[0019] If it is determined that the first coordinate position is within the adjustment area, determining a second target coordinate point closest to the corresponding non-mobile communication network area outline according to the first coordinate position;

[0020] Determine a second target line segment of a corresponding non-mobile communication network area according to a line connecting the first coordinate position and the second target coordinate point, and a second preset sector angle range;

[0021] The second target line segment is intercepted and moved to the first coordinate position, and both ends of the second target line segment are respectively connected to the corresponding truncation points of the non-mobile communication network area to obtain a second target area;

[0033] Obtaining the broadcast transmission range of the weather warning watch, and determining whether the broadcast transmission range of the weather warning watch with the second number fully covers the non-mobile communication network area corresponding to the first number;

[0034] If it is determined that the broadcast transmission range of the weather warning watch with the second number fully covers the non-mobile communication network area corresponding to the first number, then when disaster warning information appears, the weather warning watch with the second number is controlled to broadcast;

[0035] If it is determined that the broadcast transmission range of the weather warning watch with the second number does not fully cover the non-mobile communication network area corresponding to the first number, the moving range of the weather warning watch with the first number is deduced, and it is determined whether the broadcast transmission range of the weather warning watch with the second number fully covers the moving range;

[0036] If it is determined that the broadcast transmission range of the second-numbered weather warning watch fully covers the moving range, then when disaster warning information appears, the second-numbered weather warning watch is controlled to broadcast;

[0054] Embodiment 1

[0055] According to an embodiment of the present invention, there is provided an embodiment of a weather warning method based on the real-time position of a weather warning watch. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from that shown here.

[0056] In the first embodiment of the present invention, a weather warning method based on the real-time position of a weather warning watch is provided, which can be used in electronic devices, such as computers. It should be noted that the method is applied to scenarios where the weather warning watch has a heartbeat collection function, as well as a broadcast sending and receiving function.

[0057] See also Figure 1 , Figure 1 A flow chart of an implementation of a weather warning method based on the real-time position of a weather warning watch provided in the first embodiment of the present invention is shown, which specifically includes steps S01 to S05.

[0058] Step S01, connect each weather warning watch to the same server for communication, and obtain the coordinate position of each weather warning watch in real time.

[0059] Among them, the server is a central server. After the central server communicates with each weather warning watch, it can obtain the coordinate position of each weather warning watch. The coordinate position can be the longitude and latitude position, or the position in a pre-established rectangular coordinate system. It can be understood that there is a corresponding relationship between the position in the rectangular coordinate system and the actual longitude and latitude position.

[0060] Step S02, obtaining a mobile communication network area, and marking and displaying corresponding coordinate points in the mobile communication network area based on the coordinate positions of each weather warning watch obtained in real time.

[0061] Specifically, the mobile communication network area refers to the area covered by 4G, 5G and other mobile communication networks. In this area, data can be obtained through 4G, 5G and other mobile communication networks, including meteorological data and geographic location data. Since the geographic location data can be obtained, the corresponding coordinate points can be marked and displayed in the mobile communication network area.

[0062] In addition, mobile communication network areas and non-mobile communication network areas can be planned in advance based on conditions and parameters that affect mobile communication network coverage, such as terrain. Non-mobile communication network areas refer to areas that are not covered by the mobile communication network, that is, areas where Internet access is not available.

[0063] Step S03, controlling each weather warning watch to send the heartbeat data packet to the server in real time.

[0064] Since the weather warning watch has the heartbeat collection function, it can control each weather warning watch to send heartbeat data packets to the server in real time. It can be understood that in areas with mobile communication networks, weather warning watches can send heartbeat data packets and be accepted by the server, while in areas where the network is interrupted, the server cannot receive heartbeat data packets.

[0065] Step S04, obtaining the first coordinate position and first number of the weather warning watch corresponding to the current moment when the server does not receive the heartbeat data packet, and determining the second coordinate position and second number of the weather warning watch closest to the first coordinate position.

[0066] It should be noted that the first coordinate position of the weather warning watch corresponding to the current moment when the server does not receive the heartbeat data packet is obtained, and it is determined whether the first coordinate position is in a non-mobile communication network area outside the mobile communication network area;

[0067] If it is determined that the first coordinate position is in a non-mobile communication network area outside the mobile communication network area, determining a first target coordinate point closest to the corresponding non-mobile communication network area outline according to the first coordinate position;

[0068] Determine a first target line segment of a corresponding non-mobile communication network area according to a line connecting the first coordinate position and the first target coordinate point, and a first preset sector angle range;

[0069] Cutting the first target line segment from the corresponding non-mobile communication network area outline, and moving it along the connecting line toward the first coordinate position until reaching the first coordinate position;

[0070] The curvatures of both ends of the first target line segment are respectively obtained, and according to the curvature, the two ends of the first target line segment are extended until they intersect with the corresponding non-mobile communication network area contour to obtain the first target area. Specifically, the step of respectively obtaining the curvatures of both ends of the first target line segment includes:

[0071] According to the line connecting the first coordinate position and the first target coordinate point, the first target line segment is divided into two segments, and the lengths of the two line segments are respectively obtained;

[0072] According to the preset unit length and the lengths of the two line segments, the two line segments are divided into a number of sub-line segments;

