航空电子全双工交换式以太网故障注入方法研究

航空电子全双工交换式以太网(AFDX)是成功应用于新一代大型飞机的新型航空数据总线.针对AFDX适航性及网络容错性能研究的需要,开展了有关AFDX网络故障注入方法的研究.在AFDX实验系统上,通过软件方法进行动态故障注入,测试AFDX网络对注入故障的响应,验证了AFDX网络的可靠性、健壮性及容错性能,并为进一步研究AFDX网络性能及故障诊断提供了大量测试数据,对深入开展AFDX适航技术研究打下了基础.

Research on Fault Injection on AFDX

AFDX is a new aviation data bus,which has been successfully applied to the new generation airplanes.For the needs of the research on network fault tolerance performance and airworthiness of AFDX,the study on the method of AFDX fault injection is carried out.On the AFDX experimental system,AFDX responses to fault injection by software are recorded,and the reliability,robustness and fault tolerance performance of AFDX network are verified.The experiment also provides a large number of testing data to further study AFDX network performance and fault diagnosis,which lays a foundation for further research on the AFDX airworthiness technology.
