[0057] Figure 1 A flowchart of a communication signal electromagnetic radiation evaluation and processing method provided by an embodiment of the present invention, as Figure 1 shown, the method includes:

[0058] 101. Obtain real-time monitored electromagnetic radiation data;

[0059] This step refers to the process of obtaining real-time electromagnetic radiation data from sensors or monitoring devices. These data usually include the intensity, frequency and other related parameters of the electromagnetic field. The electromagnetic radiation data can be analog signals or digital signals, depending on the type and configuration of the monitoring device.

[0060] In an embodiment of the present invention, it is assumed that the application scenario is an electromagnetic radiation monitoring system in an industrial production environment. The system aims to monitor the electromagnetic radiation level around production equipment in real time to ensure the safety of employees and the normal operation of equipment.

[0061] Monitoring equipment: The system is equipped with multiple electromagnetic radiation monitoring sensors, which are distributed at key positions in the production facility, such as around equipment, at entrances, etc. These sensors can monitor the electromagnetic radiation intensity in real time and send the data to the central processing unit.

[0062] Data acquisition: The monitoring sensors continuously collect electromagnetic radiation data and transmit the data to the central processing unit at a certain sampling frequency (e.g., once per second). This data usually includes the change trend of electromagnetic radiation intensity over time, as well as information such as frequency components.

[0063] Data format: The collected data can be a digital signal, such as stored in the form of a CSV file or a database record, or it can be an analog signal, which needs to be converted into a digital signal by an analog-to-digital converter for processing.

[0064] Specific embodiment: Suppose 5 electromagnetic radiation monitoring sensors are installed in a factory workshop, and these sensors collect data every 1 second. The monitoring system continuously collects data within 24 hours a day. After the central processing unit receives the data from these sensors, it preprocesses the data, including denoising and smoothing processing, to reduce noise interference and improve the accuracy of subsequent analysis.

[0065] In this way, the system can monitor the electromagnetic radiation level in real time, ensure that abnormal situations can be detected in a timely manner, and take corresponding measures.

[0066] 102. Use a pre-trained anomaly detection model to analyze the preprocessed electromagnetic radiation data to identify electromagnetic radiation signals with abnormal intensity;

[0067] Wherein, the preprocessing at least includes: denoising, smoothing processing, and frequency transformation;

[0068] Before performing step 102, it further includes: performing a Fourier transform on the electromagnetic radiation data to convert it into a frequency-domain signal; using a band-pass filter to filter out noise signals outside a specified frequency range, wherein the specified frequency range is determined according to the frequency range of normal-intensity electromagnetic radiation signals and is used to retain frequency components related to electromagnetic radiation signals with abnormal intensity; applying a sliding window smoothing algorithm to reduce the signal fluctuation of the electromagnetic radiation data.

[0069] Among them, the Fourier transform is a mathematical tool used to convert a time-domain signal into a frequency-domain signal. Through the Fourier transform, electromagnetic radiation data can be converted from the time domain to the frequency domain, making it easier to identify different frequency components in the signal.

[0070] A band-pass filter is a type of filter that allows signals within a specified frequency range to pass through while suppressing signals of other frequencies. In the present invention, the band-pass filter is used to filter out noise signals outside the specified frequency range and retain the frequency components related to the electromagnetic radiation signals of abnormal intensity.

[0071] The sliding window smoothing algorithm is an algorithm used to reduce signal fluctuations. By moving a window over the data and averaging the data within the window, random fluctuations in the signal can be reduced, improving the smoothness of the signal.

[0072] In an embodiment of the present invention, it is assumed that the application scenario is an electromagnetic radiation monitoring system in an industrial production environment. The system aims to monitor the electromagnetic radiation level around production equipment in real time to ensure the safety of employees and the normal operation of the equipment.

