A terminal activation method based on an ETC device and a related system

Abstract

This application proposes a terminal activation method and related system based on ETC devices. When a vehicle passes through its corresponding area, the Roadside Unit (RSU) reads the response command from the target ETC device, which includes the device number and removal status. The terminal system first compares the device number with a local list of devices to be activated. If a match is found, the image recognition unit obtains the vehicle's image data and matches it with the registered image data in the list. Only when a match is successful and the removal status is "inactive" does the RSU issue an activation command. After successful activation, the RSU reports the device number, image data, and activation time. The ETC issuance service system then updates the activation status and removes the device number from the list. This application enables accurate activation during roadside passage without the user's awareness, avoiding the learning cost and Bluetooth dependency of self-activation, and reducing crosstalk and the risk of accidental activation.

Description

Technical Field

[0001] This application relates to the field of intelligent transportation, and more specifically, to a terminal activation method and related system based on ETC devices. Background Technology

[0002] Electronic Toll Collection (ETC) devices are widely used in highway and parking lot toll collection scenarios. With the development of online services, users apply for ETC devices through internet channels such as banks or payment platform apps: users submit their identification information and bind their registered accounts online. After the ETC issuing service agency approves the application, a salesperson issues the ETC device, writing a unique identifier, user information, and vehicle information into the ETC device, and then mails the ETC device to the user via logistics.

[0003] In existing technologies, after receiving the ETC device, users need to install it on the vehicle's windshield according to instructions and activate it themselves through the official app or mini-program. However, this self-activation method has a high learning curve for users, the activation steps are cumbersome, and operation failures occur frequently. Furthermore, the activation process relies on the user's mobile phone's Bluetooth function, and some mobile phones do not support Bluetooth for ETC devices, or even the ETC devices themselves do not support Bluetooth connectivity. This prevents such ETC devices from being activated via Bluetooth, significantly impacting the activation success rate of online application channels and affecting user experience.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0016] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0017] In the description of this application, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0018] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0019] In the existing technology, the process for users to apply for ETC devices through internet channels is as follows: Users apply for ETC devices online through a bank or payment platform APP, submit their ID card, vehicle registration certificate and other document information and bind their contracted account; after the ETC issuing service agency administrator approves the application, the salesperson issues the ETC device a second time through the issuing system, writes the unique identifier, user information and vehicle information into the ETC device, and mails it to the user via logistics. Figure 1 This is a schematic diagram of the activation process for ETC devices obtained through the internet application channel in the existing technology. (See attached diagram) Figure 1 It demonstrates the original online application channel for ETC activation: After receiving the ETC device, the user needs to install the ETC device on the windshield of the vehicle according to the instructions, and finally activate it by themselves through the official APP or mini-program: First, turn on the Bluetooth switch of the ETC device, then enter the activation page of the APP or mini-program, authorize the corresponding application permissions, and then connect the mobile phone to the ETC device through Bluetooth to complete the activation operation of the ETC device.

[0020] Based on the above process, the existing technology has the following technical problems: First, the activation process is costly to learn and cumbersome. The entire activation process requires users to perform cross-device operations between their mobile phone and the ETC device; errors at any stage can lead to activation failure, and such failures are frequent.

[0021] Secondly, the activation success rate is limited by the Bluetooth environment. A small number of mobile phones have poor Bluetooth support for ETC devices, and some ETC devices themselves do not support Bluetooth connectivity, making activation impossible via Bluetooth. This significantly impacts the activation success rate through online application channels.

[0022] Third, there are obstacles to identifying ETC devices in vehicle traffic scenarios. Specifically, when roadside units interact with ETC devices via radio frequency, if multiple ETC devices exist in the communication area simultaneously, it is difficult to accurately distinguish between them, posing a risk of crosstalk in device identification. Furthermore, identification based solely on the ETC device's own information cannot confirm whether the ETC device matches the current vehicle, thus creating obstacles to processing ETC devices appropriately in traffic scenarios.

[0023] In view of the problems of the prior art, this application introduces an automatic terminal activation mechanism: the responsibility for activating ETC devices is shifted from the user side to the roadside, and the RSU roadside units and their communication links already deployed at toll stations or parking lot entrances and exits are reused. When the user drives through for the first time, the roadside automatically completes the identification and activation of the unactivated ETC device.

[0024] Specifically, the core improvement ideas of this application include the following aspects: Firstly, the list is version-synchronized. The ETC issuance service system periodically generates a local list of devices to be activated according to version, and the terminal system periodically obtains and stores it locally, so that the roadside can quickly confirm whether the passing ETC device is in an activated state when a vehicle passes through.

[0025] Secondly, multiple identity verifications are implemented. Before the activation command is issued, the license plate recognition image, the toll vehicle identification result, and the registered image data in the local list of devices to be activated are compared multiple times to avoid erroneous activation due to mismatch between the vehicle and the ETC device.

[0026] Third, multiple sensing prevents crosstalk. When multiple ETC devices exist in the communication area at the same time, multiple sensing is performed and a unique target ETC device is determined based on the received signal strength indication value of each device, so as to reduce the probability of activation failure due to crosstalk in device identification.

