Description

Background Art

[0002] In construction projects, the design of various related engineering equipment is crucial. Due to the different geological conditions, environmental characteristics, and specific requirements of each project, it is difficult to directly reuse equipment between different projects. Therefore, after a project enters the substantive stage, equipment manufacturers usually need to carry out customized design according to the specific requirements of the project. This customization process makes it so that at the initial stage of construction drawing design, the specific structure of the equipment has not been finally determined, and the lack of customized equipment models poses certain challenges to the three-dimensional forward design of the project.

[0003] With the popularization and application of the three-dimensional forward design concept, engineering projects tend to pre-arrange the three-dimensional models of key equipment before construction drawing design to better coordinate the cooperation between different specialties. However, due to the lack of standard models that accurately reflect the external dimensions, interface positions, and dimension information of main equipment, similar models in historical projects are often relied on as references during the design stage. Although this method can meet the needs of preliminary design to a certain extent, it cannot accurately express the actual situation of the equipment in the new project. Especially in the design link connected to the auxiliary system part, only the traditional two-dimensional drawing conversion (i.e., model conversion) method can be relied on for three-dimensional modeling. This not only requires designers to add work steps, resulting in low forward design efficiency and designers' rejection of applying the three-dimensional forward design concept, but also cannot accurately express the external dimensions, interface orientations, and dimension information of the equipment required during the design process, easily causing errors and thus affecting the overall quality and progress control of project construction. Therefore, there is still room for improvement in the method for establishing the main equipment model.

[0004] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present disclosure, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art.

[0020] The present disclosure example proposes a solution to the lack of a device model in the early stage of design, that is, to establish an empty device engineering template. By establishing spatial points and lines to represent device ports, while ignoring the device entity shape and detailed geometric features, in the visualization window, there is no device entity. Through this method, the auxiliary system design in the early stage is completed. For the method for establishing the empty device model in the embodiment, on the one hand, the spatial interface points and their related support surfaces and support lines are defined by a parametric method, and the positions and sizes of these elements are accurately controlled by adjusting the constraints, so as to ensure the accurate position of the spatial interface points in the three-dimensional space, which is convenient for the connection design with other components in the later stage; on the other hand, through the parametric elevation information, the position information of the spatial interface points in the vertical direction is mapped to the corresponding support surfaces to ensure the correct height information of the interface points, thus avoiding installation problems caused by elevation differences; on the further hand, after determining the positions and types of the spatial interface points, interface information is further added to these interface points to form a primary empty device model containing all necessary interface information, which helps to understand and use these interface points in the later stage and improves the consistency and accuracy of the design; in addition, the primary empty device model already containing interface information is standardized into an engineering template, which is convenient for repeated use in multiple project nodes, reduces the time for re-designing each project, and improves the design efficiency; finally, according to the specific project requirements, the engineering template is instantiated under the project node, and necessary parameter adjustments and interface point optimizations are performed on the newly formed physical assembly to ensure that the model fully conforms to the actual situation of the current project, so as to generate an empty device model applicable to the project. Thus, the accuracy and reliability of the empty device model are further improved, and the delay of the design cycle caused by the lack of a device model in the early stage of the project is also avoided.

When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this specification.

[0041] Now, example embodiments will be described more fully with reference to the drawings. However, the example embodiments can be implemented in various forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be more thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art.

[0042] In addition, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of the embodiments of the present disclosure. However, those skilled in the art will recognize that the technical solutions of the present disclosure may be practiced without one or more of the specific details, or other methods, components, devices, steps, etc. may be employed.

[0043] In addition, the drawings are only schematic diagrams and are not necessarily drawn to scale. The block diagrams shown in the drawings are only functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities may be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0044] With the popularization and application of the three-dimensional forward design concept, engineering projects increasingly tend to pre-arrange the three-dimensional models of key equipment before the construction drawing design to better coordinate the cooperation between different specialties. However, due to the lack of standard models that can accurately reflect the external dimensions, interface positions, and dimension information of main equipment, similar models in historical projects are often relied on as references during the design phase. Although this method can meet the requirements of the preliminary design to a certain extent, it cannot accurately represent the actual situation of the equipment in the new project, especially in the design link connecting with the auxiliary system part, and only the traditional method of model conversion can be relied on for three-dimensional modeling. This method is not only inefficient but also cannot accurately represent the external dimensions, interface orientations, and dimension information of the equipment required during the design process, easily introducing errors and thus affecting the overall quality and progress control of the project construction.

