Description

Technical Field

[0001] This invention relates to the field of iron and steel metallurgy technology, and more specifically, to a collaborative design method, system, equipment, and storage medium for a hot continuous rolling production line. Background Technology

[0002] Hot strip rolling production lines are a crucial production link in the steel industry, widely used in high-end manufacturing sectors such as automobiles, shipbuilding, rail transportation, and energy pipelines. As downstream industries increasingly demand higher product precision, performance consistency, and faster delivery times, the design quality and construction efficiency of hot strip rolling production lines have become critical factors influencing overall competitiveness. In recent years, the steel industry has accelerated its transformation towards intelligent and digital technologies, with new technologies such as digital twins, parametric modeling, and collaborative design platforms gradually being introduced into the production line design and optimization process.

[0003] In related technologies, the current design of hot strip rolling production lines still generally adopts a decentralized and regionalized traditional model. Under this model, each equipment area is independently managed by different designers or teams. Key parameters between equipment, such as interface dimensions, roller table elevation, and roll gap position, rely on manual verification and drawing transfer for coordination. This results in problems such as insufficient collaboration and data fragmentation, which restricts the accuracy and construction efficiency of the production line. Summary of the Invention

[0004] The problem addressed by this invention is how to improve the design accuracy and efficiency of hot strip rolling production lines.

[0005] To address the above problems, this invention provides a collaborative design method, system, equipment, and storage medium for hot continuous rolling production lines.

[0006] In a first aspect, the collaborative design method for a hot continuous rolling mill production line of the present invention includes: A top-level layout framework is established based on process specifications and digital twin technology. The top-level layout framework includes equipment planar relationships, interface constraints, layout coordinate references, and equipment list. Based on the equipment list and the interface constraints, the design tasks are distributed to each design node through the PLM system, and the permissions of the design nodes and their adjacent design nodes are configured. After the permission configuration of the design nodes and their adjacent design nodes is completed, an interface data sharing pool is constructed. Each design node determines the spatial position reference of the corresponding equipment in the production line based on the equipment planar relationship; Based on the interface data in the interface data sharing pool and the interface constraints, a device-level layout of the device corresponding to the design node is generated, wherein the interfaces in the device-level layout are matched with the interface constraints; Parametric modeling technology is used to establish a dynamic relationship between the component dimensions in the equipment-level layout and the layout coordinate reference. The layout coordinate reference is used as the global origin of the entire assembly line, and the assembly positioning of each device is completed according to the spatial position reference of each device.

[0007] Optionally, establishing a top-level layout framework based on process specifications and digital twin technology includes: The associated dimensions between each of the devices and the positioning dimensions of each device relative to the production reference are determined according to the process specifications. Based on digital twin technology, a planar layout is drawn for the shape of each device and the center lines in three directions to build an initial skeleton of the device. The initial skeleton of the device includes the spatial position reference points and / or reference lines of each device. Using the associated dimensions and the positioning dimensions as constraints, adjust the position reference of each device in the initial skeleton of the equipment until the relative position between each device satisfies the associated dimensions and the position of each device relative to the production reference satisfies the positioning dimensions. The adjusted skeleton, which includes the position reference of each of the devices, is used as the top-level layout skeleton.

[0008] Optionally, based on the device list and the interface constraints, the design task is distributed to each design node through the PLM system, and permissions are configured for the design nodes and adjacent design nodes. After the permission configuration of the design nodes and adjacent design nodes is completed, an interface data sharing pool is constructed, including: According to the equipment list, the design task for each of the equipment is distributed to the corresponding design node in the PLM system; Based on the interface constraints, determine the interface correspondence between adjacent devices; Based on the interface correspondence, each design node is configured with read and write permissions for its corresponding device, and adjacent design nodes are configured with read permissions for the interface data of that device. After the permissions of the design node and the adjacent design nodes are configured, the interface data generated by each device is aggregated into the shared pool to obtain the interface data shared pool.

[0009] Optionally, each design node determines the spatial location reference of the equipment corresponding to that design node in the production line based on the equipment planar relationship, including: Extract the planar positioning reference of the equipment corresponding to the design node from the top-level layout skeleton. The planar positioning reference includes the intersection of the equipment centerline and / or the intersection of the roller centerline. The coordinate values ​​of the planar positioning reference under the layout coordinate reference are used as the spatial position reference of the equipment corresponding to the design node.

