Description

Technical Field

[0001] This invention relates to digital construction technology, and more particularly to a digital delivery management system and method for prefabricated buildings. Background Technology

[0002] In the process of disassembling and delivering building components, the efficient matching of component characteristics with external constraints is crucial.

[0003] Traditional manual dismantling methods rely on experience to formulate solutions, making it difficult to systematically analyze the quantitative relationship between component characteristics such as geometry and structural properties and external constraints such as transport channel dimensions and equipment specifications. This results in dismantling solutions that are inefficient, have high safety risks, and cause significant material waste. For example, when the length of a large building component exceeds external limits, manually planned dismantling paths may not avoid critical structural areas or may fail to evenly distribute unit sizes, thereby affecting the safety and efficiency of subsequent delivery processes.

[0004] Therefore, how to efficiently disassemble and deliver building components while taking into account external constraints has become an urgent problem to be solved. Summary of the Invention

[0005] This invention provides a modular building digital delivery management system and method that can efficiently disassemble and deliver building components in conjunction with external constraints.

[0006] A first aspect of the present invention provides a method for digital delivery management of prefabricated buildings, comprising:

[0007] The components to be split are determined based on the comparison results of scene parameters and component characteristics.

[0008] Based on the component features of the component to be split, a splitting template is matched, and the initial splitting parameters of the component to be split are generated according to the splitting path of the splitting template.

[0009] When the initial splitting parameters do not meet the scenario parameters, the rule combination mechanism is triggered to combine multiple splitting paths to obtain a combined path;

[0010] The combined path generates combined splitting parameters, which are sent to the execution device to drive the execution device to perform splitting operations and associate the physical components and digital models of the components to be split to obtain delivery data.

[0011] Optionally, in one possible implementation of the first aspect, the component to be split is determined based on the specification comparison results of scene parameters and component characteristics, including:

[0012] The path parameters and hoisting parameters are obtained by parsing the scene parameters, and the component features include the specifications of each building component;

[0013] Compare the minimum path width corresponding to the specifications and path parameters of each building component with the maximum hoisting specifications corresponding to the hoisting parameters;

[0014] Building components with specifications greater than the minimum path width and / or specifications greater than the maximum hoisting specifications are identified as components to be disassembled.

[0015] Optionally, in one possible implementation of the first aspect, matching a splitting template based on the component features of the component to be split, and generating initial splitting parameters for the component to be split according to the splitting path of the splitting template, includes:

[0016] Based on the component characteristics of the component to be split, the structural functional attributes of the component to be split are obtained. When the structural functional attribute is a load-bearing attribute, a rule watermark template is matched for the component to be split, and the component to be split is split according to the rule splitting path of the rule watermark template to obtain the first splitting parameter.

[0017] When the structural property is a non-load-bearing property, an irregular watermark template is matched for the component to be split, and the component to be split is split according to the irregular splitting path of the irregular watermark template to obtain the second splitting parameter.

[0018] The initial splitting parameters include a first splitting parameter and a second splitting parameter; the splitting template includes a regular watermark template and an irregular watermark template; and the splitting path includes a regular splitting path and an irregular splitting path.

[0019] Optionally, in one possible implementation of the first aspect, when the structural functional attribute is a load-bearing attribute, a rule watermark template is matched for the component to be split, and the component to be split is split according to the rule splitting path of the rule watermark template to obtain a first splitting parameter, including:

[0020] Obtain the first multi-view from the perspective of the specification parameters corresponding to the scene parameters of the component to be split, and retrieve the rule watermark template to overlay on the first multi-view. The first multi-view includes a front view, a top view, and a side view.

[0021] Determine the first splitting direction in each of the first multi-views, generate a rule splitting path based on the rule watermark template in the first splitting direction, split the component to be split into multiple first splitting units according to the rule splitting path, and obtain the first splitting parameters based on the first splitting units.

[0022] Optionally, in one possible implementation of the first aspect, a first splitting direction is determined in each of the first multi-views, a rule splitting path is generated based on the rule watermark template along the first splitting direction, and the component to be split is split into multiple first splitting units according to the rule splitting path, including:

[0023] The vertical and horizontal directions in each of the first multi-views are determined as the first splitting directions;

[0024] Based on the center position of each of the first multi-views, a rule-based splitting path parallel to the first splitting direction is generated, and the real-time specifications of the first splitting unit after being divided based on the rule-based splitting path corresponding to each of the first multi-views are obtained.

[0025] Based on the real-time specifications, the path sequence is obtained by splitting the path corresponding to each first multi-view according to the rules from smallest to largest.