[0073] The system is equipped with multiple electromagnetic radiation monitoring sensors, which are distributed at key locations in the production facility. The original electromagnetic radiation data collected by the sensors is first converted into a frequency-domain signal through the Fourier transform to analyze the frequency components of the signal. Then, a band-pass filter is used to filter out noise signals outside the specified frequency range, where the specified frequency range is determined according to the frequency range of the electromagnetic radiation signals of normal intensity to ensure that the frequency components related to the electromagnetic radiation signals of abnormal intensity are retained. Finally, the sliding window smoothing algorithm is applied to reduce the signal fluctuations of the electromagnetic radiation data, improving the smoothness and continuity of the signal.

[0074] Based on the above, when performing step 102, it may specifically include: using a long short-term memory network for time series prediction to identify electromagnetic radiation signals of abnormal intensity by capturing long-term dependencies in the electromagnetic radiation data; and / or, combining with an autoencoder to identify electromagnetic radiation signals of abnormal intensity by reconstructing the difference between the electromagnetic radiation signals of normal intensity and the electromagnetic radiation data; and / or, using a support vector machine for classification to distinguish between electromagnetic radiation signals of normal intensity and abnormal intensity by constructing an optimal hyperplane.

[0075] In this step, the long short-term memory network (LSTM) is a special type of recurrent neural network (RNN) that can capture long-term dependencies in data. In the present invention, the LSTM is used to capture long-term dependencies in the electromagnetic radiation data to identify electromagnetic radiation signals of abnormal intensity.

[0076] An autoencoder (AE) is an unsupervised learning model that can be used for data dimensionality reduction and feature learning. In the present invention, the autoencoder identifies electromagnetic radiation signals with abnormal intensities by reconstructing the difference between electromagnetic radiation signals with normal intensities and electromagnetic radiation data.

[0077] A support vector machine (SVM) is a supervised learning model used for classification and regression analysis. In the present invention, the SVM distinguishes electromagnetic radiation signals with normal intensities from those with abnormal intensities by constructing an optimal hyperplane.

[0078] In an embodiment of the present invention, after the above data collection and preprocessing, the system analyzes the preprocessed electromagnetic radiation data using a pre-trained anomaly detection model. Specifically, a long short-term memory network (LSTM) is used for time series prediction to identify electromagnetic radiation signals with abnormal intensities by capturing long-term dependencies in the electromagnetic radiation data. At the same time, an autoencoder (AE) is combined to identify electromagnetic radiation signals with abnormal intensities by reconstructing the difference between electromagnetic radiation signals with normal intensities and electromagnetic radiation data. In addition, a support vector machine (SVM) is adopted for classification to distinguish electromagnetic radiation signals with normal intensities from those with abnormal intensities by constructing an optimal hyperplane.

[0079] For example, assume that 5 electromagnetic radiation monitoring sensors are installed in a factory workshop, and these sensors collect data every 1 second. The monitoring system continuously collects data within 24 hours a day. After the central processing unit receives the data from these sensors, it preprocesses the data, including Fourier transform, band-pass filtering, and sliding window smoothing. Then, a pre-trained anomaly detection model is used for analysis, and this model includes components such as LSTM, AE, and SVM. Through the joint work of these components, the system can identify electromagnetic radiation signals with abnormal intensities and evaluate them.

[0080] In this way, the system can monitor the electromagnetic radiation level in real time, ensure that abnormal situations can be detected in a timely manner, and take corresponding measures.

[0081] 103. Calculate the characteristic parameters of the electromagnetic radiation signal with abnormal intensity;

[0082] In this step, the characteristic parameters at least include time-weighted average radiation intensity, peak intensity, energy density, and spectral entropy;

[0083] The specific execution process of step 103 may include:

[0084] Through the formula: , calculate the time-weighted average radiation intensity of the electromagnetic radiation signal with abnormal intensity; where, represents the time-weighted average radiation intensity, represents the radiation intensity at the i-th moment, and N represents the number of sampling points, represents the weight function based on time, where, , represents the attenuation coefficient, represents the time difference between the i-th moment and the reference moment;

[0085] Through the formula: , calculate the peak intensity of the electromagnetic radiation signal with abnormal intensity, where P represents the peak intensity, represents the radiation intensity at the i-th moment, i = {1, 2,..., N};

[0086] Through the formula: , calculate the energy density of the electromagnetic radiation signal with abnormal intensity; where E represents the energy density, represents the sampling interval, represents the weight function based on energy, where, ;

[0087] Through the formula: , calculate the spectral entropy of the electromagnetic radiation signal with abnormal intensity; where S represents the spectral entropy, represents the power ratio of the j-th frequency component, and M represents the total number of frequency components.

