| 摘 要： | 将TDLAS(Tunable Diode Laser Absorption Spectroscopy)技术应用于极早期火灾气体产物的检测.对于火灾早期特征气体CO和CO2气体探测,选择中心波长为1582nm和1607nm的近红外吸收谱线,设计了一个基于TDLAS的火灾气体探测系统.对于CO和CO2气体,最低检测灵敏度分别达到2.3×10-6和22×10-6体积比浓度.该系统信号响应线性度高,长期运行稳定.

| Abstract: | Tunable Diode Laser Absorption Spectroscopy(TDLAS) was used to detect early fire gas.1582nm of CO absorption line and 1607nm of CO2 absorption line were chosen for early fire gas carbon monoxide and carbon dioxide.A fire gas detection system with tunable diode laser absorption spectroscopy was established.The lowest detection limit for carbon monoxide and carbon dioxide were 2.3×10-6 and 22×10-6.The system signal response linearity was well and ran steadily for long time. |
