Among them, how to deliver the massive real-time data that reflex the status of the driving train to the monitoring center on the groundfor processing, to realize wireless data transmissionbetween the train and the ground, thereby achieve the purpose of safe running, is a difficult problem and one of the key technologies of the system, international research in the field has just been unfolding. Research on the train safety monitoring wireless datatransmission system that adapts to the development of railway and synthesizes munications technologies is the core problem of the munication. By investigating and consulting the massive project example bined with munications technology,the author has done the detailed research and the discussion to the train safety monitoring wirelessdatatransmission at municationbetween real-time data monitored for train and themonitoring center on the ground, the thesis pares with and demonstrates
