Tunnel ventilation and smoke exhaust and personnel evacuation collaborative control method and device, equipment and medium

Abstract

This application provides a method, device, equipment, and medium for coordinated control of tunnel ventilation and smoke extraction and personnel evacuation, belonging to the field of tunnel fire safety technology. The method includes: acquiring multi-source information within the tunnel; determining the situation information corresponding to each multi-source information based on the multi-source information and preset situation evolution rules; dynamically generating optimal evacuation paths for personnel at different locations based on the situation information; determining the control strategy for tunnel ventilation and smoke extraction based on the fire development trend and the availability of evacuation routes; dynamically updating the control strategy according to the personnel evacuation trend and determining the updated airflow; and continuously monitoring personnel evacuation and smoke diffusion status during the dynamic updating of the control strategy to update the airflow accordingly. The method, device, equipment, and medium for coordinated control of tunnel ventilation and smoke extraction and personnel evacuation provided in this application can improve the accuracy of disaster prediction and the synergy of control in tunnel fire emergency response.
