[0041] Please combine the following Figure 3 The method in the embodiment of the present application is described in detail:

[0042] See also Figure 4 , Figure 4 The present invention provides a flowchart of a method for processing air vortex information of a Beidou beacon. Figure 4 As shown, a method for processing air vortex information based on Beidou beacons is applied to a terminal device of an emergency management system, wherein the emergency management system includes a server connected to the terminal device in communication, and a plurality of Beidou beacons connected to the server in communication through the Beidou system; the method includes:

[0043] S401, receiving a disaster avoidance message from the server.

[0044] Among them, the disaster avoidance message includes descriptive information of the risk area for the target air vortex object event, and the risk area is an area determined according to the motion characteristic data and position characteristic data of the target air vortex object. The motion characteristic data and the position characteristic data are determined according to multiple positioning information of multiple Beidou beacons within the range of the target air vortex object. The disaster type of the target air vortex object includes tornado, and the motion characteristic data includes the moving speed of the target air vortex object.

[0045] Specifically, Beidou beacons are placed at preset intervals in potential areas prone to air vortex object events, so that when air vortex object events occur, Beidou beacons are drawn into the air vortex objects, thereby collecting information in a timely manner. For example, positioning information, temperature, humidity and air pressure of tornadoes are collected by Beidou beacons. The air vortex object drawn into the Beidou beacon is set as the target air vortex object, and each Beidou beacon in the multiple Beidou beacons sends the detected positioning information to the server through the Beidou system, so that multiple positioning information is collected by multiple Beidou beacons within the range of action of the target air vortex object, so that the collected information is more credible. After the server obtains multiple positioning information, motion feature data and position feature data are determined according to the multiple positioning information. Specifically, the motion feature data includes the moving speed and rotation speed of the target air vortex object. Then, the risk area of ​​the target air vortex object is determined according to the motion feature data and the position feature data. Since the multiple positioning information is the information collected by multiple Beidou beacons within the range of action of the target air vortex object, the risk area determined based on the multiple positioning information is more accurate, thereby making the description information of the risk area more credible. The disaster avoidance message includes descriptive information of the risk area for the target air vortex object event, providing data support for the subsequent display of the descriptive information of the risk area.

[0046] S402: Parse the disaster risk avoidance message to obtain description information of the risk area.

[0047] The description information includes image information and / or text information. Specifically, after receiving the disaster risk avoidance message sent by the server, the disaster risk avoidance message is parsed to obtain the description information of the risk area.

[0048] S403: Display the description information of the risk area.

[0049] After obtaining the description information of the risk area, the display area of ​​the terminal device displays the description information of the risk area to facilitate the user to view the information.

[0050] S404: When displaying the description information of the risk area, the server generates evacuation instruction image information according to the basic information of the user, the location feature data and the moving speed.

[0051] Among them, when displaying the description information of the risk area, the basic information of the user is collected, and the evacuation instruction image information is generated based on the basic information, location feature data and motion feature data of the user, so as to instruct the user to evacuate and improve safety.

[0052] S405: Receive the evacuation instruction image information sent by the server.

[0053] The evacuation instruction image information is an image for indicating the evacuation route. After generating the evacuation instruction image information, the server sends the evacuation instruction image information to the terminal device to instruct the terminal device to display the image of the evacuation route.

[0054] S406: Display the evacuation instruction image information.

[0055] Among them, the evacuation instruction image information is displayed through the terminal device.

[0056] It can be seen that in this example, the risk area is determined by using multiple positioning information collected by multiple Beidou beacons within the range of the target air vortex object, thereby improving the accuracy of the determined risk area and making the displayed description information of the risk area more credible. The risk area is determined based on multiple real-time positioning information, which makes the displayed description information of the risk area more timely and accurate, and also improves the accuracy of the determined evacuation instruction image information, thereby improving the safety of users during the evacuation process and ensuring the safety of users on the terminal device side.

