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 working of an ETC antenna and the self-service payment device. Background Art

[0003] In recent years, with the in-depth development of the concept of "Internet +", the charging model of highway toll stations has been continuously innovated, and ETC payment and self-service payment have gradually become popular. In self-service payment equipment, the detection, reading, writing and recycling functions of CPC cards are key parts. The CPC card processing process of the current self-service payment equipment is as follows: the owner puts the CPC card into the delivery port, the device detects the card through a sensor or 13.56MHz card reading technology, and reports the card insertion information to the lane system. After receiving the instruction, the lane starts the 13.56MHz card reading and writing process, and reads and clears the CPC card through the card reader. If the reading and writing is successful, the device will control the CPC card to be recycled; if it fails, the lane will issue an alarm signal and require manual intervention.

[0004] At present, most self-service smart lanes are composite lanes that integrate ETC antennas and self-service payment machines. The ETC antenna is used to process the on-board unit, and the self-service payment machine processes the CPC card. Many CPC cards integrate 5.8GHz DSRC radio frequency functions and 13.56MHz card reading and writing functions. Usually, the 5.8GHz radio frequency function is enabled for communication at the entrance of the lane, and the radio frequency function is turned off for reading, writing and clearing cards at the exit of the lane. However, since many CPC cards use the 5.8GHz DSRC radio frequency priority communication mechanism, this will cause the 5.8GHz radio frequency signal to interfere with the 13.56MHz card reader of the self-service payment machine in the composite lane, affecting the reading of CPC cards.

[0005] However, under the interference of 5.8GHz DSRC radio frequency signal, 13.56MHz card reader cannot successfully read 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.

[0006] 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.

[0029] See also Figure 1 , Figure 1 A schematic flow chart of the collaborative working method of the ETC antenna and the self-service payment device provided in the embodiment of the present invention. The collaborative working method of 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 realize the smooth reading and writing of the CPC card and vehicle billing; first, the license plate information is obtained through the vehicle type recognition integrated machine, and the multiple information files of the CPC card are read through the ETC antenna to perform fuzzy matching of the license plate information to ensure that the billing is performed after the match is successful; secondly, the ETC antenna cooperates with the self-service payment machine. After the owner completes the payment, the CPC card information is ensured to be updated in time through the card clearing operation to avoid card reading failure; the whole process includes two-way information exchange between the ETC antenna and the self-service payment machine, and the fuzzy matching method is used to improve the reading success rate and reduce the occurrence of special situations. Through this mechanism, it is ensured that the ETC antenna and the self-service payment machine work together to complete vehicle billing and CPC card management efficiently and safely.

[0030] Figure 1 FIG. 1 is a flow chart of a method for cooperating between an ETC antenna and a self-service payment device provided by an embodiment of the present invention. Figure 1 As shown, the method includes the following steps S110 to S180.

[0031] S110, obtaining vehicle license plate information collected from the vehicle type recognition integrated machine.

[0032] In this embodiment, when a vehicle enters the composite exit lane, the vehicle type recognition integrated machine installed on the lane automatically captures and analyzes the vehicle image. The device uses advanced image processing technology and pattern recognition algorithms to accurately identify the type of vehicle and the license plate number. Once the recognition is completed, the vehicle type recognition integrated machine transmits the obtained license plate information to the lane software (i.e., the industrial computer) for subsequent matching and verification processes. This step ensures that the system can quickly and accurately identify each vehicle entering and exiting the lane, providing basic data support for automated toll collection.

[0033] S120, obtaining 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 will search for the CPC card, and the oncoming vehicle CPC will wake up the ETC antenna and return the wake-up information so that the ETC antenna and the CPC can establish a link.

[0034] In this embodiment, the information files include 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.

[0035] The information file is encapsulated into a CPC information data frame by the ETC antenna and sent to the industrial computer.

[0036] Specifically, in S120, the ETC antenna (RSU) establishes a wireless communication link with the CPC card carried by the vehicle. This step is achieved by the ETC antenna sending a signal of a specific frequency and performing a handshake protocol with the receiving system inside the CPC card. After the connection is successfully established, both parties can start secure data exchange.

[0037] Once a reliable communication channel is established, the ETC antenna will read a series of predefined information files from the CPC card. These files are essential for determining the vehicle's travel path and calculating the tolls payable. Specifically, they include but are not limited to the following files: System information file: Contains configuration parameters about the entire ETC system.

[0038] CPC card basic information file: records the basic properties and status of the card.

[0039] Entrance and exit information file: records the specific location and time when a vehicle enters the expressway network.

[0040] Route information file: describes the vehicle's driving trajectory throughout the network.

[0041] Billing information file: saves the expected charging amount calculated based on the path information.

