Description
Technical Field
The invention belongs to the technical field of engineering construction information, and particularly relates to a method and a device for organizing a BIM model decomposition structure, electronic equipment and a storage medium.
Background
Under the background that the digitization degree of the modern engineering construction field is continuously improved, the BIM (Building Information Modeling, building information model) model is used as an efficient information carrier with visualization, coordination, simulation, optimality and accuracy, and has a great number of applications in the whole engineering construction process, including three-dimensional rendering display, rapid and accurate calculation, accurate planning, virtual construction collaboration, collision inspection and the like.
Because the requirements of each business work on model information acquisition are different in the engineering construction process, the organization and division modes and division precision of each business scene on the BIM model are often different. When a designer creates a bridge model, the bridge model is usually split in sequence according to the level of "bridge-web-part-split-span-structure-member". However, in the case of engineering quantities, the division of the layers and the precision of the "bridge-division-framing-part-component-material" type may be organized. The model organization division and the precision difference under each scene can make the corresponding relation of the model between each stage difficult to find, which causes trouble to the data management of the model and the transmission and the repeated use in each scene, thereby not well playing the advantages of the coordination and the optimality of the BIM in the whole engineering construction process.
At present, a clear model organization dividing structure is lacking, so that the application requirements under all business scenes can be met at the same time, the most common processing method is that each business scene independently creates a model meeting the requirements according to respective model organization modes, but the method has the following problems:
1) A large number of repetitive works are generated. For the same engineering object, different business systems all need to create models, but a large amount of repeated data, such as geometric information, material types and the like of the models, must exist between the models, which inevitably causes a large amount of repeated creation work.
2) Data transfer between different stages and between different service systems in the same stage of the industry is difficult. Because each service system only establishes a model aiming at the requirements under the own service scene, the mapping relation between the model organization and the corresponding level data among the service systems is necessarily different, and even if the model establishment is carried out by adopting a uniform data format, the different mapping relation between the model and the corresponding level data can cause trouble to the data transmission and reading.
3) The simultaneous existence of multiple sets of models is inconvenient for data management. Different business scenes create different models, the data stored by the different models are different, the models are difficult to correlate with each other, and a plurality of sets of model data are required to be managed and maintained at the same time, so that the inconvenience of data management is caused.
4) The whole process application of a set of models cannot be realized, and the advantages of BIM are difficult to embody. For different modes of creating and maintaining different models of different services, each service system is difficult to coordinate and optimize through the models, cannot form a unified data source, and is difficult to embody the advantages of BIM technology in the whole engineering process.
Therefore, in the field of information technology of engineering construction, a solution suitable for tissue division and application of BIM model of engineering whole-process construction is needed.

Detailed Description
For a further understanding of the present invention, preferred embodiments of the invention are described below in conjunction with the examples, but it should be understood that these descriptions are merely intended to illustrate further features and advantages of the invention, and are not limiting of the claims of the invention.
The embodiment of the invention provides a BIM model organization method for a plurality of decomposition structures in the whole engineering process, which is shown in fig. 1 and comprises the following steps:
s1, creating a BIM model with granularity of a component level, and inputting and perfecting attribute information of the component, wherein the attribute information comprises initial attribute information and supplementary attribute information.
The Building Information Model (BIM) is a basic building element, which is a series of building elements that are interrelated in three-dimensional space and that together perform a building function. The components may represent building partitions, structural columns, point loads, beams, beam pads, rebars, sewer pipes, and the like. The components have certain shapes and sizes, and in addition, the components have the characteristics of materials, concrete strength, names and the like.
In the embodiment of the invention, the BIM model creation process is required to be carried out according to the granularity of the component level. For example, one of the rectangular piers is created, the foundation adopts a pile foundation, and as shown in fig. 2, the component granularity level comprises 2 piers, 1 bridge column tie beam, 2 foundation piles, 1 pile tie beam, 4 pile foundations and 2 cushion layers, and the total is 12 components.
The data of the BIM model includes geometric data and non-geometric attribute data. Geometric data refers to data related to geometric characteristics of the building model, such as shape, size, etc. Non-geometric attribute data, also called attribute information, including positioning information, material information, construction requirements, category classification, etc. of the BIM model, generally has two input modes:
1) Direct input: directly used as parameter input when the model is created, and is generated and bound together with the BIM model. For example, positioning information, material information, etc. may be directly input;
2) Supplementary hooking input: the attribute information is additionally hung on the model after the BIM model is built. For example, the construction requirement, time information, and the like are supplemented with the hooking input.