[0010] Optionally, generating the device-level layout of the device corresponding to the design node based on the interface data in the interface data sharing pool and the interface constraints includes: Using the spatial location reference as the positioning origin of the device, a device-level skeleton is established, which includes the centerline and outer contour of the device. The initial position and initial size of each interface on the device are determined based on the interface constraints. Based on the interface data of adjacent devices in the interface data sharing pool, the initial position is adjusted to obtain the interface position of the device that matches the interface of the adjacent devices; Associating the interface location and the initial size with the device-level skeleton generates the device-level layout for the device.

[0011] Optionally, the step of employing parametric modeling technology to dynamically link the component dimensions in the device-level layout with the layout coordinate reference includes: By using the parametric modeling technique, a correlation formula is established between the vertical dimensions of components in the device-level layout and the layout coordinate reference, so that the vertical dimensions are automatically adjusted as the layout coordinate reference changes. Based on the aforementioned correlation formula, a parametric constraint relationship is established between the spatial position reference of each device and the layout coordinate reference, so that the position of the device moves automatically as the layout coordinate reference changes.

[0012] Optionally, the step of using the layout coordinate reference as the global origin of the entire assembly line and completing the assembly positioning of each device according to the spatial position reference of each device includes: Align the positioning reference points in the device-level skeleton of each device with the corresponding spatial position references; Using the layout coordinate reference as the origin of the global coordinate system, the coordinates of the positioning reference point of each device are converted into coordinate values ​​in the global coordinate system; Based on the converted coordinate values, the device-level skeleton of each device is placed at the corresponding position in the global coordinate system, thus completing the assembly and positioning of each device.

[0013] Secondly, the present invention provides a collaborative design system for a hot continuous rolling production line, comprising: The skeleton building unit is used to build a top-level layout skeleton according to process specifications and digital twin technology. The top-level layout skeleton includes equipment planar relationships, interface constraints, layout coordinate references, and equipment list. The distribution configuration unit is used to distribute design tasks to each design node through the PLM system according to the device list and the interface constraints, and to configure permissions for the design nodes and adjacent design nodes. After the permission configuration of the design nodes and adjacent design nodes is completed, an interface data sharing pool is constructed. A positioning unit is used to determine the spatial position reference of the equipment corresponding to each design node in the production line based on the equipment planar relationship; A generation unit is used to generate a device-level layout of the device corresponding to the design node based on the interface data in the interface data sharing pool and the interface constraints, wherein the interfaces in the device-level layout are matched with the interface constraints; The assembly positioning unit is used to establish a dynamic relationship between the component dimensions in the equipment-level layout and the layout coordinate reference using parametric modeling technology, and to complete the assembly positioning of each device based on the spatial position reference of each device, using the layout coordinate reference as the global origin of the entire assembly line.

[0014] Thirdly, an electronic device according to the present invention includes: a processor and a memory, the memory being used to store a computer program; When the computer program is loaded by the processor, it causes the processor to execute the above-described collaborative design method for hot strip mill production lines.

[0015] Fourthly, the present invention provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the above-described collaborative design method for hot strip mill production lines.

[0016] The collaborative design method, system, equipment, and storage medium for hot strip mill production lines of this invention uniformly define the planar relationships, interface constraints, and layout coordinate references of equipment through a top-level layout skeleton. All equipment generates equipment-level layouts within this framework, and the interfaces in the equipment-level layouts are required to match the top-level interface constraints. This fundamentally avoids dimensional conflicts that are difficult to eliminate even with manual verification in traditional designs, such as misalignment of adjacent mill roll gaps and mismatched roller table elevations. Furthermore, using the top-level layout skeleton as the sole data source, each design node determines the spatial location reference of the equipment based on it, and dynamically associates the equipment-level layout with the planar relationships and coordinate references in the skeleton. This ensures that equipment modeling remains consistent with the overall production line layout. Tasks are distributed through a PLM system, and permissions are configured for design nodes and their adjacent nodes. After the design is completed, interface data is automatically imported into a shared pool. Adjacent nodes only have read permissions and no modification permissions, ensuring data security while allowing equipment managers to obtain interface information of adjacent equipment in real time. When a change occurs to a piece of equipment and affects adjacent equipment, interference checks and associated designs in the 3D software can be automatically triggered and pushed, eliminating the need for repeated transfer of drawings and manual verification in traditional methods, significantly shortening the design cycle and reducing change costs. Meanwhile, parametric modeling technology is used to establish a correlation formula between component dimensions and layout coordinate references, and the equipment spatial position references are bound to the layout coordinate references. This ensures that once the layout references are adjusted, the dimensions and positions of all equipment are automatically updated synchronously, ensuring that the entire line design always meets the process specifications and avoiding inconsistencies caused by design iterations.

