Description
Technical Field
[0001] The embodiments of the present application relate to the technical field of intelligent actual measurement and quantity, and in particular to a method and system for managing intelligent actual measurement and quantity of buildings. Background Art
[0002] In the process of modern building construction, it is crucial to capture in real time the environmental parameters of the building, the material flow path, and the spatial geometric information of key parts. The project team needs to accurately record the operation details, timestamps, and operator identity identifiers of each operation point at the construction site to ensure the transparency and traceability of the construction process. In addition, it is necessary to perform accurate mapping processing on the measured data, identify quality risk areas, and generate rectification suggestion reports to achieve efficient construction management and quality control.
[0003] Currently, most building projects rely on traditional paper records or simple spreadsheets to track construction progress and manage quality control.

[0018] Furthermore, by using distributed ledger technology in combination with homomorphic encryption algorithms based on the measurement dataset, the operation details, timestamps, and operator identity identifiers of all the actual measurement activities at each operation point on the construction site are encrypted to obtain encrypted operation records. The Byzantine fault-tolerant consensus mechanism is used to verify and reach a consensus among multiple system nodes, and the encrypted operation records are added to the blockchain to generate preliminary data logs. Further, graph theory analysis technology is applied to evaluate the dependency relationships between the operation points on the construction site, forming a dependency relationship model. Combining with the pre-established construction schedule, the on-site operation process is optimized and adjusted, and the distributed ledger technology and homomorphic encryption algorithms are used again for encrypted recording, finally generating data logs with anti-tampering characteristics. This method not only ensures the security and privacy protection of data, preventing the leakage of sensitive information, but also realizes the full transparency and traceability of the construction process through blockchain technology, enhancing the trust foundation for multi-party collaboration. At the same time, the application of graph theory analysis technology makes the dependency relationships between operation points clearly visible, helping to identify potential conflicts in advance and optimize the construction process, improving the construction efficiency and quality control level. In addition, the closed-loop quality management process promotes the effective implementation and continuous improvement of rectification measures, significantly enhancing the overall construction project management level and execution efficiency. In summary, this method effectively improves the data security, transparency, intelligence, and refinement degree of the building construction process, providing a solid guarantee for the smooth progress of the project.
[0019] Furthermore, by using augmented reality (AR) technology to overlay the BIM model according to the immutable data logs, the actual measurement data is accurately mapped to obtain a three-dimensional visualization interface. Based on this interface and combined with spatial analysis technology, the actual measurement data and preset standard data at each operation point on the construction site are compared to generate a deviation comparison result. Further, the support vector machine (SVM) algorithm is used to automatically classify and risk-assess the deviation data, identify the quality risk areas, generate a quality risk assessment report, and finally formulate targeted rectification measures by comprehensively considering the construction schedule and resource allocation factors to generate a rectification suggestion report. This method not only realizes the intuitive display and accurate mapping of the actual measurement data during the construction process, improving the visualization and understanding degree of the data, but also significantly enhances the efficiency and accuracy of quality management through automated deviation classification and risk assessment, ensuring that problems can be discovered and solved in a timely manner. In addition, the rectification measures formulated based on the quality risk assessment report are more scientific and reasonable, helping to optimize resource allocation and construction schedule arrangements, reducing the possibility of rework and delays. Overall, this method effectively enhances the quality control level during the construction process, promotes the scientific nature of multi-party collaboration and decision-making, and drives the development of building engineering management towards intelligence and refinement, providing a solid guarantee for the high-quality completion of the project.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.
[0026] Figure 1 There is provided a flowchart of a method for actual measurement and management of building intelligentization for an embodiment of the present application, as Figure 1 shown. The method includes: 101. Capture the environmental parameters, material flow paths, and spatial geometric information of key parts of the building during the construction process in real time to obtain a measurement dataset; In this step, capture the environmental parameters (such as temperature, humidity, etc.), material flow paths (including the specific transportation routes of materials from the warehouse to the construction site), and spatial geometric information of key parts of the building (such as the key dimensions and positions of the building structure) during the construction process in real time. These data are used to construct a comprehensive measurement dataset to ensure the accuracy and reliability of the basic data for subsequent analysis.
[0027] In the embodiment of the present application, various sensors and monitoring devices installed at the construction site are used to collect the above-mentioned various types of data in real time and transmit them to the central database for preliminary processing and storage, providing solid data support for subsequent encrypted records and dependency evaluations.
[0028] Suppose in a high-rise building project, an Internet of Things (IoT) sensor network is used to monitor environmental parameters such as temperature, humidity, and air quality at the construction site in real time; at the same time, RFID tags are used to track the flow paths of building materials, and a laser scanner is used to obtain the three-dimensional spatial geometric information of key parts of the building. All these data are centrally collected and stored in a cloud database to form a complete measurement dataset.
[0029] 102. Use distributed ledger technology combined with homomorphic encryption algorithms to encrypt the measurement dataset, record the operation details, timestamps, and operator identity identifiers of all actual measurement activities carried out at each operation point at the construction site in the encrypted state, and apply graph theory analysis technology to evaluate the dependencies between operation points at the construction site to generate a data log; In this step, use distributed ledger technology combined with homomorphic encryption algorithms to encrypt the operation details (such as operation types, tool usage), timestamps, and operator identity identifiers (such as employee numbers, job information) of all actual measurement activities carried out at each operation point at the construction site to ensure data security and privacy protection; apply graph theory analysis technology to evaluate the dependencies between operation points to generate a tamper-proof data log.
