Description

Technical Field

[0001] This application relates to the field of building curtain wall construction technology, and in particular to a curtain wall construction management method, system and equipment. Background Technology

[0002] Currently, in curtain wall construction, construction plans largely rely on the experience of construction personnel, lacking standardized and intelligent planning methods. This is especially true in the planning of construction paths and the installation of embedded parts. The lack of pre-construction analysis of the construction path and embedded part installation leads to interference between construction equipment (such as hoisting equipment and scaffolding), the work paths of construction personnel, and the installation positions and structural dimensions of embedded parts. This necessitates temporary adjustments to the construction plan or dismantling and rework, severely impacting construction progress and increasing costs. Therefore, to address the shortcomings of existing technologies, a curtain wall construction management method is urgently needed. This method should enable intelligent generation of plans and quantitative interference assessment before construction, resolving the issues of inaccurate interference hazard identification and unreasonable construction plans in existing technologies, thereby improving the intelligence and standardization of curtain wall construction management. Summary of the Invention

[0003] The main purpose of this application is to provide a curtain wall construction management method, system and equipment, which aims to solve the technical problem that the existing curtain wall construction methods are not accurate in identifying construction interference risks, resulting in unreasonable construction plans.

[0004] To achieve the above objectives, this application provides a curtain wall construction management method, comprising the following steps: Obtain basic parameters for curtain wall construction to determine construction milestones; Based on the construction nodes, an initial construction plan is generated; the initial construction plan includes construction path information, construction equipment information, and embedded part attribute parameters. Based on the construction path information, construction equipment information, and embedded part attribute parameters, determine whether there are any interference situations. Among them, interference situations include interference between the construction path and the embedded parts, interference between embedded parts, interference between construction equipment and embedded parts, compatibility interference between embedded part materials and construction equipment, and safety interference between embedded part hoisting and environmental wind resistance. If interference exists, the initial construction plan is adjusted to obtain an optimized construction plan, and then the process is repeated until the optimized construction plan is free from any interference, based on the construction path information, construction equipment information, and embedded part attribute parameters.

[0005] Optionally, methods for determining interference between the construction path and the embedded parts include: To obtain the three-dimensional spatial distance d between any point P(x, y, z) on the construction path and the installation center coordinates Q(x0, y0, z0) of a nearby embedded part, the expression for d is:

[0006] If d < k, where k is a preset safety threshold, it is determined that there is interference between the construction path and the corresponding embedded part; if d ≥ k, it is determined that there is no interference between the construction path and the corresponding embedded part.

[0007] Optionally, the method for judging interference between embedded parts includes: Obtain the center distance s between any two adjacent embedded parts Q1(x1, y1, z1) and Q2(x2, y2, z2). The expression for s is:

[0008] Obtain the sum S of the maximum outer dimensions of two adjacent embedded parts max , S max The expression for is: S max = max(a1, b1, c1) + (a2, b2, c2) + 2Δ In the formula, a1, b1, and c1 are the length, width, and thickness of the first embedded part respectively, a2, b2, and c2 are the length, width, and thickness of the second embedded part respectively, and Δ is the installation error threshold of the embedded part; If s < S max , it is determined that there is installation interference between two adjacent embedded parts; if s ≥ S max , it is determined that there is no interference between two adjacent embedded parts.

[0009] Optionally, the method for judging interference between the construction equipment and the embedded part includes: Set the working area of the construction equipment as a hemisphere with a radius of R; Obtain the minimum distance d between the center coordinates E(x e , y e , z e ) of the construction equipment and the installation center coordinates Q(x0, y0, z0) of the embedded part e , d e The expression for is:

[0011] Optionally, the method for judging compatibility interference between the embedded part material and the construction equipment includes: The additional stress σ exerted on the embedded parts by the construction equipment along the construction path is obtained. The expression for σ is: σ=F·L / I·W In the formula, F is the additional force exerted by the construction equipment on the embedded part, L is the lever arm of the force exerted by the construction equipment on the embedded part, I is the moment of inertia of the embedded part, and W is the section modulus of the embedded part. If σ > min(σ1, σ2), where σ1 is the tensile strength of the embedded part and σ2 is the compressive strength of the embedded part, then it is determined that there is compatibility interference between the embedded part material and the construction equipment; if σ ≤ min(σ1, σ2), then it is determined that there is no interference between the embedded part material and the construction equipment.

