The invention relates to a crossing control method for an urban rail transit. The method comprises the steps of 1) when a train is close to a crossing, an ATS subsystem sending a setup instruction of entering a path through the crossing to a CI subsystem; 2) after the crossing occupied by the train is judged to be close to a section and the condition that a delay timer counts to zero, sending a train approaching message; 3) closing a road annunciator, meanwhile prompting a crossing terminal to close a rail, and lowering the rail after the crossing terminal confirms that the crossing is clear; 4) lowering the rail and sending a closing message to the CI subsystem; 5) automatically starting a crossing protection annunciator; 6) authorizing the train to pass the crossing after an opening message from the crossing protection annunciator; 7) after the train passes the crossing, removing the train approaching message and sending to the crossing control subsystem; and 8) lifting the rail. Compared with the prior art, the crossing control method for the urban rail transit has the advantages of precisely locating the position of the approaching triggering informing point, optimizing the crossing occupation time of the rail transit train, automatically managing the crossing informing messages and the like. |