[0017] In summary, this invention significantly improves the design accuracy and efficiency of hot strip rolling production lines by unifying design benchmarks through top-level constraints, achieving hierarchical collaboration to enable interoperability and data sharing, driving dynamic synchronization of dimensions and positions through parameter association, and conducting closed-loop verification throughout the entire process. It overcomes the inherent defects of traditional decentralized design, such as insufficient collaboration, data fragmentation, and repeated changes. Attached Figure Description

[0025] Combination Figure 1 As shown, this embodiment of the invention provides a collaborative design method for a hot rolling mill production line, including: A top-level layout framework is established based on process specifications and digital twin technology. The top-level layout framework includes equipment planar relationships, interface constraints, layout coordinate references, and equipment list.

[0026] Specifically, designers can obtain the process specifications of the hot strip rolling production line to determine the inter-equipment dimensions (such as the center distance between adjacent mills) and the positioning dimensions of each piece of equipment relative to production references (such as the rolling centerline and elevation reference). Using digital twin technology, the outline of each piece of equipment and its centerlines in three directions are drawn in a 3D design environment to form an initial skeleton. Each region (such as the roughing and finishing rolling areas) is then decomposed into points or lines and represented on the skeleton. Using the aforementioned inter-equipment and positioning dimensions as constraints, the positional references of each piece of equipment are adjusted until both the relative and absolute positions meet the requirements. Finally, a top-level layout skeleton is obtained, including the equipment planar relationships, interface constraints, layout coordinate references, and an equipment list. Assembly relationships are then established between each piece of equipment and the skeleton.

[0027] Based on the equipment list and the interface constraints, the design tasks are distributed to each design node through the PLM system, and permissions are configured for the design nodes and their adjacent design nodes. Once the permissions of the design nodes and their adjacent design nodes are configured, an interface data sharing pool is constructed.

[0028] Specifically, based on the equipment list and interface constraints, tasks are distributed, permissions are configured, and an interface data sharing pool is built through the PLM system. The lead designer can create the equipment list in the PLM system (e.g., Teamcenter). After review, the design tasks for each piece of equipment are distributed to the corresponding design nodes. During permission configuration, each design node has read and write permissions for the equipment it is responsible for, while adjacent design nodes only have read permissions for the interface data of that equipment. After permission configuration, the interface data generated during the design process of each piece of equipment, such as hydraulic cylinder interfaces, cooling water interfaces, and dry oil points, are aggregated into the sharing pool for direct use by subsequent piping and other professional designs, eliminating the need for manual collection of drawings.

[0029] Each design node determines the spatial location reference of the corresponding equipment in the production line based on the equipment planar relationship.

[0030] Specifically, the design node extracts the planar positioning reference of the equipment from the top-level layout skeleton, such as the intersection of the equipment centerline or the intersection of the roller centerline, and uses the coordinate value of the intersection under the layout coordinate reference as the spatial position reference of the equipment.

[0031] Based on the interface data in the interface data sharing pool and the interface constraints, a device-level layout for the device corresponding to the design node is generated, wherein the interfaces in the device-level layout are matched with the interface constraints.

[0032] Specifically, based on the interface data and constraints in the interface data sharing pool, the device-level layout of the device is generated. The design nodes establish a device-level skeleton containing the device's centerline and outline, using the spatial location reference as the origin. The initial positions and dimensions of each interface are determined according to the interface constraints. Interface data from adjacent devices is read from the sharing pool, and the initial positions are adjusted to match the interfaces of adjacent devices (interface dimensions typically remain unchanged from their initial values). Finally, the adjusted interface positions and initial dimensions are associated with the device-level skeleton to form the device-level layout.

