Methodology and Application of Meta-Diagnosis on Avionics Test Benches.
Résumé
This paper addresses Model Based Diagnosis for the test of avionics systems that combines aeronautic computers with simulation software. Just like the aircraft, those systems are complex since additional tools, equipments and simulation software are needed to be consistent with the test requirements. We propose a structural diagnostic framework based on the lattice concept to reduce the time of unscheduled maintenance when the tests cannot be performed. Here, we also describe a diagnosis algorithm that is based on the formal lattice description and designed for test systems. The benefits is to capture the system structure and communication specificities to diagnose the configuration, the equipments, the connections, and the simulation software.
