[0035] It should be noted that the execution subject of the interactive numerical simulation area setting method provided in the embodiment of the present invention may be one or more electronic devices, which is not limited by the present invention; wherein, the electronic device may be a terminal (i.e., a client) or a server, then when the execution subject includes multiple electronic devices, and the multiple electronic devices include at least one terminal and at least one server, the interactive numerical simulation area setting method provided in the embodiment of the present invention may be jointly executed by the terminal and the server. Accordingly, the terminal mentioned here may include but is not limited to: smart phones, tablet computers, laptops, desktop computers, smart watches, smart voice interaction devices, smart home appliances, vehicle terminals, aircraft, and the like.

[0036] Based on the above description, an embodiment of the present invention proposes an interactive numerical simulation area setting method, which can be executed by the electronic device (terminal or server) mentioned above; or, the interactive numerical simulation area setting method can be executed by the terminal and the server together. For the sake of convenience, the following description will be given by taking the electronic device executing the interactive numerical simulation area setting method as an example; Figure 1 As shown, the interactive numerical simulation area setting method may include the following steps S101-S105:

[0037] S101, obtaining an area setting parameter set, the area setting parameter set including area coordinate data of each layer of nested areas in M ​​layers of nested areas, and one area coordinate data includes initial coordinates of each target vertex among P target vertices included in the corresponding nested area, and M and P are both positive integers.

[0038] Among them, the area setting parameter set can be obtained through the parameter setting operation performed by the target object. Optionally, the target object can be any object, which is not limited by the present invention. Optionally, the area setting parameter set can also include but is not limited to: the spatial resolution of each layer of nested areas in the N layers of nested areas included in the M layers of nested areas (including lateral resolution and longitudinal resolution, such as 9km (kilometer) × 9km, which can also be referred to as resolution), the number of nested layers (that is, the value of M), and the nested area identification, etc.; the present invention is not limited to this. Among them, N is a positive integer less than or equal to M; when N is equal to M, the area setting parameter set may include the resolution of each layer of nested areas in the M layers of nested areas, and the electronic device can determine the resolution of each layer of nested areas from the area setting parameter set. It should be noted that a resolution can be used to indicate the size of the grid spacing, that is, the distance between two adjacent points of the corresponding nested area in the plane rectangular coordinate system.

[0039] Optionally, the nested area identifier may be a nested area name, or a nested area number, etc., which is not limited in the present invention. For example, taking the nested area name as the nested area identifier as an example, the nested area name may be area name 1-area name 2-area name 3, and the nested area identifier may indicate that the first-layer nested area is the area indicated by area name 1, the second-layer nested area is the area indicated by area name 2, the third-layer nested area is the area indicated by area name 3, and so on.

[0040] In one embodiment, the electronic device may display a parameter setting interface; in this case, the target object may perform a parameter setting operation in the parameter setting interface, and the electronic device may respond to the parameter setting operation performed by the target object and use the parameters set by the parameter setting operation as parameters in the regional setting parameter set to obtain the regional setting parameter set, that is, the regional setting parameter set may include the parameters set by the parameter setting operation.

[0041] For example, Figure 2 As shown, assuming that the regional setting parameter set includes the regional coordinate data of each nested region, the resolution of the first nested region, the number of nesting layers, and the nested region identifier, then when the initial coordinates of a point refer to the coordinates of the corresponding point in the geographic coordinate system (i.e., longitude and latitude coordinates), and the P target vertices in a nested region include the lower left corner point and the upper right corner point of the corresponding nested region, the target object can perform parameter setting operations in the parameter setting interface to set the nested region identifier, the number of nesting layers, the longitude and latitude of the lower left corner point in each nested region, the longitude and latitude of the upper right corner point in each nested region, and the resolution of the first nested region. It can be seen that the embodiment of the present invention allows the target object to conveniently set the regional setting parameter set, which can reduce the requirements for the user (i.e., the target object), so that the subsequent numerical simulation regional configuration file can be generated through the setting of the regional setting parameter set to realize the operation of the target numerical model.

[0042] Optionally, the electronic device may display the setting area of ​​each nested area in the parameter setting interface based on the number of nested layers set by the target object, so that the target object can set the regional coordinate data and / or resolution of each nested area in the corresponding setting area; for example, when the number of nested layers is 2 (i.e., two layers), the setting areas of the first layer nested area and the second layer nested area may be displayed, such as Figure 2 Optionally, the number of nesting levels can be input through the target object, or can be selected by the target object in the nesting level setting area, which is not limited in the present invention.

[0043] In another embodiment, the electronic device may support voice input; in this case, the target object may perform parameter setting operations, etc., by voice input. For example, the target object may voice input the nested area identifier, the number of nested layers, the area coordinate data of each nested area, etc., to implement the parameter setting operation.

