Abstract

An automatic setting system is used to maintain correct local time for watches that are worn irrespective of the wearer's locations. A precise standard reference time generator, such as the one is Germany, transmits a signal by satellite. The satellite system is linked to an absolute navigational position location function. The receiver in the watch adjusts to the local reference time. USE/ADVANTAGE - Provides automatic adjustment to precise local time.

Description

Die herkömmlichen Uhren mit ihren komplizierten mechanischen Uhrwerken sind weitge­ hend durch elektronische Uhren ersetzt worden, die mit einer elektrischen Energiequelle und einem hochgenauen Schwingquarz arbeiten.The conventional watches with their complicated mechanical movements are wide has been replaced by electronic clocks with an electrical energy source and work with a high-precision quartz crystal.

Um eine noch präzisere Zeitanzeige zu gewährleisten, ist es bekannt, von Sendern abgege­ bene Zeitsignale zu verwenden. In Deutschland befindet sich ein solcher Sender bei Main­ flingen, der seine Zeitsignale von einer Cäsium-Atomuhr erhält, die in der Physikalisch­ technischen Bundesanstalt in Braunschweig steht. Die Zeitabweichungen dieser Atom-Uhr betragen etwa 1 Sekunde in 1 Million Jahren.In order to ensure an even more precise time display, it is known to transmit from transmitters to use the same time signals. In Germany, such a station is located at Main flingen, which receives its time signals from a cesium atomic clock, which in the physical federal technical institute in Braunschweig. The time deviations of this atomic clock are about 1 second in 1 million years.

Seit einiger Zeit sind auch Armbanduhren auf dem Markt, die im Armband (Junghans) oder auf dem Ziffernblatt (Citizen) eine Antenne besitzen, welche für den Empfang der Zeitsignale des Mainflinger Senders geeignet sind. Diese Uhren sind zumeist übliche Quarzuhren, die jedoch von Zeit zu Zeit durch die Mainflinger Zeitsignale "gestellt" wer­ den.For some time there have also been wristwatches on the market that are in the bracelet (Junghans) or have an antenna on the dial (Citizen), which is used to receive the Time signals from the Mainflinger transmitter are suitable. These watches are mostly common Quartz clocks, which are "put" by the Mainflinger time signals from time to time the.

Ein Problem, das sich bei der ortsbeweglichen Armbanduhr ergibt, liegt in dem Umstand begründet, daß es z. B. in Australien, Japan oder in den USA keine Sender gibt, die auf derselben Frequenz wie der Mainflinger Sender Zeitsignale aussenden. In Gebieten, die mehr als 2000 km von Mainflingen entfernt sind, können die Mainflinger Signale nicht mehr empfangen werden. Damit verlieren die Uhren in diesen Gebieten ihren Wert.One problem that arises with the portable wristwatch is that justifies that z. B. in Australia, Japan or the United States there are no stations on transmit time signals at the same frequency as the Mainflinger transmitter. In areas that Mainflingen signals cannot be more than 2000 km away from Mainflingen  more to be received. As a result, watches in these areas lose their value.

Es gibt auch schon Uhren, welche neben den Mainflinger Zeitsignalen auch schon die an­ dersartigen Zeitsignale in den USA verarbeiten können, doch sind auch diese Uhren nicht in der Lage, z. B. in Australien die Zeitanzeige nach Funk-Signalen auszurichten.There are also clocks which, in addition to the Mainflinger time signals, also indicate that can process such time signals in the USA, but these clocks are also not able e.g. B. in Australia to align the time display according to radio signals.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Uhr zu schaffen, welche an jedem Ort der Erde nach Funksignalen ausgerichtet werden kann.The invention is therefore based on the object of creating a watch which is suitable for everyone Location of the earth can be aligned to radio signals.

Diese Aufgabe wird gemäß den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved in accordance with the features of patent claim 1.

Der mit der Erfindung erzielte Vorteil besteht insbesondere darin, daß es möglich ist, an je­ dem Ort der Erde die exakte Zeit per Satellitensignal einzustellen. Ein weiterer Vorteil der Erfindung besteht darin, daß auch die Zeitverschiebungen zwischen den einzelnen Orten berücksichtigt werden können. Durch Verwendung einer Ortsbestimmungsschaltung, wie sie in der modernen Seeschiffahrt üblich sind, kann die exakte Ortszeit eingestellt werden. Diese Einstellung der Ortszeit ist auch dann möglich, wenn die eigentliche Zeit nicht per Satellitenfunk eingestellt wird, d. h. auch bei den üblichen Quarzuhren können die Zeitver­ schiebungen berücksichtigt werden.The advantage achieved with the invention is in particular that it is possible to each to set the exact time via satellite signal to the location of the earth. Another advantage of Invention is that time shifts between locations can be taken into account. By using a location determining circuit, such as If they are common in modern maritime shipping, the exact local time can be set. This setting of the local time is also possible if the actual time is not via Satellite radio is set, d. H. Even with the usual quartz watches, the time ver shifts are taken into account.

Fliegt jemand beispielsweise von Frankfurt nach New York, so erkennt die Uhr den Ort New York durch Satelliten-Peilung und stellt die Frankfurter Zeit um 6 Stunden zu­ rück. Auf diese Weise ist es möglich, an jedem Ort der Erde die richtige Ortszeit anzuzei­ gen. Der Ort selbst kann ebenfalls - etwa mittels einer alphanumerischen Flüssigkristallan­ zeige - optisch dargestellt werden. Die einfachste, wenn auch etwas unanschauliche Dar­ stellungsart ist die Anzeige der Längen- und Breitengrade des jeweiligen Orts. Durch einen ROM-Speicher könnten diese Längen- und Breitengrade bestimmten Orten zugeordnet und angezeigt werden.For example, if someone flies from Frankfurt to New York, the watch will recognize them Location New York by satellite bearing and delivers the Frankfurt time by 6 hours return In this way it is possible to display the correct local time anywhere in the world The location itself can also - for example by means of an alphanumeric liquid crystal show - be presented optically. The simplest, if somewhat unclear, Dar Position type is the display of the longitude and latitude of the respective location. Through a ROM memories could map these latitudes and longitudes to specific locations are displayed.
