Description

Technical Field

[0001] This invention relates to the field of ETC intelligent toll collection technology, and in particular to an ETC transaction method, apparatus, device and storage medium based on multicast sharing. Background Technology

[0002] When ETC (Electronic Toll Collection) vehicles pass through highway toll lanes, due to crosstalk of DSRC (Dedicated Short Range Communication) signals, transactions may be mistakenly triggered by the RSU (Road Side Unit) in adjacent lanes, resulting in wrong release or wrong blocking, thus affecting the order of the toll lane.

[0003] In the existing toll station system, because each lane system is independent of the others, real-time data sharing cannot be achieved. Interference between adjacent lanes leads to vehicle reversing and congestion, which not only reduces the travel experience for drivers, but also poses a serious challenge to the operation and management of highways. Summary of the Invention

[0004] This invention provides an ETC transaction method, apparatus, device, and storage medium based on multicast sharing, to achieve cross-lane matching and release information synchronization of ETC transaction data and license plate recognition data between multiple lanes.

[0006] When a vehicle is detected entering the lane license plate recognition area, the license plate recognition device collects the license plate recognition associated data of the vehicle and sends the license plate recognition associated data to the lane control host.

[0007] The lane control host filters out candidate transaction data that matches the time sequence of the license plate recognition data from the locally stored ETC transaction data, matches the transaction license plate in the candidate transaction data with the recognized license plate, and sends a release or interception command to the lane barrier machine according to the matching result.

[0008] When the lane control host sends the release command, it generates release notification data and encapsulates it into a release notification multicast frame.

[0009] According to another aspect of the present invention, an ETC transaction device based on multicast sharing is provided, the device comprising:

[0010] The license plate recognition module is used to collect the license plate recognition associated data of the vehicle through the license plate recognition device when a vehicle is detected entering the lane license plate recognition area, and send the license plate recognition associated data to the lane control host.

[0011] The instruction sending module is used by the lane control host to filter out candidate transaction data that matches the time sequence of the license plate recognition data from the locally stored ETC transaction data, match the transaction license plate in the candidate transaction data with the recognized license plate, and send a release or interception instruction to the lane barrier machine according to the matching result.

[0012] The release notification module is used to generate release notification data and encapsulate it into a release notification multicast frame when the lane control host sends the release command.

[0013] According to another aspect of the present invention, an electronic device is provided, the electronic device comprising:

[0014] At least one processor;

[0015] and memory that is communicatively connected to at least one processor;

[0016] The memory stores a computer program that can be executed by at least one processor, which enables the at least one processor to execute the ETC transaction method based on multicast sharing according to any embodiment of the present invention.

[0017] According to another aspect of the present invention, a computer-readable storage medium is provided, which stores computer instructions for causing a processor to execute and implement the multicast-shared ETC transaction method of any embodiment of the present invention.

[0018] The technical solution of this invention addresses technical problems such as transaction and lane mismatch and vehicle misinterpretation caused by adjacent lane interference by generating release notification data and encapsulating it into a release notification multicast frame when a vehicle enters the lane license plate recognition area. This achieves the technical effects of improving ETC passage efficiency and reducing misjudgments due to adjacent lane interference.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0026] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0027] Figure 1 This is a flowchart illustrating an ETC transaction method based on multicast sharing, provided as an embodiment of the present invention. This embodiment is applicable to ETC transaction scenarios. The method can be executed by an ETC transaction device based on multicast sharing. This device can be implemented in hardware and / or software and can be configured in an electronic device. Figure 1 As shown, the method specifically includes the following steps:

[0028] S110. When a vehicle is detected to have entered the lane license plate recognition area, the license plate recognition device collects the license plate recognition associated data of the vehicle and sends the license plate recognition associated data to the lane control host.

[0029] Multicast sharing can be understood as a method of information sharing where multiple devices join the same data transmission group, and data sent by one device can be received by all devices in the group. ETC transaction method can be understood as a method of collecting vehicle tolls using an electronic non-stop toll collection system. Lane license plate recognition area can be understood as a specific area on a lane where license plate recognition equipment is installed to capture and recognize vehicle license plates. License plate recognition equipment can be understood as equipment that can obtain vehicle license plate information through image capture and recognition technology. License plate recognition associated data can be understood as data related to vehicle license plates collected by the license plate recognition equipment, including the recognized license plate and recognition time. Lane control host can be understood as controlling various devices on the lane, such as barrier gates and recognition equipment.