[0044] Optionally, the electronic device itself may store at least one parameter set, in which case the regional setting parameter set may also be obtained through at least one parameter set, that is, the electronic device may select a parameter set from at least one parameter set and use the selected parameter set as the regional setting parameter set. Alternatively, the regional setting parameter set may also be downloaded through a parameter download link, in which case the electronic device may use the parameter set downloaded based on the parameter download link as the regional setting parameter set, and so on.

[0045] S102, determining target coordinates of each target vertex in each nested region based on the region setting parameter set, where the target coordinates of a target vertex refer to the coordinates of the corresponding target vertex in a plane rectangular coordinate system.

[0046] The coordinates of any point in the plane rectangular coordinate system may refer to the target coordinates of any point. Optionally, the P target vertices in any nested region may include the lower left corner point and the upper right corner point in any nested region, or may include the upper left corner point and the lower right corner point in any nested region, etc.; the present invention is not limited to this.

[0047] Optionally, in the embodiment of the present invention, the number of target vertices in any layer of nested regions may be preferably 2, and the P target vertices in any layer of nested regions may preferably include the lower left corner point and the upper right corner point in any layer of nested regions.

[0048] S103, calculating grid quantity indication data of each nested area based on the target coordinates of each target vertex in each nested area.

[0049] Among them, a grid quantity indication data may include the horizontal grid number and the vertical grid number of the corresponding nested area.

[0050] In one embodiment, the P target vertices in a layer of nested areas include a lower left corner point and an upper right corner point in the corresponding nested areas, and the target coordinates of the lower left corner point in the layer of nested areas are the minimum coordinates of the corresponding nested areas in the plane rectangular coordinate system, and the target coordinates of the upper right corner point in the layer of nested areas are the maximum coordinates of the corresponding nested areas in the plane rectangular coordinate system. In other words, the target coordinates of the upper right corner point in one layer of nested areas are greater than the target coordinates of any point in the corresponding nested areas except the upper right corner point (that is, the horizontal coordinate in the target coordinates of the upper right corner point in one layer of nested areas is greater than or equal to the horizontal coordinate in the target coordinates of any point in the corresponding nested areas except the upper right corner point, and the vertical coordinate in the target coordinates of the upper right corner point in one layer of nested areas is greater than or equal to the vertical coordinate in the target coordinates of any point in the corresponding nested areas except the upper right corner point), and the target coordinates of the lower left corner point in one layer of nested areas are less than the target coordinates of any point in the corresponding nested areas except the lower left corner point (that is, the horizontal coordinate in the target coordinates of the lower left corner point in one layer of nested areas is less than or equal to the horizontal coordinate in the target coordinates of any point in the corresponding nested areas except the lower left corner point, and the vertical coordinate in the target coordinates of the lower left corner point in one layer of nested areas is less than or equal to the vertical coordinate in the target coordinates of any point in the corresponding nested areas except the lower left corner point).

[0051] Based on this, when calculating the grid quantity indication data of each nested area based on the target coordinates of each target vertex in each nested area, for the m-th nested area in the M-th nested area, the electronic device can determine the horizontal resolution and vertical resolution of the m-th nested area, m∈[1,M]; and can determine the first target horizontal coordinate and the first target vertical coordinate in the m-th nested area from the target coordinates of the lower left corner point in the m-th nested area, and determine the second target horizontal coordinate and the second target vertical coordinate in the m-th nested area from the target coordinates of the upper right corner point in the m-th nested area. Then, the horizontal grid number of the m-th nested area can be calculated based on the difference between the second target horizontal coordinate and the first target horizontal coordinate, and the horizontal resolution of the m-th nested area; and the vertical grid number of the m-th nested area can be calculated based on the difference between the second target vertical coordinate and the first target vertical coordinate, and the vertical resolution of the m-th nested area, so as to realize the calculation of the grid quantity indication data of the m-th nested area.

[0052] Optionally, the area setting parameter set may include the lateral resolution and longitudinal resolution of the m-th nested area (that is, it may include the resolution of the m-th nested area), then the electronic device may determine the lateral resolution and longitudinal resolution of the m-th nested area from the area setting parameter set. Alternatively, the area setting parameter set may include the lateral resolution and longitudinal resolution of the h-th nested area, h∈[1,M]; when m is not equal to h, the electronic device may determine the ratio between the resolution of the m-th nested area and the resolution of the h-th nested area, and determine the lateral resolution and longitudinal resolution of the m-th nested area based on the ratio and the resolution of the h-th nested area. Alternatively, the electronic device may store the resolution of each layer of nested areas in Q layers of nested areas, Q being an integer greater than M, then the electronic device may determine the resolution of the m-th nested area from the resolution of each layer of nested areas in the Q layers of nested areas, and so on.

[0053] Specifically, the electronic device can use formula 1.1 to calculate the number of horizontal grids in the m-th nested area:

[0054] Formula 1.1

[0055] Among them, e_we_m refers to the number of lateral grids in the m-th nested area, lcc_xmax_m may refer to the second target horizontal coordinate in the m-th nested area, lcc_xmin_m may refer to the first target horizontal coordinate in the m-th nested area, and dx_m may refer to the lateral resolution of the m-th nested area.

