Description

Die vorliegende Erfindung betrifft einen Gefahrenmelder mit mindestens einem Sensor für eine Gefahrenkenngrösse, einer Auswerteelektronik für die Auswertung der Sensorsignale, einer im Folgenden als Alarmindikator bezeichneten optischen Alarmanzeige und einer Kommunikationsschnittstelle für drahtlose Zweiweg-Kommunikation des Gefahrenmelders mit einem Bedienungsmodul.The present invention relates to a hazard detector with at least one sensor for one Hazard parameter, an evaluation electronics for the evaluation of the sensor signals, one in Following optical alarm display and a communication interface called alarm indicator for wireless two-way communication of the hazard detector with an operating module.

Gefahrenmelder werden bekanntlich mehr oder weniger regelmässig gewartet, wobei oft der Wunsch besteht, bei solchen Service-Arbeiten auf die aktuellen Signale des Melders Zugriff nehmen zu können, um diese zu analysieren und detailliert auszuwerten. Wenn die Auswerteelektronik einen Speicher enthält, was bei einem Mikroprozessor oder Mikrokontroller immer der Fall ist und bei einem ASIC (Application-Specified-Integrated-Circuit) der Fall sein kann, dann könnte der Melder zusätzlich bestimmte, während des Betriebs erfasste Daten und Statusinformationen abspeichern, die dann bei passender Gelegenheit, beispielsweise im Rahmen von Servicearbeiten, aus dem Melder ausgelesen und einer Auswertung zugeführt werden könnten. So ist es beispielsweise denkbar, dass der Melder das Grundsignal misst und abspeichert, oder Beinahe-Alarme registriert oder das jeweils erfasste Gefahrensignal speichert. Alle diese Informationen können sinnvoll statistisch ausgewertet werden.As is known, hazard detectors are serviced more or less regularly, with the There is a desire to access the current signals of the detector during such service work to be able to analyze and evaluate them in detail. If the evaluation electronics contains a memory, which is always the case with a microprocessor or microcontroller Is the case and can be the case with an ASIC (Application-Specified-Integrated-Circuit) the detector could additionally determine certain data and status information recorded during operation save it, which is then when the opportunity arises, for example as part of Service work from which detectors could be read and evaluated. For example, it is conceivable that the detector measures and stores the basic signal, or Almost alarms are registered or the respective hazard signal is saved. All of this information can be meaningfully evaluated statistically.

In der US-A-7,704,607 ist eine Einrichtung zur Ferneinstellung von Parametern eines Gassensors mit einem Bedienungsgerät in der Art einer TV-Fernsteuerung beschrieben. Der Gassensor ist an einem explosionssicheren Gehäuse angeordnet, welches die Auswerteelektronik enthält und ebenso wie das Bedienungsgerät eine Infrarot-Kommunikationsschnittstelle für drahtlose Zweiweg-Kommunikation aufweist. Diese Lösung kommt bei in grossen Stückzahlen verkauften und eingesetzten Gefahrenmeldern, wie Rauch- oder Bewegungsmeldern, aus Kostengründen nicht in Frage, weil die Kommunikationsschnittstelle die Melder zu stark verteuern würde.US-A-7,704,607 discloses a device for remote adjustment of parameters of a gas sensor described with an operating device in the manner of a TV remote control. The gas sensor is arranged on an explosion-proof housing that contains the evaluation electronics and, like the control unit, an infrared communication interface for wireless Two-way communication. This solution comes from those sold in large quantities and hazard detectors used, such as smoke or motion detectors, for cost reasons out of the question because the communication interface makes the detectors too expensive would.

In der EP-A-0 872 817 ist ein Gefahrenmelder beschrieben, der eine Kommunikationschnittstelle für die Aussendung von vom Melder aufgenommenen Daten aufweist, welche vorzugsweise durch den Alarmindikator oder eine zusätzliche Infrarotquelle gebildet ist. Die Kommunikationsschnittstelle kann auch einen Empfänger für von einer externen Quelle ausgesandte Daten aufweisen, welcher vorzugsweise durch einen Infrarotempfänger gebildet ist. EP-A-0 872 817 describes a hazard detector which is a communication interface for the transmission of data recorded by the detector, which preferably is formed by the alarm indicator or an additional infrared source. The communication interface can also have a receiver for data sent from an external source, which is preferably formed by an infrared receiver.

