BIM (Building Information Modeling) technology is a digital design and construction method, and BIM technology can integrate all information of a building or engineering project into one three-dimensional model. The technology can help designers, architects, engineers and constructors share and cooperate in different stages of the project, thereby improving the efficiency and quality of the project, reducing mistakes and repeated work, and reducing cost and risk. BIM technology has been widely used in the fields of construction, civil engineering, hydraulic engineering, etc.
In hydraulic engineering, the application of BIM technology can help designers and engineers better understand the complexity and details of projects, and thus better plan and design the project. The BIM technology can display various parts of hydraulic engineering, such as reservoirs, sluice, diversion channels, water pumping stations and the like, in a three-dimensional model form, so that the structure and the function of the engineering can be more intuitively known. BIM techniques can help designers and engineers to better coordinate. In conventional design and construction processes, communication between designers and engineers is typically through mail, telephone or face-to-face meetings. This approach can easily lead to information that is not timely, accurate, or missing. While BIM technology can integrate various stages of design and construction into one platform, allowing designers and engineers to share and collaborate, thereby reducing mistakes and repetitive tasks. BIM technology can also help designers and engineers better manage projects. In conventional design and construction processes, the various stages of design and construction are typically performed separately, with each stage having respective documents and data. This approach can easily lead to lost or inconsistent information, while BIM techniques can integrate the various stages of design and construction into one platform, allowing designers and engineers to better manage and share information for the project, thereby improving the efficiency and quality of the project. In the construction process of hydraulic engineering, BIM technology can also help engineers to control cost and risk better, and the progress, quality and cost of engineering can be monitored and controlled in real time in the construction process, so that problems can be found and solved in time, and cost and risk are reduced.
The problem of solving design and construction segmentation by using the BIM technology is one of the most efficient modes at present, but this also results in the continuous upgrading of contradictions between project participants in terms of software selection and model pairing, for example: BIM modeling software cannot be unified, a design model cannot be applied by construction, and the like, and the contradictions gradually become important barriers throughout the whole life cycle of BIM projects. How to open the data butt joint between BIM modeling platforms, reduce repeated modeling work in each stage, expand the application value of BIM technology, and the integration of power-assisted design construction is one of the important problems of industry attention. Accordingly, an optimized BIM-based hydraulic engineering information management system is desired.
Fig. 1 shows a block diagram schematic of a BIM-based hydraulic engineering information management system according to an embodiment of the present invention. As shown in fig. 1, a BIM-based hydraulic engineering information management system 100 according to an embodiment of the present invention includes: the BIM model construction module 110 is used for constructing and designing a BIM model based on hydraulic engineering projects; a construction site BIM model building module 120 for building a construction site BIM model based on a construction site of hydraulic engineering; the entity component processing module 130 is configured to split the entity components designed with the BIM model to obtain a plurality of entity components, build a model component classification table corresponding to the entity components, and assign coding attributes to the entity components; a design construction management module 140, configured to perform information management on the design BIM model and the construction site BIM model to obtain a design construction BIM model; and a dynamic collision checking module 150, configured to integrate the design construction BIM model after the dynamic collision checking into a design construction integrated project management platform for application after the dynamic collision checking is performed on the design construction BIM model.

In a specific example of the present invention, a construction site BIM model building module is configured to build a construction site BIM model based on a construction site of hydraulic engineering, and the specific implementation procedure includes: collecting relevant data of construction sites, including a site plan view, a topographic map, an earth volume and the like; importing the collected data into BIM software to perform three-dimensional modeling, wherein the three-dimensional modeling comprises site topography, construction equipment, construction materials and the like; optimizing and adjusting the modeled BIM model to ensure that the BIM model meets construction requirements and safety specifications; and outputting the construction site BIM model into a visual three-dimensional model so as to facilitate cooperation and management of construction personnel.
In a specific example of the present invention, the entity component processing module is configured to split entity components for designing a BIM model to obtain a plurality of entity components, and build a model component classification table corresponding to each entity component, and assign coding attributes to each entity component, where the specific implementation flow includes: analyzing and splitting the designed BIM model, and splitting the BIM model into a plurality of entity components; classifying each entity component and establishing a corresponding model component classification table; and, assigning coding attributes to each entity member for subsequent information management and querying.
In a specific example of the present invention, the design and construction management module is configured to perform information management on a design BIM model and a construction site BIM model to obtain the design and construction BIM model, and the specific implementation process includes: integrating the design BIM model and the construction site BIM model to obtain the design construction BIM model; information management is carried out on the design construction BIM model, wherein the information management comprises construction progress, material management, construction quality and the like; and realizing the collaboration and management of designers, engineers and constructors by designing the construction BIM model.
In a specific example of the present invention, after the dynamic collision checking module is used for performing dynamic collision checking on the design construction BIM model, the design construction BIM model after the dynamic collision checking is fused into the design construction integrated project management platform for application, and the specific implementation process includes: performing dynamic collision checking on the designed construction BIM model to check whether collision problems exist among the components; analyzing and processing the inspection result to solve the collision problem; and integrating the design and construction BIM model after the dynamic collision inspection into a design and construction integrated project management platform, so as to realize information sharing and collaboration and improve project efficiency and quality.
