A Greedy Algorithm-based Cable Fault Diagnosis Method for Avionics Systems

In order to quickly and accurately detect the health condition of network cables in complex avionics systems, this paper proposes a greedy algorithm-based fault diagnosis method for a network cable of Avionics systems. This paper designs a semi-physical model test system based on Ethernet communication, which can be divided into two parts such as software control and hardware implementation. The results of the semi-physical model test show that the fast test step using Ethernet communication and greedy algorithm can quickly and accurately determine the health condition of the cables in the AFDX network cable test model. It is expected that the diagnosis and test method for the complex network is meaningful to improve the reliability of avionics system.