[0026] Based on the path sequence, the rule splitting path is sequentially superimposed to divide a majority of components to be split into multiple first splitting units, until the specification of the first splitting unit is less than the specification parameter corresponding to the scene parameter, at which point the superposition of the rule splitting path stops.

[0027] Optionally, in one possible implementation of the first aspect, when the structural attribute is a non-load-bearing attribute, an irregular watermark template is matched for the component to be split, and the component to be split is split according to the irregular splitting path of the irregular watermark template to obtain a second splitting parameter, including:

[0028] Obtain the second multi-view from the perspective of the specification parameters corresponding to the scene parameters of the component to be split, and retrieve the irregular watermark template to overlay on the second multi-view;

[0029] Determine the second splitting direction in each of the second multi-views, generate an irregular splitting path based on the irregular watermark template in the second splitting direction, split the component to be split into multiple second splitting units according to the irregular splitting path, and obtain the second splitting parameters based on the second splitting units.

[0030] Optionally, in one possible implementation of the first aspect, a second splitting direction is determined in each of the second multi-views, an irregular splitting path is generated based on the irregular watermark template in the second splitting direction, and the component to be split is split into multiple second splitting units according to the irregular splitting path, including:

[0031] Connect the component outline points that are furthest apart in each of the second multi-views to obtain the reference direction, and determine the direction perpendicular to the reference direction as the second splitting direction;

[0032] Based on the center position of each of the second multi-views, an irregular splitting path parallel to the second splitting direction is generated, and the component to be split is split into multiple second splitting units based on the irregular splitting path.

[0033] Optionally, in one possible implementation of the first aspect, when the initial splitting parameters do not satisfy the scenario parameters, a rule combination mechanism is triggered to combine multiple splitting paths to obtain a combined path, including:

[0034] When the initial splitting parameters of the component to be splitting with load-bearing attributes do not meet the specification parameters corresponding to the scenario parameters, the user-defined auto-defined path is obtained, and the auto-defined path and the rule splitting path are superimposed to obtain the first combined path.

[0035] When the initial splitting parameters of the component to be split, which is not load-bearing, do not meet the specification parameters corresponding to the scene parameters, a supplementary path is generated according to the irregular splitting path, and the irregular splitting path and the supplementary path are superimposed to obtain a second combined path.

[0036] The combined path includes a first combined path and a second combined path, and the split path further includes an automatically defined path and a supplementary path.

[0037] Optionally, in one possible implementation of the first aspect, when the initial splitting parameters of the component to be split (which has a non-load-bearing attribute) do not meet the specification parameters corresponding to the scene parameters, a supplementary path is generated based on the irregular splitting path, including:

[0038] Using the farthest component outline point in the second view corresponding to the non-load-bearing component to be split as a reference, a baseline parallel to the second splitting direction is generated, and a supplementary path is generated based on the baseline and the centerline direction of the second splitting direction.

[0039] A second aspect of the present invention provides a modular building digital delivery management system, comprising:

[0040] The comparison module is used to determine the components to be split based on the specification comparison results of scene parameters and component characteristics;

[0041] The matching module is used to match a splitting template based on the component features of the component to be split, and generate initial splitting parameters for the component to be split according to the splitting path of the splitting template.

[0042] The combination module is used to trigger a rule combination mechanism to combine multiple splitting paths to obtain a combined path when the initial splitting parameters do not meet the scenario parameters.

[0043] The association module is used to generate combination and splitting parameters based on the combination path and send them to the execution device to drive the execution device to perform splitting operations, and associate the physical components and digital models of the components to be split to obtain delivery data.

[0044] The beneficial effects of this invention are as follows:

[0045] 1. By accurately comparing scene parameters and component characteristics, this invention can identify components that need to be split in advance, thereby achieving automated and accurate screening of components to be split and improving screening efficiency.

[0046] 2. This invention, by matching a suitable splitting template, can formulate an optimized initial splitting scheme based on the specific characteristics of the components. This not only ensures the safety and feasibility of the splitting process but also improves the efficiency and quality of the splitting, reducing unnecessary resource waste and time consumption.

[0047] 3. This invention utilizes a trigger rule combination mechanism to rationally combine and adjust multiple splitting paths, generating a splitting scheme that comprehensively meets the actual needs of complex scenarios. This ensures that after splitting, each unit can smoothly pass through multiple construction stages in terms of size and shape, improving the adaptability and feasibility of the splitting scheme, reducing rework caused by unreasonable schemes, and improving building management efficiency.

[0048] 4. This invention links the disassembly process with a digital model and acquires delivery data, enabling digital management and full-process traceability of the entire disassembly process. This not only helps improve the controllability and transparency of the construction process but also facilitates subsequent quality inspections, maintenance, and overall project management. Through the digital model and delivery data, construction personnel can clearly understand the disassembly process, status, and related information of each component, promptly identify and resolve potential problems, and ensure the smooth delivery of the project.

