The invention relates to the technical field of rail transit, and discloses a train safety protection method, which comprises the following steps: when both LTE and radar communication channels are interrupted, an OC system detects that the communication with a train is interrupted and automatically generates a protection area according to the position of the train before the communication is interrupted; when the LTE and radar communication channel is normal, the OC system communicates with the train to obtain the real-time train position, and the automatic protection areas are sequentially cancelled according to the pressure occupying information provided by the radar; the occupation information is that the driving resource is only allowed to be occupied by one train at the same time, and the train can operate the turnout resource managed by the associated OC system. According to the method, it is ensured that the train can still safely and automatically run when communication is interrupted, the train safety boundary is dynamically generated through the radar technology to maintain the safety tracking interval of the front train and the rear train, manual intervention is avoided, the operation efficiency and safety are improved, meanwhile, the ground facility requirement is simplified, and the construction and maintenance cost is reduced.
本发明涉及轨道交通技术领域,公开了一种列车安全防护方法,包括:当LTE和雷达通信通道均中断时,OC系统检测到与列车通信中断并根据通信中断前的列车位置自动生成防护区;当LTE和雷达通信通道正常时,OC系统与列车通信获取实时列车位置,并根据雷达提供的占压信息依次取消自动防护区;所述占压信息为同一时间内,行车资源仅允许被一列车占用,且该列车可操作其关联的OC系统管理的道岔资源。本发明确保了列车在通信中断时仍能安全、自动运行,并通过雷达技术动态生成列车安全边界以维持前后车的安全追踪间隔,避免了人工介入,提高了运营效率和安全性,同时简化了地面设施需求,降低了建设和维护成本。
