[0058] The present invention will be further described below by way of examples, but the present invention is not limited to the scope of the examples described herein.

[0059] Example 1

[0060] Please refer to Figure 1 , which is a flowchart of the selection method for cable penetration parts in this example. Specifically, as Figure 1 shown, the selection method includes:

[0061] S101. Obtain alternative models of cable penetration parts and first parameters of the cable group passing through the cable penetration parts.

[0062] S102. Determine the filling rate of the alternative models based on the first parameters and second parameters of the alternative models; the filling rate is used to characterize the proportion of the total cross-sectional area of the cable group to the cross-sectional area of the cable penetration part.

[0063] S103. Determine the target cable penetration part from the alternative models based on the filling rate of the alternative models.

[0064] The selection method for cable penetration parts in this example determines the filling rate of the alternative models based on the first parameters of the cable group and the second parameters of the alternative models of the penetration parts, and determines the best target cable penetration part from the alternative models based on the filling rate of the alternative models, realizing the automation of the selection of cable penetration parts and improving the efficiency and quality of the selection.

[0065] Example 2

[0066] As Figure 2 shown, the selection method for cable penetration parts in this example is a further improvement of Example 1. Specifically:

[0067] In an alternative implementation, the selection method further includes:

[0068] S201. Build a knowledge base for cable penetration parts; specifically, cable penetration parts are generally divided into two categories: elliptical and circular. As Figure 3 shown, the parameters of the elliptical penetration parts include: alternative models, the long side of the inner wall of the elliptical cable penetration part corresponding to the alternative model, and the short side of the inner wall of the elliptical cable penetration part, etc. As Figure 4 shown, the parameters of the circular penetration parts include: alternative models, the outer diameter of the circular cable penetration part corresponding to the alternative model, and the wall thickness of the circular cable penetration part, etc.

[0069] Step S101 includes:

[0070] S1011. Obtain alternative models of cable penetration parts from the knowledge base of cable penetration parts.

[0071] In another alternative implementation, the selection method further includes:

[0072] S202. Build a cable knowledge base; specifically, as Figure 5 shown, the parameters of the cable include: cable model, the outer diameter of the cable corresponding to the cable model, etc.

[0073] Step S101 includes:

[0074] S1012. Obtain the outer diameter of the cable passing through the cable penetration from the cable knowledge base.

[0075] S1013. Determine the first parameter of the cable group based on the outer diameter and quantity of the cable.

[0076] It should be noted that this embodiment does not limit the order of steps S201 and S202. It is possible to execute step S201 first and then step S202, or execute step S202 first and then step S201, or execute steps S201 and S202 simultaneously. Similarly, this embodiment does not limit the order of steps S1011, S1012, and S1013. It is possible to execute step S1011 first and then steps S1012 and S1013, or execute steps S1012 and S1013 first and then step S1011, or execute steps S1011, S1012, and S1013 simultaneously.

[0077] In an alternative embodiment, step S102 includes:

[0078] S1021. Determine the total cross-sectional area of the cable group based on the first parameter. Specifically, the total cross-sectional area of the cable group can be determined by the following formula:

[0079]

[0080] where di is the outer diameter of the i-th cable, in millimeters (mm), and i = 1, 2,..., n.

[0081] S1022. Determine the cross-sectional area of the alternative model based on the second parameter of the alternative model. Specifically, as Figure 6 shown, the cross-sectional area of the elliptical cable penetration can be determined by the following formula:

[0082] S penetration_T = A * B - ((100 * 100) - (π * 50 * 50));

[0083] where A is the long side of the inner wall of the elliptical cable penetration, and B is the short side of the inner wall of the elliptical cable penetration.

[0084] As Figure 7 shown, the cross-sectional area of the circular cable penetration can be determined by the following formula:

[0085] S penetration_Y = π * ((O.D - 2 * T) / 2) 2 ;

[0086] Wherein, O.D is the outer wall diameter of the circular cable through-hull part, and T is the wall thickness of the circular cable through-hull part.