[0012] Optionally, methods for determining safety interference between the hoisting of embedded parts and environmental wind resistance include: Obtain the horizontal wind force F generated by the embedded parts to be hoisted, which is the environmental wind resistance. w F w The expression is: F w =C·ρ·S·v 2 / 2 In the formula, C is the wind resistance coefficient, which is determined according to the shape and structure of the embedded part, ρ is the air density, S is the windward area of ​​the embedded part, and v is the instantaneous wind speed in the construction environment. Obtain the maximum allowable swing amplitude A during the hoisting process of the embedded part. max A max The expression is:

[0013] In the formula, h is the hoisting height, which is the vertical height of the embedded part from the ground or the installed structure during the hoisting process, and k is the preset safety threshold. The actual swing amplitude A of the embedded part is obtained, and the expression for A is: A=F w ·L / m·g; In the formula, L is the length of the hoisting rope, m is the mass of the embedded part, and g is the acceleration due to gravity; If A>A max If A ≤ A, then it is determined that there is a safety interference between the hoisting of the embedded parts and the environmental wind resistance; max But F w If the concentration is ≥0.3mg, a potential safety interference is considered; if A ≤ A max And F w If the concentration is less than 0.3 mg, it is determined that there is no safety interference.

[0014] Optionally, if at least two interference scenarios exist, the following steps are also included: For each interference scenario, obtain the interference severity rate U, adjustment cost rate M, adjustment time rate T, and the probability P of new interference occurring after adjustment. Input the interference rate value U, the adjustment cost rate value M, the adjustment time rate value T, and the probability value P of new interference after adjustment into the preset adjustment cost model to obtain the adjustment priority D corresponding to various interference situations. Prioritize adjusting the interference cases with the highest adjustment priority D, and then return to the previous step of obtaining the interference degree rate value U, adjustment cost rate value M, adjustment time rate value T, and probability value P of new interference after adjustment for each interference case, until the interference is eliminated.

[0015] Optionally, the expression for the adjusted cost model is: D=W1·U-W2·M-W3·T-W4·P In the formula, U = (threshold - actual difference) / threshold, M = corresponding intervention adjustment cost / maximum value of all intervention adjustment costs, T = corresponding intervention adjustment time / maximum value of all intervention adjustment times, W1 is the first weight coefficient, W2 is the second weight coefficient, W3 is the third weight coefficient, and W4 is the fourth weight coefficient.

[0016] To achieve the above objectives, this application also provides a curtain wall construction management system, comprising: The parameter acquisition module is used to acquire basic parameters for curtain wall construction in order to determine construction milestones; The scheme generation module is used to generate an initial construction scheme based on the construction nodes; the initial construction scheme includes construction path information, construction equipment information, and embedded part attribute parameters. The interference judgment module is used to determine whether there is any interference based on the construction path information, construction equipment information, and embedded part attribute parameters. Interference includes interference between the construction path and the embedded part, interference between embedded parts, interference between construction equipment and embedded parts, compatibility interference between embedded part materials and construction equipment, and safety interference between embedded part hoisting and environmental wind resistance. The scheme optimization module is used to adjust the initial construction scheme if there is any interference, so as to obtain an optimized construction scheme and return to the previous step of determining whether there is any interference based on the construction path information, construction equipment information and embedded part attribute parameters, until the optimized construction scheme has no interference.

[0017] To achieve the above objectives, this application also provides a computer device, which includes a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the above-described method.

[0018] To achieve the above objectives, this application also provides a computer-readable storage medium storing a computer program, on which a processor executes the computer program to implement the above-described method.

[0019] The beneficial effects that this application can achieve are as follows: After determining the construction nodes through the basic parameters of curtain wall construction, this application can generate an initial construction plan. This initial construction plan includes key information affecting interference, such as construction path information, construction equipment information, and embedded part attribute parameters. Based on the relationship between key information, it can determine whether there is any interference. The interference situation simultaneously considers multiple key interference risks, such as interference between the construction path and embedded parts, interference between embedded parts, interference between construction equipment and embedded parts, compatibility interference between embedded part materials and construction equipment, and safety interference between embedded part hoisting and environmental wind resistance. Various interference risks can be fully investigated. When interference is found, the initial construction plan can be adjusted to obtain an optimized construction plan, and interference can be investigated again until the optimized construction plan has no interference. Then the final construction plan can be output. Therefore, this application combines key information affecting interference to investigate multiple interference risks before curtain wall construction, which improves the rationality of the final construction plan, thereby improving the construction progress and reducing the construction cost.

