摘要：
The present invention relates to a system of detecting a sleep disorder based on a micro vibration sensor and a sound sensor which measures micro vibration by a micro vibration sensor installed on a pillow, and measures a sound by a sound sensor to detect sleep apnea or snoring symptoms and record detected symptoms or automatically generate a report. The system of detecting a sleep disorder based on a micro vibration sensor and a sound sensor comprises: a respiration signal detection unit to detect a respiration signal from the micro vibration sensor, and detect a cycle, a phase, and a peak of the respiration signal from the respiration signal； an apnea section estimation unit to estimate a section of a predetermined size around the peak from the respiration signal as an apnea section (hereafter, first apnea section)； a respiration sound extraction unit to receive a sound signal, detect a noise signal, remove the noise signal from the sound signal to extract a respiration sound, detect a sound signal in the first apnea section as the noise signal, and extract a cycle and a phase of the extracted respiration sound from the respiration signal； and a snoring detection unit to compare the cycle and the phase of the respiration sound with the cycle and the phase of the respiration signal to detect a snoring symptom if a level of the respiration sound exceeds a predetermined reference level. A camera is operated if a biosignal such as a heart rate exceeds a predetermined range to photograph and store an image only in a required situation to minimize power consumption of a battery.COPYRIGHT KIPO 2019베개에 설치된 미세진동 센서에 의해 미세진동을 측정하고, 소리감지 센서에서 소리를 측정하여, 수면무호흡 또는 코골이 증상을 검출하고, 검출된 증상을 기록하거나 보고서를 자동으로 작성하는, 미세진동 센서와 소리 센서 기반 수면장애 검출 시스템에 관한 것으로서, 상기 미세진동 신호로부터 호흡신호를 검출하고, 상기 호흡신호로부터 호흡신호의 주기와 위상, 그리고 피크를 검출하는 호흡신호 검출부； 상기 호흡신호로부터 상기 피크를 중심으로 사전에 정해진 크기의 구간을 무호흡 구간(이하 제1 무호흡 구간)으로 추정하는 무호흡구간 추정부； 소리신호를 입력받고 잡음신호를 검출하고 소리신호에서 잡음신호를 제거하여 호흡소리를 추출하되, 상기 제1 무호흡 구간에서의 소리신호를 상기 잡음신호로
