Abstract
Description
Technical Field
[0001] This application relates to the field of unmanned aerial vehicle (UAV) control technology, specifically to an intelligent management system for UAV mission delegation. Background Technology
[0002] Currently, most drone mission assignments rely on ground base stations for communication and mission distribution. All drone mission reception, status reporting, and scheduling control depend on stable communication links with these ground base stations. However, in real-world scenarios such as low-altitude inspections, field exploration, security operations, and emergency rescue, factors such as obstructions in the wild, complex electromagnetic interference, and signal blind spots in remote areas can easily cause communication link interruptions between drones and ground base stations, resulting in drone communication failures.
[0003] When a drone loses communication, traditional management methods cannot intervene in secondary missions. The drone can only maintain its current state or hover in place, and the remaining unfinished missions are forced to be interrupted, which greatly reduces the integrity and efficiency of drone operations. At the same time, existing methods for handling lost drones mostly rely on manual background checks and manual dispatch of drones to search, which results in delayed response, high labor costs, and the inability to achieve automated and real-time mission continuation. Summary of the Invention
[0004] In view of the deficiencies in the existing technology, the technical problem to be solved by this application is: how to achieve efficient task continuation of UAV when communication is lost.
[0005] To achieve the above objectives, embodiments of this application provide an intelligent management system for unmanned aerial vehicle (UAV) mission delegation, the system comprising:
[0006] The communication monitoring module is used to allow the ground base station to collect and receive status data from each UAV in real time.
[0007] The module for determining the loss of contact is used to mark the drone as a lost drone when it is determined to be lost based on status data, and to determine the last valid location coordinates, remaining unexecuted tasks, task priority and unique encrypted ID of the lost drone.
[0008] The intelligent assignment filtering module is used to match the search drone according to the last valid location coordinates of the missing drone by a preset search filtering rule, and retrieve the exclusive key ID to encrypt and package the remaining unexecuted tasks of the drone. After obtaining the encrypted task data package, the module sends the encrypted task data package and task relay assignment instruction to the search drone.
[0009] A temporary network communication module is used to receive encrypted task data packets and task relay delegation instructions. The search drone establishes a temporary communication base station that is only open to the missing drone through airborne ad hoc network communication. When the missing drone accesses the temporary communication base station, it dispatches encrypted task data packets.
[0010] In one embodiment, the status data includes online status, location data, battery power data, and task execution status.
[0011] In one embodiment, the logic for determining that the drone has lost contact based on status data includes:
[0012] The ground base station monitors the online status of each drone according to a preset heartbeat cycle. If any drone does not transmit data back for a preset number of consecutive heartbeat cycles and does not send an active offline command, the drone is determined to be a lost drone.
[0013] In one embodiment, the process of establishing the preset search and filtering rules includes:
[0014] The search area was determined based on the last valid location coordinates of the missing drone.
[0015] Within the search area, select drones that are currently without a task or performing a task with a lower priority than the missing drone, and whose remaining battery power is greater than a preset threshold, as candidate drones.
[0016] Select the candidate drone that is closest to the center of the search area from all candidate drones and use it as the search drone.
[0017] In one embodiment, the method of determining the search area based on the last valid positioning coordinates of the missing drone is as follows: taking the last valid positioning coordinates of the missing drone as the center of a sphere, and taking a spherical area within a preset radius as the search area.
[0018] In one embodiment, the method by which the search drone establishes a temporary communication base station accessible only to the missing drone via an onboard ad hoc network includes:
[0019] After retrieving the device's dedicated communication channel, device ID, and communication verification key from the ground base station, the communication parameters are bound.
[0020] Based on the bound communication parameters, a temporary communication base station is set up to actively broadcast directional networking signals to the outside world, and access is only granted to lost drones.
[0021] In one embodiment, a timeout reset control module is also included. The timeout reset control module is used to set the reset logic of the search drone. When the search drone meets the reset logic, it is reset to the original flight path and communication with the ground base station is restored.
