Fault event analysis system and its analysis method

Abstract

The present invention discloses a fault event analysis system and its analysis method. The system includes a storage module, an event setting module and a calculation module. The storage module is used to store a fault tree component, and the event setting module is used to use the fault tree The component is used to generate a fault tree structure, and is used to input a plurality of event information to be set in each node of the fault tree structure, and is used to trigger logical selection and set events between each node and at least one child node from each event Trigger logic, the calculation module calculates the occurrence probability of the top event information to which the root node of the fault tree structure belongs according to the fault tree structure and each event trigger logic.

Description

technical field [0001] The present invention relates to a fault tree structure and an event analysis method through the fault tree, in particular to modularizing the fault tree to form various fault event analysis systems and analysis methods. Background technique [0002] Fault Tree Analysis is mainly an event analysis tool used to present the hierarchical relationship of events and obtain the probability of occurrence of the top event. Traditionally, there are many types of components in the fault tree, and the derivative conditions are set differently in response to different events, so the calculation is quite complicated. Moreover, in the past to calculate the fault tree, it was necessary for experts to determine the fault tree of all possible events first, and delete the items that were considered repeatedly, and then assign the probability value for calculation and analysis. Once the number of possible events is wrong, or if duplicate possible events are determined, ...

Problems solved by technology

Once the number of possible events is wrong, or if duplicate possible events are determined, an incorrect fault tree will be constructed

Secondly, the fault tree is generated by the analyst based on the number of events and derivation levels viewed by the analyst. Therefore, each constructed fault tree structure is used independently, and each node and the connection design between nodes will be individually designed. Therefore, it cannot be applied or constructed as a fault tree for different conditions

Third, because each fault tree is used independently and designed individually, the complexity of program design is not only high, but also requires a large amount of data to be processed, which is not suitable for combining with the Internet
