[0068] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0069] Refer to Figure 1 , a lightning monitoring and warning method, including:

[0070] S1. Obtain a preset warning area, and monitor the atmospheric electric field information of the preset warning area. The atmospheric electric field information includes time information and the environmental electric field value corresponding to the time information;

[0071] As described in the above embodiment, the background system obtains the preset warning area. The preset warning area can be a lightning monitoring, warning and warning area preset by the user. Then, the background system obtains the atmospheric electric field information in the preset warning area. The atmospheric electric field information includes the time information and the environmental electric field value expected to match the event information. Specifically, the environmental electric field value is correspondingly matched with a time tag consistent with the monitoring time. Then, the background system obtains the environmental electric field value with the time tag and integrates it into the atmospheric electric field information.

[0072] Among them, the background system can be an independent server or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (CDNs), and big data and artificial intelligence platforms. The present invention does not limit this.

[0073] S2. Perform an execution information interception step, where the execution information interception step includes intercepting the environmental electric field value according to a first preset duration to generate a monitored electric field value.

[0074] As described in step S2 above, the background system executes a preset information interception step. The information acquisition step is: obtaining a first preset duration, and acquiring the environmental electric field value corresponding to the duration according to the first preset duration and the time information, and recording it as the monitored electric field value. In this embodiment, the first preset duration is 30 minutes. Then, the background system acquires the environmental electric field value of the preset warning area within 30 minutes in a 30 - minute time period and records it as the monitored electric field value.

[0075] S3. Determine whether the monitored electric field value is higher than a preset warning threshold.

[0076] As described in step S3 above, the background system acquires the preset warning threshold and determines whether the monitored electric field value is higher than the preset warning threshold. If the background system determines that the monitored electric field value is lower than the preset warning threshold, then the background system determines that the weather condition of the preset warning area will not change to a thunderstorm weather. When the background system determines that the monitored electric field value is higher than the preset warning threshold, then the background system determines that the weather condition of the preset warning area may change to a thunderstorm weather, and then proceeds to the next step.

[0077] S4. If so, obtain the historical weather information of the preset warning area and calculate the monitored electric field amplitude of the preset warning area according to the historical weather information.

[0078] As described in step S4 above, the background system acquires the historical weather information of the preset warning area. The historical weather information is the historical weather change of the preset warning area. In this embodiment, the weather change is thunderstorm weather or non - thunderstorm weather. Then, the background system calculates the monitored electric field amplitude of the preset warning area according to the thunderstorm weather or the non - thunderstorm weather. The monitored electric field amplitude is used to limit the range of the monitored electric field value.

[0079] S5. Determine whether the monitored electric field value falls within the monitored electric field amplitude.

[0080] As described in step S5 above, the background system matches the monitored electric field value with the monitored electric field amplitude to determine whether the preset warning area is in a thunderstorm. It can be understood that the monitored electric field amplitude can be set by the user himself to distinguish the weather conditions of the preset warning area according to the monitored electric field value. The present invention does not limit the specific value of the monitored electric field amplitude.

[0081] S6. If not, obtain a second preset duration, replace the second preset duration with the first preset duration, and then go to the information interception step.

[0082] As described in step S6 above, when the background system determines that the monitored electric field value does not fall within the monitored electric field amplitude, the background system obtains the second preset duration, replaces the second preset duration with the first preset duration, and then re-executes the information interception step. In this embodiment, the second preset duration is 10 minutes. After the background system determines that the monitored electric field value does not fall within the monitored electric field amplitude, the background system re-obtains the environmental electric field value of the preset warning area within 10 minutes in a 10-minute time period and updates the monitored electric field value, so as to achieve the function of circular monitoring and early warning of the atmospheric electric field information of the preset warning area.

[0083] In this embodiment, through the above method, by obtaining the current atmospheric electric field information of the preset warning area, calculating the monitored electric field amplitude of the preset warning area when a thunderstorm occurs according to the historical weather information of the preset warning area, and finally determining whether the atmospheric electric field information falls within the monitored electric field amplitude. If not, the thunderstorm weather conditions of the preset warning area are monitored by circularly monitoring the preset warning area, which solves the problem that most of the existing thunderstorm weather monitoring methods in the prior art give early warnings based on the thresholds of atmospheric electric field intensity and electric field change rate. The thresholds of these parameters often change greatly due to terrain influence, resulting in inaccurate and untimely data obtained during thunder and lightning early warning, and causing the monitoring accuracy to decrease due to data distortion when the system performs thunder and lightning monitoring and early warning for a specific area, and improves the accuracy of thunder and lightning monitoring and early warning.

