Pavement covering identification method and device based on peak value and phase detection

The invention discloses a pavement covering identification method and device based on peak value and phase detection. The method comprises a sensitive capacitor signal acquisition stage; a feature extraction stage; a neural network classification stage: constructing a narrow neural network model, and training the narrow neural network model through the data set; and classifying and outputting the coverings. The sensitive capacitance peak value and phase difference combined intelligent classification prediction algorithm can provide data information of more dimensions. The combination analysis of the multi-dimensional data can improve the classification accuracy of the pavement coverings. Compared with a traditional method for detecting a single data source of the charging and discharging waveform, the method can more comprehensively know the road condition by combining multiple features, and improves the accuracy of identifying different coverings. An intelligent classification prediction algorithm is introdu
