Description

Technical Field

[0001] The present invention relates to the field of vehicle diagnosis technology, and in particular to a vehicle data stream waveform display method, device, equipment and medium. Background Art

[0002] The vehicle data stream can truly reflect the working voltage and status of each sensor and actuator in the vehicle, and provide a basis for vehicle fault diagnosis. Therefore, data stream analysis is an important method in modern vehicle maintenance and inspection. Among them, waveform display is an intuitive and effective analysis method, which can display each parameter in the data stream in the form of a waveform, so that users can analyze by viewing the changes in the data stream waveform. At present, the existing vehicle data stream waveform display method only directly connects all the sampled data points in the read data stream linearly in sequence to form a simple linear waveform diagram for users to view. However, this method will still linearly connect the interfering sampling points in the presence of interfering sampling points, causing interference, and cannot achieve an intuitive display of the data stream change trend, which is inconvenient for users to analyze.

[0040] 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.

[0041] At present, the existing vehicle data stream waveform display method only directly connects all the sampling data points in the read data stream linearly in sequence to form a simple linear waveform graph for users to view. However, in the presence of interfering sampling points, this method will still linearly connect the interfering sampling points, causing interference, and cannot achieve an intuitive display of the data stream change trend, which is inconvenient for users to analyze.

[0042] In order to overcome the above technical problems, the present application provides a vehicle data stream waveform display method to optimize the vehicle data stream waveform display method so that users can intuitively analyze the change trend of the vehicle data stream.

[0043] See also Figure 1 As shown, an embodiment of the present invention discloses a vehicle data stream waveform display method, comprising:

[0044] Step S11: reading a plurality of data streams corresponding to the vehicle to be detected from the vehicle to be detected based on the received data stream reading instruction, so as to obtain a plurality of sampled data corresponding to the plurality of data streams.

[0045] In this embodiment, a plurality of data streams corresponding to the vehicle to be detected are read from the vehicle to be detected according to the received data stream reading instruction to obtain a plurality of sampled data corresponding to the plurality of data streams. The vehicle to be detected is a vehicle that requires the user to diagnose by viewing the data stream; the sampled data is data obtained by sampling the read data stream.

[0046] It should be pointed out that when a vehicle has a problem such as a malfunction, maintenance personnel can diagnose the malfunctioning vehicle by viewing the data stream of the malfunctioning vehicle and analyzing its trend. Therefore, the vehicle data stream waveform display method provided by the present invention can be applied to diagnostic equipment, that is, equipment that can display the vehicle data stream in the form of a waveform so that diagnostic personnel can diagnose the vehicle. It can be understood that the data stream reading instruction can be an instruction automatically generated when the user connects the diagnostic device to the diagnostic interface of the vehicle to be detected and turns on the diagnostic device, or it can be an instruction obtained through a preset reading interface. Among them, the preset reading interface can be the front end of the diagnostic device. Specifically, after the diagnostic device is connected to the diagnostic interface of the vehicle to be detected, the user turns on the diagnostic device and clicks the preset button on the front end of the diagnostic device to start reading the data stream, so that the diagnostic device obtains the data stream reading instruction through the preset reading interface.

[0047] It should be noted that the present embodiment can preset a mapping relationship table between the signal characteristics of the currently known data stream and the corresponding processing methods in the diagnostic device, that is, a preset processing method table, and its processing flow is as follows: determine a number of signal characteristics and a number of processing methods corresponding to the signal characteristics based on the received mapping table setting instruction; construct a preset processing method table based on the signal characteristics, the processing methods and the mapping relationship between the signal characteristics and the processing methods. The mapping table setting instruction is obtained through a preset setting interface, including the signal characteristics set by the user and the processing methods corresponding to the signal characteristics; the preset setting interface can be the front end of the diagnostic device or the back end of the diagnostic device, and is set by the developer. That is, a mapping table setting instruction initiated by a developer is received through a preset setting interface, and then a number of signal features set by the developer and a number of processing methods corresponding to the signal features are determined from the mapping table setting instruction, and the mapping relationship between the signal features and the processing methods is determined, so as to construct the preset processing method table based on the signal features, the processing methods, and the mapping relationship between the signal features and the processing methods, so as to determine the processing method corresponding to the data stream to be displayed through the preset processing method table when the waveform display of the vehicle data stream is required, and realize the waveform display of the vehicle data stream using the processed data. In this way, this embodiment reads a number of data streams corresponding to the vehicle to be detected from the vehicle to be detected based on the received data stream reading instruction, so as to quickly determine the data stream to be displayed from the data streams when the data stream display instruction is received later, thereby improving the efficiency of the vehicle data stream waveform display.

