Nuclear power plant rotating machine equipment vibration data monitoring and early warning method and device and electronic equipment

The invention relates to a nuclear power plant rotating machine equipment vibration data monitoring and early warning method and device and electronic equipment, and the method comprises the steps: carrying out the fault mode analysis of rotating machine equipment, and obtaining a typical fault of the rotating machine equipment; analyzing each typical fault to obtain a vibration signal feature of each typical fault; identifying a vibration characteristic index related to the vibration signal characteristic; determining a vibration sensor at a corresponding position; establishing a feature index calculation model based on the vibration feature index, and performing calculation based on the feature index calculation model to obtain a feature index value; performing index trend monitoring and correlation change monitoring of all vibration characteristic indexes of a single typical fault according to the obtained characteristic index values; and carrying out vibration abnormity early warning on the rotating machi
