Description

Technical Field

[0001] This application belongs to the field of shipbuilding technology, specifically relating to a rapid modeling method, apparatus, equipment and medium for shipbuilding processes. Background Technology

[0002] With the development of the shipbuilding industry, my country maintains a leading position globally in three major indicators: shipbuilding completion volume, new order volume, and order backlog. To control ship weight and improve internal space utilization, high-strength thin plates are being widely used in shipbuilding. Therefore, how to quickly establish a thin plate production line model for later manufacturing has become a key focus in the shipbuilding industry.

[0003] The existing modeling method for thin plate production line workshops relies on the plan layout to create physical models of workshop elements. Traditional modeling methods require creating a large number of physical feature points to form lines, lines to form surfaces, and then surfaces to form solids to create the model.

[0004] Current thin-plate production line modeling methods rely on physical characteristics, requiring a large amount of input dimensions, resulting in complex and time-consuming model creation. Furthermore, 2D references cannot be reused during creation, necessitating custom modeling constraints. Static simulation and resource intervention are also impossible, making errors prone to occur during actual construction and production. Therefore, how to quickly build thin-plate production line models and how to test the model's usability and safety during the modeling process are pressing issues that need to be addressed in this field. Summary of the Invention

This application integrates 2D layout drawings with a 3D modeling environment, making modeling references more intuitive and reducing the difficulty of modeling in thin-plate line workshops. It also greatly facilitates the modeling layout in thin-plate line workshops, shortens modeling time, improves modeling efficiency, and provides a foundation for the construction environment of thin-plate sections in ships.

[0048] The rapid modeling method, apparatus, equipment, and medium for the ship hull manufacturing process provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0049] Example 1

[0050] Figure 1 This is a flowchart illustrating the rapid modeling method for the ship hull manufacturing process provided in Embodiment 1 of this application. Figure 1 As shown, the specific steps include the following:

[0051] S101, obtain site planning information for the hull, tooling information, and tooling deployment information.

[0052] Firstly, this solution can be used on smart terminals, such as smartphones, tablets, or desktop computers, when designers are creating thin plate line workshop models using the editing interface of thin plate line workshop modeling software. The thin plate line workshop can be the deck of a ship. Since the thin plate line workshop modeling editing interface can include toolbars, display panels, and model editing panels, designers can select the desired tools through the toolbar, such as inserting required resources. Resources can be adjusted in the display panel, such as moving inserted tooling parts. Each tooling part generates a spatial model after adjustment, which is then displayed in the model editing panel.

[0053] Based on the above usage scenarios, it is understandable that the executing entity of this application can be the smart terminal, and no further restrictions are imposed here.

[0054] In this design, the hull can be a vehicle capable of navigating or anchoring in waterways for transportation or operations. Its interior mainly includes storage space, support structure, and drainage structure, and it has a propulsion system that utilizes external or its own energy source.

[0055] Site planning information can be a workshop layout plan of the ship's hull, which may include the workshop outline and dimensions. The purpose of obtaining site planning information is to determine the size and shape of the workshop in order to facilitate subsequent tooling placement and hull modeling.

[0056] Tooling information can refer to information about equipment used by ships during water operations, including tooling part numbers, names, dimensions, and appearance. Tooling parts can include cranes, forklifts, and containers, among others. Tooling information can be stored in a database table, either from the system's built-in process component library or in a separate database table created by the user after designing the tooling.

[0057] Tooling deployment information can include the location and quantity of tooling components within the hull. Specifically, this can be represented by a plan layout diagram. The location can be represented using coordinates, including absolute coordinates, relative coordinates, and relative polar coordinates. In this scheme, absolute coordinates are used. Absolute coordinates use point O as the origin and reference point to pinpoint the specific location of a point in the plane, represented as A(X, Y). For example, if the center of the ship's workshop is taken as the origin O, the coordinates are represented as (0, 0).

