Problems solved by technology

Judging from the current spraying situation, it is difficult to meet this demand, and the multi-rotor UAVs currently on the market have a big battery life problem, and generally can only fly for tens of minutes, which greatly limits the breadth of operations , it is very unrealistic to carry out point-to-point flight precision operations
At the same time, most of the precise collection of field ground information and cloth samples is done manually in the field, and there is currently no drone for similar work

Embodiment 1

[0058] An unmanned aerial vehicle capable of arbitrarily taking off and landing in the field, including a main body 1 and an elevating undercarriage 2, the elevating undercarriage is used to support the main body above the plants;

[0059] The main body is equipped with a spraying device 3 and / or an airborne vision sensor 4 and / or an airborne three-way wind speed sensor 5 .

[0060] The spraying equipment, the airborne vision sensor and the airborne three-way wind speed sensor can be installed on the main body separately or two or three of them can be installed according to actual operation needs.

[0061] The main body is provided with a flight attitude control module, a wireless data communication module, a data processing module and a navigation and positioning module, as well as a ground station for controlling the drone and sending and receiving information.

[0062] Preferably, the main body is provided with an extension frame, and the medicine dispensing equipment and / or ...

Embodiment 2

[0066] An operation method for unmanned aerial vehicle field intermittent operation, comprising the following steps:

[0067] Step 1. Collect and analyze remote sensing information on the working farmland, determine the target point that requires precise operation, and transmit the position information of the target point to the navigation and positioning module of the drone;

[0068] Step 2. The UAV flies to the target location according to the target location information received by the navigation and positioning module, and the UAV hovers; when taking off, the landing gear is in a raised state;

[0069] Step 3, the lifting landing gear is stretched out, and the extension length is longer than or equal to the height of the plant; the drone lands, the lower part of the lifting landing gear touches the ground, supports the main body above the plant, and the drone stops steadily;

[0070] Step 4, control the field work on the target target position;

[0071] Step 5. After the ...

Abstract

The invention discloses an unmanned aerial vehicle capable of arbitrarily taking off and landing in the field and an operation method thereof, wherein the unmanned aerial vehicle capable of arbitrarily taking off and landing in the field includes a main body and an elevating landing gear, which is used for elevating and landing the unmanned aerial vehicle. The main body is supported above the plants; the main body is equipped with pesticide application equipment and / or airborne vision sensors and / or airborne three-way wind speed sensors. According to the actual needs of the operation, the present invention can make the UAV accurately land on the target position in the farmland and make the UAV fuselage be at the plant canopy or above by adjusting the extension length of the UAV lifting and landing gear, and then The UAV stopped and started to work, achieving the purpose of precise operation.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to an unmanned aerial vehicle capable of arbitrary take-off and landing operations in the field and an operation method thereof. Background technique [0002] The current plant protection drones are mainly used to spray pesticides on large-area forests or farmland grains or economic crops. They often apply pesticides indiscriminately to an entire plot, but the pests and weeds in each area are different. , some require precise and quantitative application of pesticides, and some do not require pesticide application at all. Judging from the current spraying situation, it is difficult to meet this demand, and the multi-rotor UAVs currently on the market have a big battery life problem, and generally can only fly for tens of minutes, which greatly limits the breadth of operations. , it seems very unrealistic to carry out point-to-point flight precision operations. At the same time, most of ...
