Spraying Drones [Professional]

 

Introduction

Unmanned aerial vehicle (UAV) variable-rate spraying technology, as the development direction of aviation for plant protection in the future, has been developed rapidly in recent years. In the actual agricultural production, the severity of plant diseases and insect pests varies in different locations. In order to reduce the waste of pesticides, pesticides should be applied according to the severity of pests, insects and weeds[1].

The application of pesticides and fertilizers in agricultural areas is of crucial importance for crop yields. The use of aircrafts is becoming increasingly common in carrying out this task mainly because of their speed and effectiveness in the spraying operation.[2]

A spraying drone was used to perform aerial spraying in a field using a ground control station. Before spraying, GPS waypoint and spraying control point information were sent to the ground station through the upstream port of the route planning system. After the UAV received the program-controlled instructions sent to data link by the ground station, it followed the predetermined route automatically. During the process of spraying, the UAV controlled the aircraft according to the predetermined GPS coordinates and sent a separate spraying control signal to the spray system. The spray system received the spraying control signal which started and stopped the work with feedback of the real-time status of the spray system to the host computer. The host computer returned the real-time GPS information and the status information of the spray system during flight back to the ground station via telemetry channels.
