Description

Technical Field

[0001] The present disclosure relates to the technical field of ship painting design, and in particular to a method, system, electronic equipment and medium for calculating the painting area of ​​a ship. Background Art

[0002] The ship coating design work is not only related to the service life, maintenance cycle, operating cost, construction cycle and cost of the ship, but also because the coating quality has a huge impact on the safety of ship operation, the coating design work has attracted more and more attention.

[0003] Major domestic shipyards and design institutes usually use TRIBON software (an integrated system specially used for shipbuilding, which combines computer-aided design (CAD) and computer-aided manufacturing (CAM) functions, including: hull structure, marine engineering, electrical power, painting and other ship design disciplines. It is one of the mainstream design software in China's current shipbuilding industry) to complete the precise painting area extraction based on the three-dimensional model.

Users can use this module to complete: (1) statistical range definition, (2) area calculation of parts within a region, and (3) area calculation of a single part. Flat panels, curved panels, and profiles can all correctly extract model surfaces. However, in addition to statistical part area, the Design Manager module does not provide more functions for ship coating design.

[0044] Example 1

[0045] This embodiment provides a method for calculating the coating area of ​​a ship, see Figure 1 , the calculation methods of the coating area of ​​ships include:

[0046] S1. Filter out the semantics corresponding to the structure to be painted.

[0047] In an optional embodiment, step S1 includes:

[0048] S11. The semantics corresponding to the structure to be painted are filtered out through the directory tree function of Smart3D (a real-life modeling software that can convert photos and laser scanning data into accurate three-dimensional models).

[0049] In an optional embodiment, the semantics include an object-modification semantics and at least one modification-only semantics.

[0050] In an optional embodiment, the semantic type containing object modification includes at least one of: in a cabin, a special structure, a cabin and a special structure, and a user-defined structure.

[0051] In an optional embodiment, only the modified semantic types include top surface, bottom surface, enclosing surface, inner surface, outer surface, upper surface, lower surface, insulation coverage area, dressing coverage area, marking coverage area, multi-compartment intersection painting area, multi-compartment complement painting area, airtight area, wind and raintight area, oil-tight area, watertight area and at least one of user-defined areas.

[0052] S2. Determine the calculation rules corresponding to the semantics.

[0053] In an optional implementation, the calculation rules include Smart3D calculation rules, custom calculation rules, or Smart3D calculation rules and custom calculation rules.

[0054] S3. Calculate the coating area of ​​the structure to be coated according to the calculation rules.

[0055] This embodiment analyzes the structure to be painted by semantics, automatically disassembles the structure to be painted, simplifies the complexity of the calculation of the structure to be painted, and realizes the rapid estimation of the painting area of ​​the structure to be painted based on the automatic calculation rules, thereby improving the efficiency and quality of ship painting design. In addition, it can also shorten the product production cycle, which is beneficial to the cost control and planning management of ship construction.

[0056] A specific example is introduced below to describe in detail the method for calculating the coating area of ​​a ship of this embodiment.

[0057] like Figure 2a-2j Taking the container ship painting calculation as an example, it can be seen that ships have their own characteristic areas and painting requirements, so the painting calculation is very complicated.

[0058] This example divides the calculation method of the ship's coating area into three levels: semantic analysis layer, process definition layer, and calculation layer.

[0059] The semantic analysis layer will correspond various coating calculation rules to multiple semantic combinations.

[0060] Specifically:

[0061] Through semantic analysis, Figure 2a-2j The "painting project" is simplified to a partial combination of a semantic filter of "including object modification" and one (or more) semantic filters of "only modification".

[0062] The semantics of "with object modification" refers to the semantics of containing explicitly modified objects. Specifically, explicitly modified objects refer to ship structures specifically specified in the coating technical specification, such as superstructures, compass decks and other ship structures. The semantic types of "with object modification" include: (1) in the cabin (referring to a large area, that is, a collection of multiple cabins); (2) special structures, such as: rudders, rudder poles, wind ducts and other special-shaped structures; (3) the combination of cabins and special structures; (4) user-defined structures, which in this example refers to the part structure of a certain large area in the "Hull Paint Matching Table" that does not clearly specify the coating method.

