[0020] like Figure 1 FIG. 1 is a flow chart of a preferred embodiment of a method for generating a bill of materials for steel structures according to the present invention. The order of the steps in the flow chart may be changed and some steps may be omitted according to different requirements.

[0027] The network where the computer device is located includes but is not limited to the Internet, wide area network, metropolitan area network, local area network, virtual private network (VPN), etc.

[0028] S10, extracting steel structure engineering files based on a designated building information modeling platform, and parsing the steel structure engineering files to obtain component attribute data and component assembly relationships of each steel structure component in the steel structure engineering files.

[0029] In this embodiment, the designated building information modeling platform may be a BIM platform (Building Information Modeling Platform). The designated building information modeling platform is a software system or online service platform based on BIM technology that integrates various building information and functions to provide support for the full life cycle management of construction projects.

[0030] In this embodiment, steel structure engineering documents refer to various types of documents and materials generated and used during the entire life cycle of a steel structure engineering project, from planning, design, construction to completion acceptance, operation and maintenance, etc., which are of great significance to the smooth progress of the project, quality assurance, and post-maintenance.

[0031] For example: the steel structure engineering documents may include, but are not limited to, preliminary documents such as project approval documents, construction land documents, survey and design documents (including geological survey reports, design drawings, design change documents, etc.), construction management documents (including construction organization design, construction log), engineering quality documents (including raw material quality certification documents, welding process assessment reports, weld flaw detection reports, high-strength bolt connection friction surface anti-slip coefficient test reports, component production inspection records, hidden engineering acceptance records), construction safety documents (including safety management plans, safety inspection records) and other construction process documents, as well as completion acceptance documents (including completion acceptance reports, engineering quality acceptance records, as-built drawings), operation and maintenance documents (including instruction manuals, maintenance plans, repair records), etc.

[0032] In this embodiment, extracting steel structure engineering files based on a designated building information model platform includes: Establishing communication with the steel structure component database via the API (Application Programming Interface) of the designated building information model platform; The steel structure engineering file is extracted from the steel structure component database.

[0033] The steel structure component database is used to centrally store and manage steel structure related component information.

[0034] In the above embodiment, by specifying the API interface of the building information model platform to communicate with the component database of the steel structure project, it can assist in achieving efficient, accurate and automatic generation of BOM (Bill of Materials), which is applicable to various steel structure engineering projects.

[0035] In this embodiment, the component attribute data of each steel structure component may include, but is not limited to, one or a combination of the following information: the component's global ID, quantity, cross-section, material, length, weight, and remarks.

[0036] In this embodiment, the component assembly relationship refers to the connection mode and subordinate relationship between the components.

[0037] S11, generate the number of each steel structure component according to the configuration rules.

[0038] In this embodiment, the step of generating a number for each steel structure component according to the configuration rule includes: Check whether each steel structure component has been numbered; For each steel structure component that has a number, determine the existing number of each steel structure component as the number of each steel structure component; or For each unnumbered steel structure component, determine the type of each steel structure component; generate a number header for each steel structure component according to the type of each steel structure component; configure a self-incrementing ID for each steel structure component according to the numbering sequence of each steel structure component; combine the number header of each steel structure component and the corresponding self-incrementing ID to obtain the number of each steel structure component.

[0039] The type of each steel structure component may include, but is not limited to, steel beams, steel columns, connecting plates, etc.

[0040] For example, for each unnumbered steel structural component, first count all component types (such as beams, columns, and connecting plates) and assign each type an auto-incrementing ID. The auto-incrementing ID is a consecutive positive integer starting at 1 and automatically incremented by 1 after each assignment. Furthermore, each steel structural component can be numbered by appending the first letter of the type name to the auto-incrementing ID. For example, a beam could be numbered "B-1." If a component already has an assigned number, the original number is used.

[0041] S12, establishing a mapping relationship between the serial number of each steel structure component and the corresponding component attribute data.

[0042] In this embodiment, after establishing the mapping relationship between the serial number of each steel structure component and the corresponding component attribute data, the method further includes: The number of each steel structure component is determined as a key, and the corresponding component attribute data is determined as a value to construct a key-value pair; The key-value pairs are stored in memory based on a memory cache mechanism.

[0043] Through the memory caching mechanism, component information can be quickly accessed, repeated database queries can be avoided, and data retrieval efficiency can be significantly improved.

[0044] S13, constructing a BOM tree according to the component assembly relationship and the number of each steel structure component.

