Research on Data Link Fault Warning Based on Knowledge Graph

Qingqing Su, Ling Zheng

Abstract: In view of the large scale of the data system of State Grid Corporation of China, multiple links and long cycles of data flow between business systems, lack of fault warning mechanism of links, unable to take measures to adjust links in advance, affecting the transmission efficiency of data links, etc., this paper constructs a fault domain ontology of data links, and combines the Jena reasoning mechanism to define inference rules that are in line with the field of data links. The link fault knowledge graph is constructed, and an improved similarity calculation method is designed to realize the fault warning of the data link, and improve the operation and maintenance efficiency of the data link.
