Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of data processing, and in particular to a BOM generation method and device based on 3D modeling, equipment and medium. BACKGROUND

[0002] With the development of industrial software and CAD (Computer Aided Design) modeling, in the manufacturing industry, engineering construction field, aerospace and other fields, BOM (Billof Material) as the core data, is the key information carrier of product design, production, procurement, inventory management and other links, throughout the product life cycle, and provides accurate material list and structure information for each link. The steel structure BOM contains component code, part code, part specification, quantity, process note and other contents.

[0003] At present, the production of BOM mainly includes manual and simple BOM automatic generation scheme.

[0004] In the manual scheme, the design department uses design software to draw component drawings, and the drawings have a material specification table. The list department needs to manually transcribe the content of the specification table from the drawing to EXCEL. For example: for welded profiles, it needs to be manually disassembled into plate parts; for parts, it needs to manually obtain processing information such as corner cutting, hole punching, blanking, geometric shape from the drawing and input into the BOM, and at the same time, the parts that need to be punched and punched are integrated into a small plate drawing. Finally, the bolts and straight hair parts are counted and summarized. In the simple automatic BOM generation scheme, the materials used are exported to EXCEL.

[0005] However, the manual operation mode is highly dependent on manual operation, and is full of repetitive labor, which makes it difficult to improve work efficiency. Moreover, the current work flow makes the design model and the BOM disconnected, and the enterprise therefore lacks an integrated and unified design data source, which to a large extent hinders the continuous advancement of the enterprise informatization process and breaks the relationship between the design model and the BOM. The simple BOM automatic generation scheme lacks some basic data processing functions of BOM information and methods for dealing with multi-level steel structures. SUMMARY

[0059] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be described in detail below in combination with the drawings and specific embodiments.

[0060] As shown in Figure 1 is a flow chart of a preferred embodiment of the BOM generation method based on 3D modeling of the present application. The order of steps in the flow chart can be changed according to different needs, and some steps can be omitted.

[0068] S10, in response to a steel structure BOM (Billof Material, bill of material) generation instruction based on the target 3D model, analyzing the steel structure BOM generation instruction to obtain at least one list type and a list storage location corresponding to each list type.

[0069] In this embodiment, the target 3D model can be a 3D model of a steel structure.

[0070] In this embodiment, the steel structure BOM generation instruction can be triggered through a user interaction interface. For example, when it is detected that a 3D model is uploaded on a specified user interaction interface and a specified button is clicked, it can be determined that the steel structure BOM generation instruction is received.

[0071] The user interaction interface can be an interaction interface of a BOM generation system. Before generating a BOM by using the system, three main steps of registering a command, configuring an interface and implementing a command are sequentially executed to realize configuration of a system environment. Specifically, first, the system is registered by using an APP module through a registration command and a business program. Then, the interface is configured to allow a user to visually design through a command bar and a command configuration workbench. Finally, the implementation command stage involves UI (User Interface) registration, entry registration and execution of a core program. The BOM file generation part includes software environment adaptation, data structure definition and output file operation. The software environment adaptation stage ensures compatibility with a dynamic link library, and a VS (Visual Studio) + QT + Cpp (C++) development environment is used. The data structure definition stage involves setting of zero construction Key and zero construction Value. The output file operation stage realizes reading and writing of a file through IOstream and Fstream, and finally realizes BOM output function through compiling a DLL and starting ZWBIM.

[0072] In the embodiment, the parsing the steel structure BOM generation instruction to obtain at least one list type and a list storage location corresponding to each list type includes:

[0073] Connecting to a user interaction interface triggering the steel structure BOM generation instruction;

[0074] Obtaining a pre-maintained behavior detection list; wherein the behavior detection list includes the user interaction interface, a user behavior record log and a user behavior response module;

[0075] Based on the user behavior record log and the user behavior response module in the detection list, analyzing user behaviors generated on the user interaction interface, and determining the at least one list type and the list storage location corresponding to each list type according to the user behaviors.

[0076] The list type can include, but is not limited to, a component part list, a selected component list, a part belonging list and a material list.

