A Realization Method of Rail Transit Intelligent Early Warning Based on Correlation

Abstract

The invention discloses a rail transit intelligent early warning system based on an association relation and a realization method. A first association rule implicant form is generated according to the relation between the mimimal cut set of a fault tree and a top event. A data mining tool is used to dig the relation between the historical data in a history database, and a second association rule implicant form is generated. An expert evaluation system screens a third association rule implicant form, and a fault generation probability, a harm degree, an alarm grade and an alarm threshold are set. A background service module periodically each node state information. Finally the early warning is carried out through a man-machine interaction interface. The problem of the intelligent early warning of fault points with an association relation is solved, and a further link reaction is prevented. A process from a quantitative change to a qualitative change can be clearly displayed, and the early warning information is correct and timely. The association relation between faults is correctly and reasonably processed, the reliability and abundance of the early warning information are improved, and the safety of rail transit is established on active defense.

Description

technical field [0001] The invention belongs to the field of urban rail transit, and in particular relates to an intelligent early warning system for rail transit based on an association relationship and an implementation method. Background technique [0002] With the development of the economy, the rapid development of the rail transit industry. The normal operation of rail transit is inseparable from the cooperation of various systems, but the integration or interconnection of these systems brings new challenges to the safety of the entire system, and the intricate correlation between systems not only increases the difficulty of system processing , but also increases the probability of system failure. Practice has shown that although several isolated fault points have little impact, if there is a certain relationship between them and they are not properly dealt with, they may bring immeasurable harm to the safety of rail transit systems. The key to the occurrence of this...

Problems solved by technology

[0003] At present, the alarm system only warns the equipment or equipment point that a failure has occurred in the form of an entity or a computer graphic element after a failure occurs, and does not further prompt the status information of other failure points associated with the failure point. This method is passive and single, and does not reflect Features such as fault point timing cannot be applied to the huge multi-level and multi-application system of rail transit
