The Train Operation Safety Warning System employs environmental perception devices such as radar and cameras. Based on advanced space-time synchronization technology, it achieves real-time perception of the environment within a certain range ahead of the running train through deep fusion of multi-sensor information and artificial intelligence detection algorithms. The system supports active identification of sudden intrusions on the track or falling obstacles from tunnel structural equipment, accurately detects obstacles and their danger levels within the train clearance envelope, and outputs warning information externally when train operation safety is affected.
