Description

Technical Field

[0001] The present invention relates to the technical field of ozone detection, and in particular to a highly sensitive ozone monitoring sensor carried by an unmanned aerial vehicle. Background Art

[0002] Ozone is formed when nitrogen oxides and hydrocarbons in the atmosphere are exposed to the sun and undergo photochemical reactions. As one of the environmental pollution, ozone pollution has attracted the attention of more and more scholars. In response to the increasingly prominent ozone pollution, ozone monitoring has been included in the standards and carrying out monitoring is the first step in ozone pollution prevention and control. Before ozone prevention and control, we must first reduce the source and control the emission of precursors. Ozone is a typical secondary pollutant, and controlling the emission of its precursors is the key to governance. The precursors of ozone are mainly nitrogen oxides and volatile organic pollutants, and these two pollutants are also precursors of secondary fine particulate matter. Therefore, effectively controlling the emission of these two precursors is not only very important for controlling ozone pollution, but also for preventing and controlling PM2.5.

[0003] In the prior art, ozone concentration is often detected by an ozone detector. The ozone detector uses the principle of ultraviolet absorption method, uses a stable ultraviolet light source to generate ultraviolet light, uses a light wave filter to filter out other wavelengths of ultraviolet light, and only allows the wavelength of 253.7nm to pass through. After passing through the sample photoelectric sensor and then the ozone absorption cell, it reaches the sampling photoelectric sensor. By comparing the electrical signals of the sample photoelectric sensor and the sampling photoelectric sensor, and then calculating through a mathematical model, the ozone concentration can be obtained.

[0004] However, ozone detectors in the prior art are often used to collect ozone concentration on the ground, and the collected air samples are relatively concentrated, so there is room for improvement. Summary of the invention
