Description

Technical Field

[0001] This invention relates to the field of data processing, and in particular to a method, apparatus, terminal equipment, and medium for managing color difference data of passenger vehicles. Background Technology

[0002] Controlling color difference in passenger vehicles requires daily collection and analysis of color data measured by the paint shop and exterior component suppliers. Currently, this is done manually by entering data into Excel spreadsheets and sending them via email. Users need to compare and analyze color difference data for key exterior components such as the body and front and rear bumpers to determine control methods. This approach has the following problems: statistical analysis of body and exterior component data is difficult, requiring the processing of large amounts of data for each analysis, resulting in low efficiency; and the color difference data is released infrequently by the paint shop and suppliers, with suppliers only releasing data once a week, which can only be used for retrospective review and lacks timeliness.

[0003] Therefore, there is an urgent need for a management strategy for passenger vehicle color difference data to solve the problem of low processing efficiency of passenger vehicle color difference data. Summary of the Invention

[0004] This invention provides a method, apparatus, terminal equipment, and medium for managing color difference data of passenger vehicles, so as to improve the efficiency of color difference data processing for passenger vehicles.

[0005] To address the aforementioned problems, one embodiment of the present invention provides a method for managing color difference data in passenger vehicles, comprising:

[0006] Obtain color difference data for passenger vehicle components;

[0007] The color difference data is analyzed based on the preset color difference threshold range;

[0008] When the color difference data exceeds the color difference threshold range, the corresponding component coloring strategy is retrieved from the database and sent to the user so that the user can adjust the component coloring strategy.

[0009] As an improvement to the above solution, it also includes:

[0010] A number of color difference data points are aggregated, and a line chart corresponding to the component type selected by the user is generated. The color difference data includes: color difference value, component type, and date. The horizontal axis of the line chart is the date, and the vertical axis is the color difference value. The component type includes: vehicle model, angle, component category, supplier, production batch, and color.

[0014] Determine the relationship between the points corresponding to all dates on the line chart and the upper and lower threshold lines, respectively;

[0015] When the coordinate point on the line chart is greater than the upper threshold line or less than the lower threshold line, the first coloring strategy of the component corresponding to the coordinate point is retrieved from the database and sent to the user so that the user can adjust the first coloring strategy of the component.

[0016] When a coordinate point on the line chart is less than the upper threshold line but greater than the lower threshold line, the second coloring strategy for the component corresponding to the coordinate point is retained, and the second coloring strategy for the component is sent to the user so that the user can continue to use the second coloring strategy for the component.

[0017] As an improvement to the above solution, the acquisition of color difference data of passenger vehicle components specifically involves:

[0018] Obtain color data for passenger vehicle components;

[0019] Based on the color data, the vehicle model, component category, and supplier in the color data are identified and judged according to preset recognition rules;

[0020] When the vehicle model, component category, and supplier are all present, the color data will be used as the color difference data.

[0021] If one or more of the vehicle model, component category, or supplier are not present, the color data is cleared.

[0022] Accordingly, one embodiment of the present invention also provides a management device for color difference data of passenger vehicles, including: a data acquisition module, a data analysis module, and a control module;

[0023] The data acquisition module is used to acquire color difference data of passenger vehicle components;

[0024] The data analysis module is used to analyze color difference data according to a preset color difference threshold range;

[0025] The control module is used to retrieve the corresponding component coloring strategy from the database when the color difference data exceeds the color difference threshold range, and send the component coloring strategy to the user so that the user can adjust the component coloring strategy.

[0026] As an improvement to the above solution, it also includes: a line graph module; the line graph module includes: a first image generation unit, a second image generation unit, and an image analysis unit;

[0027] The first image generation unit is used to summarize several color difference data and generate a line chart corresponding to the component type selected by the user; wherein, the color difference data includes: color difference value, component type and date; the horizontal axis of the line chart is the date and the vertical axis is the color difference value; and the component type includes: vehicle model, angle, component category, supplier, production batch and color;

[0028] The second image generation unit is used to generate an upper threshold line and a lower threshold line in a line graph corresponding to the component type, based on the color difference threshold range corresponding to the component type selected by the user; wherein, the color difference threshold range includes an upper color difference threshold and a lower color difference threshold; and the vertical coordinate value of the upper threshold line corresponds to the upper color difference threshold, and the vertical coordinate value of the lower color difference threshold corresponds to the lower color difference threshold.

