Description

TECHNICAL FIELD

[0002] The laying and installation of cables is one of the key links in shipbuilding operations. Before the laying and installation of cables in the shipbuilding process, the length needs to be calculated. The length of the cables estimated by manual calculation usually has a certain margin. The cable margin is a certain length of cable that is additionally reserved during the cable laying process. The cable margin needs to be reasonably set considering factors such as cable line adjustment, bending, and joint making. The calculation of the length of cables throughout the ship requires a large amount of human resources to estimate. Considering that the estimation is influenced by too many external factors, the accuracy of manual estimation is usually low. When the calculated cable margin is too long, it is easy to cause a large amount of waste of cables, increasing the manufacturing cost. When the calculated cable margin is too short, it increases the risk of cable scrap. In addition, the cable laying path layout needs to be secondarily decomposed and laid out on site, resulting in low production efficiency.

[0026] This embodiment provides a method for installing cables on ships, applied during the shipbuilding process to tasks such as cable layout, laying, and wiring. (Refer to...) Figure 1 The ship cable installation method of this embodiment includes steps S1 to S6, specifically including: S1. Establish a cable arrangement model for the ship and generate cable layout drawings; S2. Calculate the theoretical cable length using the cable length calculation formula based on the cable sorting model; S3. Perform cable laying operations based on cable layout drawings; S4. Perform cable cutting and splicing operations, and record the cut length of the cable in real time to obtain the actual length of the cable; S5. Update the cutting allowance compensation coefficient in the cable length calculation formula according to the actual length of the cable and the theoretical length of the cable; S6. Based on the updated cable length calculation formula, recalculate the theoretical cable length and proceed with the next cable laying operation.

[0027] This method establishes a cable sequencing model, enabling real-time access to the latest cable layout drawings. This ensures that the cable routing on the cable trays after laying aligns with the layout drawings. By establishing a cable length calculation formula, the theoretical cable length can be calculated quickly and accurately using digital methods, improving construction efficiency and the accuracy of cable layout length calculations, while reducing labor costs. Furthermore, by combining on-site construction data during construction, the actual cable length can be accurately calculated. By comparing this with the theoretical length, the cutting allowance compensation coefficient in the cable length calculation formula is updated, making the calculated theoretical cable length more closely aligned with reality. When laying cables on another vessel, deviations in cable allowance can be reduced or eliminated, thereby reducing or eliminating the need for secondary cutting of cables by construction personnel. This achieves zero-excess cable wiring, avoiding resource waste due to excessively long cables or scrap due to excessively short cables, effectively saving construction costs.

[0028] In step S1, the steps of establishing a cable arrangement model for the ship and generating cable layout drawings may include: compiling a cable arrangement specification to construct a cable arrangement module; using the cable arrangement module to establish a cable arrangement model in the hull model; and generating cable layout drawings based on the cable arrangement model.

[0029] This system utilizes digital AI technology to assist in building a cable sorting module. This module includes cable sorting software that, combined with a ship model, automatically constructs a cable sorting model. The cable sorting specifications define the rules for cable laying and arrangement, including principles such as finding the shortest optimal path between two points and avoiding detours. The cable sorting model must be laid out in the ship model according to these specifications. Optionally, the cable layout drawings can be 3D drawings. By developing cable sorting specifications and establishing the cable sorting module, the position of each cable on the cable tray corresponds one-to-one with the position in the ship model and the cable layout drawings. This ensures that the position and direction of the cables in the ship model and cable layout drawings are consistent with the direction of the cables laid on the cable trays in the actual site. This avoids length errors caused by differences in the inner and outer diameters of the cables laid on the cable trays. Furthermore, the cable sorting module allows for updating the cable sorting model to obtain the latest version of the cable layout drawings, eliminating the need for secondary decomposition and layout on-site, improving work efficiency and reducing the workload of construction personnel.

