Intelligent ammeter error online estimation method based on edge calculation

Abstract

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.

Description

Technical field [0001] The invention belongs to the field of electric energy measurement, and relates to an online error estimation method of a smart meter based on edge calculation. Background technique [0002] With the advent of the electrical 2.0 era, smart meters have replaced traditional meters, greatly reducing the workload of meter reading and manual inspections. At the same time, a large number of smart meters are running on the network, which makes people pay particular attention to the error monitoring of smart meters. For smart meters, most of the errors in the meter are manually detected on site at this stage. Based on the application of smart grid big data, State Grid Corporation proposed the vision of online abnormal state detection and state evaluation of smart meters, hoping to use big data mining technology to estimate the online error of each smart meter online. Summary of the invention [0003] In view of this, the purpose of the present invention is to provi...