[0084] In one embodiment, the historical weather information includes non-thunderstorm weather, and the monitored electric field amplitude includes non-thunderstorm electric field amplitude.

[0085] Then step S4 specifically includes:

[0086] S41. Obtain the first historical electric field information of the preset warning area during non-thunderstorm weather. The first historical electric field information includes a non-thunderstorm duration consistent with the duration of the first preset duration and a non-thunderstorm electric field value corresponding to the non-thunderstorm duration. Calculate the non-thunderstorm electric field amplitude matching the non-thunderstorm weather based on the non-thunderstorm duration and the non-thunderstorm electric field value.

[0087] As described in the above embodiment, the background system obtains the first historical electric field information of the preset warning area during non-thunderstorm weather. The first historical electric field information includes the non-thunderstorm duration consistent with the duration of the first preset duration and the non-thunderstorm electric field value corresponding to the non-thunderstorm duration. When the duration of the first preset duration is 30 minutes, the non-thunderstorm duration is also 30 minutes. The first historical electric field information is the non-thunderstorm electric field value obtained by intercepting the preset warning area at 30-minute time nodes during non-thunderstorm weather. Then, the background system calculates the non-thunderstorm electric field amplitude matching the non-thunderstorm weather based on the non-thunderstorm duration (i.e., 30 minutes consistent with the first preset duration) and the non-thunderstorm electric field value.

[0088] In one embodiment, calculating the non-thunderstorm electric field amplitude matching the non-thunderstorm weather based on the non-thunderstorm duration and the non-thunderstorm electric field value specifically includes:

[0089] S42. Perform empirical mode decomposition on the first historical electric field information to form several non-thunderstorm intrinsic mode components. Perform Hilbert transform on the non-thunderstorm intrinsic mode components to form first amplitude distribution data matching the non-thunderstorm intrinsic mode components. Obtain the first high-frequency amplitude distribution data among the first amplitude distribution data, and record the proportion information of the high-frequency energy in the first high-frequency amplitude distribution data as the non-thunderstorm electric field amplitude.

[0090] As described in the above embodiment, if the non-thunderstorm duration is from 9:00 to 9:30, the background system performs empirical mode decomposition on the first historical electric field information to form 6 non-thunderstorm intrinsic mode components, namely the first IMF1 to the first IMF6. The generation result is as follows: Figure 4 shown:

[0091] Then, the background system performs Hilbert transform on the 6 non-thunderstorm intrinsic mode components, namely the first IMF1 to the first IMF6, to form first amplitude distribution data matching the non-thunderstorm intrinsic mode components. The first amplitude distribution data after Hilbert transform is specifically shown as follows: Figure 5 shown:

[0092] Afterwards, the background system obtains the first high-frequency amplitude distribution data (i.e., the first IMF1) among the first amplitude distribution data, and records the proportion information of the high-frequency energy in the first high-frequency amplitude distribution data (i.e., the first IMF1) as the non-thunderstorm electric field amplitude.

[0093] In one embodiment, the historical weather information further includes thunderstorm weather, and the monitored electric field amplitude further includes the thunderstorm electric field amplitude;

[0094] Then, step S4 further includes:

[0095] S43. Obtain the second historical electric field information of the preset warning area before it becomes the thunderstorm weather. The second historical electric field information includes a thunderstorm preparation duration consistent with the first preset duration and a thunderstorm preparation electric field value corresponding to the thunderstorm preparation duration, and calculate the thunderstorm electric field amplitude matching the thunderstorm weather based on the thunderstorm preparation duration and the thunderstorm preparation electric field value.

[0096] As described in the above embodiment, the background system obtains the second historical electric field information of the preset warning area before it becomes the thunderstorm weather. The second historical electric field information includes the thunderstorm preparation duration consistent with the first preset duration and the thunderstorm preparation electric field value corresponding to the thunderstorm preparation duration. When the first preset duration is 30 minutes, the thunderstorm preparation duration is also 30 minutes. Then, the second historical electric field information is the thunderstorm preparation electric field value obtained by intercepting at the time node 30 minutes before the preset warning area becomes the thunderstorm weather. Afterwards, the background system calculates the thunderstorm electric field amplitude matching the thunderstorm weather based on the thunderstorm preparation duration (i.e., 30 minutes consistent with the first preset duration) and the thunderstorm preparation electric field value.