[0030] In an optional embodiment, the steps of establishing a cable sequencing model for the ship and generating cable layout drawings further include: obtaining first cable information and inputting it into the cable layout drawings, wherein the first cable information includes at least cable start and end equipment information, cable number information, and cable specification and model information; verifying the first cable information in the cable layout drawings to ensure that the first cable information in the cable layout drawings is consistent with the cable manual. By verifying the first cable information in the cable layout drawings, the cable start and end equipment, cable number, and cable specification and model are kept consistent with the cable manual, avoiding errors in cable sequencing that could lead to excessively short cables being laid on-site.

[0031] In step S2, the step of calculating the theoretical length of the cable using the cable length calculation formula includes: establishing the cable length calculation formula; constructing a length calculation module based on the cable length calculation formula; and automatically calculating the theoretical length of the cable using the length calculation module based on the cable sorting model.

[0032] Specifically, a length calculation module can be built using electronic devices such as computers and mobile terminals, based on the cable length calculation formula. This module contains length calculation software. Cable size parameters are obtained according to a cable sorting model and input into the length calculation software, which automatically calculates the theoretical cable length. AI-assisted development of the cable length calculation software can be used to construct this module.

[0033] In an optional embodiment, in the step of calculating the theoretical cable length using the cable length calculation formula, the theoretical cable length is denoted as L. s Then L s=(L z +2L b +2L w +2L y +C n N)(1+β), where, as referenced Figure 2 and Figure 3 L z L is the total length of the straight section of the cable on the cable tray. b L is the length of the cable entering the junction box. w L is the bending length of the cable entering the junction box. y To allow for the cable stripping length, C n The length of the nth cable in the radial and inner diameter directions at the bend of the cable tray is given. The unit of all the above length parameters is (m). N is the number of bends of the cable. The specific values ​​of each of the above parameters can be obtained by measurement and calculation based on the actual construction conditions. β is the cable cutting allowance compensation coefficient.

[0034] In an optional embodiment, refer to Figure 4 and Figure 5 In the step of calculating the theoretical length of the cable using the cable length calculation formula, the length C of the nth cable in the outer radial and inner diameter directions at the bend in the cable bracket is... n =2π(R-(D1+D2+…+D n-1 ) / 4, where R is the bending radius of the cable on the cable tray, D1, D2, ... D n-1 These are the 1st, 2nd, ... Dth points in the radial direction from the outer diameter to the inner diameter. n-1 The diameter of each cable is in meters (m), and n is a positive integer.

[0035] Specifically, referring to Figure 5 For example, when n is 10, the length C of the 10th cable in the outer radial direction at the bend of the cable tray is... 10 =2π(R-(D1+D2+…+D9) / 4, where D is the diameter of the 10th cable in the radial direction from the outside to the inside. 10 .

[0036] The bending length L of the cable entering the junction box w It can be given by the following formula: Lw=2πr / 4=πr / 2; r is the bending radius of the cable before entering the junction box, in meters (m). The specific value of β can be determined according to the diameter and length of the cable. The larger the diameter of the cable, the larger the value of β, and β is less than 1.

[0037] By establishing a length calculation module, the theoretical length of the cable can be calculated quickly and accurately. Combined with on-site construction data, the actual length of the cable can be calculated precisely, improving work efficiency, reducing the workload of construction personnel, improving the accuracy of cable length calculation results, and saving labor costs.

[0038] In step S3, the steps of performing cable laying operation based on cable layout drawings include: laying the cable to the preset position according to the cable layout drawings and obtaining the second cable information in real time; checking the second cable information with the cable manual and marking the laid cable in the cable manual; wherein, the second cable information includes at least the cable start and end equipment information, cable number information, cable specification signal information and cable length information.

[0039] Specifically, during the cable laying process, the information of the second cable is checked in real time, such as the cable's cross-sectional diameter, length, and the equipment at the cable's start and end points. By checking the cable's relevant information in real time during the laying process, it can be ensured that the construction personnel lay the cable according to the cable layout drawings, so that the cable's route on the cable tray is consistent with the cable layout drawings, avoiding cable length deviations caused by incorrect inner / outer diameter routing on the cable tray. In shipbuilding, the specific cable laying methods can refer to existing technologies, and will not be elaborated upon in this embodiment.

