[0034] like Figure 1 As shown, a collaborative UAV cluster path planning and scheduling system is disclosed, which includes: a multimodal perception unit, which is composed of a heterogeneous sensor array consisting of LiDAR, binocular vision and millimeter wave radar, and outputs a dynamically updated three-dimensional Gaussian mixture map; a decision control unit, which is used to implement a two-level optimization of mixed integer programming task allocation and artificial potential field path planning, and outputs adaptive PID control instructions with six redundancy;

Among them, LiDAR (10Hz scanning) provides centimeter-level point cloud, binocular vision (30fps) realizes texture recognition, millimeter-wave radar (77GHz) penetrates rain and fog, and data is fused through Kalman filtering (error <2cm). The upper-level MILP model (Gurobi solver) allocates tasks, and the lower-level potential field method (repulsive field coefficient σ=1.2) generates collision-free paths. The backbone node (TDMA time slot ≤5ms) ensures the transmission of key instructions, and the terminal node (802.11ax MU-MIMO) improves throughput.

Further, mixed integer programming: constructing an objective function minΣ(0.6t_ij+0.3e_ij )+0.1max(t_ij), solved by branch and bound method, artificial potential field improvement: repulsion weight w=2.5*(1+e^(-d / 1.2)), when the obstacle distance d<5m, the weight increases exponentially, LSTM prediction network: input 10 frames of historical trajectory (100ms / frame), output the probability distribution map of the trajectory in the next 1s, MILP model combined with slack variables, reducing computational complexity by 30%, improving task allocation efficiency, adaptive repulsion field weight to avoid local optimal traps, dynamic obstacle avoidance capability, predictive conflict resolution, and can identify potential collision risks 300ms in advance.

Furthermore, wind field data (collected by ultrasonic anemometer) is used for point cloud coordinate correction. The spatiotemporal alignment module uses hardware synchronization signals (PPS pulses) to unify the sensor clock, with a delay jitter of <1ms. The meteorological anti-interference capability still maintains 85% perception accuracy in a level 6 wind / rainstorm environment, cross-platform compatibility, and supports seamless access to sensors from different manufacturers.

[0039] As a preferred embodiment, the energy management module includes: a wireless charging scheduler capable of calculating the optimal service radius R_opt = √(P_txη / (πP_th)); a gliding strategy generator: calculating the optimal gliding angle according to the atmospheric density ρ(h):

[0040] θ_glide = arctan[(C_D / C_L)(1+2W / (ρ(h)S√(C_L2+C_D2)))] Furthermore, the angle of attack is adjusted in real time based on the atmospheric density lookup table (US Standard Atmosphere 1976 model) to calculate the service radius, optimizing charging efficiency. This reduces the density of wireless charging stations by 40%, achieves a breakthrough in glide energy savings, and reduces energy consumption during level flight by 35%.

[0042] (a) The improved Voronoi diagram is used to segment the 3D space, and the segmentation weight includes the energy consumption factor;

[0043] (b) Quantum genetic algorithm optimization path, the chromosome encoding contains polar coordinates represented by 3 qubits

[0044] (c) Dynamic conflict resolution: Apply time dilation Δt = kd / (v_max - v_curr) or spatial offset Δp = R(1-e^(-t / τ))n to the conflicting paths; improve the Voronoi diagram, introduce energy weighting factors, improve the efficiency of three-dimensional space segmentation, and increase the speed of Voronoi diagram generation by 5 times.

Physical constraints are aligned, and the heading angle change Δθ2 reduces ineffective maneuvers by 30%.

[0047] A computer-readable medium storing the method as described in claims 6-7 integrates a federated learning framework, adopts θ_global = Σ(θ_local_i + Laplace(0,b)), and implements differential privacy protection. It has a built-in Gazebo / ROS2 digital twin interface and supports real-time simulation of 150 nodes. In particular, the federated learning framework is adopted, Laplace noise is added during parameter aggregation, the privacy budget ε = 0.5, and millisecond-level synchronization between the Gazebo simulator and the physical controller is achieved through the DDS protocol. The differential privacy mechanism reduces the data leakage risk to <5%, and supports stress testing of a 150-node cluster in a digital twin environment.

