The results of digital engineering design include design specifications, drawings, equipment lists, cost reports, etc. in the traditional sense, as well as digital engineering models, which can be used for construction, production and operation and maintenance management, etc. Components are the smallest units that constitute the content of digital engineering design, such as motors, pumps, valves, flanges, doors, windows and individual, inseparable special engineering elements commonly used in coal mine engineering design.

DETAILED DESCRIPTION

[0018] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0019] Specifically, the component model generation method and device based on three-dimensional design software according to an embodiment of the present disclosure will be described below with reference to the accompanying drawings.

[0020] Figure 1 The following is a flow chart of a component model generation method based on 3D design software provided by an embodiment of the present disclosure. Figure 1 As shown, the component model generation method based on 3D design software may include the following steps: Step 101: register the model of the component to be modeled in the three-dimensional design software.

[0021] In some embodiments of the present disclosure, the 3D design software may be MicroStation (2D and 3D CAD design software). It should be noted that when modeling in the 3D design software, it is necessary to associate the customized component model with the development framework of the 3D design software by registering the model, so that the design software can recognize, manage and use the customized model.

[0022] As an example, please refer to Table 1 for registering model-related classes.

[0023]

[0024] Step 102: Create a data class of the model, where the data class is used to define model parameters of the model.

[0025] It should be noted that the data class refers to a class used to store and manage component-related data.

[0026] Step 103: Acquire reference data of the component to be modeled based on the component database.

[0027] Among them, the component database stores relevant data of the components, such as performance model parameters related to component selection, and geometric model parameters for controlling the appearance of the components. In some embodiments of the present disclosure, when constructing a component database, a corresponding data storage method can be selected according to the parameter characteristics of the component, and a data query method can also be provided. As an example, when there is a functional dependency between component data, and the data volume is large and the maintenance frequency is high, a relational database management system can be used for component data storage, such as SQL Server, SQL Lite and other database management software, to minimize data redundancy. Taking the asynchronous motor as an example, the reference data related to a certain asynchronous motor has a certain functional dependency, and the data volume is large, so the data storage method of a relational database can be used. Figure 2 This is a schematic diagram of the data table relationship of a certain asynchronous motor provided by the embodiment of the present disclosure. When the amount of component data is limited, the maintenance frequency is low, and there is no function dependency, it can be stored in the form of files such as txt, xml, excel, etc.

[0028] As a possible line of sight method, after the component to be modeled is determined, the name of the component to be modeled can be used as a query condition to query and obtain reference data of the component to be modeled in the component database.

[0029] Step 104 , assigning values ​​to first geometric model parameters in the data class according to the reference data, wherein the assigned first geometric model parameters include a plurality of geometric body information constituting the component to be modeled and key point information corresponding to each geometric body information.

[0030] It should be noted that in the embodiments of the present disclosure, a component can be regarded as consisting of multiple basic geometric bodies, such as a component consisting of a cylinder and a step. The key point information corresponding to the geometric body information can be understood as the reference point of each geometric body, which is used to represent the connection relationship between the geometric bodies in the component. As an example, taking the output shaft and the shoulder of the motor as two geometric bodies, if the key point of the output shaft is (0, 0, 0), then the key point of the shoulder is (output shaft length, 0, 0), and it is only necessary to generate the output shaft and the shoulder at the key point position. The two basic geometric bodies of the output shaft and the shoulder can be "combined" together through the key points of the two geometric bodies.

[0031] Figure 3 A schematic diagram of key points of a model provided in an embodiment of the present disclosure. Figure 3 Taking a certain component in a motor as an example, 9 key points are set. In some embodiments, one of the key points can be set as a model placement point (i.e., the position of the mouse cursor in the graphics space) to achieve model placement. Figure 3 The meaning of each key point can be found in Table 2.

[0032]

[0033] In addition, in some embodiments of the present disclosure, the data class may include first performance model parameters in addition to the first geometric model parameters. The first performance model parameters in the data class are assigned values ​​according to the reference data in the component database. The first performance model parameters are attached to the model in the form of associated information. The first performance model parameters include, for example, model name, manufacturer name, equipment price, voltage, current, etc.

[0034] Step 105 , generating a plurality of three-dimensional geometric bodies according to a geometric body generation function and a plurality of geometric body information in a software development kit corresponding to the three-dimensional design software.

