Description

Technical Field

[0001] The present invention relates to the field of intelligent transportation technology, and in particular to an ETC abnormal transaction processing system. Background Art

[0002] Since the abolition of provincial highway toll booths, the Electronic Toll Collection (ETC) system has been vigorously promoted. By the end of 2024, over 30,000 ETC gantries and 12,000 toll booths had been installed nationwide, including over 42,000 ETC lanes. The ETC payment utilization rate across the entire network has reached 65.73%. The ETC system uses 5.8GHz dedicated short-range communication technology between on-board units (OBUs) and roadside units (RSUs) to identify vehicles and automatically deduct tolls, significantly improving highway traffic efficiency and user experience. However, with the rapid growth in the number of ETC users, ETC lanes face new challenges in handling abnormal transactions.

[0003] The existing method for handling abnormal ETC lane transactions primarily relies on staff using handheld terminals to directly read information from the onboard unit (ORU) on the vehicle's windshield. This method addresses transaction failures to a certain extent, but it presents numerous practical challenges. Handheld terminals use the same 5.8GHz radio frequency signal as the RSU when handling abnormalities, which can easily lead to co-frequency signal interference and reduce processing effectiveness.

[0004] To avoid interference from co-frequency signals, existing technologies typically reduce interference by adjusting antenna angle, height, and beamwidth, and by installing isolation strips between adjacent lanes. However, these methods require high hardware and maintenance costs, and cannot completely eliminate interference, resulting in low success rates and efficiency in handling abnormal ETC transactions. Summary of the Invention

[0017] In some embodiments of the present invention, the system further comprises a barrier module; the barrier module is communicatively connected to the lane control module;

[0018] The lane control module is further configured to control the barrier module to lift and release the vehicle if the supplementary transaction message passes verification; or to send the verification result of the supplementary transaction message to the transaction terminal;

[0019] The transaction terminal is also used to output prompt information when receiving the inspection result; the prompt information is used to prompt the user to input the railing module control instruction, and the railing module control instruction is the instruction input by the user through the railing module control control or the image interface on the transaction terminal; when receiving the railing module control instruction, the transaction terminal controls the railing module to be raised or lowered according to the instructions of the railing module control instruction.

[0020] In some embodiments of the present invention, when the transaction terminal is a mobile handheld terminal, the transaction terminal includes a satellite positioning submodule;

[0021] The transaction terminal is also used to: obtain satellite positioning information through the satellite positioning submodule after moving to the lane where the vehicle is located; determine the lane marking of the lane based on the satellite positioning information; establish a communication channel with the lane control module based on the lane marking; and the lane marking and the lane control module have a one-to-one correspondence.

[0022] In some embodiments of the present invention, the transaction terminal pre-stores electronic fence information, including the shape, size, and geographic location coordinates of the electronic fence;

[0023] Determine lane markings based on satellite positioning information, including:

[0024] The transaction terminal compares the satellite positioning information with the electronic fence information to obtain a comparison result;

[0025] When the comparison result indicates that the transaction terminal is located within the electronic fence, the satellite positioning information is matched with the lane information on the preset lane map to determine the lane identification.

[0026] In some embodiments of the present invention, the communication channel between the lane control module and the transaction terminal is constructed based on a Bluetooth submodule; the lane control module further includes a Bluetooth submodule; the Bluetooth submodule is connected to the lane control module via a serial communication interface, and the module identifier of the Bluetooth submodule is the same as the lane identifier;

[0027] The transaction terminal is also used to obtain the Bluetooth submodule based on the lane identification query; establish a Bluetooth connection with the Bluetooth submodule to establish a communication channel between the transaction terminal and the lane control module.

[0028] In some embodiments of the present invention, after receiving the transaction abnormality information, the transaction terminal is also used to: output prompt information, the prompt information is used to prompt the user to enter the abnormal transaction processing instruction through the abnormal transaction processing control or graphic interface on the transaction terminal; when the abnormal transaction processing instruction is received, execute the step of obtaining satellite positioning information through the satellite positioning sub-module.