[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] See Figure 1 This is a schematic diagram of an application scenario provided by an embodiment of the present invention. The present invention can intelligently disassemble building components in complex environments. By integrating scene parameter perception and component feature analysis, the building components can be flexibly disassembled. When a single disassembly strategy cannot meet the requirements of the scenario, a multi-strategy combination mechanism will be triggered for disassembly. Furthermore, the disassembled building components are associated with digital modules, thereby achieving efficient collaboration of building components from disassembly and assembly to delivery, and improving the management efficiency of building components.

[0054] See Figure 2 This is a flowchart illustrating a digital delivery management method for modular buildings provided in an embodiment of the present invention. Figure 2 The execution entity of the method shown can be a software and / or hardware device. The execution entity of this application can include, but is not limited to, at least one of the following: user equipment, network equipment, etc. User equipment can include, but is not limited to, computers, smartphones, personal digital assistants (PDAs), and the aforementioned electronic devices. Network equipment can include, but is not limited to, a single network server, a server group consisting of multiple network servers, or a cloud based on cloud computing consisting of a large number of computers or network servers. Cloud computing is a type of distributed computing, consisting of a super virtual computer composed of a group of loosely coupled computers. This embodiment does not limit this. Steps S1 to S4 are detailed as follows:

[0055] S1. Determine the components to be split based on the comparison results of scene parameters and component characteristics.

[0056] Understandably, different scenarios and components have their own unique conditions and requirements during construction. Accurately comparing scenario parameters with component specifications allows for the precise identification of components that, due to factors such as size, shape, or weight, do not meet current construction conditions and require disassembly. For example, in old residential area renovation projects, there may be narrow alleyways with obstacles such as utility poles and trees. Disassembly may require consideration of these factors to ensure the safe transport of components into the community. Therefore, by accurately comparing scenario parameters and component characteristics, components requiring disassembly can be identified in advance, laying the foundation for efficient and safe construction.

[0057] Scene parameters are various specific data and conditions of the building construction environment, which can be collected by using drones equipped with LiDAR scanning, vehicle-mounted sensor arrays, and other equipment. These parameters include the width, height, turning radius of the transport channel, and the distribution of obstacles. These parameters directly affect whether the components can be transported to the designated location smoothly. For example, the maximum lifting size and lifting capacity of the hoisting equipment determine how the components can be operated and moved during construction. These factors have an important limiting effect on the on-site layout of the components and the construction operation space.

[0058] Component characteristics refer to the various properties inherent in a building component. These include material characteristics and geometric features, which can be obtained through BIM model import or industrial CT scanning. Geometric features can reflect the component's shape, size, and surface curvature; material characteristics can indicate the component's load-bearing properties, strength grade, and separability. Components to be separated are building components that meet the separability criteria.

[0059] By using precise comparison methods, it is possible to achieve automated and accurate screening of components to be split, thereby improving screening efficiency.

[0060] Based on the above embodiments, step S1 can be implemented in the following ways:

[0061] The scene parameters are parsed to obtain path parameters and hoisting parameters. The component features include the specifications of each building component. The minimum path width corresponding to the specifications of each building component and the path parameters are compared with the maximum hoisting specifications corresponding to the hoisting parameters. Building components with specifications greater than the minimum path width and / or specifications greater than the maximum hoisting specifications are identified as components to be split.

[0062] By quantitatively comparing scenario constraints and component specifications, building components that need to be disassembled due to exceeding size limits can be accurately identified, reducing construction obstruction or safety risks caused by blind transportation.

[0063] Route parameters include various parameters related to the transportation route, such as width and turning radius. Lifting parameters include various parameters related to lifting, such as lifting specifications and load capacity.

[0064] In practical applications, the minimum path width of the transport route can be extracted from the drone scanning data, the maximum lifting specifications can be obtained from the lifting equipment manual, and the dimensions of each component can be exported from the BIM model. If the component width is greater than the minimum path width, or any dimension of length, width, or height is greater than the corresponding dimension of the maximum lifting specification, it is marked as needing to be split.

[0065] Through the above steps, precise matching of scenarios and components can be achieved through digital means.

[0066] S2, Match the splitting template based on the component features of the component to be split, and generate the initial splitting parameters of the component to be split according to the splitting path of the splitting template.

[0067] Different components have different characteristics, and therefore require different splitting methods. By matching a suitable splitting template, an optimized initial splitting scheme can be developed based on the specific characteristics of the components. This not only ensures the safety and feasibility of the splitting process but also improves the efficiency and quality of the splitting, reducing unnecessary resource waste and time consumption.

