Description

Technical Field

[0001] This invention belongs to the field of ship digital design technology, specifically relating to an automatic statistical method and system for cable information for MBSE modeling. Background Technology

[0002] In traditional ship engineering design, cable information mainly relies on manual compilation, summarization, classification, and statistics of cable length and weight to finally complete a cable register for a certain part or compartment. This process is inefficient and prone to errors. If the selected cables are changed during the design process, it will also lead to a lot of tedious modification work.

[0003] Currently, MBSE-based design methods are widely used in ship digital design. By fully utilizing MBSE modeling elements and combining them with professional characteristics to develop custom elements and functional modules, work efficiency can be significantly improved. In MBSE, the connection relationships between modules (equipment) can be described through internal module diagrams. Based on this modeling process, the design manages cable information and creates a cable model library using cable elements as the basic unit to achieve cable element reuse. For the connections (i.e., cables) representing the connections between modules (equipment), matching cable elements are selected, and engineering parameters such as cable code, cable length, and whether it is a cable provided with the equipment or a cable passing through a compartment are set. Equipment engineering parameters, such as equipment name, equipment code, equipment location (rib, compartment, deck, hull), etc., are added to the module attributes representing the equipment in the internal module diagram. These parameters can be set by the designer. Visual differences are used to distinguish between connections and modules (equipment) with set and unset engineering parameters to remind users to avoid omissions. Based on the above modeling parameter settings, a custom cable detail plugin can be used to select the corresponding internal module diagram to extract information from the internal module diagram and automatically generate a cable detail table. Cable books can also be generated by exporting them according to templates. Summary of the Invention

[0004] The technical problem to be solved by this invention is to provide an automatic statistical method and system for cable information for MBSE modeling, so as to improve the efficiency and accuracy of engineering design.

[0005] The technical solution adopted by this invention to solve the above-mentioned technical problems is as follows: an automatic statistical method for cable information based on MBSE modeling, comprising the following steps: S1: Create a cable element and set its specific parameters; S2: A cable model library composed of cable elements; S3: Design the internal module diagram to determine the modules, the connections between modules (i.e., cables), and the corresponding engineering parameters; S4: Generate a cable list based on the internal module diagram and export the cable book in template format.

[0006] According to the above scheme, in step S1, the special parameters include brand or model, core wire and cross-sectional area, cable diameter, technical document or standard number, and weight per meter.

[0007] According to the above scheme, in step S2, cable elements are imported into the specified cable library via a CSV file of a specific format.

[0008] According to the above scheme, in step S2, the cable model library includes a power cable library and a communication cable library.

[0009] According to the above scheme, the specific steps in step S3 are as follows: S31: Select a matching cable element from the cable type library as the connection between modules; set the engineering parameters of the cable element; S32: Set the module's engineering parameters; S33: Distinguish between cable elements or modules with and without set engineering parameters by visual differences; add, edit, or delete engineering parameters for cable elements and modules according to engineering design needs.

[0010] Furthermore, in step S31, cable elements from the power cable library are selected for connection between the control unit and the distribution box; cable elements from the communication cable library are selected for connection between the control units; and the transmission type is set for the communication cable.

[0011] According to the above scheme, in step S3, The engineering parameters of cable elements include cable designation, cable length, and whether it is a cable provided with the equipment or a cable passing through a compartment. The module's engineering parameters include the equipment name, equipment code, and the location of the equipment in the rib, compartment, deck, and hull.

[0012] According to the above scheme, the specific steps in step S4 are as follows: The system reads the dedicated parameters of cable elements between modules, the engineering parameters of cable elements, and the engineering parameters of modules from the internal module diagram, generates a cable list corresponding to the specified internal module diagram, and synchronously updates the above parameters and exports the cable book according to the template.

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0026] Example 1 See Figure 1 The specific steps of an automatic cable information statistics method for MBSE modeling are as follows: S1: Create cable element Create cable elements and set their specific parameters, including grade or model, core wire and cross-sectional area, cable diameter, technical document or standard number, and weight per meter.

[0027] S2: Create a cable model library The cable model library is composed of cable elements. The cable model library can be divided into power cable library, communication cable library, etc., according to the characteristics of engineering design.

[0028] Furthermore, it supports importing cable elements into a specified cable library via a CSV file in a specific format. See the attached diagram for the cable model library structure. Figure 2 As shown.

