The invention discloses a train timetable display method and device based on a train operation monitoring system. The method helps a driver to monitor train operation, current time state, station information, departing time, arrival time, advancing and delaying information and the like can be known through a human-machine interface in real time, so that a train attendant monitors train operation state in real time, current station and next station information of the train can be visually known, and labor intensity of the train attendant is relieved. The technical scheme includes that current position of the train is acquired by the aid of the train operation monitoring system, stations on an operating route of the train are positioned, the positioned stations on the operating route of the train are matched with stations in a pre-stored timetable data file, and a train operating timetable is displayed based on station information corresponding to the matched stations. The method judges whether the train arrives in advance/on the stroke/behind schedule or not based on system time of the train operation monitoring system when the train arrives the station or passes the station and the matched station information.
