Description

Technical Field

[0001] The present invention relates to the field of ship technology, and in particular to a ship cabin-penetrating cable channel design method, system, equipment and medium. Background Art

[0002] The ship electrical system has the characteristics of many devices, many interfaces, and many cables. In the process of ship 3D design, in order to improve the efficiency of design modeling, the solid cable model is often not drawn. The solid model of the cable channel with a rectangular or circular cross-section is used to occupy the cable laying space. According to certain design specifications, constraints and process requirements, the minimum path algorithm is used to calculate the cable laying path based on the center line of the cable channel. The cable laying information is output with the hull structure, equipment and cable channel as the background, so as to guide the on-site construction.

[0003] Ship cable channels are divided into two categories: in-cabin cable channels and through-cabin cable channels. Among them, in-cabin cable channels mainly express the path of cables whose starting and ending devices are in the same cabin; through-cabin cable channels are used to express the path of cables whose starting and ending devices are located in different cabins.

[0004] Since the hull and bulkheads are mostly watertight structures, stuffing boxes and other welded parts are generally used to seal the cables when they pass through the cabin. Each opening in the stuffing box corresponds to a cable, but the cable laying path expression method based on the center line of the channel does not reflect the arrangement of the cables in the channel, and cannot accurately express the number of cables passing through the specific openings of the stuffing box. As a result, the cable path through the cabin cannot be expressed through a three-dimensional model, and the cable laying path can only be manually selected and expressed through a two-dimensional diagram. Summary of the invention

[0005] In view of the technical problem that the path of the through-cabin cable in the prior art cannot be expressed through a three-dimensional model, the purpose of the present invention is to provide a method, system, equipment and medium for designing a through-cabin cable channel for a ship, by parametrically defining a virtual through-cabin channel connector and automatically adjusting the openings and connection interfaces of the through-cabin channel connector based on the number of cable openings in the stuffing box, and establishing a channel branch for each cable separately, thereby improving the traditional information expression method of cable laying based on drawings.

[0006] In order to solve the above problems, the first object of the present invention is to provide a method for designing a ship's through-cabin cable channel, based on a cable channel entity model in a three-dimensional software as a cable laying space placeholder, the design method comprises the steps of:

[0015] Furthermore, in step S 200 These also include:

[0016] According to the size of the stuffing box and the cable channel, the design parameters of the virtual cabin penetration cable channel connector model are adjusted.

[0017] Furthermore, in step S 300 The specific operation of using the shortest path algorithm to calculate the cable laying path through the cabin includes:

[0018] Step S 310 :The shortest path S0 is obtained by Dijkstra algorithm. Based on the shortest path, the second shortest path can be obtained by using the second shortest path algorithm. The second shortest path algorithm is continued to be used on the basis of the second shortest path. This cycle is repeated m-1 times to obtain the first m shortest paths S1, S2…S m ;

[0019] Step S 320 :The paths S1, S2…S obtained through the second shortest path are extended again by the path extension method. m Expand and get p extended paths S 11 , S 12 …S 1P , S 21 , S 22 …S 2p …S m1 , S m2 …S mp ;

[0020] Step S 330 : Finally, the obtained m*p paths are sorted from small to large through a sorting algorithm, and the first k paths are taken as the first k shortest paths.

[0021] Furthermore, the design parameters of the virtual cabin penetration cable channel connector model include a rectangular section length L, a section width W, a circular cable channel radius R, and a circular cable channel spacing D.

[0049] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can also be the internal connection of two components, it can be a wireless connection, or it can be a wired connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0052] In the field of 3D modeling of electrical systems of some large ships, it is necessary to draw cable channels at reasonable locations in the cabin. Cable channels are a kind of virtual space, which is a model used in 3D ship design to represent the total space occupied by cable bundles connecting equipment and record the information of cables passing through.

[0053] Ship cable channels are divided into two categories: in-cabin cable channels and through-cabin cable channels. Among them, in-cabin cable channels mainly express the path of cables whose starting and ending devices are in the same cabin; through-cabin cable channels are used to express the path of cables whose starting and ending devices are located in different cabins.

