Description

technical field [0001] The invention belongs to an escape system, in particular to a high-rise building fire escape system. Background technique [0002] At present, "Do not use elevators in case of fire" can only use walking fire stairs to escape and wait for the rescue of firefighters. Or they will be trapped in the elevator, but in a more dangerous situation. Moreover, the elevator entrance leads directly to all floors of the building.

The fireworks are quickly drawn upwards, and people in the elevator will be choked by thick smoke and poisonous gas at any time and suffocate. "If a high-rise building fire can use an elevator to escape, it is undoubtedly the fastest and most effective way to reduce the casualty rate." At present, there are dual power supply elevators in the building, and the elevator cables and lighting cables are separated. In order to prevent the two power supply In the ...
