Early warning method and device of equipment, storage medium and electronic device

The invention provides an equipment early warning method and device, a storage medium and an electronic device, and the method comprises the steps: obtaining the historical input data of first equipment in a first time period before a first moment, wherein the first equipment is high-voltage frequency conversion equipment; determining a measurement point prediction value of a target measurement point of the first device at a first moment according to the historical input data; when it is determined that the first device is abnormal according to the predicted value of the measuring point and the actual value of the measuring point of the target measuring point of the first device at the first moment, carrying out early warning on the first device; besides, under the condition that the firstequipment operates according to the historical input data, the probability that the first equipment breaks down in each time period of one or more time periods after the first time period can be predicted according to the hi
