[0041] The above description is only an overview of the technical solution of the present invention.

In order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are listed below. DETAILED DESCRIPTION

[0042] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0043] The following, in conjunction with the accompanying drawings, describes in detail the CATIA-based cable channel cross-section visualization method, device, and electronic device provided in the embodiments of the present application through specific embodiments and their application scenarios.

[0044] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0045] Embodiment 1 of the present invention relates to a cable channel cross-section visualization method based on CATIA, the process of which is as follows: Figure 1 As shown, it includes responding to the data selection operation input by the user, obtaining the target cable channel data packet and the target cable laying data packet, drawing the support and hanger exterior according to the target cable channel data packet, arranging the cables according to the target cable laying data packet and the support and hanger exterior contour, generating a cable arrangement diagram, dividing the channel segments based on the cable arrangement diagram, and calculating the cable filling rate corresponding to each divided channel segment, responding to the channel segment selection instruction input by the user, selecting the target channel segment according to the cable arrangement diagram, generating and displaying the target channel cross-sectional view of the target channel segment, and displaying the corresponding target cable list and the cable filling rate corresponding to the target channel segment.

[0046] S1: In response to a data selection operation input by a user, a target cable channel data packet and a target cable laying data packet are obtained.

[0047] In this embodiment, Figure 7 As shown, select the required cable channel data package and cable laying data package on the product structure tree.

[0048] Among them, the product structure tree is divided according to the product model-general section-area-system-data package-part level, which is a product structure directory for managing three-dimensional data packages.

[0049] It should be noted that the cables on the ship are directly fixed through supports and hangers. In the three-dimensional design process, in order to ensure the overall balance, the cable channel must be drawn first to occupy the position. The supports and hangers are arranged according to the cable channel. There is no cable channel entity in the actual ship construction process.

[0050] Furthermore, there is no physical cable model in CATIA 3D design, only a virtual connection path represents the head and terminal devices of the cable connection. Cable laying refers to the process of arranging the cables according to the specified cable channel path.

[0051] S2: Draw the outer contour of the support bracket according to the target cable channel data packet.

[0052] The cable channel specifications match the cable support and hanger specifications. By obtaining the cable channel specification attributes, the corresponding support and hanger outer contour can be drawn.

[0053] like Figure 10-12 As shown, the specification properties of the selected cable channel will be automatically read, and the section type will be selected according to the cable channel name. Take the U-shaped section as an example:

[0054] When the cable channel name is read as A90X280, the cable channel cross-section drawing program will automatically query the specification of the channel in the database based on the name. A means that the cable channel support and hanger is a tight hook type, and the cross-section of the tight hook type is U-shaped. According to the naming rules, the cable channel outline is automatically judged to be a 90X190 rectangle plus a semicircle with a diameter of 90.

[0055] In addition, if the name is 2_B1_40, B means that the cable channel support bracket is a flat steel type, and the cross-section of the flat steel type is rectangular.

[0056] S3: Arrange the cables according to the target cable laying data package and the outer contour of the support and hanger to generate a cable arrangement diagram.

[0057] There is no physical model of the cable in the CATIA three-dimensional design. After the cable is laid, only the cable code information passing through is recorded in the channel. During the ship electrical design process, each cable has a unique code. In this embodiment, the cable outer diameter and other information are automatically searched in the background database based on the cable code.

[0058] According to the cable laying process requirements and related algorithms, the cables are automatically arranged according to the relevant process requirements. For specific arrangement methods, see S31-S35.

[0059] In this embodiment, Figure 2 As shown, S3 may include the following steps:

[0060] S31. When the target cable channel data packet includes an existing cable outline, the cables are arranged according to the existing cable outline and the outer outline of the support bracket, and the cables are arranged in a manner of being tangent to the existing cable outline.

[0061] S32. When the target cable channel data packet does not include the existing cable contour, the cables are arranged according to the outer contour of the support and hanger, and the cables are arranged in a manner of being inscribed within the outer contour of the support and hanger.

[0062] S31-S32 are judgment steps. Before cable arrangement, the cable channel data is confirmed, including the support and hanger outlines and whether there are existing cables, to ensure automatic identification of the support and hanger outlines and the existing cable outlines, and to arrange them externally without indenting, intersecting or overlapping with existing objects.

[0063] S33. Based on the cable laying process requirements, the cables are arranged in a way that the cables are thin at the top and thick at the bottom.

[0064] like Fig. 9 As shown, according to the shipyard construction requirements, the thick cables are laid first and the thin cables are laid later. The cables are arranged to ensure that the thick cables are at the bottom and the thin cables are arranged at the top. When the thick cables are arranged on the lower layer, the thin cables will be automatically arranged above the thick cables.

[0065] It should be noted that the cable cross-section marked with “×” in the figure is an example of an incorrect arrangement. Under normal arrangement, a thin cable at the bottom will not appear.

[0066] S34. Arrange the cables according to the three-dimensional global spatial directions of the cables included in the target cable channel data packet, with the cables that turn first being on both sides and the cables that turn later being in the middle.

[0067] According to the three-dimensional global spatial direction of the cable, ensure that the first bends are on both sides and the last bends are in the middle, so as to ensure that the global cable laying results are beautiful and smooth. Fig.13 As shown, if cable No. 10 turns first, it needs to be arranged from "×" to the side.

[0068] S35. Arrange the cables in a manner with a lowest total floor height, wherein the total floor height is the height at which the vertex of the highest-positioned cable is located.

