Description

Technical Field

[0001] The present invention relates to a self-service payment device, and more specifically to a method and system for the coordinated operation of an ETC antenna and the self-service payment device. Background Art

[0002] In recent years, with the deepening development of the "Internet Plus" concept, toll collection models at highway toll booths have continued to innovate, with ETC and self-service payment methods becoming increasingly popular. CPC card detection, reading, writing, and recycling functions are key components of self-service payment devices. The current CPC card processing process for self-service payment devices is as follows: the driver inserts the CPC card into the insertion port. The device detects the card using a sensor or 13.56MHz card reader technology and reports the card insertion information to the lane system. Upon receiving the command, the lane system initiates the 13.56MHz card reading and writing process, reading and clearing the CPC card through the card reader. If the reading and writing is successful, the device controls the CPC card recycling; if it fails, the lane system issues an alarm, requiring manual intervention.

[0003] Currently, most self-service smart lanes are hybrid lanes, integrating ETC antennas and self-service payment machines. The ETC antenna processes the onboard unit, while the self-service payment machine processes CPC cards. Many CPC cards integrate both 5.8GHz DSRC radio frequency capabilities and 13.56MHz card reader / writer functions. Typically, the 5.8GHz radio frequency function is enabled for communication at lane entrances and disabled for reading, writing, and card clearing at lane exits. However, because many CPC cards prioritize 5.8GHz DSRC radio frequency communication, this can cause 5.8GHz radio frequency signals to interfere with the 13.56MHz card readers of self-service payment machines in hybrid lanes, affecting CPC card reading.

[0004] However, due to interference from the 5.8GHz DSRC radio frequency signal, the 13.56MHz card reader cannot successfully read the CPC card. If the owner does not place the card correctly or the card is not aligned with the 13.56MHz card reader antenna area, the device will not be able to detect or read the card.

[0005] Therefore, it is necessary to design a new method to realize the collaborative working mechanism of the existing ETC antenna and self-service payment machine in the composite lane, effectively realize the reading and writing of CPC cards and vehicle billing, ensure the success rate of CPC card reading, and reduce the handling of special situations caused by card reading failure. Summary of the Invention

[0006] The purpose of the present invention is to overcome the defects of the prior art and provide a method and system for the coordinated working of an ETC antenna and a self-service payment device.

[0021] A further technical solution thereof is: after fuzzy matching is performed on the information file and the vehicle license plate information to obtain a matching result, the method further comprises:

When the CPC card is in the entry state and the license plate matches, a card clearing instruction is sent to the self-service payment machine, which writes the exit information into the entry and exit information file and clears the path information file and the billing information file.

[0026] A further technical solution is that the sending of billing information to the self-service payment machine and prompting for payment includes:

[0042] See also Figure 1 , Figure 1A schematic flow chart of the collaborative working method between the ETC antenna and the self-service payment device provided in an embodiment of the present invention. This collaborative working method between the ETC antenna and the self-service payment device is applied to an industrial computer. Specifically, the ETC antenna and the self-service payment device work together to achieve smooth reading and writing of CPC cards and vehicle billing. First, the vehicle model identification integrated device obtains license plate information, and the ETC antenna reads multiple information files of the CPC card, performs fuzzy matching on the license plate information, and ensures that billing is performed after a successful match. Second, the ETC antenna cooperates with the self-service payment machine. After the vehicle owner completes the payment, the card clearing operation ensures that the CPC card information is updated in a timely manner to avoid card reading failures. The entire process includes two-way information exchange between the ETC antenna and the self-service payment machine, and uses fuzzy matching methods to improve the reading success rate and reduce the occurrence of special circumstances. Through this mechanism, the ETC antenna and the self-service payment machine are ensured to work together, completing vehicle billing and CPC card management efficiently and safely.

[0043] Figure 1 This is a flow chart of the collaborative working method of the ETC antenna and the self-service payment device provided by the embodiment of the present invention. Figure 1 As shown, the method includes the following steps S110 to S180.

[0044] S110: Acquire vehicle license plate information collected from the vehicle type recognition integrated machine.

