Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
Among the data streams generated by the vehicle, there are data streams with sub items and data streams without sub items. Current diagnostic devices often employ a uniform display configuration to display the various data streams after they have been read into the vehicle. When a user consults, the user cannot clearly determine which data streams are sub-items and which data streams are main items; it is also not clear which data streams carry sub-items and which do not. This results in a data stream with a weaker display hierarchy and a distracting display effect. Based on this, an embodiment of the present application provides a data stream display method, a data stream display apparatus, a diagnostic device, and a computer-readable storage medium, where different display templates are configured for a data stream carrying a sub-item and a data stream not carrying a sub-item, so that readability of the data stream can be improved. In order to explain the technical solutions proposed in the embodiments of the present application, the following description will be given by way of specific examples.
A data stream display method provided in an embodiment of the present application is described below. Referring to fig. 1, the data stream display method includes:
in the embodiment of the present application, the data stream set refers to a set made up of at least one data stream that can be output by the vehicle to be diagnosed. By way of example only, the set of data streams may include: the data flow of the number of fault codes, the temperature of the engine coolant, and the monitored state since the last clearing of the fault memory is not limited herein. The diagnostic device may output the data stream set in a data stream selection interface, specifically, output a data stream name corresponding to each data stream in the data stream set; then receiving a data stream selection instruction input based on the data stream set; and finally, determining the data stream pointed by the data stream selection instruction as the data stream to be viewed in the data stream set. That is, the user may select a data stream of interest to the user as the data stream to be viewed from the data stream set. It should be noted that the number of data streams to be viewed is not limited in the embodiments of the present application. That is, the user may select one, two, or more data streams in the set of data streams as the data streams to be viewed.
Alternatively, considering that there are often a plurality of electronic and electrical systems in a vehicle, the data streams that each electronic and electrical system can output are different, and therefore, a corresponding data stream set may be configured for each electronic and electrical system. After the diagnostic equipment is connected with the vehicle to be diagnosed, all electronic and electrical systems of the vehicle to be diagnosed can be displayed firstly, a system selection instruction input by a user is received, and the electronic and electrical system pointed by the system selection instruction is determined as a target electronic and electrical system; and then outputting a data stream set associated with the target electronic and electrical system, and receiving a data stream selection instruction input by a user based on the data stream set, so as to determine a data stream to be viewed, which is not described herein again.
102, obtaining label information of a data stream to be checked, wherein the label information is used for indicating whether the data stream to be checked carries sub-items;
in the embodiment of the present application, the diagnostic device labels each data stream in advance according to whether the data stream carries a sub-item. Based on this, after the diagnostic device determines the data stream to be checked, it is known whether the data stream to be checked is a data stream carrying the sub-items by looking up the label information of the data stream to be checked. For example, the number of fault codes is a data stream that does not carry sub-entries; the monitoring state since the last time the fault memory is cleared is a data stream carrying sub-items, which include: a number of fault code memory entries associated with the emissions; the operating status of the exhaust fault indicator light; a monitored condition of the ignition misfire; monitoring status of the fuel system, etc.
103, if the marking information indicates that the data stream to be checked carries sub-items, determining a first display template as a target display template;
in the embodiment of the present application, the diagnostic device configures different display templates in advance for the data stream carrying the sub-item and the data stream not carrying the sub-item. For convenience of description, the display template corresponding to the data stream carrying the sub-item is determined as a first display template, and the display template corresponding to the data stream not carrying the sub-item is determined as a second display template. Based on this, the diagnostic device may determine whether the data stream to be checked carries the sub-item according to the tagging information, and then determine a corresponding display template for the data stream to be checked based on a condition that whether the data stream to be checked carries the sub-item.
in the embodiment of the application, the data value associated with the data stream to be viewed in the vehicle to be diagnosed can be read through a preset data reading interface (namely, a diagnosis interface). It should be noted that, for the data stream to be viewed carrying the sub-items, the main item can be regarded as the category to which the sub-items belong; that is, there is actually no associated data value for the main item itself, and only the individual sub items have associated sub item data values. For example, for the data flow of the monitoring state since the last time the fault memory was cleared, the "monitoring state since the last time the fault memory was cleared" is the primary item, and the primary item does not have an associated data value, that is, there is no data value that can directly describe the "monitoring state since the last time the fault memory was cleared"; the four sub-items under the main item have associated data values, that is, data values associated with "the number of emission-related fault code memory entries", data values associated with "the operating state of the exhaust fault indicator lamp", data values associated with "the monitoring state of the ignition misfire", and data values associated with "the monitoring state of the fuel system" actually exist. Based on this, the diagnostic device may obtain at least one sub-item belonging to the data stream to be viewed and obtain sub-item data values associated with the respective sub-items, respectively, when the annotation information indicates that the data stream to be viewed carries the sub-items.