[0025] Example 1 Reference Figure 1 This embodiment provides a curtain wall construction management method, including the following steps: Step S10: Obtain basic parameters for curtain wall construction to determine construction milestones; In this step, basic parameters for curtain wall construction can be obtained through a data acquisition module, including but not limited to: dimensions of the curtain wall construction area (length, height, thickness), coordinates of obstacles within the construction area (such as the location of building walls, beams, and columns), construction equipment parameters (operating radius of hoisting equipment, width of scaffolding), and installation density of embedded parts. Based on the total construction period and construction procedures (installation of embedded parts → installation of keel → installation of panels), construction nodes are divided, with each construction node corresponding to the completion time of a single construction procedure. The start and end times, construction scope, and quality standards of each node are clearly defined. For example, construction node 1: positioning and installation of embedded parts (start and end times T1-T2), the construction scope is the bottom layer area of ​​the curtain wall, and the quality standard is that the installation deviation of embedded parts is ≤5mm.

[0026] Step S20: Generate an initial construction plan based on the construction nodes; wherein, the initial construction plan includes construction path information, construction equipment information and embedded part attribute parameters; In this step, the three most core elements in the initial construction plan are the construction path information, construction equipment information, and the attribute parameters of embedded parts. The construction equipment can be determined according to the construction nodes. When planning the construction path, with the construction scope of the construction nodes as the boundary, combining the construction equipment information and the obstacle coordinates, plan the operation paths of construction personnel and construction equipment, and adopt the principle of "shortest path + obstacle-free avoidance" to generate the coordinate set P(x, y, z, t) of the construction path, where x, y, and z are the three-dimensional coordinates of a certain point on the path, and t is the time to pass through this point (matched with the start and end times of the construction nodes); when determining the attribute parameters of the embedded parts, the core attributes of the embedded parts in each construction node can be determined according to the curtain wall design requirements and the quality standards of the construction nodes. The attributes of the embedded parts include material parameters, structural dimension parameters, and installation coordinate parameters, which are specifically as follows: Material parameters: The material density μ of the embedded part (unit: kg / m 3 ), tensile strength σ1 (unit: MPa), and compressive strength σ2 (unit: MPa); Structural dimension parameters: The length a (unit: mm), width b (unit: mm), thickness c (unit: mm), and hole diameter d (unit: mm, if any) of the embedded part; Installation coordinate parameters: The three-dimensional installation coordinates Q(x0, y0, z0) of each embedded part, where x0, y0, and z0 are the three-dimensional coordinates of the center of the embedded part, and are in the same coordinate system as the coordinate set P(x, y, z, t) of the construction path.

[0027] Step S30: According to the construction path information, construction equipment information, and the attribute parameters of the embedded parts, judge whether there is an interference situation; among them, the interference situation includes interference between the construction path and the embedded parts, interference between the embedded parts, interference between the construction equipment and the embedded parts, compatibility interference between the material of the embedded part and the construction equipment, and safety interference between the hoisting of the embedded part and the environmental wind resistance; In this step, the judgment methods for each interference situation are as follows: As an optional implementation method, the judgment method for interference between the construction path and the embedded parts includes: Obtain the three-dimensional space distance d between any point P(x, y, z) on the construction path and the installation center coordinates Q(x0, y0, z0) of the nearby embedded part. The expression of d is:

[0028] If d < k, where k is a preset safety threshold, it is determined that there is interference between the construction path and the corresponding embedded part; if d ≥ k, it is determined that there is no interference between the construction path and the corresponding embedded part.

[0029] In this embodiment, during curtain wall construction, the interference between the construction path (personnel, equipment) and the embedded parts is essentially due to the fact that the spatial distance between the two is too close (less than the safety threshold k), resulting in collisions and obstructed operations. The algorithm calculates the straight-line distance d between two points through three-dimensional coordinates, converts the abstract "spatial position relationship" into specific values, and compares with the safety threshold k. If d < k, it indicates that the path and the embedded parts are spatially overlapped or too close, resulting in interference; if d ≥ k, it indicates that the two do not affect each other and there is no interference. Here, the value of k is determined according to the construction equipment size and the embedded part structure size, generally taking k = 20 - 50 mm (which can be adjusted according to the actual construction scenario). For example, when k = 30 mm, taking the construction path coordinate P(5, 0.4, 5) and the installation center coordinate Q(4, 0.4, 2) of the embedded part, substituting into the formula to calculate d:

[0030] Therefore, d = 3160 mm ≥ k = 30 mm, it can be determined that there is no interference. If it is determined that there is interference here, the construction path coordinates can be adjusted, or the installation coordinates of the embedded part can be slightly adjusted (adjustment amount ≤ Δ).

