基于手持设备的烟尘浓度监测软件设计

摘要

烟尘浓度是大气环境质量监测的一项重要指标,本文介绍了一种检测烟尘浓度的常用方法 -光散射法,设计了一种基于ARM嵌入式设备的烟尘浓度在线监测系统,完全可以通过搭载Android系统的智能手机来实时监测烟尘浓度,相比传统的人工监测,它具有更大的移动性、便捷性。本文主要讨论了监测系统的软件部分设计,首先利用无线网络接收传感器采集到的数据,然后进行分析计算并在手持设备上存储和绘制动态曲线,这种方法比起传统的有线连接的监测设备更加灵活。%Flue and Dust emission concentration is an important indicator of the atmospheric environmental quality monitor.This paper introduces a method that is used to measure concentration of flue and Dust emission — the light scattering method,and designs a on-line monitoring system of smoke concentration based on ARM embedded equipment.It can monitor the concentration of flue and dust emission in the mobile telephone based on Android platform,it brings us a great convenience compared with the traditional manual monitoring.It mainly discusses software design of the system,firstly we need to receive the data by the wireless network from instrument,then to analyze and store data and draw a dynamic curve on the PDA.It is very flexible compared with traditional wire connection.