The attribute information is directly bound with the component, and when the attribute information is created, no fixed hierarchical dependency relationship exists between the attribute information of the required model, namely, the attribute information is in parallel relationship.
The attribute information is divided into initial attribute information and supplementary attribute information. The initial attribute information is attribute information input at the time of building a component of the BIM, and is generally directly input. The supplementary attribute information is other attribute information of the BIM component except the initial attribute information, and may be input gradually at each stage of engineering construction, and usually, the supplementary hooking mode is adopted.
In the whole engineering construction process, as the engineering stage is continuously advanced, the LOD (Level of Development, development fineness grade) requirement of the BIM model is continuously improved, and the attribute information of the model is necessarily required to be continuously increased to improve the precision so as to meet the requirement of a business scene, and the mode of supplementing and hanging the attribute information is an important input mode in the later stage.
The specific operation of step S1 in the embodiment of the present invention is as follows:
s11, building a component of the BIM model, generating a component ID and a component name, and inputting geometric data and initial attribute information of the component.
The building block of the BIM model requires the input of some information as follows.
1) Component ID.
When building components of the BIM model, each component needs to generate an ID code of the corresponding component according to the industry code standard plus the actual modeling parameters, and each component ID is unique in the BIM model.
For example, one component ID code in FIG. 3 is "18-04.04.02.00-0010037203001". The ten-bit code (without separator) is "18-04.04.02.00", which is the code of bridge pier according to the highway engineering information model unification Standard (Q/CCCC GL 501-2019). In the latter half, "001" represents a bridge number, "0037" represents a joint number, "2" represents a frame number, "03" represents a site, and "001" represents a member number.
2) Name of the component.
The component name is similar to the name of a person and can be repeated. The component ID is similar to the ID card number, is uniquely corresponding and is not repeatable. The component ID is used for the system program to inquire and locate the component, and the component name is used for front-end display, so that a user can inquire and locate the component conveniently, and the component is displayed in the model organization structure tree by the component name later.
The component name is generally selected from 2 to 3 attribute combinations, for example, a combination of "component type+component number+pile number" is selected for naming, and the component name is "pier 1 (k22+66)", wherein "pier" is "component type", "1" is "component number", and "k22+66" is "pile number".
3) Geometric data.
Although important for building BIM, the geometric data is not used as a basis for the subsequent BIM model tissue classification in the embodiment of the invention, and therefore, the details are not described.
4) Initial attribute information.
The initial attribute information is attribute information input at the time of building a component of the BIM. For example, fig. 3 is an example of attribute information of a component, and a component ID and a component name are also included in the table for associating the component. Fig. 3 includes a plurality of pieces of attribute information, each piece of attribute information including an attribute name, an attribute group, a type, an attribute value, whether filling is necessary, and the like. The last column of the attribute information listed in fig. 3 is "whether or not it is necessary to be filled" indicating whether or not it is necessary to be filled. The "whether to fill" field of the attribute information is used to distinguish whether the attribute is a fill-in attribute or an optional attribute, which can be used for subsequent attribute classification. The attribute groups are groups of several attributes, and the attribute properties and functions included in each attribute group are approximate. For example, several pieces of attribute information within the "identity information" attribute group are used to record each level of identity information of the component.
S12, inputting the supplementary attribute information of the BIM model component.
As engineering projects develop, supplemental attribute information needs to be added to the components of the BIM model. And inputting attribute information required by different business scenes according to LOD precision required by different stages of engineering construction.
The input supplemental properties may be divided into batch properties and proprietary properties.
1) Batch properties: the attribute values input in batch can be prepared in a batch processing mode, when attribute contents are input, the types of attribute information and whether the attribute information is a necessary item are defined at the same time, and then the batch attribute hooking is completed in a mode of acquiring the component ID.
2) Proprietary properties: only attribute information is added to a certain component, and the special attribute is often that the special attribute information cannot be a hierarchical option for subsequent organization management, such as "coating description" of the bridge pier in fig. 4.
Fig. 4 illustrates the data needed to be supplemented in different business scenarios, wherein the attribute information of the attribute group "design information" can be used for engineering metering, including concrete usage, rebar material. The attribute information of which the attribute group is "construction information" can be used for construction management such as construction process, construction mode, construction time. The above attributes can be added uniformly by a batch addition attribute tool. In the construction management process, there is a requirement for "coating explanation" attribute information of the pier, but there is no requirement for pile foundation, so that the coating explanation is added to the pier as a special attribute by using a separate adding tool. Since the proprietary attribute is not an attribute that all components have, its "no to fill" field is no, and thus cannot be used as a basis for the organization management of the subsequent BIM model components.
