综合化模块化航空电子架构航电系统飞行管理模块的设计

为了能够采用综合化模块化航空电子(integrated modular avionics,IMA)架构,达到简化系统设计、开发和验证过程,提升航电系统的安全性与可靠性的目的,针对当今主流的IMA架构的航空电子系统中的综合处理计算机系统,介绍了其中的飞行管理系统(flight management system,FMS)计算机现场可更换模块和IMA系统软件架构,使用符合ARINC653标准的天脉2(TM2)嵌入式操作系统作为软件开发平台进行飞行管理模块的平台软件、应用软件设计和分区集成,并通过系统级仿真验证证明其功能满足设计需求,有助于实现在IMA架构下飞行管理系统的具体型号应用.

Design of IMA Architecture Avionic System Flight Management Module

In order to adapt the architecture of Integrated Modular Avionics (IMA) system, to achieve the purpose of simplify the system design, development and verification process, and improve the safety and reliability of the avionics system. Therefore, as the mainstream part of IMA system, Flight Management System (FMS) of integrated processing computer had been studied. The hardware design and software architecture of Line Replaceable Module for FMS were introduced, firstly. With TM2, the embedded operating system which confirmed ARINC653 standard, as development platform, function design and implementation of FMS were also discussed. Finally, the study meets design requirements has been verified by system level simulation verification, and specific model accomplishment of FMS for IMA system has been improved.
