Description

Technical Field

[0001] This invention relates to the field of process design automation technology, and in particular to an ALC board intelligent installation system based on digital industrial production process design. Background Technology

[0002] The field of process design automation technology encompasses the research and application of digital modeling, parametric design, and automated configuration of process flows in industrial production. Its core content lies in the systematic planning of industrial product production processes through computer-aided design methods, unifying the design, analysis, and optimization of each process step into a digital platform to achieve automatic generation and dynamic adjustment of process routes. Its overall system covers process modeling, virtual simulation, process parameter optimization, production scheduling design, and assembly process planning, emphasizing a data-driven approach to transform process design from experience-based decision-making to digital and intelligent decision-making, and improving the collaborative efficiency of design and manufacturing through linkage with production execution.

[0003] The ALC intelligent installation system for autoclaved lightweight concrete (ACC) panels, based on digital industrial production process design, utilizes digital process modeling, automated installation path planning, and intelligent construction auxiliary control to standardize and regulate the installation process of ACC panels in building construction. The technical aspects addressed include panel installation sequence planning, digital generation of construction paths, setting of positioning and assembly parameters, and real-time monitoring and adjustment of the installation process. Specifically, it achieves this through 3D process modeling to simulate the installation path and panel layout, automatically generating the installation sequence based on parametric rules to determine the construction order, and combining sensing and control methods to achieve positioning correction and dynamic adjustment during installation, thus forming a complete panel installation process design system.

[0004] While existing technologies have achieved digital modeling and parametric design of process flows, they lack dynamic response mechanisms for mechanical changes, installation errors, and actual construction feedback during execution. Path generation is mostly static planning, which is difficult to cope with node position deviations caused by fluctuations in stress conditions in the field environment. Joint control usually relies on fixed value settings and lacks automatic allocation capabilities based on field test results. Process arrangement relies on preset plans and lacks quantitative assessment and delay mitigation methods for real-time time changes. Although support bearing capacity monitoring data is collected, a difference recording and ratio classification mechanism has not been established, making it difficult to complete timely identification of abnormal nodes and structural linkage correction. Flatness detection has also not established refined offset analysis and cannot provide clear structural quality feedback. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and propose an ALC board intelligent installation system based on digital industrial production process design.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an ALC board intelligent installation system based on digital industrial production process design, the system comprising:

[0007] The path adjustment module collects and compares the tension value of the wire rope at the lifting point, the displacement of the ALC plate, and the bearing capacity value of the support point. It then compares the tension value with the rated lifting threshold point by point and judges the difference between the displacement and the bearing capacity value. If the difference exceeds the installation displacement threshold, it corrects the path node position and replaces the path segment, generating a plate installation path adjustment instruction.

[0008] The seam correction module calls the board installation path adjustment command and calculates the difference between the measured width of the seam clamp and the design reference width. When the difference is accumulated and close to the allowable range, it is distributed to the subsequent three boards for equal-ratio correction to obtain the seam correction positioning value.

[0009] The process connection module calls the seam correction and positioning value, calculates the difference between the actual time and the planned time of the process, and accumulates it to form a delay amount.

[0018] The cumulative amount recording submodule performs a summation operation on all path segments according to the seam width difference sequence, records the current cumulative value after each segment, calculates the difference between the cumulative value and the seam allowable range, extracts the cumulative value segment that is close to the allowable range, and obtains the seam cumulative close value interval.

[0019] The positioning value correction submodule calls the path segment position corresponding to the cumulative proximity value interval of the splice, allocates the cumulative value of the current segment to the positioning positions of the subsequent three boards, calculates the equally distributed single-board positioning offset value, and corrects the offset in the original positioning path to generate the board splice correction positioning value.

[0020] As a further embodiment of the present invention, the process connection module includes a time consumption difference calculation submodule, a delay amount generation submodule, and a time interval correction submodule;

[0021] The time difference calculation submodule calls the board joint correction positioning value and performs positioning matching on the process number, collects the actual time consumption record of the corresponding process and calls the planned time consumption record of the process, calculates the time difference between the two in each process, subtracts the planned time consumption from the actual time consumption to form a difference list, and generates a process time difference sequence.

[0022] The delay generation submodule sums up each difference sequentially according to the process time difference sequence, records the cumulative value at each process node position in the cumulative result, compares the process delay range with the cumulative value of each node, extracts the node index that exceeds the process delay range, and obtains the process cumulative delay segment.