[0063] The semantics of "modification only" refers to the semantics of modification that does not contain or clearly specifies an object. The semantics of not clearly specifying an object include the inner area or deck of the seabed door. Since the inner area or deck of the seabed door is not unique to the entire ship, it is not clearly specified. Modifications in this case are considered "modification only". The semantic types of “modification only” include: (1) top surface, which only includes the inner surface area of ​​the top plate in the closed space; (2) bottom surface, which only includes the bottom surface area of ​​the top plate in the closed space; (3) enclosure surface, which only includes the inner surface area of ​​the enclosure plate in the closed space; (4) inner surface, which includes the inner surface area of ​​the top plate, bottom plate and enclosure plate in the closed space; (5) outer surface, which includes the outer surface area of ​​the top plate, bottom plate and enclosure plate in the closed space; (6) upper surface, which only includes the upper surface area of ​​the part; (7) lower surface, which only includes the lower surface area of ​​the part; (8) insulation, dressing and marking, which includes the area covered on the surface of the part by insulation, dressing and marking; (9) intersection of multiple compartments (or large areas), which includes the sum of the coating area of ​​the parts in the intersection of multiple compartments (or large areas); (10) complement of multiple compartments (or large areas), which includes the sum of the coating area of ​​the parts in the complement of multiple compartments (or large areas); (11) tightness, which includes air tightness, wind and rain tightness, oil tightness and water tightness. (12) User-defined areas, such as below the waterline of the ship, within four meters of the sulfide drainage pipe, and other user-defined areas.

[0064] For example, if the selection is made into a combination of "Including object modification (1) In the cabin", "Modification only (1) Top surface" and "Modification only (8) Insulation and marking", it can be determined that the structure to be painted is the area of ​​the top plate in a cabin (or large area) covered by insulation (or dressing or marking).

[0065] The process definition layer determines which parts of the structure to be painted need to be calculated based on the semantic combination, and clearly gives the calculation process of the parts.

[0066] Specifically:

[0067] The process definition layer mainly converts the general semantic modification selection into more detailed coating area calculation rules, including which parts are involved in the calculation and how the calculation process works. The process definition layer includes: modeling large areas, calculation rules corresponding to the "with object modification" semantic type, and calculation rules corresponding to the "only modification" semantic type.

[0068] The large modeling area refers to the model area that is divided for the needs of three-dimensional modeling, and is distinguished from each other by the Smart3D system directory tree. The large modeling area has great programming convenience. The part range of the large modeling area partially overlaps with the large area specified in the "Hull Paint Matching Table", which means that the part range of the large modeling area is greater than or equal to the large area specified in the "Hull Paint Matching Table". Among them, the tail, engine room, cargo hold, bow, and outer plate, the large modeling area and the "Hull Paint Matching Table" are almost equal, and the upper building modeling area and the "Hull Paint Matching Table" are inclusive. The open deck is part of the tail, engine room, cargo hold, and bow. In addition, this partitioning method is almost applicable to current mainstream commercial ship types. Therefore, the large modeling area can replace the large area concept of the semantic analysis layer. The large area refers to the large area that cannot be defined by the directory tree but can only be defined by the space body. The large modeling area uses the Smart3D directory tree function to filter parts.

[0069] The calculation process for modeling a large area is to obtain all structural parts under the current directory tree as painting calculation objects, and take the double-sided area as the painting calculation area.

[0070] The calculation rules corresponding to the "with object modification" semantic type and the calculation rules corresponding to the "only modification" semantic type include:

[0071] (1) Calculation rules within a cabin (or large area)

[0072] A cabin (or large area) is a kind of spatial range. Therefore, the calculation parts of the structure to be painted are screened by spatial range, including three basic cases and their partial combinations.

[0073] The basic calculation process is as follows:

[0074] Case 1: If the plate plane is the same as the plane of the cabin (or large area) boundary and falls within the cabin (or large area) boundary, the single-sided area of ​​the plate part is taken as the calculated coating area.

[0075] Case 2: If the plate intersects with the boundary plane of the cabin (or large area), the area of ​​the included part of the plate part is taken as the calculation area for painting.

[0076] Case 3: If the plate is completely contained within the boundary plane of the cabin (or large area), the area of ​​the plate part is taken as the calculation area for coating.

[0077] (2) Calculation rules for special structures

[0078] Special structures select parts by accurate structural names, such as: open-air main deck, compass deck, etc. rather than general structures, such as decks.

