Atmospheric monitoring method and system based on multi-rotor unmanned aerial vehicle

Abstract

The invention provides an atmospheric monitoring method and system based on a multi-rotor unmanned aerial vehicle, and relates to the technical field of atmospheric monitoring. The method comprises the following steps: converting range information into a three-dimensional map library and importing the three-dimensional map library into the unmanned aerial vehicle; dividing the monitoring area into a target area according to a preset rule, and searching a three-dimensional map corresponding to the target area in the three-dimensional map library; and performing coordinate conversion on the obstacle position to obtain an obstacle coordinate in the three-dimensional map library; distributing the unmanned aerial vehicles according to the number of the target areas, and planning a flight monitoring route in the corresponding three-dimensional map according to the target area range and the obstacle coordinates; and acquiring atmospheric state parameters and remote sensing images of the target area, and transmitting the atmospheric state parameters and the remote sensing images to a ground station in real time. The low application efficiency of the unmanned aerial vehicle due to the fact that the working capacity of the single unmanned aerial vehicle is limited by factors such as endurance time, load weight and environmental conditions is avoided, and therefore the atmospheric monitoring task is completed through the unmanned aerial vehicle so as to comprehensively know the dynamic condition of the atmospheric environment.

Description

technical field [0001] The invention relates to the technical field of atmospheric monitoring, in particular to an atmospheric monitoring method and system based on a multi-rotor unmanned aerial vehicle. Background technique [0002] In recent years, my country's industry has developed rapidly, and the air pollution caused by industrial development has become more and more serious. A variety of complex air pollutants produced by fuel combustion, industrial production, and transportation not only affect the air environment of the city, but also cause great damage to the health of urban residents, and even induce major physical diseases. Therefore, air pollution monitoring is becoming more and more important. [0003] Commonly used methods for measuring air pollutants include: meteorological observation towers, balloon observations, lidar, and manned fixed-wing aircraft. A large number of methods realize atmospheric observation by setting up observation stations on the groun...

Problems solved by technology

[0004] The purpose of the present invention is to provide an atmospheric monitoring method and system based on a multi-rotor UAV, in order to improve the actual environment in the prior art due to the different actual observation areas, and the operating capability of a single UAV is limited by the endurance time, load weight, etc. Due to the limitation of environmental conditions and other factors, the application efficiency is low, and it is difficult to complete increasingly complex tasks, and it is difficult to timely and comprehensively understand the dynamic status of the atmospheric environment and issue pollution warning information.
