摘要
该文基于VxWorks嵌入式实时操作系统,以机载配电系统为例,开展了机载软件设计的研究。首先简要介绍了VxWorks嵌入式实时操作系统,并通过横向对比,阐明了选其作为机载操作系统的原因;然后基于模块化的编程思想,规划了机载配电系统软件的基本架构,并详细阐述了软件模块设计以及基于离散函数的故障保护功能的实现方法;最后,通过实验验证了软件能够满足机载配电系统高实时性和高可靠性的要求。
Based on VxWorks embedded real-time operating system(RTOS),this paper takes the airborne power distribution system as an example to carry out the research of airborne software design.Firstly,VxWorks embedded RTOS is briefly introduced,and the reason of choosing VxWorks as airborne operating system is explained by horizontal comparison;Then,based on the idea of modular programming,the basic architecture of airborne power distribution system software is planned,and the design of software module and the realiza tion method of fault protection function based on discrete function are described in detail;Finally,it is verified by experiments that the software can meet the requirements of high real-time and high reliability of airborne power distribution system.
