The invention relates to a braking control device, in particular, a braking control device for a high-rise fire rescue system.
At present, with the influx of people to the big cities, the urban environment seems more and more crowded, coupled with the scarcity of urban land resources, so the new buildings are getting taller and taller to ease the pressure of the city. However, with this comes a series of safety issues such as fire escape. In case of a fire on the ground floor, people on the upper floors can only continue to go up to the top of the building to escape. As the buildings are now very high, fire engines have been unable to put out fires on the upper floors, relying only on the floor's own firefighting facilities if they can not put out the fire, it is likely to make the fire more and more to the upper floors, and finally endanger the people who escape on the roof.
Now some floors less buildings equipped with escape rope, the human body in the rope ring, and then their own control of the speed of decentralization, from the roof down to the ground, this method is suitable for about ten floors of the building, but for twenty or thirty floors of the office building or residential, the person from the roof with rope tied down, it is clear that the health and safety of escapees are a challenge. In addition, for the elderly, infirm and people with fear of heights, even on the lower floor with rope escape is very unsafe.
After searching, patent number CN201811248241.2, patent name “A KIND OF HIGH-RISE FIRE RESCUE DEVICE” invention patent discloses the fire rescue device installed in the roof of a high-rise building, including a lift control host, A lifeboat and B lifeboat.