[0027] Fourth, secure activation via the ministerial-level key system. The message authentication code required for the activation command is generated by the ministerial-level key management and service platform. The activation process and commands follow industry standards, thus ensuring the same level of security as paid transactions.

[0028] Figure 2 This is a schematic diagram of the architecture of an ETC toll collection system provided in an embodiment of the present invention. See also... Figure 2 The ETC toll collection system includes a terminal system deployed at toll stations, RSU roadside units and image recognition units set up for each lane, and ETC devices installed on vehicles. In addition, the ETC toll collection system is also connected to the provincial network center, the ministerial key management and service platform, and the ETC issuance service system. Figure 2The example provided illustrates a toll station with three lanes: lane 1, lane 2, and lane 3. Each lane is equipped with a corresponding roadside unit (RSU) and image recognition unit. For example, lane 1 corresponds to RSU-1 and an image recognition unit, lane 2 corresponds to RSU-2 and an image recognition unit, and lane 3 corresponds to RSU-3 and an image recognition unit. It should be noted that the number of lanes, RSUs, and image recognition units are merely examples and are not limited in this application.

[0029] Specifically, the Roadside Unit (RSU) is deployed on the lane side of the toll station or parking lot entrance / exit. It interacts with the ETC device entering the lane's communication area via a dedicated 5.8GHz short-range communication link. The ETC device is an On-Board Unit (OBU) installed on the vehicle. Its system information file records information such as the contract serial number and removal status. The removal status indicates the activation status of the ETC device; for example, a removal status of 0x01 indicates activation, and 0x00 indicates inactivation. An image recognition unit is located on the corresponding lane side to recognize license plates and toll vehicle types, and sends the recognized image data to the terminal system. Optionally, the RSUs and image recognition units in each lane of the same toll station are all connected to the same terminal system, which uniformly performs tasks such as screening the list of vehicles to be activated, image matching, activation status recognition, and issuing activation commands. The RSUs and image recognition units can be separate or partially integrated into the same lane device; this application does not limit this.

[0030] See Figure 2 The terminal system is located at the toll station and communicates with the provincial network center. It is used to periodically obtain the local list of devices to be activated and report the device number, image data, and activation time after successful activation. The provincial network center communicates with the ETC issuance service system to forward the local list of devices to be activated, activation results, and status update information. The terminal system also communicates with the ministerial key management and service platform to send the contract serial number and random number during the activation process and receive the message authentication code returned by the ministerial key management and service platform. Figure 2 The dashed line in the middle is used to indicate communication connection or wireless coverage relationship. When a vehicle equipped with ETC enters any lane, the RSU roadside unit and image recognition unit corresponding to that lane will complete sensing, recognition and activation interaction under the control of the terminal system.

[0031] Optionally, combined Figure 2 The architecture of the ETC toll collection system shown is as follows: Figure 3 This is a flowchart illustrating a terminal activation method based on an ETC device according to an embodiment of the present invention. (See attached diagram.) Figure 3 The method includes: Step 100: When a vehicle passes through the area corresponding to the RSU roadside unit, the RSU reads the response command sent by the vehicle's target ETC device.

[0032] The response command includes the device number and removal status of the target ETC device. Optionally, the RSU obtains the above information by reading the system information file of the target ETC device; the system information file is an EF01 file, which is 99 bytes in total; of which, bytes 11 to 18 record the contract serial number, and byte 27 records the removal status.

[0033] Step 101: The terminal system determines whether the device number exists in the local list of devices to be activated.

[0034] If the condition exists, proceed to step 102; otherwise, end the activation process without affecting normal toll collection and passage.

[0035] Step 102: The terminal system obtains the vehicle's image data through the image recognition unit.

[0036] Step 103: The terminal system matches the image data with the registered image data in the local list of devices to be activated.

[0037] If the match is successful, proceed to step 104; if the match is unsuccessful, end the activation process to avoid accidental activation.

[0038] Step 104: The terminal system identifies the disassembly status.

[0039] If the disassembly status is not activated, then step 105 is executed; if the disassembly status indicates that it is activated, then the current activation process ends to avoid repeated activation.

[0040] Step 105: The terminal system sends an activation command to the target ETC device via the RSU.

[0041] Step 106: The terminal system receives the activation response from the target ETC device.

[0042] Step 107: If the activation response indicates successful activation, the terminal system will report the target ETC device number, image data, and activation time to the ETC issuance service system.

[0043] Step 108: The ETC issuance service system updates the activation status of the target ETC device and removes the device number from the local list of devices to be activated.

[0044] The terminal activation method based on ETC devices provided in this invention involves the Roadside Unit (RSU) reading a response command from the target ETC device, including the device number and removal status, when a vehicle passes through its corresponding area. The terminal system first compares the device number with a local list of devices to be activated. If a match is found, the image recognition unit obtains the vehicle image data and matches it with the registered image data in the list. Only when a match is successful and the removal status is "inactive" is the RSU issuing an activation command. After successful activation, the RSU reports the device number, image data, and activation time. The ETC issuance service system then updates the activation status and removes the device number from the list. This application enables accurate activation during roadside passage without the user's awareness, avoiding the learning cost and Bluetooth dependency of self-activation, and reducing crosstalk and the risk of accidental activation.

