Description

Technical Field

[0001] The technical field of building a regional design structure tree for a ship piping system, in particular, relates to a method and system for generating a regional design structure tree. Background Art

[0002] In the traditional design mode, the detailed design of the piping system is in the form of 2D CAD, while the production design is based on the lofting and process design of the detailed design. Usually, the information on the 2D drawings of the detailed design is constructed into a 3D model in the production design stage. The traditional process is 2D→3D, and does not involve the conversion of the structure tree. With the in-depth application of 3D technology and the development of innovative technology, some assembly plants have realized the application of 3D models in front-end detailed design. This means that the process has changed from 2D→3D to 3D→3D, which is more in line with the concept of a single model. However, due to the different focuses of the two stages, the functions and composition of the two structure trees are also different. The main task of the detailed design stage is to determine the layout of each system of the entire ship piping system according to the construction contract, technical specifications, etc. According to the function. The production (area) design is based on the extension of the detailed design, providing process information, specific details, digital construction mode, etc. for the production site. Therefore, the presentation of the structure tree based on model design at different stages is different. Detailed design focuses on the integrity of ship systems, functions, and design area contents, and usually organizes detailed design structure tree by design area; while regional design mainly focuses on the scope and stage of construction, so regional design is mostly organized by modules, that is, the stage and space of pipe and outfit installation. Therefore, one structure tree is difficult to meet both needs, and it is necessary to build a structure tree for production (regional) design based on the detailed design structure tree. However, the manual conversion of tens of millions of parts is a huge workload, and there is a risk of omission or repeated conversion, which leads to a significant decrease in regional design efficiency.

[0003] This urgently requires improving the conversion method of the regional structure tree and applying information technology to automatically convert the detailed structure tree into a production (regional) design structure tree, thereby ensuring the efficiency and accuracy of the conversion of the regional design structure tree and achieving the goal of clear design division of labor and rapid delivery. Summary of the invention

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the present application is to provide a method and system for generating a regional design structure tree, so as to improve the conversion efficiency and accuracy of the piping regional design structure tree.

[0005] To achieve the above-mentioned and other related purposes, the present invention provides a method for generating a regional design structure tree, comprising:

[0006] S1. The detailed design designer submits the application for transfer to another stage. The system automatically checks the model. If the check is passed, the application is successfully submitted and the model is frozen.

[0007] S2. The reviewer checks the model for confirmation and approves the application process;

[0008] S3. The system automatically generates corresponding nodes in the regional structure tree according to the type, installation stage attributes and space of the detailed design model, and hangs the model under the node, unfreezes the model, and transfers the authority to the regional design designer;

[0009] S4. In the regional design structure tree, a 3D annotation node is automatically created to generate 3D annotation information;

[0010] S5. If the district design model is changed, the detailed design model will be automatically updated synchronously;

[0011] S6. If the detailed design model needs to be changed, a change application must be submitted. After the application is approved, the model authority is transferred to the detailed design designer;

[0012] S7. According to the changes of the detailed design model, the model and 3D annotation information corresponding to the regional structure tree are synchronously updated.

[0013] In one embodiment of the present invention, the step of automatically checking the model by the system includes: checking whether the design model complies with the design specifications and design standards, whether the model design is complete, and whether the design status meets the standards for the transition stage.

[0014] In one embodiment of the present invention, the specific steps of the reviewer's application approval process include: the reviewer checks the model and confirms that the model design status reaches the regional design status, then the reviewer approves it; if there is a problem with the model design, the application is rejected and the model modification opinions are filled in. The system will automatically send a notification to the detailed designer to modify the model.

[0015] In one embodiment of the present invention, the specific steps of automatically generating corresponding nodes in the regional structure tree according to the type, installation stage attribute and belonging space of the detailed design model include:

[0016] Through spatial interference, the installation area of ​​pipes and equipment parts can be clearly defined;

[0017] After the installation area of ​​pipes and equipment is determined, the installation stage of pipes and equipment is determined;

[0018] After the system divides the pipe and equipment model into installation areas and installation stages, it automatically creates corresponding module nodes in the piping area design structure tree according to the pipe and equipment type;

[0019] After the module node is automatically generated, hang the corresponding model under the module node.

