Embodiment Construction

[0028] figure 1 A rail vehicle 2 is shown having an upper deck 4 and a lower deck 6 separated by a partition 8 . Furthermore, a first suction device 10 a and a second suction device 10 b are provided in the rail vehicle 2 . Suction pipes 12a and 14a are provided on the first suction device 10a. Suction pipes 12b and 14b are connected to the second suction device 10b. As can be seen, the intake pipes 12 a and 12 b run in the upper deck 4 of the rail vehicle 2 . In this illustration, the suction duct 12a is in the upper region of the upper layer 4 and the suction duct 12b is in the lower region of the upper layer 4 . It is also possible to arrange both suction pipes 12 a , 12 b at a distance from one another in the roof or bottom of the rail vehicle 2 .

[0029] Furthermore, it can be seen that the intake pipes 14 a , 14 b are arranged in the lower level 6 of the rail vehicle 2 .

[0030] The suction devices 10a, 10b suck air into the upper level 4 or the lower level 6 thro...

Abstract

The invention relates to a method for detecting fire in rail vehicles. For the safe and error-reduced fire detection, the invention proposes for the cabin air in a rail vehicle to be suctioned by at least two separately operated suction units into a monitoring region, to evaluate the monitoring parameter of the suctioned cabin air in the suction units and to emit a first control signal when a monitoring parameter threshold value is detected in at least one suction unit.

Description

technical field [0001] The invention relates to a method and a device for fire detection in rail vehicles. In particular, a fire detection that is as fail-safe as possible should be provided in passenger cars. Background technique [0002] Error-free smoke detection is of great importance in rail vehicles. Especially in cases where the fire hazard posed by the passengers is uncontrollable, the resulting fire spreads very quickly and countermeasures must therefore be taken very quickly. For example, firefighting equipment must be provided in order to be able to react very quickly to an emerging fire. If the intrusion of fire is involved, then in the event of a failure of the fire fighting equipment, in most cases the damage is severe, so that redundancy in the smoke detection must be obliged. [0003] In known rail vehicles, the smoke detectors are arranged electrically interconnected in the carriage. If the smoke detector is impacted, an alarm signal is generated, whereb...
