The invention relates to an intelligent ammeter error online estimation method based on edge calculation. The comprises the following steps of step S1, acquiring the number information and the electric quantity information of an intelligent electric energy meter by the intelligent ammeter through a mobile terminal, establishing an ammeter data set, and transmitting the ammeter data set to an intelligent air switch for storage; step S2, enabling the intelligent air switch to acquire real-time data of each intelligent ammeter through the mobile terminal and calculating an ammeter error coefficient; step S3, enabling the intelligent air switch to store the calculated error coefficients of all the ammeters in a memory chip; and step S4, calling the data stored in the intelligent air switch byan intelligent ammeter error on-line analysis system, and storing the data in a database; and step S5, analyzing the database in real time by an intelligent ammeter error analysis terminal, and givingan alarm to remind the worker to check at the field if discovering that the continuous K-times of error analysis results of the same ammeter are displayed as tolerance. Through the method disclosed by the invention, the accuracy of the error prediction is greatly improved, an operation of calculating the electric energy error from the terminal is realized, and the precise prediction is realized.