[0029] S3: Design Internal Module Diagram Modeling and design were carried out based on the internal module diagrams used in MBSE work. Further design work was conducted beyond the traditional internal module diagram design, including the following: S31: Select matching cable elements from the cable type library as connections between modules (equipment). For example, select power cable elements to connect control units and distribution boxes, and communication cable elements to connect control units. Set the engineering parameters of the cable elements, including cable code, cable length, and whether it is a built-in cable or a cable passing through a compartment. For MBSE modeling software, a cable element engineering parameter setting dialog box can be designed in the internal module diagram design interface. The cable element engineering parameters are set by right-clicking the cable element to bring up this dialog box. Furthermore, for communication cables, the transmission type can be set, such as CAN bus or Ethernet, to better utilize the internal module diagram to display design information.

[0030] S32: Set module (equipment) engineering parameters, including equipment name, equipment code, and the location of the equipment (rib, compartment, deck, or hull). For MBSE modeling software, the module (equipment) engineering parameter setting dialog box can be designed in the internal module diagram design interface. The module (equipment) engineering parameters are set by right-clicking the module (equipment) to bring up this dialog box.

[0031] Furthermore, the parameters for cabins, decks, and hull sides can be set using the following boxes to standardize input and avoid erroneous information input.

[0032] In this step, connections (cable elements) without engineering parameter settings are marked in red, while those with engineering parameter settings are marked in black, with the cable code noted next to them. This visual difference distinguishes between connections (cable elements) with and without engineering parameter settings, prompting users to avoid omissions. Modules (devices) without engineering parameter settings have red borders, while those with engineering parameter settings have black borders. The set engineering parameters are displayed in the module information, again visually distinguishing between modules (devices) with and without engineering parameter settings, prompting users to avoid omissions. See the attached example of an internal module diagram design. Figure 3 As shown, the red lines and red borders of the modules in the example's internal module diagram indicate that the engineering parameters have not yet been set.

[0033] Furthermore, engineering parameters for cable elements and modules (equipment) can be added according to engineering design requirements.

[0034] S4: Generate a cable list and export the cable register according to the template format. The cable detailing plugin in the MBSE tool is designed to read the parameter information set in step three above in the user-selected internal module diagram. This includes the dedicated parameters of cable elements between modules (equipment), the engineering parameters of the cable elements, and the engineering parameters of the module (equipment). It then generates a cable detailing table corresponding to the specified internal module diagram and can automatically update the modified parameters and export it as a cable booklet. An example of the generated cable detailing table is attached. Figure 4 As shown.

[0035] Furthermore, the user calls the cable detailing plugin in the MBSE tool, selects the internal module diagram as the input to the cable detailing plugin, and then the cable detailing plugin reads the relevant information in the internal module diagram used to generate the cable detailing table.

[0036] Furthermore, users can export the cable details table as a cable book through the cable details plugin. In addition to the cable details table information, the cable book also includes comprehensive cable details information, that is, it automatically classifies cables by cable brand or model, counts the length and weight of each category of cables, and automatically calculates the total weight.

[0037] Furthermore, the format of the exported cable register can be customized according to the engineering design template provided by the user, exporting it as a cable register for engineering design, improving work efficiency and avoiding potential errors from manual statistics. The exported cable register includes a compartment cable list and a comprehensive cable list; see detailed page examples. Figure 5 As shown.

[0038] This embodiment manages cable information by creating a cable model library, using cable elements as the basic unit. In the internal module diagram of MBSE modeling, matching cable elements are selected for the connections between equipment modules. Engineering parameters are set for modules and cable elements in the internal module diagram, and visual differences distinguish between modules and cable elements with and without set engineering parameters. A cable detail plugin is designed; by selecting the corresponding internal module diagram, information is automatically extracted to generate a cable detail table, and a cable booklet is exported according to a template. This achieves the function of improving the efficiency and accuracy of engineering design.

[0039] Example 2 The steps in this embodiment are the same as in Embodiment 1, except that each step is applied to a specific instance. Specifically, it includes the following steps: S1: Create cable element In the MBSE development software, custom elements are developed to create cable elements and set their specific parameters, including grade or model, core wire and cross-sectional area, cable diameter, technical document or standard number, and weight per meter.