[0056] Correspondingly, the electronic device can use formula 1.2 to calculate the number of vertical grids in the m-th nested area: Formula 1.2

[0057] Among them, e_sn_m refers to the number of longitudinal grids in the m-th nested area, lcc_ymax_m may refer to the second target longitudinal coordinate in the m-th nested area, lcc_ymin_m may refer to the first target longitudinal coordinate in the m-th nested area, and dy_m may refer to the longitudinal resolution of the m-th nested area.

[0058] In another embodiment, the P target vertices in a layer of nested areas include an upper left corner point and a lower right corner point in the corresponding nested area, the horizontal coordinate in the target coordinates of the upper left corner point in the layer of nested areas is less than or equal to the horizontal coordinate in the target coordinates of any point in the corresponding nested area except the upper left corner point, the vertical coordinate in the target coordinates of the upper left corner point in the layer of nested areas is greater than or equal to the vertical coordinate in the target coordinates of any point in the corresponding nested area except the upper left corner point, the horizontal coordinate in the target coordinates of the lower right corner point in the layer of nested areas is greater than or equal to the horizontal coordinate in the target coordinates of any point in the corresponding nested area except the lower right corner point, and the vertical coordinate in the target coordinates of the lower right corner point in the layer of nested areas is less than or equal to the vertical coordinate in the target coordinates of any point in the corresponding nested area except the lower right corner point. In this case, for the m-th nested area in the M-th nested areas, the electronic device can determine the horizontal resolution and the vertical resolution of the m-th nested area; determine the first target horizontal coordinate and the second target vertical coordinate in the m-th nested area from the target coordinates of the upper left corner point in the m-th nested area, and determine the second target horizontal coordinate and the first target vertical coordinate in the m-th nested area from the target coordinates of the lower right corner point in the m-th nested area. Further, the number of horizontal grids of the m-th nested area can be calculated based on the difference between the second target horizontal coordinate and the first target horizontal coordinate, and the horizontal resolution; the number of vertical grids of the m-th nested area can be calculated based on the difference between the second target vertical coordinate and the first target vertical coordinate, and the vertical resolution.

[0059] S104, determining the parent region of each nested region, and determining the index of each nested region under the corresponding parent region based on the target coordinates of the reference vertex in each nested region, wherein a reference vertex is a vertex among the P target vertices included in the corresponding nested region.

[0060] Optionally, the reference vertex in a layer of nested regions may be the lower left corner point in the corresponding nested region, the upper right corner point in the corresponding nested region, or the upper left corner point in the corresponding nested region, etc.; the present invention is not limited to this. Optionally, the embodiment of the present invention may preferably use the lower left corner point in a layer of nested regions as the reference vertex in the corresponding nested region.

[0061] In the embodiment of the present invention, the parent area of ​​the m-th nested area can be the first-layer nested area in the M-layer nested areas, or can be the m-1-th layer nested area in the M-layer nested areas, and so on; the present invention is not limited to this. It should be understood that the parent area of ​​the m-th nested area includes the m-th layer nested area, that is, the m-th layer nested area is located in the parent area of ​​the m-th layer nested area, that is, the parent area of ​​the m-th layer nested area can be: a layer of nested areas in the M-layer nested areas that includes the m-th layer nested area. Optionally, the parent area of ​​the m-th layer nested area can also be itself; for example, the parent area of ​​the first-layer nested area can be the first-layer nested area.

[0062] Optionally, the electronic device may determine the parent area identifier (such as the parent area name or the parent area number, etc.) of the m-th layer nested area, thereby determining the parent area of ​​the m-th layer nested area based on the parent area identifier of the m-th layer nested area, and one area identifier may be used to indicate the corresponding area. Optionally, the parent area identifier of the m-th layer nested area may be determined from an area setting parameter set, that is, the area setting parameter set may include the parent area identifier of each layer of nested area; or, the parent area identifier of the m-th layer nested area may be determined from the storage space of the electronic device itself, that is, the electronic device itself may store the parent area identifiers of each layer of nested areas in the Q-layer nested areas, and the electronic device may determine the parent area identifier of the m-th layer nested area from the parent area identifiers of each layer of nested areas in the Q-layer nested areas, and so on.

[0063] S105, filling the grid quantity indication data of each nested area and the index of each nested area under the corresponding parent area into the numerical simulation area configuration file, so that the numerical simulation area configuration file is used to support the operation of the target numerical model.

[0064] In an embodiment of the present invention, the grid quantity indication data of each nested area and the index of each nested area under the corresponding parent area can be model parameters of the target numerical model, so as to support the operation of the target numerical model. Then correspondingly, the electronic device can fill the grid quantity indication data of each nested area and the index of each nested area under the corresponding parent area into the numerical simulation area configuration file according to the requirements of the model parameters to generate a configuration file for the operation of the target numerical model, that is, the numerical simulation area configuration file filled with the grid quantity indication data of each nested area and the index of each nested area under the corresponding parent area and other model parameters can be the configuration file for the operation of the target numerical model, that is, the filled numerical simulation area configuration file can be the configuration file for the operation of the target numerical model.

