Abstract

The invention relates to a device for measuring the consumption of gas, water, heat or similar, comprising a measuring mechanism which is connected to a counting mechanism by a gear. These types of devices are known, however the cost of reading the gas, water or heat meter is considerable. In addition, there is a risk of transmission errors. The invention addresses this problem by providing a shaft which is engaged with the counting mechanism or the gear and at whose other end means for providing or controlling a remote display or remote scanner are located.

Description

BESCHREIBUNG DESCRIPTION

Vorrichtung zum Messen des Gas-, Wasser- und Wärmeverbrauchs oder dergleichenDevice for measuring gas, water and heat consumption or the like

Die Erfindung betrifft eine Vorrichtung zum Messen des Gas-, Wasser-, Wärmeverbrauchs oder dergleichen, mit einem Meßwerk, das über ein Getriebe mit einem Zählwerk verbunden ist.The invention relates to a device for measuring gas, water, heat consumption or the like, with a measuring mechanism, which is connected via a gear to a counter.

Derartige Vorrichtungen sind bekannt. Allerdings ist der Aufwand beim Ablesen der Gas-, Wasser- oder Wärmezähler enorm, da zyklisch ein Ableser von Haus zu Haus gehen muß, der die Werte der Zähler erfaßt und an die Auswertestelle zur Rechnungserstellung übermittelt. Zudem besteht hierbei die Gefahr von Übermittlungsfehlern.Such devices are known. However, the effort involved in reading the gas, water or heat meters is enormous, since a meter has to go cyclically from house to house, which records the values of the meters and transmits them to the evaluation point for billing. There is also a risk of transmission errors.

Einer kostengünstigen Übertragung der Verbrauchsdaten durch den Verbraucher an die Auswertestelle steht allerdings die Gefahr einer Manipulation der Verbrauchsdaten entgegen.A cost-effective transmission of the consumption data by the consumer to the evaluation point, however, stands in the way of manipulation of the consumption data.

Der Erfindung liegt daher die Aufgabe zugrunde, die technischen Möglichkeiten von Gas-, Wasser- und Wärmezählern zu erweitern, indem Vorkehrungen für eine Fernübermittlung der durch den jeweiligen Zähler erfaßten Verbrauchsdaten getroffen werden.The invention is therefore based on the object of expanding the technical possibilities of gas, water and heat meters by taking precautions for remote transmission of the consumption data recorded by the respective meter.

Diese Aufgabe wird dadurch gelöst, daß eine Welle vorgesehen ist, die mit dem Zählwerk oder dem Getriebe in Eingriff ist und an deren anderen Ende Mittel zum Durchführen bzw. Kontrollieren einer Fernanzeige bzw. Fernabfrage angeordnet sind.This object is achieved in that a shaft is provided which engages with the counter or the gear and at the other end of which means for carrying out or checking a remote display or remote query are arranged.

Diese Welle, deren Drehzahl der Stelle des Getriebes bzw. des Zählwerkes proportional ist, mit der sie im Eingriff steht, kann entweder direkt zu Zwecken der Fernübertragung der Verbrauchsdaten genutzt werden oder zur Erstellung eines Kontrollcodes, der die Verifizierung der durch den Verbraucher übertragenen Verbrauchsdaten ermöglicht.This shaft, the speed of which is proportional to the position of the gearbox or the counter with which it is engaged, can either be used directly for the purpose of remote transmission of the consumption data or to generate a control code which enables the verification of the consumption data transmitted by the consumer ,

Eine Ausbildung der Erfindung besteht darin, daß am anderen Ende der Welle ein Reedmagnet angeordnet ist, dem ein Reedkontakt mit Fernanzeige oder Fernabfrage zugeordnet ist. Mit einer derartigen Vorrichtung kann ein sogenannter Impulszähler realisiert werden, der durch Fernanzeige oder Fernabfrage von der Auswertestelle auswertbar ist.An embodiment of the invention is that a reed magnet is arranged at the other end of the shaft, to which a reed contact with remote display or remote query is assigned. With such a device, a so-called pulse counter can be implemented, which can be evaluated by remote display or remote query from the evaluation point.