[0023] The time interval correction submodule calls the list of subsequent processes corresponding to the cumulative delay segment of the process, proportionally distributes the time intervals of the three processes after the process node, calculates the time value to be deducted in each process and performs time interval adjustment, and establishes an installation process connection schedule.

[0024] As a further embodiment of the present invention, the node detection module includes a ratio extraction submodule, an interval judgment submodule, and an offset quantization submodule;

[0025] The ratio extraction submodule calls the installation process connection schedule, locates the process number of each support node, collects the bearing capacity test value of each node support point and calls the corresponding rated bearing capacity value, divides the bearing capacity test value of each support point by the rated bearing capacity value, arranges the ratio results according to the node order, and generates a support node bearing ratio sequence.

[0026] The interval judgment submodule calls the upper and lower limits of the allowable interval of bearing capacity item by item according to the bearing ratio sequence of the support nodes, judges whether each ratio exceeds the corresponding interval limit, records the node index position where the deviation occurs, extracts all deviation node numbers, and obtains the over-limit node index set.

[0027] The offset quantization submodule calls the over-limit node index set to locate the node index number, re-acquires the corresponding ratio for each node and performs difference processing with the boundary value of its interval, records the difference as the offset amplitude value according to the node number, and summarizes them into a unified record in sequence to generate a support node bearing difference record.

[0028] As a further aspect of the present invention, the system further includes:

[0029] The structural confirmation module calls the support node bearing difference record and calculates the difference by combining the flatness measurement value and control range after the plate installation is completed. It then compares the difference with the range, quantifies the offset into an interval difference and marks the range to obtain the installation structure confirmation result.

[0030] The confirmation results of the ALC plate installation structure include flatness difference, judgment results within the flatness control range, and offset quantification range.

[0031] As a further embodiment of the present invention, the structure confirmation module includes a measurement difference extraction submodule, an interval offset judgment submodule, and a structure deviation annotation submodule;

[0032] The measurement difference extraction submodule calls the bearing difference record of the support node, obtains the plate number of the corresponding support node and locates its plate range, collects the flatness measurement value after the ALC plate is installed and calls the design median value of the flatness control range, subtracts the design median value from the flatness measurement value and arranges them in the plate order to generate a plate flatness difference sequence.

[0033] The interval offset judgment submodule, based on the plate flatness difference value sequence, calls the upper and lower limits of the flatness control range, compares each item of the difference sequence with the upper and lower limits of the interval, extracts all plate numbers that deviate from the interval boundary, and obtains the flatness deviation plate index set.

[0034] The structural deviation annotation submodule calls the flatness difference value corresponding to each plate in the flatness deviation plate index set, divides the difference value range into multiple segments according to the preset interval, locates the interval segment to which each value belongs and records the interval identification, and combines the support node position number to perform annotation summary to generate ALC plate installation structure confirmation result.

[0035] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0036] In this invention, by jointly analyzing hoisting tension, displacement, and bearing capacity, and correcting node positions and replacing path segments, the system can dynamically adapt to changes in actual stress conditions, improving the accuracy and adjustability of path generation. A joint control mechanism based on dynamic offset allocation is constructed through segment-by-segment accumulation and real-time distribution of joint deviations, improving the consistency and tightness of panel joints. The accumulation of time difference forms a delay, which is then used to adjust subsequent time intervals, achieving dynamic coordination and time continuity control of the installation rhythm. Quantitative judgment of support ratios establishes a bearing difference record, facilitating precise identification and hierarchical management of support node states. Finally, matching analysis of offset and flatness interval differences enables quantifiable confirmation of structural effects, strengthening structural feedback and quality assurance upon completion of installation.

[0046] In this embodiment of the invention, sometimes a subscript such as W1 may be written in a non-subscript form such as W1. When the difference is not emphasized, the meaning they express is the same.

[0047] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0048] Please see Figure 1 This invention provides a technical solution: an ALC board intelligent installation system based on digital industrial production process design, the system comprising:

[0049] The path adjustment module collects and compares the tension value of the wire rope at the lifting point, the displacement of the ALC plate, and the bearing capacity value of the support point. It then compares the tension value with the rated lifting threshold point by point and judges the difference between the plate displacement and the bearing capacity value of the support point. If the difference exceeds the installation displacement threshold, it corrects the path node position and replaces the relevant path segment, generating a plate installation path adjustment instruction.

