Abstract
Description
Technical Field
[0001] The present application relates to the technical field of anomaly recognition, and specifically to an intelligent construction information anomaly recognition method. Background Technique
[0002] In the field of construction, it is crucial to ensure the smooth progress and construction safety of the construction process. In traditional construction management, manual inspections and experience-based judgments are often relied on to detect anomalies during construction. However, this approach has many limitations, specifically manifested in:
[0003] On the one hand, it is difficult for manual inspections to achieve full-scale and real-time monitoring of the construction process, and it is easy to miss some potential anomaly information. For example, minor faults in construction equipment may not be easily detected in the initial stage, and these faults may gradually develop into serious problems, affecting the construction progress and even triggering safety accidents.
[0004] On the other hand, it is difficult to accurately grasp the usage of construction materials solely through manual statistics, and situations such as material waste or insufficient supply are likely to occur, resulting in increased costs and project delays.
[0005] Furthermore, for the evaluation of the standardization of construction workers' operation behaviors, manual judgment is highly subjective and inefficient, and potential safety hazards caused by non-standard operations cannot be detected in a timely manner.
[0006] In addition, due to the complex and changeable construction environment, such as the impact of factors like noise and dust on construction, it is difficult for humans to comprehensively and accurately evaluate.
[0007] Chinese Patent No. CN202410082553.X discloses an anomaly recognition method and system for construction based on machine vision, but this invention fails to correct independent data under specific conditions (such as when the overall data has exceeded a reasonable range), and it is unable to capture anomaly trends.
[0008] In summary, the traditional construction management method lacks efficiency, accuracy, and comprehensiveness in the recognition of construction information anomalies, and there is an urgent need for a new technical solution for intelligent construction information anomaly recognition to improve the construction management level and ensure the safety, efficiency, and quality of construction.

[0043] The information collection step is configured to collect multi-source data related to construction information; wherein, the multi-source data at least includes construction equipment operation data, construction material usage data, construction personnel operation behavior data, and construction environment data;

[0056] It should be noted that this embodiment uses existing material management technologies to statistically collect and supervise the usage situation of construction materials.
[0057] Through the above, the present embodiment uses the device data collection sub-step to achieve the collection of material data of construction information, providing a data basis for the early warning of abnormal construction information identification.
[0058] Specifically, the construction information anomaly recognition model is trained based on historical construction information anomaly records and in combination with machine learning techniques;
[0059] The construction information anomaly recognition model stores construction information anomaly features corresponding to multi-source data, and this construction information anomaly feature is used for the recognition of construction information anomalies in multi-source data;
[0060] The construction information anomaly recognition model also stores a construction information anomaly score calculation sub-model for calculating the construction information anomaly score and a construction information anomaly high-risk link capture sub-model for capturing high-risk links of construction information anomalies;
[0061] The construction information anomaly score calculation sub-model evaluates the comparison situation between multi-source data and construction information anomaly features at a time node based on a time series, and calculates the construction information anomaly score;
[0062] The construction information anomaly high-risk link capture sub-model continuously evaluates the comparison situation between multi-source data and construction information anomaly features under this time series based on the time series, and combines the construction information anomaly score to capture high-risk links of construction information anomalies.
[0063] It should be noted that the present embodiment uses existing machine learning techniques to implement the construction of the construction information anomaly recognition model, the construction information anomaly score calculation sub-model, and the construction information anomaly high-risk link capture sub-model. Exemplarily, such as a deep learning model. The construction information anomaly features in the present embodiment are the abnormal features of construction information known to those skilled in the art. Exemplarily, such as abnormal equipment operation, abnormal material use, and abnormal personnel behavior (such as violent behavior, etc.), and the construction information anomaly features in the present embodiment can be obtained based on an open-source construction information feature database, and the present embodiment does not limit this here.
[0064] Through the above, the present embodiment realizes the early warning of construction information anomaly recognition in two dimensions of the whole and the individual based on the construction information anomaly score calculation sub-model and the construction information anomaly high-risk link capture sub-model, thereby realizing the supervision of the overall construction information anomaly of the construction site and the continuous monitoring of the individual construction information, providing a data basis and technical guarantee for the early warning of construction information anomalies.
