[0023] The terms used in the following embodiments of the present application are only for the purpose of describing specific embodiments and are not intended to be limiting of the present application. The technical solutions in the embodiments of the present application will be clearly and comprehensively described below in conjunction with the accompanying drawings. Among them, in the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in the text is only a description of the association relationship of associated objects, indicating that three relationships can exist, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0024] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features, and in the description of the embodiments of the present application, unless otherwise specified, "plurality" means two or more.

[0025] First, several terms involved in the embodiments of the present application are introduced:

[0026] Vehicle Identification Number (VIN). VIN is also called the vehicle frame number or 17-digit code. It is the vehicle's ID card and consists of 17 digits (letters and numbers). By reading the VIN code, you can get a lot of information about the vehicle, including the country of production, vehicle manufacturer, vehicle type, model year, production sequence number, etc.

[0027] Electronic Control Unit (ECU). ECU is used to control the driving state of the vehicle and realize its various functions. It mainly uses data collection and exchange of various sensors and buses to judge the vehicle status and the driver's intention and control the vehicle through actuators. Common ECUs include but are not limited to the following: Engine Management System (EMS), Transmission Control Unit (TCU), Body Control Module (BCM), Electronic Stability Program (ESP), Battery Management System (BMS) and Vehicle Control Unit (VCU), etc. The ECU involved in the embodiments of the present application may include any one or more of the above.

[0028] On-Board Diagnostics (OBD). Through the vehicle data and fault codes provided by OBD, vehicle problems can be quickly found and resolved. In the embodiment of the present application, the vehicle detection equipment and the vehicle inspection equipment can be connected to the standardized OBD interface to obtain vehicle data.

[0029] The above are the terms involved in the embodiments of this application.

[0030] At present, public security agencies and relevant departments will use the chassis number to check the vehicle's entire system VIN and the chassis number written into each ECU. The inspection equipment establishes communication with the ECU through the vehicle's OBD interface, reads and parses the VIN information stored in the ECU, and automatically compares the VIN written into each ECU with the vehicle's original data. If all VINs are consistent, the chassis number will be prompted to be consistent, reminding the police that the inspection has passed; if the VIN in a certain ECU is inconsistent with the actual VIN of the vehicle, the chassis number will be prompted to be inconsistent, reminding the inspectors to pay attention to the risk of illegal assembly of the vehicle.

[0031] However, the equipment currently available on the market that checks the vehicle frame number is limited to displaying the immediate results of the current inspection, and cannot trace the vehicle's historical inspections, resulting in the inability to verify the vehicle's past inspections. The data barriers between different local agencies limit information sharing, resulting in the problem of information islands.

[0032] To solve the above problems, the embodiment of the present application establishes a vehicle inspection joint prevention and control system based on vehicle diagnostic technology and big data technology. The system includes a vehicle detection device, a vehicle inspection device, a vehicle and a server. Among them, the vehicle detection device is connected to the vehicle through an integrated interface, collects, stores, compares and analyzes the detection data, and uploads the vehicle detection device identity number ID, inspection location, inspection results, vehicle information and other data to the server. The vehicle inspection device is connected to the vehicle through an integrated interface, and obtains the historical inspection record of the vehicle from the server through the vehicle frame number. If a vehicle has used vehicle detection equipment A and vehicle detection equipment B to check the frame number and the frame number is inconsistent, when the vehicle inspection device is used to detect the vehicle, the vehicle inspection device can trace the historical inspection record of the vehicle and determine whether there are multiple inconsistent inspection results. At the same time, the vehicle inspection device can obtain data including vehicle detection equipment ID, location, inspection results, vehicle information, etc., and realize data sharing in different devices. Among them, different devices belong to different departments or institutions, thereby realizing the joint prevention and control capabilities of problem vehicles between different departments or institutions.

[0033] The following Figures 1 to 8 Hereinafter, the vehicle inspection method, device and related equipment provided in the embodiments of the present application will be introduced.

[0034] Figure 1 The communication system architecture is shown, which is an exemplary architecture diagram of a communication system applicable to the embodiment of the present application. The communication system includes a vehicle detection device 100, a server 200, a vehicle 300 and a vehicle inspection device 400. The vehicle detection device 100 and the server 200 and the vehicle 300 can communicate with each other, and the vehicle inspection device 400 and the server 200 and the vehicle 300 can communicate with each other. In the embodiment of the present application, the communication system is also called an inspection system.

[0035] The vehicle detection device 100 and the vehicle inspection device 400 can be distributed throughout the communication system and can be stationary or mobile. In some embodiments of the present application, the vehicle detection device 100 and the vehicle inspection device 400 can be user equipment (UE), mobile equipment, mobile station, mobile unit, machine to machine (M2M) terminal, wireless unit, terminal device, remote unit, terminal agent, mobile client, etc.