[0045] In addition, in the actual design process, the design of the equipment and its connection parts is jointly completed by the design party and the equipment manufacturer. If the design activities of the equipment manufacturer are ignored during the design process, the actual design process cannot be truly reflected, and it is also not conducive to effective communication and cooperation among the participating parties.

[0046] At the same time, in the equipment and pipeline solution based on three-dimensional modeling software, when the main equipment model is missing, it will cause the interruption of the logical processes of auxiliary systems such as oil, gas, and water, which does not conform to the design concept of driving physics with logic in the three-dimensional modeling software.

[0047] To solve all or part of the above-mentioned technical problems in the related art, in the exemplary embodiments of the present disclosure, a method for establishing an empty equipment model is first provided. Figure 1A flowchart schematically shows a method for establishing an empty device model according to some embodiments of the present disclosure. Refer to Figure 1 As shown, the method for establishing the empty device model may include the following steps:

[0048] Step S110, ignoring the actual shape and size of the device, only establishing parameterized spatial interface points and the support surfaces and support lines that support the spatial interface points, and using adjustment constraints to control the orientation and dimension information of the spatial interface points, support surfaces and support lines. The spatial interface points represent the connection points between the device and external components;

[0049] Step S120, projecting the spatial interface points onto the corresponding support surfaces according to the parameterized elevation information;

[0050] Step S130, adding corresponding interface information to the spatial interface points according to the positions, types, etc. of the spatial interface points to obtain a primary empty device model;

[0051] Step S140, setting the primary empty device model as an engineering template;

[0052] Step S150, in the application stage, instantiating the engineering template of the empty device under the project node;

[0053] Step S160, performing parameter adjustment and interface point optimization on the instantiated assembly according to the project characteristics to obtain an empty device model suitable for a specific project.

[0054] Among them, an empty device refers to a three-dimensional model that does not express or only expresses very few device outer shapes and sizes, and focuses on expressing the detailed positions and connection directions of the oil, gas, and water pipeline interfaces for the connection between the device and the external auxiliary system. Since there may be nothing displayed at the actual device occupancy location, it is called an empty device. The goal of the empty device model is to provide a parameterized and standardized spatial representation for the installation and interface design of the device. In the embodiments of the present disclosure, the empty device may be a generator set device, or other industrial devices that require interface layout and spatial coordination, such as compressor sets, industrial cooling systems, industrial furnaces, reaction kettles, conveyor belt systems, fan devices, control cabinets, etc. A generator set may represent a combination of devices used to produce electrical energy in a power generation system. In the embodiments of the present disclosure, the generator set may be a hydro-generator set, or other generator sets that require three-dimensional modeling during the design stage, such as thermal power generator sets, nuclear power generator sets, etc. When establishing the empty device model, the 3DExperience (3DE) software platform can be used for modeling. Of course, in other embodiments of the present disclosure, other suitable three-dimensional design software can also be used for modeling.

[0055] In the actual operation process, first, parametric spatial interface points, as well as the support surfaces and support lines that support these interface points, are established, and their position and dimension information are precisely controlled by adjusting constraints. Then, according to the elevation information of the device, these spatial interface points are projected onto the corresponding support surfaces, ensuring the accurate position of the interface points in three-dimensional space. Next, according to the position and type of the spatial interface points, corresponding interface information (such as dimensions, types, materials, etc.) is added to them, thus constructing a primary empty device model that contains all necessary interface information. Secondly, the primary empty device model is standardized into an engineering template for repeated use throughout the design process. Finally, the engineering template is instantiated under specific project nodes, and according to the specific project requirements, necessary parameter adjustments and interface point optimizations are carried out on the instantiated physical assembly, and finally an empty device model that conforms to the actual situation of the current project is generated.

