摘要/Abstract

摘要： 针对大火浓烟环境下能见度极低而造成消防员搜救、施救困难的现状，提出了基于激光距离选通成像的火场透火透烟侦察技术，开展了木垛火、正庚烷火透火实体试验和密闭空间透烟试验，可实现纵深1.5 m火焰的穿透、浓烟环境下能见度提升3倍，解决了目前由于表/界面反射、背向散射严重而无法穿透火焰浓烟的难题。基于试验结果，探讨了距离选通成像在消防可视化侦察及搜救中的应用前景，进一步明确了该研究领域未来的发展方向。基于激光距离选通成像技术研发的火场侦察搜救装备，可为消防救援人员开展建筑受限空间火灾的内攻救援及撤离提供“透视眼”，有望切实提高大火浓烟以及夜间环境下初战控火、快速内攻及人员搜救能力。

Abstract: In view of the difficulty of firefighters' search and rescue due to the extremely low visibility in the dense smoke environment of fires, we proposed a fire penetration and smoke detection technology based on laser range gate imaging, and carried out physical experiments on imaging through wood pallets, n-heptane fires and smoke in confined spaces, which can image through 1.5 m longitudinal flame and improve the visibility in dense smoke environment by 3 times, solving the current problem that fires and smoke cannot be penetrated due to surface/interface reflection and serious backward scattering. Based on the experimental results, the application prospect of laser range gate imaging in firefighting visualization reconnaissance and rescue is discussed, and the future development direction of this research field is further clarified. The future development of fire reconnaissance and rescue equipment based on laser range gate imaging technology provides "perspective eyes" for fire rescue personnel, which is expected to effectively improve the fire control, rapid internal attack and personnel rescue capabilities in the initial battle and night environment.
