DETAILED DESCRIPTION

[0018] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0019] Embodiment 1: This embodiment introduces an efficient modeling method for a process pipeline of a thermal power plant, including: Based on the pre-created pipeline system data, pipeline path data and pipe fitting parameter data, a pipeline model is generated, wherein the pipeline model includes an elbow model and a straight pipe segment model. The specific method is as follows: Based on the pipeline system data, pipeline path data and pipe fitting parameter data, the API of the 3D design platform is called at the intersection of the model lines to create an elbow model; Use the pipe fitting sorting algorithm to number the elbows and fill in their corresponding attributes; Use the elbow model rotation algorithm to rotate the elbow to the correct direction; Based on the pipeline system data, pipeline path data and pipe fitting parameter data, the pipeline creation API of the 3D design platform is called to create a straight pipe section model along the model line.

[0020] The application process of the efficient modeling method for process pipelines of a thermal power plant provided in this embodiment specifically involves the following steps: 1. Pipeline system management, used to manage the data of the planned pipeline system; The pipeline system management includes the pipeline system name, pipeline type name, and pipeline segment name; The name of the pipeline system is derived from the name or number of the pipeline system in the design task, so that the user can distinguish the pipeline system; The pipe type name is a type element set by the 3D design platform for managing pipe models. It is a necessary attribute for establishing a pipe model and mainly includes functional attributes such as pipe layout system configuration, type image, and type annotation. The pipe segment name is an object set by the three-dimensional design platform to manage the geometric parameters of the pipeline model. It is a necessary attribute for establishing the pipeline model, and mainly includes parameters such as the nominal diameter, inner diameter, and outer diameter of the pipe segment.

[0021] 2. Pipeline path data creation, using model line data to describe the path of the pipeline in three-dimensional space; The pipeline path data creation includes a model line endpoint data creation method and a model line sorting and numbering algorithm; The model line endpoint data refers to the spatial coordinate data of the starting point and the end point of each model line after simplifying the entire pipeline into a number of model lines connected end to end in the design environment of the three-dimensional design platform.

[0022] The creation methods of the model line endpoint data include the following three methods: Directly draw the model line instance on the 3D design platform, and then extract the starting and ending coordinates of the model lines one by one; Read local or cloud data table files, which contain the starting and ending coordinates of the model line; The model line models created by other design software are imported into the 3D design platform and converted into model lines, and then the starting and ending point coordinates of the model lines are extracted one by one.

[0023] The model line sorting and numbering algorithm refers to the process of numbering each model line in sequence according to the connection order. Specifically, the user first needs to determine the first model line of the pipe system. The user selects a model line and records its starting point and end point coordinates as P 0. P 1, respectively P 0.P 1 is compared with the coordinates of the endpoints of other model lines in turn to determine the number of intersections between the model line and the endpoints of other model lines. If the number of intersections between the model line and other model lines is not equal to 1, it means that the model line is in the middle of the entire pipe system and cannot be used as the first model line. The user needs to reselect it; if the number of intersections is equal to 1, the model line in the pipe system is recorded as 1, and the model line that intersects with its endpoint is recorded as 2, and so on. The algorithm flow is detailed in the attached manual. Figure 1 .

[0024] 3. Pipe fitting parameter retrieval, which allows users to match the target pipe fitting data according to the design parameters; The pipe fitting parameter retrieval includes the retrieval of target pipe fittings such as straight pipe sections and elbows. The input conditions are the design conditions of the pipeline system. The straight pipe section includes five input conditions, such as nominal diameter, outer diameter, design temperature, design pressure, and material. In addition to the above input conditions, the elbow also has angle parameters as input conditions. The user enters one condition or a combination of multiple conditions, and accesses the pipe fitting grade database applicable to the industry design standards through the program. The Boolean retrieval algorithm is used to match the pipe fittings that are suitable for the design conditions. When the retrieval results are 1 to 3 data, the user confirms one of them as the target data to complete the subsequent work.