[0068] A modular template is a pre-designed disassembly strategy for different types of components. For load-bearing components, a regular template is typically used. The disassembly path of this template is mainly limited to the vertical or horizontal direction to ensure that the main load-bearing structure of the component is not damaged during the disassembly process. For example, for concrete beams, disassembly is generally carried out in a horizontal direction perpendicular to the beam's length or parallel to the beam's cross-section. For non-load-bearing components, a flexible template is used, which supports a wider variety of disassembly methods, including arbitrary angles, curves, or combinations of polylines. This flexibility is suitable for various irregularly shaped non-load-bearing components, such as irregularly shaped glass curtain walls.

[0069] The initial splitting parameters are calculated based on the splitting template and the specific dimensions of the component to be split, resulting in the initial unit size and quantity after splitting. For example, for a 6m × 4m rectangular load-bearing component, if a regular template is used for splitting, it may initially be split into 3m × 4m units, with a unit quantity of 2.

[0070] Based on the above embodiments, step S2 can be implemented in the following ways:

[0071] S21, obtain the structural functional attributes of the component to be split based on the component characteristics of the component to be split. When the structural functional attribute is a load-bearing attribute, match a rule watermark template for the component to be split and split the component to be split based on the rule splitting path of the rule watermark template to obtain the first splitting parameter.

[0072] Specifically, the structural functional attributes of the component to be disassembled can first be determined by analyzing its geometric characteristics (such as whether it contains reinforcing steel and its cross-sectional dimensions) and material characteristics (such as concrete strength grade and steel type). If the component is load-bearing, the regular watermark template matching mechanism is triggered. The regular watermark template is a standardized disassembly scheme pre-designed for load-bearing components. Its core feature is that the disassembly path is strictly limited to the vertical or horizontal direction to avoid damaging the main stress system of the component.

[0073] By identifying the structural and functional attributes of components based on their characteristics, differentiated disassembly can be achieved. This ensures that load-bearing components still meet structural stability requirements after disassembly, while non-load-bearing components can be flexibly disassembled to improve assembly convenience. Standardized disassembly of load-bearing components using preset rule-based watermark templates ensures that each part still conforms to engineering mechanics specifications after disassembly, reducing the risk of structural failure due to non-standard disassembly.

[0074] Structural functional attributes refer to whether a component bears load transfer within a building structure, and are divided into load-bearing attributes (such as beams, columns, and load-bearing walls) and non-load-bearing attributes (such as partition walls, curtain walls, and decorative components). The regular watermark template is a splitting template specifically designed for load-bearing components, containing standardized splitting paths (i.e., regular splitting paths) to ensure splitting compliance. The first splitting parameter is the initial splitting data generated for the load-bearing component, including unit geometry dimensions, cutting equipment parameters, etc.

[0075] In some embodiments, step S21 can be implemented through the following steps:

[0076] S211, obtain the first multi-view under the perspective of the specification parameters corresponding to the scene parameters of the component to be split, and retrieve the rule watermark template to be superimposed on the first multi-view. The first multi-view includes a front view, a top view and a side view.

[0077] Understandably, when a certain specification parameter (such as width, height, or length) of the component to be split exceeds the scene limit, extracting the views directly related to the parameter exceeding the limit (such as the width corresponding to the front view, the height corresponding to the side view, and the length corresponding to the top view) for key analysis can reduce redundant operations in full view processing. At the same time, by overlaying rule watermark templates, the splitting rules of the load-bearing component can be accurately mapped to the key views, ensuring that the splitting path meets the scene size requirements without damaging the load-bearing structure of the component.

[0078] The first multi-view consists of one or more views that exceed the specification parameters. For example, if both the width and height of a component exceed the limits, the first multi-view consists of a front view and a side view.

[0079] S212, determine the first splitting direction in each of the first multi-views, generate a rule splitting path based on the rule watermark template in the first splitting direction, split the component to be split into multiple first splitting units according to the rule splitting path, and obtain the first splitting parameters based on the first splitting units.

[0080] In the over-limit view, the splitting direction is determined according to scene constraints and template rules, and a standardized splitting path is generated. The components are split in the over-limit dimension to obtain the first splitting parameter containing the geometric dimensions, which can provide precise instructions for automated cutting.

[0081] The first splitting direction is the direction in which the load-bearing component is split, and the first splitting unit is the basic component obtained after dividing the component according to the splitting path.

