[0041] The embodiment of the present application provides a vehicle fault information processing method, device and storage medium.

[0042] The embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although some embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms, and should not be interpreted as being limited to the embodiments described herein, but rather, these embodiments are provided to more thoroughly and completely understand the present disclosure. It should be understood that the drawings and embodiments of the present application are only for exemplary purposes, and are not intended to limit the scope of protection of the present application.

[0043] In the description of the embodiments disclosed herein, the term "comprising" and its conjugations are to be understood as open-ended, i.e., "including but not limited to". The term "based on" is to be understood as "based, at least in part, on". The term "one embodiment" or "an embodiment" is to be understood as "at least one embodiment". The terms "a first", "a second", etc. are to be understood as "different or identical" objects. Other explicit or implicit definitions can also be included below.

[0044] For ease of understanding, the specific process of the embodiments of the present application is described below. Please refer to FIG. 1. One embodiment of the vehicle fault information processing method in the embodiments of the present application includes:

[0045] 101, when a fault code is detected, acquiring freeze frame data corresponding to the fault code;

[0046] The vehicle fault information processing device is a device specially used to detect and analyze various faults of the automobile. It can be connected to the computer system of the automobile to read fault codes, and can also test the automobile battery alone to obtain battery data, helping repair personnel to determine the location and nature of the fault.

[0047] The vehicle fault information processing device includes an automobile diagnostic instrument, which includes an engine diagnostic instrument, a battery tester, an anti-lock braking system (ABS) diagnostic instrument, a safety airbag (SRS) diagnostic instrument, an automatic transmission diagnostic instrument, etc. Through these devices, the running state of the engine of the automobile, whether the battery is normal, whether the brake system is normal, whether the airbag is faulty, whether the transmission is normal, etc. can be detected.

[0048] In this embodiment, the vehicle fault information processing device detects whether a fault code is scanned. If so, the fault code is recorded.

[0049] If a fault code is found, the vehicle fault information processing device will acquire freeze frame data corresponding to the fault code. Freeze frame data is a kind of snapshot corresponding to the vehicle at the time of fault occurrence, which can provide important information about the state of the vehicle.

[0050] Optionally, the OBD data is detected in real time, and it is judged whether the OBD data contains a fault code; if the OBD data contains the fault code, it is determined that the fault code is detected. Wherein, the vehicle fault information processing device is started and connected to the OBD (On-Board Diagnostics) system of the vehicle. It can be realized through the OBD interface. Then, the vehicle fault information processing device starts scanning the OBD system of the vehicle to detect possible fault codes. Wherein, the fault code is a pre-defined code representing various problems encountered by the vehicle.

[0051] Specifically, referring to FIG. 2, FIG. 2 is a schematic diagram of one specific embodiment of the step 101 of the method for processing vehicle fault information in the embodiment of the present application, and the step 101 includes the following specific implementation:

[0052] 1011, when detecting the fault code, request to select whether to generate a two-dimensional code;

[0053] 1012, when detecting the selection operation of generating the two-dimensional code, acquire the frozen frame data corresponding to the fault code.

[0054] In steps 1011-1012, the user can select whether to generate a two-dimensional code according to his own needs. If the user thinks that the current fault situation is not serious or can be handled by himself, he can choose not to generate a two-dimensional code, so as to avoid the waste of computing resources.

[0055] Specifically, the step 101 further includes the following specific implementation:

[0056] 1013, when detecting the fault code, acquire the frozen frame data corresponding to the fault code and acquire the battery test data;

[0057] 1014, incorporate the battery test data into the frozen frame data.

[0058] Among them, the battery tester detects the battery test data as the frozen frame data, and subsequently, the two-dimensional code corresponding to the battery test data can be output based on the frozen frame data. The user can print the battery test report through the two-dimensional code. This printing method is not only convenient, but also makes the report more operable, such as graphical, editing, etc.

[0059] In steps 1013-1014, by incorporating the battery test data into the frozen frame data, the technician can more comprehensively understand the vehicle state when the fault occurs during vehicle fault diagnosis, including the working condition of the battery. This helps to more accurately locate the fault cause and avoid missing potential problems related to the battery.

