摘要
在叶片振动故障监测过程中 ,单传感器的间断相位法只能测得叶片振幅值信息 ,本文应用两个传感器的信息融合技术 ,通过多源信息的综合、分析和推理 ,得出了叶片振动频率信息 ,提高了传感器系统的有效性 ,消除了单个传感器的局限性。
In the process of fault monitoring of blade vibration,tip-timing method with single sensor only can detect amplitude information of the blade. By applying data fusion technique with two pieces of sensors,through synthesizing,analyzing and reasoning of multi-resources information,acquired frequency information of the blade. Therefore,it improves effectiveness of sensors system,and eliminate disadvantage with single sensor.
