Abstract (en)
The method involves suction of ambient air in a rail vehicle (2) by suction units (10a, 10b) in a monitoring region, where the suction units are operated separately. Monitoring parameters of the suctioned ambient air in the suction units are separately evaluated. A control signal is emitted when a monitoring parameter threshold value is detected in one of the suction units. The ambient air along a monitoring region is suctioned by suction pipes (12a, 14a, 14b) with multiple suction openings, where the suction openings are distributed along an axis. An independent claim is also included for a rail vehicle-fire detection device comprising separately operated suction units.

Verfahren zur Detektion von Bränden in Schienenfahrzeugen. Zur sicheren und fehlerreduzierten Branddetektion wird vorgeschlagen, Raumluft in einem Schienenfahrzeug mittels zumindest zwei getrennt voneinander betriebenen Ansaugeinrichtungen in jeweils einem Überwachungsbereich anzusaugen, den Überwachungsparameter der angesaugten Raumluft in den Ansaugeinrichtungen auszuwerten und ein erstes Steuersignal bei Detektion eines Überwachungsparametergrenzwertes in zumindest einer Ansaugeinrichtung auszugeben.
