Technical Field

[0001] The present invention relates to the technical field of data processing, and in particular to a data analysis method for an electromagnetic pulse field. Background Art

[0002] Lightning discharge, partial discharge of electrical equipment and other phenomena will generate electromagnetic pulses. For working equipment, protection design will be carried out to avoid the impact of electromagnetic pulses that may lead to performance degradation or even aging. However, since the protection design cannot completely cover all possible electromagnetic pulse situations, the equipment itself can only protect against electromagnetic pulses within a certain energy range. Therefore, it is also necessary to monitor the equipment for possible electromagnetic pulse damage.

[0003] At present, the detection methods for electromagnetic pulses are relatively mature, and the problem that needs to be solved is how to reasonably monitor the enveloped equipment in the field involved in the electromagnetic pulse, so as to provide an accurate reference for the working status and performance of the equipment. This requires reasonable analysis and processing of the data obtained in the electromagnetic pulse field to achieve timely monitoring, judgment and analysis.

[0004] Therefore, it is an urgent problem to be solved to design a data analysis method for electromagnetic pulse fields, and to accurately monitor and judge the degree of impact on equipment in the field by acquiring electromagnetic pulse data from all sources in the electromagnetic pulse field area and conducting reasonable analysis and processing. Summary of the invention

[0005] The purpose of the present invention is to provide a data analysis method for an electromagnetic pulse field, which collects pulse signal data of a target field area and performs feature extraction based on electromagnetic pulse data from different sources to form feature data information of electromagnetic pulses from all sources in the field area. In combination with the anti-electromagnetic pulse information of all equipment in the field area, the equipment is analyzed to see whether it is interfered by the electromagnetic pulse, thereby being able to determine the equipment affected by the electromagnetic pulse and provide early warning information for the equipment in a timely manner. Through the early warning, the affected equipment can be located in real time to provide real-time data reference for the equipment operation status, thereby avoiding the adverse effects on normal operation caused by the inability to know the performance degradation or failure of the equipment.

[0006] In a first aspect, the present invention provides a method for analyzing electromagnetic pulse field data, comprising collecting electromagnetic pulse signal data of a target field area, and performing pulse signal feature extraction to form field area pulse feature data; obtaining anti-pulse performance data of all equipment in the target field area, and performing interference analysis in combination with the field area pulse feature data to form equipment interference impact data; performing early warning analysis based on the equipment interference impact data to form equipment interference early warning data.

[0007] In the present invention, the method collects pulse signal data of the target field area and performs feature extraction based on electromagnetic pulse data from different sources to form feature data information of electromagnetic pulses from all sources in the field area. In combination with the anti-electromagnetic pulse information of all equipment in the field area, the equipment is analyzed to see whether it is interfered by the electromagnetic pulse, thereby determining the equipment affected by the electromagnetic pulse and providing early warning information for the equipment in a timely manner. The affected equipment can be located instantly through the early warning to provide real-time data reference for the equipment operation status, thereby avoiding the adverse effects on normal operation caused by the inability to know the performance degradation or failure of the equipment.

[0008] As a possible implementation method, electromagnetic pulse signal data of the target field is collected, and pulse signal feature extraction is performed to form field pulse feature data, including: determining the source pulse change function of different source electromagnetic pulses in the time domain according to the electromagnetic pulse signal data of the target field , n represents the number of different source electromagnetic pulses; according to the electromagnetic pulse signal data of the target field area, the source pulse frequency change function of different source electromagnetic pulses in the time dimension sequence is determined ; Source pulse variation function of all source electromagnetic pulses in the target field area and source pulse frequency variation function , forming field pulse characteristic data.

[0009] In the present invention, in order to determine whether the equipment in the field area is likely to be affected by the electromagnetic pulse, it is necessary to first accurately extract information about the electromagnetic pulses occurring in the field area. Considering that the impact of electromagnetic pulses on the equipment is mainly that its electromagnetic induction generates a large induced current and damages the electrical components of the equipment, the main features considered when extracting information from the electromagnetic pulses are the change of the amplitude of the electromagnetic pulse over time and the change of the frequency of the electromagnetic pulse over time. Although the amplitude and frequency are not directly related to the generation of induced current, they play a positively correlated role in the main factors that generate induced current, such as having a certain degree of influence on the magnetic flux, that is, the larger the amplitude, the higher the magnetic flux, and the larger the frequency, the higher the energy density per unit time, that is, the density of the magnetic flux per unit time. At the same time, considering that multiple electromagnetic pulses will be generated in the target field area, it is necessary to extract features separately to fully consider the impact of all electromagnetic pulses on the equipment.

