民用飞机航电接口正向设计方法研究

Research on forward design method for civil aircraft avionics interface

基于采用综合模块化航电系统的民用飞机,提出了一种由功能接口定义到物理接口定义的机载系统航电接口定义正向设计方法。首先对接口进行了分类定义,阐述了航电接口设计过程与民用飞机全生命周期各研制阶段的对应关系。针对功能接口定义,提出了一种使用Capella建模工具的接口设计方法。针对航电接口定义(包括软硬件定义、端口定义和传输数据定义等),提供了设计过程、流程和方法。最后,结合该航电接口定义正向设计方法给出了具体案例供工程实施参考。

This paper provides a forward design process of avionics interface definition for civil aircraft using integrated modular avionics,which is from functional interface definition to physical interface definition.This paper first defines the interface category and expounds the corresponding relationship between the avionics interface design process and the development stages of civil aircraft in the whole life cycle.For functional interface definition,an interface design method using modeling tool Capella was proposed.For avionics interface definition(including hardware and software definition,port definition,transmitted data definition and etc.),the design procedure,process and method were provided.At the end of the paper,combined with the forward design method of the avionics interface definition,a specific case was given for engineering implementation reference.