[0036] The vehicle detection device 100 establishes a connection with the ECU in the vehicle 300 through the OBD interface, obtains the original data of the vehicle 300 and the VIN written by each ECU, and checks the VIN written by each ECU with the VIN in the original data of the vehicle 300. If there is a situation where the VIN written by the ECU is inconsistent with the VIN in the original data of the vehicle 300, the vehicle detection device 100 can mark this record as an abnormal record. In the embodiment of the present application, the vehicle 300 can be referred to as a target vehicle.

[0037] The original data of the vehicle 300 is the data set when the vehicle 300 is manufactured and shipped, which is usually a fixed value and will not be modified at will. The vehicle detection device 100 can read the original data in the vehicle 300, such as the original VIN of the ECU. The VIN in the original data of the vehicle 300 is the VIN of the target vehicle.

[0038] The vehicle detection device 100 sends the inspection result and other data obtained in the vehicle 300 to the server 200, and the server 200 receives and stores the inspection result and other data in the vehicle 300.

[0039] The server 200 may include a data management system, and after receiving the detection data sent by the vehicle detection device 100, the detection data of the vehicle detection device 100 is stored in a database through the data management system. The data management system may sort and rank the detection data received by the server 200, for example, according to the VIN in the original data of the vehicle 300, the detection records of the same vehicle 300 detected by different vehicle detection devices 100 are regarded as the detection records of the same group, and are stored in the database in order (such as the time order of the acquisition of the detection records).

[0040] In the server 200, the data received from the vehicle detection device 100 may include the vehicle equipment identification number (Identity document, ID), inspection location, inspection timestamp, vehicle data (such as vehicle model, year, ECU name, ECU original VIN, ECU current VIN, etc.), inspection results (consistent frame number or inconsistent frame number), etc.

[0041] The vehicle inspection device 400 can establish a connection with the ECU in the vehicle 300 through the OBD interface, obtain the VIN in the original data of the vehicle 300, and obtain the inspection record of the vehicle 300 from the server 200 through the VIN. The inspection records stored in the server 200 include normal records with consistent frame number inspection and abnormal records with inconsistent frame number inspection.

[0042] When the number of abnormal records obtained by the vehicle inspection device 400 exceeds the first threshold, the vehicle 300 is judged to be an abnormal vehicle. The first threshold may be 2 times, indicating that special attention needs to be paid to vehicles with 2 or more abnormal detections. The embodiment of the present application does not limit the device for judging abnormal vehicles in the communication system architecture.

[0043] In one embodiment, the vehicle inspection device 400 and the vehicle detection device 100 are the same device. In this case, the vehicle inspection device 400 can execute the execution method of the aforementioned vehicle detection device 100, and the communication system can be a communication system composed of the server 200, the vehicle 300 and the vehicle inspection device 400. Alternatively, the vehicle detection device 100 can execute the execution method of the aforementioned vehicle inspection device 400, and the communication system can be a communication system composed of the vehicle detection device 100, the server 200 and the vehicle 300. The embodiment of the present application does not limit the types of devices specifically included in the communication system.

[0044] It should be understood that Figure 1 The communication system in the embodiment takes the communication of a vehicle detection device 100, a server 200, a vehicle 300 and a vehicle inspection device 400 as an example. In actual applications, the number of vehicle detection devices 100 and vehicle inspection devices 400 in the communication system can be more. In this case, a server 200 can communicate with multiple vehicle detection devices 100 and / or vehicle inspection devices 400 at the same time. In the following introduction, the communication method provided in the embodiment of the present application is applied to Figure 1 The communication system shown. In addition, the method can be performed by two communication devices, such as a first communication device and a second communication device. The first communication device can be a vehicle detection device 100 or a communication device that can support the vehicle detection device 100 to implement the functions required by the method, and of course it can also be other communication devices, such as a chip system. For the second communication device, it can be a vehicle inspection device 400 or a communication device that can support the vehicle inspection device 400 to implement the functions required by the method, and of course it can also be other communication devices, such as a chip system.

[0045] If the embodiment of the present application is applied to Figure 1 The communication system shown in FIG. 1 , the vehicle detection device described below may be Figure 1 The vehicle detection device 100 in the communication system shown in the figure can be a vehicle inspection device. Figure 1 The vehicle inspection device 400 in the communication system shown. It should be noted that the embodiment of the present application is only performed by the vehicle detection device 100, the server 200, the vehicle 300 and the vehicle inspection device 400 as an example, and is not limited to the vehicle detection device 100 and the vehicle inspection device 400.

[0046] based on Figure 1 The communication system shown, Figure 2 The method flow of vehicle inspection is shown.

[0047] S101. The vehicle detection device establishes a connection with the ECU via the OBD interface, and reads and parses the VIN stored in the ECU.

