Problems solved by technology

[0005] while the use of passive elements in an aircraft information network is considered reliable (the reliability of these elements is generally higher than that of avionics systems), the use of active elements can lead to a reduction in the overall reliability of avionics systems due to their reliability

Embodiment Construction

[0039] The invention relates to a central monitoring system that enables the diagnosis of the monitored systems and the functions implemented by these systems, and the generation and display of alarms to allow the operator to deal with degradation situations due to degradation of these functions.

[0040] The redundancy of the central monitoring system is preferably implemented by means of functions which are independent of each other. The method of monitoring a shared communication medium prioritizes this independent performance while fully ensuring performance compatibility of these independent functions.

[0041] The architecture of the monitored operating systems includes a communication medium that is shared between the different monitored operating systems and which in particular includes one or several active elements such as switches. It should be noted here that if the number of switches is too large, the number of configuration combinations that indicate possible fai...

Abstract

The invention relates to a method and a device for monitoring avionics systems connected to a shared medium. A preliminary phase is aimed at determining the conditions of activation of each alarm of each avionics system connected to the communication medium. These conditions are related to each avionics system and to the state of the communication medium. The monitoring phase comprises a step of determining the state of the elements of the communication medium and a step (455) of evaluating an indicator of the state of the communication medium on the basis of the state of the elements of the communication medium and on the basis of a predetermined formal modelling of the communication streams of the communication medium. An alarm is selected and activated (470) depending on the evaluated state of the communication medium and depending on a predetermined modelling of the consequences of the evaluated state of the communication medium on the operation of the avionics systems.

Description

technical field [0001] The present invention relates to the reliability of avionics systems, and more particularly to an apparatus and method for monitoring avionics systems connected to a shared medium. Background technique [0002] The reliability of avionics systems is a key concern of aircraft designers. The general consensus is that redundancy of critical equipment of an aircraft is necessary to ensure required functionality despite system failures and to compare system performance and rapidly detect possible failures. [0003] The use of information systems in aircraft has prompted designers to implement information networks for the transfer of information and instructions between operating systems. An information network is here considered as a shared communication medium for exchanging data. The capacity of these media is determined by the characteristics of the data being transferred, especially their volume and speed. [0004] The use of active elements such as ...
