[0002] This section is intended to provide a background or context to the embodiments of the invention that are recited in the claims. No statement herein is admitted to be prior art by virtue of its inclusion in this section.

[0003] BIM (Building Information Management) components are the basic building blocks of BIM models and can represent building partitions, structural columns, point loads, beams, beam pads, steel bars, etc. They all have certain geometric information such as shape and size. In addition, they also have attribute information such as material, concrete strength and name. When the BIM model is established, all BIM components should be classified and coded so that relevant information can be quickly and accurately found in the subsequent process, such as engineering fraud and procurement. However, due to the complexity and large size of the steel plant, the number of BIM model components is huge. In addition, the requirements of project management are different and the implementation standards are different. At present, BIM model review can only be carried out manually, including the inspection and correction of component coding. As a result, the accuracy of BIM model review is difficult to guarantee and the review efficiency is low, which has seriously affected the comprehensive utilization of BIM engineering data. In the existing technology, although there are some automatic review methods for BIM models, such as converting BIM model database files into standard database files for compliance review, or automatically reviewing BIM models based on standard knowledge graph meta-structures, most methods are only applicable to the construction industry and are not convenient for expansion into other fields.

Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0024] The applicant found that due to the complexity and large size of the steel plant, the huge number of BIM model components, and the different project management requirements and the different implementation standards, the BIM model review can only be carried out manually, such as the inspection and correction of component coding. As a result, the accuracy of the BIM model review is difficult to guarantee, and the review efficiency is low, which has seriously affected the comprehensive utilization of BIM engineering data. In the prior art, although there are some automatic BIM model review methods, such as converting the BIM model database file into a standard database file for compliance review, or automatically reviewing the BIM model based on the standard knowledge graph meta-structure, most methods are only applicable in the construction industry, and are not convenient for expansion to other fields. They are not flexible enough and have poor adaptability. To this end, the applicant proposed a BIM model review method.

[0025] It should be noted that the acquisition, storage, use, and processing of data in the technical solution of this application comply with the relevant provisions of national laws and regulations.

[0026] Figure 1 Schematic diagram of a BIM model review method according to an embodiment of the present invention, which includes:

[0027] Step 101: Obtain the codes and multiple attribute information of all components in the BIM model. The component codes are generated according to digital coding rules when the BIM model is established. The digital coding rules are constructed in a tree structure. The tree structure includes multiple nodes and node description information. The nodes include a root node, child nodes, and leaf nodes. The key of each node includes an identifier of the node. The values ​​of the root node and child nodes include identifiers of the nodes at the next level. The value of the leaf node is empty.

[0028] Step 102: According to the coding of each component, obtain the node description information corresponding to each component from the digital coding rules;

[0029] Step 103: sequentially compare the node description information corresponding to each component with multiple attribute information of the same component, and output a matching degree for each component; the matching degree is used to indicate the degree of matching between the multiple attribute information of the component and the node description information corresponding to the component;

[0030] Step 104: Output the review result of each component of the BIM model based on the matching degree of each component.

[0031] from Figure 1As can be seen from the shown process, in the embodiment of the present invention, the coding and multiple attribute information of all components in the BIM model are obtained, and the node description information corresponding to each component is obtained from the pre-established digital coding rules; the node description information corresponding to each component is compared with the multiple attribute information of the same component in turn, and the matching degree of each component is output, and then the review result of each component of the BIM model is output. This method has no requirements for the application scenario and has good scalability, which expands the adaptability of BIM model review. At the same time, due to the digital coding rules, each node stores the node identifier in the form of a key-value pair, and the nodes are connected through the identifier. The data model is simple and can cope with complex data scenarios, thereby improving the accuracy and efficiency of BIM model review.

[0032] The BIM model review method in an embodiment of the present invention is explained in detail below.

[0033] During specific implementation, you can first review the working environment, the completeness of the BIM model files, and the digital coding rules that the BIM model coding relies on.

[0034] After receiving the BIM model file, all components in the BIM model are scanned, including but not limited to point elements, line elements, volume elements, surface elements, and unit elements. If a component is a unit element, the other elements (point elements, line elements, etc.) contained in the unit element are no longer scanned. The coding and attribute information of all components in the BIM model are obtained and stored in the form of a dictionary.

[0035] Among them, the coding of the component is generated according to the digital coding rules when the BIM model is established. The digital coding rules are constructed in a tree structure. The tree structure includes multiple nodes and node description information. The nodes include root nodes, child nodes, and leaf nodes. The root node is the node at the top of the tree structure. The child node is a node other than the root node and is connected to other nodes below it. The leaf node is the node at the end of the tree structure. No other nodes are connected below the leaf node. The key of each node in the tree structure includes the identifier of the node. The value of the root node and the child node includes the identifier of the node at the next level. The value of the leaf node is empty. In the embodiment of the present invention, each node of the digital coding rule stores the node identifier in the form of a key-value pair. The nodes are connected through the identifier. The data model is simple and can cope with complex data scenarios. The generated coding information has a high accuracy rate, thereby improving the efficiency of BIM model review.

[0036] Afterwards, according to the coding of each component, the node description information corresponding to each component is obtained from the digital coding rules.

[0037] Figure 2 This is a specific embodiment of the BIM model review method in the embodiment of the present invention, as shown in FIG. Figure 2As shown, according to the coding of each component, the node description information corresponding to each component is obtained from the digital coding rules, which may include:

[0038] Step 201: According to the code of each component, obtain the identifier of the node corresponding to the code of each component from the digital coding rule;

[0039] Step 202: Obtain node description information corresponding to each component according to the identifier of the node corresponding to the code of each component.

