摘要
综合模块化航空电子(IMA)架构具有成本低、高度灵活性和易扩展性等特点,已被越来越多的飞机采用。远程数据接口单元提供接口资源,它是IMA平台的重要设备之一。可配置的远程数据接口单元对降低飞机的成本有着巨大的好处。对比了联合式航空电子和IMA架构,并研究远程数据接口单元的需求;从需求出发,基于DO-297标准定义的IMA特点,提出了远程数据接口单元的设计思路;然后基于当前行业水平和工程经验,提出了三种可行的设计方案。
Integrated Modular Avionics （IMA） architecture is adopted by more and more aircrafts because of its benefit of low cost, high flexibility and easy extensibility. Remote Data Interface Unit provides interface resource, which is one of the key devices of IMA platform. ARDIU＇s characteristic of configurability can lower the cost of aircraft. Federated architecture is compared to IMA architecture, and the requirements of IMA are studied. A feasible design idea based on DO-297 is provided to meet the requirements and three solutions are proposed to implement the idea with engineering experience and best practice of avionic industry.