[0010] As a possible implementation method, the anti-pulse performance data of all equipment in the target area is obtained, and interference analysis is performed in combination with the pulse characteristic data of the area to form equipment interference impact data, including: obtaining the anti-pulse performance data of all equipment in the target area, and according to the source pulse change function corresponding to different source electromagnetic pulses and source pulse frequency variation function , conduct interference analysis of a single pulse source to form interference impact data of a single pulse source; obtain the anti-pulse performance data of all equipment in the target area, and combine the source pulse change function corresponding to different source electromagnetic pulses , conduct pulse source combined interference analysis to form combined pulse source interference impact data; combine single pulse source interference impact data and combined pulse source interference impact data to form equipment interference impact data.

[0011] In the present invention, of course, whether the electromagnetic pulse affects the performance of the equipment can be accurately determined by extracting the characteristic information of the electromagnetic pulse and comparing it with the electromagnetic pulse range that the equipment can protect. If different electromagnetic pulses occur at the same time point, there will be energy superposition. Therefore, when considering whether each electromagnetic pulse affects the performance of the equipment, it is also necessary to consider the situation where the energy superposition of different electromagnetic pulses affects the performance of the equipment. Therefore, the interference analysis of the equipment includes the impact analysis of a single pulse source and the impact analysis of comprehensive multi-source pulses.

[0012] As a possible implementation method, the anti-pulse performance data of all equipment in the target area is obtained, and the source pulse change function corresponding to different source electromagnetic pulses is used. and source pulse frequency variation function , conduct interference analysis of a single pulse source and form interference impact data of a single pulse source, including: obtaining the continuous reception time change function of different devices , where m represents the number of different devices, Indicates the continuous receiving pulse amplitude value corresponding to the device numbered m. , Indicates the acceptable pulse energy range, Indicates the continuous receiving pulse frequency value corresponding to the device numbered m. , Indicates the frequency range of the received pulse; according to the source pulse change function corresponding to different source electromagnetic pulses and source pulse frequency variation function , and combined with the continuous reception duration change function corresponding to different devices , conduct interference analysis and form single pulse source interference impact data.

[0013] In the present invention, for the equipment, in order to be able to work stably and continuously in an environment with electromagnetic pulses, it is necessary to carry out a certain degree of anti-electromagnetic pulse design, and this protection has certain limitations and cannot include all possible electromagnetic pulses. Therefore, when analyzing whether the electromagnetic pulse has an impact on the equipment, it is necessary to compare and analyze its protection performance information with the characteristic information of all electromagnetic pulses in the field. Here, the electromagnetic pulse protection of the equipment mainly considers the elimination and prevention of the induced current generated by the electromagnetic pulse, and in order to be able to reasonably compare and analyze with the characteristic information of the electromagnetic pulse, the protection performance of the equipment obtained also considers the frequency and amplitude of the electromagnetic pulse that it can protect and the duration of continuous protection at the corresponding pulse frequency and amplitude. By extracting the protection characteristic information of the equipment in this aspect, it is possible to achieve an accurate and reasonable comparison with the characteristic information of the electromagnetic pulse, and then determine whether the equipment is affected in the electromagnetic pulse environment.

[0014] As a possible implementation method, according to the source pulse change function corresponding to different source electromagnetic pulses and source pulse frequency variation function , and combined with the continuous reception duration change function corresponding to different devices , conduct interference analysis to form single pulse source interference impact data, including: source pulse change function corresponding to different source electromagnetic pulses , determine the corresponding maximum amplitude , according to the source pulse frequency variation function of different source electromagnetic pulses , determine the maximum amplitude Corresponding amplitude frequency ; According to the maximum amplitude corresponding to electromagnetic pulses from different sources and amplitude frequency , and combined with the continuous reception duration change function corresponding to different devices , the following interference analysis is performed: for any source electromagnetic pulse, if the continuous receiving time variation function The maximum amplitude Equal continuous pulse amplitude values The corresponding minimum acceptance frequency is greater than the amplitude frequency , then there is no single pulse source interference information; for any source electromagnetic pulse, if the continuous reception time variation function Lower and amplitude frequency Equal continuous pulse frequency value The corresponding minimum acceptable amplitude is greater than the maximum amplitude , then there is no single pulse source interference information; for any source electromagnetic pulse, if the continuous reception time variation function The maximum amplitude Equal continuous pulse amplitude values There is a corresponding acceptance frequency and amplitude frequency If they are equal, then according to the source pulse change function and source pulse frequency variation function , determine the maximum amplitude and amplitude frequency Continuous pulse duration: When the pulse duration is not greater than the continuous receiving duration change function The determined reception duration will form a single pulse source interfering with the acceptable information; when the pulse duration is greater than the continuous reception duration variation function The determined reception duration will form a single pulse source continuous interference information; for any source electromagnetic pulse, if the continuous reception duration change function Lower and amplitude frequency Equal continuous pulse frequency value There is a corresponding acceptance amplitude and maximum amplitude If they are equal, then according to the source pulse change function and source pulse frequency variation function , determine the maximum amplitude and amplitude frequency Continuous pulse duration: When the pulse duration is not greater than the continuous receiving duration change function The determined reception duration will form a single pulse source interfering with the acceptable information; when the pulse duration is greater than the continuous reception duration variation function The determined reception duration will form a single pulse source continuous interference information; for any source electromagnetic pulse, if the continuous reception duration change function The maximum amplitude Equal continuous pulse amplitude values The corresponding maximum acceptance frequency is less than the amplitude frequency , then a single pulse source instant interference information is formed; for any source electromagnetic pulse, if the continuous receiving time variation function Lower and amplitude frequency Equal continuous pulse frequency value The corresponding maximum accepted amplitude is less than the maximum amplitude , then a single pulse source instant interference information is formed.

