Abstract: Radio Dispatching Communication System for Urban Transit trains is with the purpose of transportation dispatching, to use the propagation of radio waves and implement communication between train and dispatching center or between trains. This article mainly focused on using VC++ programming technology to develop dispatching center operation interface, through the Socket network programming, and using wired mode to implement the communication simulation of train radio dispatching. At the same time, a brief introduce was given about related hardware and software part of train on-board display terminal.
