The invention provides an underwater searching system for fire rescue, and the system comprises fluorescent powder which is pre-coated on a firefighter uniform of a firefighter for underwater rescue; a laser; the collimating lens is arranged in front of the laser, the laser is subjected to beam expansion through the collimating lens, the beam-expanded light irradiates the fluorescent powder, and the fluorescent powder excites fluorescent light; the light filter is used for filtering out the beam-expanded light and enabling the fluorescence to highly penetrate through the light filter; and the photoelectric detector is arranged behind the optical filter, and the photoelectric detector captures and positions the light entering the photoelectric detector. The firefighter's uniform is coated with the fluorescent powder in advance, so that the fluorescent powder can be excited by the laser to emit fluorescent light, the fluorescent light is captured by the photoelectric detector so as to position the firefighter, the laser is subjected to beam expanding through the collimating lens, the irradiation area is enlarged, the light filter can filter the reflected beam expanding light, only the fluorescent light is highly transparent, and the firefighter's uniform can be positioned. And a large amount of background information is filtered.

    本发明提供了一种用于消防救援的水下搜寻系统,包括:荧光粉,荧光粉预涂在下水救援的消防员的消防服上;激光器;准直透镜,准直透镜设置于激光器的前方,且激光经过准直透镜进行扩束,扩束光照射至荧光粉上,荧光粉激发出荧光;滤光片,滤光片过滤掉扩束光,且使荧光高度透过;光电探测器,光电探测器设于滤光片的后方,且光电探测器对进入其内部的光进行捕捉定位。本发明通过预先在消防员的消防服上涂抹荧光粉,使其可以被激光激发出荧光,并被光电探测器捕捉到从而对消防员进行定位,而且通过准直透镜将激光进行扩束,扩大照射面积,滤光片能够过滤掉反射回的扩束光,只对荧光进行高透,过滤掉大量的背景信息。
