| Abstract: | This paper summarizes different fire detectors which can sense different representative signals coming from fire. By analysis of their characteristics some of them were chosen for work in tunnel environment, The principles of various conventional tunnel fire detectors were introduced. The tunnels using typical tunnel fire detectors are listed and the effect of these detectors is analyzed. Then the capabilities of two mainstream tunnel fire detectors are compared linear fiber optic sensor and the dual wavelength IR flame detector. At the end of the paper, based on the development of tunnel fire detectors and the advantage and disadvantage of various detectors applied in tunnel, a new fire alarm system is designed which can detect fire and give alarm at the early stage of fire. |