[0015] In the present invention, the impact of a single pulse source on the equipment mainly considers whether the amplitude and frequency of the electromagnetic pulse exceed the acceptable range of the equipment protection. The following situations may occur when comparing the equipment protection feature data with the electromagnetic pulse feature information: one is that the maximum amplitude and frequency of all electromagnetic pulses are smaller than the amplitude and frequency that the equipment needs to protect. In this case, any single electromagnetic pulse will not affect any equipment at all; the second situation is that the maximum amplitude and frequency of all electromagnetic pulses are within the amplitude and frequency range that the equipment needs to protect. This situation indicates that there are some electromagnetic pulses with large amplitudes and frequencies that can affect the equipment, but they are just within the range that the equipment can protect. However, this protection is sometimes not able to continue all the time, so it is necessary to determine whether the duration of the maximum amplitude and frequency of the electromagnetic pulse is within the corresponding duration of the continuous protection under the electromagnetic pulse that the equipment can protect. The third situation is that the maximum amplitude and frequency of all electromagnetic pulses exceed the amplitude and frequency range that the equipment can protect. This situation indicates that the protection of some electromagnetic pulse equipment cannot prevent it from causing damage to the equipment. According to different comparative analysis situations, different interference situation result information is formed, thereby providing accurate data reference for subsequent early warning analysis.

[0016] As a possible implementation method, the anti-pulse performance data of all equipment in the target area is obtained, and the source pulse change function corresponding to different source electromagnetic pulses is combined , conduct pulse source combined interference analysis to form combined pulse source interference impact data, including: source pulse change function corresponding to different source electromagnetic pulses , perform multi-source energy superposition processing to form a multi-source pulse change function corresponding to the target field area , and according to the multi-source pulse variation function , determine the multi-source pulse comprehensive frequency change function of the target field ; According to the multi-source pulse variation function and multi-source pulse comprehensive frequency variation function , and combined with the continuous reception duration change function corresponding to different devices , conduct combined interference analysis and form combined pulse source interference impact data.

[0017] In the present invention, different electromagnetic pulses have energy superposition, especially in different electromagnetic pulses with close phases. Since the peaks and troughs of energy are close, there may be positive superposition of energy at the maximum, thereby forming a stronger pulse energy. Therefore, it is necessary to conduct multi-source comprehensive analysis of different electromagnetic pulses. To achieve comprehensive impact analysis of multi-source electromagnetic pulses, it is necessary to merge and analyze different electromagnetic pulse data. There are various ways to merge, such as Fourier transform, direct superposition in the time domain, etc., to finally form combined electromagnetic pulse feature information. Similarly, the combined electromagnetic pulse feature information also considers the two aspects of amplitude and frequency to achieve reasonable and accurate comparative analysis with the protection feature information of the equipment.

[0018] As a possible implementation method, according to the multi-source pulse variation function and multi-source pulse comprehensive frequency variation function , and combined with the continuous reception duration change function corresponding to different devices , conduct combined interference analysis to form combined pulse source interference impact data, including: according to the multi-source pulse change function , determine the maximum integrated amplitude , according to the multi-source pulse comprehensive frequency change function , determine the maximum integrated amplitude The corresponding comprehensive mapping frequency ; For any device, if it continues to receive the duration change function The maximum integrated amplitude Equal continuous pulse amplitude values The corresponding minimum acceptance frequency is greater than the comprehensive mapping frequency , then no combined pulse interference information is formed; for any device, if it continues to receive the time-varying function On and integrated mapping frequency Equal continuous pulse frequency value The corresponding minimum accepted amplitude is greater than the maximum integrated amplitude , then no combined pulse interference information is formed; for any device, if it continues to receive the time-varying function The maximum integrated amplitude Equal continuous pulse amplitude values There is a corresponding continuous pulse frequency value With comprehensive mapping frequency If they are equal, then according to the multi-source pulse variation function and multi-source pulse comprehensive frequency variation function , determine the maximum integrated amplitude and the comprehensive mapping frequency The continuous comprehensive duration: when the comprehensive duration is not greater than the continuous acceptance duration change function The determined reception duration will form a combined pulse that can accept interference information; when the combined duration is greater than the continuous reception duration variation function Determine the reception duration, then form the combined pulse continuous interference information; for any device, if the continuous reception duration change function On and integrated mapping frequency Equal continuous pulse frequency value There is a corresponding continuous receiving pulse amplitude value The maximum integrated amplitude If they are equal, then according to the multi-source pulse variation function and multi-source pulse comprehensive frequency variation function , determine the maximum integrated amplitude and the comprehensive mapping frequency The continuous comprehensive duration: when the comprehensive duration is not greater than the continuous acceptance duration change function The determined reception duration will form a combined pulse that can accept interference information; when the combined duration is greater than the continuous reception duration variation function Determine the reception duration, then form the combined pulse continuous interference information; for any device, if the continuous reception duration change function The maximum integrated amplitude Equal continuous pulse amplitude values The corresponding maximum acceptance frequency is less than the comprehensive mapping frequency , then the combined pulse instant interference information is formed; for any device, if it continuously receives the time-varying function On and integrated mapping frequency Equal continuous pulse frequency value The corresponding maximum accepted amplitude is less than the maximum integrated amplitude , then the combined pulse instant interference information is formed.

