Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to a method and system for efficient and standardized inspection and quality control of ships. Background Technology

[0002] Quality inspection is involved in every stage of shipbuilding, with numerous inspection items and a large workload. Due to the lack of a standardized inspection system, even for the same type of ship, the types and requirements of inspection items are inconsistent. This forces inspectors to spend a significant amount of time developing inspection checklists for each item before conducting on-site inspections. Furthermore, traditional ship inspection relies primarily on two-dimensional drawings, which fail to provide a clear understanding of the specific shape, inspection areas, and inspection locations of the product being inspected. On-site inspection data can only be recorded on paper and cannot be directly uploaded to a quality management system for data analysis and evaluation. Consequently, the standardization and digitalization of ship inspection lag behind, hindering the optimization of ship process design and the transformation towards intelligent manufacturing. Summary of the Invention

[0003] In view of this, the present invention provides a method and system for efficient and standardized inspection and quality control of ships, in order to solve the problems existing in the above-mentioned background art.

[0004] A method for efficient and standardized inspection and quality control of ships includes the following steps: S1. Construct a ship standard inspection knowledge base, which stores a standard inspection item table and an inspection element list for each inspection item, as well as the association rules between inspection items and inspection elements. S2, based on the actual ship product to be inspected, automatically match the standard inspection item list and inspection element list required for the actual ship product to be inspected from the ship standard inspection knowledge base; S3, based on the standard inspection item list and inspection element list required for actual ship inspection of the actual ship product, define the integrity of the inspection elements of the three-dimensional design model of the actual ship product; S4. Based on the completed 3D design model and its design drawings for the defined inspection elements, and combined with the association rules between inspection items and inspection elements, automatically generate an inspection item data package. S5. Based on the inspection item data package, conduct on-site inspection of the actual ship products, analyze and evaluate the actual inspection data, automatically close the loop for inspection items that meet the quality requirements, analyze the inspection elements of non-conforming items for inspection items that do not meet the quality requirements, and backtrack to the process design or ship construction stage for optimization, and then repeat steps S2-S5 until all inspection items meet the quality requirements.

[0005] Preferably, the specific steps for constructing the ship standard inspection knowledge base in step S1 are as follows: The types of inspection items throughout the entire shipbuilding process, the inspection requirements for each inspection item, and the inspection elements for each inspection item are determined. Based on the various inspection items and their inspection elements throughout the entire shipbuilding process, standard inspection item tables and inspection element lists for each inspection item are developed. Based on the standard inspection item table and inspection element list for each inspection item, a ship standard inspection knowledge base is constructed.

[0006] Preferably, the ship standard inspection knowledge base stores a standard inspection item table and an inspection element list for all inspection items involved in the entire construction process of various ship types.

[0007] Preferably, the specific steps in step S3 for defining the integrity of inspection elements in the three-dimensional design model of the actual ship product based on the standard inspection item list and inspection element list required for actual ship product inspection are as follows: Based on a standard inspection item list required for actual ship inspection of actual ship products, rotate the 3D design model to display the model position of the inspection items. Based on the inspection element list corresponding to the current inspection item, check whether all inspection elements in the inspection element list have been defined in the 3D design model. If some inspection elements in the inspection element list are missing in the 3D design model, then define the missing inspection elements in the 3D design model. Repeat the above steps to define the integrity of all inspection elements for the 3D design model.

[0008] Preferably, the inspection information extracted from the three-dimensional design model and its design drawings that have completed the definition of inspection elements includes inspection elements, inspection basis, three-dimensional design model, and design drawings of inspection items.

[0009] The specific steps in step S4 to automatically generate an inspection item data package based on the completed 3D design model and its design drawings, combined with the association rules between inspection items and inspection elements, are as follows: Based on the association rules between inspection items and inspection elements stored in the ship standard inspection knowledge base, obtain the inspection item name and inspection item type corresponding to each inspection element in the three-dimensional design model where the inspection element definition has been completed; Extract all inspection criteria and defined inspection elements from the 3D design model where inspection element definitions have been completed. Then, combine the inspection elements belonging to the same inspection item with their corresponding inspection item name, inspection item type, inspection criteria, 3D design model, inspection item design drawings, and on-site inspection information to generate an inspection item data package.