[0048] The vehicle detection device is connected to the vehicle OBD interface to establish a connection with the ECU in the vehicle. The vehicle detection device can obtain data stored in each ECU, including but not limited to the vehicle model, year, ECU name, ECU original VIN, ECU current VIN, etc.

[0049] S102. The vehicle detection device determines whether the VIN stored in the ECU is consistent with the original VIN, and displays the determination result.

[0050] The vehicle detection equipment has a data comparison function, which can automatically compare the VIN code written in each ECU with the original VIN one by one. The original VIN can come from the original data of the vehicle. If the VIN code written in all ECUs is consistent with the original VIN code, the frame number detection is normal, and the vehicle detection equipment feedback frame number is consistent. Figure 3 The vehicle detection device display interface shown in the figure displays a prompt message "VIN is consistent". If the VIN written in a certain ECU is inconsistent with the original VIN, the VIN detection is abnormal, and the vehicle detection device reports that the VIN is inconsistent. Figure 4 The vehicle detection equipment display interface shown has a prompt message "Vehicle frame number inconsistent" displayed on the interface.

[0051] S103. The vehicle detection device uploads the detection related data to the server.

[0052] The vehicle detection equipment can obtain relevant data of the vehicle and upload the data to the server for storage. The relevant data may include the ID of the vehicle detection equipment, the inspection location (which can be obtained through the positioning module of the vehicle detection equipment, such as the Global Positioning System (GPS)), the inspection timestamp, the vehicle data (including but not limited to the vehicle model, vehicle year, ECU name, ECU original VIN, ECU current VIN, etc.), the inspection result (the frame number is consistent or inconsistent), and other data.

[0053] Optionally, the vehicle detection device can encapsulate the data packet in the programming language Java data format (Java Script Object Notation, JSON), and establish an encrypted connection with the server using the secure hypertext transfer protocol (Hypertext Transfer Protocol Secure, HTTPS). With the help of the application programming interface (Application Programming Interface, API) interface, the vehicle detection device can upload the relevant data in the JSON format to the server in real time.

[0054] The vehicle detection equipment has a built-in intelligent threshold monitoring mechanism. When the obtained frame number is inconsistent, the intelligent threshold monitoring mechanism automatically marks the record as an abnormal record and stores it in the database.

[0055] S104. The server records the detection record of the VIN stored in the ECU and the original VIN.

[0056] The server includes a data management system, through which various data sent by the vehicle inspection device can be stored in a database, including abnormal records. The server can store data records of multiple inspections by the vehicle inspection device, which can be historical records of vehicle inspections.

[0057] The data management system can store the records of the same vehicle detected by different vehicle detection equipment as the same group of detection records in the database in order (such as the order in which the detection records were obtained) according to the VIN in the original data of the vehicle.

[0058] S105. The vehicle inspection device establishes a connection with the ECU via the OBD interface and reads the VIN stored in the ECU.

[0059] The way in which the vehicle inspection device is connected to the vehicle OBD interface to obtain the original VIN of the ECU in the vehicle is similar to the way in which the vehicle detection device establishes a connection with the ECU through the OBD interface and reads the VIN stored in the ECU. For details, please refer to the aforementioned S101 step for understanding, which will not be repeated here.

[0060] In one embodiment, the vehicle inspection device and the vehicle detection device are the same device, that is, the original VIN of the vehicle can be obtained in step S101, and S105 is an optional step.

[0061] S106. The vehicle inspection device retrieves historical inspection data of the corresponding vehicle from the database based on the VIN.

[0062] The vehicle inspection device obtains the inspection data record of the corresponding VIN stored in the server based on the VIN in the obtained vehicle. In this way, when the vehicle is inspected by the vehicle inspection device, the historical inspection record of the vehicle can be traced back to determine whether there are multiple inconsistent inspection results. For example, the vehicle inspection device obtains that the vehicle has used vehicle inspection equipment A and vehicle inspection equipment B to inspect the vehicle and the frame number is inconsistent. The vehicle inspection equipment and the vehicle inspection equipment can be located in different regions and belong to different institutions, thereby realizing cross-institutional data sharing and increasing the joint prevention and control capabilities of different departments for problem vehicles.

[0063] S107. The vehicle inspection device displays a prompt message.

[0064] The vehicle inspection device is set with an intelligent threshold. If the number of abnormal records of the vehicle is greater than or equal to the first threshold, the vehicle inspection device will trigger the early warning mechanism, record and judge the vehicle as an abnormal vehicle, and display the vehicle pick-up result. For example, if the vehicle inspection device finds that the number of abnormal records of the vehicle is greater than or equal to 2 times, the inspection personnel will be prompted to pay attention to the problem vehicle through a prompt message. Figure 3 and Figure 4 As shown, a prompt "This vehicle has had multiple inconsistent frame numbers during inspections. Please check the inspection records for details" is displayed at the bottom of the display interface of the vehicle inspection device to remind inspectors and ensure that problem vehicles receive timely attention and processing.