[0048] Step S12: determining a data stream to be displayed from the plurality of data streams according to the received data stream display instruction, determining a target signal feature of the data stream to be displayed from a plurality of preset signal features, and determining target sampling data corresponding to the data stream to be displayed from the plurality of sampling data according to the data stream to be displayed.

[0049] In this embodiment, the data stream to be displayed is determined from the plurality of data streams according to the received data stream display instruction, and the target signal feature of the data stream to be displayed is determined from the preset plurality of signal features, and the target sampling data corresponding to the data stream to be displayed is determined from the plurality of sampling data according to the determined data stream to be displayed. The data stream display instruction is an instruction obtained through a preset display interface, including the data stream to be displayed selected by the user for waveform display and the set target signal feature of the data stream to be displayed, and the preset display interface can be the front end of the diagnostic device; the target signal feature includes the waveform type of the data stream, and the waveform type includes but is not limited to a stable DC wave, a pulsating AC wave, a ripple DC wave, a square wave, a sine wave, etc.

[0050] It can be understood that the preset signal features are determined based on the signal features of the currently known data streams. If a temporarily unknown signal feature appears, the target signal feature of the data stream to be displayed cannot be determined from the preset signal features. Therefore, this embodiment can continuously update the preset signal features according to the determination of the data stream to be displayed, and its processing flow is as follows: if the target signal feature corresponding to the data stream to be displayed does not exist in the preset signal features, then trigger the feature supplementary feedback for the data stream to be displayed to obtain the supplemented target signal feature, and save the supplemented target signal feature and the corresponding processing method to the preset processing method table. It should be pointed out that the preset signal features can be the signal features determined when the preset processing method table is preset. That is, when the target signal feature corresponding to the data stream to be displayed does not exist in the preset signal features, this embodiment can trigger the feature supplementary feedback for the data stream to be displayed, so as to obtain the supplemented target signal feature, and save the supplemented target signal feature and the corresponding processing method to the preset processing method table. Specifically, when the target signal feature corresponding to the data stream to be displayed cannot be determined from the preset signal features, this embodiment can provide feedback to the front end of the diagnostic device indicating that the target signal feature is not currently supported, so that the user operating the diagnostic device is aware of the situation, and provides feedback to the developer through the official platform or contact information of the diagnostic device to supplement the preset signal features. In addition, this embodiment can also directly provide feature supplement feedback to the background of the diagnostic device, package the target signal feature and the data stream to be displayed into a feature supplement request, and send it to the background to obtain the developer's supplement to the preset processing method table in response to the feature supplement request. In this way, this embodiment determines the data stream to be displayed and the target signal feature and target sampling data corresponding to the data stream to be displayed according to the received data stream display instruction, so that the processing method corresponding to the data stream to be displayed can be determined according to the target signal feature later, which is convenient for users to view the waveform of the data stream to be displayed.

[0051] Step S13, determine whether there is a processing method corresponding to the target signal feature in the preset processing method table, and determine the target processing method of the target signal feature based on the judgment result, so as to process the target sampling data using the target processing method, and display the waveform of the data stream to be displayed based on the processed target sampling data.

