CTCS-3-LEVEL TRAIN CONTROL CENTER SYSTEM

摘要

A CTCS (China Train Control System)-3-level train control center system comprises a train control center (101) and a rail circuit device (102). The train control center (101) is used for transmitting carrier frequency and low frequency coded commands to the rail circuit device (102), and receiving rail section state information and device state information returned by the rail circuit device (102). The train control center (101) is also used for transmitting coded information to the rail circuit device (102) according to route information provided by a computer based interlocking, the rail section state information and the device state information. The train control center (101) is further used for transmitting a temporary speed restriction command to the train through an active transponder according to the temporary speed restriction command transmitted by a temporary speed restriction server. The rail circuit device (102) is used for transmitting the movement authority information to the train according to the coded information. The CTCS-3-level train control center system is used for improving the safety and the reliability of a high-speed railway train operation control system, and reducing equipment cost and construction difficulty.
