Bei einer batteriebetriebenen Uhr, z.B. einer Armbanduhr, einer Küchenuhr oder dergleichen, ist es nach einem Austausch der Batterie(n) häufig sehr mühsam, die aktuelle Uhrzeit und insbesondere das aktuelle Kalenderdatum wieder einzustellen. Dies gilt sowohl für analog anzeigende Uhren als auch in besonderem Maße für Uhren mit Digitalanzeige, wie z.B. mit Flüssigkristallanzeige. Selbst sogenannte Funkuhren, welche die aktuelle Uhrzeit und das kalendarische Datum selbsttätig nach Maßgabe eines empfangenen Funksignals einstellen, benötigen häufig sehr lange, bis die korrekten Zeit- und Datumsangaben abzulesen sind.In a battery-powered clock, such as a wristwatch, a kitchen clock or the like, it is often very tedious to replace the current time and in particular the current calendar date after replacing the battery (s). This applies to both analogue clocks as well as in particular for watches with digital display, such as with liquid crystal display. Even so-called radio clocks, which set the current time and the calendar date automatically in accordance with a received radio signal, often take a long time to read the correct time and date.

Während für die schnelle Einstellung einer Uhrzeit eine Vielzahl an Verfahren und Vorrichtungen bekannt sind, führen die bislang bekannten Verfahren bzw. Vorrichtungen nur selten zu einer rascheren Einstellung der Datumsanzeige.While a variety of methods and devices are known for the rapid setting of a time, the previously known methods or devices rarely lead to a faster setting of the date display.

Die Aufgabe der Erfindung besteht nunmehr darin, ein Verfahren und eine Vorrichtung zur Einstellung einer Datumsanzeige bei einer Funkuhr vorzustellen, bei dem bzw. bei der die Datumsanzeige nach einem Batteriewechsel in der Regel sehr schnell den tatsächlichen Kalendertag wiedergibt.The object of the invention is now to provide a method and apparatus for setting a date display in a radio clock, in which or at the date display after a battery change usually very quickly reflects the actual calendar day.

Diese Aufgabe wird durch ein Verfahren zur Einstellung einer Datumsanzeige bei einer Uhr mit den Merkmalen des Patentanspruchs 1 sowie durch eine Vorrichtung mit den Merkmalen des Patentanspruchs 7 erfindungsgemäß gelöst.This object is achieved by a method for setting a date display in a clock with the features of claim 1 and by a device having the features of claim 7 according to the invention.

Vorteilhafte Ausführungen und Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments and further developments of the invention are specified in the subclaims.

Das erfindungsgemäße Verfahren zur Einstellung einer Datumsanzeige umfasst folgende nacheinander ablaufende automatischen Verfahrensschritte:

  1. a. Feststellen, dass ein Batteriewechsel notwendig ist
  2. b. Verbringen der Datumsanzeige in eine vorbestimmte Referenzposition, nachdem die Notwendigkeit eines Batteriewechsels festgestellt worden ist
  3. c. Feststellen, dass ein Batteriewechsel stattgefunden hat
  4. d. Feststellen des an der Datumsanzeige aktuell einzustellenden Datums, nachdem eine neue Batterie eingelegt wurde, und
  5. e. Einstellen des festgestellten aktuell einzustellenden Datums an der Datumsanzeige ausgehend von der Referenzposition, in die die Datumsanzeige verbracht wurde, nachdem die Notwendigkeit eines Batteriewechsels festgestellt wurde.
The method according to the invention for setting a date display comprises the following successive automatic method steps:
  1. a. Determine that a battery change is necessary
  2. b. Moving the date display to a predetermined reference position after the need for battery replacement has been determined
  3. c. Determine that a battery change has occurred
  4. d. Determine the date to be set on the date display after a new battery has been inserted, and
  5. e. Setting the detected date currently set on the date display from the reference position to which the date display was spent after the need for a battery change was detected.

