High-efficiency remote monitoring and diagnosis method for electric energy metering device

Abstract

The invention provides a higher-efficiency remote monitoring and diagnosis method of an electric energy metering device. A monitoring and diagnosis system used comprises a power utilization information acquisition system, a communication server, a data collection and analysis server, a database server, a service information server, a Web server, a workstation computer and a data bus, wherein the power utilization information acquisition system transmits data via the communication server and the data collection and analysis server; and the data collection and analysis server, the database server, the service information server, the Web server and the workstation computer are in signal electric connection via the data bus. The monitoring and diagnosis method mainly comprises the steps of data acquisition, data call, analysis and processing, fault alarm and to-be-supplemented electricity information output. The method improves timeliness of finding and treating faults of the electric energy metering device, and is advantageous in raising an electric energy metering monitoring and management level of a power supply organization, reducing electricity supplement disputes, saving manpower and material resources greatly, improving working efficiency, reducing loss and improving an effect.