[0045] Optionally, the following is about Figure 3 The implementation process of the illustrated procedure is explained by way of example. Continuing with the above-mentioned online application scenario, after receiving the reissued ETC device and installing it on the windshield, the user drives through a highway toll station for the first time.

[0046] Specifically, when a vehicle passes through the RSU's designated area, the RSU senses the ETC device on the vehicle and reads its device number and removal status. After receiving this information, the terminal system first queries the local list of devices to be activated using the device number. If the device number is not in the list, it means that the device does not need to be activated by this lane, and the process ends directly without affecting normal toll collection. If it is in the list, the image recognition unit is triggered to perform license plate recognition and toll vehicle type recognition on the vehicle, and the recognition results are matched with the registered image data in the list to confirm that the current vehicle and the ETC device are indeed the same combination of vehicle and license plate registered at the time of application, avoiding accidental activation of devices applied for by other vehicles. After successful matching, the terminal system further identifies the removal status, and only enters the activation process when it indicates that it is not activated. If it has already been activated (e.g., the user has activated it via Bluetooth), it will not be activated again.

[0047] Next, the terminal system sends an activation command to the target ETC device via the RSU. The ETC device executes the command and sends an activation response. If the activation response indicates successful activation, the terminal system reports the device number, image data, and activation time to the ETC issuance service system. The ETC issuance service system then updates the device's activation status and removes it from its local list of devices awaiting activation. At this point, the ETC device is activated, and the vehicle can proceed with non-stop toll collection for this and subsequent passages.

[0048] It should be noted that, according to testing, when a vehicle passes through the ETC terminal at a speed of no more than 20 km / h, the above activation process can be completed within 66 milliseconds, without affecting the normal passage of the vehicle.

[0049] In scenarios with dense traffic, multiple ETC devices may exist simultaneously within the communication area of ​​the RSU. If the activation target is determined directly based on a single sensor reading, misreading the device IDs of adjacent vehicles could lead to IMEI errors and activation failure. Therefore, in... Figure 3 On this basis, Figure 4 A flowchart illustrating another terminal activation method based on an ETC device provided in this embodiment of the invention is shown below. Figure 4 Step 100 includes: Step 100-1: When there are multiple ETC devices in the communication area of ​​the RSU, the RSU roadside unit sends the first broadcast sensing command.

[0050] Step 100-2: The RSU receives the device number of all ETC devices to be identified within the communication area.

[0051] Step 100-3: The RSU records the device number of each ETC device to be identified and the corresponding received signal strength indication value, generating an initial candidate list.

[0052] Step 100-4: The RSU sequentially sends secondary directional sensing commands to each ETC device in the initial candidate list to update the received signal strength indication value of each ETC device to be identified.

[0053] Step 100-5: The RSU roadside unit sends three directional sensing commands to each ETC device to be identified in sequence to update the received signal strength indication value of each ETC device to be identified again.

[0054] Step 100-6: The terminal system takes the average of the three received signal strength indication values ​​of each ETC device to be identified, and selects the ETC device with the highest average value and the smallest fluctuation as the target ETC device.

[0055] Step 100-7: RSU reads the device number and disassembly status of the target ETC device.

[0056] In this example, the Received Signal Strength Indication (RSSI) is used to characterize the strength of the response signals received by the RSU from each ETC device. Specifically, the vehicle where the target ETC device is located is usually closest to the RSU antenna, resulting in a relatively higher and more stable signal strength. By sensing three times and averaging the signal strength, the randomness of a single sampling can be avoided, and the target ETC device can be uniquely identified from multiple ETC devices with a high probability. All subsequent activation commands are addressed based on the device number of the target ETC device to reduce the probability of activation failure due to inconsistent device numbers.

[0057] Optionally, in this embodiment, activation is performed only on the finally determined target ETC device for each passage; for other ETC devices that were not processed in the initial candidate list, their status remains inactive, and the sensing mechanism of this embodiment will be triggered again to process them when the corresponding vehicle passes through again.

[0058] Therefore, in Figure 3 On this basis, Figure 5 A flowchart illustrating another terminal activation method based on an ETC device provided in this embodiment of the invention is shown below. Figure 5 Step 102 includes: Step 102-1: The terminal system acquires the license plate recognition image of the vehicle through the image recognition unit.

[0059] Step 102-2: The terminal system obtains the vehicle type identification result for toll collection through the image recognition unit.

[0060] See also Figure 5 Step 103 includes: Step 103-1: The terminal system identifies the license plate number from the license plate recognition image.

[0061] Step 103-2: The terminal system compares the license plate number with the corresponding record in the local list of devices to be activated.

[0062] If the match is successful, proceed to step 103-3; otherwise, confirm the unsuccessful match and end the activation process.

[0063] Step 103-3: The terminal system compares the toll vehicle identification result with the corresponding toll vehicle recorded in the local list of devices to be activated.

[0064] Step 103-4: Confirm successful matching.

[0065] In this embodiment, the license plate recognition image and the toll vehicle recognition result correspond to the two dimensions of vehicle identity and vehicle attributes, respectively. The license plate number is compared first, and then the toll vehicle is compared. When the license plate is similar or the recognition confidence is insufficient, the vehicle model dimension can be used for secondary constraint. Only when both of them are consistent with the registered image data of the local list of devices to be activated is the matching confirmed to be successful. This allows the binding relationship between "vehicle" and "signature" to be cross-validated before activation, avoiding the mistaken activation of registered devices on adjacent vehicles or unregistered vehicles.