[0019] In the present invention, the interference analysis of the combined pulse on the equipment is also determined by analyzing the amplitude and frequency of the pulse and comparing them with the protection characteristics of the equipment. The results of this comparative analysis are as follows: one is that the maximum amplitude and frequency of the combined pulse are less than the minimum amplitude and frequency of any equipment for protection. This situation indicates that the combined effect of all electromagnetic pulses will not affect the equipment. The second is that the maximum amplitude and frequency of the combined pulse are within the range of equipment protection. In this case, it is necessary to determine whether the duration of the maximum amplitude and frequency of the combined pulse exceeds the duration corresponding to the equipment protection. The third situation is that the maximum amplitude and frequency of the combined pulse exceed the range that the equipment can protect. In this case, the combined effect of the electromagnetic pulse directly affects the equipment.

[0020] As a possible implementation method, early warning analysis is performed based on the equipment interference impact data to form equipment interference early warning data, including: obtaining single pulse source interference impact data and combined pulse source interference impact data corresponding to different equipment, and classifying the equipment into early warning types according to different interference categories to form equipment early warning classification result data; based on the equipment early warning classification result data, different early warning operation prompt information is formed.

[0021] In the present invention, by obtaining the single pulse source interference analysis results and the combined pulse source interference analysis results of different devices, the interference type of the device is located, so that corresponding reasonable warning information can be provided to accurately prompt the situation of the device.

[0022] As a possible implementation method, single pulse source interference impact data and combined pulse source interference impact data corresponding to different devices are obtained, and the devices are divided into warning types according to different interference categories to form device warning classification result data, including: single pulse source interference impact data are calibrated into the following interference categories: no single pulse source interference information is calibrated as a non-warning category, single pulse source interference acceptable information is calibrated as a first-level warning category, single pulse source continuous interference information is calibrated as a second-level warning category, and single pulse source immediate interference information is calibrated as a third-level warning category; combined pulse source interference impact data are calibrated into the following interference categories: no combined pulse interference information is calibrated as a non-warning category, combined pulse acceptable interference information is calibrated as a first-level warning category, combined pulse continuous interference information is calibrated as a second-level warning category, and combined pulse immediate interference information is calibrated as a third-level warning category; for different devices, according to the corresponding single pulse source interference impact data and combined pulse source interference impact data, the highest warning category is determined, and the highest warning category is used as the equipment warning category corresponding to the device; according to the equipment warning categories corresponding to different devices, unified category clustering is performed to form different warning device sets.

[0023] In the present invention, regardless of the analysis results of a single pulse source or a combined pulse source, their impact on the device is equivalent in the same category. Therefore, when categorizing the device, selecting the highest category to which the device is subjected as the interference level of the device can truly reflect the interference situation of the device.

[0024] As a possible implementation method, different warning operation prompt information is formed according to the equipment warning classification result data, including: forming normal operation information for the warning equipment set whose warning category is the non-warning category; forming inspection and test operation prompt information for the warning equipment set whose warning category is the first-level warning category; forming inspection and test operation prompt information for the warning equipment set whose warning category is the second-level warning category; forming maintenance operation prompt information for the warning equipment set whose warning category is the third-level warning category.

[0025] In the present invention, due to the different interference levels of the equipment, the damage caused to the equipment is also different. Especially for the first and second level categories, although the equipment can provide a certain degree of protection, it is still necessary to provide an early warning of inspection and testing to determine whether the equipment can work normally. For the third level category, the equipment is definitely not damaged by the electromagnetic pulse, so an early warning of maintenance can be directly provided.

