[0027] Embodiment 1

[0028] This embodiment provides a method for marking installation information of ship outer outfitting, including:

[0029] Setting marking rules and marking symbols for ship external outfitting installation information; the ship external outfitting installation information includes installation part number information, installation part positioning information and / or installation part installation process information;

[0030] According to the marking rules of the ship's outer outfitting installation information and the installation part model data, the installation part number information, the installation part positioning information and / or the installation part installation process information are marked on the three-dimensional model of the ship.

[0031] The following will describe in detail the marking method of ship outer outfitting installation information provided by this embodiment in conjunction with the diagram. Figure 1 , which is a flow chart of a method for marking ship outer outfitting installation information in one embodiment. Figure 1 As shown, the method for marking the installation information of the ship's outer outfitting specifically includes the following steps:

[0032] S11, setting the marking rules and marking symbols for the ship's external outfitting installation information. In this embodiment, the ship's external outfitting installation information includes installation part number information, installation part positioning information and / or installation part installation process information. Installation part number information is divided into material name, segment number, and part number information. Installation part positioning information is divided into specific installation positioning information of parts and components, which can be concisely expressed in the form of size, text, etc. Installation part installation process information is divided into welding information, painting information, and process requirements.

[0033] In this embodiment, the marking rules of the ship's outer outfitting installation information require that the basic information of the installation parts shall be marked with a unified identification character code for text marking, that the positioning information of the installation parts shall be based on the characteristic structure and modeling method of each installation part, and the marking principles of the installation information of the same type of installation parts shall be sorted out, and that the installation process information of the installation parts shall be based on the welding process requirements (including weld angle height, welding type, etc.) to determine the welding process symbols corresponding to different process requirements, and the painting process information shall be based on the paint type to determine the one-to-one relationship between the paint brand and the display color. When marking the process requirements, the process designer shall define the process requirements in advance in the form of model parameters, and the process information shall be marked directly based on the specific parameter information.

[0034] S12, configuring the global coordinate system of ship design based on the ship type rib position parameters, constructing the ship type rib position plane information on the ship design global coordinate system, searching the spatial range corresponding to any node model in the product structure tree of the ship, constructing the ship type rib position plane features within the spatial range corresponding to the node model, and labeling the constructed ship type rib position plane features with the corresponding ship type rib position names.

[0035] Specifically, in S12, the ship design global coordinate system is configured based on the ship type rib position parameters, and the step of constructing rib position plane information on the ship design global coordinate system also includes: determining the center coordinates of each rib position plane in the X, Y, and Z axis directions of the ship design global coordinate system to construct the ship type rib position plane information based on the center coordinates of each rib position plane.

[0036] For example, the spacing between ribs in the longitudinal and transverse directions of the ship design, the distance between the mid-ship surfaces, etc.; the directions of each axis system and the coordinate origin of the global coordinate system of the ship design must be consistent with the ship type parameter information.

[0037] The X-axis direction of the ship design global coordinate system is from the stern to the bow;

[0038] The Y-axis direction of the ship design global coordinate system is from starboard to port;

[0039] The Z-axis direction of the ship design global coordinate system is the height direction of the ship deck;

[0040] The coordinate origin of the ship design global coordinate system is the starting position point of the ship type parameters.

[0041] For example, in the X direction, the rib plane FR1 is 1000 mm away from the coordinate origin. Then, in the global coordinate system of ship design, the coordinates of the midpoint of the rib plane are determined to be FR1 (1000 mm, 0, 0), and the rib plane is constructed according to the obtained coordinates of the rib plane origin.

[0042] In S12, the spatial range corresponding to any node model (any node model is a sub-node object of a specified type, and the sub-node object of the specified type is a sub-level of the currently selected node, and the obtained node of the specified type is included in the selected node level and also in the product structure tree level) in the product structure tree of the ship is searched, and the step of constructing the rib position plane feature within the spatial range corresponding to the node model also includes: traversing the spatial range of each node model, and superimposing the obtained spatial range in turn to obtain the calculated maximum spatial range value and the minimum spatial range value to form the superimposed spatial range. Due to the wide distribution range of the installation parts in the whole ship area, there are two situations in the node selection process of the rib position information of the outer outfitting ship type: Scenario 1: The current installation parts are arranged with a small distribution range, and the larger node of the outer outfitting installation parts can be selected; Scenario 2: The current installation parts are arranged with a wide distribution range, and the maximum and minimum structural boundary part objects in the installation parts background model can be selected.

