Embodiment Construction
[0059] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0060] Such as figure 1 As shown, in an embodiment of the method and device for obtaining the envelope of the fetal heart sound signal of the present invention, the method for obtaining the envelope of the fetal heart sound signal includes the following steps:
[0061] Step S11 collects the fetal heart sound signal and performs preprocessing: in this step, collects the fetal heart sound signal and performs preprocessing on it, that is, uses a sensor to pick up the fetal heart sound signal of the fetus in the abdomen of the pregnant woman, and then uses the obtained fetal heart sound signal After the sound signal is processed by hardware filtering, amplification, etc., it is input to the acquisition device for data acquisition; then, preprocessing is performed on the acquired fetal heart sound signal, such as band-pass filtering.
[0062] Step S12 obtain...
