Description

Technical Field

[0001] The present invention belongs to the technical field of data quality control, and specifically is a monitoring data quality control method based on deep learning and self-built rules. Background Art

[0002] Natural resource monitoring data refers to information collected through long-term, systematic, and dynamic observation and recording of the quantity, quality, distribution, utilization, and ecological environment of natural resources, such as land, water, forests, minerals, and oceans, using technologies such as remote sensing, geographic information systems (GIS), ground surveys, and sensor networks. These data serve as a crucial foundation for national and local natural resource management, environmental protection, planning and decision-making, and disaster early warning. To ensure the reliability, accuracy, and timeliness of these data, rigorous quality control is essential. This includes developing unified data collection standards and specifications, implementing advanced calibration and verification techniques, establishing multi-source data fusion mechanisms, conducting regular field verification and sampling inspections, and developing a data quality assessment system. Quality control permeates the entire data collection, processing, analysis, and application process, aiming to promptly identify and correct deviations, ensure that monitoring results accurately reflect the current status and changing trends of natural resources, and provide solid data support for sustainable development and the development of an ecological civilization. Quality control of natural resource monitoring data is a crucial component of natural resource monitoring.

[0003] However, traditional manual quality control methods are no longer able to meet the needs. The existing technology has the following problems: 1. Fixed quality inspection rules lack flexibility. Data quality requirements may vary in different monitoring scenarios. 2. Lack of comparison between data from different devices. 3. Seasonality and cyclicality of time series. Natural resource monitoring data often exhibit significant seasonal and cyclical characteristics. 4. Existing simple interpolation methods (such as linear interpolation) assume that data changes linearly within the missing interval when processing missing data, but in reality, natural resource data is often nonlinear. For example, in an atmospheric pollution event, the change in pollutant concentration may be exponential, and linear interpolation will result in a large deviation between the corrected data and the actual data. Summary of the Invention

[0006] d) Use deep learning modules to perform data prediction and repair based on deep learning models; e) Generate quality inspection report.

[0007] In a preferred embodiment, in step c), the quality inspection rule establishment and inspection method for abnormal values, limit values, and mutation values ​​include: a) Calculate outliers (Z-score method), upper and lower limits (percentile threshold method), data change rate, etc. to assist in determining quality inspection rules; b) Set quality inspection rules for abnormal values, limit values, and mutation values; c) determining whether the data point exceeds the threshold range; d) Mark or delete data points that exceed the threshold.

[0008] In a preferred embodiment, in step c), Outlier detection is determined based on the specific device requirements and expert experience. Outliers are determined using the Z-score method, as follows.

[0009] .

[0010] in, is the data mean, σ is the standard deviation, To monitor the data value; the “3σ” principle is used to test the data. When the Z-score is greater than the set threshold (3.0), x is determined to be an outlier.

[0011] The limit value check uses the percentile threshold method to determine the upper and lower limits of the limit value. The principle is: after removing outliers from the original data, add or subtract 1 standard deviation based on the 99.9% (upper limit) or 0.1% (lower limit) profile to form dynamic upper and lower limit thresholds.

[0012] The mutation value check determines the rules by calculating the rate of change between adjacent moments. The principle is as follows.

[0013] .

[0014] in It is the monitoring data at time t. When the change rate exceeds the set maximum allowable change rate, it is determined to be a mutation value.

[0015] Multi-device consistency comparison check: Users can ensure the consistency of data with internal logical relationships between different devices by defining the maximum difference allowed between different data on different devices. This is important for discovering equipment failures, data transmission errors, or local anomalies of natural resources.

[0016] In a preferred embodiment, in step c), the method for establishing and checking time continuity quality inspection rules includes: a) Set the monitoring frequency of the data according to the equipment, in minutes; b) Determine whether there are missing values ​​in the time series of data points; c) Mark the locations of missing data or simply interpolate to fill them.

