综合模块化航电系统软件技术研究

Technical Research of Integrated Modular Avionics

从软件可靠性的角度对综合模块化航电(IMA)系统进行了讨论。从IMA系统的体系结构入手,研究了软件接口定义以及系统失效。具体分析了IMA软件研制过程中各角色的作用以及这种责任的分散所带来的问题。结合国内的发展现状,探讨了IMA系统测试各层次内容,为国内正在进行的四代机项目的研制及测试工作提供了一些思路。

The integrated modular avionics（IMA） is discussed from the perspective of software reliability.Firstly,starting from the architecture of integrated modular avionics,the definition of software interface and System failure are researched.The roles in the development process of IMA software and the problems brought about by this frag-mentation of responsibilities are analyzed.Finally,according to the status of domestic development,the content of all levels of the IMA system testing is explored and some ideas for the ongoing development and testing work of d-omestic four-generation flight project is provided.