[0054] Since the hull and bulkhead are mostly watertight structures, the cables are usually sealed by welding parts such as stuffing boxes and stuffing boxes when passing through the cabin, among which:

[0055] Each opening in the stuffing box corresponds to a cable, but the cable laying path expression method based on the center line of the channel does not reflect the arrangement of the cables in the channel, and cannot accurately express the cables passing through the specific openings of the stuffing box. As a result, the cable path through the cabin cannot be expressed through a three-dimensional model, and the cable laying path can only be manually selected and expressed through a two-dimensional diagram. The existing cable design scheme not only reduces the design efficiency, but also easily increases design errors and mistakes.

[0056] To solve the above technical problems, please refer to Figure 1 As shown, an embodiment of the present invention provides a method for designing a ship's through-cabin cable channel, based on a cable channel entity model in a three-dimensional software as a cable laying space occupant, the design method comprises the steps of:

[0057] Step S 100 : Based on the secondary development function of the 3D software, a virtual through-cabin channel connector model 1 and a through-cabin cable channel model 2 are established.

[0058] In this step, considering that all 3D software have secondary development functions, a new model building module is added to the 3D software based on secondary development. Through the model building module, the virtual through-cabin channel connector model 1 and the through-cabin cable channel model 2 are selected and called to prepare for the subsequent three-dimensional expression of the through-cabin cable path in the 3D software.

[0059] Step S 200 : Call and arrange virtual cabin-penetrating cable channel connector models 1 on both sides of the bulkhead 6 respectively, draw stuffing boxes 3 and arrange them at the cabin-penetrating position of the bulkhead 6, connect one end face of each virtual cabin-penetrating cable channel connector model 1 close to the bulkhead 6 with the stuffing box 3, and connect the other end face of each virtual cabin-penetrating cable channel connector 1 away from the bulkhead 6 with the cable channel 4.

[0060] In this step, since the bulkheads of the hull are mostly watertight structures, when the cable 5 needs to pass through the cabin, a stuffing box, a stuffing box 3 and other welded parts are generally used for sealing. For this reason, in the three-dimensional design process, the stuffing box 3 is drawn in three dimensions and arranged at the cabin penetration position of the bulkhead 6. At the same time, in order to accurately express the cable 5 passing through the specific opening of the stuffing box 3, the virtual cabin penetration cable channel connector model 1 is called and arranged on both sides of the bulkhead 6, and each virtual cabin penetration cable channel connector model 1 is close to one end face of the bulkhead 6 (that is, the attached Figure 4 The F end face in the figure) is connected to the stuffing box 3, and the other end face of each virtual through-cabin cable channel connector 1 away from the bulkhead 6 (that is, the attached Figure 2 The B end face in the middle is connected to the cable channel 4 to complete the laying of the cabin cable.

[0061] Step S 300 :The shortest path algorithm is used to calculate the cable laying path through the cabin.

[0062] Step S 400 : Extract the opening numbers for laying cables in each opening of the virtual through-cabin cable channel connector model 1, and associate and output a through-cabin cable laying information table, wherein the through-cabin cable laying information table includes a stuffing box number, an opening number, and a cable number.

[0063]

[0064] Based on the technical problem that the cable path through the cabin cannot be expressed through a three-dimensional model in the prior art, the embodiment of the present invention adopts a design mode of limited secondary development in three-dimensional software, defines a virtual cabin penetration channel connector 1 through parameterization, and automatically adjusts the circular cable channel 11 and the end hole 12 of the virtual cabin penetration channel connector 1 based on the cable opening 21 in the stuffing box 3, thereby establishing a channel branch for each cable separately, thereby realizing the detailed definition and expression of the cable cabin penetration path.

[0065] Specifically, see Figure 2 , 4 , 5, in step S 100 The establishment of the virtual through-cabin channel connector model 1 specifically includes:

[0066] Step S 110 : Establish a virtual cabin cable channel connector model 1 with a rectangular cross section;

[0067] Step S 120 : A plurality of circular cable channels 11 are established in the virtual cabin cable channel connector model 1, and the plurality of circular cable channels 11 form end holes 12 on the end surface of the virtual cabin cable channel connector model 1;

[0068] Step S 130: One end of the plurality of circular cable channels 11 extends to one end surface of the virtual cabin penetration cable channel connector model 1 to form a first end surface hole 121 that is consistent with the number, size, and spacing of the cable openings 31 in the stuffing box 3.