[0056] According to the method for establishing an empty device model in the above exemplary embodiment, on the one hand, the spatial interface points and their related support surfaces and support lines are defined by a parametric method, and the position and dimensions of these elements are precisely controlled by adjusting constraints, which can ensure the accurate position of the spatial interface points in three-dimensional space and facilitate the connection design with other components in the later stage; on the other hand, through parametric elevation information, the position information of the spatial interface points in the vertical direction is mapped onto the corresponding support surfaces to ensure the correct height information of the interface points, thus avoiding installation problems caused by elevation differences; on the further hand, after determining the position and type of the spatial interface points, interface information is further added to these interface points to form a primary empty device model that contains all necessary interface information, which helps to understand and use these interface points later and improves the consistency and accuracy of the design; in addition, the primary empty device model that already contains interface information is standardized into an engineering template for repeated use in multiple project nodes, reducing the time for re-designing each project node and improving the design efficiency; finally, according to the specific project requirements, necessary parameter adjustments and interface point optimizations are carried out on the instantiated physical assembly to ensure that the model fully conforms to the actual situation of the current project, and thus an empty device model suitable for this project is generated. Thereby, the accuracy and reliability of the empty device model are further improved.

[0057] Next, the method for establishing an empty device model in the above exemplary embodiment will be further described.

[0058] In step S110, the actual shape and size of the device are ignored, and only parametric spatial interface points and the support surfaces and support lines that support the spatial interface points are established, and the orientation and dimension information of the spatial interface points, support surfaces, and support lines are controlled by adjusting constraints. The spatial interface points represent the connection points between the generator set and external components.

[0059] Among them, the spatial interface points can represent one or more coordinate points defined in a three-dimensional space, which are used to represent the connection positions between the generator set and external components (such as pipelines, cables, valves, etc.). These points clearly identify the physical connection points between the generator set and other systems or components in the three-dimensional model. The support surface can represent one or more planes defined in the three-dimensional model, which are used to support and position the spatial interface points. These surfaces are generally non-existent virtual surfaces, and the purpose is to provide stable support for the interface points. The support line can represent a set of straight lines defined in the three-dimensional model, which are used to further clarify the position and direction of the spatial interface points. The support line is generally a virtual extension line of the external component and is used to define the connection direction of the interface point. Among them, the support surface ensures the accurate position of the spatial interface points in the three-dimensional space, and at the same time provides a reference plane for the spatial interface points, enabling them to be projected and adjusted on the correct plane. The support line can be used to determine the specific position of the spatial interface points. Especially in the case where the interface points need to be positioned along a specific direction, the support line can ensure that the spatial interface points are connected to the external components along the correct path. In addition, by ignoring the actual external dimensions of the device, complex external details can be ignored, enabling designers to focus on the layout and coordination of interfaces and connections, and making it easier to quickly adjust and optimize the position and orientation of the interfaces to meet the requirements of different projects.

[0060] Figure 2 Schematically shows a physical expression schematic diagram of an empty device model according to some embodiments of the present disclosure. Specifically, first, a set of spatial interface points are defined in the three-dimensional design software. These points represent the connection positions between the device and the external components, and at the same time, parameters such as X and Y coordinates are assigned to each spatial interface point to ensure that the positions of these points can be changed by adjusting the parameters. These parameters include but are not limited to coordinate values. Then, support surfaces are created in the three-dimensional design software. These surfaces are used to support the spatial interface points, and parameters such as elevation information and tilt angles are set for the support surfaces to ensure that the positions of the support surfaces can be adjusted as needed. Figure 3Schematically shown is a schematic diagram of an establishment interface of an empty device model engineering template according to some embodiments of the present disclosure, including components, inputs, meta-inputs, and parameters. Create support lines in 3D design software, which are used to further clarify the positions and directions of spatial interface points. Set parameters for the support lines, such as length, starting coordinate, ending coordinate, etc., to ensure that the positions of the support lines can be adjusted as needed. At the same time, associate the spatial interface points with the corresponding support lines to ensure that the positions of the interface points are consistent with the directions of the support lines. Finally, set adjustment constraints for each spatial interface point, support surface, and support line to ensure that their position and dimension information can be coordinated with each other. Through the adjustment constraints, it is convenient to change the position of the spatial interface point, the angle of the support surface, or the direction of the support line to ensure that the positional relationship of all elements in the 3D space is accurate. The adjustment constraints can represent methods for controlling the positions, directions, and dimensions of spatial interface points, support surfaces, and support lines.

