Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur visuellen Inspektion eines in einem Flugzeug angeordneten Rauchdetektors, der vorzugsweise in dem Abluftkanal einer Flugzeugtoilette Anwendung findet, wobei der Rauchdetektor durch Hindernisse, wie insbesondere Abdeckungen, Verklebungen oder dergleichen, an seiner Eintrittsöffnung oder an einem vorgesehenen Schutzgitter in seiner Funktion eingeschränkt bzw. gehindert wird.The invention relates to a device for the visual inspection of a smoke detector arranged in an aircraft, which preferably finds application in the exhaust duct of an aircraft toilet, the smoke detector by obstacles, in particular covers, adhesives or the like, at its inlet opening or on a protective grille provided in its function restricted or prevented.
Derzeit ist es in allen Flugzeugen, die mit Rauchwarneinrichtungen ausgerüstet sein müssen, notwendig, in den zugänglichen Bereichen wie beispielsweise Toiletten, Mannschaftsruheräumen oder dergleichen regelmäßig visuelle Inspektionen der Rauchsensoren durch die Flugzeugbesatzung durchführen zu lassen. Dieses erfolgt bei Langstreckenflügen etwa alle 15 Minuten und bedeutet, dass eine Überprüfung dahin erfolgt, ob die Rauchdetektoren oder zugeordnete Lüftungszugänge verklebt bzw. abgedeckt sind. Es wird somit bisher durch eine reine visuelle Kontrolle festgestellt, ob Rauchdetektoren im Flugzeug durch vorhandene Hindernisse abgedeckt bzw. zugestellt sind und somit lediglich eine eingeschränkte oder gar keine Funktion von Rauchmeldern gegeben ist. In Bereichen, in denen ungefilterte Luft verwendet wird, können sich solche Blockierungen in nachteiliger Weise sehr schnell aufbauen.At present, in all aircraft which must be equipped with smoke alarms, it is necessary to have regular visual inspections of the smoke sensors by the flight crew in the accessible areas such as toilets, crew rest rooms or the like. This takes place on long-haul flights approximately every 15 minutes and means that a check is made as to whether the smoke detectors or associated ventilation entrances are glued or covered. It is thus so far determined by a pure visual inspection, whether smoke detectors in the aircraft existing obstacles are covered or delivered and thus only a limited or no function of smoke detectors is given. In areas where unfiltered air is used, such blockages can disadvantageously build up very quickly.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, durch welche eine permanente Überwachung von Rauchdetektoren im Hinblick auf eventuelle Blockaden oder Manipulationen automatisch ermöglicht wird.The invention is therefore based on the object to provide a device of the type mentioned, by which a permanent monitoring of smoke detectors with regard to any blockages or tampering is automatically enabled.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass mindestens zwei Luftdrucksensoren in der Nähe des Rauchdetektors angeordnet sind, die aufgrund einer Abdeckung des Rauchdetektors und / oder des Schutzgitters auftretende Luftdruckunterschiede erfassen, und dass den Luftdrucksensoren eine Auswerte- und Anzeigeeinrichtung zur Ermittlung und Anzeige von den Rauchdetektor in seiner Funktion einschränkenden Hindernissen nachgeordnet ist.The object is achieved in that at least two air pressure sensors are arranged in the vicinity of the smoke detector, which detect due to a cover of the smoke detector and / or the protective grid occurring air pressure differences, and that the air pressure sensors an evaluation and display device for detection and display of the smoke detector subordinate in its function limiting obstacles.
Erfindungsgemäße weiterbildungen der Vorrichtung sind in den Unteransprüchen 2 bis 10 beschrieben.Inventive developments of the device are described in the
Es wird in vorteilhafter Weise eine technische Möglichkeit realisiert, die es permanent erlaubt, festzustellen, dass eine Detektion von Rauch in einem Flugzeug durch eine Blockade der Rauchdetektoren eingeschränkt bzw. verhindert wird. Ein wesentlicher Vorteil der Erfindung besteht auch darin, dass durch Betätigungszeiträume eine Fehlreaktion im Falle von kurzfristigen Druckschwankungen, wie z. B. im Falle einer Vakuumtoilette, verhindert werden können. Eine festgestellte Blockade eines Rauchdetektors kann in vorteilhafter Weise lokal, in der Flugzeugkabine oder außerhalb des betroffenen Raumes angezeigt werden bzw. auch einem zentralen Wartungssystem mitgeteilt werden.Advantageously, a technical possibility is realized which allows to permanently determine that a detection of smoke in an aircraft is restricted or prevented by a blockage of the smoke detectors. An essential advantage of the invention is also that by actuation periods a false reaction in the case of short-term pressure fluctuations, such. B. in the case of a vacuum toilet can be prevented. A Detected blockage of a smoke detector can be displayed in an advantageous manner locally, in the aircraft cabin or outside the affected area or be communicated to a central maintenance system.
