Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to an intelligent detection and early warning device for plant protection UAVs based on hyperspectral reconstruction technology. Background Art

[0002] Traditional plant protection operations rely on manual backpack sprayers or ground machinery, which have problems such as low efficiency, high labor intensity, and pesticide drift pollution. Drones, with their low-altitude flight and precise control characteristics, are deeply in line with plant protection needs and have become a key technology for the transformation and upgrading of modern agriculture.

[0003] However, existing plant protection drones have some shortcomings that need to be improved. Specifically, current rice blast monitoring and pesticide management technologies have many bottlenecks. In the monitoring process, the hyperspectral imaging equipment on the drone is difficult to balance spectral and spatial resolution, and the spectral differences in the pixel area interfere with image fusion, resulting in a classification accuracy of normal and damaged rice of less than 90%, making it difficult to distinguish the extent of the disease; full-band data transmission is prone to delays and losses, and decision-making information is difficult to obtain in a timely manner in complex terrain. In terms of drone path planning, the mainstream model relies on preset routes and cannot dynamically adjust flight parameters according to the disaster situation. Repeated spraying or omissions occur frequently, and the operating efficiency is more than 50% lower than the new solution. It also has weak adaptability to complex environments such as irregular fields and obstacles, and often requires manual intervention. In addition, in pesticide spraying technology, fixed nozzles cannot spray evenly. Summary of the Invention

[0033] The working principle of the present invention is as follows: the camera 2 carried by the drone starts working and collects hyperspectral data of the rice field according to the preset flight path. The hyperspectral data acquired by the camera 2 contains the spectral information and spatial information of the rice. These data are transmitted to the hyperspectral reconstruction and image processing module inside the drone body 1 through a data line. The hyperspectral reconstruction and image processing module uses innovative physical models and deep learning hyperspectral reconstruction technology to process the collected hyperspectral data. The module integrates spectral and spatial information, eliminates the interference caused by spectral differences in pixel areas in the image, and generates high-resolution hyperspectral images. Through image analysis and processing, the classification accuracy of normal and damaged rice is improved to 98.28%. At the same time, the degree of disease is accurately identified, and the accuracy of disaster degree identification reaches 98.79%. The processed rice disaster image and classification information, disease degree information and other data are stored in the module and transmitted to the path planning module and algorithm model optimization module in real time. After receiving the rice disaster information and GPS information transmitted by the hyperspectral reconstruction and image processing module, the path planning module integrates and analyzes this information, combines the current position and posture information of the drone, and the preset flight parameters to determine the areas that need to be monitored and sprayed. With the help of the deep reinforcement learning model, the path planning module analyzes the disaster situation and terrain in real time. Through the deep reinforcement learning algorithm, according to the degree of rice damage, terrain undulations, and obstacle classification, the path planning module During the flight, the module continuously receives new information and adjusts the flight path in real time to avoid repeated spraying or omissions, ensuring that the drone can cover the entire rice field efficiently and accurately. When spraying, the second motor 141 drives the second shaft 142 to rotate, and the first sprocket 151 on the second shaft 142 drives the second sprocket 153 to rotate through the chain 152. The second sprocket 153 drives the stirring frame 154 to rotate in the medicine box 7 to stir the liquid medicine to mix it evenly and avoid precipitation and stratification affecting the spraying effect. When the second shaft 142 rotates, it drives the rotating disk 181 to rotate, and the multiple cylinders 1811 on the rotating disk 181 push the waist-shaped frame 182 The transmission gear block 1821 moves, driving the waist frame 182, which in turn drives the medicine box 7 and the spray head 11. When the cylinder 1811 contacts the limit gear block 1822, the waist frame 182 resets, and the process repeats, causing the medicine box 7 and the spray head 11 to move back and forth. As the medicine box 7 and the spray head 11 move back and forth, the variable pump 8 and the solenoid valve 10 are controlled in real time. The variable pump 8 pumps the liquid medicine from the medicine box 7 at a preset flow rate and delivers it to the spray head 11 through the delivery pipe 9. The solenoid valve 10 controls the opening and closing of the spray head 11 and the spraying amount as needed, achieving millimeter-level variable spraying, achieving a pesticide spraying accuracy of 98.85%, and improving the effective utilization rate by 88.79%. The communication and data transmission module transmits the drone's collected hyperspectral data, processed image information, path planning results, pesticide spraying status, and other data in real time to the ground control terminal using sensitive band transmission technology. This reduces data transmission volume and mitigates the risk of delays and loss. Ground control terminal staff use the received data to monitor and analyze rice growth, pest and disease occurrence, and pesticide spraying effectiveness in real time. Based on the analysis results, they promptly adjust the drone's flight parameters and spraying plans, providing a scientific basis for subsequent agricultural production decisions.