Um dieses Verfahren durchführen zu können, bedarf es einer Vorrichtung mit folgenden Einzelkomponenten:

  1. a) Mittel zum automatischen Feststellen der Notwendigkeit eines Batteriewechsels,
  2. b) Mittel zum automatischen Verbringen der Datumsanzeige in eine vorbestimmte Referenzposition,
  3. c) Mittel zum automatischen Feststellen, dass ein Batteriewechsel stattgefunden hat,
  4. d) Mittel zum automatischen Feststellen des an der Datumsanzeige aktuell einzustellenden Datums sowie
  5. e) Mittel zum automatischen Einstellen des festgestellten Datums an der Datumsanzeige ausgehend von der Referenzposition
In order to carry out this procedure, a device with the following individual components is required:
  1. a) means for automatically determining the need for a battery change,
  2. b) means for automatically moving the date display to a predetermined reference position,
  3. c) means for automatically determining that a battery change has occurred;
  4. d) means for automatically determining the date to be set at the date display as well as
  5. e) means for automatically setting the detected date on the date display from the reference position

Es ist bekannt, dass die Batteriespannung mit zunehmender Entladung abnimmt. Die Notwendigkeit eines Batteriewechsels deutet sich beispielsweise dann an, wenn die Spannung der Batterie unterhalb einen vorgegebenen Spannungswert gefallen ist. Erfindungsgemäß ist daher vorgesehen, dass die Mittel zum Feststellen der Notwendigkeit eines Batteriewechsels eine Messeinrichtung umfassen, welche die Batteriespannung unter Belastung misst. Wird festgestellt, dass die Batteriespannung unter einem vorbestimmten Wert liegt, wird dies einer zentralen Steuereinheit signalisiert, welche veranlasst, dass die Datumsanzeige (z.B. ein mechanisch drehendes Rad mit den Tageszahlen "1" bis "31" oder den Wochentagen "Mo, Di, Mi, Do, Fr, Sa, So") in die vorbestimmte Referenzstellung überführt wird.It is known that the battery voltage decreases with increasing discharge. The need for a battery change, for example, indicates when the voltage of the battery has fallen below a predetermined voltage value. According to the invention, it is therefore provided that the means for determining the need for a battery replacement comprise a measuring device which measures the battery voltage under load. If it is determined that the battery voltage is below a predetermined value, this is signaled to a central control unit, which causes the date display (eg a mechanically rotating wheel with the day numbers "1" to "31" or the weekdays "Mon, Tue, Wed , Thu, Fri, Sat, Sun ") is transferred to the predetermined reference position.

Aufschluss über den Ladezustand der Batterie gibt beispielsweise im Falle einer analog anzeigenden Uhr mit von einem oder mehreren Schrittmotoren angesteuerten Zeigerwerk die Exaktheit der Nachführung der Zeiger infolge der zur Zeigerbewegung erforderlichen Ansteuerpulse für den bzw. die Schrittmotor(en). Mit zunehmender Entladung sind vermehrt Ansteuerpulse zur Korrektur der Zeigerposition oder Ansteuerimpulse mit abweichender Impulsform erforderlich, um die Zeiger der Uhr in die gewünschte Stellung zu verbringen. Die Analyse dieser zur Ansteuerung der Zeiger bzw. zum Betrieb eines oder mehrerer diese Zeiger antreibenden Motors bzw. Motoren kann daher ebenfalls zur Indikation der Notwendigkeit eines Batteriewechsels verwendet werden.Information about the state of charge of the battery is, for example, in the case of an analog clock indicating controlled by one or more stepping motors pointer accuracy of tracking the pointer due to the required for the pointer movement drive pulses for the stepper motor (s). With increasing discharge are increasingly driving pulses for correcting the pointer position or drive pulses with deviating Pulse shape required to move the hands of the watch to the desired position. The analysis of these for driving the pointer or for operating one or more of these pointer driving motor or motors can therefore also be used to indicate the need for a battery change.

Erfindungsgemäß können die Mittel zum Feststellen der Notwendigkeit eines Batteriewechsels daher anstelle oder zusätzlich zur vorstehend beschriebenen Spannungsüberwachungseinrichtung eine Auswerteeinrichtung umfassen, welche von für einen Motorantrieb notwendige Ansteuerimpulse auswertet. Wird festgestellt, dass die Ansteuerimpulse auf zunehmende Probleme bei der korrekten Zeigerpositionierung hinweisen, wird dies der zentralen Steuereinheit signalisiert, welche veranlasst, dass die Datumsanzeige in die vorbestimmte Referenzstellung überführt wird.According to the invention, the means for determining the need for a battery replacement may therefore comprise, instead of or in addition to the voltage monitoring device described above, an evaluation device which evaluates drive pulses necessary for a motor drive. If it is determined that the drive pulses indicate increasing problems with the correct pointer positioning, this is signaled to the central control unit, which causes the date display to be transferred to the predetermined reference position.