[0040] During implementation, the coding of components can use logical characters and digital identifiers, or a combination of random characters and numbers. The coding of components can correspond to the identifiers of nodes in the digital coding rules. According to the coding of components, all nodes in the digital coding rules are traversed to find the identifiers of the nodes corresponding to the coding of each component, thereby obtaining the corresponding node description information.

[0041] Afterwards, the node description information corresponding to each component is compared with multiple attribute information of the same component in turn, and the matching degree of each component is output; the matching degree is used to indicate the degree of matching between the multiple attribute information of the component and the node description information corresponding to the component.

[0042] During implementation, the component's attribute information is compared with the corresponding node description information to calculate the degree of match. For example, natural language processing can be used to split the attribute information into multiple words. These words are then compared with the node description information to calculate the degree of overlap. A threshold is set and the degree of match is determined based on the overlap and a preset threshold.

[0043] In order to improve the accuracy and efficiency of BIM model review, Figure 3 This is a specific embodiment of the BIM model review method in the embodiment of the present invention, as shown in FIG. Figure 3 As shown, the node description information corresponding to each component is compared with multiple attribute information of the same component in turn, and the matching degree of each component is output, which may include:

[0044] Step 301: For each component: compare the node description information corresponding to the component with each attribute information of the component, and output the matching degree between each attribute information of the component and the node description information corresponding to the component;

[0045] Step 302: Using an artificial intelligence algorithm, assign a weight to the matching degree between each attribute information of a component and the node description information corresponding to the component;

[0046] Step 303: Calculate and output the matching degree of each component based on the matching degree between each attribute information of the component and the node description information corresponding to the component, and the weight.

[0047] During implementation, component attribute information generally includes geometric attributes and non-geometric attributes, such as length, width, height, concrete grade, manufacturer, lifespan, price, etc. When calculating the matching degree, natural language processing is used to calculate the matching degree between each component attribute information and the corresponding node description information. Finally, the matching degree of each component can be calculated according to the following formula:

[0048]

[0049] Where S is the matching degree of the component, n is the number of component attribute information, r is the matching degree between the current component attribute information and the corresponding node description information of the component, which can take a value from 0 to 1, and t is the matching weight between the current component attribute information and the corresponding node description information of the component.

[0050] To further improve the accuracy of BIM model review, in one embodiment, an artificial intelligence algorithm is used to assign a weight to the degree of matching between each attribute information of a component and the node description information corresponding to the component, which may include:

[0051] Obtain the attribute information of all components in multiple historical BIM models and the weight of each attribute information of the components;

[0052] Establish training and test sets based on the attribute information of all components in multiple historical BIM models and the weight of each attribute information of the components;

[0053] Establishing a first machine learning model, training the first machine learning model using a training set, and testing the first machine learning model using a test set to obtain an attribute weight distribution model;

[0054] Input each attribute information of the component into the attribute weight distribution model, and output each attribute weight of the component;

[0055] The weight of each attribute of the component is used as the weight of the matching degree between each attribute information of the component and the node description information corresponding to the component.

[0056] Using artificial intelligence algorithms to assign weights is more objective and accurate than manually assigning weights.

[0057] Finally, in step 104, the review result of each component of the BIM model is output based on the matching degree of each component.

[0058] During implementation, the review results can be presented in the form of reports. These reports can include reports on qualified components, unqualified components, and BIM model components without attribute information. Items in the unqualified component report are displayed in different colors depending on the degree of matching. When the matching degree is greater than 90%, the item is blue; when the matching degree is less than 90% but greater than 75%, the item is yellow; and for other matching degrees, the item is red.

[0059] The review results can also be displayed in the form of visual views, including but not limited to pie charts, column charts, bar charts, and line charts. Similarly, in the visual view, different colors represent different matching degrees.

[0060] In one embodiment, the review result of each component is displayed in conjunction with the BIM model, and the linked display includes highlighting the review result of the component on the corresponding component in the BIM model.

[0061] During implementation, all report items support linkage with the BIM model. By clicking a report item, the BIM component can be linked, and the display operation and property viewing of the BIM component can be realized, including but not limited to highlighting and independent display of the BIM component (hiding all other elements). This makes it easier for users to view and improves the user experience.

[0062] In addition, all audit reports support output in other formats, including but not limited to Excel file format, XML format, Json format, etc.

[0063] The review results can also be output in the form of a review report, which can include the BIM model overview, a review list of qualified BIM components, a review list of unqualified BIM components, and a review list of BIM components without project attributes. The BIM model overview includes a component coding accuracy analysis and visual analysis charts. The accuracy analysis includes, but is not limited to, a component coding accuracy table and the distribution of matching degrees among unqualified components. The review lists of qualified and unqualified BIM components include, but are not limited to, component IDs, name identifiers, codes, attribute information, matching degrees, etc. The review report supports output in common document formats, including but not limited to Word and WPS formats.

[0064] In summary, the embodiments of the present invention provide a BIM model review method, which solves the problem of difficulty in reviewing component coding of BIM models, significantly improves the accuracy and efficiency of BIM model review, and expands the adaptability of BIM model review.

[0065] The present invention also provides a BIM model review device, as described in the following embodiments.