[0065] Optionally, the vehicle inspection device can also display a historical inspection interface. In the historical inspection interface, you can view detailed inspection data on whether the vehicle frame number is consistent, including the vehicle inspection device ID, inspection location, inspection time, and basic vehicle data (including but not limited to vehicle model, vehicle year, ECU name, ECU original VIN, ECU current VIN, etc.). This provides strong support for the management and troubleshooting of problem vehicles.

[0066] In one embodiment, the vehicle inspection device and the vehicle detection device are the same device, and the solution can be executed in multiple vehicle inspection devices. Among the multiple vehicle inspection devices, one of the vehicle inspection devices can obtain the inspection data of other vehicle inspection devices to achieve cross-device data sharing. Exemplarily, vehicle inspection device A can obtain the inspection data of the same vehicle by vehicle inspection device B and vehicle inspection device C through the server. If vehicle inspection device A finds that the vehicle has inconsistent frame numbers detected in both vehicle inspection device B and vehicle inspection device C, a prompt message indicating that the vehicle has multiple inconsistent frame numbers is displayed.

[0067] During the inspection, if the VINs of different ECUs of the vehicle are consistent, the vehicle inspection device will mark the vehicle inspection as normal and display the inspection result of consistent frame numbers on the interface; if the VINs of different ECUs of the vehicle are inconsistent, the vehicle inspection device will mark the vehicle inspection as abnormal and display the inspection result of inconsistent frame numbers on the interface. The vehicle inspection device obtains the historical inspection records of the vehicle corresponding to the VIN. If the number of inconsistent frame numbers detected exceeds a first threshold, a prompt message indicating vehicle abnormality will be displayed on the vehicle inspection device interface.

[0068] based on Figure 2 The vehicle inspection method flow shown is as follows: Figure 3 and Figure 4 The vehicle frame number verification interface is shown.

[0069] For example, Figure 3 As shown, when the vehicle detection device and the vehicle inspection device are the same device, the device displays the frame number provided by the vehicle power system and the independent gateway. The current VIN of the power system is consistent with the current VIN of the independent gateway, for example, both are "LNA001PEA0100112", and the vehicle inspection device marks the vehicle inspection as normal, and displays the inspection result of the consistent frame number in the interface, including prompt information such as "The frame number is consistent" and a prompt symbol located above the prompt information. The vehicle inspection device obtains the historical inspection record of the vehicle corresponding to the VIN, including at least 2 times of detecting inconsistent frame numbers, and displays abnormal vehicle prompt information such as "This vehicle has multiple inconsistent frame numbers. Please check the details in the inspection record" at the bottom of the vehicle inspection device interface.

[0070] For example, Figure 4 As shown, when the vehicle detection device and the vehicle inspection device are the same device, the device displays the frame number provided by the vehicle power system and the independent gateway. During the inspection, the current VIN of the power system is inconsistent with the current VIN of the independent gateway. For example, the current VIN of the power system is "LNA001PEA0100112" and the current VIN of the independent gateway is "LNADHAB24P1237788". The vehicle inspection device marks the vehicle inspection abnormality and displays the inspection result of the inconsistent frame number in the interface, including a prompt message such as "Inconsistent frame number" and a prompt symbol located above the prompt message. The vehicle inspection device obtains the historical inspection record of the vehicle corresponding to the VIN, including at least 2 times of detecting inconsistent frame numbers, and displays a prompt message such as "This vehicle has multiple inconsistent frame numbers. Please check the details in the inspection record" at the bottom of the vehicle inspection device interface.

[0071] like Figure 5 The vehicle detection device provided in the embodiment of the present application is shown, and the device includes:

[0072] The data comparison unit 501 is used to compare the acquired VIN stored in the vehicle ECU with the VIN of the vehicle to determine a comparison result.

[0073] The threshold monitoring unit 502 is used to mark the vehicle as an abnormal vehicle when the VIN stored in the ECU is inconsistent with the VIN of the vehicle.

[0074] The first communication unit 503 is used to communicate with the server and send relevant data of the vehicle for verification.

[0076] The data comparison unit 501 is used to execute the method steps shown in step S102 for determining whether the VIN stored in the ECU is consistent with the original VIN.

[0077] The threshold monitoring unit 502 and the first communication unit 503 are used to execute the method steps shown in step S106, when the number of abnormal records of a vehicle is found to be greater than or equal to the first threshold, and automatically record and determine that the vehicle is an abnormal vehicle.

[0080] The warning unit 601 is used to indicate that the VIN of the vehicle shown has multiple inconsistencies.

[0081] The second communication unit 602 is used to communicate with the server to obtain the inspection record of the vehicle.