[0029] The image analysis unit is used to analyze color difference data based on the line graph, the upper threshold line, and the lower threshold line.

[0030] As an improvement to the above solution, the analysis of color difference data based on the line chart, the upper threshold line, and the lower threshold line specifically involves:

[0031] Determine the relationship between the points corresponding to all dates on the line chart and the upper and lower threshold lines, respectively;

[0032] When the coordinate point on the line chart is greater than the upper threshold line or less than the lower threshold line, the first coloring strategy of the component corresponding to the coordinate point is retrieved from the database and sent to the user so that the user can adjust the first coloring strategy of the component.

[0033] When a coordinate point on the line chart is less than the upper threshold line but greater than the lower threshold line, the second coloring strategy for the component corresponding to the coordinate point is retained, and the second coloring strategy for the component is sent to the user so that the user can continue to use the second coloring strategy for the component.

[0034] As an improvement to the above solution, the data acquisition module includes: a color data acquisition unit, a data recognition unit, a first recognition result unit, and a second recognition result unit;

[0035] The color data acquisition unit is used to acquire color data of passenger vehicle components;

[0036] The data recognition unit is used to identify and determine the vehicle model, component category, and supplier in the color data according to the color data and through preset recognition rules.

[0037] The first identification result unit is used to treat the color data as color difference data when the vehicle model, component category, and supplier are all present.

[0038] The second identification result unit is used to clear the color data if one or more of the vehicle model, component category, or supplier are not present.

[0039] Accordingly, one embodiment of the present invention also provides a computer terminal device, including a processor, a memory, and a computer program stored in the memory and configured to be executed by the processor, wherein the processor executes the computer program to implement a method for managing color difference data of passenger vehicles as described in the present invention.

[0042] This invention provides a method for managing color difference data in passenger vehicles. By judging the color difference threshold range of the color difference data for each passenger vehicle component, it can promptly analyze whether the color difference data exceeds the threshold range.

This avoids manual interpretation and comparison of color difference data, improves the processing efficiency of color difference data, and enables users to quickly judge color differences according to this invention. It is beneficial to remind automakers to adjust the coloring strategy of passenger vehicle components with color difference problems in a timely manner, thus speeding up the vehicle processing flow.

[0043] Furthermore, this invention summarizes color difference data and generates line charts based on the component types of the color difference data. The line charts are then used to analyze the color difference data and determine the color difference threshold range for multiple sets of color difference data with the same component type, thereby further improving the processing efficiency of color difference data. This invention also allows users to generate different line charts based on different component types, thus meeting the needs of complex and ever-changing actual business scenarios.

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] Example 1

[0053] See Figure 1 , Figure 1 This is a flowchart illustrating a method for managing color difference data in passenger vehicles according to an embodiment of the present invention. Figure 1 As shown, this embodiment includes steps 101 to 103, and the specific steps are as follows:

[0054] Step 101: Obtain color difference data of passenger vehicle components.

[0055] In one specific embodiment, for a better illustration of color difference data, please refer to [link to relevant documentation]. Figure 3 A set of color difference data includes: the corresponding vehicle model ( Figure 3 MODEL in the middle), Component Category 1 ( Figure 3 SORT (component mounting location) and color ( Figure 3 COKOR in the middle), Component Category Two ( Figure 3In this context, dSZM refers to the component mounting position and angle. Figure 3 ANGLE in the middle), component category three ( Figure 3 PARAM (parameter name) and its supplier ( Figure 3 SUPPLIER in the middle), date ( Figure 3 SC_RQ in the production batch ( Figure 3 BATCH in the image) and color difference value ( Figure 3 The data consists of DOT_01 to DOT_07, which are the color difference values ​​of the seven detection points; each item in the color difference data can be stored as 50 bytes.

