Abstract

The invention provides unmanned helicopter pesticide applying operation automatic control system and method based on GPS (Global Positioning System) navigation, belonging to the field of agricultural technology. The main communication end of a flight control host machine is communicated with a GPS, and the main control output end is connected with the controlled end of a rotor flight system to be used for sending a navigation control signal to the flight system according to a preset air line and real-time position information transmitted by the GPS; an unmanned helicopter is also provided with a pesticide applying device and a pesticide applying control system, wherein the pesticide applying device comprises a pesticide box, a liquid pump, a spray rod and a spray head; the pesticide applying control system comprises a main control circuit, a communication module, a feedback module, a signal processing module and a power transformation module; the main control circuit is used for feeding back the state information of the pesticide applying system to the flight control host machine by the communication module; and the signal processing module is used for amplifying a pesticide applying control signal transmitted by the main control circuit into an electric signal and controlling the liquid pump to carry out pesticide applying operation. The system and the method can control the unmanned helicopter to flight according to the preset air line by the GPS and perform a spray task according to a preset GPS air line.

Description

technical field [0001] The invention relates to an automatic control system for pesticide application, in particular to an automatic control system for pesticide application by a drone based on GPS navigation, which belongs to the field of agricultural technology. The invention also relates to a GPS navigation-based drone spraying operation method. Background technique [0002] Compared with traditional manual pesticide application in the field, aerial spraying has significant advantages: high operating efficiency, zero harm of pesticides to operators, greatly reduced labor and labor intensity; less drift of fog droplets, strong penetration of fog flow on crops, The prevention and control effect is significantly improved; there is no need for a special take-off and landing airport, and the mobility is good. Aerial spraying technology provides the best operating platform for rapid and effective prevention and control of paddy field explosive diseases, insect pests and weeds,...
