Abstract

The invention discloses a mass unstructured distribution network data integration method based on knowledge mapping technology. The method includes that a data collection unit collects unstructured distribution network data of each informatization system, and quality analysis and data cleaning processing are performed on the unstructured distribution network data of each informatization system; according to the processed unstructured distribution network data of each informatization system, data local index based on local knowledge mapping is constructed; the data local index based on the local knowledge mapping is sent to a data management center through a big data connector; the data management center constructs data global index based on global knowledge mapping. Collection, quality analysis and data cleaning of distributed multi-source heterogeneous data are advanced to each informatization system, so that data fusion calculation quantity, storage pressure and data scheduling burden of the data management center are lowered; the data global index based on the global knowledge mapping is utilized to integrate data sources, so that convenience is brought to data inquiry and extraction, and workload of the data management center is reduced.

Description

technical field [0001] The invention relates to the technical field of data fusion and integration, in particular to a massive unstructured distribution network data integration method based on knowledge map technology. Background technique [0002] The power grid includes information systems such as marketing systems, production systems, distribution data collection and monitoring systems, and energy meters. Massive data, combined with business system data such as marketing system and production system, and effectively identify and filter the data, finally output relevant data that is beneficial to power operation and improves customer service quality and service level. [0003] The distribution network data collected from various information systems can be divided into two types, one is structured data, such as data or symbol data, and the other is unstructured data, such as user voice, image, text, etc. The existing unstructured distribution network data integration meth...
