Intelligent diagnosis system based on metering device failures

Abstract

The invention relates to an intelligent diagnosis system based on metering device failures. The intelligent diagnosis system comprises a data collecting and monitoring module, a meta event information generating module and a failure diagnosing and decision making module, wherein the data collecting and monitoring module is used for collecting and uploading related data according to collection frequency and transmission modes, the meta event information generating module is connected with the data collecting and monitoring module and used for comprehensively analyzing and preprocessing the related data collected through the data collecting and monitoring module, matching the collected related data according to the archival information of a user and generating meta event information through a meta event diagnosing model; the failure diagnosing and decision making module is connected with the meta event information generating module and used for carrying out relevance matching according to the meta event information provided by the meta event information generating module to achieve intelligent diagnosing of the metering device failures. Compared with the prior art, the intelligent diagnosis system has the advantages that information is effectively integrated, redundant information is removed, the diagnosing efficiency is improved, and the diagnosing accuracy is high.

Description

technical field [0001] The invention relates to the field of electric power systems, in particular to an intelligent diagnosis system based on faults of metering devices. Background technique [0002] According to the construction goal of the State Grid Corporation of China on the electricity consumption information collection system, all units of the company have carried out the construction of the collection system. As of the end of 2015, Shanghai Branch has collected and covered 9.92 million users, basically achieving full coverage. The success rate of collection has remained above 98.8%. The system is running stably and can support the development of various in-depth applications. The acquisition system has played significant economic benefits in reducing losses and increasing income, saving management and labor costs; it has achieved remarkable management results in supporting the construction of the "big marketing" system, implementing tiered electricity prices for res...

Problems solved by technology

The diagnosis system of existing metering devices is difficult to manage a large number of running electric energy metering devices. At the same time, because the events, data and other information generated by electric energy meters and collection terminals are only aimed at their own conditions and lack effective correlation, the collection system collects a large number of Due to various uncertain reasons, the information has characteristics such as incompleteness and inconsistency, making it impossible to make accurate judgments and interpretations of events only relying on them