[0057] In a possible example, the position characteristic data can be obtained as follows: obtain the horizontal movement data of multiple Beidou beacons in multiple positioning information, and if the movement of the target air vortex object is determined based on the movement data; then determine the moving direction information, the vortex radius and the vortex position information of the target air vortex object based on the movement data, and then generate the position characteristic data based on the moving direction information, the vortex radius and the vortex position information.

[0058] In a specific example, the server obtains the horizontal movement data of multiple Beidou beacons in multiple positioning information, and then generates a movement path map according to the movement data through the server. Then the server detects whether there is a target figure in the movement path map whose similarity with the preset figure is higher than the preset similarity. Among them, since the Beidou beacon rotates around the target air vortex object, the target image can be set to a circle. If it is determined that there is a target figure and the number of target figures is greater than the preset number, the first distance value between the center points of any two target figures is calculated to obtain a distance value set composed of the first distance value. If the server detects that there is a target first distance value greater than or equal to the preset distance value in the distance value set, it is determined that the target air vortex object moves. If the server detects that the first distance values ​​in the distance value set are all less than the preset distance value, it is determined that the target air vortex object moves or not. Determine whether the target air vortex object moves through the movement path map to improve the accuracy of the determination result. If it is determined that the target air vortex object moves according to the movement data, the starting point and the end point of the target air vortex object determined in the movement data are determined, so as to determine the moving direction information according to the starting point and the end point, and the moving direction information includes the moving direction of the target air vortex object. The position information of the end point of the target air vortex object is set as the vortex position information, which is convenient for determining the location of the target air vortex object. The position feature data integrates the moving direction information and the vortex position information to provide data support for the subsequent determination of the risk area.

[0059] In a possible example, the position feature data can be obtained in the following manner: different coordinate position information of each Beidou beacon at different time points in multiple positioning information is obtained, and then multiple coordinate position information of each Beidou beacon is obtained. A coordinate system is generated according to the multiple coordinate position information, and then point cloud data is generated based on the coordinate system, a three-dimensional graph is established according to the generated point cloud data, and the moving direction information, vortex radius and vortex position information of the target air vortex object are calculated from the three-dimensional graph, and the position feature data is generated according to the moving direction information, vortex radius and vortex position information.

[0060] In one possible example, see Figure 5 , Figure 5 A display interface of a terminal device provided in an embodiment of the present application. If the description information includes the image information and the text information, the displaying of the description information of the risk area includes: extracting the image information and the text information in the description information of the risk area; generating a first display interface according to the image information; generating a text floating box 502 according to the text information; and when displaying the first display interface, controlling the text floating box 502 to pop up in the first display interface.

[0061] In a specific example, if the description information includes image information and text information, the terminal device first extracts the image information and text information in the description information of the risk area, generates a first display interface based on the image information, and specifically obtains the display screen data of the terminal device display module 201, adjusts the image size in the image information based on the display screen data, so as to generate the first display interface. For example, refer to Figure 5 The first display interface includes a first element, a second element, a third element and a fourth element. The first element is used to represent the geographical map where the target air vortex object in the image information is located, for example Figure 5 The green mixed image in the middle; the second element is used to characterize the target air vortex object within the image information, such as Figure 5 The red circle shown in the figure, where the black circle in the red circle represents the center point of the target air vortex object; the third element is a red line graphic with an arrow, the red line is used to represent the predicted moving route of the target air vortex object, and the direction of the red arrow represents the moving direction of the target air vortex object; the fourth element is used to represent the boundary of the risk area, and the area selected by the fourth element is the risk area, for example Figure 5 The black dotted line box area shown. And the first display interface can also set fixed icons according to needs, so that the user can promptly determine the status of each functional module on the terminal device side, for example Figure 5 The first display interface includes different elements to facilitate users to quickly identify risk areas. The text information generates a text floating box 502, which has a transparent background to avoid blocking the information in the first display interface. For details, please refer to Figure 5 After determining the first display interface and the text floating box 502, the terminal device displays the first display interface and pops up the text floating box 502 in the first display interface. The text floating box 502 reminds the user of the target air vortex object appearance area to assist the user in understanding the content of the first display interface. The text floating box 502 is used to display text information, such as Figure 5 The text floating box 502 shown: the target air vortex object will appear at the x position. It is understandable that the color of each element is not limited here, but in order to facilitate the user to distinguish, the colors of different elements in the same display interface can be different.

