[0054] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0055] As the quality of modern life improves, the pursuit of personalization is also budding in the minds of users. More and more customers will customize a car that suits their own preferences. Therefore, various automobile OEMs will launch a variety of configurations for customers to choose from. However, with the increase in automobile interior and exterior configurations, the types have also become more and more diverse, and the vehicle configurations in the vehicle bill of materials (BOM) system have also increased. In the automobile assembly production line, especially in the production line of the general assembly workshop, due to the high similarity of spare parts, it is easy to have the problem of wrong installation or even missing installation. Therefore, it is necessary to detect the wrong or missing installation of parts.

[0056] Currently, commonly used inspection technologies include manual configuration list inspection. As mentioned above, due to the large amount of content in the bill of materials and the messy content, the inspection efficiency is low, and it is highly dependent on manual work, with a high probability of error. To solve these problems, this application proposes a method for inspecting the component feature items of a vehicle. First, the commonly used terms in this application are explained as follows:

[0057] The material system can be a BOM system, which is a detailed list reflecting the complete component structure information of the product. It can fully describe the design composition or assembly relationship of a product, including the structure, component code, quantity, use conditions and other information of the components. To configure the BOM of a vehicle, you need to select from the many configuration options (parameters) of the product data management system within the pre-set production range according to the configuration requirements of the actual production model. Each configuration information is associated with a specific component. After the selection is completed, the vehicle BOM corresponding to the actual required model can be obtained;

[0058] Manufacturing execution system (MES) is a production information management system for the execution layer of the workshop of manufacturing enterprises. MES can provide enterprises with management modules including manufacturing data management, planning and scheduling management, production scheduling management, inventory management, quality management, human resources management, equipment management, tooling management, procurement management, cost management, project kanban management, production process control, bottom-level data integration analysis, and upper-level data integration decomposition, creating a solid, reliable, comprehensive and feasible manufacturing collaborative management platform for enterprises.

[0059] The variation rule highlights the essential characteristics of things and those hidden essential elements by changing the expression forms of non-essential characteristics of similar things and changing the angle and method of observing things.

[0060] In one embodiment, Figure 1 As shown, a method for checking the characteristic items of vehicle components is provided. This embodiment takes the method applied to a characteristic management system as an example. The characteristic management system may specifically be an MES. In this embodiment, the method includes the following steps:

[0061] Step 102: receiving an assembly inspection instruction of a vehicle sent by a terminal, wherein the assembly inspection instruction includes a vehicle identification;

[0062] In this embodiment, the terminal may be a portable Android device, which scans a vehicle identification on the vehicle, generates an assembly inspection instruction based on the vehicle identification, and sends the assembly inspection instruction to the MES. The vehicle identification may be a vehicle identification number (VIN).

[0063] Step 104: based on the vehicle identification, the bill of materials of the vehicle is obtained from the material system, the bill of materials is matched with the feature set of all pre-stored component feature items, matching feature items matching the bill of materials are determined, and feature subsets matching the bill of materials are determined from the feature set of each matching feature item; the feature set of each component feature item includes features obtained by extracting features from the bill of materials of all vehicles after the feature management system obtains the bill of materials of all vehicles from the material system;

[0064] The MES maintains feature sets of multiple component feature items in advance. The component feature items include the component itself and / or the attributes of the component. Specifically, the vehicle's interior components, exterior components, chassis, regulatory labels and other components themselves can be used as component feature items, for example, "trunk shelf", "luggage rack", or "brake warning label" and other components themselves can be used as component feature items; the attributes of the vehicle's interior components, exterior components, chassis, regulatory labels and other components can also be used as component feature items, for example, "exterior mirror cover color" or "tire specifications" can be used as component feature items.

[0065] Each component feature item is correspondingly maintained with a feature set, each feature set includes one or more feature subsets, each feature subset is correspondingly matched to a feature image, and different feature subsets are matched to different feature images.

