Abstract: This paper mainly studies the problems of anomaly detection and trend prediction in intelligent operation and maintenance. Gaussian filter, normalization processing and other methods are used to complete the preprocessing of the data; use the Hampel filter function to obtain abnormal values, calculate the abnormal cycle through fast Fourier transform, and finally use the data training model and decision tree classifier to establish The rolling prediction model based on BP neural network realizes the requirements of abnormal prediction and trend prediction.
