[0011] Among them, the types of initial attribute data corresponding to the first component include: component type, component material, and component size information. The component type defines the type of component, such as beams, columns, slabs, walls, piers, abutments, ditches, etc., to clarify its functions and application scenarios. The component material is the material used for the component, such as reinforced concrete, steel, wood, etc., and includes its strength grade and physical properties. The component size information is used to specify the geometric dimensions of the component, including length, width, height, thickness, etc. Furthermore, the types of the initial attribute data also include: cost information and construction process information; the cost information is to provide the unit price and total cost estimate of the component, covering material costs, processing costs, transportation costs, etc.; the construction process information details the manufacturing, installation and acceptance process of the component, including the required tools, equipment and construction conditions.

[0012] In one embodiment of the present invention, different first engineering data dictionaries have different technical fields; In another embodiment of the present invention, different first engineering data dictionaries correspond to different preset domain files, which include national and industry-related standards and normative documents.

[0013] Specifically, the first component ID is the unique identifier of the first component; and the naming of the first component adopts a standardized format, such as camel case or underscore, to avoid ambiguity. In addition, the units corresponding to the first component are unified to the International System of Units (SI), such as meter (m) for length and Newton (N) for force, to avoid conversion errors. For the specification parameters of materials and components, reference should be made to standard libraries, such as the national building standard library or industry specifications, to ensure the accuracy of parameter selection.

[0014] Furthermore, the First Engineering Data Dictionary supports version updates to enable effective updates and maintenance at different stages of the BIM model, ensuring the timeliness and accuracy of the data.

[0015] S200, obtaining a plurality of second engineering data dictionaries, each of which includes a plurality of second component attribute mapping data, wherein the second component attribute mapping data includes a second component ID, second description information of the second component ID, and initial attribute data corresponding to the second component; wherein the source of the first component attribute mapping data is different from the source of the second component attribute mapping data, and the second description information includes at least the field information corresponding to the second component.

[0016] Specifically, the type of the initial attribute data corresponding to the second component is the same as the type of the initial attribute data corresponding to the first component.

[0017] Specifically, the sources of the first component attribute mapping data and the second component attribute mapping data are different. It can be understood that the source of the second component attribute mapping data is other sources that are not obtained based on preset domain files. In one embodiment of the present invention, the source of the second component attribute mapping data is obtained based on historical component attribute information to avoid the problem of lack of domain normative documents or fewer domain normative documents in individual small fields.

[0018] S300, analyzing the acquired user request to acquire target component information, wherein the target component information at least includes a target component ID and target domain information corresponding to the target component.

[0019] Specifically, those skilled in the art know that any method of analyzing user requests to obtain target component information in the prior art falls within the protection scope of the present invention, such as using a large language model to analyze the obtained user requests to obtain target component information.

[0020] S400, use the target component information and the first component attribute mapping data to perform matching to obtain a first matching result, wherein the first matching result is a weighted sum of the first component matching degree value and the first description matching degree value, wherein the first component matching degree value is a matching degree value between the target component ID and the first component ID, and the first description matching degree value is a matching degree value between the target domain information and the first description information.

[0021] Optionally, the weight of the first component matching degree value is not greater than the weight of the first description matching degree value; preferably, the weight of the first component matching degree value is equal to the weight of the first description matching degree value.

[0022] S500: If the first matching result meets the preset matching requirement, the first component attribute mapping data corresponding to the first matching result is used as the target component attribute mapping data, and a target component corresponding to the user request is generated based on the target component attribute mapping data.

[0023] Specifically, if the first matching result meets the preset matching requirement, that is, if the first matching result is greater than the preset matching threshold.

[0024] S600, if the first matching result does not meet the preset matching requirement, use the target component information and the second component attribute mapping data for matching to obtain a second matching result, wherein the second matching result is a weighted sum of the second component matching degree value and the second description matching degree value, wherein the second component matching degree value is a value of the matching degree of the target component ID and the second component ID, and the second description matching degree value is a value of the matching degree of the target domain information and the second description information; Optionally, the weight of the second component matching degree value is not greater than the weight of the second description matching degree value; preferably, the weight of the second component matching degree value is equal to the weight of the second description matching degree value.

