lane queue information of the lane corresponding to the lane number.
The V2X roadside unit 521 receives a request from the ETC roadside unit 511, and in response to the request, transmits lane queue information to the ETC roadside unit 511 according to the lane number.
The ETC roadside unit 511 acquires the vehicle identification to be transacted through the ETC vehicle-mounted unit 512; matching each first vehicle identifier in the lane queue information with a vehicle identifier to be transacted; if the matching is successful, the target information is sent to the charging device 513, where the target information includes information of the ETC on-board unit 512 corresponding to the vehicle identifier to be transacted.
Specifically, the ETC roadside unit 511 receives the detected vehicle identifier to be transacted provided by the ETC vehicle-mounted unit 512, and after the ETC roadside unit 511 receives the lane queue information, matches the first vehicle identifier in the lane queue information with the vehicle identifier to be transacted, and if the matching fails, it indicates that the vehicle corresponding to the ETC vehicle-mounted unit 512 detected by the ETC roadside unit 511 is not the vehicle to be transacted in the current lane. If the matching is successful, it indicates that the vehicle corresponding to the ETC on-board unit 512 detected by the ETC roadside unit 511 is a vehicle to be transacted in the current lane, and the ETC roadside unit 511 sends information of the ETC on-board unit 512 of the vehicle to be transacted to the toll collection device 513 to complete the subsequent transaction steps.
Based on the electronic transaction system of the above embodiment, the present embodiment provides an electronic transaction method, which is executed by the ETC roadside unit. Fig. 3 is a flowchart of an electronic transaction method provided in the present embodiment. As shown in fig. 3, the method comprises the steps of:
s11, acquiring a vehicle identifier to be transacted through the ETC vehicle-mounted unit.
The ETC on-board unit carries a unique identification bound to the vehicle, i.e. the second vehicle identification. The ETC road side unit receives a second vehicle identifier from the ETC vehicle-mounted unit, judges whether the second vehicle identifier is in the ETC transacted queue, and if not, confirms that the second vehicle identifier is the vehicle identifier to be transacted.
S12, sending a request to the V2X road side unit.
The request is for instructing the V2X roadside unit to send lane queue information to the ETC roadside unit.
S13, receiving lane queue information from the V2X road side unit.
The V2X on-board unit carries a unique identity, i.e. a first vehicle identity, which is bound to the vehicle. The V2X roadside unit receives first vehicle identification and location information from at least one V2X on-board unit.
The lane queue information is information generated by the V2X road side unit according to the first vehicle identifications and the position information provided by at least one V2X vehicle-mounted unit, and the V2X road side unit sorts the first vehicle identifications of each vehicle from near to far according to the position information of each vehicle and assigns a sorting sequence number. The lane queue information includes at least one first vehicle identification, i.e. at least one vehicle on the lane.
S14, sequentially matching each first vehicle identifier in the lane queue information with the vehicle identifier to be transacted; if the matching is successful, step S15 is executed, otherwise step S11 is executed again.
The lane queue information comprises a serial number of each first vehicle identifier, and each first vehicle identifier in the lane queue information is matched with the vehicle identifier to be transacted in sequence according to the serial number.
The vehicle with the V2X vehicle-mounted unit and the ETC vehicle-mounted unit can be the same identification, such as license plate numbers, or different, but related identifications, such as the equipment number of the ETC vehicle-mounted unit as the first vehicle identification, the equipment number of the V2X vehicle-mounted unit as the second vehicle identification, the equipment number of the ETC vehicle-mounted unit and the equipment number of the V2X vehicle-mounted unit of the same vehicle are both related to the license plate numbers of the vehicles, the association relation is stored in the system, and the system can judge whether the first vehicle identification and the second vehicle identification (or the vehicle identification to be transacted) belong to the same vehicle according to the association relation, if so, the first vehicle identification and the second vehicle identification are considered to be matched.
And if the matching is successful, the vehicle corresponding to the ETC vehicle-mounted unit detected by the ETC road side unit is the vehicle to be transacted of the current lane.
And if the matching fails, indicating the vehicle to be transacted of the non-current lane of the vehicle corresponding to the ETC vehicle-mounted unit detected by the ETC road side unit. And returning to the execution step S11, releasing the link by the ETC road side unit, searching the ETC vehicle-mounted unit again, and acquiring a new vehicle identifier to be transacted.
S15, sending target information to the charging equipment.
The target information comprises information of ETC vehicle-mounted units corresponding to the vehicle identifications to be transacted. The ETC roadside unit sends information of the ETC vehicle-mounted unit of the vehicle to be transacted to the charging equipment so as to complete the subsequent transaction steps.
