Second step, judge whether train needs normal power supply, keep if not current state; If closure is waken button up, logic relay first signal input end is obtained electric, logic relay current output terminal starts output current, and train power supply contactor obtains electric, goes to the 3rd step;
The 3rd step, judge that accumulator has or not output voltage, go to the 4th step if having; If closed accumulator protecting switch of nothing, obtains logic relay secondary signal input end electric, logic relay current output terminal stops output current, and train power supply contactor dead electricity goes to the 4th step;
The 4th step, judge that whether accumulator is under-voltage, go to if not the 5th step; If closed accumulator under-voltage protection second switch, obtains logic relay the 3rd signal input part electric, logic relay current output terminal stops output current, and train power supply contactor dead electricity goes to the 5th step;
The 5th step, in the time of the equal dead electricity of cab key switch relay at train two ends, judge that whether train needs power-off to enter sleep state, goes to the 6th step if not; If closed sleep button, obtains logic relay the 4th signal input part electric, logic relay current output terminal stops output current, and train power supply contactor dead electricity goes to the 6th step;
The 6th step, judge whether to finish logic control, go to if not second step, if logic control finishes.
The method adopts logic relay under different situations, to wake up vehicle or to sleep, and it is little to take up room.
The present invention further perfect technical scheme is as follows:
Preferably, in the first step, the positive terminal of logic relay is connected with positive bus-bar through protective breaker.
Preferably, in the first step, this cab key switch relay contact, another cab key switch relay contact disconnect respectively in the time that this cab key switch, another cab key switch are connected under corresponding relay obtains the suction of electric generation.
What the present invention can effectively realize vehicle wakes/sleeps control up, and equipment needed thereby takes up room little.