[0043] Specifically, the spatial range of the node model is generally represented as the smallest enclosing shell, and there are generally two ways to obtain it: 1. directly obtain it through the API provided by the current design software; 2. obtain the nearest and farthest points from the origin of the design coordinate system by parsing the characteristics of the entity model set; the nearest and farthest points can form a rectangular enclosing shell.

[0044] Superposition of the acquired spatial range refers to repeated spatial range calculation for several current bounding shells.

[0045] For example, three spatial ranges are currently known: Box1[Min1(0, 0, 0), Max1(3, 3, 3)], Box2[Min2(2, 2, 2), Max2(5, 5, 5)], and Box3[Min3(-1, -2, -3), Max3(1, 2, 3)]; first, the spatial ranges of Box1 and Box2 are calculated, and the result is BoxA[MinA(0, 0, 0), MaxA(5, 5, 5)], then the spatial ranges of BoxA and Box3 are calculated, and the structure obtained is BoxB[MinB(-1, -2, -3), MaxB(5, 5, 5)], and the final spatial range after superposition calculation is BoxB.

[0046] The step of constructing a ship type rib position plane feature within the spatial range corresponding to the node model in S12, and labeling the constructed ship type rib position plane feature with the corresponding rib position name also includes: selecting a ship type rib position plane within the superimposed spatial range according to the ship type rib position parameters and the superimposed spatial range, constructing a ship type rib position plane feature within the spatial range, and labeling the corresponding ship type rib position name on the constructed ship type rib position plane feature. In this embodiment, the ship type rib position planes selected within the spatial range include FR, Long, and Deck ship type rib position plane information.

[0047] S13, marking the installation part number information, the installation part positioning information and / or the installation process information of the installation part on the three-dimensional model of the ship according to the marking rules of the ship's outer outfitting installation information and the installation part model data.

[0048] The S13 specifically includes the following steps:

[0049] Based on the model data of the installation parts and the actual construction status of the current section / area / block of the ship, the installation parts number information is marked;

[0050] Matching the installation part model data with the installation background model, and marking the installation part positioning information on the three-dimensional model of the ship in combination with the installation background model;

[0051] The installation part model data is matched with the installation background model, and the installation process information of the installation part is annotated on the three-dimensional model of the ship in combination with the installation background model.

[0052] In this application, during the process of creating installation annotations, there is no correlation or order between the annotation of the installation part number information, the annotation of the installation part positioning information, and the annotation of the installation part installation process information. The appropriate installation annotation order can be selected according to the actual installation annotation scenario.

[0053] Specifically, the step of marking the installation part number information based on the installation part model data and the actual construction status of the current section / area / block of the ship includes:

[0054] First, select any outfitting installation part node in the product structure tree of the ship;

[0055] Next, the product selection structure tree nodes are traversed, and the outfitting installation part nodes are screened according to the node screening conditions to obtain the installation parts that meet the requirements. In this embodiment, the screening conditions include information such as specific node types and specific attribute values.

[0056] Then, the construction information generated in the current actual construction process is obtained according to the section and area where the outfitting installation part is located. In this embodiment, the construction information includes the construction status and the installation viewing angle.

[0057] Among them, construction status: Since in the actual construction, for the segments with curved outer plates, there is an external field turning situation (rotating 180 degrees along the center line or rotating based on the change of the linear ratio of the outer plate), the construction status is divided into: normal state, reverse state, and lying state.

[0058] Installation viewing angle: Due to the wide distribution range of the installation parts, the installation viewing angle is divided into: top view, top view, bow, stern, port side, and starboard side.

[0059] Then, based on the installation model data, find the spatial range of each installation part, take the spatial range of each installation part as the reference point, combine the physical part features of each installation part, find the geometric feature point closest to the point on the physical part features, and use the nearest geometric feature point as the optimal annotation reference point.

[0060] Finally, the installation part number marking plane is constructed through the optimal marking reference points, spatial range and construction information of each installation part, the part number marking content is obtained from the installation part model data, and the part number marking content is marked on the installation part number marking plane.

[0061] For example, the 10-16 characters (GS-2001) of the name of the installation structure are intercepted as the part number annotation content. Based on the construction status of a certain installation part obtained as: reverse state, the installation perspective is: bow (looking from the bow to the stern), and the approximate area where the installation part is located is: port side; the created annotation plane should be parallel to the XZ plane of the ship design coordinate system. Since the current actual construction status is: reverse state, after the current part number annotation is created, it is rotated 180 degrees, and the part number is moved to the optimal position according to the spatial position of the installation part.

