Air Pollution Monitoring Based on Wide Band Infrared Spectrum Telemetry

大气环境受到污染,会造成地区生态失衡、损害人身体健康,所以需要对污染气体进行监测。为此提出基于宽谱段红外光谱遥测的大气环境污染监测技术,通过红外光谱遥测测出大气中水汽数据,以防止水汽影响到后续对污染物的计算,通过亮温近似线性叠加特性处理亮温光谱矩阵,通过欧几里得距离得出距离损失函数,得到大气特征数据,考虑大气被微量气体吸收的谱线重叠干扰问题,需反演污染物气体浓度即可完成监测。实验证明所提方法拥有较高的准确性,可实时监测大气变化,以便减少污染对环境的影响。

The pollution of the atmospheric environment will cause regional ecological imbalance and harm human health,so it is necessary to deal with polluted gases.To this end,an atmospheric environmental pollution monitoring technology based on wide-band infrared spectroscopy is proposed.The atmospheric water vapor data is measured through infrared spectroscopy to prevent water vapor from affecting the subsequent calculation of pollutants.The brightness temperature is processed by the approximate linear superposition feature of brightness temperature.The spectral matrix is used to obtain the distance loss function through the Euclidean distance,and the atmospheric characteristic data is obtained.Considering the interference of the spectral lines absorbed by the trace gas in the atmosphere,the pollutant gas concentration needs to be inverted to complete the monitoring.Experiments have proved that the proposed method has high accuracy and can monitor atmospheric changes in real time to reduce the impact of pollution on the environment.
