Description

Technical Field

[0001] The present application relates to the fields of welding technology and data management technology, and in particular to a data model system and a method for using the system for vertical welding operations of a ship group. Background Art

[0002] In the shipbuilding system, the subassembly is the most fundamental structural unit. A large ship is often composed of tens of thousands of subassembly components assembled through precise splicing and welding processes. Subassembly production is the foundation of shipbuilding. Subassembly production covers multiple key links, including process design, production planning and scheduling, assembly and welding, logistics and transportation, and quality inspection. As data flows between these links, differences in data management standards and statistical calibers require tedious data conversion and reorganization. This not only consumes a significant amount of manpower and time, but also easily leads to errors and information loss during the data conversion process, which directly hinders the flow of data between links and prevents efficient and smooth data transmission and sharing.

[0003] In the prior art, the application number is CN202411063224.7, which provides a digital twin system, including an information source collection module, a basic large model module, a scene large model module and a digital twin model module. The information source collection module can obtain the first key data and the second key data, the basic large model module generates the first target data according to the first key data, the scene large model module generates the second target data according to the second key data, and the digital twin model module updates the digital twin model according to the first target data and the second target data, realizing the transformation from manual acquisition and processing of data to automatic acquisition and processing of data, improving the credibility, richness, timeliness and accuracy of the data, and thus improving the accuracy of the digital twin model and the timeliness and synchronization of updates. The above-mentioned data modeling method in the field of ships is to facilitate the construction of a data twin system, and is a relatively generalized modeling method.

[0004] Application number CN20241124166.4 discloses a method and system for calculating the labor quota for the pretreatment process of a ship structure component. The method comprises: obtaining a sample structural component, extracting corresponding process information based on the pretreatment process of the sample structural component, determining a target factory area for the pretreatment process of the sample structural component, and querying a pre-built universal quota labor time database to determine the benchmark labor time corresponding to the target factory area, a number of area size intervals, and a correction coefficient corresponding to each of the area size intervals. Based on the area size intervals and the area of ​​each steel plate in the sample structural component, a corresponding correction coefficient is marked on each steel plate. Based on the benchmark labor time and the steel plate area, a labor quota is calculated for each steel plate in the sample structural component, and the labor quota is corrected using the correction coefficient. The labor time of the sample structural component after the quota correction is obtained, thereby improving the efficiency and accuracy of the labor quota calculation. This method only models the labor time data of ship structures and does not provide comprehensive, full-cycle modeling.

[0005] The data generated in shipbuilding workshops is diverse and complex, with complex relationships. Existing data models lack systematicity and organization, and the logical relationships between data are unclear. These issues greatly complicate shipbuilding planning and make it difficult to accurately implement data-based scheduling and control. This, to a certain extent, hinders the digitalization and intelligentization of shipbuilding management. Summary of the Invention

[0055] Specifically, in this application,

[0056] Reference Figures 1 to 4 As shown, a data model system for vertical welding operations of a ship group according to an embodiment of the present application includes:

[0057] The welding resource data module is used to count and describe the site resources, worker resources, material resources and equipment resources involved in the welding process, and set attributes and constraints.

[0058] The assembly and welding process data module is used to describe the process information of the assembly and welding workshop. The process information includes: process specifications and process flow.

[0059] The group vertical welding work order planning module is used to formulate the group vertical welding production plan based on the welding resource data module and the welding process data module.

[0060] The welding monitoring data module is used to monitor and record the actual execution data of the group's welding production plan in real time.

[0061] This application models the data involved in the group vertical welding operation from four aspects: resources, process, plan, and execution, thereby achieving refined management of the entire welding process, improving resource utilization efficiency, ensuring the strict implementation of process specifications, optimizing the formulation and execution of production plans, and enhancing the transparency and traceability of the operation process. It provides strong support for improving the efficiency and quality of shipbuilding, and solves the problems of differences and lack of systematicity in group vertical welding data management standards and statistical calibers, as well as unclear logical relationships between data.

[0062] During the work process, the assembly and welding resource data module is first used to count and describe the required site, workers, materials, and equipment resources, while also setting the corresponding attributes and constraints. Next, the assembly and welding process data module is used to describe in detail the process specifications and procedures for the assembly and welding workshop. Based on the data captured by the assembly and welding resource data module and the assembly and welding process data module, a reasonable assembly and welding production plan is developed using the assembly and welding work order planning model. Finally, operations are executed according to the production plan, and the assembly and welding monitoring data model is used to monitor and record the execution of the production plan in real time to ensure smooth and consistent operation.

