摘要
介绍了一种基于波长调制光谱技术检测火灾毒性气体组分体积分数的系统,包括系统检测原理分析、硬件以及软件设计,实现了对火灾中常见的三种毒性气体CO(一氧化碳)、CO2(二氧化碳)、HCN(氰化氢)体积分数的实时检测。
Design and implementation of a system based on wavelength modulation spectroscopy and harmonic detection is introduced, including theory, system＇s hardware design and software design. System is capable of measuring the concentrations of carbon monoxide, carbon dioxide and hydrogen cyanide in fire products simultaneously.