[0065] Specifically, the numerical simulation area configuration file can be a template configuration file. After the electronic device obtains the grid quantity indication data of each layer of nested areas and the model parameters such as the index of each layer of nested areas under the corresponding parent area, it can replace the parameter values ​​in the numerical simulation area configuration file with the obtained model parameters to realize the filling of the numerical simulation area configuration file.

[0066] Optionally, the model parameters in the numerical simulation area configuration file may also include the lateral resolution and longitudinal resolution of the m-th nested area; that is, the electronic device may also fill the lateral resolution and longitudinal resolution of the m-th nested area into the numerical simulation area configuration file.

[0067] Exemplarily, it is assumed that the model parameters in the numerical simulation region configuration file include the parent region identifier of each nested region (here, it is assumed to be the parent region number), the ratio between the resolution of each nested region and the resolution of the corresponding parent region, the index of each nested region under the corresponding parent region, and the grid number indication data of each nested region, and it is assumed that the value of M is 3; in this case, the numerical simulation region configuration file can be as follows Figure 3 As shown. Then correspondingly, Figure 3 As shown, after the numerical simulation area configuration file is filled, the second-layer nested area is taken as an example for explanation. The numerical simulation area configuration file can be used to indicate: the parent area number of the second-layer nested area is 1 (that is, the parent area of ​​the second-layer nested area can be the first-layer nested area), the ratio between the resolution of the second-layer nested area and the resolution of the corresponding parent area is 3 (that is, the resolution of the second-layer nested area is 1 / 3 of the resolution of the corresponding parent area), the index of the second-layer nested area under the corresponding parent area is (84, 86) (that is, the horizontal index under the corresponding parent area can be 84, and the vertical index can be 86), the grid number indication data of the second-layer nested area is (571, 502) (that is, the horizontal grid number can be 571, and the vertical grid number can be 502), and so on.

[0068] It should be understood that Figure 3 The numerical simulation area profile is merely represented by way of example and the present invention does not limit this; for example, the numerical simulation area profile may also include the resolution of the mth nested area, such as the lateral resolution and longitudinal resolution of the 1st nested area; for another example, the numerical simulation area profile may also include the number of nested layers, and so on.

[0069] Optionally, the target numerical model may be a WRF model, a NAQPMS model, a CMAQ model, etc., which is not limited in the present invention. Exemplarily, when the target numerical model is a WRF model, the target numerical model may include at least a WPS module (a preprocessing module in the WRF model), and the WPS module may be used to define the numerical simulation area and grid, interpolate the ground static data (such as terrain, soil parameters, etc.) obtained from an external data source to the numerical simulation area, etc., then the numerical simulation area configuration file may be used to support the operation of the WPS module, and so on.

[0070] The embodiment of the present invention can obtain a regional setting parameter set, which includes regional coordinate data of each layer of nested regions in M ​​layers of nested regions, and one regional coordinate data includes the initial coordinates of each target vertex among the P target vertices included in the corresponding nested region; and based on the regional setting parameter set, the target coordinates of each target vertex in each layer of nested regions are determined, and the target coordinates of a target vertex refer to the coordinates of the corresponding target vertex in the plane rectangular coordinate system. Then, the grid quantity indication data of each layer of nested regions can be calculated based on the target coordinates of each target vertex in each layer of nested regions respectively; further, the parent region of each layer of nested regions can be determined, and the index of each layer of nested regions under the corresponding parent region can be determined based on the target coordinates of the reference vertex in each layer of nested regions respectively, and a reference vertex is a vertex among the P target vertices included in the corresponding nested region. Based on this, the grid quantity indication data of each layer of nested regions and the index of each layer of nested regions under the corresponding parent region can be filled into the numerical simulation region configuration file, so that the numerical simulation region configuration file is used to support the operation of the target numerical model. It can be seen that the embodiment of the present invention can conveniently obtain the numerical simulation area configuration file, thereby effectively saving labor costs; and, the area setting parameter set can be obtained through the parameter setting operation performed by the target object, and interactive numerical simulation area setting can be realized. Based on this, the target object can conveniently realize the setting of the numerical simulation area through the area setting parameter set without mastering the relevant professional knowledge, and can conveniently realize the setting of the numerical simulation area configuration file.

[0071] Based on the above description, the embodiment of the present invention further proposes a more specific interactive numerical simulation area setting method. Accordingly, the interactive numerical simulation area setting method can be executed by the electronic device (terminal or server) mentioned above; or, the interactive numerical simulation area setting method can be executed by the terminal and the server together. For the sake of convenience, the following description will be given by taking the electronic device executing the interactive numerical simulation area setting method as an example; see Figure 4 , the interactive numerical simulation area setting method may include the following steps S401-S407:

[0072] S401, obtaining a region setting parameter set, wherein the region setting parameter set includes region coordinate data of each layer of nested regions in M ​​layers of nested regions, and one region coordinate data includes initial coordinates of each target vertex in P target vertices included in the corresponding nested region.

