Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a diagnostic log assembly method, device, equipment and medium. Background Art

[0002] At present, with the continuous development of automotive electronics, the number of ECUs (Electronic Control Units) installed in automobiles is increasing and becoming more and more complex, which also brings great challenges to troubleshooting. Diagnostic software usually records the diagnostic data generated during the diagnostic process to form a log, and technicians use the log to locate the problem after the problem occurs. There are currently two common ways to record diagnostic communication logs: 1. Record the communication logs of each diagnostic process, and upload the logs generated by the diagnosis to the server when problems occur. The technicians retrieve the logs through the background to analyze the problems; 2. Set the log recording switch, and do not record logs during normal diagnosis. When problems occur, the user turns on the log switch, executes the diagnostic function again to reproduce the problem, and sends the reproduced logs to the technicians for analysis; Both of the above methods have their disadvantages: 1. Recording a log each time will waste a lot of computer memory, especially when executing ECU flashing, which has high timing requirements. Recording diagnostic data logs may not only affect the normal flashing process and cause the flashing to fail, but the huge amount of data will also cause a serious burden on the computer and server bandwidth; 2. Setting the log switch cannot collect first-hand diagnostic data in a timely manner. It often requires a second or Nth reproduction to record successfully. It is not smart enough, which affects the collection of communication logs and the troubleshooting of problems.

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] At present, with the continuous development of automotive electronics, the number of ECUs installed in automobiles is increasing and becoming more and more complex, which also brings great challenges to troubleshooting. Diagnostic software usually records the diagnostic data generated during the diagnostic process to form a log, and technicians use the log to locate the problem after the problem occurs. There are currently two common ways to record diagnostic communication logs: 1. Record the communication logs of each diagnostic process, and upload the logs generated by the diagnosis to the server when problems occur. The technicians retrieve the logs through the background to analyze the problems; 2. Set the log recording switch, and do not record logs during normal diagnosis. When problems occur, the user turns on the log switch, executes the diagnostic function again to reproduce the problem, and sends the reproduced logs to the technicians for analysis; Both of the above methods have their disadvantages: 1. Recording a log each time will waste a lot of computer memory, especially when executing ECU flashing, which has high timing requirements. Recording diagnostic data logs may not only affect the normal flashing process and cause the flashing to fail, but the huge amount of data will also cause a serious burden on the computer and server bandwidth; 2. Setting the log switch cannot collect first-hand diagnostic data in a timely manner. It often requires a second or Nth reproduction to record successfully. It is not smart enough, which affects the collection of communication logs and the troubleshooting of problems.

[0050] To this end, an embodiment of the present application proposes a diagnostic log assembly solution that can store diagnostic logs to improve storage efficiency and reduce bandwidth burden.

[0051] The present application embodiment discloses a diagnostic log assembly method, see Figure 1 As shown, the method includes:

[0052] Step S11: determining an electronic control unit to be diagnosed in the vehicle to be diagnosed based on the diagnostic test information, diagnosing the electronic control unit to be diagnosed and storing diagnostic data generated during the diagnostic process in a first storage area.

[0053] In this embodiment, see Figure 2 As shown, it is a schematic diagram of a diagnostic log assembly method; in the figure, the diagnostic software first requests the maximum length of the diagnostic log and the diagnostic interruption condition that triggers the upload log from the server, and then the server sends the maximum length of the diagnostic log and the diagnostic interruption condition that triggers the upload log to the diagnostic software, and the diagnostic log records the diagnostic log according to the maximum length of the diagnostic log to the diagnostic software, and uploads the diagnostic log to the server when the diagnostic interruption condition that triggers the upload log is triggered, so that the user can view the log and analyze the problem. The specific process of recording the diagnostic log is described in the subsequent content.

[0054] In this embodiment, ECU (electronic control unit) is also called driving computer, on-board computer, etc. Like ordinary computers, ECU is composed of microprocessor, memory, input and output interface, analog-to-digital converter, and large-scale integrated circuits such as shaping and driving.

[0055] It should be pointed out that the diagnostic log DiagnosticLog is divided into two parts: 1-diagnostic test information (including vehicle name, VIN, test system, test function, test time, etc.), 2-diagnostic data.

[0056] In this embodiment, before diagnosing the electronic control unit to be diagnosed and storing the diagnostic data generated during the diagnosis process in the first storage area, it also includes: obtaining a preset maximum log storage size, and setting the first storage area, the second storage area, the third storage area and the fourth storage area based on the maximum log storage size; the maximum log storage size is the sum of the target size and the size of the fourth storage area.

