An intelligent electric energy metering device online calibration system

Abstract

The invention relates to an intelligent on-line checking system of an electric energy metering device. The system is composed of a base station side module, network side modules, and a headquarter side module. The base station side module includes a plurality of base station front-end checking devices; all base station front-end checking devices store online checking data into information storage units in the base station side module, the online checking data of all base stations are transmitted to data centers in the network side modules; and then trans-regional data in all network side modules are transmitted to a data centralized display cloud platform in the headquarter side module for centralized displaying; and the data centralized display cloud platform carries out remote invoking and on-line remote controlling on on-line checking states of all base stations. The on-line checking system has characteristics of high information level and diversified functions and is connected with a mobile phone APP; and the mobile phone connected to the internet receives measurement data of online checking by the APP. Therefore, real-time remote controlling of online checking of the electric energy metering device is realized; and alarming and repairing are carried out on the out-of-tolerance electric energy metering device timely.
