DETAILED DESCRIPTION

[0017] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] The following is the relevant background information: The containment of a nuclear power plant is the core part of the structural system, one of the three main systems of a nuclear power plant. It is a prestressed concrete structure with protection and support functions. Its function is to ensure that in the event of a large-scale leak in the reactor, there will be no leakage of radioactive elements, and at the same time it can resist external aggression. All important equipment in a nuclear power plant is located inside the containment, so the containment plays an extremely important role and is also faced with extremely complex loads. Under these loads, the containment will undergo real-time dynamic changes. If the deformation exceeds the safety range, it will directly affect the safe and stable operation of the nuclear power plant. By real-time monitoring of the deformation of the containment, potential safety hazards can be discovered and dealt with in a timely manner to ensure the safety of the nuclear power plant.

[0019] The existing nuclear power plant containment deformation monitoring method is based on Microsoft's WPF (Windows Presentation Foundation) technology. In the actual monitoring process, Blend for Visual Studio is first used to convert the 3D model of the nuclear power plant containment into XAML (Extensible Application Markup Language) code, and these XAML codes are imported into the monitoring project. Then, the 3D model of the nuclear power plant containment is rendered and displayed in real time through the real-time rendering engine of the WPF framework. Finally, by receiving and processing data from the deformation monitoring sensor, the shape and position of the 3D model are continuously updated, thereby realizing real-time and accurate monitoring of the deformation of the nuclear power plant containment.

[0020] Since XAML is mainly designed for layout and elements of user interfaces, rather than for efficient rendering of complex 3D models, some redundant information is inevitably generated in the process of converting the fine 3D model of the nuclear power plant containment into XAML code. This redundant information not only takes up additional system resources, but also increases the burden on the rendering engine, resulting in a slower response speed for the entire monitoring system. Especially when it is necessary to monitor the deformation of the nuclear power plant containment in real time, this decrease in response speed will directly affect the timeliness and accuracy of monitoring, and thus cannot meet the requirements of the nuclear power plant for real-time monitoring.

[0021] Embodiment 1 Reference Figure 1 and Figure 2 , a method for rendering a nuclear power plant containment model provided in an embodiment of the present application includes the following steps: S101: reading a three-dimensional model of a nuclear power plant containment structure, wherein the three-dimensional model includes at least three-dimensional coordinate information of nodes, and the three-dimensional coordinate information of the nodes represents the three-dimensional coordinates of each key point in the containment structure of the nuclear power plant.

[0022] In this embodiment, the three-dimensional model represents the real-time state of the nuclear power plant containment, which is the basis for model rendering. Each key point in the nuclear power plant containment structure represents an important node, connection point, support point or key part on the nuclear power plant containment, and each key point includes at least the top, bottom, edge and points connected to other structures of the nuclear power plant containment; the node three-dimensional coordinate information is collected by scanning tools, and the pre-saved node three-dimensional coordinate information can also be directly retrieved from the database. Specifically, the three-dimensional coordinates of each key point in the nuclear power plant containment structure include but are not limited to Cartesian coordinates; by reading the three-dimensional model of the nuclear power plant containment, the actual position of each key point in the nuclear power plant containment structure in the current state can be obtained.

[0023] Exemplarily, first, according to the file path and file name of the three-dimensional model of the nuclear power plant containment, the specific location of the three-dimensional model on the storage medium is determined; according to the file path, file name, and specific location on the storage medium of the three-dimensional model of the nuclear power plant containment, the three-dimensional model is read, and the three-dimensional model includes at least the three-dimensional information of the nodes representing the three-dimensional coordinates of each key point in the nuclear power plant containment structure.

[0024] For example, Table 1 shows the node three-dimensional information of the three-dimensional coordinates of each key point in the nuclear power plant containment structure. As shown in Table 1, type=C3D8 indicates that the nuclear power plant containment is a three-dimensional 8-node unit, each node corresponds to a node number, and each node number corresponds to a set of Cartesian coordinates.

[0025] Table 1

[0026] S102: Calculate the maximum offset distance and offset information of the three-dimensional model according to the node three-dimensional coordinate information and the node reference coordinates, wherein the maximum offset distance represents the maximum deformation degree of the nuclear power plant containment, the offset information represents the position offset degree of each key point in the nuclear power plant containment, and the node reference coordinates represent the three-dimensional coordinates of each key point in the nuclear power plant containment structure in a non-deformed state.

[0027] In this embodiment, the offset information is calculated by calculating the difference between the three-dimensional coordinates of each node and the node reference coordinates. The offset information characterizes the degree of position offset of each key point in the nuclear power plant containment. The degree of position offset of each key point in the nuclear power plant containment includes at least an offset distance and an offset direction. By comparing the degree of position offset of each key point in the nuclear power plant containment, the maximum offset distance is determined. Specifically, the offset information includes at least an offset distance and an offset direction of each key point in the nuclear power plant containment.

