Description

Technical Field

[0001] The present invention relates to the field of emergency broadcasting, and in particular to a monitoring method for emergency broadcasting. Background Art

[0002] Although drone relay communication has many advantages in emergency communications, it also has some disadvantages and challenges. The following is a detailed analysis:

[0003] Limited communication distance and coverage: Drone relay communications primarily rely on line-of-sight (LoS) links, and communication distance is limited by terrain and obstacles. For example, in urban environments, tall buildings may block signal transmission, leading to communication interruptions.

[0004] Resource allocation and optimization are difficult. When multiple drones collaborate to transmit, it is necessary to optimize trajectory planning and resource allocation. It is common for relay node drones to run out of power, resulting in interruption of communication links.

[0005] Therefore, there is an urgent need for a monitoring method for emergency broadcasting to solve the many drawbacks that arise when drones perform emergency broadcast relaying. Summary of the Invention

[0006] The present invention provides a monitoring method for emergency broadcasting, which solves the problems of the prior art.

[0007] In a first aspect, the present invention provides a method for monitoring emergency broadcasting, comprising:

[0008] Multiple drones set out from the monitoring terminal to the emergency broadcast target area to establish drone communication links;

[0009] The monitoring terminal receives the power data of the drones that have reached the corresponding position along the drone communication link in sequence;

[0010] The monitoring terminal analyzes the power data and the corresponding UAV's geographic location, and outputs the power range for each UAV path corresponding to the UAV's communication. The UAV moves to the corresponding position under different power conditions according to the power range.

[0011] The communication links of multiple drones continuously transmit the emergency broadcast data sent by the monitoring terminal throughout the entire cycle.

[0012] Furthermore, the multiple drones set out from the monitoring terminal to the emergency broadcast target area to establish a drone communication link, including:

[0013] Monitor the geographical location of the target area;

[0014] The number of drones in the formation and the flight destination;

[0015] Set the endpoints of adjacent drones to be separated by a communication distance, where the communication distance is the 3dB beam width of the two drones performing data transmission and reception;

[0016] The time period for the numbered drones to switch the transceiver antenna switches is used to form a drone communication link by sequentially and continuously switching the transceiver antenna switches of adjacent drones to transmit data in both directions.

[0017] Furthermore, the number of drones in the formation and their flight destinations; setting a communication distance between the endpoints of adjacent drones, where the communication distance is a 3dB beam width for two drones to transmit and receive data, further specifically includes:

[0018] Two teams of drones are flown in formation to the emergency broadcast target area to form two communication links;

[0019] The distance between the two closest drones in the two teams is half of the communication distance.

[0020] Furthermore, the monitoring terminal sequentially receives power data of the drones that have reached the corresponding location along the drone communication link, including:

[0021] Record the flight power consumption value when the drone reaches the corresponding set position;

[0022] Record the power consumption of the UAV when performing the emergency broadcast communication mission after arriving at the corresponding set location.

[0023] Furthermore, the calculation of the flight power consumption value and the emergency broadcast communication task power consumption value specifically includes:

[0024] The flight power loss of each two adjacent drones in the same formation is calculated based on the flight power loss transmitted back to the monitoring terminal by the drones. The estimated flight power loss of the exchanged positions is calculated based on the power of the adjacent drones in two different formations.

[0025] Furthermore, the monitoring terminal analyzes the power data and the corresponding UAV geographic location, and outputs the power range of each UAV path corresponding to the UAV performing communication. The UAV moves to the corresponding position under different power conditions according to the power range, including:

[0026] The two formations of drones include a first formation of drones and a second formation of drones, and the end position of each drone in the second formation of drones is staggered by half the communication distance from the drones in the corresponding sequence of the first formation of drones;

[0027] The spatial formation formed by two drones in different formations after flying to corresponding positions is a triangle;

[0028] The drones corresponding to the two adjacent triangles that share two vertices are located in the first formation and the second formation respectively;

[0029] In two adjacent triangles, according to the instructions of the monitoring terminal, a group of three drones each time flies clockwise or counterclockwise to the next flight destination, that is, at least one drone flies to the position of the corresponding drone in the other formation each time.

