摘要
近年来,国内外对于软件的失效模式与影响分析(SFMEA)越来越关注,相继颁布了一系列的标准。依据GJB 1391中给出的软件失效模式与影响分析方法,以智能温度变送器软件为分析对象进行可靠性分析,并将分析结果用于指导软件开发的后期工作。分析结果表明,智能温度变送器中温度计算软件模块的失效是影响系统的关键环节,分析结果有利于软件设计等后期开发过程有针对性地执行可靠性活动。
In resent years, the software failure mode and effect analysis （SFMEA） has been more and more concerned about at home and abroad, and a series of standards have been released. In accordance with the method given by GJB 1391, with intelligent temperature transmitter as the analysis object, the reliability analysis is conducted, and the result of analysis is used to guide the post procedures of software development. The results of analysis show that the failure of the temperature calculation module of intelligent temperature transmitter in detection mode is the key factor affecting the system; the analysis result is useful in post procedures of software design and other activities focused on the reliability.