[0020] In one embodiment of the present invention, the specific rules for specifying the installation area to which the pipe and equipment components belong are:

[0021] If the pipes and equipment are completely located in the assembly space of a certain section, the pipes and equipment will be divided into the assembly;

[0022] If the pipes and equipment are completely in the block space, divide the pipes and equipment into the block;

[0023] If the pipes and equipment are located at the junction of two sections, the pipes and equipment will be divided into the space of the total section;

[0024] If the pipes and equipment are located at the junction of two main sections, the pipes and equipment shall be divided into the large main section.

[0025] In one embodiment of the present invention, the specific steps of automatically creating a three-dimensional annotation node and generating three-dimensional annotation information in the regional design structure tree include: when the regional design structure tree is automatically generated, a three-dimensional annotation node will be automatically created under the module node.

[0026] In one embodiment of the present invention, the rules for synchronously updating the detailed model are specifically:

[0027] The reference of the area piping and equipment parts is changed. The reference change includes the change of model features, parameters, and reference attributes. Because the detailed piping and equipment parts model and the area piping and equipment parts model are the same reference, the detailed piping and equipment parts model will be automatically changed synchronously.

[0028] The instance change of the area-designed pipe and equipment parts includes the change of the spatial position and instance attributes of the model. The system will automatically read the instance attributes of the area-designed pipe and equipment parts model, match the detailed pipe and equipment parts model according to the associated ID, and determine whether the spatial position and instance attributes of the two are consistent. If not, the detailed pipe and equipment parts model will be changed to be consistent with the spatial position and instance attributes of the area-designed model;

[0029] When adding a model to a district design, the pipe and equipment model added in the district design structure tree will be identified through comparison, and the model will be automatically added to the detailed design structure tree;

[0030] Deletion of detailed design models will identify redundant pipe and outfitting models in the detailed design structure tree through comparison, and automatically delete the models in the detailed design structure tree.

[0031] In one embodiment of the present invention, if the detailed design model needs to be changed, a change application needs to be submitted. After the application is approved, the specific steps of transferring the model authority to the detailed design designer include: during the design process, if principle modifications are required, the detailed design model needs to be changed. The detailed design designer submits a change application. After the change application is submitted, the system automatically notifies the relevant reviewer for approval. After the approval is passed, the model authority is transferred to the detailed design designer.

[0032] In one embodiment of the present invention, the specific rules for synchronously updating the model corresponding to the regional structure tree are:

[0033] The reference of detailed piping and outfitting is changed. The reference change includes the change of model features, parameters, and reference attributes. Because the detailed piping and outfitting model and the district piping and outfitting model are the same reference, the district piping and outfitting model will be automatically changed synchronously.

[0034] Detailed pipe and equipment instance changes, including changes to the spatial position and instance attributes of the model. The system will automatically read the instance attributes of the zone pipe and equipment model, match the detailed pipe and equipment model according to the associated ID, and determine whether the spatial position and instance attributes of the two are consistent. If not, the zone pipe and equipment model will be changed to be consistent with the spatial position and instance attributes of the detailed model;

[0035] When adding detailed design models, the pipe and equipment models added in the detailed design structure tree will be identified through comparison, and the models will be automatically added in the regional design structure tree;

[0036] Detailed design model deletion will identify redundant pipe and outfitting models in the regional design structure tree through comparison and automatically delete the models in the regional design structure tree.

[0037] In one embodiment of the present invention, the specific rules for synchronously updating the three-dimensional annotation information in the area are:

[0038] If the model features or spatial position are changed, the original associated 3D annotation information will be deleted and the 3D annotation will be automatically performed again;

[0039] When the model is increased, the 3D annotation will automatically generate new part numbers and dimension annotations;

[0040] If the model is deleted, the original associated 3D annotation information, including part number and dimension annotation, will be deleted directly;

[0041] For other changes, such as parameter and property changes, the originally associated 3D annotation information remains unchanged.

[0042] A regional design structure tree generation system includes:

[0043] Phase transfer application module: used to submit model phase transfer application. After submitting the application, the system automatically checks the model design quality. If there is no quality problem, the application is successfully submitted and the relevant reviewer will review and approve it.

