The invention discloses a voiceprint-based power transformation equipment
anomaly detection method and device, relates to the field of power transformation
equipment monitoring, and can solve the technical problem of low accuracy of existing voiceprint-based power transformation equipment
anomaly detection. The voiceprint-based power transformation equipment
anomaly detection method comprises the steps of obtaining historical voiceprint
feature data of a plurality of power transformation equipment, and based on a two-dimensional convolutional network, obtaining a plurality of historical voiceprint
feature data of the plurality of power transformation equipment; extracting a local time-frequency feature of the historical voiceprint
feature data to obtain a first voiceprint feature; performing
feature extraction on the first voiceprint
feature based on a bidirectional
recurrent neural network to obtain a second voiceprint feature; according to the second voiceprint feature, multiple times of iterative training is carried out on a preset initial voiceprint detection model, joint optimization is carried out on
model parameters based on comparative learning and
perceptron classification during iteration, training is completed until the
model parameters meet preset values, and a voiceprint detection model is obtained; and obtaining real-time voiceprint features of the to-be-detected power transformation equipment, and inputting the real-time voiceprint features into the voiceprint detection model to obtain an anomaly detection result of the to-be-detected power transformation equipment.
