Definitions
- the invention relates to a method for the freely selectable assignment of detector addresses in a hazard detection system with a plurality of two-wire primary reporting lines and per primary reporting line a plurality of chain-connected hazard detectors, which for this purpose have a switching device in at least one line core, the individual hazard detectors being cyclically activated from the central station their respective alarm signals are queried and the respective physical detector address is stored in the control center due to the chain connection.
- the individual detectors of a primary reporting line are automatically addressed by the arrangement on the line.
- the individual detectors of a primary reporting line are connected to the control center in a chain, the analog measured value of the detector being transmitted and the address of the respective hazard detector being ascertained.
- the hazard detector closest to the control center automatically receives the physical reporting address 1 and the next one the physical reporting address 2 etc.
- This addressing method has the advantage that it takes place independently and reliably, in contrast to other methods in which the detector addresses are set using switches or plugs Need to become. Incorrect settings of the address may be accidentally made.
- EP-A1-0 093 872 describes a method for the transmission of measured values in a transmission system, which makes it possible to write a detector address in each detector in an address memory provided for this purpose.
- the address memory is assigned the address of the relevant measuring point in a predetermined order from the signaling center. So only the known detector address is permanently stamped into the detector itself. An individual or freely selectable assignment of the detector address is not possible with the known method.
- detector addresses are only determined by the detector arrangement on the primary signal line, that these addresses could change when further detectors are inserted later, and that all detectors are always queried in one cycle have to.
- the object of the invention is therefore to provide a method for addressing the individual detectors of a primary detector line in a hazard detection system which operates according to the chain synchronization principle, which allows the detectors to be freely selected, for example according to organizational ones, without address setting in the detector or in the version Aspects, to address and query.
- an address memory is provided in each hazard detector, in which an individual or organizational detector address is written in from the control center in an initialization phase, which address is then used for the operation of the hazard detection system will be that an electrical connection can be made in each detector for the switchable cable core if there is no danger detector in the detector is that with the commissioning of the hazard alarm system (initialization phase) for each primary alarm line an automatic address assignment is carried out by the order of equipping the detectors with hazard detectors, that a first physical address is assigned and stored in the control center to the first plugged-in hazard detector, which is then assigned by the control center from the hazard detector concerned, it is asked for its organizational detector address, that the control center, in the absence of an organizational detector address, assigns and transmits a first organizational detector address to the relevant hazard detector, where it is written into a non-volatile memory, that a second physical address is assigned
- Each detector therefore has a memory, which the control center supplies with a special (initialization) with an individual (organizational) address and any additional data.
- the control center contains a stored assignment table which assigns an organizational detector address to each physical detector address determined by the chain synchronization. This table is either entered separately at the control center, or is produced without such an entry that the assignment takes place automatically with the order of the detector.
- hazard detectors which are queried according to the chain synchronization method, are automatically provided with an organizational detector address with any line routing and without supply in the control center and without address setting in the detector or in the detector detection.
- the addresses are assigned automatically by the order in which the detectors of a primary alarm line are equipped with the individual hazard alarms. The operator does not need to know the exact cable routing and therefore the physical detector address or the person commissioning the hazard detection system.
- 1 to 5 an example of a control center with a primary reporting line, to which a large number of hazard detectors with different physical detector addresses and organizational detector addresses are connected.
- FIG. 1 shows a control center Z with a primary signal line ML with the detectors M1 to Mn, to which the physical addresses PHA 01 to n are also assigned.
- the detector addresses should now correspond to room number RNr, which, however, do not correspond to the physical detector addresses PHA.
- Such a spatial orientation would be feasible, for example, by assigning the organizational address ORA to the physical detector addresses PHA, which are known, by entering them into the data memory of the control center. This manual entry requires a lot of time and extraordinary care.
- the organization of the detector address assignment takes place automatically with the sequence of the detector population.
- a primary signal line ML is put into operation again.
- all MF detector sockets are initially empty.
- one wire of the signaling primary line ML e.g. b wire
- the line between sockets 4 and 5 is always interrupted.
- the sockets MF not equipped with detectors have an electrical connection between these two terminals 4 and 5. This can be produced, for example, in that an inserted socket cover connects the terminals 4 and 5 to one another.
- a switch FS can be provided in the socket, which is opened automatically when the detector is plugged in.
- the method according to the invention has the following steps.
- the primary signal line ML is set to the initialization state by means of an appropriate input, for example a switch or command in the central station Z.
- the detector M1 which is to receive the organizational detector address ORA 01, is used first.
- the control center Z recognizes a detector M1, since all previous versions MF are connected through the contacts FS, and assigns the physical detector address PHA 01 to it. Subsequently, it asks the detector M1 whether it has already been provided with an organizational address ORA. Since the newly inserted detector does not yet have an organizational address, the central Z assigns it the organizational detector address ORA 01, which is then transmitted from the central Z to the detector M1 and is not stored there in a volatile manner.
