[0002] As a clean energy, hydrogen energy has gradually become an important direction for global energy transformation. Hydrogen energy processing equipment plays a key role in the energy conversion and storage process, and its safety is directly related to production efficiency and personnel safety. However, due to the high flammability of hydrogen and the complexity of the equipment operating environment, different types of failures may occur during the long-term operation of hydrogen energy processing equipment, such as equipment aging, sensor failure, hydrogen leakage, etc. These failures may lead to serious safety accidents. Therefore, real-time monitoring and fault early warning of hydrogen energy processing equipment have become urgent problems to be solved.

[0033] Embodiment
[0034] The present invention discloses an intelligent safety monitoring and warning method for a hydrogen energy processing device, as Figure 2 shown, including:
[0035] Step 1: Monitor and collect the operation data and hydrogen concentration data of the hydrogen energy processing device;
[0036] Adopt a distributed sensor network, install a variety of sensors on the hydrogen energy processing device body, key components and connecting pipelines, collect the operation data such as the pressure, temperature, vibration frequency and flow rate data of the hydrogen energy processing device and the hydrogen concentration data. At the same time, set the data sampling frequency fs and the number of sampling points N1 of each sensor to ensure that the data has sufficient time series resolution;
[0037] Specific sensor types and installation and deployment locations:
[0038] Install a pressure sensor at the gas storage tank and pipeline interface of the hydrogen energy processing device to detect and obtain the pressure data of the hydrogen energy processing device;
[0039] Install a temperature sensor at the heating unit and cooling system of the hydrogen energy processing device to detect and obtain the temperature data of the hydrogen energy processing device;
[0040] Install a vibration sensor at the hydrogen compressor and pump body of the hydrogen energy processing device to detect and obtain the vibration frequency data of the hydrogen energy processing device;
[0041] Install a flow sensor in the pipeline of the hydrogen energy processing device to detect and obtain the hydrogen flow rate data in the pipeline of the hydrogen energy processing device;
[0042] Install a hydrogen concentration sensor around the hydrogen energy processing device and in the key sealing areas to detect and obtain the hydrogen concentration data of the hydrogen energy processing device.
[0043] After that, the Kalman filter is used to process the operation data of the hydrogen energy processing equipment and the hydrogen concentration data collected by the various sensors, and the state estimation algorithm is used to reduce random noise; for impact data such as vibration frequency, median filtering is used to remove instantaneous impact interference; the operation data of the hydrogen energy processing equipment and the hydrogen concentration data are standardized by Z-score standardization, and Min-Max normalization is used to map the data to between [0, 1]:
[0044] Step 2: Extract the characteristic data of the operation data of the hydrogen energy processing equipment and the hydrogen concentration data collected, and optimize the characteristic data in combination with the abnormal hydrogen concentration situation;
[0045] Extract the characteristic data of the operation data of the hydrogen energy processing equipment and the hydrogen concentration data:
[0046] The fast Fourier transform (FFT) is used to calculate the spectral characteristics of the operation data of the hydrogen energy processing equipment and the hydrogen concentration data collected in Step 1, according to the formula:
[0047]
[0048] where, X(k) represents the spectral data, and x(n) represents the original data;
[0049] After that, calculate the spectral energy distribution in the operation data of the hydrogen energy processing equipment and the hydrogen concentration data, and extract the main frequency component and its amplitude change;
[0050] Set the sliding time window T, and extract the time-domain characteristics of the operation data of the hydrogen energy processing equipment and the hydrogen concentration data within the window, specifically as follows:
[0051] Calculate the mean value Tz1 of the operation data of the hydrogen energy processing equipment and the hydrogen concentration data within the sliding time window T to reflect the overall trend of the operation data of the hydrogen energy processing equipment and the hydrogen concentration data:
[0052]
[0053] Calculate the variance Tz2 of the operation data of the hydrogen energy processing equipment and the hydrogen concentration data within the sliding time window T to measure the volatility of the operation data of the hydrogen energy processing equipment and the hydrogen concentration data:
[0054]
[0055] Calculate the skewness Tz3 of the operation data of the hydrogen energy processing equipment and the hydrogen concentration data within the sliding time window T to describe the symmetry of the distribution of the operation data of the hydrogen energy processing equipment and the hydrogen concentration data:
[0056]
[0057] Calculate the kurtosis Tz4 of the operation data and hydrogen concentration data of the hydrogen energy processing equipment within the sliding time window T to measure the sharpness of the distribution of the operation data and hydrogen concentration data of the hydrogen energy processing equipment:
[0058]
[0059] Furthermore, form the feature data of the operation data and hydrogen concentration data of the hydrogen energy processing equipment into a matrix X, and define each row of the matrix as a sample and each column as a feature. Calculate the covariance matrix C of the feature matrix X, specifically according to the formula:
[0060]
[0061] where m represents the number of samples and Xt represents the transpose of matrix X;
[0062] After that, calculate the eigenvalues λi of the covariance matrix C and their corresponding eigenvectors vi:
[0063]
[0064] Sort the eigenvalues and select the principal components whose cumulative contribution rate exceeds 95%:
[0065]
[0066] where k represents the number of selected principal components and n represents the number of original features;
[0067] Select the first k eigenvectors to form the projection matrix W: W = [v1, v2,..., vk], and map the original feature matrix X to the new low-dimensional feature space: X′ = XW, where X′ represents the dimension-reduced feature data.