[0045] In this embodiment, when a vehicle enters a composite exit lane, a vehicle type recognition system installed in the lane automatically captures and analyzes the vehicle image. This device uses advanced image processing technology and pattern recognition algorithms to accurately identify the vehicle type and license plate number. Once identification is complete, the vehicle type recognition system transmits the acquired license plate information to the lane software (i.e., an industrial computer) for subsequent matching and verification. This step ensures that the system can quickly and accurately identify every vehicle entering and exiting the lane, providing the fundamental data support for automated toll collection.

[0046] S120: Acquire multiple information files of the CPC card read by the ETC antenna, wherein the ETC antenna establishes a communication link with the CPC card. In addition, before establishing the communication link, the ETC antenna searches for the CPC card. The oncoming CPC wakes up the ETC antenna and returns a wake-up message, thereby establishing a link between the ETC antenna and the CPC card.

[0047] In this embodiment, the information files include a system information file, a CPC card basic information file, a portal information file, a path information file, and a billing information file.

[0048] The information file is encapsulated into a CPC information data frame by the ETC antenna and sent to the industrial computer.

[0049] Specifically, in S120 , the ETC antenna (RSU) establishes a wireless communication link with the CPC card carried by the vehicle. This is achieved by the ETC antenna emitting a signal at a specific frequency and performing a handshake protocol with the receiving system within the CPC card. Once the connection is successfully established, both parties can begin secure data exchange.

[0050] Once a reliable communication channel is established, the ETC antenna reads a series of predefined information files from the CPC card. These files are crucial for determining the vehicle's route and calculating the toll. Specifically, they include but are not limited to the following:

[0051] System information file: Contains configuration parameters about the entire ETC system.

[0052] CPC card basic information file: records the basic attributes and status of the card.

[0053] Entrance and exit information file: records the specific location and time when a vehicle enters the expressway network.

[0054] Route information file: describes the vehicle's driving trajectory in the entire network.

[0055] Billing information file: stores the expected charge amount calculated based on the route information.

[0056] After being collected by the ETC antenna, all of these information files are encapsulated into a standardized data structure called a CPC information frame. This frame not only contains the original information file content but may also include additional metadata, such as a timestamp or checksum, to ensure data integrity and security. This frame is then sent via the appropriate interface protocol to an industrial computer (i.e., lane software) responsible for processing logical operations and decision-making.

[0057] Through these two steps, the system can effectively obtain relevant vehicle information and prepare for the next steps, such as license plate comparison and billing. This process embodies the integration of information technology and physical infrastructure in modern intelligent transportation systems, aiming to improve road traffic efficiency and service quality.

[0058] S130: Perform fuzzy matching on the information file and the vehicle license plate information to obtain a matching result.

[0059] In this embodiment, the matching result refers to whether the license plate information in the information file is consistent with the vehicle license plate information.

[0060] Specifically, fuzzy matching aims to address data inconsistencies that may be encountered in real-world applications, such as discrepancies in license plate information due to image recognition errors, signal interference, or card data corruption. By employing fuzzy matching technology, the system can improve its tolerance for license plate recognition results, thereby more accurately determining vehicle identity.

[0061] First, clean the license plate image recognition results from the vehicle identification machine and the license plate information on the CPC card, removing any unnecessary characters and converting all data to a unified format, such as converting all letters to uppercase or lowercase. If the license plate information contains area codes or other non-alphanumeric characters, it may be necessary to segment it, retaining only the core portion for matching. At the same time, extract key features of the license plate information, such as color, style, and other auxiliary information (if any).

[0062] Use a specially designed algorithm to calculate the similarity between two license plates. This can be based on Levenshtein distance, Jaro-Winkler distance, or other methods suitable for text comparison. Set a reasonable similarity threshold. When the similarity between two license plates exceeds this threshold, they are considered to belong to the same vehicle; otherwise, they are considered to belong to different vehicles. The choice of threshold should take into account the specific requirements of the actual application scenario, including but not limited to factors such as traffic speed and safety requirements.

[0063] If the license plate information matches closely or exceeds a set threshold, the system will determine that the CPC card carried by the vehicle matches the actual license plate. The lane software will then proceed to the next step, such as billing. Conversely, if the license plate information differs significantly and fails to meet the set similarity threshold, the system will deem an anomaly. In this case, the link between the ETC antenna and the CPC card will typically be released, halting further automated processing and potentially prompting staff for inspection.

