Die Erfindung betrifft ein Verfahren zur Übermittlung von mindestens einem Datum, eine Anordnung zur Übermittlung von mindestens einem Datum, ein Computerprogramm sowie ein Computerprogrammprodukt.The invention relates to a method for transmitting at least one datum, an arrangement for transmitting at least one datum, a computer program and a computer program product.

Stand der TechnikState of the art

Bei einer Übermittlung und somit Übertragung von Daten ist vorgesehen, dass diese Daten von mindestens einem Sender gesendet und über ein Übertragungsmedium, bspw. drahtlos mittels elektromagnetischer Wellen, übermittelt und von mindestens einem Empfänger empfangen werden. Falls die Daten über elektromagnetische Wellen übermittelt werden, sollte bekannt sein, über welche Übermittlungsfrequenz die Übermittlung erfolgt. In der Regel ist dem mindestens einen Empfänger bekannt, auf welcher Frequenz der mindestens eine Sender die Daten sendet, so dass der mindestens eine Empfänger ein Empfangsmodul zum Empfangen der Daten auf die Frequenz des Senders einstellen kann. Bei einer Anwendung können die Daten während eines Betriebs einer sog. Hausnotrufanlage übermittelt werden.In a transmission and thus transmission of data, it is provided that this data is transmitted by at least one transmitter and transmitted via a transmission medium, for example wirelessly by means of electromagnetic waves, and received by at least one receiver. If the data is transmitted via electromagnetic waves, it should be known which transmission frequency the transmission takes place. In general, the at least one receiver is known on which frequency the at least one transmitter transmits the data, so that the at least one receiver can set a receiving module for receiving the data to the frequency of the transmitter. In one application, the data may be transmitted during operation of a so-called home emergency call system.

Ein Verfahren zum Betrieb einer derartigen Hausnotrufanlage ist in der Druckschrift DE 197 34 594 A1 beschrieben. Hierbei weist ein Teilnehmerendgerät eine Empfangseinrichtung für den Empfang eines Notsignals und eine Schnittstelleneinrichtung für die Abgabe von Notrufsignalen über einen Netzanschluß eines Telefonnetzes auf. Dabei empfängt das Teilnehmerendgerät in ersten zeitlichen Abständen Teilnehmerzustände, die eine Aufnahmeeinrichtung wiederholt erfasst hat. Außerdem sendet dieses Teilnehmerendgerät in zweiten zeitlichen Abständen aus den Teilnehmerzustandsdaten abgeleitete Daten über den Netzanschluss des Telefonnetzes an eine Netzteilnehmerstation.A method for operating such a house emergency call system is in the document DE 197 34 594 A1 described. In this case, a subscriber terminal has a receiving device for the reception of an emergency signal and an interface device for the delivery of emergency call signals via a network connection of a telephone network. In this case, the subscriber terminal receives at first time intervals subscriber states, which has repeatedly recorded a receiving device. In addition, this subscriber terminal sends data derived from the subscriber state data via the network connection of the telephone network to a network subscriber station at second time intervals.

Eine weitere Hausnotrufanlage ist aus der Druckschrift DE 196 46 091 A1 bekannt. Diese Hausnotrufanlage weist einen Notrufgeber und ein zur Alarmierung einer Zentrale dienendes Teilnehmerendgerät auf. Hierbei ist ein Bewegungsmelder zur Meldung eines Alarms an das Teilnehmerendgerät vorgesehen. Ein Umschalter ist zur Umschaltung des Teilnehmerendgeräts auf eine Betriebsweise mit einer Einbruchmeldefunktion vorgesehen, so dass aufgrund einer etwaigen Meldung des Bewegungsmelders ein Alarm gegeben werden kann. Weiterhin ist innerhalb der Hausnotrufanlage eine Einrichtung zum Scharf - bzw. Unscharfschalten der Einbruchmeldefunktion vorgesehen.Another house emergency call system is from the publication DE 196 46 091 A1 known. This home emergency call system has an emergency call station and a subscriber terminal serving to alert a center. In this case, a motion detector is provided for reporting an alarm to the subscriber terminal. A switch is provided for switching the user terminal to a mode of operation with a burglar alarm function, so that an alarm can be given due to a possible message of the motion detector. Furthermore, a device for arming or disarming the burglar alarm function is provided within the home emergency call system.

Offenbarung der ErfindungDisclosure of the invention

Die Erfindung betrifft ein Verfahren zur Übermittlung und somit zur Übertragung von mindestens einem Datum, bei dem das mindestens eine Datum auf einer Nominalfrequenz eines Senders von diesem Sender gesendet wird, und bei dem das mindestens eine Datum mindestens einmal unter einem ersten Frequenzversatz zu der Nominalfrequenz von dem Sender gesendet wird.The invention relates to a method for transmitting and thus transmitting at least one datum, in which the at least one datum is transmitted at a nominal frequency of a transmitter from this transmitter, and wherein the at least one datum at least once at a first frequency offset to the nominal frequency of the transmitter is sent.

Somit kann das mindestens eine Datum redundant auf verschiedenen Frequenzen gesendet, übermittelt und letztendlich empfangen werden. Die mindestens einmalig vorgenommene Übermittlung des mindestens eine Datums unter dem Frequenzversatz erfolgt üblicherweise zeitversetzt, bspw. nach der Übermittlung über die Nominalfrequenz. Falls das mindestens eine Datum mehrmals unter mindestens einem Frequenzversatz oder mehrere Frequenzversätze erfolgt, werden derartige Übermittlungen typischerweise zeitversetzt und nacheinander durchgeführt.Thus, the at least one datum can be transmitted redundantly on different frequencies, transmitted and finally received. The transmission of the at least one datum under the frequency offset carried out at least once is usually carried out with a time delay, for example after the transmission via the nominal frequency. If the at least one date occurs several times under at least one frequency offset or multiple frequency offsets, such transmissions are typically time-delayed and performed one at a time.

In Ausgestaltung wird das mindestens eine Datum zunächst unter einem ersten Frequenzversatz zu der Nominalfrequenz und anschließend unter einem zweiten Frequenzversatz zu der Nominalfrequenz gesendet. Dabei können der erste und der zweite Frequenzversatz diesselben Beträge jedoch unterschiedliche Vorzeichen aufweisen. Dies kann bedeuten, dass das mindestens eine Datum zunächst unter einem Frequenzversatz von x Hertz oberhalb der Nominalfrequenz und danach unter einem Frequenzversatz von Hertz unterhalb der Nominalfrequenz gesendet wird.In an embodiment, the at least one datum is first sent to the nominal frequency at a first frequency offset and then at a second frequency offset to the nominal frequency. However, the first and the second frequency offset can have the same amounts but different signs. This may mean that the at least one datum is first transmitted at a frequency offset of x Hertz above the nominal frequency and thereafter at a frequency offset of Hertz below the nominal frequency.

Mit der Erfindung kann somit eine Zuverlässigkeit von Anordnungen bzw. Systemen zur Übermittlung von Daten, die mindestens einen Sender und mindestens einen Empfänger aufweisen, erhöht werden. Eine mögliche Anwendung der Erfindung ist im Bereich sog. Social Alarm Funksysteme, d. h. sog. Hausnotrufanlagen, möglich.With the invention, a reliability of arrangements or systems for transmitting data which have at least one transmitter and at least one receiver can thus be increased. One possible application of the invention is in the area of so-called social alarm radio systems, i. H. so-called house emergency call systems, possible.

Die Erhöhung der Zuverlässigkeit der Anordnung bzw. des Systems wird u. a. dadurch erreicht, dass der Sender das mindestens eine Datum, das ggf. als Datenprotokoll bereitgestellt wird, nicht nur einmal auf seiner Nominalfrequenz, d. h. der üblich eingestellten Frequenz, sondern anschließend noch mindestens einmal unter einem geringen Frequenzversatz zu der Nominalfrequenz nach Minus und anschließend nach Plus innerhalb eines Kanals des Senders. So ist es möglich, dass das mindestens eine Datum und somit das Datenprotokoll zunächst auf der Nominalfrequenz übermittelt wird. Dann wird das mindestens eine Datum unter Bereitstellung des geringen minimalen Frequenzversatzes auf einer Frequenz, die der Nominalfrequenz abzüglich des Frequenzversatzes entspricht, übermittelt. Anschließend wird das Datum zur Bereitstellung des positiven Frequenzversatzes auf einer Frequenz, die der Nominalfrequenz zuzüglich des Frequenzversatzes entspricht, übermittelt. Hierbei kann vorgesehen sein, dass die beiden Frequenzversätze identisch groß sind. In der Regel befindet sich jeweils ein Frequenzversatz innerhalb eines Frequenzintervalls eines Kanals des Senders.The increase in the reliability of the arrangement or the system is u. a. achieved in that the transmitter, the at least one date, which may be provided as a data protocol, not only once at its nominal frequency, d. H. the frequency usually set, but then at least once at a low frequency offset to the nominal frequency to minus and then to plus within a channel of the transmitter. So it is possible that the at least one date and thus the data protocol is first transmitted on the nominal frequency. Then, the at least one datum is transmitted to provide the low minimum frequency offset at a frequency corresponding to the nominal frequency minus the frequency offset. Subsequently, the date for providing the positive frequency offset is transmitted at a frequency corresponding to the nominal frequency plus the frequency offset. It can be provided that the two frequency offsets are identical. As a rule, there is a frequency offset within a frequency interval of a channel of the transmitter.

In einer Variante wird das mindestens eine Datum für jede Frequenz, auf der das mindestens eine Datum gesendet wird, mit derselben Datenkennung ausgestattet. Alternativ hierzu kann das mindestens eine Datum für jede Frequenz, auf der das mindestens eine Datum gesendet wird, mit einer eigenen Datenkennung ausgestattet werden. Somit weist das Datum in diesem Fall, für jede der redundanten Übermittlungen für jede Frequenz eine andere Datenkennung auf.In one variant, the at least one datum for each frequency on which the at least one datum is transmitted is provided with the same datum identifier. Alternatively, the at least one date for each frequency on which the at least one date is sent, be equipped with its own data identifier. Thus, the date in this case has a different data tag for each of the redundant transmissions for each frequency.

Im Rahmen der Übermittlung wird das mindestens eine Datum von einem Empfänger empfangen, wobei von dem Empfänger ein Hinweis, in der Regel eine Warn- bzw. Wartungsmeldung generiert und somit erzeugt wird, falls der Empfänger das mindestens eine Datum nicht auf der Nominalfrequenz des Senders empfängt. Weiterhin kann eine Empfangsfrequenz des Empfängers unter Berücksichtigung eines Frequenzversatzes auf eine von der Nominalfrequenz abweichende Frequenz nachgestellt werden, falls der Empfänger das mindestens eine Datum nicht auf der Nominalfrequenz des Senders empfängt. Somit ist ein sog. frequenzabhängiges Nachstimmen des Empfängers möglich.As part of the transmission, the at least one datum is received by a receiver, wherein the receiver generates an indication, as a rule a warning or maintenance message, and thus generates it, if the receiver does not receive the at least one datum at the nominal frequency of the transmitter , Furthermore, a receiving frequency of the receiver, taking into account a frequency offset to be adjusted to a different frequency from the nominal frequency, if the receiver does not receive the at least one date on the nominal frequency of the transmitter. Thus, a so-called. Frequency-dependent retuning of the receiver is possible.

Das mindestens eine Datum kann ein Datenprotokoll umfassen und demnach auch als ein Datenprotokoll ausgebildet sein.The at least one datum may comprise a data protocol and therefore also be designed as a data protocol.

Die Erfindung betrifft außerdem eine Anordnung zur Übermittlung von mindestens einem Datum, die als Komponente einen Sender mit einer Nominalfrequenz zum Senden von Daten aufweist, wobei dieser Sender dazu ausgebildet ist, das mindestens eine Datum zunächst auf der Nominalfrequenz und anschließend mindestens einmal unter einem ersten Frequenzversatz zu der Nominalfrequenz zu senden.The invention also relates to an arrangement for transmitting at least one datum having as component a transmitter with a nominal frequency for transmitting data, this transmitter being designed to transmit the at least one datum first at the nominal frequency and then at least once below a first frequency offset to send to the nominal frequency.

Die Anordnung kann mindestens einen Empfänger aufweisen und als eine Haus-Notrufanlage ausgebildet sein.The arrangement may have at least one receiver and be designed as a home emergency call system.

Die beschriebene Anordnung ist dazu ausgebildet, sämtliche Schritte des vorgestellten Verfahrens durchzuführen. Dabei können einzelne Schritte dieses Verfahrens auch von einzelnen Komponenten, typischerweise dem Sender und/oder dem Empfänger, der Anordnung durchgeführt werden. Weiterhin können Funktionen der Anordnung oder Funktionen von einzelnen Komponenten der Anordnung als Schritte des Verfahrens umgesetzt werden.The arrangement described is designed to carry out all the steps of the presented method. In this case, individual steps of this method can also be carried out by individual components, typically the transmitter and / or the receiver, the arrangement. Furthermore, functions of the arrangement or functions of individual components of the arrangement can be implemented as steps of the method.

Die Erfindung betrifft weiterhin ein Computerprogramm mit Programmcodemitteln, um alle Schritte eines beschriebenen Verfahrens durchzuführen, wenn das Computerprogramm auf einem Computer oder einer entsprechenden Recheneinheit, insbesondere in einer erfindungsgemäßen Anordnung, ausgeführt wird.The invention further relates to a computer program with program code means in order to perform all the steps of a described method when the computer program is executed on a computer or a corresponding arithmetic unit, in particular in an arrangement according to the invention.

Das erfindungsgemäße Computerprogrammprodukt mit Programmcodemitteln, die auf einem computerlesbaren Datenträger gespeichert sind, ist zum Durchführen aller Schritte eines beschriebenen Verfahrens ausgebildet, wenn das Computerprogramm auf einem Computer oder einer entsprechenden Recheneinheit, insbesondere in einer erfindungsgemäßen Anordnung, ausgeführt wird.The computer program product according to the invention with program code means which are stored on a computer-readable data carrier is designed to carry out all the steps of a described method when the computer program is executed on a computer or a corresponding arithmetic unit, in particular in an arrangement according to the invention.

Die vorliegende Erfindung ist weiterhin für sog. Schmalband-Multikanalfunksignalsender und/oder -Empfänger geeignet. Für derartige Sender bzw. Empfänger und somit Funkanordnungen bzw. -Systeme, die auch für sog. Hausnotrufanlagen verwendet werden können, gilt nach derzeitiger Lage die Europäische Norm EN 300 220, so dass für diese Funkanordnungen bestimmte Eigenschaften einzuhalten sind. Eine Einhaltung dieser Eigenschaften ist typischerweise unter Bereitstellung von sog. Nachbarkanalselektion durch eine vergleichsweise kleine Empfangsbreite zu realisieren. Falls bspw. eine Übertragung im 869 Megahertzbereich vorgesehen ist, ist als übliches Raster für einen Kanal eine Frequenz von 25 kHz, was einer Empfangsbandbreite von ca. 11 kHz in der Praxis entspricht, vorgesehen.The present invention is further suitable for so-called narrow band multi-channel radio signal transmitters and / or receivers. For such transmitter or receiver and thus radio devices or systems that are also used for so-called. Home alarm systems According to the current situation, the European standard EN 300 220 applies, so that certain characteristics must be observed for these radio arrangements. Compliance with these properties is typically achieved by providing so-called adjacent channel selection by means of a comparatively small reception width. If, for example, a transmission in the 869 megahertz range is provided, the usual pitch for a channel is a frequency of 25 kHz, which corresponds to a reception bandwidth of about 11 kHz in practice.

Demnach ist die Empfangsbandbreite kleiner als das Kanalraster, da an den Bandgrenzen bereits eine Selektion in einer Größenordnung von ca. 70 dB gefordert ist. Eine derartige Auswahl bzw. Selektion wird in der Regel in einer sog. Zwischenfrequenz erzeugt, kann jedoch auch über zwei Zwischenfrequenzen mit einem Überlagerungsempfänger, der auch als Doppelsuper bezeichnet wird, erreicht werden. Hierbei kann eine erste Zwischenfrequenz 10,7 Megahertz und eine zweite Zwischenfrequenz 450 kHz betragen. Eine beschriebene Zwischenfrequenz kann durch Mischung einer Empfangsfrequenz mit einer Oszillatorfrequenz (LO, local oszillator) entstehen. Da die Zwischenfrequenz typischerweise gegenüber der Empfangsfrequenz sehr klein ist, liegt die Oszillatorfrequenz nahe der Empfangsfrequenz, also sehr hoch, bspw. in einem Frequenzbereich von 850 Megahertz.Accordingly, the reception bandwidth is smaller than the channel spacing, as already at the band limits a selection in the order of about 70 dB is required. Such a selection or selection is usually generated in a so-called. Intermediate frequency, but can also be achieved via two intermediate frequencies with a heterodyne receiver, which is also referred to as a double super. Here, a first intermediate frequency 10.7 megahertz and a second intermediate frequency 450 kHz. An intermediate frequency described can arise by mixing a receiving frequency with an oscillator frequency (LO, local oscillator). Since the intermediate frequency is typically very small compared to the reception frequency, the oscillator frequency is close to the reception frequency, ie very high, for example in a frequency range of 850 megahertz.

Falls in Ausgestaltung die Empfangsfrequenz bspw. 869,2125 Megahertz beträgt und die erste Zwischenfrequenz 10,7 Megahertz beträt, ergibt sich, dass die Oszillatorfrequenz 858,5125 Megahertz beträgt. Demnach ergibt sich die Oszillatorfrequenz als Summe der Empfangsfrequenz sowie der ersten Zwischenfrequenz. Um eine hinreichende Stabilität zu erreichen, so dass der Empfang gewährleistet ist, ist vorgesehen, dass die Frequenz innerhalb der Empfangsbreite abzüglich eines Frequenzhubs des zu empfangenden Senders eingestelt ist und/oder bleibt.If the reception frequency is, for example, 869.2125 megahertz in an embodiment and the first intermediate frequency is 10.7 megahertz, it follows that the oscillator frequency is 858.5125 megahertz. Accordingly, the oscillator frequency is the sum of the reception frequency and the first intermediate frequency. In order to achieve a sufficient stability, so that the reception is ensured, it is provided that the frequency is set within the reception width minus a frequency deviation of the transmitter to be received and / or remains.

Falls bspw. eine Empfangsbandbreite eine Frequenz von 11 kHz umfasst und ein Frequenzhub üblicherweise einen Wert von +/- 3 kHz umfasst, ergibt sich aus der Empfangsbandbreite abzüglich eines Betrags des Frequenzhubs hier ein Wert für die Oszillatorfrequenz von 8 kHz was übertragen einem Frequenzversatz der Oszillatorfrequenz von +/- 4 kHz entspricht. Diese Oszillatorfrequenz von +/- 4 kHz entspricht bei einer Empfangsfrequenz von 869 Megahertz einer Abweichung von 4,6 ppm (parts per million). Eine derartige Abweichung teilen sich üblicherweise der Sender und der Empfänger, was bedeutet, dass üblicherweise 50% der Abweichung vom Sender verursacht und ca. 50% durch den Empfänger aufgrund einer Abweichung der empfangbare Frequenz verursacht wird. Unter der Annahme, dass eine Abweichung des Senders nur +/- 0,6 ppm beträgt, verbleiben für den Empfänger +/- 4 ppm d. h. +/- 3,5 kHz für eine maximal zulässige Abweichung einschließlich eines Temperaturdrifts, einer Quarzalterung, einer Abgleichtoleranz usw.If, for example, a reception bandwidth has a frequency of 11 kHz and a frequency deviation usually has a value of +/- 3 kHz, the reception bandwidth minus an amount of the frequency deviation results in a value for the oscillator frequency of 8 kHz which transmits a frequency offset of the oscillator frequency of +/- 4 kHz. This oscillator frequency of +/- 4 kHz corresponds to a deviation of 4.6 ppm (parts per million) at a reception frequency of 869 megahertz. Such a deviation is usually shared between the transmitter and the receiver, which means that usually 50% of the deviation is caused by the transmitter and about 50% by the receiver due to a Deviation of the receivable frequency is caused. Assuming that the deviation of the transmitter is only +/- 0.6 ppm, the receiver will remain +/- 4 ppm ie +/- 3.5 kHz for a maximum allowable deviation including a temperature drift, a quartz aging, a match tolerance etc.

Im Rahmen der vorliegenden Erfindung können die einschlägigen Normen bzgl. einer zulässigen Frequenzabgleichung und eines sog. duty cycles, d. h. einer Dauer einer Aussendung, berücksichtigt werden.In the context of the present invention, the relevant standards with respect to a permissible frequency adjustment and a so-called duty cycles, d. H. duration of a broadcast.

In einer Ausgestaltung kann vorgesehen sein, dass ein Frequenzversatz bspw. 2 kHz beträgt. Außerdem kann vorgesehen sein, dass der Empfänger auf eine Soll-Frequenz, d. h. die Nominalfrequenz des Senders, eingestellt ist. Somit empfängt der Empfänger zunächst das zuerst gesendete mindestens eine Datum bzw. Datenprotokoll. Falls ein Empfangsbereich des Empfängers jedoch um 2 kHz zu einer tieferen Frequenz gedriftet sein sollte, kann dies bedeuten, dass der Empfänger ggf. das zuerst auf der Nominalfrequenz von dem Sender gesendete mindestens eine Datum nicht aber mindestens eines der nachfolgenden unter dem Frequenzversatz gesendeten eine Datum empfangen kann. Eine Ist-Frequenz, unter der das mindestens eine Datum tatsächlich gesendet wird, kann von der Soll-Frequenz und somit von der Nominalfrequenz abweichen.In one embodiment, it can be provided that a frequency offset is, for example, 2 kHz. In addition, it can be provided that the receiver to a desired frequency, d. H. the nominal frequency of the transmitter is set. Thus, the receiver first receives the at least one date or data protocol sent first. However, if a receive range of the receiver were to be drifted 2 kHz to a lower frequency, this may mean that the receiver may miss the at least one datum sent first at the nominal frequency from the transmitter, but not at least one of the subsequent ones sent below the frequency offset can receive. An actual frequency under which the at least one datum is actually transmitted may deviate from the nominal frequency and thus from the nominal frequency.

Falls in Ausgestaltung der Erfindung vorgesehen sein sollte, dass der Sender das mindestens eine Datum zuerst auf seiner Nominalfrequenz und dann zunächst unter einem negativen Frequenzversatz relativ zu der Nominalfrequenz und danach unter einem positiven Frequenzversatz relativ zu der Nominalfrequenz versendet, kann der Empfangsbereich des Empfängers dieses mindestens eine Datum bspw. auch dann empfangen, falls der Empfänger zu einer um 3 kHz zu hohen Frequenz gedriftet sein sollte. Dabei empfängt der Empfänger zwar das mindestens eine zuerst auf der Nominalfrequenz gesendete Datum sowie das mindestens eine unter dem negativen Frequenzversatz gesendete Datum nicht, allerdings ist es dem Empfänger möglich, das mindestens eine dritte unter positiven Frequenzversatz gesendete Signal zu empfangen.If, in an embodiment of the invention, it should be provided that the transmitter sends the at least one datum first at its nominal frequency and then at a negative frequency offset relative to the nominal frequency and then at a positive frequency offset relative to the nominal frequency, the receiver's receiving range can transmit this at least receive a date, for example, even if the receiver should be drifted to a frequency that is too high by 3 kHz. Although the receiver does not receive the at least one datum transmitted first at the nominal frequency and the at least one datum transmitted under the negative frequency offset, it is possible for the receiver to receive the at least one third signal transmitted under positive frequency offset.

Im Rahmen der Erfindung bietet sich als eine weitere Option an, falls das mindestens eine unter unterschiedlichen Frequenzen ausgesendete Datum dreimal bspw. als Datenprotokoll gesendet wird, dass das mindestens eine Datum bzw. eine Datenprotokoll mit unterschiedlichen Datenkennungen oder Nummern auszustatten. Somit ist es dem Empfänger möglich, aufgrund unterschiedlicher Ausbildungen des mindestens ein Datums bzw. eines Datenprotokolls zu unterscheiden, welches mindestens ein Datum der Empfänger empfangen hat. Bei Nichtempfang des mindestens einen Datums auf einer bestimmten Frequenz, typischerweise der Nominalfrequenz des Senders, kann der Empfänger als Hinweis eine Warn- bzw. Wartungsmeldung bereitstellen.Within the scope of the invention, another option is provided if the at least one datum transmitted at different frequencies is sent three times as a data protocol, for example will equip that at least one date or a data log with different data identifiers or numbers. Thus, it is possible for the receiver to differentiate due to different configurations of at least one date or a data protocol, which has received at least one date of the receiver. Failure to receive the at least one date on a particular frequency, typically the sender's nominal frequency, may provide the receiver with a warning or maintenance message as an indication.

Eine Anordnung, die als drahtlose Hausnotrufanlage bzw. ein sog. Social Alarm Sender ausgebildet sein kann, weist im Rahmen der Erfindung einen Sender auf, der nach Aussendung des mindestens einen Datums auf seiner Nominalfrequenz eine weitere Aussendung bzw. Sendung des mindestens einem Datums mit einem leichten Frequenzversatz zu tieferen Frequenzen innerhalb des üblicherweise gleichen Kanals durchführt. Nach Aussendung des mindestens ein Datums auf der Nominalfrequenz kann der Sender alternativ oder ergänzend eine weitere Sendung bzw. Aussendung mit einem leichten Frequenzversatz hin zu höheren Frequenzen innerhalb des üblicherweise gleichen Kanals durchführen. Somit erfolgt eine mindestens einmal redundante Sendung des mindestens eines Signals auf mindestens zwei unterschiedlichen jedoch nah beieinander liegenden Frequenzen, dass diese beiden Frequenzen nahe beieinander liegen, kann dadurch erreicht werden, dass sie innerhalb des gleichen Kanals liegen. Üblicherweise wird das mindestens eine Datum und somit das Datenprotokoll dreimal d. h. auf der Nominalfrequenz sowie unter einem leichten Frequenzversatz zu einer tieferen und einer höheren Frequenz innerhalb des gleichen Kanal übermittelt.An arrangement which can be configured as a wireless home emergency call system or a so-called social alarm transmitter has, in the context of the invention, a transmitter which, after the at least one datum has been transmitted at its nominal frequency, transmits or transmits the at least one datum again slight frequency offset to lower frequencies within the usually same channel. After the at least one date has been transmitted at the nominal frequency, the transmitter can alternatively or additionally carry out another transmission or transmission with a slight frequency offset towards higher frequencies within the usually same channel. Thus, an at least one redundant transmission of the at least one signal on at least two different but closely spaced frequencies that these two frequencies are close to each other, can be achieved that they are within the same channel. Usually, the at least one date and thus the data protocol three times d. H. transmitted at the nominal frequency and with a slight frequency offset to a lower and a higher frequency within the same channel.

Je nach Ausgestaltung kann das mindestens eine Datum, das auf den unterschiedlichen Frequenzen mehrfach gesendet wird, identisch ausgebildet sein oder sich bzgl. einer Datenkennung bei einer jeweiligen frequenzabhängigen Sendung unterscheiden. Falls der Empfänger bspw. für den Fall, dass das mindestens eine Datum frequenzabhängig unterschiedlich ausgebildet ist, nicht sämtliche Daten bzw. Datenprotokolle empfangen kann, kann dieses im Empfänger erfassten Summe registriert werden, so dass der Empfänger auf Grundlage die Warn- bzw. Wartungsmeldung generiert. Weiterhin ist für den Fall, dass der Empfänger das mindestens eine Datum nicht auf allen Frequenzen sondern nur auf einer Frequenz empfängt, ein statisches Nachstimmen eines Empfangsbereichs des Empfängers hin zu jener Frequenz, auf der das mindestens eine Datum empfangen wurde, möglich.Depending on the configuration, the at least one datum, which is transmitted several times on the different frequencies, may be of identical design or differ with respect to a data identifier in the case of a respective frequency-dependent transmission. If the receiver, for example, in the event that the at least one date is formed differently depending on frequency, can not receive all data or data logs, this recorded in the receiver sum can be registered, so that the receiver generates based on the warning or maintenance message , Furthermore, if the receiver does not receive the at least one datum on all frequencies but only on one frequency, a static re-tuning of a receiving range of the receiver towards that frequency at which the at least one datum was received is possible.

Die vorliegende Erfindung kann auch bereits bei bestehenden Anordnungen, die mindestens einen Sender und mindestens einen Empfänger aufweisen ohne Hardwareänderungen eingesetzt werden. Es ist lediglich erforderlich, Software des mindestens einen Senders und/oder Empfängers anzupassen. Ein bereits bestehender Sender mit veränderter Software ist üblicherweise auch zu bereits vorhandenen Anordnung bzw. Systemen kompatibel. Somit ist es möglich, dass auch ältere, bereits vorhandene Anordnungen der Erfindung, die u. a. die redundante Übertragung von mindestens einem Datum umfasst, so profitieren und somit zuverlässiger zu werden.The present invention can also already be used in existing arrangements having at least one transmitter and at least one receiver without hardware changes. It is only necessary to adapt software of the at least one transmitter and / or receiver. An existing transmitter with modified software is usually also compatible with existing arrangements or systems. Thus, it is possible that even older, already existing arrangements of the invention, the u. a. the redundant transmission of at least one date, so benefit and thus become more reliable.

Ausführungsform der ErfindungEmbodiment of the invention

Die Erfindung ist anhand einer Ausführungsform in den Zeichnungen schematisch dargestellt und wird im folgenden unter Bezugnahme auf die Zeichnungen ausführlich beschrieben.The invention is schematically illustrated by means of an embodiment in the drawings and will be described in detail below with reference to the drawings.

Die Figuren werden zusammenhängend und übergreifend beschrieben, gleiche Bezugszeichen bezeichnen gleiche Komponenten.The figures are described in a coherent and comprehensive manner, like reference numerals designate like components.

Figur 1 zeigt in schematischer Darstellung eine Ausführungsform einer erfindungsgemäßen Anordnung 2, die einen Sender 4 mit einem als Antenne ausgebildeten Sendemodul 6 und einen Empfänger 8 mit einem als Antenne ausgebildeten Sendemodul 10 aufweist. FIG. 1 shows a schematic representation of an embodiment of an inventive arrangement 2, which has a transmitter 4 with a transmitter module 6 designed as an antenna and a receiver 8 with a transmitter module 10 designed as an antenna.

Zum Übertragen von Informationen zwischen dem Sender 4 und dem Empfänger 8 ist bei einer drahtlosen Übermittlung vorgesehen, dass die Informationen über elektromagnetische Wellen auf einer Nominalfrequenz 14 (Figur 2) von dem Sender 4 gesendet und von dem Empfänger 8, dessen Empfangsbereich auf diese Nominalfrequenz 14 eingestellt ist, empfangen werden.For transmitting information between the transmitter 4 and the receiver 8, in the case of a wireless transmission it is provided that the information about electromagnetic waves is transmitted at a nominal frequency 14 (FIG. FIG. 2 ) are transmitted from the transmitter 4 and received by the receiver 8 whose reception range is set to this nominal frequency 14.

Bei einer Ausführungsform der Erfindung ist jedoch vorgesehen, dass eine redundante Übermittlung des mindestens einem Datums von dem Sender 4 zu dem Empfänger 8 ausgeführt wird. Details zu dieser Ausgestaltung des erfindungsgemäßen Verfahrens gehen aus dem Diagramm aus Figur 2 hervor.In one embodiment of the invention, however, it is provided that a redundant transmission of the at least one datum from the transmitter 4 to the receiver 8 is carried out. Details of this embodiment of the method according to the invention are based on the diagram FIG. 2 out.

In dem Diagramm aus Figur 2 sind entlang einer vertikal orientierten Achse 16 über einer horizontal orientierten Achse 18 für die Zeit Frequenzen aufgetragen, mit denen der Sender 4 das mindestens eine Datum sendet.In the diagram FIG. 2 are plotted along a vertically oriented axis 16 over a horizontally oriented axis 18 for the time frequencies at which the transmitter 4 transmits the at least one date.