[0030] Specifically, when a vehicle enters the license plate recognition area of ​​the lane, the license plate recognition device will identify the vehicle's license plate, collect license plate recognition-related data including the identified license plate, recognition time, and recognition reliability, and send this data to the lane control host.

[0031] Optionally, before detecting that a vehicle has entered the lane license plate recognition area, the following steps are also included:

[0032] Initialize and configure the antenna equipment, license plate recognition equipment and control host of each ETC lane in the toll plaza, and connect the multiple lane control hosts after initial configuration to the same multicast group to build a multicast network.

[0033] In this context, a toll plaza can be understood as an area with multiple toll lanes for vehicles to stop and pay fees. Antenna equipment can be understood as devices installed in ETC lanes for wireless communication with the vehicle's onboard unit. Initial configuration can be understood as the initial settings for device parameters and network configuration before the system runs. A multicast group can be understood as a group of multiple devices established to enable multicast communication. Multicast networking can be understood as building a network structure that enables multicast communication, allowing devices within the group to transmit data.

[0034] Specifically, before a vehicle enters the license plate recognition area, initial parameter settings must be configured for the antenna equipment, license plate recognition equipment, and control hosts of each ETC lane within the toll plaza. These settings include device communication addresses and operating modes. Multiple lane control hosts that have completed initial configuration are then connected to the same multicast group, thus establishing a multicast communication network. After initial configuration, a device linkage test is performed to check whether each device can respond and exchange data normally. If any problems are found, automatic prompts for adjustments are provided.

[0035] Optionally, detecting a vehicle entering the lane license plate recognition area includes:

[0036] When a vehicle is detected entering the transaction area of ​​the antenna device, a dedicated short-range communication protocol is established between the antenna device and the vehicle's on-board unit to collect the vehicle's ETC transaction data. The lane control host encapsulates the ETC transaction data into multicast data frames and pushes the multicast data frames to the multicast group so that other lane control hosts that have joined the multicast group can receive and store the ETC transaction data.

[0037] The transaction area can be understood as the area covered by the antenna equipment's signal, where it can interact with the vehicle's on-board unit (O2O) for transactions. The O2O unit can be understood as an electronic device installed in the vehicle that can communicate with the antenna equipment and complete ETC transactions. The dedicated short-range communication protocol can be understood as the rules and conventions specifically designed for short-range communication between the roadside unit of the antenna equipment and the O2O unit.

[0038] A multicast data frame can be understood as a data unit that encapsulates ETC transaction data in a specific format for multicast transmission.

[0039] Specifically, when a vehicle is detected entering a lane within the coverage area of ​​the antenna device, which allows for transaction interaction with the vehicle's onboard unit, the antenna device communicates with the onboard unit via a dedicated short-range communication protocol to collect the vehicle's ETC transaction data. The lane control host then encapsulates the ETC transaction data into a multicast data frame and pushes it to the multicast group, enabling other lane control hosts in the group to receive and store the ETC transaction data. This achieves cross-lane sharing of transaction data. During the data push process, the transmission status is monitored in real time; if a transmission failure occurs, it is automatically re-pushed to ensure successful data transmission to other devices within the group.

[0040] Optionally, the collected ETC transaction data of the vehicle includes:

[0041] Collect vehicle-mounted unit (V2U) associated data and transaction control data, and determine the ETC transaction data based on the V2U associated data and the transaction control data.

[0042] Among them, on-board unit associated data can be understood as various information data associated with the on-board unit. Transaction control data can be understood as relevant data used to control the ETC transaction process.

[0043] Specifically, the system collects related data on the vehicle-mounted unit and transaction control data used to control the transaction process. The system combines the related data on the vehicle-mounted unit and the transaction control data to determine the final ETC transaction data, ensuring the integrity and accuracy of the ETC transaction data.

[0044] Optionally, the vehicle unit associated data includes the vehicle unit serial number, the transaction license plate identifier bound to the vehicle unit, and the transaction account identifier to which the vehicle unit is bound. The transaction control data includes preset toll rules, lane number, and system timestamp.

