[0025] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary 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 limited by the embodiments set forth herein.

[0026] At present, the field of vehicle maintenance faces two major challenges: First, when maintenance technicians diagnose vehicle abnormalities, although they can obtain the data stream of the vehicle's electronic components, due to the lack of a benchmark reference value to determine whether the data stream is abnormal, it is difficult to accurately identify whether the vehicle has a fault; second, when multiple technicians are required to collaboratively diagnose the abnormality of the same vehicle, there is a lack of an effective vehicle information sharing mechanism, and information cannot be shared for collaborative analysis. These problems not only reduce the efficiency and accuracy of fault diagnosis, but also increase the complexity and cost of maintenance. Therefore, a vehicle information sharing method is urgently needed to solve the above problems and improve the efficiency and quality of vehicle maintenance.

[0027] Figure 1 FIG. 2 shows a flow chart of a first vehicle information sharing system provided by an embodiment of the present application. Figure 1 As shown, the first vehicle information sharing system 10 includes a first vehicle diagnostic device 11 and a second vehicle diagnostic device 12. The first vehicle diagnostic device 11 and the second vehicle diagnostic device 12 are used to perform relevant steps in the vehicle information sharing method provided in the present application.

[0028] The first vehicle diagnostic device 11 and the second vehicle diagnostic device 12 are electronic devices. The structure of the electronic devices such as the first vehicle diagnostic device 11 or the second vehicle diagnostic device 12 is described below. Figure 2 A schematic diagram of the structure of an electronic device provided in an embodiment of the present application is shown, and the specific embodiment of the present application does not limit the specific implementation of the electronic device.

[0029] like Figure 2 As shown, the electronic device 20 may include a processor 22 and a memory 24 .

[0030] The memory 24 is used to store a computer program 26. The memory 24 may include a high-speed RAM memory, or may also include a non-volatile memory, such as at least one disk memory. The computer program 26 may include computer executable instructions.

[0031] The processor 22 is used to execute the computer program 26 to implement the vehicle information sharing method provided in the embodiment of the present application.

[0032] The processor 22 may be a central processing unit (CPU), or an application-specific integrated circuit (ASIC), or one or more integrated circuits configured to implement the embodiments of the present application. The one or more processors included in the electronic device 20 may be processors of the same type, such as one or more CPUs; or may be processors of different types, such as one or more CPUs and one or more ASICs.

[0033] Figure 3 The flowchart of the vehicle information sharing method provided by the present application is shown in FIG. Figure 3 As shown, the method comprises the following steps:

[0034] Step 110: The first vehicle diagnostic device 11 obtains attribute information of the first vehicle.

[0035] Among them, the vehicle attribute information includes the vehicle's brand, model and year.

[0036] Step 120 : The first vehicle diagnostic device 11 collects data of electronic components in the first vehicle to obtain a data stream.

[0037] In order to determine whether the vehicle is abnormal, a normal value range is usually set for the data of the electronic components, that is, the state value range when the vehicle is running normally, and the normal value range is fixed. In some cases, even if the real-time data of the electronic components does not exceed the normal value range but is close to the minimum or maximum value of the range, it will have an impact on the normal operation of the vehicle. At this time, the normal value range of the electronic component data is not enough to provide a reference for the maintenance technician, making it difficult for the maintenance technician to find potential faults in the vehicle. For example, the throttle angle, its normal value range is generally 2°-6°, but when it reaches around 3° during actual use of the vehicle, it will affect the normal operation of the vehicle, such as: idle jitter, automatic transmission shift shock, increased fuel consumption, etc. Therefore, if the normal value range is set unreasonably, it is impossible to determine that the vehicle may have an abnormal situation.

[0038] After the maintenance technician reads the data stream of the operating status of the vehicle to be tested through the vehicle diagnostic equipment, when the data stream of the vehicle to be tested cannot locate the fault, if there is a lack of sample data for reference, and the key values ​​of the data stream of the vehicle to be tested cannot be compared with those of other normal vehicles, it may be impossible to find that the data stream of the vehicle to be tested is within the normal reference value range but has exceeded the range of normal vehicle operating status values, thereby making it impossible to locate the fault of the vehicle to be tested.

