Embodiment Construction

[0056] Below in conjunction with specific embodiment the present invention is described in further detail:

[0057] A kind of data quality management system based on the message bus designed by the present invention, such as figure 1 As shown, it includes a data access module 1, a verification rule building module 2, a clustering division module 3, a quality evaluation module 4 and a comprehensive evaluation module 5, wherein the data access module 1 is used to receive through the KAFKA message bus Power monitoring data sent by multiple data sending ends, and stored in categories;

[0058] The verification rule building module 2 is used to construct the data quality rule verification library according to the preset evaluation indicators. The preset evaluation indicators include accuracy, completeness, consistency, usability and real-time performance, and establish corresponding verification according to each indicator. Rules, such as integrity evaluation including field integ...

Abstract

The invention relates to a data quality governance system based on a message bus. The system performs the steps of receiving power monitoring data sent by a plurality of data sending ends through themessage bus and stored in a classified mode; determining a power monitoring data quality evaluation index, and constructing a data quality rule verification library; clustering the power monitoring data by adopting a k-means clustering method optimized on the basis of a grey wolf longhorn beard search algorithm, and dividing the power monitoring data into a plurality of data subsets; for each datasubset, carrying out accuracy evaluation through an LOF abnormal value detection algorithm, and carrying out integrity, consistency, availability and real-time evaluation through data quality rule verification; and calculating the weight of each evaluation index through an improved analytic hierarchy process, and calculating a comprehensive evaluation result of the power monitoring data quality.According to the system, the multi-dimensional quality evaluation of the power monitoring data is realized, and the reliability of the quality management of the power monitoring data is improved.

Description

[0001] technology neighborhood [0002] The invention relates to the technical field of automation information systems, in particular to a data quality management system and method based on a message bus. Background technique [0003] With the increasing number of automated information systems, the scale and capacity of power systems are increasing, and the amount of information is increasing. With the vigorous promotion of monitoring terminals, the characteristics of monitoring objects are different, and the early warning function of monitoring data correlation calculation is gradually highlighted. With the rapid growth of data, the data quality of different data sources is uneven, and data quality has different concepts and standards. Data quality generally includes quantitative descriptions such as data accuracy, completeness, timeliness, and consistency. [0004] For power systems in the era of big data, the amount of data that needs to be stored and processed is large, a...