[0033] In a preferred embodiment of the present invention, combined with Figure 2 As shown in the schematic diagram of the equipment-level constraint skeleton in this embodiment, the horizontal straight line is the rolling center line, and the bottom horizontal straight line is the elevation reference line; the left side is labeled " Φ The 360° circular component is the side guide roller, with its center horizontally distanced from the center of the main roller assembly by 800°, and its local structural thickness marked as 4°; the vertically arranged pairs of… Φ The 600” circular component represents the rolling mill's work rolls and support rolls. The vertical dimension of the roll system's center to the rolling line is “360”, and the overall center distance of the equipment group is “3200”, divided into two segments of “1210” and “850”. Horizontally, “475” indicates the horizontal distance between the upper water collection pipe and the roll system's center line, and “360” indicates the horizontal distance between the lower water collection pipe and the rolling line's center. Vertically, “277” indicates the height of the upper water collection pipe's center from the rolling center line, “270” indicates the height of the water collection trough's center from the rolling center line, and “866” indicates the height of the lower water collection pipe's center from the elevation baseline. The “upper water collection pipe,” “lower water collection pipe,” and “water collection trough” are components of the cooling system. The diameter of the lower water collection pipe is marked as… Φ 360”; the “150” on the right is the safety clearance between the edge of the roll system and the rolling line. For example... Figure 2 As shown, the implementation process of device-level layout refinement in this embodiment is illustrated by example, including baseline inheritance and global alignment. Figure 2 The rolling mill centerline (horizontal baseline) serves as the core reference, and the position and dimensions of all equipment and pipelines are referenced to this baseline to ensure alignment with the overall constraints of the entire line. This is achieved by simplifying the representation of the rolling mill roll system (arranged vertically). Φ 600mm roller), cooling manifold (upper / lower water collection pipe), Φ The outline and centerline of the water collection tank (360mm) visually represent the overall spatial footprint of the equipment and the relative positions of its core components. In this embodiment, all dimensional constraints are controlled by the top-level layout, leaving no room for independent changes. Roller system constraints: The center distance of the roller group is marked as 3200mm, and the segment dimensions are 1210mm and 850mm, with roller diameters... ΦThe 600mm mark clearly defines the overall positioning boundary of the roller system, ensuring a perfect match with the installation space reserved in the top-level layout. Cooling system constraints: The height of the upper water collection pipe from the rolling centerline is marked as 277mm, the water collection tank as 270mm from the centerline, and the lower water collection pipe as 866mm from the bottom elevation reference. The horizontal distances between the water collection pipes and the roller system (e.g., 475mm, 360mm) are also marked to ensure the relative positions of the cooling system and the roller system meet process requirements. Interface constraints: The initial position references for the interfaces of the cooling manifold, water collection tank, etc., are clearly defined in the diagram, directly connecting to the interface data sharing pool in the PLM system. Designers of adjacent equipment can directly read this reference data without repeated manual verification of the drawings. This schematic diagram serves as a rigid constraint basis for detailed equipment modeling. The responsible designer conducts modeling according to the references and dimensional constraints in the diagram, and the position and dimensions of all components must not exceed the boundaries defined by the top-level constraints. When the top-level references (such as the rolling line elevation and equipment center distance) are adjusted, all related dimensions in the diagram can be automatically and synchronously updated through parametric driving, thereby driving the linkage adjustment of the equipment model's dimensions and position, ensuring the consistency of the entire design data process.

[0034] Parametric modeling technology is used to establish a dynamic relationship between the component dimensions in the equipment-level layout and the layout coordinate reference. The layout coordinate reference is used as the global origin of the entire assembly line, and the assembly positioning of each device is completed according to the spatial position reference of each device.

[0035] Specifically, parametric modeling technology is used to establish dynamic associations and complete assembly positioning. A correlation formula is established between the vertical dimensions of components and the layout coordinate datum in the equipment-level layout, allowing the vertical dimensions to automatically update as the datum plane changes. Simultaneously, the spatial position datum of each device is bound to the layout coordinate datum, enabling the device position to automatically move as the datum changes. Using the layout coordinate datum as the origin of the global coordinate system for the entire assembly line, the positioning datum points in the equipment-level skeleton of each device are aligned with its spatial position datum and converted into global coordinate values. Based on these values, each device is placed in its corresponding position, completing the entire assembly line.

