High building intelligent escape system

Disclosed is a high building intelligent escape system. The high building intelligent escape system is divided into five portions of a seal door, a telescopic support frame, an escape descent control device, a life jacket and an intelligent control portion. The high building intelligent escape system runs through a whole wall. The seal door is used to seal two sides of the high building intelligent escape system at ordinary times, and achieves an indoor and outdoor isolation function. The telescopic support frame is fixed in the wall, can be automatically stretched out of the wall after the high building intelligent escape system is started, and can prevent an escaper from being scratched by the wall and a sill during the descending process. The escape descent control device is connected with the telescopic support frame, and the life jacket is fixed on the escape descent control device, and then the escaper only needs to wear the life jacket so as to successfully descend to the ground through the escape descent control device. The intelligent control portion is used to control opening and closing of the seal door, and can quickly roll up a rope of the escape descent control device after the escaper safely descends to the ground, and then the rope can be used by a next escaper. Power supply for the whole high building intelligent escape system is completed through a storage battery, and the whole high building intelligent escape system does not rely on a family power source.
