The invention relates to the field of
machine learning, and discloses a charging
pile fault diagnosis method, which comprises the following steps: S1, preparing an environment, building a
deep learning development environment, and providing a necessary technical environment for the training and deployment of a subsequent model; and S2,
data acquisition and
processing: installing a
current sensor, a
voltage sensor and a temperature sensor on a
new energy automobile charging detection vehicle, and acquiring operation data of the charging
pile in real time. And S3, model definition: a fault diagnosis model based on
deep learning is constructed, a fully connected neural network (DNN) is adopted, and the model comprises an input layer, a
hidden layer and an output layer. The key operation data of the charging
pile are collected in real time through the sensor, the fault state is intelligently judged in combination with the
deep learning model, rapid and accurate fault positioning and diagnosis are achieved, and the maintenance efficiency of the charging pile is remarkably improved. The
system can automatically extract data features and analyze fault types, and manual intervention is reduced.