[0062] In a possible example, if the description information includes the image information and the text information, displaying the description information of the risk area includes: extracting the image information and the text information in the description information of the risk area; determining a target image display template from a preset image template database based on the image information and the text information; fusing the image information, the text information and the target image display template to generate a second display interface; and displaying the second display interface.

[0063] In a specific example, if the description information includes image information and text information, the image information and text information in the description information are first extracted, and the terminal device determines the target image display template from a preset image template database based on the image information and text information. The image template database includes the correspondence between different image information, text information and different image display templates. For details, please refer to Figure 6 , Figure 6 Another display interface of the terminal device provided in the embodiment of the present application. Figure 6 As shown, the target image display template includes a first display area 601, a second display area 602 and a third display area 603. The first display area 601 is used to display a preset fixed icon, such as Figure 6 The second display area 602 is used to display text information, such as Figure 6 The second display area 602 shown: the target air vortex object will appear at the x position. The third display area 603 is used to display image information. The third display area 603 includes the fifth element, the sixth element, the seventh element and the eighth element. The fifth element is used to represent the geographical map where the target air vortex object in the image information is located; the sixth element is a red circle, which is used to represent the target air vortex object in the image information; the seventh element is a red line graphic with an arrow, and the red line is used to represent the predicted moving route of the target air vortex object, and the direction of the red arrow represents the moving direction of the target air vortex object; the eighth element is a black dotted box, which is used to represent the boundary of the risk area, and the area selected by the eighth element is the risk area. When obtaining the target image display template, the corresponding target image display template is adapted based on the size of the specific content of the image information and the text information. For example, the more text information content, the larger the display area of ​​the second display area 602 of the determined target image display template is, so as to clearly display the text information and facilitate user reference. After determining the target image display template, according to the size of different display areas in the target display template, the fixed icon, image information and text information are respectively merged into the corresponding display area to generate a second display interface. It is understandable that the specific elements of the third display area 603 can be set according to actual needs, and no limitation is made here. The presentation of different elements facilitates the user to quickly determine the risk area.

[0064] It can be seen that in this example, the corresponding target image display template is determined according to the image information and text information in the description information, thereby improving the efficiency of display interface generation, and the generated interface conforms to the reference habits, is convenient for users to consult, and improves the user experience.

[0065] In a possible example, if the size of the display area of ​​the second display area 602 exceeds a preset size, the display time corresponding to the second display area 602 is obtained. After the display time appears in the second display area 602, the second display area 602 is reduced, and the applicability of the text information in the second display area 602 is reduced. The third display area 603 and the image in the third display area 603 are expanded at the same time to facilitate users to check risk areas and improve user experience.

[0066] In a possible example, if the description information includes image information, a third display interface of preset length and width is generated based on the image information, and the preset length and width are equal to the length and width of the display screen of the display module 201 on the terminal device side. The third display interface includes a ninth element, a tenth element, an eleventh element, and a twelfth element. The ninth element is used to represent the geographical map where the target air vortex object in the image information is located; the tenth element is used to represent the target air vortex object in the image information; the eleventh element is a line graphic with an arrow, and the line is used to represent the moving route of the target air vortex object, and the direction of the arrow represents the moving direction of the target air vortex object; the twelfth element is used to represent the boundary of the risk area, and the area selected by the twelfth element is the risk area. Presentation through different elements facilitates users to quickly determine the risk area.

