Through the analysis of the meteorological effect value, obtain the analysis result, and predict the meteorological monitoring data according to the analysis result to obtain meteorological prediction data;
[0045] S4. Generate a warning signal and a regional warning plan according to the meteorological prediction data and the analysis result.
[0046] It should be further noted that in the specific implementation process, the process of collecting meteorological station data and the drone detection area, setting up a drone monitoring group, constructing a drone monitoring network, and collecting flow condition data through the meteorological station data and the drone detection area is as follows:
[0047] The meteorological station information includes the positioning information of the meteorological station and the monitoring area of the meteorological station; the meteorological station corresponding to the meteorological station positioning information is denoted as a meteorological point, and it is stipulated that the meteorological point is at the center of the meteorological monitoring area; the meteorological station monitoring area refers to the monitoring areas corresponding to each meteorological point; the UAV detection area refers to the fixed monitoring range of the UAV.
[0048] Process the meteorological station monitoring area through the UAV detection area, reduce the UAV detection area proportionally until n equally scaled-down UAV detection areas exactly cover the meteorological station monitoring area completely. Then divide the meteorological station monitoring area into n areas, denoted as meteorological monitoring areas, and n is a positive integer. Then the UAV monitoring group consists of n UAVs. The UAVs are placed in each meteorological monitoring area, and monitoring links and transmission links are respectively constructed between adjacent UAVs within the meteorological monitoring area and between the UAVs and the meteorological points. Through the UAVs, meteorological points, monitoring links, and transmission links, a UAV monitoring network is constructed, and an Internet of Things center is set up within the meteorological points. The Internet of Things center is used to collect and collate the monitoring data of the meteorological monitoring area; the flow situation data includes the biological flow time and the biological flow quantity; the biological flow quantity refers to the quantity of organisms with a living state and generating life activities, including the animal flow quantity and the human flow quantity; the biological flow time refers to the time corresponding to the organisms with a living state when generating life activities.

[0050] The flight record height refers to the recorded flight height of the UAV during monitoring within the meteorological monitoring area.
[0051] Set the recorded flow density. The recorded flow density is the biological flow density of the meteorological monitoring area corresponding to the flight record height. According to the biological flow time, biological flow quantity, flight record height, and recorded flow density, obtain the meteorological monitoring value Qx t ;
[0052]
[0053] Among them, α1 and α2 are the weights of the animal flow quantity and the human flow quantity; d t is the animal flow quantity; r t is the human flow quantity; H is the recorded flight height; S is the area of the meteorological monitoring area; M is the recorded flow density; t is the biological flow time; Qx t refers to the meteorological monitoring value corresponding to the biological flow time.
[0054] Based on the meteorological monitoring values, the flight altitudes of the unmanned aerial vehicles (UAVs) within the meteorological monitoring area are adjusted to the meteorological monitoring values. After the adjustment of the UAVs is completed, the meteorological monitoring data of the meteorological monitoring area is collected, and the meteorological historical data of the UAVs within the meteorological monitoring area is obtained. The meteorological historical data includes temperature historical values, precipitation historical values, wind speed historical values, and historical monitoring times, and the meteorological index data of the meteorological historical data is obtained.

For meteorological monitoring data, the meteorological situation corresponding to the meteorological index data is known information; in the calculation process of the meteorological effect value, normalization processing has been carried out;
[0064] Analyze the meteorological effect value. When the meteorological effect value is equal to 0, the meteorological situation in the meteorological monitoring area is normal, and analysis result one is generated;
[0065] When the meteorological effect value is not equal to 0, set the meteorological effect standard value. When the meteorological effect value is greater than or equal to the meteorological effect standard value, the meteorological situation in the meteorological monitoring area is abnormal, and analysis result two is generated; when the meteorological effect value is less than the meteorological effect standard value, the meteorological situation in the meteorological monitoring area is normal, and analysis result three is generated;
[0066] When analysis result one or analysis result two or analysis result three is generated, obtain the meteorological historical data corresponding to analysis result one or analysis result two or analysis result three, perform corresponding difference calculations on the temperature historical value, precipitation historical value, and wind speed historical value of the meteorological historical data in adjacent historical orders, obtain the historical temperature change amplitude, historical precipitation fluctuation value, and historical wind speed mutation value, and record the historical temperature change amplitude, historical precipitation fluctuation value, and historical wind speed mutation value as the meteorological historical change value;
[0067] Use several groups of meteorological historical change values and historical monitoring times as the training set and test set, input the training set and test set into the meteorological prediction model, train the meteorological prediction model, obtain the trained meteorological prediction model, and output the corresponding meteorological prediction data.

[0068] It should be further noted that in the specific implementation process, the process of generating warning signals and regional warning plans based on the meteorological prediction data and analysis results is as follows:
[0069] Obtain the meteorological prediction value of the meteorological monitoring area according to the meteorological prediction data of the meteorological monitoring area;
[0070] The predicted temperature variation amplitude, predicted precipitation fluctuation value, and predicted wind speed mutation value of meteorological prediction data are weighted with the temperature influence coefficient, precipitation influence coefficient, and wind speed influence coefficient to obtain a meteorological prediction value; a meteorological region coefficient is set, where the meteorological region coefficient refers to the influence coefficient of the meteorological prediction degree of a meteorological monitoring region on other meteorological monitoring regions, and the meteorological region coefficient of the meteorological monitoring region is weighted with the meteorological prediction value to obtain a meteorological region value;
[0071] It should be further noted that in the specific implementation process, during the calculation of the meteorological region value, the meteorological region coefficient and the meteorological prediction value have been normalized;
[0072] A meteorological standard region value is set; when only analysis result one and analysis result three are generated in the meteorological station monitoring region, if the meteorological region value is greater than or equal to the meteorological standard region value, warning signal one is generated; when analysis result two is generated in the meteorological station monitoring region, if the meteorological region value is less than the meteorological standard region value, warning signal two is generated; when analysis result two is generated in the meteorological station monitoring region, if the meteorological region value is greater than or equal to the meteorological standard region value, warning signal three is generated; when only analysis result one and analysis result three are generated in the meteorological station monitoring region, if the meteorological region value is less than the meteorological standard region value, a monitoring signal is generated; warning signal one or warning signal two or warning signal three is sent to the Internet of Things center, and the Internet of Things center sends warning signal one or warning signal two or warning signal three to the relevant meteorological warning personnel to generate a regional warning plan.
