一种内嵌软件传感器的双软总线体系结构研究

航空软件的逻辑结构和系统规模日趋庞大,软件可靠性保障已成为新一代航空电子综合化领域的研究热点;针对实时软件的状态监控与故障诊断问题,提出了一种基于构件技术的双软总线风格体系结构,采用面向对象方法予以建模,构建该体系结构的静态框架和动态行为,并探讨了软件传感器采集监控对象实时状态的详细设计;以某惯导系统软件为例,对双总线体系结构进行扩展和应用,实例说明了该体系结构有助于使可靠性保障软件的框架定义更加清晰,易于实现。

Research on a Soft Dual-Bus Architecture with Software Sensor Embedded

With the development of logical structure and system scale of Aviation software,how to guarantee the software reliability and safety will be a critical hotspot issue in the research for the new generation of integrated avionics system.Therefore,a new architecture which is based on component and soft dual-bus style is proposed to use for fault monitoring and detection of real-time software.This architecture is modeled by UML to build static structure and dynamic behaviors,brings forward a new software sensor to collect detecting data with detailed design.An application on fault diagnosis of INS/GNSS software system illustrates that the new method could make the software architecture design which is aimed at assuring reliability clearer and easier to achieve.
