Electronic circuit for determining an item of data representing a parameter of the air and system comprising such a circuit

摘要

An electronic circuit, and a system including such a circuit, for determining a datum representative of a parameter of air surrounding an aircraft, including: a mechanism receiving, from a plurality of sources, a plurality of respective measurement data representative of a measured value of the parameter; a mechanism determining the datum representative of the parameter based on the measurement data; and a mechanism transmitting the datum representative of the parameter to a computer associated with an aircraft engine.

1. An electronic circuit for determining a datum representative of a parameter of air surrounding an aircraft, comprising:
a first processor configured to
receive, from a plurality of sources, respective measurement data representative of a measured value of the parameter of air surrounding the aircraft,determine the datum representative of the parameter of air surrounding the aircraft based on the measurement data from the plurality of sources, andtransmit the determined datum representative of the parameter of air surrounding the aircraft only to a first computer associated with a first engine of the aircraft,wherein the first processor performs the determining of the datum representative of the parameter of air surrounding the aircraft by comparing the measurement data from the plurality of sources and by selecting the datum representative of the parameter of air surrounding the aircraft from among the measurement data from the plurality of sources, and a second processor, different from said first processor, configured to
receive, from the plurality of sources, the respective measurement data representative of the measured value of the parameter of air surrounding the aircraft,determine the datum representative of the parameter of air surrounding the aircraft based on the measurement data from the plurality of sources, andtransmit said determined datum representative of the parameter of air surrounding the aircraft only to a second computer, different from said first computer, associated with a second engine of the aircraft, wherein said determined datum representative of the parameter of air surrounding the aircraft transmitted to said first computer associated with said first engine is the same as said determined datum representative of the parameter of air surrounding the aircraft transmitted to said second computer associated with said second engine.
