为监测大气黑碳气溶胶,依据黑碳气溶胶的光学特性,研究了基于光衰减法的实时监测系统(黑碳仪),设计了基于光衰减法的黑碳气溶胶浓度测量算法。采用虚拟仪器设计方法,利用Delphi7.0和SQL Server2000开发黑碳仪上位机软件。上位机软件实现了黑碳气溶胶浓度测量算法,并能控制下位机运行情况、存储与静态和动态显示黑碳气溶胶浓度值。研制仪器试验结果表明,黑碳气溶胶测量算法与实现软件达到了设计要求。

To monitor black carbon aerosols in real time, a system （Aethalometer） is studied, and the measurement algorithm of black carbon aerosols concentration based on the method of light attenuation are designed. With the method for designing virtual instrument, the upper computer software is developed by Delphi7.0 and SQL Server2000. The software function is to monitor the black carbon aerosols concentration in real time, to control the lower computer, to store and display the black carbon aerosols concentration. The test results show that the measurement algorithm and the implementing software reach the requirements for this system.