- the organizational detector address ORA 01 is assigned to the physical address in the control center and also saved.
- the completion of this addressing can advantageously be acknowledged, for example in the control center and, moreover, also when the detector is plugged in, by the detector indicator attached there flashing.
- the detector M2 which is to receive the organizational address ORA2 is inserted.
- the control center Z now recognizes two detectors M1 and M2, to which it assigns the physical addresses PHA 01 and 02 according to their sequence according to the chain synchronization principle. It then checks whether both detectors M1, M2 have already been supplied with organizational addresses ORA. In the example shown, the detector M1 has already been supplied with the organizational address ORA 01, the organizational address ORA 02 is assigned to the newly inserted detector M2, stored and also transmitted.
- a third detector M3 is inserted.
- the central station Z assigns the three detected detectors M1 to M3 to the physical detector addresses PHA 01 to 03. Since the last inserted detector M3 was inserted before the existing detectors M1 and M2, all physical detector addresses PHA are now shifted.
- the control center Z checks again, as previously described, whether the detectors M1 to M3 have already been supplied with organizational addresses ORA. This is not yet the case with detector M3 with the physical address PHA 01, which is why it is given the organizational address ORA 3. In the same way, all other detectors are inserted into the ML line in the desired organizational order and are thus automatically supplied until the desired one - in this example according to Fig.1 - shown state is reached.
- the organizational addresses assigned to the detectors remain unchanged. After the primary primary line has been fully equipped, it is armed in the control center, i.e. it is switched to the normal operating state. Now, as is known, the detectors can either be continuously queried using the chain synchronization method and their data transmitted to the control center. An address transfer is not necessary because each detector can be clearly identified based on its physical address. Using the assigned organizational addresses stored in the head office, the required organizational address can be selected for further processing and the relevant detectors can thus be specifically addressed. In a known manner, the number of connected detectors is determined and stored even in the initialization phase. If, for example, someone removed a detector, the non-equipped detector socket would automatically connect the line. The control center would find that the number of detectors has decreased.
- control panel can immediately recognize and display the absence of the detectors as a malfunction or sabotage, while still cyclically polling the detectors that are still in operation.
- the principle of chain synchronization can only be used to determine the address according to the invention, while the hazard detectors can transmit their data to the control center by another method.
- the switching transistors in the hazard detectors remain switched through so that all detectors are connected in parallel to the detection line.
- the detectors it is also possible for the detectors to report independently when they have information to transfer and then to transmit their organizational address stored in the detector for identification.
- an organizational detector address can be assigned by triggering the detectors (on site) to assign the organizational addresses.
- the process described above can then be fully transferred to this process if, instead of using a detector, the corresponding detector is triggered, for example by spraying with smoke.
- the addressing method according to the invention has a number of advantages.
- a simple assignment of the organizational addresses is necessary in the context of activities to be carried out anyway, e.g. Detector plugging or triggering of detectors possible without having to take the actual cable routing into account or being aware of it.
- a corresponding supply in the head office, i.e. an additional operation and the associated sources of error are eliminated.
- This method does not require any mechanical or technical effort to set the address, such as actuating a series of switches, writing in the control panel with address numbers or making solder bridges. No special hardware elements are necessary either.
Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zur frei wählbaren Vergabe von Melderadressen in einer Gefahrenmeldeanlage mit mehreren zweiadrigen Meldeprimärleitungen und pro Meldeprimärleitung einer Vielzahl von kettenförmig anschaltbaren Gefahrenmeldern, die dazu in mindestens einer Leitungsader eine Schaltvorrichtung aufweisen, wobei die einzelnen Gefahrenmelder von der Zentrale aus zyklisch auf ihre jeweiligen Meldesignale abgefragt werden und in der Zentrale aufgrund des kettenförmigen Anschaltens die jeweilige physikalische Melderadresse gespeichert ist.The invention relates to a method for the freely selectable assignment of detector addresses in a hazard detection system with a plurality of two-wire primary reporting lines and per primary reporting line a plurality of chain-connected hazard detectors, which for this purpose have a switching device in at least one line core, the individual hazard detectors being cyclically activated from the central station their respective alarm signals are queried and the respective physical detector address is stored in the control center due to the chain connection.
