Equipment fault early warning method and device, storage medium and computer equipment

The invention provides an equipment fault early warning method and device, a storage medium and computer equipment, and the method comprises the steps: obtaining a plurality of abnormal state recordsof the equipment, wherein each abnormal state record comprises an abnormal state parameter of the equipment; establishing a Bayesian network model based on the corresponding relationship between the abnormal state parameters and the faults in the plurality of abnormal state records, wherein the Bayesian network model is used for determining the fault probability of corresponding faults under the condition that abnormal state parameters occur, the abnormal state parameters are root nodes of the Bayesian network model, and the faults are child nodes of the Bayesian network model; acquiring abnormal state parameters of the equipment in real time, and determining a fault probability corresponding to the abnormal state parameters based on a Bayesian network model; and when the fault probabilitymeets an early warning th
