Abstract

The standard time transmission reception device uses a reception circuit integrated in the watch, comprising a reception antenna with a coil and a ferrite core and a capacitor. The ferrite core is provided by the housing of the watch, which is made of a ferrite material, shaped in accordance with the design of the watch and enclosed by a thin outer sheathing which does not affect the reception characteristics. Pref the ferrite material acts as the support element for the mechanical and electrical components of the reception device. ADVANTAGE - Integrated within watch without increasing its overall size.

Description

Die Erfindung betrifft eine Einrichtung zum Empfang eines Normalzeit­ senders in Armband- oder Taschenuhren nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for receiving a normal time transmitter in wrist or pocket watches according to the generic term of Claim 1.

Eine solche Empfangseinrichtung ist aus der Gebrauchsmuster-Veröffentlichung DE 88 15 967 U1 bekannt.Such a receiving device is off the utility model publication DE 88 15 967 U1 known.

Empfangssysteme für Normalzeitsender sind seit längerer Zeit in Gebrauch. Die Konsumgüterindustrie bietet preiswerte Uhren für den Empfang von Normalzeitsendern an.Receiving systems for standard time transmitters have been around for a long time in use. The consumer goods industry offers inexpensive Clocks for the reception of standard time stations.

Bei diesen Systemen handelt es sich um Geradeaus- oder Überla­ gerungsempfänger, die für eine Aufbereitung des Normalzeitsignals sorgen. Nachgeschaltet ist ein Prozessor, der zur Synchronisation und Ablaufsteuerung der Uhr dient.These systems are straight or overload gage receiver, for the preparation of the normal time signal to care. A processor is connected downstream Synchronization and sequence control of the clock is used.

Für den Empfang des Normalzeitsignals sind die Empfänger selektiv ausgebildet, da einerseits eine diskrete Frequenz ausgewertet werden muß und andererseits gegenüber Fremdsignalen eine hohe Selektion erforderlich ist.The receivers are responsible for receiving the normal time signal selectively trained, because on the one hand a discrete frequency must be evaluated and on the other hand against external signals a high selection is required.

Übliche Daten dieser Empfänger sind Verstärkungen von ca. 120 dB und AGC-Regelungen von ca. 100 dB, um im Nah- und Fernbereich eines Normalzeitsenders einen auswertbaren Empfang zu gewährleisten.Typical data from these receivers are gains of approx. 120 dB and AGC regulations of approx. 100 dB, in the near and far range a normal time transmitter to an evaluable reception guarantee.

Ein wesentlicher Bestandteil dieser Normalzeitempfänger ist der Antennenschwingkreis. Hierzu dient ein Parallelschwingkreis, der auf die Empfangsfrequenz abgeglichen ist und ein Signal in Abhängigkeit der Eingangsfeldstärke an den Eingangsverstärker abgibt, wobei die Induktivität des Parallelschwingkreises, wie in der Rundfunktechnik üblich, als Spule mit Ferritkern ausgebildet ist. An essential part of these normal time receivers is the Antenna resonant circuit. A parallel resonant circuit is used for this, which is tuned to the reception frequency and a signal in Dependence of the input field strength on the input amplifier emits, the inductance of the parallel resonant circuit, such as common in broadcast technology, is designed as a coil with ferrite core.  

Da nach heutigem Stand der Technik Empfänger und Ablaufsteue­ rung der Uhr durch Integration miniaturisiert werden können, liegt das Problem bei dem Empfang von Normalzeitsignalen für Armband- oder Taschenuhren in der konstruktiven Anpassung des Eingangsschwingkreises, im besonderen des Ferritkerns der Antenne an die Uhr.Because according to the current state of the art receiver and process tax clock can be miniaturized by integration, the problem is with the reception of normal time signals for Wrist or pocket watches in the constructive adaptation of the Input resonant circuit, in particular the ferrite core of the antenna to the clock.

Bei der Empfangseinrichtung nach der eingangs genannten Veröffentlichung ist die Ferritantenne als von einem flexiblen Kern durchsetzte Spule ausgebildet. Durch die Flexibilität des Kerns ist der Einbau in vorhan­ dene Aufnahmeräume erleichtert. Allerdings ist in kleinen Uhren dieser Aufnahmeraum, wenn über­ haupt in ausreichendem Umfang vorhanden, knapp bemessen. Aus diesem Grunde ist gemäß der Ver­ öffentlichung bei Armbanduhren vorgesehen, die Ferritantenne in das Uhrenarmband zu integrieren, dies bedingt eine weitgehend feste Zusammengehö­ rigkeit von Uhr und Armband.In the receiving device according to the above Release is the ferrite antenna as from one flexible core interspersed coil formed. By the flexibility of the core is the installation in existing relieved recording rooms. However, in small clocks this recording room when over sufficient at all, scarce dimensioned. For this reason, according to Ver publication provided for wristwatches that Integrate ferrite antenna into the watch band, this requires a largely solid togetherness watch and bracelet.

Aufgabe der Erfindung ist es, den Raumbedarf für die Antenne noch weiter zu verringern.The object of the invention is the space requirement for the antenna to decrease even further.

Diese Aufgabe wird durch die im Patentanspruch 1 angegebene Erfindung gelöst.This object is achieved by the in claim 1 specified invention solved.

Besondere Ausführungsarten der Erfindung sind in den Unteransprüchen angegeben.Special embodiments of the invention are specified in the subclaims.

Weitere Einzelheiten ergeben sich aus einem Ausführungsbeispiel nach Fig. 1.Further details result from an exemplary embodiment according to FIG. 1.

Fig. 1a zeigt eine Armbanduhr wobei in Fig. 1b das Ferrit­ material für die Antenne dem Äußeren der Uhr angepaßt ist. Die zwei Kreis- oder Polygonsegmente, die in der Mitte verbunden sind, werden von der Wicklung des Antennenschwing­ kreises umschlossen. Fig. 1a shows a wristwatch in which in Fig. 1b the ferrite material for the antenna is adapted to the outside of the watch. The two circular or polygon segments, which are connected in the middle, are enclosed by the winding of the antenna oscillating circuit.

Wie aus Fig. 1c ersichtlich, ist die erforderliche Leiterplatte mit Empfangsteil des Zeitzeichensignals und Auswerteelektronik dem Ferritmaterial so angepaßt, daß diese als tragendes Konstruktionselement für die Leiterplatte dient.As can be seen from Fig. 1c, the required circuit board with the receiving part of the time signal and evaluation electronics is adapted to the ferrite material so that it serves as a supporting structural element for the circuit board.

Da sich Empfangselektronik und Antenne in unmittelbarer Nähe befinden, ist es erforderlich, Regelung und Verstärkung des Normalszeitsignals so zu verteilen, daß Rückkopplungen auf die Antenne vermieden werden.Because the receiving electronics and antenna are in close proximity located, it is necessary to regulate and reinforce the Distribute normal time signal so that feedback on the antenna can be avoided.

Dies läßt sich durch einen Überlagerungsempfänger mit Verstär­ kungsverteilung und Verstärkungsregelung in der Zwischenfrequenz erreichen.This can be done with an overlay receiver with amplifiers distribution and gain control in the intermediate frequency to reach.

Günstige Layoutauslegung, Verwendung von ungehäusten IC's mit kürzesten Zuleitungen und eine doppelseitige Leiterplatte mit GND-plane tragen weiterhin zur Empfangsstabilität bei.Favorable layout design, use of unhoused IC's shortest leads and a double-sided circuit board with GND tarpaulins continue to contribute to reception stability.
