Problems solved by technology

[0003] Studies have shown that in order to ensure the application effect and reduce drift, aerial spraying operations at different heights require different sizes of droplet groups. During the spraying process, the UAV is affected by airflow fluctuations and man-made manipulation by the operator, so it cannot guarantee the consistency of the operating height in the whole process, and the fluctuation range of up and down often exceeds 1.5m or even reaches 3m. , it is impossible to guarantee both the operation effect and the environmental protection effect

Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] An agricultural aviation self-adaptive centrifugal atomization control system, including a DC motor 2, a centrifugal atomization turntable 4, the motor shaft is connected to the centrifugal atomization turntable 4, and the proximity switch 3 includes a bar-shaped metal mounted on the motor shaft and located on the motor shaft. The switch contacts on the shell, when the motor is running, the strip metal also rotates with the motor shaft, every time the proximity switch 3 is rotated, the output signal of the proximity switch 3 will experience a jump from low to high and then from high to low During the process, the single-chip microcomputer uses the external interrupt function to read the signal of the proximity switch, and records the number of times the bar-shaped metal turns over the switch contact per unit time, thereby calculating the current rotatio...

Abstract

The invention discloses an agricultural aviation self-adaption centrifugal atomization control system. The agricultural aviation self-adaption centrifugal atomization control system is used on an aviation operating centrifugal atomization nozzle, the rotation speed of a centrifugal atomization rotary disc can be adjusted according to the operating height of an unmanned aerial vehicle, and the size of fog drops changes along with changes of the operating height of the unmanned aerial vehicle, so that the aviation pesticide delivery operation achieves both the operating effect and environmental protection, and the purposes of improving the operating effect and reducing environmental pollution are achieved. In order to achieve the purposes, a motor, the nozzle and the centrifugal atomization rotary disc are used, an embedded type control system composed of a single-chip microcomputer and a peripheral circuit is designed, and the rotation speed of the atomization rotary disc is adjusted according to the current flight height of the unmanned aerial vehicle so as to change the size of fog drops.

Description

technical field [0001] The invention relates to an adaptive centrifugal atomization control system for agricultural aviation. The device is used for centrifugal atomization nozzles in aviation operations. The height of the drone's operation changes, so that the aerial spraying operation can take into account the operation effect and environmental protection, so as to achieve the purpose of improving the operation effect and reducing environmental pollution. Background technique [0002] Pesticide droplet drift is an important cause of environmental pollution, pesticide loss, and low effective utilization rate of pesticides. Due to people's increasing concern for environmental protection, controlling pesticide drift has always been a research focus in the field of plant protection machinery and pesticide application technology. Agricultural aviation operations often use high-concentration liquid medicines. During the process of atomizing these liquid medicines and moving from...
