基于LabVIEW的大气气溶胶实时监测系统设计

近年来随着人们对大气环境质量的重视程度日益提高，大气气溶胶浓度的定量分析方法也越来越受到关注。该大气气溶胶实时监测系统基于Mie弹性散射分析技术，利用LabVIEW数据流图形化编程方法完成数据实时处理、动态显示以及历史数据保存等功能。系统可以通过实时获取单个气溶胶粒子在激光照射下后向散射光的强度来分析采集样本中各粒度气溶胶粒子浓度，并以此来评估当前环境的气溶胶质量状况。此系统具有操作简单、界面友好、数据翔实的优点，可广泛应用于大气气溶胶分析领域。

Design of atmospheric aerosol real time monitoring system based on LabVIEW

In recent years, with great importance increasingly attached to atmospheric environmental quality, methods of quantitative analysis for the concentration of atmospheric aerosol was receiving more and more attention. The atmospheric aerosol real time monitoring system was based on Mie scattering analytical technique, taking the advantage of LabVIEW data stream graphical programming to realize the functions of real time process, dynamic display and historical data saved. This system analyzed the concentration of sampled various size aerosol particle by real time getting the back scattering light intensity of every aerosol particle, which can reflect the air quality of current environment. This system had advantages of easy operation, friendly interface and abundant information, which can be widely used for atmospheric aerosol analysis area.
