Full-autonomous flight system and method of unmanned aerial vehicles for plant protection

Abstract

The invention discloses a full-autonomous flight system and method of unmanned aerial vehicles for plant protection. The system comprises a large standard parcel, at least one unmanned aerial vehicle for plant protection and an automatic battery and pesticide chest replacement platform, wherein the at least one unmanned aerial vehicle for plant protection comprises a power supply module, a flight control module, a communication module, a timing module, an image acquisition module, a battery power detection module and a pesticide chest pesticide quantity detection module; the automatic battery and pesticide chest replacement platform comprises a platform body, a power supply, a control unit, at least one battery storage area, at least one unmanned aerial vehicle taking-off and landing area and at least one pesticide chest storage area. The method comprises steps as follows: the large standard parcel is surveyed through an unmanned aerial vehicle for surveying and mapping, and flight routes are planned and divided for multiple unmanned aerial vehicles for plant protection; when the battery power detection module detects that batteries are in low power or the pesticide chest pesticide quantity detection module detects that pesticides are insufficient, the corresponding unmanned aerial vehicle for plant protection flies to the corresponding automatic battery and pesticide chest replacement platform for replacement of batteries or a pesticide chest. The unmanned aerial vehicles for plant protection fly cooperatively, the situation that multiple unmanned aerial vehicles for plant protection collide in the inward journey is avoided, the batteries and the pesticide chests of the unmanned aerial vehicles for plant protection are automatically replaced, time and labor are saved, and the efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a fully autonomous flight system and method of a plant protection unmanned aerial vehicle. Background technique [0002] With the development of drone technology, plant protection drones have also been widely used in agriculture. At present, for the plant protection operations of standardized large plots, a single plant protection drone is still used for flying defense operations. Even if multiple plant protection drones are used for operations, the standardized large plots must be divided, and each plant protection drone UAVs have to carry out surveying and mapping once, and the procedure is cumbersome; in addition, due to the limitation of battery technology, the battery life of the general plant protection drone system is less than one hour, so it is impossible to continue to work for a long time, which requires During the process, the battery is ...
