A transmission delay control method of railway communication networks based on a neural network is studied.This study uses the communication network delay data captured by TCN network analyzer to serve as data samples.With the data samples as input,the prediction of transmission delays of railway communication networks is realized by using the neural network.With the prediction results as the output,combined with PID,the delay control quantity and delay compensation quantity are obtained to realize the transmission delay control of railway communication networks.The results show that the new control method in this paper reduces the delay time and increases the communication link rate as compared with the control method based on power control protocol and the control method based on delay compensation,which proves the effectiveness of this new method.