[0061] In addition, when creating spatial interface points, the positions or dimensions of some interfaces may not be describable by simple numerical parameters. For example, the interface may need to be determined according to the positional relationship of other components, or need to meet specific geometric conditions. There are also some interface positioning information that is more suitable for expression on a 2D plane. For example, the interface may need to be in the same plane as other components, or need to meet specific angular relationships. For these interfaces that are difficult to express with numerical parameters or are more suitable for expression in a planar view, transfer them to a pre-defined sketch for operation. In the sketch, precisely control the position and dimension of the interface by adding and adjusting constraint conditions, such as distance, angle, parallel, perpendicular, etc.

[0062] In some embodiments, when the device is a hydro-generator unit, the spatial interface points can correspond to other suitable unit interfaces such as the inlet pipe interface of the bearing cooler, the drain pipe interface of the water guide bearing cooler, the inlet pipe interface of the thrust lower guide bearing cooler, the drain pipe interface of the thrust lower guide bearing cooler, the inlet oil pipe interface of the thrust lower guide bearing cooler, the outlet oil pipe interface of the thrust lower guide bearing cooler, the inlet pipe interface of the upper guide bearing cooler, the drain pipe interface of the upper guide bearing cooler, the inlet pipe interface of the generator air cooler, the drain pipe interface of the generator air cooler, the lubrication and cooling water supply pipe interface of the upper seal ring, and the lubrication and cooling water supply pipe interface of the lower seal ring.

[0063] In some embodiments, establishing parameterized spatial interface points and support surfaces and support lines for supporting the spatial interface points specifically includes the following steps: Switch the modeling software to the part environment, and use the modeling software to establish parameterized spatial interface points and support surfaces and support lines for supporting the spatial interface points; Define the spatial positions of the preset spatial interface points using coordinate parameters.

[0064] Among them, the part environment can represent a specific mode or interface in 3D modeling software, allowing users to create and edit the geometry of a single part in a separate and enclosed environment.

[0065] Specifically, in the main interface of the software, select "New Part" or a similar option to switch the modeling software to the part environment. Select a plane (such as the XY, XZ, YZ plane or other planes) as the basis for sketching, and then enter the sketching mode. Draw spatial interface points representing the connection points between the device and external components in the sketch, use the plane creation tool to define the support surface, and use the line creation tool to define the support line. Define the position of the spatial interface points by entering specific coordinate values, that is, determine the exact position of the interface points in the three-dimensional space by specifying the X, Y, and Z coordinate values.

[0066] In some embodiments, adjustment constraints are used to control the orientation and dimensional information of the spatial interface points, support surfaces, and support lines. The specific steps are as follows: Switch the modeling software to the sketch environment, and use dimensional constraints and reference constraints to control the position of the spatial interface points; use geometric constraints to control the orientation of the support lines; use dimensional constraints to control the dimensions of the support surfaces and support lines.

[0067] Among them, dimensional constraints can be used to control the specific numerical attributes of geometric elements in the model, such as length, width, height, radius, diameter, etc. These constraints ensure that the dimensions of the geometric elements remain unchanged during the design process and can be adjusted as needed. Reference constraints can be used to define the positional relationship of elements in the model relative to other elements. Geometric constraints are used to control the geometric relationships between geometric elements in the model, such as parallel, perpendicular, collinear, concentric, etc. They can ensure that the relative positional relationships between geometric elements remain unchanged during the design process and can be adjusted as needed.

[0068] Specifically, in the sketch environment, set the X and Y coordinate parameters for the spatial interface points to ensure that the position of the spatial interface points on the selected plane can be adjusted at any time. Define the position of the spatial interface points relative to a certain reference plane or reference line. For example, offset constraints can be used to ensure that the interface points are at a specific distance from a certain reference plane or reference line. When using geometric constraints to control the orientation of the support surfaces and support lines, parallel constraints can be used to ensure that the support surface is parallel to a certain reference plane, perpendicular constraints can be used to ensure that the support surface is perpendicular to a certain reference plane, and collinear constraints can be used to ensure that the edge of the support surface is collinear with a certain reference line. When using dimensional constraints to control the dimensions of the support surfaces and support lines, length parameters, width parameters, and height parameters can be set for the support lines to ensure that their dimensional information meets the design requirements.