[0073] Optionally, the initial coordinates of a target vertex may refer to the coordinates of the corresponding target vertex in a geographic coordinate system, or may refer to the coordinates of the corresponding target vertex in a plane rectangular coordinate system, which is not limited in the present invention.

[0074] In the embodiment of the present invention, when the initial coordinates of a target vertex refer to the coordinates of the corresponding target vertex in the plane rectangular coordinate system, the electronic device can directly use the initial coordinates of each target vertex in each nested area as the target coordinates of each target vertex in the corresponding nested area. Correspondingly, when the initial coordinates of a target vertex refer to the coordinates of the corresponding target vertex in the geographic coordinate system, the electronic device can execute steps S402-S404 to determine the target coordinates of each target vertex in each nested area, and the initial coordinates can also be called longitude and latitude coordinates.

[0075] S402: Determine a reference nesting region from the M layers of nested regions, where the reference nesting region includes each layer of nested regions.

[0076] It should be understood that the reference nesting area can be the largest nesting area among the M-layer nesting areas, that is, the reference nesting area can cover each layer of nesting areas; wherein any layer of nesting areas can include any layer of nesting areas itself. Exemplarily, assuming that the value of M is 3, and the first layer of nesting areas includes the second layer of nesting areas and the third layer of nesting areas, and the second layer of nesting areas includes the third layer of nesting areas, in this case, the first layer of nesting areas is the largest nesting area among the M-layer nesting areas, and the electronic device can use the first layer of nesting areas as the reference nesting area.

[0077] S403, based on the initial coordinates of each target vertex in the reference nested area, calculate a projection parameter set, the projection parameter set is used to project the initial coordinates of any point in the geographic coordinate system into the plane rectangular coordinate system, and the projection parameter set supports being filled into the numerical simulation area configuration file.

[0078] Optionally, the projection method adopted by the embodiment of the present invention may be a Lambert Conformal Cononic (LCC) projection method, or a Mercator projection method, etc., which is not limited by the present invention. Optionally, the embodiment of the present invention may preferably use a Lambert projection method for projection; for the sake of convenience, the following description will be given by taking the Lambert projection method for projection as an example. In this case, the above-mentioned projection parameter set may include the parameters of the Lambert projection. Optionally, when the Lambert projection method is used for projection, the target coordinates may also be referred to as LCC coordinates.

[0079] Optionally, the projection parameter set may include central longitude, central latitude, first standard latitude, second standard latitude and standard longitude.

[0080] In one embodiment, the P target vertices in a layer of nested regions include the lower left corner point and the upper right corner point in the corresponding nested region; it should be understood that the horizontal coordinate (i.e., longitude) in the initial coordinates of the upper right corner point in the layer of nested regions is greater than the longitude of the lower left corner point in the corresponding nested region, and the vertical coordinate (i.e., latitude) in the initial coordinates of the upper right corner point in the layer of nested regions is greater than the latitude of the lower left corner point in the corresponding nested region. In this case, the electronic device can determine the first initial horizontal coordinate and the first initial vertical coordinate from the initial coordinates of the lower left corner point in the reference nested region, and determine the second initial horizontal coordinate and the second initial vertical coordinate from the initial coordinates of the upper right corner point in the reference nested region. Further, the electronic device can calculate the central longitude and the standard longitude based on the first initial horizontal coordinate and the second initial horizontal coordinate, respectively; and calculate the central latitude, the first standard latitude, and the second standard latitude based on the first initial vertical coordinate and the second initial vertical coordinate, respectively, so as to calculate the projection parameter set based on the initial coordinates of each target vertex in the reference nested region.

[0081] Specifically, the electronic device can use formula 2.1 to calculate the center longitude:

[0082] Formula 2.1

[0083] Wherein, lon0 refers to the center longitude, lonmin may refer to the first initial horizontal coordinate (i.e., the minimum longitude), and lonmax may refer to the second initial horizontal coordinate (i.e., the maximum longitude). In this case, the center longitude may be the middle value between the maximum longitude and the minimum longitude. Optionally, the standard longitude may be the same as the center longitude, that is, the standard longitude may also be the middle value between the maximum longitude and the minimum longitude.

[0084] Accordingly, electronic devices can use formula 2.2 to calculate the center latitude:

[0085] Formula 2.2

[0086] Among them, lat0 refers to the center latitude, latmax can refer to the second initial ordinate (i.e., the maximum latitude), and latmin can refer to the first initial ordinate (i.e., the minimum latitude). In this case, the center latitude can be the middle value of the maximum latitude and the minimum latitude.

[0087] Accordingly, the electronic device can use formula 2.3 to calculate the first standard latitude:

[0088] Formula 2.3

[0089] Among them, lat_1 can represent the first standard latitude. In this case, the first standard latitude can take a value of one third of the minimum latitude to the maximum latitude.