[0030] The ETC abnormal transaction processing system of the present invention has at least the following beneficial effects:

[0031] It can solve the problem of low success rate and efficiency in processing ETC abnormal transactions; by optimizing the system architecture and interactive process, when the lane control module detects a transaction abnormality, it will generate transaction abnormality information and send it to the transaction terminal; after receiving the abnormal information, the transaction terminal will generate an abnormal processing application instruction and send it to the lane control module; after receiving the application instruction, the lane control module will turn off the radio frequency signal of the roadside unit to avoid interference from the same frequency signal; then, the transaction terminal will establish a communication channel with the vehicle's on-board unit by broadcasting the radio frequency signal, obtain vehicle information and on-board unit information, and complete supplementary operations. While reducing manual intervention and improving processing efficiency, it also effectively solves the problem of same-frequency signal interference by turning off the radio frequency signal, which can significantly improve the success rate and efficiency of abnormal transaction processing in the ETC lane.

[0032] In addition, the lane entry coil module monitors the entry of vehicles into the lane, and combined with the logic of the lane control module, it determines whether there are other transaction vehicles, thereby optimizing the exception handling process; it can avoid the confusion caused by multiple vehicles handling exceptions at the same time and improve processing efficiency; at the same time, it can reduce system instability caused by vehicles waiting in queues, shorten the waiting time of vehicles in the lane, and improve user satisfaction.

[0033] In addition, after the supplementary transaction is completed, the abnormal transaction message is queried through fuzzy matching, the supplementary transaction message and the abnormal transaction message are merged to obtain a complete transaction message and upload it. This can ensure the integrity of the transaction data, facilitate subsequent audits and analysis, reduce manual intervention, improve processing efficiency, and reduce operating costs.

[0034] In addition, the transaction terminal is a mobile handheld terminal.

The staff can use the same transaction terminal to handle abnormal transactions in different lanes without changing the transaction terminal, further improving the efficiency of handling abnormal transactions; at the same time, it improves the adaptability to complex traffic environments.

[0035] In addition, by using satellite positioning information and electronic fence information to determine lane markings, the possibility of misoperation can be reduced and the accuracy of the system can be improved.

[0036] Additional advantages, objects, and features of the present invention will be set forth in part in the following description and will become apparent to those skilled in the art upon examination of the following or may be learned from practice of the present invention.

[0042] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0045] It should also be noted that, unless otherwise specified, the term "connection" herein may refer not only to a direct connection but also to an indirect connection involving an intermediate.

[0046] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the accompanying drawings, the same reference numerals represent the same or similar components, or the same or similar steps.

[0047] Figure 1 This is a schematic diagram of the structure of the ETC abnormal transaction processing system provided by an embodiment of the present application. Figure 1 As shown, the system at least includes: a road side unit (RSU) 110, a lane control module 120 and a transaction terminal 130.

[0048] Among them, the lane control module 120 establishes communication connections with the roadside unit 110 and the transaction terminal 130 respectively, including wired connections or wireless connections. This embodiment does not limit the communication method between the lane control module 120 and the roadside unit 110 and the transaction terminal 130.

[0049] The RSU 110 is a roadside device consisting of an antenna module and a radio frequency controller. The antenna module is responsible for transmitting / receiving, modulating / demodulating, encoding / decoding, and encrypting / decrypting signals and data, while the radio frequency controller controls data transmission and reception and processes information for upper-level computers.

[0050] The roadside unit 110 communicates with the onboard unit (OBU) of vehicles entering the transaction area by transmitting radio frequency signals. Based on this communication, it identifies the vehicle and conducts the ETC transaction. The roadside unit 110 then transmits the transaction data to the lane control module 120 via a communication connection with the lane control module 120. The transaction data includes information such as vehicle information and transaction amount.

[0051] In some embodiments of the present invention, the communication connection between the roadside unit 110 and the lane control module 120 is achieved through the Transmission Control Protocol / Internet Protocol (TCP / IP).

[0052] Specifically, the roadside unit 110 is used to conduct ETC transactions with vehicles in the transaction area through radio frequency signals to obtain transaction data; and send the transaction data to the corresponding lane control module 120.

[0053] During the ETC transaction process, signal interference, equipment failure, environmental factors, or communication problems between the vehicle-mounted unit and the roadside unit 120 may cause ETC transaction anomalies between the roadside unit 110 and the vehicle-mounted unit. Based on this, the roadside unit 110 needs to send transaction data to the lane control module 120.

[0054] When the lane control module 120 successfully receives the transaction data, it analyzes the transaction data and determines that the transaction is normal if the transaction data conforms to the preset transaction rules; otherwise, it determines that the transaction is abnormal.

[0055] Transaction data analysis includes data integrity checks to ensure that there are no data losses or errors. For example, the transaction data packet format, length, checksum, etc. are checked to ensure they are correct, and necessary data (such as license plate snapshots) is checked to ensure they are not missing.

