Description

Technical Field

[0001] The present invention relates to the technical field of intelligent management of architectural engineering design results, and in particular to a collaborative management system and method for architectural engineering design results. Background Art

[0002] Design results documents are an indispensable prerequisite that must be followed in the construction of construction projects. They are also archived materials that must be delivered with the building entity after the completion of the project. They are the most important site management data throughout the entire life cycle of the project. The core of the design results is the construction drawings, including ancillary documents such as drawing review and design changes caused by process changes. Traditionally, design results such as construction drawings are mainly in the form of two-dimensional information. Engineering construction requires the two-dimensional information of the drawings to be expressed as a three-dimensional building entity. It involves many professional types and a large number of drawings. It is inconvenient to use and manage. It is difficult to communicate and coordinate drawings between different professions, and it is very easy to have problems such as errors and omissions. Therefore, design results management occupies a large amount of daily workload for technical personnel. At the same time, it is very dependent on the professional ability and engineering experience of technical personnel, and the overall work efficiency is low.

[0003] With the rise of BIM technology applications, the engineering design method of forward design and drawing based on BIM three-dimensional modeling has gradually become popular. Due to the three-dimensional visualization, parameterization and information capacity of building information models, compared with the traditional CAD two-dimensional design method, its design quality and efficiency have been greatly improved. In addition, with the development of digital concepts such as CIM, digital cities, and smart operation and maintenance, the dual handover mode of "digital products + physical products" based on BIM data will also be an inevitable development trend for the completion and delivery of projects. However, due to the technical conditions and professional barriers of BIM in software and hardware, the current design results documents mainly guide on-site construction in the form of coexistence of building information models and two-dimensional drawings. The complicated double arrangement of models and drawing files has increased the workload of on-site management. The imperfect data standards have also led to difficulties in BIM delivery. Therefore, the overall efficiency of design results management has not been significantly improved.

[0004] In recent years, a small number of BIM lightweight platforms for construction site building information modeling applications have appeared in the construction market, but most of them only support the disordered management of model files in the form of network disks. It is relatively rare to see the overall collaborative management of design results that are linked to models and drawings. In addition, the existing BIM lightweight platforms only support sporadic applications such as lightweight browsing, and rarely involve full-process and in-depth intelligent applications such as model collision, multi-party collaborative interaction, change retrieval, and integrated delivery of drawings and models. It is difficult to give full play to the technical advantages of building information models in digitalization and intelligence.

[0005] Therefore, construction sites are in great need of an intelligent and convenient artificial intelligence system to help solve the current problems of complicated design documents and chaotic management on construction sites, improve the efficiency of collaborative management of the entire process of design results data with the building information model as the core, and establish a digital data accumulation model for construction projects of "forward design - in-depth design - completion and handover". Summary of the invention

[0006] The purpose of the present invention is to provide a collaborative management system for architectural engineering design results to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above object, the present invention provides a collaborative management system for architectural engineering design results, comprising: The data architecture management module is used to create the data management organizational structure of the architectural engineering design results and set the architecture directory; A data input module, which is used to import design result files. The data input module includes a building information model input module and a two-dimensional design drawing input module, which are respectively used for batch importing building information models and two-dimensional drawing files of various disciplines and various data formats; The design achievement library module is divided into a personal achievement management library, a design achievement sharing library and an achievement receiving and downloading library according to the working status of the design achievements. The personal achievement management library is used to receive the design achievement files imported by the user through the data input module, and perform structured management according to the architecture directory set by the data architecture management module. The design achievement sharing library is used to receive the design achievement files shared by the user in the personal achievement management library, and the achievement receiving and downloading library is used to receive the design achievement files published by the user in the personal achievement management library; An interactive collaboration module, which is based on the design achievement files formed in the design achievement sharing library, and enables collaborative management and data transfer of design achievements among various disciplines through collaborative work; The data delivery module is used to receive the design achievement files in the published state in the achievement receiving and downloading library, establish the data delivery standard format with component-level association between the model and the drawing file through the drawing-model integration algorithm, and support the export of the design achievement digital delivery data package in the standard format.

[0008] In a preferred implementation, the data management organizational structure is a five-level structure system of achievement type, specialty, building, floor, and achievement file, and supports custom modification and setting of the architecture form.