[0056] In this embodiment, obtaining the color difference data of the passenger vehicle components specifically involves:

[0057] Obtain color data for passenger vehicle components;

[0058] Based on the color data, the vehicle model, component category, and supplier in the color data are identified and judged according to preset recognition rules;

[0059] When the vehicle model, component category, and supplier are all present, the color data will be used as the color difference data.

[0060] If one or more of the vehicle model, component category, or supplier are not present, the color data is cleared.

[0061] In one specific embodiment, the painting workshop and the exterior parts supplier export color data using a colorimeter. Based on preset recognition rules, they determine whether the color data conforms to the processing specifications. The preset recognition rules are as follows:

[0062] Step 401: Obtain color data;

[0063] Step 402: Detect the vehicle model that is present in the color data;

[0064] Step 403: Match the component category of the color data according to the vehicle model;

[0065] Step 404: Detect the presence of component categories corresponding to the vehicle model in the color data;

[0066] Step 405: Match the supplier of color data according to vehicle model and component type;

[0067] Step 406: Detect the supplier corresponding to the vehicle model component category in the color data;

[0068] Step 407: Obtain color difference data and store it in the database for the color difference administrator to call upon the customized color difference comparison chart.

[0069] In a specific embodiment, before obtaining the color difference data in step 407, the method further includes: identifying the number of color difference value data corresponding to the measurement points of the color data; when the number is greater than the preset number of identification measurement points, the redundant color difference value data is cleared (e.g., if there are 9 color difference value data, but the preset identification measurement points are only Dot_1 to Dot_7, i.e., 7 measurement points, then the last 2 color difference value data are cleared); when the number is less than the preset number of identification measurement points, the color difference value data that cannot be obtained is set to empty (e.g., if there are 6 color difference value data, but the preset identification measurement points are only Dot_1 to Dot_7, i.e., 7 measurement points, then Dot_7 is empty).

[0070] Step 102: Analyze the color difference data according to the preset color difference threshold range.

[0071] In this embodiment, users can customize view filtering, and can perform custom filtering based on the vehicle model, date, and color. After completing the aforementioned operations, the color difference data of each vehicle model's components at multiple measurement points over a period of time at 15°, 25°, 45°, 75°, and 115° can be directly generated, satisfying users' needs to obtain the color difference differences of a certain vehicle model at different dates and different measurement points for the first, middle, and last components. At the same time, users can also add production batch and supplier to the color difference data.

[0072] In one specific embodiment, the color difference range threshold is based on the user's standard color data range for each component of each vehicle model at each angle.

[0073] Step 103: When the color difference data exceeds the color difference threshold range, retrieve the corresponding component coloring strategy from the database and send the component coloring strategy to the user so that the user can adjust the component coloring strategy.

[0074] In this embodiment, it also includes:

[0075] A number of color difference data points are aggregated, and a line chart corresponding to the component type selected by the user is generated. The color difference data includes: color difference value, component type, and date. The horizontal axis of the line chart is the date, and the vertical axis is the color difference value. The component type includes: vehicle model, angle, component category, supplier, production batch, and color.

[0076] Based on the color difference threshold range corresponding to the component type selected by the user, an upper threshold line and a lower threshold line are generated in the line chart corresponding to the component type; wherein, the color difference threshold range includes an upper color difference threshold and a lower color difference threshold; and the vertical axis value of the upper threshold line corresponds to the upper color difference threshold, and the vertical axis value of the lower color difference threshold corresponds to the lower color difference threshold.

[0077] The color difference data is analyzed based on the line graph, the upper threshold line, and the lower threshold line.

[0078] In this embodiment, the analysis of color difference data based on the line chart, the upper threshold line, and the lower threshold line specifically involves:

[0079] Determine the relationship between the points corresponding to all dates on the line chart and the upper and lower threshold lines, respectively;

[0080] When the coordinate point on the line chart is greater than the upper threshold line or less than the lower threshold line, the first coloring strategy of the component corresponding to the coordinate point is retrieved from the database and sent to the user so that the user can adjust the first coloring strategy of the component.

