Description

Die Erfindung betrifft eine autonome Funkuhr gemäß dem Oberbegriff des Anspruches 1.The invention relates to an autonomous radio clock according to the preamble of claim 1.

Eine derartige Funkuhr, die sich auf dem Markt sehr rasch durchgesetzt hat, ist Gegenstand der DE-U 8 712 803 = EP-B 0 308 880 (nicht vorveröffentlicht) und näher beschrieben in der Goldschmiede-Zeitung Heft 1/1988 Seite 148 ff., W. Ganter "Junghans-Funkuhr RC 2". Diese Funkuhr schaltet ihren Empfänger periodisch, zu vorgegebenen Zeitpunkten vorübergehend ein, um die momentane Zeitanzeige erforderlichenfalls aufgrund aktuell über Funk empfangener und decodierter Zeittelegramme zu korrigieren. Außerdem erfolgt die Empfänger-Einschaltung beim Einlegen einer Batterie bzw. im Betrieb bei Betätigung einer Reset-Senderruftaste, durch die zugleich die momentane Zeitanzeige in eine Referenzstellung (dort 00:00:00-Uhr) gefahren und ein System-Reset des Prozessors ausgelöst wird, in dem die Zeittelegramm-Decodierung und die Umsetzung der Zeitinformation in die Ansteuerung der Zeitanzeige erfolgt. Sobald der Funkempfang eine gültige Zeitinformation erbringt, wird der Empfänger wieder abgeschaltet und die Zeitanzeige im Eilgang in die entsprechende, dertatsächlichen Momentanzeit entsprechende Stellung gebracht. Falls die Zeitanzeige mit optoelektronischen Mitteln arbeitet. erfolgt die elektrische Ansteuerung der entsprechenden optischen Segmente oder Sektoren praktisch verzugsfrei. Wenn für den Übergang aus der Referenzstellung in die Anzeigestellung für die tatsächliche, aktuelle Zeit jedoch mechanische Teile (etwa das Räderwerksgetriebe für Zeiger oder der Antriebsmechanismus für Ziffer-Fallklappen) bewegt werden müssen, dann wird dafür eine endliche Zeitspanne benötigt, die aber bei einer Nachführ-Steuerung automatisch berücksichtigt wird, so daß auch in diesem Falle schließlich die Zeitanzeigemittel die tatsächliche, korrekte Zeit anzeigen.Such a radio clock, which is on the market has prevailed very quickly, is the subject of DE-U 8 712 803 = EP-B 0 308 880 (not previously published) and described in more detail in the Goldschmiede newspaper issue 1/1988 page 148 ff., W. Ganter "Junghans radio clock RC 2". This radio clock switches its receiver periodically, to predetermined ones Times temporarily to the current Time display if necessary based on current Time telegrams received and decoded by radio to correct. The receiver is also switched on when inserting a battery or in operation when a reset transmitter call button is pressed, through which at the same time the momentary Time display in a reference position (there 00:00:00) driven and a system reset of the processor is triggered in which the time telegram decoding and the implementation of the time information in the The time display is activated. Once the Radio reception provides valid time information, the receiver is switched off again and the time display in rapid to the corresponding, the actual one Appropriate position at the moment. If the time display with optoelectronic Means works. the electrical control takes place the corresponding optical segments or sectors practically free of distortion. If for the transition from the reference position to the display position for however, the actual current time is mechanical Parts (such as the gear train for pointers or the drive mechanism for digit drop flaps) moves must then become a finite one Time required, but with a tracking control is automatically taken into account so that in this case too, finally the time display means display the actual correct time.

