Fig. 2 is a flowchart of a comparison result display method of a data structure according to an embodiment of the present application, where the comparison result display method of the data structure is applied to a terminal for illustration, and the comparison result display method of the data structure may include the following steps:

step 201: and the terminal acquires the first version CAD data and the second version CAD data of the target automobile.

The data use time of the first version CAD data is earlier than the data use time of the second version CAD data.

Since there are multiple development processes in the development stage of the target automobile, the CAD data of the target automobile may or may not be updated in each development process. Therefore, in order to determine whether the CAD data of the target car is updated in the current development flow, the terminal can acquire the first version CAD data and the second version CAD data of the target car, or in order to determine in which flow the CAD data of the target car is updated, the first version CAD data and the second version CAD data can also be acquired.

As an example, the terminal can acquire the first version CAD data and the second version CAD data of the target car upon receiving the comparison instruction.

It should be noted that the comparison instruction is triggered when the user acts on the terminal through a specified operation, and the specified operation can be a click operation, a sliding operation, a voice operation, or the like.

In some embodiments, the terminal can obtain the first version CAD data and the second version CAD data from a stored file, or from other devices or systems.

In some embodiments, the terminal is capable of loading the first version CAD data and the second version CAD data after the first version CAD data and the second version CAD data are acquired.

Step 202: the terminal preprocesses the first version CAD data and the second version CAD data.

Since there is a large amount of information about the parts in the CAD data, at least one of deletion, addition, position change, and the like of the parts is generally generated when the CAD data is changed, it is generally necessary to pre-process the first version CAD data and the second version CAD data in order to facilitate comparison of the first version CAD data and the second version CAD data.

As an example, the operation of the terminal for preprocessing the first version CAD data and the second version CAD data at least includes: and storing the part numbers, the hierarchy information and the coordinate information of the parts in the first version CAD data and the second version CAD data into a specified file.

Since the CAD data is changed in general to at least one of the part number, the hierarchy information, and the coordinate information of the part, the terminal can store the part number, the hierarchy information, and the coordinate information of the part in the first version CAD data and the second version CAD data in a designated file.

It should be noted that, the designated file is a file indicating that the data structure is to be compared, that is, the data stored in the designated file is the data to be compared.

In some embodiments, the terminal may store the part numbers, the hierarchy information, and the coordinate information of the parts in the first version CAD data and the second version CAD data in the same file, and may also store the part numbers, the hierarchy information, and the coordinate information of the parts in the first version CAD data and the second version CAD data in two files, respectively.

In some embodiments, in order to ensure the correctness and efficiency of data comparison, before preprocessing the first version CAD data and the second version CAD data, the terminal is further capable of determining whether both the first version CAD data and the second version CAD data have been published according to the data identifier of the target car; when the first version CAD data and the second version CAD data are not released, repairing the naming of the parts in the first version CAD data and the second version CAD data; the operations of step 202 described above are performed when the first version CAD data and the second version CAD data have been published.

It should be noted that the data state identifier is used to uniquely identify the data state, and the data state identifier can be at least one of any number, letter, text, and the like.

As an example, the terminal can find out from the version release list of the target automobile whether there is a version number identical to the version number of the first version CAD data and the version number of the second version CAD data, respectively, and when there is a version number identical to the version number of the first version CAD data and the version number of the second version CAD data, respectively, determine that both the first version CAD data and the second version CAD data have been released; when the version number identical to the version number of the first version CAD data does not exist, it is determined that the first version CAD data is not released, and when the version number identical to the version number of the second version CAD data does not exist, it is determined that the second version CAD data is not released.

In some embodiments, the terminal is capable of displaying a naming repair display interface, and when the terminal receives a repair instruction based on the naming repair display interface, repairing the part names in the first version CAD data and the second version CAD data according to the part numbers and the part names carried in the repair instruction.

It should be noted that the repair instruction is triggered when the user acts on the named repair display interface through the specified operation.

In some embodiments, the terminal is further capable of receiving a selection instruction prior to preprocessing the first version CAD data and the second version CAD data, and preprocessing the data structure selected by the selection instruction in the first version CAD data and the selected data structure in the second version CAD data.