[0069] Therefore, by establishing multiple circular cable channels 11 in the virtual cabin cable channel connector model 1, the purpose is that when connected to the stuffing box 3, the circular cable channels 11 strictly correspond to the cable openings 31 of the stuffing box 3, and each cable opening 31 only allows one cable 5 to be laid.

[0070] Step S 140 : The other ends of the multiple circular cable channels 11 extend and converge in the virtual cabin cable channel connector model 1 to form a first end surface center hole 122.

[0071] It should be specially explained here that the virtual through-cabin channel connector model 1 is only used for the connection and laying path generation of the cable channel 4, and is not part of the ship design BOM table.

[0072] Specifically, step S 200 The method also includes: adjusting the design parameters of the virtual cabin penetration cable channel connector model 1 according to the size of the stuffing box 3 and the cable channel 4.

[0073] See also Figure 4 As shown, specifically in the embodiment of the present invention, the two ends of the virtual cabin cable channel connector model 1 are divided into two faces F and B, wherein:

[0074] The F surface (i.e., the end close to the bulkhead 6, or the first end hole 121 as mentioned above) is used to connect the stuffing box 3, and the number, size, and spacing of the F surface openings (i.e., the first end hole 121) are consistent with the cable openings 31 in the stuffing box 3.

[0075] The B surface (i.e., the end away from the bulkhead 6, or the first end surface center hole 122 as mentioned above) is used to connect the cable channel 4, and each opening of the F surface (i.e., the first end surface hole 121) is connected to the center of the B surface (the first end surface center hole 122) through the circular cable channel 11.

[0076] Specifically, see Figure 3 , 7 As shown, in step S 300 The specific operation of using the shortest path algorithm to calculate the cable laying path through the cabin includes:

[0077] Step S 310:The shortest path S0 is obtained by Dijkstra algorithm. Based on the shortest path, the second shortest path can be obtained by using the second shortest path theorem. The second shortest path algorithm is continued to be used on the basis of the second shortest path. This cycle is repeated m-1 times to obtain the first m shortest paths S1, S2…S m；

[0078] Step S 320 :Use the path expansion method again to find the path obtained through the second shortest path S1 , S2…S m Expand and get p extended paths S 11 , S 12 …S 1P , S 21 , S 22 …S 2p …S m1 , S m2 …S mp ;

[0079] Step S 330 : Finally, the obtained m*p paths are sorted from small to large through a sorting algorithm, and the first k paths are taken as the first k shortest paths.

[0080] The embodiment of the present invention transforms the cable laying path optimization problem into a standard directed graph problem, and proposes an algorithm for the first k shortest paths in the cable laying path mode, namely the k_Dijkstra algorithm, for the standard directed graph based on the second shortest path algorithm, the path extension method and the Dijkstra algorithm, which can effectively help designers improve design efficiency and reduce design errors and mistakes.

[0081] It should be noted that the second shortest path algorithm, the path extension method and the Dijkstra algorithm are all prior arts, and their principles will not be described in detail here.

[0082] Specifically, in a specific embodiment of the present invention, the design parameters of the virtual cabin penetration cable channel connector model 1 include a rectangular cross-sectional length L, a cross-sectional width W, a circular cable channel radius R, and a circular cable channel spacing D.

[0083] Considering that the arrangement position of the stuffing box 3 on the bulkhead 6 changes during the electrical design process, the design parameters of the virtual through-cabin cable channel connector model can be adjusted according to the size of the stuffing box 3 and the cable channel 4. If the size of the stuffing box 3 remains unchanged, there is no need for secondary cable laying and information output.

[0084] Specifically, in the specific embodiment of the present invention, the 3D software is any one of CATIA, CREO and Solidworks. In the embodiment of the present invention, CATIA 3D design software is selected as the development platform in combination with the actual needs of designers, and secondary development is performed based on the CATIA software.

[0089] The cable information association module 400 is used to associate, output and display the through-cabin cable laying information table.

[0092] The ship cable information display module 600 is used to display the published through-cabin cable laying information table.

Moreover, these modules can be implemented in the form of software calling through processing elements; or in the form of hardware; or some modules can be implemented in the form of software calling through processing elements, and some modules can be implemented in the form of hardware.
