Abstract
Description
Technical Field
[0001] This disclosure relates to the field of industrial waste gas leak detection and repair (LDAR) technology, and in particular to a system for verifying the authenticity of LDAR detection operations based on spatiotemporal fingerprinting. Background Technology
[0002] Leak Detection and Repair (LDAR) is a core tool for controlling fugitive emissions of volatile organic compounds (VOCs) in the petrochemical and chemical industries. However, the current regulatory model has long faced the dilemma of "difficulty in ensuring data authenticity and difficulty in identifying fraud." Traditional LDAR data auditing mainly relies on manual spot checks. Faced with millions of sealing point detection records from enterprises, the coverage rate is often less than 1%, like "finding a needle in a haystack." More seriously, with the "high-tech" nature of fraud methods, third-party testing agencies often use customized software to generate "perfect fake data" that conforms to static rules (such as fixed detection intervals and reasonable numerical ranges). Individually, these data entries appear flawless and can pass simple threshold checks. Existing technology lacks a three-dimensional auditing mechanism that combines physical kinematic constraints (such as personnel movement speed and spatial topology) with historical behavioral baselines, making it impossible to identify deep-seated and concealed fraudulent behaviors such as "teleportation detection," "through-wall detection," and "data cloning," resulting in difficulties in effectively curbing data fraud.
[0003] In related technologies, single data entries are often verified using static rules such as fixed detection time and reasonable numerical range. However, these technologies are difficult to identify hidden fraudulent behaviors that involve overall logical fraud, making it difficult to ensure data authenticity and identify fraud, which in turn leads to a low fraud detection rate and high regulatory costs.

Finally, it performs similarity detection on the current leak detection data and historical leak detection data, yielding a first similarity detection result. Finally, a multi-factor nonlinear fusion process is applied to the spatial, temporal, and first similarity detection results to obtain the operational detection result for the current leak detection data. This system integrates logical verification from three independent dimensions—time, space, and data similarity—and employs a multi-factor nonlinear fusion model for comprehensive scoring. The dimensions complement and cross-validate each other, ensuring that even if a fraudster evades detection in a single dimension, the overall score effectively identifies anomalies, significantly improving the detection rate and accuracy of fraudulent activities.

In a specific embodiment, the target sealing point can be a sealing location to prevent leakage. Optionally, the target sealing point can include at least one of the following locations: valve, flange, pump, etc. Specifically, the detection of the target sealing point and adjacent sealing points can be a leak detection of the target sealing point and adjacent sealing points.

By fitting multiple historical detection intervals, the historical detection interval features are obtained.
[0042] In one specific embodiment, the second historical leakage detection data can be the historical leakage detection data corresponding to adjacent sealing points, and the first historical detection time set can be the historical detection time set corresponding to the target sealing point. Specifically, the first historical detection time set can include multiple historical detection times corresponding to the target sealing point, and the second historical detection time set can be the historical detection time set corresponding to adjacent sealing points. Specifically, the second historical detection time set can include multiple historical detection times corresponding to adjacent sealing points.
[0043] In a specific embodiment, multiple historical detection intervals can be multiple historical detection time intervals between the target sealing point and adjacent sealing points in multiple preset detection cycles. Specifically, the historical detection interval characteristics can include the mean and standard deviation of the historical time detection intervals between the target sealing point and adjacent sealing points. The mean and standard deviation of the historical time detection intervals are calculated by performing extreme value removal and normal distribution fitting processing on multiple historical time detection intervals.
[0044] In the above embodiments, by using multiple historical detection intervals as fitting features, the system closely matches the working habits of the site and the testing personnel, significantly reducing misjudgments. Furthermore, by utilizing statistical fitting, the system weakens single-instantaneous interference, thereby improving the stability of the time verification basis.
[0045] In a specific embodiment, a preset detection confidence interval can be set by the mean and standard deviation of the historical time detection interval in the historical time detection interval feature. Specifically, the difference between the mean and the standard deviation of the historical time detection interval can be used as the lower limit of the preset detection confidence interval, and the sum of the mean and the standard deviation of the historical time detection interval can be used as the upper limit of the preset detection confidence interval.
[0046] In one specific embodiment, for example, the average of the historical time detection intervals is used as... The standard deviation of the historical time detection interval is For example, the preset detection confidence interval can be ( - , + ).
[0047] In the above embodiments, by setting a reasonable confidence interval based on the historical detection interval characteristics between the target sealing point and adjacent sealing points, the detection cycle of each point can be automatically identified based on historical data, thereby reducing the false judgment rate.
[0048] In step S203, based on the detection time in the first current leak detection data and the detection time in the second current leak detection data, a first detection interval between the target sealing point and the adjacent sealing point is determined; In one specific embodiment, the first detection interval can be the current detection time interval between the target sealing point and the adjacent sealing point. Specifically, the first detection interval can be obtained by taking the absolute value of the detection time in the first current leakage detection data and the detection time in the second current leakage detection data.