[0088] In this step, the time-weighted average radiation intensity is the weighted average of the radiation intensities of the electromagnetic radiation data at different time points to consider the importance of different time points. The weight function decays according to the time difference from the reference moment, where represents the attenuation coefficient.

[0089] The peak intensity refers to the maximum radiation intensity value in the electromagnetic radiation data, which reflects the maximum intensity of the signal.

[0090] The energy density calculates the energy of the electromagnetic radiation data, considering the radiation intensity and sampling interval of each sampling point. The weight function based on energy is weighted according to the ratio of the radiation intensity to the time-weighted average radiation intensity.

[0091] The spectral entropy is a statistic based on the spectral distribution, used to measure the uniformity of the spectral distribution. It is obtained by calculating the logarithm weighted sum of the power ratios of different frequency components.

[0092] In an embodiment of the present invention, it is assumed that the application scenario is an electromagnetic radiation monitoring system in an industrial production environment. The system aims to monitor the electromagnetic radiation level around production equipment in real time to ensure the safety of employees and the normal operation of equipment.

[0093] First, the system is equipped with multiple electromagnetic radiation monitoring sensors, which are distributed at key positions in the production facility. The original electromagnetic radiation data collected by the sensors is first converted into a frequency-domain signal through Fourier transform to analyze the frequency components of the signal. Then, a band-pass filter is used to filter out noise signals outside the specified frequency range, where the specified frequency range is determined according to the frequency range of electromagnetic radiation signals with normal intensity to ensure that the frequency components related to electromagnetic radiation signals with abnormal intensity are retained. Finally, a sliding window smoothing algorithm is applied to reduce the signal fluctuations of the electromagnetic radiation data and improve the smoothness and continuity of the signal.

[0094] Furthermore, after the preprocessed electromagnetic radiation data is analyzed using a pre-trained anomaly detection model, the characteristic parameters of the electromagnetic radiation signal with abnormal intensity are further calculated. The specific steps are as follows:

[0095] Time-weighted average radiation intensity: Through the formula: , calculate the time-weighted average radiation intensity of the electromagnetic radiation signal with abnormal intensity; where , represents the attenuation coefficient, represents the time difference between the i-th moment and the reference moment;

[0096] Peak intensity: Through the formula: , calculate the peak intensity of the electromagnetic radiation signal with abnormal intensity;

[0097] Energy density: Through the formula: , calculate the energy density of the electromagnetic radiation signal with abnormal intensity; where ;

[0098] Spectral entropy: Through the formula: , calculate the spectral entropy of the electromagnetic radiation signal with abnormal intensity, where represents the power ratio of the j-th frequency component;

[0099] For example, assume that 5 electromagnetic radiation monitoring sensors are installed in a factory workshop, and these sensors collect data every 1 second. The monitoring system continuously collects data within 24 hours a day. After the central processing unit receives the data from these sensors, it preprocesses the data, including Fourier transform, band-pass filtering, and moving window smoothing. Then, it uses a pre-trained anomaly detection model for analysis. For each electromagnetic radiation signal with abnormal intensity, the system calculates its characteristic parameters, including time-weighted average radiation intensity, peak intensity, energy density, and spectral entropy.

[0100] Time-weighted average radiation intensity: Assume the attenuation coefficient λ = 0.1, and calculate the time-weighted average radiation intensity of each abnormal signal.

[0101] Peak intensity: Directly calculate the maximum radiation intensity of each abnormal signal.

[0102] Energy density: Considering the sampling interval Δt = 1 second, calculate the energy density of each abnormal signal.

[0103] Spectral entropy: Calculate the spectral entropy of each abnormal signal to evaluate the uniformity of the spectral distribution.