[0010] Preferably, if all inspection elements in the 3D design model that has completed the definition of inspection elements involve multiple inspection items, then each inspection item will generate a corresponding inspection item data package.

[0011] A high-efficiency, standardized inspection quality control system for ships includes an inspection text generation module, a standard inspection database, an inspection text matching module, an inspection data packet generation module, a data packet sending and receiving module, and a quality assessment module. The inspection text generation module is used to collect and statistically analyze the types of inspection items and the inspection requirements of each inspection item throughout the entire shipbuilding process to determine the inspection elements of each inspection item. Based on the various inspection items and their inspection elements throughout the entire shipbuilding process, it also develops a standard inspection item table and an inspection element list for each inspection item. The standard inspection database is used to store the standard inspection item table and inspection element list for each inspection item, as well as the association rules between inspection items and inspection elements; The inspection text matching module is used to automatically match the standard inspection item table and inspection element list required for the actual ship product to be inspected from the ship standard inspection knowledge base according to the ship type of the actual ship product to be inspected, and transmit the matched standard inspection item table and inspection element list to the inspection data package generation module. The inspection data packet generation module is used to define the integrity of inspection elements in the three-dimensional design model of the actual ship product according to the received standard inspection item table and inspection element list, and automatically generate inspection item data packets based on the three-dimensional design model and its design drawings with completed inspection element definitions, combined with the association rules between the inspection items and inspection elements, and transmit the generated inspection item data packets to the data packet sending and receiving module. The data packet sending and receiving module is used to transmit the received inspection item data packet to the mobile terminal, and can also receive the inspection item data packet with added on-site inspection information from the mobile terminal and transmit the inspection item data packet to the quality assessment module. The quality assessment module is used to assess the quality of inspection data with added on-site inspection information in order to determine whether the inspection items meet the quality requirements.

[0012] Preferably, the on-site inspection information includes measured data, inspection tools, inspection personnel, and inspection date.

[0013] The beneficial effects of this invention are: 1. This invention constructs a ship standard inspection knowledge base. Based on the actual ship product to be inspected, it automatically matches the standard inspection item list and inspection element list required for the actual ship product to be inspected from the ship standard inspection knowledge base. Based on the standard inspection item list and inspection element list required for the actual ship inspection, it defines the integrity of the inspection elements on a three-dimensional design model. This ensures that design information, process information, and inspection information are all defined on the same three-dimensional model, unifying the ship data source and realizing the interoperability of design data. Then, based on the three-dimensional design model and design drawings with completed inspection element definitions, and combined with the association rules between inspection items and inspection elements, it automatically generates an inspection item data package, forming a standardized system for ship inspection. This significantly shortens the preparation cycle for ship inspection and improves inspection efficiency and standardization level.

[0014] 2. This invention automatically generates an inspection item data package based on the three-dimensional design model and its design drawings with completed inspection element definitions, combined with the association rules between inspection items and inspection elements. The inspection item data package is then sent to a handheld terminal. Inspectors can use the handheld terminal to inspect and view the three-dimensional design model, inspection items, and elements of the ship products to be inspected at any time. At the same time, on-site inspection information can be written into the inspection item data package and uploaded to the quality control system for analysis and evaluation. This not only changes the traditional two-dimensional drawing inspection mode, but also realizes the backtracking and application of data, supporting the iterative optimization of ship design and construction.

[0015] 3. This invention is a standardized inspection method applicable to different ship products and different inspection items. It also standardizes the entire quality inspection process, including inspection classification, tool application, and data recording, and realizes the digitalization of the inspection process.

Obviously, the drawings described below are only some embodiments of the present invention.