[0066] For each component feature item, the feature management system obtains the bills of materials of all vehicles from the material system, then obtains the bills of materials related to the current component feature item from the bills of materials of each vehicle, performs feature extraction on the bills of materials related to the current component feature item, and obtains the feature subset corresponding to the bill of materials of the vehicle, and integrates the feature subsets corresponding to the bills of materials of all vehicles to obtain the feature set of the current component feature item.

[0067] Step 106: Send the feature subset of the matching feature item to the terminal so that the terminal can display the feature subset and receive the inspection result obtained by the user after performing assembly inspection on the matching feature item based on the displayed feature subset.

[0068] The feature subsets corresponding to the matching feature items are sent to the terminal, and the terminal can display the feature subsets. The user performs assembly inspection on the corresponding matching feature items based on the feature subsets displayed by the terminal, obtains the inspection results, and inputs the inspection results on the terminal. In this way, the user can check the matching feature items one by one and input the inspection results of each matching feature item.

[0069] In this embodiment, an assembly inspection instruction of a vehicle sent by a receiving terminal is received, and the assembly inspection instruction includes a vehicle identification, so that the bill of materials of the vehicle is obtained from the material system based on the vehicle identification, and the bill of materials is matched with a feature set of all pre-stored component feature items to determine matching feature items that match the bill of materials, and a feature subset that matches the bill of materials is determined from the feature set of each matching feature item, so that matching feature items corresponding to each vehicle and feature subsets of matching feature items can be obtained, so that the feature subsets of matching feature items are sent to the terminal so that the terminal can display the feature subsets, and then the inspection results obtained after the user performs an assembly inspection on the matching feature items based on the displayed feature subsets are received, thereby realizing assembly inspection of the matching feature items of each vehicle. The present application predefines component feature items, and then obtains the bill of materials of all vehicles from the material system, and then extracts features from the bill of materials of all vehicles to construct a feature set of each component feature item. In this way, the feature sets of the component feature items that need to be checked are sorted, and then the feature subsets of matching feature items are obtained from the feature sets of all component feature items, and assembly inspection is performed on the matching feature items of the vehicle. Compared with directly assembling the vehicle based on the bill of materials, this avoids the situation where the inspection content is too much and messy, and improves the inspection efficiency. At the same time, manual configuration inspection is based on the feature subset sorted for the matching feature items, rather than directly assembling the vehicle based on the bill of materials, which reduces the probability of error.

[0070] In one of the embodiments, the method also includes: obtaining a pre-stored feature image that matches the feature subset; and correspondingly sending the feature subset of the matching feature item to the terminal, including: sending the feature subset and the feature image of the matching feature item to the terminal so that the terminal displays the feature subset and the feature image, and receiving the inspection result obtained by the user after the assembly inspection of the matching feature item is performed based on the displayed feature subset and feature image.

[0071] For each component feature item, each feature subset of the component feature item has a matching feature image, which is maintained in the MES system by the user in advance. The feature images of each feature subset are different, which means that for the same component feature item, the feature images matched to the bill of materials of different vehicles may be different.

[0072] The feature picture is the picture of the component corresponding to each component feature item. The picture can intuitively reflect the specific situation of each component feature item. For example, if the component feature item is "trunk shelf", then the feature picture is the picture of the trunk shelf. If the component feature item is "color of the exterior rearview mirror cover", the feature picture is the picture of the exterior rearview mirror cover, and the picture of the exterior rearview mirror cover should clearly reflect the color of the exterior rearview mirror cover.

[0073] When sending the feature subset corresponding to the matching feature item to the terminal, it is also necessary to send the feature image matching the feature subset to the terminal;

[0074] The specific manner in which the terminal displays the feature subset and the feature image is as follows: the terminal displays the feature subsets of the component feature items and the corresponding feature images in sequence according to the preset display order of the component feature items, and the user performs assembly inspection on each matching feature item based on the feature subset and the corresponding feature image of each matching feature item, and inputs the inspection result in the terminal. The specific display manner will be described in the following embodiments.

[0075] In this embodiment, MES not only sends a feature subset that matches the feature item to the terminal, but also sends a feature picture to the terminal so that the terminal can display the feature picture, so that the user can more intuitively detect whether there is an assembly error in the component feature item based on the displayed feature picture.

