The present invention relates to an alarm system for an undetected ground signal in an automatic train operation system. More specifically, the alarm system comprises: a speed generator (10) providing a signal for detecting a moving distance of a train; a moving distance detection means (20) detecting a real-time moving distance of the train through the speed generator (10); an automatic operation system (30) providing station-to-station distance information (D2) operated by the train and a detection signal (S1) of a ground signal device (60); a main controller (40) determining whether the train has passed the ground signal device (60) in an undetected manner, based on the information provided from the moving distance detection means (20) and the automatic operation system (30); and a notification means (50) controlled by the main controller (40). Therefore, when a ground signal transmitted from the ground signal device is not detected during automatic operation of the train, the alarm system of the present invention gives a warning so that an engineer of the train immediately acknowledges the undetected ground signal, thereby preventing overrun or various accidents caused thereby. |