Als störend könnte eine solche den Prozessor-Reset beim Einschalten des Empfängers hervorrufende Bedienungstaste jedoch empfunden werden, wenn sie ungewollt betätigt wird und dadurch der aktuelle Registerinhalt im Prozessor gelöscht wird. Dann vergeht eine gewisse Zeitspanne, bis genügend Zeittelegramme für deren Untersuchung auf Plausibilität empfangen und decodiert werden konnten, um danach den Registerinhalt und daraus die Zeitanzeige wieder auf die korrekte momentane Zeit zu richten. Das ist besonders dann mißlich, wenn man sich mit seiner Funkuhr am Rande oder außerhalb des Empfangsbereiches des Zeitsenders befindet, so daß nicht ohne weiteres und vielleicht erst in einigen Stunden (bzw. in der bevorstehenden Nacht) wieder ungestörter Empfang von Zeittelegrammen möglich ist, bis dahin also keine Zeitanzeige erfolgt. So kann bei einer Ausgestaltung der Funkuhr als Armbanduhr aufgrund der Tragegegebenheiten eine unwillkürliche, also ungewollte Betätigung der Reset-Taste auftreten. Wenn die Funkuhr als Weckeruhr, also mit Auslösung einer Alarmgabe zu einem vorgebbaren Zeitpunkt ausgestaltet ist, dann kann es geschehen, daß jemand irrtümlich die Prozessor-Resettaste betätigt, obgleich er über einen anderen Schalter ein Alarmton-Wiederholprogramm initiieren wollte. Der Alarm wird jedoch abgebrochen und das Wiederholprogramm nicht gestartet, wenn der für dessen Steuerung verantwortliche Prozessor (irrtümlich) mit allen seinen Steuerungsfunktionen zurückgesetzt wurde.Such a disturbance could be the processor reset when the receiver is switched on Control button, however, are felt if it is activated unintentionally and thereby the current one Register content in the processor is deleted. Then a certain amount of time passes until enough Time telegrams for checking them for plausibility could be received and decoded to then the contents of the register and the time display back to the correct current time. This is especially annoying when you are concerned with his radio clock on the edge or outside the reception area of the time transmitter, so that not easily and maybe only in a few hours (or in the upcoming night) again undisturbed Time telegrams can be received until so there is no time display. So with one Design of the radio clock as a wristwatch an involuntary, thus unwanted actuation of the reset button occur. If the radio clock as an alarm clock, so with trigger an alarm at a predeterminable time is designed, then it can happen that someone accidentally presses the processor reset button, although he has an alarm tone repeat program through another switch wanted to initiate. The alarm however, is canceled and the repeat program not started if the for its control responsible processor (mistakenly) with all its control functions have been reset.

In Erkenntnis dieser Gegebenheiten liegt der Erfindung die Aufgabe zugrunde, bei einer Funkuhr gattungsgemäßer Art einerseits die bewährte einfache Art der Empfänger-Einschaltung (ohne beispielsweise einen Batteriewechsel vornehmen zu müssen) beizubehalten und andererseits doch aus einer unwillkürlichen Fehlbedienung resultierende Betriebsstörungen zu vermeiden.The invention lies in the knowledge of these facts the task is based on a radio clock of the generic type Kind on the one hand the proven simple Type of receiver activation (without, for example to have to change the battery) and on the other hand from an involuntary Operating errors resulting from incorrect operation to avoid.

Diese Aufgabe ist erfindungsgemäß im wesentlichen dadurch gelöst, daß die gattungsgemäße Funkuhr gemäß dem Kennzeichnungsteil des Anspruches 1 ausgestattet ist.This task is essentially according to the invention solved in that the generic Radio clock according to the characterizing part of the claim 1 is equipped.

Nach dieser Lösung ist ein Schalter vorgesehen. der wie bisher als Senderruftaste bezeichnet werden kann, dessen Betätigung aber keinen Prozessor-Reset sondern nur die - vorübergehende - Einschaltung des Empfängers hervorruft. Es wird die Anzeige wieder in eine definierte Referenzstellung gefahren, um deutlich zu machen, daß eine neue Synchronisation dieser Funkuhr bevorsteht. Sollte der Empfang jedoch nicht zu verwertbaren Zeitinformationen führen, dann wird zur Reduzierung des Leistungsbedarfes der Funkuhr der Empfänger wieder abgeschaltet und die Zeitanzeigeeinrichtung fortan wieder aus dem (zuvor nicht gelöschten und zeithaltend weitergetakteten) Register betrieben. Die irrtümliche oder spielerische Betätigung des Empfänger-Schalters führt also bei schlechten Funkempfangsgegebenheiten nicht zu einem länger dauernden Ausfall der Anzeige der immer noch korrekten Zeit, und auch etwaige eingegebene zeitabhängige Funktionen wie etwa ein Alarmgabeprogramm wurden nicht gelöscht, stehen also weiterhin ohne neue Eingabeerfordernisse zur zeitabhängigen Aktivierung bzw. zum ungestörten Ablauf nach ihrer Aktivierung zur Verfügung. Auch erfolgt weiterhin, gesteuert aus dem nicht gelöschten Zeitregister, die periodische (z.B. stündlich oder tägliche) kurzzeitige Empfänger-Einschaltung, um aufgrund aktuell empfangener Zeittelegramme die tatsächliche Zeitanzeige zu kontrollieren und erforderlichenfalls zu korrigieren.According to this solution, a switch is provided. which are referred to as the transmitter call button as before can, but its operation does not reset the processor but only the - temporary - activation of the recipient. It the display returns to a defined reference position driven to make it clear that a new synchronization of this radio clock is imminent. However, the receipt should not be usable Time information then leads to reduction the power requirement of the radio clock of the receiver switched off again and the time display device henceforth again from the (previously not deleted and timed) register operated. The erroneous or playful operation of the receiver switch leads to poor radio reception conditions not a longer one Failure to display the still correct Time, and also any entered time-dependent Features such as an alarm program have been not deleted, so they are still without new ones Entry requirements for time-dependent activation or the undisturbed process after their activation to disposal. Also continues to be controlled from the undeleted time register, the periodic (e.g. hourly or daily) short-term receiver activation, order based on currently received Time telegrams the actual time display check and correct if necessary.

