Train Fire Detection System on Seikan Tunnel

Abstract

This paper describes a train fire detection system which is set on Seikan tunnel as one of preventing disasters. Seikan tunnel is the longest one in the world, now. So that, two escape points are located in the tunnel to prepare for an emergency. These places are called “Submarine Station”. The train fire detection system inspects all train which pass the tunnel from the ground out of contact. In case this system detects a train on fire, emergency information is sent to Hakodate operation center. And that train is controled to stop at the “Submarine Station”.
This inspection system is an infrared (IR) detection system. The data is processed by computer on two steps which are high temperature check and abnormal hot zone check.