[0090] Accordingly, the electronic device can use formula 2.4 to calculate the second standard latitude:

[0091] Formula 2.4

[0092] Among them, lat_2 can represent the second standard latitude, and in this case, the second standard latitude can take a value of two-thirds from the minimum latitude to the maximum latitude.

[0093] In another embodiment, the P target vertices in a layer of nested areas include the upper left corner point and the lower right corner point in the corresponding nested area, and so on; it should be understood that the longitude of the lower right corner point in a layer of nested areas is greater than the longitude of the upper left corner point in the corresponding nested area, and the latitude of the upper left corner point in a layer of nested areas is greater than the latitude of the lower right corner point in the corresponding nested area. In this case, the electronic device can determine the first initial horizontal coordinate and the second initial vertical coordinate from the initial coordinates of the upper left corner point in the reference nested area, and determine the second initial horizontal coordinate and the first initial vertical coordinate from the initial coordinates of the lower right corner point in the reference nested area; then calculate the central longitude and the standard longitude based on the first initial horizontal coordinate and the second initial horizontal coordinate; and calculate the central latitude, the first standard latitude and the second standard latitude based on the first initial vertical coordinate and the second initial vertical coordinate, so as to calculate the projection parameter set based on the initial coordinates of each target vertex in the reference nested area.

[0094] Optionally, an embodiment of the present invention may preferably include the lower left corner point and the upper right corner point in the corresponding nested area in the P target vertices in a layer of nested areas; for ease of explanation, the following description will be given by taking the example that the P target vertices in a layer of nested areas include the lower left corner point and the upper right corner point in the corresponding nested areas.

[0095] Furthermore, the electronic device may fill the projection parameter set into the numerical simulation area configuration file so that the numerical simulation area configuration file includes each parameter in the projection parameter set, that is, the corresponding template parameters in the numerical simulation area configuration file may be replaced with the projection parameter set actually calculated.

[0096] S404, using a projection parameter set, projecting the initial coordinates of each target vertex in each nested region to obtain the target coordinates of each target vertex in each nested region, where the target coordinates of a target vertex refer to the coordinates of the corresponding target vertex in a plane rectangular coordinate system.

[0097] Optionally, the LCC coordinates corresponding to the center longitude and latitude may be (0, 0), that is, the center longitude and latitude may be projected to obtain the coordinates (0, 0) in the plane rectangular coordinate system. Optionally, the electronic device may project the initial coordinates of any point using the proj4 tool (a map projection tool) and a projection parameter set; or, may project the initial coordinates of any point using the arcgis tool (a geographic information system software) and a projection parameter set, etc.; the present invention is not limited to this.

[0098] For example, Figure 5 As shown, taking the first layer nested area as a 5*5 grid as an example, when the P target vertices in a layer of nested areas include a lower left corner point and an upper right corner point, the electronic device can project the initial coordinates of the lower left corner point in the first layer of nested areas to obtain the target coordinates of the lower left corner point in the first layer of nested areas, that is, the first target horizontal coordinate and the first target vertical coordinate in the first layer of nested areas can be obtained; correspondingly, the initial coordinates of the upper right corner point in the first layer of nested areas can be projected to obtain the target coordinates of the upper right corner point in the first layer of nested areas, that is, the second target horizontal coordinate and the second target vertical coordinate in the first layer of nested areas can be obtained.

[0099] S405 , calculating grid quantity indication data of each nested region based on the target coordinates of each target vertex in each nested region.

[0100] S406, determining the parent region of each nested region, and determining the index of each nested region under the corresponding parent region based on the target coordinates of the reference vertex in each nested region, wherein a reference vertex is a vertex among the P target vertices included in the corresponding nested region.

[0101] In an embodiment of the present invention, for any layer of nested areas in the M layers of nested areas, the electronic device can determine the parent area grid division indication data of any layer of nested areas, one parent area grid division indication data includes the grid division result of the parent area of ​​the corresponding nested area, and one grid division result can be used to indicate each grid in the corresponding area, that is, the grid division result of any area can be used to indicate the number of horizontal grids, the number of vertical grids and the resolution of any area.

[0102] Based on this, the electronic device can determine the reference grid of any nested area under the corresponding parent area from the grid division result of the parent area of ​​any nested area based on the target coordinates of the reference vertex in any nested area.

