In recent years, with the increasing scale of road traffic construction in my country, as of the end of 2019, the scale of tunnels in my country It has reached 18.9666 million meters and 19,967. At present, my country has become the country with the largest number of tunnels in the world, the most complex conditions, and the fastest technological development. The danger of tunnel fire accidents caused by vehicle failures, collisions, spontaneous combustion and other reasons in the tunnel is obviously increasing. There have been many deaths and injuries in tunnel fire accidents at home and abroad.
First, tunnel fire hazards
Case
Second , Causes of fire in highway tunnels
　　 (1) Fire caused by the failure of the vehicle itself
　　 (2) A vehicle accident caught fire.
　　 (3) Flammable materials on the vehicle cause a fire.
　　 (4) Fire caused by the tunnel itself.
　　 (5) Man-made destruction. Including arson, smoking, terrorist attacks, etc.

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 promotion of fire protection solutions, continue to improve the fire risk self-prevention and control capabilities of key fire departments;
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
