A Low Cost Real-Time Communication System of Locomotive Based on GPS

In this paper we propose a mobile communication solution of real-time operating data for moving locomotive without the railway GSM (GSM-R).The method exploits a low cost communication system based on GPS. Through the existed train dispatching radio communication system (TDRCS) and the railway packet switched network (RPSN), the real-time operating data which transacted by data-voice synchronous wireless dispatching communication subsystem can transmit to the ground data processing subsystem,and then the real-time data can be shared by other local railroadpsilas dispatching centers,stations along the railroad, railway branch locomotive depots and other railway units.The system have the advantage of low cost and easy to achieve.
