The invention relates to an urban rail transit clouded full-automatic operation signal system based on a 5G technology, and belongs to the field of rail transit. According to the invention, embedded special equipment is replaced by the station cloud server; the central ATS and the station ATS both run on the cloud server; system functions are redistributed, ZC and CI functions in an existing FAO signal system are combined to form a ZCI subsystem, and vehicle running speed limit calculation and speed limit monitoring functions are transferred from vehicle-mounted equipment to ground ZCI; a DCS subsystem of an urban rail transit full-automatic operation signal system based on 5G is adopted; a VC subsystem is designed, so that vehicle-mounted action execution and state acquisition are realized; under the condition of emergency braking of the vehicle, the scheme that the ground subsystem directly generates the speed limit of 25 km/h and directly commands the VC to operate is adopted, and emergency rescue under the fault condition is achieved. The equipment concentration degree is higher; the train-ground communication delay is greatly reduced, and the control is more reliable; and the fault response capability is greatly improved.
本发明涉及一种基于5G技术的城市轨道交通云化全自动运行信号系统,属于轨道交通领域。本发明通过车站云服务器替代了嵌入式专用设备;中心ATS和车站ATS均运行于云服务器;对系统功能进行了重新分配,将现有FAO信号系统中的ZC和CI功能合并,形成ZCI子系统,并将车辆运行的限速计算,限速监控功能从车载设备转移到地面ZCI;采用了基于5G的城市轨道交通全自动运行信号系统的DCS子系统;设计了VC子系统,实现了车载的动作执行和状态采集;在车辆紧急制动的情况下,通过地面子系统直接生成25km/h的限速,并直接命令VC运行的方案,实现了故障情况下的应急救援。本发明设备集中度更高;大大降低了车地通信延时,控制更加可靠;大大提高了故障的响应能力。