Because it may be only necessary to compare some of the CAD data of different versions of the target car, and not all of the CAD data, the terminal may also be capable of receiving the selection command and preprocessing the data structure selected by the selection command.

The selection instruction is triggered when the user acts on the first version CAD data and the second version CAD data through a specified operation.

Step 203: and the terminal compares the preprocessed first version CAD data with the preprocessed second version CAD data according to the comparison rule.

As an example, the operation of the terminal comparing the preprocessed first version CAD data with the second version CAD data according to the comparison rule at least includes: searching the second version CAD data for a reference part number which is the same as the target part number by taking the first version CAD data structure as a reference, wherein the target part number is the part number of any part in the first version CAD data; when the reference part number does not exist in the second version CAD data, performing first scene marking and first marking value marking at the position corresponding to the reference part number in the first version CAD data; and when the reference part number exists in the second version CAD data, comparing the first version CAD data with the second version CAD data according to the level information and the coordinate information of the reference part number and the level information and the coordinate information of the target part number.

Since at least one of deletion, addition, and position change of a component is generally generated when CAD data is changed, the terminal can determine whether or not there is a deletion change in the first version CAD data and the second version CAD data for comparison. I.e. the terminal can look up the same reference part number as the target part number in the second version CAD data, based on the first version CAD data structure. If the reference part number appearing in the first version CAD data cannot be found in the second version CAD data, the condition that the part is deleted in the second version CAD data is explained, so that in order to enable a user to quickly find the change condition, the terminal can perform first scene marking and first marking value marking at the position corresponding to the target part number in the first version CAD data.

It should be noted that the scene mark includes a mark scene type and a scene description, wherein the scene type of the first scene is scene 1, the scene description is that the parts in the new structure are missing, and the parts in the original structure are present, and the parts in the new structure are not present. The tag value is used to tag the type of data change, and the first tag value can be Lose.

Since the part indicated by the target part number is not absent from the second version CAD data when the reference part number is present in the second version CAD data, the terminal can continue to determine the positions of the part of the reference part number and the part of the target part number. That is, the terminal can compare the first version CAD data with the second version CAD data according to the hierarchy information and the coordinate information of the reference part number and the hierarchy information and the coordinate information of the target part number.

In some embodiments, when the reference part number exists in the second version CAD data, the operation of the terminal comparing the first version CAD data with the second version CAD data according to the hierarchy information and the coordinate information of the reference part number and the hierarchy information and the coordinate information of the target part number at least includes: determining whether the hierarchical information and the coordinate information of the reference part number are identical to the hierarchical information and the coordinate information of the target part number, respectively; when the level information of the reference part number is inconsistent with the level information of the target part number and the coordinate information of the reference part number is consistent with the coordinate information of the target part number, performing second scene marking and second marking value marking at the position corresponding to the target part number in the first version CAD data and the position corresponding to the reference part number in the second version CAD data; when the level information of the reference part number is inconsistent with the level information of the target part number and the coordinate information of the reference part number is inconsistent with the coordinate information of the target part number, performing third scene marking and third marking value marking at the position corresponding to the target part number in the first version CAD data and the position corresponding to the reference part number in the second version CAD data; when the level information of the reference part number is consistent with the level information of the target part number and the coordinate information of the reference part number is inconsistent with the coordinate information of the target part number, performing a fourth scene mark and a fourth mark value mark at a position corresponding to the target part number in the first version CAD data and a position corresponding to the reference part number in the second version CAD data; when the level information of the reference part number is consistent with the level information of the target part number and the coordinate information of the reference part number is consistent with the coordinate information of the target part number, performing fifth scene marking and fifth marking value marking at the position corresponding to the target part number in the first version CAD data and the position corresponding to the reference part number in the second version CAD data; and searching the part numbers which are not marked in the second CAD data, and marking a sixth scene mark and a sixth mark value at positions corresponding to the part numbers which are not marked in the second version CAD data.

