Description

Technical Field

[0001] The invention relates to a construction pollution detection device and method for an unmanned aerial vehicle, belonging to the technical field of green construction of substations. Background Art

[0002] The construction process is accompanied by the generation of a variety of pollutants, among which dust and exhaust gas that can be emitted into the atmosphere have the most serious impact on construction workers and surrounding residents, threatening people's health at the very least and affecting their lives at the worst.

[0003] In order to effectively reduce construction pollutant emissions and improve the green construction capabilities of projects, it is necessary to clearly understand the pollutant emissions at the construction site. The current main pollutant emission detection method only uses fixed pollutant emission detection methods to measure pollutant emissions near the point, such as using dust monitoring sensors to measure regional dust conditions. However, when the dust source is far away from the sensor, it is difficult to effectively measure the accurate dust distribution. Construction waste gas escapes in the air, and the measured value at a certain point cannot reflect the overall site waste gas properties.

[0004] Using drones to detect pollutant emissions at construction sites can effectively reduce the drawbacks of fixed pollutant emission monitoring that can only measure the pollution situation at a specific location, thereby achieving flexible detection of large-scale construction sites. However, drones carrying dust and gas sensors to detect pollutants at construction sites have good maneuverability and flexibility, but the drone rotors will generate airflow to image the gas distribution around the sensor. For dust detection, it can even blow up ground dust to form new dust. For gas detection, the wing airflow blows away the gas near the sensor, making it impossible to measure the accurate gas content. Summary of the invention