[0009] In a preferred embodiment, in the personal achievement management library, the model and drawing files are automatically matched and an associated coupling relationship is established by starting the achievement association algorithm. The achievement association algorithm includes automatically retrieving the personal achievement management library files, performing AI semantic filtering on the structured model file set and the drawing file set respectively, and performing a While loop for each file according to the matching association rules of the two. First, the major to which the model / drawing belongs is identified and the model / drawing with the same major name is automatically matched to establish a first-level association. On this basis, the building to which the model / drawing belongs is identified and the model / drawing with the same building name is automatically matched to establish a second-level association. On this basis, the floor to which the model / drawing belongs is identified and the model / drawing with the same floor name is automatically matched to establish a third-level association. On this basis, the file name of the model / drawing is identified and the model / drawing with the same file name semantics is automatically matched to establish a fourth-level association. On this basis, the version number of the model / drawing is identified and the model / drawing with the same version number is automatically matched to establish a final association, thereby realizing a triple coupling of the drawing file ID and the model file ID, the corresponding file version numbers of the drawing and the model, and the same file history and the latest version ID.

[0010] In a preferred embodiment, when the design achievement file is changed, the file is updated and imported in the personal achievement management library and the historical version is overwritten. The system automatically compares the difference before and after the update and retrieves the specific content of the change through the change retrieval algorithm. The change retrieval algorithm automatically retrieves the geometric data and professional attribute data of the new and old versions of the building information model, and compares the new version component ID with the old version component ID to perform a component-by-component While loop. First, it is determined whether the component exists in the new version file. If not, the component data is obtained and marked as deleted data. On this basis, it is continued to be determined whether the component exists in the old version file. If not, the component data is obtained and marked as newly added data. On this basis, it is continued to be determined whether the size of the component in the new and old versions of the file matches. If not, the component data is obtained and marked as space size modification data. On this basis, it is continued to be determined whether the attribute information of the component in the new and old versions of the file matches. If not, the component data is obtained and marked as attribute modification data and a comparison modification attribute list is generated. After the While loop is completed, the new, modified, and deleted component set states are displayed in green, yellow, and red respectively, and a change retrieval record detail is generated.

[0011] In a preferred embodiment, in the design results sharing library, model files of different professions, buildings, floors, and data formats are assembled and integrated through a mold assembly algorithm. The mold assembly algorithm includes AI semantic recognition based on the input professional text or voice, automatically selecting the corresponding building information model file set, retrieving all component information in each model file required for mold assembly, and respectively obtaining the component's geometric information, direction position matrix, and professional attribute information, wherein the component's geometric information is combined with point linear data to form a multi-point triangular surface, a component space three-dimensional view is generated, the component's professional attribute information is used to generate each professional attribute position point set, the component's direction position matrix is ​​pushed to the component space three-dimensional view to form a 3D rendered three-dimensional model, and pushed to the professional attribute position point set to automatically correct the model component's direction position, and finally integrated to generate a mold assembly file for the entire component set.

[0012] In a preferred embodiment, in the design results sharing library, a collision check algorithm is used to quickly locate the conflict problems between different model files. The collision check algorithm automatically retrieves the model information in the selected mold file, parses all component geometric properties and component position properties, renders the model component geometry at points, lines and surfaces and forms a component bounding box. The While loop checks the object position and shape boundaries of each model component in discrete steps, determines whether the component bounding boxes are in an intersecting state, calculates the collision point for the intersection state and forms a collision record.

[0013] In a preferred embodiment, the interactive collaboration module includes a collaborative work environment module and a collaborative work result module, wherein the collaborative work environment module realizes the creation and application of instant messaging conferences through a collaborative work environment algorithm. The collaborative work environment algorithm supports manual creation of collaborative work tasks, selection of participant IDs and collaborative outcome files, generation of unique work codes and initiation of meetings. The meeting generates three windows for model online collaboration, drawing online collaboration, and instant messaging, and information linkage is carried out between them.

[0014] In a preferred embodiment, the collaborative work result module realizes the intelligent generation of instant messaging conference records through a collaborative work result algorithm. The collaborative work result algorithm supports automatic classification of meeting data packets after the collaborative work task is completed. For model and drawing viewport records, the three-dimensional model information is automatically converted into a two-dimensional image format. For model and drawing annotation records, it is automatically determined whether there is two-dimensional information and the two-dimensional information is converted into an image format. The rest is converted into text information. The text voice, meeting topic, participant ID, and built-in meeting minutes template of instant messaging are converted into text information as a whole.

According to the conclusion of the collaborative work task, if the design results need to be changed, after the file content is updated, the historical version of the file is manually withdrawn and shared, and the updated file is imported into the personal achievement management library and overwrites the historical version. The system starts the change retrieval algorithm, automatically compares the new version of the file with the old version and retrieves the specific content and location of the change. The status of the added, modified, and deleted component collections is highlighted in green, yellow, and red, and the change retrieval record details are generated; S10, looping through steps S3 to S9 until the design result is finalized.