[0087] S1023. Determine the filling rate of the alternative model based on the total cross-sectional area of the cable group and the cross-sectional area of the alternative model.

[0088] In an alternative embodiment, the model selection method further includes:

[0089] Obtain the relative cross-sectional area of the cable through-hull part; the relative cross-sectional area is used to represent the proportion of the cross-sectional area of the cable through-hull part for passing the cable in the cross-sectional area;

[0090] Step S1023 may include:

[0091] Determine the filling rate of the alternative model based on the total cross-sectional area of the cable group, the cross-sectional area of the alternative model, and the relative cross-sectional area. Specifically, the cable penetration rate can be determined by the following formula:

[0092] Or

[0093] Wherein, δ is the perforation coefficient, which can take a value of 0.3 - 0.4. For large outer diameter cables, a through-hull part with a larger coefficient can be selected, and for small outer diameter cables, a through-hull part with a smaller coefficient can be selected.

[0094] Transpose transformation calculation: The filling rate μ of the relative cross-sectional area (δ0) can be determined by the following formula z :

[0095]

[0096]

[0097] When δ0 is constant (such as taking δ0 = 0.3), the type of the through-hull part is taken as elliptical, and it is required to satisfy δ < δ0. When δ increases, the filling rate μ z increases, and the cross-sectional area S penetration_T decreases. Correspondingly, the minimum cable through-hull model requirement can be obtained, which can save materials and reduce the structural submission difficulty coefficient while meeting the requirements. That is, what needs to be obtained is the maximum μ z value.

[0098] The following is shown through an example. As Figure 8 shown, the input parameters include:

[0099] ① Given the value of δ0, only fill in the integer part before the percentage;

[0100] ② Cable penetration fitting selection (T: oval, Y: round);

[0101] ③ List of cables passing through the bulkhead.

[0102] Parameters in the calculation process include:

[0103] ④ Summary of the total cross-sectional area of the cables;

[0104] ⑤, ⑥ Penetration rate display and minimum cross-sectional area requirement of cable penetration fittings when a given cable penetration rate is set;

[0105] ⑦, ⑧ Relative cross-sectional area filling rate display based on a given cable penetration rate;

[0106] ⑨ Extract basic information of the list of cables passing through the bulkhead based on a given cable sample;

[0107] ⑩ Display of the usage effect of alternative cable penetration fittings.

[0108] The output result shows:

[0109] Recommendation for cable penetration fitting selection;

[0110] Display of the relative filling rate when selecting recommended cable penetration fittings.

[0111] In another example, as Figure 9 shown, the filling rate cannot exceed 100%, so the model corresponding to the maximum filling rate within 100% is selected.

[0112] In addition, when a suitable model cannot be selected for the current cable group, the cable group is split, and then the cable penetration fitting selection is carried out separately.

[0113] The cable penetration fitting selection method in this embodiment saves the man-hours involved in cable penetration fitting selection and improves the design quality. Taking a bulk carrier as an example, the number of cable penetrations on the whole ship is 1300. It is estimated that the average man-hours saved per single calculation is 10 minutes, totaling 220 hours and 27 working days. At the same time, the man-hours for checking need to be included, and a total of 40 working days can be saved, totaling 32,000 yuan in savings. The original design method had calculation errors in the selection, resulting in costs such as on-site construction rework and cable supplement ordering of about 100,000 yuan. A single conventional civilian ship can save a total cost of 130,000 yuan. The amount of cable penetration data on a cruise ship is extremely large, and it is estimated that the total economic savings per single ship is more than 1 million yuan.

[0114] The cable through-hull fitting selection method in this embodiment determines the filling rate of alternative models based on the first parameters of the cable group and the second parameters of the alternative models of the through-hull fitting, and determines the optimal target cable through-hull fitting from the alternative models based on the filling rate of the alternative models, realizing the automation of the cable through-hull fitting selection and improving the efficiency and quality of the selection.