[0031] As an optional implementation, the method for determining interference between embedded parts includes: Obtain the center distance s between any two adjacent embedded parts Q1(x1, y1, z1) and Q2(x2, y2, z2). The expression of s is:

[0032] Obtain the sum S of the maximum outer dimensions of two adjacent embedded parts max , S max The expression of is: S max = max(a1, b1, c1) + (a2, b2, c2) + 2Δ In the formula, a1, b1, c1 are the length, width, and thickness of the first embedded part respectively, a2, b2, c2 are the length, width, and thickness of the second embedded part respectively, and Δ is the installation error threshold of the embedded part; If s < S max , it is determined that there is installation interference between the two adjacent embedded parts; if s ≥ S max , it is determined that there is no interference between the two adjacent embedded parts.

[0033] In this embodiment, due to the interference risk between adjacent embedded parts, which stems from "too close center distance" and "the outer dimensions exceed the center distance after superposition", and there are inevitable deviations Δ during the installation process, error redundancy needs to be reserved. Therefore, the center distance s (spatial distance between two points) of adjacent embedded parts is calculated simultaneously to reflect their basic spacing; the sum S of the maximum outer dimensions is calculated simultaneouslymax (Take the maximum value among the length, width, and thickness of each embedded part, add 2 times the installation error Δ after superposition), which reflects the "allowable minimum center distance" (including the redundancy of installation deviation); the judgment logic is: if s < S max , it means that even considering the installation deviation, the outer shapes of adjacent embedded parts will overlap, resulting in installation interference; if s ≥ S max , it means that the distance is sufficient to avoid collision. For example, first set the installation error threshold Δ (unit: mm) of the embedded part, that is, the maximum allowable deviation between the actual installation coordinates and the design coordinates of the embedded part. Let Δ ≤ 5mm. Take adjacent embedded parts Q1(2, 0.4, 2) and Q2(3, 0.4, 2), and calculate s:

[0034] The structural dimensions of two embedded parts are known as follows: the first embedded part: a1 = 500mm, b1 = 50mm, c1 = 20mm; the second embedded part: a2 = 600mm, b2 = 60mm, c2 = 20mm. Therefore, S can be calculated max = 500 + 600 + 2×5 = 1110mm, s = 1000mm < 1110mm, then it is determined that there is installation interference between two adjacent embedded parts. At this time, the installation density of the embedded parts can be adjusted, or the structural dimensions of the embedded parts can be optimized (within the allowable range of design).

[0035] As an optional implementation method, the method for judging interference between construction equipment and embedded parts includes: Set the working area of the construction equipment as a hemisphere with a radius of R; Obtain the minimum distance d e , y e , z e ) between the center coordinates E(x e , d e The expression of is:

[0036] If d e < k, k is a preset safety threshold, then it is determined that there is interference between the construction equipment and the embedded part; if d e ≥ k, then it is determined that there is no interference between the construction equipment and the embedded part.

[0037] In this implementation method, since the operation of the construction equipment (such as a lifting equipment) has a fixed range (a hemisphere with the center of the equipment as the center of the sphere and the operation radius R as the radius), if the embedded part enters this area, it will collide with the equipment. Therefore, here, by calculating the spatial distance (distance between two points) between the center of the equipment and the center of the embedded part, and then subtracting the operation radius R of the equipment, the minimum distance d is obtainede (If d e is negative, it means that the embedded part has entered the equipment operation area and there is interference); therefore, the judgment logic is: d e < k (safety threshold), which means that the equipment will collide with the embedded part during operation (even if it has not completely entered the operation area, there is still a risk if the distance is too close); d e ≥ k, which means that there is no overlap and no interference between the equipment operation area and the embedded part. It has been determined that k = 30 mm before. Here, taking the lifting equipment as an example of the construction equipment, it is known that the operation radius R of the lifting equipment is 8 m, and the initial center coordinates of the lifting equipment are E(10, 0.4, 5). It has been known that the installation center coordinates of the embedded part are Q(4, 0.4, 2), then it can be calculated that m = -1300 mm < 30 mm, then it can be determined that there is interference between the construction equipment and the embedded part; when there is such interference, it can be adjusted by replacing the construction equipment (adjusting the operation radius R) or planning the equipment avoidance path.

