为了满足高速列车提速和安全运行的需要,同时也为了满足不同线路分级运输的需要,我国在参照欧洲列车控制系统(ETCS)的基础上,制定了适合我国铁路运行情况的列车“大脑”——中国列车控制系统(CTCS)。CTCS系统有两个子系统,即车载子系统和地面子系统。车载子系统通过与地面子系统交换信息来控制列车运行。根据功能需要,可将我国列车控制系统划分为CTCS-0至CTCS-4五个等级。
In order to meet the needs of speeding and safe operation of high-speed trains, and also to meet the needs of different lines of classified transportation, China has formulated a train “brain ” that is suitable for the operation of China’s railways based on the European Train Control System (ETCS) China Train Control System (CTCS). CTCS system has two subsystems, namely vehicle subsystem and ground subsystem. Vehicle-mounted subsystems control train operation by exchanging information with ground-based subsystems. According to the functional requirements, our train control system can be divided into CTCS-0 to CTCS-4 five levels.
