Train operation protection method and device

The invention provides a train operation protection method and device. According to the train operation protection method and device, the state feedback signal of a train automatic protection system are obtained; whether the train automatic protection system is in a failure state or not is judged according to the state feedback signals of the train automatic protection system; when the train automatic protection system is in the failure state, a failure prompt signal is generated and displayed; the current running speed of a train is obtained and compared with the highest limit speed; and whenthe current running speed of the train is greater than the highest limit speed, a traction removal instruction is sent to a traction converter so as to control the traction converter to stop traction. Thus, the faults of the train automatic protection system can be found in time through the state feedback signals; the running speed of the train is monitored when the train automatic protection system breaks down; traction