[0038] As an optional implementation manner, the method for judging the adaptability interference between the material of the embedded part and the construction equipment includes: Obtain the additional stress σ generated by the construction equipment on the embedded part on the construction path. The expression of σ is: σ = F·L / I·W In the formula, F is the additional force of the construction equipment on the embedded part, L is the force arm of the force of the construction equipment on the embedded part, I is the sectional moment of inertia of the embedded part, and W is the sectional resistance moment of the embedded part; If σ > min(σ1, σ2), where σ1 is the tensile strength of the embedded part and σ2 is the compressive strength of the embedded part, it is determined that there is adaptability interference between the material of the embedded part and the construction equipment; if σ ≤ min(σ1, σ2), it is determined that there is no interference between the material of the embedded part and the construction equipment.

[0039] In this implementation manner, since such interference is "hidden interference", the equipment on the construction path will generate an additional force F on the embedded part. If the additional stress σ generated by this force exceeds the tensile strength σ1 or the compressive strength σ2 of the embedded part material, it will cause the embedded part to deform, and then lead to subsequent installation deviation (such as position offset), indirectly generating interference. The core logic of the above stress formula σ = F·L / I·W is: the additional stress is proportional to the additional force F and the force arm L, and inversely proportional to the sectional moment of inertia I and the sectional resistance moment W of the embedded part (I and W are determined by the structural dimensions of the embedded part and reflect the anti-deformation ability of the component); therefore, the judgment logic is: σ > min(σ1, σ2), which means that the material strength is insufficient and it is easy to deform and cause indirect interference; otherwise, the material is adaptable and there is no risk of hidden interference. It should be noted that the value of F is based on the weight and operation force of the construction equipment, and the calculations of I and W are based on the sectional dimensions of the embedded part (such as the moment of inertia formula I = b of the rectangular section c 3 / 12), the core of the algorithm is "avoiding the chain interference caused by material deformation in advance".

[0040] For example, the width and thickness of a certain embedded part are b=20mm and c=10mm respectively. Given that the additional force exerted by the construction equipment on the embedded part is F=5000N, the lever arm is L=500mm, and the moment of inertia of the embedded part's cross-section is I= (b×c) / (b×c) / (b×c) / (c ... 3 ) / 12=(20×10 3 ) / 12≈1667mm 4 Section modulus W = (b × c) 2 ) / 6=(20×10 2 ) / 6≈333mm 3 Substituting into the formula, we can calculate σ = 5000·500 / (1667·333) ≈ 4.5 MPa < min(235,205) = 205 MPa. Therefore, it can be determined that the materials are compatible and there is no indirect interference. If interference exists, adjustments can be made by replacing the embedded part material (to increase tensile / compressive strength) or optimizing the construction path to reduce the additional force F.

[0041] As an optional implementation method, the method for determining the safety interference between the hoisting of embedded parts and environmental wind resistance includes: Obtain the horizontal wind force F generated by the embedded parts to be hoisted, which is the environmental wind resistance. w F w The expression is: F w =C·ρ·S·v 2 / 2 In the formula, C is the wind resistance coefficient, which is determined according to the shape and structure of the embedded part, ρ is the air density, S is the windward area of ​​the embedded part, and v is the instantaneous wind speed in the construction environment. Obtain the maximum allowable swing amplitude A during the hoisting process of the embedded part. max A max The expression is:

[0042] In the formula, h is the hoisting height, which is the vertical height of the embedded part from the ground or the installed structure during the hoisting process, and k is the preset safety threshold. The actual swing amplitude A of the embedded part is obtained, and the expression for A is: A=F w ·L / m·g; In the formula, L is the length of the hoisting rope, m is the mass of the embedded part, and g is the acceleration due to gravity; If A>A max If A ≤ A, then it is determined that there is a safety interference between the hoisting of the embedded parts and the environmental wind resistance;max But F w If the wind resistance force is ≥0.3mg (i.e., the wind resistance force reaches 30% of the weight of the embedded part), then a potential safety interference is determined; if A ≤ A max And F w If the concentration is less than 0.3 mg, it is determined that there is no safety interference.

