Abstract
Description
Die Erfindung betrifft eine Funkuhr nach dem Oberbegriff des Anspruchs 1.The invention relates to a radio clock according to the preamble of claim 1.
Funkuhren werden im allgemeinen über den Sender DCF-77 der Physikalisch-technischen Bundesanstalt mit einem Zeitzeichensignal versorgt. Eine erste Art von Funkuhren empfängt das Zeitzeichensignal ständig und bringt stets die empfangene Zeit zur Anzeige. Eine zweite Art von Funkuhren synchronisiert eine autonom laufende, quarzgesteuerte Uhr periodisch mit dem Zeitzeichensignal. Insbesondere kleine, batteriebetriebene Funkuhren arbeiten aus Energiespargründen nach dem zweiten Prinzip. Das Synchronisieren des internen Uhrenwerks mit dem Zeitzeichensignal findet typischerweise alle 24 Stunden in den frühen Morgenstunden statt und ist unabhängig von weiteren Faktoren wie z. B. der Empfangsqualität des Zeitzeichensignals oder der Stärke von in der Umgebung vorherrschenden Störfeldern.Radio clocks are generally supplied with a time signal via the transmitter DCF-77 of the Physikalisch-Technische Bundesanstalt. A first type of radio clocks constantly receives the time signal and always displays the time received. A second type of radio controlled clock periodically synchronizes an autonomously running, quartz-controlled clock with the time signal. Small, battery-operated radio-controlled clocks in particular work according to the second principle to save energy. The synchronization of the internal clockwork with the time signal typically takes place every 24 hours in the early morning and is independent of other factors such as e.g. B. the reception quality of the time signal or the strength of prevailing interference fields in the environment.
Es ist weiterhin bekannt, daß viele elektronische Geräte aus dem Gebiet der Signalerzeugung oder Signalverarbeitung Störfelder erzeugen, die andere Funktionen im gleichen Gerät oder Funktionen von in der näheren Umgebung aufgestellter Geräte stören oder unmöglich machen können. Diese Art von Störfeldern unterbinden den Betrieb von Funkuhren in Geräten, wie z. B. PCs, Fernsehern, Videorecordern usw. Bei dem Betrieb derartiger Geräte ist der Empfang des Zeitzeichensignals nur mit sehr großem technischen Aufwand möglich.It is also known that many electronic devices in the field of signal generation or signal processing generate interference fields which can interfere with or make impossible other functions in the same device or functions of devices placed in the vicinity. These types of interference fields prevent operation of radio clocks in devices such as B. PCs, televisions, video recorders, etc. In the operation of such devices, the reception of the time signal is only possible with very great technical effort.
Eine erste Aufgabe der Erfindung ist es, ein Verfahren zum Betreiben einer Funkuhr anzugeben, das den Betrieb der Funkuhr in einer störfeldbehafteten Umgebung gestattet. Diese Aufgabe wird gelöst durch ein Verfahren mit den kennzeichnenden Merkmalen des Anspruchs 1.A first object of the invention is to specify a method for operating a radio clock which allows the radio clock to be operated in an environment subject to interference. This object is achieved by a method having the characterizing features of claim 1.
Es ist eine weitere Aufgabe der Erfindung, eine Funkuhr anzugeben, die für den Betrieb in einer störfeldbehafteten Umgebung geeignet ist. Diese Aufgabe wird durch eine Funkuhr mit den kennzeichnenden Merkmalen des Anspruchs 7 gelöst.It is a further object of the invention to provide a radio clock which is suitable for operation in an environment subject to interference. This object is achieved by a radio clock with the characterizing features of claim 7.
Die vorteilhafte Ausgestaltung der Erfindung erfolgt gemäß den Merkmalen der abhängigen Ansprüche.The advantageous embodiment of the invention takes place according to the features of the dependent claims.
Im folgenden sei ein Ausführungsbeispiel der Erfindung anhand der Figuren erläutert. Dabei zeigen die
- Figur 1
- ein Blockschaltbild der erfindungsgemäßen Funkuhr,
- Figur 2
- eine Ausführungsform der Erfindung.
- Figure 1
- 2 shows a block diagram of the radio clock according to the invention,
- Figure 2
- an embodiment of the invention.