[0028] By calculating the maximum offset distance and offset information, the deformation of the nuclear power plant containment in the current state can be obtained, the rendering strategy can be determined, and the three-dimensional model can be rendered according to the rendering strategy, so that the monitoring personnel can intuitively observe the deformation of the nuclear power plant containment and realize real-time deformation monitoring of the nuclear power plant containment.

[0029] S103: Calculate the color value of each triangular face in the three-dimensional model according to the maximum offset distance and the offset information, where the color value is used to characterize the deformation of the three-dimensional model.

[0030] In this embodiment, the maximum offset distance is used as a reference value to normalize or standardize the offset information, ensuring that all offset information is represented within a unified color value range to avoid misunderstanding or confusion caused by different data ranges. The offset information is used as a direct basis for the color value, and the color value of each triangle face in the three-dimensional model is calculated according to the vertex offset of each triangle face in the three-dimensional model to provide support for subsequent model rendering.

[0031] For example, first, based on the maximum offset distance, the offset information is mapped to a preset color value interval. The color value interval represents the color change from no deformation to maximum deformation, so that the monitoring personnel can intuitively see the deformation degree of the nuclear power plant containment. Then, for each triangular face in the three-dimensional model, the average value of all vertex offsets of each triangular face is calculated, and this average value is mapped to the color value interval to obtain the specific color value of each triangular face. The color value of each triangular face not only reflects the overall deformation degree of the face, but also provides an intuitive visual reference for the monitoring personnel through the changes in color depth.

[0032] For example, in addition to the offset, visual elements other than color values ​​are used to assist in indicating the direction of the offset, helping monitoring personnel to more comprehensively understand the deformation mode and deformation trend of the nuclear power plant containment, thereby improving the accuracy and efficiency of monitoring and providing a strong technical guarantee for the safe operation of the nuclear power plant. Specifically, visual elements other than color values ​​include at least arrows, color gradients and other elements.

[0033] S104: grouping the color values, rendering the groups as batches, and generating a rendering model of the nuclear power plant containment vessel.

[0034] In this embodiment, the color values ​​of all triangular facets in the three-dimensional model are first analyzed and classified, and the triangular facets are divided into several groups to ensure that the color values ​​of the facets in each group are not much different but relatively obvious; then, batch rendering is performed in groups. During the rendering process, all triangular facets in the three-dimensional model are grouped according to the color value and rendered in batches in groups, which can reduce the amount of calculation during rendering, ensure the real-time rendering, and achieve real-time monitoring of the deformation of the nuclear power plant containment.

[0035] Figure 2 A rendering effect diagram of the nuclear power plant containment rendering model in an embodiment of the present application is shown. The gray part in the figure represents the absence of deformation in the response position, and the red part represents the deformation degree of the nuclear power plant containment from small to large from light to dark.

[0036] For example, the code for rendering in batches is as follows: foreach (var f in dic) { var mb = new MeshBuilder(); for (int i = 0; i<f.Value.Count - 2; i += 3) { mb.AddTriangle(pc[f.Value[i]], pc[f.Value[i + 1]], pc[f.Value[i +2]]); } varm3d = new ModelVisual3D() { Content = new GeometryModel3D() { Geometry = mb.ToMesh(true), Material = new DiffuseMaterial(ba[f.Key]) } }; parent.Children.Add(m3d); MainWindow.Instance.MessageListBox.PostMessage($"{nameof(DrawModelDataByObjectAsync)} renders color level {f.Key}, number of triangles {f.Value.Count / 3}"); / / await Task.Delay(1);} } } The embodiment of the present application determines the three-dimensional coordinates of the nodes that characterize the current state of each key point in the containment structure of the nuclear power plant by reading the three-dimensional model of the nuclear power plant containment, and calculates the maximum offset distance and offset information of the three-dimensional model of the nuclear power plant containment according to the three-dimensional coordinates of each key point in the containment structure of the nuclear power plant in the non-deformed state, uses the maximum offset distance as the reference value, normalizes or standardizes the offset information, ensures that all offset information is represented in a unified color value range, calculates the average value of all vertex offsets of each triangular face, and maps this average value to the color value range to obtain the specific color value of each triangular face. All triangular facets of the three-dimensional model are grouped according to the specific color value, and rendered in batches in groups. It solves the problem that the use of XAML code and WPF framework in the prior art will generate redundant information, increase the burden on the rendering engine, and cause the response speed of the entire monitoring system to slow down, and cannot meet the needs of real-time monitoring of the deformation state of the nuclear power plant containment. It realizes the representation of the deformation of the nuclear power plant containment in a unified color value range, avoiding misunderstanding or confusion caused by different data ranges. At the same time, it provides an intuitive visual reference for monitoring personnel through changes in color depth. All triangular faces in the three-dimensional model are grouped according to color values ​​and rendered in batches based on groups. This can reduce the amount of calculation during rendering, ensure the real-time rendering, and achieve real-time monitoring of the deformation of the nuclear power plant containment.

