Method for locating and repairing intermittent failures in communication structures of an aircraft

摘要

To locate an intermittent failure in a communication structure of an aircraft comprising equipment (101, 102, 103, 104, 105) interconnected by a wiring (115) forming a plurality of communication mediums (111, 112, 113, 114 ) shared, an analyzer (130): recovers an error report relating to transmission errors observed on each of said communication mediums; counts transmission errors, by type of error and by communication chain; calculates a median of the counts for communication chains comprising the same pair of wired equipment; and when, for a communication chain, the count exceeds a threshold equal to the median plus a predefined margin, generates an intermittent failure detection alarm in association with the communication chain which has caused the threshold to be exceeded. Thus, intermittent failures are easily located and repaired. Figure to be published with the abstract: Fig. 2