In einer Gefahrenmeldeanlage nach dem Kettensynchronisationsprinzip, wie es beispielsweise in der DE-OS 25 33 382 beschrieben ist, werden die einzelnen Melder einer Meldeprimärleitung automatisch durch die Anordnung auf der Leitung adressiert. Bei der bekannten Gefahrenmeldeanlage werden die einzelnen Melder einer Meldeprimärleitung kettenförmig an die Zentrale angeschaltet, wobei der analoge Meßwert des Melders übertragen und die Adresse des jeweiligen Gefahrenmelders festgestellt wird. Das heißt, daß der der Zentrale am nächsten liegende Gefahrenmelder automatisch die physikalische Meldeadresse 1 und der nächste die physikalische Meldeadresse 2 usw. erhält. Bei der bekannten Gefahrenmeldeanlage ist weder eine Adresseneinstellung im Melder noch in der Melderfassung nötig. Dieses Adressierverfahren hat den Vorteil, daß es selbständig und zuverlässig erfolgt im Gegensatz zu anderen Verfahren, bei denen die Melderadressen über Schalter oder Stecker eingestellt werden müssen. Dabei können versehentlich Falscheinstellungen der Adresse möglich sein.In a hazard detection system based on the chain synchronization principle, as described, for example, in DE-OS 25 33 382, the individual detectors of a primary reporting line are automatically addressed by the arrangement on the line. In the known hazard detection system, the individual detectors of a primary reporting line are connected to the control center in a chain, the analog measured value of the detector being transmitted and the address of the respective hazard detector being ascertained. This means that the hazard detector closest to the control center automatically receives the
In der EP-A1-0 093 872 ist ein Verfahren zur Übertragung von Meßwerten in einem Übertragungssystem beschrieben, welches es ermöglicht, in jeden Melder eine Melderadresse in einem dafür vorgesehenen Adressenspeicher einzuschreiben. Dabei wird der Adressenspeicher bei der kettenförmigen Anschaltung der Melder in vorgegebener Reihenfolge von der Signalzentrale aus mit der Adresse der betreffenden Meßstelle belegt. Es wird also nur die an sich bekannte Melderadresse im Melder selbst fest eingeprägt. Eine individuelle bzw. frei wählbare Vergabe der Melderadresse ist mit dem bekannten Verfahren nicht möglich.EP-A1-0 093 872 describes a method for the transmission of measured values in a transmission system, which makes it possible to write a detector address in each detector in an address memory provided for this purpose. When the detectors are connected in a chain, the address memory is assigned the address of the relevant measuring point in a predetermined order from the signaling center. So only the known detector address is permanently stamped into the detector itself. An individual or freely selectable assignment of the detector address is not possible with the known method.
Bei dem bekannten Verfahren zur Vergabe von Melderadressen muß allerdings in Kauf genommen werden, daß die Melderadressen nur durch die Melderanordnung auf der Meldeprimärleitung bestimmt sind, daß sich diese Adressen beim späteren Einfügen weiterer Melder ändern könnten, und daß in einem Zyklus immer alle Melder abgefragt werden müssen.In the known method for assigning detector addresses, however, it must be accepted that the detector addresses are only determined by the detector arrangement on the primary signal line, that these addresses could change when further detectors are inserted later, and that all detectors are always queried in one cycle have to.
Häufig ist es jedoch erforderlich oder gewünscht, einzelne Melder rasch, andere dagegen nur selten abzufragen, oder, beispielsweise aus organisatorischen Gründen, die Gefahrenmelder einer Meldeprimärleitung nicht nach den Gesichtspunkten ihrer Reihenfolge, wie sie auf der Melderprimärleitung angeschlossen sind, zu adressieren, d.h. durchzunumerieren. Denkbar wäre dabei, eine raumorientierte Meldernumerierung dadurch zu erreichen, daß die Meldeprimärleitung entsprechend verlegt wird. Dies ist aber äußerst aufwendig und unwirtschaftlich, weil eine gesonderte Leitungsführung erforderlich wäre. Darüberhinaus ist zu einem späteren Zeitpunkt eine andere Melderadressierung nicht mehr möglich.However, it is often necessary or desirable to query individual detectors quickly, others only rarely, or, for organizational reasons, for example, not to address the hazard detectors of a primary reporting line according to the order in which they are connected to the primary reporting line. It would be conceivable to achieve a room-oriented detector numbering by laying the primary signal line accordingly. However, this is extremely complex and uneconomical because a separate line would be required. In addition, another detector addressing is no longer possible at a later point in time.
Aufgabe der Erfindung ist es daher, bei einer Gefahrenmeldeanlage, die nach dem Kettensynchronisationsprinzip arbeitet, ein Verfahren für die Adressierung der einzelnen Melder einer Melderprimärleitung anzugeben, welches es gestattet, ohne Adresseinstellung im Melder bzw. in der Fassung die Melder frei wählbar, beispielsweise nach organisatorischen Gesichtspunkten, zu adressieren und abzufragen.The object of the invention is therefore to provide a method for addressing the individual detectors of a primary detector line in a hazard detection system which operates according to the chain synchronization principle, which allows the detectors to be freely selected, for example according to organizational ones, without address setting in the detector or in the version Aspects, to address and query.
