Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural unmanned aerial vehicles, and particularly relates to a device for supervising the flight operation of a plant protection unmanned aerial vehicle. Background Art

[0002] Plant protection drones are devices that use drone technology to protect crops. They use a payload spraying system and aerial sensor technology to monitor farmland conditions in real time and perform precise plant protection operations. For example, spraying pesticides and fertilizing crops can improve work efficiency and reduce environmental pollution. By using plant protection drones, farmers can better manage farmland and improve crop growth quality and yield.

[0003] Plant protection drones are unmanned aircraft controlled by wireless remote control or self-prepared programs; agricultural plant protection drones generally include medicine barrels filled with pesticides, and nozzles and spray heads connected to the medicine barrels in sequence; when agricultural plant protection drones fly over farmland, the pesticides in the medicine barrels are sprayed onto the crops in the farmland through the nozzles and spray heads in sequence to achieve plant protection. At present, some brands of drone manufacturers can provide some data management systems to provide information support when the drones are operating; some brands do not provide platforms and rely entirely on on-site operators to operate; the above two cannot guarantee whether the plant protection drones can meet the requirements of operation, and whether the flight trajectory meets the field area range standards, so a matching positioning and tracking system needs to be added.

[0004] In addition, when the plant protection drone is spraying pesticides, the amount of drift generated by the pesticide spraying is affected by the flight speed of the drone. The faster the speed, the more drift it generates. How to effectively monitor the operation effect of the plant protection drone and whether it meets the operation requirements requires the cooperation of third-party monitoring equipment. For this purpose, a monitoring system for pesticide flow needs to be added. Summary of the invention