[0069] In step S120, project the spatial interface points onto the corresponding support surfaces according to the parameterized elevation information.

[0070] Among them, the elevation information can represent the height of a certain spatial interface point relative to a certain reference plane in a three-dimensional space, usually represented by the Z coordinate. Specifically, when projecting the spatial interface point onto the corresponding support surface, first determine the elevation information of each spatial interface point, and then project the spatial interface point onto the corresponding support surface to ensure the accurate position of the interface point in the vertical direction. Among them, Z is a modifiable parameter. By modifying the value of the Z parameter, the spatial interface point will automatically update its elevation information, that is, the value of the Z coordinate, so as to ensure the accurate position of the interface point. In the actual operation process, only need to modify the value of the interface elevation in the parameter set, and the model will be automatically updated, and the interface point will be projected onto the corresponding support plane according to the new elevation information. This avoids manual adjustment of the interface position, improves the design efficiency, and the parameterized elevation information is convenient for management and modification to adapt to the changes in the project design process.

[0071] In step S130, according to the position and type of the spatial interface point, add corresponding interface information to the spatial interface point to obtain a primary empty device model.

[0072] Specifically, determine the type of the interface, such as input interface, output interface, input-output interface, etc., according to the function and connection requirements of the spatial interface point, and add corresponding interface information to the spatial interface point.

[0073] In some embodiments, according to the position and type of the spatial interface point, add corresponding interface information to the spatial interface point to obtain a primary empty device model, which specifically includes the following steps: establish a device type model, and set ports representing device interfaces in the device type model; perform attribute settings on the ports and associate the ports with the spatial interface points; according to the position and type of the spatial interface point, add corresponding type information, dimension information, position information and function information to the spatial interface point to obtain a primary empty device model.

[0074] Specifically, refer to Figure 4 As shown, when establishing the device type model, the user can select or input a custom device type, name the device type, such as physical product 00897789, select the category of the device, such as physical device, etc., and further define the part subtype. In addition, refer to Figure 5As shown, when setting the device interface port, the user can define the port name, specialty, select the port type (such as "digital" or "analog"), define the endpoints of the geometric figure, alignment and direction, and can also specify the logical type of the port (such as "input" or "output") and the connection method to the device. In addition, the user can view the set port information, including the port number, attributes, and port description. In the pipeline part environment, convert the model to the device type, create ports representing the device interface on the device body, and determine the position of the ports on the device body according to the position information of the space interface points. Dimension constraints and reference constraints can be used to precisely control the position of the ports. Set attributes for each port, including but not limited to type information, dimension information, material information, function information, etc. For example, attributes such as the diameter, thickness, and material of the port can be set. Associate the ports on the device body with the space interface points to ensure that the position relationship between each port and the corresponding space interface point is correct. Then, according to the function and connection requirements of the space interface points, determine the type information of the interface, such as input interface, output interface, input-output interface, etc.; at the same time, add corresponding dimension information and position information to the space interface points to obtain a primary empty device model.

[0075] In some embodiments, after projecting the space interface points onto the corresponding support surface, the following steps are further included: adding non-geometric parameter information to the primary empty device model, and the non-geometric parameter information includes any one or more of device attributes, performance parameters, material attributes, data interface parameters, and design parameters.

[0076] Specifically, adding the non-geometric parameter information to the primary empty device model can be conveniently passed to downstream specialties, such as the civil engineering specialty for structural design and the electrical specialty for electrical calculations, etc. It avoids errors and omissions in the information transfer process and improves the design efficiency and accuracy.

[0077] In step S140, set the primary empty device model as an engineering template.

[0078] Among them, the engineering template can represent a pre-designed standard model containing specific design elements and parameter information.

[0079] In some embodiments, setting the primary empty device model as an engineering template specifically includes the following steps: setting the primary empty device model as an engineering template, using the basic axis system or key points and lines of the empty device as input conditions, and using the control parameters of the target geometric features and interface features expressing the empty device as input parameters.