[0063] In some possible embodiments, the welding resource data module, wherein: the attributes of the site resources include the number of sites, the type of site, the site number, and the site area; the constraint condition of the site resources is that the site area is greater than or equal to the required area.

[0064] Specifically, the attributes of the site resources include the number of sites, site type, site number, and site area, and the constraint is that the site area is greater than or equal to the required area.

[0065] Site resources describe the site information for assembly operations. Each site has a unique number, and site types include rib welding areas, small component welding areas, and more. Using site area and number helps to more accurately plan and allocate site resources, ensuring that each assembly has sufficient space for placement.

[0066] The attributes of worker resources include the number of workers, available working hours, job number, job type, skill proficiency, and team number; the constraint condition of worker resources is that the number of workers is equal to the required number.

[0067] Specifically, the attribute values ​​of worker resources include the number of workers, available working hours, work number, job type, skill proficiency, and team number, and the constraint is that the number of workers is equal to the required number.

[0068] The worker ID in the worker resource represents a unique identifier for the worker, facilitating personnel management, accurately assigning tasks to each employee, and ensuring traceability during assembly and welding operations. The upper-level management unit for workers in the assembly and welding workshop is the work team, which comprises workers of different trades. Workers are assigned a team ID. Data on a worker's trade type and available working hours are key information for scheduling. Skill proficiency data describes a worker's skill level. During engineering operations, the required number of workers for each trade must be met.

[0069] The attributes of material resources include part 3D model, part shape, part quantity, part material, part number, and part weight; the constraint condition of material resources is that the number of parts is equal to the required quantity.

[0070] Specifically, the attributes of material resources include part 3D model, part shape, part quantity, part material, part number, and part weight, and the constraint is that the part quantity is equal to the required quantity.

[0071] The Material Resource Data module describes the material information for the subassembly components. Each rib and rib plate component is uniquely numbered, facilitating quality control and monitoring. Part information also includes the part's 3D model, shape, weight, and material. Part shape can be further used to calculate the area it occupies when placed flat, which is used for welding site allocation. During welding, the number of parts must be equal to the required quantity.

[0072] The attributes of equipment resources include usage records, maintenance records, equipment name, equipment quantity, equipment purpose, and equipment number; the constraints of equipment resources are that the number of equipment is equal to the required number and that startup and shutdown actions can be performed.

[0073] Specifically, the attributes of the device resources include usage records, maintenance records, device name, device quantity, device purpose, and device number. The constraints are that the device quantity is equal to the required quantity and that both startup and shutdown actions can be performed.

[0074] The Equipment Resource Data module provides data on welding equipment. Managing equipment name, number, purpose, and quantity helps accurately understand the workshop's equipment inventory and optimize equipment resource allocation. Usage records can be used to analyze equipment usage, optimize workflows, and improve overall production efficiency. Maintenance records ensure equipment reliability, facilitate effective maintenance plans, reduce failure rates, and extend service life.

[0075] Among them, the site resource is determined by the attributes of the material resource; the attribute of the welding resource data module is the project number, which is described by the string string.

[0076] In some possible embodiments, the group assembly welding work order planning module, wherein the attributes of the process specification and the process flow are the assembly number, which is described by a string data type.

[0077] The process specification is used to define the welding requirements for workers, welding parameters, welding sites, welding materials, equipment, and parts; the process flow is used to define the steps from welding parts to finished products.

[0078] Specifically, if Figure 2 As shown, the welding process data module consists of process specifications and process sequences. Its attribute is the assembly number, described by a string. An example of a process specification is the welding process specification, which consists of workers, welding parameters, welding site, welding materials, equipment, and parts. The process flow describes the series of steps from ribs, vertical and horizontal sections to finished products. The process specification includes requirements for workers, parts, equipment, welding site, welding materials, and welding parameters. The welding process specification specifies environmental information for the welding site. The construction site must be kept clean and dry to prevent excessive dust, iron filings, and moisture from entering various welding equipment, which could affect its service life. The welding process specification also specifies welding parameters, including current type and polarity, welding current, arc voltage, welding speed, and heat input. These parameters are primarily described using real numbers. Welding process specifications can be further specified, such as CO2 gas shielded welding process specifications, submerged arc welding process specifications, and vertical gas arc welding process specifications.