[0067] In a possible example, if the description information includes text information, the terminal device determines whether the number of characters in the text information exceeds a preset number. If it exceeds, the key information in the text information is extracted, such as the specific location information of the target air vortex object and the starting and ending positions of the risk area, and the fourth display interface is generated according to the key information, so that the user can quickly check and obtain the key information, and then avoid risks. Among them, the user can enter the fifth display interface generated by the complete text information through the control 203 or voice input. The fifth display interface is a long interface, which includes multiple display sub-areas, for example, including a first display sub-area and a second display sub-area, the first display sub-area and the second display sub-area are the same size, and the content of the second display sub-area is associated with the content of the first display sub-area. After the first display sub-area displays a preset period of time, it automatically scrolls or jumps to the second display sub-area, so as to facilitate the user to check the complete text information and improve the user experience. It is understandable that other switching methods can also be used between the multiple display sub-areas included in the long interface, such as switching by clicking the control 203, or switching by user voice, that is, collecting user voice, identifying the switching keywords included in the user voice, that is, switching, and improving the user experience.

[0068] In one possible example, see again Figure 5. The motion characteristic data also includes the rotation speed of the target air vortex object, and the position characteristic data includes the vortex position information, vortex radius and moving direction information of the target air vortex object. The risk area is determined according to the following steps: obtaining the moving speed and the rotation speed in the motion characteristic data, and the vortex position information, the vortex radius and the moving direction information in the position characteristic data; obtaining the radius extension value corresponding to the rotation speed from the preset database, and determining the corresponding potential risk radius 501 according to the radius extension value and the vortex radius in the position characteristic data; obtaining the preset duration; determining the risk area according to the potential risk radius 501, the preset duration, the moving speed, the vortex position information and the moving direction information. The moving speed is determined according to the following steps: obtaining the horizontal movement data of the multiple Beidou beacons in the multiple positioning information; if it is determined that the target air vortex object moves according to the movement data, then determining the moving distance of the target air vortex object according to the movement data; obtaining multiple moving durations in the multiple positioning information; determining the moving speed according to the multiple moving durations and the moving distance.

[0069] In a specific example, the risk area is an area determined according to the motion characteristic data and position characteristic data of the target air vortex object, and the risk area includes the current area where the target air vortex object is located and the area where the predicted target air vortex object will appear. The motion characteristic data includes the rotation speed and moving speed of the target air vortex object, and the position characteristic data includes the vortex radius, vortex position information and moving direction information. Specifically, when multiple Beidou beacons are involved in the target air vortex object, they move under the action of the target air vortex object, thereby collecting multiple positioning information. Among them, the greater the wind speed of the target air vortex object, the greater the rotation speed of the target air vortex object, and the stronger the destructive power. Therefore, in order to improve user safety, the corresponding relationship between different rotation speed ranges and different reference radius extension values ​​is pre-set, so as to add the radius extension value on the basis of the vortex radius, thereby improving the rationality of the determined potential risk radius. Among them, the rotation speed is positively correlated with the reference radius extension value. Specifically, after determining the rotation speed of the target air vortex object, the rotation speed range value to which the rotation speed belongs is determined, and the reference radius extension value corresponding to the rotation speed range value belonging to the rotation speed range value is found, and the reference radius extension value is the radius extension value. The radius extension value is added to the vortex radius and the sum is set as the risk radius 501 corresponding to the target air vortex object.

[0070] The server obtains the horizontal movement data of multiple Beidou beacons in multiple positioning information. If the server determines that the target air vortex object moves according to the movement data, the moving distance of the target air vortex object is determined according to the movement data. Specifically, the server generates a moving path diagram according to the movement data, determines that there are multiple target graphics with a similarity higher than the preset similarity in the moving path diagram, calculates the second distance value between the center points of the two target graphics, and if there is a second distance value between the two target graphics greater than the preset distance value, the target air vortex object is determined to move. The third distance value between any two adjacent target graphics in the moving direction of the moving path diagram is obtained in sequence, and the sum of the third distance values ​​between any two adjacent target graphics is counted, and multiple moving durations in the multiple positioning information are obtained, and the average moving duration is determined based on the multiple moving durations. That is, the moving speed is determined by the sum and the average moving duration, wherein the moving speed represents the speed of the overall movement of the target air vortex object.