[0017] Figure 1 This is a flowchart of the present invention. Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0019] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The singular forms “a,” “the,” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0020] To better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings.

[0021] This invention provides a method for efficient and standardized inspection and quality control of ships, which specifically includes the following steps: S1. Construct a ship standard inspection knowledge base, which stores a standard inspection item table and an inspection element list for each inspection item, as well as the association rules between inspection items and inspection elements.

[0022] Specifically, the steps for constructing a ship standard inspection knowledge base are as follows: First, we statistically analyze the types of inspection items throughout the entire shipbuilding process, the inspection requirements for each inspection item, determine the inspection elements for each inspection item, and establish the association rules between inspection items and inspection elements. Based on the various inspection items and their inspection elements throughout the entire shipbuilding process, standard inspection item tables and inspection element lists for each inspection item are developed. Based on the above steps, a standard inspection item table and inspection element list for all inspection items involved in the entire construction process of various ship types can be obtained. The standard inspection item table and inspection element list for all inspection items, as well as the association rules between inspection items and inspection elements, are stored in the database to obtain a ship standard inspection knowledge base.

[0023] The standard test item table records all the information about the test items, such as the test item type and test item name.

[0024] The inspection element list contains all the inspection elements for the inspection item, such as various inspection indicators.

[0025] S2, based on the actual ship product to be inspected, automatically match the standard inspection item list and inspection element list required for the actual ship product to be inspected from the ship standard inspection knowledge base.

[0026] The actual ship product can be the structural form of any construction stage of a ship type, such as a section, a whole section, a half-ship, or a complete ship.

[0027] When automatically matching the standard inspection item list and inspection element list required for actual ship inspection of the actual ship product, based on the ship type of the actual ship product to be inspected, all inspection items required for actual inspection of the same ship product under that ship type are found from the ship standard inspection knowledge base, and the standard inspection item list and inspection element list corresponding to these inspection items are obtained.

[0028] There are multiple standard inspection item tables required for the actual ship products to undergo on-site inspection, and each standard inspection item table corresponds to a list of inspection elements.

[0029] S3, based on the standard inspection item list and inspection element list required for actual ship inspection of the actual ship product, define the integrity of inspection elements for the three-dimensional design model of the actual ship product.

[0030] Specifically, firstly, based on a standard inspection item list required for actual ship inspection of the actual ship product, the three-dimensional design model is rotated to display the model position of the inspection item; Based on the inspection element list corresponding to the current inspection item, check whether all inspection elements in the inspection element list have been defined in the 3D design model. If some inspection elements in the inspection element list are missing in the 3D design model, then define the missing inspection elements in the 3D design model. Repeat the above steps to define the integrity of all inspection elements for the 3D design model.

[0031] Define the integrity of inspection elements for all inspection items in the 3D design model, which may include the integrity of inspection elements for all possible inspection items across all disciplines such as hull, electromechanical, painting, and welding.

[0032] S4 automatically generates an inspection item data package based on the completed 3D design model and its design drawings, combined with the association rules between inspection items and inspection elements.

[0033] Specifically, firstly, based on the association rules between inspection items and inspection elements stored in the ship standard inspection knowledge base, the inspection item name and inspection item type corresponding to each inspection element in the three-dimensional design model where the inspection element definition has been completed are obtained; Extract all inspection criteria and defined inspection elements from the 3D design model where inspection element definitions have been completed. Then, combine the inspection elements belonging to the same inspection item with their corresponding inspection item name, inspection item type, inspection criteria, 3D design model, inspection item design drawings, and on-site inspection information to generate an inspection item data package.

[0034] If all inspection elements in the 3D design model with completed inspection element definitions involve multiple inspection items, then a corresponding inspection item data package will be generated for each inspection item. For example, if all inspection elements in the 3D design model with completed inspection element definitions involve three inspection items: hull, painting, and welding, then three inspection item data packages will be generated for each of these three inspection items. Each inspection item data package includes the inspection basis for the inspection item, all inspection elements for the inspection item, the name of the inspection item, the type of the inspection item, the 3D design model of the actual ship product, the design drawings for the inspection item, the on-site inspection information for the inspection item, and the inspection standard association query for the inspection item, etc.