[0082] In some embodiments, a first splitting direction in each of the first multi-views can be determined by the following steps: generating a rule splitting path based on the rule watermark template in the first splitting direction; and splitting the component to be split into multiple first splitting units according to the rule splitting path, including:

[0083] The vertical and horizontal directions in each of the first multi-views are determined as the first splitting directions; a rule-based splitting path parallel to the first splitting direction is generated based on the center position of each of the first multi-views; the real-time specifications of the first splitting units after being divided by the rule-based splitting paths corresponding to each of the first multi-views are obtained; the rule-based splitting paths corresponding to each of the first multi-views are arranged in ascending order according to the real-time specifications to obtain a path sequence; multiple components to be split are divided by sequentially superimposing the rule-based splitting paths based on the path sequence to obtain multiple first splitting units until the specifications of the first splitting units are less than the specifications corresponding to the scene parameters, at which point the superposition of the rule-based splitting paths is stopped.

[0084] Understandably, for load-bearing components, the internal main reinforcement bars and other structural elements bear the primary load, and structural safety principles must be strictly followed when splitting them. The splitting paths in the vertical and horizontal directions are typically parallel or perpendicular to the distribution direction of the main reinforcement bars. This splitting method minimizes damage to the structural load-bearing system and reduces stress concentration caused by oblique splitting, thus reducing potential structural safety hazards. For example, in a front view, the vertical direction can be the Y-axis, i.e., perpendicular to the width; the horizontal direction can be the X-axis, parallel to the length.

[0085] Generating a regular splitting path starting from the center of the first multi-view allows for balanced component splitting. This ensures that the dimensions of each split unit are relatively uniform, preventing situations where one side has an excessively small or large remaining size, thus guaranteeing the regularity and standardization of the split units. After generating the path, obtaining the real-time specifications of the split units allows for timely understanding of the splitting effect; the real-time specifications represent the actual size data of the first split unit after splitting.

[0086] Arranging the rule-based splitting paths according to real-time specifications from smallest to largest determines the order of splitting operations. Prioritizing splitting paths that quickly meet scenario constraints for component size reduces unnecessary splitting steps and times, improving efficiency. For example, splitting smaller units first allows the overall component specifications to meet scenario parameter requirements more quickly, avoiding over-splitting or duplicate splitting in subsequent processes, thus saving time and resources, and reducing the risk of damage to the component structure from multiple splitting operations.

[0087] By sequentially stacking rules to split paths according to the path sequence, progressive refinement of the splitting process can be achieved. Components are split in stages, with unit specifications verified after each split to ensure that the splitting process gradually brings the component dimensions to meet scene parameter requirements while maintaining structural safety. Stacking stops when the specifications of the first split unit are smaller than the corresponding scene parameter specifications. This ensures that the split components meet construction requirements while preserving component integrity to the greatest extent possible, avoiding over-splitting. The path sequence is a sequential list formed by arranging the rule-based splitting paths corresponding to each first multi-view in ascending order of their real-time unit specifications after splitting.

[0088] Taking a concrete column as an example, its dimensions are 8m (length) × 3m (width) × 2m (height). The transportation path is limited to a width of 2.5m, and the hoisting equipment is limited to a height of 1.8m. Therefore, the front view (showing width) and the side view (showing height) become the first multiple views.

[0089] In the front view, the vertical direction is the Y-axis (perpendicular to the width), and the horizontal direction is the X-axis (parallel to the length); in the side view, the vertical direction is the Y-axis (perpendicular to the height), and the horizontal direction is the X-axis (parallel to the width).

[0090] In the front view, the beam is 3m wide and 2m high, with its center located at 1.5m in the width direction and 1m in the height direction. Based on this, a regular splitting path parallel to the vertical direction is generated from the center position 1.5m, splitting the width into 1.5m + 1.5m; simultaneously, a regular splitting path parallel to the horizontal direction is generated from the center position 1m, splitting the height into 1m + 1m. This results in four first splitting units with real-time dimensions of 1.5m (width) × 1m (height), 1.5m × 1m, 1.5m × 1m, and 1.5m × 1m, respectively. The width of 1.5m is still greater than the scene's 2.5m limit, while the height of 1m is less than the scene's 1.8m limit.

[0091] In the side view, the beam is 2m high and 3m wide, with its center located 1m above the ground and 1.5m below the ground. A regular splitting path parallel to the vertical direction is generated from the center (1m) to split the height into 1m + 1m; a regular splitting path parallel to the horizontal direction is generated from the center (1.5m) to split the width into 1.5m + 1.5m. The resulting four first splitting units have real-time dimensions of 1m (height) × 1.5m (width), with the height of 1m being less than the scene limit and the width of 1.5m being greater than the scene limit.

[0092] Since 1m (side view height specification) < 1.5m (front view and side view width specification), the path sequence is as follows: first execute the rule splitting path in the vertical direction (adjusting height) of the side view, then execute the rule splitting path in the horizontal direction (adjusting width) of the side view, and finally execute the rule splitting paths in the vertical and horizontal directions (further adjusting width) of the front view.