[0080] Among them, the basic axis system can represent the coordinate system in the empty device model, including the main axes and auxiliary axes, such as the X-axis, Y-axis, and Z-axis. These axis systems are used as the benchmarks to determine the position and orientation of the device in space. The key points can represent some important geometric points defined in the empty device model, which are used to determine the position, interfaces, or connection positions of the device. The key points can include: mounting points, that is, the specific points used to mount the device or connect other components; center of gravity points, that is, the points used to identify the center of gravity position of the device, which is particularly important when considering the stability of the device in the design; interface points, that is, the positions defining the connection between the device and external subsystems (such as pipelines, electrical interfaces, etc.). The key lines can represent some important geometric lines in the device model, which are used to define lengths, directions, or boundaries, etc. The key lines can be mounting reference lines and positioning lines, etc. The target geometric features can be used to define the geometric shape, size, and spatial position of the device model, and are the main description and control features of the device during the design process, such as the external contour, dimensional features, geometric symmetry, and feature surfaces, etc. The interface feature control parameters can be used to describe the interface characteristics between the device and the external environment or other components, ensuring the compatibility and correct connection between different components, such as mechanical interfaces, electrical interfaces, and fluid interfaces, etc. Specifically, in the engineering template of the modeling software or similar applications, select the option of "Add Reference" or similar, and save the primary empty device model as an engineering template file. Obtain the basic axis system or key points and lines of the device as input conditions, and set control parameters according to the design requirements, such as dimensional constraints, geometric constraints, etc., to ensure that the template can correctly adapt to different installation conditions.

[0081] In step S150, in the application stage, instantiate the engineering template of the empty device under the project node.

[0082] Specifically, the purpose of instantiating the engineering template under the project node is to reuse the standardized device design or model in the actual project workflow. Automatically match based on the basic axis system in the engineering template and the coordinate system in the project node. The software tool can automatically align the model based on the coordinate axes. For example, during the instantiation process, align the central axis of the template with the predetermined central axis in the project node. Figure 6Schematically shown is an interactive interface diagram for an empty device model according to some embodiments of the present disclosure. At the top part of the interface, it is labeled "Reference: Empty Device - Main Shaft Seal A.1". This indicates that the object currently in use is "Empty Device - Main Shaft Seal A.1". This interface is used to instantiate the "Empty Device - Main Shaft Seal A.1" device into the project. During the instantiation process, the position of the device is aligned by defining input conditions (such as the X-axis and the coordinate origin) to ensure its correct installation in three-dimensional space. Using the coordinate origin and the direction axis as a reference, precise positioning of the device can be achieved. The "Installation Elevation" and "Interface Elevation" displayed in the parameter window are used to ensure that the vertical positions of the device and the interface in the project are correct. At the same time, these parameters can also be dynamically adjusted through formulas, thereby automatically calculating the appropriate installation height according to the requirements of the project. This parametric control can greatly reduce the workload of manual adjustment and improve the efficiency of design and construction.

[0083] In some embodiments, instantiating the engineering template of the empty device under a project node includes: instantiating the engineering template under the project node according to the basic shafting or key points and lines of the empty device.

[0084] Specifically, according to the project management plan, determine the project node where the template needs to be inserted, establish the basic shafting or key points and lines required for inserting the template under the node, and then select the basic shafting or key points and lines to instantiate the engineering template under the project node. At this time, a new device exactly the same as the device in the engineering template has been generated. Then, according to the characteristics of the device itself, adjust the position and geometric parameters in the template, such as the X, Y, and Z coordinates, to ensure that the template is correctly placed at the specified node position. Under the professional node of the project, create the geometric elements (basic shafting, points, lines, etc.) required for inserting the engineering template, select the engineering template and sequentially select the corresponding geometric elements to complete the rapid creation of a new empty device model suitable for this project.

[0085] In step S160, parameter adjustment and interface point optimization are performed on the instantiated physical assembly according to the project characteristics to obtain an empty device model suitable for a specific project. Figure 7 and Figure 8 represents the real device model, and Figure 2 the empty device model in Figure 8 corresponds to the real device model in Figure 10 the empty device model in Figure 7 corresponds to the real device model in

[0086] Specifically, by adjusting the parameters of the engineering template and optimizing the interface points, an empty device model that meets the requirements of the current project can be quickly generated, improving the design efficiency. By optimizing the interface points, the connection between devices and between devices and external systems is made more compact and reliable, reducing the risk of interface mismatch. By adjusting the parameters of the template, the accuracy of the model in terms of geometric and non-geometric parameters can be ensured, improving the quality of the model.

