【摘要】 为扩大常规环境监测的空间范围,并在大气污染应急事件中起到重要的监测和预警作用,本研究将无人机与便携式FTIR光谱仪有机结合,对监测区域内的气体红外光谱数据进行测量,并通过数据传输模块将数据从无人机发送至地面接收端。将接收到的红外光谱进行定量分析,反演出该区域内空气中各污染气体的浓度,并结合地理信息系统(GIS)技术实现气体浓度数据的3D可视化展示。初步监测实验结果验证了该方法在高效性和准确性方面的优势,且该系统灵活便携,有望在环境监测和应急响应等方面得到广泛应用。更多还原

【Abstract】 To expand the spatial coverage of conventional environmental monitoring and play an important monitoring and early warning role in air pollution emergencies, a drone is combined with a portable FTIR spectrometer in this work to measure the infrared spectral data of gases in the region. The data from the drone is sent to ground receiving end through a data transmission module, and then the received infrared spectra are quantitatively analyzed to invert the concentrations of various pollutant gases in the air and combined with geographic information system(GIS) technology to achieve a 3D visualization of the gas concentration data. Preliminary monitoring experimental results have verified the advantages of this method in terms of high efficiency and accuracy. Moreover, the system is flexible and portable, and is expected to be widely used in environmental monitoring, emergency response, and other fields.更多还原