[0104] In this way, the system can calculate the characteristic parameters of the electromagnetic radiation signals with abnormal intensity, providing data support for subsequent evaluation and processing.

[0105] 104. According to the characteristic parameters, evaluate the anomaly level of the electromagnetic radiation signal with abnormal intensity through a preset evaluation rule;

[0106] As a possible implementation method, step 104 may include: when the time-weighted average radiation intensity of the electromagnetic radiation signal with abnormal intensity exceeds the preset threshold T1, it is determined as a first-level anomaly; when the peak intensity of the electromagnetic radiation signal with abnormal intensity exceeds the preset threshold T2, it is determined as a second-level anomaly; when the energy density of the electromagnetic radiation signal with abnormal intensity exceeds the preset threshold T3, it is determined as a third-level anomaly; when the spectral entropy of the electromagnetic radiation signal with abnormal intensity is lower than the preset threshold T4, it is determined as a fourth-level anomaly.

[0107] In this implementation method, the preset threshold is a value set according to specific criteria and is used to determine whether the electromagnetic radiation signal reaches an abnormal state. These thresholds can be determined based on historical data, industry standards, or other factors.

[0108] The anomaly level is determined based on the comparison result between the characteristic parameters and the preset threshold and is used to represent the abnormal degree of the electromagnetic radiation signal. Different anomaly levels represent different degrees of abnormal states.

[0109] As another possible implementation, step 104 may include: defining an abnormal level calculation formula: ;

[0110] where G represents the abnormal level, w1, w2, w3, and w4 respectively represent the importance weights of the time-weighted average radiation intensity, peak intensity, energy density, and spectral entropy, and T1, T2, T3, and T4 respectively represent the preset thresholds of the corresponding characteristic parameters.

[0111] where the calculation formulas for the importance weights w1, w2, w3, and w4 are:

[0112] ;

[0113] where λ is a parameter for adjusting the steepness of the curve, and σ1, σ2, σ3, and σ4 are respectively the calibration factors of the corresponding characteristic parameters, , , , respectively represent the averages of the corresponding characteristic parameters, represents the time-weighted average radiation intensity, P represents the peak intensity, E represents the energy density, and S represents the spectral entropy.

[0114] In this implementation, the importance weights are used to represent the relative importance of different characteristic parameters when evaluating the abnormal level. These weights can be calculated by formulas to ensure that the evaluation results are more reasonable.

[0115] The abnormal level calculation formula is a method for calculating the abnormal level based on the thresholds and importance weights of the characteristic parameters. Through this formula, multiple characteristic parameters can be comprehensively considered to determine the abnormal level.

[0116] In the embodiments of the present invention, it is assumed that the application scenario is an electromagnetic radiation monitoring system in an industrial production environment. The system aims to monitor the electromagnetic radiation level around production equipment in real time to ensure the safety of employees and the normal operation of equipment.

[0117] The system is equipped with multiple electromagnetic radiation monitoring sensors, which are distributed at key positions of the production facility. The original electromagnetic radiation data collected by the sensors is first converted into a frequency-domain signal through Fourier transform to analyze the frequency components of the signal. Then, a band-pass filter is used to filter out the noise signals outside the specified frequency range, where the specified frequency range is determined according to the frequency range of the electromagnetic radiation signal with normal intensity to ensure that the frequency components related to the electromagnetic radiation signal with abnormal intensity are retained. Finally, a sliding window smoothing algorithm is applied to reduce the signal fluctuation of the electromagnetic radiation data and improve the smoothness and continuity of the signal.

[0118] After the system analyzes the preprocessed electromagnetic radiation data using a pre-trained anomaly detection model, it further calculates the characteristic parameters of the electromagnetic radiation signals with abnormal intensity, including the time-weighted average radiation intensity, peak intensity, energy density, and spectral entropy.

[0119] Based on the calculated characteristic parameters, the system evaluates the anomaly level of the electromagnetic radiation signals with abnormal intensity through a preset evaluation rule. The specific steps are as follows:

[0120] Threshold comparison: The system sets preset thresholds T1, T2, T3, and T4 for the time-weighted average radiation intensity, peak intensity, energy density, and spectral entropy respectively. When the characteristic parameters exceed these thresholds, the system determines the corresponding anomaly level.