[0050] The seam correction module calls the board installation path adjustment command and calculates the difference between the measured width of the seam clamp and the design reference width. The difference is accumulated segment by segment and the cumulative value is recorded. The cumulative value is called and the seam allowable range is judged for closeness. When the cumulative value is close to the allowable range, it is allocated to the positioning of the subsequent three boards for equal distribution correction, and the board seam correction positioning value is obtained.

[0051] The process connection module calls the board joint correction positioning value and calculates the difference between the actual process time record and the planned process time record. The difference is accumulated segment by segment to form a delay amount. The delay amount is compared with the process delay range. When the delay amount exceeds the delay range, it is allocated to the subsequent process and its time interval is adjusted to obtain the installation process connection timetable.

[0052] The node detection module calls the installation process connection schedule and compares the support point bearing capacity detection value with the rated bearing capacity value. It then calls the ratio of the two and the allowable bearing capacity range to make a judgment. When the ratio deviates from the allowable bearing capacity range, it records the deviation magnitude and converts it into a quantitative value, generating a support node bearing capacity difference record.

[0053] The structural confirmation module calls the support node load difference record and calculates the difference by combining the flatness measurement value after the ALC plate installation is completed with the flatness control range. It then compares the difference with the flatness control range, quantifies the offset into interval difference, and marks the corresponding range to obtain the ALC plate installation structural confirmation result.

[0054] The panel installation path adjustment instructions include the tensile value threshold comparison results, the panel displacement and support point bearing capacity difference judgment results, path node correction positions and replacement path segments; panel joint correction positioning values ​​include joint width difference, cumulative difference, joint proximity judgment results within the allowable range, and positioning correction values ​​for the subsequent three panels; the installation process connection schedule includes process delay, process delay range and adjusted time interval; support node bearing capacity difference records include the support point bearing capacity test value and rated bearing capacity ratio, bearing capacity deviation and allowable range judgment results; ALC panel installation structure confirmation results include flatness difference, flatness control range judgment results, and offset quantification range.

[0055] Please see Figure 2 The path adjustment module includes a tension verification submodule, a displacement difference judgment submodule, and a path correction submodule;

[0056] The tension verification submodule collects the tension value of the wire rope at the lifting point and calls the rated lifting threshold to compare it point by point. It subtracts the rated lifting threshold from the tension value of the wire rope at each lifting point to form a corresponding difference sequence, and generates the lifting point tension difference sequence.

[0057] The system collects the tension values ​​of the wire rope at each lifting point and compares them against the rated lifting threshold. Tension sensors installed at four lifting points (C1, C2, C3, C4) on the lifting beam continuously collect real-time tension data at a frequency of 10Hz, forming a data stream. For example, at a specific sampling time t1, a set of instantaneous tension values ​​is collected as [2850N, 2865N, 2845N, 2860N]. The system then retrieves the preset rated lifting threshold T from memory. rated This threshold is based on standard ALC sheet (model specifications: length 6000mm, width 600mm, thickness 150mm, dry density 650kg / m³). 3 Based on the analysis of the physical properties of the material, the volume of the board is first calculated as V = 6.0m × 0.6m × 0.15m = 0.54m. 3 Next, its mass is calculated as m = V × 650 kg / m 3 =351kg, corresponding to a static load of G = m × 9.8m / s² 2 The static load is approximately 3439.8 N. Considering the dynamic load generated by lifting and braking operations, statistical analysis was conducted on experimental data from 500 complete lifting cycles. The peak tensile force under different accelerations was recorded. The data showed that 99.7% of the peak tensile forces did not exceed 1.3 times the static load. Therefore, the dynamic coefficient K was selected. dyn =1.3, and to meet the requirements of the "Safety Regulations for Lifting Machinery" (GB6067.1-2010), a safety factor S is introduced. f =2.5, and the final calculated rated lifting threshold for a single wire rope is T. rated = (G×K) dyn / 4)×S f = (3439.8N × 1.3 / 4) × 2.5 ≈ 2795N. The system will subtract the tension value of each lifting point collected at time t1 from this threshold point by point. Specifically, the calculation is as follows: ΔT1 = 2850N - 2795N = 55N, ΔT2 = 2865N - 2795N = 70N, ΔT3 = 2845N - 2795N = 50N, ΔT4 = 2860N - 2795N = 65N. The tension value of the wire rope at each lifting point is subtracted from the rated lifting threshold to form the corresponding difference sequence, thus generating the lifting point tension difference sequence.

[0058] The displacement difference judgment submodule calls the plate displacement and the support point bearing capacity value to perform point-by-point difference calculation, judges the obtained difference with the installation displacement threshold item by item, extracts the values ​​exceeding the installation displacement threshold and performs pairing statistics with the lifting point tension difference sequence to obtain the node offset difference set.

