The invention discloses an elevator drive host fault diagnosis method. The method comprises the steps of collecting first working information of a plurality of normal motors, second working information of a plurality of fault motors and third working information of a to-be-recognized motor; processing and training the plurality of pieces of first working information to obtain a first neural network model; conducting optimization training on the first neural network model based on the second working information to obtain a fault recognition model; and processing the third working information, and inputting the processed third working information into the fault recognition model to obtain a motor diagnosis result. The invention further discloses an elevator drive host fault diagnosis device and a readable storage medium. The fault type of the motor can be recognized, and safe and stable operation of the motor can be ensured. The fault type of the motor can be judged according to the motor diagnosis result, wherein the fault type of the motor can be a mechanical system fault or an electromagnetic system demagnetization fault.

    本发明公开了一种电梯驱动主机故障诊断方法,该方法包括:采集若干个正常电机的第一工作信息、若干个故障电机的第二工作信息以及待识别电机的第三工作信息;对若干个第一工作信息进行处理和训练得到第一神经网络模型;基于第二工作信息对第一神经网络模型进行优化训练,得到故障识别模型;对第三工作信息进行处理,并将处理后的第三工作信息输入到故障识别模型中,得到电机诊断结果。本发明还公开了一种电梯驱动主机故障诊断装置和一种可读存储介质。本发明能够识别出电机的故障类型,能够保证电机安全稳定地运行。通过电机诊断结果可以判断电机的故障类型,其中电机的故障类型可以是机械系统故障或者是电磁系统退磁故障。