[0026] The beneficial effects of the electromagnetic pulse field data analysis method provided by the present invention are as follows: This method collects pulse signal data from the target area and extracts features based on electromagnetic pulse data from different sources to form feature data information of electromagnetic pulses from all sources in the area. Combined with the anti-electromagnetic pulse information of all equipment in the area, the equipment is analyzed to see whether it is interfered with by the electromagnetic pulse. The equipment affected by the electromagnetic pulse can be determined, and early warning information for the equipment can be provided in a timely manner. The affected equipment can be located instantly through the early warning, providing real-time data reference for the equipment operation status, thereby avoiding the adverse effects on normal operation caused by the lack of knowledge of equipment performance degradation or failure.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] Lightning discharge, partial discharge of electrical equipment and other phenomena will generate electromagnetic pulses. For working equipment, protection design will be carried out to avoid the impact of electromagnetic pulses that may lead to performance degradation or even aging. However, since the protection design cannot completely cover all possible electromagnetic pulse situations, the equipment itself can only protect against electromagnetic pulses within a certain energy range. Therefore, it is also necessary to monitor the equipment for possible electromagnetic pulse damage.

[0031] At present, the detection methods for electromagnetic pulses are relatively mature, and the problem that needs to be solved is how to reasonably monitor the enveloped equipment in the field involved in the electromagnetic pulse, so as to provide an accurate reference for the working status and performance of the equipment. This requires reasonable analysis and processing of the data obtained in the electromagnetic pulse field to achieve timely monitoring, judgment and analysis.

[0032] refer to Figure 1~Figure 3 The embodiment of the present invention provides a data analysis method for an electromagnetic pulse field. The method collects pulse signal data of a target field area and performs feature extraction based on electromagnetic pulse data from different sources to form feature data information of electromagnetic pulses from all sources in the field area. The method analyzes whether the equipment is interfered by the electromagnetic pulse in combination with the anti-electromagnetic pulse information of all equipment in the field area, thereby determining the equipment affected by the electromagnetic pulse and providing early warning information for the equipment in a timely manner. The affected equipment can be located instantly through the early warning to provide real-time data reference for the equipment operation status, thereby avoiding the adverse effects on normal operation caused by the inability to know the performance degradation or failure of the equipment.

[0033] The data analysis method of the electromagnetic pulse field specifically includes the following steps: S1: Collect electromagnetic pulse signal data of the target field area, and extract pulse signal features to form field pulse feature data.

[0034] Collect the electromagnetic pulse signal data of the target field area, and extract the pulse signal characteristics to form the field area pulse characteristic data, including: according to the electromagnetic pulse signal data of the target field area, determine the source pulse change function of different source electromagnetic pulses in the time domain , n represents the number of different source electromagnetic pulses; according to the electromagnetic pulse signal data of the target field area, the source pulse frequency change function of different source electromagnetic pulses in the time dimension sequence is determined ; Source pulse variation function of all source electromagnetic pulses in the target field area and source pulse frequency variation function , forming field pulse characteristic data.

[0035] In order to determine whether the equipment in the field is likely to be affected by electromagnetic pulses, it is necessary to first accurately extract information about the electromagnetic pulses that occur in the field. Considering that the impact of electromagnetic pulses on equipment is mainly due to the large induced current generated by its electromagnetic induction, which damages the electrical components of the equipment, the main features considered when extracting information from electromagnetic pulses are the changes in the amplitude of the electromagnetic pulses over time and the changes in the frequency of the electromagnetic pulses over time. Although the amplitude and frequency are not directly related to the generation of induced current, they play a positively correlated role in the main factors that generate induced current, such as having a certain degree of influence on the magnetic flux, that is, the larger the amplitude, the higher the magnetic flux, and the larger the frequency, the higher the energy density per unit time, that is, the density of the magnetic flux per unit time. At the same time, considering that multiple electromagnetic pulses will be generated in the target field, it is necessary to extract features separately to fully consider the impact of all electromagnetic pulses on the equipment.

[0036] S2: Obtain the anti-pulse performance data of all equipment in the target area, and perform interference analysis in combination with the pulse characteristic data of the area to form equipment interference impact data.

[0037] Obtain the anti-pulse performance data of all equipment in the target area, and combine the pulse characteristic data of the area to perform interference analysis to form equipment interference impact data, including: obtaining the anti-pulse performance data of all equipment in the target area, and according to the source pulse change function corresponding to different source electromagnetic pulses and source pulse frequency variation function , conduct interference analysis of a single pulse source to form interference impact data of a single pulse source; obtain the anti-pulse performance data of all equipment in the target area, and combine the source pulse change function corresponding to different source electromagnetic pulses , conduct pulse source combined interference analysis to form combined pulse source interference impact data; combine single pulse source interference impact data and combined pulse source interference impact data to form equipment interference impact data.

[0038] Of course, whether the electromagnetic pulse affects the performance of the equipment can be accurately determined by extracting the characteristic information of the electromagnetic pulse and comparing it with the electromagnetic pulse range that the equipment can protect. If different electromagnetic pulses occur at the same time, there will be energy superposition. Therefore, when considering whether each electromagnetic pulse affects the performance of the equipment, it is also necessary to consider the situation where the energy superposition of different electromagnetic pulses affects the performance of the equipment. Therefore, the interference analysis of the equipment includes the impact analysis of a single pulse source and the impact analysis of comprehensive multi-source pulses.