[0076] The following is a detailed description of this application plan:

[0077] 1. Hardware:

[0078] See also Figure 2 The diagram of the interaction between the terminal and MES is shown in the figure. The terminal can be a tablet computer (PAD). The BOM system of each vehicle is timely associated with the feature item configuration module of MES, and the MES feature site configuration of the MES management end is performed. The feature item query module of MES is associated with the tablet configuration system of the tablet computer (corresponding to the workplace feature inspection interface in the figure), and the MES custom feature inspection of the MES management end is performed. The defect entry module of MES is associated with the tablet configuration system, and the MES defect entry of the MES management end is performed. Through these three associations, the PAD can realize the configuration inspection of each vehicle, and when a vehicle with a configuration error is found, the information can be transmitted in time through the defect entry module in MES. Considering the compatibility with MES, an Android tablet computer can be selected. In addition, the tablet computer is relatively portable, which is convenient for confirming the configuration information of the vehicle at multiple locations. It is used to perform multi-station inspection of the configuration information to prevent the missed inspection of the wrong installation problem caused by human factors.

[0079] As shown in the figure, the workplace feature check interface displays the feature code, feature name, corresponding value, and feature image. After the user performs the configuration check, he can select wrong installation, missing installation, or OK.

[0080] 2. Software:

[0081] It mainly realizes the one-to-one correspondence between the feature item configuration module of MES and BOM, and the association between the MES defect entry system and the flat panel configuration inspection system. It ensures the uniqueness and accuracy of each order and ensures that the vehicle configuration is consistent with the configuration in BOM and MES.

[0082] As mentioned above, the present application defines component feature items, and maintains a feature set of component feature items in the MES system in advance. The following is a detailed description of the method for maintaining the feature set of component feature items in the MES system:

[0083] In one of the embodiments, the method further includes: after obtaining the bill of materials of all vehicles from the material system, obtaining the basic component features of each component feature item from the bill of materials of all vehicles; configuring the extended component features of each component feature item in the sub-feature items of the basic component features; and obtaining the feature set of each component feature item based on the basic component features of each component feature item and the corresponding extended component features.

[0084] The basic component features include features extracted from the bill of materials and at least one of the first custom features. The features extracted from the bill of materials include features directly obtained from the bill of materials and / or features obtained by integrating features based on the bill of materials. The first custom feature refers to a feature that cannot be extracted from the bill of materials and is customized by the user.

[0085] For each component feature item, after obtaining the bill of materials of each vehicle from the material system, the basic component feature of the current component feature item is obtained from the bill of materials of each vehicle, and the basic component features corresponding to the bill of materials of each vehicle are integrated to obtain the basic component feature corresponding to the current component feature item;

[0086] For each component feature item, the basic component feature is taken as the parent feature, and the extended component feature corresponding to each vehicle is further configured in the sub-feature item of the parent feature. Different vehicles may have the same parent feature (i.e., the basic component feature), but the extended component features in the sub-feature item of the parent feature are different. The basic component feature and the extended component feature corresponding to each vehicle are taken together as the feature subsets matched by the logistics lists of each vehicle. Based on the feature subsets matched by the logistics lists of each vehicle, the feature set corresponding to the current component feature item is obtained.

[0087] In the above embodiment, determining the feature subset that matches the bill of materials from the feature set of each matching feature item includes: matching multiple feature subsets in the feature set of each matching feature item with the bill of materials respectively. It should be noted that it is not necessary for all features in the feature subset to match the bill of materials before the feature subset is considered to match the bill of materials. Only some features (for example, features directly obtained from the bill of materials during the MES configuration phase, or features generated based on the bill of materials) need to match the bill of materials, and some features (for example, some features customized during the MES configuration phase) do not need to match the bill of materials. As long as the partial features match the bill of materials successfully, the entire feature subset will be used as the feature subset that matches the bill of materials, and all features in the feature subset will be fed back to the terminal for configuration checking.

