UNMANNED COMPLEX OF CHEMICAL SOIL EXPLORATION Russian patent published in 2022 - IPC B64C39/02 G01N27/12 

FIELD: analytical chemistry.

SUBSTANCE: invention relates to analytical chemistry, namely to measuring devices equipped with an unmanned aerial vehicle (hereinafter – UAV), which allows remotely identifying and quantifying volatile substances of various nature in the soil, including toxic substances. The unmanned complex contains a multi-rotor UAV, a video camera connected to the operator's control panel, a gas analyzer, a module of communication with the operator, an analytical chamber, a gas analyzer power module, modules for reading information and controlling the power of the gas analyzer. The UAV is additionally equipped with telescopic support posts equipped with sensors for contact with the surface of the landing site and a rod extension device that allows automatic extension of the support posts when landing on an uneven surface of the analyzed soil. The gas analyzer contains piezosorption-type sensors that are resistant to vibration, an open-type analytical chamber with sharpened edges for a tight fit to the soil.

EFFECT: accuracy of measuring the concentration of toxic substances in the soil increases.
