CTCS-3-level train control center system

The invention provides a CTCS (China Train Control System)-3-level train control center system, comprising a TCC(Train Control Center). The TCC is used for carrier frequency and low frequency coded commands to a rail circuit device, and receiving rail section state information and device state information returned by the rail circuit device; the TCC is further used for transmitting coded information to the rail circuit device according to route information provided by a CBI (Channel Bus In), the rail section state information and the device state information, and the rail circuit device transmits movement authority information to the train according to the coded information; and the rail circuit device transmits a temporary speed restriction command to the train through an active transponder according to the temporary speed restriction command t transmitted by a TSRS (Temporary Speed Restriction Server). The rail circuit device is used for transmitting the movement authority information to the train according to the coded information. With the CTCS-3-level train control center system, the safety and the reliability of a high-speed railway train operation control system are both improved, and equipment cost and construction difficulty are both reduced.