[0037] Reference Figure 3 Before S103: calculating the color value of each triangular face in the three-dimensional model according to the maximum offset distance and the offset information, the following steps are also included: S201: Analyze the model structure of the three-dimensional model, and determine a segmentation algorithm and algorithm parameters corresponding to the segmentation algorithm.

[0038] In this embodiment, the model structure of the three-dimensional model includes at least a geometric structure and a topological relationship, specifically including the number, distribution and connection relationship of the vertices, edges and faces of the three-dimensional model, as well as small feature points and surface changes. The segmentation algorithm includes at least one of curvature-based segmentation, region-based segmentation and graph-theory-based segmentation. Curvature-based segmentation determines the segmentation boundary by analyzing the curvature change of the model surface, region-based segmentation divides the three-dimensional model into different regions according to the color, texture and other attributes of the model surface, and graph-theory-based segmentation determines the segmentation boundary through graph-theory algorithms such as maximum cut and maximum flow. The algorithm parameters include at least a segmentation threshold, number of iterations and a smoothing factor. Selecting a suitable algorithm according to the model structure of the three-dimensional model and setting the corresponding algorithm parameters according to the characteristics and requirements of the selected segmentation algorithm can ensure the best segmentation effect.

[0039] S202: Segment the three-dimensional model into a plurality of triangular facets according to a segmentation algorithm and algorithm parameters.

[0040] In this embodiment, the segmentation algorithm divides the 3D model into multiple regions or sub-models according to preset rules and conditions, and then resamples or triangulates the surface of the 3D model to segment the 3D model into multiple triangular facets. The specific triangulation operation includes greedy projection triangulation and Delaunay triangulation algorithm. The use of greedy projection triangulation and Delaunay triangulation algorithm can ensure that the segmented 3D model has good geometric and topological characteristics.

[0041] Specifically, after the 3D model is segmented into multiple triangular facets, the accuracy and reliability of the segmentation structure are verified by comparing the model structures before and after segmentation and analyzing the rationality of the segmentation boundaries, thereby further ensuring the effective segmentation of the 3D model.

[0042] Reference Figure 4 , S103: Calculating the color value of each triangular face in the three-dimensional model according to the maximum offset distance and the offset information, including the following steps: S301: obtaining standard offset information of each key point in the containment structure of the nuclear power plant according to the maximum offset distance and the offset information, wherein the standard offset information represents the standard offset degree of each key point in the containment structure of the nuclear power plant relative to the node reference coordinate.

[0043] S302: Calculate the rendering color value of each key point in the containment structure of the nuclear power plant according to the standard offset information and the preset mapping value.

[0044] S303: Determine the color value of each triangular face according to the rendering color value of each key point in each triangular face.

[0045] In this embodiment, first, the maximum offset distance is taken as a benchmark, and the offset information is converted into standard offset information to obtain the standard offset degree of each key point in the nuclear power plant containment structure relative to the node reference coordinate, that is, the relative position of each key point in the nuclear power plant containment structure relative to the deformation degree of the entire nuclear power plant containment.

[0046] Next, according to the preset mapping relationship, the standard offset information is mapped to a specific color value range. The color value range can be a continuous color gradient from low offset to high offset, or it can be a change in the depth of a single color system, or it can be a combination of multiple colors. Specifically, a corresponding rendering color value is calculated for each key point in the containment structure of the nuclear power plant using the preset mapping relationship. The rendering color value represents the degree of offset of the corresponding key point and is used to determine the color value of each triangular facet.

[0047] Finally, the color value of each triangular face is determined according to the rendered color value and the preset color value determination method. The preset color value determination method uses the average color value method or the interpolation method. The average color value refers to the average value of the color values ​​of each point in each triangular face. The interpolation method calculates the color value of each triangular face based on the rendered color value and position relationship of each key point of the triangular face.

[0048] Exemplarily, when the three-dimensional model is a spatial hexahedral unit, since each face of the three-dimensional model is composed of quadrilaterals, each face is divided into two triangles for rendering, so that the rendering logic meets the bottom-level rendering logic of the graphics card and the rendering performance is guaranteed. When the maximum offset distance of the spatial hexahedral unit is M, the position offset degree of each key point in the containment of each nuclear power plant in the offset information is divided by M, multiplied by 255, and rounded to obtain the rendering color value of each key point in each triangular face. The color value of all triangular face pieces is obtained by taking the average value of the three vertices of each triangular face piece as the color value.

