Description

Technical Field

[0001] This invention belongs to the fields of ship digital design and factory-institute collaborative design technology, specifically involving a method for three-dimensional region design driven by electrical principles. Background Technology

[0002] Ship design encompasses multiple stages, including conceptual design, schematic design, technical design, construction design, and production design. During the conceptual, schematic, and technical design stages, designers organize the product structure according to professional and systemic dimensions, considering the integrity of the product structure from a systemic and professional perspective, without reflecting construction requirements. The construction design stage, however, needs to consider the assembly plant's construction capabilities, refining the theoretical design to create a regionally feasible assembly plant construction plan.

[0003] During the conceptual design, scheme design, and technical design phases, the electrical engineering team primarily designs and draws all diagrams for the power distribution system, lighting system, demagnetization system, and power supply system based on the design principles of each secondary system. In the construction design phase, the above schematic diagrams need to be further refined, while considering the rationality of the transition from schematic design to three-dimensional layout. The schematic diagrams are used to determine the equipment layout and cable tray division by area, adapting to the regional construction requirements of the final assembly plant and realizing the conversion from schematic design to regional design.

[0004] The trays issued by the electrical department of the final assembly plant mainly include the electrical equipment installation tray list and the cable tray list.

[0005] The principle for dividing the electrical equipment installation tray list in the final assembly plant is as follows: The electrical equipment installation tray list is compiled on a regional deck basis. Within each tray list, items are ordered by compartment, and each compartment is listed according to the order of the electrical schematic diagrams, listing all electrical equipment located in that compartment according to the schematic diagrams of each system. However, since the overall electrical schematic diagrams are compiled by system, equipment in the same schematic diagram may be located in multiple regions, decks, and compartments. Therefore, when compiling the electrical equipment installation tray list, the equipment in the schematic diagram must be broken down by region, deck, and compartment, and each piece of equipment must be assigned to a corresponding tray, and then ordered according to the schematic diagram under the corresponding compartment.

[0006] The cable tray list classification principle at the final assembly plant is as follows: Based on the location of the cable connection's starting and ending equipment, the cable tray list is divided into branch cable tray lists, regional trunk cable tray lists, ship-wide trunk cable tray lists, and demagnetizing cable tray lists. Each cable tray list must specify the ship number, laying area, installation drawing number, tray code, model, specifications, length, starting equipment and its compartment, ending equipment and its compartment, cable route nodes, and isolation level. The cable code, model, specifications, names of the cable's starting and ending equipment, and isolation level should be consistent with the principle. Figure 1 Therefore, the location of each device must be consistent with the location in the schematic diagram and the overall layout diagram of electrical equipment.

[0007] To meet the requirements of the electrical equipment installation tray table and cable tray table in the final assembly plant, it is necessary to find the mapping relationship between the upstream electrical schematic diagram and the downstream electrical installation tray table. This mapping includes two aspects: first, the mapping from the equipment in the schematic diagram to the equipment tray table in the production layout; and second, the mapping from the cable information in the schematic diagram to the cable tray table in the production design. This mapping relationship is also the mapping relationship from schematic design to regional design. Only by finding this mapping relationship can the schematic-driven regional design work of electrical systems be completed in the construction design phase.

[0008] Based on the requirements of the electrical equipment installation tray table and cable tray table, it is necessary to establish a hierarchical structure for electrical equipment assembly and a hierarchical structure for cable assembly. Simultaneously, the equipment and cables in the schematic diagram should be mapped to the corresponding nodes in the assembly structure tree. The equipment in the schematic diagram should be decomposed by region, deck, and compartment, with each piece of equipment assigned to a corresponding compartment-level node, and further subdivided according to the schematic diagram within each compartment. Cables in the schematic diagram are categorized into five types based on the region and deck where the cable connection starts and ends: branch cables, regional trunk cables, main hull trunk cables, superstructure trunk cables, and demagnetized cables. Main hull and superstructure trunk cables can be further subdivided by region: Region 1-Region 2 cables, Region 1-Region 3 cables, Region 1-Region 4 cables, etc. Demagnetized cables can be subdivided into: Demagnetized Zone 1 cables, Demagnetized Zone 2 cables, etc. Each cable in the schematic diagram should be assigned to the cable-level node corresponding to its category and region.

[0009] The process described above, which breaks down each device and cable in the schematic diagram by system and then divides them into assembly level nodes by region, is a one-to-one mapping from the system-based devices and cables in the schematic diagram to the region-based devices and cables in production. This process is extremely tedious, involves a large amount of data, is time-consuming, and has a high error rate. Therefore, it is necessary to study a method for rapidly generating an electrical assembly hierarchy structure organized by region dimension from a two-dimensional schematic diagram. Furthermore, if three-dimensional devices and cables can be rapidly generated simultaneously while generating the region-based electrical assembly hierarchy structure, and a preliminary arrangement of the three-dimensional devices can be performed, it will greatly save the time required for device placement.

