ROAD TUNNELS – LINEAR HEAT DETECTION USING FIBER
The sensing cable is suspended from a tunnel ceiling by use of various fixing methods. If the sensing cable is installed in a straight line (along the line of sight of the tunnel), fixings should be installed on
Layout of the fiber optic cables in the tunnel: (a) typical
The fiber–optic strain sensing cables, similar to human nerves, are capable of capturing slight movements in a distributed sensing and nearly real–time manner.
