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,而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。
The AFDX is designed to meet the high transmission rates, robustness and compatibility requirements of commercial aircraft, and to reduce costs and shorten the development cycle, Airbus takes full advantage of the deterministic network of commercial shelf COTS hardware products. In the development of a new generation of aircraft, the avionics system is an important part of a large airliner system. It is the brain and nerve center of a large airliner. The AFDX network is the hub and core of avionics systems. In practical application, the performance of the AFDX terminal system directly affects the transmission performance of the entire system, so the performance of the AFDX terminal system needs to be tested comprehensively. For this reason, a set of testing methods of AFDX terminal system is built in this paper, and its hardware and software and testing methods are introduced in detail.
