摘要
FC接口网络被广泛应用在各型机载航电环境中,由于机载类型的差异和应用环境的不同,导致出现了种类繁多的FC接口单元,非常不利于前期设计生产和后期维护保障。提出了一种满足多种主流型号的统型机载FC接口单元,通过主机控制和片选不同的逻辑软件资源,实现在不同型号、不同环境中的互换使用。结合主机系统应用需求,给出了统型机载FC接口单元的系统架构和设计方案,分别详细阐述了FC接口、PCIE接口、逻辑加载配置和加载控制的设计。测试验证和工程应用表明,统型FC接口单元各项性能指标均满足系统要求。
FC interface network is widely used in various airborne avionics environments,various FC interface module are applied due to the differences in airborne types and application environments,this is very disadvantageous to the design,production,and maintenance.This paper presents a unified FC interface module which can be used in different airborne types and environments by controlling and selecting different logic software resources.Combined with the application requirementsof the host system,the architecture and scheme of unified FC interface module in avionic environment is introduced,the design of FC interface,PCIE interface,logic load configuration and reload control are described in detail.The test and engineering application show that all the performance indexes of the FC interface unit meet the requirements of the system.
