基于太阳光源的车载被动DOAS系统的研制

Design for the auto onboard passive differential optical absorption spectroscopy system using the sun as light source

研制基于太阳光源的车载被动差分光学吸收光谱(DOAS)系统在大气质量监测领域具有重要的意义。在分析该系统功能需求的基础上,提出该系统的总体设计思想和技术实现途径。系统通过在汽车上安装GPS模块和小型化的固定式被动DOAS系统完成硬件设计,采用C++ Builder 6.0语言编写具有自主知识产权的应用软件。外场实验表明,该系统操作方便、性能可靠,具有较好的应用推广前景。

Designing an auto onboard passive DOAS （differential optical absorption spectroscopy） system using the sun as light source is of great importance to measure the atmospheric quality. The thesis, therefore, proposes not only the hardware and the software designs of the system based on the analyses of its required function, but also its realizing methods. The hardware component is fulfilled by installing in the automobile a GPS receiver and a mini fixed DOAS system. An independent development with intellectual property right for software system is brought forward by C＋＋ Builder 6.0 language. Outfield test proves that the system is characterized by easy operation, reliable function and promising application foreground.