[0059] The system calculates the point-to-point difference between the plate displacement and the bearing capacity of the support points. It obtains the spatial coordinates of the four corner points of the plate in real time through four laser displacement sensors (numbered L1 to L4) arranged in the installation area, and compares them with the theoretical target coordinates in the digital design model to obtain the plate displacement. At the same time, the system collects the real-time bearing capacity values ​​from the pressure sensors integrated in the four temporary support points (numbered S1 to S4) below the installation position.

[0060] Table 1: Monitoring Data of Nodal Displacement and Bearing Capacity

[0061]

[0062] As shown in Table 1, this table lists the monitoring data of the four corner points of the board at a certain moment. The obtained differences are compared with the installation displacement threshold item by item. The difference calculation here determines the deviation between the actual bearing capacity and the theoretical bearing capacity caused by displacement. Theoretically, when uniformly positioned, the bearing capacity of the four points should be P. ideal =3439.8N / 4≈860N, the differences between the actual bearing capacity and the theoretical bearing capacity are ΔP1=900-860=40N, ΔP2=820-860=-40N, ΔP3=895-860=35N, ΔP4=845-860=-15N, respectively. The system will compare the displacement magnitude with the installation displacement threshold D. th The threshold D is compared. th The value is set to 10mm. This setting is based on finite element stress analysis and physical loading experiments on ALC plates. The results show that when the installation displacement deviation exceeds 10mm, the local stress generated inside the plate has a 5% probability of exceeding its crack resistance design strength. Taking monitoring point 2 as an example, its displacement is 12.0mm. This value exceeds the threshold. The system extracts the value of 12.0mm that exceeds the installation displacement threshold and performs pairing statistics with the lifting point tension difference sequence. If corner point 2 is controlled by lifting point C2, the displacement deviation of 12.0mm is paired with the C2 lifting point tension difference value of 70N calculated in the previous step and recorded as (node ​​2, displacement deviation: 12.0mm, tension deviation: 70N). This operation is repeated for all nodes that exceed the limit to obtain the node offset difference value set.

[0063] The path correction submodule calls the node offset difference set and compares it with the path node position data item by item. For nodes whose difference exceeds the installation displacement threshold, it performs position correction, replaces the corresponding path segment and recombines it to generate the board installation path adjustment instruction.

[0064] The system compares the node offset difference set with the path node position data item by item. The hoisting path of the system is predefined by a set of three-dimensional coordinate points, such as [Node1(0,0,8000), Node2(5000,0,8000),

[0065] ..., Node k (9990,5606,3004), ..., Node n [10000,5600,3000], where Node k It is the current path node that caused the deviation. n The final target node is the node whose physical location is closest to "Node 2" after the system receives the node offset difference set {Node 2: (displacement deviation: 12.0mm, tension deviation: 70N)} generated by the previous module. It first locates the path planning node Node that is closest to "Node 2" in physical location by calculating the spatial distance from the path node position data. k For nodes whose difference exceeds the installation displacement threshold, position correction is performed, i.e., based on the displacement deviation vector of node 2. (Its mold is 12.0mm) to adjust the Node k The coordinates of the new node. k_new The calculation method is as follows This correction operation generates a new path node by reverse-compensating for the deviation that has occurred, then replaces the corresponding path segments and recombines them. Specifically, during execution, the connecting nodes in the original path... k-1 To Node k and Node k To Node k+1 The two path segments were deleted and replaced with connections to Node. k-1 To Node k_new and Node k_new To Node k+1 For the two new path segments, the system uses a cubic spline interpolation algorithm to recalculate the transition trajectory between these two new path segments. The entire path node sequence is affected by Node k By Node k_new The system is updated and replaced, generating instructions for adjusting the board installation path.

[0066] Please see Figure 3 The seam correction module includes a seam difference calculation submodule, a cumulative amount recording submodule, and a positioning value correction submodule;

[0067] The seam difference calculation submodule calls the board installation path adjustment command, obtains the board positioning segment along the path, collects the measured width of the seam clamp and calls the design reference width, calculates the width difference of each path segment segment by segment, subtracts the corresponding design reference width from the measured width of each seam clamp segment, and generates a seam segment width difference sequence.