[0068] Considering that when the hydrogen concentration of the hydrogen energy processing equipment reaches a certain level, it will affect the operation data of the hydrogen energy processing equipment. Therefore, after each extraction of the feature data of the operation data and hydrogen concentration data of the hydrogen energy processing equipment, set the sliding time window T1 and calculate the hydrogen concentration change rate Rh within the sliding time window T1, specifically according to the formula:
[0069]
[0070] where Ct represents the hydrogen concentration at the current time, Ct-1 represents the hydrogen concentration at the previous time, and S represents the time interval of the sliding window; then, calculate the hydrogen diffusion rate Dh within the sliding time window T1, specifically according to the formula:
[0071]
[0072] Among them, k1 represents the diffusion coefficient, ΔC represents the concentration gradient, and Δx represents the diffusion distance;
[0073] Furthermore, the weighted sum of the hydrogen concentration change rate Rh and the hydrogen diffusion rate Dh is used to determine the current hydrogen concentration change coefficient Qs, and a hydrogen concentration change threshold Yq is set. The hydrogen concentration change coefficient Qs is compared with the hydrogen concentration change threshold Yq. When the hydrogen concentration change coefficient Qs is greater than or equal to the hydrogen concentration change threshold Yq, it indicates that the hydrogen concentration data fluctuates violently when the hydrogen energy processing equipment runs to the time window T1;
[0074] After detecting that the hydrogen concentration of the hydrogen energy processing equipment reaches the threshold and fluctuates violently, the operation data of the hydrogen energy processing equipment is recollected through the arranged sensors, and the error and change rate of the operation data of the hydrogen energy processing equipment before and after the abnormality are calculated. Specifically:
[0075] Calculation of the error Eerr of the operation data of the hydrogen energy processing equipment before and after the abnormality:
[0076] Eerr = |Xpost - Xpre|
[0077] Among them, Xpost represents the operation data of the hydrogen energy processing equipment before the abnormality, and Xpre represents the operation data of the hydrogen energy processing equipment after the abnormality;
[0078] Calculation of the change rate Rchange of the operation data of the hydrogen energy processing equipment before and after the abnormality:
[0079] Rchange = (Xpost - Xpre) / Xpre
[0080] Based on the error Eerr and the change rate Rchange of the operation data of the hydrogen energy processing equipment before and after the abnormality, the weighted sum algorithm is used to adjust and compensate the characteristic data of the operation data of the hydrogen energy processing equipment after dimensionality reduction: Xcomp = Xp + γ × Eerr × Rchange, where γ represents the compensation coefficient, Xp represents the characteristic data of the operation data of the hydrogen energy processing equipment before the abnormality, and Xcomp represents the characteristic data of the operation data of the hydrogen energy processing equipment after compensation after the abnormality.
[0081] After that, the current hydrogen concentration is adjusted through the characteristic data Xcomp of the operation data of the hydrogen energy processing equipment after compensation: Cadj = λ × Xcomp + (1 - λ) × Ccurrent, where Cadj represents the characteristic data of the adjusted hydrogen concentration data, Ccurrent represents the characteristic data of the hydrogen concentration data before the abnormality, and λ represents the adjustment coefficient, and its value range is [0, 1].
[0082] Step 3: Detect the abnormal situation of the hydrogen energy processing equipment based on the clustering analysis technology combined with the feature data deviation degree;
[0083] Based on the feature data extracted in step 2, the optimal number of clusters k2 is determined using the elbow method based on K-Means clustering:
[0084] Calculate the within-cluster sum of squares (WSS) for different values of k2:
[0085]
[0086] Among them, Ci represents the i-th cluster, μi is the cluster center. Then, draw the elbow method curve, find the obvious inflection point of the within-cluster sum of squares (WSS), and determine the value of the optimal number of clusters k;
[0087] Furthermore, use the K-Means++ initialization strategy to randomly initialize k2 random clustering centers, and calculate the Euclidean distance from each data point to the clustering center:
[0088]
[0089] Classify the data points into the nearest cluster according to the minimum distance. Furthermore, calculate the new mean of each cluster:
[0090]
[0091] Update the clustering centers and iterate until the clustering centers no longer change or reach the maximum number of iterations.