[0052] In this embodiment, it is first determined whether there is a processing method corresponding to the target signal feature in the preset processing method table, and then the target processing method of the target signal feature is determined based on the obtained judgment result, so as to process the target sampling data using the target processing method, and the waveform of the data stream to be displayed is displayed based on the processed target sampling data. Among them, the preset processing method table is a mapping relationship table of the preset signal features of the currently known data streams and the corresponding processing methods; the processing method includes a filtering method, and the filtering method includes but is not limited to filtering methods for waveforms such as stable DC waves, pulsating AC waves, ripple DC waves, square waves, and sine waves.

[0053] Specifically, this embodiment determines whether there is a processing method corresponding to the target signal feature in the preset processing method table. If there is a processing method corresponding to the target signal feature in the preset processing method table, the processing method is used as the target processing method for the target signal feature, and then the parameter information corresponding to the target processing method is determined through the parameter setting interface; the target sampling data is processed based on the parameter information and the target processing method to obtain processed waveform data; and the waveform data is used to display the waveform of the data stream to be displayed. That is, the parameter information corresponding to the target processing method input by the user is obtained through the parameter setting interface of the diagnostic device, and the target sampling data is processed based on the parameter information using the target processing method to obtain processed waveform data, and the waveform data is used to display the waveform of the data stream to be displayed at the front end of the diagnostic device.

[0054] It should be noted that the specific content of the parameter information varies according to the characteristics of the target signal. For example, if the signal characteristic of a data stream is a stable DC wave, the user can set parameter information of the current data stream such as the standard value and the error range through the diagnostic device, and process the data stream based on the parameter information. Assuming that the user sets the standard value to 1A (i.e., Ampere) and the error range to plus or minus 0.1A, the data in the data stream that is based on 1A and floats to plus or minus 0.1A can be processed so that all these data are displayed as 1A, thereby filtering out line interference and intuitively displaying the changing trend of the data stream; if the signal characteristic of a data stream is a square wave, the user can set parameter information of the current data stream such as the high and low level range through the diagnostic device, and process the data stream based on the parameter information. Assuming that the user sets 3V-5V (i.e., Volt) as the high level of the current data stream and 0V-3V as the low level of the current data stream, the data stream is processed based on the user's settings so that data with a voltage value of 3V-5V are all displayed as 5V, and data with a voltage value lower than 3V are displayed as 0V, so that the user can view it at the front end of the diagnostic device.

[0055] It should be further pointed out that in order to improve the personalization of the data stream processing method, the user can change the mapping relationship between the signal characteristics and the processing method in the preset processing method table based on his own needs during use. The processing flow is as follows: based on the received mapping table change instruction, determine the signal characteristics to be changed in the preset processing method table, and the processing method to be changed corresponding to the signal characteristics to be changed; based on the signal characteristics to be changed and the processing method to be changed, change the preset processing method table, and feedback the monitored change results so that the background analyzes the change results, and based on the obtained analysis results, determine whether it is necessary to optimize the locally saved default processing method table. Among them, the mapping table change instruction includes the change information set by the user based on his own needs, which is obtained through the preset change interface, and the preset change interface can be the front end of the diagnostic device; the default processing method table is a processing method table preset by the developer according to the known signal characteristics of the data stream during the development process. That is, the signal characteristics to be changed and the corresponding processing methods to be changed are determined from the received mapping table change instruction, and the signal characteristics to be changed and the processing methods to be changed are determined from the preset processing method table, and the preset processing method table is changed using the signal characteristics to be changed and the processing methods to be changed, and the change results detected by the diagnostic device are fed back to the background, so that the developer can analyze the received change results and judge whether it is necessary to optimize the default processing method table saved locally based on the obtained analysis results. Specifically, when the user needs to change the preset processing method table, this embodiment can display the signal characteristics and processing methods in the preset processing method table to the user at the front end of the diagnostic device for the user to select and set to meet the user's personalized needs. In this way, this embodiment uses the determined target processing method to process the target sampling data, so as to display the processed sampling data in waveform, filter out interference data, and better reflect the data change trend; at the same time, it supports users to change the preset processing method table according to their own needs, improve the personalization of the data stream processing method, and meet the personalized needs of users.