[0016] In a preferred embodiment, the following steps are also included: S11. According to the conclusion of the collaborative work task, if the design results are finalized, the finalized files in the shared state in the personal results management library will be published.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention are described clearly and completely below. The embodiments of the present invention and all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0021] Example 1 like Figures 1 to 8 As shown, the collaborative management system for architectural engineering design results of the present invention includes: a data architecture management module 301, a data input module 302, a design result library module 303, an interactive collaboration module 304 and a data delivery module 305.

[0022] Specifically, the data architecture management module 301 is used to create a data management organizational structure for architectural engineering design results and set the architecture directory. By setting a multi-level structure tree of the design results library, the prerequisites are provided for the structural and parametric management of design results and a series of subsequent intelligent applications. The default architecture of architectural engineering design results management is a five-level structure system of results type (model / drawing, etc.), profession (architecture / structure / mechanical and electrical, etc.), building, floor, and results file, and it also supports custom modification and setting of architecture forms.

[0023] The data input module 302 is used to import the design result files. The data input module includes the building information model input module 321 and the two-dimensional design drawing input module 322, which are respectively used for batch importing the building information model and two-dimensional drawing files of various disciplines and data formats. By manually selecting the architecture directory to which the design result files belong, the system automatically classifies them into the hierarchical database for structured storage, and automatically converts the building information model and two-dimensional drawings into IFC format synchronously and lightly for online engine processing and application. At the same time, the source files are still stored in the database in the original data format for subsequent download and use.

[0024] The design achievement library module 303 is divided into a personal achievement management library 331, a design achievement sharing library 332 and an achievement receiving and downloading library 333 according to the working status of the design achievements. The design achievement library module is not only a database for storing various design achievement files, but also provides conditions for the circulation and transmission of design data between various professions, realizing the whole process and intelligent collaborative management of design achievements. Among them, the personal achievement management library 331 is used to receive the design achievement files imported by the user through the data input module, and perform structured management according to the architecture directory set by the data architecture management module. The working status of the initially imported design achievement files is in draft, which is only visible to the user. Only after the file is shared can it be interactively applied by other professionals.

[0025] In the personal achievement management library 331, the achievement association algorithm is started to realize automatic matching between the model and the drawing file and establish an associated coupling relationship, such as Figure 2 As shown, the achievement association algorithm includes automatically retrieving personal achievement management library files, performing AI semantic filtering on the structured model file set and drawing file set respectively, and performing a While loop for each file according to the matching association rules of the two. First, the major to which the model / drawing belongs is identified and the model / drawing with the same major name is automatically matched to establish a first-level association. On this basis, the building to which the model / drawing belongs is identified and the model / drawing with the same building name is automatically matched to establish a second-level association. On this basis, the floor to which the model / drawing belongs is identified and the model / drawing with the same floor name is automatically matched to establish a third-level association. On this basis, the file name of the model / drawing is identified and the model / drawing with the same file name semantics is automatically matched to establish a fourth-level association. On this basis, the version number of the model / drawing is identified and the model / drawing with the same version number is automatically matched to establish the ultimate association, realizing the triple coupling of the drawing file ID and the model file ID, the corresponding file version numbers of the drawing and the model, and the same file history and the latest version ID.

[0026] When the design result file is changed, the file is updated and imported in the personal result management library and the historical version is overwritten. The system automatically compares the difference before and after the update and retrieves the specific content of the change through the change retrieval algorithm, such as Figure 3 As shown in the figure, the change retrieval algorithm automatically retrieves the geometric data and professional attribute data of the components of the new and old versions of the building information model, and compares the component ID of the old version with the component ID of the new version to perform a While loop for each component. First, it is determined whether the component exists in the new version file. If not, the component data is obtained and marked as deleted data. On this basis, it is further determined whether the component exists in the old version file. If not, the component data is obtained and marked as new data. On this basis, it is further determined whether the dimensions of the component match in the new and old versions of the file. If not, the component data is obtained and marked as space dimension modification data. On this basis, it is further determined whether the attribute information of the component matches in the new and old versions of the file. If not, the component data is obtained and marked as attribute modification data and a comparison modification attribute list is generated. After the While loop is completed, the status of the component set of new, modified, and deleted components is displayed in green, yellow, and red respectively, and the change retrieval record details are generated. Compared with the traditional method of manually comparing the changed content, the change retrieval algorithm has greatly improved its work efficiency and accuracy. At the same time, the change retrieval record is circulated with the design results, which is convenient for other professionals to quickly view the changed content.