[0039] Therefore, in an embodiment of the present application, data of the electronic component of the first vehicle can be collected when the electronic component is in a normal state to obtain a data stream, and then a benchmark reference value can be subsequently determined based on the data stream, so that when locating the abnormality of the electronic component of other vehicles with the same attribute information as the first vehicle, it can be determined based on the benchmark reference value whether an abnormality has occurred in the detected vehicle, or whether the data of the electronic component of the detected vehicle is within the normal reference value range but deviates greatly from the benchmark reference value, thereby determining whether the detected vehicle has potential faults for risk investigation.

[0040] It is understandable that when a vehicle is in an abnormal state, the specific abnormality of the vehicle can be located through the data of the electronic component. Therefore, in the embodiment of the present application, when the vehicle is in an abnormal state, in order to locate the specific abnormality of the vehicle, the data of the electronic component of the first vehicle can be collected when the electronic component of the first vehicle is in an abnormal state to obtain a data stream, so as to subsequently determine the specific abnormality of the first vehicle according to the data stream.

[0041] Specifically, after the first vehicle diagnostic device 11 is connected to the On-Board Diagnostics (OBD) port of the first vehicle, the first vehicle diagnostic device 11 can collect data of electronic components in the first vehicle. The data stream can be obtained by continuously collecting data of the electronic components at multiple times until a request to stop collecting data is received or the number of times of collecting data reaches a threshold number, wherein the threshold number can be set as needed, such as 90, 99 or 110.

[0042] Step 130 : The first vehicle diagnostic device 11 determines a first reference value according to the data stream.

[0043] The first reference value may be determined as needed. For example, a representative value may be determined based on the data stream, and the representative value may be used as the first reference value. For example, the maximum value, minimum value and / or average value of the data stream may be determined, and the determined maximum value, minimum value and / or average value may be used as the first reference value accordingly. It is worth noting that the first reference value may be a single value or multiple values, and the number of data included in the first reference value is not limited here.

[0044] Even if the vehicles with different attribute information include electronic components with the same name, their specific configurations and performances may be different. Therefore, in this step, the attribute information of the first vehicle is obtained so that the data flow of its electronic components can be accurately analyzed and judged whether it is normal according to the characteristics of the first vehicle.

[0045] Step 140: The first vehicle diagnostic device 11 establishes a correspondence between the first reference value and the attribute information of the first vehicle.

[0046] It can be understood that even if vehicles with different attribute information include electronic components with the same name, their specific configurations and performances may be different. Therefore, in the embodiment of the present application, by establishing a correspondence between the first reference value and the attribute information of the first vehicle, if the first reference value is a reference value determined based on the data stream collected when the electronic component is in a normal state, then when diagnosing the same electronic component of other vehicles with the same attribute information as the first vehicle, the first reference value can be determined based on the correspondence and used as a reference value for diagnosing whether the electronic component of the detected vehicle is abnormal; if the first reference value is a reference value determined based on the data stream collected when the electronic component is in an abnormal state, then the correspondence can be shared with other technicians to jointly diagnose the abnormality of the first vehicle.

[0047] Step 150 : the first vehicle diagnostic device 11 sends the first reference value, the attribute information of the first vehicle, and the corresponding relationship to the second vehicle diagnostic device 12 .

[0048] The first vehicle diagnostic device 11 may send the first reference value, the attribute information of the first vehicle and the corresponding relationship to the second vehicle diagnostic device 12 via SMS, email or the like.

[0049] Step 160 : the second vehicle diagnostic device 12 receives the first reference value, the attribute information of the first vehicle, and the corresponding relationship sent by the first vehicle diagnostic device 11 .

[0050] Among them, if the data stream collected in step 120 is when the electronic components of the first vehicle are in a normal state, the second vehicle diagnostic device 12 may be a device that needs to diagnose the vehicle to be diagnosed, and the attribute information of the vehicle to be diagnosed is the same as that of the first vehicle. Therefore, after the second vehicle diagnostic device 12 receives the first reference value, the attribute information and the corresponding relationship, it can determine the first reference value that is the same as the attribute information of the vehicle to be diagnosed according to the corresponding relationship, and use the first reference value as the benchmark reference value to diagnose whether the vehicle to be diagnosed has an abnormality.

