基于Rhapsody的综合航电火控系统图形化设计研究

Rhapsody-Based Graphic Design of Integrated Avionics Fire Control System

针对当前飞机综合航电火控系统设计使用传统文档开发方法的不足,借助基于模型的系统工程思想,提出了基于Rhapsody的面向对象的图形化系统设计方法,并给出了具体的设计思路与实施步骤。通过某飞机典型作战过程的实例应用,详细研究了Rhapsody图形化系统设计方法中各种图例的应用场景和使用方法,并将各设计阶段应用图例通过功能传递进行关联,梳理出一套完整的复杂系统设计方法。该方法能够实现系统的迭代优化,减少工作量,缩短开发周期,可为今后复杂系统的图形化设计提供参考。

To overcome the shortcomings of the traditional document methods used in the design of the integrated avionics fire control system, with the aid of the model-based system engineering theory, a method for object-oriented graphic system design based on Rhapsody is proposed. The specific design procedure and implementation steps are given. Taking a typical combat process of a certain aircraft for instance, this paper studies the application scenario and usage of various legends in the design of Rhapsody graphic system in detail, connects the legends in each designing stage with each other through function transference, and works out a complete design method for complex system. This method can realize the iteration optimization of the system, reduce workload and shorten the development cycle, which can serve as a reference for the graphic design of complex systems in the future.
