Description

Die Erfindung betrifft eine optische Detektoreinrichtung zur Branderkennung nach dem Oberbegriff des Anspruchs 1.The invention relates to an optical detector device for fire detection according to the preamble of claim 1.

Zum Erkennen von Bränden sind aus DE 28 19 183 C2 und DE 42 00 340 C2 optische Detektoren bekannt, die auf Strahlung ansprechen, die bei der Verbrennung emittiert wird. Beschrieben ist eine Feuererfassungs-Messeinrichtung des Typs, der einen selektiven Feuererfassungsteil zur Detektion von wenigstens zwei verschiedenen Spektralbändern einschließt, wie sie bei einem Feuer auftreten, und der ein Ausgangssignal als Reaktion auf vorbestimmte Mengen dieser Strahlung in den Spektralbändern erzeugt, wie sie eine bestimmte Größe und Art des zu detektierenden Feuers aufweist. Auf Basis optischer Auslösefaktoren reagierende Systeme sind kommerziell erfolgreich und stellen ihren Nutzen in verschiedenen militärischen und zivilen Feuererfassungs- und Unterdrückungssystemen unter Beweis.To detect fires are off DE 28 19 183 C2 and DE 42 00 340 C2 optical detectors are known which respond to radiation emitted during combustion. Described is a fire detection measuring device of the type including a selective fire detection part for detecting at least two different spectral bands as they occur in a fire, and which generates an output signal in response to predetermined amounts of this radiation in the spectral bands, such as a certain size and type of fire to be detected. Systems based on optical triggering factors are commercially successful and demonstrate their utility in various military and civilian fire detection and suppression systems.

Erforderlich bei solchen optischen Detektoren ist, dass die Strahlungsintensität eine bestimmte Schwelle überschritten haben muss, damit der optische Detektor anspricht. Zum Überwachen eines Raumbereiches, beispielsweise eines Fahrzeuginnenraumes, sind deshalb mehrere Detektoren mit unterschiedlichen Blickfeldern mit Abstand zueinander angeordnet und mit einer zentralen Auswerteeinheit zum Empfangen und Auswerten von Signalen der Detektoren verbunden.What is required in such optical detectors is that the radiation intensity is a certain threshold must have exceeded for the optical detector to respond. For monitoring a spatial area, for example a vehicle interior, a plurality of detectors with different fields of view are therefore arranged at a distance from one another and connected to a central evaluation unit for receiving and evaluating signals from the detectors.

Die Überlebensfähigkeit der Fahrzeuginsassen und des Fahrzeuges selber erhöhen sich. Eine frühzeitige Erkennung eines Feuers, um dieses dann automatisch löschen zu können, bietet folglich Schutz vor Brandrisiken durch eine solche Feuererfassung und Brandunterdrückung.The survivability of the vehicle occupants and the vehicle itself increase. Early detection of a fire, in order to be able to automatically extinguish it, thus provides protection against fire risks by such fire detection and fire suppression.

Nachteilig ist, dass Voraussetzung für die optimale Funktion der mehreren Detektoren ist, dass die Anzahl und Position der Detektoren beim Einbau richtig festgelegt wird. Nur dann wird, egal wo das Feuer entsteht, dieses erkannt und kann innerhalb weniger Millisekunden gelöscht werden. Zudem können Inneneinrichtungen die Positionierung behindern.The disadvantage is that the prerequisite for the optimal function of the plurality of detectors is that the number and position of the detectors is correctly determined during installation. Only then, no matter where the fire originates, it is detected and can be deleted within a few milliseconds. In addition, interior furnishings can hinder the positioning.

Aufgabe der Erfindung ist es daher, eine optische Detektoreinrichtung zur Branderkennung zu schaffen, die die Feuererfassung zum Auslösen eines Löschvorganges verbessert.The object of the invention is therefore to provide an optical detection device for fire detection, which improves the fire detection to trigger a deletion process.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Hierdurch wird eine optische Detektoreinrichtung zur Branderkennung geschaffen, die eine zentrale Einheit zur Deckenmontage ist. Eine derartige Ausbildung ist kompakt und legt bereits vor dem Einbau der Detektoren deren Anordnung zueinander fest, wodurch eine zuverlässige Abtastung eines Raumes sichergestellt werden kann.This object is solved by the features of claim 1. As a result, an optical detection device for fire detection is created, which is a central unit for ceiling mounting. Such a design is compact and determines their arrangement to each other even before the installation of the detectors, whereby a reliable scanning of a room can be ensured.

Die mehreren Detektoren sind als Einzeldetektoren an dem Deckenhalter zusammengesetzt, wobei jeder Einzeldetektor in eine zumindest geringfügig andere Richtung blickt aufgrund der kalottenförmigen Ausbildung des Deckenhalters. Die zentral zueinander ausgerichteten Einzeldetektoren setzen aus ihren einzelnen Blickfeldern ein optisches Abtastbild des zu überwachenden Raumes zusammen. Die Anzahl der Einzeldetektoren und die jeweilige Position am Deckenträger sind dazu variierbar. Die Anordnung erfolgt allerdings vorzugsweise starr, wenn feste Voreinstellungen vorgenommen werden.The plurality of detectors are assembled as individual detectors on the ceiling mount, wherein each individual detector looks in an at least slightly different direction due to the dome-shaped design of the ceiling mount. The centrally aligned individual detectors set from their individual Fields of view, an optical scanning of the space to be monitored together. The number of individual detectors and the respective position on the ceiling support can be varied. However, the arrangement is preferably rigid when fixed presets are made.