Accordingly, in consideration of the fact that in the actual BIM-based hydraulic engineering information management process, it is particularly important to conduct information management on the design BIM model and the construction site BIM model to obtain the design construction BIM model, the method is a key for achieving project management of design construction integration and improving quality and efficiency of hydraulic engineering projects. Based on the above, in the technical scheme of the invention, the three-dimensional characteristic information of the design BIM model and the construction site BIM model is expected to be fully captured and described by utilizing an artificial intelligence technology based on deep learning, so that the accuracy of the design construction BIM model generation is improved, and the efficiency of design construction integrated management and the quality of hydraulic engineering projects are optimized.
Accordingly, in one possible implementation, as shown in fig. 2, the design construction management module 140 includes: a model acquisition unit 141 for acquiring the design BIM model and the construction site BIM model; a model feature extraction unit 142, configured to perform feature extraction on the design BIM model and the construction site BIM model to obtain a design BIM model feature map and a construction site BIM model feature map; a model feature fusion unit 143, configured to generate a fusion model feature map based on the design BIM model feature map and the construction site BIM model feature map; and a design construction BIM model generating unit 144 configured to generate the design construction BIM model based on the fusion model feature map.
Accordingly, in one possible implementation manner, as shown in fig. 3, the model feature extraction unit 142 includes: a design BIM model feature capture subunit 1421 for extracting the design BIM model feature map from the design BIM model based on a design model feature extractor of a first deep neural network model; and a construction site BIM model feature capture subunit 1422 for extracting the construction site BIM model feature map from the construction site BIM model based on a construction site model feature extractor of the second deep neural network model. It should be appreciated that in a building information system, the design BIM model typically contains complex structures and a large number of elements, and in order to efficiently and accurately extract feature information in the design BIM model, a design model feature extractor based on a three-dimensional convolutional neural network model is further employed to process the design BIM model. It should be noted that, here, the three-dimensional convolutional neural network model can perform three-dimensional feature capture of the design BIM model through a three-dimensional convolutional kernel, so that useful three-dimensional feature information, such as features of structural layout, door and window positions, pipeline trend and the like, is effectively extracted from the design BIM model, and a design BIM model feature map is obtained. Likewise, in hydraulic engineering, the construction site BIM model generally includes a large number of complex three-dimensional structures such as buildings, roads, bridges, floodgates, and the like, and the number and complexity of these structures pose a great challenge to information management of hydraulic engineering. Therefore, in the technical scheme of the invention, the construction site BIM model is passed through a construction site model feature extractor based on a three-dimensional convolutional neural network model to obtain a construction site BIM model feature map. It should be appreciated that by using the three-dimensional convolutional neural network model to perform feature extraction on the construction site BIM model, important three-dimensional feature information in the construction site BIM model can be automatically identified and extracted to significantly improve modeling accuracy. Moreover, the feature extractor based on the three-dimensional convolutional neural network can enable the construction site BIM model to have a visual effect, so that information such as design and layout of the model can be better understood, and efficiency of hydraulic engineering information management is improved.
Accordingly, in one possible implementation, the first and second deep neural network models are both three-dimensional convolutional neural network models. More specifically, the design BIM model feature capture subunit 1421 is configured to: and respectively performing three-dimensional convolution processing, mean pooling processing and nonlinear activation processing based on three-dimensional convolution kernels on input data in forward transfer of layers by the layers of the design model feature extractor based on the three-dimensional convolution neural network model so that the output of the last layer of the design model feature extractor based on the three-dimensional convolution neural network model is the design BIM model feature map, wherein the input of the first layer of the design model feature extractor based on the three-dimensional convolution neural network model is the design BIM model. More specifically, the construction site BIM model feature capture subunit 1422 is configured to: and respectively performing three-dimensional convolution processing, mean pooling processing and nonlinear activation processing on input data in forward transmission of layers by using each layer of the construction site model feature extractor based on the three-dimensional convolution neural network model so that the output of the last layer of the construction site model feature extractor based on the three-dimensional convolution neural network model is the construction site BIM model feature map, wherein the input of the first layer of the construction site model feature extractor based on the three-dimensional convolution neural network model is the construction site BIM model.
It should be noted that the three-dimensional convolutional neural network model (3D CNN) is a neural network model based on deep learning, and is used for processing three-dimensional data, and the three-dimensional convolutional neural network model is similar to a general convolutional neural network model (CNN), but can process three-dimensional data, such as video, three-dimensional image, volume data, and the like. The three-dimensional convolutional neural network model comprises basic components such as a convolutional layer, a pooling layer and a full-connection layer, wherein the convolutional layer is a core component, and characteristic information of data can be extracted through a convolutional kernel. In BIM technology, a three-dimensional convolutional neural network model can be used to extract useful three-dimensional feature information, such as features of structural layout, door and window positions, pipeline trends, and the like, from the design BIM model and the construction site BIM model. By using the three-dimensional convolutional neural network model, important three-dimensional characteristic information in the BIM model can be automatically identified and extracted, so that modeling accuracy is remarkably improved. Meanwhile, the feature extractor based on the three-dimensional convolutional neural network model can enable the BIM model to have a visual effect, so that information such as design and layout of the model can be better understood, and efficiency of hydraulic engineering information management is improved.