[0066] Optionally, the following provides a possible implementation method for generating and sending activation instructions. Figure 3 On this basis, Figure 6 A flowchart illustrating another terminal activation method based on an ETC device provided in this embodiment of the invention is shown below. Figure 6 Step 105 includes: Step 105-1: The terminal system sends a read command to the target ETC device through the RSU, and the target ETC device returns the contract serial number and random number.

[0067] Step 105-2: The terminal system sends the contract serial number and random number to the ministerial key management and service platform, which then generates a message authentication code and returns it.

[0068] Step 105-3: The terminal system concatenates the message authentication code into an activation command according to the application protocol data unit format.

[0069] Step 105-4: The terminal system sends an activation command to the target ETC device via the RSU.

[0070] The Message Authentication Code (MAC) is generated by the ministerial-level key management and service platform based on the contract serial number and a random number. It is used by ETC devices to verify the legitimacy of the activation command's origin. Specifically, the activation command can adopt the Application Protocol Data Unit (APDU) format, which consists of six parts: CLA, INS, P1, P2, Lc, and DATA. In one possible implementation, the OBU activation command can be obtained by concatenating "04D6811A0501" with the MAC returned by the ministerial-level key management and service platform.

[0071] Optionally, after executing the activation command, the ETC device returns a response code. If the response code is 0x9000, it indicates successful activation, and the ETC device will flash its light and emit a prompt sound; if it is any other response code, it indicates activation failure.

[0072] In this embodiment, the message authentication code of the activation command is generated by the departmental key management and service platform based on the contract sequence number and a random number. The terminal system is only responsible for assembling the code according to the APDU format, and the RSU is only responsible for transparent transmission. The key and MAC calculations are not stored on the roadside. The random number gives each activation command a one-time characteristic, the six-segment structure of the APDU ensures that the command fields can be parsed by the OBU according to the specifications, and the response code 0x9000 provides a clear success criterion. Therefore, the activation process maintains the same level of security as the charging transaction, and the failure can be quickly located based on the response code.

[0073] Optionally, for the activation reporting mechanism in step 107 above, the following is a possible implementation method: the terminal system sends the device number, image data and activation time of the ETC device to the provincial network center; the provincial network center forwards the device number, image data and activation time of the ETC device to the ETC issuance service system.

[0074] It should be noted that after the license plate recognition image and lane image are uploaded along with the activation report, they can be saved by the ETC issuance service system and uploaded to the provincial audit system to provide evidence for audit business.

[0075] Optionally, before the example step 100 above, a mechanism for synchronizing the local list of devices to be activated may also be included. One possible implementation is that the terminal system periodically obtains the local list of devices to be activated from the provincial network center and stores it locally.

[0076] Specifically, the ETC issuance service system generates a new version of the local list of devices to be activated every hour, using a version number format of year, month, day, and hour (YYYYMMDDHH). This list includes information such as device number, ETC card number, license plate number, license plate color, toll vehicle type, and activation status. If a user successfully activates the device via Bluetooth after the list is generated, the ETC issuance service system removes the corresponding device from the local list and generates a new version. The terminal system retrieves the latest version of the local list of devices to be activated from the provincial network center every hour and stores it in its local database, ensuring consistency between the local list and the issuance service side.

[0077] Optionally, for activation failure, this application provides a possible handling mechanism: if the activation response indicates activation failure, the terminal system records the activation failure information and ends the process, waiting for the vehicle to pass through again to trigger step 100.

[0078] Specifically, when activation fails, the reporting process in step 107 will not be executed to avoid reporting invalid data; at the same time, the terminal system will not block the lane to ensure traffic efficiency; since the ETC device is still in an inactive state, the above activation process will be retried the next time it passes through, thus forming a self-correcting retry mechanism.

[0079] Optionally, the above system-side embodiments describe the activation process from the perspective of the ETC toll collection system as a whole. To more clearly illustrate the execution logic of the RSU roadside unit in this process, the following description is from the perspective of the RSU roadside unit alone. Figure 7 This is a flowchart illustrating another terminal activation method based on an ETC device provided in an embodiment of the present invention. This method is applied to an RSU roadside unit, which is deployed at a toll station and connected to the terminal system. See [link to relevant documentation]. Figure 7 The method includes: Step 200: When the vehicle passes through the communication area of ​​the RSU roadside unit, read the response command sent by the target ETC device of the vehicle.

[0080] Optionally, when a vehicle is passing through, it senses and reads the response commands of the target ETC device via a dedicated 5.8GHz short-range communication link.

[0081] Step 201: Send the device number and disassembly status to the terminal system.

[0082] Step 202: Receive the activation command issued by the terminal system.

[0083] As mentioned in the previous example, the activation command is generated by the terminal system after confirming that the device number exists in the local list of devices to be activated, that the vehicle's image data matches the registered image data in the local list of devices to be activated, and that the disassembly status indicator is not activated.

[0084] Step 203: Send an activation command to the target ETC device.