[0039] S21: Obtain the anti-pulse performance data of all equipment in the target area, and calculate the source pulse change function according to different source electromagnetic pulses and source pulse frequency variation function , conduct interference analysis of a single pulse source and form interference impact data of a single pulse source, including: obtaining the continuous reception time change function of different devices , where m represents the number of different devices, Indicates the continuous receiving pulse amplitude value corresponding to the device numbered m. , Indicates the acceptable pulse energy range, Indicates the continuous receiving pulse frequency value corresponding to the device numbered m. , Indicates the frequency range of the received pulse; according to the source pulse change function corresponding to different source electromagnetic pulses and source pulse frequency variation function , and combined with the continuous reception duration change function corresponding to different devices , conduct interference analysis and form single pulse source interference impact data.

[0040] For equipment, in order to be able to work stably and continuously in an environment with electromagnetic pulses, it is necessary to carry out a certain degree of electromagnetic pulse protection design. However, this protection has certain limitations and cannot include all possible electromagnetic pulses. Therefore, when analyzing whether electromagnetic pulses have an impact on the equipment, it is necessary to compare and analyze its protection performance information with the characteristic information of all electromagnetic pulses in the field. Here, the electromagnetic pulse protection of the equipment mainly considers the elimination and prevention of the induced current generated by the electromagnetic pulse, and in order to be able to make a reasonable comparison and analysis with the characteristic information of the electromagnetic pulse, the protection performance of the equipment obtained also considers the frequency and amplitude of the electromagnetic pulse that it can protect, and the duration of continuous protection at the corresponding pulse frequency and amplitude. By extracting the protection characteristic information of the equipment in this aspect, it is possible to achieve an accurate and reasonable comparison with the characteristic information of the electromagnetic pulse, and then determine whether the equipment is affected in the electromagnetic pulse environment.

[0041] According to the source pulse variation function corresponding to different source electromagnetic pulses and source pulse frequency variation function , and combined with the continuous reception duration change function corresponding to different devices , conduct interference analysis to form single pulse source interference impact data, including: source pulse change function corresponding to different source electromagnetic pulses , determine the corresponding maximum amplitude , according to the source pulse frequency variation function of different source electromagnetic pulses , determine the maximum amplitude Corresponding amplitude frequency ; According to the maximum amplitude corresponding to electromagnetic pulses from different sources and amplitude frequency , and combined with the continuous reception duration change function corresponding to different devices , the following interference analysis is performed: for any source electromagnetic pulse, if the continuous receiving time variation function The maximum amplitude Equal continuous pulse amplitude values The corresponding minimum acceptance frequency is greater than the amplitude frequency , then there is no single pulse source interference information; for any source electromagnetic pulse, if the continuous reception time variation function Lower and amplitude frequency Equal continuous pulse frequency value The corresponding minimum acceptable amplitude is greater than the maximum amplitude , then there is no single pulse source interference information; for any source electromagnetic pulse, if the continuous reception time variation function The maximum amplitude Equal continuous pulse amplitude values There is a corresponding acceptance frequency and amplitude frequency If they are equal, then according to the source pulse change function and source pulse frequency variation function , determine the maximum amplitude and amplitude frequency Continuous pulse duration: When the pulse duration is not greater than the continuous receiving duration change function The determined reception duration will form a single pulse source interfering with the acceptable information; when the pulse duration is greater than the continuous reception duration variation function The determined reception duration will form a single pulse source continuous interference information; for any source electromagnetic pulse, if the continuous reception duration change function Lower and amplitude frequency Equal continuous pulse frequency value There is a corresponding acceptance amplitude and maximum amplitude If they are equal, then according to the source pulse change function and source pulse frequency variation function , determine the maximum amplitude and amplitude frequency Continuous pulse duration: When the pulse duration is not greater than the continuous receiving duration change function The determined reception duration will form a single pulse source interfering with the acceptable information; when the pulse duration is greater than the continuous reception duration variation function The determined reception duration will form a single pulse source continuous interference information; for any source electromagnetic pulse, if the continuous reception duration change function The maximum amplitude Equal continuous pulse amplitude values The corresponding maximum acceptance frequency is less than the amplitude frequency , then a single pulse source instant interference information is formed; for any source electromagnetic pulse, if the continuous receiving time variation function Lower and amplitude frequency Equal continuous pulse frequency value The corresponding maximum accepted amplitude is less than the maximum amplitude , then a single pulse source instant interference information is formed.

