Agricultural spraying unmanned aerial vehicle based on internet of things

Abstract

The invention relates to an agricultural spraying unmanned aerial vehicle based on an internet of things. The unmanned aerial vehicle comprises a main body, a flight mechanism, a water intaking mechanism, a spraying mechanism, two vertically arranged upright posts, a first support rod, a second support rod and a buffer mechanism, wherein the flight mechanism is arranged at two sides of the main body; the water intaking mechanism is arranged at the upper part of the main body; the spraying mechanism is arranged at the upper part of the water intaking mechanism; and the buffer mechanism is arranged at the lower part of the main body. In a charging control circuit of the agricultural spraying unmanned aerial vehicle based on the internet of things, real-time monitoring protection is carried out on the battery through a first thermistor and a second thermistor; and real-time monitoring is carried out on the voltage of a battery through a first battery anode detection input end and a second battery anode detection input end, so that the battery charging reliability is ensured. Moreover, the movement direction of a clamping plate is controlled through rotation of a second drive motor, so that the cross section area of a water-passing pipe is adjusted; the flow velocity is controlled; a corresponding spraying range is formed on the ground; and large-range soil humidity is ensured.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle for agricultural spraying based on the Internet of Things. Background technique [0002] Water is one of the necessary conditions for the survival of crops. In the process of agricultural production, in order to ensure that the soil is in a suitable moist state, it is necessary to spray the soil regularly according to the weather and other conditions. Since the position of the traditional spraying mechanism is fixed and the cost is high, since the advent of the drone, people have installed the spraying mechanism on the drone, and the movement of the drone can automatically spray the crops, which saves spraying to a certain extent. cost. [0003] However, on the existing drones, due to the single and fixed structure of the spraying mechanism, the range of water sprayed on the ground by the spraying mechanism is very limited, and the drone needs to fly back and forth to water to ensure its watering ran...
