Abstract
The present invention relates to the field of biomedical signal processing, specifically, a device and method of implementation for enhancing the accuracy of fetal heart rate acceleration data recognition. The present invention comprises: collecting fetal heart rate data in a pre-configured period so as to obtain a fetal heart rate data sequence, H(n); performing baseline identification on the fetal heart rate sequence, H(n), to obtain a fetal heart rate baseline data sequence, B(n); pre-processing the fetal heart rate data sequence, H(n), to obtain a pre-processed fetal heart rate data sequence, C(n); performing acceleration recognition on the pre-processed fetal heart rate data sequence, C(n), according to pre-configured acceleration determination criteria and the fetal heart rate baseline data sequence, B(n), to obtain acceleration data segments; calculating an acceleration attribute value for each of the acceleration data segments, and outputting each acceleration data segment and the acceleration attribute value calculation result thereof. The technical solution provided by the present invention effectively distinguishes the variations between the accelerations and the baselin…
