Fetal heart rate monitoring system and method

A fetal heart monitoring system comprises an acquisition part used for acquiring fetal heart signals of a fetus; the processing part is used for processing the fetal heart signal and outputting a detection result; the acquisition part is configured to be a plurality of fetal heart probes covering a to-be-detected area in an array mode, and the processing part divides at least one signal reaction area based on the signal intensity fed back by the fetal heart probes and determines a sampling fetal heart probe and a spare fetal heart probe based on a preset rule. The acquisition part is used for carrying out weight calculation associated with signal intensity on an acquisition signal of the sampling fetal heart probe to obtain at least one fetal heart detection result; and the spare fetal heart probe and the sampling fetal heart probe are configured to switch working states under the condition that the fetal heart signals acquired by the processing part do not conform to a preset rule so as to continuously acqui
