DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments. It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other.
[0022] The following detailed descriptions are all exemplary descriptions, aiming to provide a further detailed description of the present invention. Unless otherwise specified, all technical terms used in the present invention have the same meaning as commonly understood by those of ordinary skill in the art to which this application belongs. The terms used in the present invention are only for the purpose of describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention.
[0023] Embodiment 1 As Figure 1 shown, the present invention provides a power outage risk identification system based on data analysis, including a data acquisition module, a communication module, and an analysis module; The data acquisition module is used to obtain the monitoring data of power equipment; The data acquisition module includes an acquisition unit, a data filtering unit, and a transmission unit; the acquisition unit is used to obtain the monitoring data of power equipment; the data filtering unit is used to filter the monitoring data to obtain the filtered monitoring data, including: calculating the sampling frequency of the monitoring data according to the acquisition time of the monitoring data, determining the filtering algorithm based on the sampling frequency, and filtering the monitoring data based on the filtering algorithm to obtain the filtered monitoring data; the transmission unit is used to transmit the filtered monitoring data to the communication module; the communication module is used to transmit the monitoring data to the analysis module; The analysis module is used to identify the power outage risk of power equipment based on the monitoring data and obtain the identification result.
[0024] The above power outage risk identification system provided by the present invention can adaptively select a filtering algorithm based on the sampling frequency of the monitoring data of power equipment to filter the latest obtained monitoring data, so that the filtering algorithm can adapt to the sampling frequency of the monitoring data. In this way, while ensuring the filtering effect, more information can be retained for the data after filtering, enabling the data after filtering to more truly reflect the change trend of the real data, thereby improving the accuracy of the result of identifying the power outage risk of power equipment.
[0025] Preferably, the monitoring data includes the amplitude of the power equipment, the temperature on the surface of the power equipment, and the operating voltage of the power equipment.
[0026] Specifically, the amplitude of the power equipment can be obtained by a vibration sensor arranged inside the power equipment. The temperature on the surface of the power equipment can be obtained by a temperature sensor arranged on the surface of the power equipment. The operating voltage of the power equipment can be obtained by a voltage sensor arranged on the power supply line of the power equipment.
[0027] Preferably, calculating the sampling frequency of the monitoring data according to the acquisition time of the monitoring data includes: Let A represent the type of monitoring data, and use to represent the acquisition time of the latest obtained A-type monitoring data by the acquisition unit. Then the calculation formula for the sampling frequency of A-type monitoring data is:
[0028] where represents the sampling frequency of A-type monitoring data, and N represents the time interval Within it, the total number of monitoring data of type A acquired by the acquisition unit, and T is the preset time length.
[0029] Specifically, by obtaining the quantity of monitoring data of the same type acquired within a fixed time length, the sampling frequency of this type of monitoring data can be updated in real time. Thus, when the sampling frequency of the monitoring data changes, there is no need to manually update the sampling frequency, and the real-time performance of the sampling frequency can be made stronger.
[0030] Preferably, the preset time length is 60 seconds.
[0031] In addition, the preset time length can also be 120 seconds, 240 seconds, etc.
[0032] Preferably, determining the filtering algorithm based on the sampling frequency includes: Judging whether the sampling frequency is greater than the preset frequency threshold. If so, the first filtering algorithm is used as the filtering algorithm; if not, the second filtering algorithm is used as the filtering algorithm.
[0033] Specifically, by setting a frequency threshold to determine the filtering algorithm for the monitoring data, the sampling frequency of the monitoring data can be adapted to the filtering algorithm, avoiding excessive delay of the filtered data and being unable to correctly represent the change trend of the monitoring data.
[0034] Preferably, the preset frequency threshold can be 30 times per minute.
[0035] Preferably, the first filtering algorithm includes: For the latest obtained k-th monitoring data of type A , for The formula for filtering is as follows:
[0036] Wherein, represents the (k - 1)-th monitoring data of type A, represents the preset comparison value, represents for The filtered monitoring data of type A obtained after filtering.
[0037] The above filtering algorithm filters by setting a preset comparison value, and can filter out the mutated data when the monitoring data mutates due to the failure of the acquisition unit, so as to effectively retain the correct data change trend.
[0038] Preferably, the preset comparison value is one-fourth of the upper limit value of the value range of the monitoring data of type A.
[0039] For example, if the value range of the operating voltage is [10, 100], the upper limit value is 100, and the preset comparison value is 25.
[0040] If the filtering algorithm is the second filtering algorithm, the monitoring data is filtered in the following manner: Preferably, the second filtering algorithm includes: For the most recently obtained kth piece of monitoring data of type A , the process of filtering is as follows: Store the first D pieces of monitoring data of type A with the acquisition time closest to the acquisition time of into the set AU; Filter using the following formula:
[0041] where represents the filtered monitoring data of type A obtained after filtering , represents the time length between the acquisition times of represents the first weight, represents the second weight, and i is the monitoring data of type A in AU.