[0051] If the data stream collected in step 120 is when the electronic components of the first vehicle are in an abnormal state, the second vehicle diagnostic device 12 may be a device used by other maintenance technicians. Therefore, after the second vehicle diagnostic device 12 receives the first reference value, the attribute information of the first vehicle, and the correspondence between the two, it can determine the first reference value and the attribute information of the first vehicle based on the correspondence, thereby realizing collaborative diagnosis of the first vehicle.

[0052] In an embodiment of the present application, when an electronic component of the first vehicle is in an abnormal state, the first vehicle diagnostic device 11 collects the data stream of the electronic component and obtains the attribute information of the first vehicle, and then determines a first reference value based on the data stream, and sends the first reference value and the attribute information of the first vehicle and the corresponding relationship between the two to the second vehicle diagnostic device 12, so that a user of the second vehicle diagnostic device 12 can collaboratively diagnose the abnormality of the first vehicle based on the first reference value and the attribute information of the first vehicle, thereby improving the efficiency of abnormal diagnosis of the first vehicle.

[0053] When the electronic component of the first vehicle is in a normal state, the first vehicle diagnostic device 11 collects the data stream of the electronic component and obtains the attribute information of the first vehicle, and then determines a first reference value according to the data stream, and sends the first reference value and the attribute information of the first vehicle and the correspondence between the two to the second vehicle diagnostic device 12, so that the second vehicle diagnostic device 12 can use the first reference value as a benchmark reference value when diagnosing an abnormality for the same electronic component of other vehicles with the same attribute information as the first vehicle, thereby improving the accuracy of abnormality diagnosis.

[0054] In some embodiments, step 150 may also be that the first vehicle diagnostic device 11 sends the first reference value, attribute information and the corresponding relationship to the server. Correspondingly, step 160 is that the server receives the first reference value, attribute information of the first vehicle and the corresponding relationship sent by the first vehicle diagnostic device 11, and stores the received first reference value, attribute information of the first vehicle and the corresponding relationship between the two.

[0055] In some embodiments, the second vehicle diagnostic device 12 is determined by the first vehicle diagnostic device 11 from multiple devices. Specifically, the first vehicle diagnostic device 11 determines an interactive device with which the first vehicle diagnostic device 11 has previously transmitted data, and determines the interactive device as the second vehicle diagnostic device 12.

[0056] In the embodiment of the present application, since data transmission has occurred between the first vehicle diagnostic device 11 and the interactive device at a historical moment, it is indicated that the interactive device is a trusted device. Therefore, by determining the interactive device as the second vehicle diagnostic device 12, the problem of data leakage caused by the first vehicle diagnostic device 11 sending data to an untrusted device can be avoided.

[0057] In some embodiments, if the first vehicle diagnostic device 11 receives a data request sent by a requesting device, the first vehicle diagnostic device 11 determines the requesting device as the second vehicle diagnostic device 12. The data request is used to request the first vehicle diagnostic device 11 to send a reference value to the requesting device.

[0058] In the embodiment of the present application, after receiving the data request sent by the requesting device, the first vehicle diagnostic device 11 determines the requesting device as the second vehicle diagnostic device 12, and then the first vehicle diagnostic device 11 subsequently sends the first reference value, the attribute information of the first vehicle and the correspondence between the two to the second vehicle diagnostic device 12, so that the second vehicle diagnostic device 12 can use the first reference value.

[0059] In other embodiments, the first vehicle diagnostic device 11 determines the second vehicle diagnostic device 12 from the multiple devices in the following manner: the first vehicle diagnostic device 11 obtains multiple pieces of historical attribute information corresponding to the multiple devices, determines target historical attribute information including the attribute information of the first vehicle from the multiple pieces of historical attribute information, and determines the device corresponding to the target historical attribute information as the receiving device. Each piece of historical attribute information is historical attribute information of a vehicle whose data stream has been collected by the device corresponding to each piece of historical attribute information at a historical moment.

