At present,the proposed urban rail transit information transmission system has poor stability,resulting in high packet loss rate.A new urban rail transit information transmission system is designed based on 5 Gwireless communication technology.The system framework is constructed by using automatic train monitoring system,regional control system,on-board control system,interlocking control system,database storage system and data communication subsystem.The hardware monitoring subsystem,controller and 5 Gwireless data communication subsystem are designed to ensure the information transmission and instant communication of urban rail transit.The application program is divided into client and server by socket.After receiving the connection request from client,the server returns the response message to the client to realize the software communication function.At the same time,the communication signal loss analysis program is designed.In order to verify the effect of the system,comparative experiments are set up.The results show that the urban rail transit information transmission system based on 5 Gwireless communication technology can effectively ensure the stability of the transmission process,reduce the packet loss rate in the communication process,and has good transmission security.