[0030] In the embodiment of the present application, the encrypted operation records are added to the blockchain, and the Byzantine fault-tolerant consensus mechanism is used to ensure that multiple nodes reach a consensus, thereby ensuring the authenticity and immutability of the data. Then, use graph theory analysis technology to establish a dependency relationship model between operation points to optimize the construction process.
[0031] Suppose in a bridge construction project, all on-site operations are recorded by mobile devices and immediately uploaded to the blockchain platform. Before each upload, the data is homomorphically encrypted to protect sensitive information. Then, the system automatically analyzes the logical sequence and mutual influence between different operation points, generates a data log reflecting the dependency relationship between operation points, ensuring that every step of the operation is traceable and tamper-proof.
[0032] 103. Use augmented reality technology to overlay the BIM model, perform precise mapping processing on the measured data in the data log, introduce the support vector machine algorithm to automatically classify and perform risk assessment processing on the deviation data between the measured data and the preset standard data, identify the quality risk area, and generate a rectification suggestion report, where the rectification suggestion report contains specific rectification measures for the quality risk area; In this step, according to the data log, use augmented reality (AR) technology to overlay the BIM model, perform precise mapping processing on the measured data actually measured at the construction site, introduce the support vector machine (SVM) algorithm to automatically classify and perform risk assessment processing on the deviation data between the measured data and the preset standard data, identify the quality risk area, and generate a rectification suggestion report.
[0033] In the embodiment of this application, by combining the BIM model with the actual construction scenario through AR technology, engineers can intuitively see the difference between the measured data and the preset standard data. The system uses the SVM algorithm to automatically classify the deviation data and evaluate the risk level, and finally generates a detailed rectification suggestion report to guide the on-site rectification work.
[0034] Suppose in a residential building construction, engineers wear AR glasses to view the construction site and intuitively compare the actual measurement results through the BIM model on the glasses screen. The system automatically detects that the thickness of some walls does not meet the design requirements and immediately generates a report containing specific rectification measures, prompting relevant personnel to correct the problem in time to avoid subsequent rework.
[0035] 104. Automatically match and assign the specific rectification measures formulated for the quality risk area according to the preset rules and weight scoring model, and by collecting feedback on the rectification effect, adjust the rules and methods for guiding the distribution of specific rectification measures to form a closed-loop quality management process.
[0036] In this step, automatically match and assign the specific rectification measures formulated for the identified quality risk area according to the preset rules and weight scoring model, and by continuously collecting feedback on the rectification effect, establish a performance evaluation system, and continuously adjust the rules and methods for guiding the distribution of specific rectification measures to form a closed-loop quality management process.
[0037] In the embodiments of the present application, the system automatically generates a task list based on the rectification suggestion report and assigns it to the corresponding responsible party according to the priority. Subsequently, the system tracks the execution progress and effect feedback of each task, dynamically adjusts the task assignment strategy to ensure the effective implementation of the rectification measures, and continuously improves the quality control level through the performance evaluation system.
[0038] Suppose in the construction of a commercial complex, the system assigns specific rectification measures to each discovered problem according to the rectification suggestion report, designates the responsible personnel and completion time limit. The system monitors the rectification progress in real time, collects feedback information, and adjusts the task assignment according to the actual situation to ensure that each quality problem can be solved efficiently. At the same time, a perfect performance evaluation system is established to supervise the whole rectification process.
[0039] In summary, steps 101 to 104 cover the whole process from data collection, encrypted recording, dependency assessment to quality risk identification and implementation of rectification measures, aiming to provide a highly transparent, secure and reliable closed-loop building construction quality management solution to meet the requirements of modern construction projects for high efficiency, high quality and high safety.
[0040] To solve the problems of insufficient data security and dependency assessment in existing construction management, in some embodiments, in step 102, the measurement data set is encrypted by using the distributed ledger technology combined with the homomorphic encryption algorithm, and the operation details, timestamps and operator identity identifiers of all actual measurement activities carried out at each construction site operation point in the encrypted state are recorded, and the graph theory analysis technology is applied to evaluate the dependencies between the operation points at the construction site to generate a data log, including: Using the distributed ledger technology combined with the homomorphic encryption algorithm, encrypt the operation details, timestamps and operator identity identifiers of all actual measurement activities carried out at each construction site operation point to obtain the encrypted operation records; according to the encrypted operation records, adopt the Byzantine fault-tolerant consensus mechanism to verify and reach a consensus among multiple system nodes in the distributed ledger technology, and add the encrypted operation records to the blockchain to generate a preliminary data log; use the preliminary data log, apply the graph theory analysis technology to model and analyze the dependencies between the operation points at the construction site to obtain a dependency model; based on the dependency model, combined with the construction progress plan formulated in advance according to the specific requirements and design requirements of the project, optimize and adjust the on-site operation process, and encrypt and record the optimized on-site operation process again by using the distributed ledger technology and the homomorphic encryption algorithm to generate a data log.
[0041] Using distributed ledger technology combined with homomorphic encryption algorithms, encrypt the operation details, timestamps, and operator identity identifiers of all actual measurement activities at each operation point on the construction site to obtain encrypted operation records; according to the encrypted operation records, adopt the Byzantine fault-tolerant consensus mechanism to verify and reach a consensus among multiple system nodes in the distributed ledger technology, and add the encrypted operation records to the blockchain to generate preliminary data logs; use the preliminary data logs and apply graph theory analysis technology to model and analyze the dependency relationships between operation points on the construction site to obtain a dependency relationship model; based on the dependency relationship model, combined with the construction schedule pre-developed by the project management team according to the specific requirements and design requirements of the project, optimize and adjust the on-site operation process, and encrypt and record the optimized process again using distributed ledger technology and homomorphic encryption algorithms to generate data logs.