[0060] If a vehicle diagnostic device has collected data streams from a vehicle at a historical moment, it means that the vehicle diagnostic device has performed an abnormal diagnosis on the vehicle at a historical moment. Therefore, in the embodiment of the present application, the first vehicle diagnostic device 11 obtains attribute information of vehicles diagnosed by multiple devices at historical moments (i.e., historical attribute information). If the historical attribute information of a vehicle diagnostic device includes the attribute information of the first vehicle, it means that the vehicle diagnostic device has diagnosed a vehicle with the same attribute information as the first vehicle at a historical moment.

[0061] For a vehicle diagnostic device that has detected other vehicles with the same attribute information as the first vehicle at a historical moment, it may subsequently detect other vehicles with the same attribute information as the first vehicle. Therefore, in the implementation of the present application, by determining the device as the second vehicle diagnostic device 12, if the first reference value is a reference value determined based on a data stream collected when the electronic component is in a normal state, the first vehicle diagnostic device 11 sends the first reference value, the attribute information of the first vehicle, and the correspondence between the two to the second vehicle diagnostic device 12, so that the second vehicle diagnostic device 12 can subsequently determine the abnormality of the diagnosed vehicle based on the first reference value when diagnosing other vehicles with the same attribute information as the first vehicle. Or for a vehicle diagnostic device that has detected other vehicles with the same attribute information as the first vehicle at a historical moment, and has diagnostic experience in analyzing and diagnosing abnormalities of vehicles with such attribute information, by determining the device as the second vehicle diagnostic device 12, if the first reference value is a reference value determined based on a data stream collected when the electronic component is in an abnormal state, the first vehicle diagnostic device 11 sends the first reference value, the attribute information of the first vehicle, and the correspondence between the two to the second vehicle diagnostic device 12, so that the second vehicle diagnostic device 12 can diagnose the abnormality for the first vehicle based on its historical diagnostic experience, thereby improving the efficiency of diagnosing the abnormality for the first vehicle.

[0062] exist Figure 3 Based on the embodiment of the vehicle information sharing method provided, in the embodiment of the present application, the method further includes the following steps:

[0063] Step a1: The first vehicle diagnostic device 11 receives the second reference value sent by the sending device.

[0064] The second reference value is a reference value determined based on the data stream of the electronic component of the second vehicle, and the second vehicle and the first vehicle are the same vehicle or the property information of the two vehicles is the same. The sending device can be a vehicle diagnostic device, a server or other electronic device.

[0065] Step a2: the first vehicle diagnostic device 11 updates the first reference value in the corresponding relationship to the second reference value to obtain an updated corresponding relationship.

[0066] Step a3: the first vehicle diagnostic device 11 sends the second reference value, the attribute information of the first vehicle and the updated corresponding relationship to the second vehicle diagnostic device 12 .

[0067] In the embodiment of the present application, when the user determines the second reference value by using the data stream of the electronic component acquired the most recently, the second reference value is more timely than the first reference value, or when the user updates the reference value determination method and determines the second reference value with higher accuracy based on the data stream, the second reference value is more valuable than the first reference value. Therefore, the first vehicle diagnostic device 11 receives the second reference value and updates the first reference value in the corresponding relationship to the second reference value, and then sends the second reference value, the attribute information of the first vehicle and the corresponding relationship between the two to the second vehicle diagnostic device 12, so as to synchronously update the reference value stored in the second vehicle diagnostic device 12, thereby improving the accuracy of the reference value used subsequently.

[0068] In some embodiments, in order to improve the security of the first reference value, the attribute information of the first vehicle, and the correspondence between the first vehicle diagnostic device 11 and the second vehicle diagnostic device 12, the first vehicle diagnostic device 11 generates a graphic code carrying the first reference value, the attribute information, and the correspondence, and sends the graphic code to the second vehicle diagnostic device 12. After receiving the graphic code, the second vehicle diagnostic device 12 can obtain the first reference value, the attribute information, and the correspondence by decoding the graphic code. The first vehicle diagnostic device 11 improves the security of the sent data by sending the graphic code to the second vehicle diagnostic device 12 instead of directly sending the first reference value, the attribute information of the first vehicle, and the correspondence. In addition, the first vehicle diagnostic device 11 can also display the graphic code on its display screen, and the second vehicle diagnostic device 12 can obtain the first reference value, the attribute information, and the correspondence by scanning the graphic code and decoding the graphic code.

