Electronic circuit card and corresponding signal acquisition and generation system, including programmable digital matrix switches

Abstract

The invention relates to an electronic circuit card(1) and a corresponding data acquisition and generation system, including a conditioning circuit for conditioning input signals of at least two types chosen from the following types: digital, discrete, analog. A binary modulator(30) and resources(51,52) for processing the different types of input signals are provided. A programmable digital matrix switch(40) for input signals is used to route the input signals to the resources corresponding to the types of the signals. Alternatively, or additionally, the card(1) includes an output signal modulator and an output signal programmable digital matrix switch used to route the modulated output signals to an amplifier as a function of their type. The programmable digital matrix switches make it possible to address constraints regarding the segregation of varying numbers of input / output signals of different types.

Description

technical field [0001] The present invention relates generally to electronic cards and data generation acquisition systems comprising such cards, especially in the field of aviation. Background technique [0002] Aircraft are equipped with various electronic systems to ensure various functions that allow the aircraft to accomplish its mission. In particular, these electronic systems include signal generation acquisition systems to interface with multiple sensors and actuators. These signals include different types of signals, especially discrete input signals DSI and discrete output signals DSO; analog signals such as ANI-DC signals for DC analog input signals, ANI-AC signals for AC analog input signals, analog output Signal ANO; or digital input / output signal, such as ARINC429 signal. ARINC429 is an aviation specification for transmitting digital data. [0003] Known signal generation acquisition systems of the prior art use electronic circuits dedicated to each input / ou...

AI Technical Summary

Problems solved by technology

similarly, it is also very complex to use the data generation acquisition system again for equipping aircraft that do not have the same number and type of inputs / outputs to process

[0005] Furthermore, it was found that often a card from an aircraft's data generation acquisition system cannot be re-used to implement another aircraft's system because the signal separation constraints are different between the two aircraft
