Subsequently, the design drawings will be submitted to the shipowner and the classification society (ship inspection) for approval, and the shipyard will make multiple modifications according to the modification opinions to obtain the modified design drawings.

For example, a plurality of processing units refers to two or more processing units, and a plurality of elements refers to two or more elements, etc.

[0028] The first aspect of the present application provides a method for reviewing a ship structure, which includes the following steps:

[0029] An acquisition step of acquiring a two-dimensional structure diagram of the hull structure and parameter information of the hull structure;

[0030] A classification step of classifying the two-dimensional structure diagrams of the hull structure according to the hull area positions;

[0031] A modeling step of, for different area positions of the hull, selecting the two-dimensional structure diagrams of the hull structure corresponding to the area positions, and establishing three-dimensional models of the hull structure corresponding to the area positions according to the two-dimensional structure diagrams of the hull structure corresponding to the area positions;

[0032] Reference step: For different regional positions of the hull, select the parameter information of the hull structure corresponding to the regional position, and add the parameter information of the hull structure corresponding to the regional position into the three-dimensional model of the hull structure corresponding to the regional position;

[0033] Review step: Compare the parameter information in the three-dimensional model of the hull structure with the parameter information in the two-dimensional structure diagram of the hull structure corresponding to the regional position.

[0034] In the acquisition step, the two-dimensional structure diagrams of the hull structure include a transverse section structure diagram, a longitudinal section structure diagram, and a horizontal plane structure diagram according to the section type. Refer to Figure 1 , the hull structure is a floor structure, Figure 1 is the transverse section structure diagram of the floor structure.

[0035] The transverse section structure diagram corresponds to the hull transverse section. The hull transverse section can be represented by X. For example, X-51 represents the transverse section at the 51st number, and X-63 represents the transverse section at the 63rd number. X-51 to X-63 represents the range between the transverse section at the 51st number and the transverse section at the 63rd number. For example, the transverse section at the 51st number corresponds to the hull floor plane FR50+100, that is, it represents the position 100 mm along the ship length direction from the hull floor plane FR50. The transverse section at the 63rd number corresponds to the hull floor plane FR63+200, that is, the position 200 mm along the ship length direction from the hull floor plane FR63.

[0036] The longitudinal section structure diagram corresponds to the hull longitudinal section. The hull longitudinal section can be represented by Y. Y-CL represents the hull center plane. The hull center plane is a longitudinal plane passing through the hull center line and perpendicular to the base plane. Here, the base plane is a plane passing through the upper edge of the center girder of the hull middle part and parallel to the load water plane. For example, Y-30S represents the longitudinal section at the 30th number on the right side of the hull center plane with the hull center plane as the reference, where S represents the starboard side. Correspondingly, Y-30P represents the longitudinal section at the 30th number on the left side of the hull center plane with the hull center plane as the reference, where P represents the port side. Then Y-30S to Y-30P represents the range between the longitudinal section at the 30th number on the right side of the hull and the longitudinal section at the 30th number on the left side of the hull. Y-30S to Y-30P can also be represented by Y-30S to Y-CL to Y-30P.

[0037] The horizontal plane structure diagram corresponds to the hull deck platform horizontal plane. The hull deck platform horizontal plane can be represented by Z. Among them, Z-0 represents the base plane mentioned in the above text. Z-30000 represents the horizontal plane 30 meters away from the base plane.

[0038] In the acquisition step, the parameter information of the hull structure includes boundary parameters, seam parameters, opening parameters, stiffener positioning parameters, and annotation data. The boundary parameters are used to determine the boundary position of the hull structure in the three-dimensional model. The seam parameters are used to determine the position, shape, and size of the seams in the three-dimensional model. The opening parameters are used to determine the position, shape, and size of the openings in the hull structure in the three-dimensional model. The stiffener positioning parameters are used to determine the position, shape, and size of the stiffeners in the hull structure in the three-dimensional model. The annotation data is used to determine data such as the plate thickness, material, and specifications of the hull structure in the three-dimensional model.

[0039] In the classification step, the two-dimensional structure diagrams of the hull structure are classified according to the hull area position, and the hull area position refers to the area position classified during the shipbuilding process. For example, during the shipbuilding process, the hull is divided along the ship length direction into a total of eight areas, namely the starboard and port sides of the bow, the starboard and port sides of the mid-fore part of the ship, the starboard and port sides of the mid-aft part of the ship, and the starboard and port sides of the stern. The two-dimensional structure diagrams of the hull structure can also be divided into eight categories according to these eight areas, which are respectively represented by M01 to M08. Each area includes a range interval in the horizontal, longitudinal, and transverse directions. For example, M04 represents the cuboid space surrounded by the height range from the horizontal plane 2 meters away from the base plane to 30 meters away from the base plane, the longitudinal range between the longitudinal section at the 30th number on the starboard side of the hull and the longitudinal section at the 30th number on the port side of the hull, and the transverse range between the transverse section at the 51st number and the transverse section at the 63rd number.

