The invention provides an early warning method for the online operation state of an electric power metering equipment. The method comprises the steps: S1, obtaining the operation monitoring information of the electric power metering equipment in real time, and enabling the operation monitoring information and the preset basic configuration information of the electric power metering equipment to generate a model input quantity in a preset format; s2, inputting the model input quantity into a pre-trained random forest model for operation, counting the running state of each metering equipment output by each decision tree in the random forest model, and voting for the running state of each metering equipment according to a preset voting rule, selecting the metering equipment operation state output with the maximum votes as a prediction result of the online operation state of the electric power metering equipment; and S3, determining whether to carry out early warning on the operation stateof the electric power me
