Zusammenfassung:The present invention relates to a sensor system capable of separating background noise and a person movement signal from a PIR sensor signal and a signal separation method thereof. The sensor system according to an embodiment of the present invention includes: a passive infrared (PIR) signal collection part to collect a PIR signal from an infrared ray inputted from the outside; a RV calculation part to calculate the number of ripple (Ripple Value : RV) defined by shaking of a signal, from the previously collected PIR signal; and a signal separation part which separates the person movement signal from the collected PIR signal, by comparing the calculated number of the ripples with a previously established threshold as to the number of ripples. 본 발명은 PIR 센서 신호에서 배경잡음과 사람이동신호를 분리할 수 있는 센서시스템 및 그것의 신호 분리방법에 관한 것이다. 본 발명의 일 실시 예에 따른 센서시스템은, 외부로부터 입력되는 적외선으로부터 PIR(Passive Infrared) 신호를 수집하는 PIR 신호수집부; 상기 수집된 PIR 신호로부터, 신호의 흔들림으로 정의되는 리플(Ripple)의 개수(Ripple Value : RV)를 산출하는 RV 산출부; 및 상기 산출된 리플의 개수와 기 설정되어 있는 리플의 개수에 대한 임계값(Threshold)을 비교하여, 상기 수집된 PIR 신호로부터 사람이동신호를 분리하는 신호분리부;를 포함한다.