Specifically, the first-time detection result can be obtained by comparing the first detection interval with the preset detection confidence interval. Optionally, the first-time detection result can be obtained by the ratio of the difference between the first detection interval and the mean of the historical time detection interval to the standard deviation of the historical time detection interval.

The standard deviation of the historical time detection interval between the target sealing point and adjacent sealing points can be... The preset detection confidence interval can be ( - , + Accordingly, the first-time test results can be obtained by It was stated that the test results were available immediately. If the value is greater than 1, it is determined that there is an anomaly in the current leakage detection data in the time detection dimension, and the detection result is detected immediately. When the value is less than or equal to 1, it is determined that there is no anomaly in the current leakage detection data in the time detection dimension.
[0051] In step S207, based on the first historical detection time set in the first historical leakage detection data, time detection is performed on the detection time in the first current leakage detection data to obtain the second time detection result; In a specific embodiment, the first historical detection time set can be a set of historical detection times corresponding to the target sealing point. The first historical detection time set can include multiple historical detection times that characterize the detection time interval of the target sealing point as having historical periodicity. The second time detection result can characterize whether the first current leakage detection data is abnormal in the time detection dimension. Specifically, the second time detection result can characterize whether the first current leakage detection data and the first historical leakage detection data are consistent in the time detection dimension.
[0052] In an optional embodiment, the above-mentioned time detection based on the first historical detection time set in the first historical leakage detection data to obtain the second time detection result may include: Determine a second detection interval between the detection time in the first current leak detection data and multiple historical detection times in the first historical detection time set; The second detection interval is compared with the preset detection time interval to obtain the second time detection result.
[0053] In one specific embodiment, the second detection interval may be the detection interval between the detection time in the first current leakage detection data and multiple historical detection times in the first historical detection time set.
[0054] In a specific embodiment, the second detection interval can be compared with the preset detection time interval. If the second detection interval is the preset detection time interval, a second time detection result is obtained, which indicates that the first current leakage detection data does not have abnormal detection in the time detection dimension. If the second detection interval is not the preset detection time interval, a second time detection result is obtained, which indicates that the first current leakage detection data has abnormal detection in the time detection dimension.
[0055] In the above embodiments, by using dynamic historical time fingerprints with historical periodicity as a benchmark and comparing them with preset detection time intervals, time dimension fraud can be identified, false judgments can be reduced, and the computation is lightweight, ensuring accurate and efficient time detection.
[0056] In step S209, the first detection interval and the moving time threshold are compared to obtain the first spatial detection result of the first current leakage detection data; In a specific embodiment, the movement time threshold can characterize the shortest time required for an adjacent sealing point to travel to the target sealing point for detection. The first spatial detection result can be the abnormal detection result of the first current leakage detection data in the spatial detection dimension. Specifically, the first spatial detection result can be obtained by comparing the first detection interval and the movement time threshold. Optionally, the first spatial detection result can be obtained by the ratio of the first detection interval to the movement time threshold.

