Embodiment Construction
[0017] The present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be emphasized that the following descriptions are only exemplary and not intended to limit the scope of the present invention and its application.
[0018] This embodiment provides a system for extracting blood pressure data from a pulse wave signal, including: an acquisition unit that acquires the pulse wave and corresponding blood pressure data and performs preprocessing; a separation unit that performs complete waveform detection and separation of the preprocessed pulse wave; The conversion part performs frequency domain transformation on each complete pulse waveform and extracts the frequency domain features; the training part takes the frequency domain features as input and the corresponding blood pressure value as output, and combines the neural network for predictive model training to obtain blood pressu...