Trotz der erfindungsgemäß vorgenommenen Trennung einer Einwirkung des Empfänger-Schalters auf den Betrieb des Prozessors (für die Decodierung der empfangenen Zeittelegramme und für die danach anzusteuernden weiteren Funktionen wie Anzeigen und Alarmgabe-Komparatoren) kann es zweckmäßig sein, einen Prozessor-Reset manuell auszulösen. Dafür ist dann zweckmäßigerweise der herkömmliche Reset-Schalter so verdeckt, etwa: versenkt, eingebaut, daß er nicht irrtümlich und ungewollt betätigt werden kann. Für die Betätigung bedarf es dann eines Hilfsmittels, wie etwa einer Bleistiftspitze, um einen Prozesssor-Reset ganz bewußt herbeizuführen, beispielsweise wenn aufgrund einer Reise in den Empfangsbereich eines anderen Senders und einer anderen Zeitzone ein kompletter Neustart der Funkuhr wünschenswert erscheint.Despite those made according to the invention Disconnection of the action of the receiver switch on the operation of the processor (for decoding of the received time telegrams and for those afterwards other functions to be controlled such as displays and alarm comparators) it can be useful be to trigger a processor reset manually. The conventional one is then expedient for this Reset switch so hidden, for example: recessed, installed, that he doesn't accidentally and accidentally operate can be. One is then required for operation Tools, such as a pencil tip, around one To bring about the process sensor reset deliberately, for example, when traveling to the Reception area of another transmitter and one another time zone, a complete restart of the radio clock seems desirable.

