Abstract

The invention relates to an atmospheric pollutant wind-following monitoring system and monitoring method based on the multi-rotor unmanned aerial vehicle, an installation supporting rod used for installing a meteorological detection module is fixed to the center of the upper surface of a multi-rotor unmanned aerial vehicle box, and the meteorological detection module is fixed to the top end of theinstallation supporting rod; the meteorological detection module is connected with a serial port of an autopilot of the multi-rotor unmanned aerial vehicle through a wire. A hanging platform is arranged on the lower surface of a machine box; a 4G data transmission link sending terminal is fixed on the upper surface of the hanging platform, and the output terminal of the autopilot is connected with the input terminal of the 4G data transmission link sending terminal; the atmospheric pollutant detection module is fixed to the lower surface of the hanging platform, and the output terminal of theatmospheric pollutant detection module is connected with the serial port of the autopilot of the multi-rotor unmanned aerial vehicle. According to the invention, rapid and convenient pollution distribution detection can be carried out on a pollution detection area which is not suitable for manual detection, the safety of operators is ensured, and the labor cost is saved.

Description

technical field [0001] The invention relates to an air pollutant monitoring system based on a multi-rotor unmanned aerial vehicle, which belongs to the field of unmanned aerial vehicles and air pollution monitoring. Background technique [0002] In recent years, my country's industry has developed rapidly, and air pollution monitoring accompanied by industrial development has become an urgent problem to be solved. At the same time, 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. [0003] Air pollutant monitoring requires sampling and collection of pollutants, pollutant detection, pollutant location, and traceability of pollutants. Commonly used methods for measuring air pollutants include: meteorological observation towers, balloon observations, lidar, and manned fixe...

AI Technical Summary

Problems solved by technology

In these studies, the method considered by Ding Tao et al. uses local storage, the convenience of data transmission is limited, and the measurement process does not include meteorological parameters such as wind, which cannot provide a basis for further pollution monitoring and traceability plans. The method considered by Huan Hai and others uses the communication link between the UAV and the ground station, and the transmission distance has been improved, but it is still relatively limited, and it has not considered the influence of the airflow generated by the rotor on the measurement of wind speed by the ultrasonic anemometer from the mechanical structure. Interference; the method considered by Zhao Yutao and others uses fixed and mobile detection nodes for the two types of parameters of meteorology and pollution respectively. There are position differences between different nodes, which reduces the correlation between data
