Equipment for controlling a train fire in a long railway tunnel and method for implementing same
First Claim
1. Equipment for controlling a train fire in a long railway tunnel, comprising:
- a set of fixed fire detectors installed along the tunnel;
a set of detectors installed on board trains;
at least one fixed extinguishing station, installed in the tunnel over a length at least equal to the length of a train, and comprising;
extinguishing equipment with devices for spraying an extinguishing fluid, these devices being individually controlled and distributed over the length of the extinguishing station, anda set of fire detectors installed along the station and operative to detect a position of a fire in a detected one of said trains;
a train stopping area, upstream of the extinguishing station, in which in use the detected train slows down to its zero speed so that it can be stopped in a predetermined precise position in the extinguishing station;
a control center, connected to the fixed fire detectors and to the fire detectors of the extinguishing station to receive fire signals therefrom and operative to;
monitor fire information by reconciling the fire signals received,order a reduction of the speed of the detected train from its normal running speed to a reduced safety speed,order the detected train to stop in the extinguishing station, including ordering the train to start a stopping sequence on entering the stopping area and to stop the train in the predetermined precise position in the extinguishing station,detect after the train stops, using the set of fire detectors installed along the extinguishing station, a position of the fire in the selected train,automatically configure the extinguishing fluid spraying devices with respect to the detected position of the fire and surrounding areas in the extinguishing station, andcommand spraying by the extinguishing fluid spraying devices to commence as soon as the train stops.

Abstract
The invention relates to equipment including fixed fire detectors (10) along the track (100) and fixed extinguishing stations (20) installed in the tunnel. Each station is provided with fire detectors (23) for locating the source, an automatic configuration system for targeting the area to be sprayed, individually controlled spraying devices (22), and a device for remotely or locally activating the spray. The station is preceded by a train stopping area (ZA) in which the train (TRO) starts a stopping sequence and slows down from the safety speed thereof to the zero speed thereof. A control center (30) manages the operation of the equipment and in particular orders a reduction of the train (TRO) running speed when the detectors (10) have detected a fire (flames, smoke, CO). The reduced speed (safety speed (Vs)) enables the train (TRO) to run as quickly as possible while mitigating the progression of the fire.

11. A method for controlling a train fire in a long railway tunnel wherein the tunnel comprises at least one fire extinguishing station equipped with extinguishers spaced apart along the station, comprising:
-
detecting trains are as they pass in front of fire detectors; if a fire is detected on a detected one of the trains, monitoring from a control position a fire signal transmitted by the fire detectors; from the control position, ordering the driver of the detected train to travel at a set safety speed that is lower than a normal running speed and that stabilizes the fire;
after the train has started to run at the safety speed, ordering the driver to stop the train at said fire extinguishing station; and
after the train has stopped in the extinguishing station;
detecting a position of the fire along the train;automatically pre-configuring areas along the train to be extinguished; and
activating the extinguishers of only the pre-configured areas of the extinguishing station. - View Dependent Claims (12)