S2, creating a BIM model organization mode service scene, and setting a service scene name.
Each scene, in turn, generates a corresponding model texture tree, corresponding to a way of organizing the BIM model. The model organization structure tree organizes the components in the BIM model in an organization mode expected by a service scene to form a tree structure, and the terminal nodes of the tree correspond to one component. In order to facilitate distinguishing and memorizing, when a scene is newly established, a proper scene name is set. For example, a scene name "design scene hierarchy" may be set for dividing the BIM model according to the requirements of engineering design. An "EBS decomposition" scenario may also be provided for dividing the BIM model according to the requirements of EBS (Engineering Breakdown Structure, engineering decomposition structure) decomposition. Or setting an engineering quantity list decomposition scene for dividing the BIM model according to the statistics of the engineering quantity list or the charging requirement.
S3, setting the number of the levels of BIM model organization under the service scene, and selecting the attribute name of each level for hierarchical classification.
In order to meet the demands of BIM model organization in the scene, the BIM model is flexibly decomposed, and the method is operated according to the following steps:
1) A first level attribute name is set. The attribute name may be selected from all of the mandatory attributes.
2) And adding the next grade, and setting the attribute name of the next grade.
3) The next classification is continued to be added until the decomposition requirement is met.
4) When a certain grade is not needed, the grade can be deleted, and the lower-layer grade automatically moves upwards.
For example, in fig. 5, a bridge hierarchy is shown, where the left side is an interface for editing a scene and hierarchy, the right side is a property name option after each level is pulled down, and the name of all necessary attribute information in the BIM model is contained in the bridge hierarchy. And adding a first hierarchy to a newly-built scene with the scene name of 'design scene hierarchy', pulling down to select the attribute name for the hierarchy of the layer, and selecting the mandatory attribute of 'bridge name', thereby completing the addition of the first hierarchy. The addition of subsequent levels is then completed in turn in such a way.
The embodiment of the invention can adjust the completed hierarchy, such as reselecting a new attribute name or deleting the hierarchy. After deleting a certain middle hierarchy, the hierarchy level of the subsequent hierarchy is automatically adjusted. As in the example of fig. 5, the third level is deleted, the original fourth level is automatically changed to the third level, the fifth level is changed to the fourth level, and so on. The method can increase and decrease the grading in the scene without limitation.
For example, "design scene classification" in fig. 5 is six-level division: 1) "bridge name"; 2) "bridge width"; 3) "site"; 4) "split"; 5) "line number" of dividing and crossing; 6) "structural type". The other scenes of EBS decomposition and engineering quantity list decomposition are different from the design scene classification, and for BIM model projects with different classification requirements, the requirements can be met through adding scenes and classification, and the definition of the scenes and the definition of the classification can have higher degree of freedom.
And S4, generating a model organization structure skeleton under the service scene according to the attribute names classified in a grading way.
The model organization structure skeleton is a tree structure formed by dividing component attributes in the BIM according to hierarchical classification attributes, and is called as a model organization structure skeleton at the moment because the tree structure does not contain component information.
After determining the classification of the service scene, according to the hierarchical order and attribute names of the classification, the method operates as follows:
1) And counting attribute information of all components of the BIM model, and finding all attribute values under the attribute names of the first level.
2) Each attribute value under the hierarchy attribute name is taken as a branch under the hierarchy.
3) All attribute values under the next level attribute name are read, each attribute value being a sub-branch of the branch.
4) Repeating the previous step until all the layers are operated to form the model organization structure skeleton.
For example, the pier elements shown in fig. 3 are divided according to the classification in fig. 5. The attributes of fig. 5 are classified as "bridge name-bridge width-part-split-cross line number-structure type". The process of generating the model organizational structure skeleton is as follows, as shown in FIG. 6:
1) And searching the attribute value under the attribute of 'bridge name' in the attribute list of all the component information, wherein only one of the attribute values is 'bridge A', and taking the bridge A as the only branch of the first layer of the model organization structure tree.
2) Under the branch of the bridge A, according to the attribute name of the second stage, searching all attribute values in the component information list to obtain two attribute values of a left-width and a right-width, and forming two branches under the bridge A.