[0058] Acquisition can be the process of gathering site planning information for the ship's hull, tooling information, and tooling deployment information. Specifically, this can be done through the Plant Layout module of 3D modeling software. It allows for direct insertion of workshop floor plans or generation of resources from existing resources in the resource library, thus obtaining site planning information. 3D modeling software enables manufacturing departments to design the entire production process for digital products, providing virtual demonstrations before deploying any actual materials and machines. This allows companies to increase opportunities for collaboration, reuse, and collective innovation throughout the product lifecycle. The Plant Layout module is a module within 3D modeling software used for factory layout design and maintenance, outputting a model of the workshop layout.

[0059] S102, Based on the site planning information, perform three-dimensional modeling of the hull to obtain a three-dimensional model of the hull.

[0060] A 3D model of a ship's hull can be a three-dimensional model of the ship's hull generated using 3D modeling software. 3D models can more realistically represent the overall structure of the ship's hull and are closer to the actual ship.

[0061] 3D modeling is the process of creating a spatial model of a ship's hull using 3D modeling software. Using 3D modeling makes the modeling reference more intuitive, greatly improving the speed of workshop modeling and layout.

[0062] S103, determine the target tooling based on the tooling information.

[0063] Identifying a target tooling part can be done using 3D modeling software by searching for the corresponding tooling part based on its number. Specifically, a separate database table storing the user-designed tooling parts can contain information such as tooling part number, name, dimensions, and appearance. Since each tooling part has a unique number, this number serves as a unique identifier for finding the tooling part. To retrieve the target tooling part, simply enter its number. Alternatively, the system's built-in process component library can be used; each tooling part has a corresponding number, and entering the system-defined tooling part number will retrieve the target tooling part.

[0064] Based on the above embodiments, optionally, determining the target tooling based on the tooling information includes:

[0065] Read the coordinate information of each tooling component in any two horizontal cross-sections from the tooling component information;

[0066] If any two tooling components have the same coordinate information for any two horizontal cross-sections, then they are identified as the target tooling component.

[0067] In this solution, the coordinate information can be the set of coordinates of all points on a horizontal cross-section of the tooling, forming the coordinates of that plane. Obtaining the coordinate information of any two horizontal cross-sections is to determine if the tooling conforms to specifications. If it does, the system can automatically import and place it into the 3D model based on the 2D view. If it does not conform, manual intervention is required to place the tooling into the 3D model according to certain rules. For example, non-conformity could be due to an irregular shape. While tooling is typically a regular cylinder, cuboid, or shape that is wider at the bottom and narrower at the top, irregular tooling might be narrower at the bottom and wider at the top. In this case, automatic placement of irregular tooling by the system might cause collapse if tooling is stacked.

[0068] Reading can refer to the process where the Plant layout module automatically cuts a tooling part horizontally, displays the coordinates of each point on the plane, and presents it in a 2D view. This 2D view provides information such as the plane's dimensions and shape, facilitating comparison with other horizontal cut surfaces.

[0069] Determining a target tooling part involves comparing the coordinate information of any two horizontal cross-sections to determine if the tooling part conforms to specifications. Since a single tooling part can be divided into numerous planes, obtaining the coordinate information of these planes reveals the tooling part's shape and dimensions. The Plant layout module automatically combines this coordinate information to determine if the tooling part conforms to specifications. If the coordinate information of two horizontal cross-sections is completely consistent, the tooling part is considered to have a regular shape and conform to specifications, allowing for appropriate placement based on the 2D view.

[0070] In this solution, by reading the horizontal cross-sectional coordinates of the tooling, it can automatically determine whether the tooling is a regular shape and conforms to the placement specifications. If it conforms, the system automatically places the tooling; otherwise, manual intervention is required. This improves the efficiency of subsequent tooling placement based on the 2D view to a certain extent, and the notification of manual intervention to modify the tooling when it does not conform to the specifications avoids the problem of rework due to errors after placement, saving time in the thin plate production line workshop modeling and improving the efficiency of thin plate production line workshop modeling.

[0071] S104, import the tooling deployment information into the hull 3D model, and display the outline of the target tooling in the tooling deployment information.