Dieser zusätzliche Infrarotempfänger ist im Gehäuseinneren angeordnet und erst nach Abnahme eines Deckels für den Empfang von Daten bereit. Da beispielsweise Brandmelder an der Decke des zu überwachenden Raumes und Bewegungsmelder knapp unterhalb von dieser in einer Höhe von etwa 2m montiert sind, ist diese Lösung für die am stärksten verbreiteten Gefahrenmelder zu umständlich und kommt daher für diese nicht in Frage. Denn ein in einer Höhe von über 2 m montierter Rauch- oder Bewegungsmelder mit einer Kommunikationsschnittstelle, die vor der Kommunikation mit dem Bedienungsmodul eine Manipulation am Melder erfordert, würde vom Markt unter keinen Umständen akzeptiert.This additional infrared receiver is arranged inside the housing and only after acceptance a cover ready for receiving data. For example, since fire detectors on the Ceiling of the room to be monitored and motion detectors just below this in mounted at a height of about 2m, this solution is for the most common hazard detectors too cumbersome and is therefore out of the question for them. Because one at a height of smoke or motion detectors mounted over 2 m with a communication interface, which requires manipulation of the detector before communication with the control module, would never be accepted by the market.

Schon aus Kostengründen würde man eher versuchen, den durch eine licht emittierende Diode (LED) gebildeten Alarmindikator nicht nur als Datensender sondern auch als Datenempfänger zu verwenden. Hier ergibt sich aber das Problem, dass für den Einsatz einer LED als Fotodiode keine Herstellerdaten existieren und somit die Eigenschaften einer LED als Empfänger nicht garantiert sind. Es ist verständlich, dass aus diesem Grund Bedenken bestehen, eine solche optische Kommunikationsschnittstelle in weltweit in Stückzahlen von Millionen verkauften Gefahrenmeldern einzusetzen.For cost reasons alone, one would rather try to use a light-emitting diode (LED) formed alarm indicator not only as a data transmitter but also as a data receiver to use. Here, however, the problem arises that for the use of an LED as a photodiode No manufacturer data exist and therefore the properties of an LED as a receiver do not are guaranteed. It is understandable that there are concerns for this reason Optical communication interface in millions of danger detectors sold worldwide use.

Durch die Erfindung soll nun ein Gefahrenmelder der eingangs genannten Art angegeben werden, dessen Kommunikationsschnittstelle eine bedienungsfreundliche, sichere und ungestörte Kommunikation zwischen Melder und Bedienungsmodul ermöglicht, und welche ausserdem den Gefahrenmelder nur unwesentlich verteuert.The invention is now to provide a hazard detector of the type mentioned at the outset, whose communication interface is user-friendly, safe and undisturbed Communication between detector and control module enables, and what else the hazard detector only marginally more expensive.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass die Kommunikationsschnittstelle einen durch den Alarmindikator gebildeten optischen Sendekanal, und einen induktiven Empfangskanal aufweist.According to the invention, this object is achieved in that the communication interface an optical transmission channel formed by the alarm indicator, and an inductive reception channel having.

Eine erste bevorzugte Ausführungsform des erfindungsgemässen Melders ist dadurch gekennzeichnet, dass der Empfangskanal im wesentlichen einen Resonanzkreis und einen diesem nachgeschalteten Demodulator aufweist.A first preferred embodiment of the detector according to the invention is characterized in that that the receiving channel is essentially a resonant circuit and one of these has downstream demodulator.

Der erfindungsgemässe Gefahrenmelder hat den Vorteil, dass durch die Trennung der Kommunikationsschnittstelle in einen optischen Sendekanal und einen induktiven Empfangskanal die Kosten der Kommunikationsschnittstelle bei einer gleichzeitig sicheren und zuverlässigen Kommunikationsverbindung sehr niedrig gehalten werden. Denn der Alarmindikator ist ohnehin vorhanden und der induktive Empfangskanal mit dem Resonanzkreis und dem Demodulator ist äusserst kostengünstig.The hazard detector according to the invention has the advantage that by separating the communication interface into an optical transmission channel and an inductive reception channel Cost of the communication interface with a secure and reliable communication connection be kept very low. Because the alarm indicator is there anyway and is the inductive receive channel with the resonant circuit and the demodulator extremely inexpensive.

Gemäss einer weiteren bevorzugten Ausführungsform ist dem Demodulator ein Pulsformer nachgeschaltet, dessen Ausgang mit einem Mikroprozessor verbunden ist. Dieser Mikroprozessor bildet vorzugsweise Teil der Auswerteelektronik des Gefahrenmelders. According to a further preferred embodiment, the demodulator is a pulse shaper downstream, the output of which is connected to a microprocessor. This microprocessor preferably forms part of the evaluation electronics of the hazard detector.

