Rail transport in the country's economic development plays a decisive role in ensuring the safe operation of trains and improve transport efficiency has been the subject of rail transport, which requires high-performance train control system to support it. However, traditional cars to the track circuit as a way of communication has been unable to meet the modern requirements of the train control system. With the development of computer communications technology, the use of wireless communications transmission cars, high-capacity two-way information is rapidly train control system development, wireless occlusion Center (RBC) as a train control system for wireless communications core of the ground equipment of the railway system Run command and security plays a crucial role, research centers and car blocking wireless data transmission equipment on the train operation simulation system the process of data transmission and real-time security analysis have a significant role.