[0085] Step 204: Receive the activation response from the target ETC device and forward the activation response to the terminal system.

[0086] The terminal activation method based on ETC devices provided in this invention involves the Roadside Unit (RSU) reading the response command of the target ETC device when a vehicle enters the communication area, and sending the device number and disassembly status to the terminal system. After the terminal system confirms that the list is matched, the image is matched, and the disassembly status is not activated, and generates an activation command, the RSU receives and issues the activation command, and then forwards the activation response from the target ETC device back to the terminal system. Thus, the RSU only handles sensing, forwarding, and link interaction, while the determination of the list, image, and activation status is centralized in the terminal system. This reuses existing communication links to complete vehicle-to-infrastructure (V2I) interaction, avoids introducing complex business decisions on the RSU side, and allows activation to be completed automatically the moment the vehicle passes.

[0087] Optionally, for the sensing mechanism of the RSU roadside unit, i.e., step 200, the following is a possible implementation: When multiple ETC devices exist in the communication area, send an initial broadcast sensing command; receive the device number of each ETC device to be identified responding in the communication area; record the device number of each ETC device to be identified and its corresponding received signal strength indication value, and generate an initial candidate list; send a second directional sensing command to each ETC device to be identified in the initial candidate list in sequence to update the received signal strength indication value of each ETC device to be identified; send a third directional sensing command to each ETC device to be identified in sequence to update the received signal strength indication value of each ETC device to be identified again; send the three received signal strength indication values ​​of each ETC device to be identified to the terminal system, and receive the device number of the target ETC device determined by the terminal system; wherein, the target ETC device is the ETC device with the highest average value and the smallest fluctuation of the three received signal strength indication values; read the response command sent by the target ETC device.

[0088] It should be noted that in this embodiment, the calculation of the average value of the three received signal strength indication values ​​and the determination of the target ETC device are performed by the terminal system; in another possible implementation, the above average value calculation and the determination of the target ETC device can also be performed locally by the RSU roadside unit, which is not limited here.

[0089] By placing the broadcasting, orientation, and recording actions of the three sensing actions on the RSU roadside unit, and delegating the average value calculation and target determination to the terminal system or optionally the RSU local unit, the sensing link can be brought closer to the radio frequency field and the judgment strategy can be brought closer to the business data. Regardless of which side the judgment is deployed on, the average value and fluctuation of the three RSSIs are used as a unified criterion to ensure the interpretability of the target ETC device selection and to retain deployment flexibility for different toll station computing power and link conditions.

[0090] Optionally, a possible implementation for forwarding activation instructions for RSU roadside units is as follows: receiving a read instruction sent by the terminal system and forwarding the read instruction to the target ETC device; receiving the contract serial number and random number returned by the target ETC device and forwarding the contract serial number and random number to the terminal system; receiving an activation instruction issued by the terminal system; wherein, the activation instruction is obtained by the terminal system by concatenating the message authentication code according to the application protocol data unit format; the message authentication code is generated by the ministerial key management and service platform based on the contract serial number and random number.

[0091] The activation command is obtained by the terminal system by concatenating the message authentication code according to the application protocol data unit format; the message authentication code is generated by the ministerial key management and service platform based on the contract serial number and a random number. For the specific meanings of the reading command, contract serial number, random number, and activation command in this embodiment, please refer to the corresponding examples in steps 105-1 to 105-3 above, which will not be repeated here.

[0092] Optionally, for the communication link, this application also provides a release mechanism. Specifically, after step 204, it further includes: receiving a closing instruction sent by the terminal system, and releasing the communication link with the target ETC device according to the closing instruction.

[0093] Specifically, regardless of whether the activation is successful or not, the RSU roadside unit will release the communication link after the activation session ends, so as to restore itself to a ready state to serve the next vehicle and avoid occupying communication resources and affecting the passage of subsequent vehicles.

[0094] After the activation response is forwarded, the terminal system issues a shutdown command and the RSU releases the communication link with the target ETC device, which can clearly terminate the activation session regardless of whether it is successful or not. The RSU returns to the ready state in time, avoiding long connections from occupying 5.8GHz link resources. When the next vehicle enters the communication area, the sensing and reading process can be re-established immediately, thereby ensuring continuous service capabilities in high-density traffic scenarios.

[0095] Accordingly, the activation process is described below from the perspective of the terminal system. Figure 8 This is a flowchart illustrating another terminal activation method based on an ETC device provided in an embodiment of the present invention. The method is applied to a terminal system deployed at a toll station and connected to an RSU roadside unit and an image recognition unit. See [link to relevant documentation]. Figure 8 The method includes: Step 300: When a vehicle passes through the area corresponding to the RSU roadside unit, it receives the response command sent by the RSU roadside unit.

[0096] The response command is obtained by the RSU roadside unit reading the target ETC device of the vehicle; the response command includes the device number and removal status of the target ETC device.

[0097] Step 301: Determine if the device number exists in the local list of devices to be activated.

[0098] If the condition exists, proceed to step 302; otherwise, end the activation process.

[0099] Step 302: Obtain vehicle image data through the image recognition unit.

[0100] Step 303: Match the image data with the registered image data in the local list of devices to be activated.