[0064] Once a match is obtained, the system will take appropriate action based on the result. For successfully matched vehicles, the system will continue to follow the predetermined business logic for subsequent processing, such as billing and card clearing. For unmatched vehicles, however, a safety mechanism will be triggered to prevent incorrect charges or illegal activities.

[0065] In summary, step S130 ensures that only legal and correct vehicles can successfully complete the automated payment process through fuzzy matching of vehicle license plate information and information files in the CPC card, thereby ensuring the efficient operation and security of the highway toll collection system.

[0066] S140. When the matching result shows that the license plates are consistent, the CPC card is charged and a card clearing instruction is sent to the ETC antenna so that the ETC antenna performs a card clearing operation.

[0067] In this embodiment, the CPC card is charged, and a card clearing instruction is sent to the ETC antenna, so that the ETC antenna writes the exit information into the entry and exit information file, clears the path information file and the billing information file, and the ETC antenna releases the communication link with the CPC card.

[0068] Specifically, based on the specific circumstances of the road section through which the vehicle passes, including but not limited to factors such as driving distance, road section rate, and vehicle model, the lane software calculates the toll to be collected.

[0069] If the vehicle uses an ETC account or prepaid card, the system will directly deduct the corresponding amount from the corresponding account; if it is a postpaid mode, a bill will be generated and sent to the car owner.

[0070] The industrial computer constructs a data packet containing a card clearing command and encapsulates it into an information frame suitable for the ETC antenna transmission format.

[0071] This card clearing instruction is sent to the ETC antenna through the communication interface, instructing it to start updating the CPC card.

[0072] After receiving the clear card command, the ETC antenna first writes the relevant information of the current exit into the "entry and exit information file" on the CPC card. This usually includes data such as the exit number and timestamp, which is used to record the time and location of the vehicle leaving the highway.

[0073] Next, the ETC antenna clears the CPC card's "route information file" and "fare information file." These files store the vehicle's detailed route throughout the trip and the detailed tolls incurred along the way. This information is cleared to ensure the card can be reused for other vehicles.

[0074] After completing all the above operations, the ETC antenna will disconnect from the CPC card to prevent confusion when subsequent vehicles pass through the same toll booth again, while also ensuring the security and independence of each transaction process.

[0075] After completing its task, the ETC antenna returns a status report to the lane software, confirming that all operations were executed correctly. Any problems encountered during the process are also reported here for prompt resolution. Whether successful transactions or exceptions, the system records the relevant events in detail in a log file. This is crucial for subsequent audits and troubleshooting.

[0076] To sum up, in this embodiment, when the license plate information is consistent, the system will not only accurately bill the vehicle, but also safely and effectively update the status of the CPC card through the ETC antenna, ensuring the efficient operation and service quality of the entire highway electronic toll collection system.

[0077] S150: After the car owner inserts the CPC card into the self-service payment machine, it is determined whether the CPC card is successfully cleared;

[0078] S160: If the CPC card is cleared successfully, the billing information is sent to the self-service payment machine and the payment is prompted. After the car owner completes the payment, the CPC card is recovered in conjunction with the self-service payment machine.

[0079] In this embodiment, the billing information is sent to the self-service payment machine, and a voice prompt is used to prompt payment.

[0080] For CPC cards that have been processed by the ETC antenna, the self-service payment machine will only recycle the CPC cards.

[0081] S170: If the CPC card clearing is unsuccessful, obtain information from the CPC card read by the 13.56 MHz card reader of the self-service payment machine.

[0082] In this embodiment, the information includes a system information file, a CPC card basic information file, an entry and exit information file, a path information file, and a billing information file.

[0083] Specifically, if the ETC antenna fails to clear the card due to network congestion or other issues, and the payment is not completed, the self-service payment machine will need to coordinate the process. First, the self-service payment machine's 13.56MHz card reader activates the CPC card. After the CPC card returns the activation information, the driver inserts the CPC card into the slot or sensing area of ​​the self-service payment machine in the specified direction and position. The sensor inside the self-service payment machine recognizes the card and triggers the 13.56MHz card reader to start working.

