Embodiment Construction
[0029] Such as figure 1 As shown, the present invention discloses an intelligent detection unit 308 for extracting PACE waves, including a digital filtering unit, an edge enhancement and sharpening unit 402, a PACE wave shape similarity extraction unit 403, and a PACE wave characteristic parameter extraction unit 404. The input end of the filter unit is used to receive the PACE wave digital signal, the digital filter unit is used to filter the PACE wave digital signal out of high and low frequency noise, and the output end of the digital filter unit is connected to the input end of the edge enhancement and sharpening unit 402 The edge enhancement and sharpening unit 402 is used to sharpen the rising / falling edge of the PACE wave digital signal after filtering, suppress low frequency components, and make the edge of the signal more steep, and the edge enhancement and sharpening unit 402 output terminal It is connected with the input end of the PACE wave form similarity extracti...
