1. The agricultural spraying uav uses long-distance remote control operation and flight control navigation to operate autonomously. It only needs to collect the GPS information of crops in the farmland before the spraying operation, and plan the route and input it to the internal control of the ground station. In the system, the ground station gives instructions to the aircraft, and the aircraft can carry the spraying device, complete the spraying operation autonomously, and automatically fly back to the take-off point after completion. While the aircraft is spraying, the progress of the spraying operation can be observed in real time through the display interface of the ground station.

2. The effect of agricultural spraying uavs is much higher than that of manual spraying. This is because the agricultural spraying uavs operate at 0.5-3 meters above the crops, and the airflow generated by the aircraft propellers blows the crop stalks at an angle of about 70 degrees. Turn the leaves of the crop over, so that the liquid medicine can enter different parts of the crop and the front and back of the leaves with the airflow, so that all parts of the crop can come into contact with the medicine. At the same time, aircraft spraying has a higher degree of atomization and smaller droplets, which can be more firmly attached to the surface of crops, which is not easy to cause waste and has a high utilization rate.

3. The low-volume spray is used, and it is a high-concentration fine spray. The droplets are smaller. During the operation, the pressure of the nozzle and the strong airflow of the aircraft propeller phenomenon are used to spray the medicine on the crops, which can be very Minimize medication use and water consumption.

4. The low-altitude spraying operation scale of agricultural spraying uavs can reach 1 mu of land per minute, and a small agricultural spraying uavs can spray 500 acres a day, while large agricultural spraying uavs can spray 1,500 acres a day land.
