基于故障诊断价值测度的检测点优化配置方法

Research of test node selecting for fault diagnosis based on value measure

针对故障诊断中的检测点优选问题,提出了一种新的检测点故障诊断价值测度方法。该方法引入了收益因子及成本罚数,考虑了检测点诊断收益及测量成本两个因素对测点选择的影响。通过给出一个典型的故障诊断例子,说明了新方法能够全面地评判检测点的故障诊断价值,较原有的方法有了较大的改进,更适合工程需要。

The problem of test node selecting in fault diagnosis is studied based on the diagnosis value measure. First, a new value measure method for test node selecting is developed, and by adopting benefit factor and penalty constant, the impact of diagnosis profit and measure cost upon test node selecting is studied. Finally, the test node selecting results of a typical fault diagnosis system show that the method is more effective than original method and more fits the reality.