[0065] Specifically, the operation of the construction information anomaly score calculation sub-model includes the following steps:
[0066] A1: Obtain multi-source data within a construction site at a time node of a time series;
[0067] A2: Extract features from the multi-source data obtained in A1 to obtain corresponding real-time data features;
[0068] A3: Compare the similarity between the real-time data features and the abnormal features of construction information, and calculate the abnormal score of construction information based on the result of the similarity comparison.
[0069] It can be understood that in an actual construction site, most construction information is not generated in a separate form, and the occurrence of abnormal construction information is not without precursors. The purpose of designing the sub-model for calculating the abnormal score of construction information in this embodiment is to comprehensively evaluate the situation of the overall multi-source data of a construction site at a time node of a time series through the index of the abnormal score of construction information, and to judge whether the overall situation is likely to lead to the occurrence of abnormal construction information, that is, to judge whether there are precursors to the occurrence of abnormal construction information.
[0070] Specifically, the calculation of the abnormal score of construction information is specifically as follows:
[0071] Count the number of real-time data features, compare the real-time data features with the abnormal features of construction information respectively, and calculate the abnormal score of construction information based on the obtained similarity, the number of real-time data features and this similarity.
[0072] As a preferred implementation manner of this embodiment, the abnormal score of construction information is calculated using the formula for calculating the abnormal score of construction information. Among them, the formula for calculating the abnormal score of construction information is specifically as follows:
[0073]
[0074] Among them, m is the number of real-time data features, SR (i,τ) is the similarity between the real-time data feature i and the corresponding abnormal feature τ of construction information, VS total is the calculated abnormal score of construction information, and this embodiment uses any existing similarity analysis method to achieve the acquisition of SR (i,τ) The abnormal score threshold of construction information in this embodiment is an empirical value set based on the common knowledge known to those skilled in the art. When the calculated abnormal score of construction information is greater than or equal to the abnormal score threshold of construction information, it is determined that the overall data situation is likely to lead to the occurrence of abnormal construction information, that is, there are precursors to the occurrence of abnormal construction information.
[0075] Specifically, the operation of the sub-model for capturing high-risk links of abnormal construction information includes the following steps:
[0076] B1: Continuously obtain multi-source data based on the time series;
[0077] B2: Extract features from the multi-source data obtained by B1 to obtain corresponding continuous data features;
[0078] B3: Based on the time series, compare the similarity between the continuous data features and the abnormal construction information features to obtain the corresponding relationship between the similarity and the time series. Based on this corresponding relationship, judge the change trend of the similarity. When the change trend of the similarity does not meet the preset change threshold, capture the construction link corresponding to the change trend of the similarity and define it as the high-risk link of abnormal construction information.
[0079] Specifically, the corresponding relationship between the similarity and the time series is specifically:
[0080] Calculate the integral of the similarity between the continuous data features and the abnormal construction information features during the supervision period, and calculate the maximum and minimum values of this integral within the supervision duration. Based on the maximum value and the minimum value, calculate the corresponding relationship between the similarity and the time series.
[0081] It can be understood that in the actual construction process, the generation of abnormal construction information is a process, and based on the analysis of historical abnormal construction information, during the generation process of abnormal construction information, there are fluctuations (that is, the similarity values between the characteristics of individual data and the abnormal construction information characteristics fluctuate). The trend corresponding to this fluctuation reflects that there may be problems in the construction, and further reflects the precursor before the occurrence of abnormal construction information. Therefore, in this embodiment, a sub-model for capturing high-risk links of abnormal construction information is designed to realize continuous analysis of individual data in the construction, so as to capture this fluctuation (that is, capture the high-risk links of abnormal construction information).