[0045] Among these, the vehicle unit serial number can be understood as a unique identifier for the vehicle unit. The transaction license plate identifier can be understood as information identifying the license plate corresponding to the transaction. The associated transaction account identifier can be understood as identifying the transaction account linked to the vehicle unit. The preset toll rules can be understood as pre-set rules for calculating tolls based on vehicle type, mileage, etc. The lane number can be understood as a number used to distinguish different lanes. The system timestamp can be understood as information recorded by the system that marks the time the data was generated.

[0046] S120. The lane control host filters out candidate transaction data that matches the time sequence of the license plate recognition data from the locally stored ETC transaction data, matches the transaction license plate in the candidate transaction data with the recognized license plate, and sends a release or interception command to the lane barrier machine according to the matching result.

[0047] ETC transaction data can be understood as transaction-related data generated when a vehicle passes through the ETC system, such as the license plate number, transaction time, and toll information. Time-series matching can be understood as the process of filtering data with a reasonable temporal correlation based on the order in which the data was generated. Candidate transaction data can be understood as transaction data that may correspond to the current license plate recognition data, filtered from the stored ETC transaction data. The license plate number being traded can be understood as the license plate information bound to the vehicle's on-board unit in the ETC system. License plate recognition can be understood as the vehicle's license plate information actually recognized by the license plate recognition device. The lane barrier can be understood as a device installed on the lane that, upon command, raises the barrier to allow passage or lowers it to block passage. A passage command can be understood as an instruction to raise the barrier to allow the vehicle to pass. An interception command can be understood as an instruction to lower the barrier to prevent the vehicle from passing.

[0048] Specifically, the lane control host filters candidate transaction data from all locally stored ETC transaction data based on time relationships, selecting those that match the recently received license plate recognition data. It then compares the license plates recorded in the candidate transaction data with the recognized license plates, and issues a release or interception command to the lane barrier based on the comparison result. If data anomalies are detected during the matching process, such as the absence of candidate transaction data, the system can automatically trigger an alarm, alerting staff to intervene.

[0049] S130: When the lane control host sends the release command, it generates release notification data and encapsulates it into a release notification multicast frame. The release notification data can be understood as data recording information related to the vehicle being released, used to notify other devices.

[0050] Among them, the release notification multicast frame can be understood as a data unit used for multicast transmission after the release notification data is encapsulated in a specific format.

[0051] Specifically, after the lane control host issues a release command, it generates relevant information recording that the vehicle has been released, such as vehicle information and release time, as release notification data. This data is then encapsulated into a release notification multicast frame according to a prescribed format. During the encapsulation process, the data is encrypted to prevent tampering or leakage during transmission.

[0052] Optionally, after encapsulation into a release notification multicast frame, it also includes:

[0053] The release notification multicast frame is pushed to the multicast group through the multicast network, so that other lane control hosts that have joined the multicast group can clear the corresponding ETC transaction data stored locally according to the notification multicast frame.

[0054] Specifically, after encapsulating the data into a release notification multicast frame, the frame is pushed to the multicast group via the multicast network. This allows other lane control hosts in the multicast group to clear the corresponding ETC transaction data stored locally based on the information in the notification multicast frame. This avoids useless data occupying storage resources and prevents subsequent vehicles from mistakenly matching these processed transaction data.

[0055] Preferably, log records are generated based on the cleanup operation, including cleanup transaction data information, cleanup time, etc., to facilitate subsequent system auditing and problem tracing.

[0056] Optionally, the method further includes:

[0057] When adjacent lane interference is detected, causing the vehicle to conduct ETC transactions at the antenna device in a lane other than the current driving lane, the ETC transaction data of the vehicle is synchronized to all lane control hosts in the multicast group through the multicast network via the control host of the lane other than the current driving lane.

[0058] The control host of the current driving lane filters out the transaction data that matches the license plate recognition data of the vehicle from the multicast synchronized ETC transaction data, and sends a release instruction to the lane barrier machine based on the matching result.