[0043] In this embodiment, during the hoisting process, environmental wind resistance will generate a horizontal force on the embedded parts, i.e., horizontal wind force F. w This causes the embedded parts to swing around the suspension point of the hoisting ropes. If the swing amplitude is too large, it may collide (interfere) with equipment or obstacles, posing a hoisting safety hazard. Therefore, this assessment considers both "wind resistance" and "swing amplitude." The horizontal wind force F is calculated. w At that time, using the fluid dynamics wind resistance formula, wind resistance is related to the wind resistance coefficient C (determined by the shape of the embedded part) and the air density ρ (taken as 1.225 kg / m³ under standard working conditions). 3 (Can be corrected according to construction environment temperature and air pressure), windward area S (windward projected area of ​​embedded part), wind speed square v 2 (v can be collected in real time by a wind speed sensor) is directly proportional, and the core is to quantify the magnitude of the force exerted by the wind on the embedded parts; then calculate the maximum allowable sway amplitude A. max (Geometric Relationship): Combining the hoisting height h and the safety threshold k (consistent with the previous text, taken as 30mm), the Pythagorean theorem can be used to derive the "maximum sway limit to avoid collision" (the higher the hoisting height, the smaller the allowable sway amplitude); then calculate the actual sway amplitude A (mechanical equilibrium): the sway amplitude is related to the horizontal wind force F. w The rope length L is directly proportional to the mass m of the embedded part and the gravitational acceleration g (taken as 9.8 m / s²). 2 The risk is inversely proportional to (i.e., the mechanical derivation under equilibrium conditions), reflecting the actual sway caused by wind resistance; therefore, the judgment logic here can be divided into two categories of risk: A>A max (Direct collision and interference pose a high safety hazard); A≤A max But F w ≥0.3mg (potential risk exists; sudden changes in wind speed can easily cause increased swaying, leading to indirect interference); if neither of these conditions is met, there is no interference condition. It should be noted that the drag coefficient C is determined based on the shape of the embedded part (1.2-1.5 for flat types, 1.5-2.0 for irregular shapes), stemming from the fluid mechanics concept of "differences in drag coefficients for different shapes"; the calculation of the windward area S (a×c for flat types) is based on the actual windward surface of the embedded part during hoisting. The core algorithm is to "convert the dynamic influence of wind resistance into quantitative parameters," avoiding dynamic interference during hoisting.

[0044] For example, the relevant parameters for hoisting wind resistance interference can be determined as follows: embedded part length a = 0.3m, thickness c = 0.02m, hoisting height h = 10m, wind resistance coefficient C = 1.3 (for flat embedded parts), and air density ρ = 1.225kg / m³. 3 The windward area of ​​the embedded part is S = 0.3m × 0.02m = 0.006m², the length of the hoisting rope is L = 12m, and the mass of the embedded part is m = 9.42kg; the real-time wind speed in the construction environment is v = 2.5m / s. Substituting these values ​​into the formula, we can obtain the following: (1) Horizontal wind force F w :F w =1.3 × 1.225 × 0.006 × 2.5 2 / 2≈0.03N (2) Maximum permissible swing amplitude A max : ; (3) Actual swing amplitude A: ; (4) Judgment result: A=3.9mm>A max =0.045mm, and F w =0.030N < 0.3 × 9.42 × 9.8 ≈ 27.7N, which is considered a serious interference with the safety of hoisting due to wind resistance. Hoisting must be stopped immediately, and the wind speed must be allowed to decrease to v ≤ 3m / s (here v = 2.5m / s meets the requirement, but the actual deviation is due to the calculation example). The hoisting rope length is adjusted to L = 15m, and A = 0.0031m = 3.1mm is recalculated. It still exceeds A. max Ultimately, windproof cables were installed to control A within 0.04mm to eliminate interference. If it is a potential safety interference, it can be adjusted by reducing the hoisting speed, increasing the tension of the hoisting ropes, arranging personnel to monitor on-site, monitoring wind speed changes in real time, or adjusting the hoisting time to avoid periods of strong wind.

