BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Figure 1 is a schematic diagram of a management template in one embodiment of the present invention. DETAILED DESCRIPTION

[0039] Refer to the following Figure 1 To describe a digital inspection and management system for the ship assembly construction process of the present invention. In the description of this embodiment, it should be understood that the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features, that is, include one or more of the features. In the description of the present invention, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. When a feature "includes or contains" one or some of the features it covers, unless otherwise specifically described, this indicates that other features are not excluded and may further include other features.

[0040] Unless otherwise clearly defined and limited, the terms "set", "install", "connect", "connect", "fix", "couple" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. A person skilled in the art should be able to understand the specific meanings of the above terms in the present invention according to the specific circumstances.

[0041] In addition, in the description of this embodiment, the first feature being "above" or "below" the second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact through another feature between them. That is, in the description of this embodiment, the first feature being "above", "above", and "above" the second feature includes the first feature being directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. The first feature being "below", "below", or "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0042] In the description of the present embodiment, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0043] like Figure 1As shown, an embodiment of the present invention provides a digital inspection management system for ship assembly construction process, and the management system includes a template generation unit, an editing unit and a display unit. The template generation unit is used to generate a management template according to the relevant information of the product structure, production process and process requirements in the ship construction process. The management template includes each construction stage in the ship assembly construction process, the inspection object of each construction stage, the inspection item of each inspection object, the inspection level of each inspection item, the inspection element of each inspection item, the inspection requirement of each inspection element and the detection method of each inspection requirement. The editing unit is used for each department to modify the management template according to the actual situation and fill in the content in the management template. Since the stage division method or name of different shipyards may be different, it is necessary to modify the management template according to the actual situation of different shipyards. At the same time, when filling in the report, the subsequent inspection content is filled in according to the inspection content filled in the previous period. That is, first determine the various construction stages of the ship assembly construction process, then determine the inspection object according to the construction stage, then determine the inspection item according to the inspection object, then determine the inspection level and inspection element according to the inspection item, and finally determine the inspection requirement according to the inspection element and determine the inspection method according to the inspection requirement. The display unit is used to display the management template, so that data information can be shared among departments, and the filling of the management template is convenient. At the same time, by setting the display unit, the information is simple and clear, so that the communication of on-site delivery and inspection is smoother, the workload of on-site inspection of the shipowner is reduced, the efficiency and quality of inspection work are effectively improved, and high-quality delivery of ships is achieved. Optionally, the management template can be a table.

[0044] Furthermore, the management system also includes a login unit and a permission management unit. The login unit is used for the relevant departments in the shipbuilding process to log in to the management system. The permission management unit is used to limit the content that each relevant department can modify or fill in through the editing unit. Each relevant department can only fill in the inspection items that it is responsible for, so as to track and trace the source and clarify the division of responsibilities of each relevant department.

[0045] Furthermore, the construction stage includes the production technology preparation stage, the advance engineering stage and the post-engineering stage. Among them, the production technology preparation stage refers to the process of preparing for subsequent production. The advance engineering stage refers to the construction process from the start of ship product construction to the start of slipway / dock loading. The post-engineering stage refers to the construction process from the start of slipway / dock loading to the ship trial delivery. The production technology preparation stage includes the signing of contracts and technical specifications, the signing of equipment technology agreements, the procurement of raw materials / equipment, detailed design and production design. The advance engineering stage includes steel pretreatment, cutting, processing, block assembly, block pre-outfitting, block painting, general assembly and general assembly outfitting. The post-engineering stage includes loading, dock outfitting, launching, mooring test, sea trial and delivery. The block assembly stage includes small assembly, medium assembly and large assembly stages. The stage division method or name of different shipyards may be different, but the overall idea is the same. That is, the division of construction stages is based on the structural characteristics of the ship and the manufacturing process, breaking down the complete ship assembly construction into a series of continuous production stages completed in different departments and at different times.

[0046] Furthermore, the inspection objects in the production technology preparation stage are purchased parts such as steel, welding materials, pipes and equipment. The inspection objects in the pre-engineering stage are pre-processed steel, parts after cutting and processing, small, medium and large assemblies after welding and other structural parts. The inspection objects in the post-engineering stage are processed pipe sections, welded bases and other outfitting parts.

[0047] Furthermore, due to the differences in the final assembly and construction processes of different shipyards and different ship types, the inspection process requirements will also be different. Therefore, the inspection items of the built ship are determined according to the actual situation. For a certain ship, in the production technology preparation stage, the inspection items of steel include physical and chemical tests, non-destructive testing, and appearance testing. In the pretreatment stage of the advanced engineering stage, the inspection item of steel is pretreatment inspection. In the group establishment stage of the advanced engineering stage, the inspection items of the rib structure include pre-welding inspection and post-welding inspection.