[0059] Adjacent lane interference can be understood as the mutual influence of equipment signals in adjacent lanes, causing vehicles to transact in lanes other than their current driving lane. A lane other than the current driving lane can be understood as a lane that a vehicle has not actually entered, but whose onboard unit is activated for transacting due to interference. The current driving lane can be understood as the lane that the vehicle has actually entered.

[0060] Specifically, when an ETC transaction is detected on an antenna device in a lane other than the vehicle's current lane due to adjacent lane interference, the control host of the non-current lane will synchronize the vehicle's ETC transaction data to all lane control hosts in the multicast group via a multicast network. The control host of the current lane will then filter the ETC transaction data synchronized via multicast to find the transaction data that matches the vehicle's license plate recognition association data, and send a release command to the lane barrier based on the matching result. This solves the problem of transaction and lane mismatch caused by adjacent lane interference, ensuring that vehicles can pass normally.

[0061] Preferably, when filtering and matching data, in addition to time and license plate, auxiliary information such as vehicle driving trajectory is also combined to further improve the accuracy of matching.

[0062] The technical solution of this invention addresses technical problems such as transaction and lane mismatch and vehicle misinterpretation caused by adjacent lane interference by generating release notification data and encapsulating it into a release notification multicast frame when a vehicle enters the lane license plate recognition area. This achieves the technical effects of improving ETC passage efficiency and reducing misjudgments due to adjacent lane interference.

[0063] Figure 2 This is a scenario diagram illustrating the multicast-shared ETC transaction method implemented in this embodiment of the invention. For example... Figure 2As shown, in this scenario, the normal ETC transaction process is as follows:

[0064] 1) When the current vehicle passes through lane 1, it enters the antenna transaction area, and the antenna in lane 1 triggers the current vehicle's tag and initiates an ETC transaction.

[0065] 2) The vehicle continues to move forward into the license plate recognition area of ​​lane 1, and the license plate recognition device identifies the license plate of the vehicle.

[0066] 3) The license plate recognition result of lane 1 is matched with the license plate of the vehicle in the antenna transaction, and the current vehicle is set to be allowed to pass.

[0067] The ETC transaction process under conditions of preventing interference from adjacent roads is as follows:

[0068] 1) When the current vehicle passes through lane 1 and enters the antenna trading area, adjacent lane interference occurs, the antenna in lane 2 activates the tag, and a transaction occurs;

[0069] 2) Lane 2 synchronizes transaction information to Lane 1 via multicast;

[0070] 3) The vehicle continues to move forward and enters the license plate recognition area of ​​lane 1. The license plate recognition device identifies the license plate of the vehicle.

[0071] 4) Lane 1 matches the transaction information of the current vehicle from the multicast information, and then allows the current vehicle to pass;

[0072] 5) After allowing the current vehicle to pass through lane 1, notify lane 2 again via multicast to clear the transaction information of the current vehicle.

[0073] The technical solution of this invention enables cross-lane sharing of ETC transaction data, license plate matching, and synchronous clearing of transaction information for vehicles in both normal traffic and adjacent lane interference scenarios through a multicast network. This achieves efficient release of vehicles with normal transactions and accurate identification and release of vehicles interfering with adjacent lane interference, thereby improving the efficiency of ETC lane passage, eliminating the problem of mis-release and mis-blocking caused by adjacent lane interference, and ensuring toll collection order.

[0074] Figure 3 This is a schematic diagram of the structure of an ETC trading device based on multicast sharing, provided as an embodiment of the present invention. Figure 3 As shown, the device includes: a license plate recognition module 310, an instruction sending module 320, and a release notification module 330.

[0075] The license plate recognition module 310 is used to collect license plate recognition associated data of the vehicle through the license plate recognition device when a vehicle is detected entering the lane license plate recognition area, and send the license plate recognition associated data to the lane control host; the instruction sending module 320 is used by the lane control host to filter out candidate transaction data that matches the time sequence of the license plate recognition data from the locally stored ETC transaction data, match the transaction license plate in the candidate transaction data with the recognized license plate, and send a release or interception instruction to the lane barrier machine according to the matching result; the release notification module 330 is used to generate release notification data and encapsulate it into a release notification multicast frame when the lane control host sends the release instruction.