[0010] In a two-dimensional schematic diagram, the equipment and cables are drawn on a two-dimensional platform, while the three-dimensional equipment and cables reside on a three-dimensional platform. The two platforms lack a connecting bridge. The two-dimensional schematic diagram is completed by the schematic designer, and the three-dimensional design is completed by the 3D designer. Once the two-dimensional diagram is modified, the 3D designer is unaware or insufficiently aware, requiring repeated checks. With frequent iterative modifications to the two-dimensional schematic diagram, ensuring consistency between the three-dimensional equipment and cables and the two-dimensional diagram in terms of coding, basic attributes, and positional attributes is crucial. Manual methods are inevitably labor-intensive, time-consuming, and prone to errors. Therefore, a method for quickly verifying the consistency between the three-dimensional equipment and cables and the two-dimensional schematic diagram is needed.

[0011] The 3D design platform has two tree structures: the Electrical Assembly Tree and the General Assembly Tree. These two trees have different functions. The Electrical Assembly Tree, for 3D cable routing, must ensure the completeness and integrity of the connecting equipment. The General Assembly Tree, on the other hand, must ensure the completeness and integrity of all equipment for interference checks, overall balancing, and drawing generation. Due to the different order of equipment placement, large and power equipment must be placed and participate in interference checks during the schematic and technical design phases, while small electrical seals are placed at the end of the construction design phase. This results in some equipment (small electrical seals) being placed in the Electrical Assembly Tree and others (large and power equipment) being placed in the General Assembly Tree before 3D cable routing. Equipment in the Electrical Assembly Tree needs to be placed under the General Assembly Tree for interference checks and drawing generation, and connecting equipment in the General Assembly Tree needs to be placed under the Electrical Assembly Tree for 3D cable routing. Since equipment must exist in both the Electrical Assembly Tree and the General Assembly Tree simultaneously, it is essential to ensure that the assembly nodes, placement positions, and attributes of the same equipment are completely consistent in both trees. When equipment is frequently iterated and modified, ensuring consistency between the equipment in the electrical assembly tree and the equipment in the general assembly tree in terms of coding, basic attributes, and location attributes is crucial. Manual methods are inevitably labor-intensive, time-consuming, and prone to errors. Therefore, it is necessary to research a method that can quickly verify the consistency between the equipment in the electrical assembly tree and the general assembly tree. Summary of the Invention

[0028] S33: Analyze all equipment in the two-dimensional cable book, and based on the equipment matching results after equipment consistency verification in the two assembly trees, as well as the attribute information and location area information of the equipment in the two-dimensional cable book, automatically create equipment level nodes in the general assembly tree and electrical assembly tree respectively.

[0029] S34: Analyze all cables in the two-dimensional cable register, list all cable details, adjust the order of cable start and end equipment according to the assembly plant's requirements for cable start and end equipment definition; determine the cable category and the area it crosses based on the cable's start and end equipment areas, and automatically create cable hierarchy nodes and cables.

[0030] Furthermore, in step S33, the specific steps are as follows:

[0031] S331: Based on the equipment attribute information in the two-dimensional cable book, automatically generate the assembly tree equipment assembly hierarchy structure in sequence, including product, section, electrical equipment, deck, compartment, schematic diagram name, equipment name, and equipment type code;

[0032] S332: Based on the attribute information of the equipment in the two-dimensional cable book, automatically generate an electrical assembly tree equipment assembly hierarchy structure that includes the power connection equipment, area, deck, compartment, schematic name, equipment name, and equipment type code.

[0033] Furthermore, in step S34, the specific steps are as follows:

[0034] S341: The assembly plant requires the cables to be laid out in three-dimensional cabling from the bow to the stern, from the superstructure to the main hull, and from the upper deck to the lower deck; adjust the sequence of the cable start and end devices according to this requirement.

[0035] S342: Based on the location of the starting and ending equipment of the cable connection and the deck, cables are classified into multiple categories, including branch cables, regional trunk cables, main hull trunk cables, superstructure trunk cables, and demagnetizing cables; main hull trunk cables and superstructure trunk cables are further classified according to the areas they span, such as Area 1-Area 2 cables, Area 1-Area 3 cables, Area 1-Area 4 cables, ...

