With the development of urban economy, my country’s tall buildings are moving towards modernization, large-scale and multi-functional Due to the large and tall buildings, complex functions, and various equipment, once a fire occurs, it cannot be extinguished from the outside like ordinary buildings, which can easily cause major economic losses and casualties. Therefore, it is very important to grasp the characteristics of tall building fires.
First, fire cases in tall buildings
Second. Fire characteristics of tall buildings

Dense personnel, many combustibles, and difficult fire fighting

People and objects are highly concentrated. Once a fire occurs, the fire spreads quickly, It burns fiercely and produces a lot of toxic smoke, making it difficult to fight

When a fire occurs in a large space, it is difficult to evacuate people

The space passage is complicated, the vertical distance is long, evacuated to the ground or other safety The place is long

The fire spread rapidly, forming a three-dimensional fire

Large space buildings have large spans, many doors and windows, and good ventilation. Under the action of the airflow, a large area of ​​fire soon formed

Part of the steel structure is extremely easy to deform under high temperature, resulting in partial collapse of the building

After steel components are extremely susceptible to high temperature, they will Distortion and deformation occurred, which led to the collapse of the entire building and increased the difficulty of fighting.

Third: Smart Fire Fighting Solution:

1) Establish a set of “perception-evaluation-warning- Disposal-optimization & rdquo; fire prevention and control combined with intelligent iterative optimization and improvement of fire protection solutions, continue to improve the fire risk self-prevention and control capabilities of key fire protection units;
Perception: integrated monitoring of smoke, temperature and fire; remote visual supervision; mobile phone monitoring;
Assessment: regional fire risk assessment; single building fire risk assessment;
Early warning: early warning of fire area; early warning of unit area fire; emergency preparation plan to assist decision-making
Disposal: call the fire control center; management of fire-fighting duty personnel; fire-prevention monitoring management; fire-fighting system start-up management
Optimization: accident data analysis; fire protection publicity and education; fire protection supervision improvement; fire simulation drill

2) Use 5G Internet of Things information technology, fire technology, wisdom New technologies for firefighting achieve the seven goals of comprehensive perception, dynamic monitoring, intelligent early warning, unified command, rapid disposal, precise supervision, and data analysis, and effectively improve the fire prevention and control capabilities and actual command level of fire rescue agencies and key firefighting units themselves. Create a good fire safety environment for social and economic development, and escort the continuous stability of the society and the sustainable health of the people.
Comprehensive perception: Comprehensive perception of smoke, temperature, and fire
All-weather monitoring: HD camera 360° all-weather monitoring
Intelligent warning: fire control center warning; wireless terminal transmission warning; mobile terminal warning
Scientific command: Make scientific decisions through visual monitoring; initiate relevant emergency preparedness plans;
Quick disposal: emergency evacuation of personnel; activation of fire extinguishing system;
Precision supervision: precise fire area scope; division of risk areas to organize evacuation in an orderly manner;
Data analysis: risk assessment; simulation exercise
