Description

technical field [0001] The invention relates to the technical field of plant protection drones. Background technique [0002] In recent years, with the continuous development and maturity of multi-rotor UAV technology, in terms of agricultural plant protection, the multi-rotor UAV operation method has greatly saved labor costs and improved operation efficiency compared with traditional manual operations. At the same time, it also ensures that operators are not harmed by pesticides; compared with traditional fixed-wing aircraft spraying large areas, multi-rotor UAV operations can significantly reduce flight costs. The downwash airflow generated by the rotating blades can blow away the leaves on the surface of the plants, so that the pesticides can be evenly applied to the whole crops, which effectively improves the application efficiency of pesticides and reflects the requirements of precision agriculture. Considering that the plant protection aircraft is operating in a larg...

Problems solved by technology

Most of the technologies now use the ground station system to generate the flight trajectory of the drone, use GPS to analyze the latitude and longitude of the surrounding edge points, and record the data to the ground station system, the ground station generates multiple target points based on the data, and saves the points , to form the flight path of the aircraft. This method has certain limitations to the region, and when the terrain is uneven, that is, when there are obstacles, the aircraft may not be able to avoid it in time, and there are potential safety hazards

Now some plant protection machines are equipped with obstacle detectors for detecting obstacles around agricultural plant protection drones, but when encountering obstacles, the drone sends them to the ground station through digital transmission, and then receives emergency obstacle avoidance instructions This delay may make it too late for the aircraft to evade and cause danger