Die Erfindung betrifft weiter ein Bedienungsmodul für einen Gefahrenmelder der genannten Art, mit einer einen Sender und einen Empfänger aufweisenden Kommunikationsschnittstelle. Das erfindungsgemässe Bedienungsmodul ist dadurch gekennzeichnet, dass der Empfänger durch eine Fotodiode und der Sender durch eine Induktivität gebildet ist.The invention further relates to an operating module for a hazard detector of the type mentioned, with a communication interface having a transmitter and a receiver. The Operating module according to the invention is characterized in that the receiver is characterized by a photodiode and the transmitter is formed by an inductor.

Eine erste bevorzugte Ausführungsform des erfindungsgemässen Bedienungsmoduls ist dadurch gekennzeichnet, dass das Bedienungsmodul durch ein auf den Gefahrenmelder aufsetzbares Prüfwerkzeug gebildet ist.This is a first preferred embodiment of the control module according to the invention characterized in that the control module can be placed on the hazard detector Test tool is formed.

Eine zweite bevorzugte Ausführungsform des erfindungsgemässen Bedienungsmoduls ist dadurch gekennzeichnet, dass das Prüfwerkzeug ein so genannter Melderprüfer oder Melderaustauscher mit einem an einer Stange befestigten Prüf-/Pflückkopf ist.A second preferred embodiment of the control module according to the invention is characterized in that the test tool is a so-called detector tester or detector exchanger with a test / picking head attached to a rod.

Mit dem Prüf-/Pflückkopf ist einerseits die Funktion von Streulichtrauchmeldern überprüfbar und andererseits der Melder in seinen Sockel einsetzbar und aus diesem heraus nehmbar. Der letztere Vorgang wird auch als "Melderpflücken" bezeichnet.The function of scattered light smoke detectors can be checked and checked with the test / picking head on the other hand, the detector can be inserted into and removed from its base. The latter The process is also known as "picking the detector".

Eine dritte bevorzugte Ausführungsform ist gekennzeichnet durch ein Bedienungsteil in der Art einer Fernbedienung oder eines Handheld, mit einem Tasten- und/oder einem Anzeigefeld.A third preferred embodiment is characterized by an operating part of the type a remote control or a handheld, with a keypad and / or a display panel.

Die Kommunikationsschnittstelle ermöglicht nicht nur die Eingabe von Daten in den Melder, was Wartungs- und Revisionsarbeiten wesentlich erleichtert, sondern sie ermöglicht auch eine bidirektionale Kommunikation zwischen dem Bedienungsmodul und der Zentrale der betreffenden Gefahrenmeldeanlage. Letzteres erleichtert die Inbetriebnahme des Melders, bei der es bekanntlich unter anderem um die so genannte Lokalisierung des Melders geht. Darunter versteht man die Verknüpfung der logischen Adresse des Melders, unter der dieser in der Zentrale gespeichert ist, mit der physikalischen Adresse (z.B. Raumnummer), was durch Eingabe eines entsprechenden Befehls am Bedienungsmodul erfolgen kann.The communication interface not only enables data to be entered into the detector, what Maintenance and revision work much easier, but it also enables bidirectional Communication between the control module and the control center of the concerned Alarm system. The latter facilitates the commissioning of the detector, where it is known among other things, the so-called localization of the detector. That means one the link of the logical address of the detector under which this in the central is saved with the physical address (e.g. room number), which can be done by entering a corresponding command on the control module.

The wire loop 9 is inserted into the test head of the detector tester, which is pushed onto detectors containing the resonant circuit 10 for each transmission process. The photodiode 4 is arranged in the test head in such a way that the light emitted by the alarm indicator 1 is applied to it. This can be achieved, for example, by mechanical coding, which only allows the test head to be pushed onto the detector in a single relative position.

Der Prüfkopf ist auf eine Muffe aufgesetzt, in die ein Rohrstutzen eingesetzt ist. Auf den Rohrstutzen kann ein Verlängerungsrohr geschoben werden, wobei mit mehreren dieser mit Rohrschellen verbindbaren Verlängerungsrohre Melder bis zu einer Raumhöhe von etwa 7 m überprüft werden können. An einer für die Bedienungsperson geeigneten Stelle der durch die Verlängerungsrohre gebildeten Stange ist ein in der Art einer Fernbedienung oder eines Handheld ausgebildetes Bedienungsteil angeordnet, das ein Display und ein Tastenfeld mit Navigationstasten und einer Ein-/Austaste enthält. Zwischen diesem Bedienungsteil und der Kommunikationsschnittstelle KB besteht eine Kommunikationsverbindung, beispielsweise nach dem IrDA- oder dem Bluetooth-Standard, oder für einfache Bedienungsmodes eventuell über eine optische Anzeige am Prüfkopf, oder auch über ein Kabel.The test head is placed on a sleeve into which a pipe socket is inserted. On the pipe socket an extension pipe can be pushed, with several of these with pipe clamps connectable extension tubes detectors up to a room height of approx. 7 m can be checked. At a location suitable for the operator by the operator Extension tube formed rod is one in the manner of a remote control or a handheld trained operating part arranged with a display and a keypad Contains navigation buttons and an on / off button. Between this operating part and the Communication interface KB there is a communication connection, for example to the IrDA or the Bluetooth standard, or possibly for simple operating modes an optical display on the test head or via a cable.

