[0002] During the traditional construction process, viewing the drawings and models of a building requires relying on different devices and platforms, which is extremely inconvenient to operate. Construction workers at the construction site often need to frequently switch between paper drawings, electronic drawing software, and model software.

[0004] However, the existing drawing-model linkage systems can only achieve simple simultaneous display of drawings and models, and the deep integration and interaction reliability of drawings and models are relatively low. For complex building structures and mechanical and electrical systems, it is difficult for construction workers to quickly and accurately find the detailed information in the corresponding areas of the drawings and models, resulting in frequent errors during the construction process, seriously affecting the construction progress, and increasing the construction cost.

[0005] Therefore, how to effectively improve the reliability of drawing-model linkage, improve the efficiency and accuracy of construction workers in obtaining building information, and thus improve the construction efficiency has become an urgent problem to be solved in this field.

[0034] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below with reference to specific illustrations.

[0035] Refer to Figure 1 , which shows an example of the integrated drawing and model interaction system provided by the present invention.

[0036] As can be seen from the figure, the interaction system of this example mainly includes a semantic association and dynamic indexing module 100, a holographic projection and gesture interaction module 200, a conflict detection and optimization decision-making module 300, and a distributed collaborative management module 400.

[0037] The semantic association and dynamic indexing module 100 can perform semantic association on the drawings and models, synchronously locate the index areas and index components corresponding to the natural language instructions in the drawings and models, and perform holographic projection of the drawings and models through the holographic projection and gesture interaction module 200, so as to improve the efficiency and accuracy of obtaining information, reduce the time cost of switching between the drawings and models, and improve the construction efficiency.

[0038] Furthermore, the conflict detection and optimization decision-making module 300 performs comparative analysis on the drawings and models, can detect collision conflicts, reduce construction errors of the drawings and models. At the same time, the distributed collaborative management module 400 can synchronously store and update the change records and communication information of the drawings and models, can ensure the accuracy of the obtained information, and thus improve the reliability of the drawing and model interaction.

[0039] Among them, the semantic association and dynamic indexing module 100 is configured to establish semantic association between the drawings and models, generate dynamic indexing based on natural language, and locate the index areas and index components corresponding to the natural language instructions in the drawings and models, so as to quickly obtain the information required by the natural language instructions.

[0040] Combined with Figure 2Specifically, the semantic association and dynamic indexing module 100 extracts the text annotations and dimension information of the drawings and the component attribute data of the model, and performs semantic analysis on the text annotations, dimension information and component attribute data through natural language processing or machine learning, thereby establishing a deep semantic association between the drawings and the models and generating a dynamic index.

[0041] As an example, the semantic association and dynamic indexing module 100 uses OCR technology to recognize text in the drawing, converts the image data of the drawing into text data to extract the text annotations. Further, the semantic association and dynamic indexing module 100 parses the text data to separate the dimension information, thereby extracting the text annotations and dimension information of the drawing.

[0042] Furthermore, the semantic association and dynamic indexing module 100 uses a model parsing tool, such as Autodesk Revit, to read the data structure of the model to obtain component attribute data. The component attribute data includes component name, type (such as beam, plate, column, etc.), size specifications (length, width, height), material, spatial position coordinates, connection relationship (connection method with other components), etc., so as to accurately describe the component characteristics.

[0043] The semantic association and dynamic indexing module 100 extracts the text annotation and dimension information of the drawings and the component attribute data of the model and stores them in the form of structured data to facilitate subsequent semantic analysis and processing.

[0044] In order to establish deep semantic associations between drawings and models, the semantic association and dynamic indexing module 100 uses lexical and syntactic analysis of natural language processing technology to extract keywords and grammatical structures of natural language instructions, and calculates the semantic similarity between keywords and text annotations, dimension information and component attribute data, thereby establishing semantic associations between drawings and models, and matching associations to form semantically associated data pairs, for example, "distribution box-electrical equipment components", "four-layer-spatial position association" and other semantically associated data pairs.