[0042] In this embodiment, first, the operation details include information such as the specific construction operation type and the tools used; the timestamp ensures the time accuracy of each record; the operator identity identifier is used to confirm the specific person who performs the operation. Second, through encryption processing, it is ensured that these sensitive information is not tampered with or leaked during transmission and storage. Third, the dependency relationship model reflects the logical sequence and mutual influence between operation points, helping to identify critical paths and potential bottlenecks. Finally, the optimized and adjusted process is encrypted and recorded again, ensuring data consistency and security, and at the same time providing a basis for continuous improvement.
[0043] In the embodiment of the present application, first, by encrypting the data of all actual measurement activities, its security and privacy protection are ensured; second, the Byzantine fault-tolerant consensus mechanism is used to ensure data consistency among multiple nodes, and the encrypted operation records are added to the blockchain to generate preliminary data logs; third, a dependency relationship model between operation points is established through graph theory analysis technology to optimize the construction process; finally, combined with the pre-developed construction schedule, the optimized process is encrypted and recorded again to form the final data logs, ensuring a high degree of transparency and efficient management of the entire construction process.
[0044] Among them, the specific process of "using the preliminary data logs and applying graph theory analysis technology to model and analyze the dependency relationships between operation points on the construction site to obtain a dependency relationship model" includes: First, parse the unique identifiers of each operation point at the construction site from the preliminary data log, and extract the operation time sequence (including start / end timestamps), resource interaction records (equipment numbers, material batches, personnel IDs), and spatial coordinate information of each operation point. Use each operation point as a node to construct an initial node set. Among them, each node is attached with an attribute table, including operation types (such as steel bar binding, formwork installation), standard operation cycles (extracted from the BIM model), associated bill of materials (material specifications and quantities), and spatial positioning codes. The relevant information in the attached attribute table is parsed from the data log.
[0045] Secondly, based on the timestamp sequence, conduct a statistical analysis of the operation intervals between adjacent operation points. The process of statistical analysis includes: calculating the time interval distribution of each pair of operation points, setting a dynamic threshold (such as 30% of the average operation cycle), and determining whether there is a mandatory sequence dependency based on whether the time interval distribution is greater than the dynamic threshold. For the operation point pairs with mandatory sequence dependencies (A→B), generate directed time sequence edges. The weight of the directed time sequence edge is the standard deviation of the time interval (reflecting the time sequence stability), and mark the mandatory sequence clause numbers in the construction specifications. Finally, output the directed graph skeleton with time sequence constraints (hereinafter referred to as: time sequence graph skeleton) as the baseline structure for subsequent analysis.
[0046] Then, on the basis of the time sequence graph skeleton, introduce resource interaction data and continue to optimize the time sequence graph skeleton to obtain a hybrid graph structure. Among them, resource interaction data refers to the data in which a certain interaction exists between this operation point and other operation points.
[0047] The specific process includes: counting the resource overlap times and durations of operation points with shared equipment (such as tower crane usage records) or cross personnel (records of the same work team across operation points), calculating the resource coupling coefficient (such as resource coupling coefficient = number of shared resources / total number of resources); for operation point pairs with a resource coupling coefficient exceeding the preset threshold (such as ≥0.6), add undirected resource edges. The weight of the undirected resource edge is the resource coupling coefficient, and record conflict events (such as the number of times of equipment waiting timeout); and superimpose the undirected resource edges on the time sequence graph skeleton to form a hybrid graph structure (that is, a hybrid graph structure refers to a graph structure that simultaneously includes directed time sequence edges and undirected resource edges).
[0048] Furthermore, a hybrid graph is used for topological feature analysis. The topological feature analysis process includes: applying the k-core decomposition algorithm to iteratively strip low-connectivity nodes, identifying high-density dependent subgraphs (core regions with k≥3), and labeling them as potential key job groups; screening key subgraphs in the potential key job groups (specifically set according to requirements), and running the weighted PageRank algorithm within the key subgraphs (using the weights of directed time-series edges and undirected resource edges as transition probability parameters) to calculate the node centrality scores, and screening the top 10% of the nodes as hub nodes (for example, the concrete pouring point has a significantly higher score due to its dependence on formwork acceptance and steel bar inspection); finally, based on the dynamic programming algorithm, calculate the longest path of the hub nodes under time-series constraints, mark it as the critical path chain, and associate the parallel job points affected by it.
[0049] For example, the specific process of calculating the critical path chain based on the dynamic programming algorithm under time-series constraints is as follows: First, based on the previously corrected acyclic hybrid graph, normalize the PageRank centrality scores of the hub nodes into priority weights, and combine the directional constraints of time-series edges (forcing the construction sequence) and the coupling strength of resource edges (shared resource stability) to construct a directed acyclic graph (DAG) with multiple weights. , where represents the longest weighted path value reaching node v. The weights incorporate the standard deviation of time-series edges (reflecting the stability of process connection) and the resource coupling coefficient (reflecting the collaborative efficiency). At the same time, a virtual node connection mechanism is introduced for parallel branch nodes to handle multi-predecessor dependencies. Then, starting from all starting points with an in-degree of 0, iteratively calculate the dp values of each node in topological sorting order and record the predecessor node chain. Finally, select the path with the largest dp value as the critical path chain. Finally, by traversing the nodes on the critical path chain in reverse, extract the directly associated parallel job points (non-critical path nodes that satisfy the spatial distance ≤5 meters and the resource coupling degree ≥0.4), establish an influence relationship matrix to label the dependence type (strong resource dependence / weak time-series dependence), and finally form a construction network topological structure including the main path and 23 associated parallel branches.
