[0043] 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.

[0044] At present, diagnostic software may encounter development errors that lead to diagnostic failures in daily vehicle diagnosis. Even if maintenance personnel feedback the failure log to the server of the original failed diagnostic software, it is difficult for developers to locate the specific cause of the failure because there is only a failure log and no specific success data in the success log. To this end, the present application provides a method for locating abnormalities in diagnostic equipment. By comparing the log files recorded by the first diagnostic equipment and the second diagnostic equipment during the data collection operation, relevant staff can accurately locate the specific cause of the failure of the diagnosis of the first diagnostic equipment, greatly improving the speed of troubleshooting.

[0045] See also Figure 1 As shown, an embodiment of the present invention discloses a method for locating abnormality of a diagnostic device, comprising:

[0046] Step S11: monitoring whether a function failure prompt of the first diagnostic device is received.

[0047] In this embodiment, the diagnostic head of the first diagnostic device is used to perform diagnostic operations on the vehicle to be diagnosed, and the preset display panel of the first diagnostic device is monitored in real time to see whether there is a function failure prompt. Specifically, the monitoring of whether the function failure prompt of the first diagnostic device is received includes: connecting the first diagnostic device to the diagnostic head of the vehicle to be diagnosed to perform diagnostic operations on the vehicle to be diagnosed, and monitoring whether the preset display panel of the first diagnostic device has the function failure prompt.

[0048] Step S12: If a function failure prompt of the first diagnostic device is received, the diagnostic head interface on the preset three-pronged cable is connected to the diagnostic head of the vehicle to be diagnosed; the preset three-pronged cable also includes a first extension cable interface respectively connected to the diagnostic head interface and a first socket as a diagnostic device interface.

[0049] In this embodiment, when the function failure prompt is detected on the preset display panel of the first diagnostic device, after the user terminal receives the function failure prompt, the user terminal is prompted to prepare the preset three-pronged cable and the preset extension cable, and then the diagnostic head interface of the preset three-pronged cable is connected to the diagnostic head of the vehicle to be diagnosed. The preset three-pronged cable includes a diagnostic head interface connected to the diagnostic head of the vehicle to be diagnosed, a first extension cable interface connected to the diagnostic head interface, and a first socket as a diagnostic device interface. It should be pointed out that as long as the above-mentioned diagnostic head interface, the first extension cable interface, and the preset cable of the first socket exist, they can be used as the preset three-pronged cable.

[0050] Step S13, establishing a data transmission link between the preset three-pronged cord and the preset extension cord by connecting the first extension cord interface on the preset three-pronged cord with the second extension cord interface on the preset extension cord; wherein the preset extension cord also includes a second socket connected to the second extension cord interface and serving as a diagnostic equipment interface.

[0051] In this embodiment, after the preset extension line is prepared and the diagnostic head interface on the preset three-pronged line is connected to the diagnostic head of the vehicle to be diagnosed, a data transmission link between the preset three-pronged line and the preset extension line needs to be established. Specifically, the first extension line interface on the preset three-pronged line and the second extension line interface on the preset extension line are connected to establish a data transmission link between the preset three-pronged line and the preset extension line.

[0052] Step S14: connect the first diagnostic device to the first socket and connect a second diagnostic device with normal functions to the second socket, so as to perform data acquisition operations on the data output by the diagnostic head through the first diagnostic device and the second diagnostic device respectively.

[0053] In this embodiment, before connecting the second diagnostic device to the second socket, it is necessary to determine whether the second diagnostic device functions normally, that is, to determine whether the second diagnostic device captures a data stream that satisfies a preset state. If the second diagnostic device captures a data stream that satisfies a preset state, the second diagnostic device is a second diagnostic device that functions normally. Specifically, before connecting the first diagnostic device to the first socket and connecting a second diagnostic device that functions normally to the second socket, it also includes: connecting the second diagnostic device to the diagnostic head of the vehicle to be diagnosed, and determining whether the second diagnostic device captures a data stream that satisfies a preset state; if the second diagnostic device captures a data stream that satisfies a preset state, the second diagnostic device is determined to be a diagnostic device that functions normally.

[0054] In a specific implementation, the camera calibration function of the second diagnostic device is used to determine whether the second diagnostic device captures a data stream that satisfies a preset state. Specifically, it is determined whether the second diagnostic device captures a specific byte of a communication data stream command. If the second diagnostic device captures the specific byte of a communication data stream command, the second diagnostic device is determined to be a normal diagnostic device.

[0055] It can be understood that before the first diagnostic device and the second diagnostic device respectively perform data acquisition operations on the data output by the diagnostic head, data acquisition configuration files corresponding to each diagnostic function are respectively established based on the first diagnostic device and the second diagnostic device, and the data acquisition configuration files contain the communication configuration data of all ECUs (Electronic Control Units). Specifically, before the first diagnostic device and the second diagnostic device respectively perform data acquisition operations on the data output by the diagnostic head, it also includes: respectively establishing data acquisition configuration files corresponding to each diagnostic function of the first diagnostic device and the second diagnostic device; wherein the data acquisition configuration files include the communication configuration data corresponding to the electronic control units of each vehicle type; the communication configuration data includes communication baud rate data, filter number data, pin data, and flow control data.