[0088] Reference Figure 3 and Figure 4 , for the configuration of basic component features, a possible scenario of this implementation is as follows:

[0089] The information required for the basic component features of the MES system to create component feature items is as follows: Figure 3 As shown, the field names are: serial number, feature code, feature name, feature quantity, feature position, feature variant, creator, creation time, modifier, modification time, and the types are: integer (integer, int), variable length character type (varchar), and date and time (datetime). The field description of the serial number field is: automatically generate serial number, delete and add, the serial number is automatically updated; the field description of the feature code is: automatically generate, the default rule is: ZDYTZ+year+four-digit serial number; the field description of the feature name is: enter a description, and it is a required item; the field description of the feature quantity is: required; the field description of the feature position is: enter the location of the feature; the field description of the feature variant is: the rule that the feature needs to check to meet; the field description of the creator is: the creator's account; the field description of the creation time is: displayed in the format of "year-month-day, hour-minute-second"; the field description of the modifier is: the modifier's account; the field description of the modification time is: displayed in the format of "year-month-day, hour-minute-second". The operations include: add, edit, details, delete and export. The field description of the add operation is: add a new feature, and a new dialog box pops up; the field description of the edit operation is: when the feature number and feature name are unchanged, modify or update other fields; the field description of the details operation is: view the maintenance information of this feature (that is, the above-mentioned component feature item), and no information can be modified; the field description of the delete operation is: delete the data and prompt for confirmation; the field description of the export operation is: check the data export.

[0090] Create as Figure 3 The basic component feature information required for the component feature item shown is obtained through Figure 4Interface configuration implementation.

[0091] Select the custom feature check in the MES system, select the Add button in the custom feature check, automatically generate a serial number, and configure the basic component features. The basic component features include: feature number, feature name, feature position, feature quantity, feature variant, effective status, creator, creation time, modifier, and modification time. The creator, creation time, modifier, and modification time are automatically generated.

[0092] The feature number is ZDYTZ2023002, the feature name is B-pillar nameplate, the feature position is the lower part of the left and right B-pillars, the feature quantity is 1, the feature variant is AA00=AA31, AA32, and the effective state is yes; the feature number is ZDYTZ2023003, the feature name is trunk shelf, the feature position is trunk, the feature quantity is 1, the feature variant is AA00=AA31, AA32, and the effective state is yes; the feature number is ADYTZ0004, the feature name is front vehicle logo, the feature position is front bumper, the feature quantity is 1, the feature variant is AA00=AA31, AA32, and the effective state is yes; the feature number is ADY TZ0005, feature name is front cabin operation warning sign, feature location cabin beautification board, feature quantity is 1, feature variant is AA00=AA31, AA32, effective status is yes; feature number is ADYTZ0006, feature name is charcoal bag, feature location front and rear guard, feature quantity is 1, feature variant is AA00=AA31, AA32, effective status is yes; feature number is ADYTZ0007, feature name is welcome pedal, feature location four door thresholds, feature quantity is 4, feature variant is AA00=AA31, AA32, effective status is yes; creator and creation time are automatically generated according to the configuration person and configuration time. After configuration is completed, it supports query or search according to feature number, feature name and effective status, and then modify the feature to automatically generate the modifier and modification time. The creator and modifier are "xx", the creation time is yy1 to yy6, and the modification time is kk1 to kk6.

[0093] In the above embodiment, for a certain component feature item, in order to distinguish different vehicle models, different vehicle models can be matched by changing the feature variant to AA00 and taking different values.

[0094] In this embodiment, a method of constructing a feature set of each component feature item is described in detail. The present application predefines the component feature items in the MES system, and then maintains the corresponding feature set for each component feature item, so that the MES can directly obtain the feature subset of the matching feature items that match the vehicle's bill of materials and send it to the terminal for display, and perform assembly inspection of the vehicle's component feature items, thereby avoiding the situation where the data is large and cluttered due to the direct assembly inspection based on the vehicle's bill of materials.

