Summary: | The invention relates to a method and system for a train to autonomously identify the state of a signal in front of the train, and is applied to Incremental Train Control System (ITCS). The method comprises the following steps: (S1) enabling a train-mounted computer to download a digital track map, and enabling navigation satellite positioning equipment of the train to obtain real-time latitude and longitude coordinates of the train; (S2) enabling the train-mounted computer to obtain block section occupancy information of the train by virtue of a map matching method according to the digital track map and the latitude and longitude coordinates of the train, and updating the digital track map; (S3) enabling a train-mounted radio station to send the block section occupancy information to a wireless block center; and (S4) enabling the wireless block center to send state information of the virtual signal, which is closest to the front end of a locomotive on a running route of the train andby which the train has no |