[0048] Detailed explanation of the workflow of the present invention:

[0049] After the system is started, it first collects environmental data in real time through a multimodal sensor array, LiDAR / vision / millimeter wave radar, and performs spatiotemporal alignment through an extended Kalman filter to construct a dynamically updated 3D Gaussian mixture map. At the same time, meteorological sensors compensate for the impact of wind field / precipitation on perception; after the decision layer receives the task instruction, the upper-level mixed integer programming engine (MILP) combined with Q-learning dynamic priority weights completes the 50-node task allocation and generates the spatiotemporal constraint matrix within 50ms, and the lower-level improved artificial potential field method plans the initial path based on the repulsive field model (σ=1.2); the path planner uses a quantum genetic algorithm to encode 3-qubit polar coordinates and optimize the three-dimensional voxel space (5m×5m×3m grid), predicts the obstacle trajectory in the next 1s through the LSTM network, and implements time dilation (Δt=kd / Δv) or spatial offset (Δp=R(1-e^(-t / τ)) on the conflicting path in real time; the control layer uses six redundant The system uses a high-speed actuator and an adaptive PID (Lyapunov exponential feedback) with a disturbance observer, outputting control commands at a 10Hz frequency, while dynamic voltage scaling (DVFS) optimizes energy consumption based on flight status. The communication network uses TDMA backbone nodes with a time slot of ≤5ms, and is hybrid-networked with 802.11ax terminal nodes. A lightweight Byzantine fault-tolerant protocol (an improved PBFT) is used to achieve a 95% data integrity rate under 20% node failures. The energy management module calculates the optimal glide angle θ_glide based on the atmospheric density model (USSA-76) and dynamically schedules the service radius of wireless charging stations. Full-process data is synchronized to the Gazebo / ROS2 digital twin platform for 150-node extreme scenario verification. The federated learning framework, with differential privacy ε=0.5, continuously optimizes parameters to form a closed-loop workflow of "perception → decision → execution → verification → iteration", achieving a 200ms dynamic obstacle avoidance response, an 89% task completion rate, and 28% overall energy savings.

[0050] Example 1: Forest fire prevention work

[0051] 1. Hardware Configuration

[0052] Drone platform: The quadrotor maintains a 350mm wheelbase and features a carbon fiber frame (treated with a high-temperature-resistant coating). The sensor module includes a thermal imaging camera (FLIR Tau2, 640×512 resolution, temperature range -40°C to 550°C); a gas sensor (MQ-2 smoke sensor + CO detection module); and a Livox Mid-40 LiDAR (which penetrates smoke and generates real-time 3D terrain maps).

[0053] Mission payload: Fire extinguishing bomb bay (500g payload, capable of carrying four chemical fire extinguishing bombs); emergency material delivery device (maximum delivery weight 300g); and communication module, which consists of a satellite communication relay (Beidou short message module, supporting communication in areas without network access) and an enhanced image transmission system. The enhanced image transmission system uses a 2.4GHz + 5.8GHz dual-band transmission range of 5km (in complex terrain).

[0054] Ground facilities: Mobile command station, which integrates the QGC ground station and fire analysis system; portable charging station, which can support fast battery replacement (battery replacement can be completed in 5 minutes).

[0055] 2. Software parameter configuration

[0056] Path planning: Fire spread model integration: Predict fire paths based on meteorological data (wind speed, humidity) 3. Typical workflow;

[0057] Emergency obstacle avoidance parameters: conflict_zones = predict_fire_spread(wind_speed,humidity)

[0058] safe_altitude = max(50m,2×flame_height) #Safe flight altitude calculation

[0059] Quantum genetic algorithm weight adjustment: ω1 = 0.5 (fire urgency), ω2 = 0.3 (endurance), ω3 = 0.2 (terrain complexity);

[0060] Communication protocol: includes anti-interference mode, which can automatically switch to TDMA backbone node to dominate communication in smoke environment; emergency channel, which reserves 400MHz frequency band for Beidou short message transmission (packet loss rate <5%).

