To comply with the requirement of the transmission speed, robust and compatibility of the aircraft, and also lower the cost and research cycle, a deterministic network is defined by AFDX( avionics full duplex switched ehtemet) which is formed by Airbus based on COTS hardware products. In the research development progress of new generation aerocraft, avionics system that is the most important part of airbus is seemed as the brain and nerve centre of airbus, furthermore AFDX( avionics full duplex switched ethernet) network is the hinge and core of the avionics system. Because the performance of AFDX end system influences the transmission speed of the avionics directly, integrated tests should be taken to ensure the performance of the end system. Therefore, it presents a test technique for the AFDX end system, and illustrates the details about the association of the hardware and software along with the test method.%AFDX是为满足商用航空飞行器对高传输速率、健壮性和兼容性的要求,同时为降低成本,并缩短开发周期,空客公司充分利用商业货架COTS硬件产品形成的确定性网络.在新一代的飞机研制中,航空电子系统是大型客机系统的重要组成部分之一,是大型客机的大脑和神经中枢,丽AFDX网络是航空电子系统的枢纽和核心.在实际应用中,由于AFDX终端系统的性能指标直接影响着整个系统的传输性能,因此需要对AFDX终端系统的性能进行综合测试.为此,文中构建了一套AFDX终端系统的测试方法,并对其软硬件及测试方法进行了详细介绍.
