主动诊断的目的是通过在运行时计算诊断信息进行故障隔离和在线错误恢复，从而显著提高系统的可靠性。所提出的工作扩展了语义技术，通常用于大型IT系统，主动诊断在开放的嵌入式真实的时间系统。开放嵌入式系统（例如，老年人护理、关键基础设施、健康管理和医疗系统的环境辅助生活）表现出实时和可靠性要求，而组成部件在设计时是未知的。时间触发的诊断推理支持症状的增量生成，这是诊断分析过程的时间和空间分解的结果。的方法和算法的原型实现，以及实验评估。本文表明，动态语义Web服务与时间触发调度技术相结合，使主动诊断在开放的嵌入式系统的可靠性和实时性的要求是合适的。
Active diagnosis aims at significantly improving system reliability by computing diagnostic information at run-time for fault isolation and online error recovery. The presented work extends semantic techniques, usually used in large-scale IT systems, for active diagnosis in open embedded real time systems. Open embedded systems (e.g., ambient assisted living for elderly care, critical infrastructures, health management and medical systems) exhibit real-time and reliability requirements, while the constituent components are unknown at design time. Time-triggered diagnostic inference supports the incremental generation of symptoms, which result from the temporal and spatial decomposition of the diagnostic analysis process. The methods and algorithms are prototypically implemented, as well as experimentally evaluated. The paper demonstrates that dynamic semantic web services in combination with time-triggered scheduling techniques are suitable to enable active diagnosis in open embedded systems with reliability and real-time requirements.
