Urban road tunnels, due to their enclosed space, limited external entrances and exits, and dense traffic, have a higher frequency of fires. Moreover, after a fire occurs, the temperature and smoke in the tunnel rapidly accumulate, making on-site evacuation and rescue operations very difficult. This patented technology (a dynamic feedback-based intelligent evacuation and rescue system for tunnel fires based on digital technology, patent number: L201110007498.0) discloses a dynamic feedback-based intelligent evacuation and rescue system for tunnel fires based on digital technology, which includes a fire situation information acquisition subsystem that analyzes and processes the temperature data collected by fire detection instruments to obtain fire situation information; a three-dimensional temperature and smoke field reconstruction subsystem that establishes a three-dimensional temperature and smoke field information based on the temperature data and fire situation information; and an emergency evacuation and rescue decision subsystem. Analyze and evaluate the development trend of a fire based on real-time information provided by the Fire Situation Information Acquisition Subsystem and the Three-Dimensional Temperature Smoke Field Reconstruction Subsystem, and dynamically adjust the evacuation and rescue plan. The Digital Virtual Reality Display Subsystem, based on digital virtual reality technology, virtually displays the fire situation information and temperature smoke field inside the tunnel in dynamic form, and supports real-time roaming through the fire tunnel. This invention helps in the scientific decision-making for tunnel fire rescue, overcoming many deficiencies of existing tunnel fire plans such as rigidity, framework, poor real-time performance, and adaptability.
