Description

Technical Field

[0001] The present invention belongs to the field of BIM technology, and specifically relates to a multi-dimensional space continuous maintenance method, system and medium for BIM. Background Art

[0002] In the existing construction engineering field, BIM is an important technical tool that can integrate multiple aspects of building data, including geometric models, material properties, engineering quantities and other information. In different stages of actual construction, different building data are concerned, and this information needs to be extracted and summarized based on different groups (work sections, flow sections, etc.). However, due to design changes and in-depth design, the information of components in BIM will be modified, and the component production plan and construction plan will also be adjusted, resulting in the inefficiency of extracting the data that needs to be concerned in actual construction. It is necessary to manually check the changes in components and groups in order to summarize the data.

[0003] The current approach has the following problems:

[0004] (1) Manual management and maintenance of component information consumes a lot of time and human resources. People are required to search, record, and update information component by component, which is not only inefficient but also prone to errors and omissions.

[0005] (2) Due to the intervention of human factors, manual management and maintenance of component information is prone to errors. People may forget to update the information of certain components, or incorrectly record data such as engineering quantities and coordinates, which affects the accuracy of the information.

[0006] (3) There is a lack of unified standards and a lack of unified methods for segmentation and aggregation. Different teams may use different methods to manage component information, resulting in inconsistent and confusing information, making collaborative work difficult and requiring more time and effort to coordinate and integrate information from different teams. Summary of the invention

[0007] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a multi-dimensional space continuous maintenance method, system and medium for BIM, which realizes the separation of component and space data through space division and mapping of components and space, and solves the problem of low efficiency in extracting data of interest at any time during construction.

[0008] According to one aspect of the present invention, a multi-dimensional space continuous maintenance method for BIM is provided, comprising:

[0009] Analyze the target BIM model to form a component database;

[0010] Automatically divide the space based on the component database to obtain building floor information;

[0011] Based on the building floor information and in combination with different construction dimensions, manually divide the space to form a number of space groups, each of which includes at least one subspace;

[0012] Based on the spatial three-dimensional information of each component in the component database, associating each component data to a corresponding subspace;

[0013] Select the required construction dimension to automatically map and summarize the space grouping corresponding to the construction dimension and the component data in each space grouping.

[0014] The above technical solution first parses the target BIM model to form a component database, then spatially divides the BIM model according to different dimensions to obtain different spatial groups, and associates each component with each subspace under the different spatial groups. During the construction process, the required component information can be quickly extracted based on different spatial groups, without the need to search and record each component one by one, thereby improving the efficiency of component management and making it less prone to errors and omissions.

[0015] Furthermore, the technical solution separates component data from spatial data by dividing the space of the BIM model into different dimensions. Changes in spatial data do not affect component data, and updates to component data do not affect spatial data. It only affects the association between components and space. In this way, when managing and maintaining components, the association between components and space can be referenced to check whether there are errors or omissions in component maintenance, thereby ensuring the accuracy of component maintenance.

[0016] Furthermore, the above technical solution abstracts floors, buildings, work sections, professional assembly lines, etc. into space groups and subspaces for unified management, thereby realizing a visual, editable, and data-extractable space management method.

[0017] As a further technical solution, after parsing to form a component database, it also includes: supplementing the construction data of each component in the component database component by component. Through this technical solution, the component information is improved or updated, and the supplemented or updated component data is stored in the component database.

[0018] As a further technical solution, when associating each component data with the corresponding subspace, it also includes: recording all data of the component, space grouping, and subspace and the relationship between the three to form a relationship mapping table.

[0019] The above technical solution provides a unified segmentation and aggregation method for component management by establishing a mapping relationship between components and space groupings and subspaces, so that the management of components is not affected by specific operators or teams, and ensures information consistency among collaborative teams.

[0020] As a further technical solution, the method further includes:

[0021] Filter out a component list corresponding to a space group or subspace according to the relationship mapping table;

[0022] The component list is checked, and when components are found to be missed, the missed components are added and mapped to the subspace.

