Abstract

A wavelet analysis method using DTS for space-time temperature field of tunnel fire is developed in this paper

and the algorithm for tunnel fire alarm is proposed.Two cases of fire simulation experiments in a tunnel were performed for temperature field to be monitored in real time.One is with a low-speed wind and the other is with a high-speed wind.According to the space-time matrix obtained in both cases

the development behavior of tunnel temperature field in fire is then analyzed.The wavelet base Ribo 3.7 is selected to successfully identify the singular point of the temperature field of the tunnel in fire.The test results show that locating singular point of tunnel space-time temperature field using wavelet analysis method is effective for tunnel fire alarming.