[0027] The design achievement sharing library 332 is used to receive the design achievement files shared by the user in the personal achievement management library, and the achievement receiving and downloading library is used to receive the design achievement files published by the user in the personal achievement management library. The achievement files in the shared state are visible to all project members, support online circulation applications between various disciplines, and provide a data source for collaborative interaction. At this time, the design achievements are in the collaborative stage of various disciplines and have not been finalized. There may be design changes and they cannot guide on-site construction.

[0028] In the design results sharing library 332, the model files of different disciplines, buildings, floors, and data formats are assembled and integrated through the mold assembly algorithm, such as Figure 4 As shown, the mold assembly algorithm includes AI semantic recognition based on the input professional text or voice, automatically selecting the corresponding building information model file set, retrieving all component information in each model file required for mold assembly, and respectively obtaining the component's geometric information, direction position matrix, and professional attribute information, wherein the component's geometric information is combined with point linear data to form a multi-point triangular surface, a component space three-dimensional view is generated, the component's professional attribute information is used to generate each professional attribute position point set, the component's direction position matrix is ​​pushed to the component space three-dimensional view to form a 3D rendered three-dimensional model, and pushed to the professional attribute position point set to automatically correct the model component's direction position, and finally integrated to generate the mold assembly file of the entire component set.

[0029] In the design results sharing library 332, the collision detection algorithm is used to accurately and quickly locate the conflict problems between different model files, such as Figure 5As shown, the collision check algorithm automatically retrieves the model information in the selected mold file, parses all component geometric properties and component position properties (three-dimensional coordinates), renders the model component geometry at points, lines and surfaces and forms a component bounding box, and checks the object position and shape boundaries of each model component in discrete steps in a While loop to determine whether the component bounding boxes are in an intersecting state, calculates the collision point (including model component ID, component name, coordinates, etc.) for the intersection state and forms a collision record.

[0030] The achievement receiving and downloading library 333 is used to receive the design achievement files such as building information models and two-dimensional drawings published by users in the personal achievement management library. After the achievement files in the sharing state are finalized through the collaboration of various professionals, the user changes the file from the sharing state to the publishing state in the personal achievement management library. The achievement files in the publishing state enter the achievement receiving and downloading library and are visible to all project members. At this time, the file supports local downloading by various professionals for guiding on-site construction. At the same time, the published design achievements are automatically transferred to the data delivery module 305 as the completion delivery data.

[0031] The interactive collaboration module 304 is based on the design result files formed in the design result sharing library, and through collaborative work, the design results are collaboratively managed and data transferred between various disciplines. The interactive collaboration module includes a collaborative work environment module 341 and a collaborative work result module 342. The collaborative work environment module realizes the creation and application of instant messaging conferences through a collaborative work environment algorithm, such as Figure 6 As shown in the figure, the collaborative work environment algorithm supports manual creation of collaborative work tasks, selection of participant IDs and collaborative output files (including mold-joining files and models, drawings, collision check records, etc. linked to them), generation of unique work codes and initiation of meetings. The meeting generates three windows: model online collaboration, drawing online collaboration, and instant messaging, which are linked to each other. Participants can review mold-joining models, collision records or other selected model files in the model online collaboration window, and support various annotation operations on the model interface; they can review drawings associated with the model in the drawing online collaboration window, and support various annotation operations on the drawing interface; the instant messaging window can receive / send text and voice messages, model or drawing annotation interface views in real time, click to view other people's model or drawing annotation views, and the model or drawing online collaboration window of the participant will automatically jump to the viewport and display its annotation content, thereby realizing real-time collaboration based on the same model / drawing perspective and multi-party free operation under the principle of non-shared screen. After the instant messaging meeting, the meeting minutes are automatically generated as collaborative work output files.

[0032] The collaborative work result module realizes the intelligent generation of instant messaging conference records through the collaborative work result algorithm, such as Figure 7As shown, the collaborative work result algorithm supports automatic classification of meeting data packages after the collaborative work task is completed. For model and drawing viewport records, the three-dimensional model information is automatically converted to a two-dimensional image format. For model and drawing annotation records, it is automatically determined whether there is two-dimensional information and the two-dimensional information is converted to an image format. The rest is converted to text information. The text voice of instant messaging, meeting topics, participant IDs, and built-in meeting minutes templates are converted to text information as a whole. The system integrates text and image information through AI semantic recognition, automatically generates meeting minutes files, and supports download and export in various formats. At the same time, it automatically identifies model drawing problem descriptions in the text to generate model drawing correction work tasks, determines the person responsible for the task and automatically sends it to the person responsible’s account interface, realizing closed-loop management of collaborative design results.