[0057] It should be noted that the OEM technicians can set the maximum size of a single diagnostic log (DiagnoseLogMaxSize) and the diagnostic interruption conditions for uploading diagnostic logs (such as the diagnostic software does not receive a response from the ECU or the ECU responds with a 7F negative response) through the background. For details, see Figure 3 The following is a diagram showing the log size and diagnostic terminal condition settings; see Figure 4 As shown, it is a schematic diagram of memory data; after the diagnostic software is started, it accesses the log setting interface of the background through the network, obtains the size DiagnoseLogMaxSize and the diagnostic interrupt condition Conditions, and applies for 4 arrays in the system memory, ArrayTotalLog (the third storage area) (the size is DiagnoseLogMaxSize to record the final uploaded diagnostic log content), ArrayDiagnosticInfo (the fourth storage area) 0 (the initialization size is M, M is less than DiagnoseLogMaxSize, used to dynamically store diagnostic test information), ArrayDiagnosticData (the first storage area) (the initialization size is N, M+N=DiagnoseLogMaxSize, used to record communication data), ArrayDiagnosticData_Backup (the second storage area) (the initialization size is N, used to store subsequent diagnostic data (communication data) when the data recorded in ArrayDiagnosticData exceeds N).

[0058] In this embodiment, before determining the electronic control unit to be diagnosed in the vehicle to be diagnosed based on the diagnostic test information, it also includes: storing the diagnostic test information in the fourth storage area for subsequent storage in the diagnostic log. It should be noted that after the diagnostic software reads the vehicle information and enters the specific ECU function, the diagnostic test information is recorded in ArrayDiagnosticInfo (the fourth storage area). At this time, the diagnostic software will determine whether it is necessary to interrupt the recording and upload the diagnostic log according to the Conditions sent by the server.

[0059] Step S12: If the diagnosis interruption condition is not triggered until the first storage area is filled up, the diagnosis data generated in the subsequent diagnosis process is stored in the second storage area.

[0060] In this embodiment, if the diagnostic interrupt condition is not triggered until the first storage area is full, the diagnostic data generated in the subsequent diagnostic process is stored in the second storage area, and it also includes: if the diagnostic interrupt condition is triggered when the first storage area is not full, the diagnostic process is interrupted, and the diagnostic data in the first storage area is transferred to the third storage area, and all diagnostic data in the third storage area is uploaded to the server as a diagnostic log.

[0061] Step S13: If the diagnostic interrupt condition is not triggered until the second storage area is filled, the first storage area is cleared, the diagnostic data in the second storage area is transferred to the first storage area, and the second storage area is cleared.

[0062] In this embodiment, if the diagnostic interrupt condition is not triggered until the second storage area is full, before clearing the first storage area, it also includes: if the diagnostic interrupt condition is triggered when the second storage area is not full, the diagnostic process is interrupted, and the second current size of the diagnostic data in the second storage area is determined, and the diagnostic data of the second temporary size in the first storage area is determined in chronological order from back to front; the second temporary size is the difference between the target size and the second current size; the determined diagnostic data of the second current size in the second storage area and the diagnostic data of the second temporary size in the first storage area are transferred to the third storage area.

[0063] Step S14: Jump to the step of storing the diagnostic data generated in the subsequent diagnostic process in the second storage area, and stop the diagnosis when the diagnostic interruption condition is triggered.

[0064] Step S15: transferring the latest diagnostic data of the target size in the first storage area and the second storage area to the third storage area, and uploading the diagnostic data in the third storage area to the server as a diagnostic log.

[0065] In this embodiment, the sizes of the first storage area and the second storage area are the target sizes.

[0066] In this embodiment, the latest diagnostic data of the target size in the first storage area and the second storage area is transferred to the third storage area, including: if the second storage area is empty, the diagnostic data of the target size in the first storage area is transferred to the third storage area; if the second storage area is not empty, the first current size of the diagnostic data in the second storage area is determined, and the diagnostic data of the first temporary size in the first storage area is determined in chronological order from back to front; the first temporary size is the difference between the target size and the first current size; the determined diagnostic data of the first current size in the second storage area and the diagnostic data of the first temporary size in the first storage area are transferred to the third storage area.

