| description | The invention discloses a safe track circuit direction switching method and system. The method comprises the steps that according to a driving power source, the state of a direction relay is switched to a state that a normally-open contact is closed and a normally-closed contact is disconnected; and under the condition that the direction of the track section is the positive direction, the state of the direction relay is switched to the state that the normally-open contact is disconnected and the normally-closed contact is closed. The direction relay is arranged in the track circuit system, so that the direction relay can adapt to various coding application scenes, intervals and in-station track circuits, the direction relay is electrically connected to the track circuit system in a PCB wiring mode, and the fault guiding safety principle is considered in the design of a direction switching circuit; the state of the direction relay can be monitored by a track circuit system or obtained in a communication mode, |
