When the storage battery is in dormancy, the automatic awakening device 1 controls the third coil R3 to be powered through the second output end of the automatic awakening device, at the moment, the third normally closed contact R31 is disconnected, the loop formed by the second normally open contact R21, the third normally closed contact R31 and the second coil R2 is disconnected, the second coil R2 is powered off, the corresponding contactor K and the second normally open contact R21 are disconnected, the storage battery stops supplying power to the electric equipment, and the storage battery completes the dormancy.

When the pantograph is not lowered or the main circuit breaker is not opened, one of the sixth normally-closed contact R61 and the seventh normally-closed contact R71 is not closed, and the storage battery cannot complete the sleep.
It is thus clear that providing two conditions for the dormancy of train through this embodiment, make the battery only satisfy the pantograph when descending and main circuit breaker disconnection at the train, just can accomplish the dormancy, guaranteed the reliability of train dormancy, improved the security of train.

And when a fire disaster happens in the train, the eighth normally closed contact R81 is not closed, and the storage battery cannot complete dormancy at the moment, so that the situation that the storage battery is dormant when the fire disaster happens in the train, the power-off of electric equipment on the train is caused, and the function of alarming or detecting the fire disaster on the train cannot be completed is avoided.
Therefore, a condition is provided for the dormancy of the train through the embodiment, so that the dormancy of the storage battery can be completed only when the train meets the condition that a fire disaster does not happen, the reliability of the train dormancy is guaranteed, and the safety of the train is improved.
