專利摘要(中)
本發明提出一種基於心血管生理訊號的壓力檢測方法與使用此方法的系統。所述方法包括：基於心血管生理訊號得到多個訊號片段，這些訊號片段在擴張的迪基-福勒（Augmented Dickey-Fuller，ADF）檢定下為穩定；分別計算這些訊號片段的多個趨勢；基於這些趨勢，得到心血管生理訊號對應的去趨勢訊號；基於去趨勢訊號，提取多個第一心率變異度（Heart Rate Variation，HRV）特徵；以及基於這些第一HRV特徵，得到心血管生理訊號對應的壓力檢測結果。

專利摘要(英)
A method for pressure detection based on cardiovascular physiological signals and a system using the method are provided. The method includes: obtaining multiple signal segments based on a cardiovascular physiological signal, where the signal segments are stable under an augmented Dickey-Fuller (ADF) test; calculating multiple trends for the signal segments; obtaining a detrended signal corresponding to the cardiovascular physiological signal based on the trends; extracting multiple first heart rate variability (HRV) features based on the detrended signal; and obtaining a stress detection result corresponding to the cardiovascular physiological signal based on the first HRV features.