[0022] In one embodiment, the reset logic includes:
[0023] Record search routes and search duration;
[0024] When the search duration reaches a preset threshold, or when the search duration does not reach the preset threshold and the missing drone establishes communication with the search drone, a return-to-home command is triggered.
[0025] Control the search drone to return along the original search route.
[0026] Compared with the prior art, the advantages of this application are:
[0027] After a drone loses communication, it automatically matches and searches for nearby drones to set up temporary airborne communication base stations and builds a local dedicated communication link. This allows for the reassignment of tasks to lost drones without human intervention, effectively solving the problem of task interruption caused by signal interference and signal blind spots, thereby improving the continuity and integrity of drone field operations.

For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0030] Figure 2 This is a flowchart illustrating the usage method of the UAV mission delegation intelligent management system in an embodiment of the present invention. Detailed Implementation
[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0032] The flowchart shown in the attached diagram is for illustrative purposes only and does not necessarily include all content and operations / steps, nor does it necessarily have to be performed in the order described. For example, some operations / steps can be broken down, combined, or partially merged, so the actual execution order may change depending on the actual situation.
[0033] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0034] This application provides an intelligent management system for unmanned aerial vehicle (UAV) mission assignment, referring to... Figure 1 The system includes a communication monitoring module, a disconnection determination module, an intelligent dispatch screening module, a temporary network communication module, and a timeout reset control module. The communication monitoring module is connected to the disconnection determination module, the disconnection determination module is connected to the intelligent dispatch screening module, and the intelligent dispatch screening module is connected to the temporary network communication module and the timeout reset control module, respectively.
[0035] The communication monitoring module is used to collect and receive status data of each UAV in real time from the ground base station. The status data includes online status, positioning data, power data and task execution status. The disconnection determination module is used to mark the UAV as a disconnected UAV when it is determined to be disconnected based on the status data, and to determine the last valid positioning coordinates, remaining unexecuted tasks, task priority and unique encrypted ID (pre-configured) of the disconnected UAV.
[0036] The intelligent dispatch and screening module is used to match search drones based on the last valid location coordinates of the missing drone using preset search and screening rules. It then retrieves a unique key ID to encrypt and package the remaining unexecuted tasks of the missing drone, obtaining an encrypted task data packet (which can only be decrypted, parsed, and executed locally by the missing drone). Finally, it sends the encrypted task data packet and task relay dispatch instructions to the search drone. This ensures that only the missing drone possesses the corresponding decryption private key for the encrypted task data, while the search drone only performs data forwarding functions and cannot read or tamper with the task content. This prevents task data leakage, accidental access by other devices, and erroneous task execution, effectively improving the data security and uniqueness of drone task dispatch.
[0037] The temporary network communication module (configured on the airborne terminal of each UAV and activated when the UAV is identified as a search UAV) is used to receive encrypted mission data packets and mission relay delegation instructions. The search UAV establishes a temporary communication base station that is only open to the missing UAV through the airborne self-organizing network communication. When the missing UAV accesses the temporary communication base station, it dispatches encrypted mission data packets.
[0038] The timeout reset control module is used to set the reset logic for the search drone. When the search drone meets the reset logic, it is reset to the original flight path and communication with the ground base station is restored.
[0039] This approach automatically matches and searches for nearby drones to set up temporary airborne communication base stations after a drone loses communication, establishing a dedicated local communication link. This allows for the secondary assignment of tasks to the lost drone without human intervention, effectively solving the problem of task interruption caused by signal interference and signal blind spots, thereby improving the continuity and integrity of drone field operations.
[0040] In one embodiment, the logic for determining that a drone has lost contact based on status data includes:
[0041] The ground base station monitors the online status of each UAV according to a preset heartbeat cycle (1s). If any UAV does not transmit data back for a preset number of consecutive heartbeat cycles and does not send an active offline command, the UAV is determined to be a lost UAV.
