Problems solved by technology

[0004] Technical defect 1: it is difficult to reach under complex terrain conditions;
[0005] Technical defect two: the problem of low response speed and limited monitoring range; and
[0006] Technical defect three: the problem of being unable to dynamically track and detect surrounding ambient gas parameters in real time
Although the above solution solves the technical problem of actively tracking and detecting the surrounding ambient gas parameters, however, when the rotor of the UAV system is working, it will discharge the surrounding ambient gas, and the gas will rise or fall through the discharge of the gas. In this process, the rotor of the UAV will cause eddy currents to the surrounding environment, so the above technical solution still has the following technical defects: the rotor changes the distribution of gas properties in the detection environment, resulting in inaccurate detection results

Abstract

The invention discloses a high altitude gas detection system and a detection method. The detection system comprises a mobile platform, an environmental gas collecting channel, multiple gas sensors and a gas flow controller, wherein the mobile platform comprises a cover body; the environmental gas collecting channel comprises a gas inlet, a containing cavity and a gas outlet which are sequentially arranged in a cut-through way; and the gas inlet and the gas outlet are respectively formed in the opposite ends of the cover body II, the containing cavity is enclosed by the cover body and cuts through the gas inlet and the gas outlet, the gas sensors are contained in the containing cavity of the environmental gas collecting channel, and the gas flow controller controls flow rate of the gas collected in the environmental gas collecting channel and guarantees that gas in the environmental gas collecting channel is renewed timely. The high altitude gas detection system and method precisely detect gas parameter distribution of a surrounding environment in real time, and the sensors are avoided from being interfered by an external environment, so that detection precision is improved, and life is prolonged.