Eine andere Ausbildung besteht darin, daß das andere Ende der Welle mit einem Kontrollcodewerk verbunden ist.Another embodiment is that the other end of the shaft is connected to a control code plant.

Diese Ausbildung der Erfindung, die auch mit der vorstehenden kombiniert sein kann, ermöglicht das Erstellen eines Kontrollcodes, der zu den angezeigten Verbrauchswerten in einer der Auswertestelle bekannten Relation steht und somit eine Kontrolle der vom Verbraucher bzw. dem Impulszähler übermittelten Werte ermöglicht.This embodiment of the invention, which can also be combined with the foregoing, enables the creation of a control code which is related to the displayed consumption values in a relationship known to the evaluation point and thus enables the values transmitted by the consumer or the pulse counter to be checked.

Es ist zweckmäßig, daß das Kontrollcodewerk ein anderes Übersetzungsverhältnis hat als das Zählwerk.It is expedient that the control code plant has a different transmission ratio than the counter.

Dies erschwert das Entschlüsseln des Kontrollcodes.This makes it difficult to decrypt the control code.

Erfindungsgemäß ist vorgesehen, daß das Kontrollcodewerk Zahlen, Buchstaben oder sonstige Symbole anzeigt.According to the invention, it is provided that the control code plant displays numbers, letters or other symbols.

Weiterhin liegt es im Rahmen der Erfindung, daß die Welle mit verschiedenen Rädern des Zählwerkes in Eingriff bringbar ist.Furthermore, it is within the scope of the invention that the shaft can be brought into engagement with various wheels of the counter.

Durch diese Maßnahme wird es möglich, je nach vorliegendem Verbrauch sinnvolle Impulse zu übermitteln, z.B. bei Hauswasserzählern litergenau, bei Industriewasserzählern auf 100 1 genau.This measure makes it possible to transmit meaningful impulses depending on the consumption, e.g. for domestic water meters to the liter, for industrial water meters to 100 1.

Eine Weiterbildung der Erfindung besteht darin, daß das Getriebe zwischen dem Meßwerk und dem Zählwerk ein Magnetgetriebe ist.A further development of the invention is that the gear between the measuring mechanism and the counter is a magnetic gear.

Magnetgetriebe vermeiden viele Nachteile mechanischer Getriebe, insbesondere Reibungsverluste und sind hochgenau. Vorteilhaft ist auch, daß die Welle mit dem Getriebe oder dem Zählwerk über eine Magnetkupplung verbunden ist.Magnetic gears avoid many disadvantages of mechanical gears, in particular friction losses and are highly precise. It is also advantageous that the shaft is connected to the gearbox or the counter via a magnetic coupling.

Ebenso ist es zweckmäßig, daß das andere Ende der Welle mit dem Kontrollcodewerk über eine Magnetkupplung verbunden ist.It is also appropriate that the other end of the shaft is connected to the control code work via a magnetic coupling.

Magnetkupplungen weisen entsprechende Vorteile wie sie oben für Magnetgetriebe beschrieben wurden auf.Magnetic clutches have corresponding advantages as described above for magnetic gears.

Eine vorteilhafte Weiterbildung der Erfindung besteht darin, daß die Vorrichtung in einem Gehäuse angeordnet ist und daß Mittel zum Unkenntlichmachen der Relation zwischen dem Zählerstand des Zählwerkes und dem des Kontrollcodewerkes beim Öffnen des Gehäuses vorgesehen sind.An advantageous development of the invention is that the device is arranged in a housing and that means are provided for making the relationship between the counter reading of the counter and that of the control code mechanism unrecognizable when the housing is opened.