[0079] In terms of worker information, operations can only begin when the number, type of work, and skill proficiency of workers are met; in terms of parts information, first, the number of parts must meet the start-up requirements, and secondly, the placement of parts needs to occupy the site location, and the parts cannot overlap. Welding can only be carried out when the site space is met; in terms of equipment information, the number of equipment needs to meet the number of equipment required by the process specifications; in terms of welding materials, the type, diameter, and shielding gas of the welding materials used are different for different welding methods and part materials; in terms of the welding site, work needs to begin in a weather environment suitable for the start of work and with sufficient site area.

[0080] In some specific embodiments, the welding monitoring data module is connected to the group vertical welding work order planning module, and the digital domain data in the group vertical welding work order planning module is compared with the physical domain data in the welding monitoring data module to reflect the deviation between execution and plan.

[0081] Specifically, the digital domain data in the group vertical assembly welding work order planning module includes: group vertical assembly welding work order plan, which is used to generate the planned start and end time of the work order; site layout plan, which is used to plan the site area and working period of assembly processing; worker allocation plan, which is used to refine the process tasks and assign them to specific workers; process operation plan, which is used to formulate the start and end time of the process, the number of workers required, the site area and processing equipment; equipment usage plan, which is used to plan the equipment usage period and operators; parts logistics plan, which is used to plan the transportation of parts, the delivery of pallets to the workstations and the time.

[0082] like Figure 3 As shown, specifically, the group vertical welding work order planning module consists of site layout plan, worker allocation plan, process operation plan, equipment use plan, and parts logistics plan, and its attributes are work order number, work order plan start time, and work order plan end time.

[0083] The process operation plan further refines the work order plan, giving the start and end time of the process, the number of workers, the site area and the processing equipment; the site layout plan gives the site area and operation time period for assembly processing, and maps the assembly number and site area; the worker allocation plan is based on the process operation plan and refines the process tasks to individual workers; the equipment use plan gives the time period for equipment use and the equipment operators; the parts logistics plan describes the number and quantity of the transported parts, the delivery and arrival stations of the pallets, and the delivery time.

[0084] In some possible embodiments, the site layout plan, the worker allocation plan, the process operation plan, the equipment usage plan, and the parts logistics plan are generated based on the time of the team's vertical welding work order plan.

[0085] Specifically, the group vertical welding work order planning module clearly defines the planned start and end time of the work order, and the remaining plans are arranged based on the planned time of the group vertical welding work order.

[0086] In some possible embodiments, the physical domain data in the assembly and welding monitoring data module include: group assembly and welding work order monitoring, which is associated with the group assembly and welding work order plan and is used to monitor the actual start and end time of the work order; site layout monitoring, which is associated with the site layout plan and is used to monitor the actual layout and time period of the assembly; worker allocation monitoring, which is associated with the worker allocation plan and is used to record the process number of the assigned worker's work; process operation monitoring, which is associated with the process operation plan and is used to record the actual operation time period and the number of operators of the process; equipment monitoring, which is associated with the equipment usage plan and is used to record the equipment usage time period and the actual operator; parts logistics monitoring, which is associated with the parts logistics plan and is used to record the part number in the actual pallet and the actual delivery time.

[0087] like Figure 4 As shown, the welding monitoring data module consists of several components: team-based welding work order monitoring, site layout monitoring, worker allocation monitoring, process operation monitoring, welding environment data, equipment monitoring, and parts logistics monitoring. This data model focuses on the physical domain. The comparison between the physical and digital domains reflects deviations from the plan and serves as the data foundation for the system's feedback scheduling.

[0088] The group assembly welding work order monitoring gives the actual start and end time of the work order; the parts logistics monitoring describes the part number in the actual pallet and the actual delivery time; the process operation monitoring gives the actual operation time period and the number of operators; the equipment monitoring records the equipment usage time period and the actual operator; the site layout monitoring gives the actual layout and time period of the assembly; the worker allocation monitoring gives the process number that the worker needs to perform.

[0089] In some possible embodiments, the physical domain data in the welding monitoring data module further includes welding environment data, which is used to record environmental information of the welding site, including noise, temperature, humidity and weather.

