AFDX网络测试技术研究与实现

Research and Implementation of AFDX Network Test Technology

近年来,航空电子全双工交换式以太网(AFDX)是使用广泛的新一代航空总线;国内对其研究缺乏相关技术支持;传统AFDX网络测试技术存在数据交互测试准确性差、测试时间长、人员开销大、测试数据层深度匮乏等问题,针对上述问题形成的原因,提出AFDX网络测试3+1整合法设计;采用数据整流测试技术(DVSER)、动态特征交互绑定技术(HDBD)与数据智能定位技术(HGYD)对产生的问题进行针对性解决;通过仿真实验测试证明,提出的AFDX网络测试3+1整合法的各项测试数据优于传统测试方法。

Avionics full duplex switched Ethernet （AFDX） is widely used in recent years a new generation of aviation bus. Domestic re-search on the lack of related technical support. Traditional AFDX network data interaction testing technology in testing accuracy is poor, long test time,staff costs, such problems as lack of test data layer depths formation reasons for these problems＇ puts forward AFDX network test 3＋1 whole legal design. Using test data rectification technology （DVSER） , the dynamic characteristics of the interactive data binding tech-nology （IIDBD） and intelligent positioning technology （IIGYD） for targeted to solve problems. Through the simulation test proves that the proposed AFDX network testing every test data of 3 ＋ 1 whole legal due to the traditional test method.