[0068] The system invokes the panel installation path adjustment command, from which it parses the precise alignment path segment before the panel is finally positioned. This path segment defines the movement trajectory of the panel as it slowly moves from a hovering position near the installation point to close to an adjacent installed panel. During this process, the splicing clamps located at the edge of the panel are activated, and their built-in laser rangefinders measure the gaps between the panels in real time, obtaining the measured width of the splicing clamps. For example, for a vertical splice of a panel, simultaneous measurements are taken at three positions (numbered W1, W2, W3) to obtain a set of measured width values ​​[11.5mm, 11.8mm, 11.4mm]. The system then retrieves the design baseline width W from the project database. d The reference width is set to 10mm according to the requirements of the "Autoclaved Aerated Concrete Building Construction" 06J104 atlas. The system calculates the width difference of each path segment segment by segment. Here, "segment" refers to different measurement points on the joint. The actual measured width of each joint clamp is subtracted from the corresponding design reference width. The calculation process is as follows: ΔW1=11.5mm-10mm=1.5mm, ΔW2=11.8mm-10mm=1.8mm, ΔW3=11.4mm-10mm=1.4mm. By repeatedly calculating all joint measurement points of the currently installed panels, a sequence of joint segment width differences is generated.

[0069] The cumulative value recording submodule performs a summation operation on all path segments according to the seam width difference sequence, records the current cumulative value after each segment, calculates the difference between the cumulative value and the seam allowable range, extracts the cumulative value segment that is close to the allowable range, and obtains the seam cumulative close value interval.

[0070] Based on the sequence of joint width differences, the system performs a term-by-term summation operation on all path segments, and maintains a cumulative joint width deviation value C for the entire wall surface. total Its initial value is 0. After each board is installed, the arithmetic mean of the differences between all the measurement points of the joints of that board is calculated and added to C. total superior.

[0071] Table 2: Calculation Table of Cumulative Deviation of Joint Width

[0072] Board number Average seam difference (mm) Cumulative seam difference (mm) P001 1.35 1.35 P002 1.50 2.85 P003 1.45 4.30 P004 1.20 5.50 P005 1.57 7.07 P006 1.20 8.27

[0073] Table 2 lists the calculation process for the cumulative deviation of the joint width after installing six consecutive panels. The system records the current cumulative value after each update for each segment and calculates the difference between this cumulative value and the allowable joint range R. sThe settings refer to the allowable deviation of the total length of the wall axis in the "Code for Acceptance of Construction Quality of Masonry Structures" (GB50203-2011). For a 10-meter-long wall, the total length deviation should not exceed ±10mm. Therefore, the allowable range for cumulative joint length is set to [-10mm, 10mm]. The system judges whether the current cumulative value is close to the boundary of the allowable range. Here, "close" is quantified as reaching 80% of the absolute value of the allowable range, that is, when |C total When |≥10mm×0.8=8mm, it is judged as close. After installing the 6th board, as shown in Table 2, the cumulative deviation is updated to C. total = 8.27mm. At this time, 8.27mm>8mm, the system extracts the cumulative value segment that is close to the allowable range, records the current board number (6th piece) and the current cumulative deviation value of 8.27mm, and obtains the cumulative close value range of the joint.

[0074] The positioning value correction submodule calls the path segment position corresponding to the cumulative proximity value interval of the joint, allocates the cumulative value of the current segment to the positioning positions of the subsequent three boards, calculates the equally distributed positioning offset value of a single board, and corrects the offset in the original positioning path to generate the board joint correction positioning value.

[0075] The system retrieves the path segment corresponding to the cumulative seam approach value interval. Based on the "6th board" information recorded in the previous module, it determines that the correction operation will begin from the installation of the 7th board. The cumulative value of 8.27mm in the current segment is allocated to the positioning positions of the subsequent three boards. That is, the cumulative deviation is absorbed by adjusting the seam width of the 7th, 8th, and 9th boards. The equally distributed positioning offset value of each board is calculated, and the correction amount to be ΔW for each board is determined. correct = -8.27mm / 3 ≈ -2.76mm, which means that the actual joint width of the subsequent three boards needs to be reduced by 2.76mm compared to the design baseline width of 10mm. The new target joint width W target The deviation is 10mm - 2.76mm = 7.24mm. The system corrects the offset in the original positioning path. Specifically, it modifies the three-dimensional coordinates of the endpoint of the final positioning path of the three boards. Taking the 7th board as an example, its original planned endpoint coordinates are shifted 2.76mm along the horizontal direction of the wall towards the 6th board, so that the final gap width is close to 7.24mm. The same positioning path correction is performed on the 8th and 9th boards. The reference benchmarks for their displacement are the final positions of the 7th and 8th boards after adjustment, respectively. In this way, the accumulated joint deviation is eliminated piece by piece, and the board joint correction positioning value is generated.