Es ist zweckmäßig, dem Benutzer der Funkuhr eine Information darüber zu vermitteln, wie lange die letzte Kontrolle und gegebenenfalls Korrektur der Zeitanzeige aufgrund eines empfangenen Zeittelegrammes schon zurückliegt, mit welchen Unsicherheiten unterdessen also die aktuelle Zeitanzeige behaftet sein kann. Dafür werden zweckmäßigerweise die Zyklen gezählt, in denen die periodische prozessorgesteuerte vorübergehende Wieder-Einschaltung des Empfängers auftrat, ohne zu einer verwertbaren Zeitinformation geführt zu haben. Angezeigt wird das Zählergebnis, also etwa Stunden bei stündlicher Empfängereinschaltung oder Tage bei täglicher Empfängereinschaltung. Diese Anzeige wird auf den Zählanfangswert (Null) zurückgesetzt bzw. ganz gelöscht, wenn eine Zeittelegramm-Decodierung zu verwertbaren Zeitinformationen führt schon die bloße Tatsache, daß eine Anzeige erscheint, macht dann erkennbar, daß außergewöhnlich schlechte Funkempfangsverhältnisse vorliegen, daß nämlich ungeplant lange keine Überprüfung der angezeigten Zeit stattfinden konnte. Wenn und solange der Empfänger eingeschaltet ist - sei es aufgrund der penodischen Steuerung aus dem Prozessor-Zeitregister heraus, sei es aufgrund der Betätigung des Empfänger-Schalters oder des Reset-Schalters - wird diese Tatsache zweckmäßigerweise dem Benutzer dadurch kenntlich gemacht, daß die Anzeige (unabhängig vom momentanen Anzeigeinhalt) ein auffallendes Signal gibt, beispielsweise blinkt. Dadurch erfährt der Benutzer der Funkuhr zugleich eine Bestätigung darüber, daß die manuelle Operation an einem Schalter wie gewünscht zur Empfänger-Einschaltung geführt hat und nun (bei ausreichenden Emfpangsverhältnissen) zur Überprüfung und gegebenfalls Korrektur der Zeitanzeige führen müßte, dann unter gleichzeitiger Rücksetzung eines etwaigen Zähl-Saldos für die Empfangsversuche.It is expedient, the user of the radio clock provide information about how long the final check and, if necessary, correction of the Time display based on a received time telegram with what uncertainties meanwhile the current time display is affected can be. For this, it will be convenient counted the cycles in which the periodic processor controlled temporary reactivation of the recipient occurred without becoming a usable To have time information. This is shown Counting result, i.e. approximately hours at hourly Receiver activation or days with daily receiver activation. This display will change to the start count value Reset (zero) or completely deleted, if a time telegram decoding is usable Time information leads the mere fact that an advertisement appears then makes it recognizable that exceptionally poor radio reception conditions exist that namely unplanned long no check of the displayed time take place could. If and as long as the receiver is switched on is - be it due to the penodic control out of the processor time register, either due to the operation of the receiver switch or the reset switch - this fact This is expediently recognizable to the user made that the display (regardless of the current Display content) gives a striking signal, for example, flashing. This tells the user the radio clock at the same time a confirmation that manual operation on a switch as desired has led to receiver activation and now (with sufficient reception conditions) for Checking and, if necessary, correcting the time display should lead, then with simultaneous resetting a possible count balance for the reception attempts.

Zusätzliche Alternativen und Weiterbildungen sowie weitere Vorteile der Erfindung ergeben sich aus den weiteren Ansprüchen und aus nachstehender Beschreibung eines in der Zeichnung unter Beschränkung auf das wesentliche stark abstrahiert skizzierten bevorzugten Realisierungsbeispiels zur erfindungsgemäßen Lösung. Die einzige Figur der Zeichnung zeigt im einpoligen Blockschaltbild eine autonome Funkuhr mit Senderruftaste, deren Betätigung noch nicht gleich zum Reset des Prozessors für die Gewinnung und Verwaltung zeitabgeleiteter Informationen führt.Additional alternatives and training as well further advantages of the invention result itself from the further claims and from the description below one in the drawing limited to that essential highly abstracted preferred Realization example of the invention Solution. The only figure in the drawing shows the single-pole Block diagram of an autonomous radio clock with Transmitter call button, the actuation of which is not yet the same to reset the processor for extraction and Management of time-derived information leads.

Die skizzierte Funkuhr 11 weist einen an eine Antenne 12 angeschlossenen auf eine Zeitsender-Frequenz abgestimmten oder abstimmbaren Empfänger 13 mit Decodierer 14 für die in der demodulierten Empfangsinformation 15 enthaltene aktuelle Zeitinformation 16 auf. Diese decodierte Zeitinformation 16 wird in ein Register 17 zur Ansteuerung einer Zeitanzeigeeinrichtung 18 übergeben, bei der es sich (wie zeichnerisch angedeutet) um eine Zeigerdarstellung handeln kann, oder aber (in der Zeichnung nicht berücksichtigt) um eine digitale (ziffernmäßige) Darbietung der aktuellen Zeitinformation 16. In beiden Fällen kann die Darbietung über mechanisch bewegte Elemente (Zeiger, Fallklappen) erfolgen, oder aber über entsprechende Segment- oder Sektoransteuerungen von elektrooptischen Displays.The sketched radio clock 11 has an antenna 12 connected to a time transmitter frequency matched or tunable receiver 13 with decoder 14 for those in the demodulated Reception information 15 contains current time information 16 on. This decoded time information 16 is in a register 17 for controlling a time display device 18 passed, which is (as indicated in the drawing) around a pointer representation can act or not (in the drawing a digital (numerical) presentation the current time information 16. In both Cases can be performed via mechanically moving Elements (pointers, trap doors) take place, or else via appropriate segment or sector controls of electro-optical displays.