And 106, filling the target display template based on the data stream name and the data value of the data stream to be checked, and outputting the filled target display template to a display interface.
In the embodiment of the application, whether the first display template or the second display template exists, the corresponding content to be filled exists; these contents to be filled need to be filled by the diagnostic device. The filling process is described below:
for the first display template, the contents to be filled in include but are not limited to: data stream name (i.e., main item name), sub item name, and sub item data value. Therefore, the first display template may be configured with a data stream name column, an expand/collapse icon and a pull-down interface, where the expand/collapse icon is used to expand/collapse the pull-down interface, and the pull-down interface is configured with a sub-item name column and a sub-item data value column. When the first display template is used as a target display template for filling, the diagnostic equipment firstly obtains the data stream name of the data stream to be viewed and also respectively obtains the sub-item names of all the sub-items; then, the diagnostic equipment fills the data stream name of the data stream to be viewed into the data stream name column of the target display template, and in a default state, the pull-down interface is not expanded, and at the moment, the expansion/retraction icon is specifically displayed as an expansion icon; if the user clicks the expansion icon, so that the diagnosis equipment receives an expansion instruction input based on the expansion icon, the diagnosis equipment calls a pull-down interface in the target display template, and the expansion icon is switched and displayed to be a retraction icon; and the diagnostic equipment respectively fills the sub-item names of the sub-items into the sub-item name columns of the drop-down interface, and also respectively fills the sub-item data values associated with the sub-items into the sub-item data value columns of the drop-down interface. It should be noted that, in order to reflect the association of the sub-item with the main item, the sub-item name displayed in the sub-item name column in the drop-down interface may be indented to the right compared to the data stream name displayed in the corresponding data stream name column. Assume that the data stream to be viewed is data stream A, under which sub-items A1, A2, and A3 are contained, and the data value associated with sub-item A1 is a1, the data value associated with sub-item A2 is a2, and the data value associated with sub-item A3 is A3. Referring to FIGS. 2-1 and 2-2, FIG. 2-1 is a schematic view of a first display template when the drop-down interface is not deployed; fig. 2-2 shows a schematic view of the first display template when the drop-down interface is deployed.
For the second display template, the contents to be filled in include but are not limited to: a data stream name and a data value. Thus, the second display template may be configured with a data stream name field and a data value field. When the second display template is used as a target display template for filling, the diagnostic equipment acquires the data stream name of the data stream to be viewed and reads the data value associated with the data stream; the diagnostic device then populates the data stream name of the data stream to be viewed into the data stream name field of the target display template, while populating the data value field of the target display template with the data values associated with the data stream to be viewed. Assume that the data stream to be viewed is data stream B and the data value associated with this data stream B is B. Referring to fig. 2-3, fig. 2-3 are schematic diagrams of a second display template.
Optionally, in order to manage the data stream more orderly, before the step 101, the data stream display method may further include:
respectively configuring associated data stream sequence numbers for each data stream in the data stream set;
accordingly, the step 105 includes:
acquiring a data stream sequence number associated with the data stream to be checked;
and reading and obtaining a data value associated with the data stream to be checked in the vehicle to be diagnosed based on the data stream serial number associated with the data stream to be checked through a preset data reading interface.
The diagnostic device may configure the associated data stream sequence number for each data stream in the data stream set in advance, so that each data stream is uniquely associated with one data stream sequence number. For example, assuming that there are four data streams A, B, C and D in the data stream set, the data stream sequence numbers associated with the data streams may be configured backwards by "1", specifically: the data stream sequence number associated with data stream a is 1, the data stream sequence number associated with data stream B is 2, the data stream sequence number associated with data stream C is 3, and the data stream sequence number associated with data stream D is 4. If the data stream a is determined to be the data stream to be checked, the diagnostic device may read the data stream No. 1 through a preset data reading interface, that is, may obtain the data value associated with the data stream a, and to some extent, increase the reading speed of the data value.
Optionally, in order to make a user intuitively know whether a data value associated with a certain data stream is abnormal, before step 106, the data stream display method further includes:
acquiring a standard value range associated with the data stream to be checked from a preset database;
judging the data value according to the standard value range, and determining the value state associated with the data stream to be checked;
correspondingly, the filling the target display template based on the data stream name and the data value of the data stream to be viewed includes:
populating the target display template based on the data stream name, the data value, the standard value range, and the value status.
Wherein for certain data streams, the diagnostic device can pre-configure the associated standard value range in the database. After the diagnostic device reads the data value associated with the data stream to be viewed, the standard value range associated with the data stream to be viewed can be acquired from the database, and the acquired data value is judged to determine the value state of the data value. It should be noted that, for data streams with sub-items, the diagnostic device may pre-configure the standard value ranges associated with the respective sub-items to determine whether the corresponding sub-item data values are abnormal.