Erfindungsgemäß ist ein (z.B. elektronischer oder mechanischer) Speicher vorgesehen, in dem die vorbestimmte Referenzposition hinterlegt ist.According to the invention, a memory (e.g., electronic or mechanical) is provided in which the predetermined reference position is stored.

Um sicherzustellen, dass die Wiedereinstellung von Uhrzeit und Datum erst nach einem Batteriewechsel erfolgt und nicht etwa solange die alte Batterie noch eingelegt ist, muss (vorzugsweise zweifelsfrei) festgestellt werden, dass die alte Batterie durch eine neue ersetzt wurde. Die Feststellung, ob es sich bei der eingelegten Batterie um eine neue handelt, lässt sich wiederum über die Messung des Ladezustands der eingelegten Batterie feststellen.To ensure that the re-setting of time and date does not take place until after the battery has been changed and not while the old battery is still inserted, it must be ascertained (preferably unequivocally) that the old battery has been replaced by a new one. The determination of whether the inserted battery is a new, can be found again by measuring the state of charge of the inserted battery.

Erfindungsgemäß umfassen die Mittel zum Feststellen, dass ein Batteriewechsel stattgefunden hat, eine Messeinrichtung, welche die Batteriespannung unter Belastung misst. Weitere Details zum Ablauf der Auswertung und Steuerung entnimmt man obiger Beschreibung.According to the invention, the means for determining that a battery change has taken place comprise a measuring device which measures the battery voltage under load. Further details on the sequence of evaluation and control takes from the above description.

Alternativ oder zusätzlich können die Mittel zum Feststellen, dass ein Batteriewechsel stattgefunden hat, auch eine Auswerteeinrichtung umfassen, welche von für einen Motorantrieb notwendige Ansteuerimpulse auswertet. Weshalb sich eine derartige . Auswerteeinrichtung zur Bestimmung des Ladezustands der Batterie eignet, wurde vorstehend im Detail beschrieben, ebenso wurden Einzelheiten zur Auswertung und Steuerung dargelegt.Alternatively or additionally, the means for determining that a battery change has taken place may also comprise an evaluation device which evaluates drive pulses necessary for a motor drive. Why is such a. Evaluation device for determining the state of charge of the battery is suitable, has been described in detail above, as well as details were presented for evaluation and control.

Es gibt nunmehr verschiedene Möglichkeiten, das nach dem Batteriewechsel an der Datumsanzeige einzustellende Datum festzustellen bzw. vorzugeben. Handelt es sich bei der Uhr um eine sogenannte Funk(armband)uhr, so umfassen die Mittel zum Feststellen des an der Datumsanzeige aktuell einzustellenden Datums vorzugsweise eine Empfangseinrichtung, welche ein von einem Zeitzeichensender gesendetes Zeitsignal (z.B. das von der physikalisch technischen Bundesanstalt in Braunschweig gesendete DCF77-Zeitsignal; DCF77 setzt sich aus dem Buchstaben D für Deutschland, dem C als Kennzeichen eines Langwellensenders und dem F wegen der Nähe zu Frankfurt -der Sendeort Mainflingen liegt nahe bei Frankfurt- zusammen) empfängt. Anhand dieses empfangenen Zeitsignals, welches auch das momentane Datum enthält, lässt sich das aktuelle Datum ermitteln und nachfolgend an der Uhr einstellen.There are now various ways to determine or specify the date to be set after the battery change date on the date. If the watch is a so-called radio (wristband) watch, then the means for determining the date to be currently set on the date display preferably comprises a receiving device which transmits a time signal transmitted by a time signal transmitter (eg that sent by the physically technical Federal Institute in Braunschweig DCF77 is composed of the letter D for Germany, the C as a characteristic of a long-wave transmitter and the F because of the proximity to Frankfurt-the transmission location Mainflingen is located near Frankfurt- together receives). On the basis of this received time signal, which also contains the current date, the current date can be determined and subsequently set on the clock.