[0023] The relationship mapping table can be used to quickly filter out the component list through each space group or subspace. It can also quickly check whether there are any missed components under a certain space group, allowing the administrator to manually add the missed components to the space.

[0024] As a further technical solution, after making design changes or deepening the design, it also includes: obtaining the changed component information and updating the component database, synchronizing the changed component information to the subspace under the corresponding space grouping, and re-associating the component data in the updated component database to the synchronized subspace.

[0025] Specifically, after a design change or in-depth design, the number, position, and properties of components may change, and these changes are synchronized to the component database; since components have changed, components may be added or deleted, it is necessary to synchronize the latest component information and spatial information, that is, after a design change or in-depth design, component updates and maintenance can be completed through data synchronization, without the need to manually search, record, and update each component.

[0026] Optionally, the method further comprises: manually adjusting the spatial information, and associating and updating the adjusted subspace with the component data to form a new association relationship.

[0027] As a further technical solution, when the geometric properties of a component change, it is determined whether the component data and the subspace need to be re-associated based on the spatial three-dimensional information of the component.

[0028] As a further technical solution, when manually dividing the space, it also includes:

[0029] Create spatial groupings based on preset dimensions;

[0030] creating at least one subspace within the spatial grouping;

[0031] highlighting at least one of the subspaces to determine whether the division of at least one of the subspaces is reasonable;

[0032] When it is determined that the division of at least one of the subspaces is reasonable, components are selected from the BIM model displayed by the lightweight engine and added to the divided subspaces, thereby completing the manual division of the subspaces within the space grouping.

[0033] The above technical solution takes into account that each construction stage and personnel have different concerns about data, and therefore adopts different spatial dimensions to manage data. In this way, when data needs to be extracted, by selecting the spatial dimension, the corresponding spatial grouping and subspace can be automatically mapped and summarized to form a corresponding component list for export, which greatly improves the efficiency of component extraction. Moreover, since it is a data-driven component extraction process, the accuracy of component extraction is also guaranteed.

[0034] As a further technical solution, when automatically dividing the space based on the component database, it also includes: automatically parsing and dividing the building floor information based on the building information, geometric information and number of floors information in the BIM model.

[0035] The above technical solution abstracts floors and buildings through automatic division, and manages them in a unified manner as a higher-level abstract object compared to the manual division result. On this basis, different spatial groups and subspaces are abstracted according to the spatial dimensions of different needs, and the aforementioned various abstract objects are managed in a unified manner. Changes in specific component data and spatial data are not considered, and only the relationship between abstract objects is considered, thereby realizing visual, editable, and data-extractable spatial management in an efficient and accurate manner.

[0036] According to one aspect of the present invention, a multi-dimensional space continuous maintenance system for BIM is provided, comprising:

[0037] A parsing module is used to parse the target BIM model to form a component database;

[0038] An automatic division module, used to automatically divide the space based on the component database to obtain building floor information;

[0039] A manual division module, used to manually divide the space based on the building floor information and in combination with different construction dimensions to form a plurality of space groups, each of which includes at least one subspace;

[0040] An association module, used for associating each component data to a corresponding subspace based on the spatial three-dimensional information of each component in the component database;

[0041] The extraction module is used to select the required construction dimension and automatically map and summarize the spatial grouping corresponding to the construction dimension and the component data in each spatial grouping.

[0042] Optionally, the system further includes an update module for supplementing and updating data of components in the component database; and a synchronization module for synchronizing the changed component data with its associated subspace after a design change or in-depth design.

[0043] Furthermore, the synchronization module is also used to associate and update the adjusted subspace with the component data after manually adjusting the spatial information to form a new association relationship.

[0044] According to one aspect of the present invention, a computer storage medium is provided, on which a computer program is stored. When the computer program is executed by a processor, the steps of the multi-dimensional space continuous maintenance method for BIM are implemented.

[0045] Compared with the prior art, the present invention has the following beneficial effects:

[0046] The present invention provides a method for organizing components and spaces of a BIM model, realizes the separation of component and space data, and abstracts construction dimensions such as floors, buildings, work sections, and professional flow sections into space groups and spaces for unified management through an interactive method of space division, thereby realizing visual, editable, and data-extractable space management.