[0071] Specifically, the position feature data includes the vortex position information and moving direction information of the target air vortex object. Determine the center point of the target air vortex object in the vortex position information, and the moving direction of the target air vortex object in the moving direction information. Obtain a preset duration, which can be determined based on the duration of the air vortex object with the longest duration in the historical period. Determine the moving path based on the center point and the moving direction, and determine the moving section on the moving route based on the preset duration and the moving speed. The risk radius 501 takes each point on the moving section as the center of the circle, thereby determining the risk area. For example Figure 5 As shown, the black circle in the red circle represents the center point of the target air vortex object. The center point is used as the starting point, and the red line with an arrow represents the moving route. The black dotted line selection area is determined with each point in the red line as the center of the circle. The selection area is the risk area.

[0072] It can be seen that, in this example, the risk area is determined based on the motion feature data and the position feature data, thereby improving the accuracy of the determined risk area.

[0073] In a possible example, the preset duration can be predetermined in the following manner: obtaining environmental data of the moving direction in the moving direction information of the target air vortex object, and the wind speed of the target air vortex object in the motion characteristic data; determining the preset duration according to the environmental data and the wind speed. Specifically, the environmental data is parsed, and the number and volume of obstacles in the moving direction of the target air vortex object are determined at the same wind speed. The more obstacles there are and the larger the volume, the shorter the preset duration; conversely, the fewer obstacles there are and the smaller the volume, the longer the preset duration. The more accurately the preset duration is determined, the higher the accuracy of the determined risk area.

[0074] In a possible example, the basic information includes user location information, user moving speed and user travel mode, the location feature data includes vortex position information and moving direction information of the target air vortex object, and the server generates evacuation instruction image information according to the user's basic information, the location feature data and the motion feature data, including: obtaining the vortex position information and the moving direction information in the location feature data; predicting the moving route of the target air vortex object according to the vortex position information and the moving direction information; obtaining the user location information, the user moving speed and the user travel mode in the basic information travel mode; determining the angle between the user and the moving route according to the vortex position information, the user position information and the moving route; if the angle is within a first preset degree range, determining a reference position on the moving route of the target air vortex object that is closest to the user position in the user position information; determining a reference time for the target air vortex object to reach the reference position from the vortex position information based on the moving speed; determining an evacuation direction according to the reference position and the user position information; generating the evacuation guidance image information according to the reference time, the evacuation direction, the user moving speed and the user travel mode.

[0075] In a specific example, the basic information includes user location information, user movement speed, and user travel mode. The location feature data includes the vortex location information and movement direction information of the target air vortex object. The moving route of the target air vortex object is predicted with the center point of the target air vortex object in the vortex location information as the starting point and the moving direction of the target air vortex object in the movement direction information as the route extension direction. Then, the angle between the user and the moving route is determined based on the vortex location information, user location information, and moving route. For example, see Figure 7 , Figure 7 Another display interface of the terminal device provided in the embodiment of the present application. Figure 7As shown, the display interface includes a geographical map for representing the location of the target air vortex object in the image information; includes a red circle for representing the target air vortex object in the image information, wherein the black circle in the red circle represents the center point of the target air vortex object; includes a red line graphic with an arrow for representing the moving route and moving direction of the target air vortex object, wherein the red line is used to represent the moving route of the target air vortex object, and the red arrow direction represents the moving direction of the target air vortex object; includes a black dotted line for representing the boundary of the risk area, and the area selected by the black dotted line is the risk area; includes a blue circle for representing the user position in the user location information; a black dotted line with an arrow for representing the evacuation direction and evacuation route; includes representing the angle 701 between the user and the moving route. And the display interface can also set fixed icons according to needs, so that the user can determine the status of each functional module on the terminal device side in time.

