摘要
针对民用飞机电源系统嵌入式软件的可移植性、可扩展性要求,提出基于统一建模语言(Unified Modeling Language,UML)的面向对象设计方法;针对不同硬件平台上软件开发周期长、成本高的问题,采用分层插件设计方法。按照UML设计的开发过程,建立系统需求的用例图、软件逻辑架构的静态结构模型和运行架构的动态行为模型;对电源系统进行实时健康监控,完成对输出的配电管理。实际使用证明,嵌入式软件具有良好的可移植性、扩展性,软硬件独立设计可缩短系统开发周期、降低成本,系统设计能够实现自身健康管理。
Focusing on portability and extensibility requirements of civil aircraft power supply system embedded software, a object-oriented design method based on Unified Modeling Language（ UML） was put forward. Considering the issues of the long cycle and high cost of software development, we adopted the hierarchical plug-in design method. According to the development process of UML design, the use case diagram of system requirement was established, the static structure model of logical framework and dynamic behavior model of logical framework were established for the software. Power supply system management of out-put was implemented via health monitoring of power supply system in real-time. Practical application showed that： 1） The embedded software has good portability and extensibility; 2） The independent design of software and hardware can shorten system development cycle and reduce the cost; and 3） The system design can implement health management of itself.
