Early warning method and system for sudden instability change of rock mass and electronic equipment

The invention discloses a rock mass instability abrupt change early warning method and system and electronic equipment, and relates to the technical field of geotechnical engineering.The method comprises the steps that acoustic emission monitoring data of a target rock mass at the current moment are obtained; the target rock mass is a rock mass to be subjected to rock mass instability mutation early warning; determining the instability condition of the target rock mass at each to-be-predicted moment based on the acoustic emission monitoring data at the current moment, the acoustic emission grey prediction model and the rock mass instability grey-folding mutation model; the to-be-predicted moments are moments after the current moment, and the instability condition is a stable state, a critical state or an unstable state; the acoustic emission grey prediction model and the rock mass instability grey-folding mutation model are determined based on acoustic emission monitoring data at each historical moment in the
