摘要:
针对智能电能表在可靠性预计中普遍依赖预计手册,难以有效结合故障模式、影响及危害性分析(FMECA)、故障树分析(FTA)等可靠性分析手段来指导改进;且在故障分析与改进中过多依赖人工经验、不够底层,难以保证分析结果的全面性与准确性等问题,提出了一种基于失效物理(PoF)的综合分析方法。首先,对涉及到的电子元器件进行失效机理分析并构建多失效机理下的可靠性预计模型,获取元器件的失效率数据。之后以此为数据基础进行FMECA与FTA相结合的综合分析,确定设计薄弱点。最后结合设计薄弱点的失效机理,给出针对性改进措施。以某型智能电能表的计量模块为例进行分析,综合分析中的FMECA与FTA结果一致、互为验证,并给出了具体改进措施,证明了此方法的可行性。
Abstract:
In response to the widespread reliance on estimation manuals for reliability prediction of smart electricity meters, which struggle to effectively integrate reliability analysis methods such as Failure Mode, Effects, and Criticality Analysis (FMECA) and Fault Tree Analysis (FTA) to guide improvements, and the over-reliance on human experience and lack of depth in fault analysis and improvement that hampers the comprehensiveness and accuracy of the analysis results, this paper proposes an integrated analysis method based on Physics of Failure (PoF). Firstly, failure mechanisms of the involved electronic components are analyzed, and a reliability prediction model under multiple failure mechanisms is constructed to obtain the failure rate data of the components. Subsequently, an integrated analysis combining FMECA and FTA is conducted based on this data to identify design weaknesses. Finally, targeted improvement measures are proposed by integrating the failure mechanisms of the design weaknesses. Taking the measurement module of a certain type of smart electricity meter as an example for analysis, the results of FMECA and FTA in the integrated analysis are consistent and mutually validating, and specific improvement measures are provided, demonstrating the feasibility of this method.