[0072] In mechanical drawing, when the axis of a solid of revolution is parallel to the projection plane, the dividing line that separates the visible and invisible parts of the solid's rotating surfaces relative to that projection plane is called the line of revolution, and the projection of this line of revolution onto the projection plane is called the contour line. In this design, the contour line can be the external lines of the target tooling part.

[0073] Importing tooling deployment information can be the process of placing tooling deployment information into the 3D model of the ship's hull in 3D modeling software. Specifically, it can be the process of importing the plan layout information into the 3D model through the Plant layout module, or it can be the process of retrieving the target tooling from the resource library and then placing it into the 3D model.

[0074] The process of displaying the outline of target tooling components can be the conversion of a two-dimensional cross-section of a workshop's steel frame columns into outlines, providing the user with information on the outlines, positions, and quantities of each target tooling component. Alternatively, this can be done through the Plant layout module.

[0075] Based on the above embodiments, optionally, the tooling deployment information is imported into the hull 3D model, and the outline of the target tooling in the tooling deployment information is displayed, including:

[0076] Generate a two-dimensional view of the tooling based on the tooling deployment information;

[0077] Based on the determined target tooling, determine the outline of the target tooling in the two-dimensional view of the tooling;

[0078] Import the two-dimensional view of the tooling into the three-dimensional model of the hull, wherein the three-dimensional model of the hull and the two-dimensional view of the tooling have the same coordinate system.

[0079] In this solution, the two-dimensional view of the tooling can be a plan view of the tooling deployment in the thin plate production line workshop. The plan view can include information such as the tooling to be placed, the quantity of tooling, and the placement position. The placement position can be represented by absolute coordinates, in the format A(X, Y). Specifically, it can also be generated in the Plant layout module.

[0080] Coordinates can be a set of ordered data selected according to a prescribed method to determine the position of a point in space. Using the same coordinate system for the 3D hull model and the 2D view of the tooling can be a unified coordinate representation method used to determine the position of the tooling when placing the 2D view of the tooling in the 3D model. The purpose of using the same coordinate system is to ensure that the final constructed hull model is consistent with the pre-designed drawing. If the same coordinate system is not used, the coordinate length of each grid on the coordinate axis may be inconsistent, resulting in inconsistent placement of the tooling in the final design. For example, if the coordinate length of each grid in the 2D view of the tooling is limited to 2 meters, while the coordinate length of each grid in the hull model is 4 meters, and a tooling has coordinates (2, 0) in the 2D view, it is located 4 meters from the center point. If the same coordinate system is not used, and the coordinates are (2, 0) in the 3D model, it means that the tooling is located 8 meters from the center point.

[0081] Generation can be the process by which a user draws a two-dimensional view of a tooling component using tooling deployment information in the Plant layout module, that is, the process of obtaining a two-dimensional view of a boss after drawing a sketch.

[0082] Determining the outline can be done by finding the target tooling in a separate database table or the system's built-in process component library after the user has designed the tooling, and then drawing the outline of the target tooling based on its dimensions and appearance. Specifically, the outline can be automatically determined through the Plant layout module, or it can be drawn manually by the user. Automatic determination is suitable for simpler outlines, while manual determination is suitable for more complex outlines.

[0083] Importing can be the process of using the plant layout module to place a 2D view of a tooling component into a 3D model of the ship's hull. Specifically, once the 2D view of the tooling component is designed, it can be stored in the database of 2D views in the 3D design software. When importing the 2D view of the tooling component into the 3D model of the ship's hull, the corresponding 2D view can be imported by searching for its filename.

[0084] In this solution, by setting up a method to import a 3D model from a 2D view, the coordinate systems of the 2D view and the 3D model are unified, making 2D drawings and 3D modeling environments compatible, shortening workshop modeling time and improving modeling efficiency.

[0085] S105, construct a model entity for the target tooling based on the outline.

[0086] A model entity can be a three-dimensional triangular mesh. Typically, a solid model is defined by connecting three data points identified by a triangle with a set of lines connecting them in different planes. The model entity is the foundation for building a three-dimensional model. In this scheme, the model entity can represent all the shape information of the target tooling part.