[0045] In this way, the semantic association and dynamic indexing module 100 performs semantic analysis on the drawings and models, and establishes deep semantic associations between the drawings and models, so that the semantic association and dynamic indexing module 100 can understand natural language instructions, quickly locate information corresponding to the natural language instructions, and improve the accuracy and efficiency of information acquisition.

[0046] Furthermore, based on the semantic association results of drawings and models, the semantic association and dynamic indexing module 100 assigns a unique index identifier to each semantic association pair, binds the index identifier to the corresponding drawing area and model component location information to obtain and store the index database, thereby generating a dynamic index.

[0047] For example, the semantic association and dynamic indexing module 100 assigns a unique index identifier to the semantic association of "distribution box in the four - layer electrical floor plan", and associates the area where the corresponding distribution box is located in the drawing and the position of the corresponding distribution box component in the model, so as to facilitate rapid indexing.

[0048] In this way, the semantic association and dynamic indexing module 100 can perform dynamic indexing on the input natural - language instructions, and synchronously locate the index area and index components corresponding to the natural - language instructions in the drawing and the model.

[0049] Specifically, the semantic association and dynamic indexing module 100 first performs language parsing on the natural - language instructions to extract the keywords in the natural - language instructions, and semantically associates the keywords with the text annotations, dimension information of the drawing, and component attribute data of the model, and then performs dynamic indexing to locate the corresponding index area and index components.

[0050] As an example, the natural - language instruction input by the construction worker is "View the pipeline routing near the distribution box in the four - layer electrical floor plan". The semantic association and dynamic indexing module 100 first performs language parsing, extracts keywords such as "four - layer", "electrical floor plan", "distribution box", and "pipeline routing", and semantically associates the keywords with the corresponding text annotations, dimension information, and component attribute data.

[0051] Furthermore, in the semantic - association stage, the semantic association and dynamic indexing module 100 calculates the semantic similarity between "four - layer" and the floor annotation of the drawing and the floor attribute of the model to determine the floor range, and matches and associates "electrical floor plan" with the drawing - type annotation. At the same time, it matches and associates "distribution box" and "pipeline routing" with the model - component name and attributes to obtain the corresponding semantic - association data pairs.

[0052] Then, the semantic association and dynamic indexing module 100 performs dynamic indexing according to the semantic - association result, searches for the index identifier of the corresponding semantic - association data pair in the index database, so as to obtain the index area as "distribution box in the four - layer electrical floor plan" and the index component as "pipeline routing", and performs synchronous positioning in the drawing and the model to quickly obtain the information required by the construction worker.

[0053] The thus - formed semantic association and dynamic indexing module 100 generates dynamic indexing by establishing semantic associations between the drawing and the model, locates the information required by the natural - language instructions, so as to improve the accuracy and efficiency of information acquisition.

[0054] Combined with Figure 3, in order to quickly and intuitively display the acquired information, without switching between drawings and models, and improve construction efficiency, the holographic projection and gesture interaction module 200 is configured to synchronously perform holographic projection on the drawings and models of the corresponding index area, and at the same time highlight the index components, so that construction personnel can view the required information in the drawings and models synchronously.

[0055] Specifically, the holographic projection and gesture interaction module 200 can be configured on the mobile device side, which is convenient for synchronously viewing drawings and models at the construction site and can quickly check the construction situation. The holographic projection and gesture interaction module 200 is wirelessly connected to the semantic association and dynamic indexing module 100, so that the holographic projection and gesture interaction module 200 can receive the index area and index components located by the semantic association and dynamic indexing module 100 in real time, and emit the holographic projection of the corresponding drawings and models, and at the same time highlight the index components in the drawings and models to intuitively display the corresponding information.

[0056] As an example, the mobile device side cooperates with a holographic projection device, such as an existing portable holographic projector. The holographic projection device is arranged at the construction site. After the holographic projection and gesture interaction module 200 receives the index area and index components, it wirelessly transmits the drawings and models containing the index area to the holographic projection device, and intuitively displays the holographic images of the corresponding drawings and models in the holographic projection device, and at the same time highlights the corresponding index components in the drawings and models.

[0057] Furthermore, the holographic projection and gesture interaction module 200 can also control the display state of the holographic images of the drawings and models through gesture actions, and respectively control the selection, view switching, rotation and scaling of the components in the drawings and models through gesture actions to view the required information in detail.

[0058] Combined with Figure 3 , specifically, the camera of the mobile device or the holographic projection device captures gesture action images and transmits the gesture action images to the holographic projection and gesture interaction module 200 in real time, so that the holographic projection and gesture interaction module 200 extracts features from the gesture action images through an image recognition algorithm. For example, it extracts gesture shape and gesture movement trajectory features.

[0059] Furthermore, the holographic projection and gesture interaction module 200 compares and analyzes the extracted features with a preset gesture action template, determines the gesture action type, matches the gesture action with the preset gesture action template, and thus triggers the corresponding control instruction to control the display state of the holographic image.

[0060] As an example, when the gesture action is a fist, the holographic projection and gesture interaction module 200 extracts the fist shape feature, matches it with the preset fist template, and thus triggers the control instruction for selecting components to select the corresponding index components.

[0061] Correspondingly, the gesture action is waving, which can trigger a rotation control instruction to rotate the drawing and the model and switch the holographic image view. The gesture action is two-finger zooming, which can trigger a zoom control instruction to correspondingly adjust the sizes of the model drawing and the model.

[0062] The following is an example to illustrate the specific application of the holographic projection and gesture interaction module 200. For example, the holographic projection and gesture interaction module 200 performs holographic projection on the drawings and models of complex electromechanical systems. Construction workers can select specific index components through a fist gesture action, and then use the two-finger zoom gesture to enlarge the index component part in the drawings and models to view the connection details of the internal pipelines.

[0063] The holographic projection and gesture interaction module 200 thus constituted can intuitively display the information required by construction workers, further improve the efficiency and accuracy of information acquisition, provide an immersive and intuitive drawing-model interaction experience for users, enable construction workers to more clearly understand the building structure and construction requirements, and reduce construction errors.

[0064] To improve the reliability of drawing-model interaction, this interaction system further includes a conflict detection and optimization decision-making module 300. The conflict detection and optimization decision-making module 300 is configured to perform comparative analysis on the drawings and models, detect pipeline collisions and component conflicts, and at the same time generate corresponding optimization schemes based on preset construction goals such as the lowest cost and the shortest construction period, thereby improving construction efficiency and quality.

[0065] Combined with Figure 4 , specifically, the conflict detection and optimization decision-making module 300 extracts the pipeline and component information in the drawings and models as corresponding spatial features, such as the coordinates and dimensions of pipelines and components, and uses spatial analysis algorithms to calculate the spatial position relationships of each pipeline and component respectively, and compares and judges whether the spatial position relationships of each pipeline and component overlap. If there is an overlap, it is determined that there is a collision conflict between the pipeline and the component.

[0066] Furthermore, when the conflict detection and optimization decision-making module 300 detects pipeline collisions and component conflicts, it will generate multiple optimization schemes based on construction conditions such as construction progress and construction cost, and respectively evaluate the impact of each optimization scheme on the preset construction goals. At the same time, it will sort the multiple optimization schemes according to the degree of impact, so as to effectively control the construction quality according to the drawing-model interaction and improve the reliability of this interaction system.

[0067] Specifically, the conflict detection and optimization decision-making module 300 collects construction progress plan and cost budget data to obtain construction conditions, and then generates optimization schemes such as material replacement, construction sequence adjustment, and increase of manpower and equipment according to the pipeline collision and component conflict situations, combined with construction cost and construction progress, to obtain multiple optimization schemes.

[0068] Next, according to the preset construction objectives, the conflict detection and optimization decision-making module 300 calculates the changes caused by each optimization plan to the construction progress and construction cost respectively, obtains the cost index value and the construction period index value corresponding to each optimization plan, so as to obtain the influence of each optimization plan on the preset construction objectives.

[0069] Furthermore, the conflict detection and optimization decision-making module 300 uses evaluation algorithms, such as the analytic hierarchy process, to determine the cost weight and the construction period weight corresponding to the preset construction objectives respectively, assigns weight coefficients to the cost index value and the construction period index value of each optimization plan, comprehensively calculates the scores of each optimization plan, and sorts the optimization plans according to the final scores, so as to determine the optimal plan.

[0070] As an example, the conflict detection and optimization decision-making module 300 compares and analyzes the drawings and models, extracts the pipeline coordinates and pipe diameter data, calculates that two pipelines collide through the spatial analysis algorithm. At this time, the conflict detection and optimization decision-making module 300 generates optimization plans for changing the installation order and adjusting the pipeline alignment based on the construction progress and construction cost respectively, and evaluates the construction progress delay time and cost changes caused by the optimization plan of changing the installation order, as well as the increase in materials and construction costs caused by the optimization plan of adjusting the pipeline alignment.

[0071] Furthermore, the conflict detection and optimization decision-making module 300 sets the cost weight and the construction period weight according to the preset construction objectives, calculates the comprehensive scores of the optimization plans for changing the installation order and adjusting the pipeline alignment respectively, and sorts the optimization plans according to the scores.

[0072] The conflict detection and optimization decision-making module 300 thus constituted can achieve conflict detection through drawing-model interaction, generate optimization decision-making plans by combining multiple factors, provide a scientific basis for construction decisions, effectively avoid construction errors, and reduce costs.

[0073] Furthermore, this interaction system further includes a distributed collaborative management module 400, which is configured to be able to store and update the change records and communication information of the drawings and models by all parties of the project in real time, so as to ensure the accuracy and reliability of the drawing-model interaction.

[0074] Combined Figure 5 , specifically, the distributed collaborative management module 400 can be composed of an existing blockchain management system. Based on the blockchain technology, there are management nodes corresponding to all parties of the project, such as the construction unit, the construction unit, and the design unit, etc., so that all parties of the project can communicate with this interaction system through the corresponding management nodes, and make changes and communicate to the drawings and models, ensuring the reliability of the drawing-model interaction.

[0075] If either party makes changes to the drawings and models, the distributed collaborative management module 400 will store and update the corresponding change records in real time, and store and update the change records to all management nodes, so that all parties involved in the project can obtain the latest drawings and models as well as the corresponding change records, and can provide feedback and communicate about the changes through the distributed collaborative management module 400, so that the distributed collaborative management module 400 synchronously stores and updates the communication information to all management nodes, thus realizing data sharing and collaborative management among all parties involved in the project.

[0076] As an example, after the design unit changes the drawings, the distributed collaborative management module 400 stores and updates the change records to all management nodes, and the other parties can view the updated drawings and change records through the distributed collaborative management module 400.

[0077] As an example, when the construction unit finds a deviation between the actual construction and the model during the installation of pipelines, the problem and on-site photos are uploaded to the system through the distributed collaborative management module 400, and the distributed collaborative management module 400 stores and updates the communication information to all management nodes in real time, so that the design unit and the construction unit can view the communication information and jointly discuss solutions.

[0078] The distributed collaborative management module 400 thus constituted, based on the characteristics of the blockchain, can ensure the accuracy of the drawings and models, store all change records and communication information to ensure information traceability, and at the same time ensure data consistency and immutability, effectively improving the collaborative management efficiency of all parties involved in the project and enhancing the reliability of drawing-model interaction.

[0079] In specific applications, the semantic association and dynamic indexing module 100, the conflict detection and optimization decision-making module 300, and the distributed collaborative management module 400 are configured on the PC / web side to facilitate the interaction and analysis of drawings and models. The holographic projection and gesture interaction module 200 is configured on the mobile device side to facilitate the intuitive display of drawings and models through the holographic projection and gesture interaction module 200 at the construction site.

[0084] Furthermore, the conflict detection and optimization decision-making module 300 synchronously detects pipeline collisions and component conflicts in the drawings and models and generates corresponding optimization solutions to improve the construction efficiency and quality.
