Large high-rise building indoor fire urgent evacuation indication escape method and system

Abstract

The invention discloses a large high-rise building indoor fire urgent evacuation indication escape method and system, and belongs to the field of high-rise building fire safety. The large high-rise building indoor fire urgent evacuation indication escape method comprises the following steps: step 1, a fire source is located; step 2, a dynamic module of fire spread is set up; step 3, according to the dynamic module of fire spread in combination with the structural information of a building, the spatial position of an ignition point and the spatial position of fire-fighting equipment in a large high-rise building are determined, predictions are made over fire spread paths, and evacuation escape routes are planned; step 4, according to the designed escape routes, site equipment is controlled in a selective mode for assisting people in evacuation. According to the large high-rise building indoor fire urgent evacuation indication escape method and system, the fire control escape routes are made based on specific fire behavior, so that evacuation time is shortened; the existing problems that when a fire breaks out, a fire control evacuation escape way is crowded , low in efficiency and disorderly and stampedes easily occur are solved fundamentally; the practical significance of improving the safe evacuation performance of the large high-rise building and reducing the property loss and casualties caused by the fire in the large high-rise building is quite high.

Description

technical field [0001] The invention belongs to the field of high-rise building fire safety, and relates to a large-scale high-rise building indoor fire emergency evacuation instruction escape method and system. Background technique [0002] In recent years, with the deepening of China's urbanization process, large-scale high-rise buildings continue to emerge, and the resulting fire hazards have also increased, and the probability of fire occurrence has also increased. Due to the special requirements of equipment, facilities, decoration and other aspects of large high-rise buildings, the fire load is greatly increased. Once electrical, smoking, and fire are used carelessly, fires can easily occur, causing a lot of property losses and casualties, and forming adverse social impacts. Therefore, people pay more and more attention to the fire safety of large high-rise buildings and the safe evacuation under fire conditions. [0003] Compared with other buildings, large-scale hi...

AI Technical Summary

Problems solved by technology

[0003] Compared with other buildings, large-scale high-rise buildings have the following characteristics. First, there are many floors and a long vertical distance, and the time to evacuate to the ground or other safe places will be longer. Due to the general herd mentality and panic psychology in the crowd during the evacuation process, they often evacuate to familiar and bright routes, which increases the difficulty of evacuation; And the smoke spreads upward quickly, increasing the difficulty of evacuation

[0004] At present, the working height of domestic fire rescue vehicles is limited, and the fire fighting of large-scale high-rise buildings is mainly based on their own fire-fighting equipment for self-rescue. Due to height restrictions, evacuation and rescue are extremely difficult

At the same time, the current escape in the building only stays on the independent emergency evacuation sign light. The design process is simple, and the mechanical design is in accordance with the specifications and standards. Fire evacuation escape route plan