[0045] In summary, the core logic of the aforementioned interference judgment algorithms is unified as "abstract scenario → geometric / mechanical modeling → quantitative calculation → threshold comparison," comprehensively considering the impact of direct and indirect interference. Direct interference (path-embedded parts, adjacent embedded parts, equipment-embedded parts) focuses on "spatial position / size matching," quantifying distance and size based on geometric principles and comparing safety thresholds. Indirect interference (material adaptation, hoisting wind resistance) focuses on "hidden risks (deformation, swaying)," quantifying stress and sway amplitude based on mechanical / fluid dynamics principles and comparing material strength and safe sway limits. Furthermore, all parameters are derived from actual curtain wall construction scenarios (quality standards, equipment parameters, environmental conditions), ensuring the practicality and operability of the algorithms.

[0046] Step S40: If interference exists, the initial construction plan is adjusted to obtain an optimized construction plan, and the process returns to the step of determining whether interference exists based on the construction path information, construction equipment information, and embedded part attribute parameters, until the optimized construction plan is free from any interference.

[0047] In this step, adjusting the interference may trigger other interferences. Therefore, the construction path information, construction equipment information, and embedded part attribute parameters in the adjusted optimized construction plan are substituted into the above interference algorithms again to iterate the interference situation until none of the above interference situations exist, thus obtaining the optimized final construction plan.

[0048] It should be noted that, based on the final construction plan, during the curtain wall construction process, actual construction parameters (such as the actual installation coordinates of embedded parts and the actual walking trajectory of the construction path) can be collected in real time and substituted into the above interference judgment algorithms to dynamically verify whether there is interference. If the actual parameters deviate too much from the initial plan, the construction plan will be automatically updated to ensure that there is no interference throughout the entire construction process.

[0049] As an optional implementation, if at least two interference scenarios exist, the following steps are also included: For each interference scenario, obtain the interference severity rate U, adjustment cost rate M, adjustment time rate T, and the probability P of new interference occurring after adjustment. Input the interference rate value U, the adjustment cost rate value M, the adjustment time rate value T, and the probability value P of new interference after adjustment into the preset adjustment cost model to obtain the adjustment priority D corresponding to various interference situations. Prioritize adjusting the interference cases with the highest adjustment priority D, and then return to the previous step of obtaining the interference degree rate value U, adjustment cost rate value M, adjustment time rate value T, and probability value P of new interference after adjustment for each interference case, until the interference is eliminated.

[0050] In this implementation, when two or more interference situations are detected by the aforementioned interference judgment algorithm, in order to achieve the optimal adjustment effect and minimize the adjustment cost and schedule impact, the adjustment priority of each interference situation is evaluated. This facilitates prioritizing the adjustment of the interference situation with the highest priority, and then processing the remaining interferences in turn, avoiding blind adjustments that may cause new interferences or waste of resources. Here, the adjustment priority is defined as: comprehensively reflecting the necessity of adjusting a single interference situation. The greater the cost value, the more serious the impact of not adjusting the interference on construction, and the higher the benefits (reduced rework, shortened schedule, reduced costs) after adjustment. Therefore, when the adjustment priority D corresponding to each interference situation is calculated, the interference situation with the highest adjustment priority D is adjusted first. After adjustment, the adjustment priority is recalculated until all interference situations are resolved (no interference), or the adjustment priority of the remaining interference situations are all negative (at this time, the benefit of adjusting the interference is less than the cost, and alternative solutions such as temporary avoidance and local optimization can be adopted according to the actual construction situation). Therefore, the priority calculation here combines four core dimensions: interference rate value U, adjustment cost rate value M, adjustment time rate value T, and the probability value P of new interference after adjustment. This allows for a comprehensive and accurate quantitative calculation of adjustment priority, providing effective reference and guidance.

[0051] As an optional implementation, the expression for the adjustment cost model is: D=W1·U-W2·M-W3·T-W4·P In the formula, U = (threshold - actual difference) / threshold, M = corresponding intervention adjustment cost / maximum value of all intervention adjustment costs, T = corresponding intervention adjustment time / maximum value of all intervention adjustment times, W1 is the first weight coefficient, W2 is the second weight coefficient, W3 is the third weight coefficient, and W4 is the fourth weight coefficient.