[0103] In a specific implementation, a parent area grid division indication data may also include grid point coordinates of each grid in the parent area of ​​the corresponding nested area, and a reference vertex is the lower left corner point in the corresponding nested area (i.e., the point with the smallest coordinates in the corresponding nested area). In this case, the electronic device can determine the reference grid point coordinates corresponding to the target coordinates of the reference vertex in any layer of nested areas based on the target coordinates of the reference vertex in any layer of nested areas and the grid point coordinates of each grid in the parent area of ​​any layer of nested areas, the reference grid point coordinates are greater than or equal to the target coordinates of the reference vertex in any layer of nested areas (that is, the horizontal coordinate in the reference grid point coordinates is greater than or equal to the horizontal coordinate in the target coordinates of the reference vertex in any layer of nested areas, and the vertical coordinate in the reference grid point coordinates is greater than or equal to the vertical coordinate in the target coordinates of the reference vertex in any layer of nested areas), and any grid point coordinates in the parent area of ​​any layer of nested areas that are smaller than the reference grid point coordinates are smaller than the target coordinates of the reference vertex in any layer of nested areas, that is, the reference grid point coordinates are the minimum grid point coordinates of all grid point coordinates in the parent area of ​​any layer of nested areas that are greater than or equal to the target coordinates of the corresponding reference vertex; then, the grid corresponding to the reference grid point coordinates (that is, the grid corresponding to the reference grid point coordinates in the parent area of ​​any layer of nested areas) can be used as the reference grid of any layer of nested areas under the corresponding parent area. Optionally, the grid point coordinates of a grid can be the grid center point coordinates of the corresponding grid, or the grid lower left corner point coordinates of the corresponding grid, etc.; the present invention is not limited to this. It should be understood that since it is not allowed to set the grid outside the parent area, the index acquisition of any nested area is generally taken inward, such as the reference grid point coordinates are greater than or equal to the target coordinates of the lower left corner point in any nested area.

[0104] For example, Figure 6As shown, the grid point coordinates of a grid are the grid lower left corner point coordinates of the corresponding grid as an example for explanation; assuming that the black dot is the reference vertex (i.e., the lower left corner point) in any layer of nested areas, in this case, the target coordinates of the white dot are greater than the target coordinates of the reference vertex in any layer of nested areas, and any grid point coordinates in the parent area of ​​any layer of nested areas that are smaller than the target coordinates of the white dot are smaller than the target coordinates of the reference vertex in any layer of nested areas, then the electronic device can determine the target coordinates of the white dot as the reference grid point coordinates corresponding to the target coordinates of the reference vertex in any layer of nested areas.

[0105] In another specific implementation, a parent area grid division indication data may also include the grid point coordinates of each grid in the parent area of ​​the corresponding nested area, and a reference vertex is the upper right corner point in the corresponding nested area (i.e., the point with the largest coordinates in the corresponding nested area), and so on. In this case, the electronic device can determine the reference grid point coordinates corresponding to the target coordinates of the reference vertex in any layer of nested areas based on the target coordinates of the reference vertex in any layer of nested areas and the grid point coordinates of each grid in the parent area of ​​any layer of nested areas, the reference grid point coordinates are less than or equal to the target coordinates of the reference vertex in any layer of nested areas (that is, the horizontal coordinate in the reference grid point coordinates is less than or equal to the horizontal coordinate in the target coordinates of the reference vertex in any layer of nested areas, and the vertical coordinate in the reference grid point coordinates is less than or equal to the vertical coordinate in the target coordinates of the reference vertex in any layer of nested areas), and any grid point coordinate in the parent area of ​​any layer of nested areas that is greater than the reference grid point coordinates is greater than the target coordinates of the reference vertex in any layer of nested areas, that is, the reference grid point coordinates are the maximum grid point coordinates of all grid point coordinates in the parent area of ​​any layer of nested areas that are less than or equal to the target coordinates of the corresponding reference vertex; then, the grid corresponding to the reference grid point coordinates (that is, the grid corresponding to the reference grid point coordinates in the parent area of ​​any layer of nested areas) can be used as the reference grid of any layer of nested areas under the corresponding parent area.

[0106] Optionally, the electronic device may traverse each grid in a parent area of ​​any layer of nested areas until the coordinates of the base grid point or the reference grid point are determined.

[0107] Furthermore, the electronic device may determine the grid index of the reference grid based on the grid division indication data of the parent region of any layer of nested regions, and use the grid index of the reference grid as the index of any layer of nested regions under the corresponding parent region.

[0108] In a specific implementation, the electronic device may determine the grid index of the reference grid based on the grid division result of the parent area of ​​any layer of nested areas. In this case, the electronic device may determine the grid position of the reference grid in the parent area of ​​any layer of nested areas, and use the grid position of the reference grid in the parent area of ​​any layer of nested areas as the grid index of the reference grid. Exemplarily, assuming that the grid position of the reference grid in the parent area of ​​any layer of nested areas is: the second horizontal grid and the second vertical grid, then the grid position of the reference grid in the parent area of ​​any layer of nested areas may be determined to be (2, 2), that is, the grid index of the reference grid may be (2, 2), such as Figure 6 shown.

[0109] In another specific implementation, a parent area grid division indication data may also include grid indexes of each grid in the parent area of ​​the corresponding nested area, so the electronic device may select the grid index of the reference grid from the parent area grid division indication data of any layer of nested area, and so on. Optionally, the grid index of a grid may be determined based on the position between the center points of each grid in the area, or may be determined based on the position between the lower left corner points of each grid in the area, or may be determined based on the position between the grids in the area, and so on; the present invention does not limit this. For example, if the grid index of a grid is determined based on the position between the lower left corner points of each grid in the area, then when the lower left corner point of any grid is the lower left corner point of the i-th horizontal grid and the j-th vertical grid in the corresponding area, it can be determined that the grid index of any grid may be (i, j), i is a positive integer less than the number of horizontal grids in the corresponding area, j is a positive integer less than the number of vertical grids in the corresponding area, and so on.