[0101] If a match is successful, proceed to step 304; if a match is unsuccessful, end the activation process.

[0102] Step 304: Identify the disassembly status.

[0103] If the disassembly status indicator is not activated, proceed to step 305; if the disassembly status indicator is activated, end the activation process.

[0104] Step 305: Send an activation command to the target ETC device through the RSU roadside unit.

[0105] Step 306: Receive the activation response forwarded by the RSU roadside unit.

[0106] The activation response is provided by the target ETC device.

[0107] Step 307: If the activation response indicates successful activation, the device number, image data, and activation time of the target ETC device are reported to the ETC issuance service system so that the ETC issuance service system updates the activation status of the target ETC device and removes the device number from the local list of devices to be activated.

[0108] Specifically, the terminal system in this application assumes the responsibility of "decision and control": it maintains a local list of devices to be activated, and when a vehicle passes through, it uses the device number reported by the RSU as the entry point to sequentially perform three checks: list screening, image matching, and activation status recognition. Only after all three checks pass can an activation command be generated and issued, and the activation result is reported based on the activation response. Thus, the terminal system naturally integrates the activation triggering timing with the vehicle's passage behavior, transforming the user's experience from "active operation" to "seamless passage," thereby achieving an activation experience with reduced learning costs. Simultaneously, the serial design of the three checks ensures that activation is only performed when all three conditions are met simultaneously: "device is on the list," "vehicle identification number matches," and "not activated," reducing the risk of accidental activation from a process perspective.

[0109] For step 300 above, the following is a possible implementation: When multiple ETC devices exist within the communication area of ​​the RSU roadside unit, the RSU roadside unit sends an initial broadcast sensing command; receives the device number of each ETC device to be identified reported by the RSU roadside unit; obtains the received signal strength indication value corresponding to each ETC device to be identified and generates an initial candidate list; the RSU roadside unit sequentially sends a second directional sensing command to each ETC device to be identified in the initial candidate list and receives the updated received signal strength indication value of each ETC device to be identified; the RSU roadside unit sequentially sends a third directional sensing command to each ETC device to be identified and receives the updated received signal strength indication value of each ETC device to be identified; the average of the three received signal strength indication values ​​of each ETC device to be identified is taken, and the ETC device with the highest average value and the smallest fluctuation is determined as the target ETC device; and the RSU roadside unit sends a response command.

[0110] This embodiment corresponds to the examples shown in steps 100-1 to 100-7 above. The only difference is that it describes the control and judgment actions of the terminal system in the multiple sensing process from the perspective of the terminal system alone. The specific implementation details will not be repeated here.

[0111] Optionally, one possible implementation of step 302 is: obtaining a license plate recognition image of the vehicle through an image recognition unit; obtaining the vehicle's toll-collecting model recognition result through an image recognition unit.

[0112] Optionally, one possible implementation of step 303 is as follows: identify the license plate number from the license plate recognition image; compare the license plate number with the corresponding record in the local list of devices to be activated; if the license plate numbers match, compare the toll vehicle identification result with the corresponding record in the local list of devices to be activated; if the toll vehicle matches, confirm that the match is successful.

[0113] Optionally, one possible implementation of step 305 is as follows: a read command is sent to the target ETC device via the RSU roadside unit, and the contract serial number and random number forwarded by the RSU roadside unit are received; wherein the contract serial number and random number are returned by the target ETC device; the contract serial number and random number are sent to the ministerial key management and service platform, and the message authentication code returned by the ministerial key management and service platform is received; the message authentication code is concatenated into an activation command according to the application protocol data unit format; and the activation command is sent to the target ETC device via the RSU roadside unit.

[0114] Optionally, one possible implementation of step 307 is to send the device number, image data, and activation time of the target ETC device to the provincial network center, so that the provincial network center forwards the device number, image data, and activation time of the target ETC device to the ETC issuance service system.

[0115] Optionally, before step 300, the process may further include: periodically obtaining a local list of devices to be activated from the provincial network center and storing it locally; wherein, the local list of devices to be activated is periodically generated by the ETC issuance service system according to version number; the version number is in the format of year, month, day and hour.

[0116] Optionally, if the activation response indicates activation failure, one possible implementation is to record the activation failure information and end the current activation process, waiting for the vehicle to pass through again to trigger the step of receiving the response command sent by the RSU roadside unit.

[0117] Optionally, to more clearly illustrate the order and timing of message and data flow between the aforementioned devices and units, the following explanation, using a signaling interaction diagram, outlines the entire automatic activation process for ETC-based terminals, following four stages: synchronization of the list to be activated, device sensing and list screening, activation execution, and activation confirmation and list update. This process involves signaling interactions between the ETC issuance service system, the provincial network center, the ministerial key management and service platform, the terminal system, the image recognition unit, the RSU roadside unit, and the ETC device.

[0118] Optionally, for Phase 1: the list of entities to be activated is synchronized. Figure 9 This is a signaling interaction diagram of the synchronization phase of the list to be activated, provided by an embodiment of the present invention. This phase is executed on an hourly basis before vehicle passage. See [link / reference]. Figure 9This stage includes: Step 400: After completing the secondary issuance, the ETC issuance service system registers the devices and generates a list of devices to be activated on an hourly basis.