[0087] Building can be the process of filling the area constructed by the outline of the target tooling in the Plant layout module to obtain the model entity of the target tooling. The built model entity will be fed back to the user through the client so that the user can edit the model entity later.

[0088] Based on the above embodiments, optionally, constructing a model entity for the target tooling based on the contour lines includes:

[0089] Read the height information of the target tooling from the tooling information;

[0090] Based on the outline and the height information, a model entity is constructed for the target tooling.

[0091] In this solution, the height information can be the height of the target tooling, specifically expressed in meters. For example, the crane height is 15.5 meters, and the forklift height is 3.5 meters.

[0092] Reading can be the process of finding the corresponding dimension information of a tooling in a database table that stores tooling information after the target tooling has been determined. The dimension information includes height information.

[0093] The construction process can be described as follows: after determining the target tooling and its height information, select the outline of the model to be generated and directly stretch it to generate the model entity. Since the shape of the target tooling is determined to be a regular shape in advance, the outline can be stretched directly, eliminating the need for manual filling in the previous steps.

[0094] In this solution, the method of constructing the model entity by setting the outline is eliminated, thus eliminating the need to redraw the previous two-dimensional sketch, making the modeling process simpler and improving the efficiency of modeling to a certain extent.

[0095] Based on the above embodiments, optionally, after constructing a model entity of the target tooling based on the contour lines, the method further includes:

[0096] A workshop resource library is created for the three-dimensional model of the ship hull and the model entities of the target tooling;

[0097] In response to a tooling data retrieval operation from the resource library, a tooling to be edited is generated and displayed; wherein, the model entity of the tooling to be edited is hot-associated with the tooling data of the tooling to be edited in the workshop resource library.

[0098] In this solution, the workshop resource library can be a database that stores tooling model entities, factory buildings, roads, etc. When it is necessary to build a 3D model of the ship hull, this workshop resource library can be called to find the corresponding tooling model entities and place them in the 3D model.

[0099] The tooling to be edited can be a tooling selected in the workshop resource library. When this tooling is placed in the 3D model, operations such as changing the quantity and changing the position can be performed.

[0100] Creating a workshop resource library can be a process of establishing a workshop resource library based on the layout plan, tooling drawings, and list of materials for the thin plate production line workshop. Alternatively, it can be created through the Plant layout module.

[0101] The tooling data retrieval operation can be the process of searching for the corresponding tooling in a database table that stores tooling information and then placing the corresponding tooling into a 3D model. Specifically, tooling can be retrieved by searching for the tooling name or tooling number, etc. After a successful search, the target tooling is placed into the 3D model.

[0102] Thermal correlation means that when a tooling part is imported into a 3D model and edited, the corresponding tooling part data in the workshop resource library will also be updated accordingly. For example, when a crane resource is imported into a 3D model and the crane is moved, the coordinate position will change, so the coordinates of the corresponding crane in the workshop resource library will be updated in real time.

[0103] In this solution, by creating a workshop resource library and hot-linking the model entity of the tooling to be edited with its data in the library, the required tooling can be quickly retrieved. Furthermore, the corresponding tooling data in the workshop resource library can be updated in real time after changes to the tooling data, facilitating future retrieval. Utilizing model database technology to build a model library for tooling such as jigs and equipment significantly reduces workshop modeling time and improves modeling efficiency.

[0104] Based on the above embodiments, optionally, in response to operation instructions on the model entity, generating hull manufacturing modeling results includes:

[0105] In response to an array operation command, mirror operation command, or alignment operation command for the model entity, perform array operation, mirror operation, or alignment operation on the model entity;

[0106] The ship manufacturing modeling results are generated based on the results of array operations, mirror operations, or alignment operations.

[0107] In this scheme, the array operation command can be an operation command that arranges the model entities after selecting the model entities to be arrayed, selecting the quantity, spacing and direction.

[0108] The mirror operation command is an operation command that, after selecting the model entity to be mirrored and the mirror surface, uses the mirror tool to copy a model entity that is arranged in the opposite direction but completely identical in all other aspects.

