基于模糊信息融合的电梯故障诊断研究

Study on fault diagnosis of elevator based on fuzzy information fusion

针对电梯工作状态的综合性和复杂性,为了提高其故障诊断准确率,采用多信息融合技术进行电梯故障诊断,建立了基于模糊信息融合的电梯故障诊断模型,并将此诊断模型用于电梯驱动系统的故障诊断。通过对单传感器诊断结果和信息融合诊断结果进行比较,表明该模型和算法具有较高的诊断精度。

In order to improve the accuracy of elevator fault diagnosis, this paper puts forward a fault diagnosis algorithm using multi-information fusion technology. The fault diagnosis model of fuzzy information fusion is set up. At last, this model is used to diagnose elevator fault of driving system. The simulation of the fault phenomena has the good effect of this fault diagnosis system.
