AFDX网络配置驱动的PCI总线远程数据采集器设计

Design of a Table-Driven AFDX Remote Data Concentrator Based on PCI Bus

摘要:

针对先进飞机的航电系统架构,文章提出一种基于PCI总线的模块化远程数据采集器设计,以AFDX网络为主干网络,配置了ARINC825总线、ARINC429总线、多路传感器和作动器I/O接口,从多接口、配置引脚和配置驱动3个方面进行了软硬件设计及实现,保证了远程数据采集器的可靠性、灵活性和可维护性,并通过试验,对文章设计的远程数据采集器的功能指标和时延参数进行了测试,测试结果表明,文章提出的设计,能够满足远程数据采集器功能需求,并具备转换时延小的特点。

Abstract:

Based on the avionics system structure of most advanced airplane , this paper put forward a design of multi-modules Remote Data Concentrator based on PCI bus, which uses AFDX as its backbone network , and also have multiple ARINC825 bus interfaces, ARINC429 bus interfaces, sensor and actuator I/O interfaces, implement the hardware and software with multi-interfaces, configuration Pins and table-driven design, which improve the reliability,flexibility and maintainability of Remote Data Concentrator, finally, test the function and latency of the designed RDC, the test results show that the proposed design is a low latency and full functional design.