As a possible implementation manner, in step S11, it may be determined whether the ETC transacted queue is empty according to the queue length or the flag, where the flag is an identifier indicating the status of the ETC transacted queue. If the queue length is zero or the ETC transacted queue is confirmed to be empty through the state of the flag bit, whether the second vehicle identifier is in the ETC transacted queue is not needed to be judged. If the ETC traded queue is not empty, continuing to determine whether the second vehicle identification is in the ETC traded queue.
As a possible implementation manner, before step S14, it is sequentially determined, according to the serial number of each first vehicle identifier, whether the first vehicle identifier in the lane queue information is in the ETC transacted queue. If yes, the vehicle is a vehicle which is already transacted but does not pass through the railing machine, and the lifting rod can be lifted and released at the moment; if not, step S14 is executed to determine whether the first vehicle identifier corresponding to the current serial number is consistent with the vehicle identifier to be transacted.
If the traffic information is consistent, the vehicle is an unhandled vehicle on the lane, and step S15 is executed to send an ETC transaction request to the toll collection equipment; if the ETC transaction conditions are inconsistent, the vehicle is not provided with the ETC transaction conditions, for example, the ETC vehicle-mounted unit is not installed or the ETC vehicle-mounted unit fails, the ETC transaction cannot be completed, and a manual transaction prompt is sent to the charging equipment.
As a possible implementation manner, after step S15, the method further includes: the charging equipment carries out ETC transaction on the corresponding ETC vehicle-mounted unit according to the target information, the ETC road side unit receives the transaction completion message fed back by the charging equipment, updates the information of the ETC vehicle-mounted unit, and writes the vehicle identification to be transacted into the ETC transacted queue. Further, the ETC transacted queue has a fixed length, when a transacted second vehicle identifier is newly added into the queue, the earliest item of identifier information in the queue is correspondingly erased, and the ETC queue is always kept at the fixed length. After the corresponding vehicle passes through the rail machine, it may be removed from the ETC traded queue.
Fig. 4 is a schematic diagram of a matching process according to an embodiment of the present application. As shown in fig. 4, the following is an example:
1. The ETC road side unit acquires a second vehicle identifier A3 from the ETC vehicle-mounted unit, compares the second vehicle identifier A3 with second vehicle identifiers A1 and A2 in the ETC transacted queue respectively, and confirms that the A3 is not matched with the A1 and the A2, and confirms that the A3 is the vehicle identifier to be transacted.
2. The ETC road side unit sends a request to the V2X road side unit, receives lane queue information from the V2X road side unit, obtains 4 first vehicle identifications based on the railing machine assuming that the length of the lane queue B is 5, and sequentially sequences B1, B2, B3 and B4 according to the position information, wherein the fifth bit Null value Null or the default value 0 of the lane queue is assigned.
3. The ETC road side unit compares the first vehicle identification of the lane queue B with the second vehicle identification of the ETC transacted queue in sequence, B1 is matched with A1, B2 is matched with A2, and then the vehicles B1 and B2 are confirmed to be transacted but not passed through the barrier machine, and the vehicle can be lifted and released; b3 and B4 have no matching second vehicle identification in the ETC already-transacted queue, and are vehicles which do not conduct ETC transaction.
4. The ETC roadside unit compares A3 with B3, if the A3 and the B3 are not matched, the B3 is a vehicle without ETC transaction conditions, and manual transaction should be carried out. And the ETC road side unit compares the A3 with the B4, if the A3 is the next vehicle identifier to be transacted in the current lane, and the ETC road side unit sends information of the ETC vehicle-mounted unit corresponding to the A3 to the charging equipment so that the charging equipment can conduct ETC transaction on the ETC vehicle-mounted unit.
5. After the ETC transaction is completed, the ETC roadside unit stores A3 into the ETC transacted queue.
6. And searching a new ETC vehicle-mounted unit by the ETC road side unit, and carrying out transaction judgment of the next round.
The lane queue information is matched with the ETC transacted queue firstly, so that the situation that vehicles in front of the V2X lane queue are transacted and not passed can be eliminated, repeated transaction can be avoided, the lane queue is more strict, and the passing efficiency can be improved better. For example, if the first vehicle in the V2X lane queue is in the ETC transacted queue, the matching and transaction can be continuously performed on the second vehicle in the lane queue, the first vehicle does not need to wait for the first vehicle to pass through the barrier machine, the transaction efficiency is improved, and the quick passing of the vehicles is facilitated.