[0056] In actual implementation, transaction data may also include transaction feedback information, which is used to indicate whether the transaction is normal or abnormal.

[0057] Among them, the transaction feedback information can be the information that the on-board unit feeds back to the roadside unit after the transaction is completed. After receiving the transaction feedback information, the roadside unit 110 adds the transaction feedback information to the transaction data and sends it to the lane control module 120; or, the transaction feedback information can also be the status information sent by the roadside unit 110 to the lane control module 120 based on its own communication status and transaction processing status. If communication failure, signal interference or other problems occur during the transaction process, the transaction abnormality is reported to the lane control module 120 through the transaction feedback information.

[0058] If the transaction data received by the lane control module 120 indicates an ETC transaction abnormality between the roadside unit 110 and the vehicle's onboard unit, transaction abnormality information is generated based on the transaction data and sent to the transaction terminal 130, which then performs supplementary operations for the ETC transaction. The transaction abnormality information is used to instruct the transaction terminal to perform supplementary operations for the ETC transaction, including but not limited to retrying the ETC transaction or manually re-entering information (such as the license plate number or payment card number).

[0059] Specifically, the lane control module 120 is configured to generate transaction abnormality information based on the transaction data when the transaction data indicates a transaction abnormality; and send the transaction abnormality information to the transaction terminal 130 .

[0060] In some embodiments of the present invention, the transaction terminal includes a fixed installation terminal or a mobile handheld terminal. In the case where the transaction terminal is a fixed installation terminal, the transaction terminal is installed at a designated location in the transaction area and corresponds one-to-one with the lane control module 120.

[0061] For example: take the lanes including lane 1 and lane 2 as an example; transaction terminal A1 and lane control module B1 are set in lane 1; transaction terminal A2 and lane control module B2 are set in lane 2; transaction terminal A1 and lane control module B1 are set correspondingly; transaction terminal A2 and lane control module B2 are set correspondingly.

[0062] When the transaction terminal is a fixed-installation terminal, the lane control module 120 has pre-established a communication connection with the corresponding transaction terminal 130; alternatively, when the received transaction data indicates a transaction abnormality, the lane control module 120 establishes a communication connection with the corresponding transaction terminal 130; alternatively, after generating transaction abnormality information, the lane control module 120 establishes a communication connection with the corresponding transaction terminal 130.

[0063] In other embodiments of the present invention, the transaction terminal 130 is a mobile handheld terminal.

[0064] In order to provide greater flexibility and convenience for the transaction vehicle during the ETC transaction exception handling process, the transaction terminal 120 can be a mobile handheld terminal. During the abnormal transaction handling process, the staff can hold the transaction terminal 130 and move it to the vehicle to perform the operation without the driver getting out of the vehicle or moving the vehicle.

[0065] When the transaction terminal 130 is a mobile handheld terminal, the same transaction terminal 130 can be communicatively connected with different lane control modules, so that the same transaction terminal 130 can be used to process ETC abnormal transactions in different lanes.

[0066] For example: take lanes including lane 1 and lane 2 as an example; a lane control module C is set in lane 1; a lane control module D is set in lane 2; when there is a vehicle with an abnormal ETC transaction in lane 1, the staff member moves the handheld transaction terminal 130 to the vehicle in lane 1, communicates with the lane control module C and performs an ETC supplementary transaction; when there is a vehicle with an abnormal ETC transaction in lane 2, the staff member moves the handheld transaction terminal 130 to the vehicle in lane 2, communicates with the lane control module D and performs an ETC supplementary transaction.

[0067] When the same transaction terminal 130 needs to be used to handle abnormal ETC transactions in different lanes, in order to ensure that the transaction terminal 130 can establish a communication connection with the correct lane control module 120, it is also necessary to determine the lane control module 120 that conducts ETC transactions with the vehicle based on the positioning information of the transaction terminal 130.

[0068] Based on this, in some embodiments of the present invention, when the transaction terminal 130 is a mobile handheld terminal, the transaction terminal 130 includes a satellite positioning submodule.

[0069] The satellite positioning submodule is used to communicate with positioning satellites to obtain satellite positioning information corresponding to the transaction terminal 130. After obtaining the satellite positioning information through the satellite positioning submodule, the mobile terminal 120 determines the lane and the corresponding lane marker based on the location coordinates indicated by the satellite positioning information and the lane information marked on the pre-set lane map. The lane marker is used to determine the lane control module 120 with which to establish a communication connection. The lane marker can be a number, a letter, a symbol, or any combination thereof. This embodiment does not limit the implementation of the lane marker.