Different types of monitoring data often have different temporal characteristics. Traditional simple interpolation and mean / median replacement methods fail to reflect the true nature of the data. The deep learning module uses an LSTM layer to construct a time series prediction model. LSTM is an algorithm that improves the recurrent neural network (RNN) model. It incorporates input gates, forget gates, output gates, and storage units into the RNN network structure, thereby improving the performance of RNNs. This method effectively overcomes short-term dependencies in RNNs, enabling more efficient information extraction from long time series data. Furthermore, the LSTM model offers the advantage of dynamically processing historical data, enabling storage and memorization of historical data. Compared to traditional neural network models, LSTM maintains the advantages of RNNs in parameter transfer. Its hidden layer also enables parameter sharing through inter-node connections and can continuously calculate and update based on input information. Figure 9 is the network structure diagram of LSTM, where For the input gate, For hidden doors, is the output gate, and the mathematical expressions of the three gates are as follows.

[0021]

[0023]

[0024] in Indicates the updated value of the unit state, and finally the output gate and cell status Calculate the output of the next layer .

[0025] .

[0026] In a preferred embodiment, in step d), the user learns a large amount of historical data by setting indicators such as sequence length, prediction steps, moving average window size, outlier threshold, and number of training rounds, and obtains the characteristics of the monitoring data changing over time, so as to accurately simulate missing data or predict future data. The present invention also provides RSME and Pearson correlation coefficient indicators to evaluate the accuracy of deep learning predicted data, and the principle is as follows.

[0027]

[0028] Among them, is the actual value, is the predicted value, and n is the number of observed values; the closer the value of RMSE is to 0, the higher the prediction accuracy.

[0029]

[0030] Among them, and are the i-th observed values of the two variables respectively, and are the means of the two variables respectively, n is the number of observed values, and r is the Pearson correlation coefficient. The value range of r is: [-1, 1]; when 0 < r ≤ 1, there is a positive correlation between the independent variable and the dependent variable; when -1 < r ≤ 0, there is a negative correlation between the independent variable and the dependent variable; when |r| ≥ 0.8, it is considered highly correlated; when 0.5 ≤ |r| < 0.8, it is considered moderately correlated; when 0.3 ≤ |r| < 0.5, it is considered weakly correlated; when |r| ≤ 0.3, the correlation between the independent variable and the dependent variable is considered very weak or irrelevant.

[0031] In a preferred embodiment, in step e), the content of the quality inspection report includes: a) Statistical information of basic data; b) Summary of quality inspection results; c) Export of quality inspection report.

[0032] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are: 1. In the present invention, by combining flexible rule configuration with advanced time series analysis technology, the reliability and practicality of natural resource monitoring data are significantly improved. First, the method supports users to customize multi-dimensional quality inspection rules according to actual scenario requirements, including rules such as outliers, boundary values, mutation values, time continuity and logic, breaking through the limitations of traditional fixed rules. By introducing time logic checks, the system can effectively identify anomalies in the data caused by seasonal or cyclical changes, such as the reasonable fluctuation range of vegetation index in different seasons, thereby more accurately capturing the temporal characteristics of the data. In addition, the multi-device consistency comparison function realizes cross-device data cross-validation, which can promptly detect equipment failures or local environmental anomalies, and ensure the logical consistency and overall credibility of multi-source data.

[0033] 2. In the present invention, a deep learning model is applied to solve the problem of data repair and prediction. By utilizing the dynamic modeling ability of the LSTM network for long time series data, the system can learn the complex nonlinear characteristics of historical data, such as the exponential change trend of pollutant concentration, which significantly improves the accuracy of missing data repair and future predictions. Compared with traditional linear interpolation or mean replacement methods, the deep learning model can better fit the real data distribution and reduce the repair error. At the same time, the system supports quantitative evaluation of prediction effects through indicators such as RMSE and Pearson correlation coefficient, providing a scientific verification basis for data quality.