[0045] In this embodiment, constructing a BOM tree according to the component assembly relationship and the number of each steel structure component includes: Initialize the project virtual root node as the top node; According to the component assembly relationship, the BOM tree is obtained by sequentially extending downward from the top node as a starting point to connect the numbers of each steel structure component; In the BOM tree, the number of each steel structure component is determined as each tree node, and the tree nodes are connected as directed edges between the tree nodes according to the component assembly relationship between the steel structure components.

[0046] Specifically, a virtual root node for the project can be generated by default as the top-level node of the BOM tree, connecting all first-level component nodes. Furthermore, the assembly relationships between components are determined, and directed edges connect parent nodes and child nodes, forming a tree structure with component numbers as nodes (i.e., components as tree nodes) and assembly relationships as edges, which serves as the BOM tree.

[0047] By constructing a BOM tree, the parent-child relationship between components can be displayed more clearly in a hierarchical manner.

[0048] S14 , in response to the steel structure material list generation instruction, parsing the steel structure material list generation instruction to obtain a traversal range.

[0049] In this embodiment, the steel structure material list generation instruction can be automatically triggered when a relevant operation on a designated user interaction interface is detected.

[0050] In this embodiment, the traversal range obtained by parsing the steel structure material list generation instruction includes: Parsing the steel structure material list to obtain user operations; Determine the three-dimensional coordinate range of the frame selection according to the user operation; The traversal range is determined according to the three-dimensional coordinate range.

[0051] Through the above embodiments, the traversal range can be automatically determined, redundant information can be eliminated, and the traversal efficiency can be improved.

[0052] S15, screening the BOM tree according to the traversal range to obtain a target component number.

[0053] In this embodiment, the target part number can be filtered out from the BOM tree according to the three-dimensional coordinate range defined by the traversal range.

[0054] S16: Acquire component attribute data corresponding to each target component number as target attribute data according to the mapping relationship.

[0055] In this embodiment, each target component number can be used to perform a matching query in the mapping relationship, thereby obtaining component attribute data corresponding to each target component number as the target attribute data.

[0056] S17, using a depth-first search algorithm to traverse the target component numbers in sequence, and processing the target attribute data based on a recursive transfer mechanism during the traversal process to obtain multiple BOM rows.

[0057] In this embodiment, the depth-first search algorithm is used to sequentially traverse the target component numbers, and the target attribute data is processed based on a recursive transfer mechanism during the traversal process to obtain multiple BOM lines including: Configure the initial state of the tree node corresponding to each target zero component number to the first state; Traverse the tree nodes corresponding to each target component number in order from smallest to largest depth; During the traversal process, for a current tree node traversed, the state of the current tree node is configured as the second state, the accumulated material item attribute values ​​up to the current tree node are calculated according to the recursive transfer mechanism, and the current BOM line is generated according to the material item attribute values; When it is detected that the states of all tree nodes are the second state, the traversal is stopped and the generated multiple BOM rows are obtained.

[0058] For example, the initial access state of the filtered zero-component nodes is configured as False, that is, the first state, and the tree nodes are sorted in order of depth from small to large. The specific traversal method is as follows: ① Update the access status of the currently traversed tree node to True, which is the second state; ② Recursively traverse all child nodes of the current tree node, and in the traversal process, calculate the weight, area and other calculated attributes of the component (i.e., the attribute value of the material item) through recursive transfer, and generate the corresponding BOM row set based on the number and attribute data; ③ Determine the access status of the tree nodes corresponding to all zero-components. If all are True, then all zero-component nodes have been visited. If there is False, then the first node with a False access status is configured as the current node. ④ Repeat steps ①-③ until all tree nodes have been visited, that is, the visit status of all nodes is True.

[0059] S18, integrating the multiple BOM rows to obtain a steel structure material list.

[0060] This embodiment has the advantages of high degree of automation, fast data processing efficiency and accurate BOM generation, which can significantly improve the efficiency of generating bills of materials in steel structure projects. It is suitable for various steel structure engineering projects and has broad application prospects and practical value.

[0061] It can be seen from the above technical solutions that the present invention can generate the number of each steel structure component according to the configuration rules, and construct a BOM tree according to the component assembly relationship and the number of each steel structure component to provide a traversal basis; parse the steel structure material list generation instruction to automatically obtain the traversal range, filter the BOM tree according to the traversal range to obtain the target component number, realize the preliminary screening of the components, remove redundant information, and thus improve the traversal efficiency; adopt a depth-first search algorithm to traverse the target component number in sequence, and process the target attribute data based on the recursive transfer mechanism during the traversal process to obtain multiple BOM rows, integrate multiple BOM rows to obtain a steel structure material list, and thus combine the depth-first search algorithm and the recursive transfer mechanism to automatically, comprehensively, accurately and quickly generate a steel structure material list.