[0070] For example: take lanes including lane 1 and lane 2 as an example; lane control module C is set in lane 1; lane control module D is set in lane 2; when there is a vehicle with abnormal ETC transaction in lane 1, the staff moves the handheld transaction terminal 130 to the side of the vehicle in lane 1; the transaction terminal 130 automatically obtains satellite positioning information, and after determining that the current lane is lane 1 based on the satellite positioning information, it communicates with the lane control module C and performs an ETC supplementary transaction.

[0071] After moving to the lane where the vehicle with the abnormal transaction is located, the staff uses the transaction terminal 130 to obtain the satellite positioning information of the current position, and determines the lane identification of the vehicle based on this information, so as to accurately identify and connect to the corresponding lane control module 120. It is suitable for large parking lots or environments with multiple parallel lanes, and can effectively avoid data errors or ETC transaction failures caused by incorrect lane identification.

[0072] Specifically, the transaction terminal 130 is also used to: obtain satellite positioning information through the satellite positioning submodule after moving to the lane where the vehicle is located; determine the lane identification based on the satellite positioning information; establish a communication channel with the lane control module 120 based on the lane identification; and the lane identification and the lane control module have a one-to-one correspondence.

[0073] In complex operating environments, such as large parking lots or multiple parallel lanes, relying directly on satellite positioning may be affected by factors such as signal interference and building obstructions, resulting in inaccurate positioning. Therefore, by pre-setting an electronic fence, the transaction terminal 130 can be given a clear geographical range, ensuring that it can accurately identify its location, thereby improving the accuracy and reliability of matching with the correct lane control module 120.

[0074] In some embodiments of the present invention, the transaction terminal 130 pre-stores electronic fence information, including the shape, size, and geographic location coordinates of the electronic fence.

[0075] The geo-fence acts as a virtual safety boundary, allowing only transaction terminals 130 within a specific geo-fence to attempt to establish a connection with the lane control module 120. By pre-defining the operating area using the geo-fence, it is possible to quickly verify in the initial stage that the transaction terminal 130 is within the correct area, helping to eliminate erroneous attempts that are not within the area, simplifying the subsequent matching process, and making the entire operation process more efficient and convenient.

[0076] Specifically, determining the lane marking based on the satellite positioning information includes: the transaction terminal 130 compares the satellite positioning information with the electronic fence information to obtain a comparison result; when the comparison result indicates that the transaction terminal is located within the electronic fence, matching the satellite positioning information with the lane information on the preset lane map to determine the lane marking.

[0077] After the transaction terminal 130 determines the lane identification, a communication channel is established with the lane control module 120 based on the lane identification.

[0078] In some embodiments of the present invention, the communication channel between the lane control module 120 and the transaction terminal 130 is constructed based on the Bluetooth submodule. Figure 2 As shown, the lane control module 120 further includes a Bluetooth submodule 1210 .

[0079] In some embodiments of the present invention, the Bluetooth submodule 1210 is connected to the lane control module via a serial communication interface (e.g., an RS232 interface). The module identifier of the Bluetooth submodule 1210 is the same as the lane identifier. The module identifier of the Bluetooth submodule 1210 can be a number, a letter, a symbol, or any combination thereof. This embodiment does not limit the implementation of the module identifier.

[0080] The module identification of the bluetooth submodule 1210 is configured as a bluetooth name that can be searched by other devices. This configuration allows other devices to find and establish a connection with the bluetooth submodule 1210 by identifying the specific name to ensure the accuracy and reliability of communication between devices.

[0081] Based on this, after the transaction terminal 120 determines the lane identification of the lane through satellite positioning information, the lane identification is matched with the currently searchable Bluetooth name to identify the Bluetooth submodule 1210 and establish a communication connection.

[0082] Specifically, the transaction terminal 120 is further configured to obtain the Bluetooth submodule 1210 based on the lane identification query; and establish a Bluetooth connection with the Bluetooth submodule 1210 to establish a communication channel between the transaction terminal 130 and the lane control module 120 .

