s500: through a one-way data pipeline, the first visualization process corresponding to the first visualization display area sends multiple groups of pressure value data changing along with time corresponding to the first expansion degree change to a second visualization process corresponding to the second visualization display area;
s600: responding to the second visualization process to successfully receive a plurality of groups of pressure value data which change along with time and correspond to the first expansion degree change, and sending an initialization instruction by the computer terminal;
s700: a user adopts a vagina digital examination method to carry out an operation experiment, so that the fetus sub-model moves towards the uterine ostium sub-model;
s800: and displaying a second expansion degree change of the uterine ostium submodel caused by the fact that the user performs an operation experiment by using a digital vagina examination method so that the fetal submodel moves towards the uterine ostium submodel on the second visual display area.
7. The method for simulating vaginal digital examination based on human-computer interaction virtual simulation as claimed in claim 6, wherein:
the step S800 further includes:
s801: the method comprises the steps that in the process that the fetal submodel moves towards the uterine ostium submodel, a plurality of groups of pressure values detected by pressure sensors at different positions of the uterine ostium submodel are obtained in real time;
s802: comparing the separation degrees of a plurality of groups of pressure values detected by the pressure sensors at different positions of the uterine ostium submodel in real time with a plurality of groups of pressure value data which are changed along with time and correspond to the first expansion degree change;
s803: judging whether the separation degree exceeds a preset threshold value or not;
if yes, simultaneously displaying a plurality of groups of first pressure value curves which represent the first expansion degree change and change along with time and a plurality of groups of pressure values detected by pressure sensors at different positions of the uterine ostium submodule acquired in real time on the second visual display area, and displaying a separation degree warning signal;
if not, the process returns to step S801.
8. The method for simulating vaginal digital examination based on human-computer interaction virtual simulation as claimed in claim 7, wherein:
the separation degree warning signal comprises a plurality of groups of pressure values detected by pressure sensors at different positions of the uterine ostium submodel acquired in real time, and the predicted future pressure change trends of the different positions of the uterine ostium submodel.
