Automatic chemical feeding system and method for plant protection unmanned aerial vehicle

Abstract

The invention discloses an automatic chemical feeding system and device for a plant protection unmanned aerial vehicle. The system comprises an airborne subsystem of the plant protection unmanned aerial vehicle and a ground base station; the airborne subsystem comprises a liquid level detection module and a chemical feeding control module; the output end of the liquid level detection module is connected with the chemical feeding control module; the liquid level detection module is used for detecting the liquid level of a chemical box of the plant protection unmanned aerial vehicle, and the chemical feeding control module is used for controlling the plant protection unmanned aerial vehicle to return to the ground base station when the liquid level of the chemical box of the plant protection unmanned aerial vehicle is lower than a preset value; the ground base station comprises an unmanned aerial vehicle parking detection device, a base station control center and a chemical feeding device; the output end of the unmanned aerial vehicle parking detection device is connected with the base station control center, and the output end of the base station control center is connected with the chemical feeding device. According to the automatic chemical feeding system and device for the plant protection unmanned aerial vehicle, real-time detection on the liquid level of the chemical box of the plant protection unmanned aerial vehicle can be achieved, when the liquid level in the chemical box is lower than the preset threshold value, the unmanned aerial vehicle is controlled to return to the base station for automatic chemical feeding, and the situation of chemical-free operation of the plant protection unmanned aerial vehicle is avoided.

Description

technical field [0001] The invention relates to an automatic dosing system and method for a plant protection drone. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft controlled by radio remote control equipment and its own program control device. There is no cockpit on board, but it is equipped with autopilot, program control device and other equipment; widely used Used in air reconnaissance, surveillance, communication, anti-submarine, electronic jamming, etc. [0003] With the continuous development of science and technology, drones have more and more applications, such as plant protection drones, as the name implies, are unmanned aircraft used for agricultural and forestry plant protection operations. This type of unmanned aircraft has a flying platform (fixed wing , single-rotor, multi-rotor), GPS flight control, and spraying mechanism are composed of three parts. The spraying operation can be realized through ground remote c...

Problems solved by technology

[0004] When the traditional plant protection UAV sprays pesticides, the traditional plant protection machine mainly relies on manpower to add pesticides, and the dosage supply plan depends entirely on the experience of the pilots. It does not realize the real-time detection of the amount of pesticides in the medicine box. In the working space environment, it is easy to misjudgment and cause the plant protection UAV to operate with an empty medicine box, or even to operate without medicine; this adds another waste to the plant protection operation, which was originally costly to fly.