[0035] Taking MicroStation as an example, the corresponding software development kit is MicroStation SDK. In some embodiments of the present disclosure, the basic three-dimensional geometric body can be obtained by stretching, rotating, scanning, lofting, etc. of a two-dimensional surface and then by certain Boolean operations.

[0036] In some embodiments of the present disclosure, the geometric body generation function may include a two-dimensional geometric body generation function and a three-dimensional geometric body generation function, which are respectively used to generate a two-dimensional geometric body and a three-dimensional geometric body according to geometric body information. Different geometric body types have their own corresponding two-dimensional geometric body generation functions.

[0037] As a possible implementation method, the geometric body type to which each geometric body information in the component to be modeled belongs can be determined, such as a cylinder, a cuboid, a step, etc. According to the geometric body type, a target two-dimensional geometric body generation function corresponding to each geometric body information is determined in the two-dimensional geometric body generation function. The target two-dimensional geometric body generation function is used to generate a two-dimensional geometric body corresponding to each geometric body information, and the three-dimensional geometric body generation function is used to stretch each two-dimensional geometric body to generate multiple three-dimensional geometric bodies.

[0038] Taking asynchronous motor as an example, for cylindrical geometry type, ICurvePrimitive::_CreateArc function in the software development kit can be used to generate a two-dimensional circle, for rectangular geometry type, ICurvePrimitive::CreateLineString function can be used to generate a two-dimensional polygon, and ISolidPrimitive::CreateDgnExtrusion function can be used to stretch the two-dimensional graphics to generate a three-dimensional geometry. If Boolean operations are to be performed on three-dimensional geometry, the BodyFromSolidPrimitive function can be used to convert the ISolidPrimitive class to the ISolidKernelEntityPtr class. Common entity operations are implemented through the SolidUtil::Modify class, mainly including cutting (BooleanCut), merging (BooleanUnion), subtracting (BooleanSubtract), thickening (ThickenSheet), chamfering (BlendEdg es), transforming (TransformBody), etc., among which the changes can realize operations such as moving, copying, mirroring, and rotating the body.

[0039] Step 106 , combining multiple three-dimensional geometric bodies based on the key point information to generate a model of the component to be modeled.

[0040] Optionally, in some embodiments of the present disclosure, the present disclosure can also customize the control points of the model. The control points refer to the interactive operation of the model by clicking the mouse after the model is selected. In one implementation, the control points of the model can be defined using the m_controls class in the software development kit, and the control points are used to perform interactive operations on the model. The assignment information of the software user to the m_locations variable in the m_controls class is obtained. The number of control points of the model is determined according to the assignment information.

[0041] Optionally, in some embodiments of the present disclosure, the model can also be placed and / or added through the basic tool class in the software development kit. Taking the design software MicroStation as an example, the component model can be added and / or placed through the component model placement and addition tool PlaceMotorTool derived from the basic tool class DgnPrimitiveTool. Among them, the main functional functions of the component model placement and addition tool PlaceMotorTool include: A. Implement the loading of tools and interfaces in the override function of _OnPostInstall.

[0042] B. The rewritten function of _OnDynamicFrame implements dynamic placement of the model, and calls a unified model generation function to achieve the dynamic effect of the model following the mouse rotation. The model displayed by the dynamic effect may be different from the actual model.

[0043] C. The _OnDataButton function defines the left mouse button action. By clicking the left mouse button in the graphic space, the placement information required to create the object model is passed to the model generation function, and the model is added to the current graphic space. You can set it to add the model by clicking the left mouse button once, or you can add the model by clicking the left mouse button multiple times.

[0044] D. The _OnRestartTool function defines the mouse right button action to reload the model placement tool after right clicking the mouse.

[0045] The placement information can be obtained through the position of the mouse cursor, and the position and orientation of the model in the graphic space are determined by the placement information. The placement information of the model includes four information: origin, deflection angle, pitch angle, and roll angle.

