Description

Funktelefon mit einer integrierten UhrRadiotelephone with an integrated clock
Die Erfindung betrifft ein Funktelefon mit einer inte- grierten Uhr.The invention relates to a radio telephone with an integrated clock.
Herkömmliche Funktelefone, wie zum Beispiel im zellularen Netz betriebene Mobiltelefone oder im lokalen Netz betriebene Schnurlostelefone haben üblicherweise keine interne Uhr. Sofern eine interne Uhr in das Funktelefon integriert ist, wird hierbei eine quarzgesteuerte Uhr realisiert, deren Genauigkeit durch die benutzten Bauelemente, insbesondere durch den Uhrenquarz begrenzt ist. Das Einstellen der Uhr muß manuell erfolgen. Um zu vermeiden, daß die Uhr nach einem Auswechseln des Versorgungsakkus für das Funktelefon oder nach einem vollständigen Entladen des Versorgungsakkus wieder neu eingestellt werden muß, ist eine zusätzliche Batterie für den Betrieb der Uhr erforderlich. Hierfür werden Knopfzellen eingesetzt, wodurch der Preis des Funktelefons steigt, die Funktion der Uhr durch die Haltbarkeit der Knopfzelle bestimmt wird, sowie Probleme und Kosten bei der Entsorgung alter Funktelefone auftreten.Conventional radio telephones, such as mobile telephones operated in the cellular network or cordless telephones operated in the local network, usually do not have an internal clock. If an internal clock is integrated in the radio telephone, a quartz-controlled clock is implemented, the accuracy of which is limited by the components used, in particular by the clock quartz. The clock must be set manually. In order to prevent the clock from having to be reset after a replacement of the supply battery for the radio telephone or after a complete discharge of the supply battery, an additional battery is required for the operation of the clock. Button cells are used for this purpose, which increases the price of the radio telephone, the function of the watch is determined by the durability of the button cell, and problems and costs arise in the disposal of old radio telephones.
Zur Lösung dieser Probleme wird ein Funktelefon mit einer integrierten Uhr vorgeschlagen, das einen Funkuhrempfänger zum Empfangen und Auswerten eines Synchro- nisationszeitsignals für die integrierte Uhr hat.To solve these problems, a radio telephone with an integrated clock is proposed, which has a radio clock receiver for receiving and evaluating a synchronization nization time signal for the integrated clock.
Das Funktelefon wird somit dahingehend erweitert, daß es einen Echtzeitsender, zum Beispiel den Sender DCF77 der Physikalisch-Technischen Bundesanstalt Braunschweig, empfangen und auswerten kann. Hierdurch kann die integrierte Uhr selbstätig synchronisiert und eingestellt werden, so daß keine Zusatzbatterie zum Aufrechterhalten des Uhrenbetriebs mehr erforderlich ist. Möglicherweise zu beachtende Zeitzonenverschiebungen lassen sich durch Eingabe eines zeitlichen Offsets bei der Anzeige der Uhrzeit berücksichtigen.The radio telephone is thus expanded so that it can receive and evaluate a real-time transmitter, for example the transmitter DCF77 from the Physikalisch-Technische Bundesanstalt Braunschweig. As a result, the integrated clock can be synchronized and set automatically, so that no additional battery is required to maintain clock operation. Time zone shifts that may need to be taken into account can be taken into account by entering a time offset when displaying the time.
Das Funktelefon hat vorteilhafterweise eine quarzge- steuerte integrierte Uhr, die durch den Funkuhrempfänger und eine Steuerungseinrichtung mit Hilfe der empfangenen und ausgewerteten Synchronisationszeitsignale des Echtzeitsenders synchronisiert wird. Die Synchronisation erfolgt vorteilhafterweise in festgelegten Zeit- intervallen und insbesondere nach dem Einschalten desThe radio telephone advantageously has a quartz-controlled integrated clock which is synchronized by the radio clock receiver and a control device with the aid of the received and evaluated synchronization time signals from the real-time transmitter. The synchronization advantageously takes place at fixed time intervals and in particular after the
Funktelefons und/oder nach dem vollständigen Entladen des Versorgungsakkus für das Funktelefon bzw. dem Anklemmen eines neuen Versorgungsakkus an das Funktelefon, nachdem das Funktelefon eine Zeitlang ohne eine Spannungsversorgung war.Radio telephones and / or after the supply battery for the radio telephone has been completely discharged or a new supply battery has been connected to the radio telephone after the radio telephone has been without a power supply for a while.
Der Funkuhrempfänger besteht aus einer Antenne, einem Schwingkreis und einem Empfänger für das Synchronisationszeitsignal. Vorteilhafterweise ist der Empfänger für das Synchronisationszeitsignal und der Empfänger für das Funktelefon eine Einheit. Hierbei kann der Empfänger und die Auswertung für das Synchronisationszeit- signal in dem Basisbandempfänger-Chip des Funktelefons integriert werden. Dies hat den Vorteil, daß Empfänger- funktionen mehrfach sowohl für den Funkuhrempfänger als auch für den Empfänger für das Funktelefon genutzt werden können . Die Erfindung wird nachfolgend anhand der beigefügten Zeichnung näher erläutert. Es zeigt:The radio clock receiver consists of an antenna, an oscillating circuit and a receiver for the synchronization time signal. The receiver for the synchronization time signal and the receiver for the radio telephone are advantageously one unit. Here, the receiver and the evaluation for the synchronization time signal can be integrated in the baseband receiver chip of the radio telephone. This has the advantage that receiver functions can be used several times both for the radio clock receiver and for the receiver for the radio telephone. The invention is explained in more detail below with reference to the accompanying drawing. It shows:
