Zweck der Erfindung ist es, eine Anordnung der vorgenannten Art derart weiterzubilden, daß deren Zuverlässigkeit weiter verbessert wird.The purpose of the invention is to develop an arrangement of the aforementioned type in such a way that its reliability is further improved.
Bei den Schaltungsanordnungen für die UHF-Sender-Schaltungen zur Anwendung bei den einleitend zitierten Anlagen, werden vorteilhaft sogenannte OFW-Bauelemente (OFW = Oberflächenwellen) als Resonatoren für die Oszillatoren verwendet. Diese Bauelemente zeichnen sich durch eine Reihe von vorteilhaften Eigenschaften aus, die für die hier verwendeten Oszillatoren im UHF-Bereich zweckmäßig nutzbar sind.In the circuit arrangements for the UHF transmitter circuits for use in the systems cited in the introduction, what are known as SAW components (SAW = surface waves) are advantageously used as resonators for the oscillators. These components are distinguished by a number of advantageous properties which can be expediently used for the oscillators used here in the UHF range.
So erlauben diese Bauelemente die Herstellung von schmalbandigen Oszillatoren mit einer je nach der Größenordnung ihrer Frequenz wechselnden Güte zwischen etwa 7000 und 20000.These components allow the production of narrow-band oscillators with a quality that varies depending on the magnitude of their frequency between approximately 7,000 and 20,000.
Diese Oszillatoren schwingen mit ihrer Grundwellenfrequenz etwa in der Größenordnung zwischen 200 MHz und 1 GHz.These oscillators oscillate with their fundamental wave frequency in the order of magnitude between 200 MHz and 1 GHz.
Sie werden vielfach als schmalbandige, frequenzbestimmende Elemente im Rückkopplungszweig von Verstärkern eingesetzt und zeigen sehr gute Rauscheigenschaften.They are often used as narrow-band, frequency-determining elements in the feedback branch of amplifiers and show very good noise properties.
Durch eine entsprechende Bemessung und Auslegung der OFW-Bauelemente lassen diese sich auf eine bestimmte Eigenfrequenz in der erwünschten Größenordnung festlegen.By appropriate dimensioning and design of the SAW components, these can be set to a specific natural frequency in the desired order of magnitude.
Für die Verbrauchsverteilereinrichtungen, so Heizkosten- oder Warmwasserkostenverteiler bei den Anlagen nach der Erfindung, wird eine einheitliche Sendefrequenz verwendet. Über diese Sendefrequenz werden sämtliche Daten, die zur Kennzeichnung für den betreffenden Verbrauchsverteiler von Interesse sind, an eine nachgeordnete Zentralstelle auf dem Funkwege übertragen. Von der Schaltungsanordnung eines jeden UHF-Senders einer Verbrauchsverteilereinrichtung wird bevorzugt eine Trägerwelle im Bereich der vorgegebenen Frequenz ausgestrahlt, welche im Rhythmus der Sequenz des Signalcodes der zu übertragenden Daten frequenzmoduliert wird.A uniform transmission frequency is used for the consumption distribution devices, such as heating cost or hot water cost allocators in the systems according to the invention. Via this transmission frequency, all data that are of interest for identification for the relevant distribution board are transmitted to a subordinate central point on the radio path. A carrier wave in the range of the predetermined frequency is preferably emitted by the circuit arrangement of each UHF transmitter of a consumption distribution device and is frequency-modulated in the rhythm of the sequence of the signal code of the data to be transmitted.
Trotz der einheitlichen Festlegung einer gemeinsamen Sendefrequenz und trotz der weitgehenden Frequenzkonstanz der verwendeten OFW-Bauelemente als Resonatoren in den Senderschaltungen, sind gewisse Frequenzabweichungen, insbesondere unter Einfluß der Temperaturschwanungen, nicht ganz vermeidbar.
Um sicherzustellen, daß trotz der Frequenzabweichungen alle UHF-Sender und damit alle damit bestückten Verbrauchsverteilereinrichtungen durch die vorteilhaft als Superheterodyne-Schaltung ausgebildete Empfängerschaltung erfaßt werden können, ist eine gewisse Bandbreite des Empfängereinganges der Empfängerschaltung unverzichtbar.Despite the uniform definition of a common transmission frequency and despite the largely constant frequency of the SAW components used as resonators in the transmitter circuits, there are certain frequency deviations, in particular under the influence of temperature fluctuations, not entirely avoidable.
In order to ensure that, despite the frequency deviations, all UHF transmitters and thus all the consumption distribution devices equipped with them can be detected by the receiver circuit, which is advantageously designed as a superheterodyne circuit, a certain bandwidth of the receiver input of the receiver circuit is indispensable.
Damit werden durch den Empfänger jedoch alle in diesem Empfangsbereich auftretenden Störsignale und Fremdimpulse mit aufgenommen, welche zu einer Trübung der von einer Verbrauchsverteilereinrichtung übermittelten Meßsignale führen.In this way, however, all interference signals and external pulses occurring in this reception area are recorded by the receiver, which lead to turbidity in the measurement signals transmitted by a consumption distribution device.
Dies hat zur Folge, daß eintreffende Meßsignale durch die Prüfschaltung der dem Empfänger zugeordneten Zentralstelle nur bedingt als richtig erkannt werden können. Es wird von Fall zu Fall der Empfang mehrerer Signalfolgen und deren Überprüfung notwendig werden, um die gezielte Ablesung einer bestimmten Verbrauchsverteilereinrichtung vornehmen zu können. Die Betriebssicherheit der Signalübertragung ist somit durch den erforderlichen breitbandigen Eingang des Empfängers gemindert.The result of this is that incoming measurement signals can only be partially recognized as correct by the test circuit of the central point assigned to the receiver. From case to case, it will be necessary to receive and check several signal sequences in order to be able to read a specific consumption distribution device in a targeted manner. The operational reliability of the signal transmission is thus reduced by the required broadband input of the receiver.
Es ist Aufgabe der Erfindung, die Anordnung nach der Patentanmeldung so weiterzubilden, daß eine möglichst ungestörte Übertragung der Meßsignale von den Verbrauchsverteilereinrichtungen zum Empfänger erfolgen kann.It is an object of the invention to further develop the arrangement according to the patent application in such a way that the measurement signals can be transmitted as undisturbed as possible from the consumption distribution devices to the receiver.
Die Erfindung löst die gestellte Aufgabe dadurch, daß der Eingang der Empfängerschaltung (6) relativ breitbandig ausgebildet ist und daß dieser (6) eine schmalbandig (df) wirkende Scanner-Schaltung (3) zugeordnet ist, welche etwa über dem Bereich der Bandbreite (Df) des Einganges der Empfängerschaltung (6) wirksam ist.The invention achieves the object in that the input of the receiver circuit (6) is designed to be relatively broadband and that this (6) is associated with a narrowband (df) scanner circuit (3) which is approximately above the range of bandwidth (Df ) of the input of the receiver circuit (6) is effective.
Eine Weiterbildung der Erfindung wird darin gesehen, daß die Scanner-Schaltung (3) zwingend zusammen mit der Empfängerschaltung (6) wirksam ist und nur gemeinsam mit dieser (6) ein- und ausschaltbar ist.A further development of the invention is seen in the fact that the scanner circuit (3) is absolutely effective together with the receiver circuit (6) and can only be switched on and off together with the latter (6).
Eine andere mögliche Ausgestaltung der Erfindung wird darin erblickt, daß der Scanner-Schaltung (3) ein UHF-Breitbandverstärker (2) zugeordnet ist.Another possible embodiment of the invention is seen in the fact that the scanner circuit (3) is assigned a UHF broadband amplifier (2).
Schließlich soll eine Ausgestaltung der Erfindung noch darin gesehen werden, daß der UHF-Breitbandverstärker (2) eine nichtlineare Verstärkerkennlinie aufweist, welche vorzugsweise etwa quadratisch ist.Finally, an embodiment of the invention should be seen in that the UHF broadband amplifier (2) has a nonlinear amplifier characteristic, which is preferably approximately square.
Die Erfindung hat Vorteile aufzuweisen; diese bestehen z.B. darin, daß die wirksame Breite des vom Scanner in jedem Augenblick schmalbandig überdeckten Frequenzbereiches im wesentlichen immer konstant bleibt.The invention has advantages; these consist e.g. in that the effective width of the frequency range covered by the scanner at every moment in the narrow band essentially remains constant.
Die Erfindung ist in der nachstehenden Beschreibung in Form eines Ausführungsbeispieles erläutert und in den beigegebenen Zeichnungen im einzelnen dargestellt.The invention is explained in the following description in the form of an embodiment and shown in detail in the accompanying drawings.

Aus Figur 1 ist ersichtlich, daß die Empfangsantenne 1 an den Eingang eines UHF-Breitbandverstärkers 2 angeschaltet ist, welcher seinerseits dem gemäß der Erfindung zugeordneten Scanner 3 vorgeschaltet ist.It can be seen from FIG. 1 that the receiving antenna 1 is connected to the input of a UHF broadband amplifier 2, which in turn is connected upstream of the scanner 3 assigned according to the invention.
Der Breitbandverstärker 2 dient zur Anhebung des Signalpegels, der an der Antenne 1 einfallenden Signale von den Sendeantennen 11 der Verbrauchsverteilereinrichtungen 10.
Der Breitbandverstärker 2 hat vorzugsweise eine nichtlineare, insbesondere quadratische Kennlinie, um die einfallenden Signale der Verbrauchsverteilereinrichtung 10 gegenüber dem allgemeinen Störpegel zu begünstigen.The broadband amplifier 2 serves to raise the signal level of the signals arriving at the antenna 1 from the transmitting
The broadband amplifier 2 preferably has a nonlinear, in particular quadratic, characteristic curve in order to favor the incoming signals of the
Der Scanner 3 bewirkt eine fortlaufende schmalbandige (df) Abtastung des Durchlaßbereiches (Df) des Breitbandverstärkers 2 und erreicht dadurch eine Störverminderung des Breitbandbereiches des Verstärkers 2. Der Scanner 3 wird vorteilhaft von einem Mikroprozessor 5 gesteuert, welcher der Schaltungsanordnung nach Figur 1, die die Empfängerschaltung 6 nebst dem Abrechner 7 bis 9 zum Gegenstand hat, gemeinsam ist.The scanner 3 effects a continuous narrowband (df) scanning of the pass band (Df) of the broadband amplifier 2 and thereby achieves interference reduction of the broadband range of the amplifier 2. The scanner 3 is advantageously controlled by a
Die Empfängerschaltung 6 umfaßt ebenso wie der Breitbandverstärker 2 einen breitbandigen (Df) Eingangskreis, welcher eine Dämpfungscharakteristik nach Figur 2 aufweist und dem eine Superheterodyne-Schaltung für Frequenzdemodulation nachgeordnet ist.Like the broadband amplifier 2, the receiver circuit 6 comprises a broadband (Df) input circuit which has an attenuation characteristic according to FIG. 2 and which is followed by a superheterodyne circuit for frequency demodulation.
Die der Empfängerschaltung 6 nachgeordnete Auswerteschaltung 7 befaßt sich mit der Speicherung, Kontrolle und Auswertung der von den Verbrauchsverteilereinrichtungen 10 über deren Antennen 11 auf dem Funkwege übermittelten Meßwerttelegramme.The evaluation circuit 7 downstream of the receiver circuit 6 deals with the storage, control and evaluation of the measured value telegrams transmitted by the
Die von den Verteilereinrichtungen 10 aufsummierten, an diesen selbst angezeigten und über ihre Antennen 11 emittierten Daten stehen in der Auswerteschaltung 7 abrufbereit dem Auswertecomputer 8 zur Verfügung, welcher die Verbrauchsabrechnungen unter Ergänzung sämtlicher für den Verbraucher interessanten und bedeutsamen Daten aufbereitet und diese über den Printer 9 zum Ausdruck bringt.The data added up by the
Sämtliche Baugruppen, soweit diese prozessorgesteuert sind (3 - 9), stehen mit dem gemeinsamen, zentralen Mikroprozessor 5 über einen schematisch angedeutet Bus 15 in Verbindung und - soweit notwendig - auch im Datenaustausch.All modules, insofar as they are processor-controlled (3 - 9), are connected to the common,
Sämtliche von den einzelnen Verbrauchsverteilereinrichtungen 10 nach Figur 1 über deren Antennen 11 ausgestrahlten bzw. übermittelten UHF-Signale werden von der Empfangsantenne 1 erfaßt und vom Scanner 3 störungsbereinigt, der Empfängerschaltung 6 zugeleitet.All UHF signals transmitted or transmitted by the individual
In Figur 2 ist schematisch der Verlauf der Eingangsfämpfung des Breitbandverstärkers 2 bzw. der Empfängerschaltung 6 innerhalb des Frequenzbereiches Df dargestellt. Dieser Frequenzbereich Df gibt den Streubereich des Frequenzbandes der durch OFW-Bauelemente gesteuerten Oszillatoren der UHF-Sender (10) wieder.FIG. 2 schematically shows the course of the input attenuation of the broadband amplifier 2 or of the receiver circuit 6 within the frequency range Df. This frequency range Df reflects the range of the frequency band of the oscillators of the UHF transmitters (10) controlled by SAW components.
Der Scanner 3 stellt einen schmalbandigen, den Frequenzbereich df umfassenden Eingang der insbesondere als Superheterodyne ausgebildeten Empfangsschaltung dar, die mit einer gesteuerten variablen Abstimmung versehen ist, derart, daß der angeschnittene Frequenzbereich df im Breitbandbereich Df abtastend hin- und herwandert.The scanner 3 represents a narrow-band input, which comprises the frequency range df, of the receiving circuit, which is designed in particular as a superheterodyne and which is provided with a controlled variable tuning, in such a way that the cut-off frequency range df scans back and forth in the broadband range Df.
In diesem Bereich Df etwa können die Eigenfrequenzen der Senderoszillatoren der Verbrauchsverteilereinrichtung 10 streuen.In this area Df, for example, the natural frequencies of the transmitter oscillators of the
Dieser Streubereich Df der OFW-Resonatoren der Senderschaltungen wird vor allem bei Heizkosten- und Warmwasserkostenverteilern bedeutsam, wegen der hier auftretenden möglichen hohen Temperaturschwankungen.This scattering range Df of the SAW resonators of the transmitter circuits is particularly important in the case of heat cost and hot water cost allocators, because of the possible high temperature fluctuations that occur here.
Die OFW-Resonatoren sind an und für sich recht frequenzkonstant, bei den in den vorgenannten Anwendungsfällen auftretenden hohen möglichen Temperaturdifferenzen jedoch sind gewisse Frequenzschwankungen der mit OFW-Resonatoren bestückten UHF-Senderschaltungen nicht ganz zu vermeiden.The SAW resonators are inherently quite constant in frequency, but given the high possible temperature differences occurring in the aforementioned applications, certain frequency fluctuations of the UHF transmitter circuits equipped with SAW resonators cannot be completely avoided.
Es ist somit erforderlich, daß der Verstärker 2 sowohl als auch die Empfängerschaltung 6 im Bereich Df durchlässige bzw. breitbandige Eingänge aufweisen.It is therefore necessary that the amplifier 2 as well as the receiver circuit 6 have permeable or broadband inputs in the area Df.
Dieser vergleichsweise breitbandige Durchlaßbereich (Df) wird nun durch den entsprechend bemessenen und ausgelegten Scanner 3 schmalbandig (df) kontinuierlich auf Signaleinfall abgetastet.
Es ist so sichergestellt, daß innerhalb des Durchlaßbereiches (Df) der Eingänge des Verstärkers 2 und der Empfängerschaltung 6, welcher ja etwa dem Streubereich der OFW-Resonatoren der UHF-Senderschaltungen (10) entspricht, eine stetige und störungsmindernde, schmalbandige Überwachung stattfindet.This comparatively broadband passband (Df) is now continuously scanned for signal incidence by the appropriately dimensioned and designed scanner 3 in narrowband (df).
This ensures that within the pass band (Df) of the inputs of the amplifier 2 and the receiver circuit 6, which corresponds approximately to the scattering range of the SAW resonators of the UHF transmitter circuits (10), there is a continuous and interference-reducing, narrowband monitoring.
Scanner 3 und Empfängerschaltung 6 sind stets zwingend gemeinsam in Funktion.Scanner 3 and receiver circuit 6 are always mandatory in function.
Die Breite des Durchlaßbereiches (Df) der Eingänge des Breitbandverstärkers (2) bzw. der Empfängerschaltung (6) wird durch den Betrag der maximal möglichen Frequenzabweichung des OFW-Resonators (10) vom Sollwert bestimmt.The width of the pass band (Df) of the inputs of the broadband amplifier (2) or the receiver circuit (6) is determined by the amount of the maximum possible frequency deviation of the SAW resonator (10) from the target value.
