怎样才能做到对雾霾的实时监测?

雾霾天气越来越严重,对大家的生活影响越来越大。但是在对雾霾监测的技术上,却没有足够的成果来实现对雾霾的监测,基于此,虎扑体育app来展示一些雾霾的监测技术。

1.针对水分含量和杂质颗粒浓度大小,利用水分传感器和杂质颗粒浓度传感器来检测雾霾的大小。

2.通过雾霾监测装置,采用发光单元发出蓝色、绿色和红色红外波段光,并对其在雾霾天气中的透射强度进行检测,进而得出各波段光的消光系数,并通过比较蓝色波段光和红色红外波段光对绿色光的相对消光系数比值与预设的雾霾判定阈值范围之间的关系,来准确、客观、自动的判定雾霾天气,提高了雾霾监测的客观性和准确性。

3.PM2.5的检测,主要有三种方式

1)β射线法,这种方法是根据β射线通过颗粒物的能量衰减,计算出颗粒物的浓度。

2)微量震荡天平法,这种方法是根据颗粒物导致滤膜震荡频率的变化,测试出颗粒物的浓度。

3)激光测试法的基本原理是激光为测量光源,激光经颗粒物散射后,对光学传感器输出的脉冲信号进行数字信号处理,从而测试出颗粒物的浓度。