[0046] Optionally, in some embodiments of the present disclosure, in order to meet the needs of model expression and facilitate the modification of the model display state, the display style of the model can be defined using an element template in the 3D design software. Input operation information of the software user in the element template is obtained, and the display style of the model is determined according to the input operation information. Figure 4 A schematic diagram of an element template definition interface provided by an embodiment of the present disclosure. Figure 4 As shown in the figure, the element template defines the element's layer, line type, color, material, section pattern, etc., and the component model can be displayed in the specified style. If the graphic platform does not have the element template function, the model's layer, line type and other information can be predefined in the code.

[0047] By implementing the embodiments of the present disclosure, the component model is generated through the component data and the geometric body generation function, realizing the data-driven model, unifying the model data format, and improving the modeling efficiency and modeling accuracy. In addition, the present disclosure also optimizes the model storage method. Compared with storing the graphic information of the component, the present disclosure stores the component data required for modeling in the component database, which reduces the storage space and is more convenient for model management, maintenance and sharing.

[0048] In actual work scenarios, the model needs to be dynamically adjusted according to different project requirements, such as reducing a certain component, modifying size parameters, etc. However, the methods of providing the model by the component manufacturer, downloading the model from the Internet, and saving the model after the designer models it in a graphical way all have the problem that the model cannot be modified dynamically, and a new model needs to be recreated according to the project requirements. To solve this problem, the present disclosure proposes another component model generation method based on 3D design software, which can be modified based on the generated model.

[0049] Figure 5 FIG. 1 is a flow chart of another component model generation method based on 3D design software provided by an embodiment of the present disclosure. Figure 5 As shown, in Figure 1 Based on the illustrated embodiment, the component model generation method may further include the following steps: Step 501: Create a model attribute class, which is used to define the attributes of the model.

[0050] In some embodiments of the present disclosure, an EC (Engineering Content) property file in XML format may be created, and a property class of the model may be created in the EC property file. Optionally, the properties of the model may include a second geometric model parameter and a second performance model parameter. The second geometric model parameter is related to the appearance of the model, such as structure and size, and the second performance model parameter may include model name, manufacturer name, equipment price, voltage, current, etc.

[0051] Step 502: rewrite the SetValue function in the attribute class to assign a value to the second geometric model parameter in the attribute class based on the assigned first geometric model parameter.

[0052] This step can be implemented after assigning values ​​to the data class in step 104. Taking the design software MicroStation as an example, the attribute class can be defined by the MotorElementECDelegate class, which is derived from the ElementECDelegate class in the software development kit. Figure 6The following is a schematic diagram of the functions that need to be implemented in the MotorElementECDelegate class. The SetValue function can be used to obtain the value of the first geometric parameter after the assignment in the data class, and the second geometric model parameter in the attribute class can be assigned based on the assigned first geometric model parameter. The attribute file after the assignment can be referenced. Figure 7 .

[0053] Optionally, in some embodiments of the present disclosure, the second performance model parameter in the attribute class may be assigned a value based on the first performance model parameter assigned in the data class in the same manner as described above.

[0054] Step 503: Acquire the property modification operation information of the software user, and update the assigned second geometric model parameters according to the property modification operation information.

[0055] Step 504 , rewrite the Commit function in the attribute class to update the first geometric model parameters according to the updated second geometric model parameters, and regenerate the model of the component to be modeled according to the updated first geometric model parameters.

[0056] The specific implementation method of regenerating the model of the component to be modeled according to the updated first geometric model parameters can be referred to step 105 and step 106, which will not be described in detail here. Figure 8 This is a schematic diagram of the original model before modification provided in the embodiment of the present disclosure. Fig. 9 This is a schematic diagram of a modified model provided by an embodiment of the present disclosure. Figure 8 and Fig. 9 As shown in the figure, change "without bearing temperature sensor" to "with bearing temperature sensor" and adjust the model appearance by modifying the properties.

[0057] Fig.10 A schematic diagram of creating a component model provided by an embodiment of the present disclosure. Fig. 9 As shown, through the steps of registering models, defining data classes, defining attribute classes, model expression, and model placement, a data-driven model is realized without the need to draw models through graphics, which greatly improves modeling efficiency.

[0058] By implementing the embodiments of the present disclosure, based on the user's attribute modification operation information, the second geometric model parameters in the attribute class and the first geometric model information in the data class are updated, the component model is regenerated, and the model is dynamically adjusted, thereby achieving the effect of being able to modify the geometric appearance of any model after it is added to the graphic space.