[0050] Even further, a deep verification of the hybrid graph is carried out. The deep verification process includes: executing the topological sorting algorithm to detect cyclic dependence chains (such as A→B→C→A), and combining the spatial topological relationship of the BIM model to locate the dead loops caused by design conflicts or process mismatches; applying the maximum flow-minimum cut theorem, using the production capacity of job points (quantity completed per unit time) as the capacity value, analyzing the flow bottlenecks on resource edges, and identifying the minimum production capacity improvement points corresponding to the cut sets (for example, adding a pump truck can increase the concrete supply flow by 50%).
[0051] Furthermore, when constructing the dependency relationship model based on the comprehensive topological feature analysis and the deep verification results, the following integration process is specifically executed: First, based on the key subgraphs identified by k-core decomposition (k≥3 regions), construct an attribute adjacency matrix in the blocked compressed sparse row (BCSR) format. Encode the time-series edge direction, the standard deviation of the time interval, and the corresponding specification clauses as non-symmetric elements of the matrix, record the resource edge coupling coefficient and the number of conflicts as symmetric elements, and divide independent data blocks for the key subgraphs to accelerate high-frequency access; Secondly, integrate the PageRank hub node list and the critical path chain data to establish a multi-layer adjacency list structure: embed the PageRank value, the k-core level, and the critical path identifier (derived from the topological feature analysis) at the node layer, associate the time-series / resource weight parameters and the bottleneck level obtained from the maximum flow-minimum cut analysis (such as the "high-priority capacity expansion edge" mark) at the edge layer, and mount the loop dependency chain correction record (from the Tarjan algorithm detection result) and the BIM space collision verification log at the event layer; Then, map the visualization rules: drive the node radius scaling based on the normalized PageRank value (in the range of 0-1) of the hub node (basic radius 20px + score × 50px), distinguish the dependency types by the red transparency of the time-series edge (1 - time interval stability coefficient) and the blue saturation of the resource edge (coupling coefficient × 100%), use the pulse mutation light effect for the critical path chain (frequency = 1 / total path duration) and superimpose parallel branches connected by virtual nodes (filter nodes with a spatial distance ≤ 5 meters and a resource coupling degree ≥ 0.4); Finally, inject the deep verification results: mark the loop dependency correction status (such as "passed the BIM space topology verification") in the edge attributes of the adjacency list, bind the corresponding production capacity improvement plan for the cut set (such as the coordinate points for additional pump trucks) as metadata to the resource edge, and achieve spatial grid alignment with the BIM model (error ≤ 0.1 meters) through the 3D rendering engine of Cytoscape.js to form a dynamic iterable model that simultaneously includes construction logic dependencies, resource bottleneck warnings, and spatial conflict hotspots, that is, the dependency relationship model.
[0052] Finally, connect the dependency relationship model to the construction Internet of Things system: when new measured data triggers a change in the dependency relationship (such as a resource coupling break due to equipment failure), automatically recalculate the k-core subgraph and the critical path chain, and push warnings to the associated operation points; verify the prediction accuracy of the model through historical data playback (such as determining it is effective when the critical path delay and the actual progress deviation ≤ 5%), and dynamically adjust the threshold parameters (such as the resource coupling coefficient threshold adapting from 0.6 to 0.55).
[0053] Through progressive analysis of timing constraints → resource coupling → topological features → bottleneck diagnosis, this process transforms the original log into a quantifiable, traceable, and predictable dependency model, providing a decision-making basis at the topological level for construction scheduling optimization.
[0054] The following is a specific example: Suppose in a large industrial park construction project. First, all on-site operations (such as concrete pouring and steel structure installation) are recorded in real time through intelligent devices and immediately uploaded to the blockchain platform. Before each upload, the data is homomorphically encrypted to protect sensitive information. Second, the system automatically verifies the authenticity of each operation record and adds it to the blockchain to generate a preliminary data log. Third, engineers use graph theory analysis techniques to construct a dependency model between operation points, identifying which tasks are on the critical path and which tasks can be executed in parallel, thus optimizing the construction process. Finally, the records are re-encrypted according to the optimized process to ensure data consistency and security, and at the same time, a basis for continuous improvement is established. Through the above steps, the full process automation and intelligence from data collection to process optimization and then to security management are achieved, significantly improving construction quality and efficiency.
[0055] To address the problem of insufficient data verification and consistency confirmation in existing construction management, in some embodiments, based on the encrypted operation records, a Byzantine fault-tolerant consensus mechanism is used to verify and reach a consensus among multiple system nodes in distributed ledger technology, and the encrypted operation records are added to the blockchain to generate a preliminary data log, including: Using a Byzantine fault-tolerant consensus mechanism, perform validity verification processing on the encrypted operation records corresponding to each measured activity to obtain verification results; based on the verification results, perform consistency confirmation processing among multiple system nodes in distributed ledger technology to generate a consensus decision; use the consensus decision to add the encrypted operation records to the blockchain to form a block structure and synchronize it to all system nodes in distributed ledger technology to obtain block-structured operation records; apply graph theory analysis techniques to evaluate the dependencies between operation points at the construction site, and at the same time integrate all block-structured operation records to generate a preliminary data log.
