A novel GSM-R train control system and method for real-time transmission of data

摘要

In this paper, we propose a novel GSM-R (GSM for Railway) train control system and method for real-time transmission of data. It includes distributed antenna array, BTS(Base Transceiver Station) in the network side and train locomotive terminal; Distributed antenna array set up along the railway, providing the same fixed frequency signal for the train locomotive terminal in order to make data transmission link based on the circuit domain always connect. A special BTS in the network side connects with distributed antenna array in the cable way, controlling the open or shut state of antenna based on the handover criterion so that the network side realizes handover function. Train locomotive terminal connects with the BTS through wireless transmission link. The system changes the current GSM-R handover scheme and makes the train running in the fixed frequency; a special BTS in the network side decides handover function, which eliminates the ping-pong handover phenomenon and enhances the communication stability and safety credibility of the train significantly. Finally, we'll simulate the performance of the system by using MATLAB. The result shows that the outage rate of handover under this new scheme is obviously smaller than the current scheme, thus higher probability of successful handover is achieved.
