Abstract

The invention discloses a system for analyzing coupling risks in failure behaviors of an integrated avionics system under big data environment. The system comprises a failure risk coupling extracting unit and a key failure behavior determining unit; the failure risk coupling extracting unit can extract association relationship existed among failure behaviors items; the key failure behavior determining unit can determine key failure behavior items in the association relationship. The system of the invention can analyze risks that cause failures in the integrated avionics system when coupling exists in some failure behaviors of the integrated avionics system, and realizes bid data mining of the integrated avionics system.

Description

technical field [0001] The present invention relates to the risk analysis of fault behavior in an avionics integrated system, and more particularly refers to a fault behavior coupling analysis system suitable for avionics integrated systems in a big data environment. Background technique [0002] As an integrated information system organism, the avionics integrated system must cover the information chain composed of information acquisition, transmission, processing and application. In order to obtain information superiority, it is necessary to adopt advanced technology in each link in the information chain, tap the potential, and make the system play the best performance. [0003] The integration of the avionics integrated system should integrate all the avionics components as a whole according to the combat technical requirements of the system, so that various system resources can be organically combined, coordinated work, and jointly complete the mission tasks of the syste...