[0095] As mentioned above, you can configure the extended component features of the current component feature item in the sub-feature item of the basic component feature. The extension of component features mainly includes two aspects, one is the feature image configuration, and the other is the configuration of the feature inspection part. The following will explain these two aspects separately:

[0096] In one of the embodiments, in the sub-feature items of the basic component features, the extended component features of each component feature item are configured, including: in the sub-feature items of the basic component features, a custom description feature of each component feature item, a feature image matching the basic component feature and the custom description feature, or at least one of the component features of multiple components corresponding to each component feature item are configured.

[0097] In the first sub-feature item (i.e., feature picture configuration item) of the basic component feature of each vehicle, the first extended feature and the feature picture corresponding to the first extended feature are configured. For the component feature items with associated parts, the second extended feature can be configured in the second sub-feature item (i.e., feature associated part configuration item) of the basic component feature of each vehicle, and the basic component feature, the first extended feature, and the feature picture of each vehicle are used as the feature subset matching the bill of materials of the vehicle. If the component feature item has associated parts, the basic component feature, the first extended feature, the feature picture, and the second extended feature of each vehicle are used as the feature subset matching the bill of materials of the vehicle.

[0098] Specifically, for the feature image configuration: in the first sub-feature item of the basic component feature of each vehicle, a first extended feature is configured, the first extended feature includes a second custom description feature of each vehicle, and / or an extracted feature extracted from the bill of materials of the vehicle, the second custom description feature is different from the above-mentioned first custom description feature, and the extracted feature extracted from the bill of materials is also different from the above-mentioned basic component feature extracted from the bill of materials.

[0099] In the first sub-feature item of the basic component feature, feature images that match the first extended features of the above-mentioned vehicles are configured. If the vehicle's bill of materials matches a basic component feature and a first extended feature in the sub-feature item of the basic component feature, the terminal can obtain and display the basic component feature, the first extended feature and the corresponding feature image.

[0100] For the configuration of feature-related parts: the current component feature item may exist in multiple parts of the vehicle, so in the second sub-feature item of the basic component feature, the component features of multiple components with the current component feature item are configured. The component features include component number, part description, severity, responsible party, matching strategy and matching value.

[0101] In this embodiment, a possible implementation is: feature variants can be defined in the basic component features, and for the component features of each component, the component features include a matching strategy and a matching value, and the matching strategy is set to match by variant and set the corresponding matching value, or the matching strategy is set to match by feature universal and set the corresponding matching value. Matching by variant means matching the feature variant with the vehicle's bill of materials. If the match is successful, the MES system will feedback the component features of the component to the terminal. Universal matching by feature means that the component features of the component are universal for all vehicles. Even if the vehicle's bill of materials cannot match the feature variant, the MES system will feedback the component features of the component to the terminal.

[0102] Reference Figure 5 , the application scenarios of this solution are described as follows:

[0103] The editing interface includes basic component features (basic component features are Figure 3 The interface is configured as shown): custom feature number, feature name, name of the feature location, feature quantity and feature variant. Custom feature number is automatically generated, with the generation rule of ZDYTZ+year+four-digit serial number, and feature variant is used to match the corresponding vehicle;

[0104] The extended component features include feature picture configuration and feature-related parts. In the feature picture configuration interface, multiple rows of first extended features are configured. Each row of first extended features includes a work center, a corresponding vehicle model item, and a feature picture corresponding to each row of first extended features. Feature pictures can be uploaded through the "Select Picture" button. Feature picture verification data is maintained for integrity. Feature pictures must maintain work centers and pictures.

[0105] As shown in the figure, the work center of the extended component feature in the first row is final assembly, and all are selected for the vehicle model item. For a component feature item, if the material information of the vehicle matches the basic component feature of the current component feature item and the first extended feature of a row, the basic component feature, the extended component feature of the row, and the feature image are returned to the terminal as a feature subset that matches the bill of materials, so that the terminal can check the component feature item based on the returned information.