[0044] Structure tree conversion module: automatically convert the detailed design structure tree into the regional design structure tree;

[0045] Automatic 3D annotation module: automatic 3D annotation of the pipe and equipment model of the zone, the annotation information mainly includes part number, size, rib position annotation and auxiliary elements;

[0046] Change application module: Submit the change application, and after the relevant reviewer approves it, the detailed design designer can change the detailed design model;

[0047] Change synchronization module: According to the change synchronization rules, the regional design structure tree is automatically synchronized to make the regional model consistent with the detailed design model, and the corresponding 3D annotation information is automatically updated.

[0054] See also Figure 1 The present invention provides a method for generating a regional design structure tree, comprising:

[0055] S1. The detailed design designer submits the application for transfer to another stage. The system automatically checks the model. If the check is passed, the application is successfully submitted and the model is frozen:

[0056] The piping system detailed design designer models the system. After the detailed design model is completed, the designer defines the model installation stage information in the model properties, then selects the model node to be transferred to the stage, and initiates the model transfer application. The system will automatically check the model, mainly to check whether the design model meets the design specifications and standards, whether the model design is complete, and whether the design status meets the stage transfer standards, such as pipeline connectivity, pipeline diameter consistency, pipeline material consistency, attribute integrity, and consistency with equipment interfaces. If the system check passes, the application is submitted successfully, the model is frozen, and enters the reviewer approval process. If there are design quality problems with the model, the system check fails, the application submission fails, and the system notifies the designer to correct the model;

[0057] S2. The reviewer checks the model for confirmation and approves the application process:

[0058] After the detailed designer successfully submits the model transfer application, the system automatically sends a notification to the corresponding reviewer. The reviewer enters the approval process, checks the model, and approves it after confirming that the model design status has reached the regional design status. If there is a problem with the model design, the application will be rejected and the model modification opinions will be filled in. The system will automatically send a notification to the detailed designer to modify the model.

[0059] S3. The system automatically generates corresponding nodes in the regional structure tree according to the type of detailed design model, installation stage attributes and the space to which it belongs, and hangs the model under the node. The model is unfrozen and the authority is transferred to the regional design designer:

[0060] The system automatically generates the piping area design structure tree nodes according to the model of the required stage. The specific steps are as follows:

[0061] 1) The system automatically divides pipes and fittings into installation areas based on the interference between pipes and fittings and space. The rules are as follows:

[0062] If the pipes and equipment are completely located in the assembly space of a certain section, the pipes and equipment will be divided into the assembly;

[0063] If the pipes and equipment are completely in the block space, divide the pipes and equipment into the block;

[0064] If the pipes and equipment are located at the junction of two sections, the pipes and equipment will be divided into the space of the total section;

[0065] If the pipes and equipment are located at the junction of two main sections, the pipes and equipment shall be divided into the main section;

[0066] 2) After the installation area of ​​pipes and equipment is determined, the installation stage of pipes and equipment is determined;

[0067] 3) After the system automatically divides the pipe and equipment model into installation areas and installation stages according to the above rules, the system automatically creates corresponding module nodes in the piping area design structure tree according to the pipe and equipment type;

[0068] 4) After the module node is automatically generated, hang the corresponding model under the module node;

[0069] S4. In the regional design structure tree, a 3D annotation node is automatically created to generate 3D annotation information:

[0070] When the regional design structure tree is automatically generated, a 3D annotation node will be automatically created under the module node;

[0071] S5. If the area design model is changed, the detailed design model will be automatically updated synchronously:

[0072] After the regional structure tree is automatically generated, the regional designer has the model modification authority. If it does not involve principle modification but only production process modification, the regional designer can directly modify the regional model, and the detailed model will be directly changed and automatically updated synchronously by the synchronization module. The detailed pipe and outfit model and the regional pipe and outfit model are the same reference, but different instances. They are associated and matched through instance ID, that is, when the regional structure tree is automatically generated, the system will record the instance ID of the detailed pipe and outfit in the instance attribute of the regional pipe and outfit. The synchronization rules are as follows:

[0073] 1. Change the reference of the area-designed pipe and equipment. The reference change includes the change of model features, parameters, and reference attributes. Since the detailed pipe and equipment model and the area-designed pipe and equipment model are the same reference, the detailed pipe and equipment model will be automatically changed synchronously.

