Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren zur Erkennung von Rauch in einem Raum gemäss Oberbegriff von Anspruch 1.The The present invention relates to a method for detecting smoke in a room according to Preamble of claim 1.
Rauchmelder sind in vielfältiger Form und Ausführung bekannt und auf dem Markt. Sie arbeiten jedoch fast alle nach einem Prinzip. Um detektiert zu werden, muss der Rauch durch den Rauchmelder hindurchströmen. Das Verfahren ist als Streulichtverfahren bekannt und setzt voraus, dass der Rauch mit dem Sensor in Kontakt kommt. Die Folge davon ist, dass Rauchmelder aus der Decke herausragen müssen, ein deckenbündiger Einbau ist nach der hierfür geltenden Europäischen Norm EN54 nicht möglich. Bei der Wartung ist es notwendig, dass der ganze Sensorkopf demontiert und zum Hersteller geschickt wird. In der Praxis werden dabei die Sensorköpfe durch neue ersetzt, da nicht gewartet werden kann, bis die ausgetauschten, vom Hersteller repariert bzw. gewartet zurückkommen. Als Folge davon ist es notwendig, dass die doppelte Menge an Rauchmeldern von den Wartungsfirmen bevorratet wird.smoke detector are in more diverse Shape and design known and in the market. However, they almost all work after one Principle. To be detected, the smoke must flow through the smoke detector. The Method is known as a scattered light method and assumes that the smoke comes into contact with the sensor. The consequence of this is that smoke detectors must stick out of the ceiling flush ceiling Installation is according to the applicable European Standard EN54 not possible. at maintenance it is necessary that dismantles the whole sensor head and sent to the manufacturer. In practice, the Through sensor heads replaces new ones, because it is not possible to wait until the exchanged repaired by the manufacturer or come back serviced. As a result of this is It is necessary that twice the amount of smoke detectors from the maintenance companies is stored.
Ferner können die handelsüblichen Rauchmelder manipuliert werden, ohne dass es zu einer Detektion der Manipulation kommt. Darüber hinaus ist es notwendig, dass jeder einzelne Rauchmelder zum Schaltschrank hin verdrahtet wird.Further can the commercial ones Smoke detectors are manipulated without causing a detection the manipulation comes. About that In addition, it is necessary that every single smoke detector to the control cabinet is wired.
Ein weiterer Nachteil der bekannten Rauchmelder liegt darin, dass diese in der Praxis leicht verschmutzen. Sind sie verschmutzt, können sie aber keinen Rauch mehr detektieren.One Another disadvantage of the known smoke detector is that this easily soiled in practice. If they are dirty, they can but no longer detect smoke.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde eine Vorrichtung der o. g. Art zu schaffen, mit welcher auf einfache Art und Weise tatsächlich vorhandener Rauch in einem freien Raum detektiert wird und Falschmeldungen durch Schmutz oder Manipulation auf der Abdeckung aber auch von Fremdkörper im Raum vermieden werden.Of the The present invention is based on a device the o. g. To create kind, with which in a simple way actually existing Smoke in a free space is detected and false announcements due Dirt or manipulation on the cover but also of foreign objects in the Space to be avoided.
Zur Lösung dieser Aufgabe führen die Merkmale von Anspruch 1.to solution lead this task the features of claim 1.
Das bedeutet, dass nicht schon jede Abweichung der Reflektion zu einem Alarm od. dgl. führt. Beispielsweise ist ein Insektenvorbeiflug, der zufällig die Strahlung reflektiert, ebenso zu übergehen, wie eine Putzfrau mit einem Staubwedel. Deshalb werden durch das Steuerungsprogramm eine Mehrzahl von Erkennungsvorgängen hintereinander addiert. Erst wenn mehrere Erkennungsvorgänge aufeinanderfolgend, eine Abweichung der Reflektion detektieren, kommt es zu einer Alarmauslösung. Auch ein abrupter Anstieg der Abweichung der Reflektion führt noch nicht zu einer Meldung, da bekannt ist, dass Rauch eher zu einem kontinuierlichen Ansteigen einer Reflektionsabweichung führt.The means that not every deviation of the reflection to one Alarm od. Like. Leads. For example is an insect flyby that randomly reflects the radiation, to pass as well like a cleaning lady with a feather duster. Therefore, by the Control program a plurality of recognition processes in a row added. Only if several recognition processes consecutively, one Detect deviation of the reflection, it comes to an alarm triggering. Also an abrupt increase in the deviation of the reflection still results not to a message, since it is known that smoke tends to become one continuous increase of a reflection deviation leads.
Die gesamte Vorrichtung wird bevorzugt als eine Einheit ausgebildet. Sie kann als Stand-Alone-Version ausgebildet sein, wobei die Anschlüsse durch einfache Relais-Ausgänge angesteuert werden.The entire device is preferably formed as a unit. It can be designed as a stand-alone version, with the connections through simple relay outputs be controlled.
Bevorzugt ist jedoch das ganze System durch ein flexibles Mikroprozessorsystem über einen BUS ansteuerbar. Über den BUS kommuniziert jeder Rauchmelder mit einer Zentrale. Dabei kann durch eine Initialisierungssequenz ein Kabelbruch erkannt werden, wodurch ein komplett ausgefallener Rauchmelder ermittelt wird.Prefers however, the whole system is through a flexible microprocessor system over a BUS controllable. about Each smoke detector communicates with the BUS via a central office. there can be recognized by an initialization sequence a cable break, whereby a completely failed smoke detector is determined.
Die erfindungsgemässe Vorrichtung zur Erkennung von Rauch kann auch durch Fremdstrahlung beeinflusst werden. Bei Lichtstrahlung ist dies vor allem eine Sonneneinstrahlung oder eine Strahlung von anderen Lichtquellen, bei Verwendung von Infrarotstrahlung, kann eine Infrarotfernbedienung oder eine Infrarotschnittstelle von einem Drucker zu Irritationen führen. Um dieses auszuschliessen, soll dem Empfänger ein Filter vorgeschaltet werden, der diese Fremdstrahlungen ausfiltert. Wird beispielsweise Licht als Strahlung verwendet, so empfängt der Sensor die gesamte einfallende Lichtstrahlung, wandelt aber nur die Lichtstrahlung mit der ausgesendeten Frequenz in Gleichspannung um, die dann das Sendesignal ergibt. Die übrige Lichtstrahlung wird in Wechselspannung umgesetzt und auf Null gesetzt.The invention Device for detecting smoke can also be caused by extraneous radiation to be influenced. In the case of light radiation, this is primarily solar radiation or radiation from other light sources when using infrared radiation, Can be an infrared remote control or an infrared interface cause irritation from a printer. To exclude this, should be the receiver a filter can be connected upstream, which filters out these extraneous radiations. For example, if light is used as radiation, the sensor receives the entire incident light radiation, but only converts the light radiation with the emitted frequency in DC voltage, then the transmission signal results. The rest Light radiation is converted into AC voltage and set to zero.