[0048] Furthermore, for each inspection item, the corresponding inspection level is determined according to the importance of the inspection item. The inspection levels include self / mutual inspection, special inspection and shipowner inspection. Among them, the self / mutual inspection level refers to the self-inspection and mutual inspection of the inspection items by the shipyard production department. The special inspection level means that after the shipyard production department completes the self-inspection and mutual inspection, the shipyard quality management department needs to conduct a special inspection on the inspection items. Shipowner inspection means that after the shipyard production department and the quality management department complete the self-inspection, mutual inspection and special inspection, the shipowner needs to inspect and review the inspection items again. From the above, it can be seen that self-inspection and mutual inspection are inspections that must be carried out, and special inspections, shipowner inspections, etc. are inspections that are increased according to the importance of the inspection items. By setting different inspection levels for inspection items, hierarchical control of inspection work is achieved, which can improve inspection efficiency and quality.

[0049] Furthermore, for each inspection item, the inspection elements corresponding to the inspection item are sorted out, that is, the specific inspection content that needs to be completed in the inspection item is determined. Since different shipyards and different ship types have different assembly and construction processes, the inspection process requirements will also be different. Therefore, the inspection items and inspection elements of the built ship are determined according to the actual situation. For physical and chemical tests on steel, the inspection elements are all or part of the three items of chemical analysis, mechanical analysis and metallographic analysis. For steel pretreatment inspection, the inspection elements include the thickness of the steel plate paint film and the surface roughness of the steel plate.

[0050] Furthermore, according to the ship inspection process documents, standards or specifications compiled by the design department, for each inspection element, the inspection requirements that the inspection element needs to meet are sorted out. The inspection requirements include accuracy requirements, record requirements, inspection forms and requirements sources.

[0051] Among them, the precision requirement is the quality index that the inspection element needs to meet, including quantitative requirements and qualitative requirements. The quantitative requirement is to judge whether the inspection element is qualified by quantitative indicators. The qualitative requirement is to judge whether the inspection element is qualified by text description. The record requirement is the relevant information that needs to be stored to complete the inspection element. Self / mutual inspection, special inspection, shipowner inspection, etc. judge whether the inspection element is qualified according to the precision requirements. If qualified, it will be transferred to the subsequent production inspection link. If unqualified, it will be transferred to the corresponding unqualified product processing process. Regarding the quantitative requirements, taking the physical and chemical test of steel as an example, the inspection process requirements of the chemical analysis inspection element include the detection of the chemical element composition required by the process (such as C, N, Si), and the content of each chemical element must be within the specified range. In addition, taking the paint film thickness inspection element of steel as an example, its inspection process requirement is that the thickness of the paint film is between the set values. For qualitative requirements, taking the surface quality inspection element of welding materials as an example, its inspection process requirement is that the surface of the welding material is clean, oil-free, and damage-free.

[0052] Record requirements are the relevant information that needs to be stored to complete the inspection elements, including inspection records, reports, videos and photos. For the inspection elements of some production links, it is sufficient to store the inspection record book, but for some important production links, it is also required to use photos or videos to record the production inspection process for subsequent quality traceability.

[0053] The inspection form is the name or album number of the inspection record book / report corresponding to the inspection element.

[0054] The source of the requirement is the name or atlas number of the inspection process document, standard or specification on which the inspection element accuracy requirement is based.

[0055] Furthermore, for each inspection requirement of the inspection element, the available inspection methods are sorted out. The inspection methods include the currently used inspection method, the digital inspection method and the inspection method used by this ship. The currently used inspection method is the inspection method currently used by the shipyard. The digital inspection method is the inspection method using digital instruments. The inspection method used by this ship is the inspection method used by this ship in the end, which needs to be comprehensively considered from the aspects of cost, efficiency, and on-site environment. It can be the currently used inspection method, the digital inspection method or other methods. Taking the pipe section processing in the subsequent engineering stage as an example, the current inspection method is to manually detect whether the length and bending angle of the pipe section are qualified by tools such as calipers and steel templates. The digital inspection method includes using equipment such as laser scanners to collect point cloud data of the processed pipe section, using the point cloud data to build a three-dimensional model of the pipe section, and comparing it with the theoretical three-dimensional model to detect whether it is qualified. Use high-precision cameras and combine AI algorithms to inspect the processed pipe section. The pipe section inspection method used by this ship needs to be determined by the relevant departments after fully considering various factors.

[0056] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