[0025] S700: If the second matching result meets the preset matching requirement, the second component attribute data corresponding to the second matching result is used as the target component attribute mapping data, and a target component corresponding to the user request is generated based on the target component attribute mapping data.

[0026] Specifically, if the second matching result meets the preset matching requirement, that is, if the second matching result is greater than the preset matching threshold.

[0027] Further, if none of the second matching results meets the preset matching requirement, a request is sent to the user to obtain the target component attribute mapping data provided by the user.

[0028] In summary, several first engineering data dictionaries are obtained, several second engineering data dictionaries are obtained, user requests are obtained, and the user requests are analyzed to obtain target component information, and the target component information and the first component attribute mapping data are used for matching to obtain a first matching result. If the first matching result meets the preset matching requirements, the first component attribute mapping data corresponding to the first matching result is used as the target component attribute mapping data. If the first matching result does not meet the preset matching requirements, the target component information and the second component attribute mapping data are used for matching to obtain a second matching result. Based on the target component information and the target component attribute mapping data, the target component corresponding to the user request is generated. The present invention provides basic attribute data for parametric components on the basis of engineering data dictionaries, realizes unified management and efficient use of data, and improves the overall efficiency of BIM data management. In addition, the present invention combines the standardized management of data dictionaries with the flexible design of parametric components to improve the adaptability and application effect of components.

[0029] Specifically, in S700, if the second matching result meets the preset matching requirement, the second component attribute data corresponding to the second matching result is used as the target component attribute mapping data, and a target component corresponding to the user request is generated based on the target component attribute mapping data, further comprising: Acquire other attribute data input by the user. Specifically, the types of the other attribute data include date, string, double-precision floating point number, integer int, etc.

[0030] Further, if the second matching result meets the preset matching requirement, the second component attribute data corresponding to the second matching result is used as the target component attribute mapping data, and a target component corresponding to the user request is generated based on the target component attribute mapping data, further comprising: The parameter value input by the user is obtained, wherein the parameter value corresponds to the intermediate attribute data, and the intermediate attribute data includes other attribute data and initial attribute data in the target component attribute mapping data.

[0031] Specifically, in one embodiment of the present invention, the user directly inputs a fixed parameter value through a simple input box or a drop-down menu; in another embodiment of the present invention, the user inserts a preset formula through a formula editor, and automatically generates a new parameter value based on the existing parameter value and the preset formula. For example, when the user inserts the preset formula "total weight = material density * volume", when there are parameter values ​​corresponding to the existing material density and volume, the parameter value corresponding to the total weight will be automatically calculated and generated.

[0032] Construct the initial geometry.

[0033] Specifically, rough geometric bodies are manually created in the BIM platform, such as conventional cubes, rectangular blocks, cylinders, spheres, and stretching, sweeping, rotation, Boolean intersection and difference, etc. provided by the geometric modeling engine are used to obtain relatively rough geometric bodies to achieve dynamic adjustment of the geometric model.

[0034] The parameter values, initial attribute data in the target component attribute mapping data and other attribute data are injected into the initial geometry to generate the target component.

[0035] In summary, the parameter values ​​input by the user are obtained, the initial geometry is constructed, the parameter values, the initial attribute data in the target component attribute mapping data and other attribute data are poured into the initial geometry, and the target component is obtained. The present invention supports the user to input fixed values, and also supports the user to generate calculation expressions according to the existing attribute data through the formula editor, and automatically calculate and generate new attribute data to ensure the data diversity of the target component.

[0036] Furthermore, after obtaining the target component, it also includes: The target component and its related parameters are stored in the corresponding component library, where different types of target components correspond to different component libraries. Specifically, the target component and its related parameters are stored in the corresponding component library for use and call in subsequent projects. When a user creates or modifies a parametric component in the BIM software, the system will automatically store the geometric model of the component and related attribute data in the component library. This includes the basic attributes of the component (such as material, size, cost, etc.), as well as user-defined extended attributes and formula calculation results. When the same or similar component is used later, the component can be directly called for use.

[0037] An embodiment of the present invention also provides a non-transitory computer-readable storage medium, which can be set in an electronic device to store at least one instruction or at least one program related to implementing a method in a method embodiment.