[0115] Embodiment 3

[0116] Please refer to Figure 10 , which is a schematic structural diagram of the cable through-hull fitting selection system in this embodiment. Specifically, as Figure 10 shown, the selection system includes:

[0117] The parameter acquisition module 1 is used to acquire the alternative models of the cable through-hull fitting and the first parameters of the cable group passing through the cable through-hull fitting;

[0118] The filling rate determination module 2 is used to determine the filling rate of the alternative models based on the first parameters and the second parameters of the alternative models; the filling rate is used to characterize the proportion of the total cross-sectional area of the cable group to the cross-sectional area of the cable through-hull fitting;

[0119] The target determination module 3 is used to determine the target cable through-hull fitting from the alternative models based on the filling rate of the alternative models.

[0120] The cable through-hull fitting selection system in this embodiment determines the filling rate of the alternative models based on the first parameters of the cable group and the second parameters of the alternative models of the through-hull fitting, and determines the optimal target cable through-hull fitting from the alternative models based on the filling rate of the alternative models, realizing the automation of the cable through-hull fitting selection and improving the efficiency and quality of the selection,

[0121] Embodiment 4

[0122] As Figure 11 shown, the cable through-hull fitting selection system in this embodiment is a further improvement of Embodiment 1. Specifically:

[0123] In an alternative implementation, the selection system further includes:

[0124] The through-hull fitting knowledge base construction module 4 is used to construct a cable through-hull fitting knowledge base; specifically, cable through-hull fittings are generally divided into two categories: elliptical and circular. As Figure 3 shown, the parameters of the elliptical through-hull fitting include: alternative models, the long side of the inner wall of the elliptical cable through-hull fitting corresponding to the alternative model, and the short side of the inner wall of the elliptical cable through-hull fitting, etc. As Figure 4 shown, the parameters of the circular through-hull fitting include: alternative models, the outer diameter of the circular cable through-hull fitting corresponding to the alternative model, and the wall thickness of the circular cable through-hull fitting, etc.

[0125] The parameter acquisition module 1 is further configured to obtain alternative models of cable penetration parts from the cable penetration part knowledge base.

[0126] In another alternative embodiment, the model selection system further includes:

[0127] A cable knowledge base construction module 5 for constructing a cable knowledge base; specifically, as Figure 5 shown, the parameters of the cable include: cable model, the outer diameter of the cable corresponding to the cable model, etc.

[0128] The parameter acquisition module 1 is further configured to obtain the outer diameter of the cable passing through the cable penetration part from the cable knowledge base; the parameter acquisition module 1 is further configured to determine the first parameter of the cable group based on the outer diameter and quantity of the cable.

[0129] In an alternative embodiment, the filling rate determination module 2 is specifically configured to determine the total cross-sectional area of the cable group based on the first parameter; specifically, the total cross-sectional area of the cable group can be determined by the following formula:

[0130]

[0131] where di is the outer diameter of the i-th cable, in millimeters (mm), and i = 1, 2,..., n.

[0132] The filling rate determination module 2 is specifically configured to determine the cross-sectional area of the alternative model based on the second parameter of the alternative model; specifically, as Figure 6 shown, the cross-sectional area of the elliptical cable penetration part can be determined by the following formula:

[0133] S penetration_T = A * B - ((100 * 100) - (π * 50 * 50));

[0134] where A is the long side of the inner wall of the elliptical cable penetration part, and B is the short side of the inner wall of the elliptical cable penetration part.

[0135] As Figure 7 shown, the cross-sectional area of the circular cable penetration part can be determined by the following formula:

[0136] S penetration_Y = π * ((O.D - 2 * T) / 2) 2 ;

[0137] where O.D is the outer diameter of the outer wall of the circular cable penetration part, and T is the wall thickness of the circular cable penetration part.

[0138] The filling rate determination module 2 is specifically configured to determine the filling rate of the alternative model based on the total cross-sectional area of the cable group and the cross-sectional area of the alternative model.

