Life Detector with respiratory sound FFT analysis

摘要

The subject innovation relates to a life detection system, and more particularly, a parabolic microphone that can detect the breath sound of the organism that are propagated through the air (Parabolic microphone) the analog signals to eyidi converter (A / D Converter detected by: Analog -to-digital through Converter) conversion to a digital signal, and on the basis of the signal component analysis results the intensity of the signal component, and for each frequency by using a digital signal processor of the breath sound to determine oil, absence of the organism It relates to a detector organism by FFT analysis.; According to the present invention, it is possible to detect life on remote can be used to rescue an unconscious person or animal, the exhibition has also be used as a detection device to identify the enemy's existence.
