摘要 AFDX高速网络试飞系统实时采集关键参数的需求,使得研发一种高速、实时、高可靠的AFDX数据采集器十分重要。提出了一种基于FPGA的数据采集器设计方案,充分考虑AFDX网络特有的完整性检查、余度管理、虚拟链路、带宽隔离和流量整形等关键技术,实现网络数据的实时采集、参数挑选和数据转发等功能。通过对AFDX数据采集器进行实测,证明该设备具有通用性强、可靠性高、实时性强、数据处理速率高等特点,完全满足AFDX网络数据采集的应用需求,是一款完全具有自主知识产权的采集设备,为国产化研制及大型飞机的试飞验证提供了有力保障。 AFDX high- speed flight network system needs real- time sampling key parameters, so research and development of a high- speed, real- time and high reliability AFDX data acquisition are particularly important. This paper presents a FPGA- based data acquisition designed to take full account of the specific AFDX network technology, such as integrity checking, redundancy man-agement, virtual link, bandwidth isolation and traffic shaping. It has achieved real- time collection of network data, parameter selec-tion and data forwarding functions. By the test of AFDX data acquisition, it is proved that the equipment has the characteristics of versatility, high reliability, real- time, high speed data processing and so on. The data collector which is fully meet the application requirements of the AFDX network data acquisition has completely independent intellectual property rights, and provides a strong guarantee for the development of the nationalization and the flight test of large aircraft.
