Abstract:

In order to satisfied requirements of the new generation airplane's integrated avionics ,the purpose of this subject is investigating generalized and standardized airborne remote intelligent interface data concentrator of the new generation airplane. In this paper, the function and principle of Airborne remote intelligent interface data concentrator has been systemically described. This article introduces emphatically the AFDX network communications, the high-speed analog signals conversion, the low signals modulation, the high-power signals transition and the interface software design. Finally, this thesis puts forward a implementation technology for a remote intelligent interface data concentrator. Airborne remote intelligent interface data concentrator has been validated in the new generation airplane’s integrated avionics system and this validation indicates that the remote intelligent interface data concentrator can collect signals from a sensor, transform the signals into data in Real-time and drive data to an actor.