[0081] When a coordinate point on the line chart is less than the upper threshold line but greater than the lower threshold line, the second coloring strategy for the component corresponding to the coordinate point is retained, and the second coloring strategy for the component is sent to the user so that the user can continue to use the second coloring strategy for the component.

[0082] In one specific embodiment, for better illustration, please refer to [link to specific embodiment]. Figure 5 , Figure 6 ;like Figure 5 As shown, the upper right corner shows the parameter name and angle of the passenger vehicle component corresponding to Δa25°. The X-axis represents the date, and the Y-axis represents the color difference value. Different colors are used to distinguish different lines from top to bottom. The naming format of the lower line is the component type (supplier). The two parallel lines with the maximum and minimum values ​​are the color difference data control values ​​set by the color difference administrator in the standard data table. It can be seen intuitively whether the color difference data provided by the supplier meets the control standard (if the color difference value is within the set maximum and minimum control range, it meets the requirements; otherwise, it does not meet the requirements).

[0083] like Figure 6 As shown, the upper right corner displays the parameter name and angle of the passenger vehicle component corresponding to Δb 25°. Yuxin Fang Sheng provided the component category as rear-end data. After issues arose on January 6th, effective measures were taken, resulting in normal color difference data on the 8th. However, due to inadequate management after the 8th, data deviations from control reappeared. Based on this chart, a special meeting of the interior and exterior trim departments was held to discuss and analyze the situation, and effective measures were formulated. Finally, after three serious deviations from control, the color difference value was brought back to the normal range on January 21st. The above example illustrates one beneficial effect. Furthermore, color difference administrators can use the fluctuations in the line graph to judge the trend of color difference changes, thus preventing substandard color difference values ​​before key milestones.

[0084] In one specific embodiment, to effectively manage the color difference issue across the entire vehicle, the Information and Process Department needs to compare and analyze the color difference data of key exterior components such as the body and front and rear bumpers daily to determine control methods. The statistical data needs to include 14 colors such as Starry White and Jade Green, and the daily production sampling data analysis of exterior components for the body and front and rear bumpers of 8 model series including M4, SX5G, and Lingzhi. Assuming an average daily production of 5 models and 6 colors, with each model color requiring statistical analysis involving 3 components (body, front, and rear bumpers), and assuming a 3-minute data processing time per component color for each model, the daily data processing time is: 5 * 6 * 3 * 10 / 60 = 4.5 hours. Based on 250 production days per year, after the system goes live, the annual time saved in color difference data processing is: 250 * 4.5 = 1125 hours, significantly reducing the company's operating costs.

[0085] This embodiment determines the color difference threshold range for each passenger vehicle component's color difference data. It can promptly analyze whether the color difference data exceeds the threshold range, and when it does, it retrieves the corresponding component coloring strategy, allowing users to adjust it. Users can customize view filters based on date, control elements, vehicle model, and color. By controlling supplier and factory data entry, automatically generating trend charts and controlling upper and lower limits, and allowing for customized view filtering, this embodiment flexibly meets the needs of complex and ever-changing business scenarios. Compared to manual statistical analysis of color difference data, this embodiment significantly reduces processing time and improves the efficiency of passenger vehicle color difference data management.

[0097] When the coordinate point on the line chart is greater than the upper threshold line or less than the lower threshold line, the first coloring strategy of the component corresponding to the coordinate point is retrieved from the database and sent to the user so that the user can adjust the first coloring strategy of the component.

[0098] When a coordinate point on the line chart is less than the upper threshold line but greater than the lower threshold line, the second coloring strategy for the component corresponding to the coordinate point is retained, and the second coloring strategy for the component is sent to the user so that the user can continue to use the second coloring strategy for the component.

[0103] The first identification result unit is used to clear the color data when one or more of the following are not present: the vehicle model, angle, component category, supplier, production batch, or color.

[0104] This embodiment acquires color difference data of passenger vehicle components through a data acquisition module, then inputs the color difference data into a data analysis module for analysis. The control module then retrieves the component coloring strategy based on the analysis results, transmits it, and sends it to the user so that the user can adjust the component coloring strategy. This embodiment avoids manual interpretation and comparison of color difference data, improving the processing efficiency of color difference data.