[0090] A second aspect of the present application provides a method for using a data model system for a ship group vertical welding operation, comprising:

[0091] Obtain information on assembly and welding operations, and according to the assembly and welding resource data module, count the equipment resources, site resources, worker resources, and material resources of the assembly and welding workshop, and use the data types specified in the module to describe the attributes of each resource.

[0092] According to the assembly and welding process data module, the process specifications and process flows involved in assembly and welding are counted.

[0093] According to the statistical data information of the welding resource data module and the welding process data module, a group vertical welding production plan is formulated, and the group vertical welding production plan is statistically recorded through the welding plan data module.

[0094] Execute according to the group's vertical welding production plan, record the actual execution data through the welding execution monitoring data module, compare the actual execution data with the production plan data to obtain relevant deviations, and adjust the production plan in real time according to the deviations.

[0095] Specifically, workers can view the process information, relevant drawings, job start time, and duration requirements for their assigned welding process on their terminals. Using the welding resource data module, they can calculate the equipment, site, worker, and material resources in the welding workshop, describing them using the data types specified in the module. This allows them to determine the number of resources available in the workshop.

[0096] Secondly, the welding process data module collects data on the process types and process sequences involved in assembly welding, and describes them using the data types specified in the model. This allows the workshop to obtain the process information it possesses.

[0097] Reference Figure 2 As shown, the specified data type is the string type represented by each attribute. For example, the welding process data module includes welding parameters, which include attributes such as welding current, heat input, current type and polarity. The data types specified for welding current and heat input are Real string data types, and the data types specified for current type and polarity are String string data types.

[0098] Then, based on the statistical information from the welding resource data module and the welding process data module, the team will be assigned a welding production plan. Once the specific plan is obtained, the detailed information of the plan will be statistically recorded in the welding plan data module, describing it using the data type specified in the module. This will allow the workshop to obtain the planned data.

[0099] Finally, work begins according to the welding plan. The welding execution monitoring data module records the actual execution data of the plan and compares it with the planned data to obtain relevant deviations. The deviations can be used to adjust the plan in real time.

[0100] In the above embodiment, the specified data type is: the data type specified in the module is Figures 1-4 The data components of each module. For example, device resources include usage records, maintenance records, device name, device purpose, and device number. The corresponding data type is string.

[0101] It should be noted that in the attached Figure 1 To the attached Figure 4 In the block definition diagram, "block" refers to a block; "integer" refers to an integer; "string" refers to a string; "real" refers to a real number; "complex" refers to complex data, such as files; "parts" refers to components; "constraints" refers to constraints; "boolean" refers to Boolean values; and "values" refers to the various value attributes of the block. Different data types are used to specify how values ​​are recorded.

[0102] In some possible embodiments, the process specifications are the welding requirements for workers, welding parameters, welding sites, welding materials, equipment and parts that meet the needs of group vertical welding operations; the process flow is the steps from parts to finished products in group vertical welding operations.

[0103] Among them, the welding and installation requirements must be met. In terms of worker information, the operation can only be started when the number, type of work, and skill proficiency of the workers are met; in terms of parts information, first of all, the number of parts needs to meet the start-up requirements, and secondly, the placement of parts needs to occupy the site location, and the parts cannot be overlapped. Welding and installation must be carried out under the condition that the site space is met; in terms of equipment information, the number of equipment needs to meet the number of equipment required by the process specifications; in terms of welding materials, for different welding methods and parts materials, the type, diameter and shielding gas of the welding materials used are also different; in terms of the welding site, work needs to be started under a weather environment suitable for the start of work and sufficient site area.

[0104] This application addresses the discrepancies between group vertical welding data management standards and statistical calibers, sorts out the data components involved in group vertical welding, and specifies the data types used to describe the corresponding data. At the same time, to address the lack of systematicity in group vertical welding data and the unclear logical relationships between data, the SysML modeling language is used to model the data involved in group vertical welding operations from four aspects: resources, processes, planning, and execution, so that the data relationships between them are clear.

[0105] The above describes the specific embodiments of the present application. It should be understood that the present application is not limited to the specific embodiments described above, and those skilled in the art may make various modifications or variations within the scope of the claims, which do not affect the substantive content of the present application. The above preferred features may be used in any combination as long as they do not conflict with each other.
