Abstract

The invention discloses a fetal movement signal recognizing and marking method, a system, a medium and equipment. The fetal movement signal recognizing and marking method comprises the following steps: acquiring fetal heart rate acceleration curve, uterine contraction curve and fetal movement chart; performing fetal heart rate baseline calculation and fetal heart rate acceleration recognition on the fetal heart rate acceleration curve so as to acquire fetal heart rate acceleration information; performing smoothing-processing on signals of the uterine contraction curve so as to obtain difference signals, and searching for fetal movement information so as to obtain first fetal movement information; carrying out fetal movement chart curve baseline calculation and dynamic threshold extraction of fetal movement information so as to acquire second fetal movement information; and then, calculating total score of fetal heart rate acceleration index score, uterine-contraction fetal movement information index score and fetal-movement-chart fetal movement index score, and marking a fetal movement event. The invention integrates weights of three signal sources, namely the fetal heart rate acceleration, the uterine-contraction fetal movement information and the fetal-movement-chart fetal movement information so as to comprehensively judge and realize fetal movement signal marking, thereby making judgment sources of fetal movement signals more comprehensive; and thus, accuracy of fetal movement marking is improved.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a method, system, medium and equipment for identifying and marking fetal movement signals that can be used in electronic fetal monitoring software products. Background technique [0002] At present, the fetal movement recognition algorithm based on Doppler ultrasound signal fetal activity map (Actogram) is more commonly used threshold judgment (including static threshold and dynamic threshold) method, and usually only refers to several calculated parameters, according to the agreed rules for recognition and judgment . For example, "Fetal heart rate baseline estimation with analysis offetal movement signal" published by Lu et al. in the journal Bio-Medical Materials and Engineering in 2014 introduced a method using the Otsu method to detect fetal movement, but this method uses a static The threshold detection method cannot adapt well to the dynamic changes of fetal m...
