DETAILED DESCRIPTION

[0044] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0045] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the drawings in the embodiments of the present application are collected below to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] An embodiment of the present application provides a satellite-based extreme weather monitoring method, which can be executed by an electronic device, wherein the electronic device can be a server, wherein the server can be an independent physical server, or a server cluster or distributed device composed of multiple physical servers, or a cloud server that provides cloud computing services; the server can be installed on a ground communication terminal or on a satellite.

[0047] Reference Figure 1 , a satellite-based extreme weather monitoring method includes: step S101, step S102 and step S103, wherein,

[0048] S101, determining extreme weather data of a first area of ​​a target area corresponding to a first target satellite and acquiring satellite data of the first target satellite.

[0049] In some embodiments, the satellite data includes a first operation period.

[0050] When the first target satellite moves to the target area, it monitors the clouds and other weather conditions in the target area and obtains the weather data of the target area; the electronic device obtains the weather data from the first target satellite, analyzes the weather data and compares it with the historical weather data, so as to determine the extreme weather data contained in the weather data, wherein the extreme weather data may be extreme weather data such as extreme rain and snow, hail and strong wind; at the same time, the electronic device sends a satellite data acquisition instruction to the first target satellite, and sends the instruction to the first target satellite, the first target satellite responds to the instruction and sends the satellite data to the electronic device, and the electronic device uses the satellite data as reference data for finding other satellites for weather monitoring of the target area.

[0051] S102, when the meteorological type of the extreme meteorological data in the first region is a preset meteorological type, the meteorological type is substituted into a preset meteorological monitoring specification database to determine a meteorological monitoring period corresponding to the extreme meteorological data in the first region.

[0052] In some embodiments, different types of extreme weather have different degrees of impact and speed of change. If different meteorological monitoring cycles are used to monitor different types of extreme weather data, it is easy for the weather to change too quickly and be monitored untimely, thus affecting the authenticity of the meteorological monitoring. Therefore, after obtaining the extreme weather data of the first area, the electronic device can determine the meteorological monitoring cycle that is suitable for the meteorological type of the extreme weather data of the first area, that is, the electronic device performs data analysis on the extreme weather data of the first area, determines the meteorological type corresponding to the extreme weather data of the first area, and then determines whether the meteorological type is a preset meteorological type.

[0053] When the electronic device determines that the meteorological type of the extreme meteorological data in the first area is a preset meteorological type, it indicates that it is necessary to determine the meteorological monitoring period of the extreme meteorological data in the first area. Subsequently, the electronic device substitutes the meteorological type into the preset meteorological monitoring specification database based on a preset meteorological monitoring specification database constructed in advance, and filters out the meteorological monitoring period corresponding to the extreme meteorological data in the first area from the preset meteorological monitoring specification database.

[0054] S103, when the meteorological monitoring period is less than the first operation period, determining a second target satellite based on the satellite data and the first operation period, and generating a meteorological monitoring instruction;

[0055] S104, based on the meteorological monitoring instruction, controlling the second target satellite to perform meteorological monitoring on the target area.

[0056] In some embodiments, the first target satellite and the second target satellite are low-orbit satellites; the first operation cycle is the duration between the current arrival time of the first target satellite at the target area and the next arrival time at the target area. The electronic device determines whether the meteorological monitoring cycle is less than the first operation cycle, and if it is determined that the meteorological monitoring cycle is less than the first operation cycle, it indicates that the meteorological changes of the extreme meteorological data in the first area are fast, and the first target satellite cannot meet the monitoring of the extreme meteorological data in the first area in the target area based on the first operation cycle. Therefore, it is necessary to use other satellites for simultaneous monitoring while monitoring the first target satellite; then, the electronic device determines the second target satellite based on the satellite data and the first operation cycle of the first target satellite.

[0057] The electronic device generates a meteorological monitoring instruction and sends the meteorological monitoring instruction to the second target satellite, controls the second target satellite to respond to the meteorological monitoring instruction, and performs meteorological monitoring on the target area when the second target satellite arrives at the target area, and sends the acquired meteorological data including extreme meteorological data in the area to the electronic device; thereby improving the accuracy of extreme meteorological monitoring in the target area.

