技術說明

本專利一種藉由生理訊號識別受測者是否有飲酒的方法，本專利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。本專利的方法具備一雜訊抑制步驟，可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。同時，本專利的方法具備一特徵擷取步驟，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數學轉換並繼而擷取平均峰值特徵。另外，本專利的方法具有一識別步驟，可使用一個特殊設計的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。 This patented method is to identify whether subjects are drinking through physiological signals. In the method of the patent, it has a noise suppression step, which can suppress noise interference in the measurement of physiological signals generated by the measuring step. Meanwhile, this patented method has a signal's feature extraction method for signals extracted from drinkers. The extracted features for identifying drinking include those features from the R-R interval of ECG in time domain and frequency domain. At the same time, the extracted features also include the features of peak averages from the signals of blood flow and heart beats after a mathematical transformation. In addition, the patented method possess a special classification algorithm, which can identify if a person is in drinking by classifying the acquired signal's features mentioned above.