Diese Aufgabe wird bei einer eingangs beschriebenen Gefahrenmeldeanlage mit dem erfindungsgemäßen Verfahren dadurch gelöst, daß in jedem Gefahrenmelder ein Adressenspeicher vorgesehen ist, in den in einer Initialisierungsphase von der Zentrale aus eine individuelle bzw. organisatorische Melderadresse eingeschrieben wird, die anschließend für den Betrieb der Gefahrenmeldeanlage verwendet wird, daß in jeder Melderfassung für die schaltbare Leitungsader eine elektrische Verbindung herstellbar ist, wenn kein Gefahrenmelder in der Melderfassung steckt, daß mit der Inbetriebnahme der Gefahrenmeldeanlage (Initialisierungsphase) für jede Meldeprimärleitung eine automatische Adressenvergabe durch die Reihenfolge der Bestückung der Melderfassungen mit Gefahrenmeldern durchgeführt wird, daß in der Zentrale dem ersteingesteckten Gefahrenmelder eine erste physikalische Adresse zugeordnet und gespeichert wird, daß anschließend von der Zentrale aus der betreffende Gefahrenmelder nach seiner organisatorischen Melderadresse gefragt wird, daß die Zentrale bei fehlender organisatorischer Melderadresse dem betreffenden Gefahrenmelder eine erste organisatorische Melderadresse zuordnet und zu diesem überträgt, wo sie in einem nicht flüchtigen Speicher eingeschrieben wird, daß dem zweiteingesetzten Gefahrenmelder eine zweite physikalische Adresse zugeordnet und anschließend eine zweite organisatorische Melderadresse zugeordnet und eingeschrieben wird, daß dieser Vorgang solange durchgeführt wird, bis die jeweiligen Melderprimärleitungen mit sämtlichen Gefahrenmeldern bestückt und mit organisatorischen Melderadressen versorgt sind, und daß anschließend die jeweilige Meldeprimärleitung von dem Initialisierungszustand in den Betriebszustand geschaltet wird.This object is achieved in a hazard detection system described in the introduction with the method according to the invention in that an address memory is provided in each hazard detector, in which an individual or organizational detector address is written in from the control center in an initialization phase, which address is then used for the operation of the hazard detection system will be that an electrical connection can be made in each detector for the switchable cable core if there is no danger detector in the detector is that with the commissioning of the hazard alarm system (initialization phase) for each primary alarm line an automatic address assignment is carried out by the order of equipping the detectors with hazard detectors, that a first physical address is assigned and stored in the control center to the first plugged-in hazard detector, which is then assigned by the control center from the hazard detector concerned, it is asked for its organizational detector address, that the control center, in the absence of an organizational detector address, assigns and transmits a first organizational detector address to the relevant hazard detector, where it is written into a non-volatile memory, that a second physical address is assigned to the second hazard detector used and then a second organizational detector address is assigned and registered so that this process is carried out until the respective detector primary lines are equipped with all hazard detectors and are supplied with organizational detector addresses, and that the respective primary signal line is then switched from the initialization state to the operating state.
Es weist also jeder Melder einen Speicher auf, der von der Zentrale bei einer speziellen Initialisierung mit einer individuellen (organisatorischen) Adresse und mit eventuellen Zusatzdaten versorgt wird. Dazu enthält die Zentrale eine gespeicherte Zuordnungstabelle, die jeder durch die Kettensynchronisation ermittelten physikalischen Melderadresse eine organisatorische Melderadresse zuordnet. Diese Tabelle wird der Zentrale entweder getrennt eingegeben, oder ohne solche Eingabe derart hergestellt, daß mit der Reihenfolge der Melderbestückung automatisch die Zuordnung erfolgt.Each detector therefore has a memory, which the control center supplies with a special (initialization) with an individual (organizational) address and any additional data. For this purpose, the control center contains a stored assignment table which assigns an organizational detector address to each physical detector address determined by the chain synchronization. This table is either entered separately at the control center, or is produced without such an entry that the assignment takes place automatically with the order of the detector.
Mit dem erfindungsgemäßen Verfahren ist es möglich, daß Gefahrenmelder, die nach dem Kettensynchronsisationsverfahren abgefragt werden, bei beliebiger Leitungsführung und ohne Versorgung in der Zentrale und ohne Adresseinstellung im Melder bzw. in der Melderfassung mit einer organisatorischen Melderadresse automatisch versehen werden. Dabei erfolgt die automatische Adressenvergabe in der Initialisierungsphase der Gefahrenmeldeanlage durch die Reihenfolge der Bestückung der Melderfassungen einer Meldeprimärleitung mit den einzelnen Gefahrenmeldern. Hierbei braucht die genaue Leitungsführung und damit die physikalische Melderadresse dem Bediener bzw. dem Inbetriebnehmer der Gefahrenmeldeanlage nicht bekannt zu sein.With the method according to the invention, it is possible that hazard detectors, which are queried according to the chain synchronization method, are automatically provided with an organizational detector address with any line routing and without supply in the control center and without address setting in the detector or in the detector detection. In the initialization phase of the hazard alarm system, the addresses are assigned automatically by the order in which the detectors of a primary alarm line are equipped with the individual hazard alarms. The operator does not need to know the exact cable routing and therefore the physical detector address or the person commissioning the hazard detection system.
