Description

Technical Field

[0001] The present invention relates to the technical field of ship design, and in particular to a ship cable channel design method, storage medium and computer equipment. Background Art

[0002] The cable channel is an expression of the direction and space occupied by the cables in the ship, and is an important input for the cable laying and cable tray layout. In the three-dimensional design of the ship, it is used for comprehensive layout and cable wiring design. It can not only express the connection relationship between the cable and the equipment, but also record the cable information and cable tray information carried. The channels are connected to form a network. Therefore, the cable channel network is like a "highway" in the ship, extending in all directions and running through the entire ship.

[0003] Since the design of large ships is a collaborative design of multiple disciplines, cable channel planning and space reservation design are usually carried out in the early stage of ship design. The quality of cable channel design not only affects the design and laying efficiency of cables, but also seriously affects the space utilization and performance of ships. The cable channel consists of trunk cable channels and regional cable channels. The traditional trunk cable channel and regional cable channel design are to select or input the space starting point nearby, and then plan the intermediate point (way point) and end point according to the comprehensive layout of the hull structure and equipment, and select the appropriate cable channel specifications and parameters to create a cable channel model based on the actual reserved space or the estimated maximum cable carrying capacity.

[0004] The spatial starting point, middle point, approach point, branch point, and end point selected or picked up during the cable channel design process will all reference or refer to the design objects in the ship. However, in the process of multi-disciplinary collaborative design, these referenced or referenced objects will be continuously iterated, and any change in these objects for any reason will change the direction and spatial position of the cable channel. The existing cable channel design cannot be updated in time, resulting in large-scale errors in the cable channel, cable wiring design failure caused by path loss, and mismatch with cable bracket modeling. Summary of the invention

[0005] In view of the shortcomings of the prior art described above, the object of the present invention is to provide a ship cable channel design method, storage medium and computer equipment, which are used to solve the problem that the cable channel design in the prior art cannot be updated in time according to the changes of the referenced or referenced objects, thereby causing large-scale errors in the cable channel, path loss leading to cable wiring design failure and mismatch with cable bracket modeling.

[0018] Optionally, before constructing the ship-wide cable channel structure tree and the ship-wide cable channel skeleton structure tree, it is necessary to obtain ship design drawings or models to collect information reflecting the ship's main dimensions, area divisions, deck layouts, cabin divisions, structural benchmarks, special cabins, spatial relationships, and main equipment layouts.

[0023] Another aspect of the present invention provides a computer device, including a memory, a processor, and a machine executable program stored in the memory and running on the processor, and when the processor executes the machine executable program, the ship cable channel design method described above is implemented.

[0031] Refer to the following Figures 1 to 6 To describe a ship cable channel design method, storage medium and computer device of the present invention. In the description of this embodiment, the reference terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" refer to the specific features, structures, materials or characteristics described in conjunction with the embodiment or example included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0032] like Figure 1-Figure 4 As shown, an embodiment of the present invention provides a ship cable channel design method, comprising:

[0033] Step S1, construct a structure tree of the cable channel of the whole ship, and divide the cable channel network of the whole ship into regions according to the ship deck and the ship cabin. Specifically, the spatial composition information of the ship is obtained, and the spatial composition of the ship is combined, and a top-down division method is adopted to divide the cable channel network of the whole ship into regions according to the ship deck or cabin, so as to construct a structure tree of the cable channel of the whole ship.

[0034] Step S2, build a structure tree of the cable channel skeleton of the whole ship, create the deck reference plane skeleton and bulkhead reference plane skeleton of each area, and create corresponding reference planes and coordinate systems for the deck reference plane skeleton and bulkhead reference plane skeleton. Among them, the reference plane is used to establish the association between the deck reference plane skeleton and the bulkhead reference plane skeleton and the whole ship. That is, by referencing and referencing the coordinate system of the whole ship, the relative relationship between the deck reference plane and bulkhead reference plane of each area and the baseline of the ship is guaranteed and controlled. When the reference plane changes, the deck reference plane skeleton and the bulkhead reference plane skeleton will also change accordingly. The coordinate system is used to describe the geometric entities of the deck reference plane skeleton and the bulkhead reference plane skeleton to facilitate the selection of the geometric entities of the deck reference plane skeleton and the bulkhead reference plane skeleton. The geometric entities include points, lines, and surfaces that need to be referenced or referenced to create the cable channel.