[0036] The collaborative design method for hot strip mill production lines in this embodiment defines the planar relationships, interface constraints, and layout coordinate references of equipment through a top-level layout skeleton. All equipment generates equipment-level layouts within this framework, and the interfaces in the equipment-level layouts are required to match the top-level interface constraints. This fundamentally avoids dimensional conflicts that are difficult to eliminate even with manual verification in traditional designs, such as misalignment of adjacent mill roll gaps and mismatched roller table elevations. Furthermore, using the top-level layout skeleton as the sole data source, each design node determines the spatial location reference of the equipment based on it, and dynamically associates the equipment-level layout with the planar relationships and coordinate references in the skeleton. This ensures that equipment modeling remains consistent with the overall production line layout. Tasks are distributed through the PLM system, and permissions are configured for design nodes and their adjacent nodes. After the design is completed, interface data is automatically imported into a shared pool. Adjacent nodes only have read permissions and no modification permissions, ensuring data security while allowing equipment managers to obtain interface information of adjacent equipment in real time. When a change occurs to a piece of equipment and affects adjacent equipment, interference checks and associated designs in the 3D software can be automatically triggered and pushed, eliminating the need for repeated transfer of drawings and manual verification in traditional methods, significantly shortening the design cycle and reducing change costs. Meanwhile, parametric modeling technology is used to establish a correlation formula between component dimensions and layout coordinate references, and the equipment spatial position references are bound to the layout coordinate references. This ensures that once the layout references are adjusted, the dimensions and positions of all equipment are automatically updated synchronously, ensuring that the entire line design always meets the process specifications and avoiding inconsistencies caused by design iterations.

[0037] In summary, this embodiment significantly improves the design accuracy and efficiency of hot strip rolling production lines by unifying design benchmarks through top-level constraints, achieving hierarchical collaboration to enable interoperability and data sharing, driving dynamic synchronization of dimensions and positions through parameter association, and conducting closed-loop verification throughout the entire process. It overcomes the inherent defects of traditional decentralized design, such as insufficient collaboration, data fragmentation, and repeated changes.

[0038] Optionally, establishing a top-level layout framework based on process specifications and digital twin technology includes: The associated dimensions between each of the devices and the positioning dimensions of each device relative to the production reference are determined according to the process specifications. Based on digital twin technology, a planar layout is drawn for the shape of each device and the center lines in three directions to build an initial skeleton of the device. The initial skeleton of the device includes the spatial position reference points and / or reference lines of each device. Using the associated dimensions and the positioning dimensions as constraints, adjust the position reference of each device in the initial skeleton of the equipment until the relative position between each device satisfies the associated dimensions and the position of each device relative to the production reference satisfies the positioning dimensions. The adjusted skeleton, which includes the position reference of each of the devices, is used as the top-level layout skeleton.

[0039] Specifically, when establishing the top-level layout framework, the associated dimensions between each piece of equipment are first determined according to the process specifications of the hot strip mill production line. These dimensions include the center distance between adjacent mills, the length of the roller conveyor transition section, and the positioning dimensions of each piece of equipment relative to production references, such as the rolling centerline and the plant elevation reference. Then, based on digital twin technology, a planar layout of the shape and centerlines in three directions (length, width, and height) of each piece of equipment is drawn in a 3D design environment, thus constructing the initial equipment framework. This initial framework includes spatial position reference points for each piece of equipment, such as the intersection of roller centerlines and / or reference lines, such as the rolling centerline. Next, using the aforementioned associated dimensions and positioning dimensions as constraints, the position references of each piece of equipment in the initial framework are iteratively adjusted until the relative positions between each piece of equipment satisfy the associated dimensions (e.g., the center distance between adjacent mills reaches a set value) and the position of each piece of equipment relative to the production references satisfies the positioning dimensions (e.g., the mill centerline coincides with the rolling centerline). Finally, the adjusted complete framework, including the position references of each piece of equipment, is output as the top-level layout framework. This framework is subsequently used to establish assembly relationships with the models of each piece of equipment.

[0040] In this optional embodiment, the associated dimensions between each piece of equipment and their positioning dimensions relative to the production baseline are predetermined by the process specifications. The equipment outline and centerline planar layout are drawn using digital twin technology to form an initial skeleton. The associated dimensions and positioning dimensions are then used as constraints to iteratively adjust the equipment position baseline until both the relative and absolute positions meet the design requirements. Finally, a top-level layout skeleton containing the position baselines of all equipment is output. Thus, a unified spatial constraint baseline is established at the very upstream of the production line design, fundamentally avoiding the interface dimension inconsistencies such as roller gap connection deviations and roller conveyor elevation mismatches caused by the independent positioning of each piece of equipment in traditional decentralized design. At the same time, the equipment planar relationships, interface constraints, layout coordinate baselines, and equipment list are integrated into the same skeleton, providing a single data source for subsequent task distribution, permission configuration, equipment-level layout generation, and parametric assembly. This eliminates the disconnect between production line layout and equipment modeling, thereby improving the accuracy and efficiency of collaborative design.

