基于MBSE在航空电子通信系统中的应用

Application of MBSE in Avionics Communication Systems

在航空电子通信系统的研发过程中,针对基于文档的传统开发方法中存在的开发周期长、需求验证困难以及更改流程复杂等问题,文中提出了应用基于模型的系统工程(MBSE)方法。基于航空航天领域中主流的Harmony方法,通过需求分析、功能分析和设计综合依次建立了需求模型、功能模型和物理架构模型。该方法保证了数据的可追溯性,提高了设计效率,降低了设计风险,可为MBSE方法在航电系统中的进一步应用提供参考。

The traditional methods based on documents are confronted with a variety of problems,such as long periods of development,difficult verification of requirement and complex procedure of alteration. To address the challenges in the development of avionics communication system,this paper proposes a model-based systems engineering（ MBSE） method. Based on the dominant Harmony method in the aerospace field,the requirement model,function model and physical structure model are built respectively through the requirement analysis,function analysis and design synthesis. This method not only ensures the traceability of data,but also improves the design efficiency and reduces the design risk of the project,hence providing references for the further utilization in the avionics system.
