The invention relates to the technical field of
medical instruments, in particular to a
fetal heart rate acceleration recognition method and
system. The method comprises the following steps: acquiring a Doppler echo original
signal of a
fetal heart, comparing the Doppler echo original
signal with a preset threshold after
simulation conditioning, and outputting an effective
signal starting point and an initial
data stream; on the basis of the effective signal starting point and the initial
data stream, collecting is stopped after preset-length data is accumulated, audio is played after filtering and amplifying
processing, if the
continuous signal duration exceeds a set threshold value, current
data segment retention is stopped, and the processed audio and the current
data segment are output; in combination with the effective trigger identifier and the instantaneous
fetal heart rate, the steps are executed circularly, interference signals are eliminated, and a real-time
fetal heart rate monitoring result and an abnormal prompt are output; by means of accurate screening, real-
time processing and dynamic threshold value
adaptation of whole-process signals,
fetal heart monitoring with high anti-interference capacity and high real-time performance is achieved, the real-time
fetal heart rate and an abnormal prompt can be accurately output, and the
fetal heart monitoring quality during
pregnancy is effectively improved.
