Zusammenfassung:The invention discloses an elevator car guide shoe fault diagnosis method. The method includes the steps that sensor devices are installed; known vibration signals of elevator guide shoe fault free, an upper left guide shoe fault, an upper right guide shoe fault, a lower left guide shoe fault and a lower right guide shoe fault are obtained; energy threshold decomposition is conducted; effective identification indexes of all the signals are calculated; the signals with effective identification less than 0.5 are regarded as invalid signals; kurtosis coefficients, peak-peak values, energy coefficients and steepness coefficients of all the effective signals are calculated to form a fault feature set; and the fault feature set is used for studying a deep network model to obtain a state prediction model. According to the elevator car guide shoe fault diagnosis method, the fault position can be quickly and accurately located, and the detection efficiency is improved. 本发明公开了一种电梯轿厢导靴故障诊断方法。方法为:安装传感器装置;获取已知的电梯导靴无故障/上左导