[0042] In one embodiment, the process of establishing the aforementioned preset search and filtering rules includes:
[0043] The search area is determined based on the last valid location coordinates of the missing drone; that is, the spherical area within a preset radius is the center of the sphere, with the last valid location coordinates of the missing drone as the center.
[0044] Within the search area, select drones that are currently without a task or performing a task with a lower priority than the missing drone, and whose remaining battery power is greater than a preset threshold (≥40%), as candidate drones;
[0045] Select the candidate drone that is closest to the center of the search area from all candidate drones and use it as the search drone.
[0046] By using multi-dimensional filtering rules to match search drones, and combining factors such as device communication status, remaining battery power, task priority, and spatial distance for comprehensive judgment, this avoids the problems of high-priority tasks being preempted and low-battery devices blindly executing search tasks, thereby achieving reasonable allocation of drone swarm resources and improving overall scheduling efficiency.
[0047] In one embodiment, the method by which the aforementioned search drone establishes a temporary communication base station accessible only to the missing drone via an onboard ad hoc network includes:
[0048] After retrieving the device's dedicated communication channel, device ID, and communication verification key from the ground base station, the communication parameters are bound.
[0049] Based on the bound communication parameters, a temporary communication base station is set up to actively broadcast directional networking signals to the outside world, and access is only granted to lost drones.
[0050] The temporary communication base station thus established adopts a dedicated frequency band and dedicated equipment binding mechanism, which only grants access permissions to the lost drones, shielding them from external equipment access and signal interference. This solves the problems of crosstalk, link chaos, and low matching accuracy in traditional temporary network communication, ensuring the stability and accuracy of task assignment in the scenario of lost contact.
[0051] In one embodiment, the reset logic includes:
[0052] Record search routes and search duration;
[0053] When the search duration reaches a preset threshold (e.g., 10 minutes), or when the search duration has not reached the preset threshold and the missing drone establishes communication with the search drone, a return-to-home command is triggered.
[0054] Control the search drone to return along the original search route.
[0055] Furthermore, after the search drone is reset, the temporary communication base station is shut down and temporary cached data, such as search routes and encrypted mission data packets, is cleared.
[0056] This allows for precise timing control and automatic reset and return-to-home mechanisms for search drones, effectively avoiding secondary problems such as meaningless drone lingering, power consumption, airspace conflicts, and equipment loss and crashes, thus ensuring the flight safety and equipment utilization rate of the swarm drones.
[0057] The following describes how to use an intelligent management system for drone mission delegation. (Refer to...) Figure 2 The method includes the following steps:
[0058] S1. Establish communication between the drone and the ground base station. The drone continuously transmits its status data (online status, positioning data, battery data and mission execution status) back to the ground base station.
[0059] S2. When it is determined that the drone is out of contact based on the status data (see the above logic for determining the drone out of contact based on the status data), the drone is determined to be a missing drone, and the last valid location coordinates, remaining unexecuted tasks, task priority and unique encrypted ID of the missing drone are determined.
[0060] S3. Using the last valid location coordinates of the missing drone as the center of a sphere, and a spherical area within a preset radius as the search area, match and search for drones within the search area using preset search and filtering rules (see the above process for establishing preset search and filtering rules).
[0061] In parallel, the ground base station retrieves the exclusive key ID to encrypt and package the remaining unexecuted tasks, and obtains the encrypted task data packet;
[0062] S4. After identifying the search drone, the ground base station sends an encrypted task data packet and a task relay delegation instruction to the search drone.
[0063] S5. Search drones establish temporary communication base stations that are only open to missing drones via airborne ad hoc network communication;
[0064] S6. Determine whether the missing drone has connected to the communication link of the temporary communication base station during the search period. If yes, proceed to S7; otherwise, proceed to S8.
[0065] S7. The search drone sends an encrypted task data packet to the missing drone. The missing drone decrypts the packet locally using its pre-stored private key, and then executes the remaining unexecuted tasks.
[0066] S8. The search drone executes the reset logic, resets to the original flight path, and restores communication with the ground base station.
