[0039] image 3 It is a flowchart of a method for evaluating device status in the second embodiment of the present invention. This embodiment is optimized on the basis of the foregoing embodiment, and gives a detailed introduction to the training process of the prediction model. For details not described in this embodiment, please refer to the above embodiment. See image 3 , The device state evaluation method provided in this embodiment may include:
[0040] S210. Use the historical data of the device with the normal state label and the abnormal state label added as training data, train the model constructed based on the conditional variational autoencoder to obtain a prediction model, and store the prediction model in the model center.
[0041] Specifically, before predicting the equipment state data through the predictive model, the predictive model needs to be trained. First obtain the historical device data stored in the database. Since the device histori...
