Unmanned aerial vehicle with PM2.5 air content detection function

Abstract

The invention discloses an unmanned aerial vehicle with a PM2.5 air content detection function, and belongs to the technical field of unmanned aerial vehicles. According to the scheme, when the PM2.5 content in air is detected, the unmanned aerial vehicle is released to fly towards the air gradually, due to the fact that pressure in the air extrudes downwards, a diaphragm is opened, and the air flows into a PM2.5 content detection box; when the PM2.5 content detection box is full of air and the parallel monochromatic light enters the PM2.5 content detection box, the influence of surrounding scattering and absorption of particles in the air is generated, the PM2.5 content is judged according to the color change of photolysis of the silver chloride powder in the PM2.5 content detection box, chlorine is generated after the silver chloride powder is subjected to photolysis reaction, and the content of the PM2.5 is detected. The silver chloride powder is added into the deformation film, so that the deformation film expands, the movable rod is driven to extrude one end of the built-in deformation balloon, the bisoxalate solution and the hydrogen peroxide solution in the built-in deformation balloon penetrate through the permeation film to generate a fluorescence reaction, and at the moment, the PM2.5 content in the air is further known according to the brightness degree of the silver chloride powder.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, and more specifically, relates to an unmanned aerial vehicle with the function of detecting PM2.5 air content. Background technique [0002] The application fields of unmanned aerial vehicles are constantly expanding. Both industrial drones and consumer drones have made great progress, especially small and micro unmanned aerial vehicles represented by multi-rotor unmanned aerial vehicles. Unmanned Aerial Vehicle ("UAV") is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device. UAV is actually a general term for unmanned aerial vehicles. From a technical point of view, it can be divided into: Unmanned fixed-wing aircraft, unmanned vertical take-off and landing aircraft, unmanned airship, unmanned helicopter, unmanned multi-rotor aircraft, unmanned umbrella wing aircraft, etc. With the development of unmanned aerial vehicle tech...

Problems solved by technology

[0003] At present, in the process of detecting the PM2.5 content in the air, most of them sample the air on the ground for detection, but the sampling of the PM2.5 content in the high-altitude air is relatively cumbersome, and at the same time, it is necessary to compare the sampled air in the future Calculation, more procedures, reducing work efficiency