Es ist ein Reset-Schalter 19 vorgesehen bei dessen manueller Betätigung ein Reset-Signal 20 ausgelöst wird, das über eine bistabile Schaltung 21 die Empfangseinrichtung (also den Empfänger 13 und gegebenenfalls den Decodierer 14) einschaltet, die zur Leistungsersparnis insbesondere bei einer batteriebetriebenen Funkuhr 11 normalerweise abgeschaltet ist. Nach einer vorgegebenen Zeitspanne T - in der Zeichnung repräsentiert durch eine monostabile oder Zeit-Schaltung 22 -, oder aber wenn der Funkempfang eine verwertbare Zeitinformation 16 geliefert hat und deshalb ein Empfangs-Bestätigungssignal 23 erscheint, wird ein Abschaltimpuls 24 erzeugt, der die bistabile Schaltung 21 in den Ausgangszustand zurücksetzt und dadurch das zuvor ausgegebene Einschaltsignal 25 beendet. Der Empfänger 13 hat bei ungestörtem Funkempfang über eine Synchronisierleitung 26 die Phasenlage einer autonom-freilaufenden zeithaltenden Schaltung 27 synchronisiert, die nun die aktuell vom Empfänger 13 eingegebene Zeitinformation 16, für die fortlaufende weitere Darbietung mittels der Zeitanzeigeeinrichtung 18, weiterschaltet. Auf erneutes Betätigen des Reset-Schalters 19 bzw. periodisch, etwa bei Erreichen einer vollen Stunde, was im Zeit-Register 17 decodiert wird und zur Ausgabe eines Einschaltimpulses 28 führt, wird die Empfangseinrichtung wieder für die vorgegebene Zeitspanne T eingeschaltet, wenn nicht schon vor Ablauf dieser Zeitspanne T ein Empfangs-Bestätigungssignal 23 zur Wieder-Abschaltung der Empfangs-Einrichtung erscheint.A reset switch 19 is provided when it is operated manually, a reset signal 20 is triggered via a bistable circuit 21 the receiving device (i.e. the receiver 13 and if necessary switches on the decoder 14), those to save performance especially at a battery powered radio clock 11 normally turned off is. After a predetermined period of time T - represented in the drawing by a monostable or time circuit 22 -, or if the Radio reception utilizable time information 16 has delivered and therefore a receipt confirmation signal 23 appears, a switch-off pulse 24 generates the bistable circuit 21 in the initial state resets and thereby the previously output switch-on signal 25 ended. The recipient 13 has one with undisturbed radio reception Synchronization line 26, the phase position of an autonomously free-running synchronizing circuit 27, which is now the one currently entered by the receiver 13 Time information 16, for the continuous further presentation by means of the time display device 18, forwarded. By pressing the reset switch again 19 or periodically, for example when reaching one on the hour, which decodes in the time register 17 is and for the output of a switch-on pulse 28th leads, the receiving device is again for the predetermined time period T switched on, if not a receipt confirmation signal even before this time period T has elapsed 23 to switch off the The receiving device appears.

Das Reset-Signal 20 führt allerdings auch zu einem System-Reset des Prozessors 29, in dem die Funktionen des Decodierers 14 zur Lieferung der aktuell über Funk empfangenen Zeitinformation 16, des Zeit-Registers 17 zur Ansteuerung der Zeitanzeigeeinrichtung 18 und einer Koinzidenzschaltung 30 zur zeitabhängigen Auslösung weiterer zeitabgeleiteter Funktionen verwirklicht werden. Diese weiteren Funktionen können sich insbesondere auf die Ansteuerung wenigstens eines Terminsignalgebers 31 bei Erreichen eines Zeitpunktes beziehen, der mittels einer Handhabe 32 vorgebbar ist. Das bedeutet jedoch, daß auch die Information der Koinzidenzschaltung 30 gelöscht wird und deshalb keine nun an sich gegebenenfalls fällige Alarmgabe erfolgen kann, bzw. daß eine gerade eingesetzte Alarmgabe nicht mehr mit ihrem Alarmprogramm (wie etwa einer Snooze-Weckwiederholfunktion) ablaufen kann.However, the reset signal 20 also leads to a System reset of the processor 29 in which the Functions of the decoder 14 to deliver the current time information received via radio 16, des Time register 17 for controlling the time display device 18 and a coincidence circuit 30 for time-dependent triggering of further time-derived Functions are realized. These others Functions can particularly affect control at least one appointment signal generator 31 when reaching a point in time, which means a handle 32 can be predetermined. However, that means that also the information of the coincidence circuit 30 is deleted and therefore none in itself if necessary, alarm can be given, or that a currently used alarm is not more with their alarm program (such as one Snooze wake-up function).