[0056] In this embodiment, first, the verification results include whether the encrypted records of each measurement event meet the preset security standards and logical rules; second, the consensus decision refers to ensuring that multiple nodes reach a consensus on the same transaction or record through a Byzantine fault-tolerant consensus mechanism; third, the block structure is the basic unit of the blockchain, containing a series of verified operation records to ensure data immutability; finally, the dependency model reflects the logical order and mutual influence between operation points, helping to identify the critical path and potential bottlenecks. These concepts work together to ensure the security and reliability of construction data.
[0057] In the embodiments of the present application, first, the system uses the Byzantine fault-tolerant consensus mechanism to verify the validity of the encrypted records of each measurement event to ensure its authenticity and integrity; second, based on the verification results, consistency confirmation is carried out among multiple system nodes to generate a consensus decision to ensure data consistency; third, using the consensus decision, the encrypted operation records are added to the blockchain in the form of blocks and synchronized to all participating nodes to form block-based operation records; finally, the system applies graph theory analysis technology to evaluate the dependency relationships between work points, and at the same time integrates all block-based operation records to generate preliminary data logs to ensure the high transparency and efficient management of the entire construction process.
[0058] The following is a specific example: Suppose in a large bridge construction project, first, the system uses the Byzantine fault-tolerant consensus mechanism to verify the encrypted records of each operation such as concrete pouring and steel bar binding to ensure the authenticity and integrity of each record; second, multiple system nodes (such as the construction party, supervision party, and design party) carry out consistency confirmation based on the verification results to generate a consensus decision to ensure that all participating parties reach an agreement on the same record; third, the system adds these verified operation records to the blockchain in the form of blocks and synchronizes them to all participating nodes to form block-based operation records to ensure that the data is tamper-proof and traceable throughout the process; finally, engineers use graph theory analysis technology to evaluate the dependency relationships between different work points, and at the same time integrate all block-based operation records to generate detailed preliminary data logs to ensure the optimization of the construction process and the timely discovery and solution of quality problems. Through the above steps, the full process automation and intelligence from data verification to consistency confirmation and then to dependency relationship evaluation are realized, significantly improving the construction quality and efficiency.
[0059] To solve the problems of insufficient optimization of the operation process and inadequate data security protection in existing construction management, in some embodiments, based on the dependency relationship model, combined with the construction schedule plan formulated in advance according to the specific requirements and design requirements of the project, the on-site operation process is optimized and adjusted, and the optimized on-site operation process is encrypted and recorded again using distributed ledger technology and homomorphic encryption algorithm to generate data logs, including: Using the said dependency model, model and analyze the dependencies between various operation points at the construction site to obtain the dependency analysis result; according to the said dependency analysis result, combined with specific requirements and the construction schedule plan, optimize and adjust the on-site operation process to generate an optimized on-site operation process plan; based on the said optimized on-site operation process plan, apply distributed ledger technology and homomorphic encryption algorithm to encrypt the details of each activity operation, timestamp and operator identity identifier in the on-site operation process plan to obtain an encrypted optimized operation process record; according to the said encrypted optimized operation process record, adopt the Byzantine fault-tolerant consensus mechanism to verify and reach a consensus among multiple system nodes in the distributed ledger technology, add the said encrypted optimized operation process record to the blockchain to form a block structure, and synchronize it to all system nodes to obtain a block-structured optimized operation process record; use the said block-structured optimized operation process record to integrate all block-structured information related to the optimized on-site operation process to generate a data log.
[0060] In this embodiment, first, the dependency model includes the logical sequence, time dependency and resource dependency between each operation point, and is used to identify the critical path and potential bottlenecks; second, the construction schedule plan is a timetable pre-developed by the project management team, which clarifies the key milestones and time nodes of each construction stage to ensure the project is completed on time; third, the optimized on-site operation process refers to the new operation process optimized by the dependency model and the schedule plan, aiming to improve efficiency and quality; finally, the data log is the operation record encrypted by the distributed ledger technology and the homomorphic encryption algorithm to ensure the security and immutability of the data.
[0061] In the embodiment of the present application, first, the system uses the dependency model to analyze the dependencies between various operation points at the construction site, and combines the construction schedule plan pre-developed according to the specific requirements and design requirements set by the project to optimize and adjust the on-site operation process; second, the optimized operation process is re-evaluated to ensure that all critical paths and potential bottlenecks have been effectively handled; third, the system uses the distributed ledger technology and the homomorphic encryption algorithm again to encrypt and record the optimized on-site operation process to ensure that each step of the new process is securely recorded; finally, the generated data log not only contains the details of the optimized operation process, but also ensures the security and immutability of all data.
[0062] The following is a specific example: Suppose in a high-rise residential building construction project. First, the engineer uses the dependency relationship model to analyze the dependency relationships among various operation points at the construction site, and combines the construction schedule plan pre-established according to the specific requirements and design requirements set by the project to optimize and adjust the on-site operation process. For example, adjust the priorities of certain processes or reallocate resources. Second, the project manager combines the optimized operation process with the existing schedule plan to ensure that all critical paths and potential bottlenecks are effectively addressed. Third, the system uses distributed ledger technology and homomorphic encryption algorithms to encrypt and record the optimized on-site operation process again to ensure that every operation step in the new process is securely recorded, forming an updated data log. Finally, the generated data log not only contains the details of the optimized operation process but also ensures the security and immutability of all data. Through the above steps, the full process automation and intelligence from dependency relationship modeling to operation process optimization and then to data security processing are achieved, significantly improving the construction quality and efficiency.