[0082] As a preferred implementation manner of this embodiment, use the formula for capturing high-risk links of abnormal construction information to capture high-risk links of abnormal construction information. Among them, the formula for capturing high-risk links of abnormal construction information is specifically:
[0083]
[0084] Among them, t n ∈T and T = [t1, t2, t3,... t n , T is the preset supervision duration, divide T into n equal time periods, t n is the nth time period within T, represents the integral of the similarity between the real-time data feature i and the corresponding abnormal construction information feature τ in the nth time period within T, max is the maximum value calculation operator, min is the minimum value calculation operator, VS single_iFor the fluctuation of the calculated real-time data feature i, when the fluctuation is greater than or equal to the change threshold (the change threshold is an empirical value set based on the common knowledge known to those skilled in the art), it is determined that there is a fluctuation in the real-time data feature i, that is, there is a precursor before the occurrence of abnormal construction information, and the real-time data feature i is defined as a high-risk link for abnormal construction information.
[0085] Specifically, the operation of the high-risk link capture sub-model for abnormal construction information further includes the following steps:
[0086] When the abnormal construction information score does not meet the abnormal construction information score threshold, update B3 to the following steps:
[0087] B31: Based on the time series, compare the similarity between the continuous data feature and the abnormal construction information feature to obtain the corresponding relationship between the similarity and the time series; obtain the abnormal construction information score, and correct the corresponding relationship between the similarity and the time series based on the abnormal construction information score to obtain the corrected corresponding relationship. Based on the corrected corresponding relationship, judge the change trend of the similarity. When the change trend of the similarity does not meet the preset change threshold, capture the construction link corresponding to the change trend of the similarity and define it as a high-risk link for abnormal construction information.
[0088] Based on B3, it can be understood that compared with the construction sites that meet the abnormal construction information score threshold, the probability of abnormal construction information occurring at the construction sites that do not meet the abnormal construction information score threshold will increase significantly. Therefore, this embodiment designs B31 to capture the high-risk link for abnormal construction information that comprehensively considers the abnormal construction information score. Specifically, the high-risk link for abnormal construction information is captured urgently using the emergency high-risk link capture formula for abnormal construction information. Among them, the emergency high-risk link capture formula for abnormal construction information is specifically:
[0089]
[0090] Among them, VS total_τ is the aforementioned abnormal construction information score threshold. Based on the emergency high-risk link capture formula for abnormal construction information, when the abnormal construction information score does not meet the abnormal construction information score threshold, use the operator to amplify VS in B3 single_i , calculate to obtain VS single_i_E . When the fluctuation is greater than or equal to the change threshold, it is determined that there is a fluctuation in the real-time data feature i, that is, there is a precursor before the occurrence of abnormal construction information, and the real-time data feature i is defined as a high-risk link for abnormal construction information, so as to realize the capture of the high-risk link for abnormal construction information that comprehensively considers the abnormal construction information score.
[0091] Specifically, the countermeasures at least include the construction adjustment plan, the emergency resource allocation process, and the evacuation plan for the on-site construction personnel.
[0092] It should be noted that based on the historical processing method of abnormal construction information in this embodiment, corresponding countermeasures are refined, and a corresponding early warning plan is designed based on the actual construction situation, so as to output corresponding response methods for different situations of abnormal construction information.
[0093] Through the above, this embodiment realizes the targeted processing of abnormal construction information, effectively reduces the possibility of occurrence of high-risk links of abnormal construction information in the construction site, improves the construction management level, and ensures the safety, efficiency and quality of construction.
[0094] In summary, the intelligent construction information anomaly recognition method of this embodiment uses the information acquisition module to realize the acquisition of multi-source data related to construction information, uses the evaluation module to realize the information anomaly recognition in both the overall and individual dimensions, and corrects the recognition of individual construction links by using the overall information anomaly. The early warning module realizes the visual display of the evaluation results of the evaluation module, and provides a comprehensive response method for dealing with abnormal construction information, so as to realize the comprehensive calculation of the abnormal construction information score of the construction site to overall grasp the situation of abnormal construction information in the site, and at the same time can accurately capture the high-risk links of abnormal construction information to clarify the specific construction links of individual anomalies, which helps the construction administrator to know the potential risks in advance, take corresponding measures, effectively reduce the possibility of occurrence of high-risk links of abnormal construction information in the construction site, improve the construction management level, and ensure the safety, efficiency and quality of construction.