[0035] Furthermore, the design method also includes creating corresponding control parameters for the deck reference plane framework and the bulkhead reference plane framework. The control parameters can be used to modify the relative relationship between the deck reference plane and the bulkhead reference plane of each region and the ship baseline. By setting the control parameters, the position of the deck reference plane and the bulkhead reference plane of each region in the ship can be determined more accurately, and the position can be adjusted conveniently.

[0036] Step S3, build a cable channel parametric resource specification library to obtain the specifications of the cable channel design. Combined with the cable laying requirements and modeling requirements, a cable channel parametric resource specification library is established in accordance with design conventions. Specifically, by creating a channel shape outline template and specification control parameters, it is possible to quickly select and retrieve the specifications of the cable channel design from the cable channel parametric resource specification library when creating the cable channel, and the specifications of the cable channel can be changed by modifying the specification control parameters. Among them, the shape outline template includes circle, rectangle, square, and trapezoid. The specification control parameters include shape control parameters, channel ratio parameters, adaptive adjustment parameters, and color matching parameters.

[0037] Step S4, selecting the area where the cable channel is currently required to be created in the ship-wide cable channel structure tree, so as to create the cable channel under the area.

[0038] Step S5, select the corresponding deck reference plane skeleton and / or bulkhead reference plane skeleton in the whole ship cable channel skeleton structure tree, and obtain the points, lines, and surfaces required for reference or reference to create the cable channel. That is, according to the area where the cable channel is currently to be created selected in step S4, select the corresponding area in the whole ship cable channel skeleton structure tree, and select points, lines, and surfaces in the deck reference plane skeleton and / or bulkhead reference plane skeleton corresponding to this area as the starting point, middle point, path point, branch point, and end point of the new cable channel, thereby determining the path of the cable channel.

[0039] Step S6, selecting the cable channel specification from the cable channel resource specification library, and then determining the specification of the cable channel, that is, the shape and size.

[0040] Step S7, completing the creation of the cable channels in each area according to the paths and cable channel specifications obtained in steps S5 and S6.

[0041] In summary, by dividing the entire ship in different ways, establishing the corresponding cable channel structure tree and cable channel skeleton structure tree for the entire ship, and creating a cable channel parameterized resource specification library, the path and specifications for cable channel creation can be obtained, thereby realizing the design of cable channels in various areas of the entire ship. In addition, since the deck reference plane skeleton and bulkhead reference plane skeleton are associated with the entire ship through reference surfaces, in the process of multi-disciplinary collaborative design, when the ship design changes, the created deck reference plane skeleton and bulkhead reference plane skeleton will change accordingly, and the geometric entities of the deck reference plane skeleton and bulkhead reference plane skeleton described by the coordinate system will also change, thereby changing the points, lines, and surfaces referenced or referenced by the cable channel creation, thereby realizing the automatic update of the cable channel, so that the subsequent laying of the cable channel is more accurate.

[0042] Furthermore, before selecting the corresponding cable channel specification in the cable channel resource specification library, it also includes obtaining the cable design information. According to the design information, the corresponding cable channel specification is selected. That is, according to the cable design information, the total area of ​​each cable is calculated, and the cable channel specification is selected according to the load, proportion, and filling rate requirements of the cable channel to adjust the size of the cable channel or display the color of the cable channel, so as to make the cable channel design more comprehensive. Among them, different proportion intervals match different colors.

[0043] In some other embodiments of the present invention, after selecting the corresponding cable channel specification in the cable channel resource specification library, it also includes obtaining the design information of the cable. According to the design information, the corresponding cable channel specification is updated. That is, according to the design information of the cable, the total area of ​​each cable is calculated, and according to the load, proportion, and filling rate requirements of the cable channel, the selected cable channel specification is updated to adjust the applicability of the cable channel size or update the color display of the cable channel, so as to make the cable channel design more comprehensive. Among them, different proportion intervals match different colors.

[0044] Furthermore, before constructing the ship-wide cable channel structure tree and the ship-wide cable channel skeleton structure tree, it is necessary to obtain the ship design drawings or models to collect information used to reflect the ship's main dimensions, area division, deck layout, cabin division, structural benchmark, special cabin, spatial relationship, and main equipment layout. Among them, the ship design drawings or models include the ship type general plan, structural layout plan, cabin layout plan, and engine room layout plan.