[0079] Calculation process: Filter out all parts with the same name as the specified structure from the database, and take the area of ​​these parts as the coating area.

[0080] (3) Calculation rules for user-defined structures

[0081] All parts within the user-defined structure area that have not yet participated in the painting calculation. This modification is only performed after other modification calculations in the area are completed.

[0082] Calculation process: Calculate the area of ​​all parts in the designated large modeling area, cabin (or large area), or special structure, and then subtract the calculated painting area of ​​the designated large modeling area, cabin (or large area), or special structure in the "Hull Paint Matching Table" to obtain the remaining painting area of ​​the designated large modeling area, cabin (or large area), or special structure.

[0083] (4) Calculation rules for top surface

[0084] The plane is the same as the plane of the top boundary of the cabin (or large area), and the single-sided area of ​​the plate part falls within the boundary of the cabin (or large area). This modification must be combined with "Special structure with object modification (2)".

[0085] Calculation process: Get the parts in "Basic case 1: If the plate plane is the same as the plane of the cabin (or large area) boundary and falls within the cabin (or large area) boundary, then take the single-sided area of ​​the plate part as the coating calculation area" in "Special structure with object modification (2)", find the parts with overlapping top boundaries in "Special structure with object modification (2)", and take the single-sided area of ​​these parts as the coating area.

[0086] (5) Calculation rules for the bottom surface

[0087] The plane is the same as the plane of the top boundary of the cabin (or large area), and the single-sided area of ​​the plate part falls within the boundary of the cabin (or large area). This modification must be combined with "Special structure with object modification (2)".

[0088] Calculation process: Get the parts of "Basic case 1: If the plate plane is the same as the plane of the cabin (or large area) boundary and falls within the cabin (or large area) boundary, then take the single-sided area of ​​the plate part as the coating calculation area" in "Special structure with object modification (2)", find the parts with overlapping bottom boundaries in "Special structure with object modification (2)", and take the single-sided area of ​​these parts as the coating area.

[0089] (6) Calculation rules for enclosed surface

[0090] The plane is the same as the plane of a certain enclosure boundary of the cabin (or large area), and the single-sided area of ​​the plate part falls within the cabin (or large area) boundary. This modification must be combined with "Special structure with object modification (2)".

[0091] Calculation process: Get the parts of "Basic case 1: If the plate plane is the same as the plane of the cabin (or large area) boundary and falls within the cabin (or large area) boundary, then take the single-sided area of ​​the plate part as the coating calculation area" in "Special structure with object modification (2)", find the parts with overlapping enclosing boundaries in "Special structure with object modification (2)", and take the single-sided area of ​​these parts as the coating area.

[0092] (7) Calculation rules for inner surface

[0093] The plane is the same as the plane of the cabin (or large area) boundary, and it is the single-sided area of ​​the plate part that falls within the cabin (or large area) boundary; this modification must be combined with "Special structure with object modification (2)".

[0094] Calculation process: Similar to the calculation process of the bottom surface and enclosing surface.

[0095] (8) Calculation rules for external surface

[0096] The calculation rules are the same as those for the inner surface. Since the coating area calculation is quantitative and the plate thickness has little effect on the calculation result, there is no need to distinguish between the inside and the outside.

[0097] (9) Calculation rules for the upper surface

[0098] The single-sided coating area of ​​a part. This modification must be combined with "Including object modification (3) Combination of cabin and special structure".

[0099] Calculation process: Obtain parts that meet the conditions of "including object modification (3) combination of cabin and special structure" and take the single-side area of ​​the part as the coating area.

[0100] (10) Calculation rules for the lower surface

[0101] Same as above surface. Since the coating area calculation is quantitative and the plate thickness has little effect on the calculation result, there is no need to distinguish between inside and outside.

[0102] (11) Calculation rules for absolute compensation

[0103] The area of ​​a part covered by insulation, dressing, or marking. Insulation, dressing, and marking can all be presented in the form of spatial bodies in 3D design software.

[0104] Calculation process: Take the part designated "with object modification" and take the area covered by insulation, dressing, and marking as the coating area.