[0083] When the staff member moves the handheld transaction terminal 130, in order to avoid the transaction terminal 130 connecting to other lane control modules 120 before reaching the lane where the vehicle with abnormal transaction is located, in some embodiments of the present invention, the transaction terminal 130 will only obtain satellite positioning information after receiving the abnormal transaction processing instruction.

[0084] Specifically, the transaction terminal 130 is further configured to execute the step of acquiring satellite positioning information through the satellite positioning submodule when receiving the abnormal transaction processing instruction.

[0085] Among them, the abnormal transaction processing instruction is generated by the transaction terminal 130 when it receives a trigger operation acting on the abnormal transaction processing control. At this time, the transaction terminal 130 is also provided with an abnormal transaction processing control; or, the abnormal transaction processing instruction is an instruction input by the transaction terminal 130 through the virtual control in the image interface on the touch screen. This embodiment does not limit the implementation method of inputting the abnormal transaction processing instruction.

[0086] In addition, after the lane control module 120 generates transaction abnormality information, in order to ensure that the staff can handle the ETC abnormal transaction in time, the lane control module 120 also includes an information prompt component for outputting prompt information, including text and / or sound prompt information, to remind the staff of the lane where the abnormal transaction occurred and handle the abnormal transaction.

[0087] Specifically, after generating the transaction abnormality information, the lane control module 120 is further used to: output prompt information; the prompt information is used to prompt the user to input abnormal transaction processing instructions through the abnormal transaction processing control or the graphic interface on the transaction terminal.

[0088] In actual implementation, the transaction terminal 130 may determine the lane control module 120 to which a communication connection is to be established through a physical connection control provided thereon, or may select a virtual control in a graphical user interface on a touch screen display to establish a connection with a specific lane control module 120. This embodiment does not limit the manner in which the transaction terminal 130 establishes a communication connection with the lane control module 120.

[0089] After the transaction terminal 130 successfully establishes a communication connection with the corresponding lane control module 120 , the lane control module 120 sends transaction abnormality information to the transaction terminal 130 based on the communication connection.

[0090] When the transaction terminal 130 receives transaction anomaly information from the lane control module 120, it broadcasts a radio frequency signal to establish a communication channel with the vehicle's onboard unit (OBU). After receiving the broadcast signal, the OBU enters communication mode and establishes a secure and reliable communication channel with the transaction terminal 130, including mutual identity verification and a secure handshake.

[0091] In some embodiments of the present invention, the transaction terminal 130 transmits a Dedicated Short-Range Communications (DSRC) broadcast signal via a built-in or external 5.8 GHz radio frequency module.

[0092] After the communication channel is established, the transaction terminal 130 will request the vehicle-related information (such as vehicle model, license plate number, etc.) and the vehicle-related information (such as vehicle-related information version number, last transaction record, etc.) of the vehicle-related information. After obtaining the information, the transaction terminal 130 will complete the ETC transaction according to the instructions of the transaction abnormality information.

[0093] To prevent interference from the RSU's RF signal with the OPU awakened by the transaction terminal 130 during transactions between the transaction terminal 130 and the OPU, and to ensure communication clarity and stability during abnormal transaction processing, the RSU's RF signal must be disabled before the transaction terminal 130 sends a broadcast signal. This ensures a pure and reliable communication environment during the upcoming abnormal transaction. Disabling the RSU's RF signal prevents unnecessary electromagnetic interference with the newly awakened OPU, thereby ensuring the accuracy and integrity of data exchange.

[0094] In some embodiments of the present invention, the transaction terminal 130 sends an exception handling request to the lane control module 120. Upon receiving the exception handling request, the lane control module 120 disables the radio frequency signal of the roadside unit 110 to prevent the radio frequency signal of the roadside unit 110 from affecting the supplementary operations of the transaction terminal 120. After successfully disabling the radio frequency signal of the roadside unit 110, the lane control module 120 generates and returns an exception handling response instruction to inform the transaction terminal 130 that the supplementary operations of the ETC transaction can be performed.

[0095] Specifically, the transaction terminal 130 is further configured to generate an exception handling application instruction and send the instruction to the lane control module 120 upon receiving transaction exception information.

[0096] The lane control module 120 is further configured to shut down the radio frequency signal of the roadside unit 110 upon receiving an exception handling application instruction; generate an exception handling response instruction and return it to the transaction terminal 130 .