Vorteile und weitere Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen und der folgenden Beschreibung des erfindungsgemäßen Verfahrens, das anhand von Zeichnungen erläutert wird. Dabei zeigenAdvantages and further refinements of the invention result from the subclaims and the following description of the method according to the invention, which is explained with reference to drawings. Show
Fig. 1 bis 5 beispielhaft eine Zentrale mit einer Meldeprimärleitung, an die eine Vielzahl von Gefahrenmeldern mit unterschiedlichen physikalischen Melderadressen und organisatorischen Melderadressen angeschlossen sind.1 to 5 an example of a control center with a primary reporting line, to which a large number of hazard detectors with different physical detector addresses and organizational detector addresses are connected.
In Fig. 1 ist eine Zentrale Z mit einer Meldeprimärleitung ML mit den Meldern M1 bis Mn gezeigt, denen auch die physikalischen Adressen PHA 01 bis n zugeordnet sind. Aus organisatorischen Gründen sollen nun die Melderadressen den Raumnummern RNr entsprechen, die jedoch nicht den physikalischen Melderadressen PHA entsprechen. Eine derartige Raumorientierung wäre durchführbar, indem man beispielsweise in der Gefahrenmeldezentrale den physikalischen Melderadressen PHA, die bekannt sind, durch Eingabe in den Datenspeicher der Zentrale die organisatorische Adresse ORA zuordnet. Diese manuelle Eingabe erfordert einen hohen Zeitaufwand und außerordentliche Sorgfalt.1 shows a control center Z with a primary signal line ML with the detectors M1 to Mn, to which the physical addresses PHA 01 to n are also assigned. For organizational reasons, the detector addresses should now correspond to room number RNr, which, however, do not correspond to the physical detector addresses PHA. Such a spatial orientation would be feasible, for example, by assigning the organizational address ORA to the physical detector addresses PHA, which are known, by entering them into the data memory of the control center. This manual entry requires a lot of time and extraordinary care.
Bei dem erfindungsgemäßen Verfahren erfolgt die organisatorische Melderadressenvergabe automatisch mit der Reihenfolge der Melderbestückung. In dem in Fig.2 gezeigt Beispiel wird nun davon ausgegangen, daß eine solche Meldeprimärleitung ML neu in Betrieb genommen wird. Dafür sind alle Melderfassungen MF vorerst unbestückt. Bei dem bekannten Kettensynchronisationsverfahren wird eine Ader der Meldeprimärleitung ML (z.B. b-Ader) durch einen Schalter im Melder durchgeschaltet. Bei nicht mit Meldern bestückten Fassungen ist die Leitung somit zwischen den Fassungsklemmen 4 und 5 immer unterbrochen. Daher ist für das erfindungsgemäße Verfahren vorgesehen, daß die nicht mit Meldern bestückten Fassungen MF eine elektrische Verbindung zwischen diesen beiden Klemmen 4 und 5 aufweisen. Diese kann beispielsweise dadurch hergestellt werden, daß ein eingesteckter Fassungsdeckel die Klemmen 4 und 5 miteinander verbindet. In vorteilhafter Weise kann ein Schalter FS in der Fassung vorgesehen sein, der automatisch geöffnet wird, wenn der Melder gesteckt wird.In the method according to the invention, the organization of the detector address assignment takes place automatically with the sequence of the detector population. In the example shown in FIG. 2, it is now assumed that such a primary signal line ML is put into operation again. For this purpose, all MF detector sockets are initially empty. In the known chain synchronization method, one wire of the signaling primary line ML (e.g. b wire) is switched through by a switch in the detector. If sockets are not equipped with detectors, the line between
Das erfindungsgemäße Verfahren weist folgende Schritte auf. Über eine entsprechende Eingabe, beispielsweise Schalter oder Befehl in der Zentrale Z, wird die Meldeprimärleitung ML in den Initialisierungszustand versetzt. Entsprechend der Fig. 3 wird zuerst der Melder M1, der die organisatorische Melderadresse ORA 01 erhalten soll, eingesetzt. Die Zentrale Z erkennt einen Melder M1, da alle vorhergehenden Fassungen MF durch die Kontakte FS durchverbunden sind, und vergibt diesem die physikalische Melderadresse PHA 01. Anschließend fragt sie den Melder M1 ab, ob er bereits mit einer organisatorischen Adresse ORA versehen wurde. Da der neu eingesetzte Melder noch keine organisatorische Adresse aufweist, bekommt er von der Zentrale Z die organisatorische Melderadresse ORA 01 zugeordnet, die daraufhin von der Zentrale Z zum Melder M1 übertragen und dort nicht flüchtig gespeichert wird. Die organisatorische Melderadresse ORA 01 wird dabei in der Zentrale zur physikalischen Adresse zugeordnet und ebenfalls gespeichert.The method according to the invention has the following steps. The primary signal line ML is set to the initialization state by means of an appropriate input, for example a switch or command in the central station Z. According to FIG. 3, the detector M1, which is to receive the organizational detector address ORA 01, is used first. The control center Z recognizes a detector M1, since all previous versions MF are connected through the contacts FS, and assigns the physical detector address PHA 01 to it. Subsequently, it asks the detector M1 whether it has already been provided with an organizational address ORA. Since the newly inserted detector does not yet have an organizational address, the central Z assigns it the organizational detector address ORA 01, which is then transmitted from the central Z to the detector M1 and is not stored there in a volatile manner. The organizational detector address ORA 01 is assigned to the physical address in the control center and also saved.
