s1, when a fire disaster happens, the electromagnetic releaser releases the movable end of the smoke-blocking vertical wall main body under the power-off state, and the movable end of the smoke-blocking vertical wall rotates downwards around the rotating shaft to drop;

s2, when the electromagnetic releaser in the step S2 breaks down, the manual releaser acts, the movable end of the smoke barrier hanging wall main body rotates downwards around the rotating shaft to drop, and meanwhile, the alarm sends out alarm information;

s3, when the movable end of the main body of the smoke-blocking vertical wall rotates to the vertical state, the smoke-blocking vertical wall stops rotating;

and S4, restoring the smoke-blocking vertical wall to the initial position after the fire is over.

6. The method of claim 4 or 5, wherein in step S2, when the plurality of smoke barrier flaps rotate downward and fall, the first sealing member and/or the second sealing member fall to a vertical position and seal with the respective smoke barrier flaps and/or the wall to prevent smoke leakage.