[0087] In some embodiments, parameter adjustment and interface point optimization are performed on the instantiated physical assembly according to the project characteristics, including: according to the project characteristics, under the parameter set of the structure tree, adjusting the layout elevation of the device, the size of auxiliary devices, and the device model; in the sketch environment, adjusting the position of the spatial interface points by adjusting the constraint values.

[0088] Specifically, determine the parameters related to the layout elevation of the device, the size of auxiliary devices, and the device model in the parameter set of the structure tree, and input the correct elevation value, size, and device model according to the elevation information, size information, and device model information provided by the project. Then, select the sketch containing the spatial interface points in the model, enter the sketch editing mode, select the spatial interface points to be adjusted in the sketch, and adjust the values of the dimension constraints or geometric constraints according to the position information provided by the project nodes to ensure the accurate position of the spatial interface points.

[0089] In some embodiments, after performing parameter adjustment and interface point optimization on the engineering template, the following steps are further included: under the parent node of the empty device, replace the empty device with a real device model and assemble the pipeline connected to the real device model and the empty device model; establish a connection relationship between the pipeline connected to the empty device and the real device, thereby completing the assembly of the overall device.

[0090] Among them, the real device model can represent a three-dimensional model established based on the physical dimensions, structural layout, interface positions, and other relevant attributes required for construction, installation, and operation and maintenance of the actual device, such as the three-dimensional model provided by the device manufacturer. In the actual operation process, first select the assembly function in the modeling software, enter the assembly environment, select the empty device on the structure tree, select the replacement command, and then select the real device model to complete the replacement of the device. After replacement, check the pipelines and parts originally connected to the empty device. If the connection relationship between the pipelines and parts and the real device model is disconnected, select the interface of the real device model and re-establish the connection relationship with it.

[0091] The method for establishing the empty equipment model in the above exemplary embodiment, on the one hand, defines the spatial interface points and their related support surfaces and support lines through a parametric method, and precisely controls the positions and dimensions of these elements by adjusting the constraints, so as to ensure the accurate positions of the spatial interface points in the three-dimensional space, facilitating the connection design with other components in the later stage; on the other hand, through the parametric elevation information, maps the position information of the spatial interface points in the vertical direction to the corresponding support surfaces, ensuring the correct height information of the interface points, thus avoiding installation problems caused by elevation differences; on the further hand, after determining the positions and types of the spatial interface points, further adds interface information to these interface points to form a primary empty equipment model containing all necessary interface information, which helps to understand and use these interface points in the later stage, improving the consistency and accuracy of the design; in addition, standardizes the primary empty equipment model containing interface information into an engineering template, facilitating repeated use in multiple project nodes, reducing the time for re-designing each project node, and improving the design efficiency; finally, according to the specific project requirements, makes necessary parameter adjustments and interface point optimizations to the physical assembly after instantiating the engineering template, ensuring that the model fully conforms to the actual situation of the current project, and generating an empty equipment model applicable to this project. Thus, further improving the accuracy and reliability of the empty equipment model.

[0092] In addition, adding non-geometric parameter information (such as equipment attributes, performance parameters, material attributes, etc.) to the primary empty equipment model can make the model more comprehensive and practical, which provides an important reference basis for later manufacturing, installation, and operation and maintenance. By establishing an equipment type model and setting ports representing equipment interfaces therein, and setting attributes for the ports and associating them with the spatial interface points, a more practical primary empty equipment model can be generated, making the model not only have a geometric form but also reflect the functional characteristics and physical attributes of the equipment. Finally, after obtaining the real model of the equipment, replaces the empty equipment with the real equipment model and assembles the real equipment model with the pipelines or parts originally connected to the empty equipment model, thereby obtaining the final assembly model, effectively verifying the feasibility and rationality of the model.

