一种基于离散量配置方案的硬件资源识别容错设计技术

A Fault Tolerant Design Technique for Hardware Resource Identification Based on Discrete Quantity Allocation Scheme

综合模块化航空电子系统通过可配置的共享硬件资源技术大幅提升了系统任务可靠度。但此类多资源余度系统的硬件资源存在位置识别冲突,会导致余度系统整体性共因失效风险。提出了一种基于离散量配置方案的硬件资源识别容错设计技术,可有效避免单一失效导致的系统整体性功能丧失,并采用任务可靠性分析和安全性分析方法对其有效性进行了验证。

The integrated modular avionics system greatly improves the mission reliability of the system through configurable shared hardware resource technology. However, the hardware resources of this kind of multi-resource redundancy system have the common failure risk caused by location recognition conflict. A fault tolerant design technique is presented for hardware resource identification based on discrete quantity allocation scheme. This technique can effectively avoid the loss of overall system function caused by a single failure. The effectiveness of the method is verified by reliability analysis and security analysis.
