Method for remote monitoring and diagnosing of electric energy metering device enabling fault to be found out in time

Abstract

The invention provides a method for remote monitoring and diagnosing of an electric energy metering device enabling a fault to be found out in time. A monitoring and diagnosing system comprises an electricity information acquiring system, a communication server, a data acquiring and analyzing server, a database server, a service information server, a Web server, a workstation computer and a data bus, wherein data transmission is conducted between the electricity information acquiring system and the data acquiring and analyzing server through the communication server, and the data acquiring and analyzing server, the database server, the service information server, the Web server and the workstation computer are electrically connected through data bus signals. The monitoring and diagnosing method mainly comprises the steps of data acquisition, data calling, analysis, fault warning and electricity compensation quantity information output. By the adoption of the system and method, the fault of the electric energy metering device is found out and dealt with more timely, the electric energy metering monitoring and managing level of a power supply unit is improved, electricity compensation disputes are reduced, manpower and material resources are saved greatly, working efficiency is improved, and loss reduction and efficiency improvement are achieved.