[0049] The standard offset information is obtained through the maximum offset distance and offset information, and the standard offset information is mapped to a specific color value interval to ensure that the color value is unified in a color value interval to avoid misunderstanding or confusion caused by different data ranges. Taking the average rendering color value of each vertex of the triangular patch as the color value of the triangular patch can clearly reflect the deformation area and deformation degree of the nuclear power plant containment corresponding to each triangular patch, providing strong support for the dynamic monitoring and real-time early warning of the nuclear power plant containment.

[0050] Reference Figure 5 S104: grouping the color values, rendering the groups as batches, and generating a rendering model, including the following steps: S401: grouping color values ​​according to a preset grouping standard to obtain a plurality of color value groups, wherein the plurality of color value groups at least include a gray color value group and a red color value group, and the red color value group includes at least one group of red color values.

[0051] In this embodiment, the preset grouping criteria refer to grouping criteria based on the similarity, range, quantity or other relevant factors of color values. Specifically, grouping is performed based on the brightness, hue or saturation of the color values, or clustering is performed based on the distance of the color values ​​in a preset color space.

[0052] Exemplarily, the gray color value group is used to render locations without deformation, and the red color value group is used to render locations where deformation occurs in the containment of a nuclear power plant. In the process of determining the red color value group, the red color values ​​are first sorted from low to high according to brightness, and then divided into multiple brightness intervals. The red color values ​​in each interval form a group of red color value groups. They can also be grouped according to hue, and color values ​​of similar hues can be grouped together; in the color space, the distance between each red color value and other red color values ​​can also be calculated, and cluster analysis can be performed based on the distance to form multiple groups of red color value groups.

[0053] S402: Create a rendering batch for each color value group.

[0054] In this embodiment, the same rendering batch can be rendered simultaneously. When creating a rendering batch for each color value group, a unique rendering batch identifier can be assigned to each color value group, and relevant rendering parameters can be set. The rendering parameters determine the rendering effect of all triangle faces in the same batch. The rendering parameters include at least material, lighting and texture.

[0055] S403: Perform batch rendering using color values ​​corresponding to the rendering batches to obtain a rendering model.

[0056] In this embodiment, according to the parameters of the rendering batch, the state of the graphics rendering pipeline is set, all the triangles in the batch are traversed, and the triangles in the same batch are rendered using the corresponding color values. By grouping the color values ​​and rendering them in batches, the rendering efficiency can be effectively improved and the resource utilization can be optimized.

[0057] Reference Figure 6 , S101: Reading the three-dimensional model of the nuclear power plant containment, including the following steps: S501: Collect the three-dimensional coordinates of each key point in the containment structure of the nuclear power plant.

[0058] S502: Determine the rotation direction according to preset reference point information, where the preset reference point information represents a specific position of the containment vessel of the nuclear power plant.

[0059] S503: Based on the reference point information and the rotation direction, each key point in the containment structure of the nuclear power plant is numbered to generate numbering information of each key point.

[0060] S504: Generate a standard data file according to the serial number information and the type of nuclear power plant containment.

[0061] S505: Read the standard data file to determine the three-dimensional model of the nuclear power plant containment.

[0062] Specifically, a scanning tool is used to collect the three-dimensional coordinates of each key point in the containment structure of a nuclear power plant. The preset reference point information represents a specific position of the containment of the nuclear power plant, which is used to determine the rotation direction of the model. Based on the reference point information and the rotation direction, each key point in the containment structure of the nuclear power plant is numbered, and a standard data file is generated in combination with the type of the containment of the nuclear power plant. By reading the standard data file, the information in the standard data file is imported into the rendering project, and the three-dimensional model of the containment of the nuclear power plant is constructed according to the three-dimensional coordinates and numbering information of the nodes. The three-dimensional model of the containment of the nuclear power plant not only contains the accurate location information of each key point in the containment structure of all nuclear power plants, but also ensures the integrity and accuracy of the model through numbering rules.

[0063] Exemplarily, the standard data file includes node information and unit information. The unit information includes the type of nuclear power plant containment. When the unit information is C3D8, it indicates that the nuclear power plant containment is a 3D 8-node unit, i.e., a spatial hexahedral unit. The node information includes the numbering information of each key point. Specifically, the numbering rule satisfies the right-hand spiral rule, i.e., the thumb points to the positive direction of the rotation axis, the index finger points to the direction of the first key point starting from the reference point, and the middle finger points to the vertical direction of the plane determined by the two points. When numbering, first take the preset reference point information as the starting point, and number each key point in turn according to the direction of the right-hand spiral. This numbering method not only ensures the uniqueness of the numbering, but also helps to quickly identify and locate each key point.
