Problems solved by technology

Therefore, it is necessary to find the diffusion path of harmful gas as early as possible, so as to make plans in advance, personnel evacuation, fire protection and other measures, which requires detection in the initial stage of harmful gas diffusion, but at this time the pollutants mainly exist At high altitudes, ordinary ground stations cannot capture measurements, so a solution that can judge the spread of harmful gases in the environment is needed in the first place

Abstract

The invention relates to a harmful gas distribution and traceability detection method in an airspace range based on an unmanned aerial vehicle. An unmanned aerial vehicle system carrying a harmful gasrapid detection unit based on a tablet electrochemical sensor, a hovering height detection unit, a video image unit, a positioning unit and a wireless data transmission unit and a data receiving platform are used for carrying out harmful gas distribution and traceability detection in an airspace range; and harmful gas concentration data detected by the unmanned aerial vehicle at different positions and different heights are uploaded to the data receiving platform in real time, and on-site videos are transmitted in real time. Compared with a traditional ground station measurement mode, the measurement mode is improved from a plane to a three-dimensional mode, and the understanding of harmful gas distribution is greatly improved; by using the tablet electrochemical sensor, the weight of a detection device is greatly reduced, and the hang time of the unmanned aerial vehicle is favorably prolonged; and through construction of spatial vectors of harmful gas distribution, discovery and pre-judgment of harmful gas diffusion channels are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring, and in particular relates to an unmanned aerial vehicle-based harmful gas distribution and traceability detection method in the airspace. Background technique [0002] At present, the monitoring of harmful gases in the environment is mostly established on the ground. Through the widely distributed fixed harmful gas monitoring stations in the form of grids, combined with the measurement of meteorological parameters, the distribution, traceability, and diffusion of harmful gas concentrations can be mastered. [0003] When there is a large change in the concentration of harmful gases monitored at one of the many gridded monitoring stations, the data of adjacent stations will inevitably change accordingly due to changes in wind speed, wind direction and other meteorological conditions. . These characteristics can be used to obtain the real-time distribution of specific pollutants, a...
