With the rapid development of economy, the proportion of subway in urban traffic is increasing, which also brings new fire safety hazards. Metro linear temperature fire detection system can accurately detect the temperature distribution within the full length of the tunnel, monitor the temperature in the tunnel in real time and for a long time, and make a reasonable judgment according to the temperature situation by using the empirical value, so as to control the development of the fire before it happens, and truly prevent it from happening. When accidents and fires occur, the alarm will be issued quickly to prevent subsequent vehicles from entering the tunnel and minimize the loss of accidents.