[0060] 102, according to a preset two-dimensional code generation algorithm, perform a data processing operation on the fault code and the frozen frame data to obtain the two-dimensional code;

[0061] Specifically, the fault code and the frozen frame data are integrated according to the data format required by the two-dimensional code generation algorithm. The encoded data is converted into a two-dimensional code using a preset two-dimensional code generation algorithm.

[0062] Specifically, referring to FIG. 3, FIG. 3 is a schematic diagram of one specific embodiment of the step 102 of the method for processing vehicle fault information in the embodiment of the present application, and the step 102 includes the following specific implementation:

[0063] 1021、detect the IM state, and obtain a preset vehicle identification code;

[0064] 1022、according to a preset two-dimensional code generation algorithm, perform data processing operations on the IM state, the vehicle identification code, the fault code, and the frozen frame data to obtain the two-dimensional code.

[0065] Specifically, the vehicle identification code, the fault code, the IM state, and the frozen frame data are integrated into a string; a preset QR code (Quick Response Code) generation algorithm is called to convert the string into a matrix; and image generation operations are performed according to the matrix to obtain the two-dimensional code. QR code is a kind of two-dimensional code, which can quickly read information through a specific scanning device. The generation algorithm of QR code mainly includes data encoding, error correction encoding, connection of data and error correction code, data arrangement and padding, and generation of the final QR code. For example: the input data is converted into binary form and encoded according to the encoding rules of QR code to obtain a data string. According to the user-selected error correction level (L, M, Q, H), the encoded data is error correction encoded to obtain an error correction code string. The data string and the error correction code string are connected to form a new string. The connected string is arranged according to the data arrangement rules of QR code, and padded as needed.

[0066] According to the arranged data, the final QR code is generated. This step generates a two-dimensional matrix, each element of which represents a pixel of the QR code and has a value of 0 or 1.

[0067] Among them, the vehicle identification code, the fault code, the IM state and the frozen frame data are integrated into a string, which can realize efficient integration and management of data, and make data processing and transmission more convenient. The two-dimensional code contains the key information of the vehicle, which is very important for fault diagnosis and processing, and helps to improve the efficiency and accuracy of fault processing.

[0068] In steps 1021-1022, by integrating the IM state (detecting the working state of the vehicle emission related system), the vehicle identification code (uniquely determining the information of a vehicle), the fault code (indicating what kind of fault the vehicle has), and the frozen frame data (detailed data of the vehicle when the fault occurs), comprehensive information is provided for fault diagnosis, which helps to improve the accuracy of diagnosis.

[0069] 103、output the two-dimensional code;

[0070] Specifically, the generated two-dimensional code is output. It can be directly displayed on the screen of the vehicle-mounted system.

[0071] 104. When detecting that the user terminal scans the two-dimensional code, send a control authority acquisition request to the user terminal;

[0072] Specifically, the user scans the two-dimensional code generated by the vehicle fault information processing device using a mobile phone or other device, and the two-dimensional code contains the identification information of the vehicle fault information processing device and the command for requesting control authority. When the user terminal device recognizes and parses the two-dimensional code, it will send a confirmation information to the vehicle fault information processing device. When the vehicle fault information processing device receives this confirmation information, it knows that the user has scanned the two-dimensional code, and then sends a control authority acquisition request to the user terminal.

[0073] Optionally, the two-dimensional code contains a specific network connection. When the user device scans the two-dimensional code and attempts to establish this network connection, the vehicle fault information processing device can detect this attempt to connect, thereby knowing that the user has scanned the two-dimensional code and sending a control authority acquisition request to the user terminal.

[0074] Specifically, the step 104 includes the following specific implementation:

[0075] 1041. When detecting that the user terminal scans the two-dimensional code, generate a control authority acquisition request according to a preset control time;

[0076] 1042. Send the acquisition request to the user terminal.

[0077] In steps 1041-1042, by generating a temporary control authority, it can ensure that the user terminal has access to the vehicle fault information within a specific time period after scanning the two-dimensional code. Avoid long-term or permanent authority assignment, reduce the security risk caused by abuse of authority.

[0078] 105. When obtaining the control authority, control the user terminal to send a fault analysis request to the cloud according to the two-dimensional code, wherein the cloud returns fault analysis data to the user terminal in response to the report acquisition request;

[0079] Specifically, when the vehicle fault information processing device obtains the control authority, it will send a command to the user terminal, requiring the user terminal to send a fault analysis request to the cloud according to the information in the two-dimensional code. It can be transmitted to the user device through Bluetooth, Wi-Fi or network communication.