Aus diesem Grunde wird der Reset-Schalter 19 zweckmäßigerweise so in die als Armbanduhr und/oder als Weckeruhr ausgestaltete Funkuhr 11 eingebaut, daß er nicht irrtümlich betätigt werden kann, etwa aufgrund eines Handhabungs-Reflexes aufgrund Auftretens eines Wecksignales oder aufgrund eines ungewollten Stoßes gegen eine Armbanduhr. Es ist ein Empfänger-Schalter 33 vorgesehen, dessen Betätigung - beim dargestellten Schaltungsbeispiel über einen weiteren ODER-Eingang der Zeit-Schaltung 22 - zur Auslösung eines Empfänger-Einschaltsignales 25 ohne gleichzeitigen Prozessor-Systemreset führ. Außerdem bewirkt die Betätigung dieses Schalters 33 über einen Speicher 35 und einen Umschalter 36 einen hier sogenannten Anzeige-Reset derart, daß die Zeitanzeigeeinrichtung 18 in eine definiert vorgegebene Referenzstellung gefahren wird, die mit der Referenzstellung bei Auftreten eines Prozessor-Reset übereinstimmen kann und beispielsweise in der Zeitanzeige 00:00:00 Uhr besteht. Die Funktion des Prozessors 29 bleibt aberzeithaltend beibehalten; d.h. es erfolgt beispielsweise bei Ansprechen der Koinzidenzschaltung 30 die Auslösung eines normalen, über einen Abstellschalter 37 beeinflußbaren Alarmgabeprogrammes.For this reason, the reset switch 19 expediently so as a wristwatch and / or radio clock 11 designed as an alarm clock, that it cannot be operated by mistake, for example due to a handling reflex Occurrence of a wake-up signal or due to a unintentional impact against a wristwatch. It is a receiver switch 33 provided, its operation - in the illustrated Circuit example over another OR input of the time circuit 22 - for triggering a receiver switch-on signal 25 without simultaneous processor system reset Furthermore causes this switch 33 to be actuated a memory 35 and a switch 36 one here so-called display reset such that the time display device 18 in a defined predetermined Reference position is moved with the reference position match when a processor reset occurs can and for example in the time display 00:00:00 exists. The function of the processor 29, however, remains intact; i.e. it takes place for example when the coincidence circuit responds 30 triggering a normal, over a Stop switch 37 influenceable alarm program.

Die durch Betätigung des Empfänger-Schalters 33 ausgelöste Reset-Ansteuerung der Zeitanzeigeeinrichtung 18 wird wieder aufgehoben, die Anzeigeeinrichtung 18 wieder zeitkorrekt aus dem Register 17 angesteuert, wenn entweder die Empfänger-Einschaltung erfolgreich war und neben der Decodierung einer aktuell über Funk empfangenen Zeitinformation 16 zum Erscheinen des Bestätigungssignales 23 führte; oder aber wenn nach einer vorgegebenen Zeitspanne T noch keine Empfangsinformation 15 decodiert werden konnte und deshalb zur Leistungseinsparung die Empfangseinrichtung zunächst einmal wieder vom Impuls 24 abgeschaltet wird.By pressing the receiver switch 33 triggered triggering of the time display device 18 is canceled again, the display device 18 correct from the register again 17 driven when either the receiver is turned on was successful and in addition to decoding a time information currently received by radio 16 for the appearance of the confirmation signal 23 led; or if according to a given Time period T has not yet decoded any reception information 15 could be and therefore for performance savings the receiving device first of all is switched off again by pulse 24.