[0097] In one embodiment, the step of calculating the thunderstorm electric field amplitude matching the thunderstorm weather based on the thunderstorm preparation duration and the thunderstorm preparation electric field value specifically includes:

[0098] S44. Perform empirical mode decomposition on the second historical electric field information to form a number of thunderstorm intrinsic mode components, perform Hilbert transform on the thunderstorm intrinsic mode components, thereby forming second amplitude distribution data matching the thunderstorm intrinsic mode components, obtain the second high-frequency amplitude distribution data among the second amplitude distribution data, and record the proportion information of the high-frequency energy in the second high-frequency amplitude distribution data as the thunderstorm electric field amplitude.

[0099] As described in the above embodiments, if the non-thunderstorm duration is from 19:40 to 20:10, the background system performs classical mode decomposition on the second historical electric field information to form eight thunderstorm intrinsic mode components, namely the second IMF1 to the second IMF8, and the generation result is as Figure 6 shown:

[0100] After that, the background system performs Hilbert transform on the eight thunderstorm intrinsic mode components, namely the second IMF1 to the second IMF8, to form second amplitude distribution data matching the thunderstorm intrinsic mode components. The second amplitude distribution data after the Hilbert transform is specifically shown as Figure 7 shown:

[0101] After that, the background system obtains the second high-frequency amplitude distribution data (i.e., the second IMF1) in the second amplitude distribution data, and records the proportion information of the high-frequency energy in the second high-frequency amplitude distribution data (i.e., the second IMF1) as the thunderstorm electric field amplitude.

[0102] In one embodiment, after step S5, the following steps are further included:

[0103] S51. If so, determine whether the monitored electric field value falls within the non-thunderstorm electric field amplitude. If so, obtain the second preset duration, replace the second preset duration with the first preset duration, and then go to the information interception step.

[0104] As described in the above embodiments, the background system matches the monitored electric field value with the monitored electric field amplitude. When the background system determines that the monitored electric field value exists in the monitored electric field amplitude, the background system matches the monitored electric field value with the non-thunderstorm electric field amplitude again, and determines whether the monitored electric field value falls within the non-thunderstorm electric field amplitude. If so, the background system obtains the second preset duration, replaces the second preset duration with the first preset duration, and then re-executes the information interception step; in this embodiment, the second preset duration is 10 minutes. After the background system determines that the monitored electric field value does not fall within the non-thunderstorm electric field amplitude, the background system re-obtains the environmental electric field value of the preset warning area within 10 minutes in a 10-minute time period and updates the monitored electric field value.

[0105] In one embodiment, after step S5, the following steps are further included:

[0106] S52. If so, determine whether the monitored electric field value falls within the thunderstorm electric field amplitude. If so, obtain the thunderstorm warning information matching the thunderstorm electric field amplitude. The thunderstorm warning information includes a warning range and a warning signal matching the warning range. Determine whether the monitored electric field value falls within the warning range. If so, calculate the high-frequency component energy ratio of the monitored electric field value using HHT transform, denoted as the matching ratio. Determine whether the matching ratio is higher than the preset threshold value. If so, send the warning signal.

[0107] As described in the above embodiment, the background system matches the monitored electric field value with the monitored electric field amplitude. When the background system determines that the monitored electric field value exists in the monitored electric field amplitude, the background system matches the monitored electric field value with the thunderstorm electric field amplitude again. Specifically, the background system obtains the thunderstorm warning information matching the thunderstorm electric field amplitude. The thunderstorm warning information includes several warning ranges and the warning signals matching the corresponding warning ranges. The corresponding relationship between the warning range and the warning signal can be shown in the following table:

[0108]

[0109] Wherein, the E(t) is the monitored electric field value, and a, b, and c are the preset range thresholds.

[0110] Then the background system determines whether the monitored electric field value falls into any of the warning ranges. If so, perform HHT transform calculation on the monitored electric field value to calculate the high-frequency component energy ratio of the monitored electric field value. Then the background system obtains the preset threshold value and determines whether the matching ratio is higher than the preset threshold value. If so, send the warning signal matching the warning range into which the monitored electric field value falls, thereby realizing the function of lightning warning.

[0111] It can be understood that the preset threshold value can be set by the user according to the altitude of the preset warning area. The specific value of the preset threshold value is not limited in the present invention.