[0121] Anomaly level calculation formula: The system can also use the anomaly level calculation formula: ;

[0122] where G represents the anomaly level, w1, w2, w3, and w4 represent the importance weights of the time-weighted average radiation intensity, peak intensity, energy density, and spectral entropy respectively. The system calculates the importance weights w1, w2, w3, and w4 according to the above weight calculation formula, and T1, T2, T3, and T4 represent the preset thresholds of the corresponding characteristic parameters.

[0123] For example, assume that 5 electromagnetic radiation monitoring sensors are installed in a factory workshop, and these sensors collect data every 1 second. The monitoring system continuously collects data within 24 hours a day. After the central processing unit receives the data from these sensors, it preprocesses them, including Fourier transform, band-pass filtering, and sliding window smoothing. Then, it uses a pre-trained anomaly detection model for analysis and calculates the characteristic parameters of the electromagnetic radiation signals with abnormal intensity. Then, the system evaluates the anomaly level based on these characteristic parameters.

[0124] Threshold comparison: Assume that the preset thresholds are T1 = 10, T2 = 20, T3 = 500, and T4 = 0.5, and the system determines the anomaly level according to these thresholds.

[0125] Anomaly level calculation formula: The system calculates the importance weights according to the formula. Assume that λ = 0.5, σ1 = 1.2, σ2 = 1.1, σ3 = 1.0, and σ4 = 0.9, and the average values of the corresponding characteristic parameters are = 5, = 15, = 300, = 0.7. Substitute these values into the above importance weight calculation formula to obtain the importance weights w1 = 0.4, w2 = 0.3, w3 = 0.2, and w4 = 0.1. Then, the system uses the anomaly level calculation formula again: Calculate the anomaly level.

[0126] In this way, the system can evaluate the anomaly level based on the characteristic parameters and preset thresholds, and take corresponding measures according to the anomaly level.

[0127] 105. Output the evaluation result, where the evaluation result at least includes the anomaly level and the corresponding handling measures for the anomaly level.

[0128] In this step, outputting the evaluation result means presenting the evaluated anomaly level and the corresponding handling measures in an appropriate form. This step is the last step of the entire evaluation process, aiming to enable relevant personnel to clearly understand the monitoring results and their corresponding measures.

[0129] The anomaly level is determined based on the comparison result between the characteristic parameters and the preset thresholds, and is used to represent the anomaly degree of the electromagnetic radiation signal. Different anomaly levels represent different degrees of abnormal states.

[0130] The handling measures are the corresponding measures taken for different anomaly levels. These measures aim to mitigate or eliminate the potential risks brought by the abnormal situation.

[0131] In the embodiment of the present invention, it is assumed that the application scenario is an electromagnetic radiation monitoring system in an industrial production environment. This system aims to monitor the electromagnetic radiation level around production equipment in real time to ensure the safety of employees and the normal operation of equipment.

[0132] The system outputs the anomaly level and the corresponding handling measures according to the evaluation result. The specific steps are as follows:

[0133] Anomaly level output: The system outputs the corresponding level information according to the evaluated anomaly level, for example: "Level 1 anomaly", "Level 2 anomaly", etc.

[0134] Handling measures: The system outputs the corresponding handling measures according to the anomaly level. For example, for a "Level 1 anomaly", it is recommended to take emergency measures such as shutting down relevant equipment and evacuating personnel; for a "Level 2 anomaly", it is recommended to strengthen monitoring and regularly check the equipment status; for a "Level 3 anomaly", it is recommended to perform equipment maintenance and inspection; for a "Level 4 anomaly", it is recommended to adjust the equipment working state or parameter settings.

[0135] In this way, the system can evaluate the anomaly level based on the characteristic parameters and preset thresholds, and take corresponding measures according to the anomaly level to ensure that abnormal situations can be detected in time and appropriate actions can be taken.
