The naming or numbering of the steps in this application does not mean that the steps in the method flow must be executed in the time / logical sequence indicated by the naming or numbering. The already named or numbered process steps can be changed in the execution order according to the technical objectives to be achieved, as long as the same or similar technical effects can be achieved.

[0051] An independently described module or sub-module may or may not be physically separated; it may be implemented in software or in hardware, and some of the modules or sub-modules may be implemented in software, with the processor invoking the software to implement the functions of these modules or sub-modules, and other parts of the modules or sub-modules being implemented in hardware, e.g., through a hardware circuit. In addition, some or all of the modules can be selected according to actual needs to achieve the purpose of the solution of the present application.

[0052] Please refer to Figure 1 - Figure 2 , the BIM-based road construction management method provided by the present invention includes: S101: Obtain all the basic data for building the BIM model, classify the basic data by type, obtain several groups of basic data of the same type, and perform a gradient division of the inclusion relationship for each group of basic parameters of the same type, obtaining first-level data, second-level data, and third-level data. The second-level data is within the type range of the first-level data, and the third-level data is within the type range of the corresponding second-level data;

[0053] Among them, the basic data for building the BIM model includes geometric parameters: defining the size and shape of the objects in the model to ensure an accurate three-dimensional representation. Material properties: recording the material type and its physical properties, such as strength and thermal conductivity. Structural parameters: including the cross-sectional dimensions and load-bearing capacity of beams and columns to ensure structural safety. MEP parameters: covering pipe diameters, wire specifications, etc. to ensure the effectiveness of the system. Cost estimation: including material and labor costs to assist in budget management. Safety parameters: including the location of fire-fighting equipment and safety exits to ensure the safety of personnel. Energy efficiency: such as insulation and daylighting parameters to improve the energy efficiency of the building, etc.

[0054] The data ranges included in the first-level data, second-level data, and third-level data decrease in sequence. For example, there are several basic data, which are respectively: the total length data of the current project road, the total length data of section I of the road, the total length data of section II of the road, and the current construction progress data of section I of the road.

[0055] Then, the total length data of the current project road can be classified as first-level data, the total length data of section I of the road and the total length data of section II of the road can be classified as second-level data, the current construction progress data of section I of the road is third-level data, and the current construction progress data of section I of the road corresponds to the third-level data of the total length data of section I of the road.

[0056] The first-level data, second-level data, and third-level data form an inclusion relationship, that is, the first-level data includes the second-level data, and the second-level data includes the third-level data. It can also be understood that the second-level data is more detailed or subordinate data of the first-level data, and the third-level data is more detailed or subordinate data of the second-level data.

[0057] It should be noted that all the relationships expressed in the above solutions are one-to-one correspondences. Not all secondary data are included in all primary data. Only when a secondary data has a corresponding relationship with a certain primary data, can a certain secondary data be included in a certain primary data. Similarly, there should also be a corresponding relationship between secondary data and tertiary data.

[0058] Regarding whether there is a corresponding relationship, it can be judged according to the relevant criteria for road construction, and the present invention will not elaborate further.

[0059] S102: Construct a number of structural tree models based on the number of groups of the divided basic parameters. The structural tree model includes a trunk, a first branch, and a second branch. Integrate the data of the primary data into the trunk, integrate the data of the secondary data into the first branch, and integrate the data of the tertiary data into the second branch;

[0060] The structural tree model is similar to a topological network structure. A corresponding pipe system is formed between each node and each node. This embodiment is only for demonstration, and the second branch is cited. Under the second branch, a third branch can also be formed, etc., and finally a topological network structure in which all basic data has a certain correlation is formed.

[0061] S103: The first branch is connected to the trunk, and the first branch and the trunk form a first connection node. The second branch is connected to the corresponding first branch, and the first branch and the second branch form a second connection node, and different symbols are used to mark the first connection node and the second connection node for subsequent retrieval;

[0062] Among them, each connection node can be associated with two basic data, so that the retrieval through the connection node can improve the retrieval efficiency to a certain extent.

[0063] S104: Combine all the structural tree models to form a database. When receiving a retrieval instruction for the basic data sent externally, retrieve the database to obtain the structural tree model where the basic data is located;

[0064] S105: According to the corresponding branch where the basic data is located, obtain the target basic data on the structure tree, and output the target basic data to the BIM model for model construction.

[0065] Specifically, create a basic coordinate system, set the coordinate origin, direction, and scale of the project. Ensure that all models and planes are carried out under a unified coordinate system.

[0066] Build 3D models and gradually create 3D models based on design drawings or architectural requirements. Including building structures (walls, beams, columns, floors, roofs), MEP systems (pipes, wires, equipment), landscapes and other parts. You can use parametric components and families to improve modeling efficiency.

[0067] Get relevant information from the basic data, add attributes and parameters, and add attributes and parameters to each object in the model (such as walls, doors, windows, etc.). Include information such as size, material, specification, cost, quantity, etc. Ensure the accuracy and completeness of the data in the model. Model partitioning and layering divide the model into different areas (such as building partitions, floor partitions). Perform layered management according to function or discipline (structure, architecture, MEP, landscape, etc.).