[0063] This application takes into account that in order to solve the problems of insufficient data security and integrity in existing construction management, especially the risk that sensitive information is easily tampered with or leaked. This application further provides an alternative solution. In the prior art, due to problems such as insufficient data encryption strength, lax permission control, and improper time window management, the operation records during the construction process cannot be effectively protected, thus affecting the construction quality and safety. Therefore, the inventive embodiments propose this alternative solution. By introducing distributed ledger technology and homomorphic encryption algorithms in combination with multi-dimensional data analysis and role-based access control models, it is ensured that the operation details, timestamps, and operator identity identifiers of all measurement events are processed in an encrypted state, and the immutability and confidentiality of the data are enhanced through a series of complex security mechanisms to solve the above technical problems.
[0064] Optionally, using the distributed ledger technology in combination with the homomorphic encryption algorithm to encrypt the operation details, timestamps, and operator identity identifiers of all measurement events to obtain encrypted operation records, including: Clean, standardize, and perform multi-dimensional data analysis on the measurement data set, and prepare a secure environment through a role-based access control model and a time lock mechanism; ; Among them, represents the encrypted operation record; is the homomorphic encryption algorithm used to ensure that certain types of operations can still be performed on the data in the encrypted state; is the operation details including the operation content of the specific measurement event; is the timestamp indicating the exact time point of each operation; The operator identity identifier confirms the legitimacy of the operator by comparing with a pre-registered identity information database; The public key is used to encrypt sensitive information to ensure that only the recipient with the corresponding private key can decrypt it; After the calculation is completed, the hash function is used to enhance the immutability, the weight is adjusted in combination with the permission level, the influence of the time window is considered, a random salt value is added to prevent attacks, the record length is calculated and the authenticity is verified, and finally the comprehensive encryption strength is evaluated ; ; Among them, represents the comprehensive encryption strength; The SHA-256 hash function is used to enhance the immutability of data; is the encrypted operation record obtained from the first formula; The role-based weight function reflects the influence of different permission levels on the encryption strength; is the operator's permission level; The time window function adjusts the encryption strength according to the valid time period; is the valid time window to ensure that the encryption is valid within a specific time period; The length function calculates the length of the encrypted record to increase the complexity; The random salt value increases the randomness and uniqueness of the hash result to prevent rainbow table attacks; and are non-linear adjustment parameters used to adjust the non-linear characteristics of the overall encryption strength; The private key is used to verify the identity during decryption; The verification function ensures the authenticity and integrity of the encrypted record; According to the results, the encryption parameters are optimized, the Byzantine fault-tolerant consensus mechanism is applied to verify and synchronize the encrypted record to the blockchain, and integrity verification is performed to generate the encrypted operation record.
[0065] This formula aims to, firstly, ensure that certain types of operations can still be performed on the data in the encrypted state; secondly, enhance the immutability of the data to prevent malicious attacks; thirdly, adjust the encryption strength according to the permission level, consider the influence of the time window, and add a random salt value to improve the randomness and uniqueness of the hash result; finally, calculate the record length and verify the authenticity, and evaluate the comprehensive encryption strength . These steps work together to ensure the security and reliability of each operation record during the construction process.
[0066] The following briefly introduces the design reasons for each item of this formula: ; Operation Details : The operation content of specific measurement events is used to describe the specific situation of each operation in detail; Timestamp : Ensure the accuracy of the time point of each operation; Operator Identification : Confirm the legitimacy of the operator by comparing with the pre-registered identity information database; Public Key : Used to encrypt sensitive information to ensure that only the recipient with the corresponding private key can decrypt it; The following briefly introduces the acquisition methods of each parameter of this formula: Operation Details and Timestamp from the real-time collected data set; Operator Identification Obtained through the identity authentication system; Public Key Obtained from the security certificate authority.
[0067] The following briefly introduces the design reasons for each item of this formula:
[0068] ; Hash Function : The main purpose of introducing the hash function is to enhance the immutability of data. By applying the SHA-256 hash algorithm to the encrypted operation record a unique hash value is generated to ensure that any modification to the original data can be immediately detected, thereby improving the integrity and anti-tampering ability of the data.
[0069] Role-based Weight Function and Time Window Function : These two functions work together to adjust the encryption strength according to the operator's permission level and the valid time period of the operation. Users with different permission levels have different security requirements for the system, and the time window function ensures that the encryption is valid within a specific time period to prevent the misuse or abuse of expired data. This design enhances the flexibility and adaptability of the system and can better meet different application scenarios and security requirements.
[0070] Length Function and Random Salt Value : By calculating the length of the encrypted record and adding a random salt value, the complexity and uniqueness of the encryption result are increased. This not only improves the randomness of the hash result but also effectively prevents common cracking methods such as rainbow table attacks, further enhancing the security of the data.
[0071] Exponential Function : This part is used to combine the private key and Verification Function , ensuring that only the recipient with the correct private key can decrypt and verify the authenticity and integrity of the encrypted record. The introduction of the non-linear adjustment parameter makes the adjustment of the overall encryption strength more flexible and can dynamically optimize the encryption effect according to the actual situation.
[0072] The following briefly introduces the acquisition methods of each parameter in this formula:
[0073] Hash function Use the standard library function; the encrypted operation record Obtained from the first formula; role-based weight function Defined according to the user role; permission level Obtained from the permission management system; time window function Dynamically calculated according to the preset rules; valid time window Set by the system administrator; length function Directly calculate the string length; random salt value Randomly generated; non-linear adjustment parameter and Set by experts; private key Obtained from the security certificate center; verification function Use the standard library function.