[0076] Please see Figure 4 The process connection module includes a time difference calculation submodule, a delay generation submodule, and a time interval correction submodule;

[0077] The time difference calculation submodule calls the board joint correction positioning value and performs positioning matching on the process number, collects the actual time consumption record of the corresponding process and calls the planned time consumption record of the process, calculates the time difference between the two in each process, subtracts the planned time consumption from the actual time consumption to form a difference list, and generates a process time difference sequence.

[0078] The system calls upon the joint correction positioning value of the panels and matches it with the process number. The process management module within the system assigns a unique process number to the installation process of each panel. For example, "P007-Installation" represents the installation process of the 7th panel. When the system generates the joint correction positioning value for the 7th panel, this instruction is automatically associated with the "P007-Installation" process. The system then starts a timer to collect the actual time recorded for the corresponding process. The start time of this record is when the hoist hangs the 7th panel, and the end time is when the panel is installed in place according to the corrected positioning value and completely separated from the hoist. For example, the recorded time for this complete process is 13.5 minutes. At the same time, the system calls upon the planned time record for the process, which is the planned time... The standard working time is based on statistical analysis of more than 1,000 uncorrected, standard installation operations. The average time to install a standard ALC board is determined to be 11 minutes, with a normal fluctuation range of ±1.5 minutes. Therefore, the planned time is taken as 11 minutes. The system calculates the time difference between the actual time and the planned time for each process, and subtracts the planned time from the actual time to form a difference list. For the process "P007-Installation", the time difference is 13.5min-11min=2.5min. This positive value indicates that this process is delayed by 2.5 minutes compared to the plan. The system performs this calculation for the installation of each board and stores the results in a sequence according to the process order, generating a process time difference sequence.

[0079] The delay generation submodule sums up each difference sequentially based on the process time difference sequence, records the cumulative value at each process node position in the cumulative result, compares the process delay range with the cumulative value of each node, extracts the node index that exceeds the process delay range, and obtains the process cumulative delay segment.

[0080] Based on the sequence of process time differences, the system sums up each difference in the sequence sequentially to track the cumulative time delay of the entire project. Assuming the cumulative delay is 28 minutes by the time the 6th board is installed, adding the 2.5-minute time difference for the 7th board results in a new cumulative delay of 28 min + 2.5 min = 30.5 min. The system records the cumulative value at each process node in the cumulative results, forming a cumulative delay time sequence that grows synchronously with the process. Subsequently, the system compares the process delay range with the cumulative value at each node. The process delay range R... t The setting is based on buffer time management in project management. For the ALC board installation, which is not an absolutely critical path, the project management plan sets the maximum allowed cumulative delay within half a working day (4-hour work system) to be 30 minutes. This threshold is obtained through project progress simulation calculation. If this range is exceeded, the work time adjustment plan needs to be activated. The system compares the current cumulative delay of 30.5 minutes with the upper limit of the delay range of 30 minutes. If 30.5 min > 30 min, it is considered true. At this time, the system extracts the node index that exceeds the process delay range, that is, records the process number "P007-Installation" that has exceeded the limit, and obtains the cumulative delay segment of the process.

[0081] The time interval correction submodule calls the list of subsequent processes corresponding to the cumulative delay segment of the process, proportionally distributes the time intervals of the three processes after the process node, calculates the time value to be deducted in each process and performs time interval adjustment, and establishes an installation process connection schedule.

[0082] The system retrieves the list of subsequent processes corresponding to the cumulative delay segment of the process. Based on the recorded over-limit node "P007-Installation", the system automatically identifies the three processes following it, namely "P008-Installation", "P009-Installation", and "P010-Installation". The system then proportionally distributes the time intervals of the three processes following this node. The current over-limit delay is 30.5min - 30min = 0.5min (i.e., 30 seconds). The system allocates this 30-second catch-up task... For the subsequent three processes, each process needs to be shortened by 30s / 3 = 10s. The time to be deducted from each process is calculated and the time interval is adjusted. In the original plan, the planned time for each process was 11 minutes. The system adjusts the planned time for processes "P008", "P009", and "P010" to 10 minutes and 50 seconds respectively. This adjustment will directly update the task instructions of the on-site construction terminal and the system's time assessment benchmark. Based on the latest planned time data of all processes, the system regenerates a dynamic construction schedule and establishes a timetable for the connection of installation processes.

