A mechanical pressurization air supply mode or a natural ventilation mode is adopted during smoke prevention, so that smoke is prevented from entering an evacuation channel system; and a system for discharging smoke to the outside of the building by adopting a mechanical smoke discharging mode or a natural ventilation mode during smoke discharging.

The fire-fighting air valve is an important valve component in the system and directly determines the effect of smoke prevention and exhaust. Under normal conditions, the fire-fighting air valve is in a closed state, and when fire-fighting events and other situations need to be opened, the air valve is controlled to be opened through manual operation or an electric control actuator. Because the blast gate is in the closed state for a long time, can lead to the valve blade can't open or the range of opening is not enough because of corrosion, valve blade blocks or other unexpected troubles when needing to open, can't accomplish normal smoke prevention work, and the conventional open-close state monitoring to the fire control blast gate is all based on the operating condition judgement of blast gate executor, promptly through judging that the blast gate executor is in the running state then thinks the fire control blast gate and opens, but when the situation that the valve blade is not opened completely appears, the system monitoring thinks that the blast gate executor has run and judges the blast gate and open, but in essence can't satisfy normal smoke prevention demand because of the blade aperture is not enough, then can arouse serious fire control accident, the system also can't discover the trouble that the blast gate can't open completely simultaneously. In this regard, improvements are needed.