[0069] Figure 4 FIG. 2 shows a schematic diagram of a second vehicle information sharing system provided by an embodiment of the present application. Figure 4 As shown, the second vehicle information sharing system 30 includes a third vehicle diagnostic device 31, a server 32 and a fourth vehicle diagnostic device 33. The third vehicle diagnostic device 31 and the fourth vehicle diagnostic device 33 are similar to the electronic device 20, so the structures of the third vehicle diagnostic device 31 and the fourth vehicle diagnostic device 33 are not described in detail here.

[0070] Figure 5 FIG. 2 shows a flow chart of a vehicle information sharing method provided by another embodiment of the present application. Figure 5 As shown, the method comprises the following steps:

[0071] Step 210: The third vehicle diagnostic device 31 obtains attribute information of the first vehicle.

[0072] Step 220 : The third vehicle diagnostic device 31 collects data of electronic components in the first vehicle to obtain a data stream.

[0073] Step 230 : The third vehicle diagnostic device 31 determines a first reference value according to the data stream.

[0074] Step 240: The third vehicle diagnostic device 31 establishes a correspondence between the first reference value and the attribute information of the first vehicle.

[0075] Step 250 : the third vehicle diagnostic device 31 sends the first reference value, the attribute information of the first vehicle and the corresponding relationship to the server 32 .

[0076] Step 260 : The server 32 receives the first reference value, the attribute information of the first vehicle, and the corresponding relationship sent by the third vehicle diagnostic device 31 .

[0077] The server 32 receives and stores the first reference value, the attribute information of the first vehicle, and the corresponding relationship between the two.

[0078] Step 270 : The server 32 sends the first reference value, the attribute information of the first vehicle, and the corresponding relationship to the fourth vehicle diagnostic device 33 .

[0079] Step 280 : The fourth vehicle diagnostic device 33 receives the first reference value, the attribute information of the first vehicle, and the corresponding relationship sent by the server 32 .

[0080] Among them, the embodiments of the present application and Figure 3 The embodiments provided are similar, so the principles and implementation methods of the embodiments of this application can be referred to Figure 3 The embodiments provided will not be described in detail here.

[0081] In some embodiments, when the electronic device 20 executes the vehicle information sharing method provided by the present application, when executing the data reading function, the minimum and maximum values ​​of the refreshed values ​​of each numerical type data item are calculated in real time and displayed in the data stream list in the real interface. If the current vehicle model supports displaying reference values, a switch button for the minimum and maximum values ​​is displayed at the top of the data stream list in the display interface. The display interface of the electronic device 20 displays the reference value range of the data item by default, otherwise it will not be displayed. The user clicks the switch button on the right side of the reference value, and the electronic device 20 can display the minimum and maximum values ​​of each data item that has been calculated. Among them, only the minimum and maximum values ​​are displayed for the data items of numerical type, and there are no minimum and maximum values ​​for the text type and enumeration type.

[0082] After connecting the vehicle to be diagnosed using the electronic device 20 (e.g., vehicle diagnostic equipment), enter the vehicle series software corresponding to the vehicle model, and view the ECU information and data stream information of the vehicle to be diagnosed in the vehicle series software. When viewing the data stream information, the data stream reference value sampling function in the electronic device 20 can be used. When the user clicks the reference value sampling button, he can choose whether to sample and record all data items of the current ECU or only sample the selected data items. After the user chooses to sample all or sample the selected items, the management program of the electronic device 20 notifies the vehicle series software that it has started sampling and recording data stream items by calling the middleware interface. After the vehicle series software is called, it starts to refresh the data stream items.

[0083] If you select "sample all", the vehicle software will refresh all the data in the entire data stream list; if you select "sample only the selected data stream items", the vehicle software will only refresh the data of the selected data stream items. The management program of the electronic device 20 will first reset the calculated minimum and maximum records. The vehicle software will refresh from the first item to the last item as one effective cycle. Each time a data item is refreshed, the single cycle progress will increase by 1 until all data items that need to be refreshed are completed. After refreshing a cycle, the next cycle will continue. In a single cycle, the user is updated with the current sampling progress based on the number of refreshed data, and the number of completed cycles will be displayed at the same time.

