Abstract

The invention discloses a liquid level measuring device of a plant protection unmanned aerial vehicle. The liquid level measuring device comprises a detecting unit, a signal converting unit, a signaloutput unit and a control system. The detecting unit is used for detecting the liquid level of a liquid pesticide in a pesticide tank of the plant protection unmanned aerial vehicle and transmits information in the form of electric signals to the signal converting unit. The signal converting unit is used for converting the electric signals output by the detecting unit into binary codes and transmitting the binary codes to the signal output unit. The signal output unit is used for outputting the binary codes to a central processor. The control system is used for controlling the activation and stop of each sensor and controlling the time when the signal output unit transmits the binary codes to the central processor. By means of the liquid level measuring device, the liquid level of the pesticide tank can be detected, the working conditions of pesticide spraying openings are controlled according to feedback information of the sensors, excessive pesticide applying is avoided, and work efficiency and quality are improved.

Description

technical field [0001] The invention relates to a liquid level measuring device, in particular to a plant protection drone liquid level measuring device. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft operated by radio remote control equipment and its own program control device, and can realize automatic driving. It is widely used in aerial reconnaissance, surveillance, communication, electronic interference and other fields. . [0003] With the continuous development of science and technology, the application of unmanned vehicles in agriculture and forestry is becoming more and more extensive. Plant protection UAV is a practical application of modern unmanned aircraft for agricultural and forestry plant protection operations. This type of unmanned aircraft has a flight platform (fixed wing, single rotor, multi-rotor), GPS flight control, spraying mechanism It is composed of parts, and the spraying operation can be realized t...