In vorteilhafter Weise kann der Abschluß dieses Adressierens quittiert werden, beispielsweise in der Zentrale und darüber hinaus auch beim eingesteckten Melder, indem die dort angebrachte Melderanzeige blinkt. Daraufhin wird - wie in Fig. 4 gezeigt - der Melder M2, der die organisatorische Adresse ORA2 erhalten soll, gesteckt. Jetzt erkennt die Zentrale Z zwei Melder M1 und M2, denen sie entsprechend ihrer Reihenfolge nach dem Kettensynchronisationsprinzip die physikalischen Adressen PHA 01 und 02 zuordnet. Anschließend prüft sie, ob beide Melder M1, M2 schon mit organisatorischen Adressen ORA versorgt wurden. Im gezeigten Beispiel wurde der Melder M1 mit der organisatorischen Adresse ORA 01 vorher schon versorgt, dem neu gesteckten Melder M2 wird die organisatorische Adresse ORA 02 von der Zentrale Z zugeordnet, gespeichert und auch übertragen.The completion of this addressing can advantageously be acknowledged, for example in the control center and, moreover, also when the detector is plugged in, by the detector indicator attached there flashing. Thereupon, as shown in FIG. 4, the detector M2, which is to receive the organizational address ORA2, is inserted. The control center Z now recognizes two detectors M1 and M2, to which it assigns the physical addresses PHA 01 and 02 according to their sequence according to the chain synchronization principle. It then checks whether both detectors M1, M2 have already been supplied with organizational addresses ORA. In the example shown, the detector M1 has already been supplied with the organizational address ORA 01, the organizational address ORA 02 is assigned to the newly inserted detector M2, stored and also transmitted.
Als nächster Schritt ist in Fig.5 noch gezeigt, daß ein dritter Melder M3 eingesteckt wird. Den drei erkannten Meldern M1 bis M3 ordnet die Zentrale Z die physikalischen Melderadressen PHA 01 bis 03 zu. Da der letzte eingesteckte Melder M3 vor den bereits vorhandenen Meldern M1 und M2 eingefügt wurde, verschieben sich nun alle physikalischen Melderadressen PHA. Die Zentrale Z prüft wieder, wie vorher beschrieben, ob die Melder M1 bis M3 bereits mit organisatorischen Adressen ORA versorgt wurden. Bei dem Melder M3 mit der physikalischen Adresse PHA 01 ist dies noch nicht der Fall, deshalb wird ihm die organisatorische Adresse ORA 3 gegeben. In gleicher Weise werden alle übrigen Melder in der gewünschten organisatorischen Reihenfolge in die Linie ML eingefügt und damit automatisch versorgt, bis der gewünschte - in diesem Beispiel gem. Fig.1 - gezeigte Zustand erreicht ist.As the next step it is shown in FIG. 5 that a third detector M3 is inserted. The central station Z assigns the three detected detectors M1 to M3 to the physical detector addresses PHA 01 to 03. Since the last inserted detector M3 was inserted before the existing detectors M1 and M2, all physical detector addresses PHA are now shifted. The control center Z checks again, as previously described, whether the detectors M1 to M3 have already been supplied with organizational addresses ORA. This is not yet the case with detector M3 with the physical address PHA 01, which is why it is given the organizational address ORA 3. In the same way, all other detectors are inserted into the ML line in the desired organizational order and are thus automatically supplied until the desired one - in this example according to Fig.1 - shown state is reached.
Nach Hinzufügen eines neuen Melders ergeben sich - wie ersichtlich - andere Zusammenhänge zwischen den physikalischen und organisatorischen Melderadressen, die von der Zentrale automatisch laufend aktualisiert und gespeichert werden.After adding a new detector, as can be seen, there are other relationships between the physical and organizational detector addresses, which are automatically updated and saved by the control center.