[0042] After all the above information files are collected by the ETC antenna, they will be encapsulated into a standardized data structure - "CPC information data frame". This data frame not only contains the content of the original information file, but may also be attached with some additional metadata, such as timestamps or checksums, to ensure data integrity and security. Subsequently, the data frame is sent to the industrial computer (i.e., lane software) responsible for processing logical operations and decision-making through the appropriate interface protocol.

[0043] Through these two steps, the system can effectively obtain relevant information about the vehicle and prepare for the next step of license plate comparison, billing processing, etc. This process reflects the characteristics of the combination of information technology and physical facilities in modern intelligent transportation systems, aiming to improve road traffic efficiency and service quality.

[0044] S130: Perform fuzzy matching on the information file and the vehicle license plate information to obtain a matching result.

[0045] 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.

[0046] Specifically, fuzzy matching aims to solve data inconsistency problems that may be encountered in practical applications, such as differences in license plate information due to image recognition errors, signal interference, or card data corruption. By adopting fuzzy matching technology, the system can increase the tolerance of license plate recognition results and thus more accurately determine the identity of the vehicle.

[0047] First, clean up the license plate image recognition results from the vehicle identification machine and the license plate information in the CPC card, remove any unnecessary characters, and convert all data into a unified format, such as converting all to uppercase or lowercase letters. If the license plate information contains area codes or other non-alphanumeric characters, it may be necessary to segment it and only keep the core part for matching. At the same time, extract the key features of the license plate information, such as color, style and other auxiliary information (if any).

[0048] Use a specially designed algorithm to calculate the similarity between two license plate information. This can be based on the Levenshtein distance, Jaro-Winkler distance, or other methods suitable for text comparison. Set a reasonable similarity threshold. When the similarity between two license plate information exceeds this threshold, they are considered to belong to the same car; otherwise, they are considered to be different cars. The choice of threshold should take into account the specific needs of the actual application scenario, including but not limited to factors such as traffic speed and safety requirements.

[0049] If the license plate information is highly consistent or the similarity exceeds the set threshold, the system will determine that the CPC card carried by the current vehicle matches its actual license plate. At this time, the lane software will continue to perform the next step, such as billing processing. On the contrary, if the license plate information is very different and fails to meet the set similarity standard, the system will consider that there is an abnormality. At this time, it will usually choose to release the link between the ETC antenna and the CPC card, stop further automatic processing, and may prompt staff to intervene for inspection.

[0050] Once the matching result is obtained, the system will take corresponding actions based on the result. For vehicles that are successfully matched, the system will continue to perform subsequent processing according to the predetermined business logic, such as billing, card clearing, etc.; for unmatched vehicles, the system will trigger the safety mechanism to prevent the occurrence of wrong charges or illegal behavior.

[0051] 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 safety of the highway toll collection system.

[0052] S140. 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 a card clearing operation.

[0053] In this embodiment, the CPC card is billed, 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.

[0054] Specifically, based on the specific conditions 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.

[0055] 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.

[0056] 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.

[0057] This card clearing instruction is sent to the ETC antenna through the communication interface, instructing it to start the update operation of the CPC card.

[0058] After the ETC antenna receives the card clearing instruction, it will first write the relevant information of the current exit into the "entry and exit information file" in 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.

[0059] Next, the ETC antenna clears the "path information file" and "billing information file" in the CPC card. These files store detailed records of the vehicle's path throughout the journey and the details of the fees incurred along the way. Clearing this information is to ensure that the card can be reused for other vehicles.

[0060] After completing all the above operations, the ETC antenna will disconnect the communication connection with the CPC card. This is to prevent confusion when subsequent vehicles pass through the same toll station again, and also to ensure the security and independence of each transaction process.

[0061] After the ETC antenna completes its task, it will return a status report to the lane software to confirm that all operations have been executed correctly. If any problems are encountered during the process, error information will also be reported at this stage for timely processing. Whether it is a successful transaction or an abnormal situation, the system will record the relevant events in detail and form a log file. This is crucial for subsequent audits, troubleshooting, and other work.

[0062] 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.

[0063] S150, after the car owner inserts the CPC card into the self-service payment machine, determining whether the CPC card is successfully cleared; 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.

[0064] In this embodiment, the billing information is sent to the self-service payment machine, and a voice prompt is used to prompt payment.

[0065] For CPC cards that have been processed by the ETC antenna, the self-service payment machine only recycles the CPC cards.

[0066] S170: If the CPC card clearing is unsuccessful, obtain the information in the CPC card read by the 13.56 MHz card reader of the self-service payment machine.

[0067] 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.

