Train-to-Train Communication Technology for Train Control System in Urban Rail Transit
This study focuses on train-to-train(T2T)communication technology for train operation control systems.First,the basic principle of the train operation control system based on T2T communication and its key technologies are introduced.Second,the current mainstream T2T communication technologies based on logical point-to-point and physical point-to-point are investigated.Finally,the modeling and simulation calculation and analysis of T2T communication distance are conducted considering the typical operation scenario of T2T communication in urban rail transit;the simulation results show that the T2T direct communication distance in the non-tunnel area is approximately 765.8 m at 1.8 GHz and 923.6 m at 1.4 GHz in the non-tunnel area,while the direct communication distance is approximately 511.3 m at 1.8 GHz and 724.8 m at 1.4 GHz in the tunnel area.If the T2T distance exceeds this range,the logical point-to-point communication method should be used.This study aimed to provide a useful reference and theoretical basis for the design and application of T2T communication systems in next-generation urban rail transit.
