However, when creating sprinkler system models, designers must manually create each pipe individually. Furthermore, the installation of pipe accessories and electromechanical equipment also requires manual installation using their own template libraries. This process involves a large amount of repetitive operations, which is time-consuming and labor-intensive, and affects the efficiency of sprinkler system modeling.

[0003] Therefore, it is necessary to develop a sprinkler system modeling method that can quickly create pipelines on a 3DE platform and save time and effort. Summary of the Invention

[0068] Example 1

[0069] like Figure 1As shown, this embodiment uses the sprinkler system modeling method based on the 3DEXPERIENCE platform to implement sprinkler system modeling. The implementation is divided into six steps: Step 1: Building the sprinkler system resource library; Step 2: Building the sprinkler system structure tree; Step 3: Creating the main pipe; Step 4: Creating the branch pipe; Step 5: Creating the sprinkler pipe; and Step 6: Installing the pipe accessories.

[0070] In the above technical solution, the method for implementing step 1 to create a water supply and drainage template library is as follows:

[0071] 1) Log in to the 3DE platform with an administrator account

[0072] 2) Click the New Content command button to create a template library directory object.

[0073] 3) Switch to the water supply and drainage pipeline or water supply and drainage pipe accessory definition app and create a water supply and drainage pipeline or pipe accessory template.

[0074] 4) Add the created template to the corresponding pipeline and pipe accessories chapter in the template library directory.

[0075] 5) Switch to the Data setup app and attach the created template library to the resource set associated with the project space.

[0076] In the above technical solution, the second step is to build a structure tree for creating a sprinkler system, and to create pipeline path points and sprinkler head positioning points. This includes the following steps:

[0077] 1) Log in to the 3DE platform, click the New Content command button, create a product node of type Other AEC Space Structure Elements, and name it "Create Sprinkler System".

[0078] 2) With "Create Sprinkler System" as the root node, create a knowledge engineering specification object under it and name it "Pipeline System EKL". Attach the Action objects containing EKL codes for creating pipeline objects, adding pipeline path points, and changing pipeline references to this node. For the corresponding Action objects, see the attached document. Figure 8 Structure tree of the present invention.

[0079] 3) Insert a 3D shape object under the "Create Sprinkler System" node and name it "Pipeline Path Points and Nozzle Positioning Information" to record the path points and nozzle positioning information of the sprinkler system main pipe in the form of feature points and knowledge engineering parameters.

[0081] 4) Start the developed Create Sprinkler System command, select the sprinkler system node to be created, and click OK to execute the creation of the entire sprinkler system.

[0082] 5) Complete the construction of the sprinkler system tree. See the system tree for details. Figure 8 .

[0083] In the above process, the specific steps for creating pipeline path points and nozzle positioning points are as follows:

[0084] 1) Obtain the corresponding feature container interface (CATIMmiPtrContainer) through the pipeline path point and the nozzle positioning information 3Dshape node.

[0085] 2) Create the interface CATICkeParmFactory based on the container parameters, and create a design table associated with the pipeline path points and nozzle positioning information Excel table. The input parameters in the table are shown in Figure 9 .

[0086] 3) Read the contents of the design table, create a corresponding geometry set under PartFeature based on the main pipe name in the Excel table of pipeline path points, create a geometry set corresponding to the pipe segment based on the pipe segment name under the main pipe geometry set, parse the strings corresponding to the start and end point coordinates of the pipe segment, and obtain the start and end point coordinates.

[0087] 4) According to the coordinates of the starting and ending points of the pipeline, create the feature points corresponding to the starting and ending points under the pipe segment geometry set. The main structure tree is shown in the attached Figure 10 , the main pipe geometry set is the geometry set of each pipe section of the main pipe, and the geometry set of each pipe section is the starting point and end point of the pipe section;

[0088] 5) Based on the nozzle positioning information associated with the design table, create a geometric set named branch pipe number under PartFeature, read the Excel table of nozzle positioning information associated with the design table, and create feature points recording the nozzle position under the corresponding branch pipe number geometric set based on the nozzle positioning information.

