Abstract

Aiming at the problems existing in the fire control system of highway tunnels, such as single detection objects, lagging information transmission, and low intelligent level of fire handling, a three-dimensional digital twin model and multi-sensor fusion positioning were constructed based on the theory of fire causes and characteristics and digital twin technology theory. Based on the Unity platform, we designed a fire linkage control system based on digital twins and established a BIM model for tunnels and a visualization simulation platform. Experiments show that this model significantly improves the speed of fire emergency response and the level of digital management, as well as the technical level of safe operation in tunnels.
