Abstract

The invention discloses a method, system, medium and equipment for identifying and marking fetal movement signals. The method comprises the steps of: acquiring fetal heart rate acceleration curves, uterine contraction curves and fetal activity diagrams; Baseline calculation and fetal heart rate acceleration identification to obtain fetal heart rate acceleration information; obtain the first fetal activity information by smoothing the signal of the uterine contraction curve and search for fetal movement information; calculate the baseline of the fetal activity graph curve and dynamic threshold to extract fetal movement information and obtain second fetal movement information; calculate the total score of fetal heart rate acceleration index score, uterine contraction fetal movement information index score and fetal movement index score of fetal activity map, and mark fetal movement events. The present invention comprehensively judges the weights of the three signal sources of fetal heart rate acceleration, uterine contraction and fetal movement information and fetal movement information and realizes fetal movement signal marking, making the judgment source of fetal movement signal more comprehensive and increasing the accuracy of fetal movement marking .

Description

technical field [0001] The invention relates to the field of information technology, in particular to a method, system, medium and device for identifying and marking fetal movement signals that can be used in electronic fetal monitoring software products. Background technique [0002] At present, the most commonly used fetal movement recognition algorithm based on Doppler ultrasound signal fetal activity map (Actogram) is the threshold judgment (including static threshold and dynamic threshold) method, and usually only refers to several calculated parameters, according to the agreed rules for identification 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 for detecting fetal movement using the Otsu method, but this method uses static The threshold detection method cannot well adapt to the dynamic changes of fetal mo...
