一种新型的故障检测定位方法研究

针对大型复杂系统故障定位耗时长等问题,在分析故障树特征的基础上,改进了遗传算法,设计了基于故障树底事件的故障检测定位方法。该方法将顺序检测融入到改进的遗传算法检测当中,在工程应用领域体现了一定的优越性。仿真实验结果表明,该方法能够准确定位故障,有助于提高故障检测定位的效率。

A Late-model method of fault test and localization

Aiming at the problem of consuming long time in fault localization at the large and complex system,on the basis of the characteristics about the fault tree analysis,improve genetic algorithm,this paper design a fault test localization method which based on the bottom events of fault tree.The method introduces the sequence test into the improved GA test,and exhibits preferable superiority in the field of the engineering application.The result expresses that the method can locate the fault accurately and can help to improve the efficiency of fault test and localization.