[0061] 3. Forest fire prevention workflow

[0062] Phase 1. Fire reconnaissance phase

[0063] Multi-drone coordinated launch: Three drones form a formation. The master drone is equipped with a thermal imaging camera (FLIR Tau2) to scan the surface temperature (accuracy ±2°C). Slave drone 1 uses LiDAR to build a 3D map of the fire scene (updated at 1Hz). Slave drone 2 uses an MQ-2 sensor to monitor the CO concentration in real time (threshold >50ppm triggers an alarm).

[0064] Data fusion and labeling: The onboard computer (Jetson Nano) integrates heat source distribution, terrain data, and gas concentrations, uses the ORB-SLAM algorithm to mark the fire boundary (error <3m), and predicts the fire spread path (emergency mode is activated when wind speed >8m / s).

[0065] Real-time backhaul: Fire scene coordinates and temperature gradient maps are synchronized to the ground command station through 5.8GHz image transmission (5km range) and Beidou short message dual channels.

[0066] Phase 2. Firefighting mission execution phase

[0067] Dynamic task allocation: The MILP model uses minΣ(0.4t_ij+0.3e_ij+0.3d_fire) as the objective function to allocate fire bomb throwing (covering a radius of 8m) and beacon delivery tasks. The quantum genetic algorithm optimizes the flight path (avoiding updraft areas).

[0068] Anti-disturbance control: Under heat wave disturbances, the adaptive PID with sliding mode observer (overshoot <3%) adjusts the motor speed in real time, and combined with DVFS, dynamically adjusts the voltage (energy consumption is reduced by 15%).

[0069] Firefighting operation: After arriving at the target point, the fire extinguishing magazine solenoid valve is triggered (response time 0.2s), the positioning beacon (UWB accuracy ±0.1m) is released simultaneously, and the firefighting effect is verified by LiDAR.

[0070] Phase 3. Emergency return and maintenance

[0071] Return trigger: When the battery voltage is less than 14.8V or the fuselage temperature is greater than 60℃ (for 10 seconds), it will automatically switch to TDMA backbone communication mode and return to home at a safe altitude (≥50m).

[0072] Quick maintenance: After landing, use compressed air to cool the motor (cool down to 40°C in 2 minutes), clean the thermal imaging lens with anhydrous ethanol (to prevent smoke and dust adhesion), and check the carbon brush wear (limit value <3mm).

[0073] Data review: A federated learning framework (differential privacy ε = 0.5) analyzes task data, optimizes the fire prediction model, and iteratively updates the cluster system.

[0074] Implementation Results: The forest fire prevention workflow begins with a three-aircraft formation coordinated reconnaissance: the master aircraft uses thermal imaging to accurately scan the fire scene's temperature distribution, slave aircraft 1 utilizes LiDAR to build a 3D terrain model, and slave aircraft 2 monitors CO2 concentrations in real time. This data is fused via Jetson Nano to mark the fire boundary and predict the spread path. During the firefighting phase, the MILP model dynamically allocates tasks, a quantum genetic algorithm optimizes the bombing path, and adaptive PID control is combined to mitigate heat wave disturbances, accurately dropping fire bombs (with an accuracy of ±5m) and navigation beacons. Low battery voltage or high temperature triggers an emergency return, ensuring stable communication via dual TDMA / Beidou channels. Upon return, the motor is rapidly cooled and the sensor is cleaned. Federated learning analyzes the task data and optimizes the algorithm. This entire process reduces fire response time to 2.5 minutes and improves firefighting efficiency by 67%.