[0106] Configuration of feature-related parts: Select the part from the MES part master data table, and select the severity drop-down value from the MES severity table; according to the Audit review standard, the severity level of the problem of wrong or missing installation is not less than A100, and the severity level of the problem of wrong or missing installation of the configuration of the regulatory item label is S300. Select the responsible party from the MES responsible party table. The matching strategy of the part can be based on variants or feature general;

[0107] For example, if the current component feature item is seat belt, and the vehicle has four seat belts, then the component features of these four seat belts need to be configured, and the component numbers of these four seat belts are configured respectively. The part descriptions of the four seat belts are rear right seat belt, rear left seat belt, front right seat belt, and front left seat belt, and the severity level, responsible party, matching strategy, and matching value of the four seat belts when the wrong or missing installation problem is configured. As shown in the figure, the part number is EPYCZYAQD, the part description is front right seat belt, the severity is A100, the responsible party is the general assembly, the matching strategy is to match according to the feature variant, and the matching value is GM00=GM01; the part number is EPZCZYAQD, the part description is rear left seat belt, the severity is A100, the responsible party is the general assembly, the matching strategy is feature general, and the matching value is GM00=GM01. The severity selections include S300, A100, B50, and C30, which respectively represent the severity levels when there are wrong or missing installations of the component feature items.

[0108] If the matching strategy corresponding to EPYCZYAQD is set to match according to feature variants, then when the vehicle bill of materials matches the feature variant "MA00=MA31" (some vehicles do not have parts numbered EPYCZYAQD, so they cannot be matched), MES will feed back the component features of the row corresponding to EPYCZYAQD to the terminal as a feature subset of the current feature item that matches the vehicle bill of materials.

[0109] If the matching strategy corresponding to EPZCZYAQD is set to general matching according to features, the vehicle bill of materials does not need to match the feature variant "MA00=MA31", and MES will feed back the component features of the row corresponding to EPZCZYAQD to the terminal as a feature subset of the current feature item matched with the vehicle bill of materials.

[0110] It can be seen that the present application provides a detailed description of the configuration of the extended component features. In the MES, not only the first extended feature and the feature image corresponding to the first extended feature are maintained, but also the associated components of the component feature items are taken into account, and the component features of the associated components of the component feature items are maintained, so as to be fed back to the terminal, so that the terminal can check the component feature items of each associated component, thereby avoiding missed detection. For example, in the above scenario, it can be clearly known that the seat belt feature item has associated associated components: the rear right seat belt, the rear left seat belt, the front right seat belt, and the front left seat belt, etc., so these four seat belts can be checked to avoid missed detection.

[0111] In one of the embodiments, in the sub-feature items of the basic component features, the extended component features of each component feature item are configured, and also include: in the sub-feature items of the basic component features, the variant component features of each component feature item are configured, and the variant component features are related to the vehicle's bill of materials; accordingly, feature images that match the basic component features and the custom description features are configured, including: configuring feature images that match the basic component features, the custom description features, and the variant component features.

[0112] The first extended feature may also include a variant component feature. The variant component feature of the component feature item may be configured in the first sub-feature item of the basic component feature. The variant component feature is used to define the variant conditions that the vehicle logistics list needs to match. The variant component feature takes different feature values ​​corresponding to different vehicle material lists.

[0113] The feature image is matched with the basic component features and the first extended features (as mentioned above, including custom description features and / or extraction features and variant component features). If the vehicle bill of materials matches the basic component features and the first extended features, the basic component features, the first extended features and the feature image are fed back to the terminal for display to perform assembly inspection of the component feature items.

[0114] See also Figure 6 ,One scenario of the present application is: for the B-pillar nameplate feature item, the basic component feature is configured as follows: the custom feature number is ZDYTZ20230002, the feature name is B-pillar nameplate, the feature location name is the lower part of the left and right B-pillars, the feature quantity is 1, and the feature variant is AA00=AA32, AA31, where AA32 and AA31 represent different models respectively;

[0115] Configure the work center and variant conditions (i.e., the variant component features mentioned above) in the feature image configuration. You can select different work centers in the drop-down options of the work center. For example, you can select the work center as Wuhan Geely Factory and configure different feature values ​​of the variant conditions. MA00 can be configured as MA10, MA39, or MA01, AB00 can be configured as AB01, and AA00 can be configured as AA32. Different variant conditions represent different origins. The work center of each row in the feature image configuration and different feature values ​​of the variant conditions correspond to different feature images. If the vehicle's bill of materials matches the basic component features, the work center of a row, and the variant conditions, the basic component features, the work center of the row, the variant conditions of the row, and the picture features corresponding to the work center and the variant conditions of the row are fed back to the terminal for display for assembly inspection.