[0093] Based on the determined path sequence, the vertical path splitting in the side view is executed first. Since the height of the previously split side view is 1m, which is less than the scene limit of 1.8m, no further height adjustment is needed. Next, the horizontal path splitting in the side view is executed, generating a horizontal path from the new center position (0.75m in the width direction), splitting the width into 0.75m + 0.75m. At this point, the unit size in the side view direction is 0.75m (width) × 1m (height), and the width is less than the scene limit of 2.5m.

[0094] Then, the vertical rule-based splitting path in the front view is executed to further split the width. Since the previous width of the front view was 1.5m, a vertical path is generated again from the new center position of 0.75m to split the width into 0.75m + 0.75m; then, the horizontal rule-based splitting path in the front view is executed (if the height needs to be further adjusted), finally resulting in multiple first split units, all of which are smaller than the specifications corresponding to the scene parameters (width less than 2.5m, height less than 1.8m). At this point, the stacking of rule-based splitting paths is stopped.

[0095] By sequentially stacking split paths based on path sequences and stopping at appropriate times, precise splitting control can be achieved for complex components to be split.

[0096] S22, when the structural attribute is a non-load-bearing attribute, an irregular watermark template is matched for the component to be split, and the component to be split is split according to the irregular splitting path of the irregular watermark template to obtain the second splitting parameter.

[0097] The initial splitting parameters include a first splitting parameter and a second splitting parameter; the splitting template includes a regular watermark template and an irregular watermark template; and the splitting path includes a regular splitting path and an irregular splitting path.

[0098] If a component is determined to be non-load-bearing, an irregular watermark template will be matched. This type of template allows for flexible path splitting, including diagonal lines, curves, polylines, etc., at any angle, to adapt to the irregular outline of the component or the needs of complex scenarios.

[0099] The irregular watermark template is a split template designed for non-load-bearing components, supporting split paths at any angle with no strict directional restrictions. The irregular split path is a free split trajectory distinct from the vertical / horizontal directions. The second split parameter is the initial split data generated for non-load-bearing components.

[0100] In some embodiments, step S22 can be implemented through the following steps:

[0101] Obtain a second multi-view from the perspective of the specification parameters corresponding to the scene parameters of the component to be split. Retrieve an irregular watermark template and overlay it on the second multi-view. Determine the second splitting direction in each of the second multi-views. Generate an irregular splitting path based on the irregular watermark template in the second splitting direction. Split the component to be split into multiple second splitting units according to the irregular splitting path. Obtain the second splitting parameters based on the second splitting units.

[0102] For non-load-bearing components, since they do not bear structural loads, the disassembly flexibility is greater. Extracting multiple views from corresponding perspectives allows for focused directional analysis from key viewpoints, improving disassembly efficiency. Overlaying irregular watermark templates visualizes the flexible disassembly rules applicable to non-load-bearing components.

[0103] The second multi-view contains one or more views with out-of-limit specifications, distinguishing it from the "first multi-view" of load-bearing components, and specifically refers to the analysis perspective of non-load-bearing components. The second splitting direction is the non-fixed direction corresponding to the non-load-bearing components. The second splitting unit is the component part after being split along an irregular path.

[0104] In some embodiments, the step "determining a second splitting direction in each of the second multi-views, generating an irregular splitting path based on the irregular watermark template in the second splitting direction, and splitting the component to be split into multiple second splitting units according to the irregular splitting path" includes:

[0105] A reference direction is obtained by connecting the component outline points that are furthest apart in each of the second multi-views. The direction perpendicular to the reference direction is determined as the second splitting direction. An irregular splitting path parallel to the second splitting direction is generated based on the center position of each of the second multi-views. The component to be split is split into multiple second splitting units based on the irregular splitting path.

[0106] For non-load-bearing components, whose shapes may be complex, such as irregularly shaped glass curtain walls or irregular decorative components, a reference direction can be determined by connecting the farthest contour points in the view, and then taking its perpendicular direction as the splitting direction. This maximizes the use of component space, reduces unnecessary cutting, and ensures that the split units have relatively regular shapes, facilitating transportation and installation. The reference direction is the straight line formed by connecting the two farthest contour points in the second multi-view, serving as a reference axis for determining the splitting direction.

[0107] Generating a path parallel to the second splitting direction starting from the center of the view ensures that the splitting units are evenly distributed on the component, reducing the possibility of the remaining size on one side being too small or too large.