[0084] The read content includes some basic information about the CPC card itself, such as card type, version number, etc., which helps to confirm whether the card supports the operation of the current self-service payment machine.

[0085] The CPC card basic information file contains fixed information such as the issuing agency code and card serial number, which is used to verify the authenticity and legality of the card.

[0086] The entry and exit information file records data such as the timestamp, entry number, and exit number of vehicles entering and exiting the highway. This information is crucial for verifying the vehicle's travel path.

[0087] The route information file records in detail all key nodes (such as toll booths, forks) passed by the vehicle during the entire journey, as well as any special road segment identifiers that may exist, which helps to accurately calculate the tolls payable.

[0088] The billing information file includes the total cost calculated based on the routing information, as well as any applicable discounts or surcharges, to ensure accurate billing.

[0089] After receiving all of this information, the self-service payment machine parses it to extract the necessary field values. By comparing the time and location records in the entry and exit information files with other relevant information, it checks for any anomalies, such as extended delays or illegal routes. Based on the contents of the route information files and the billing information files, the machine recalculates the amount due and displays it to the driver for confirmation.

[0090] The self-service payment machine provides clear on-screen or voice guidance to the driver, informing them of the next steps they need to take, such as selecting a payment method (cash, credit card, mobile payment, etc.). Once the driver completes the payment, the self-service payment machine updates the CPC card status and may also print a receipt as proof of transaction.

[0091] Once the transaction is complete, the self-service payment machine will eject the CPC card or allow the owner to remove it for further use or return it to the relevant agency. As with the previous steps, the entire card reading and payment process will be recorded in detail and generated into a log file for future reference and audit purposes.

[0092] In summary, in this embodiment, reading multiple types of information in the CPC card through the 13.56MHz card reader of the self-service payment machine can not only ensure the accuracy of billing, but also provide car owners with a convenient and efficient payment experience, while ensuring the security and reliability of the system.

[0093] S180, fuzzy matching the information with the vehicle license plate information. When the CPC card is in the entry state and the license plate matches, a card clearing instruction is sent to the self-service payment machine so that the self-service payment machine performs a card clearing operation and executes step S160.

[0094] In this embodiment, the information is fuzzy matched with the vehicle license plate information. When the CPC card is in the entry state and the license plate matches, a card clearing instruction is sent to the self-service payment machine, which writes the exit information into the entry and exit information file and clears the path information file and the billing information file.

[0095] In this embodiment, the fuzzy matching is consistent with the above-mentioned step S130 and will not be described in detail here.

[0096] In addition, when the matching result is that the license plates are inconsistent, the ETC antenna releases the communication link with the CPC card.

[0097] Specifically, the IPC calculates the vehicle's payable fare based on the information read from the CPC card in the previous steps (including but not limited to the system information file, CPC card basic information file, entrance and exit information file, route information file, and billing information file). The IPC then generates a data frame containing this billing information—a "CPC information data frame"—and sends this data frame to the self-service payment machine via a secure and reliable communication link.

[0098] After receiving the CPC information data frame, the self-service payment machine will parse and verify the information to ensure data integrity and accuracy. This step is to prevent inaccurate billing due to data transmission errors or abnormal situations.

[0099] Once the accuracy of the billing information is confirmed, the self-service payment machine will clearly display the specific billing details of the vehicle on its display screen, such as toll amount, travel time, starting and ending points, etc., so that the car owner can intuitively understand the fees he needs to pay.

[0100] To further enhance the user experience, self-service payment machines also use voice notifications to remind drivers to pay. For example, they might play a voice prompt like, "Your toll is XX yuan. Please scan the code to complete payment." This multimodal interaction design (visual and auditory) effectively guides drivers through subsequent operations, which is particularly important for users who may not pay attention to the screen display or have reading difficulties.

[0101] In addition to directly informing the fee, the voice prompt can also include simple instructions on how to pay using different payment methods, such as introducing the location of the QR code and how to scan it, or explaining other available payment options (such as cash, credit card, etc.) to help car owners quickly choose the most appropriate payment method.