[0033] The data delivery module 305 is used to receive the design achievement files in the published state in the achievement receiving and downloading library, establish the data delivery standard format of the component level association between the model and the drawing file through the image-model integration algorithm, and support the export of the design achievement digital delivery data package in the standard format. Figure 8 As shown, the drawing-model integration algorithm supports automatic retrieval of the results receiving download library. The While loop reads the as-built version of the building information model file and identifies whether there is an associated drawing file. If so, the While loop is used to automatically parse the model components and drawing layer lines, respectively, to obtain the geometry and professional characteristics of the component model and drawing layer lines. The While loop model and drawing characteristic library is used to match the bidirectional association between the component model and the drawing layer lines, so as to realize the positioning of the component model to display the corresponding drawing layer line effect (and vice versa), and generate the model-drawing integrated delivery data package based on the drawing-model association integration.

[0034] Example 2 like Fig. 9 As shown, the present invention also provides a method for collaborative management of architectural engineering design results, comprising the following steps: Step S1. Create a data management organizational structure for design results. By default, a five-level structured system is built: result type (model / drawing, etc.) → profession (architecture / structure / mechanical and electrical, etc.) → building → floor → result file. Custom modification and setting of the architecture format are also supported.

[0035] Step S2, select the architecture directory to which the design achievement files belong, batch import and store the design achievement files including building information models and two-dimensional drawings in the personal achievement management library, and the system automatically synchronizes and converts them into IFC format.

[0036] Step S3: In the personal achievement management library, start the achievement association algorithm to automatically match the model with the drawing file and establish an associated coupling relationship.

[0037] Step S4: Share the design achievement files in the draft state in the personal achievement management library. The shared design achievement files enter the design achievement sharing library and are visible to all project members, and support online collaborative circulation applications between different disciplines.

[0038] Step S5, input the text description of the basic information required for mold joining, including mold joining profession, building, and floor information, start the mold joining assembly algorithm, automatically select the corresponding building information model file, complete the assembly and integration of model files of different professions, buildings, floors, and data formats, and form a mold joining file.

[0039] Step S6, select the mold-joining file that needs to be searched for conflict problems, start the collision check algorithm, automatically search and locate all collision points between the model components in the mold-joining file, generate a collision check record, and click the record item to automatically jump to the model collision position and highlight it.

[0040] Step S7, create a collaborative work task, enter the meeting topic, select the participants, and the joint mold file for collaboration (automatically bring out the linked models, drawings, collision check records, etc.), start the collaborative work environment algorithm, review the model, drawings, collision records and other achievement files in the model / drawing online collaborative window, and perform annotation operations in the viewport interface. Send and receive text and voice messages, model / drawing annotation views in real time in the instant messaging window, click to view other people's annotation views, and your own model / drawing online collaborative window will automatically jump to the viewport location and display its annotation content.

[0041] Step S8, end the collaborative work task, start the collaborative work result algorithm, automatically collect meeting record data, generate a standard format meeting minutes file and support multiple formats for downloading, identify the model drawing problem description in the meeting record to generate a correction work task, automatically determine the task responsible person and send it to the responsible person's account interface.

[0042] Step S9. According to the conclusion of the collaborative work task, if the design results need to be changed, after the file content is updated, the historical version of the file is manually withdrawn and shared, and the updated file is imported into the personal achievement management library and overwrites the historical version. The system starts the change retrieval algorithm, automatically compares the new version of the file with the old version and retrieves the specific content and location of the change. The status of the newly added, modified, and deleted component sets is highlighted in green, yellow, and red, and a change retrieval record detail is generated.

[0043] Step S10: loop through steps S3 to S9 until the design result is finalized.

[0044] Step S11, according to the conclusion of the collaborative work task, if the design results are finalized, the finalized files in the shared state in the personal results management library will be published, and the published design results files will be entered into the results receiving and downloading library and visible to all project members, supporting local downloads by various disciplines for guiding on-site construction, and automatically transferred to the data delivery module as completion delivery data.

[0045] Step S12: Start the image-model integration algorithm to establish a data delivery standard format for component-level association between the published model and the linked drawing file, so as to display the corresponding drawing layer lines in the positioned component model (or vice versa). The system automatically exports the delivery data package for download and delivery based on the data delivery standard format of the image-model integration.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