Für den Benutzer einer Funkuhr 11 kann es, insbesondere wenn es sich um eine Alarmuhr handelt, von praktischem Interesse sein, zu wissen, wie gut gesichert die aktuell angezeigte Zeitinformation 16 im Vergleich zur über Funk empfangbaren Information 15 ist, d.h. wann die aktuell angezeigte Zeitinformation 16 zuletzt mit einer decodierbaren Empfangsinformation 15 abgeglichen wurde. Der kleinste Abgleich-Zyklus Z bestimmt sich danach, in welchen Abständen der vom Register 17 ausgelöste Schaltimpuls 28 erscheint, beispielsweise stündlich. Das davon, ODER vom manuell ausgelösten Zuschalt-Signal 34, hervorgerufene Empfänger-Einschaltsignal 25 steuert, über eine Unterbrecherschaltung 38 und eine Schaltstrecke 39, eine Kontrollanzeige 40 intermittierend an, um, zusätzlich zum Anzeige-Reset der Zeitanzeigeeinrichtung 18, zu signalisieren, daß momentan ein Empfangsversuch zur Aktualisierung der Zeitinformation 16 unternommen wird. Wenn der Empfangsversuch erfolgreich war oder nach der vorgegebenen Zeitspanne T erfolglos abgebrochen wird, wenn also das Einschaltsignal 25 verschwindet, wird auch die intermittierende Steuerung der Kontrollanzeige 40 wieder aufgehoben, und diese (beispielsweise eine digitale Flüssigkristallanzeige) vorzugsweise ganz abgeschaltet. Jedoch wird die Kontrollanzeige 40 wieder eingeschaltet - und zwar nun nicht intermittierend, sondern dauernd -, wenn ein vom Register-Einschaltimpuls 28 beaufschlagter Zykluszähler 41 aus seiner Nullstellung hochzählt, weil mindestens der erste über das Einschaltsignal 25 automatische ausgelöste Empfangsversuch nicht zu einer decodierbaren Empfangsinformation 15 führte. Die nun statisch dargebotene Zahl auf der Kontrollanzeige 40 gibt im dargestellten Beispielsfalle also an, wie viele (Stunden-)Zyklen bereits verstrichen sind, seit das letzte Mal die Zeitinformation 16 für die Zeitanzeigeeinrichtung 18 durch eine Empfangsinformation 15 bestätigt bzw. korrigiert werden konnte.For the user of a radio clock 11 it can, in particular if it is an alarm clock, be of practical interest to know how well saves the currently displayed time information 16 compared to the information that can be received via radio 15, i.e. when the currently displayed time information 16 last with decodable reception information 15 was compared. The smallest adjustment cycle Z is determined at what intervals the switching pulse triggered by register 17 28 appears, for example every hour. That of it OR from the manually triggered activation signal 34, caused receiver turn-on signal 25 controls, via an interrupt circuit 38 and a switching path 39, a control display 40 intermittently to, in addition to the display reset of the Time display device 18 to signal that currently a reception attempt to update the Time information 16 is undertaken. If the Attempt to receive was successful or according to the given Time period T is terminated unsuccessfully, if the switch-on signal 25 disappears, also the intermittent control of the control display 40 canceled, and this (for example a digital liquid crystal display) preferably completely switched off. However, the control display 40 switched on again - and now not intermittently, but continuously - if one of the register switch-on pulse 28 acted cycle counter 41 increments from its zero position because at least the first via the switch-on signal 25 automatic triggered reception attempt does not turn into a decodable Received information 15 led. The now statically presented number on the control display 40 in the example shown shows how many (Hourly) cycles have already passed since that last time the time information 16 for the time display device 18 by receiving information 15 could be confirmed or corrected.

Der Benutzer der Funkuhr 11 kann nun, um nicht den nächsten Zyklus bis zum Erscheinen wieder eines Einschaltsignales 25 abwarten zu müssen, über den Empfänger-Schalter 33 einen weiteren Empfangsverscuh auslösen, wie oben beschrieben. Der Zykluszähler 41 wird wieder in seine Zählanfangsstellung zurückgesetzt und damit die Kontrollanzeige 40 über die Schaltstrecke 39 abgeschaltet, sobald ein Empfangsversuch erfolgreich war, also zu einer decodierten Zeitinformation 16 und Ausgabe des Bestätigungssignales 23 geführt hat.The user of the radio clock 11 can now, in order not the next cycle until it appears again Waiting for switch-on signal 25 via the receiver switch 33 another Trigger reception delay as described above. The cycle counter 41 is again in its initial count position reset and thus the control display 40 switched off via the switching path 39, as soon as an attempt to receive was successful, so too decoded time information 16 and output of the confirmation signal 23.