[0056] As can be seen from the above, the embodiment of the present application first reads the corresponding data streams from the vehicle to be detected based on the received data stream reading instruction to obtain the several sampling data corresponding to the several data streams, determines the data stream to be displayed from the several data streams based on the received data stream display instruction, and determines the target signal characteristics of the data stream to be displayed from the preset signal characteristics and the corresponding target sampling data from the several sampling data, then determines whether there is a processing method corresponding to the target signal characteristics in the preset processing method table, and determines the target processing method based on the judgment result, so as to process the target sampling data using the target processing method, and perform waveform display based on the processed target sampling data. In this way, through the above process of the embodiment of the present application, on the one hand, based on the received data stream reading instruction, several data streams corresponding to the vehicle to be detected are read from the vehicle to be detected, so that when the data stream display instruction is received later, the data stream to be displayed can be quickly determined from the several data streams, thereby improving the efficiency of the vehicle data stream waveform display; on the one hand, the data stream to be displayed and the target signal characteristics and target sampling data corresponding to the data stream to be displayed are determined according to the data stream display instruction, so that the corresponding processing method can be determined according to the target signal characteristics later, which is convenient for users to view the waveform diagram of the data stream to be displayed; on the one hand, it supports users to change the preset processing method table according to their own needs, improves the personalization of the data stream processing method, and meets the personalized needs of users; on the other hand, the target sampling data is processed using the target processing method determined according to the signal characteristics of the vehicle data stream, so that the processed sampling data is displayed as a waveform, which can filter out interference data and better reflect the data change trend, thereby optimizing the waveform display method of the vehicle data stream so that users can intuitively analyze the change trend of the vehicle data stream.

[0057] Based on the above embodiments, it can be known that, through the method of the present application, when determining the target processing method corresponding to the data stream to be displayed, the target processing method can be determined according to the target signal characteristics of the data stream to be displayed, so as to filter the interference data in the data stream to be displayed, thereby facilitating the user to more intuitively analyze the change trend of the vehicle data stream. For this reason, this embodiment describes in detail how to determine the target processing method according to the target signal characteristics of the data stream to be displayed. Figure 2 As shown, a vehicle data stream waveform display method disclosed in an embodiment of the present invention includes:

[0058] Step S21: reading a plurality of data streams corresponding to the vehicle to be detected from the vehicle to be detected based on the received data stream reading instruction, so as to obtain a plurality of sampled data corresponding to the plurality of data streams.

[0059] Step S22: determine a data stream to be displayed from the plurality of data streams according to the received data stream display instruction, determine a target signal feature of the data stream to be displayed from a plurality of preset signal features, and determine target sampling data corresponding to the data stream to be displayed from the plurality of sampling data according to the data stream to be displayed.

[0060] Step S23: determine whether there is a processing method corresponding to the target signal feature in the preset processing method table.

[0061] Step S24: If the obtained judgment result indicates that a processing method corresponding to the target signal feature exists in the preset processing method table, the processing method corresponding to the target signal feature in the preset processing method table is used as the target processing method for the target signal feature.

[0062] In this embodiment, when the judgment result obtained indicates that there is a processing method corresponding to the target signal feature in the preset processing method table, the processing method corresponding to the target signal feature in the preset processing method table is determined, and the processing method is used as the target processing method of the target signal feature. It can be understood that the preset processing method table is a mapping relationship table between the signal feature of the data stream and its corresponding processing method pre-set by the developer during development. Based on the preset processing method table, the target processing method corresponding to the target signal feature can be quickly determined, thereby improving the efficiency and accuracy of the vehicle data stream waveform display. At the same time, the user can customize the target processing method corresponding to the target signal feature according to his own waveform display requirements, thereby realizing the personalization of the method. In this way, when there is a processing method corresponding to the target signal feature in the preset processing method table in this embodiment, the processing method corresponding to the target signal feature in the preset processing method table is directly used as the target processing method, thereby improving the efficiency of the vehicle data stream waveform display.