[0025] 4. Generate pipeline model: Generate corresponding pipeline model according to the input conditions in the above steps; The pipeline model generation includes elbow model generation, pipe fitting sorting algorithm, elbow model rotation algorithm, and straight pipe segment model generation. Specifically, first, at the intersection of the above-mentioned model lines, the API for creating elbows of the three-dimensional design platform is called to create elbow models in sequence, and then the elbows are numbered using the pipe fitting sorting algorithm and filled into their corresponding attributes. Then, the elbow model rotation algorithm is used to rotate the elbow to the correct direction, and the vector direction of the model line is defined as the starting point to the end point, ensuring that the normal vector of the inlet end face of the elbow is equal to the reverse direction of the vector of the previous model line, and the normal vector of the outlet end face of the elbow is equal to the vector of the next model line. Finally, the pipeline creation API of the three-dimensional design platform is called to create a straight pipe segment model along the model line.

[0026] The pipe fitting sorting algorithm is to number the pipe fittings according to the rules. For the straight pipe section model, its serial number in the entire pipe system is f ( j ) satisfies the expression: f ( j ) = 2* j - 1 ; For the elbow model, its serial number in the entire pipe system is g ( j ) satisfies the expression: g ( j ) = 2* j ; in j It is the model line number, which is a positive integer starting from 1 and increasing.

[0027] The elbow model rotation algorithm is a process of rotating the two end faces of the elbow model to the correct direction in the pipe system one by one, that is, through vector calculation, the three parameters of this process, namely, the rotation axis, rotation angle, and rotation base point, are clarified. Finally, the above parameters are used as input conditions to call the three-dimensional design platform pipe rotation API to rotate the two end faces of the elbow to the correct direction.

[0028] Specifically, the elbow is in the initial state after being created in the project. The normal vector of its inlet end face is E(→)1, the normal vector of its outlet end face is E(→)2, the vector of the previous model line is standardized as L(→)1, the vector of the next model line is standardized as L(→)2, and the base point position coordinates of the elbow are P 0 (coordinate of the intersection of the model line), the target of the rotation of the elbow vector can be expressed as follows: ; For the solution process of the above formula, the Figure 2 , Figure 3 express.

[0029] The straight pipe segment model generation refers to the process of creating a straight pipe segment along the model line path. As mentioned above, the elbow model has been created at the intersection of the model line. When generating the straight pipe segment model, the elbow space should be considered and the straight pipe segment model is generated between the following positions: From the starting point of the first model line to the entry endpoint of the first elbow; From the elbow outlet end point to the next elbow inlet end point; From the outlet endpoint of the last elbow in the piping system to the end point of the last model line.

[0030] The serial numbering rule of the straight pipe section adopts the above-mentioned pipe fitting sorting algorithm, and the parameters of the straight pipe section are selected and called according to the above-mentioned pipe fitting parameter retrieval method.

[0031] This embodiment provides an efficient modeling method for process pipelines in a thermal power plant. A pipeline model is generated through pre-created pipeline system data, pipeline path data, and pipe fitting parameter data. A process pipeline modeling flow and method using points, lines, and bodies is proposed, which further improves the flexibility and efficiency of the modeling work.

[0032] Embodiment 2: This embodiment provides an efficient modeling system for process pipelines in a thermal power plant, comprising: The pipeline system management module is used to manage the proposed pipeline system data, including three management modules: pipeline system name, pipeline type name, and pipeline section name; The pipeline path data creation module uses the model line data to describe the path of the pipeline in three-dimensional space, including the model line endpoint data creation module and the model line sorting number algorithm module; The pipe fitting parameter retrieval module allows users to match the target pipe fitting data according to the design parameters, including the use of Boolean retrieval algorithm to retrieve the straight pipe section and elbow data module; A pipeline model generation module, used to generate a pipeline model based on pre-created pipeline system data, pipeline path data and pipe fitting parameter data, wherein the pipeline model includes an elbow model and a straight pipe section model; Wherein, the pipeline model generation module includes: The elbow model generation module is used to create an elbow model by calling the API of the 3D design platform at the intersection of the model lines based on the pipeline system data, pipeline path data and pipe fitting parameter data; A pipe fitting sorting algorithm module is used to use the pipe fitting sorting algorithm to number the elbows and fill in their corresponding attributes; An elbow model rotation algorithm module is used to rotate the elbow to a correct direction using an elbow model rotation algorithm; The straight pipe section model generation module is used to call the pipeline creation API of the three-dimensional design platform based on the pipeline system data, pipeline path data and pipe fitting parameter data to create a straight pipe section model along the model line.