[0042] In the second filtering algorithm proposed in the embodiments of the present invention, the filtering weight of i is determined respectively from the time length between the acquisition times of two pieces of monitoring data i and with different acquisition times and the numerical difference between i and . Thus, when the time length between the acquisition times of i and is smaller and the numerical difference between i and is smaller, the weight of i is made larger. When the time length between the acquisition times of i and is larger and the numerical difference between i and is larger, the weight of i is made smaller. The adaptive change of the weight of i is realized, such that the greater the influence on the change of , the greater the weight of the data with greater reference value, and the smaller the influence on the change of , the smaller the weight of the data with smaller reference value, effectively improving the accuracy of the final filtering result.
[0043] Specifically, the first weight is 0.6 and the second weight is 0.4.
[0044] Preferably, the communication module includes at least one of a 4G communication device, a 5G communication device, and a satellite communication device.
[0045] Specifically, the communication module can be installed on the power equipment to be monitored.
[0046] Preferably, the analysis module includes a storage unit and an identification unit; The storage unit is used to store the monitoring data and fault records of the power equipment; The identification unit is used to periodically identify the power outage risk of the power equipment based on the monitoring data and fault records stored in the storage unit, and obtain an identification result.
[0047] Specifically, the storage unit can store historical monitoring data, which is conducive to providing data support for subsequent prediction processes.
[0048] Preferably, identifying the power outage risk of the power equipment based on the monitoring data stored in the storage unit and obtaining an identification result includes: inputting the monitoring data obtained within a preset time interval into a trained prediction model for prediction to obtain an identification result.
[0049] Specifically, the identification result can be a failure probability.
[0050] Specifically, the training process of the prediction model is as follows: 1. Data cleaning Process the missing values, outliers, and duplicate values of the data stored in the storage unit to make the data complete and consistent. For time series data, align or interpolate the timestamps to make the data time step consistent.
[0051] 2. Data annotation Label definition: For the model predicting faults, determine which data represents the "fault" state and which represents the "normal" state. In this solution, clear labels are set for the fault data (e.g., 1 represents fault and 0 represents normal).
[0052] Label generation: Generate labels according to the fault records, and each historical record corresponds to a label value. If the data volume is large, the time window can be used as the basis for label generation. For example, the data in a period of time before the equipment fails is marked as 1.
[0053] 3. Feature extraction Feature extraction: Extract features useful for fault prediction from the original data. The features can be univariate statistical features (such as mean, standard deviation, extreme values, etc.), time series features (such as autoregressive coefficients, trends, periods, etc.), or composite features (such as the ratio between two variables, etc.).
[0054] Feature selection: Screen out important features through methods such as correlation analysis and principal component analysis (PCA) to avoid the impact of feature redundancy on the model performance.
[0055] 4. Data Segmentation Training set and test set: Divide the data into a training set and a test set to ensure that the model can perform well on unseen data. Time series data can be divided in chronological order to avoid future data leakage to the model.
[0056] Cross-validation: To avoid overfitting, cross-validation methods can be used, especially time series cross-validation (such as rolling window cross-validation).
[0057] 5. Model Selection and Training Select a model: In this solution, according to actual needs, common predictive fault models are selected. For example, common predictive fault probability models include logistic regression, support vector machine (SVM), random forest, gradient boosting trees (such as XGBoost), neural networks (such as LSTM, GRU), etc. This solution can select a suitable model according to actual requirements.
[0058] Model training: Perform model training on the training set. For models of time series data (such as LSTM or GRU), the input data is the data of multiple time steps of the sequence, rather than the data of a single time point.
[0059] 6. Model Evaluation Performance evaluation: Use the test set to evaluate the model. Evaluation metrics can include accuracy, recall, precision, F1 score, AUC (area under the ROC curve), etc.
[0060] Probability prediction: In addition to giving a binary classification result of fault or normal, the model can also output the fault probability. By adjusting the probability threshold, the accuracy and recall of the prediction can be balanced.
[0061] 7. Hyperparameter Tuning and Optimization Hyperparameter tuning: Perform hyperparameter tuning through methods such as grid search, random search, or Bayesian optimization to further improve the model performance.
[0062] In the above solution, the filtering algorithm is dynamically selected according to the sampling frequency of the monitoring data, which can ensure the filtering effect while retaining more information and improving the recognition accuracy. The filtered data can more truly reflect the data change trend, improving the accuracy of power outage risk recognition. At the same time, using the prediction model for risk recognition improves the intelligent level of recognition. The present invention effectively solves the problem of signal distortion in the prior art and improves the accuracy and intelligent level of power outage risk recognition through the adaptive filtering technology and intelligent recognition method.
