Problems solved by technology

The reason is that when a fire occurs in life, the stairs are the main passage for safe escape. The existing fire-fighting equipment in the stairwell does not have smoke removal equipment, and the smoke cannot be removed in time, which will easily lead to toxic and harmful smoke in the stairwell. The air cannot circulate, and people will be suffocated to death in the building after a long time

Embodiment 1

[0055] refer to figure 1 , is a smoke removal and fire prevention stairwell control system disclosed by the present invention, the stairwell includes an upper staircase 1, a lower staircase 11, a platform 12 arranged between the upper staircase 1 and the lower staircase 11, a wall 14 and a fire door 15. There is a stair handrail 13 at the middle of the upper staircase 1 and the lower staircase 11. The wall body 14 is coated with a fireproof layer, and the fire door 15 is rotatably connected to the wall body 14 through hinges. The fire door 15 and the fire wall body 14 can effectively prevent the further spread of the fire.

[0056] refer to figure 1 A fire hydrant 16 is arranged on the wall 14 and above the platform 12 , and the fire hydrant 16 is arranged at the end of the wall 14 away from the fire door 15 . The top of the fire door 15 is provided with a safety exit indicator light, which can be convenient for guiding safe passage, and the safety exit indicator light is co...

Embodiment 2

[0069] A kind of smoke removal and fire prevention and fire fighting stairwell control method based on the smoke removal and fire prevention and fire fighting stairwell control system in embodiment 1, refer to image 3 , including fire emergency lighting control method A, which includes:

[0070] S101. Real-time detection of whether there are people in the stairwell through the human body detection module 31;

[0071] S102. When the corresponding human body detection module 31 detects that there is no person, the controller 2 controls the fire emergency lighting device 3 to turn off after a set time delay.

[0072] When the human body detection module 31 detects that there is someone in the stairwell, and the light detection module 32 detects that the light in the stairwell is dark, the fire emergency lighting device 3 starts, and when the human body detection module 31 detects that there is no one in the stairwell, The fire emergency lighting device 3 is turned off after del...

Abstract

The invention relates to the technical field of fire-fighting, in particular to a control system and method of smoke-removing fireproof fire-fighting staircase. The staircase comprises upper stairs, lower stairs, a wall and a fireproof door, wherein the wall is coated with fireproof layers, and a fire hydrant is arranged on the wall and located above a platform; and the input end of a controller is connected with a smoke alarm, the smoke alarm is arranged on the wall and used for detecting the concentration of smoke in the staircase, and the controller is connected with a smoke exhauster whichis used for exhausting smoke in the staircase. When a fire disaster occurs, people can escape to the staircase for escape, and the fireproof door and the fireproof wall can effectively prevent further spreading of the fire behavior; and when the smoke alarm in the staircase detects that the concentration of the smoke in the staircase exceeds a set value, the smoke alarm sends a signal to the controller and gives an alarm, and meanwhile, the controller controls the smoke exhauster to be started to exhaust the smoke out of the staircase so that the situation that air cannot circulate due to much smoke in the staircase can be avoided, and it can be effectively guaranteed that people can escape safely.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a control system and method for smoke and fire prevention stairwell control. Background technique [0002] There are more and more modern high-rise buildings, and fire fighting in high-rise buildings is an international problem. Whether it is escape or fire rescue, it is very difficult. According to statistics, most of the people who were burned to death actually died of asphyxiation due to inhalation of toxic gases. When a fire breaks out in a high-rise building, stairs are the main passage for safe escape. [0003] Stairwell refers to a space occupied by stairs, which can be divided into open stairwell, closed stairwell and smoke-proof stairwell. It was built because of the actual needs of life, as a hub connecting up and down traffic. [0004] At present, fires occur frequently at home and abroad, especially when high-rise buildings are on fire, rescue difficulties ...