[0105] (12) Calculation rules for intersection of multiple compartments (or large areas)

[0106] The part screening range defined by the intersection of multiple compartments (or large areas) includes three cases:

[0107] Case 1: The plane is the same as the plane of the cabin (or large area) boundary, and the single-sided area of ​​the plate parts falls within the cabin (or large area) boundary;

[0108] Case 2: Partially included in the area of ​​the plate parts within the boundary plane of the cabin (or large area);

[0109] Case 3: The area of ​​the plate parts is completely contained in the boundary plane of the cabin (or large area).

[0110] (13) Calculation rules for complement sets of multiple compartments (large or regional)

[0111] The part screening range defined by the complementary area of ​​multiple compartments (or large areas) includes three cases:

[0112] Case 1: The plane is the same as the plane of the cabin (or large area) boundary, and the single-sided area of ​​the plate parts falls within the cabin (or large area) boundary;

[0113] Case 2: Partially included in the area of ​​the plate parts within the boundary plane of the cabin (or large area);

[0114] Case 3: The area of ​​the plate parts is completely contained in the boundary plane of the cabin (or large area).

[0115] (14) Calculation rules for confidentiality

[0116] Attributes include watertight, airtight, oiltight, and weathertight parts.

[0117] Calculation process: Take all parts with specified tightness in the large modeling area or cabin (or large area). The area of ​​these parts is used as the painting calculation area.

[0118] (15) Calculation rules within user-defined areas

[0119] This is achieved through Samart3D space bodies. This type of custom space body is not unique. For example: the drainage ditch area, or the inner range of the seabed door, or within a certain range of the sewage pipe, or above the freeboard.

[0120] The calculation process is similar to taking the intersection of multiple compartments (or large areas).

[0121] The calculation implementation layer performs logical calculations and area numerical calculations based on the process definition results.

[0122] Specifically:

[0123] This layer converts the calculation logic of the coating area of ​​each semantic into a specific algorithm, and gives the Smart3D implementation interface and some key logic of these algorithms.

[0124] Figure 3 A mapping diagram between semantics and algorithms.

[0125] The following is a brief introduction to the implementation of each algorithm in Smart3D:

[0126] (1) Implementation of retrieving the system directory tree: Use the GetSystem Children (interface) of the System Folder (a folder used to store system files and configuration information in the operating system) object of Ingr.SP3D.Common.Middle (a programming-related namespace) to recursively obtain all parts under the specified folder.

[0127] (2) Implementation of normal vector isotropic determination:

[0128] 1. Use Smart3D to provide matrix dot multiplication to obtain the cosine values ​​of the two normal vectors Vector1.Dot(Vector2) (the dot product (or inner product) operation of two vectors);

[0129] 2. Use the inverse cosine function to find the angle between the two vectors and determine whether the two normal vectors are in the same or opposite directions.

[0130] (3) Implementation of intersection determination between part space and space body, and between space bodies: Use the Intersects method of the RangeBox object (a class that describes the geographical range of a spatial object) of Ingr.SP3D.Common.Middle to determine whether they intersect.

[0131] (4) Implementation of inclusion judgment between part space and space body, and between space bodies: Use the Contains method of the RangeBox object of Ingr.SP3D.Common.Middle to determine whether they intersect.

[0132] (5) Implementation of classification and naming judgment, part area and tightness judgment: Use the GetProperty Value (interface) of the Business Object object (representing the business object) of Ingr.SP3D.Common.Middle to obtain relevant properties.

[0133] (6) Implementation of distance determination from part (WC) to any boundary surface:

[0134] 1. Use Get Property Value to obtain the coordinates of the center of gravity (obtain the XYZ values ​​three times);

[0135] 2. Use Get DistanceBetween (a function or method for obtaining the distance between two points, objects, or positions) of the RangeBox object of Ingr.SP3D.Common.Middle to obtain the distance.

[0136] (7) Calculate the single-side area of ​​the cross-section parts:

[0137] 1. Use the Intersect method of the RangeBox object of Ingr.SP3D.Common.Middle to obtain the intersection space body.

[0138] 2. Get the normal vector of the part base surface.

[0139] 3. Find the face with the smallest angle with the normal vector of the base surface of the part among the faces of the intersecting spatial body. The area of ​​this face is the area of ​​the intersecting part.

[0140] (8) Implementation of upper surface area estimation: Half of the part area is the single-side area.