[0139] In an alternative embodiment, the model selection system further includes:

[0140] Relative cross-sectional area acquisition module 6, used to obtain the relative cross-sectional area of the cable entry member; the relative cross-sectional area is used to indicate the ratio of the cross-sectional area of the cable entry member used for passing the cable to the cross-sectional area;

[0141] The filling rate determination module 2 is specifically used to determine the filling rate of the alternative model based on the total cross-sectional area of the cable group, the cross-sectional area of the alternative model and the relative cross-sectional area. Specifically, the cable penetration rate can be determined by the following formula:

[0142] or

[0143] Among them, δ is the penetration coefficient, which can be 0.3 to 0.4. For cables with large outer diameter, penetration parts with a larger coefficient can be selected, and for cables with small outer diameter, penetration parts with a smaller coefficient can be selected.

[0144] Transposition transformation calculation: The filling rate μ relative to the cross-sectional area (δ0) can be determined by the following formula z :

[0145]

[0146]

[0147] When δ0 is constant (e.g. δ0 = 0.3), the type of the fixed cabin penetration is elliptical, which must satisfy δ<δ0. When δ increases, the filling rate μ z Increase, cross-sectional area S penetration_T Reduce, accordingly, we can get the minimum cable through the cabin model requirements, while meeting the requirements can save more materials and reduce the difficulty coefficient of structural review. That is, what needs to be obtained is the maximum μ when δ0 is given. z Get the value.

[0148] The following examples are used to demonstrate this. Figure 8 As shown, the input parameters include:

[0149] ① Given a value of δ0, only the integer part before the percentage needs to be filled in;

[0150] ②Cable entry fitting selection (T: elliptical, Y: round);

[0151] ③ List of cables passing through cabins.

[0152] The parameters in the calculation process include:

[0153] ④Summary of total cable cross-sectional area;

[0154] ⑤、⑥ The penetration rate display and the minimum cross-sectional area requirement of the cable entry parts when the cable penetration rate is given;

[0155] ⑦ and ⑧ display the relative cross-sectional area filling rate based on the given cable penetration rate;

[0156] ⑨ Extract the basic information of the list of cables passing through the cabin based on the given cable samples;

[0157] ⑩ Display the usage effect of the alternative cable through-cabin parts.

[0158] The output result display:

[0159] Recommendation for the selection of cable through-cabin parts;

[0160] Display the relative filling rate when selecting the recommended cable through-cabin parts.

[0161] In another example, as Figure 9 shown, the filling rate cannot exceed 100%, so select the model corresponding to the maximum filling rate within 100%.

[0162] In addition, when no suitable model can be selected for the current cable group, split the cable group and then select the cable through-cabin parts separately.

[0163] The method for selecting cable through-cabin parts in this embodiment saves the man-hours involved in the selection of through-cabin parts and improves the involved quality. Taking a bulk carrier as an example, the number of cable penetrations through the cabin of the whole ship is 1300. It is estimated that the average man-hours saved per single calculation is 10 minutes, with a total of 220 hours and 27 working days saved. At the same time, the man-hours for checking need to be included, and a total of 40 working days can be saved, with a total savings of 32,000 yuan. The original design method involved calculation errors in the selection, resulting in costs such as on-site construction rework and cable supplement ordering of about 100,000 yuan. For a single conventional civilian ship, a total cost of 130,000 yuan can be saved. The amount of cable penetration data for a cruise ship is extremely large, and it is estimated that the total economic savings per single ship is more than 1 million yuan.

[0164] The cable through-cabin part selection system of this embodiment determines the filling rate of the alternative models based on the first parameter of the cable group and the second parameter of the alternative models of the through-cabin parts, and determines the best target cable through-cabin part among the alternative models based on the filling rate of the alternative models, realizing the automation of the selection of cable through-cabin parts and improving the efficiency and quality of the selection.
