摘要
AFDX(avionics full-Duplex switched ethernet)作为新型航空总线技术,已经在空客A380/400M、波音B787等飞机上得到成功应用;AFDX网络的出现为航空电子系统的发展提供了一种高实时性和可靠性的解决方案;如何有效论证一个AFDX网络系统的实时性和可靠性成为了AFDX网络系统测试方面的一个重要课题;通过采用数据收发,网络监控和故障注入的方式对AFDX网络系统的可靠性进行有效的评测,实现了一种AFDX网络系统测试和评估系统;经过测试,该测试系统可以有效地对AFDX网络系统的可靠性进行评估和测试。
As a new type of aviation bus technology,AFDX（Avionics Full-Duplex Switched Ethernet）has been successfully applied to Airbus A380/400 M,Boeing B787 and other aircraft.The emergence of the AFDX network provides a high real-time and reliability solution for the development of the avionics system.How to effectively demonstrate the reliability of a AFDX network system has become a major issue in the AFDX network system testing.Through the use of data transceiver,network monitoring and fault injection,the reliability of AFDX network system is evaluated effectively,and a AFDX network system test and evaluation system is implemented.After testing,the test system can effectively evaluate and test the reliability of AFDX network system.
