Agricultural unmanned aerial vehicle spraying device and spraying method thereof

Abstract

The invention relates to an agricultural unmanned aerial vehicle spraying device and a spraying method thereof. The spraying device comprises an unmanned aerial vehicle spraying platform and a mobile ground supply station which is connected with the unmanned aerial vehicle spraying platform through an electric power and drug liquid transmission cable. The mobile ground supply station comprises a vehicle-mounted computer control device, a satellite navigation and positioning device, an automatic take-up and pay-off device and a continuous power supply and drug delivery device, wherein the vehicle-mounted computer control device is used for acquiring operation parameters and location information of the unmanned aerial vehicle spraying platform in real time and carrying out operation route planning, flight path deviation correction, navigation tracking and spraying parameter real-time adjustment on the unmanned aerial vehicle spraying platform so as to control single-machine or multi-machine cooperative spraying operations carried out between the unmanned aerial vehicle spraying platform and the mobile ground supply station; the satellite navigation and positioning device is used for measuring the location information of the mobile ground supply station; the automatic take-up and pay-off device is used for automatically taking up or paying off the electric power and drug liquid transmission cable; and the continuous electric power and drug delivery device is used for transmitting direct current and a drug liquid to the unmanned aerial vehicle spraying platform. The invention further provides a spraying method of the spraying device.

Description

technical field [0001] The invention relates to an agricultural unmanned aerial vehicle, in particular to an agricultural unmanned aerial vehicle spraying device capable of continuous power supply and drug delivery and a spraying method thereof. Background technique [0002] The loading capacity of UAV batteries and chemicals affects the spraying efficiency of the UAV platform and is a key indicator of the performance of UAV spraying equipment. Lithium-ion batteries are the main power supply for unmanned aerial vehicles. Lithium-ion batteries are consumables with limited battery life. As the number of charging and discharging increases, the possibility of safety problems (such as battery leakage, fire or even explosion) also increases. Using a container to load a large amount of liquid medicine on an unmanned aerial vehicle will easily affect the stability of the aircraft on the one hand. The unmanned aerial vehicle has a short battery life and needs to take off and land fr...