[0076] The angle degree of angle 701 is calculated based on the vortex position information, user position information and moving route, and then the preset degree range to which the angle degree belongs is determined. The preset degree range is set in advance, for example, a first preset degree range and a second preset degree range are set, the first preset degree range is 0 degrees to 90 degrees, and the second preset degree range is 90 degrees to 180 degrees. If the angle degree is within the first preset degree range, the reference position closest to the user position in the user position information on the moving route of the target air vortex object is obtained. Specifically, first determine the vertical route from the user position to the moving route, and the position of the intersection of the vertical route and the moving route is the reference position. For example Figure 7The yellow circle shown is the reference position. The reference time required for the target air vortex object to reach the reference position from the center point corresponding to the vortex position information is determined based on the moving speed. Since the angle degree of the angle 701 is within the first preset degree range, the target air vortex object will gradually approach the user position, wherein the reference position is closest to the user position. To ensure the safety of the user, the reference position pointing to the user position is set as the evacuation direction, so that the user can quickly move away from the reference position and improve the evacuation efficiency. Determine multiple preset intervals within the reference time, and calculate the moving distance that can be moved using the user's moving speed within a single preset interval. The user's travel mode can be walking, cycling or driving. The evacuation path in the evacuation direction is determined according to the user's travel mode, and the evacuation guidance image information is generated according to the evacuation path and the user's moving distance in each preset interval. For example, if the reference time is 10 minutes and the preset interval period is 1 minute, the moving distance within 1 minute using the user's moving speed is calculated. If the user travels by car, an evacuation path that can be driven by the car in the evacuation direction is planned. The corresponding position of the user on the evacuation path every minute within 10 minutes is determined based on the moving distance that can be moved per minute, thereby generating evacuation guidance image information, making the evacuation guidance image information more timely and accurate.

[0077] If the angle is within the second preset degree range, the evacuation direction is determined according to the vortex position information and the user position information. Specifically, the evacuation direction is the direction from the user position in the user position information to the center point of the target air vortex object in the vortex position information. Multiple preset intervals within the reference time are determined, and the moving distance that can be moved using the user's moving speed in a single preset interval is calculated. The evacuation path in the evacuation direction is determined in combination with the user's travel mode, and the evacuation guidance image information is generated according to the evacuation path and the user's moving distance in each preset interval.

[0078] It can be seen that in this example, evacuation instruction image information is generated based on basic information, location feature data and moving speed, so as to provide users with personalized evacuation guidance image information, improve intelligence, ensure user safety and improve user experience.

[0079] In a possible example, after displaying the evacuation instruction image information, the method further includes: collecting the real-time location information of the user at the current time point; sending the real-time location information to the server; calculating, by the server, a fourth distance value between the reference position and the real-time location in the real-time location information; if the fourth distance value is less than half of the radius of the target air vortex object, that is, when the target air vortex object reaches the reference position, the user position is within the range of the target air vortex object, for example, Figure 7As shown, the red dotted circle line represents the boundary of the target air vortex object when the target air vortex object reaches the reference position. If the user's position is within the red dotted circle line, a vibration generation instruction is sent to the terminal device through the server, and the vibration generation instruction is used to instruct the terminal device to vibrate; after receiving the vibration generation instruction, the terminal device vibrates according to the vibration generation instruction to promptly remind the user to evacuate in time.

[0080] Among them, the vortex radius of the target air vortex object can be determined in the following way: obtain the horizontal movement data of multiple Beidou beacons in multiple positioning information, generate a movement path map based on the movement data, determine the radius of each target graphic in the movement path map, obtain a radius set of the target graphic, obtain a radius average based on the radius set, and set the radius average as the vortex radius of the target air vortex object.

[0081] Specifically, the coordinates of three points of each target figure can be collected, namely (x1, y1), (x2, y2), and (x3, y3), and the coordinates of the three points can be substituted into the general equation of the circle: 2 +y 2 +Dx+Ey+F=0.

[0082] The obtained system of equations includes: x1 2 +y1 2 +Dx1+Ey1+F=0;x2 2 +y2 2 +Dx2+Ey2+F=0;x3 2 +y3 2 +Dx3+Ey3+F=0. Solve the equations to get the values ​​of D, E, and F. Substitute the values ​​of D, E, and F into the formula: Where r is the radius of the target shape. Alternatively, obtain the coordinates of the center of the target shape (a, b) and the coordinates of any point on the target shape (x, y), and substitute the coordinates of the center of the circle and the coordinates of any point into the calculation formula: Wherein r is the radius of the target figure. It is understandable that the method for calculating the radius of the target figure can be set according to actual needs and is not limited here.