[0084] During the data stream sampling and recording process, the user can choose to stop sampling at any time. If the user does not perform any operation during the sampling process, a maximum of 99 valid sampling cycles will be completed, and the management program will automatically stop sampling and recording, and notify the vehicle software of the end of sampling by calling the middleware interface. After being notified to stop sampling, the vehicle software will be restored to the state before sampling, and only the data items visible on the current screen and the selected data items will be refreshed. After stopping sampling, the management program will no longer sample and record the refreshed values ​​of the data stream items, and save the sampled data to the local database, marking it as temporarily saved.

[0085] During the sampling and recording process of the data stream, the management program calculates in real time the minimum, maximum and average reference values ​​of each numerical type data stream item being recorded, as well as the real-time refreshed values ​​themselves. The above sampled and recorded values ​​include but are not limited to metric values, imperial values ​​and American values, as well as units under the corresponding unit systems.

[0086] After completing the sampling of the reference value, enter the reference value editing. The user can choose whether to edit the minimum, maximum, and average values ​​of the data stream items of all sampling records, and can manually complete the modification of the sampling data. The value after editing the value must meet the basic conditions that the minimum value is less than the maximum value and the average value, the average value is greater than the minimum value and less than the maximum value, and the maximum value is greater than the minimum value and the average value. Values ​​that do not meet the above conditions are prompted in the form of a red input box to indicate that the value entered by the user is illegal. If the edited reference value sampling result contains illegal values, the user is reminded that there are illegal values ​​and cannot be saved and submitted. Click Reset to restore the data of the entire list to the state before editing and modification. After all the input content is legal, click Finish to update and save the edited data to the local database. After saving successfully, enter the next page to create filter conditions.

[0087] When the sampled data is saved to the database, a unique string file number consisting of 20 random digits is generated. The file number generated by each sampled data is unique and cannot be repeated. The file number, vehicle data, control unit information, etc. are displayed on the creation filter condition page. Users can select filter conditions according to the current diagnostic vehicle status. The optional vehicle status includes system fault status, engine status, coolant temperature, ambient temperature, electrical load status, air conditioning status, vehicle speed, driving status, gear lever position, fuel status, power battery SOC status, power meter status, vehicle load, driving mode status, altitude, weather, etc. The filter conditions can also be added, deleted, edited, etc. on the server management console. All vehicle status filter conditions are optional first-level filter conditions. There are second-level filter items under each first-level filter condition. Click the first-level option, and the pop-up window will display the second-level filter conditions under it. Users can cancel or select single or multiple filter conditions to add filter conditions for the sampled data to facilitate query and filtering in the cloud reference value list. Users can enter the remarks in the remarks edit box.

[0088] The user clicks the Save Local button, and the management program saves all the selected filter conditions and sampling data to the local database and marks them as saved. After saving, the filter condition creation page is closed and the data flow page is returned. The user can click the Save and Cloud Backup button or the Save Local button. The management program saves all the selected filter conditions and sampling data to the local database and marks them as saved. After saving, the user can close the filter condition creation page and return to the data flow page. After the above process is completed, the sampling data is simultaneously triggered to be uploaded to the cloud server.

[0089] When the task of uploading the sampled data to the cloud server is triggered, all the sampled data saved in the above are queried from the local database according to the file number of the data to be uploaded, and a json file named with the file number of the sampled data is generated. After the json file is successfully generated, this json file is uploaded to the server through the file upload interface provided by the cloud service. After the file is successfully uploaded, the cloud service interface returns the uploaded file download address and file id to the management program. After the management program successfully receives the information after the upload is successful, it saves the file download address and file id to the local database and triggers the sampled data reporting task. In the reporting task, the management program transmits the sampling data information such as vehicle data, control unit information, vehicle status selected filtering conditions, remarks, file download address and file id to the cloud service. After the cloud service returns the report success, the management program marks this sampled data as successfully uploaded and downloaded in the local database.