[0042] The beneficial effects of this invention are as follows:

[0043] 1. This invention is based on the concept of driving three-dimensional physical model design from two-dimensional principles. It converts two-dimensional electrical schematic diagrams into cable books, and rapidly generates and arranges three-dimensional regional electrical assembly hierarchical structures and three-dimensional models organized by region dimension. Based on the assembly rules of the cable books and regional designs, assembly tree building rules are set to determine the regions where equipment and cables are located or cross. The two-dimensional equipment and cables are mapped to the three-dimensional assembly structure based on region dimension, and three-dimensional equipment and cables are automatically generated. This achieves rapid conversion from schematic design to regional design, significantly shortening the design cycle.

[0044] 2. This invention uses cable books as a single data source, mapping three-dimensional equipment and cables one-to-one with two-dimensional schematic equipment and cables, ensuring consistency between two-dimensional and three-dimensional systems and improving design accuracy.

[0057] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0058] See Figure 1 An embodiment of the present invention provides a method for electrical principle-driven three-dimensional region design, comprising the following steps:

[0059] S1: Data Preparation; Based on the cable book template, output the 2D electrical schematic diagram as a 2D cable book. The 2D cable book contains information about the schematic equipment and cables, including equipment type codes, unique equipment codes, and cable numbers, which are key attribute information linked to 3D functionality. The location and area information of the equipment and cables are crucial from schematic design to area design. To ensure the accuracy of 3D cable assembly nodes, 3D cable generation, and 3D cable routing requirements, the cable book requires a large amount of attribute information. The cable book template is as follows: Figure 2 As shown.

[0060] In addition, a cable base table containing basic cable parameter information, a 3D model library, and an equipment library list are required. Based on the hierarchical node creation rules, the first two levels of the electrical assembly tree and the general assembly tree are initially created. Cable product data from various cable manufacturers are collected to establish a cable base table containing parameter information for different cable models and specifications. Equipment 3D modeling is completed and added to the library, and then registered in the equipment library list. The equipment library list is a table for manually registering and managing equipment status, used for quickly searching for already added 3D models. The equipment library list and the cable register are linked through equipment type codes.

[0061] S2: Quickly verify the consistency between the electrical assembly tree and the general assembly tree; due to inconsistencies in the equipment between the electrical assembly tree and the general assembly tree, a quick consistency verification is required. Analyze the cable register, list all connecting equipment details, and compare the equipment details with the three-dimensional equipment in the electrical assembly tree and the general assembly tree for consistency verification, forming equipment matching results; the verification rules are as follows:

[0062] Traverse the entire electrical assembly tree. If the device is not found, traverse the entire general assembly tree. If the device is still not found, generate a device-level node in both assembly trees, generate the device and pre-place it in the electrical assembly tree, and then reference the parent node of the device to the general assembly tree.

[0063] Traverse the entire electrical assembly tree. If the device is not found, traverse the entire general assembly tree. If the device is found, generate a device-level node in the electrical assembly tree and reference the device parent node in the general assembly tree to the electrical assembly tree.

[0064] Traverse the entire electrical assembly tree. If the device is found, then traverse the entire general assembly tree. If the device is found, then do not generate the device.

[0065] Traverse the entire electrical assembly tree. If the device is found, then traverse the entire general assembly tree. If the device is not found, generate a device-level node in the general assembly tree and reference the parent node of the device in the electrical assembly tree to the general assembly tree.

[0066] Verify the consistency of equipment level nodes, attributes, and locations under the two assembly trees, and synchronize them to be consistent. The consistency verification process between the electrical assembly tree and the general assembly tree is as follows: Figure 3 As shown.

[0067] S3: Automatically generate assembly level nodes; the electrical equipment assembly level structure and cable assembly level structure under the general assembly tree and electrical assembly tree must meet the division requirements of the electrical equipment installation tray table and cable tray table of the general assembly plant, that is, organized according to spatial dimensions.

[0068] Create equipment level nodes in the final assembly tree. The equipment in the final assembly tree contains 8 level nodes, and each level node has corresponding naming rules. The final assembly tree is designed with construction design in mind and is delivered to the final assembly plant. This product structure tree is organized according to spatial dimensions and delivered to the final assembly plant in the form of data packages based on the design plan and model maturity.

[0069] Create the physical layer nodes of the electrical assembly tree. The electrical assembly tree contains 6-8 layers of nodes, each with its own naming rules. The physical layer of the electrical assembly tree is designed for construction design and 3D cable routing, and is intended for delivery to the final assembly plant. This product structure tree is organized according to the spatial dimension of regions. In addition to equipment, the electrical assembly tree also needs to classify cables according to their respective regions or the regions they cross.

[0070] Analyze all equipment in the cable register, and based on the equipment matching results after the consistency check of the two assembly trees, as well as the attribute information and location area information of the equipment in the cable register, automatically create equipment-level nodes in the general assembly tree and electrical assembly tree respectively.