[0035] When generating the inspection project data package, the field containing the on-site inspection information is a reserved field. After the on-site inspection is completed, the actual inspection data will be dynamically written into this field.

[0036] The inspection elements are inspection indicators, which are the precision, quality, and other indicator data corresponding to specific inspection parts, and there shall be no less than one inspection indicator.

[0037] The inspection basis refers to the inspection indicators for this inspection item, such as Chinese shipbuilding quality standards and classification society specifications.

[0038] The name of the test item is the specific name of the single item to be tested.

[0039] The inspection items are classified as external inspection and internal inspection. External inspection involves third parties such as ship owners and ship inspection agencies, while internal inspection is an inspection organized internally by the shipyard.

[0040] The 3D design model is a rotatable and clickable 3D model. Specific inspection parts can be viewed in the 3D design model. Clicking on an inspection part in the 3D model will highlight its corresponding inspection index window, reminding the inspection personnel to check it.

[0041] The design drawings and inspection standards for the inspection items are the corresponding process drawings and inspection standards documents, which can be viewed by the inspection personnel.

[0042] The on-site inspection information includes measured data, inspection tools, inspection personnel, and inspection date. Measured data refers to the actual data of the inspection items obtained by the inspection personnel after taking certain inspection measures, and there must be at least one measured data point; inspection tools are the tools required for this inspection item, such as a total station; inspection personnel are the specific personnel participating in this inspection; and the inspection date is the specific date of this inspection.

[0043] S5: Based on the inspection item data package, conduct on-site inspection of the actual ship products and write the measured data, inspection tools, inspection personnel, and inspection date into the inspection item data package. The system analyzes and evaluates the actual inspection data. Inspection items that meet the quality requirements are automatically closed-loop. For inspection items that do not meet the quality requirements, analyze the inspection elements of their non-conformities and backtrack to the process design or ship construction stage for optimization. Then repeat steps S2-S5 until all inspection items meet the quality requirements.

[0044] This invention also provides a high-efficiency standardized inspection quality control system for ships, comprising an inspection text generation module, a standard inspection database, an inspection text matching module, an inspection data packet generation module, a data packet sending and receiving module, and a quality assessment module.

[0045] The inspection text generation module is used to collect and statistically analyze the types of inspection items and the inspection requirements of each inspection item throughout the entire shipbuilding process to determine the inspection elements of each inspection item. Based on the various inspection items and their inspection elements throughout the entire shipbuilding process, it formulates a standard inspection item table and an inspection element list for each inspection item.

[0046] The standard inspection database is used to store the standard inspection item table and inspection element list for each inspection item, as well as the association rules between inspection items and inspection elements.

[0047] The inspection text matching module is used to automatically match the standard inspection item table and inspection element list required for the actual ship product to be inspected from the ship standard inspection knowledge base according to the ship type of the actual ship product to be inspected, and transmit the matched standard inspection item table and inspection element list to the inspection data package generation module.

[0048] The inspection data packet generation module is used to define the integrity of inspection elements in the three-dimensional design model of the actual ship product according to the received standard inspection item table and inspection element list, and automatically generate inspection item data packets based on the three-dimensional design model and its design drawings with completed inspection element definitions, combined with the association rules between the inspection items and inspection elements, and transmit the generated inspection item data packets to the data packet sending and receiving module.

[0049] The data packet sending and receiving module is used to transmit the inspection item data packet received from the inspection data packet generation module to the mobile terminal, and can also receive the inspection item data packet with added on-site inspection information from the mobile terminal and transmit the inspection item data packet to the quality assessment module.

[0050] The quality assessment module is used to assess the quality of inspection data with added on-site inspection information in order to determine whether the inspection items meet the quality requirements.

[0051] It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
