[0041] Figure 3 This is a schematic diagram of the structure of the meteorological disaster early warning device for specific areas provided by the present invention. Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0043] The following is combined with Figures 1-3 This invention describes a method, apparatus, storage medium, and program product for early warning of meteorological disasters in specific areas.

[0044] Figure 1 This is one of the flowcharts illustrating the meteorological disaster early warning method for specific areas provided by this invention, such as... Figure 1 As shown, the method includes the following:

[0045] Step 100: Determine the regional type and regional meteorological data of the area to be processed;

[0046] Specifically, the area to be processed refers to the area requiring meteorological forecasting. In this embodiment, the area type refers to the density of population activity within the area to be processed. Therefore, the area type can be divided into densely populated areas and sparsely populated areas. This embodiment mainly describes a specific area early warning method for meteorological disasters in densely populated areas. The area type can be obtained through communication operator data or by acquiring regional population heat maps, etc. The regional meteorological data of the area to be processed can be obtained through a meteorological forecasting model. The regional meteorological data can include meteorological information for a future period of time within the area to be processed, including weather type, temperature, humidity, and other data.

[0047] Step 200: Determine meteorological disaster information based on the regional meteorological data;

[0048] Specifically, based on the determined regional meteorological data, the data is analyzed (using meteorological forecasting models) to obtain the meteorological conditions of the area to be processed in the future. If meteorological disasters are likely to occur in the area in the future, meteorological disaster information including disaster details is generated. For example, if a certain area to be processed may experience heavy to torrential rain in the next day, with short-term rainfall exceeding the area's drainage capacity, and if the area is urban, it may experience urban flooding. The generated meteorological disaster information could include the rainfall intensity at different times, the rainfall amount at different times, the areas where meteorological disasters may occur, the meteorological disaster risk level, and the possible timing of the meteorological disasters.

[0049] Step 300: If the region type is a dense region, determine the first precision region grid within the region to be processed;

[0050] Specifically, when the area to be processed is determined to be a densely populated area, a region grid division precision is first initialized, and then verified. The verification method is mainly as follows: whether the number of communication devices in a single grid divided based on this precision exceeds a preset threshold. The number of communication devices largely determines the number of people in the grid, and the two are roughly proportional. If the threshold is exceeded, the grid still needs to be further divided, that is, the grid division precision is increased and the grid area is reduced. If the region grid obtained based on the initialized region grid division precision does not have the above verification condition, then the initialized region grid is used as the first precision region grid in this embodiment.

[0051] Step 400: Send a meteorological disaster warning containing the disaster-bearing entity and the meteorological disaster information to the receiving device corresponding to the first precision area grid; the disaster-bearing entity is the location in the area to be processed that responds to the meteorological disaster.

[0052] Specifically, in this embodiment, the disaster-bearing entity refers to the entity within the area to be processed that can bear disasters. The disaster-bearing entity can be certain locations within the area to be processed that are capable of responding to meteorological disasters. After determining the first-precision area grid within the area to be processed, a meteorological disaster warning is sent to the receiving device corresponding to the first-precision area grid. The warning content includes the disaster-bearing entity and meteorological disaster information, so that the receiving device corresponding to the first-precision area grid can receive a more accurate meteorological disaster warning.

[0053] The application uses digital twin technology to output in real time the areas to be processed as defined in this application, including the types of areas, meteorological disaster information corresponding to each area, and area grids of different precision.

[0054] This embodiment determines the region type and regional meteorological data associated with the area to be processed, and determines meteorological disaster information based on the regional meteorological data. In the case of a densely populated region, a first-precision region grid matching it is determined within the area to be processed. Then, a meteorological disaster warning containing information about the disaster-bearing entity and meteorological disaster is sent to the receiving device corresponding to the first-precision region grid. The disaster-bearing entity is determined through the area to be processed. This application improves the accuracy of meteorological disaster warnings for specific regions by associating meteorological disaster information with a region grid of a certain precision, thus precisely delivering meteorological disaster warnings to different regions.

[0055] In one embodiment, the meteorological disaster early warning method for a specific area provided in this application may further include:

[0056] Step 500: If the region type is a sparse region, determine the second precision region grid within the region to be processed; the grid division precision of the second precision region grid is less than that of the first precision region grid.

[0057] Step 600: Send a meteorological disaster warning containing the meteorological disaster information to the receiving subject corresponding to the second precision area grid.