Selbstverständlich braucht das Bedienungsmodul nicht durch einen Prüfkopf der beschriebenen Art gebildet zu sein. Der Prüfkopf ist für an der Decke montierte Brandmelder optimal geeignet, für an der Wand montierte Melder, wie beispielsweise lineare Rauchmelder oder Handtaster wird man ein an die Form dieser Melder angepasstes Bedienungsmodul verwenden.Of course, the operating module does not need the test head described Kind of being educated. The test head is ideal for fire detectors mounted on the ceiling, for wall-mounted detectors, such as linear smoke detectors or hand switches an operating module adapted to the shape of these detectors will be used.

Zum Start eines Datenaustausches zwischen Melder und Bedienungsmodul wird der Prüfkopf auf den Melder geschoben und auf diesem positioniert. Dann setzt sich der Melder nach Aufforderung durch die Modul-Kommunikationsschnittstelle KB in einen Datentransfermodus. The test head is used to start data exchange between the detector and the operating module pushed onto the detector and positioned on it. Then the detector follows up Requested by the module communication interface KB in a data transfer mode.

Der Melder kann sich auch selbständig in den Datentransfermodus setzen, wenn sich ein Bedienungsmodul als erlaubtes Modul zur Datenübertragung authentifiziert oder identifiziert. Diese Authentifizierung kann durch spezielle Codes oder kryptologische Verfahren erfolgen. Dadurch wird verhindert, dass ein anderes oder unerlaubtes Gerät den Melder versehentlich oder absichtlich in den Datentransfermodus setzt.The detector can also put itself into data transfer mode if there is a Operating module authenticated or identified as a permitted module for data transmission. This authentication can take place using special codes or cryptological methods. This prevents another or unauthorized device from accidentally entering the detector or intentionally puts in data transfer mode.

Im Datentransfermodus kann einerseits der Melder während des Betriebs erfasste und gespeicherte Daten, beispielsweise Beinahe-Alarme und dergleichen, an das Bedienungsmodul senden, und anderseits können an den Melder Daten oder Befehle, wie beispielsweise Instruktionen in Zusammenhang mit Servicearbeiten oder Parameter, übertragen werden. Eventuell können im Datentransfermodus auch Software-Updates vorgenommen werden.In data transfer mode, on the one hand, the detector can record and save data during operation Data, for example near-alarms and the like, to the operating module send, and on the other hand, data or commands, such as instructions, to the detector in connection with service work or parameters. Perhaps software updates can also be carried out in data transfer mode.

Der Datentransfermodus kann auch zur Herstellung einer bidirektionalen Verbindung zwischen dem Bedienungsmodul und der Zentrale der Gefahrenmeldeanlage über den jeweiligen Melder verwendet werden, indem beispielsweise der Zentrale mitgeteilt wird, dass an dem Melder Servicearbeiten durchgeführt werden oder die Zentrale aufgefordert wird, den Melder in einen entsprechenden Modus zu schalten. Insbesondere bei der Montage einer Brandmeldeanlage mit einer Vielzahl von Meldern kann die Möglichkeit der Zweiweg-Kommunikation zwischen Zentrale und Bedienungsmodul sehr hilfreich sein, indem die zugehörige Raumnummer am Bedienungsmodul eingegeben und vom Melder zur Zentrale übertragen wird, wo dann eine Verknüpfung der Raumnummer mit der Melder-Identifikationsnummer (siehe dazu EP-A-0 546 401) und damit eine eindeutige Lokalisierung des Melders erfolgt,.The data transfer mode can also be used to establish a bidirectional connection between the control module and the control center of the hazard detection system via the respective detector can be used, for example, by notifying the control panel that the detector Service work is carried out or the control panel is asked to switch the detector into one to switch the corresponding mode. Especially when installing a fire alarm system With a variety of detectors, the possibility of two-way communication between Central and control module can be very helpful by the associated room number on Operating module is entered and transmitted from the detector to the control center, where a Linking the room number with the detector identification number (see EP-A-0 546 401) and thus the detector is clearly localized.
