| 摘 要： | 提出用CO作为早期火灾探测的观察对象,利用红外光谱法进行气体探测,并在此基础上建立了基于FTIR的试验系统.通过该方法成功获得CO的浓度值.并用时间序列分析方法建立二阶自回归模型,提取出特征参数进行分析,能在较短时间内将真假火灾区分开来.

| Abstract: | It was proposed that CO could be chosed as a target gas to detect early fires.A specific experiment system was set up based on FTIR technology.By using time series analysis,an auto-regressive models for the concentration of CO can be built.Finally,characteristic parameters of models can distinguish the real fire source from nuisance sources in short times. |
