System for selecting an item of data representing a parameter of the air, engine control system, aircraft comprising such systems and associated method

摘要

A system and method for selecting a datum representative of an air parameter, including a plurality of sources each capable of delivering a datum representative of a measured value of the parameter. The system includes: a mechanism for determining, for at least some sources, a number of other sources from the plurality of sources in agreement with a source in question; and a mechanism for selecting the datum selected from the data delivered by the sources for which the determined agreement number is the maximum. An engine control system, or an aircraft can include such a system or implement such a method.

1. A system for selecting a datum representative of an air parameter, comprising:
a plurality of redundant and independent sources that are each configured to deliver a datum representative of a measured value of the parameter; means for determining, for at least a concerned source, a number of other sources of the plurality of redundant and independent sources in agreement with the concerned source; and means for choosing the selected datum to be used in a control computer from among data delivered by the plurality of redundant and independent sources for which the determined agreement number is maximum, wherein the means for choosing the selected datum is configured to be inactive when:
the means for determining identifies at least four sources of the plurality of redundant and independent sources in agreement by pairs, andsources of one pair of the plurality of redundant and independent sources are not in agreement with sources of another pair of the plurality of redundant and independent sources.