[0040] In some embodiments, in the classification step, while the two-dimensional structure diagrams of the hull structure are classified according to the hull area position, they are also classified according to the cross-sectional view type. Further, in the modeling step, according to the hull area position and the cross-sectional view type, the two-dimensional structure diagrams of the hull structure corresponding to the corresponding area position are selected.

[0041] In the modeling step, establishing the three-dimensional model of the hull structure corresponding to the corresponding area position based on the two-dimensional structure diagram of the hull structure corresponding to the corresponding area position includes: obtaining the correspondence between the coordinate system in the three-dimensional modeling software and the horizontal, transverse, and longitudinal directions of the hull structure, obtaining the position of the two-dimensional structure diagram of the hull structure in the coordinate system of the three-dimensional modeling software according to the correspondence between the coordinate system in the three-dimensional modeling software and the horizontal, transverse, and longitudinal directions of the hull structure, and then establishing the three-dimensional model of the hull structure corresponding to the corresponding area position.

[0042] The following uses the floor structure to exemplify the modeling step of the present application. The modeling step specifically includes the following steps:

[0043] Determine the regional location of the hull where the floor structure is located, and select the two-dimensional structure diagram of the floor structure in this regional location. For example, select the two-dimensional structure diagram of the floor structure numbered M04-X-63. The number M04-X-63 indicates that the floor structure is within the M04 area during the shipbuilding process, specifically corresponding to the cross-section at the 63rd number. Refer to Figure 2 It is the cross-section structure diagram of the floor structure in this regional location. Figure 2 The parameter information of the floor structure is marked with different colors.

[0044] Specifically, the parameter information of the floor structure includes annotation data, which is represented by the symbols & and %. Among them, the symbol & represents a flat iron of the FL100X10 specification. The FL100X10 specification means that the width of the flat iron is 100 mm and the thickness is 10 mm; the symbol % represents a flat iron of the FL150X10 specification. The FL150X10 specification means that the width of the flat iron is 150 mm and the thickness is 10 mm.

[0045] The parameter information of the floor structure includes boundary parameters and plate joint parameters. The boundary parameters and plate joint parameters include the positions of the boundary and the plate joint, which are located Figure 2 The two white vertical line segments in the middle position represent the position of the plate joint, and the white line surrounding the floor structure represents the position of the boundary.

[0046] The parameter information of the floor structure includes stiffener positioning parameters. The stiffener positioning parameters include the positions of the stiffeners, which are represented by black diagonal lines in Figure 2 it.

[0047] Establishing the three-dimensional model of the floor structure in the corresponding regional location based on the two-dimensional structure diagram of the floor structure in the corresponding regional location includes: obtaining the corresponding relationship between the coordinate system in the three-dimensional modeling software and the horizontal, transverse, and longitudinal directions of the hull structure, obtaining the position of the two-dimensional structure diagram of the floor structure in the coordinate system of the three-dimensional modeling software according to the corresponding relationship between the coordinate system in the three-dimensional modeling software and the horizontal, transverse, and longitudinal directions of the hull structure, and then establishing the three-dimensional model of the floor structure in the corresponding regional location.

[0048] In the reference step, for different regional locations of the hull, select the parameter information of the hull structure in the corresponding regional location, and add the parameter information of the hull structure in the corresponding regional location into the three-dimensional model of the hull structure in the corresponding regional location. For example, add Figure 2 the parameter information of the floor structure in it into the three-dimensional model of the floor structure to obtain the three-dimensional model of the floor structure with the parameter information of the floor structure. Refer to Figure 3 .

[0049] In the review step, compare the parameter information in the three-dimensional model of the hull structure with the parameter information in the two-dimensional structure diagram of the hull structure in the region. For example, refer toFigure 4 , the parameter information in the 3D model of the ribbed plate structure includes the positioning parameters of the stiffeners, and the positioning parameters of the stiffeners are displayed in Figure 4 the content within the square box. The content within the square box is the model review interface, which facilitates the comparison with the parameter information of the 2D structure diagram of the ribbed plate structure at the corresponding regional location.

[0053] A reference module, which is used for different regional locations of the hull, selects the parameter information of the hull structure at the corresponding regional location, and adds the parameter information of the hull structure at the corresponding regional location into the 3D model of the hull structure at the corresponding regional location;