[0093] In addition, in the embodiments of the present disclosure, a method for applying the empty equipment model is also provided, and this application method can be used for the empty equipment model in the above embodiments. Taking the empty equipment model of a certain hydro-generator unit as an example, as shown in Figure 9 the application method of the empty equipment model of the generator set may include the following steps:

[0094] Step S910, perform instantiation processing on the empty equipment model of the generator set. Specifically, according to the project characteristics, select a suitable empty equipment model, Figure 10Schematically shows a schematic diagram of the physical expression of an air equipment model for a hydro-generator unit, including a coordinate system and geometric markings, which are used to accurately describe the installation position, interfaces, and alignment relationships of the equipment. Then, based on the civil engineering design model, the original control points and control lines of the air equipment are determined. The control points can be selected at the center point of the installation elevation of the unit, and the control line is selected as the center line of the unit to ensure that the position and orientation of the air equipment meet the requirements of the civil engineering design model. According to the controlled dimensions of the project's powerhouse, modify the parameters in the equipment template, such as installation elevation, diameter of the turbine floor pier, elevation of the turbine floor, elevation of the volute floor, etc. For other interface elevations of the equipment, confirmation can be made with the equipment manufacturer. Figure 11 Schematically shows a schematic diagram of the establishment interface of an air equipment model for a hydro-generator unit, which shows a schematic diagram of the establishment interface of "Unit Water Supply - Unit Cooler Assembly A.1" in an engineering design software, including multiple input conditions and parameter information. The input conditions include the X-axis (line) and the coordinate origin (point), and the parameters include installation elevation (length), diameter of the turbine floor pier (length), elevation of the turbine floor (length), elevation of the volute floor (length), elevation of the upper guide cooler water supply pipe interface (length), elevation of the upper guide cooler drain pipe interface (length), elevation of the air cooler water supply pipe interface (length), elevation of the air cooler drain pipe interface (length), elevation of the upper seal ring interface (length), and elevation of the lower seal ring interface (length).

[0095] In step S920, adjust the interface orientation in the air equipment model of the generator set. Specifically, find the "parameter set" node on the structure tree and find the control parameters and attribute parameters related to the interface position. According to the design requirements, modify the values of these parameters, such as the height and angle of the interface. Enter the sketch environment of the interface plane position on the structure tree and adjust the position of the interface point by modifying the constraint conditions in the sketch, such as dimension constraints and angle constraints. After modifying the parameters and constraints, the air equipment model of the hydro-generator unit will be automatically updated, and the interface position will change accordingly. By modifying the parameters and constraints, the interface position of the air equipment model can be flexibly adjusted to meet the design requirements, thus providing a convenient and fast interface adjustment method for designers and improving the design efficiency.

[0096] Step S930: According to the interface connection relationship, conduct the logical-to-physical connection of the oil, gas, and water auxiliary system. Specifically, according to the project requirements and design specifications, determine the logical processes and functional requirements of the auxiliary systems such as oil, gas, and water. For example, determine the equipment that needs lubrication in the oil system, the equipment that needs cooling in the gas system, the equipment that needs cooling water in the water system, etc. According to the results of the logical design, arrange the corresponding auxiliary equipment and pipelines in the empty equipment model of the generator set, and connect the auxiliary equipment and pipelines to the interfaces of the empty equipment model of the water turbine generator set. Through the connection from interface to interface between equipment, achieve the functional connection between each auxiliary system, ensuring that each system can operate normally according to the design requirements, such as lubrication, cooling, water supply, etc. Through logical design and physical design, achieve the functional connection of the auxiliary systems such as oil, gas, and water, providing guarantee for the integrity and accuracy of the empty equipment model of the water turbine generator set. Figure 12 Schematically shows an interactive interface diagram for the empty equipment model of a water turbine generator set. Among them, the parameter setting window contains multiple installation parameters of the equipment. These parameters are used to determine the specific geometric position and interface characteristics of the equipment. The schematic diagram of the 3D model of "Unit System - Unit Cooler Foundation A.1" is shown at the bottom of the interface, and the geometric shape of the equipment arranged in space and the reference coordinate system can be seen.

[0097] Step S940: Obtain the complete project model based on the real equipment model. Specifically, after obtaining the real model of the equipment, under the project structure tree, replace the empty equipment with the real equipment model, and assemble the real equipment model with the pipelines or parts originally connected to the empty equipment model. After inserting the real equipment model, the complete model of the entire project can be obtained. This model contains all the equipment and systems of the project and can be used for subsequent design, analysis, and operation and maintenance management work. By adding the real equipment model, improve the model information of the entire project, providing a basis for project handover and operation and maintenance management.