[0119] The list of devices to be activated includes a corresponding version number; the version number is in the format of year, month, day, and hour. This secondary issuance refers to the process where, after the basic issuance of an ETC device is completed, the issuing service agency binds the user, vehicle, contracted account, and contract serial number to the device based on the approved application information, generating a pending issuance record. At this point, the ownership of the device has been determined, but the disassembled state is still inactive and it needs to be activated before it can be traded.

[0120] Step 401: The ETC issuance service system publishes the latest version of the list of devices to be activated through the provincial network center.

[0121] The provincial network center serves as the aggregation and forwarding platform within the provincial network toll collection system. It is used to forward the list of entities awaiting activation, activation reports, and status synchronization data between the toll station terminal system and the ETC issuance service system, the ministerial key management and service platform. The functions of this provincial network center can also be implemented by regional network centers, municipal network platforms, clearing and settlement centers, highway operation and management platforms, issuance service access gateways, edge gateways, or cloud access platforms; this application does not limit the scope of these implementations.

[0122] Step 402: The terminal system periodically retrieves the latest version of the list of devices to be activated from the provincial network center.

[0123] Step 403: The terminal system stores the list of devices to be activated locally as the local list of devices to be activated.

[0124] The local list of devices awaiting activation is used for subsequent screening of ETC devices in passing vehicles to ensure they are ready for activation.

[0125] Optionally, for Phase Two: Device Sensing and List Screening. Figure 10 This is a schematic diagram of signaling interaction during the device sensing and list screening phase provided in an embodiment of the present invention. This phase is triggered when a vehicle enters the communication area of ​​the RSU roadside unit. See [link / reference]. Figure 10 This stage includes: Step 404: When a vehicle passes through the area corresponding to the RSU roadside unit, the RSU roadside unit sends the first broadcast sensing command.

[0126] Step 405: Each ETC device to be identified within the communication area responds to the first broadcast sensing command.

[0127] Correspondingly, the RSU roadside unit receives the device number of each ETC device to be identified, records the received signal strength indication value corresponding to each device number, and generates an initial candidate list.

[0128] Step 406: The RSU roadside unit sequentially sends secondary directional sensing commands to each ETC device to be identified in the initial candidate list to update the received signal strength indication value of each ETC device to be identified.

[0129] Step 407: The RSU roadside unit sends three directional sensing commands to each ETC device to be identified in sequence to update the received signal strength indication value of each ETC device to be identified again.

[0130] Step 408: The RSU roadside unit reports the three received signal strength indication values ​​of each ETC device to be identified to the terminal system.

[0131] Step 409: The terminal system takes the average of the three received signal strength indication values, identifies the ETC device with the highest average value and the smallest fluctuation as the target ETC device, and returns the device number of the target ETC device to the RSU roadside unit.

[0132] Step 410: The RSU roadside unit reads the system information file of the target ETC device and obtains the response command.

[0133] Step 411: The RSU roadside unit forwards the response command to the terminal system.

[0134] Step 412: The terminal system determines whether the device number exists in the local list of devices to be activated; if not, the process ends.

[0135] Step 413: If present, the terminal system triggers the image recognition unit to perform license plate recognition and toll vehicle type recognition to obtain vehicle image data.

[0136] Step 414: The terminal system matches the image data with the registered image data in the local list of devices to be activated, and saves the license plate recognition image and lane image; if the license plate number or toll vehicle recognition result corresponding to the license plate recognition image is inconsistent with the registered image data, the process ends.

[0137] Step 415: If the matching is successful, the terminal system will identify the disassembly status; if the disassembly status indicator is activated, the process will end.

[0138] Optionally, for Phase 3: Activate execution. Figure 11 This is a schematic diagram of signaling interaction during the activation execution phase provided in an embodiment of the present invention. See also... Figure 11 This stage includes: Step 416: If the disassembly status indicator is not activated, the terminal system sends a read command to the target ETC device through the RSU roadside unit.

[0139] Step 417: The target ETC device returns the contract serial number and random number; the RSU roadside unit forwards the contract serial number and random number to the terminal system.

[0140] Step 418: The terminal system sends the contract serial number and random number to the ministerial key management and service platform to apply for OBU activation.

[0141] Step 419: The ministerial key management and service platform generates a message authentication code based on the contract sequence number and a random number, and returns the message authentication code to the terminal system.

[0142] Step 420: The terminal system concatenates the message authentication code into an activation command according to the application protocol data unit format.

[0143] Step 421: The terminal system sends an activation command to the target ETC device through the RSU roadside unit.

[0144] Step 422: The target ETC device executes the activation command, writes the disassembly status, and emits a flashing light and a prompt sound after successful writing.

[0145] Step 423: The target ETC device sends out an activation response; the RSU roadside unit forwards the activation response to the terminal system.

[0146] The activation response includes a response code; the response code represents the execution result of the activation command.

[0147] Step 424: The terminal system judges the response code; if the activation response indicates activation failure, the activation failure information is recorded and the current activation process ends, waiting for the vehicle to pass through again to trigger step 404.