[0062] Specifically, the step of making the installation part model data correspond to the installation background model and marking the installation part positioning information on the three-dimensional model of the ship in combination with the installation background model includes:

[0063] First, in the product structure tree of the ship, select any outfitting installation node and the model node of each installation background model. In this embodiment, according to the modeling method of the installation parts and the installation positioning requirements, the following three annotation principles are included:

[0064] Principle 1: Use the model’s specific feature objects as the positioning basis and combine them with the background model to annotate the positioning information;

[0065] Principle 2: Use the outer contour of the model entity as the positioning basis and combine it with the background model to mark the positioning information;

[0066] Principle 3: Use the created model auxiliary lines as the positioning basis and combine the rib position features to mark the positioning information.

[0067] Next, traverse the product selection structure tree nodes, and filter the outfitting installation nodes according to the node screening conditions to obtain the outfitting installation nodes that meet the requirements. Each node can be a lightweight model;

[0068] Then, the corresponding installation background models are matched in turn according to the node types of the outfitting installation parts, and the annotation reference elements of the installation part positioning information are found therein.

[0069] For example, sacrificial anodes and drain plugs are marked using principle 1; ladders and platforms are marked using principle 2; and manhole covers and small hatch covers are marked using principle 3.

[0070] Finally, based on the marked reference elements, the spatial position relationship between the outfitting installation parts and the installation background model is combined, and the positioning information of the background model in the specified direction and within a predetermined range from the outfitting installation parts is marked.

[0071] The following are examples of installation part location information annotations in three backgrounds:

[0072] Scenario 1: Based on the positioning of a specific feature object in the model, retrieve the model features of the mounting part, obtain the feature object with the specified name, use the obtained feature object as the reference feature, and mark the distance to the nearest structural part or the same type of mounting part.

[0073] Scenario 2: Based on the outer contour of the model entity, obtain the boundary geometric features of the mounting parts, use the boundary geometric features of the mounting parts as reference features, and mark the distance to the nearest structural parts or the theoretical surface of the ship (reference plane, midship surface, etc.).

[0074] Scenario 3: Based on the created model auxiliary lines, obtain the specified positioning points in the mounting parts, create auxiliary lines in the X and Y directions of the specified axis according to the mounting direction of the mounting parts, and then use the created auxiliary lines as reference features to mark the distance to the nearest structural part or the distance to the rib plane, such as FR50. +300 .

[0075] Specifically, the step of making the installation part model data correspond to the installation background model, and marking the installation part installation process information on the three-dimensional model of the ship in combination with the installation background model includes:

[0076] First, in the product structure tree of the ship, select any outfitting installation part node and the model node of each installation background model. In this embodiment, the installation process information of the installation part mainly includes welding information and painting information. The specific installation process of the installation part needs to be selectively added in time according to the actual construction scene. There are three specific scenes:

[0077] Scenario 1: Installation process requirements between installation parts and structures or other specialties;

[0078] Scenario 2: Installation process requirements between installation parts;

[0079] Scenario 2: Installation process requirements for individual installation parts.

[0080] Then, according to the node screening conditions, the outfitting installation nodes are screened to obtain the outfitting installation nodes that meet the requirements;

[0081] Finally, the installation process information of the installation parts is marked according to the actual assembly sequence and construction process requirements of the outfitting installation parts.

[0082] Among them, the marking of installation process information of installation parts according to the actual assembly sequence and construction process requirements of outfitting installation parts includes: obtaining the actual welding contour of the installation parts during the assembly process, and marking the corresponding welding process symbols based on the welding contour according to the welding information requirements; obtaining the area and paint brand required for painting of the installation parts, and modifying the display color of the painting area according to the color corresponding to the paint brand to mark the painting process; retrieving the characteristic parameter information in the installation part model structure, and marking the installation process information in sequence according to the parameter information content.

[0083] The marking method for ship outer outfitting installation information described in this embodiment can realize efficient and fast marking of installation information based on installation delivery model data. While ensuring the installation of installation delivery information, it can achieve unified marking style, reduce design marking errors, and reduce the generation of redundant marking information. At the same time, it can also effectively improve the drawing recognition efficiency of designers.

[0084] This embodiment also provides a computer-readable storage medium on which a computer program is stored. When the program is executed by a processor, the following is achieved: Figure 1 The marking method described.

