Low-dosage environment-friendly intelligent side spraying device for obstacle avoidance of plant protection unmanned aerial vehicle

Abstract

The invention provides a low-dosage environment-friendly intelligent side spraying device for obstacle avoidance of a plant protection unmanned aerial vehicle from the perspectives of protecting the environment, reducing the dosage of pesticides and improving the energy conservation and environmental protection aiming at the problem that fog drops around obstacles cannot realize sufficient coverage when the unmanned aerial vehicle avoids the obstacles. The device comprises an intelligent spraying system, an intelligent control system and an intelligent monitoring system, static and variable spraying technologies are adopted, meanwhile, the device can intelligently adjust the spraying angle and the inclination angle of a spray head according to the size of an obstacle avoidance detouring area of the unmanned aerial vehicle, the relative position of the unmanned aerial vehicle and an obstacle and the posture change of the unmanned aerial vehicle, it is ensured that the spray head always faces the target area and the fog drop range completely covers the target area, the same plant protection effect is achieved, meanwhile, the pesticide use amount is reduced, the over-spraying and leakage spraying phenomena are reduced, the pesticide utilization rate and environmental protection performance are improved, and the device has the advantages of being low in pesticide use amount, high in utilization rate, good in energy-saving and environmental protection performance, compact in structure, wide in application range and the like.

Description

technical field [0001] The invention relates to a plant protection unmanned aerial vehicle, in particular to a low dosage environment-friendly intelligent side spray device for enhancing the coverage of droplets around obstacles when the plant protection unmanned aerial vehicle avoids obstacles, and belongs to the technical field of agricultural plant protection. Background technique [0002] In recent years, China's agricultural plant protection drones have developed rapidly, and more than 95% of the country's agricultural aviation technology is used for plant protection operations. China's farmland environment is relatively complex, and the operating plots are small, scattered and irregular in shape. Compared with traditional ground-walking plant protection equipment, UAVs have obvious advantages in terms of flexible terrain adaptability and high efficiency. [0003] Obstacles in Chinese farmland can be divided into micro-obstacles (such as wires, stay cables), small and m...

AI Technical Summary

Problems solved by technology

[0005]In order to solve the above technical background, when the traditional plant protection UAV avoids obstacles and circumvents, the fog droplets are not enough to completely cover the obstacle avoidance and circumvention areas, and manual supplementary spraying is required to ensure The effect of plant protection operations, the problem of high labor and time costs, the present invention proposes a low-dose environment-friendly plant protection UAV obstacle-avoiding intelligent side spray device to increase the droplet deposition in the obstacle-avoiding detour area and improve the obstacles Insufficient coverage of surrounding fog droplets