[0108] Taking a wavy glass curtain wall as an example, it presents an irregular curved outline in the front view. Measurements show that the distance between the top left and bottom right corners of the curtain wall is the greatest. Connecting these two points yields a reference direction (assumed to be a diagonal line from the top left to the bottom right). Subsequently, a direction perpendicular to this reference direction (i.e., a diagonal line from the bottom left to the top right) is determined as the second splitting direction. This direction ensures that the splitting path evenly covers the width and height of the curtain wall, avoiding excessively dense or sparse local cuts. The center position of the curtain wall is found in the front view, which can be determined by calculating the centroid. Starting from this point, an irregular splitting path parallel to the second splitting direction (diagonal line from the bottom left to the top right) is generated, and the components are designed accordingly to obtain multiple second splitting units.

[0109] S3, when the initial splitting parameters do not meet the scenario parameters, the rule combination mechanism is triggered to combine multiple splitting paths to obtain a combined path.

[0110] Construction scenarios are often highly complex, with numerous constraints and uncertainties. In practice, the initially generated splitting parameters may not fully meet all scenario requirements. For example, while the width of the initially split component units might meet the transportation path requirements, their height might exceed the maximum lifting height of the hoisting equipment. In such cases, a rule combination mechanism can be triggered to generate a splitting scheme that comprehensively meets the actual needs of the complex scenario by reasonably combining and adjusting multiple splitting paths. This ensures that after splitting, each unit can smoothly pass through transportation, hoisting, and other construction stages in terms of size and shape, reducing construction delays and safety accidents caused by unreasonable schemes.

[0111] The rule combination mechanism is a set of rules with intelligent decision-making capabilities, containing various strategies for solving splitting problems in complex scenarios. When the initial splitting parameters of a component do not meet the scenario parameters, differentiated combination strategies can be used to ensure the safety and compliance of load-bearing components and the flexible adaptation of non-load-bearing components.

[0112] A composite path is the final splitting path organically superimposed from multiple different splitting paths according to a rule-based combination mechanism. It can be determined after comprehensive analysis and optimization based on specific component characteristics, scenario parameters, and various constraints. For example, for a large, structurally complex load-bearing component, a rule-based path might be used for the initial splitting, dividing it into several larger units. However, when checking whether these units meet the size requirements of the hoisting equipment, it is found that their height still exceeds the limit. At this point, a rule-based combination mechanism can be used to superimpose these paths, resulting in multiple smaller units that meet the size requirements of the hoisting equipment.

[0113] Based on the above embodiments, step S3 can be implemented in the following ways:

[0114] S31, when the initial splitting parameters of the component to be split of the load-bearing attribute do not meet the specification parameters corresponding to the scenario parameters, obtain the user-defined auto-defined path, and superimpose the auto-defined path and the rule splitting path to obtain the first combined path.

[0115] The disassembly of load-bearing components must strictly adhere to structural safety principles. While rule-based disassembly paths can guarantee basic safety, in complex scenarios (such as special transport channel shapes or irregularly shaped load-bearing structures), the initial parameters may not meet the scenario's limitations. In such cases, users can manually define custom paths and supplement and optimize the rule-based paths according to actual needs. Overlaying the custom paths with the rule-based paths forms the first combined path, which retains the safety constraints of the rule-based paths while flexibly adapting to special scenarios.

[0116] The custom path is a split line manually drawn by the user according to the actual needs of the scenario, and must be within the range allowed by the system safety rules (e.g., distance from the main reinforcement ≥ 200mm). The first combined path is the final splitting scheme after merging the custom path and the rule-based splitting path.

[0117] Suppose an 8m long concrete load-bearing beam needs to be demolished, but the transport channel has irregular bends, requiring the length of each segmented unit to not exceed 2.5m. The initial segmentation parameters generated by the template are 3m vertical segments, resulting in 3 units (3m + 3m + 2m), which does not meet the length limit. The user manually draws two additional horizontal segmentation lines in the beam's top view, further dividing the 3m units into 2m + 1m segments. The system overlays the user's path with the original vertical segmentation lines, forming a first combined path of "vertical segmentation + horizontal cutting," ultimately resulting in 5 units with a length ≤ 2.5m, with all segmentation lines avoiding the main reinforcement area.

[0118] S32, when the initial splitting parameters of the component to be split without load-bearing attributes do not meet the specification parameters corresponding to the scene parameters, a supplementary path is generated according to the irregular splitting path, and the irregular splitting path and the supplementary path are superimposed to obtain a second combined path.

[0119] The combined path includes a first combined path and a second combined path, and the split path further includes an automatically defined path and a supplementary path.

[0120] Non-load-bearing components offer high flexibility in disassembly, but the initial irregular paths may not fully meet requirements due to the complex shape of the components or scene limitations (such as the turning radius in narrow alleys). Generating supplementary paths and overlaying them can dynamically optimize the disassembly scheme, further refining the unit shape and size by utilizing the degree of freedom of the irregular paths, ensuring that the disassembled components can smoothly pass through the transportation and installation stages.

