Automatic train control system

The invention provides an automatic train control system. The automatic train control system comprises a ZC subsystem, a CI subsystem and CI execution units; the ZC subsystem is in communication connection with the plurality of CI subsystems, and the CI subsystems are in communication connection with the plurality of CI execution units through a backbone network of an ATC system; the ZC subsystem and the CI subsystem are arranged in a main/standby control center; the CI execution units are arranged in a station, are in communication connection with trackside equipment and controls the trackside equipment. According to the automatic train control system, the number of hardware can be effectively reduced, compared with the prior art, the workload of station maintenance personnel is remarkably reduced, and the manpower maintenance cost is reduced. 本发明提供一种列车自动控制系统，包括：区域控制器ZC子系统、计算机联锁CI子系统以及CI执行单元；所述ZC子系统与多个CI子系统通信连接，所述CI子系统与多个CI执行单元通过ATC系统的骨干网通信连接；其中，所述ZC子系统与所述CI子系统设置在主备控制中心内；所述CI执行单元设置在车站内，与轨旁设备通信连接并控制所述轨旁设备。本发明