[0148] Optionally, for Phase Four: Activation Confirmation and List Update. Figure 12 This is a schematic diagram of signaling interaction during the activation confirmation and list update phase provided in an embodiment of the present invention. See [link / reference] Figure 12 This stage includes: Step 425: If the activation response indicates successful activation, the terminal system will send the target ETC device number, image data and activation time to the provincial network center.

[0149] Step 426: The provincial network center forwards the device number, image data, and activation time to the ETC issuance service system.

[0150] Step 427: The ETC issuance service system calls the OBU activation confirmation interface of the ministerial key management and service platform through the intranet dedicated line.

[0151] Step 428: The ministerial-level key management and service platform updates the OBU activation record and returns a success message.

[0152] Step 429: The ETC issuance service system updates the activation status and activation time of the target ETC device, saves the license plate recognition image and lane image and uploads them to the provincial audit system, removes the device number from the local list of devices to be activated, and generates a new version of the local list of devices to be activated every hour.

[0153] Step 430: Update the local activation record in the terminal system.

[0154] Optionally, if the activation response indicates successful activation and the terminal system receives a successful activation report response from the provincial network center or the ETC issuance service system, the terminal system shall update the local activation record; wherein, the local activation record includes, but is not limited to: the device number of the target ETC device, the image data index, and the activation time.

[0155] Step 431: The terminal system sends a shutdown command to the RSU roadside unit; the RSU roadside unit releases the communication link with the target ETC device according to the shutdown command.

[0156] Step 432: The terminal system asynchronously synchronizes the list of successfully activated ETC devices to the provincial network center through the compensation reporting task.

[0157] The compensation reporting task is used to prevent the local list of devices to be activated from remaining due to abnormal activation reporting interface.

[0158] At this point, the entire process of automatic activation of the terminal based on the ETC device is complete.

[0159] To perform the steps of the above examples to achieve the corresponding technical effects, this application also provides a terminal activation system for ETC devices. Specifically, Figure 13 This is a schematic diagram of the architecture of a terminal activation system based on an ETC device provided in an embodiment of the present invention. (See also...) Figure 13 The system 50 includes: an ETC device 500, a terminal system 501 deployed at the toll station, an RSU roadside unit 502, and an image recognition unit 503.

[0160] RSU roadside unit 502 is used to read the response command sent by the target ETC device 500 of the vehicle when the vehicle passes through the area corresponding to the RSU roadside unit 502; wherein, the response command includes the device number and removal status of the target ETC device 500.

[0161] It should be noted that, for the multiple ETC devices 500 involved in this application, referring to the above example, the ETC device 500 with the highest average value and the smallest fluctuation can be identified as the target ETC device 500.

[0162] Terminal system 501 is used to determine whether the device number exists in the local list of devices to be activated; wherein the local list of devices to be activated is stored in terminal system 501; if the device number exists, the image data of the vehicle is obtained through image recognition unit 503; the image data is matched with the registered image data in the local list of devices to be activated; if the match is successful, the disassembly status is identified; if the disassembly status is inactive, an activation command is sent to the target ETC device 500 through RSU roadside unit 502; the activation response is received from the target ETC device 500; if the activation response indicates successful activation, the device number, image data and activation time of the target ETC device 500 are reported to the ETC issuance service system so that the ETC issuance service system updates the activation status of the target ETC device 500 and removes the device number from the local list of devices to be activated.

Figure 14 The RSU roadside unit 60 is deployed at the toll station and connected to the terminal system. The RSU roadside unit 60 includes: The reading module 600 is used to read the response command sent by the target ETC device of the vehicle when the vehicle passes through the communication area of ​​the RSU roadside unit; wherein, the response command includes the device number and removal status of the target ETC device; The receiving module 601 is used to receive the activation command issued by the terminal system; wherein the activation command is generated by the terminal system after confirming that the device number exists in the local list of devices to be activated, that the vehicle's image data matches the registered image data in the local list of devices to be activated, and that the disassembly status indicator is not activated. The sending module 602 is used to send the device number and disassembly status to the terminal system; send an activation command to the target ETC device; receive the activation response from the target ETC device and forward the activation response to the terminal system.

[0164] Optionally, this application also provides a terminal system, specifically...

Figure 15 The terminal system 70 is deployed at the toll station and connected to the RSU roadside unit and the image recognition unit. The terminal system 70 includes: The receiving module 700 is used to receive a response command sent by the RSU roadside unit when a vehicle passes through the area corresponding to the RSU roadside unit; wherein, the response command is obtained by the RSU roadside unit from reading the target ETC device of the vehicle; the response command includes the device number and removal status of the target ETC device; if the device number exists, the image data of the vehicle is obtained through the image recognition unit; and to receive an activation response forwarded by the RSU roadside unit; wherein, the activation response is fed back by the target ETC device. The processing module 701 is used to determine whether the device number exists in the local list of devices to be activated; to match the image data with the registered image data in the local list of devices to be activated; and if the match is successful, to identify the disassembly status. The sending module 702 is used to send an activation command to the target ETC device through the RSU roadside unit if the disassembly status indication is not activated; if the activation response indicates successful activation, the device number, image data and activation time of the target ETC device are reported to the ETC issuance service system so that the ETC issuance service system updates the activation status of the target ETC device and removes the device number from the local list of devices to be activated.