[0056] In a specific implementation, for example, CANBUS (Controller Area Network-BUS), the following communication configuration data is required: communication baud rate, such as 500K; filter ID, such as 0x18DAF130|0x18DA30F1; pins, such as pins 6-14; flow control data, such as 3000000000000000. It should be noted that if multiple ECU data need to be collected, multiple groups of communication configuration data are set.

[0057] Further, after the preset data acquisition configuration file is established, the first diagnostic device and the second diagnostic device are respectively monitored, so as to perform data acquisition operations on the data output by the diagnostic head of the vehicle to be diagnosed based on the preset data acquisition configuration file, so as to obtain corresponding first acquisition data and second acquisition data, and perform binary conversion on the first acquisition data and the second acquisition data, so as to obtain a first log file and a second log file. Specifically, the data acquisition operations on the data output by the diagnostic head respectively through the first diagnostic device and the second diagnostic device include: monitoring the diagnostic head through the first diagnostic device, and performing data acquisition operations on the data output by the diagnostic head using the data acquisition configuration file, so as to obtain corresponding first output data, and performing binary conversion on the data type of the first output data, so as to obtain a corresponding first log file; monitoring the diagnostic head through the second diagnostic device, and performing data acquisition operations on the data output by the diagnostic head using the data acquisition configuration file, so as to obtain corresponding second output data, and performing binary conversion on the data type of the second output data, so as to obtain a corresponding second log file.

[0058] It can be further understood that the first diagnostic device uses the preset data acquisition configuration file to start the data acquisition mode, so as to perform data acquisition on the data output by the diagnostic head to obtain first acquired data, and performs binary conversion on the first acquired data to obtain a first log file, and records the second log file in a local file of the first diagnostic device. At this time, the first diagnostic device can prompt the client to use the second diagnostic device to diagnose the vehicle to be diagnosed on the preset display panel, and perform data acquisition on the data output by the diagnostic head to obtain the second acquired data, and perform binary conversion on the second acquired data to obtain the second log file.

[0059] Step S15: comparing the log files recorded by the first diagnostic device and the second diagnostic device respectively during the data collection operation to locate the functional abnormality of the first diagnostic device.

[0060] In this embodiment, after obtaining the first log file and the second log file, the first log file and the second log file are uploaded to the corresponding preset feedback server, so as to compare the abnormal data of the first log file that is different from the second log file based on the preset feedback server, and locate the functional abnormality of the first diagnostic device through the abnormal data. Specifically, the functional abnormality of the first diagnostic device is located by comparing the log files recorded by the first diagnostic device and the second diagnostic device respectively during the data collection operation, including: uploading the first log file and the second log file to the preset feedback server, and comparing the first log file and the second log file through the feedback server to obtain the abnormal data in the first log file that is different from the second log file; and locating the functional abnormality of the first diagnostic device based on the abnormal data in the first log file.

[0061] As can be seen from the above, if the function failure prompt of the first diagnostic device is received, the diagnostic head interface on the preset three-pronged line is connected to the diagnostic head of the vehicle to be diagnosed, and the first extension line interface on the preset three-pronged line is connected to the second extension line interface on the preset extension line, and then the first diagnostic device is connected to the first socket and the second diagnostic device with normal function is connected to the second socket, and the data output by the diagnostic head can be collected by the first diagnostic device and the second diagnostic device respectively. In this way, by comparing the log files recorded by the first diagnostic device and the second diagnostic device during the data collection operation, the relevant staff can accurately locate the specific reason for the failure of the diagnosis of the first diagnostic device, greatly improving the speed of troubleshooting.

[0062] Furthermore, in order to more clearly illustrate the connection between the preset three-pronged cable and the preset extension cable, Figure 2 A connection diagram of a preset three-pronged line and a preset extension line provided for this application includes:

[0063] After receiving a function failure prompt of the first diagnostic device, the diagnostic head interface on the preset three-pronged cable is connected to the diagnostic head of the vehicle to be diagnosed, the preset three-pronged cable includes the diagnostic head interface connected to the diagnostic head, the first extension cable interface connected to the preset extension cable, and a first socket serving as a diagnostic device interface; then the first extension cable interface on the preset three-pronged cable and the second extension cable interface on the preset extension cable are connected to establish a data transmission link between the preset three-pronged cable and the preset extension cable, the preset extension cable includes the second extension cable interface and a second socket serving as a diagnostic device interface.

[0064] The first diagnostic device is connected to the first socket of the preset three-pronged cable, and the second diagnostic device is connected to the second socket of the preset extension cable, so as to achieve the effect of dividing the diagnostic head of the vehicle to be diagnosed into two. In this way, the first diagnostic device and the second diagnostic device can be used to perform data acquisition operations on the data output by the diagnostic head respectively, and the functional abnormality of the first diagnostic device can be located by comparing the data collected by the first diagnostic device and the second diagnostic device.

[0068] The transmission link establishing module 13 is used to establish a data transmission link between the preset three-pronged cable and the preset extension cable by connecting the first extension cable interface on the preset three-pronged cable with the second extension cable interface on the preset extension cable; wherein the preset extension cable also includes a second socket connected to the second extension cable interface and serving as a diagnostic equipment interface;

In this way, by comparing the log files recorded by the first diagnostic device and the second diagnostic device during the data collection operation, the relevant staff can accurately locate the specific reason for the failure of the diagnosis of the first diagnostic device, greatly improving the speed of troubleshooting.