[0068] Specifically, when the ETC antenna is performing a card clearing operation, the card clearing operation fails due to network congestion and other issues, and the payment is not completed this time. In this case, the self-service payment machine needs to coordinate the processing. First, the 13.56MHz card reader of the self-service payment machine activates the CPC card, and after the CPC card returns the activation information, the car owner puts 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 that a card has entered and triggers the 13.56MHz card reader to start working.

[0069] 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.

[0070] 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.

[0071] The entry and exit information file records data such as the timestamp, entry number, and exit number of the vehicle entering and exiting the highway. This information is crucial for verifying the vehicle's travel path.

[0072] The route information file records in detail all the 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.

[0073] The billing information file includes the total cost calculated based on the routing information, as well as any applicable discount or surcharge information, ensuring accurate billing.

[0074] After receiving all the above information, the self-service payment machine will parse it to extract the necessary field values. By comparing the time and location records in the entry and exit information files and other relevant information, it will check whether there are any abnormalities, such as long-term detention or illegal routes. Based on the contents of the route information file and the billing information file, the amount payable will be calculated again and displayed to the car owner for confirmation.

[0075] The self-service payment machine provides clear screen prompts or voice guidance to the car owner, telling them what to do next, such as choosing a payment method (cash, credit card, mobile payment, etc.). Once the car owner completes the payment, the self-service payment machine will update the CPC card status and may also print a receipt as proof of the transaction.

[0076] After the transaction is completed, the self-service payment machine will eject the CPC card or allow the owner to take it out so that he can continue to use it or return it to the relevant agency. As with the previous steps, the entire card reading and payment process will be recorded in detail to form a log file for future query and audit.

[0077] 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.

[0078] 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, sending a card clearing instruction to the self-service payment machine so that the self-service payment machine performs a card clearing operation, and executing step S160.

[0079] 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, and the self-service payment machine writes the exit information into the entry and exit information file, and clears the path information file and the billing information file.

[0080] In this embodiment, the fuzzy matching is consistent with the above-mentioned step S130, which will not be described in detail here.

[0081] In addition, when the matching result is that the license plate is inconsistent, the ETC antenna releases the communication link with the CPC card.

[0082] Specifically, the industrial computer calculates the vehicle's payable fees based on the information in the CPC card read in the previous steps (including but not limited to the system information file, CPC card basic information file, entrance and exit information file, path information file, and billing information file). Subsequently, the industrial computer generates a data frame containing this billing information - "CPC information data frame", and sends this data frame to the self-service payment machine through a secure and reliable communication link.

[0083] After receiving the CPC information data frame, the self-service payment machine will parse and verify the information in it to ensure data integrity and accuracy. This step is to prevent inaccurate billing due to data transmission errors or abnormal situations.

[0084] 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.

[0085] To further improve the user experience, the self-service payment machine will also use voice announcements to remind car owners to pay. For example, it may play a voice prompt like "Your toll is XX yuan, please scan the code to complete the payment." This multi-modal interaction design (visual + auditory) can effectively guide car owners to complete subsequent operations, especially for those who may not notice the screen display or have reading difficulties.

[0086] In addition to directly informing the fees, the voice prompts 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.

[0087] After hearing the voice prompt, the car owner can take corresponding actions according to the instructions, such as taking out the mobile phone to scan the QR code displayed on the screen to complete the online payment. When the car owner completes the payment according to the instructions, the self-service payment machine will feedback the payment success message to the lane software, and the lane software will update the status accordingly, and may issue an instruction to recycle the CPC card to end the entire payment process.

[0088] In summary, in this embodiment, by sending the billing information to the self-service payment machine and combining it with voice prompts, not only the efficiency and accuracy of information transmission are improved, but also the friendliness of human-computer interaction is enhanced, thereby ensuring that the car owner can complete the payment process smoothly and efficiently. This process reflects the intelligent and service-oriented design concept of the modern traffic management system.

[0089] In this embodiment, the reading and writing of CPC cards and vehicle billing are realized by combining DSRC radio frequency and 13.56MHz radio frequency technology. The system effectively solves the problem that CPC cards cannot be read due to ETC antenna interference in existing payment equipment, thereby avoiding lane logic anomalies and providing support for special case processing. This method makes full use of the existing equipment of smart lanes, avoids additional equipment investment, and solves the card reading problem in the lane. If this technical solution is commercialized and industrialized, it will greatly improve a series of problems in the 13.56MHz radio frequency reading of CPC cards by self-service payment equipment, and provide an effective solution for the maintenance and management of the equipment.

[0090] 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 the 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 owner puts the CPC card into the self-service payment machine, the CPC card is recycled after payment when the CPC card is successfully cleared, and when the CPC card is not successfully cleared, the card information is read 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 owner to pay; finally, after the 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.
