摘要

为实现对大气气溶胶时空变化信息的全天时实时监测,设计了一种B/S架构的Mie散射大气激光雷达数据采集及远程监控系统。利用ARM-Linux平台搭建的嵌入式系统实现了对大气回波信号的实时采集。用Fernald方法即时处理回波信号,实时显示消光系数曲线与时间高度回波强度显示图(THI)。提出的设计基于B/S架构的远程监控系统,具有监控平台无关和监控地点无关等特性,可以更加直观地了解Mie散射大气激光雷达全天时连续探测得到的大气气溶胶时空变化信息。实验表明所设计系统能实时显示消光系数曲线与THI图,具有良好的远程控制能力。

Abstract

In order to realize the real-time monitoring of the spatial and temporal variation of atmospheric aerosol, a data acquisition and remote monitoring system for Mie scattering atmospheric lidar based on B/S architecture is designed. Real time acquisition of atmospheric echo signal is realized by embedded system built with ARM-Linux platform. The echo signal is processed by using Fernald method. The extinction coefficient curve and time-height -indicator (THI) chart are displayed in real time. The proposed design is based on remote monitoring system with B/S architecture. It has characteristics of monitoring platform-independent and location-independent, and the spatial and temporal variation of atmospheric aerosol obtained by Mie scattering lidar all day can be understand more intuitively. Experiments show that the designed system can display extinction coefficient profile and THI figure in real-time, and has good remote control ability.