[0058] In some embodiments, the first-region extreme weather data includes extreme weather data and first extreme weather change data; then in step S101, the first-region extreme weather data of the target region corresponding to the first target satellite is determined, including: obtaining at least two sets of initial weather data of the target region corresponding to the first target satellite, wherein the at least two sets of initial weather data are respectively weather data monitored by the first target satellite in adjacent and different operating cycles; determining the regional extreme weather data corresponding to the at least two sets of initial weather data, and comparing the at least two regional extreme weather data to obtain the first extreme weather change data, and integrating the at least two regional extreme weather data and the first extreme weather change data to obtain the first regional extreme weather data.

[0059] In some embodiments, the electronic device obtains initial meteorological data of the monitored target area during at least two adjacent and different operating cycles from the first target satellite, and determines the regional extreme meteorological data contained in the initial meteorological data obtained during each operating cycle; then, the electronic device compares at least two regional extreme meteorological data to determine the first extreme meteorological change data between the two first regional extreme meteorological data of adjacent operating cycles; the electronic device integrates at least two first regional extreme meteorological data and the first extreme meteorological change data to obtain the first regional extreme meteorological data.

[0060] In some embodiments, when the electronic device compares the extreme data of at least two regions, it compares the cloud data and airflow data contained in the extreme meteorological data of at least two regions respectively, determines the change data corresponding to the cloud data and the airflow data, and integrates the corresponding change data to obtain the first extreme meteorological change data.

[0061] In step S102, a preset meteorological monitoring specification database is constructed by the following steps: obtaining multiple groups of historical meteorological data, wherein the multiple groups of historical meteorological data are meteorological data monitored during different historical meteorological weather conditions; determining the historical extreme meteorological data corresponding to the multiple groups of historical meteorological data and their corresponding meteorological types; based on the meteorological type, determining the meteorological level, meteorological change data and meteorological impact degree corresponding to the historical extreme meteorological data; based on the meteorological level, meteorological change data and meteorological impact degree, determining the meteorological monitoring period corresponding to the historical extreme meteorological data; constructing a preset meteorological monitoring specification database from the historical extreme meteorological data, meteorological level, meteorological change data, meteorological impact degree and meteorological monitoring period.

[0062] In some embodiments, the electronic device obtains historical meteorological data characterized by monitoring at different historical meteorological weather conditions from a storage device installed in a meteorological monitoring station, and analyzes multiple groups of historical meteorological data to determine the historical extreme meteorological data and the corresponding meteorological type contained in each group of historical meteorological data. The historical extreme meteorological data contains at least two types of extreme meteorology, and the electronic device obtains the meteorological level, meteorological change data, and meteorological impact degree corresponding to each type of extreme meteorology from the historical extreme meteorological data based on the meteorological type.

[0063] Meteorological type, meteorological level, meteorological change data, and meteorological impact degree can all reflect the impact degree of the corresponding extreme weather. Therefore, the electronic device can determine the meteorological monitoring period corresponding to the historical extreme weather data based on the meteorological type, meteorological level, meteorological change data, and meteorological impact degree. Among them, the technicians can use the electronic device to classify the meteorological type, meteorological level, meteorological change data, and meteorological impact degree in advance; for example, the meteorological type can be divided into three levels: emergency, secondary emergency, and non-emergency; the meteorological level is set to the first meteorological level, the second meteorological level, and the third meteorological level; the meteorological change data is set to the first change range, the second change range, and the third change range; the meteorological impact degree is set to the first impact degree, the second impact degree, and the third impact degree; and based on the above-mentioned divided levels, the corresponding meteorological monitoring period is set. The electronic device selects the meteorological monitoring period that meets its requirements based on the determined meteorological type, meteorological level, meteorological change data, and meteorological impact degree; then, the electronic device integrates the historical extreme weather data, meteorological level, meteorological change data, meteorological impact degree, and meteorological monitoring period to construct a preset meteorological monitoring specification database.

[0064] In some embodiments, the satellite data includes a first time when the first target satellite arrives at the target area; then in step S103, based on the satellite data and the first operating cycle, the second target satellite is determined, including: obtaining the second operating cycle of multiple initial satellites and the second time of arrival at the target area; based on the second operating cycle, selecting multiple alternative satellites with the same operating cycle as the first operating cycle from the multiple initial satellites; based on the second time corresponding to the multiple alternative satellites and the first time, selecting the second target satellite from the multiple alternative satellites.