Anstelle der Uhrkrone 9 könnte auch eine Druckknopf- oder eine Stelleinrichtung sonstiger Art vorgesehen sein, um die Zeiger 6, 7, 8 und die Datumsanzeige 10, 11 auf die gewünschte Zeit bzw. das gewünschte Datum einzustellen.In likewise per se conventional design, a crown 9 is present in order to adjust the position of the hands 6, 7, 8 and the date display 10, 11 can. Instead of the crown 9, a push button or a setting device of any other kind could be provided to adjust the hands 6, 7, 8 and the date display 10, 11 to the desired time or the desired date.

Innerhalb des Uhrgehäuses 12 ist eine elektronische Steuereinrichtung 17 der in der Figur 1 gezeigten Art angeordnet. Diese elektronische Steuereinrichtung 17 dient zum einen zum Empfang von Zeitzeichensignalen, zum Einstellen von Datum und Uhrzeit sowie zur Überwachung des Ladezustandes einer Batterie oder eines Akkumulators.Within the watch case 12 is an electronic control device 17 in the FIG. 1 arranged type arranged. This electronic control device 17 serves for a reception of time signal signals, for setting the date and time and for monitoring the state of charge of a battery or a rechargeable battery.

Die elektronische Steuereinrichtung 17 gemäß der Figur 1 umfasst eine Batterie 1, um die elektronischen Schaltkreise der Steuereinrichtung 17 mit elektrischer Energie zu versorgen. Weiterhin sind mehrere Motoren 18 zum Antrieb der Zeiger 6, 7, 8 und der eine Wochentagesanzeige 10 und eine Tagesanzeige 11 umfassenden Datumsanzeige vorgesehen. Zum Antrieb der Motoren 18 für die Zeiger 6, 7, 8 und die Datumsanzeige 10, 11 ist eine Stelleinrichtung 14 vorhanden, welche elektrisch mit den vorstehend genannten Bestandteilen 18 verbunden ist. Weiterhin ist eine Empfangseinrichtung zum Empfang von Zeitzeichensignalen vorhanden. Im vorliegenden Ausführungsbeispiel ist diese Empfangseinrichtung durch eine mit dem Bezugszeichen 16 gekennzeichnete Antenne symbolisiert. Es ist eine Batteriespannungsmesseinrichtung 2 vorgesehen, welche den Ladezustand der Batterie 1, insbesondere im belasteten Zustand, fortlaufend misst. Eine Motorimpulsauswerteeinrichtung 3 ist dazu vorgesehen, das Bewegungsverhalten der Motoren 18 für die Zeiger 6, 7, 8 bzw. die Datumsanzeige 10, 11 anhand der für eine Bewegung der Motoren 18 notwendigen Motorimpulse festzustellen. Schließlich ist eine Speichereinrichtung vorhanden, welche insbesondere dazu dient, eine bestimmte Stellung der Rädchen der Datumsanzeige 10, 11 als Referenzstellung zu speichern.The electronic control device 17 according to the FIG. 1 includes a battery 1 to provide the electronic circuits of the controller 17 with electrical energy. Furthermore, a plurality of motors 18 for driving the hands 6, 7, 8 and a weekday display 10 and a day display 11 comprehensive date display are provided. To drive the motors 18 for the pointers 6, 7, 8 and the date display 10, 11, an adjusting device 14 is present, which is electrically connected to the aforementioned components 18. Furthermore, a receiving device for receiving time signal signals is present. In the present embodiment, this receiving device is symbolized by a designated by the reference numeral 16 antenna. A battery voltage measuring device 2 is provided which continuously measures the state of charge of the battery 1, in particular in the loaded state. A Motorimpulsauswerteinrichtung 3 is provided to determine the movement behavior of the motors 18 for the pointer 6, 7, 8 and the date display 10, 11 based on the motor pulses necessary for a movement of the motors 18. Finally, a memory device is provided, which serves in particular to store a specific position of the wheels of the date display 10, 11 as a reference position.