[0052] In this embodiment, a weighted summation method is used to construct the quantitative algorithm formula for the adjustment cost model. All four core parameters in the formula are standardized (with a uniform value range of [0,1]) to eliminate the influence of dimensions. The overall formula logic of the adjustment cost model is as follows: the interference rate value U is weighted with positive values ​​because the more severe the interference (i.e., the larger U is), the higher the priority. The adjustment cost rate value M, adjustment time rate value T, and the probability value P of new interference after adjustment are weighted with negative values ​​because the higher the adjustment cost, the longer the time, and the greater the probability of triggering new interference, the lower the adjustment priority. The calculation logic for the interference rate value U is as follows: based on the threshold of the corresponding interference type, i.e., U = (threshold - actual difference) / threshold (calculated when the actual difference < threshold, i.e., interference exists; if the actual difference ≥ threshold, there is no interference, U = 0). For example, in the case of path-embedded part interference, k = 30mm, the actual difference at a certain interference point d = 10mm, and the interference amount U = (30-10) / 30 ≈ 0.67. The adjustment cost rate value M reflects the economic cost (including material cost, equipment cost, labor cost, etc.) required to resolve the interference. Its calculation logic is: M = corresponding interference adjustment cost / maximum value of all interference adjustment costs. The larger the value, the higher the adjustment cost (the higher the cost, the higher the adjustment priority needs to be determined in conjunction with other dimensions, not simply by prioritizing higher costs). The adjustment time rate value T reflects the construction period required to resolve the interference. Its calculation logic is: T = corresponding interference adjustment time / maximum value of all interference adjustment times. The larger the value, the longer the adjustment time. The probability value P of new interference after adjustment reflects the probability that adjusting this interference will trigger new interference (such as adjusting the coordinates of an embedded part, causing new interference with adjacent embedded parts or construction paths). Its calculation logic is: the initial probability is determined by fitting historical construction data or expert evaluation, and then corrected based on the current construction scenario. The larger the value, the higher the risk of new interference after adjustment. The weighting coefficients mentioned above can be set according to the core needs of curtain wall construction (prioritizing construction safety and efficiency while considering cost).

[0053] Example explanation: Suppose that four interference scenarios are detected before the construction of a curtain wall, with weighting coefficients of W1=0.4, W2=0.2, W3=0.2, and W4=0.2. The standardized parameters for each interference are as follows: Interference 1 (path-embedded part interference): U=0.7, M=0.3, T=0.2, P=0.1; Interference 2 (interference between embedded parts): U=0.5, M=0.5, T=0.4, P=0.2; Interference 3 (Equipment-Embedded Part Interference): U=0.6, M=0.4, T=0.3, P=0.15; Interference 4 (Lifting wind resistance safety interference): U=0.85, M=0.2, T=0.5, P=0.1; Calculate the adjustment cost V for each interference: Interference 1: D = 0.4 × 0.7 - 0.2 × 0.3 - 0.2 × 0.2 - 0.2 × 0.1 = 0.16; Interference 2: D = 0.4 × 0.5 - 0.2 × 0.5 - 0.2 × 0.4 - 0.2 × 0.2 = -0.02; Interference 3: D = 0.4 × 0.6 - 0.2 × 0.4 - 0.2 × 0.3 - 0.2 × 0.15 = 0.07; Interference 4: D = 0.4 × 0.85 - 0.2 × 0.2 - 0.2 × 0.5 - 0.2 × 0.1 = 0.18; The sorting results are: Interference 4 > Interference 1 > Interference 3 > Interference 2. Prioritize adjusting the hoisting wind resistance safety interference (interference 4). After adjustment, recalculate the cost of the remaining interferences and then adjust them in sequence.

[0054] In summary, this application has the following significant effects: 1. Intelligent and standardized construction plan generation: Eliminates reliance on the experience of construction personnel, automatically generates construction paths and embedded part attribute plans based on construction nodes and quantitative parameters, ensuring the rationality and standardization of construction plans and improving the efficiency of construction plan generation; 2. Accurately identify interference problems: By constructing 5 core quantitative interference algorithm formulas, interference risks are comprehensively assessed from five dimensions: construction path, embedded parts, construction equipment, material compatibility, and hoisting wind resistance. The accuracy of the assessment is higher than that of manual visual inspection, which can identify potential interference hazards in advance and avoid rework and project delays. 3. Reduce construction costs: Reduce costs such as rework, equipment adjustment, and material waste caused by interference, while improving construction efficiency and shortening the construction period, making it highly practical and worthy of promotion.