In der Zeichnung ist ein Ausführungsbeispiel nach der Erfindung dargestellt, und zwar zeigt:
- Fig. 1:
- einen in einer Flugzeugtoilette angeordneten Rauchdetektor, dem insgesamt drei Luftdrucksensoren zugeordnet sind,
und - Fig. 2:
- einen Rauchdetektor mit zwei Luftdrucksensoren und einem Rohrsystem, wobei ein Rohr des Systems der Raucheintrittsöffnung und ein weiteres Rohr der Rauchaustrittsöffnung des Rauchdetektors zugeordnet ist.
- Fig. 1:
- a smoke detector arranged in an aircraft toilet, to which a total of three air pressure sensors are assigned,
and - Fig. 2:
- a smoke detector with two air pressure sensors and a pipe system, wherein a pipe of the system of the smoke inlet opening and a further tube of the smoke outlet opening of the smoke detector is assigned.
In Fig. 1 weist ein Toilettenraum 4 in einem zeichnerisch nicht dargestellten Flugzeug eine Decke 5 auf, in der ein Schutzgitter 6 eingearbeitet ist. Oberhalb des Schutzgitters 6 bzw. der Decke 5 ist ein Rauchdetektor 7 mit zugehöriger Raucheintrittsöffnung 7a befestigt, und zwar an der Innenwand 8a einer Absaughaube 8 eines Abluftkanals 9 des Toilettenraumes 4. In der Nähe des Rauchdetektors 7 befinden sich insgesamt drei Luftdrucksensoren 1, 2 und 3, von denen der erste im Toilettenraum 4, der zweite an der Innenwand 8a der Absaughaube 8 sowie der dritte im Rauchdetektor 7 angeordnet ist.In Fig. 1, a toilet room 4 in a drawing aircraft not shown on a
Jeweils zwei der Luftdrucksensoren 1, 2 oder 3 erfassen Luftdruckunterschiede, die aufgrund einer Abdeckung des Rauchdetektors 7, insbesondere seiner Raucheintrittsöffnung 7a, und / oder des Schutzgitters 6 auftreten, wobei es sich um Verklebungen oder dergleichen handeln kann. Um diese Hindernisse zu erkennen, die den Rauchdetektor 7 in seiner Funktion einschränken oder gar verhindern, ist den Luftdrucksensoren 1, 2 und 3 eine Auswerte- und Anzeigeeinrichtung zur Ermittlung und Anzeige von den Rauchdetektor 7 in seiner Funktion ein-schränkenden Hindernissen nachgeordnet. Beispielsweise wird ein Hindernis an dem, dem Rauchdetektor 7 vorgelagerten Schutzgitter 6 durch den vor der Eintrittsöffnung 7a des Rauchdetektors 7 angeordneten Luftdrucksensor 2 und den im überwachten Raum befindlichen Luftdrucksensor 1 ermittelt. Ein derartiges Hindernis kann auch durch den im Rauchdetektor 7 angeordneten Luftdrucksensor 3 und den im überwachten Raum 4 befindlichen Luftdrucksensor 1 ermittelt werden. Hingegen wird ein die Eintrittsöffnung 7a des Rauchdetektors 7 blockierendes Hindernis durch den im überwachten Raum 4 angeordneten Luftdrucksensor 3 und den vor Eintrittsöffnung 7a des Rauchdetektors 7 angeordneten Luftdrucksensor 2 ermittelt.In each case two of the
Der in Fig. 2 dargestellte Rauchdetektor 7 weist neben seiner Raucheintrittsöffnung 7a auch eine Rauchaustrittsöffnung 7b auf. Beiden Öffnungen ist ein Rohr vorgeschaltet, und zwar der Raucheintrittsöffnung 7a das Rohr 10 und der Rauchaustrittsöffnung 7b das Rohr 11. Während es sich bei dem Rohr 11 um ein normales Rauchaustrittsrohr mit zwei stirnseitigen Öffnungen handelt, ist das Rohr 10 zusätzlich mit einer Vielzahl von Löchern in seiner Rohrwand versehen, durch welche auch ein Raucheintritt in das Rohr quer zu seiner Rohrwand ermöglicht wird. Durch ein, die Rohre 10 und 11 enthaltendes Rohrsystem wird dem Rauchdetektor 7 über seine Raucheintrittsöffnung 7a ein Rauchumfang zugeführt, der gegenüber dem aus Fig. 1 ersichtlichen Rauchdetektor 7 wesentlich erhöht ist. Wird das Rohr 10 durch Abdeckungen, verklebungen oder dergleichen blockiert, so kann dieser Umstand durch den sich bildenden Luftdruckunterschied mit den Luftdrucksensoren 1 und 2 in oben beschriebener Weise ermittelt werden.The
Die Vorrichtung ist auch für eine Anwendung in einem Flugzeugfrachtraum zur Erkennung und Verhinderung von durch Ladung zugestellten Rauchdetektoren 7 vorgesehen.The device is also intended for use in an aircraft cargo hold to detect and prevent charge delivered