[0077] For example, when detecting that a user selects an operation behavior record of "material list" from a drop-down list, it can be determined that "material list" is selected as a list type.

[0078] S11, splitting the target 3D model to obtain target zero component entry information.

[0079] In the embodiment, the splitting the target 3D model to obtain target zero component entry information includes:

[0080] Obtaining a preset number of parent components in the target 3D model; wherein the parent component comprises a sub-component and a part;

[0081] Identifying a welding type component and a non-welding type component in the parent component;

[0082] For the H-shaped component in the welding type component, the H-shaped component is split into one web plate and two flange plates;

[0083] For the plate type component in the welding type component, the plate type component is split into a plurality of small plates;

[0084] For the T-shaped component in the welding type component, the T-shaped component is split into one web plate and one flange plate;

[0085] For the arc-shaped beam in the welding type component, the arc-shaped beam is split into a main beam and a vice beam body, and is separated from the support;

[0086] For the pipeline in the welding type component, the pipeline is split into a main pipe and a branch pipe;

[0087] Integrating all the split zero components to generate the target zero component item information.

[0088] The preset number can be configured according to actual BOM generation requirements. For example, the preset number can also be obtained by analyzing the steel structure BOM generation instruction.

[0089] In the above embodiment, the 3D model can be split according to different zero component types.

[0090] S12, obtaining the pre-stored reference zero component information, and one-to-one mapping the target zero component item information with the reference zero component information to obtain a mapping table.

[0091] For example, each zero component item in the target zero component item information can be one-to-one corresponding to the view name, view origin, specification, material, weight, etc. in the reference zero component information, so that the corresponding storage of the zero component information can be realized after the 3D modeling is completed.

[0092] S13, according to each list type, using breadth-first algorithm and depth-first algorithm to traverse the target zero component item information, and processing the traversed zero component item according to the hash table algorithm and the mapping table in the traversal process, to obtain an initial BOM corresponding to each list type.

[0093] In this embodiment, the traversal of the target zero component item information according to each list type using breadth-first algorithm and depth-first algorithm comprises:

[0094] When the list type is a parts list for a component, the depth-first algorithm is used to randomly select an arbitrary component as a traversal starting point, and the direct subcomponents and / or subparts contained in the arbitrary component are recorded in a first list; for each subcomponent and / or subpart, the next-level subcomponents and / or subparts are selected one by one in a recursive manner and recorded in the first list, until all subcomponents and / or subparts are traversed, and the currently obtained first list is determined as the parts list for the component;

[0095] When the list type is a selected component list, a parts ownership list, or a material list, the breadth-first algorithm is used to create a queue including top-level components; in each round of traversal, any component is randomly taken out from the queue and it is checked whether the arbitrary component meets the configuration conditions; when the arbitrary component meets the configuration conditions, the arbitrary component is added to the second list, and the direct sub-components and / or sub-parts of the arbitrary component are added to the queue; until the queue is empty, the currently obtained second list is determined as the selected component list, the parts ownership list, or the material list.

[0096] For example, taking the parts list of a component as an example, the traversal process is as follows:

[0097] 1. Select a component as the starting point.

[0098] 2. Access the component and record its direct child parts in the list.

[0099] 3. For each subpart, if it also contains the next level of subparts, recursively traverse its depth and repeat steps 2 and 3 until all subparts are visited.

[0100] 4. After traversing a component and all its sub-parts, continue to process the next component until all components that need to be processed are traversed.

[0101] For another example: Taking the selected component list as an example, the traversal process is as follows:

[0102] 1. Create a queue and add the top-level component of the model to the queue.

[0103] 2. Take a component from the queue, check if it meets the conditions, and add it to the list if it does.

[0104] 3. Add all direct subcomponents of this component to the queue.

[0105] 4. Repeat steps 2 and 3 until the queue is empty, that is, all components have been checked.

[0106] Through the above embodiments, more suitable traversal methods can be selected according to different list types to perform traversal, which can improve traversal efficiency while ensuring accuracy.

