The invention discloses an electric energy meter fault number prediction method, and relates to a fault prediction method. In the prior art, an electric energy meter demand or alternating method is adopted, and the number of faults occurring in batches of electric energy meters every month is not predicted. The method comprises the following steps of: solving a moving average number sequence of asequence for imported data, establishing an ARIMA model for the moving average sequence, and predicting the future of the moving average sequence by using the model; and finally, restoring the seasonality of the predicted data, and finally obtaining a prediction result. According to the method, the time sequence decomposition model, the exponential smoothing model and the time sequence ARIMA modelare combined for use, and advantages and disadvantages can be made up; the accuracy and economy of predicting the fault number of the electric energy meter are improved, the quality risk and propertyloss caused by overdue and overstock of the electric energy meter are avoided, the cost input returned by the overdue meter is reduced, and the overstock of the inventory electric energy meter is avoided.