[0067] In this embodiment, the aforementioned content stores the diagnostic test information in the fourth storage area; the aforementioned content transfers the latest diagnostic data of the target size in the first storage area and the second storage area to the third storage area, and uploads the diagnostic data in the third storage area as a diagnostic log to the server, including: transferring the latest diagnostic data of the target size in the first storage area and the second storage area and the diagnostic test information in the fourth storage area to the third storage area, and uploading the diagnostic data in the third storage area and the diagnostic test information as a diagnostic log to the server.

[0068] It should be pointed out that the diagnostic data generated during the diagnostic process is first saved in ArrayDiagnosticData until the size of the record exceeds N, at which time the new diagnostic communication data is recorded in ArrayDiagnosticData_Backup. If the ArrayDiagnosticData_Backup array is also full, the data saved in ArrayDiagnosticData_Backup is copied to ArrayDiagnosticData for replacement, ArrayDiagnosticData_Backup is cleared, and subsequent diagnostic data is re-recorded in ArrayDiagnosticData_Backup, and the cycle is repeated until the diagnostic interrupt condition is triggered. When the diagnostic software triggers the diagnostic interrupt condition, it means that the log needs to be uploaded. The diagnostic software first determines whether the amount of data in ArrayDiagnosticData is less than N. If it is less than N, it means that the diagnostic communication logs are all recorded in this array. At this time, the two arrays ArrayDiagnosticInfo and ArrayDiagnosticData are used to fill ArrayTotalLog and upload it to the background server. For details, see. Figure 5 As shown in the figure, it is a schematic diagram of diagnostic log assembly; if it is equal to N, it means that the recorded diagnostic data has exceeded the maximum value sent by the server and needs to be sorted and uploaded. The diagnostic software obtains the communication data size K saved in ArrayDiagnosticData_Backup, clears the first K lengths of the content in ArrayDiagnosticData, and then moves the content of NK to the front of the array, and then copies the communication content in ArrayDiagnosticData_Backup from the position of NK into the array ArrayDiagnosticData. In this way, the diagnostic communication data will be saved in the ArrayDiagnosticData array from the old to the new, and then the ArrayDiagnosticInfo and ArrayDiagnosticData arrays are used to fill ArrayTotalLog and upload it to the background server. For details, see Figure 6 and Figure 7 As shown, another schematic diagram of assembling a diagnostic log is formed; Figure 6 This is a schematic diagram of another diagnostic log assembly method, which describes the diagnostic log assembly method in detail. Figure 7 This is another diagnostic log leader process diagram, which is for Figure 5 ; if the entire diagnostic process is not interrupted, the four arrays will be destroyed and the memory will be released when exiting the diagnosis.

[0069] In summary, through this application, trigger conditions can be dynamically preset to obtain accurate synchronous diagnostic logs, which is convenient for technicians to troubleshoot and locate problems without burdening the user's computer system and server network. Since the operation is performed on the memory, there will be no frequent file read and write operations, which will not affect the normal diagnostic function, greatly improving the execution efficiency and security of the diagnostic software, reducing complex manual operations, and reducing after-sales costs.

[0070] It can be seen that the present application determines the electronic control unit to be diagnosed in the vehicle to be diagnosed based on the diagnostic test information, diagnoses the electronic control unit to be diagnosed and stores the diagnostic data generated in the diagnostic process in the first storage area; if the diagnostic interruption condition is not triggered until the first storage area is filled, the diagnostic data generated in the subsequent diagnostic process is stored in the second storage area; if the diagnostic interruption condition is not triggered until the second storage area is filled, the first storage area is cleared, the diagnostic data in the second storage area is transferred to the first storage area, and the second storage area is cleared; jump to the step of storing the diagnostic data generated in the subsequent diagnostic process in the second storage area until the diagnostic interruption condition is triggered and stops the diagnosis; transfer the latest target size diagnostic data in the first storage area and the second storage area to the third storage area, and upload the diagnostic data in the third storage area as a diagnostic log to the server. It can be seen that the present application uses the first storage area and the second storage area to store diagnostic data, and because the use of the two areas can delete part of the diagnostic data, avoid too much diagnostic data, avoid affecting the normal flashing process and causing flashing failure, and avoid causing a serious burden on the computer and server bandwidth; in addition, there is no need for a second pass to collect diagnostic data, which reduces the waste of time and resources.

[0071] Correspondingly, the present application embodiment also discloses a diagnostic log assembly device, see Figure 8 As shown, the device comprises:

[0076] The log uploading module 15 is used to transfer the latest diagnostic data of the target size in the first storage area and the second storage area to the third storage area, and upload the diagnostic data in the third storage area to the server as a diagnostic log.