[0109] Alignment commands can be commands that involve selecting the model entities to be aligned, choosing the alignment method, and then arranging the model entities using the alignment tool.

[0110] The response can be the process by which array tools, mirror tools, and alignment tools execute array operation commands, mirror operation commands, and alignment operation commands.

[0111] Generating ship hull manufacturing modeling results can be achieved by editing the individual model entities in a 3D model to ultimately achieve the effect of 2D drawings.

[0112] In this solution, by using array tools, mirror tools, and alignment tools to execute corresponding array operation commands, mirror operation commands, and alignment operation commands, the quantity, position, and arrangement of each model entity can be quickly changed, so as to quickly create a 3D model of the thin plate production line workshop and improve modeling efficiency.

[0113] S106, in response to the operation command on the model entity, generate the hull manufacturing modeling result.

[0114] Operation commands can be instructions sent by the user when editing the target tooling. The user can edit the target tooling by increasing the number of target tooling or moving the target tooling. The purpose is to make the final hull manufacturing modeling result conform to the layout of the hull plan.

[0115] The hull manufacturing modeling result can be the final hull model obtained by performing 3D modeling of the hull in the Plant layout module, importing tooling deployment information, and editing the tooling model entities.

[0116] Based on the above embodiments, optionally, after generating the hull manufacturing modeling results, the method further includes:

[0117] Static and / or dynamic simulations are performed on the hull manufacturing modeling results to determine correction information for the generated hull manufacturing modeling results, so as to provide model anomaly alerts.

[0118] In this solution, static simulation can be used to check whether the various model entities in the final 3D model of the thin plate production line workshop conform to the placement specifications. For example, if there are five horizontally placed containers in the 3D model of the thin plate production line workshop, static simulation can be used to check whether the containers overlap. If overlap exists, it needs to be modified accordingly; if there is no overlap and all containers are on the same horizontal plane with equal spacing, then it is considered to conform to the placement specifications.

[0119] Dynamic simulation can be used to check whether the entities in the final 3D model of the thin plate production line workshop conform to the placement specifications by dynamically rotating or moving the physical models. For example, if there are three cranes placed horizontally in the 3D model of the thin plate production line workshop, and the cranes rotate during operation, dynamic simulation can be used to recreate the crane operation process and check whether there are any collisions or other phenomena that affect the operation of the other cranes when the three cranes are running simultaneously. If the dynamic simulation finds that no such phenomena occur, then the entities in the 3D model of the thin plate production line workshop are considered to conform to the placement specifications.

[0120] Correction information can be specific error messages displayed when static or dynamic simulations reveal that the placement of model entities does not conform to specifications. Specifically, this information can include the specific error type and the coordinates of the model entity where the error occurred, expressed as: Specific Error Type - Coordinates of the Model Entity Where the Error Occurred. For example, a dynamic simulation might reveal that two cranes collide during rotation. The crane boom is 10 meters long, crane 1 has coordinates (10, 0), and crane 2 has coordinates (15, 0). This correction information could be expressed as: Crane boom collision during rotation - Crane 1 (10, 0), Crane 2 (15, 0).

[0121] Model anomaly alerts can be provided when static or dynamic simulations reveal that the placement of model entities does not conform to specifications. In such cases, the corrective information is fed back to the client through the Plant layout module, allowing the user to modify the ship manufacturing modeling results.

[0122] This solution utilizes both static and dynamic simulations to identify problems in the hull manufacturing modeling results before production. These problems are then addressed to generate accurate hull manufacturing models. This avoids the rework caused by discovering errors only during actual production, thus reducing production costs and improving modeling efficiency to some extent.

[0123] In this embodiment, site planning information, tooling information, and tooling deployment information of the hull are obtained; based on the site planning information, a 3D model of the hull is obtained; a target tooling is determined based on the tooling information; the tooling deployment information is imported into the 3D model of the hull, and the outline of the target tooling in the tooling deployment information is displayed; a model entity is constructed for the target tooling based on the outline; and a hull manufacturing modeling result is generated in response to operation commands on the model entity.