[0074] 2. Changes to the instance of the area-designed pipe and equipment parts include changes to the spatial position and instance attributes of the model. The system will automatically read the instance attributes of the area-designed pipe and equipment parts model, match the detailed pipe and equipment parts model according to the associated ID, and determine whether the spatial positions and instance attributes of the two are consistent. If not, the detailed pipe and equipment parts model will be changed to be consistent with the spatial position and instance attributes of the area-designed model;

[0075] 3. When adding a model to a district design, the pipe and equipment model added in the district design structure tree will be identified through comparison, and the model will be automatically added to the detailed design structure tree;

[0076] 4. Delete the detailed design model. By comparing and identifying the redundant pipe and equipment models in the detailed design structure tree, the model will be automatically deleted in the detailed design structure tree.

[0077] S6. If the detailed design model needs to be changed, a change application must be submitted. After the application is approved, the model authority is transferred to the detailed design designer:

[0078] During the design process, if the principle modification is required, the detailed design model needs to be changed. The detailed design designer submits a change application. After the change application is submitted, the system automatically notifies the relevant reviewer for approval. After approval, the model authority is transferred to the detailed design designer;

[0079] S7. According to the changes of the detailed design model, the model and 3D annotation information corresponding to the regional structure tree are updated synchronously

[0080] 1) After the detailed design designer changes the model, the system automatically synchronizes the model of the regional design structure tree according to the changes of the detailed design model. The detailed design pipe and equipment model and the regional design pipe and equipment model have the same reference but different instances. They are associated and matched through the instance ID. That is, when the regional structure tree is automatically generated, the system will record the instance ID of the detailed design pipe and equipment in the instance attribute of the regional design pipe and equipment. The synchronization rules are as follows:

[0081] 1. Change the reference of detailed pipe and equipment. The reference change includes the change of model features, parameters, and reference attributes. Because the detailed pipe and equipment model and the district pipe and equipment model are the same reference, the district pipe and equipment model will be automatically changed synchronously.

[0082] 2. Changes to the detailed pipe and equipment instance, including changes to the spatial position and instance attributes of the model. The system will automatically read the instance attributes of the zone pipe and equipment model, match the detailed pipe and equipment model according to the associated ID, and determine whether the spatial positions and instance attributes of the two are consistent. If not, the zone pipe and equipment model will be changed to be consistent with the spatial position and instance attributes of the detailed model;

[0083] 3. When adding detailed design models, the pipe and equipment models added in the detailed design structure tree will be identified through comparison, and the models will be automatically added in the regional design structure tree;

[0084] 4. Detailed design model deletion: redundant pipe and equipment models in the regional design structure tree will be identified through comparison, and the models will be automatically deleted in the regional design structure tree;

[0085] 2) Synchronize and update the 3D annotation information of the area according to the changes of the model. The 3D annotation is associated with the regional design model. After the regional design model is synchronized, its associated 3D annotation information will be automatically synchronized. The specific synchronization rules are as follows:

[0086] 1. If the model features or spatial position are changed, the original associated 3D annotation information will be deleted and the 3D annotation will be automatically done again;

[0087] 2. When the model is added, the 3D annotation will automatically generate new part numbers and dimension annotations;

[0088] 3. If the model is deleted, the original associated 3D annotation information, including part number and dimension annotation, will be deleted directly;

[0089] 4. For other changes, such as parameter and attribute changes, the original associated 3D annotation information remains unchanged.

[0090] See also Figure 2 The present invention provides a regional design structure tree generation system comprising:

[0091] Phase transfer application module: used to submit model phase transfer application. After submitting the application, the system automatically checks the model design quality. If there is no quality problem, the application is successfully submitted and the relevant reviewer will review and approve it.

[0095] Change synchronization module: According to the change synchronization rules, the regional design structure tree is automatically synchronized to make the regional model consistent with the detailed design model, and the corresponding 3D annotation information is automatically updated.

[0096] In summary, the present invention effectively reduces the workload of designers in manually converting the regional structure tree, reduces the risk of missing or repeating the conversion model, effectively improves the conversion efficiency of the model, and achieves the purpose of clear division of labor and rapid drawing. Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.