[0083] Please see Figure 5 The node detection module includes a ratio extraction submodule, an interval judgment submodule, and an offset quantization submodule;

[0084] The ratio extraction submodule calls the installation process connection schedule, locates the process number of each support node, collects the bearing capacity test value of each node support point and calls the corresponding rated bearing capacity value, divides the bearing capacity test value of each support point by the rated bearing capacity value, arranges the ratio results according to the node order, and generates a support node bearing ratio sequence.

[0085] The system retrieves the installation process schedule and determines the currently executing process as "P011-Installation". It then locates the associated temporary support points S10, S11, S12, and S13. The system immediately collects the load-bearing capacity values ​​of each support point from the pressure sensors at these points, obtaining a set of real-time data, such as [880N, 855N, 865N, 870N]. Simultaneously, the system retrieves the corresponding rated load-bearing capacity value P. rated This rated value is calculated based on the standard weight of the plate and an ideal state of uniform distribution. Its value is approximately 3439.8 N / 4 ≈ 860 N. The bearing capacity test value at each support point is divided by the rated bearing capacity value, and the ratio results are arranged in node order. The calculation process is as follows: Ratio 10 =880N / 860N≈1.023, Ratio 11 =855N / 860N≈0.994, Ratio 12 =865N / 860N≈1.006, Ratio 13 =870N / 860N≈1.012. The system combines these calculated ratios in node order to generate a sequence of support node bearing ratios.

[0086] The interval judgment submodule calls the upper and lower limits of the allowable interval of bearing capacity item by item according to the bearing ratio sequence of the supporting nodes, judges whether each ratio exceeds the corresponding interval limit, records the node index position where the deviation occurs, extracts all deviation node numbers, and obtains the over-limit node index set.

[0087] Based on the bearing capacity ratio sequence of the support nodes [1.023, 0.994, 1.006, 1.012], the system sequentially calls the upper and lower limits of the preset allowable bearing capacity range. This allowable range is set based on structural safety redundancy and installation accuracy requirements. Through correlation analysis of bearing capacity data from numerous completed projects and the final structural stability, it is found that when the bearing capacity of a single support point deviates from the ideal value by more than ±2%, the long-term stability of the plate shows a slight deterioration trend. When the deviation exceeds ±5%, it is determined that there is a structural risk. Therefore, the allowable bearing capacity range R is set... pSet to [0.98, 1.02], which represents 98% to 102% of the rated load capacity, the system determines whether each ratio exceeds the corresponding range limit. The specific determination process is as follows: For Ratio 10 =1.023, which is considered a deviation because it exceeds the upper limit of 1.02, according to Ratio. 11 =0.994, since it falls within the range [0.98, 1.02], it is considered normal. Regarding Ratio... 12 =1.006, normal, for Ratio 13 =1.012, normal. The system records the node index position where the deviation occurred, i.e., node S10, and extracts all the deviation node numbers to obtain the out-of-limit node index set.

[0088] The offset quantization submodule calls the over-limit node index set to locate the node index number, re-acquires the corresponding ratio value for each node and performs difference processing with the boundary value of its interval, records the difference value as the offset amplitude value according to the node number, and summarizes them into a unified record in order to generate a support node bearing difference record.

[0089] The system calls the over-limit node index set {S10}, locates the node based on its index number, re-obtains its load-bearing ratio for each node, and performs difference processing on the value of the boundary of its interval. For node S10, its load-bearing ratio is 1.023, exceeding the upper limit of the allowable interval of 1.02. The system calculates its offset value as 1.023 - 1.02 = 0.003, which indicates that the actual load-bearing capacity of node S10 is 0.3% higher than the allowable upper limit. If the ratio of another node S15 is 0.975, which is lower than the lower limit of 0.98, its offset value is calculated as 0.975 - 0.98 = -0.005, indicating that its load-bearing capacity is 0.5% lower than the allowable lower limit. The system records this difference as the offset value according to the node number and summarizes the records of all over-limit nodes into a unified record in sequence. For example, a record may contain [node S10: +0.003, node S15: -0.005], generating a support node load-bearing difference record.

[0090] Please see Figure 6 The structure confirmation module includes a measurement difference extraction submodule, an interval offset judgment submodule, and a structure deviation annotation submodule;

[0091] The measurement difference extraction submodule calls the support node bearing difference record, obtains the plate number of the corresponding support node and locates its plate range, collects the flatness measurement value after the ALC plate is installed and calls the design median value of the flatness control range, subtracts the design median value from the flatness measurement value and arranges them in the order of the plates to generate the plate flatness difference sequence.