[0090] The user can click on the reference value on the data stream page to enter the reference value page. On the reference value page, you can view all the sampled data that are consistent with the current model and system saved in the local database, including data saved locally and shared with other users. The user can choose to view all data, only view the data saved locally, or only view the data shared by others. Local storage refers to the sampled data saved in the device by the user through the sampling of the data stream on the current diagnostic device. The sampling process is described above. Sharing by others means that by clicking the Get Share button, you can download and save the sampled data shared by other users. In the locally saved data of the reference value list, the data that has been successfully uploaded to the cloud server is marked with a cloud icon, and the data shared by other users is marked with others. Click the drop-down triangle area such as brand, model, system fault status, etc., and the electronic device 20 pops up a window to display the secondary options of the corresponding category to quickly filter the sampled data to be found. The user can click on any row in the displayed reference value list to select the row, click the selected row again to cancel the selection, select any row and click the OK button to import the selected sampled data into the data stream page, and the minimum, maximum and average values ​​of the called sampled data will be displayed on the data stream page. If the data stream page has called the oversampled data, and no row is selected in the reference value list, just click the OK Return button, and the data stream page will return to the state before the call, and only the minimum and maximum values ​​of the current data stream will be displayed.

[0091] The user clicks the Get Share button on the reference value page to enter the Add Reference Value Data page, where the file number of the sampling data shared by other users can be manually entered, or the file number can be automatically obtained by scanning the QR code of the sampling data shared by other users by clicking the Scan button. After entering the file number, click the OK button to submit the file number to the cloud server to query the sampling data information corresponding to the file number. If the sampling corresponding to the file number still exists and is valid on the cloud server, the cloud service returns all the information of the sampling data, including the download link of the json file mentioned above. After the electronic device 20 obtains the download link of the json file, it downloads the corresponding json file from the cloud server to the local computer. After the download is successful, the data of all sampling data items contained in the json file is parsed out, and saved to the local database together with all the information of the sampling data, and marked as downloaded and saved. The sampling data that is successfully downloaded and saved through the Get Share function can be viewed in the reference value list and the local reference value list.

[0092] The user clicks the reference value button, and after selecting the sampled data as above, the call is confirmed. Returning to the data stream page, the sampled data that has been called and imported can be viewed. The minimum, maximum, and average values ​​of the sampled data that have been called are displayed in the data stream list. The data can be displayed in four styles: text style, curve chart style, bar chart style, and instrument panel style. When the electronic device 20 just imports the sampled data, it is preferred to switch the entire data stream list to a bar chart style display. There is a button at the top of the data stream list to quickly switch between the numerical value and the bar chart style. In the bar chart style and instrument panel style, the blue lower triangle points to the minimum value, the black lower triangle points to the average value, and the red upper triangle points to the maximum value. The blue progress bar indicates the area where the current value is located, and the position of the current value corresponding to the minimum, maximum, and average value can be intuitively observed. By displaying data graphically, it can help maintenance technicians find abnormal data faster and more conveniently to locate fault problems. In the curve chart style, the light blue dotted line segment indicates the position trend of the minimum value, the black dotted line segment indicates the position trend of the average value, the red dotted line segment indicates the position trend of the maximum value, and the blue implementation indicates the real-time value position trend. When the current value exceeds the minimum and maximum ranges of the sampled data, the vehicle may have a fault.

[0093] The user clicks the sort button at the top of the data stream list to select the sorting method of the data stream list. You can choose to sort by data stream value in ascending order, descending order, unit order, and descending order of abnormal range index. When the data stream value is selected in ascending order, the electronic device 20 arranges the real-time values ​​in the current data stream list in ascending order, and the data items of digital type are prioritized, and the non-digital type is ranked last, where the data items of digital type are sorted from small to large according to the size of the value. When the data stream value is selected in descending order, the electronic device 20 arranges the real-time values ​​in the current data stream list in descending order, and the data items of digital type are prioritized, and the non-digital type is ranked last, where the data items of digital type are sorted from large to small according to the size of the value. When the data stream unit is selected, the electronic device 20 preferentially displays the data items with units, and the data items without units are placed at the back. When the abnormal range index is selected, the electronic device 20 calculates the deviation value of the current real-time value to the minimum and maximum values. The larger the deviation value, the priority is arranged, which helps the maintenance technician quickly find the data with large differences from the normal sampled data. The user clicks the reset button, and the electronic device 20 returns to displaying the data stream in the default sorting method.

