Failure detection of the avionics system based on chaotic virtual collision of signals

In order to ensure the operation security of the integrated avionics system,a new model for failure detection is proposed. Firstly,according to the chaotic feature of the obtained data,a multi-dimensional collision model of the virtual area is introduced. Then,when the failure occurs,by utilizing the collision feature of avionics system data' chaotic change in space,the possible failure risks in the avionics systems are detected,so as to ensure the security detection of the system under the service availability condition. Finally, the QPME is applied in experimental simulation.It can be seen from the results of failure occurrence rate type distribution and recovery strategy,that this method can quantitatively analyze the impact of hardware and software failures on the safety performance and reduce the burden on the avionics system.
