【摘要】 在先进飞机电气系统采用分布式配电和负载自动管理技术是当前发展的必然趋势。本文在对先进飞机电气系统结构及功能详细分析的基础上,对系统顶层软件的功能进行了分析研究,并重点论述了仿真软件的实现。 配电自动化过程是个多任务并发过程,如何协调各任务的运行,提高系统运行效率,是仿真软件的关键。本文从仿真软件的功能出发,论述了系统任务的划分,并结合Windows消息驱动机制和多线程概念,提出了一种Windows环境下实现多任务管理的方法;同时,本文从实时数据库和线程安全类概念出发,论述了一种用于管理系统运行过程中公用数据的简易的内存数据库管理系统,两者的结合很好的解决了上述问题。 另外,本文还对系统支持软件的设计工作作了介绍,支持软件包括参数配置和图形编辑两个部分,参数配置软件用于系统运行之前的参数配置,使得仿真软件呈现一定的自动化特征;图形编辑软件支持用户自定义图元并提供与数据库接口,使用户能定制具有动态功能的电气系统流程画面。 仿真软件是在Windows操作系统下采用Visual C++开发,人机界面友好,操作简易。联机调试工作基本完毕,结果表明,系统运行可靠,达到了功能要求,性能良好,具有很好的仿真效果。

【Abstract】 It is an inevitable trend that Distributed Power and automatic load management technologies will be applied in Advanced Aircraft Power System(AAPS). Based on the detailed analyses of Advanced Aircraft Power System construction and function, this paper discusses the function analyses of system top software and presents the realization of the simulation software. Automatic power distribution is a process with multiple intercurrent tasks. So the key of the simulation software is how to harmonize the run of various tasks and to raise the efficiency of the system. This paper presents the disassemble of the system task according to the function of the simulation software and brings forward a way on how to realize the multiple tasks management under the Windows circumstance based on the information drive mechanism and multithreading concept of Windows. Meanwhile, from the real time database and thread security concept, this paper discusses a simple EMS database management system used in the public data of management system process. The harmonious integration of two ways above perfectly solves the issues of the simulation software. Also, the paper presents the design work of system auxiliary software, which includes the data configuration and the graphics edit. The data configuration software is used in the parameter configuration before the start of system and can make the simulation software own some automatization features. Graphics edit software allows users to define the basic drawing element and provides the access to database, which make it possible for the customers to draw special power system flows with dynamic functions. By use of Visual C++, the simulation software is designed under Windows. The man-machine interface is very kind and it is easy to manipulate. The online debugging has completed. The result shows the system runs reliably and has achieved functional requirement as well as good performance and the simulation effect is excellent.