[0097] The transaction terminal 130 is also used to broadcast a radio frequency signal when it receives an exception handling response instruction, so that the vehicle's on-board unit establishes a communication channel with the transaction terminal 130 when it receives the broadcast radio frequency signal, and returns vehicle information and on-board unit information through the communication channel; when receiving the vehicle information and on-board unit information; based on the vehicle information and on-board unit information, it supplements and completes the ETC transaction in accordance with the instructions of the transaction exception information, generates a supplementary transaction message and sends it to the lane control module 120 to complete the ETC transaction.

[0098] Furthermore, to further prevent the broadcast signal from the transaction terminal 130 from interfering with other vehicles in the current lane undergoing normal ETC transactions, the lane control module 120 must first confirm whether any other vehicles are currently transacting in the lane. If a transaction is detected, the lane control module 120 will temporarily wait until the transaction is complete. This maintains the efficiency of the entire system while also preventing potential errors or confusion caused by multiple transactions occurring simultaneously. Once it is confirmed that no other vehicles are currently transacting in the lane, the roadside unit 110's RF signal is immediately deactivated, allowing the transaction terminal 130 to safely transmit its broadcast signal and begin the abnormal transaction handling process.

[0099] Upon receiving the exception handling request, the lane control module 120 determines the current lane status. If other vehicles are present, the module waits for them to complete their transactions. If no other vehicles are present or the transactions are complete, the module controls the roadside unit 110 to disable the RF signal and generates an exception handling response instruction, which it returns to the transaction terminal 130.

[0100] After receiving the exception handling response instruction, the transaction terminal 130 determines that there are no other transaction vehicles in the current lane, and generates and sends a broadcast signal.

[0101] Specifically, the lane control module 120 is also used to determine the current lane condition when receiving an exception processing application instruction; when the current lane condition indicates the presence of other transaction vehicles, wait for other transaction vehicles to complete the ETC transaction; when the transaction is completed, turn off the radio frequency signal of the roadside unit; generate an exception processing response instruction, and send it to the transaction terminal 130.

[0102] To more accurately monitor the status of vehicles in the lane, the ETC abnormal transaction processing system also includes a lane entry coil module. The lane entry coil submodule is connected to the lane control module to monitor the status of vehicles entering the current lane.

[0103] In some embodiments of the present invention, the ETC abnormal transaction processing system further includes a lane entry coil module; the lane entry coil submodule is communicatively connected to the lane control module for monitoring vehicle entry into the current lane.

[0104] Specifically, determining the current lane condition includes: determining whether there are other vehicles entering the current lane through the lane entry coil module, and if there are other vehicles entering the current lane, determining the existence of other transaction vehicles in the current lane; or, if there are other vehicles in the transaction area, determining the existence of other transaction vehicles in the current lane.

[0105] After receiving the supplementary transaction message from the transaction module 130, the lane control module 120 must verify the supplementary transaction message, including but not limited to data format verification, data integrity verification, identity verification, and logical consistency verification, to ensure the correctness of the supplementary transaction. If the supplementary transaction message passes verification, the lane control module 120 merges the supplementary transaction message with the previously stored abnormal transaction message to form a complete transaction record, which is securely stored in the system database. The transaction anomaly is corrected, providing complete data support for subsequent data analysis and auditing.

[0106] After completing the merge storage operation, the lane control module 120 will re-enable the radio frequency signal of the roadside unit 110 to resume the normal ETC transaction process.

[0107] The lane control module 120 is also used to generate an abnormal transaction message based on the transaction data when the transaction data indicates an abnormal transaction; verify the supplementary transaction message when receiving the supplementary transaction message; obtain the abnormal transaction message through fuzzy matching query when the verification passes; merge the supplementary transaction message with the abnormal transaction message to obtain a complete transaction message and upload it to a designated server for storage; and turn on the radio frequency signal of the roadside unit.

[0108] In actual implementation, when handling complex abnormal situations or performing system maintenance, the automatic control of the RSU's 110 RF signal by the lane control module 120 may not meet actual on-site needs. To enable personnel to adjust the RSU 110 in real time based on actual conditions and ensure smooth operation, the RSU 110 can also be manually controlled to turn on or off RF information through the transaction terminal 130.

[0109] In some embodiments of the present invention, the transaction terminal 130 establishes a connection with the lane control module 120 via the Bluetooth submodule 1210 and simultaneously obtains the lane control module 120's control authority over the roadside unit 110. In this case, the transaction terminal 130 is also provided with a roadside unit control component. By triggering the roadside unit control component, the roadside unit 110 is controlled to turn on or off the radio frequency signal. Alternatively, the roadside unit 110 is controlled to turn on or off the radio frequency signal via a virtual control in a graphical interface on the touch screen display of the transaction terminal 130. This embodiment does not limit the implementation method for controlling the roadside unit 110 to turn on or off the radio frequency signal.