[0107] In the embodiment, the processing of the traversed zero-component entries according to the hash table algorithm and the mapping table during the traversal process obtains an initial BOM corresponding to each list type, which includes:

[0108] For each zero-component traversed, the zero-component is matched in the mapping table to obtain feature information of the zero-component;

[0109] The feature information is calculated according to the hash table algorithm to obtain a calculation result;

[0110] The calculation result is sequentially added to a feature field corresponding to the zero-component in each list type to obtain an initial BOM corresponding to each list type.

[0111] For example, the initial BOM can include component number, part number, part specification, quantity, cross-sectional profile, material, length, weight, process note, and other feature information.

[0112] The embodiment classifies and integrates all zero-components belonging to the same parent component in a systematic manner, and organizes these zero-components under the same product node, ensuring the relevance and logic between parts, and facilitating efficient management and traceability in subsequent processing, assembly, and quality control processes.

[0113] The embodiment realizes a substantial reduction in labor demand by comprehensively traversing, analyzing, and accurately annotating components in the 3D model and automatically generating a BOM covering various entries, thereby greatly improving work efficiency. In addition, the embodiment successfully builds a bridge between the 3D model and the BOM, effectively promoting the enterprise informatization construction to a deeper level.

[0114] S14, obtaining configured additional entry attributes, and updating the initial BOM according to the additional entry attributes to obtain a target BOM.

[0115] In the embodiment, the updating of the initial BOM according to the additional entry attributes to obtain a target BOM includes:

[0116] Obtaining at least one feature information corresponding to the additional entry attributes;

[0117] Adding up the feature information of each zero-component belonging to the same zero-component type to obtain an accumulated value corresponding to each feature information;

[0118] Add the corresponding cumulative value to the initial BOM to obtain the target BOM.

[0119] For example, when the total weight or total area is required as an additional item attribute, the weight or area of each component belonging to the same component type can be added, and the calculated total weight or total area can be added to the initial BOM to obtain the target BOM.

[0120] Of course, other information such as generation time can also be added.

[0121] Through the above embodiment, information expansion can be performed on the basis of the reference BOM to meet the customization requirements.

[0122] S15, in response to a preview instruction of the target BOM, displaying a preview image of the target BOM on the configuration interface.

[0123] In this embodiment, the user can preview the generated BOM to determine whether the generated BOM meets the requirements, thereby further ensuring the accuracy of the generated BOM.

[0124] S16, in response to an export instruction of the target BOM, outputting and displaying the target BOM and storing the target BOM to a corresponding list storage location.

[0125] In this embodiment, when the user triggers the export instruction of the target BOM based on the preview effect, the BOM can be finally output.

[0126] In this embodiment, the output and display of the target BOM include:

[0127] Converting the target BOM into a table;

[0128] Converting the table into a visual table through visual programming software;

[0129] Displaying the visual table on a designated interface.

[0130] For example, the target BOM can be first converted into an Excel table, and then the Excel table can be converted into a visual table through visual programming software. The output file operation stage can realize file reading and writing through IOstream and Fstream, and finally realize BOM output through compiled DLL and started ZWBIM.

[0131] Through the above embodiment, the BOM can be converted into a more clear visual table, thereby improving the user experience.

[0132] The present embodiment can be applied to various engineering design and manufacturing scenarios.

[0133] From the above technical solutions can be seen, the application can split the target 3D model to obtain target component item information, and one-to-one map the target component item information with the reference component information to obtain a mapping table, so that the synchronization storage of component information can be realized when the 3D modeling is completed; according to each list type, the breadth-first algorithm and the depth-first algorithm are used to traverse the target component item information, and the component items traversed are processed according to the hash table algorithm and the mapping table in the traversal process, so that the initial BOM corresponding to each list type is obtained, the traversal mode can be selected according to different list types, so that the BOM can be generated more efficiently and accurately; the initial BOM is updated according to the additional item attribute to obtain the target BOM, further meeting the customized demand; the preview image of the target BOM is displayed on the configuration interface, and the target BOM is output and displayed after receiving the export instruction, so that the accuracy of the generated BOM is further ensured.
