面向切面思想的无线电通信导航监视系统设计与分析

Aspect-Oriented Analysis and Design of Airborne Communication Navigation and Surveillance System

摘要:

摘要：以机载无线电通信导航监视（CNS）领域综合化设计为背景，解决系统综合后复杂度高、维护性差、适航难度大等问题，提出了面向切面思想的系统设计方法。该方法基于软件设计领域的面向切面思想，首先从系统的领域模型、业务模型、关注点分离三个维度进行机载CNS系统需求分析，然后从系统架构设计、组件设计、组件编制、运行部署四个过程进行机载CNS系统设计，最后以真实案例介绍了通过新增功能模块和修改系统蓝图实现需求变更的过程。面向切面思想的综合化CNS 系统从可维护性和适航符合性两个方面进行综合评估，可以得出本文提出的方法能够提升系统的维护性，有助与产品适航符合性验证，可以为射频综合CNS系统适航性研究奠定基础。

Abstract:

Abstract:Based on the integrated design in the field of airborne radio communication, navigation and surveillance (CNS), a system design method based on aspect oriented idea is proposed to solve the problems of high complexity, poor maintainability and great airworthiness after system integration. Based on the aspect oriented idea in the field of software design, this method first analyzes the requirements of airborne CNS system from the three dimensions of system domain model, business model and separation of concerns, and then designs airborne CNS system from the four processes of system architecture design, component design, component preparation and operation deployment,Finally, a real case is introduced to realize the process of requirement change through adding functional modules and modifying the system blueprint.Through the comprehensive evaluation of the aspect oriented integrated CNS system from the two aspects of maintainability and airworthiness compliance, it can be concluded that the method proposed in this paper can improve the maintainability of the system, contribute to the verification of product airworthiness compliance, and lay a foundation for the airworthiness research of RF integrated CNS system.
