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...

The invention discloses a power grid standing book data fusion method and device based on keyword search. According to the method provided by the invention, a mode of combining keyword accurate matching and initial letter fuzzy matching is adopted; first, removing keyword extraction, identification words irrelevant to the regional information and the equipment information in the data naming information; performing primary data matching association through keyword comparison; then, adopting the initial letter matching mode; carrying out secondary fuzzy matching on the data which are not successfully matched with the primary data; reducing data matching failure caused by manual input errors; according to the method, the probability of generating a new data island is generated, the data island phenomenon caused by data naming abnormity is also solved, and the technical problem that an existing processing method is low in processing efficiency of an existing data island caused by data naming abnormity due to the fact that abnormal data can only be manually checked, compared and corrected one by one, and time and labor are wasted is solved.
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...