[0071] The equipment assembly hierarchy in the final assembly tree is automatically generated based on the equipment attribute information in the cable register: Product → Final Assembly → Electrical Equipment → Deck → Cabin → Schematic Name → Equipment Name → Equipment Type Code. Figure 4 As shown.

[0072] The equipment assembly hierarchy of the electrical assembly tree is automatically generated based on the equipment attribute information in the cable book: main section, deck, compartment, schematic name, equipment name, etc. The hierarchy structure is: electrical assembly tree → power connection equipment → area → deck → compartment → schematic name → equipment name → equipment type code.

[0073] Analyze all cables in the cable register, list all cable details, and adjust the order of cable start and end devices according to the assembly plant's requirements for cable start and end device definitions. Determine the cable category and the area it crosses based on the cable's start and end device areas, and automatically create cable hierarchy nodes and cables.

[0074] The cable assembly hierarchy of the electrical assembly tree is generated based on the cable start and end equipment location attributes in the cable register, etc. The hierarchy structure is: electrical assembly tree → cable → region / backbone cable → cable classification (by region) → regions crossed by the cable (cross-region cable) → cable number.

[0075] In schematic design, cables are undirected, and the order of cable start and end devices is not required; cables can run from A to B or from B to A. However, the assembly plant has directional requirements for cables in three-dimensional cabling: cables should run from bow to stern, from superstructure to main hull, and from upper deck to lower deck. Based on this requirement, the order of cable start and end devices must be adjusted.

[0076] Cables are categorized into five types based on the location of the equipment at the beginning and end of the cable connection, and the deck: branch cables, regional trunk cables, main hull trunk cables, superstructure trunk cables, and demagnetizing cables. Main hull and superstructure trunk cables can be further classified according to the areas they span: Area 1-Area 2 cables, Area 1-Area 3 cables, Area 1-Area 4 cables, and so on. Demagnetizing cables can be classified as: Demagnetizing Zone 1 cables, Demagnetizing Zone 2 cables, and so on. Each cable in the schematic diagram is assigned to the corresponding category and area's cable hierarchy node.

[0077] Electrical assembly tree physical end assembly level such as Figure 5 As shown, the cable start and end devices are defined as follows: Figure 6 As shown in the table. Cables are classified by region as follows: Figure 7 As shown.

[0078] S4: Automatically generates 3D equipment and pre-arranges it; it searches for and reads the equipment's classification code from the cable register, then searches for the equipment's unique 3D model code from the equipment library list based on the classification code. Based on this unique code, it automatically reads the equipment's 3D model from the equipment library and arranges it at the ship's coordinate system origin; specifically, it searches for the compartment number where the equipment is located from the cable register, then searches for the compartment's SAO model (Simplified Space Aspect Model, a spatial model composed of various surfaces such as the ship's outer plating, deck surfaces, and compartment bulkheads, which can be used for preliminary equipment arrangement), reads the compartment's geometric center coordinates, and automatically arranges the equipment's 3D model at the compartment's geometric center. This method allows for the simultaneous arrangement of all equipment on a single section or schematic diagram. Figure 8 , Figure 9 As shown.

[0079] S5: Automatically assigns attribute information to 3D devices and cables; analyzes the codes, basic attributes, and location attributes of 2D devices and cables in the cable register and equipment library, and assigns them to 3D devices and cables. For example... Figure 10 As shown.

[0080] The basic attributes of two-dimensional equipment should include equipment code, classification code, name, model, etc.; the installation attributes of two-dimensional equipment should include the system code to which the equipment belongs, the area code to which the equipment belongs, the room number or siding number to which the equipment belongs, the wiring port number of the equipment, and the cable code to which the equipment is connected.

[0081] The basic attributes of a two-dimensional cable include cable code, model, specifications, diameter, linear density, etc.; the installation attributes of a two-dimensional cable include the system diagram number to which the cable belongs, the area code to which the cable belongs, the codes of the starting and ending devices of the cable connection, and the numbers of the starting and ending device ports of the cable connection.

[0082] S6: Quickly verify the consistency of 2D and 3D systems; verify the consistency of various attribute information of 2D equipment, 2D cables and electrical assembly trees in the 2D cable register, and 3D equipment and 3D cables in the general assembly tree, providing prompts and corrections for inconsistencies. Prompts are provided for the following three situations: missing 3D equipment or cables, incorrect assembly level nodes, and inconsistent 2D and 3D attributes. The system automatically supplements missing equipment, cables and their level nodes according to the prompts, corrects incorrect level nodes, and modifies incorrect attributes. This method can be used for batch and rapid verification of 2D and 3D consistency. Figure 11 As shown.