[0110] Optionally, when the reference vertex in a layer of nested regions is the lower left corner point in the corresponding nested region, the index of any layer of nested regions under the corresponding parent region can be used to indicate: the starting grid of any layer of nested regions in the corresponding parent region.

[0111] S407, filling the grid quantity indication data of each nested area and the index of each nested area under the corresponding parent area into the numerical simulation area configuration file, so that the numerical simulation area configuration file is used to support the operation of the target numerical model.

[0112] In an embodiment of the present invention, for the mth nested area in the M-layer nested area, the electronic device may further determine the image drawing data of the mth nested area, where one image drawing data includes at least: grid quantity indication data of the corresponding nested area and the index of the corresponding nested area under the corresponding parent area, m∈[1,M]; and based on the image drawing data of the mth nested area, draw the mth nested area. Based on this, the electronic device may draw each layer of nested area. For example, Figure 7 As shown, assuming that the value of M is 2, the electronic device can draw the first layer of nested areas (i.e., d01) and the second layer of nested areas (i.e., d02) based on the image drawing data of each layer of nested areas. Optionally, the electronic device can use the basemap extension package (a map drawing library) of python (a computer programming language) to achieve image drawing. It can be seen that the embodiment of the present invention can visualize the data range of the final simulation result, so that the target object can intuitively understand the area range of each layer of nested areas.

[0113] Optionally, an image rendering data may also include but is not limited to: the resolution of each nested area, the target coordinates of the lower left corner point in the reference nested area, and a projection parameter set, etc.; the present invention is not limited to this.

[0114] Optionally, after obtaining the regional setting parameter set, the electronic device may further determine whether the regional setting parameter set meets the calculation condition; if the calculation condition is met, steps S402-S407 are executed; if the calculation condition is not met, the process ends, such as Figure 8 As shown. It should be noted that the calculation condition can be set according to experience or according to actual needs, and the present invention does not limit this; for example, if the P target vertices in a layer of nested areas include the lower left corner point and the upper right corner point in the corresponding nested area, then when it is detected that the initial coordinates of the lower left corner point in any layer of nested areas are less than the initial coordinates of the corresponding upper right corner point, it can be determined that the calculation condition is met; for example, when it is detected that the area setting parameter set includes every parameter required for calculation, it can be determined that the calculation condition is met, such as when the value of M is 3, and only the area coordinate data of any 2 layers of nested areas are input, it can be determined that the calculation condition is not met, and so on.

[0115] The embodiment of the present invention can obtain a regional setting parameter set, which includes regional coordinate data of each nested area in M ​​layers of nested areas, and one regional coordinate data includes the initial coordinates of each target vertex among the P target vertices included in the corresponding nested area; when the initial coordinates of a target vertex refer to the coordinates of the corresponding target vertex in the geographic coordinate system, a reference nested area can be determined from the M layers of nested areas, and the reference nested area includes each layer of nested areas. Further, based on the initial coordinates of each target vertex in the reference nested area, a projection parameter set can be calculated, and the projection parameter set is used to project the initial coordinates of any point in the geographic coordinate system into a plane rectangular coordinate system, and the projection parameter set supports being filled into a numerical simulation area configuration file; and the projection parameter set can be used to project the initial coordinates of each target vertex in each layer of nested areas, respectively, to obtain the target coordinates of each target vertex in each layer of nested areas, and the target coordinates of a target vertex refer to the coordinates of the corresponding target vertex in the plane rectangular coordinate system. Based on this, the grid quantity indication data of each layer of nested regions can be calculated based on the target coordinates of each target vertex in each layer of nested regions; the parent region of each layer of nested regions is determined, and the index of each layer of nested regions under the corresponding parent region is determined based on the target coordinates of the reference vertex in each layer of nested regions, so that the grid quantity indication data of each layer of nested regions and the index of each layer of nested regions under the corresponding parent region can be filled into the numerical simulation region configuration file, so that the numerical simulation region configuration file is used to support the operation of the target numerical model. It can be seen that the embodiment of the present invention can conveniently obtain the numerical simulation region configuration file to reduce the time of model grid configuration, that is, to reduce the time consumption of the target object, and can effectively save labor costs; and the region setting parameter set can be obtained through the parameter setting operation performed by the target object, then the embodiment of the present invention can realize the interactive numerical simulation region setting through the setting of the region setting parameter set, thereby realizing the filling of the numerical simulation region configuration file, so as to realize the model grid configuration through the numerical simulation region configuration file, which can simplify the user's operation and effectively reduce the probability of parameter errors in the model grid configuration process.