[0058] Specifically, based on the above, the regions to be processed also include sparse regions, such as sparsely populated mountainous areas and remote villages. The division of sparse regions does not necessarily have to be based on data from telecommunications operators, because the population in sparse regions is small, and the data from telecommunications operators is not accurate enough; basic regional planning can be used instead. This division of sparse regions can reduce the amount of data processed, saving computing resources for data processing in densely populated areas.

[0059] Therefore, when the region type is a sparse region, the region to be processed is divided into raster grids with the second precision to obtain the second precision region raster within the region to be processed. The raster grid division precision of the second precision region raster is less than that of the first precision region raster. The higher the raster division precision, the larger the amount of data to be processed.

[0060] If a meteorological disaster is expected in the area to be processed in the near future, the receiving entity corresponding to the second-precision grid area is first identified, and then a meteorological disaster warning containing meteorological disaster information is sent to the receiving entity. This receiving entity can be a resident population within the area to be processed (determined through communication equipment) or pre-set personnel (also determined through pre-set communication equipment). The purpose of identifying the receiving entity is to deliver meteorological disaster information in a timely and effective manner. In cases of severe meteorological disasters, the meteorological disaster warning may also include alerts and preventative measures.

[0061] This embodiment reduces the amount of data processing by dividing different regions into grids with different precision, while also enabling the delivery of different meteorological disaster warnings to different regions, thus improving the accuracy of meteorological disaster warnings.

[0062] In one embodiment, the meteorological disaster early warning method for a specific area provided in this application may further include:

[0063] Step 610: Divide the region to be processed based on the second precision region grid to obtain the target region;

[0064] Step 620: Determine the receiving subject corresponding to the target segmentation region;

[0065] Step 630: Based on the target area division, continuously update the meteorological disaster information to obtain disaster update information;

[0066] Step 640: Send a meteorological disaster warning containing the disaster update information to the receiving entity.

[0067] Specifically, as described above, after dividing the sparse region into grids based on the second precision, a second-precision region grid is obtained. This second-precision region grid is then used to divide the area to be processed, resulting in multiple smaller subdivided regions, which are the target subdivided regions in this embodiment (the shape of the subdivided regions is not limited; they can be regular shapes or naturally formed shapes, such as naturally formed mountains and lakes). Further, the receiving entity corresponding to each target subdivided region is determined. This correspondence may or may not be within the target subdivided region. For example, if a communication signal transmitting device exists within the target subdivided region, other receiving devices within other target subdivided regions are also the receiving entities corresponding to that target subdivided region.

[0068] For sparse regions, the predicted meteorological disaster information needs to be more accurate. Therefore, after obtaining the target region, the meteorological disaster information is continuously updated based on the target region. The purpose of the update is to obtain the meteorological disaster information corresponding to the target region, so as to make the meteorological disaster information more accurate. After obtaining the updated disaster information, the meteorological disaster warning containing the updated disaster information is sent to the receiving subject.

[0069] This embodiment updates the disaster information of the target area obtained by dividing the area into second-precision area grids, making the meteorological disaster information of sparse areas more accurate.

[0070] Figure 2 This is the second flowchart of the meteorological disaster early warning method for specific areas provided by the present invention, as shown below. Figure 2 As shown, the method may further include:

[0071] Step 310: If the area type is a dense area, obtain the communication cell coverage area within the area to be processed;

[0072] Step 320: Based on the locational relationship between the communication cell coverage area and the disaster-bearing entity, and the communication density corresponding to the communication cell coverage area, determine the area grid division accuracy of the area to be processed; the communication density is determined based on the number of communication receiving devices within the communication cell coverage area;

[0073] Step 330: Divide the region to be processed into a grid based on the grid division accuracy to obtain a first-precision region grid within the region to be processed.

[0074] Specifically, in densely populated areas, further regional division is needed. This division can be based on the coverage area of ​​communication cells, as each communication base station has its corresponding coverage area. There is a locational relationship between the coverage area and the disaster-bearing entity; the number of communication receiving devices within each coverage area determines the corresponding communication density. To send timely and accurate meteorological disaster warnings, the precision of the regional grid division for the area to be processed is determined based on the locational relationship between the coverage area and the disaster-bearing entity, as well as the corresponding communication density. Higher communication density results in higher regional grid division precision. A first-precision regional grid is then determined within the area to be processed based on the locational relationship between the coverage area and the disaster-bearing entity, and the corresponding communication density.

[0075] This embodiment accurately determines the first-precision area grid within the area to be processed by using the locational relationship between the communication cell coverage area and the disaster-bearing entity, as well as the communication density corresponding to the communication cell coverage area.

