Device and method for analyzing and inquiring alarm information based on time sequence similarity

Abstract

The invention discloses a device and a method for analyzing and inquiring alarm information based on time sequence similarity, and belongs to the technical field of alarm information analysis and query. In the prior art, alarm information association mining is essentially based on alarm information co-occurrence historical data. The alarm information co-occurrence data in the real data is not much, the coverage ratio of the alarm information which is really associated is very small, and the error rate of subsequent alarm information positioning of operation and maintenance personnel is very large due to the result of alarm information query from the surface. The system comprises an alarm information source, an alarm information time slicing module, an index time sequence data module, an alarm information association expansion module, an alarm information association mining module and a root cause analysis query service module. The invention also provides a corresponding alarm information analysis and query method. The method is used for realizing alarm information analysis and query after the alarm information is expanded.

Description

technical field [0001] A device and method for analyzing and querying alarm information based on time series similarity are used to realize alarm information analysis and query after expanding alarm information, and belong to the technical field of alarm information analysis and query. Background technique [0002] When an operation and maintenance engineer faces a large number of complex types of fault alarm information from different monitoring systems every day, the operation and maintenance engineer needs to have a certain understanding of the system, application, and business, and complete the alarm based on personal experience Information location problem. [0003] With the gradual improvement of my country's enterprise information construction, more and more monitoring and alarm information, application and system information are stored and managed. By analyzing these system information and application information, the operation and maintenance work (such as: positio...

AI Technical Summary

Problems solved by technology

[0020] In view of the above research problems, the purpose of the present invention is to provide a device and method for analyzing and querying alarm information based on time-series similarity, so as to solve the problem that the correlation mining of alarm information in the prior art is based on the co-occurrence of alarm information in historical data. There are not many alarm information co-occurrence data in the real data, and the coverage ratio of real related alarm information is very small. Without relevant alarm information, the operation and maintenance personnel cannot locate the fault and analyze the cause based on the relevant alarm information.