[0085] At any possible level of technical detail combination, the present application may be a system, method and / or computer program product.

The installation part positioning information is divided into specific installation positioning information of parts and components, which can be concisely expressed in the form of size, text, etc. The installation part installation process information is divided into welding information, coating information, and process requirements.

[0094] In this embodiment, the marking rules of the ship's outer outfitting installation information require that the basic information of the installation parts shall be marked with a unified identification character code for text marking, that the positioning information of the installation parts shall be based on the characteristic structure and modeling method of each installation part, and the marking principles of the installation information of the same type of installation parts shall be sorted out, and that the installation process information of the installation parts shall be based on the welding process requirements (including weld angle height, welding type, etc.) to determine the welding process symbols corresponding to different process requirements, and the painting process information shall be based on the paint type to determine the one-to-one relationship between the paint brand and the display color. When marking the process requirements, the process designer shall define the process requirements in advance in the form of model parameters, and the process information shall be marked directly based on the specific parameter information.

[0095] The auxiliary labeling module 22 is used to configure the global coordinate system of ship design based on the ship type rib position parameters, construct the ship type rib position plane information on the ship design global coordinate system, find the spatial range corresponding to any node model in the ship's product structure tree, construct the ship type rib position plane features within the spatial range corresponding to the node model, and label the constructed ship type rib position plane features with the corresponding ship type rib position names.

[0096] Specifically, the auxiliary marking module 22 determines the center coordinates of each rib plane in the X, Y, and Z axis directions of the global coordinate system of the ship design, so as to construct the ship type rib plane information according to the center coordinates of each rib plane; traverses the spatial range of each node model, and superimposes the obtained spatial ranges in turn to obtain the calculated maximum spatial range value and the minimum spatial range value to form the superimposed spatial range; according to the ship type rib position parameters and the superimposed spatial range, the ship type rib plane is screened out within the superimposed spatial range, and the ship type rib plane feature is constructed within the spatial range, and the corresponding ship type rib name is marked on the constructed ship type rib plane feature.

[0097] The labeling module 23 is used to label the installation part number information based on the installation part model data and the actual construction status of the current section / area / section of the ship; correspond the installation part model data with the installation background model, and label the installation part positioning information of the three-dimensional model of the ship in combination with the installation background model; and / or correspond the installation part model data with the installation background model, and label the installation process information of the installation part of the three-dimensional model of the ship in combination with the installation background model.

[0098] Specifically, the annotation module 23 selects any outfitting installation part node in the product structure tree of the ship; traverses the nodes of the product selection structure tree, and screens the outfitting installation part nodes according to the node screening conditions (in this embodiment, the screening conditions include information such as specific node types and specific attribute values) to obtain installation parts that meet the requirements; according to the segment and area where the outfitting installation parts are located, the construction information generated in the current actual construction process is obtained (the construction information includes the construction status and the installation perspective. Among them, the construction status: because in the actual construction, for the segments with curved outer plates, there is an external field turning over situation (rotating 180 degrees along the center line or rotating based on the change of the outer plate linear ratio), the construction status is divided into: normal, reverse, and lying. Installation perspective: because the installation parts are widely distributed, the installation perspective is divided into: looking down, looking up, bow, stern, port, and starboard). According to the model data of the mounting parts, the spatial range of each mounting part is found. Taking the spatial range of each mounting part as the reference point, combined with the physical part features of each mounting part, the geometric feature point closest to the point is found on the physical part features, and the nearest geometric feature point is used as the optimal annotation reference point. The mounting part part number annotation plane is constructed through the optimal annotation reference point, spatial range and construction information of each mounting part, and the part number annotation content is obtained from the mounting part model data, and the part number annotation content is annotated on the mounting part part number annotation plane.

[0099] The labeling module 23 selects any outfitting installation part node and the model node of each installation background model in the product structure tree of the ship. Traverse the product selection structure tree nodes, and filter the outfitting installation part nodes according to the node screening conditions to obtain the outfitting installation part nodes that meet the requirements. Each node can be a lightweight model. According to the node type of the outfitting installation part node, the corresponding installation background model is matched in sequence, and the labeling reference element of the installation part positioning information is found therefrom. Based on the labeling reference element, the spatial position relationship between the outfitting installation part and the installation background model is combined, and the positioning information of the background model in the specified direction and within a predetermined range of the distance from the outfitting installation part is labeled.