[0040] Taking the creation of a communication type cable as an example, create a cable element and fill in the specific parameters: Brand or model: JHRP85 Core wire and cross-sectional area: 10×2×0.6 Cable diameter: 14.1 (mm) Technical document or standard number: GJB1916-1994 Weight per meter: 0.372 Furthermore, you can create categorized libraries such as power cable libraries and communication cable libraries, add the corresponding cables, or import cable elements into a specified cable library using a CSV file in a specific format.

[0041] After this step is completed, the cable line elements for commonly used cables in the project will be created.

[0042] S2: Create a cable model library Based on the design characteristics of the engineering models, the cable model library can be further subdivided into power cable libraries, communication cable libraries, etc. The cable elements created in the first step are then categorized into the corresponding cable libraries. See the structure diagram of the created cable model library. Figure 2 As shown.

[0043] Furthermore, it supports importing cable elements into a specified cable library via a CSV file in a specific format.

[0044] The created cable model library provides unified management of cable elements, enabling "create once, use everywhere".

[0045] S3: Design Internal Module Diagram The following design work will be carried out further in the traditional MBSE internal module diagram design.

[0046] S31: Select a matching cable element from the cable type library as the connection between modules (equipment). For example, select a cable element from the power cable library to connect the control unit and the distribution box, and select a cable element from the communication cable library to connect the control units. Set the engineering parameters of the cable element, including cable code, cable length, and whether it is a cable provided with the equipment or a cable passing through the enclosure. Taking setting engineering parameters for cable elements between equipment as an example, fill in the engineering parameter information: Set the cable code to C1-09, the cable length to 10 meters, and select whether it is a cable provided by the equipment or a cable passing through the cabin (yes or no) via the drop-down box.

[0047] When operating the MBSE modeling software, in the design of the internal module diagram, the cable element is right-clicked to bring up the cable element engineering parameter settings dialog box for configuration. Furthermore, for communication cables, the transmission type can be set, such as CAN bus or Ethernet, to better utilize the internal module diagram to display design information.

[0048] S32: Set module (equipment) engineering parameters, including equipment name, equipment code, and the location of the equipment (rib, compartment, deck, or hull). In MBSE modeling software, during the design of the internal module diagram, right-click on the module (equipment) to bring up the equipment engineering parameter settings dialog box. For example, to set engineering parameters for a module (equipment), fill in the following engineering parameter information: Equipment Name: Control Unit; Equipment Code: RC-01; Equipment Location: 41~42; Compartment: II; Level: Upper; Side: Port.

[0049] During the internal module diagram design process, connections (cable elements) without engineering parameter settings are marked in red, while connections (cable elements) with engineering parameter settings are marked in black, with the cable code noted next to them; the borders of modules (equipment) without engineering parameter settings are shown in red, while the borders of modules (equipment) with engineering parameter settings are shown in black, and the set engineering parameters are displayed in the module information, see appendix. Figure 3 As shown, visual differences are used to distinguish items and prompt users to avoid omissions.

[0050] S4: Generate a cable list and export the cable register according to the template format. In the MBSE tool, design a cable detail plugin and select the internal module diagram from which cable detail information needs to be generated. The main function of the cable detail plugin is to read the information set in step S3 above in the internal module diagram selected by the user, including the special parameters of cable elements between modules (equipment), cable engineering parameters, and module (equipment) engineering parameters, generate a cable detail table for the specified internal module diagram, and can automatically update the above parameter modifications and export it as a cable book.

[0051] After completing step S3, enable the cable details plugin, select the internal module diagram, and the corresponding cable details table will be generated.

[0052] Furthermore, the output can be exported as a cable register according to the engineering design template format. In addition to the cable details list, the cable register also includes comprehensive cable details, automatically classifying cables by cable grade or model, calculating the length and weight of each category, and automatically calculating the total weight. This automatic export and statistical method improves work efficiency and avoids errors that may occur with manual calculations. The exported cable register includes a compartment cable details list and a comprehensive cable details list; see the attached page for a detailed example. Figure 5 As shown.

[0053] This embodiment manages cable elements uniformly through a created cable model library, achieving "create once, use everywhere." Modifications to cable element parameters are automatically synchronized to the internal module diagram and updated in the generated cable details table. The cable register categorizes and statistically analyzes cable information by brand or model, and calculates cable length and weight by category. By fully utilizing MBSE modeling elements and innovative design methods, design efficiency is effectively improved compared to traditional manual cable information statistics.
