[0040] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0041] like Figure 1 As shown, this utility model provides a fault information conversion and extraction device, comprising:

[0042] Fault diagnosis module 1 is used to diagnose vehicle faults and generate diagnostic messages;

[0043] Upload Decision Module 2: Connected to Fault Diagnosis Module 1, used to send diagnostic messages;

[0044] Fault Information Conversion Module 3: Connected to Upload Decision Module 2, it is used to convert the diagnostic messages sent by Upload Decision Module 2 into application messages and send the application messages;

[0045] Vehicle bus 4: Connected to fault information conversion module 3, used to transmit application messages sent by fault information conversion module 3;

[0046] The vehicle terminal 5 is connected to the vehicle bus 4 and is used to extract application messages from the vehicle bus 4 and send application messages to the cloud server 7.

[0047] In specific implementation, such as Figure 2 As shown, after the fault diagnosis module 1 detects a serious fault or a fault that occurs frequently, the upload decision module 2 determines whether an upload is necessary. If an upload is required, the fault information conversion module 3 converts the diagnostic message of the fault information into an application message and transmits it to the vehicle terminal 5 via the vehicle bus 4. The vehicle terminal 5, acting as the uploader of fault data, extracts data from the vehicle bus 4 and uploads it to the cloud server 7 via the network channel. The cloud server 7 receives the data, parses it in real time, and pushes it to different types of application terminals for data display or fault alerts. Simultaneously, the data is stored in cloud storage devices to meet future big data analysis needs. The fault information conversion module 3 converts the diagnostic message of the fault information into an application message, effectively uploading fault information while significantly reducing data upload traffic and avoiding network congestion. The upload decision module 2 enables real-time uploading of fault data and real-time fault notification, resolving concerns for users and OEMs. This fault information conversion and extraction device can process and convert pre-collected vehicle data, transforming diagnostic messages into application messages, ensuring data validity, saving traffic, facilitating cloud data analysis and rapid response, and reducing additional computation by functional controllers or the cloud.

[0059] Specifically, encrypted application messages are cached in the queue of the first cache unit 56 and uploaded periodically, avoiding the waste of bandwidth caused by high-frequency uploads. If a transmission fails, the message will be stored in a designated area for a certain period of time to ensure that the data is not lost and to guarantee the integrity of the data.

[0060] Optionally, the vehicle terminal 5 also includes:

[0061] The authentication unit 55 is connected to the communication unit 54 and is used to authenticate with the cloud server 7 through the communication unit 54.

[0069] Optionally, the upload decision module 2 is also used to decide whether to send a diagnostic message based on the fault type and the frequency of fault occurrence.

[0070] Specifically, deciding whether to send diagnostic messages based on the type and frequency of faults can save bandwidth and facilitate cloud data analysis and rapid response.

[0071] This embodiment also provides a car, including the fault information conversion and extraction device of this embodiment.

[0072] Specifically, the vehicle is equipped with a fault information conversion and extraction device, which can process and convert pre-collected vehicle data, transforming diagnostic messages into application messages, ensuring data validity, saving bandwidth, facilitating cloud data analysis and rapid response, and reducing additional computation by functional controllers or the cloud.