Illustratively, the value states include both normal and abnormal states. The diagnostic device may first detect whether a data value falls within a corresponding standard value range, may determine that a value status associated with the data stream to be viewed is normal when the data value falls within the standard value range, and may determine that the value status associated with the data stream to be viewed is abnormal when the data value is outside the corresponding standard value range. It should be noted that, for a data stream with sub-items, the diagnostic device will sequentially detect whether each sub-item data value falls within the standard value range of the corresponding sub-item, and when the sub-item data value falls within the standard value range of the corresponding sub-item, the value state associated with the sub-item may be determined to be normal, and when the sub-item data value is out of the standard value range of the corresponding sub-item, the value state associated with the sub-item may be determined to be abnormal.
In this case, a value status bar may be additionally configured in each of the first display template and the second display template, so that the diagnostic device may fill the value status bar according to the determined value status. In addition, the first display template and the second display template may further be configured with a unit column and a standard value range column, wherein the unit column is used for displaying the corresponding data value and the unit of the sub-item data value, and the standard value range column is used for displaying the corresponding data value and the standard value range of the sub-item data value.
In some embodiments, the diagnostic device may directly populate the (sub) data value column with the (sub) data value and the unit of the (sub) data value, which is not limited herein.
In some embodiments, for a data stream that does not carry a child item, the diagnostic device may directly highlight the data value associated with the data stream if the value state associated with the data stream is abnormal. Accordingly, for a data stream carrying a sub item, if the value state associated with a sub item under the data stream is abnormal, the diagnostic device may directly highlight the data value of the sub item associated with the sub item.
For the first display template, assume that the data stream to be viewed is data stream A, under which the sub-items A1, A2 and A3 are included; the data value associated with the sub item a1 is a1, there is no standard value range associated with the sub item a1, and the unit of the data value is null; the data value associated with sub-entry A2 is a2, the standard value range associated with sub-entry A1 is [ a4, a5], and the Unit of the data value is Unit-1; the data value associated with sub-entry A3 is A3, and the standard value range associated with sub-entry A1 is [ a6, a7], the unit of which is null. Referring to FIG. 3-1, FIG. 3-1 illustrates a first display template when the drop-down interface is deployed. It is noted that in this application scenario, the first display template is unchanged when the drop-down interface is not deployed, as can be seen in fig. 2-1.
For the second display template, assume that the data stream to be viewed is data stream B, the data value associated with the data stream B is B, the standard value range associated with the data stream B is [ B1, B2], and the Unit of the data value is Unit-2; referring to fig. 3-2, fig. 3-2 is a schematic diagram of a second display template.
The following explains and explains the data flow viewing scheme proposed in the embodiments of the present application with specific examples:
suppose there are two data streams to be viewed currently, the first data stream to be viewed is: the monitoring state since the last clearing of the failed memory, the data stream to be viewed carries sub-items: the number of emission-related fault code memory entries; the operating status of the exhaust fault indicator light; a monitored condition of the ignition misfire; monitoring status of the fuel system. The second data stream to be viewed is: engine coolant temperature, the data stream to be viewed not carrying the subentries.
The first application in the diagnosis device can transfer the configured information associated with the data streams to be viewed to the second application, wherein the information associated with the first data stream to be viewed comprises: the data stream sequence number is: 1; the data stream name is: monitoring status since the last clearing of the failed memory; the included sub-item names and the units associated with the sub-items, and the standard value ranges associated with the sub-items are respectively as follows: the number of the fault code storage items related to discharge is one, and the fault code storage items have no standard value range; secondly, the working state of the exhaust fault indicator lamp has no unit and has no standard value range; thirdly, the monitoring state of the ignition fire has no unit and standard value range; and fourthly, the monitoring state of the fuel system has no unit and standard value range. The information associated with the second stream of data to be viewed includes: the data stream sequence number is: 2; the data stream name, unit and standard value range are respectively: engine coolant temperature, degrees celsius, [ -20,120 ]. These information may be populated by the second application into corresponding first and second display templates, wherein the first display template is used to display information associated with the first stream of data to be viewed (stream of data with sub-items) and the second display template is used to display information associated with the second stream of data to be viewed (stream of data without sub-items).
The first application reads the data values of the data streams with the data stream serial numbers 1 and 2 through a preset data reading interface, and judges through the corresponding standard value range to obtain the corresponding value state. For the first data stream to be checked, the first application can read the sub-item data value of each sub-item and judge to obtain the value state of the corresponding sub-item.
