Zusammenfassung:	The present invention relates to a method and system for detecting an abnormal sign in a construction site. The system for detecting an abnormal sign in a construction site according to the present invention includes: an acoustic analyzer for receiving an acoustic signal of the construction site and transmitting the acoustic signal; and an acoustic analysis server for receiving the acoustic signal of the construction site and detecting an abnormal sign by comparing the received acoustic signal with normal sound or accident sound data. The acoustic analysis server comprises a learning algorithm for a normal sound and an abnormal signal by extracting the characteristics of the acoustic signal and classifying the characteristics by category. 본 발명은 건설현장 이상징후 감지 방법 및 시스템에 관한 것으로, 본 발명에 따른 건설현장 이상징후 감지 시스템은 건설 현장의 음향 신호를 입력 받고, 상기 음향 신호를 전송하는 음향 분석기; 및 상기 건설 현장의 음향 신호를 수신하고, 상기 수신한 음향 신호를 정상음 또는 사고음 데이터에 비교하여 이상 징후를 감지하는 음향분석 서버;를 포함하고, 상기 음향분석 서버는, 상기 음향 신호의 특징을 추출하여 카테고리 별로 구분하여 정상음과 이상 신호에 대한 학습 알고리즘을 구성한다.