[0080] After the user terminal device receives the command, it parses the information in the two-dimensional code to get the connection address of the cloud and the data (such as the fault code of the car) that needs to be sent. Then, the user terminal device sends a fault analysis request to the cloud through network connection.

[0081] The cloud server receives the fault analysis request and performs fault analysis according to the data in the request. The cloud server can use cloud computing technology to analyze the fault data through big data analysis and machine learning, and obtain the cause of the fault and the solution.

[0082] The cloud server returns the fault analysis data to the user terminal device. After receiving the data, the user terminal device can display the data to the user to help the user understand the fault condition of the vehicle and take appropriate measures to solve the problem.

[0083] 106、Detecting that the user terminal receives the fault analysis data, control the user terminal to display the fault analysis data.

[0084] After sending the fault analysis data to the user terminal device, the cloud server also sends an acknowledgement information to the vehicle fault information processing device based on the communication address of the vehicle fault information processing device (which can be integrated into the two-dimensional code), telling the vehicle fault information processing device that the data has been sent, and then controlling the user terminal to display the fault analysis data.

[0085] The vehicle fault information processing device can send a control command to the user terminal device through a network communication protocol, requiring it to display the fault analysis data. This command can contain instructions on how to display the data, such as the content, format, position, rendering method, etc. of the data to be displayed.

[0086] For the user terminal, it needs to have a module to receive and analyze the control command. When receiving the control command sent by the vehicle fault information processing device, this module will display the fault analysis data to the user according to the instructions in the command.

[0087] Specifically, referring to FIG. 4, FIG. 4 is a specific embodiment diagram of step 106 of the vehicle fault information processing method in the embodiment of the present application, which includes the following specific implementation:

[0088] 1061、Detecting that the user terminal receives the fault analysis data, controlling the user terminal to perform rendering operation on the fault analysis data to obtain a fault analysis report;

[0089] Specifically, the user terminal device receives the fault analysis data sent by the cloud server through the network, which can be JSON, XML or other format data. The triggered event will call a preset rendering function, including but not limited to using HTML, CSS, JavaScript, etc. The generated fault analysis report will be sent to the display module of the user terminal device, and the display module will display the report to the user. The display module can be a browser.

[0090] Optionally, when the user terminal receives the fault analysis data, the browser in the user terminal is controlled to perform rendering operation on the fault analysis data to obtain a fault analysis report. Wherein, after the network module of the user terminal device receives the fault analysis data sent by the cloud server, an event is triggered. The event is captured by the browser on the user terminal device, and the browser performs rendering operation on the received fault analysis data according to a preset event processing function. After the rendering operation is completed, a fault analysis report is obtained. The report can be an HTML page for displaying in the browser.

[0091] In the process, the vehicle fault information processing device sends control instructions to the user terminal device through the network. These instructions can be "start receiving data", "start rendering data", "display report" and the like. The user terminal device is provided with a module to receive and analyze these instructions and perform corresponding operations according to the instructions.

[0092] 1062、Control the user terminal to display the fault analysis report.

[0093] In steps 1061-1062, by performing rendering operation on the fault analysis data, the originally complex data can be converted into an easily understandable report, so that the user can more easily understand the fault condition and help to handle the fault.

[0094] In the embodiment of the application, when the vehicle fault information processing device detects the fault code, it acquires the freeze frame data corresponding to the fault code and generates a two-dimensional code. When the user terminal scans the two-dimensional code, it sends a request for obtaining control authority. After obtaining the control authority, it controls the user terminal to send a fault analysis request to the cloud, and after the cloud feeds back the fault analysis data to the user terminal, it controls the user terminal to display the data. In this method, the built-in storage space of the vehicle fault information processing device only needs to temporarily save some fault codes, freeze frame data and generated two-dimensional codes, and does not need to save a large amount of fault information for a long time, so that the problem of insufficient storage space of the vehicle fault information processing device is effectively solved, and the problem of integrating a printer into the vehicle fault information processing device is avoided, thus the convenience of the vehicle fault information processing device in handling fault analysis business is improved.
