摘　　要：针对当前民用飞机货舱普遍采用的光电式烟雾探测报警器虚警频发问题,分析了火警探测器的参数设置不当及在复杂航空运输环境下烟雾颗粒性状发生变化,导致难以区分火灾烟雾颗粒与干扰颗粒而产生误报的原因。总结了国内外民机火灾探测技术研究现状并指出存在的问题,尤其缺乏对于飞机货舱变压环境下的火灾烟气探测机理的研究。在此基础上,明确了基于无线传感网络的火灾探测技术、多传感器探测技术、基于TDLAS的多技术协同探测技术等可靠性更高的货舱火灾探测技术将是今后研究重点,从而有效提高货舱火情判断的正确率,解决货舱火灾虚警问题。Aiming at the frequent false alarm of photoelectric smoke detection which is widely used in civil aircraft cargo compartment, different reasons for frequent false alarm are analyzed in detail, such as fire detector parameter settings and the complex environment in air transport leading to the difficult distinguishment between fire smoke particles and particles, etc. This paper summarizes the current situation of fire detection technology for civil aircraft home and abroad and points out the existing problems, especially there is a lack of researches on the mechanism of smoke detection in aircraft cargo compartment under dynamic pressure environment. On this basis, the more reliable cargo compartment fire detection technology, such as fire detection technology based on wireless sensor network(WSN), multi-sensor detection technology, multi-technology cooperative detection technology based on TDLAS, will be the focus of future research, which can effectively improve the accuracy of cargo fire judgment and solve the problem of cargo compartment fire false alarm.
