磨煤机故障诊断中多传感器信息融合技术的应用

Fault Diagnosis on the Coal Pulverizer with Multisensor Information Fusion Technique

针对磨煤机故障诊断系统出现“漏报”、“误报”现象,提出应用多传感器信息融合技术,并给出了多传感器信息融合模型。该模型可提高对磨煤机的工作状态和故障的识别能力,同时降低监测与故障诊断系统的成本。

The system of fault diagnosis on the coal pulverizer sometimes loses to report the fault or wrongly reports it. In view of these problems, the multisensor information fusion technology is introduced, and the multisensor information fusion model is put forward. This model can improve the recognization to the working state and fault of the coal pulverizer ,and decrease the cost of the state monitoring and fault diagnosis system at the same time.
