The invention relates to a method for early warning of a conflict between subway trains. The method comprises the following steps: firstly, generating a topological structure chart of a rail traffic network according to planned running parameters of each train; then on the basis of the topological structure chart, analyzing the controllability and the sensibility of a train flow; then generating conflict-free running tracks of a plurality of trains according to the planned running parameters of each train; then at each sampling moment, on the basis of current running states and historical position observing sequences of the trains, forecasting advancing positions of the trains at some moment in the future, establishing an observer for the logic of a continuous dynamic state to a discrete conflict state of the trains, and mapping the continuous dynamics into conflict states expressed by discrete observation values; and when a system has the possibility of violating traffic control rules, dynamic mixed behaviors of a mixed subway traffic system are monitored, and warning information is provided for a control center. Through the adoption of the method disclosed by the invention, the tracks of the subway trains can be cyclically forecast in real time and train conflict early warning can be given effectively, so that the safety of subway traffic is improved.