[0076] The technical solution of this invention addresses technical problems such as transaction and lane mismatch and vehicle misinterpretation caused by adjacent lane interference by generating release notification data and encapsulating it into a release notification multicast frame when a vehicle enters the lane license plate recognition area. This achieves the technical effects of improving ETC passage efficiency and reducing misjudgments due to adjacent lane interference.

[0082] In some optional embodiments, the license plate recognition module is specifically used for:

[0083] Collect vehicle-mounted unit (V2U) associated data and transaction control data, and determine the ETC transaction data based on the V2U associated data and the transaction control data.

[0084] In some optional embodiments, the vehicle unit associated data includes the vehicle unit serial number, the transaction license plate identifier bound to the vehicle unit, and the transaction account identifier to which the vehicle unit is bound. The transaction control data includes preset toll rules, lane number, and system timestamp.

[0085] In some alternative embodiments, the apparatus further includes:

[0086] The interference detection module is used to synchronize the vehicle's ETC transaction data to all lane control hosts in the multicast group via a multicast network when it detects that there is adjacent lane interference causing the vehicle to conduct ETC transactions on the antenna device in a lane other than the current driving lane.

[0087] The synchronization matching module is used to filter out transaction data that matches the license plate recognition data of the vehicle from the multicast synchronized ETC transaction data through the control host of the current driving lane, and send a release instruction to the lane barrier machine based on the matching result.

[0088] In some alternative embodiments, the apparatus further includes:

[0089] The data cleaning module is used to push the release notification multicast frame to the multicast group through the multicast network after it is encapsulated into a release notification multicast frame, so that other lane control hosts that have joined the multicast group can clean up the corresponding ETC transaction data stored locally according to the notification multicast frame.

The method of claim 2, wherein, The detection that a vehicle enters a lane license plate recognition area comprises the following steps: When a vehicle is detected to enter the transaction area of the antenna device, a dedicated short-range communication protocol interaction is established between the antenna device and the vehicle-mounted unit of the vehicle to collect ETC transaction data of the vehicle; The ETC transaction data is encapsulated into a multicast data frame by the lane control host, and the multicast data frame is pushed to the multicast group, so that other lane control hosts joined in the multicast group receive and store the ETC transaction data.

4. The method of claim 3, wherein, The collection of ETC transaction data of the vehicle comprises the following steps: The vehicle-mounted unit associated data and transaction control data are collected, and the ETC transaction data is determined based on the vehicle-mounted unit associated data and the transaction control data.

5. The method of claim 4, wherein, The vehicle-mounted unit associated data includes the vehicle-mounted unit serial number, the transaction license plate identification bound to the vehicle-mounted unit, and the transaction account identification to which the vehicle-mounted unit is bound. The transaction control data includes a preset tolling rule, a lane number and a system timestamp.

6. The method of claim 1, wherein, The application further comprises the following steps: When it is detected that there is adjacent lane interference causing the vehicle to have an ETC transaction at the antenna device of a non-current driving lane, the ETC transaction data of the vehicle is synchronized to all lane control hosts in the multicast group through the multicast network by the control host of the non-current driving lane; The control host of the current driving lane filters transaction data matching the license plate recognition associated data of the vehicle from the multicast synchronized ETC transaction data, and sends a release instruction to the lane barrier machine based on the matching result.

7. The method of claim 1, wherein, After being encapsulated into a release notification multicast frame, the application further comprises the following steps: The release notification multicast frame is pushed to the multicast group through the multicast network, so that other lane control hosts joined in the multicast group clean up the corresponding ETC transaction data stored locally according to the notification multicast frame.

8. An ETC transaction device based on multicast sharing, characterized by, The application comprises the following steps: A license plate recognition module is configured to collect license plate recognition associated data of a vehicle through a license plate recognition device when the vehicle enters a lane license plate recognition area, and send the license plate recognition associated data to a lane control host; The instruction sending module is configured to filter candidate transaction data matching the time sequence of the license plate recognition data from the locally stored ETC transaction data, match the transaction license plate in the candidate transaction data with the recognized license plate, and send a release or interception instruction to the lane barrier machine according to the matching result; The release notification module is configured to generate release notification data and encapsulate the release notification data into a release notification multicast frame when the lane control host sends the release instruction.
