Abstract

The invention provides a method and system for analyzing alarm correlation based on network and time. The method comprises the following steps: normalizing and converting all alarms in a unified format; and grouping the alarms in accordance with network correlation and on the basis of network configuration information; performing window inspection on each alarm group in accordance with time correlation and analyzing the alarm groups exceeding a time widow; and carrying out pattern matching analysis on alarms with an improved event tree model, and releasing root alarms. According to the invention, the problem that an existing system cannot perform comprehensive analysis can be solved, and the exact and efficient alarm correlation analysis is realized.

Description

technical field [0001] The invention relates to an alarm correlation analysis technology of a power communication network, in particular to an alarm correlation analysis method and system based on a network and time correlation mode. Background technique [0002] In the power communication network, when communication equipment fails, a large number of alarms will be generated. Operation and maintenance personnel need to find out the main alarms from the large number of alarms, judge the cause of the failure based on the alarms, and analyze which services are affected. However, an alarm is an external manifestation of a fault, which has the characteristics of transitivity and multi-faceted expression. The fault is the cause, and the alarm is the result; the alarm is observable and easy to obtain, but the fault is usually hidden behind a large number of alarm messages. [0003] For a large number of output alarm information, in order to effectively provide useful information a...