When the value is less than or equal to 1, it is determined that there is no abnormality in the current leakage detection data in the first spatial detection dimension.
[0058] In step S2011, based on the target historical detection location set in the first historical leakage detection data, spatial detection is performed on the detection location in the first current leakage detection data to obtain the second spatial detection result.
[0059] In a specific embodiment, the target historical detection location set can be a set of historical detection locations corresponding to the target sealing point. The target historical detection location set can include multiple historical detection locations that characterize the spatial location of the target sealing point as having historical consistency. The second spatial detection result can characterize whether the first current leakage detection data is abnormal in the spatial detection dimension. Specifically, the second spatial detection result can characterize whether the first current leakage detection data and the first historical leakage detection data are consistent in the spatial detection dimension.
[0060] In an optional embodiment, the above-mentioned spatial detection of the detection locations in the first current leakage detection data based on the target historical detection location set in the first historical leakage detection data to obtain the second spatial detection result may include: Determine the second location distance between the detection location in the first current leak detection data and multiple historical detection locations in the target historical detection location set; The second spatial detection result is obtained based on the second location distance and the preset distance threshold.
[0061] In one specific embodiment, the second average distance can be the distance between the detection location in the first current leak detection data and multiple historical detection locations in the target historical detection location set.
[0062] In a specific embodiment, the average distance between the detection location and multiple historical detection locations in the first current leak detection data can be calculated based on the second location distance. Specifically, if the average distance between the detection location and multiple historical detection locations in the first current leak detection data reaches a preset distance threshold, a second spatial detection result is obtained that indicates that the first current leak detection data has abnormal detection in the spatial detection dimension. If the average distance between the detection location and multiple historical detection locations in the first current leak detection data does not reach the preset distance threshold, a second spatial detection result is obtained that indicates that the first current leak detection data does not have abnormal detection in the spatial detection dimension.
[0063] In the above embodiments, by using a dynamic historical spatial fingerprint with historical consistency as a benchmark and combining it with a preset distance threshold for judgment, wall penetration detection or other anomalies can be performed, while simplifying the calculation and ensuring accurate and efficient spatial detection.

The leak detection dataset can include at least one of the following: sealing point identifier, spatial location coordinates, detection timestamp, detection personnel ID, detection value, etc. Optionally, multiple current leak detection datasets can include target leak detection datasets. The multiple current leak detection datasets can be obtained by classifying the first current leak detection data and multiple historical leak detection data. This can be achieved by generating multiple hash signatures from multiple historical leak detection data using the MinHash algorithm, and then classifying similar historical leak detection data using the LSH algorithm.
[0067] In a specific embodiment, the first similarity estimation result can characterize the similarity between the first current leak detection data and the leak detection data in the target leak detection dataset other than the first current leak detection data. Specifically, the first similarity estimation result can be the similarity Jaccard. The closer the similarity Jaccard is to 1, the higher the similarity between any two leak detection data.
[0068] In a specific embodiment, for example, the first similarity estimation result can be similarity J, and the first similarity detection result can be determined by... This indicates that it can be detected in the first similarity detection result. When the preset similarity threshold is reached, it is determined that there is an anomaly in the current leakage detection data in the first similarity detection dimension.

If either the second spatial detection result or the second temporal detection result indicates that the first current leakage detection data has abnormal detection, an auxiliary verification result indicating that the first current leakage detection data does not need auxiliary verification is obtained. Optionally, if the auxiliary verification result indicates that the first current leakage detection data does not need auxiliary verification, the operation detection result of the first current leakage detection data is obtained based on the second spatial detection result and the second temporal detection result.

[0078] In an optional embodiment, the first historical leakage detection data includes a first historical detection time set, and the above method may further include: Obtain multiple historical detection times corresponding to the target sealing point; Determine the detection time interval between two adjacent historical detection times from among multiple historical detection times; When the detection time interval is a preset detection time interval, a first historical detection time set is obtained based on multiple historical detection times.

