Problems solved by technology
[0004] This application provides a method and device for grid ledger data fusion based on keyword search, which is used to solve the "data island" phenomenon caused by abnormal data naming in the prior art. The existing processing method can only manually analyze the abnormal data. Checking, comparing and correcting one by one is time-consuming and labor-intensive, which leads to the existing technical problem of inefficient processing of "data islands" caused by abnormal data naming

Embodiment Construction
[0034] The embodiment of the present application provides a method and device for grid ledger data fusion based on keyword search, which is used to solve the "data island" phenomenon caused by abnormal data naming in the prior art. The existing processing method can only be manually processed. It is time-consuming and labor-intensive to check, compare and correct abnormal data one by one, which leads to the low efficiency of the existing "data island" processing method caused by abnormal data naming.
[0035] In order to make the purpose, features and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the following The described embodiments are only some of the embodiments of the present application, but not all of them. Based on the embodiments in this...

This application discloses a method and device for grid ledger data fusion based on keyword search, wherein the method provided by this application combines accurate keyword matching and initial letter fuzzy matching, and firstly extracts keywords to eliminate data naming information For identification words that have nothing to do with regional information and equipment information, the initial data matching and association is carried out through keyword comparison, and then through the initial letter matching method, the second fuzzy matching is performed on the data that the initial data matching fails to reduce. Input errors lead to data matching failures, resulting in the probability of new "data islands", and also solve the phenomenon of "data islands" caused by abnormal data naming. The existing processing methods can only manually check and compare the abnormal data one by one. Correction, time-consuming and labor-intensive, resulting in the existing technical problem of low processing efficiency of "data islands" caused by abnormal data naming.
Description
technical field [0001] The present application relates to the field of data fusion, in particular to a method and device for data fusion based on keyword search. Background technique [0002] With the maturity of big data technology, the power grid operation and maintenance departments in various places have gradually established a power quality monitoring system based on grid big data by establishing standardized databases and data fusion. However, each database system is managed by different management teams, and these data are independent and heterogeneous data before fusion, due to personal preferences of managers or human errors when entering information, resulting in Even the same data object may have different names in different database systems, which ultimately makes it difficult for these abnormally named data objects to be merged with the same data object during data fusion, and difficult to merge with other legal data objects. Correlation, forming a new "data is...