[0116] It can be seen that a certain component feature item is different on different vehicles. The present application defines different variant conditions in the first extended feature to match different vehicle logistics lists, so that each vehicle logistics list can find the matching first extended feature and the matching feature picture for display, so as to accurately find the features of the component feature item corresponding to a certain vehicle to check the component feature item.

[0117] The above example uses the application of the assembly error checking method of vehicle parts to MES as an example. The following example uses the application of the assembly error checking method of vehicle parts to the terminal as an example. Figure 7 , the method comprises the following steps:

[0118] Step 702: Send an assembly check instruction to the feature configuration system, wherein the assembly check instruction includes a vehicle identification, so that the feature configuration system obtains the bill of materials of the vehicle from the material system based on the vehicle identification, matches the bill of materials with the feature set of all pre-stored component feature items, determines matching feature items that match the bill of materials, and determines a feature subset that matches the bill of materials from the feature set of each matching feature item; the feature set of each component feature item includes features obtained by extracting features from the bill of materials of all vehicles after the feature management system obtains the bill of materials of all vehicles from the material system;

[0119] Step 704: receiving a feature subset of matching feature items sent by the feature maintenance system, and displaying the feature subset;

[0120] Step 706: receiving the inspection result input by the user, where the inspection result is obtained after the user performs assembly inspection based on the displayed sub-feature set matching feature items.

[0121] The specific implementation of this embodiment is similar to the above Figure 1 The embodiments shown are similar and will not be described again here.

[0122] In this embodiment, the terminal sends an assembly inspection instruction to the feature configuration system, and the assembly inspection instruction includes a vehicle identification, so that the MES can obtain the vehicle's bill of materials from the material system based on the vehicle identification, match the bill of materials with the feature set of all pre-stored component feature items, determine the matching feature items that match the bill of materials, and determine the feature subset that matches the bill of materials from the feature set of each matching feature item, so that the matching feature items corresponding to each vehicle and the feature subset of the matching feature items can be obtained, and the feature subset of the matching feature items is sent to the terminal so that the terminal can display the feature subset, and then receive the inspection results obtained by the user after performing an assembly inspection on the matching feature items based on the displayed feature subset, thereby realizing assembly inspection of the matching feature items of each vehicle. The present application predefines component feature items, and then obtains the bill of materials of all vehicles from the material system, and then extracts features from the bill of materials of all vehicles to construct a feature set of each component feature item. In this way, the feature sets of the component feature items that need to be checked are sorted, and then the feature subsets of matching feature items are obtained from the feature sets of all component feature items, and assembly inspection is performed on the matching feature items of the vehicle. Compared with directly assembling the vehicle based on the bill of materials, this avoids the situation where the inspection content is too much and messy, and improves the inspection efficiency. At the same time, manual configuration inspection is based on the feature subset sorted for the matching feature items, rather than directly assembling the vehicle based on the bill of materials, which reduces the probability of error.

[0123] In one of the embodiments, displaying the feature subset includes: determining a target component feature item from matching feature items based on a preset inspection order of the component feature items; and displaying the feature subset of the target component feature item.

[0124] The inspection order of component feature items can be preset in the terminal, or the inspection order of component feature items can be preset in the MES, and then the MES sends the inspection order of component feature items to the terminal;

[0125] Based on the inspection order, the target component feature items that need to be inspected are determined from the matching feature items, and after the feature subset of the target component feature items is displayed, the receiving user performs an assembly inspection of the matching feature items based on the feature subset, and can choose any of the three options: wrong installation, missing installation, and confirmed correct; if the actual vehicle information is consistent with the PAD display information, the personnel selects confirmed correct and proceeds to the next configuration feature inspection; if the actual vehicle information is inconsistent with the PAD display information, the personnel selects wrong installation or missing installation.