[0041] Optionally, based on the device list and the interface constraints, the design task is distributed to each design node through the PLM system, and permissions are configured for the design nodes and adjacent design nodes. After the permission configuration of the design nodes and adjacent design nodes is completed, an interface data sharing pool is constructed, including: According to the equipment list, the design task for each of the equipment is distributed to the corresponding design node in the PLM system; Based on the interface constraints, determine the interface correspondence between adjacent devices; Based on the interface correspondence, each design node is configured with read and write permissions for its corresponding device, and adjacent design nodes are configured with read permissions for the interface data of that device. After the permissions of the design node and the adjacent design nodes are configured, the interface data generated by each device is aggregated into the shared pool to obtain the interface data shared pool.

[0042] Specifically, in the process of task distribution, permission configuration, and interface data sharing pool construction, the design tasks of each device are first distributed to the corresponding design nodes in the PLM system (e.g., Teamcenter) based on the equipment list in the top-level layout skeleton. In practice, the chief designer compiles the equipment list for the entire production line in Teamcenter and submits it for review. After the review is approved, the system automatically assigns the design tasks of each device to the corresponding responsible designer, who can then directly carry out the design in the integrated 3D software. Then, based on the interface constraints, i.e., the size, position, and matching requirements of the interfaces between adjacent devices, the interface correspondence between adjacent devices is determined. For example, the matching rules between the exit roller table interface of finishing mill F1 and the entrance roller table interface of mill F2 are clarified.

[0043] Based on this interface mapping, read and write permissions are configured for each design node and its corresponding device. This means the responsible designer has complete control over the device they are responsible for, while also granting adjacent design nodes read permissions for the device's interface data; designers of adjacent devices can only view the interface data but cannot modify it. Furthermore, dedicated designers have read permissions for all devices within their area, and the lead designer has read permissions for all devices across the entire line.

[0044] After the permissions of all design nodes and adjacent nodes are configured, each design node performs equipment design in the 3D software. During the design process, the interface data generated by each device, such as the hydraulic cylinder interface position, cooling water interface size, and dry oil point coordinates, are collected into a shared pool, thus obtaining the interface data shared pool. After that, piping designers do not need to collect all mechanical drawings as in traditional design, but can directly obtain interface data through this shared pool for piping design, realizing efficient data sharing and collaboration.

[0045] In this optional embodiment, the design tasks in the equipment list are automatically distributed to each design node through the PLM system, avoiding errors and inefficiencies caused by manual allocation. The interface correspondence between adjacent devices is determined based on interface constraints, and read / write permissions are configured for each design node to its corresponding device, and read permissions for the interface data of adjacent design nodes are configured only for that device. At the same time, the hierarchical read permissions of the regional head and chief designer are supplemented, which not only ensures the integrity and security of the design data, but also realizes the transparent communication of interface information between adjacent devices, eliminating the need for manual repeated transfer of drawings for verification. After the permission configuration is completed, the interface data sharing pool is built, which enables the interface data generated by each device to be automatically aggregated. Downstream professionals such as piping can directly obtain the required interface data from the sharing pool, which completely changes the inefficient mode of traditional design where piping designers need to collect all mechanical designer drawings one by one. When a device is changed and affects adjacent devices, because the permission configuration has clearly defined data access rules and the data in the sharing pool is available in real time, combined with the interference check and related design push mechanism of the 3D software, the change notification can be automatically triggered, which significantly shortens the design iteration cycle and reduces change costs.

[0046] Optionally, each design node determines the spatial location reference of the equipment corresponding to that design node in the production line based on the equipment planar relationship, including: Extract the planar positioning reference of the equipment corresponding to the design node from the top-level layout skeleton. The planar positioning reference includes the intersection of the equipment centerline and / or the intersection of the roller centerline. The coordinate values ​​of the planar positioning reference under the layout coordinate reference are used as the spatial position reference of the equipment corresponding to the design node.

[0047] Specifically, when determining the spatial position reference of the corresponding equipment in the production line, each design node extracts the planar positioning reference of the equipment from the established top-level layout skeleton. The planar positioning reference is specifically manifested as the intersection of the equipment center lines, such as the intersection of the center line of the rolling mill stand and the rolling center line or the intersection of the roller center lines, such as the intersection of the roller conveyor center line and the equipment center line. These intersections have been defined as points or lines in the process of constructing the top-level layout skeleton.

[0048] Then, using the layout coordinate reference defined in the top-level layout skeleton, namely the origin and axis of the global coordinate system, as a reference, the coordinate values ​​of the plane positioning reference in the global coordinate system are extracted and used as the spatial position reference of the equipment in the production line.