[0073] The curvature of each sub-segment in the two line segments is calculated respectively, and the curvatures at both ends of the first target line segment are determined according to the curvature distribution of each sub-segment in the two line segments. It should be noted that the curvature is divided into different gears in advance, and different gears correspond to a specific curvature. By understanding the curvature distribution of each sub-segment, that is, counting the gear in which the curvature of each sub-segment falls the most, the curvature of the corresponding gear is determined as the curvature for subsequent extension. For example, if the first target line segment is divided into left and right segments, the endpoint of the left line segment is extended using the curvature determined corresponding to the left line segment, and the endpoint of the right line segment is extended using the curvature determined corresponding to the right line segment;

[0074] updating the mobile communication network area according to the first target area;

[0075] If it is determined that the first coordinate position is not in the non-mobile communication network area outside the mobile communication network area, then determining whether the first coordinate position is in the adjustment area, wherein the adjustment area is an area between the initial non-mobile communication network area and the finally updated non-mobile communication network area;

[0076] If it is determined that the first coordinate position is within the adjustment area, determining a second target coordinate point closest to the corresponding non-mobile communication network area outline according to the first coordinate position;

[0077] Determine a second target line segment of the corresponding non-mobile communication network area according to a line connecting the first coordinate position and the second target coordinate point, and a second preset fan-shaped angle range, wherein the first preset fan-shaped angle range is greater than the second preset fan-shaped angle range;

[0078] The second target line segment is intercepted and moved to the first coordinate position, and both ends of the second target line segment are respectively connected to the corresponding cut-off points of the non-mobile communication network area to obtain the second target area;

[0079] If it is determined that the first coordinate position is not within the adjustment area, determining a third target coordinate point closest to the corresponding non-mobile communication network area outline according to the first coordinate position;

[0080] Pull the third target coordinate point to the first coordinate position to obtain a third target area. Specifically, determine two tangent lines between the first coordinate position and the corresponding non-mobile communication network area contour, and determine the tangent point, which is the outermost tangent point;

[0081] Determine the target contour on the corresponding non-mobile communication network area contour according to the tangent point;

[0082] The third target coordinate point is pulled to the first coordinate position. During the pulling process, the target contour changes accordingly to obtain the third target area. Specifically, the corresponding mapping relationship is determined according to the distance between the first coordinate position and the third target coordinate point. According to the mapping relationship, the other coordinate points on the target contour are converted, and the final connection result is the third target area.

[0083] The purpose of the above steps is to continuously update the mobile communication network area as the user with the weather warning watch moves around during work tasks, so that the mobile communication network area becomes more and more accurate, and the broadcast timing of the weather warning watch becomes more and more precise.

[0084] In some other embodiments of the present invention, the broadcast transmission range of the weather warning watch is obtained, and it is determined whether the broadcast transmission range of the weather warning watch with the second number fully covers the non-mobile communication network area corresponding to the first number;

[0085] If it is determined that the broadcast transmission range of the second numbered weather warning watch fully covers the non-mobile communication network area corresponding to the first numbered one, then when disaster warning information appears, the second numbered weather warning watch is controlled to broadcast;

[0086] If it is determined that the broadcast transmission range of the second-numbered weather warning watch does not fully cover the non-mobile communication network area corresponding to the first-numbered weather warning watch, the moving range of the first-numbered weather warning watch is deduced. In order to deduce the moving range, the user's historical moving speed is first analyzed. The analysis data comes from the data collected when there is a mobile communication network. Specifically, the user's moving speed on different roads is calculated, and the possible forward roads of the user in the non-mobile communication network area are obtained. According to the moving speed and the possible forward roads of the user, several routes are drawn, and the ends of the several routes are connected to form a moving range, and it is determined whether the broadcast transmission range of the second-numbered weather warning watch fully covers the moving range;

[0087] If it is determined that the broadcast transmission range of the second numbered weather warning watch will fully cover the mobile range, then when disaster warning information appears, the second numbered weather warning watch is controlled to broadcast;

[0088] If it is determined that the broadcast transmission range of the second-numbered weather warning watch does not fully cover the moving range, the second-numbered weather warning watch is controlled to broadcast the current weather information. It can be understood that when the second-numbered weather warning watch does not cover the moving range, the second-numbered weather warning watch is controlled to broadcast the current weather information.

[0089] Step S05, controlling the second-numbered weather warning watch to broadcast disaster warning information to the first-numbered weather warning watch.

[0090] Specifically, disaster warning information is preferentially broadcast through the second-numbered weather warning watch that is closest to the first-numbered weather warning watch. If the second-numbered weather warning watch has completely left its broadcast range, disaster warning information will be broadcast by other covered weather warning watches.

[0091] In summary, the weather warning method based on the real-time position of the weather warning watch in the above-mentioned embodiment of the present invention connects each weather warning watch to the same server, and obtains the coordinate position of each weather warning watch in real time; obtains the mobile communication network area, and marks and displays the corresponding coordinate point in the mobile communication network area according to the real-time coordinate position of each weather warning watch; controls each weather warning watch to send a heartbeat data packet to the server in real time; obtains the first coordinate position and the first number of the weather warning watch corresponding to the current moment when the server does not receive the heartbeat data packet, and determines the second coordinate position and the second number of the weather warning watch closest to the first coordinate position; controls the second-numbered weather warning watch to broadcast disaster warning information to the first-numbered weather warning watch, so that when the weather warning watch using the mobile communication network is disconnected, it can still receive the disaster warning information received and broadcast by other weather warning watches.