[0126] The terminal receives an instruction to check the next configuration feature. The instruction for the next configuration feature may be automatically generated after the personnel selects and confirms that the information on the actual vehicle is consistent with the information displayed on the PAD. After receiving the instruction, the terminal re-executes the inspection sequence based on the preset component feature items, determines the target component feature items from the matching feature items, displays the feature subset of the target component feature items, and receives the inspection result input by the user for the target component feature items, until all matching feature items are checked.

[0127] In one of the embodiments, displaying the feature subset of the target component feature item includes: acquiring predefined partial features and feature values ​​of the partial features from the feature subset of the target component feature item, and displaying the partial features and the corresponding feature values.

[0128] For example, if the feature subset of the target component feature item includes feature number, feature description, feature quantity, feature location, part number of the associated part, work center, etc., then only the feature number, feature description, feature quantity, feature location and the corresponding value can be displayed.

[0129] In one of the embodiments, the present application can also implement MES defect entry, specifically including:

[0130] For the component feature items, after the operator confirms that the component is mis-installed or missing and submits it through PAD, the MES defect entry module will automatically select the severity level of the problem and the responsible party, and push it to the person in charge of each responsible factory department to notify the corresponding person in charge for confirmation, so as to achieve rapid response and three current analysis. In addition, the MES system will automatically write relevant information such as the problem vehicle, problem description, problem severity level, problem responsible party, problem quantity, problem entry time, problem entry station, and problem entry personnel.

[0131] 3. Algorithm

[0132] This application adopts a combination of MES and BOM systems to display the sub-feature sets and feature images of the feature items of each component of the vehicle on the PAD, so that users can confirm them one by one.

[0133] 4. Compatibility

[0134] The features maintained in the MES system cover a variety of vehicle models, and are configured and checked for each model’s interior, exterior, functions, vehicle labels, etc., with strong compatibility.

[0135] 5. Run the program.

[0136] See also Figure 8 The overall solution process of the inspection method of the component feature items of the vehicle of this application is as follows:

[0137] 1. PAD scans the vehicle VIN code: When the vehicle arrives at the configuration inspection station with the plate chain, the PAD operator scans the barcode on the left rear quarter window of the vehicle or on the vehicle process card to identify the vehicle identification of the corresponding vehicle;

[0138] 2. Display of vehicle configuration information: PAD sends the vehicle identification to the MES system. After the MES system obtains the bill of materials of the corresponding vehicle from the material system, it matches the bill of materials of the vehicle with the feature set of the component feature items maintained in the MES system, and obtains the sub-feature set of all matching feature items of the vehicle from the MES system. The PAD system will display the main configuration information of the vehicle, such as the interior, exterior, function, chassis, and regulatory labels, such as material, color, size, function, etc.

[0139] 3. Comparison of vehicle configuration features: The operator compares the features of the vehicle's component features and feature images based on the PAD display content to confirm whether the physical object is consistent with the feature image and the text description of the displayed features. Figure 2 In the PAD interface, the feature picture is displayed, the feature number is xxx, and the feature name is vehicle emission control information label.

[0140] 4. Personnel confirmation: The PAD operator selects any of the three options: wrong installation, missing installation, and confirmed (ok) according to the PAD prompt; if the actual vehicle is consistent with the PAD information, the operator selects confirmed and proceeds to the next configuration feature check; if the actual vehicle is inconsistent with the PAD information, the operator selects wrong installation or missing installation.

[0141] 5. Submit: After all configuration feature information of the vehicle has been confirmed, the PAD operator clicks Submit; if there are wrong installation or missing options in all configuration checks, the system will automatically synchronize the information to the MES system, enter the problem, and notify the personnel in each department for confirmation.

[0142] Then wait for the next car and repeat the process for the next car.

[0143] 6. Technical indicators and requirements

[0144] Configuration features are 100% placed in the PAD configuration inspection system according to pictures and text descriptions.
