摘要
目的:研究一种基于故障树分析理论的监护仪故障诊断方法,该方法可为医疗设备维修人员提供比较准确的故障排除引导策略,以期降低维修成本和提高维修效率。方法:利用故障树理论和大量实际维修工作经验,针对同类故障现象及其可能的故障成因,建立典型故障树分析模型并进行各项概率事件的量化分析,最终得出故障成因判断结论。结果:通过对监护仪某一类故障成因的充分研究分析,体现了故障树理论的准确性、易用性和实用性,能引导维修工程师快速有效地判断和解决故障。结论:该方法的运用能够较为直观地表明引起故障的成因及其出现概率,对监护仪的快捷、准确维修有很大的帮助,也起到了辅助与培养设备维修工程师的作用。
Objective To propose a monitor failure diagnosis method based on fault tree theory to decrease maintenance cost and increase efficiency.Methods Based on fault tree theory and maintenance practices,a typical fault tree analytical model was established on likely faults and possible causes.The model developed was applied to the quantitative analyses of kinds of probability events to determine the causes for the faults.Results The study on some kind of faults proved the accuracy,accessibility and practicability,which facilitated the maintainer to eliminate the fault.Conclusion The method determins the cause and probability of the fault directly,and contributes to rapid and convenient maintenance of the monitor.