[0074] Suppose in a large bridge construction project. First, the system cleans, standardizes, and performs multi-dimensional data analysis on the measurement data set, and prepares a secure environment through the role-based access control model and the time lock mechanism; then, the system uses the homomorphic encryption algorithm for the operation details , timestamp and the operator's identity identifier to perform encryption processing, obtaining the encrypted operation record , where , for example ; then, after calculating , the system enhances the non-forgeability through the hash function , adjusts the weight in combination with the permission level, considers the influence of the time window, adds a random salt value to prevent attacks, calculates the record length and verifies , assuming ; finally, optimize the encryption parameters according to the result, apply the Byzantine fault-tolerant consensus mechanism to verify and synchronize the encrypted record to the blockchain, and perform integrity verification to generate the encrypted operation record.
[0075] Through the above steps, the full - process automation and intelligence from data cleaning to encryption processing and then to comprehensive encryption strength assessment are achieved, significantly improving the security and reliability of each operation record during the construction process. Assuming the set threshold is 0.95, since is greater than the set threshold, it indicates that the encryption strength is high enough to effectively prevent data tampering or leakage, ensuring the construction quality and security.
[0076] To solve the problem of inaccurate mapping and deviation assessment of measured data in existing construction management, in some embodiments, in step 103, the use of augmented reality technology to overlay the BIM model is used to accurately map the measured data in the data log, and the support vector machine algorithm is introduced to automatically classify and risk - assess the deviation data between the measured data and the preset standard data to identify the quality risk area and generate a rectification suggestion report. The rectification suggestion report contains specific rectification measures for the quality risk area, including: Using augmented reality technology to overlay the BIM model to accurately map the measured data of each operation point at the construction site in the data log, obtaining a three - dimensional visualization interface; based on the three - dimensional visualization interface, combining spatial analysis technology to compare the measured data with the preset standard data to generate deviation data; introducing the support vector machine algorithm to automatically classify and risk - assess the deviation data, identify the quality risk area, and generate a quality risk assessment report; according to the quality risk assessment report, comprehensively considering construction progress and resource allocation factors, formulating targeted rectification measures to generate a rectification suggestion report.

[0079] The following is a specific example: Suppose in a high-rise residential building construction project, first, the engineer wears AR glasses to view the construction site and visually compare the actual measurement results with the BIM model on the glasses screen to form a three-dimensional visualization interface; second, the system automatically detects and records the actual measurement values of all key parts (such as wall thickness, steel bar spacing, etc.) and compares them with the preset standard data to generate a detailed deviation comparison result; third, the system uses the support vector machine algorithm to classify and risk-assess these deviation data, identifies that the thickness of some walls does not meet the design requirements, immediately generates a report containing specific rectification measures, and prompts relevant personnel to correct the problem in a timely manner to avoid subsequent rework; finally, the project manager formulates specific rectification measures based on the content in the quality risk assessment report, comprehensively considering the current construction progress and available resources, to ensure that each quality problem can be efficiently solved. Through the above steps, the full process automation and intelligence from data mapping to deviation assessment and then to the implementation of rectification measures are realized, significantly improving the construction quality and efficiency.

[0081] In this embodiment, first, the deviation data includes the differences between the actual measurement values of each working point at the construction site and the preset standards, which is used to identify potential problems during the construction process; second, the classification result is obtained by automatically classifying the deviation data through the support vector machine (SVM) algorithm, distinguishing different types of deviations; third, the risk assessment conclusion refers to identifying which areas have significant quality risks through further analysis of the classified deviation data; finally, the quality risk assessment report is a document generated by comprehensively organizing all the identified quality risk information, providing detailed suggestions for rectification measures to ensure that problems can be solved in a timely and effective manner.
[0082] In the embodiment of the present application, first, the system uses the deviation data and introduces the support vector machine algorithm to perform automatic classification processing on it to generate a classification result; second, according to the classification result, the system applies the support vector machine algorithm again to perform risk assessment processing on the classified deviation data, identifies specific quality risk areas, and generates a risk assessment conclusion; third, based on the risk assessment conclusion, the system comprehensively organizes all the identified quality risk information; finally, the system generates a detailed quality risk assessment report, provides specific suggestions for rectification measures, and ensures that each quality problem can be solved efficiently.
[0083] The following is a specific example: Suppose in a large bridge construction project, first, engineers collect the deviation data of each working point at the construction site, including the differences between the actual measurement values such as wall thickness and steel bar spacing and the design standards; second, the system uses this deviation data and introduces the support vector machine algorithm to perform automatic classification processing on it to generate a classification result, for example, some wall thicknesses do not meet the standards, while there are problems with the steel bar spacing in some areas; third, according to the classification result, the system applies the support vector machine algorithm again to perform risk assessment processing on the classified deviation data, identifies specific quality risk areas, and generates a risk assessment conclusion, such as some wall thickness deviations may affect the structural safety; finally, based on the risk assessment conclusion, the system comprehensively organizes all the identified quality risk information, generates a detailed quality risk assessment report, and provides specific suggestions for rectification measures, such as increasing the wall thickness or adjusting the steel bar spacing. Through the above steps, the full process automation and intelligence from deviation data classification to risk assessment and then to rectification measure suggestions are realized, significantly improving the construction quality and efficiency.
[0084] This application takes into account that in order to solve the problems of inaccurate classification of deviation data and risk assessment in existing construction management, especially the difficulty in effectively identifying key quality risk areas and prioritizing them, this application further provides an alternative solution. In the prior art, due to problems such as simple deviation data processing methods, lack of spatial distribution analysis, and insufficiently intelligent risk assessment models, potential quality risks have not been discovered and processed in a timely manner. Therefore, the inventive embodiments propose this alternative solution, which comprehensively evaluates and automatically classifies deviation data by introducing the support vector machine algorithm combined with hash function mapping, quality voting mechanism, and multi-dimensional data analysis technology, and generates a detailed quality risk assessment report to solve the above technical problems.