[0085] In a specific embodiment, the second similarity estimation result can characterize the similarity between any two leak detection data in the leak detection data. The second similarity estimation result can include the current similarity estimation result and the historical similarity estimation result. The current similarity estimation result can characterize the similarity between the current leak detection data corresponding to each of the multiple detection objects, and the historical similarity estimation result can characterize the similarity between multiple historical leak detection data corresponding to each detection object. Optionally, the above-mentioned similarity detection of multiple leak detection data corresponding to multiple detection objects to obtain the second similarity estimation result corresponding to each of the multiple leak detection data can include: performing similarity detection on the current leak detection data corresponding to the multiple detection objects to obtain the current similarity estimation result corresponding to the current leak detection data; and performing similarity detection on multiple historical leak detection data corresponding to each of the multiple detection objects to obtain the historical similarity estimation result corresponding to each detection object.
[0086] In a specific embodiment, the second similarity detection result can characterize whether there are any anomalies in the similarity detection dimension of the leakage detection data corresponding to each detection object. Specifically, the second similarity detection result can include historical similarity detection results and current similarity detection results. The current similarity detection result can characterize whether there are any anomalies in the current leakage detection data corresponding to each detection object in the similarity detection dimension, and the historical similarity detection result can characterize whether there are any anomalies in the similarity detection dimension of multiple historical leakage detection data corresponding to each detection object. Optionally, the second similarity estimation result can be a Jaccard similarity estimate. If the Jaccard similarity estimate exceeds a preset similarity threshold, the leakage detection data is suspected of being falsified. If the number and / or proportion of suspected falsified leakage detection data pairs exceed a preset aggregation threshold, a second similarity detection result characterizing the leakage detection data having anomaly detection in the similarity detection dimension can be obtained.
[0087] In a specific embodiment, the second similarity estimation result can be the current similarity estimation result, which can be the Jaccard similarity estimate between the current leakage detection data corresponding to multiple detection objects. The above-mentioned determination of the second similarity detection result corresponding to each of the multiple leakage detection data based on the second similarity estimation result can include: for the current leakage detection data corresponding to multiple detection objects, if the Jaccard similarity estimate exceeds a preset similarity threshold, it is determined that the current leakage detection data pair is suspected of being fraudulent; if the number and / or proportion of the current leakage detection data pairs suspected of being fraudulent exceeds a preset aggregation threshold, a current similarity detection result can be obtained that characterizes the current leakage detection data corresponding to the detection object as having abnormal detection in the similarity detection dimension.

The preset detection confidence interval represents a reasonable range of time detection intervals between the target sealing point and adjacent sealing points; the moving time threshold represents the shortest time required for adjacent sealing points to travel to the target sealing point for detection. Based on the detection time in the first current leakage detection data and the detection time in the second current leakage detection data, a first detection interval between the target sealing point and adjacent sealing points is determined. Based on the first detection interval and the preset detection confidence interval, time detection is performed on the first current leakage detection data to obtain a first time detection result of the first current leakage detection data. The first detection interval and the moving time threshold are compared to obtain a first spatial detection result of the first current leakage detection data. Similarity detection is performed on the first current leakage detection data and the first historical leakage detection data to obtain a first similarity detection result of the first current leakage detection data. Multi-factor nonlinear fusion processing is performed on the spatial detection result, the time detection result, and the first similarity detection result to obtain the operational detection result of the first current leakage detection data. It can integrate logical verification of three independent dimensions: time, space, and data similarity, and use a multi-factor nonlinear fusion model for comprehensive scoring. Each dimension complements and cross-verifies each other. Even if the fraudster evades the detection of a single dimension, the overall score can still effectively identify anomalies, significantly improving the detection rate and accuracy of fraudulent behavior.