[0110] Specifically, the transaction terminal 130 is also used to turn on or off the radio frequency signal of the roadside unit according to the instructions of the roadside unit control instruction when receiving the roadside unit control instruction; the roadside unit control instruction is an instruction input by the user through the roadside unit control control or image interface on the transaction terminal.

[0111] In addition, reference Figure 2 To further enhance the user experience and system automation, the ETC abnormal transaction processing system also includes a barrier module 140, which is in communication with and closely cooperates with the lane control module 120. If the supplementary transaction message passes verification, the lane control module 120 will issue a command to control the barrier module 140 to lift and release the vehicle, simplifying the vehicle passage process, reducing the need for manual intervention, and improving overall service efficiency.

[0112] Specifically, the lane control module 120 is further configured to control the barrier module 140 to lift and release the vehicle when the supplementary transaction message is verified to be successful.

[0113] Alternatively, after the transaction terminal 130 establishes a communication channel with the lane control module 120 , the transaction terminal 130 directly or indirectly obtains control authority of the barrier module 140 through the lane control module 120 , so that the staff can control the barrier module 140 through the transaction terminal 130 .

[0114] Specifically, the lane control module 120 is further configured to send the verification result of the supplementary transaction message to the transaction terminal 130 .

[0115] The transaction terminal 130 is also used to output a prompt message when it receives the inspection result; the prompt message is used to prompt the user to input the railing module control instruction, and the railing module control instruction is an instruction input by the user through the railing module control control or the graphic interface on the transaction terminal 130; when the transaction terminal 130 receives the railing module control instruction, it controls the railing module 140 to be lifted or lowered according to the instructions of the railing module control instruction.

[0116] In summary, the ETC abnormal transaction processing system provided by this embodiment can solve the problem of low success rate and efficiency of ETC abnormal transaction processing. By optimizing the system architecture and interactive process, when the lane control module detects a transaction abnormality, it will generate transaction abnormality information and send it to the transaction terminal; after receiving the abnormal information, the transaction terminal will generate an abnormal processing application instruction and send it to the lane control module; after receiving the application instruction, the lane control module will turn off the radio frequency signal of the roadside unit to avoid interference from the same frequency signal; then, the transaction terminal will establish a communication channel with the vehicle's on-board unit by broadcasting the radio frequency signal, obtain vehicle information and on-board unit information, and complete supplementary operations. While reducing manual intervention and improving processing efficiency, it also effectively solves the problem of interference from the same frequency signal by turning off the radio frequency signal, which can significantly improve the success rate and efficiency of ETC lane abnormal transaction processing.

[0117] In addition, the lane entry coil module monitors the entry of vehicles into the lane, and combined with the logic of the lane control module, it determines whether there are other transaction vehicles, thereby optimizing the exception handling process; it can avoid the confusion caused by multiple vehicles handling exceptions at the same time and improve processing efficiency; at the same time, it can reduce system instability caused by vehicles waiting in queues, shorten the waiting time of vehicles in the lane, and improve user satisfaction.

[0118] In addition, after the supplementary transaction is completed, the abnormal transaction message is queried through fuzzy matching, the supplementary transaction message and the abnormal transaction message are merged to obtain a complete transaction message and upload it. This can ensure the integrity of the transaction data, facilitate subsequent audits and analysis, reduce manual intervention, improve processing efficiency, and reduce operating costs.

[0119] In addition, the transaction terminal is a mobile handheld terminal. It obtains satellite positioning information through the satellite positioning submodule and establishes a communication channel with the lane control module based on the lane marking, which can improve the flexibility and portability of the transaction terminal. The staff can use the same transaction terminal to handle abnormal transactions in different lanes without changing the transaction terminal, further improving the efficiency of handling abnormal transactions; at the same time, it improves the adaptability to complex traffic environments.

[0120] In addition, by using satellite positioning information and electronic fence information to determine lane markings, the possibility of misoperation can be reduced and the accuracy of the system can be improved.