[0102] After hearing the voice prompt, the driver can take appropriate action, such as taking out their phone to scan the QR code displayed on the screen to complete the online payment. Once the driver completes the payment as instructed, the self-service payment machine will report the payment success to the lane software, which will then update the status and may issue an instruction to retrieve the CPC card, completing the entire payment process.

[0103] In summary, this embodiment, by sending billing information to the self-service payment machine and combining it with voice prompts, not only improves the efficiency and accuracy of information transmission, but also enhances the user-friendly interaction between the user and the machine, thus ensuring that the driver can complete the payment process smoothly and efficiently. This process embodies the intelligent and service-oriented design concept of modern traffic management systems.

[0104] In this embodiment, CPC card reading and writing, as well as vehicle toll collection, are achieved by combining DSRC and 13.56MHz RF technologies. This system effectively addresses the issue of existing payment devices being unable to read CPC cards due to ETC antenna interference, thereby avoiding lane logic anomalies and providing support for handling special cases. This method fully utilizes existing smart lane equipment, avoiding additional equipment investment and resolving existing card reading issues within the lanes. If this technical solution is commercialized and industrialized, it will significantly improve a range of issues with CPC card 13.56MHz RF reading in self-service payment devices and provide an effective solution for equipment maintenance and management.

[0105] The above-mentioned collaborative working method of the ETC antenna and the self-service payment device improves the reading and writing success rate of the CPC card through the collaborative work of the ETC antenna and the self-service payment machine, combined with existing equipment; first, the ETC antenna establishes communication with the CPC card, reads the information in the card and performs fuzzy matching with the license plate information, ensuring that the vehicle and the card are matched before billing; if the car owner puts the CPC card into the self-service payment machine, the payment is made when the CPC card is successfully cleared and the CPC card is recycled. If the CPC card is not successfully cleared, the card information is read again through the 13.56MHz card reader and matched with the license plate to complete the card clearing operation; then, the system sends the billing information to the payment machine and prompts the car owner to pay; finally, after the car owner completes the payment, the CPC card is recycled by the self-service payment machine, ensuring the correct reading and writing of the card and the smooth operation of the lane, reducing the occurrence of abnormal situations.

[0106] Figure 2 This is a schematic block diagram of a collaborative working system of an ETC antenna and a self-service payment device provided by an embodiment of the present invention. Figure 2 As shown, corresponding to the above-mentioned method for cooperating between an ETC antenna and a self-service payment device, the present invention further provides a system for cooperating between an ETC antenna and a self-service payment device. The system for cooperating between an ETC antenna and a self-service payment device includes a unit for executing the above-mentioned method for cooperating between an ETC antenna and a self-service payment device, and the system can be configured in a server. Specifically, please refer to Figure 2 The ETC antenna and the self-service payment equipment collaborative working system include an industrial computer, RSU, self-service payment machine, vehicle type identification integrated machine and terminal. The RSU, self-service payment machine, vehicle type identification integrated machine and terminal are respectively connected to the industrial computer; wherein the industrial computer is used to:

[0107] Acquire vehicle license plate information collected from the vehicle type recognition integrated machine; acquire multiple information files of the CPC card read by the ETC antenna, wherein the ETC antenna establishes a communication link with the CPC card; perform fuzzy matching with the vehicle license plate information according to the information file to obtain a matching result; when the matching result is that the license plate is consistent, the CPC card is charged and a card clearing instruction is sent to the ETC antenna so that the ETC antenna performs the card clearing operation; when the car owner puts the CPC card into the self-service payment machine, it is determined whether the CPC card is successfully cleared; if the C If the PC card is cleared successfully, the self-service payment machine will recycle the CPC card that has been successfully cleared; if the CPC card is not cleared successfully, the information in the CPC card read by the 13.56MHz card reader of the self-service payment machine is obtained; the information is fuzzy matched with the vehicle license plate information. When the CPC card is in the entry state and the license plate matches, a card clearing instruction is sent to the self-service payment machine, so that the self-service payment machine performs the card clearing operation; the billing information is sent to the self-service payment machine, and the payment prompt is given; when the vehicle owner completes the payment, the CPC card is recycled in conjunction with the self-service payment machine.