Die den Meldern einmal zugeordneten organisatorischen Adressen bleiben dabei unverändert erhalten. Nach vollständiger Bestückung der Meldeprimärleitung wird diese in der Zentrale scharfgeschaltet, d.h. sie wird in den normalen Betriebszustand geschaltet. Nun können die Melder entweder nach dem Kettensynchronisationsverfahren bekannterweise ständig abgefragt und ihre Daten zur Zentrale übertragen werden. Dabei ist eine Adressenübertragung nicht nötig, da jeder Melder aufgrund seiner physikalischen Adresse eindeutig identifizierbar ist. Über die in der Zentrale hinterlegten zugeordneten organisatorischen Adressen können für die weitere Verarbeitung die jeweils erforderliche organisatorische Adresse ausgewählt werden und damit die entsprechenden Melder gezielt angesprochen werden. In bekannter Weise wird auch schon in der Initialisierungsphase die Anzahl der angeschlossenen Melder festgestellt und abgespeichert. Würde beispielsweise jemand einen Melder entfernen, so würde die nicht bestückte Melderfassung die Leitung selbsttätig durchverbinden. Die Zentrale würde dabei feststellen, daß sich die Anzahl der Melder verringert hat. Sie kann nun automatisch, ähnlich wie bei der Initialisierung einerseits feststellen, welcher Melder fehlt, andererseits eine neue Zuordnung zwischen den physikalischen und organisatorischen Melderadressen generieren. Danach ist weiterhin der Betrieb aller noch vorhandenen Melder auf der Linie in vollem Umfang möglich. Darüber hinaus kann die Zentrale das Fehlen der Melder auch sofort als Störung oder Sabotage erkennen und anzeigen und dabei dennoch die noch vorhandenen Melder im Betriebszustand weiterhin zyklisch abfragen.The organizational addresses assigned to the detectors remain unchanged. After the primary primary line has been fully equipped, it is armed in the control center, i.e. it is switched to the normal operating state. Now, as is known, the detectors can either be continuously queried using the chain synchronization method and their data transmitted to the control center. An address transfer is not necessary because each detector can be clearly identified based on its physical address. Using the assigned organizational addresses stored in the head office, the required organizational address can be selected for further processing and the relevant detectors can thus be specifically addressed. In a known manner, the number of connected detectors is determined and stored even in the initialization phase. If, for example, someone removed a detector, the non-equipped detector socket would automatically connect the line. The control center would find that the number of detectors has decreased. Similar to the initialization, you can now automatically determine which detector is missing on the one hand and generate a new assignment between the physical and organizational detector addresses on the other. After that, the operation of all existing detectors on the line is still fully possible. In addition, the control panel can immediately recognize and display the absence of the detectors as a malfunction or sabotage, while still cyclically polling the detectors that are still in operation.
In einer weiteren Ausgestaltung des erfindungsgemäßen Verfahrens kann das Prinzip der Kettensynchronisation nur zur erfindungsgemäßen Adressenfestlegung benutzt werden, während die Gefahrenmelder betriebsmäßig ihre Daten nach einem anderen Verfahren zur Zentrale übertragen können. Dabei können beispielsweise die Schalttransistoren in den Gefahrenmeldern ständig durchgeschaltet bleiben, so daß alle Melder parallel an der Meldelinie angeschlossen sind. Sie können nun von der Zentrale her über die in den Meldern hinterlegten organisatorischen Adressen in beliebiger Reihenfolge und in beliebigen Zeitabständen abgefragt werden und ihre Information zur Zentrale übertragen. In gleicher Weise ist es auch möglich, daß sich die Melder selbständig melden, wenn sie Informationen zu übergeben haben und dann zur Identifizierung ihre organisatorische, im Melder gespeicherte Adresse mit übertragen.In a further embodiment of the method according to the invention, the principle of chain synchronization can only be used to determine the address according to the invention, while the hazard detectors can transmit their data to the control center by another method. For example, the switching transistors in the hazard detectors remain switched through so that all detectors are connected in parallel to the detection line. You can now be queried from the control center using the organizational addresses stored in the detectors in any order and at any time interval and transfer their information to the control center. In the same way, it is also possible for the detectors to report independently when they have information to transfer and then to transmit their organizational address stored in the detector for identification.