Erfindungsgemäß arbeitet die elektronische Steuereinrichtung 17 nach folgendem Schema:

  • Die Batteriespannungsmesseinrichtung 2 sowie die Motorimpulsauswerteeinrichtung 3 überwachen direkt (Batteriespannungsmesseinrichtung 2) bzw. indirekt (Motorimpulsauswerteeinrichtung 3) den Ladezustand der Batterie 1. Stellt z.B. die Batteriespannungsmesseinrichtung 2 fest, dass die Batteriespannung der Batterie 1 um einen gewissen Betrag unterhalb der Nennbatteriespannung liegt, so signalisiert diese Batteriespannungsmesseinrichtung 2 der Stelleinrichtung 14 die Notwendigkeit eines Batteriewechsels. Alternativ oder zusätzlich wertet die Motorimpulsauswerteeinrichtung 3 die für eine Bewegung der Motoren 18 notwendigen Strompulse aus. Stellt die Motorimpulsauswerteeinrichtung 3 beispielsweise fest, dass für eine bestimmte Motorbewegung die Zahl der notwendigen Strompulse eine vorgegebene Nennpulszahl übersteigt, so gibt die Motorimpulsauswerteeinrichtung 3 diese Information an die Stelleinrichtung 14 weiter.
According to the invention, the electronic control device 17 operates according to the following scheme:
  • The battery voltage measuring device 2 and the motor pulse evaluation device 3 monitor directly (battery voltage measuring device 2) or indirectly (motor pulse evaluation device 3) determines the state of charge of the battery 1. If, for example, the battery voltage measuring device 2 determines that the battery voltage of the battery 1 is below the nominal battery voltage by a certain amount, this battery voltage measuring device 2 signals the setting device 14 the need for a battery change. Alternatively or additionally evaluates the Motorimpulsauswerteeinrichtung 3 necessary for a movement of the motors 18 current pulses. If the motor pulse evaluation device 3 determines, for example, that the number of necessary current pulses exceeds a predetermined nominal pulse number for a specific motor movement, the motor pulse evaluation device 3 transmits this information to the actuating device 14.

Nachdem nunmehr die Elektronik die entsprechende Batteriefehlspannung festgestellt hat, veranlasst die Stelleinrichtung 14, dass die Kalenderanzeige 10, 11 auf eine vorbestimmte Position gefahren wird. Diese Position ist in dem Speicher 15 abgelegt. Die Datumsanzeige 10, 11 verbleibt nunmehr in dieser Position, bis ein Batteriewechsel vorgenommen wurde.Now that the electronics has detected the corresponding battery leakage, causes the actuator 14 that the calendar display 10, 11 is moved to a predetermined position. This position is stored in the memory 15. The date display 10, 11 now remains in this position until a battery change has been made.

Die Vornahme eines Batteriewechsels kann beispielsweise mit Hilfe der Batteriespannungsmesseinrichtung 2 festgestellt werden, nämlich dadurch, dass die Batteriespannung auch unter Belastung über einem Schwellwert verbleibt. Dieser Schwellwert kann z.B. ein gewisser Betrag über der Nennspannung der Batterie 1 liegender Spannungswert sein.The making of a battery change can be detected, for example, with the aid of the battery voltage measuring device 2, namely the fact that the battery voltage remains above a threshold even under load. This threshold may e.g. be a certain amount above the nominal voltage of the battery 1 lying voltage value.

Alternativ oder zusätzlich kann ein Batteriewechsel auch dadurch festgestellt werden, dass die Motorimpulsauswerteeinrichtung 3 detektiert, dass die Zahl der zur Bewegung der Zeiger 6, 7, 8 und/oder der Datumsanzeige 10, 11 notwendigen Strompulse unter einem vorgegebenen Schwellwert verbleiben. Beide Informationen werden im vorliegenden Ausführungsbeispiel an die Stelleinrichtung 14 übermittelt.Alternatively or additionally, a battery change can also be detected by the motor pulse evaluation device 3 detecting that the number of current pulses necessary for moving the hands 6, 7, 8 and / or the date display 10, 11 remains below a predetermined threshold value. Both information is transmitted to the adjusting device 14 in the present embodiment.

Wird nunmehr über die Antenne 16 und die entsprechende Empfangseinrichtung ein Zeitzeichensignal empfangen, kann die Datumsanzeige 10, 11 aus der im Speicher 15 hinterlegten und zuvor eingestellten Referenzstellung auf die aktuelle Kalendertagesanzeige gebracht werden.If a time signal is now received via the antenna 16 and the corresponding receiving device, the date display 10, 11 can be brought from the stored in the memory 15 and previously set reference position on the current calendar day display.
