软件失效及软硬件交互故障是核电厂全数字化仪控系统故障的主要来源之一。现有基于硬件的状态监测机制应对这一新型失效模式存在不足。应用系统理论事故建模与处理(STAMP)模型,对核电厂全数字化仪控系统的失效模式进行初步分析,提出将软件、硬件及其交互作为监测对象,建立一种整合软、硬件状态的全状态监测机制,为系统状态监测提供多样性及预警能力,对提高核电厂数字化仪控系统的安全性具有重要意义。

The digital control system has been wildly applied in nuclear power plant. Being the key safety component in system, Software may lead to software failure and dysfunctional interactions among software and hardware components. The current hardware status monitoring mechanism can't deal with this new failure mode in a perfect way. This paper applied the STAMP to analysis the failure mode in NPP digital system firstly, take the software, hardware and the interactions as research objects, and propose a new system merged-status monitoring mechanism at last which considers that all status informatio...