Since there may be an error in the coordinate information for some reasons, the terminal needs to determine whether an error between the coordinate information of the reference part number and the coordinate information of the target part number is greater than a preset value when determining whether the coordinate information of the reference part number is identical to the coordinate information of the target part number, and determines that the coordinate information of the reference part number is identical to the coordinate information of the target part number when the error between the coordinate information of the reference part number and the coordinate information of the target part number is greater than the preset value, and determines that the coordinate information of the reference part number is identical to the coordinate information of the target part number when the coordinate information of the reference part number is less than or equal to the preset value.

It should be noted that the preset value can be set in advance according to the requirement, for example, the preset value can be 5mm, 6mm, and the like.

Because the new part does not exist in the first version CAD data after the new part is added in the second version CAD data, the terminal needs to search the unmarked part number in the second CAD data at the end of data comparison, and the unmarked part number is the part number of the newly added part in the second version CAD data relative to the first version CAD data.

It should be noted that, the scene type of the second scene is scene 2, the scene descriptions are identical in part number, identical in coordinates, inconsistent in hierarchy, and the second flag value can be No. The third scene is scene 3, the scene description is that the part numbers are consistent, the coordinates are inconsistent, the hierarchy is inconsistent, and the third mark value can be No. The scene type of the fourth scene is scene 4, the scene description is that the part numbers are consistent, the coordinates are inconsistent, the layers are consistent, and the fourth mark value can be No. The fifth scene is scene 5, the scene description is part number consistent, coordinates consistent, hierarchy consistent, the fifth flag value can be Yes. The scene type of the sixth scene is scene 6, the scene is described as being newly added in the New structure, that is, the original structure does not exist in the New structure, and the sixth flag value can be New.

In some embodiments, after comparing the first version CAD data with the second version CAD data, the terminal can perform not only change-related marks in the second version CAD data, but also the same marks in the first version CAD data in order to enable the user to learn about changes that occur after the first version CAD data when viewing the first version CAD data. I.e. writing all scene marks and mark values in corresponding positions of the structure files of the first version CAD data and the second version CAD data, the scene marks and mark values marks being used to represent differences between the second version CAD data and the first version CAD data.

In some embodiments, the terminal is further capable of counting the number of parts that are marked after comparing the first version CAD data with the second version CAD data. For example, the terminal can respectively count the number of parts corresponding to different marking values or the number of parts corresponding to different scene types according to the marking values or the scene types.

In some embodiments, after comparing the preprocessed first version CAD data with the second version CAD data according to the comparison rule, the terminal is further capable of storing differences between the first version CAD data and the second version CAD data in the file.

Step 304: the terminal displays a comparison result between the first version CAD data and the second version CAD data.

In some embodiments, the terminal is further capable of displaying the first version CAD data and the second version CAD data, and the changes therebetween, after comparing the preprocessed first version CAD data with the second version CAD data according to the comparison rule.

As an example, the terminal is further capable of visually displaying the comparison result on the first-version CAD data and the second-version CAD data by color identification information.

In some embodiments, the operation of the terminal to visually display the comparison result on the first version CAD data and the second version CAD data by the color identification information comprises: when the terminal receives the visual viewing instruction, displaying the first version CAD data and the second version CAD data carrying the scene mark and the mark value mark, wherein different scene marks and different mark value marks correspond to different display colors in the first version CAD data and the second version CAD data.

It should be noted that, in order to make it clear for the user to know which changes have specifically occurred between the first version CAD data and the second version CAD data, the terminal can display different scene marks and different mark value marks by different display colors. For example, the scene mark of the first scene is displayed as yellow (color is represented as 255, 0), the scene mark of the second scene is displayed as cyan (color is represented as 0, 255, 255), the scene mark of the third scene is displayed as blue (color is represented as 0, 255), the scene mark of the fourth scene is displayed as brown (color is represented as 139, 35, 35), the scene mark of the fifth scene is displayed as magenta (color is represented as 255,0, 255), and the scene mark of the sixth scene is displayed as gray (color is represented as 190, 190, 190).

In some embodiments, the terminal is further capable of displaying the differences between the first version CAD data and the second version CAD data directly by different colors.