[0069] When arranging cables, the minimum total floor height will be guaranteed. Fig.14 As shown, cable No. 8 originally determined the floor height at the "×". Through adjustment, it was changed from the "×" to the middle arrangement, and the arrangement method with the lowest total floor height was obtained.

[0070] S4. Divide the channel segments based on the cable layout diagram, and calculate the cable filling rate corresponding to each divided channel segment.

[0071] In this embodiment, Figure 3 As shown, S4 may include the following steps:

[0072] S41. Based on the cable layout diagram, the cable channels are divided and named according to the specification attributes of the cable channels.

[0073] In order to facilitate designers to quickly locate the corresponding channel section, a unique section name will be generated for each cable channel section. This name corresponds to the cable channel name. Each cable channel section will automatically generate a corresponding cable list (code and outer diameter information) to facilitate designers to quickly view.

[0074] S42: Calculate the cable filling rate corresponding to the channel section according to the cable channel specification and dimension information of the channel section and the cable outer diameter.

[0075] like Fig.17As shown, the cable channel filling rate will have a certain margin due to shipyard construction, generally not exceeding 80% of the cable channel cross-section.

[0076] S5. Respond to the channel segment selection instruction input by the user, select the target channel segment according to the cable layout diagram, generate and display the target channel cross-sectional view of the target channel segment, and display the corresponding target cable list and the cable filling rate corresponding to the target channel segment.

[0077] like Fig.19 As shown, the cable channel cross-section visualization program outputs a diagram including a target channel cross-section diagram, a corresponding target cable list, and a cable filling rate of the corresponding target channel segment.

[0078] In this embodiment, before generating and displaying the target channel cross-sectional view of the target channel segment in S5, the following steps may also be included:

[0079] S51. Based on the target cable list, make adjustments in response to the user's movement operation to obtain the corresponding target cable list.

[0080] The cable layout is automatically arranged through the cable channel section drawing program. When the layout does not conform to the on-site construction conditions, the cable position can be quickly adjusted manually by moving the cable code up and down in the section drawing program.

[0081] like Figure 15-16 As shown, first select the cable to be moved, and then click "Move Up" or "Move Down" to quickly adjust the cable arrangement results. Fig.15 This is a schematic diagram before quick adjustment. Fig.16 This is the result diagram after quick adjustment.

[0082] In addition, the present invention can also select multiple cable channel sections at one time to generate a cable layout diagram, such as Figure 8 As shown, each cable channel section will generate a unique section name, which corresponds to the cable channel name. Each cable channel section will automatically generate a corresponding cable list (code and outer diameter information). Designers can select multiple channel sections at the same time and generate cable lists at the same time to quickly view the cable arrangement of the target channel section and improve efficiency.

[0083] Furthermore, the three-dimensional cable laying and cable layout diagram of the present invention are based on CATIA software. When the cable channel specifications or cable laying status change, the support bracket outline, cable code, cable outer diameter, layout diagram, filling rate and other information in the cable layout diagram can be automatically updated.

[0084] Furthermore, in order to meet the need to conduct a preliminary evaluation of the cable channel specifications in the early stage of design in order not to affect the overall balance due to the late cable laying work, the present invention also supports manual entry of cable attribute information for preliminary evaluation.

[0085] Specific as Fig.18 As shown, in the cable channel cross-section drawing program, select the cable channel to be evaluated, and output the cable channel specifications and other information locally. Manually enter the pre-laid cable outer diameter and other information in the output Excel file (the black box part in the figure is the manually entered information). Import the Excel file with complete information into the cable channel cross-section drawing program, and you can generate the cable layout diagram and filling rate based on the entered information. In the early stage, the filling rate of the main cable channel generally does not exceed 50% of the cable channel. The calculation results of the filling rate can assist designers to correct the channel specifications in the early stage of design.

[0086] This embodiment can automatically generate a cable layout diagram suitable for guiding on-site construction based on the three-dimensional cable laying results and on-site construction process requirements, which can save personnel time in drawing and greatly improve design efficiency. The cable layout diagram and cable laying are based on the same platform, which can realize the automatic update of the cable layout diagram following the changes in the cable laying results, ensuring the consistency of the cable information in the cable layout diagram and the cable laying results. Automatically matching cable code information and outer diameter information ensures the accuracy and completeness of the information.

[0087] Another embodiment of the present invention relates to a cable channel cross-section visualization device 200 based on CATIA, such as Figure 4 As shown, including:

[0096] The height arrangement module 2035 is used to arrange the cables in an arrangement manner with the lowest total floor height, wherein the total floor height is the height at which the top point of the highest-positioned cable is located.

[0097] Further, such as Figure 5 As shown, the cable arrangement module 203 also includes:

[0098] An external tangent arrangement module 2031 is used to arrange the cables according to the existing cable outline and the external outline of the support and hanger when the target cable channel data packet includes an existing cable outline, and arrange the cables in a manner of external tangent to the existing cable outline;

[0099] The inscribed arrangement module 2032 is used to arrange the cables according to the outer contour of the support and hanger when the target cable channel data packet does not include the existing cable contour, and arrange the cables in a manner of inscribed with the outer contour of the support and hanger.

[0105] This embodiment can automatically generate a cable layout diagram suitable for guiding on-site construction based on the three-dimensional cable laying results and on-site construction process requirements, which can save personnel time in drawing and greatly improve design efficiency. The cable layout diagram and cable laying are based on the same platform, which can realize the automatic update of the cable layout diagram following the changes in the cable laying results, ensuring the consistency of the cable information in the cable layout diagram and the cable laying results.
