摘要：
A method of identifying whether a subject drinks alcohol by physiological signals.It includes a physiological signal measurement step.Measure the electrogram signal of the subject's heart.A blood flow signal and a pulse signal；1. Noise suppression step；Suppress the noise interference caused by the measurement operation in the measurement physiological signal step；A feature extraction step,Multiple time domain features and multiple frequency domain features are extracted from the R-R interval of the ECG signal.And Hilbert transform the blood flow signal and pulse signal, and then extract the average peak characteristics；And one identification step,Using a classifier, the ECG signal isThe blood flow signal and pulse signal are judged to be in a drinking state or a non drinking state.Thus, the subject was judged to have or not to have alcohol.一種藉由生理訊號識別受測者是否有飲酒的方法，包含一測量生理訊號步驟，測量該受測者之一心電圖訊號、一血流量訊號及一脈搏訊號；一雜訊抑制步驟，抑制在該測量生理訊號步驟中因測量操作而產生的雜訊干擾；一特徵擷取步驟，自該心電圖訊號的R-R區間擷取多個時間域特徵及多個頻率域特徵，及對該血流量訊號及脈搏訊號進行希爾伯特轉換並繼而擷取平均峰值特徵；及一識別步驟，使用一分類器依據上述特徵將該心電圖訊號、血流量訊號及脈搏訊號判定為屬於一有飲酒狀態或一無飲酒狀態，從而判定該受測者有飲酒或無飲酒。