[0047] The present invention provides a set of component and space update mechanisms to ensure that during the building construction process, the required component information can be quickly and accurately extracted based on different construction dimensions, providing data support for various subsequent planning and scheduling, and transforming the previous manual experience estimation into accurate and reliable planning and scheduling driven by data. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] Figure 1 The present invention is a flowchart of a method for continuous maintenance of a multi-dimensional space of BIM according to an embodiment of the present invention.

[0049] Figure 2 It is a schematic diagram of manual spatial division according to an embodiment of the present invention.

[0050] Figure 3 2 is a schematic diagram of data synchronization according to an embodiment of the present invention. DETAILED DESCRIPTION

[0051] Different stages of actual construction require different building data of interest, and this information needs to be extracted and summarized based on different groups (work sections, flow sections, etc.). However, due to the modification of component information in BIM during design changes or in-depth design, as well as the adjustment of production plans and construction plans, it is necessary to manually check the changes in components and groups in actual construction in order to summarize the data, which results in an extremely inefficient process for extracting the data of interest. Therefore, the present invention provides a multi-dimensional space continuous maintenance method, which is aimed at the BIM model, combines different construction dimensions to perform spatial division, abstracts the spatial groups and subspaces of different dimensions and associates them with components for mapping, and realizes the separation of components and spaces. At each stage of construction, component data can be automatically summarized according to spatial groups or subspaces, and the latest building data of current concern can be quickly extracted. In addition, plans can be flexibly viewed, plan differences can be compared, plans can be adjusted, etc., which improves the efficiency and accuracy of making construction plans.

[0052] It should be noted that:

[0053] The construction dimension refers to dimensions such as different stages of construction, splitting of subcontracting sections, splitting of assembly lines, and batch supply by material suppliers. It is mainly divided according to the different concerns of different people on construction data. It can be considered a division method generated by demand in construction.

[0054] Spatial grouping refers to the grouping formed according to the construction dimension. For any construction dimension, it can be divided into multiple spatial groups. For example, according to the construction dimension of flow section division, it can be divided into multiple spatial groups such as prefabricated flow section grouping, casting flow section grouping, masonry flow section grouping, etc.

[0055] Subspace refers to the next level of space grouping formed by further dividing each space grouping. For example, for the prefabricated flow section grouping, it can be further divided into flow section 1, flow section 2 and other subspaces.

[0056] Data of interest refers to data that people are concerned about and want to extract from the construction process. Different people want to extract different data of interest. If the traditional manual extraction method is used, there are problems of low extraction efficiency and easy errors. According to the method of the present invention, the corresponding spatial grouping can be selected according to the construction dimension of concern, and the corresponding component data can be automatically mapped and exported, thereby ensuring the extraction efficiency and accuracy.

[0057] In some of the processes described in the specification and claims of the present invention and the above-mentioned figures, multiple operations that appear in a specific order are included, but it should be clearly understood that these operations may not be executed in the order in which they appear in this article or executed in parallel. For example, step 1, step 2, etc. are only used to distinguish different operations, and the sequence number itself does not represent any execution order. In addition, these processes may include more or fewer operations, and these operations may be executed in sequence or in parallel. It should be noted that the descriptions of "first", "second", etc. in this article are used to distinguish different messages, devices, modules, etc., do not represent the order of precedence, and do not limit the "first" and "second" to different types.

[0058] The following will clearly and completely describe the technical solutions of various embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example 1

[0059] This embodiment provides a multi-dimensional space continuous maintenance method for BIM, which is used to realize the rapid and accurate extraction of different data of concern to different personnel during the construction process.

[0060] like Figure 1 As shown, the method includes:

[0061] Step 1: parse the target BIM model to form a component database.

[0062] Specifically, after obtaining the BIM model data, the model is parsed to form a component database, and the data required for subsequent construction, such as engineering quantities, process data, etc., are supplemented component by component in the component database as needed.

[0063] During the construction process, if a design change or in-depth design is performed, changes in components will occur, and the changes in components need to be synchronized to the component database.