[0065] In some embodiments, the operating altitudes of multiple initial satellites are equal to reduce the difference in accuracy of the meteorological data monitored due to different satellite operating altitudes; the second operating cycle is the time it takes for the initial satellite to orbit the earth.

[0066] The electronic device obtains the second operating period of the initial satellite and the second time when each initial satellite respectively operates to the target area. Subsequently, the electronic device compares the multiple second operating periods obtained with the first operating period, retains the initial satellites with the second operating period equal to the first operating period, and eliminates the initial satellites with the second operating period not equal to the first operating period, thereby selecting multiple candidate satellites from the multiple initial satellites; subsequently, the electronic device compares the second time with the first time, and when the second time satisfies a preset relationship with the first time, defines the candidate satellite corresponding to the second time as the second target satellite.

[0067] In some embodiments, the first time includes a first sub-time and a second sub-time; based on the second time corresponding to the multiple candidate satellites and the first time, a second target satellite is selected from the multiple candidate satellites, including: determining a time range based on the first sub-time and the second sub-time; judging whether the second time corresponding to the multiple candidate satellites is within the time range; and taking the candidate satellite corresponding to the second time within the time range as the second target satellite.

[0068] In some embodiments, the first sub-time is the time when the first target satellite arrives at the target area for the first time, and the second sub-time is the time when the first target satellite arrives at the target area for the second time.

[0069] The electronic device subtracts the second sub-time from the first sub-time to determine a time range, and the time range is equal to the first operation period of the first target satellite; the electronic device adjusts the second times corresponding to the plurality of candidate satellites into the time range, and determines whether the second time is within the time range. When the electronic device determines that the second time of any candidate satellite is within the time range, the electronic device defines any candidate satellite as the second target satellite.

[0070] In some embodiments, an alternative satellite corresponding to a second time within a time range is used as a second target satellite, including: when there are at least two alternative satellites among multiple alternative satellites whose corresponding second times are within the time range, determining a midpoint time based on a first sub-time and a second sub-time; comparing the second times corresponding to the at least two alternative satellites with the midpoint time respectively to determine at least two time differences; and using the alternative satellite corresponding to the smallest time difference among the at least two time differences as the second target satellite.

[0071] In some embodiments, when the electronic device determines that the second times of at least two candidate satellites among multiple candidate satellites are within the time range, it indicates that the at least two candidate satellites meet the conditions for meteorological monitoring of the target area. However, considering the balance of the monitoring period of meteorological monitoring of the target area, a more suitable candidate satellite can be selected from the at least two candidate satellites, that is, the electronic device first determines the midpoint time between the first sub-time and the second sub-time, for example, the first time is 11 o'clock and the second time is 12 o'clock, then the midpoint time is 11.30 o'clock, and then the electronic device compares the second times corresponding to the at least two candidate satellites with the midpoint time respectively, and determines the absolute difference between the second time and the midpoint time, that is, the time difference; then, compares the at least two time differences, and takes the candidate satellite corresponding to the smallest time of the at least two time differences as the second target satellite; thereby improving the balance between the meteorological monitoring periods for the target area.

[0072] In step S104, after controlling the second target satellite to perform meteorological monitoring on the target area, it also includes: obtaining the extreme meteorological data of the second area corresponding to the second target satellite; determining the second extreme meteorological change data of the target area based on the extreme meteorological data of the first area and the extreme meteorological data of the second area; and generating an additional satellite meteorological monitoring instruction when the second extreme meteorological change data is greater than the preset extreme meteorological change data.

[0073] In some embodiments, after the electronic device controls the second target satellite to perform meteorological monitoring on the target area, it obtains the extreme meteorological data of the second area corresponding to the target area from the second target satellite; and compares the extreme meteorological data of the first area with the extreme meteorological data of the second area to obtain the second extreme meteorological change data of the target area. Subsequently, the electronic device compares the second extreme meteorological data with the preset extreme meteorological change data to determine whether the second extreme meteorological data is greater than the preset extreme meteorological change data. When the electronic device determines that the second extreme meteorological change data is greater than the preset extreme meteorological change data, it indicates that the change of extreme meteorology in the target area is further accelerated, and the period of monitoring the extreme meteorological data of the target area needs to be shortened. Then, the electronic device generates an additional meteorological monitoring instruction, and sends the additional meteorological monitoring instruction to the target medium and high orbit satellite, and controls the target medium and high orbit satellite to perform meteorological monitoring on the target area.