[0083] In a possible example, before receiving the disaster avoidance message from the server, the method also includes: determining the level of the target air vortex object based on the movement data, the vortex position information, the movement direction information and the movement speed; searching the database for a message sending range corresponding to the level; and sending the disaster avoidance message to a terminal device of the emergency management system within the message sending range through the server.

[0084] In a specific example, when evaluating the level of the target air vortex object, the higher the wind speed, the faster its rotation speed and the wider the range. The level of the target air vortex object is determined based on the mobile data, vortex position information, moving direction information and moving speed collected by the Beidou beacon. The mobile data is the horizontal movement data of multiple Beidou beacons in multiple positioning information, and the mobile data includes the range of the target air vortex object when it rotates. Specifically, a moving path diagram is generated according to the mobile data, and multiple target graphics with a similarity higher than the preset similarity with the preset graphics in the moving path diagram are determined. The target graphic with the largest area among the multiple target graphics is determined, and the area corresponding to the target graphic with the largest area is determined as the target area. The level of the target air vortex object is determined based on the target area, vortex position information, moving direction information and moving speed. Among them, the greater the moving speed, the higher the level; the larger the target area, the higher the level; the fewer obstacles are determined according to the vortex position information and the moving direction and the closer to the crowd gathering place, the higher the level. For example, when the moving speed is the same as the target area, the target air vortex object is determined to be in the countryside and moving towards the countryside according to the vortex position information and the moving direction. After the level is determined, the higher the level, the larger the range of the corresponding message sending area. After the corresponding message sending area is determined, the information of the terminal device in the message sending area is obtained, and then the disaster avoidance message is sent to the terminal device in the message sending range of the emergency management system through the server. Specifically, the message sending area includes the risk area.

[0085] It can be seen that in this example, the level of the target air vortex object is determined based on the movement data, vortex position information, movement direction information and movement speed, and the rationality and accuracy of the determined level of the target air vortex object are improved. This makes the message sending area determined based on the level more reasonable and accurate, and the disaster avoidance message is sent accurately to save resources.

[0086] In one possible example, the level of the target air vortex object can also be determined based on the wind speed of the target air vortex object in the motion characteristic data. For example, if the wind speed is less than 73 miles per hour, the level is determined to be EF0; if the wind speed is in the range of 73-112 miles per hour, the level is determined to be EF1; if the wind speed is in the range of 113-157 miles per hour, the level is determined to be EF2. It can be understood that the range value of the wind speed corresponding to each level can be set according to actual needs, and there is no limitation here.

[0087] Among them, the wind speed in each sub-period within the preset period can be directly collected, and then based on

[0088] Where v is the final wind speed, v1 is the wind speed corresponding to the first sub-period, v2 is the wind speed corresponding to the second sub-period, and so on.n Is the wind speed corresponding to the nth sub-period. n is the number of corresponding sub-periods. The acceleration of each sub-period in the preset time period is directly collected by the accelerometer in the new Beidou standard, and then brought into the calculation formula v=v0+at, where v is the final wind speed of the sub-period, v0 is the initial wind speed, a is the acceleration, and t is the movement time. If the initial wind speed and acceleration of the Beidou beacon in the target air vortex object are known in each sub-period, the final wind speed can be calculated first, and then the wind speed corresponding to each sub-period is calculated based on the initial wind speed and the final wind speed. It can be understood that the wind speed of the target air vortex object can also be calculated based on the data collected by the Beidou beacon in the target air vortex object and other calculation methods according to actual needs, and the specifics are not limited here.

[0089] It can be seen that in this example, the level of the target air vortex object is determined based on the wind speed collected by multiple Beidou beacons, thereby improving the determination efficiency.