[0121] The supplementary path is an auxiliary splitting line automatically generated based on scene constraints and the effect of the initial path. The second combined path is the final splitting scheme after merging the irregular splitting path with the supplementary path.

[0122] In some embodiments, the supplementary path can be generated through the following steps:

[0123] Using the farthest component outline point in the second view corresponding to the non-load-bearing component to be split as a reference, a baseline parallel to the second splitting direction is generated, and a supplementary path is generated based on the baseline and the centerline direction of the second splitting direction.

[0124] Generating a baseline using the farthest outline point in the view as a reference allows for quick location of the component's maximum span direction, ensuring that subsequent splitting paths cover the entire component. Generating a baseline parallel to the second splitting direction provides a unified reference axis for supplementary paths based on the determined splitting direction, resulting in a more even and reasonable distribution of splitting paths and avoiding areas that are too dense or too sparse.

[0125] By combining the baseline and the centerline direction to generate supplementary paths, the baseline determines the approximate direction and interval of the splitting, while the supplementary paths generated by combining the centerline direction of the second splitting direction can further refine the splitting scheme and optimize the element shape and size. The centerline direction can balance the splitting areas on both sides of the baseline, avoiding elements on one side being too large or too small.

[0126] S4. Generate combination and split parameters according to the combination path and send them to the execution device to drive the execution device to perform split operation, and obtain delivery data by associating the physical components and digital models of the component to be split.

[0127] Once the optimal combination path is determined, it can be translated into specific operational instructions so that the executing equipment can accurately perform the disassembly operation. The generated combination and disassembly parameters contain various detailed information required by the executing equipment, such as cutting position, cutting depth, cutting speed, and crushing force. Simultaneously, linking the disassembly operation to a digital model and acquiring delivery data enables digital management and full-process traceability of the entire disassembly process. This not only helps improve the controllability and transparency of the construction process but also facilitates subsequent quality inspections, maintenance, and overall project management. Through the digital model and delivery data, construction personnel can clearly understand the disassembly process, status, and related information of each component, promptly identify and resolve potential problems, and ensure the smooth delivery of the project.

[0128] Execution equipment refers to devices used to actually perform component disassembly operations. It possesses high-precision operating capabilities and good stability, enabling accurate cutting, crushing, and handling operations according to preset combination and disassembly parameters. Common execution equipment includes five-axis cutting machines, which can move along five different axes, achieving complex shape cutting tasks and suitable for building components of various materials. Industrial robots are also commonly used execution equipment; they can be programmed for precise positioning and operation, using robotic arms and other devices to grasp, move, and disassemble components, exhibiting high flexibility and adaptability.

[0129] Delivery data refers to a collection of data related to physical components and digital models generated throughout the disassembly process. It includes entity unit numbers, unique identifiers assigned to each disassembled entity component according to specific rules, such as "project code - component type - disassembly order," which allows for accurate identification and tracking of each component; disassembly trajectories recording the specific operational paths and sequences of components during disassembly, crucial for quality inspection and troubleshooting; and installation instructions, recorded in detailed text descriptions, images, or 3D animations, providing construction personnel with key information such as the installation sequence, connection methods, and installation locations of disassembled component units, ensuring correct and error-free installation. This delivery data can be tightly linked to physical components using technologies such as RFID (Radio Frequency Identification) tags, enabling each physical component to carry its associated digital information, achieving seamless integration between the physical and digital worlds.

[0130] For example, in a real construction project, for an L-shaped concrete load-bearing wall panel with a predetermined assembly path, the system will accurately calculate and generate cutting parameters for a five-axis cutting machine based on the assembly path. These parameters include detailed information such as the starting position of the cutting tool, its movement trajectory in different axes, cutting depth, and cutting speed. Then, these assembly / disassembly parameters are sent to the five-axis cutting machine, which, according to the received instructions, begins a precise cutting operation on the L-shaped concrete load-bearing wall panel. Each disassembled unit has an RFID tag embedded on its surface, storing the delivery data corresponding to that unit.

[0131] By using a method that generates combined splitting parameters based on combined paths and drives the execution device to perform operations, the splitting accuracy, quality, and precision can be improved.

[0134] The matching module is used to match a splitting template based on the component features of the component to be split, and generate initial splitting parameters for the component to be split according to the splitting path of the splitting template.

[0136] The association module is used to generate combination and splitting parameters based on the combination path and send them to the execution device to drive the execution device to perform splitting operations, and associate the physical components and digital models of the components to be split to obtain delivery data.