[0042] The impact of a single pulse source on the equipment mainly considers whether the amplitude and frequency of the electromagnetic pulse exceed the acceptable range of the equipment protection. The following situations may occur when comparing the equipment protection feature data with the electromagnetic pulse feature information: one is that the maximum amplitude and frequency of all electromagnetic pulses are smaller than the amplitude and frequency that the equipment needs to protect. In this case, any single electromagnetic pulse will not affect any equipment at all; the second situation is that the maximum amplitude and frequency of all electromagnetic pulses are within the amplitude and frequency range that the equipment needs to protect. This situation indicates that there are some electromagnetic pulses with large amplitudes and frequencies that can affect the equipment, but they are just within the range that the equipment can protect. However, this protection is sometimes not able to continue. Therefore, it is necessary to determine whether the duration of the maximum amplitude and frequency of the electromagnetic pulse is within the corresponding duration of the electromagnetic pulse that the equipment can protect. The third situation is that the maximum amplitude and frequency of all electromagnetic pulses exceed the amplitude and frequency range that the equipment can protect. This situation indicates that the protection of some electromagnetic pulse equipment cannot prevent it from causing damage to the equipment. Different interference situation result information is formed for different comparative analysis situations, thereby providing accurate data reference for subsequent early warning analysis.

[0043] S22: Obtain the anti-pulse performance data of all equipment in the target area, and combine the source pulse change function corresponding to different source electromagnetic pulses , conduct pulse source combined interference analysis to form combined pulse source interference impact data, including: source pulse change function corresponding to different source electromagnetic pulses , perform multi-source energy superposition processing to form a multi-source pulse change function corresponding to the target field area , and according to the multi-source pulse variation function , determine the multi-source pulse comprehensive frequency change function of the target field ; According to the multi-source pulse variation function and multi-source pulse comprehensive frequency variation function , and combined with the continuous reception duration change function corresponding to different devices , conduct combined interference analysis and form combined pulse source interference impact data.

[0044] Different electromagnetic pulses have energy superposition, especially in different electromagnetic pulses with close phases. Since the peaks and troughs of energy are close, there may be positive superposition of energy at the maximum point, thus forming a stronger pulse energy. Therefore, it is necessary to conduct multi-source comprehensive analysis of different electromagnetic pulses. To achieve comprehensive impact analysis of multi-source electromagnetic pulses, it is necessary to merge and analyze different electromagnetic pulse data. There are various ways to merge, such as Fourier transform, direct superposition in the time domain, etc., to finally form combined electromagnetic pulse feature information. Similarly, the combined electromagnetic pulse feature information also considers the two aspects of amplitude and frequency to achieve reasonable and accurate comparative analysis with the protection feature information of the equipment.

[0045] According to the multi-source pulse variation function and multi-source pulse comprehensive frequency variation function , and combined with the continuous reception duration change function corresponding to different devices , conduct combined interference analysis to form combined pulse source interference impact data, including: according to the multi-source pulse change function , determine the maximum integrated amplitude , according to the multi-source pulse comprehensive frequency change function , determine the maximum integrated amplitude The corresponding comprehensive mapping frequency ; For any device, if it continues to receive the duration change function The maximum integrated amplitude Equal continuous pulse amplitude values The corresponding minimum acceptance frequency is greater than the comprehensive mapping frequency , then no combined pulse interference information is formed; for any device, if it continues to receive the time-varying function On and integrated mapping frequency Equal continuous pulse frequency value The corresponding minimum accepted amplitude is greater than the maximum integrated amplitude , then no combined pulse interference information is formed; for any device, if it continues to receive the time-varying function The maximum integrated amplitude Equal continuous pulse amplitude values There is a corresponding continuous pulse frequency value With comprehensive mapping frequency If they are equal, then according to the multi-source pulse variation function and multi-source pulse comprehensive frequency variation function , determine the maximum integrated amplitude and the comprehensive mapping frequency The continuous comprehensive duration: when the comprehensive duration is not greater than the continuous acceptance duration change function The determined reception duration will form a combined pulse that can accept interference information; when the combined duration is greater than the continuous reception duration variation function Determine the reception duration, then form the combined pulse continuous interference information; for any device, if the continuous reception duration change function On and integrated mapping frequency Equal continuous pulse frequency value There is a corresponding continuous receiving pulse amplitude value The maximum integrated amplitude If they are equal, then according to the multi-source pulse variation function and multi-source pulse comprehensive frequency variation function , determine the maximum integrated amplitude and the comprehensive mapping frequency The continuous comprehensive duration: when the comprehensive duration is not greater than the continuous acceptance duration change function The determined reception duration will form a combined pulse that can accept interference information; when the combined duration is greater than the continuous reception duration variation function Determine the reception duration, then form the combined pulse continuous interference information; for any device, if the continuous reception duration change function The maximum integrated amplitude Equal continuous pulse amplitude values The corresponding maximum acceptance frequency is less than the comprehensive mapping frequency , then the combined pulse instant interference information is formed; for any device, if it continuously receives the time-varying function On and integrated mapping frequency Equal continuous pulse frequency value The corresponding maximum accepted amplitude is less than the maximum integrated amplitude , then the combined pulse instant interference information is formed.