[0094] On the reference value preview page, users can view the local reference value and cloud backup reference value list. In the local reference value list, you can view the sampled data saved by the user for all vehicle models after sampling on this device, as well as the sampled data shared by other users for sharing and downloading. If the user samples the sampled data that has been saved but not uploaded to the server on the electronic device 20, the "Upload Cloud Backup" button will be displayed. If the saved data has been uploaded to the server, the share button will be displayed. The electronic device 20 displays the mark shared by others by obtaining the sampled data downloaded for sharing. This type of data cannot be shared with other users by the current user through the sharing function. The user clicks the Upload Cloud Backup button to trigger the process of uploading the sampled data to the cloud server. After the upload is successful, the Upload Cloud Backup button of the sampled data in the local reference value list is hidden, and the share button is displayed. The user samples and saves the data himself, and the upload service has been successful. By clicking the share button, the electronic device 20 can send the sharing information to other users through SMS or email. Other users receive the shared SMS or email and can obtain the vehicle information, file number, QR code link containing file number information, etc. of the user's shared sampled data. The user clicks the Add button at the top of the reference value preview page, and the electronic device 20 enters the page for obtaining the sharing function. Then, through the “Obtain Sharing” function, the shared sampling data can be downloaded and saved to the electronic device 20 .

[0095] The user clicks the search button at the top of the reference value preview page and can enter keywords to search the current list. The user clicks the filter button and a pop-up window appears to select brand, model, year, engine, and system to quickly filter the required sampled data. The user clicks the edit button and the electronic device 20 enters the edit mode. The user clicks to select the sampled data to be deleted and clicks the delete button to delete the selected item or delete all data on the current page.

[0096] The user clicks the Compare button and can select any two sample data for comparison. The minimum, maximum, and average values ​​of all data items of the two sample data can be compared. The same data items with different values ​​in the two sample data are marked with red arrows. The larger average value is displayed with a red up arrow, and the smaller average value is displayed with a red down arrow.

[0097] The user clicks the cloud backup button and selects to view the cloud backup reference value list to view all the sampling data uploaded to the cloud server by the current user. In this list, the user can view the file number, vehicle information, control unit information, vehicle status information, etc. corresponding to the sampling data. For details of all information sources, please refer to the above introduction.

[0098] The user can click the add button, search button, filter button, and edit button at the top of the cloud backup list. The functions of these buttons are similar to those of the buttons at the top of the local reference value. The difference is that the data of the cloud backup list comes from the cloud server, and the electronic device 20 needs to obtain it from the cloud service when connected to the Internet. Adding, searching, filtering, and deleting all require requesting the cloud server interface. If you choose to delete the cloud reference value data, the reference value data on the cloud service will be deleted and cannot be restored.

[0099] The download status of each sampled data can be viewed in the cloud backup list. For data that has been saved locally and uploaded to the cloud server, its status is downloaded; for data that has been saved locally and uploaded to the cloud service before, if the locally saved data is deleted later, its status is not downloaded. The user can download by clicking the download icon. After the download starts, the electronic device 20 displays the downloading status, and the operation column displays a cancel download button. During the download process, the user clicks the cancel download button to cancel the download. If the download fails, the download failure is displayed, and the operation column displays a re-download button. The user clicks the re-download icon to re-download.

[0100] In the embodiment of the present application, by providing a new data reference value sampling and calling function for the electronic device 20, the minimum, maximum, average and other sampling data of each data item of the data stream of the normal vehicle system can be recorded in the process of diagnosing the vehicle by using the electronic device 20, and the sampling data of other vehicles can be viewed and compared in real time while reading the data stream. In addition, the functions of reusable, backupable, restorable and shareable data stream sampling data are added to the electronic device 20, that is, the electronic device 20 can save the data in the device or upload it to the cloud service. This function can be used for cloud backup of sampling data to prevent the loss or accidental deletion of local sampling data of the electronic device 20, and can also be downloaded and restored from the cloud backup, and the cloud backup sampling data can also be shared with users of other diagnostic devices. The sampling data can be used for different diagnostic devices to compare the read data stream of the vehicle, providing a fast and efficient data stream key value comparison function, and at the same time increasing the number of effective reference data samples, which can help maintenance technicians find abnormal data information of the vehicle for diagnosis faster and more accurately, and improve maintenance accuracy and maintenance efficiency.