[0049] For example, for a roughing mill, the coordinates (X, Y, Z) of the intersection of its roll centerline and the rolling centerline are the positioning origin of the equipment. This origin is used as the reference for subsequent equipment-level skeleton modeling. Thus, each piece of equipment obtains a unique spatial position reference in a unified coordinate system, ensuring accurate and coordinated positioning of each piece of equipment within the entire production line.

[0050] In this optional embodiment, each design node directly extracts the intersection of the equipment centerline or the intersection of the roller centerline from the top-level layout skeleton as a planar positioning reference, and uses its coordinate value under the unified layout coordinate reference as the spatial position reference of the equipment. This ensures that all equipment on the entire hot rolling production line obtains a unique spatial position based on the same global coordinate system. This avoids problems such as coordinate deviation, roller gap misalignment, and inconsistent roller table elevation caused by the independent setting of origin for each piece of equipment in traditional decentralized design. It ensures that the spatial position of each piece of equipment in the production line is accurate and coordinated with each other. At the same time, it provides a clear positioning origin for the subsequent establishment of the equipment-level skeleton, so that the equipment-level layout can be precisely aligned with the top-level layout skeleton, thereby ensuring the design consistency and assembly feasibility from the overall to the local.

[0051] Optionally, generating the device-level layout of the device corresponding to the design node based on the interface data in the interface data sharing pool and the interface constraints includes: Using the spatial location reference as the positioning origin of the device, a device-level skeleton is established, which includes the centerline and outer contour of the device. The initial position and initial size of each interface on the device are determined based on the interface constraints. Based on the interface data of adjacent devices in the interface data sharing pool, the initial position is adjusted to obtain the interface position of the device that matches the interface of the adjacent devices; Associating the interface location and the initial size with the device-level skeleton generates the device-level layout for the device.

[0052] Specifically, when generating the equipment-level layout, the previously determined spatial location benchmark of the equipment is used as the positioning origin to establish the equipment-level skeleton. This skeleton includes the equipment's centerline, such as the centerline of the rolling mill stand, and its outer contour, such as the basic geometric dimensions like the width and height of the frame. Then, based on the interface constraints in the top-level layout skeleton, the initial positions of each interface on the equipment are determined one by one, such as the mounting surface coordinates and initial dimensions of the hydraulic cylinder interface, such as the diameter of the cooling water pipe and the diameter of the dry oil point. Next, the interface data of adjacent equipment, such as the interface coordinates of adjacent rolling mills, is read from the interface data sharing pool, and the aforementioned initial positions are fine-tuned. For example, the coordinates of the equipment's interface are aligned with those of the adjacent equipment interface to ensure a precise spatial match, while the interface dimensions usually remain unchanged from their initial values. Finally, the adjusted interface positions and initial dimensions are associated with the equipment-level skeleton through parameterization, thus completing the generation of the complete equipment-level layout of the equipment.

[0053] During this process, if a device undergoes a design change, the interference check function of the 3D software will automatically detect interface conflicts and trigger a push process through the associated design to notify the relevant design nodes to synchronize and update.

[0054] In this optional embodiment, a device-level skeleton is established with a unified spatial location benchmark as the positioning origin. The initial position and size of each interface are predetermined according to interface constraints. Then, the device's own interface position is adaptively adjusted using the actual interface data of adjacent devices in the interface data sharing pool. This ensures that the interfaces between the device and adjacent devices are precisely matched in space, thereby avoiding problems such as roller gap connection deviation and interface misalignment caused by independent design of each device and manual verification in traditional design. The interface size remains unchanged with the initial value determined by the process specification, which not only meets the design requirements but also reduces unnecessary changes. After associating the adjusted interface position and initial size with the device-level skeleton, a device-level layout containing complete interface information is formed, providing a reliable data foundation for subsequent parametric modeling and whole-line assembly. When any device changes, the interface data synchronization based on the shared pool and the interference check and push mechanism of the 3D software can automatically trigger update notifications for adjacent devices, significantly reducing design iteration costs and communication overhead, thereby achieving efficient and accurate parallel collaborative design.

[0055] Optionally, the step of employing parametric modeling technology to dynamically link the component dimensions in the device-level layout with the layout coordinate reference includes: By using the parametric modeling technique, a correlation formula is established between the vertical dimensions of components in the device-level layout and the layout coordinate reference, so that the vertical dimensions are automatically adjusted as the layout coordinate reference changes. Based on the aforementioned correlation formula, a parametric constraint relationship is established between the spatial position reference of each device and the layout coordinate reference, so that the position of the device moves automatically as the layout coordinate reference changes.