Es ist von Bedeutung, daß beim Öffnen des Gehäuses die Relation zwischen dem Zählerstand des Zählwerkes und dem des Kontrollcodewerkes unkenntlich gemacht wird, da ansonsten die Gefahr einer Manipulation der Verbrauchswerte vor dem Übermitteln an die Auswertestelle gegeben ist.It is important that when the housing is opened, the relationship between the counter reading of the counter and that of the control code plant is made unrecognizable, since otherwise there is a risk of manipulation of the consumption values before transmission to the evaluation point.

Im folgenden wird die Erfindung anhand eines Ausfuhrungsbeispiels beschrieben.The invention is described below with reference to an exemplary embodiment.

Es zeigenShow it

Fig. 1 eine erfindungsgemäße Vorrichtung als Impulszähler,1 shows a device according to the invention as a pulse counter,

Fig. 2 eine erfindungsgemäße Vorrichtung mit einem Kontrollcode.Fig. 2 shows a device according to the invention with a control code.

Fig. 1 zeigt ein Zählwerk 1 eines Gas-, Wasser- oder Wärmezählers, wobei eine Welle 2 vorgesehen ist, die mit dem Zählwerk 1 im Eingriff steht und die an ihrem anderen Ende einen Reedmagneten 3 aufweist. Diesem Reedmagneten 3 ist ein Reedkontakt 4 zugeordnet, welcher über eine Fernabfrage ablesbar ist. Auf diese Weise wird ein fernablesbarer Impulszähler geschaffen. Wie aus Fig. 2 ersichtlich, ist mit dem Zählwerk 1 eines Gas-, Wasser- oder Wärmezählers eine Welle 2 im Eingriff, deren anderes Ende mit einem Kontrollcodewerk 5 im Eingriff steht. Der Aufbau des Kontrollcodewerkes 5 entspricht dem eines Zählwerkes, weist allerdings in der Regel weniger Rollen als ein Zählwerk und vorzugsweise ein anderes Übersetzungsverhältnis als das Zählwerk auf. Die Rollen des Kontrollcodezählwerkes 5 könnnen Zahlen, Buchstaben oder sonstige Symbole aufweisen. Selbstverständlich kann diese Variante auch mit der gemäß Fig. 1 kombiniert werden.1 shows a counter 1 of a gas, water or heat meter, a shaft 2 being provided which is in engagement with the counter 1 and which has a reed magnet 3 at its other end. A reed contact 4 is assigned to this reed magnet 3 and can be read off by remote inquiry. In this way, a remotely readable pulse counter is created. As can be seen from FIG. 2, a shaft 2 is engaged with the counter 1 of a gas, water or heat meter, the other end of which is in engagement with a control code mechanism 5. The structure of the control code plant 5 corresponds to that of a counter, but generally has fewer roles than a counter and preferably a different transmission ratio than the counter. The roles of the control code counter 5 can have numbers, letters or other symbols. Of course, this variant can also be combined with that according to FIG. 1.

Die Welle 2 ist jeweils verschiebbar und vorzugsweise teleskopierbar und kann somit mit unterschiedlichen Rollen des Zählwerkes 1 in Eingriff gebracht werden.The shaft 2 is displaceable and preferably telescopic and can thus be brought into engagement with different roles of the counter 1.

Vorzugsweise ist das Getriebe zwischen Meß- und Zählwerk ein Magnetgetriebe und die Kupplungen zwischen der Welle und dem Zähl- bzw. dem Kontrollcodewerk sind Magnetkupplungen.Preferably, the gear between the measuring and counter is a magnetic gear and the couplings between the shaft and the counter or the control code are magnetic couplings.

Um ein Enschlüsseln des Kontrollcodes durch Demontage zu verhindern, kann vorgesehen sein, daß bei Öffnen des Gehäuses, in dem das Meß- und das Zählwerk angeordnet sind, Teile des Zähl- oder des Kontrollcodewerkes verdreht werden oder sich lösen, was beispielsweise durch Schnapphaken oder andere elastische Elemente realisiert werden kann. In order to prevent decryption of the control code by disassembly, it can be provided that when the housing in which the measuring and counter is arranged is opened, parts of the counter or control code mechanism are rotated or loosened, for example by snap hooks or others elastic elements can be realized.