[0064] Step 2: Automatically divide the space based on the component database to obtain building floor information.

[0065] Specifically, based on the building information, geometric information and number of floors in the BIM model, basic building floor information is automatically parsed and divided.

[0066] It should be noted that the geometric information here can be considered as the height data between floors. For example, after dividing the building floor information according to the building information, floor height and number of floors, the specific building and each floor of the building can be marked for later identification.

[0067] Step 3: Based on the building floor information and in combination with different construction dimensions, manually divide the space to form a number of space groups, each of which includes at least one subspace.

[0068] Each construction stage and personnel has different focuses on data, so different spatial dimensions are used to manage data.

[0069] Based on the actual construction situation of the project, construction management personnel manually select and divide the space in the 3D engine according to different dimensions such as different construction stages, subcontracting work sections, and batch supply by material suppliers. For example, they plan the production flow sections for PC components and the division of flow sections for concrete pouring.

[0070] like Figure 2 As shown in the figure, the process of creating space grouping and subspace specifically includes:

[0071] In the first step, the manager creates space groupings, such as prefabricated flow section groupings, casting flow section groupings, masonry flow section groupings, etc.

[0072] The second step is to create a subspace in a certain flow section dimension, such as creating casting flow section 01.

[0073] The third step is to render the model for display, where managers use a lightweight engine to visualize the current model.

[0074] Step 4: Highlight the subspace and check whether the subspace division is reasonable. You can highlight multiple subspaces at the same time to check whether the current space division is reasonable.

[0075] The fifth step is to select and add or delete components in the lightweight engine based on the current space grouping, add the components to the subspace, and complete the division of a subspace.

[0076] Step 6. Click on the subspace to view the components in the subspace.

[0077] Optionally, the manual division of the space may be performed on each floor of each building one by one.

[0078] Step 4: Based on the spatial three-dimensional information of each component in the component database, associate each component data with a corresponding subspace.

[0079] Based on the spatial three-dimensional information of the component, the system associates the component information with the subspace, which facilitates the subsequent query and summary of the component information based on the subspace. Due to the corresponding relationship between the subspace and the spatial grouping, the subsequent query and summary of the component information can also be based on the spatial grouping.

[0080] When constructing the associative mapping relationship between components and spaces, it is necessary to use a database to record all the data of components, space groups, and subspaces, and record the relationship between these three to form a relationship mapping table, so as to facilitate the subsequent rapid screening of the component list through each space group or space.

[0081] Furthermore, based on the relationship mapping table, it is also possible to quickly check whether there are any components missing in a certain space grouping. If there are any components missing, the administrator can manually add the missing components to the space.

[0082] Optionally, when the component attributes are changed, if there is no change in geometric attributes, the mapping relationship between the component and the space does not need to be changed. If there is a change in geometric attributes, it is necessary to determine whether the mapping relationship needs to be updated based on the three-dimensional spatial information.

[0083] It should be noted that the spatial three-dimensional information of the component is brought by the BIM model and can be obtained when the model is parsed. The present invention does not elaborate on the specific acquisition method thereof.

[0084] Step 5: Select the required construction dimension, and automatically map and summarize the space grouping corresponding to the construction dimension and the component data in each space grouping.

[0085] Construction management personnel select the corresponding construction dimension according to the current construction stage and needs. The system automatically maps and summarizes the current space grouping information and the component data in each space group or subspace, and exports it to the construction management personnel for use, such as querying the precast panel quantity information of each flow section.

[0086] As an implementation method, Figure 3 As shown in the figure, when a design change or in-depth design occurs, the number, position, and properties of components may change, and these changes need to be synchronized to the component database; and because components have changed, components may be added or deleted, so it is necessary to synchronize the latest component information with the spatial information, that is, to spatially associate components, and then the data of interest can still be extracted or queried according to the construction dimension.

[0087] Furthermore, if the relevant personnel manually adjust the spatial information, it is necessary to re-associate the adjusted spatial information with the component to facilitate data synchronization.

[0098] It should be noted that the implementation solution provided by the device to solve the problem is similar to the implementation solution recorded in the above method.