Im Rahmen dieser Ausführungsform des Verfahrens wird das mindestens eine Datum in einem Zeitintervall bis zu einem ersten Zeitpunkt 20 auf der Nominalfrequenz 14 des Senders 4 gesendet. Während eines zweiten Zeitintervalls zwischen dem ersten Zeitpunkt 20 und einem zweiten Zeitpunkt 22 wird das mindestens eine Datum unter einem negativen Frequenzversatz 24 gesendet, das bedeutet, dass das mindestens eine Datum auf einer erniedrigten Frequenz 26, die der Nominalfrequenz 14 abzüglich des Frequenzversatzes 24 entspricht, gesendet wird. Während eines dritten Zeitintervalls wird das mindestens eine Datum zwischen dem zweiten Zeitpunkt 22 und einem dritten Zeitpunkt 28 unter einem erhöhten Frequenzversatz 24 gesendet. Dies bedeutet, dass das mindestens eine Datum nun auf einer erhöhten Frequenz 30, die einer Summe der Nominalfrequenz 14 und dem Frequenzversatz 24 entspricht, gesendet wird.In the context of this embodiment of the method, the at least one datum is transmitted in a time interval up to a first time 20 at the nominal frequency 14 of the transmitter 4. During a second time interval between the first time 20 and a second time 22, the at least one datum is transmitted at a negative frequency offset 24, which means that the at least one datum is at a lowered frequency 26 corresponding to the nominal frequency 14 minus the frequency offset 24, is sent. During a third time interval, the at least one datum is transmitted between the second time 22 and a third time 28 at an increased frequency offset 24. This means that the at least one datum is now transmitted on an increased frequency 30, which corresponds to a sum of the nominal frequency 14 and the frequency offset 24.

Somit ist in vorliegender Ausführungsform des Verfahrens vorgesehen, dass das mindestens eine Datum dreimal nacheinander und somit redundant gesendet wird. Ein Wert des Frequenzversatzes 24 befindet sich innerhalb eines Kanals des Senders 4, so dass die erniedrigte Frequenz 26 sowie die erhöhte Frequenz 30, auf denen das mindestens eine Datum zusätzlich gesendet wird, nur um einen geringen Bruchteil von wenigen Promille von der Nominalfrequenz 14 des Senders 4 abweichen.Thus, in the present embodiment of the method is provided that the at least one date is sent three times in succession and thus redundant. A value of the frequency offset 24 is located within a channel of the transmitter 4, so that the lowered frequency 26 and the increased frequency 30 on which the at least one additional date is transmitted, only to deviate a small fraction of a few per thousand from the nominal frequency 14 of the transmitter 4.

Eine derartige redundante Übertragung des mindestens einem Datums bietet sich bspw. dann an, wenn eine von dem Empfänger 8 empfangbare Frequenz von der Nominalfrequenz 14 abweichen sollte. Die Erfindung ist jedoch auch dann einsetzbar, falls eine Frequenz, mit der der Sender 4 das mindestens eine Datum aussendet, von der Nominalfrequenz 14 abweichen sollte. Bei Vorliegen derartiger Abweichungen ist aufgrund der redundanten Übermittlung des mindestens einen Datums die Möglichkeit gegeben, dass der Empfänger 8 das mindestens eine Datum zumindest einmal empfangen kann.Such a redundant transmission of the at least one date is, for example, then available if a frequency which can be received by the receiver 8 should deviate from the nominal frequency 14. However, the invention can also be used if a frequency with which the transmitter 4 transmits the at least one datum should deviate from the nominal frequency 14. In the presence of such deviations, due to the redundant transmission of the at least one datum, there is the possibility that the receiver 8 can receive the at least one datum at least once.

Bei dem Verfahren zur Übermittlung von mindestens einem Datum wird das mindestens eine Datum zunächst auf der mindestens einen Nominalfrequenz 14 des Senders 4 und anschließend bzw. nachfolgend mindestens einmal unter dem ersten Frequenzversatz zu der Nominalfrequenz 14 des Senders 4 gesendet. Demnach wird das mindestens eine Datum zeitlich mehrmals nacheinander d. h. zeitversetzt gesendet, wobei das mindestens eine Datum zuerst auf der Nominalfrequenz 14 des Senders 4, danach unter dem ersten Frequenzversatz danach unter dem zweiten Frequenzversatz gesendet wird. Es ist jedoch auch möglich, dass sich die vorgesehenen redundanten Übermittlungen und somit Sendungen des mindestens einem Datums zumindest teilweise zeitlich überschneiden, so dass das mindestens eine Datum zumindest teilweise gleichzeitig auf unterschiedlichen Frequenzen gesendet wird.In the method for transmitting at least one datum, the at least one datum is first transmitted on the at least one nominal frequency 14 of the transmitter 4 and subsequently or subsequently at least once below the first frequency offset to the nominal frequency 14 of the transmitter 4. Accordingly, the at least one date in time several times successively d. H. time-shifted, the at least one datum being transmitted first at the nominal frequency 14 of the transmitter 4, then at the first frequency offset thereafter below the second frequency offset. However, it is also possible for the intended redundant transmissions and thus transmissions of the at least one datum to overlap at least partially in time, so that the at least one datum is transmitted at least partially simultaneously on different frequencies.
