The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0030] The following describes the drone cluster system, control method and medium of the embodiment of the present application with reference to the accompanying drawings. In response to the problem of drone cluster control in the absence of electricity and network mentioned in the above background technology, the present application provides a drone cluster system, in which the main drone can autonomously receive satellite communication tasks and efficiently plan routes, which can be completely independent of the ground network or power supply, demonstrating autonomy and flexibility; at the same time, the main drone uses advanced self-organizing network technology to broadcast the planned route to the attached drones in real time, realizing seamless transmission and sharing of information, so that the entire drone cluster can maintain close collaboration in complex or extreme environments without power supply and network communication. Thereby, the problem of the prior art being highly dependent on stable power and network communication, which limits its application efficiency in complex and extreme environments, is solved.

[0031] Specifically, Figure 1 It is a block diagram of the drone cluster system of an embodiment of the present application.

[0032] like Figure 1 As shown, the drone cluster system 10 includes: a main drone 100 and at least one auxiliary drone 200.

[0033] Among them, the main drone 100 receives satellite communication messages, parses the satellite communication messages to obtain target tasks, and plans the target route according to the target tasks; the main drone 100 and at least one auxiliary drone 200 form an ad hoc network, broadcast the target route to at least one auxiliary drone 200 through the ad hoc network, and the main drone 100 and at least one auxiliary drone 200 perform the target task based on the target route.

[0034] It can be understood that in the embodiment of the present application, the main drone 100 autonomously receives satellite missions, plans routes, and shares routes with the auxiliary drones in a self-organizing network, thereby realizing efficient collaborative operation of the drone cluster in an environment without electricity and network, improving mission execution efficiency, coverage and accuracy, and enhancing environmental adaptability and the safety and reliability of mission execution.

[0035] In the embodiments of the present application, Figure 2 As shown, the main UAV 100 includes: a UAV body and a first onboard board arranged on the UAV body; a satellite communication device, a first self-organizing network module and a first control module arranged on the first onboard board, wherein the satellite communication device is used to receive satellite communication messages, the first self-organizing network module is used to self-organize with at least one auxiliary UAV 200, and the first control module is used to parse the satellite communication message to obtain the target task, and broadcast the target route to at least one auxiliary UAV 200 through the self-organizing network.

[0036] It can be understood that in the embodiment of the present application, the main drone 100 realizes autonomous task reception and analysis without ground network support by integrating satellite communication equipment, the first self-organizing network module and the first control module, thereby significantly improving the response speed and flexibility of the drone cluster.

[0037] Specifically, for the master drone 100, when the Beidou receiver receives the Beidou short message, the drone will be started through the first control module, such as Figure 3 As shown, Beidou sends messages to the serial port of the microcontroller via USB (Universal Serial Bus) to TTL (Transistor-Transistor Logic). The microcontroller can be STM32. After receiving the message, the microcontroller distinguishes it and sets the first byte to 0 for a power-on message, 1 for a task message, and 3 for a power-off message. When the microcontroller receives the switch message, it gives a high level to the switch module. The switch module can be EC190708. The high level will turn on the switch module, thereby starting the drone.

[0038] When the drone is started, the airborne module will feedback the message to the user through Beidou to indicate that the drone has been successfully started. When the user receives the feedback, the route is sent to the drone through Beidou. When the microcontroller receives the task message, it will send the message to the airborne board through the serial port and parse it. When the main drone parses and plans the route, it will broadcast it through the self-organizing network module.

[0039] In the embodiments of the present application, Figure 2 As shown, the first onboard board is connected to the power supply of the main drone 100.

[0040] In the embodiments of the present application, Figure 2 As shown, the main drone 100 is also provided with solar photovoltaic panels.

[0041] In the embodiments of the present application, Figure 2 As shown, the first onboard board is also provided with a first power supply for supplying power to the first self-organizing network module and the first control module when the main drone 100 is in a dormant state.

[0042] It can be understood that the first power supply in the embodiment of the present application provides power to the first self-organizing network module and the first control module when the main drone is in sleep mode, ensuring that the drone system can receive emergency communications or instructions from auxiliary drones or other external devices at any time, so that it can respond quickly when needed, significantly improving the overall performance and reliability of the drone system.

[0043] In the embodiments of the present application, Figure 4As shown, the auxiliary drone 200 includes: a drone body and a second onboard board arranged on the drone body; a second self-organizing network module and a second control module arranged on the second onboard board, wherein the second self-organizing network module is used to self-organize with the main drone 100, and the second control module is used to obtain the target route through the self-organizing network, and feedback data to the main drone 100 through the self-organizing network, so as to control the auxiliary drone 200 to perform the target task according to the target route.

[0044] It can be understood that the auxiliary drone 200 in the embodiment of the present application communicates with the main drone 100 through the second self-organizing network module, receives mission instructions and feeds back data in real time, and at the same time the second control module controls it to perform the mission according to the target route, thereby enhancing the collaborative combat capability and mission execution efficiency of the drone cluster.

[0045] Specifically, for the auxiliary drone 200, when the second ad hoc network module receives an MQTT (Message Queuing Telemetry Transport) message, the drone will be started through the second control module, such as Figure 5 As shown, the second self-organizing network module sends a message to the microcontroller serial port through TTL to start the drone. When the drone is started, the onboard board will parse the received MQTT message to generate a route and provide feedback after the parsing is completed.

[0046] In the embodiments of the present application, Figure 4 As shown, the second onboard board is connected to the power supply of the attached UAV 200.

[0047] In the embodiments of the present application, Figure 4 As shown, the auxiliary drone 200 is also provided with solar photovoltaic panels.

[0048] In the embodiments of the present application, Figure 4 As shown, the second onboard board is also provided with a second power supply for supplying power to the second ad hoc network module and the second control module when the attached UAV 200 is in a dormant state.