[0089] 6) Read the nozzle binding information in EXCEL, create the main pipe and specification string type parameters, use the nozzle positioning feature point as the parameter publishing object, and hang the created parameters under the nozzle positioning feature point node. See the attached branch pipe structure tree. Figure 10 ;

[0090] In the above technical solution, according to Figure 2 To implement step 3 and create a pipeline supervisor, follow these steps:

[0091] 1) Select the "Sprinkler System" node, and recursively traverse the parent nodes of this system node to obtain the root node of the entire tree - "Create Sprinkler System";

[0092] 2) Obtain all child nodes of the first level through the root node, and filter by name to obtain the "Pipeline Path Point and Nozzle Positioning Information" 3D shape node and the "Pipeline System EKL" knowledge engineering specification node;

[0093] 3) Get the part geometry and all main path geometry sets in the 3Dshape node;

[0094] 4) Obtain the pipe diameter specification for creating the pipeline main according to the name of the geometric set;

[0095] 5) Read the coordinates corresponding to the feature points under the geometric set and create corresponding coordinate feature points under the part geometry;

[0096] 6) Obtaining a reference to a pipeline template of corresponding specifications from a template library according to the pipeline specifications obtained in step 4);

[0105] 2) Get the nozzle location point coordinates and the bound main pipe in the branch pipe geometry set;

[0106] 3) Create a geometry set named pipe attachment anchor points under 3Dshape;

[0107] 4) Determine the path points of each branch pipe segment based on the coordinates and number of the nozzle positioning points in the branch pipe geometry set: calculate the distance between the first nozzle positioning point and the end point of each pipe segment in the bound main pipe. The end point with the smallest distance is the starting point of the first pipe segment path of the branch pipe. The first nozzle positioning point is the end point of the first pipe segment path of the branch pipe. The starting point and end point of the second pipe segment path of the branch pipe are the first nozzle positioning point and the second nozzle positioning point respectively. The subsequent pipe segments are deduced in this way. According to the number of nozzle positioning points on the branch pipe, the diameter of the branch pipe is determined according to relevant specifications; according to the starting point of the first pipe segment path, the starting point and end point of the first pipe segment path are determined. Create a corresponding feature point under the pipe accessory positioning point geometry set at the starting point coordinates, obtain the other branch pipe geometry sets that are also bound to the main pipe, calculate the distance between the first nozzle positioning point in the geometry set and the endpoints of each pipe segment bound to the main pipe, and obtain the endpoint with the smallest distance. If there is an endpoint that is the same as the feature point, it means that two branch pipes are connected to the feature point, and the feature point is named a four-way. If not, it means that the feature point is connected to a branch pipe, and the feature point is named a three-way. The bound main pipe and pipe segment information and the pipe segment information of the first pipe segment of the branch pipe are recorded under the feature point.

Obtain the geometric shapes and part geometry corresponding to all path points in the 3Dshape node. Obtain the pipe diameter for creating the pipe main based on the name of the geometric shape. Read the coordinates of the feature points under the geometric shape and create feature points corresponding to the coordinate points under the part geometry. Based on the obtained pipe diameter, traverse the pipe template library to obtain the pipe template with the corresponding diameter. Using the created "Sprinkler System" node as input, CAA calls the Action object created for the pipeline to complete the creation of the pipeline main. Step 4: Create a branch pipe: Traverse the geometric shapes set under the 3D shape to obtain the geometric shape set containing the sprinkler positioning information; obtain the sprinkler positioning points and the bound main pipe within the geometric shape set; create a geometric shape set for the pipe accessory positioning points under the 3D shape; obtain the branch pipe path points based on the sprinkler positioning points and the bound main pipe, and create corresponding feature points "Tee" or "Four-way" under the pipe accessory positioning points based on the coordinates of the starting point. Determine the branch pipe diameter based on the number of sprinkler positioning points on the branch pipe and relevant specifications; traverse the water supply and drainage template library to obtain the pipe template of the corresponding diameter; use the created "Sprinkler System" node as input, call the pipeline creation through CAA, and complete the creation of the pipe branch. Step 5: Create a sprinkler pipe; obtain the nozzle positioning point by traversing the geometric shape set under the 3D shape; The sprinkler pipe's starting point is the nozzle's location point. The sprinkler pipe's ending point is calculated based on its length. Based on the sprinkler pipe's starting point coordinates, a corresponding feature point, "Tee," is created in the pipe accessory location point geometry set. The water supply and drainage pipe library is traversed to obtain a pipe template with the corresponding diameter. Using the created "Sprinkler System" node as input, CAA is used to call pipeline creation to complete the creation of sprinkler pipes. Then, sprinkler heads are created based on the sprinkler positioning points. Step 6: Install pipe accessories; obtain feature points in the pipe accessory positioning point geometry set; determine the pipe accessory type, parse the pipe specification parameters of the pipe accessory connection to obtain the specifications of the required pipe accessories; determine the pipe port connected to the pipe accessory based on the distance between the pipe accessory port and the ports at both ends of the pipe to be connected; traverse the pipe accessory template library to obtain pipe accessories of corresponding specifications; instantiate the obtained pipe accessories; adjust the spatial position and posture of the pipe accessories; and complete the connection between the pipe accessory and the pipeline.