It should be appreciated that convolutional, pooling, and fully-connected layers are neural network layers commonly used in deep learning. The convolution layer (Convolutional Layer) is one of core layers of the convolution neural network, and is mainly used for extracting features in images or other types of data, and the convolution layer performs convolution operation by sliding a convolution kernel (filter) on input data so as to extract feature information in the input data, wherein the convolution layer generally comprises a plurality of convolution kernels, and each convolution kernel can extract different feature information; pooling Layer (Pooling Layer) is an operation for reducing the size of the feature map, and is usually performed by downsampling the feature map output by the convolution Layer immediately after the Pooling Layer, so as to reduce the size of the feature map, where the Pooling Layer has different Pooling modes, such as maximum Pooling, average Pooling, and the like, and the maximum Pooling is the most commonly used one; the fully connected layer (Fully Connected Layer) is one of the most basic layers in the neural network, and has the main functions of expanding the output characteristic diagrams of the previous convolution layer and the pooling layer into one-dimensional vectors and inputting the one-dimensional vectors into the fully connected layer for classification, regression and other tasks. The fully connected layer typically includes a plurality of neurons, each connected to all neurons of the previous layer. The convolution layer and the pooling layer are mainly used for feature extraction, and the full-connection layer is used for tasks such as classification, regression and the like. In convolutional neural networks, convolutional layers, pooling layers and fully-connected layers are typically used alternately, which constitutes the basic framework of the deep learning model.
Further, it should be appreciated that both the design BIM model and the construction site BIM model contain a large amount of three-dimensional structural information, but they reflect this information from different levels. The design BIM model generally contains the original design data of the building, and the construction site BIM model is more focused on the visualization effect of the actual construction condition. In order to enable the generated design construction BIM model to have high-precision design information and good visual effect, after the three-dimensional characteristic information of the design BIM model and the three-dimensional characteristic information of the construction site BIM model are obtained, the design BIM model characteristic diagram and the construction site BIM model characteristic diagram are further fused to obtain a fusion model characteristic diagram. Therefore, a more comprehensive and accurate model characteristic diagram can be obtained, key characteristic information of two stages of design and construction is contained, and the generation accuracy of a BIM model for subsequent design and construction and the efficiency of integrated management of the design and construction are improved.
Particularly, in the technical scheme of the invention, the design BIM model feature map and the construction site BIM model feature map are respectively obtained by extracting three-dimensional features of the design BIM model and the construction site BIM model through a feature extractor based on a three-dimensional convolutional neural network model, and the design BIM model feature map and the construction site BIM model feature map are respectively represented by taking a three-dimensional convolutional kernel of the three-dimensional convolutional neural network model as an extraction unit of local associated features, so that model local semantic association representation under the local association scale of the three-dimensional convolutional kernel is also embodied. Accordingly, when the design BIM model feature map and the construction site BIM model feature map are fused to obtain the fusion model feature map, fusion needs to be performed based on the associated feature scale representation of the three-dimensional convolution kernel for three-dimensional local associated feature extraction. Based on the above, the invention carries out global context space association enrichment fusion on the design BIM model feature map and the construction site BIM model feature map to obtain the fusion model feature map.
Accordingly, in one possible implementation manner, the model feature fusion unit 143 is configured to: carrying out global context space association enrichment fusion on the design BIM model feature map and the construction site BIM model feature map by using the following optimization formula to obtain a fusion model feature map; wherein, the optimization formula is:
wherein ,andthe design BIM model feature map and the construction site BIM model feature map are respectively the firstThe number of feature matrices is chosen such that,is the first of the fusion model feature mapThe number of feature matrices is chosen such that,andrespectively matrix multiplication and matrix addition,representing the transposed matrix of the matrix.
Here, in order to gather context spatial correlation semantics between local spatial semantics of a correlation distribution between the design BIM model feature map and the construction site BIM model feature map, the global context spatial correlation enrichment fusion enriches a spatial semantic fusion expression at a frame level of a feature matrix under (enhancement) global perception field by focusing on explicit context correlation at a spatial frame level represented by a feature matrix of the feature map, thereby implementing assimilation (assimilation) fusion of spatial sharing context semantics of a cross-channel of the design BIM model feature map and the construction site BIM model feature map, so as to better fuse the design BIM model feature map and the construction site BIM model feature map, thereby improving a feature fusion expression effect of the fusion model feature map, and also improving generation quality of the fusion model feature map by an AIGC-based design construction BIM model generator.