3) And searching all attribute values of the attribute list of the lower component of the branch under the same left branch according to the third-level attribute name part to obtain three value types of an upper structure, a lower structure and an auxiliary structure, thereby forming three branches under the left branch. Such three branches are likewise provided under the "right panel". Limited to graphic space, fig. 6 shows only the "left panel".
4) And the rest is divided into the last stage, so that a complete six-layer branch framework is formed, and the model tissue structure framework shown in fig. 6 is obtained.
S5, adding components for the terminal nodes of the model organization structure skeleton, recording component IDs, displaying component names and generating a model organization structure tree.
The model organizes the terminal nodes of the structural skeleton to correspond to an attribute value list, and all attribute values from the tree root to the terminal nodes are included. And finding out the components meeting the attribute value list, dividing the components with the same attribute value list under the same terminal node of the model organization structure skeleton, displaying the components under the nodes of the model organization structure skeleton by the component names, generating a model organization structure tree, and recording the IDs of the components on leaf nodes of the tree.
For example, the model organization structure skeleton terminal node is "bridge a-left-lower structure-37 th union-129 th bridge pier", corresponding to an attribute value list containing six attribute values, finding all the components satisfying the attribute values, finding 12 components in total, reading the IDs and the component names of the components, and displaying the component names under the model organization structure skeleton terminal node to form a model organization structure tree shown in the left graph of fig. 7.
After the model organization structure tree is generated, the model organization structure tree can be inspected. And checking the number of the divided components according to the generated model organization structure tree, and checking whether the model organization structure tree can be completely mapped to the components of the BIM model, so that the corresponding relation between the model organization structure tree and the components is ensured not to be lost or conflict, and the division requirements of the service scene are ensured to be met.
When the number of components on the model organization structure tree is inconsistent with the number of division requirements, it is generally necessary to check whether the attribute information of the components is missing or erroneous due to incorrect setting of the attribute information for hierarchical classification.
For example, after the classification operation, all 12 components in the structure tree of the left graph model of fig. 7 have proper positions without any loss, and the structure form meets the division requirement of the service scene.
S6, correspondingly associating the components of the model organization structure tree with the components of the BIM model through the component ID.
In the process of forming the model organization structure tree in the above steps, the component ID is already stored in the model organization structure tree, and because of the uniqueness of the component ID, the model organization structure tree can easily query the corresponding component through the component ID, so as to realize the corresponding association between the model organization structure tree and the component in the BIM model. Different model organization structure trees can be correspondingly associated with the same component through IDs.
For example, one of the components in the left-hand diagram of FIG. 7, shown with the component name "pier 1 (K22+66)", corresponds to a component ID of "18-04.04.02.00-0010037203001", by which components on the model organizational tree can be mapped to components in the BIM model.
Aiming at different service scene requirements, the embodiment of the invention can arrange the model organization structure tree of the corresponding scene. Through the steps S2-S6, the construction of the model organization structure tree under the service scene is completed. When multiple division scenes are required to be established through BIM, repeating the steps S2-S6 for each scene to obtain a model organization structure tree under each scene.
Fig. 7 shows a model organization structure tree obtained by grading two piers in a left-right width according to different scenes, and the final divided result is displayed in the figure by the name of a member. The left side is a model organization structure tree obtained under the design scene classification, and the right side is a model organization structure tree obtained under the engineering quantity list decomposition scene classification. The left side structure tree is classified into six stages according to bridge name-bridge width-part-branch line number-structure type, all the components of each bridge pier are divided together, and the left bridge pier and the right bridge pier are already divided in the second stage. The model organization structure tree on the right side is classified in five stages according to the bridge name-part-branching-bridge width-component type, all components in each bridge pier are not divided together, and the left bridge pier and the right bridge pier are separated in the fourth stage bridge width.
After generating a plurality of model organization structure trees, the model organization structure trees can be freely switched, and the BIM model is subjected to organization management of different dimensions.
And managing BIM models by adopting different model organization structure trees, such as displaying, hiding, deleting, editing and the like. The model organization structure tree shows the names of the components, the selected component names can find the corresponding component IDs, and the components corresponding to the BIM model are found through the component IDs. The model organization structure tree is used for displaying, hiding, editing and the like of the components by using a geometric engine of BIM software after the components are found and selected through the component ID, and can be used as an input port of an operation command. When the components are deleted, the model organization structure tree is automatically refreshed, and the ID and the name of the deleted components are removed to obtain a new model organization structure tree. The BIM model can be managed by different model organization structure trees, and the switching of the model organization structure tree does not generate substantial operation and influence on components, and only jumps to different model organization structure tree pages for management.