[0092] After that, calculate the Euclidean distance from the data points to the clustering center, denoted as D1, and calculate the average distance davg from all data points in the cluster to the center:
[0093]
[0094] Calculate the standard deviation of all data points in the cluster to the center :
[0095]
[0096] And according to 3 rules, set the safety distance threshold Ya. When the Euclidean distance from the data point to the clustering center is greater than or equal to the safety distance threshold Ya, mark the data point as an abnormal data point;
[0097] Furthermore, deploy sensors on each main body of the hydrogen energy processing equipment to collect the data of the main body status. For example, collect pressure data from the hydrogen storage tank and the pipeline; collect temperature data from the booster and the cooling device, collect vibration frequency data from the hydrogen compressor; collect hydrogen flow data of each pipeline;
[0098] Based on the historical operation data of each main body, calculate the feature data deviation degree ΔPy of each main body:
[0099]
[0100] Among them, P represents the characteristic data of each current subject in real time, and Pbenchmark represents the mean value of the characteristic data of each subject; and the mean value Pj and the standard deviation Pb of the characteristic data deviation degree in the historical data are calculated, and an anomaly detection method based on the mean value and the standard deviation is used to analyze the mean value Pj and the standard deviation Pb of the characteristic data deviation degree to determine the deviation threshold Ypy; when the characteristic data deviation degree ΔPy of the subject exceeds the deviation threshold Ypy, it indicates that this non-conventional data point is an anomaly point, and combined with the different operating characteristics of different subjects, the anomaly point types are classified. For example, the anomaly points in the pipeline are leakage anomaly points or blockage anomaly points.
[0101] Furthermore, calculate the number of anomaly points under each subject:
[0102]
[0103] Among them, Nanomaly represents the number of anomaly points under this subject, 1(ΔPyi>Ypy) means that if ΔPy exceeds Ypy, it is recorded as an anomaly, and n represents the number of devices;
[0104] Step 4: Anomaly point grading and warning and future trend prediction;
[0105] According to the characteristic data deviation degree ΔPy of each subject obtained in Step 3, use the outlier detection method Z-score to calculate the anomaly point deviation value of each subject, and determine the anomaly priority of each subject by weighted summing the anomaly point deviation values of each subject and the number of anomaly points under each subject. Use MQTT / Kafka to push the anomaly data in descending order from the subject with the largest anomaly priority to notify the maintenance personnel.
[0106] At the same time, set the historical data window length Td and the prediction time Th, collect the data of the nearest N time windows: X = [Py(t−N), Py(t−N+1),..., Py(t)], and perform normalization processing; construct an LSTM model, and input the data of N time windows into the LSTM model to predict the anomaly points within the future Th time.
[0107] The present invention also proposes an intelligent safety monitoring and warning system for hydrogen energy processing equipment, as Figure 1 shown, including: a data acquisition module, a characteristic data extraction module, an anomaly detection module, a future prediction module, and a data storage module, and the modules are signal-connected to each other;
[0108] The data acquisition module is mainly used to collect the operation data and hydrogen concentration data of the hydrogen energy processing equipment:
[0109] The feature data extraction module is mainly used to extract the feature data of the operation data and hydrogen concentration data of the hydrogen energy processing equipment, and further optimize the feature data in combination with the change of hydrogen concentration:
[0110] The anomaly detection module is mainly used to detect the anomalies of the hydrogen energy processing equipment based on the clustering analysis technology combined with the feature data deviation degree;
[0111] The future prediction module mainly predicts the future operation state and anomaly point trend of the hydrogen energy processing equipment based on historical data and existing data;
[0112] The data storage module is mainly used to store all data during the processing.
[0113] The above formulas are all dimensionless and take their numerical values for calculation. The formula is a formula obtained by collecting a large amount of data for software simulation to get the closest to the real situation. The preset parameters in the formula are set by those skilled in the art according to the actual situation.
[0114] The above embodiments can be implemented in whole or in part by software, hardware, firmware or any other combination. When implemented using software, the above embodiments can be implemented in whole or in part in the form of a computer program product.

Whether these functions are executed in hardware or software depends on the specific application of the technical solution and the invention constraints.
