Agricultural spraying drones with pre-defined spraying areas

Abstract

An agricultural spraying drone with a pre-defined spraying area includes a flight body, a control unit, a power unit, and a spraying unit. The control unit, located within the flight body, includes an input module, a processing module, and a command module. The user uses drawing software to draw the spraying area boundaries, marking dimensions, departure position, flight direction, and obstacle areas based on cadastral data, generating a graphic file which is then input into the input module. The processing module automatically generates a spraying path based on the graphic file, and the command module generates control signals to drive the power unit and the spraying unit. The processing module also automatically adjusts the spraying height based on the crop height and avoids obstacles before returning to the original path. This invention significantly reduces manual setup time and improves spraying efficiency.

Claims

1. An agricultural spraying drone with a settable spraying area, comprising: a flight body; a control unit disposed within the flight body, the control unit comprising: an input module for receiving a graphic file; a processing module electrically connected to the input module for generating a spraying path based on the graphic file; a command module electrically connected to the processing module for generating a control signal; a power unit disposed on the flight body and electrically connected to the command module for receiving the control signal to drive the flight body to fly; and a spraying unit disposed on the flight body for performing spraying operations; wherein... The graphic file is generated by a drawing software based on cadastral data, which draws the boundary of a spraying area, indicates the size of the spraying area, indicates a departure position and a flight direction, and indicates at least one obstacle area.

2. The agricultural spraying drone with a settable spraying area as described in claim 1, wherein, This drawing software is a CAD drawing software.

3. The agricultural spraying drone with a settable spraying area as described in claim 1, wherein, The graphic file is selected from one of the following formats: DWG, DXF, or PDF.

4. The agricultural spraying drone with a settable spraying area as described in claim 1, wherein, The control unit can also record multiple sets of graphic files of the spraying area in a memory unit, so that users can select different spraying tasks.

5. The agricultural spraying drone with a settable spraying area as described in claim 1 further includes a remote controller, which is wirelessly connected to the control unit for manually controlling the flight of the drone or switching different spraying paths.

6. The agricultural spraying drone with a settable spraying area as described in claim 1, wherein, The processing module obtains the height of a crop through an altitude sensor installed on the flight body. The altitude sensor is one of an ultrasonic sensor, a laser ranging sensor, or an optical sensor.

7. The agricultural spraying drone with a settable spraying area as described in claim 1, wherein, After the flight body bypasses the obstacle area, the processing module records a deviation point and a return point, and controls the power unit to continue flying along the spray path from the return point.

8. The agricultural spraying drone with a settable spraying area as described in claim 6, wherein, The processing module automatically adjusts the spraying height of one of the flying bodies according to the height of the crop, and when the flying body encounters the obstacle area, it controls the power unit to bypass the obstacle area and then return to the spraying path.