[0049] It can be understood that in the embodiment of the present application, the second power supply of the auxiliary drone 200 supplies power to the second self-organizing network module and the second control module when in sleep mode, ensuring smooth communication links and improving system flexibility, reliability and low-power standby capability.

[0050] According to the drone cluster system proposed in the embodiment of the present application, the main drone can autonomously receive satellite communication tasks and efficiently plan routes, which can be completely independent of ground networks or power supply, demonstrating autonomy and flexibility; at the same time, the main drone uses advanced self-organizing network technology to broadcast the planned routes to the attached drones in real time, realizing seamless transmission and sharing of information, so that the entire drone cluster can still maintain close collaboration in complex or extreme environments without power supply and network communication. In this way, the existing technology is highly dependent on stable power and network communication, which limits its application efficiency in complex and extreme environments.

[0051] Next, the drone cluster control method proposed in accordance with an embodiment of the present application is described with reference to the accompanying drawings.

[0052] Figure 6 A flowchart of the drone cluster control method provided in an embodiment of the present application.

[0053] like Figure 6 As shown, the drone cluster control method is used to control the drone cluster in the above drone cluster system, wherein the method includes the following steps:

[0054] In step S101, a satellite communication message is sent to a master drone of the drone cluster system via satellite communication, wherein the satellite communication message is parsed to obtain a target task, and the master drone plans a target route according to the target task.

[0055] It can be understood that the embodiment of the present application sends satellite communication messages to the main drone of the drone cluster system through satellite communication. The main drone can understand the target task to be performed by parsing the instructions, so as to quickly respond and plan the route, thereby improving the timeliness of task execution.

[0056] It should be noted that before parsing the satellite communication message, Figure 7 As shown in the figure, the user selects the regional corner points through the Beidou master control end, encodes the regional corner points into a binary code stream, and sends it to the Beidou receiver. The Beidou receiver continuously monitors Beidou messages. When a Beidou message is received, the Beidou receiver feedbacks the receipt of the message. When data packet loss occurs due to special reasons such as communication blocking, the Beidou transmitter will continue to send waypoint information until it receives information feedback from the Beidou receiver.

[0057] In step S102, an ad hoc network is established through communication between the master drone and at least one subordinate drone, and the target route is broadcast to the at least one subordinate drone through the ad hoc network.

[0058] It can be understood that the embodiment of the present application achieves efficient communication and collaborative work through the self-organizing network technology between the main drone and the auxiliary drones, improves the efficiency and accuracy of task execution, and enhances the flexibility and robustness of the system.

[0059] In step S103, the master UAV and at least one subordinate UAV are controlled to perform a target mission based on a target route.

[0060] It can be understood that in the embodiment of the present application, through the pre-planned target route, the main drone and the auxiliary drone can accurately locate their own flight paths, reduce blindness and uncertainty during the flight process, form a collaborative operation mode, jointly complete the target tasks, and improve work efficiency.

[0061] It should be noted that the aforementioned explanation of the drone cluster control system embodiment is also applicable to the drone cluster control method of this embodiment, and will not be repeated here.

[0062] According to the drone cluster control method proposed in the embodiment of the present application, the main drone can autonomously receive satellite communication tasks and efficiently plan routes, which can be completely independent of ground networks or power supply, demonstrating autonomy and flexibility; at the same time, the main drone uses advanced self-organizing network technology to broadcast the planned routes to the attached drones in real time, realizing seamless transmission and sharing of information, so that the entire drone cluster can still maintain close collaboration in complex or extreme environments without power supply and network communication. In this way, the existing technology is highly dependent on stable power and network communication, which limits its application efficiency in complex and extreme environments.

[0063] The following is an explanation of the drone cluster control method through a specific embodiment, as follows:

[0064] like Figure 8 As shown, the Beidou main control end and the receiving end are located in different geographical locations. The Beidou receiving end is mounted on the main UAV and connected to the computing board through the serial port and the single-chip microcomputer. The computing board can read the Beidou receiving end information. Once the Beidou information is received, it will be decoded and processed. The computing board will plan the task according to the decoded information, including: route planning and UAV planning. The planned route will be sent to each subsidiary UAV through the broadcast mechanism.

[0065] like Fig. 9 As shown, after receiving the broadcast route information, the service drone will broadcast feedback. When the main drone confirms that all drones have received the route information, it will send the task execution information, and all drones will switch to sending drone status information.

[0066] It should be noted that after the master drone receives the heading information and plans the route, it broadcasts it, such as Fig.10 As shown in the figure, the main drone will start to collect and respond to the feedback information of the auxiliary drones. When the number of route information sent is equal to the number of feedback information, the main drone will send a route execution command and switch to the broadcast drone state. At this time, the auxiliary drone receives the route execution command and starts to execute the task and switches to the broadcast drone state. If the main drone has not received the corresponding feedback information, it will broadcast again and increase the number of broadcasts by one. When the number of broadcasts is greater than the threshold, it indicates that the auxiliary drone is in an error state. The main drone will re-plan the route and remove the drone number without feedback.

[0067] Due to the character limit of Beidou short message, the Beidou communication format is as follows: {region corner point, region corner point, region corner point, region corner point, number of drones, mission type, whether the transmission is completed}. When the content sent exceeds the Beidou character limit, the end of the short message will indicate that the transmission is not completed, and the Beidou receiver will continue to wait for Beidou messages until the information transmission is completed.

[0068] In summary, the embodiments of the present application realize autonomous control of a long-distance drone cluster in an environment without electricity and network, and through the built-in intelligent system and solar photovoltaic panels, the system's autonomous operation capability and environmental adaptability are comprehensively improved.