[0046] The interference analysis of the combined pulse on the equipment is also determined by comparing the amplitude and frequency of the pulse with the protection characteristics of the equipment. The results of this comparative analysis are as follows: one is that the maximum amplitude and frequency of the combined pulse are less than the minimum amplitude and frequency of any equipment for protection. This situation indicates that the combined effect of all electromagnetic pulses will not affect the equipment. The second is that the maximum amplitude and frequency of the combined pulse are within the range of equipment protection. In this case, it is necessary to determine whether the duration of the maximum amplitude and frequency of the combined pulse exceeds the duration corresponding to the equipment protection. The third situation is that the maximum amplitude and frequency of the combined pulse exceed the range that the equipment can protect. In this case, the combined effect of the electromagnetic pulse directly affects the equipment.

[0047] S23: Collect the interference impact data of the single pulse source and the interference impact data of the combined pulse source to form the equipment interference impact data.

[0048] The impact on the equipment includes the interference from a single pulse source and the interference from a combined pulse source. Both types of analysis data need to be considered and combined together to provide sufficient data reference for subsequent early warning analysis.

[0049] S3: Perform early warning analysis based on the equipment interference impact data to form equipment interference early warning data.

[0050] Perform early warning analysis based on the equipment interference impact data to form equipment interference early warning data, including: obtaining single pulse source interference impact data and combined pulse source interference impact data corresponding to different equipment, and classifying the equipment into early warning types according to different interference categories to form equipment early warning classification result data; based on the equipment early warning classification result data, form different early warning operation prompt information.

[0051] By obtaining the single pulse source interference analysis results and combined pulse source interference analysis results of different devices, the interference type of the device can be located, so as to provide corresponding reasonable early warning information to accurately prompt the situation of the device.

[0052] Obtain the single pulse source interference impact data and the combined pulse source interference impact data corresponding to different devices, and classify the equipment into early warning types according to different interference categories to form equipment early warning classification result data, including: calibrating the single pulse source interference impact data into the following interference categories: calibrating the single pulse source interference information without a single pulse source as a non-warning category, calibrating the single pulse source interference acceptable information as a first-level warning category, calibrating the single pulse source continuous interference information as a second-level warning category, and calibrating the single pulse source immediate interference information as a third-level warning category; calibrating the combined pulse source interference impact data into the following interference categories: calibrating the combined pulse interference information without a combined pulse as a non-warning category, calibrating the combined pulse acceptable interference information as a first-level warning category, calibrating the combined pulse continuous interference information as a second-level warning category, and calibrating the combined pulse immediate interference information as a third-level warning category; for different equipment, determine the highest warning category according to the corresponding single pulse source interference impact data and combined pulse source interference impact data, and use the highest warning category as the equipment warning category corresponding to the equipment; perform unified category clustering according to the equipment warning categories corresponding to different equipment to form different warning equipment sets.

[0053] Regardless of the analysis results of a single pulse source or a combined pulse source, their impact on the equipment is equivalent in the same category. Therefore, when categorizing the equipment, selecting the highest category to which the equipment is subject as the interference level of the equipment can truly reflect the interference situation of the equipment.

[0054] According to the equipment warning classification result data, different warning operation prompt information is formed, including: for the warning equipment set whose warning category is the non-warning category, normal operation information is formed; for the warning equipment set whose warning category is the first-level warning category, inspection and test operation prompt information is formed; for the warning equipment set whose warning category is the second-level warning category, inspection and test operation prompt information is formed; for the warning equipment set whose warning category is the third-level warning category, maintenance operation prompt information is formed.

[0055] Due to the different interference levels of the equipment, the damage caused to the equipment is also different. Especially for the first and second level categories, although the equipment can provide a certain degree of protection, it is still necessary to provide early warning of inspection and testing to determine whether the equipment can work normally. For the third level category, the equipment is definitely not damaged by electromagnetic pulses, so it can directly provide early warning for maintenance.

[0056] The present invention also provides an electromagnetic pulse field data analysis system, which includes a data acquisition unit for acquiring electromagnetic pulse signal data of a target field; a data analysis unit for acquiring the electromagnetic pulse signal data of the target field acquired by the data acquisition unit, and performing feature extraction and interference analysis to form equipment interference impact data; and an early warning unit for acquiring the equipment interference impact data formed by the data analysis unit, performing early warning analysis, and forming equipment interference early warning data.

[0057] In summary, the electromagnetic pulse field data analysis method provided by the embodiment of the present invention has the following beneficial effects: This method collects pulse signal data from the target area and extracts features based on electromagnetic pulse data from different sources to form feature data information of electromagnetic pulses from all sources in the area. Combined with the anti-electromagnetic pulse information of all equipment in the area, the equipment is analyzed to see whether it is interfered with by the electromagnetic pulse. The equipment affected by the electromagnetic pulse can be determined, and early warning information for the equipment can be provided in a timely manner. The affected equipment can be located instantly through the early warning, providing real-time data reference for the equipment operation status, thereby avoiding the adverse effects on normal operation caused by the lack of knowledge of equipment performance degradation or failure.