[0068] The above scheme provided by the invention mainly includes classifying the basic data into types, obtaining several groups of basic data of the same type, performing gradient division of the inclusion relationship on each group of basic parameters of the same type, and constructing a structure tree model based on the data divided by the gradient, and integrating the primary data, secondary data and tertiary data into the constructed structure tree model respectively. Through the above method, all basic data are uniformly associated, and when searching for basic data, all basic data associated with the basic data can be obtained according to the position of the structure tree model where the basic data is located, and according to the current modeling requirements, the required modeling basic data can be selected from all the associated numbers that have been obtained, so that the speed of modeling can be greatly improved, and the problem of opening irrelevant basic data and causing data redundancy can be avoided as much as possible.

[0069] In an exemplary embodiment of the present invention, obtaining target basic data on the structure tree according to the corresponding tree branch where the basic data is located includes:

[0070] Determine whether the current basic data is located in the trunk, the first branch or the second branch; if it is located in the trunk, obtain all the basic data of the structure tree where the current basic data is located as the target data for output; if it is located in the first branch, obtain all the basic data on the first branch where the current basic data is located on the structure tree as the target data for output; if it is located in the second branch, obtain all the basic data on the second branch where the current basic data is located on the structure tree as the target data for output.

[0071] Through the above method, when performing BIM modeling, there is a clear way to obtain the basic parameters of the road construction project, which can improve the efficiency of final model generation as much as possible and avoid using a large amount of useless data.

[0072] An exemplary embodiment of the present invention, the type division of the basic data includes:

[0073] Set the types of all basic data, and the types include image data, numerical data, and video data;

[0074] Identify the basic attributes of the basic data, and divide the basic data into types based on the basic attributes.

[0075] An exemplary embodiment of the present invention further includes:

[0076] Obtain the control instructions of the currently constructed BIM, and obtain the basic parameters of the target BIM model to be constructed currently through the control instructions;

[0077] Construct a basic parameter evaluation model, evaluate the basic parameters of the target BIM model to be constructed through the basic parameter evaluation model, and output an evaluation value;

[0078] Set an evaluation threshold, and output whether to obtain basic data in units of the structure tree model according to the comparison relationship between the evaluation threshold and the evaluation value.

[0079] Specifically, the construction of the basic parameter evaluation model includes:

[0080] Obtain the specific values of the basic parameters, construct a functional formula, and calculate the evaluation value based on the functional formula and the specific values;

[0081]

[0082] In the formula, G k is the evaluation value, ξ is the volume of the model built in the BIM model, K is the number of models built in the BIM model, Q a is the total cost of the current road project, Q b is the personnel cost of this project, and T is the total time of the current road project.

[0083] Setting the evaluation threshold includes:

[0084]

[0085] In the formula, G e is the evaluation threshold;

[0086] When the evaluation value is greater than or equal to the evaluation value threshold, output to obtain basic data in units of the structure tree model. When the evaluation value is less than the evaluation value threshold, output to obtain the target basic data on the structure tree according to the corresponding branch where the basic data is located.

[0087] In the above embodiments, the present solution provides another option, that is, according to the importance of the current road construction project, to determine how to select the basic data. Among them, the evaluation model set in the above solution can be understood as the quantified importance, that is, the evaluation value.

[0088] If the evaluation value is greater than or equal to the evaluation threshold, it indicates that the current road construction project is relatively important. In order to minimize the error, more data can be accepted, even if it may extend the entire modeling duration of BIM. In the current situation, the overall quality of the road construction project needs to be prioritized for consideration.

[0089] On the contrary, within the allowable range of error, the method provided by the present solution can be used to receive key data to improve the construction speed of the BIM model.

[0090] Secondly, in the evaluation of the BIM model, the present solution considers advantages such as volume, quantity, total cost, personnel cost, and time, which can comprehensively reflect the efficiency and effectiveness of the BIM model. First, the volume optimization of the BIM model can reduce the burden of file transmission and storage and improve collaboration efficiency. Secondly, the quantity of the model reflects the complexity and level of detail of the project. More models mean more comprehensive design and management. The optimization of the total cost reflects the advantages of BIM in project budget control and resource optimization. Through precise quantification and simulation, it can effectively reduce waste and additional expenses. The optimization of the personnel cost reflects the ability of BIM to improve design and construction efficiency. Through automated functions and collaboration platforms, the manpower requirement is reduced. In addition, the time advantage reflects the advantages of BIM in shortening the project cycle, optimizing the construction process, and reducing rework. By comprehensively considering these factors, the value of the BIM model can be better evaluated to provide support for project decision-making.

[0091] It should be noted that when calculating the parameters involved in this embodiment, the specific data is taken under the same unit standard, without unit operations, and the final result to be obtained is only a comparison between numerical values.

[0092] An exemplary embodiment of the present invention, the use of different symbols to mark the first connection node and the second connection node includes:

[0093] Obtain two basic data adjacent to the connection node, the basic data being primary data, secondary data, or tertiary data, and the connection node including a first connection node and a second connection node;

[0094] Select the first Chinese characters of the two basic data as a combination, and define the combination as the label of the current connection node; when a retrieval signal is received, obtain the Chinese characters of the basic data to be retrieved for database retrieval, retain the connection nodes corresponding to the Chinese characters of the basic data to be retrieved, and obtain a preprocessed database; perform a full-field retrieval on the preprocessed database to obtain a structure tree model corresponding to the basic data to be retrieved.

[0095] Through the above method, the retrieval speed can be further improved. The original database is reduced to a smaller range of preprocessed database, and a full-field retrieval is performed on the preprocessed database with a smaller range to improve the retrieval speed.

[0096] In a second aspect, a BIM-based road construction management system is configured to include:
