故障树模块化在装甲车辆灭火系统故障诊断中的应用

The modularity of the fault tree in the application of the armored vehicle fire hydrant system fault diagnosis

摘要:

为了实现装甲装备灭火系统故障的快速诊断，提出了一种故障树模块化分析方法；对灭火系统故障树进行深度优先最左遍历，并记录遍历过程，按照遍历顺序对故障树中的每个事件进行标定，并将灭火系统故障树划分为相互独立的模块，依据划分的模块可以通过故障现象对模块内的故障进行排查及修复；实验结果分析表明，该方法可以快速修复模块故障，恢复系统功能，简化了以往对灭火系统所有子事件遍历查错的繁琐过程。该方法同样可以计算故障模块的失效概率，并可以实现故障模块的整体更换，恢复系统性能；证明了故障树模块化方法在灭火系统故障诊断中具有较高的效率，简化了灭火系统诊断流程，在装甲车辆其他系统故障诊断中具有借鉴作用，符合现代作战对于装备保障的需求。

Abstract:

In order to achieve rapid fault diagnosis of the armored equipment fire extinguishing system, this paper proposes a fault tree modular analysis method; By the way of traversing the fire extinguishing system fault tree with the depth first left most searching algorithm, the method calibrates the events of the fault tree, divides the fault tree events with the calibration sequence, and achieves the positioning of faults quickly; this article proves that the fault tree modular approach in fire extinguishing system fault diagnosis is of high efficiency, and the method meets the needs of operational support requirements to the modern warfare.