[0040] In an optional embodiment, the step of performing cable laying operation based on cable layout drawings further includes: obtaining third cable information, which includes at least cable number information, cable start and end equipment information, and cable start and end area information; and obtaining the cable laying length based on the third cable information and verifying it against the theoretical cable length.

[0041] Specifically, the cable laying length is the length of the cable during the laying process. The cable laying length is obtained through third-party cable information, such as cable number, starting equipment, starting area, ending equipment, ending area, ending compartment, etc., and is checked against the theoretical cable length in the cable manual to ensure the uniqueness of the cable.

[0042] In step S4, the steps of performing cable cutting and splicing operations and recording the cut length of the cable in real time include: establishing a cutting allowance record table; after completing the cable laying operation, if the cable is determined to be too long before stripping, cutting the cable and filling the cut cable length into the cutting allowance record table; performing cable splicing operations; obtaining and recording fourth cable information, which includes at least cable number information, cable start and end equipment information, cable start and end area information, starting end cutting allowance, and ending end cutting allowance.

[0043] Specifically, during cable cutting and splicing operations, relevant information such as cable number, starting equipment, starting area, starting compartment, starting cutting allowance, ending equipment, ending area, ending compartment, and ending cutting allowance are recorded in real time to facilitate the acquisition of the actual cable length. The actual cable length is the actual length of the cable after the cable cutting and splicing operations are completed.

[0044] The actual length of the cable can be calculated based on the cutting allowance recorded in the cutting allowance record table. Optionally, in step S4, the step of calculating the actual length of the cable may include: obtaining the cutting allowance at the beginning end and the cutting allowance at the end end of the cable; obtaining the total cutting allowance of the cable based on the cutting allowance at the beginning end and the cutting allowance at the end end; and calculating the actual length of the cable based on the total cutting allowance and the theoretical length of the cable.

[0045] Furthermore, the president's remaining allowance is denoted as L. x Let L be the cutting allowance at the starting end and the cutting allowance at the ending end. a and L c Let the theoretical length of the cable be denoted as L. s President's remaining balance L x =L a +L c Actual cable length L d =L s -L x The unit for all the above parameters is (m). The actual length of the cable can also be understood as the length required for cable laying and wiring operations.

[0046] In step S5, based on the calculated actual cable length, the value of the cutting allowance compensation coefficient is re-determined to update the cable length calculation formula, ensuring that the theoretical cable length calculated by the formula matches the actual cable length. When cable laying and installation work is carried out on another vessel, step S6 is executed, and the theoretical cable length is recalculated based on the updated cable length calculation formula. The next cable laying operation is then performed based on the recalculated theoretical cable length.

[0047] When using the method of this embodiment for cable laying and wiring installation, the cable length calculation formula has been optimized several times, allowing the calculated theoretical cable length to better match the actual cable length. Furthermore, during this cable laying and wiring process, the cable length calculation formula was optimized again, enabling the calculated theoretical cable length to more accurately match the actual cable dimensions, thereby reducing cable waste and minimizing or even eliminating the need for secondary cable cutting on-site. Verification using this method for cable installation revealed that after two corrections to the cutting allowance compensation coefficient, the theoretical cable length calculated using the cable length calculation formula is essentially consistent with the actual cable length.

[0048] In summary, this method automatically creates a cable sorting model by establishing a cable sorting module, thereby obtaining the latest cable layout drawings. This ensures that the cable routing on the cable trays after laying is consistent with the cable layout drawings, avoiding the need for secondary on-site layout during laying. By establishing a cable length calculation formula and constructing a length calculation module, the theoretical cable length can be automatically calculated, effectively saving human resource costs and improving work efficiency. By combining on-site construction data to calculate the actual cable length and correcting and updating the cutting allowance compensation coefficient, the theoretical cable length calculated according to the cable length calculation formula can be more closely aligned with the actual cable requirements. This effectively reduces or avoids secondary cutting of cables by construction personnel during wiring, achieving cable wiring without allowance and saving construction costs.

[0049] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Any person skilled in the art can modify, alter, or combine the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
