| 中文摘要: |
| 在国内首次报道了可对30多 种有毒气体连续监测的基于DOAS(differential optical absorption spectra)技术的车载消防应急救援多气体快速遥感仪,仪器采用长光程紫外差分吸收光谱 法痕量气体分析 技术,光发射器和光接收器共用一个卡塞格林望远镜,以减少大气紊动对测量数据的影响； 仪器的反射系 统可以灵活地设置在任意需要区域,分析系统设置在救援车内,在需要长时间监测时,避免 了工作人员近 距离暴露在危险环境中。多气体DOAS仪器特别适合各类气体泄漏事故的消防应急处理。 |
| 英文摘要: |
| In this paper,a vehicle-mounted fire emergency rescue multi-gas monitor based on DOAS (Differential Optical Absorption Spectra) technology is reported,which can continuously monitor more than 30kinds of poisonous gases.A long path ultraviolet differential absorption spectroscopy method for trace gas analysis is used to realize the continuous monitoring the gas components and the concentrations in the air.Optical transmitter and optical receiver share a Cassegrain telescope,in order that the atmospheric turbulence effects on the measurement data can be reduced.Reflection system can be set in any measurement area flexibly,and analytical system is set in the rescue vehicle,which can avoid the rescue worker exposure in dangerous environment at close range when continuous monitoring is required.Multi-gas DOAS system is especially suitable for fire emergency treatment of various gas leakage accidents. |