[0063] Step S25: If the judgment result indicates that there is no processing method corresponding to the target signal feature in the preset processing method table, the preset default processing method is used as the target processing method for the target signal feature.

[0064] In this embodiment, when the judgment result indicates that the processing method corresponding to the target signal feature does not exist in the preset processing method table, the preset default processing method is used as the target processing method for the target signal feature. It should be pointed out that when the judgment result indicates that the processing method corresponding to the target signal feature does not exist in the preset processing method table, it means that the target signal feature does not belong to any of the preset signal features. In this embodiment, the preset default processing method can be used as the target processing method for the target signal feature. Among them, the default processing method is to directly linearly connect the sampled data in sequence to obtain a processing method for linear waveform data.

[0065] It should be further pointed out that, when the judgment result indicates that the processing method corresponding to the target signal feature does not exist in the preset processing method table, the present embodiment can simultaneously trigger feedback on the judgment result, and its processing flow is as follows: If the judgment result indicates that the processing method corresponding to the target signal feature does not exist in the preset processing method table, the preset default processing method is used as the target processing method for the target signal feature, and supplementary feedback on the processing method for the target signal feature is triggered, so that the preset processing method table is supplemented and updated for the target signal feature through the mapping table supplement interface. That is, when the judgment result indicates that the processing method corresponding to the target signal feature does not exist in the preset processing method table, the present embodiment can trigger supplementary feedback on the processing method for the target signal feature while using the default processing method as the target processing method for the target signal feature, so that the preset processing method table for the target signal feature is supplemented and updated through the mapping table supplement interface. In this way, when the processing method corresponding to the target signal feature does not exist in the preset processing method table, this embodiment uses the preset default processing method as the target processing method, and triggers relevant supplementary feedback to continuously supplement and update the preset processing method table based on user usage, thereby improving the scope of use of the preset processing method table and the accuracy of the vehicle data stream waveform display.

[0066] Step S26: Process the target sampling data using the target processing method, and display the waveform of the data stream to be displayed based on the processed target sampling data.

[0067] Among them, the specific implementation process of steps S21, S22, S23 and S26 can refer to the contents of the aforementioned embodiments, and will not be repeated here.

[0068] As can be seen from the above, the embodiment of the present application first reads the corresponding data streams from the vehicle to be detected based on the received data stream reading instruction to obtain the corresponding sampled data of the data streams, determines the data stream to be displayed from the data streams based on the received data stream display instruction, and determines the target signal feature of the data stream to be displayed from the preset signal features and the corresponding target sampled data from the sampled data, then determines whether there is a processing method corresponding to the target signal feature in the preset processing method table, and when the judgment result indicates that there is a processing method corresponding to the target signal feature, the processing method is used as the target processing method for the target signal feature, and when the judgment result indicates that there is no processing method corresponding to the target signal feature, the preset default processing method is used as the target processing method for the target signal feature, so that the target sampling data can be processed using the target processing method, and a waveform display is performed based on the processed target sampling data. In this way, through the above process of the embodiment of the present application, on the one hand, when the processing method corresponding to the target signal feature exists in the preset processing method table, the processing method corresponding to the target signal feature in the preset processing method table is directly used as the target processing method, thereby improving the efficiency of the vehicle data stream waveform display; on the other hand, when the processing method corresponding to the target signal feature does not exist in the preset processing method table, the preset default processing method is used as the target processing method, and relevant supplementary feedback is triggered at the same time, so as to continuously supplement and update the preset processing method table based on user usage, thereby improving the scope of use of the preset processing method table and the accuracy of the vehicle data stream waveform display, thereby facilitating users to more intuitively analyze the changing trends of vehicle data streams.

[0069] Accordingly, see Figure 3 As shown, the embodiment of the present application also provides a vehicle data stream waveform display device, including:
