Description

Technical Field

[0001] The present invention relates to the technical field of engineering project management, and in particular to an engineering digital management platform based on a BIM model and a management method thereof. Background Art

[0002] As the scale of modern engineering projects continues to expand, the complexity of engineering project management has also increased significantly. The traditional engineering management model mainly relies on two-dimensional drawings, paper documents and manual collaboration, which leads to problems such as untimely information transmission, inconsistent data, and poor communication. This management method cannot meet the current needs of efficient, accurate and collaborative management of engineering projects.

[0003] To solve the above problems, BIM technology has been gradually introduced into engineering project management. BIM technology integrates various data such as building geometry information, material information, construction process, etc. in the form of three-dimensional digital models, providing strong support for project design, construction and operation. However, existing BIM applications are mainly concentrated in the design and construction stages, and support for document management, on-site construction guidance, emergency response, etc. is still not perfect.

[0004] The existing engineering management system has the following deficiencies when combined with BIM technology:

[0005] Document management is not smart enough: Existing systems usually process and manage project documents manually, lack automated information extraction and analysis capabilities, and cannot efficiently and intelligently associate key information with BIM models.

[0006] Insufficient virtual construction guidance capabilities: Although existing systems can use BIM models for three-dimensional visualization, their application in immersive construction scene simulation and AR on-site guidance is not mature enough, resulting in poor virtual drills and increased risks of errors and delays in actual construction.

[0007] Untimely emergency response: Traditional emergency response relies on post-event analysis and manual decision-making, which makes it difficult to respond to emergencies in a timely manner and unable to fully utilize the data in the BIM model for real-time risk assessment and emergency plan generation. Summary of the invention

[0067] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0068] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0069] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0070] Reference Figure 1-Figure 3 , is an embodiment of the present invention, and provides a BIM model-based engineering digital management platform and a management method thereof, the method comprising the following steps:

[0071] Step 1: Build a BIM model for the project and import project-related documents, including design drawings, construction specifications, and material lists.

[0072] Build an intelligent archive management strategy, perform semantic analysis on imported project documents, and automatically extract key information including construction specifications, material requirements, and safety standards, and bind this information to related components in the BIM model. For example, the installation instructions for a structural component can be automatically associated with the specific component nodes in the BIM model.

[0073] Specifically, the intelligent archive management strategy includes the following steps:

[0074] S11: Document D is analyzed using a deep learning model i Perform semantic analysis to extract key information including construction specifications, material safety, and safety standards, and form an information set S(D i );

[0075] S12: Associate and bind the extracted relationship information set with the specific components in the BIM model and express it as a mapping function T(S(D i )); the mapping function T(S(D i )) is calculated as:

[0076]

[0077] Where C is the total number of components in the BIM model, γ C is the information weight associated with the component, Sim(S(D i ),M C ) is the similarity between the extracted information and the components.

[0078] And normalize it, denoted as Φ(T(S(D i )));

[0079] The normalization function here, the normalization function Φ(x), ensures that the key information between different documents is consistent and comparable. This function can be defined based on the minimum-maximum normalization;

[0080] Right now

[0081] S13: Evaluate the processing efficiency of the imported documents, that is, the overall efficiency of processing the kth group within time t is expressed as ψ(k,t);

[0082] The calculation formula of the overall efficiency ψ(k,t) is:

[0083]

[0084] Among them, Q(k) is the processing quality of the k-th group of documents, that is, the accuracy of the extracted information, P(k) is the processing volume of the k-th group of documents, that is, the number of document pages or the amount of information processed, α and β are coefficients for adjusting the weights of quality and processing volume, and δ is the time decay coefficient.

[0085] S14: Calculate and evaluate the semantic distance between documents to obtain a distance E;

[0086]

[0087] S5: Finally, all document processing and binding processes within the entire time period T are cumulatively calculated, and the total efficiency M of the association between the entire project document and the BIM model is finally obtained; the larger the M value, the more efficient the binding between the document information and the BIM model and the closer the association; conversely, a smaller value indicates a lower binding efficiency or a poorer association.

[0088]

[0089] Among them, exp(-λ·t) represents the modeling time decay effect, that is, the efficiency of processing documents decreases over time.

[0090] Step 2: Based on the BIM model that has undergone semantic analysis and associated document information, use virtual reality VR and augmented reality AR technology to build an immersive construction scene; this scene can be used by all parties in the project to conduct virtual drills, check construction steps, and identify potential problems before construction. Through AR equipment, on-site construction personnel can obtain relevant construction instructions and specification requirements in real time to ensure that actual operations meet project standards.

[0091] Step 3: Continue to perform semantic analysis on new documents and automatically update relevant information in the BIM model;

[0092] Step 4: Use sensors to monitor disaster risks during the project implementation phase. Once potential disaster risks are detected, the corresponding emergency response plan is automatically generated based on the design specifications and document information in the BIM model. Managers can also use VR equipment to rehearse emergency plans in advance and optimize personnel scheduling and operating procedures.

[0093] Furthermore, the specific method for generating the corresponding emergency response plan is:

[0094] S41: Assess the severity and likelihood of potential disaster risks and generate corresponding risk scores based on document information;

[0095] The risk score expression is:

[0096]

[0097] Among them, Dj is a set of document information related to the risk, S is a set of design specifications, and w i is the weight of different risk categories, Prob(r i ) and Impact(r i ) are the probability and impact of the ith risk, respectively.

[0098] S42: Calculate the priorities of different emergency response measures, combining risk assessment results and resource allocation;

[0099] The priority of the emergency response is expressed as:

[0100]

[0101] Among them, β k is the resource allocation weight of the kth emergency response measure, and M is the number of all emergency measures.

[0102] S43: Optimize resource allocation to maximize the effectiveness of emergency response;

[0103] The effectiveness maximization of the emergency response can be expressed as:

[0104]

[0105] Among them, ε k is the expected effect of the kth emergency response measure;

[0106] C k (t) is the cost of the kth emergency response measure.

[0107] S44: Comprehensive risk assessment, response priorities and resource optimization to generate the final emergency response plan.

[0108] The final emergency response plan is expressed as;

[0109]

[0110] This value reflects the effectiveness score of a comprehensive emergency response plan. The higher the score, the better the emergency response plan generated by the system is under limited resources.

[0111] Combination Figure 3We can see that, in the context of the present invention, the algorithm optimization effect comparison chart is used to show the difference between the traditional method and the method of the present invention in key performance indicators. Through the visualization effect of the comparison chart, it can be clearly seen that the BIM model management and emergency response generation algorithm introduced by the present invention has significant advantages in efficiency, error reduction, response time, etc. Specifically, the traditional method: the efficiency score is 50, indicating that the traditional method is inefficient in managing BIM models and generating emergency response plans due to the limitations of manual operations and information extraction processes. The method of the present invention: the efficiency score is 80, showing that after applying natural language processing (NLP), deep learning models, and automated semantic analysis and information binding technology, the efficiency of the overall management process has been greatly improved.

[0112] Traditional method: error reduction score is 30. In the traditional method, due to manual operation and inaccurate information processing, a high error rate is prone to occur. The method of the present invention: error reduction score is 10. Thanks to the automated information extraction and association technology, errors caused by manual operation are reduced, making the system more reliable.

[0113] Traditional method: The response time score is 40. The traditional emergency response plan generation process is time-consuming, especially when facing complex disaster scenarios, the manual evaluation and decision-making process slows down the response speed. The method of the present invention: The response time score is 20. The intelligent algorithm introduced in the present invention can realize automation in risk assessment, priority calculation, resource allocation and other steps, thereby greatly shortening the overall response time and quickly generating an efficient emergency response plan.
