[0019] It can be explained that during the operation of railway equipment, it will be affected by vibration, electromagnetism and the external environment, resulting in filtered excitation peaks and abnormal data in the received equipment monitoring data.

[0021] It can be explained that, depending on the type of monitoring equipment, when there is no external control input, the monitoring data conforms to the one-dimensional Kalman filter model, in which the A matrix is ​​equal to the transpose of the A matrix, B is a zero matrix, and H is a matrix whose elements are all 1. The Kalman filter algorithm can effectively filter out the influence of excitation peaks and abnormal data, so that the data remains smooth and stable.

[0023] It can be explained that, by training the railway equipment operation and maintenance historical data samples based on the BP neural network algorithm, the back-propagation error signal is used to adjust the weights and bias characteristics in the network, and the forward propagation and back-propagation processes are repeated until the preset training rounds are reached or the error is less than a certain threshold, thereby reducing the output error and optimizing the network performance, thereby making the predicted values ​​of railway equipment operation in different environments more accurate, and solving the problem of difficulty in accurately setting weight values.
