In view of the problems that rail transit signals are prone to error and distortion,the design of rail transit signal joint control system based on variable structure PID control is proposed.First,the rail transit signal joint control system is designed.The system is divided into traffic command and dispatching module,interlocking module,section blocking and train operation control module,and signal detection and monitoring module.Then,LTE technology is introduced into train-ground communication,To improve the safety and reliability of the system,a variable structure PID fuzzy neural network joint control algorithm for rail transit signal is proposed to realize rail transit signal control.Experimental results show that the proposed method has higher throughput and transmission success rate,and lower average end-to-end delay and bit error rate.