[0086] Among them, represents the risk score of each deviation point; is used by the support vector machine algorithm for automatic classification and evaluation; is the difference data extracted from the deviation comparison result; is the hash function mapping, is the hash function (such as SHA-256), is the hash function parameter for adjusting the spatial distribution of the difference data; is the weight function based on quality voting, represents the quality influencing factors of each deviation point; is a non-linear adjustment parameter for adjusting the non-linear characteristics of the score; is the region function, represents the location information of the deviation point, used to adjust the risk score according to the location; After calculating , integrate the risk scores of all deviation points, combine the regional influence coefficient and timestamp information, adjust the score through the time deviation function, and apply matrix transformation technology to integrate multi-dimensional data into a one-dimensional format. Highlight the key risk areas identified as having a relatively high risk score after being evaluated by the support vector machine algorithm according to the priority adjustment factor, and generate a quality risk assessment report; among them, the quality risk assessment report is calculated by the following formula: ; Among them, represents a quality risk assessment report; and are non-linear functions used to adjust the report generation method; is the risk score of the is the th deviation point; is the influence coefficient of the region where the th deviation point is located, considering the importance of different regions; is the total number of deviation points; is a matrix transformation function used to integrate multi-dimensional data into a one-dimensional report format; is a priority adjustment factor to ensure that key risk areas are highlighted in the report.
[0087] This formula aims to achieve intelligent classification and risk assessment of deviation data by comprehensively evaluating the deviation comparison results and analyzing the spatial distribution, and introducing advanced machine learning and support vector machine algorithms. Specifically, first, the system prepares the input data using a hash function mapping and a quality voting mechanism to ensure that each deviation point can obtain a reasonable weight according to its spatial distribution and quality influencing factors; second, through the support vector machine algorithm classifies the deviation data, and adjusts the risk score in combination with the regional location to ensure the accuracy and rationality of the score; third, the system integrates the risk scores of all deviation points, considers the regional influence coefficient and timestamp information, and applies matrix transformation technology to integrate multi-dimensional data into a one-dimensional format to highlight key risk areas; finally, generates the final quality risk assessment report, and ensures the rationality and accuracy of the conclusion through visualization tools and expert reviews. These steps work together to ensure the effective processing and risk assessment of each piece of deviation data during the construction process, improving construction quality and safety.
[0088] The following briefly introduces the design reasons for each item of this formula: ; Differential data : The differential data extracted from the deviation comparison results is used as the input for the support vector machine algorithm; Hash function mapping : Ensure that the spatial distribution characteristics of the differential data are fully considered; Weight function based on quality voting : Assign weights according to the quality influencing factors of each deviation point; : This part is used to adjust the risk score according to the position information of the deviation point to ensure that the score can reflect the impact of different positions on the overall construction quality. By introducing a non-linear adjustment parameter and the regional function , the system can dynamically adjust its risk score according to the specific location of the deviation points, so that the deviations in the critical area receive higher attention, thereby improving the accuracy and pertinence of risk assessment.

[0090] The following briefly introduces the design reasons for each item in this formula: ; : This part is used to integrate the risk scores of all deviation points and conduct a comprehensive evaluation by combining the regional influence coefficient and timestamp information. By weighting and summing the risk scores of each deviation point, the regional influence coefficient and the time deviation function and then applying the nonlinear function for adjustment, it ensures that the final score can comprehensively consider the influence of spatial distribution and time factors, improving the scientificity and rationality of the evaluation result. : This part is used to integrate multi-dimensional data into a one-dimensional report format and highlight critical risk areas according to the priority adjustment factor. By using the matrix transformation function to simplify the multi-dimensional data into an easy-to-understand one-dimensional format, and at the same time applying the priority adjustment factor to ensure that important risk areas are highlighted in the report. This design not only improves the readability and practicality of the report, but also ensures that key issues can be discovered and processed in a timely manner, enhancing the effect of construction management and quality control.

First, the system comprehensively evaluates the deviation comparison results and conducts spatial distribution analysis, identifies significant deviations in the thickness of certain walls and the positions of structural supports, and performs priority ranking; then, a quality voting mechanism is introduced to assign weights to each deviation point, preparing the input data required for the support vector machine algorithm, such as , suppose ; then, the system integrates the risk scores of all deviation points, combines the regional impact coefficient and timestamp information, adjusts the scores through the time deviation function, and applies matrix transformation technology to integrate multi-dimensional data into a one-dimensional format, highlighting key risk areas according to the priority adjustment factor, such as , suppose ; finally, review the content of the report to ensure accuracy, use visualization tools to convert the data into charts, introduce expert reviews to ensure the rationality of the conclusions, and distribute the report to the responsible parties, establishing a tracking mechanism to monitor the implementation progress of the rectification measures.
[0093] Through the above steps, the full process automation and intelligence from the comprehensive evaluation of deviation data to automatic classification and risk assessment and then to report generation are realized, significantly improving the processing accuracy of each deviation data and the accuracy of risk assessment during the construction process. Suppose the set threshold is 0.85, because and are both greater than the set threshold, so it shows that the system can effectively identify and highlight key quality risk areas, ensuring the construction quality and safety.
[0094] To solve the problems of unscientific distribution of rectification measures and lagging performance evaluation in existing construction management, in some embodiments, in step 104, the specific rectification measures formulated for the identified quality risk areas are automatically matched and assigned according to the preset rules and weight scoring model.
