A method for waking up a train which in four carriages coupling mode from sleep state on double-track-line, the double-track-line comprising a track A and a track B, the track B comprising a track B1 and a track B2 on each of which a train in four carriages coupling mode can be parked, wherein the method comprises steps of:
- receiving a static test request transmitted by a train in four carriages coupling mode on the track B1 or the track B2, determining whether a test environment of the train satisfies a static test condition, and transmitting a static test permission instruction to the train so that the train performs a static test if the test environment of the train satisfies the static test condition;
- receiving a dynamic test request transmitted by the train when the train has completed the static test, determining whether a test environment of the train satisfies a dynamic test condition, and transmitting a dynamic test permission instruction to the train so that the train performs a dynamic test if the test environment of the train satisfies the dynamic test condition;
- and
- receiving information, indicating that the train can be woken up, transmitted by the train when the train has completed the dynamic test, and controlling the train to wake up from sleep state.
