Le diagnostic de système de systèmes : une approche à base de modèles appliquée aux bancs d’intégration avionique

Abstract : The aim of this thesis is to study the diagnostic of test systems used at Airbus HELICOPTERS called avionics test benches. Helicopters embark twenty features to offer helicopter customers functions that will enable to operate the aircraft in all flight conditions (reduced visibility, restricted area, hostile terrain, in a combat zone). Integration tests are used to validate the embedded system with regards to a set of requirements defined by the European and US certification authorities. The state of avionics subsystems is assessed within the overall system, that is to say, using simulation of the real environment of the helicopter. AIRBUS HELICOPTERS wants to reduce the cost of the tests of the helicopter, preliminary testing in a simulated environment, called integration benches. The integration bench must be compliant with the various configurations of the helicopter and simulation environment.We are interested in this thesis in the diagnosis of avionics integration bench. The implementation of diagnostic methods is essential to identify the causes of failures of integration benches. We work on a diagnostic model adapted to the integration bench. functional and structural diagnostic concepts were defined and used for the establishment of a diagnostic algorithm. We have defined verfications functions we have integrate on test benches to validate our method.