[0030] Furthermore, the monitoring terminal analyzes the power data and the corresponding UAV geographic location, outputs the power range of each UAV path corresponding to the UAV performing communication, and the UAV moves to the corresponding position under different power conditions according to the power range, further comprising:

[0031] Two formations with a total of five adjacent drones as vertices form three triangles;

[0032] And the middle triangle of the three triangles shares a side with each of the two adjacent triangles, and the sides they share are two different sides of the middle triangle;

[0033] Two of the five adjacent drones form the first formation and the other three form the second formation, or two of the five adjacent drones form the second formation and the other three form the first formation;

[0034] The two UAVs that are the farthest apart from the three adjacent UAVs in the same formation move by receiving commands from the monitoring terminal. Specifically:

[0035] When the battery of one of the two UAVs that are the farthest apart is in critical condition, it changes its position in a counterclockwise order through the triangle where it is located and flies to the position of the UAV in the middle position of the original three adjacent UAVs, and then exchanges its position in a counterclockwise order through the other triangle where the UAV with critical condition is located and flies to the original position of the other UAV among the two UAVs that are the farthest apart. Among them, only one of the two triangles with the same vertex in the three triangles is changed each time it moves.

[0036] Furthermore, the monitoring terminal analyzes the power data and the corresponding UAV geographic location, outputs the power range of each UAV path corresponding to the UAV performing communication, and the UAV moves to the corresponding position under different power conditions according to the power range, further comprising:

[0037] The monitoring terminal sets the power range for each drone at the flight end point on the communication link to perform the communication task, and periodically transmits back the drones at different positions whose power does not meet the power range requirements through the position change of the two formation drones. The transmission rule is to transmit in a clockwise or counterclockwise order according to the triangle formed by the drones as the vertices.

[0038] Furthermore, the multiple UAVs continuously transmit the emergency broadcast data sent by the monitoring terminal via the communication link during the entire cycle, including:

[0039] When the drones are not moving, emergency broadcast data and power data are transmitted back in sequence in the corresponding formation through the communication link. The two drone formations correct each other's data and supplement the lost packet data.

[0040] Furthermore, the multiple UAVs continuously transmit the emergency broadcast data sent by the monitoring terminal via the communication link throughout the entire cycle, further comprising:

[0041] During the movement of the drone after receiving the dynamic movement command, three adjacent drones in the same triangle are selected. When each formation transmits emergency broadcast data to the moving drone in the communication link, the next closest drone is selected to transmit the data. When the distance is close, data is transmitted to two different drones respectively.

[0042] The present invention provides a monitoring method for emergency broadcasts, which plans the position movement of drones and forms a self-circulation of drones under effective communication data coverage, thereby reducing the burden on operators, preventing communication link interruptions caused by power outages, and improving the intelligence level of the system.

[0043] The drone formation provided by the present invention can effectively resist external interference through multi-link transmission and communication distance setting, ensuring stable operation in complex electromagnetic environments. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention, as detailed in the appended claims.

[0050] The specific application scenario of this invention is the emergency broadcast communication link built by drones.

[0051] The present invention provides a monitoring method for emergency broadcasting, aiming to solve the above technical problems in the prior art.

[0052] The following describes in detail the technical solution of the present invention and how the technical solution of the present invention solves the above-mentioned technical problems using specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The following embodiments of the present invention are described in conjunction with the accompanying drawings.

[0053] Example 1: UAV formation and communication link establishment: In a natural disaster area, emergency information needs to be quickly broadcast to the affected people. Multiple UAVs start from the monitoring terminal and establish a communication link for emergency broadcasting, forming a Figure 1 The communication link established by the drones in Formation 1 is shown with only three drones, though the number can be expanded as needed. The five drones are divided into two formations: Formation 1, consisting of three drones, and Formation 2, consisting of two drones. Departing from the monitoring terminal to the right, one group forms a triangular formation, while the other group staggers half the communication distance, forming another triangular communication link within the target area. The triangular formation ensures stable communication coverage, while staggered distances reduce signal interference. The number of formations and flight endpoints can also be determined based on the target area's geographic location and communication requirements. The distance between adjacent drone endpoints is set to the communication distance corresponding to a 3dB beamwidth to ensure effective communication coverage. The drones switch their transmit and receive antennas in order of number, and adjacent drones transmit data in both directions, establishing a stable communication link.

[0054] Power Data Monitoring and Analysis: The monitoring terminal receives real-time power data from each drone, recording both flight power consumption and power consumption during communication missions. The monitoring terminal analyzes power data and geographic location to set a power range for each drone's route. When a drone's power level approaches the lower limit of the range, the flight mission or location is adjusted to ensure stable communication.

[0055] Emergency broadcast data transmission: Once the communication link is established, the monitoring terminal continuously transmits emergency broadcast data to the drone. The drone transmits data stably throughout the entire cycle, ensuring that the affected area receives emergency information uninterruptedly.