Mit dem erfindungsgemäßen Verfahren kann auch bei einer bereits voll mit Meldern bestückten Meldeprimärleitung eine organisatorische Melderadresse dadurch vergeben werden, daß durch Auslösen der Melder (vor Ort) die organisatorische Adressenvergabe erfolgt. Der oben beschriebene Vorgang ist dann voll auf diesen Vorgang übertragbar, wenn statt dem Einsetzen eines Melders der entsprechende Melder, beispielsweise durch Besprühen mit Rauch, ausgelöst wird.With the method according to the invention, even in the case of a primary primary line that is already fully equipped with detectors, an organizational detector address can be assigned by triggering the detectors (on site) to assign the organizational addresses. The process described above can then be fully transferred to this process if, instead of using a detector, the corresponding detector is triggered, for example by spraying with smoke.
Das erfindungsgemäße Adressierverfahren weist eine Reihe von Vorteilen auf. Eine einfache Vergabe der organisatorischen Adressen ist im Rahmen von ohnehin durchzuführenden Tätigkeiten, z.B. Melderstecken oder Melderauslösen, möglich, ohne dabei die tatsächliche Leitungsführung berücksichtigen zu müssen oder davon Kenntnis zu haben. Eine entsprechende Versorgung in der Zentrale, d.h. ein zusätzlicher Arbeitsgang und die damit verbundenen Fehlerquellen entfallen.The addressing method according to the invention has a number of advantages. A simple assignment of the organizational addresses is necessary in the context of activities to be carried out anyway, e.g. Detector plugging or triggering of detectors possible without having to take the actual cable routing into account or being aware of it. A corresponding supply in the head office, i.e. an additional operation and the associated sources of error are eliminated.
Für die Adresseinstellung ist bei diesem Verfahren kein mechanischer und technischer Aufwand nötig, wie eine Reihe von Schaltern zu betätigen, Bedienfeld mit Adressnummern einschreiben oder Lötbrücken herzustellen. Es sind auch keine besonderen Hardware-Elemente notwendig.This method does not require any mechanical or technical effort to set the address, such as actuating a series of switches, writing in the control panel with address numbers or making solder bridges. No special hardware elements are necessary either.
Beim Entfernen eines Melders oder bei einem Melderdefekt, z.B. weil der schadhafte Melder ständig geschlossen bleibt, bleiben alle anderen Melder einer Meldeprimärleitung voll funktionsfähig. Muß der defekte Melder ausgetauscht werden, so muß nur dieser neue Melder mit der organisatorischen Melderadresse neu versorgt werden, alle anderen Adressen bleiben unverändert erhalten. Diese automatische Adressensvergabe weist einen hohen Grad von Zuverlässigkeit auf, weil ein mühsames Eingeben einzelner Adressen per Hand entfällt.When a detector is removed or a detector defect, e.g. Because the defective detector remains closed at all times, all other detectors on a primary reporting line remain fully functional. If the defective detector has to be replaced, only this new detector has to be supplied with the organizational detector address, all other addresses remain unchanged. This automatic address assignment has a high degree of reliability because there is no need to manually enter individual addresses.
Claims (9)

that a first physical address (PHA 01) is assigned to the first alarm (M1) to be inserted and stored in the central unit (Z),
that the alarm (M1) in question is then interrogated from the central unit (Z) to ascertain its organizational alarm address (ORA),
that in the absence of an organizational alarm address (ORA 01), the central unit assigns a first organizational alarm address (ORA 01) to the alarm (M1) in question and transmits the said address to the latter if the address has been written into a non-volatile memory, that a second physical address (PHA 02) is assigned to the second alarm (M2) to be used, to which there is then assigned and written a second organizational alarm address (ORA2),
that this process is carried out until the respective primary alarm line (ML) has been equipped with all the alarms (M1 to Mn) and been supplied with organizational alarm addresses (ORA 01 to n) and that the respective primary alarm line (ML) is subsequently switched from the initialization condition to the operating condition. - Method according to Claim 1,
characterized in that during operation, the organizational alarm address is used in conjunction with chain synchronization. - Method according to Claim 1,
characterized in that chain synchronization is dispensed with during operation, the switching devices in the alarms remaining constantly switched through and the alarms being invoked via the stored organizational address. - Method according to one of Claims 1 to 3,
characterized in that electrical connection is established in the alarm mount (MF) by means of a mount lid. - Method according to one of Claims 1 to 3,
characterized in that the electrical connection in the alarm mount (MF) is established automatically by means of a switch (FS) which can be actuated by the alarm. - Method according to Claim 1,
characterized in that successful storage of the organizational alarm address (ORA) is acknowledged. - Method according to Claim 6,
characterized in that acknowledgement is displayed at the alarm (M) in question. - Method according to one of the preceding claims, characterized in that the number (n) of alarms (M) connected per primary alarm line (ML) is determined and stored in the initialization condition in the central unit (Z), and that the number (n) of alarms is examined each time a primary alarm line (ML) is interrogated in the operating condition.
- Method according to one of the preceding claims, characterized in that organizational distribution of alarm addresses is carried out via the order in which the already mounted alarms are actuated instead of using the mounting of a primary line with alarms.