[0092] The system retrieves the support node bearing difference record. Based on the node number in the record, it first queries the installation database to identify the corresponding ALC plate number for each support node. For example, support nodes S10, S11, S12, and S13 collectively support ALC plate numbered P011. The system then locates the plate's area. After the installation of this plate and related procedures (such as grouting) are completed, the surface of plate P011 is scanned using a laser flatness measuring instrument mounted on the robot. The flatness measurement value of the ALC plate after installation is collected. The measuring instrument collects the three-dimensional coordinates of grid points at 50mm intervals within a 2-meter square area and uses the least squares method. An optimal reference plane is fitted, and the distance from all measurement points to this plane is calculated. The maximum absolute value is taken as the flatness measurement value of the panel. For example, if the measured value is 3.5mm, the system will then call the design median value of the flatness control range. According to the requirements for the flatness of general plastered walls in the "Standard for Acceptance of Construction Decoration and Renovation Engineering Quality" (GB50210-2018), the allowable deviation is ±3mm, and the design median value is 0mm. The flatness measurement value is subtracted from the design median value and arranged in panel order. For panel P011, the difference is 3.5mm-0mm=3.5mm. This operation is performed on all installed panels to generate a panel flatness difference sequence.

[0093] Table 3: ALC Panel Installation Quality Inspection Data Table

[0094] Segment number Support node carrying differences Flatness measurement (mm) P009 S06:+0.001 1.8 P010 S10:+0.003 2.5 P011 S14:-0.004 3.5 P012 S18:+0.002 2.1

[0095] As shown in Table 3, this table summarizes some key quality inspection data of ALC panels after installation, and records the abnormal load-bearing capacity of the support nodes during the process in relation to the final flatness measurement results.

[0096] The interval offset judgment submodule, based on the flatness difference sequence of the board, calls the upper and lower limits of the flatness control range, compares each item of the difference sequence with the upper and lower limits of the interval, extracts all board numbers that deviate from the interval boundary, and obtains the flatness deviation board index set.

[0097] Based on the flatness difference sequence of the boards and referring to the data in Table 3, which includes […, 1.8, 2.5, 3.5, 2.1, …], the system calls the upper and lower limits of the flatness control range, i.e., [-3mm, 3mm]. Each item in the difference sequence is compared with the upper and lower limits of the range. Specifically, for board P009, the difference is 1.8mm, which is considered acceptable since -3≤1.8≤3. For board P010, the difference is 2.5mm, which is considered acceptable since -3≤2.5≤3. For board P011, the difference is 3.5mm, which is considered unacceptable since 3.5>3. For board P012, the difference is 2.1mm, which is considered acceptable since -3≤2.1≤3. The system extracts all board numbers that deviate from the range boundary. In this example, only the flatness difference of board P011 exceeds the control range, thus obtaining the flatness deviation board index set.

[0098] The structural deviation annotation submodule calls the flatness difference value corresponding to each plate in the flatness deviation plate index set, divides the difference value range into multiple segments according to the preset interval, locates the interval segment to which each value belongs and records the interval identification, and combines the support node position number to perform annotation summary and generate ALC plate installation structure confirmation result.

[0099] The system retrieves the flatness difference value of 3.5mm corresponding to each plate in the flatness deviation plate index set {P011}. This difference value is then divided into preset severity level ranges. These ranges are set based on maintenance costs and the degree of impact on subsequent processes. For example, a deviation in the range (3.0, 4.0]mm is defined as "Level 1 Deviation," a deviation in the range (4.0, 5.0]mm is defined as "Level 2 Deviation," and a deviation exceeding 5.0mm is defined as "Severe Deviation." The current value of 3.5mm falls within the "Level 1 Deviation" range. Therefore, the system locates the range to which each value belongs and records the range identifier, thus marking the flatness status of plate P011 as "Level 1." The system then combines the support node location numbers to summarize the discrepancies. From Table 3, it is found that the bearing capacity difference record of the support node associated with panel P011 is "S14:-0.004". The system integrates these two pieces of information and outputs a comprehensive confirmation report. The report states that the final flatness of panel P011 exceeds the limit, with a deviation value of +3.5mm, classified as a Level 1 deviation. During installation, the associated support point S14 exhibited a -0.4% lower bearing capacity. This detailed information, including specific location, deviation value, deviation level, and process data traceability, is stored and displayed to obtain the ALC panel installation structure confirmation result.
