Aircraft fire detection method based on CO2 concentration monitoring

  • 摘要: 目前飞机普遍采用感温、感烟火警探测方法,其存在误报率高的缺陷.分析了发生火灾时气态燃烧产物的生成规律,提出了以CO2气体为火警探测参量,通过准确监测环境中CO2气体浓度的变化,进行飞机火警探测的方法;根据飞机飞行所处环境条件的特殊性,研究了基于非色散红外(NDIR)吸收原理的CO2气体浓度监测的飞机火警探测方法应用于飞机上所面临的温度补偿难题;根据飞机火警探测器测量电压与环境温度、参比电压之间的关系,采用偏最小二乘(PLS)法建立飞机火警探测器温度补偿模型;根据飞机火警探测器测量电压与CO2气体浓度之间的关系,采用PLS法建立CO2气体浓度计算模型;研究了基于CO2气体浓度监测的报警算法,为飞机火警探测提供了一种新的方法.