[0076] In one embodiment, the meteorological disaster early warning method for a specific area provided in this application may further include:

[0077] Step 410: Determine the communication equipment corresponding to the coverage area of ​​the communication cell;

[0078] Step 420: Determine the main location information of the bearer corresponding to the coverage area of ​​the communication cell;

[0079] Step 430: Send the meteorological disaster information corresponding to the coverage area of ​​the communication cell and the main location information to the communication device.

[0080] Specifically, after determining the coverage area of ​​a communication cell, the information of the communication equipment corresponding to each coverage area, as well as the location information of the disaster-bearing entity corresponding to each coverage area, are further determined. The disaster-bearing entity corresponding to each coverage area can be the nearest disaster-bearing entity within the coverage area or a disaster-bearing entity within the entire area to be processed. The meteorological disaster information is further subdivided, distinguishing meteorological disaster information by communication cell coverage area. The meteorological disaster information corresponding to each coverage area, along with the location information of the entity corresponding to each coverage area, is sent to the corresponding communication equipment within each coverage area.

[0081] This embodiment uses the coverage area of ​​the communication cell as a fine granularity to accurately send meteorological disaster information and the location information of the main body to the corresponding communication equipment.

[0082] In one embodiment, the meteorological disaster early warning method for a specific area provided in this application may further include:

[0083] Step 700: Determine the target area grid among multiple first-precision area grids; the meteorological disaster information corresponding to the target area grid contains different meteorological disaster data;

[0084] Step 800: Adjust the grid division precision of the target region grid to obtain a target precision region grid; the grid division precision of the target precision region grid is greater than that of the first precision region grid.

[0085] The step of sending a meteorological disaster warning containing the disaster-bearing entity and the meteorological disaster information to the receiving device corresponding to the first precision area grid includes:

[0086] Step 440: Send a meteorological disaster warning containing the disaster-bearing entity and the meteorological disaster information to the receiving device corresponding to the first precision area grid and the receiving device corresponding to the target precision area grid.

[0087] Specifically, after dividing the data into multiple first-precision raster regions, each first-precision raster region is analyzed to screen for target raster regions. Each target raster region corresponds to at least two types of meteorological disaster data, meaning that the meteorological disaster information corresponding to the target raster region contains different meteorological disaster data. To further refine the meteorological disaster information, the raster division precision of the target raster region is adjusted by increasing its precision, resulting in target-precision raster regions. The precision of the target-precision raster regions is greater than that of the first-precision raster regions.

[0088] After adjusting the grid division precision, meteorological disaster warnings containing information on the disaster-bearing entity and meteorological disasters are sent to the receiving devices corresponding to the first precision area grid and the receiving devices corresponding to the target precision area grid, respectively.

[0089] This embodiment achieves precise delivery of meteorological disaster early warnings by adjusting the precision of the regional grid.

The disaster-bearing entity refers to the location within the area to be addressed that responds to meteorological disasters; The first precision region grid determination module includes: A communication cell coverage area acquisition unit is used to acquire the communication cell coverage area within the area to be processed when the area type is a dense area. The area grid division accuracy determination unit is used to determine the area grid division accuracy of the area to be processed based on the positional relationship between the communication cell coverage area and the disaster-bearing entity, and the communication density corresponding to the communication cell coverage area; the communication density is determined based on the number of communication receiving devices within the communication cell coverage area; A grid division unit is used to divide the region to be processed into a grid based on the region grid division accuracy, so as to obtain a first-accuracy region grid within the region to be processed. The meteorological disaster early warning module includes: A communication device determination unit is used to determine the communication devices corresponding to the coverage area of ​​the communication cell; The main body location information determination unit is used to determine the main body location information of the carrier body that is closest to the first precision area grid within the coverage area of ​​the communication cell; An information transmission unit is used to transmit meteorological disaster information and the main location information corresponding to the coverage area of ​​the communication cell to the communication equipment within the first precision area grid. When the region type is a dense region, after determining the first precision region grid within the region to be processed, the first precision region grid determination module is used for: A target region grid is identified among multiple first-precision region grids; the meteorological disaster information corresponding to the target region grid contains different meteorological disaster data. The grid division precision of the target region grid is adjusted to obtain a target precision region grid; the grid division precision of the target precision region grid is greater than that of the first precision region grid. The step of sending a meteorological disaster warning containing the disaster-bearing entity and the meteorological disaster information to the receiving device corresponding to the first precision area grid includes: A meteorological disaster warning containing information about the disaster-bearing entity and the meteorological disaster is sent to the receiving device corresponding to the first precision area grid and the receiving device corresponding to the target precision area grid.