[0056] Specifically, when establishing dynamic associations using parametric modeling technology, firstly, parametric modeling software (such as NX or SolidWorks) is used to define driveable dimensional variables for each component in the equipment-level layout. Then, a relationship formula is established between the vertical dimensions of the components, such as the height of the mill window and the length of the roller stand column, and the reference plane where the layout coordinate datum is located. For example, the height of the mill window is set as Z value of the elevation datum plane in the layout coordinate datum + process compensation amount. This ensures that when the elevation in the layout coordinate datum changes, all vertical dimensions that depend on the datum are automatically recalculated and the model is updated according to the formula. Then, based on the aforementioned correlation formula, a parametric constraint relationship is further established between the spatial position reference of each device—that is, the global coordinates of the previously determined intersection of the device centerline or the roller centerline—and the layout coordinate reference. For example, the X, Y, and Z coordinates of the device positioning origin are bound to the origin offset of the layout coordinate reference, forming a constraint equation such as Device Origin X = Layout Coordinate Reference Origin X + Design Offset. This allows the 3D model position of the device to move with the layout coordinate reference. It automatically and synchronously moves when the entire production line is translated or its elevation is adjusted, without the need for manual repositioning.

[0057] In this optional embodiment, by establishing a correlation formula between the vertical dimensions of components in the equipment-level layout and the layout coordinate datum, the component dimensions can be automatically adjusted as the layout coordinate datum changes. This avoids the tedious work of modifying the dimensions of each component individually due to datum changes in traditional design. Simultaneously, based on this correlation formula, a parametric constraint relationship is further established between the spatial position datum of each device and the layout coordinate datum, enabling the device position to move automatically as the layout coordinate datum changes. This achieves fully parametric linkage from the top-level datum to the bottom-level geometry. When the production line layout needs overall adjustment, such as elevation changes or production line translation, the dimensions and positions of all devices are automatically updated without manual modification. This ensures the consistency of the entire line design, significantly reduces the workload and error rate of design iterations, and improves the design flexibility and response speed of the hot rolling mill production line.

[0058] Optionally, the step of using the layout coordinate reference as the global origin of the entire assembly line and completing the assembly positioning of each device according to the spatial position reference of each device includes: Align the positioning reference points in the device-level skeleton of each device with the corresponding spatial position references; Using the layout coordinate reference as the origin of the global coordinate system, the coordinates of the positioning reference point of each device are converted into coordinate values ​​in the global coordinate system; Based on the converted coordinate values, the device-level skeleton of each device is placed at the corresponding position in the global coordinate system, thus completing the assembly and positioning of each device.

[0059] Specifically, the predefined positioning reference points in the equipment-level skeleton of each device, such as the intersection of the device centerline and the roller centerline, are aligned with the corresponding spatial position reference of the device, i.e., the global coordinate values ​​previously extracted from the top-level layout skeleton, in the model space to ensure that the origin of the local coordinate system of the equipment-level skeleton coincides with the global spatial position reference. Then, using the layout coordinate reference defined in the top-level layout skeleton as the origin of the global coordinate system for the entire line assembly, the coordinates of the positioning reference points of all devices are transformed from their respective local coordinate systems to this global coordinate system to obtain unified global coordinate values. Finally, based on the transformed global coordinate values, the complete equipment-level skeleton of each device, including its centerline, outline, and associated interface positions and dimensions, is precisely placed in the corresponding position in the global coordinate system, thereby completing the assembly and positioning of all devices in the entire hot continuous rolling production line, so that each device forms an accurate relative positional relationship in global space, providing a reliable digital model foundation for subsequent interference checks, process simulation, and production line construction.

[0060] In this optional embodiment, by aligning the positioning reference point in the equipment-level skeleton of each device with its corresponding spatial position reference, and performing coordinate transformation with a unified layout coordinate reference as the global origin, each device is ultimately placed precisely in its corresponding position in the global coordinate system, thereby achieving precise virtual assembly of the entire hot rolling production line in the digital environment. This process ensures that the relative positional relationship of all devices in the global space fully conforms to the design requirements of the top-level layout skeleton, avoiding positional deviations and collision conflicts caused by inconsistent coordinate references in traditional assembly. At the same time, since the interface position and size information are already associated in the equipment-level skeleton of each device, interference checks, process simulations, and production line verification can be performed directly after assembly without additional manual alignment or adjustment, significantly improving assembly efficiency and reliability.