[0121] Figure 3 This is a flowchart of an ETC abnormal transaction processing method provided by one embodiment of the present application. This embodiment uses the method as an example of an ETC abnormal transaction processing system, with each step being performed by a transaction terminal in the ETC abnormal transaction processing system. The method includes at least the following steps S301 to S306:

[0122] Step S301: upon receiving an abnormal transaction processing instruction, obtaining satellite positioning information through the satellite positioning submodule.

[0123] In some embodiments of the present invention, the roadside unit conducts ETC transactions with vehicles in the transaction area via radio frequency signals, obtains transaction data, and sends the transaction data to the corresponding lane control module. The lane control module has a pre-established communication connection with the roadside unit.

[0124] After receiving transaction data, if the transaction data indicates an abnormality, the lane control module generates transaction abnormality information based on the transaction data and prompts the operator to establish a communication channel with the lane control module through the transaction terminal. Once the communication channel is established, the transaction abnormality information is transmitted to the transaction terminal via the communication channel. The transaction abnormality information indicates the supplementary operations required by the transaction terminal for the ETC transaction.

[0125] The abnormal transaction processing instruction is generated by the transaction terminal when it receives a trigger operation acting on the abnormal transaction processing control, and the abnormal transaction processing control is provided on the transaction terminal; or, the abnormal transaction processing instruction is an instruction input by the transaction terminal through the virtual control in the image interface on the touch screen. This embodiment does not limit the implementation method of inputting the abnormal transaction processing instruction.

[0126] In the event of a transaction abnormality between the roadside unit and the on-board unit in the transaction vehicle, the lane control module outputs a prompt message, prompting the staff to enter abnormal transaction processing instructions through the abnormal transaction processing control or image interface on the transaction terminal.

[0127] After receiving the abnormal transaction processing instruction, the transaction terminal obtains satellite positioning information through the satellite positioning submodule.

[0128] Step S302 : Compare the satellite positioning information with the preset electronic fence information. If the transaction terminal is located within the preset electronic fence, match the satellite positioning information with the lane information on the preset lane map to determine the lane identification.

[0129] Step S303: determine the corresponding lane control module through lane identification search and establish a communication channel with the lane control module.

[0130] After establishing a communication channel with the transaction terminal, the lane control module sends transaction abnormality information to the transaction terminal based on the communication channel.

[0131] Step S304: upon receiving the transaction exception information sent by the lane control module, generate an exception handling application instruction and send it to the lane control module.

[0132] After receiving the exception handling application instruction, the lane control module determines the current lane condition; if the current lane condition indicates the presence of other transaction vehicles, it waits for the other transaction vehicles to complete the ETC transaction; if the transaction is completed, it turns off the radio frequency signal of the roadside unit; generates an exception handling response instruction and sends it to the transaction terminal.

[0133] Step S305, when an exception handling response instruction is received, a radio frequency signal is sent so that the on-board unit in the vehicle establishes a communication channel with the transaction terminal when receiving the broadcast radio frequency signal, and returns the vehicle information of the vehicle and the on-board unit information of the on-board unit through the communication channel.

[0134] Step S306, upon receiving the vehicle information and the onboard unit information, complete the supplementary operation based on the vehicle information and the onboard unit information and in accordance with the instructions of the transaction abnormality information, generate a supplementary transaction message and send it to the lane control module to complete the ETC transaction.

[0135] In summary, the ETC abnormal transaction processing method provided in this embodiment can solve the problem of low success rate and efficiency in ETC abnormal transaction processing. By optimizing the system architecture and interaction process, when the lane control module detects a transaction abnormality, it generates transaction abnormality information and sends it to the transaction terminal. After receiving the abnormality information, the transaction terminal generates an abnormality processing application instruction and sends it to the lane control module. After receiving the application instruction, the lane control module turns off the radio frequency signal of the roadside unit to avoid interference from co-frequency signals. Subsequently, the transaction terminal establishes a communication channel with the vehicle's on-board unit by broadcasting the radio frequency signal, obtains vehicle information and on-board unit information, and completes supplementary operations. While reducing manual intervention and improving processing efficiency, it also effectively solves the problem of co-frequency signal interference by turning off the radio frequency signal, which can significantly improve the success rate and efficiency of ETC lane abnormal transaction processing. At the same time, satellite positioning information is obtained through the satellite positioning submodule, and a communication channel is established with the lane control module based on lane markings. This can improve the flexibility and portability of the transaction terminal. Staff can use the same transaction terminal to process abnormal transactions in different lanes without having to change the transaction terminal, improving adaptability to complex traffic environments and further improving the efficiency of abnormal transaction processing.