Die in der Figur 1 dargestellte Anordnung besteht aus einer Funkuhr FU mit einer quarzgesteuerten Uhr QU, die durch einen Zeitzeichenempfänger ZE über einen Signalprozessor SP mit dem empfangenen Zeitzeichensignal synchronisiert wird. Der Zeitzeichenempfänger ZE weist eine zum Empfang des Zeitzeichensignals geeignete Antenne auf. Die Funkuhr FU bildet zusammen mit einer weiteren Einrichtung G1 eine Funktionseinheit, wobei die weitere Einrichtung G1 Betriebszustände einnehmen kann, die ein derartiges Störfeld erzeugen, die den Empfang des Zeitzeichensignals stören bzw. unmöglich machen. Erfindungsgemäß ist ein Detektor DS vorgesehen, der einen solchen Betriebszustand der weiteren Einrichtung G1 erkennt und bei Vorliegen eines solchen Betriebszustands die Synchronisierung der quarzgesteuerten Uhr QU mit dem Zeitzeichensignal unterbindet.The arrangement shown in Figure 1 consists of a radio clock FU with a quartz-controlled clock QU, which is synchronized by a time signal receiver ZE via a signal processor SP with the received time signal. The time signal receiver ZE has an antenna suitable for receiving the time signal. The radio clock FU forms together with one a further device G1 a functional unit, the further device G1 being able to assume operating states which generate such an interference field, which disrupt the reception of the time signal or make it impossible. According to the invention, a detector DS is provided which detects such an operating state of the further device G1 and, if such an operating state is present, prevents the synchronization of the quartz-controlled clock QU with the time signal.
In einer vorteilhaften Ausgestaltung der Erfindung ist der Detektor DS mit dem Zeitzeichenempfänger ZE verbunden und unterdrückt den Empfang des Zeitzeichens, wenn die weitere Einrichtung G1 starke Störfelder erzeugt. Die weitere Einrichtung G1 kann z. B. ein Computer, ein Taschenrechner, ein PC, ein Großrechner, ein Kraftfahrzeug oder ein Fernsehempfänger sein. Allen gemeinsam ist, daß sie beim Betrieb ein Störsignal erzeugen, das den gleichzeitigen funkgesteuerten Betrieb der Funkuhr nicht zuläßt. Andererseits erzeugen sie im abgeschalteten Zustand kein Störsignal.In an advantageous embodiment of the invention, the detector DS is connected to the time signal receiver ZE and suppresses the reception of the time signal when the further device G1 generates strong interference fields. The further device G1 can, for. B. a computer, a calculator, a PC, a mainframe, a motor vehicle or a television receiver. What they all have in common is that they generate an interference signal during operation that does not permit the radio-controlled operation of the radio clock at the same time. On the other hand, they do not generate an interference signal when switched off.
In einer weiteren Ausgestaltung der Erfindung überwacht der Detektor DS die Zuführung der Betriebsspannung UB an die weitere Einrichtung G1. Die Synchronisation findet ausschließlich dann statt, wenn der weiteren Einrichtung keine Betriebsspannung zugeführt wird und diese sich somit im ausgeschalteten Zustand befindet. Der Detektor besteht in diesem Fall aus einem Umschalter, der dem Zeitzeichenempfänger ZE im Wechsel zur weiteren Einrichtung G1 die Betriebsspannung zuführt. Durch diese Maßnahme ist gewährleistet, daß der Zeitzeichenempfänger ZE nur dann in Betrieb genommen werden kann, wenn der weiteren Einrichtung G1 keine Betriebsspannung zugeführt wird und diese abgeschaltet ist.In a further embodiment of the invention, the detector DS monitors the supply of the operating voltage UB to the further device G1. The synchronization takes place only when no operating voltage is supplied to the further device and the latter is thus in the switched-off state. In this case, the detector consists of a changeover switch which, in alternation with the further device G1, supplies the time signal receiver ZE with the operating voltage. This measure ensures that the time signal receiver ZE can only be put into operation when no operating voltage is supplied to the further device G1 and the latter is switched off.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung besteht der Detektor aus einem breitbandigen Funkempfänger, der die von der weiteren Einrichtung G1 erzeugte Störstrahlung erfaßt und ab einer gewissen Stärke der Störstrahlung die Synchronisation der quarzgesteuerten Uhr QU durch den Zeitzeichenempfänger ZE unterbindet.In a further advantageous embodiment of the invention, the detector consists of a broadband radio receiver which detects the interference radiation generated by the further device G1 and, from a certain intensity of the interference radiation, prevents the synchronization of the quartz-controlled clock QU by the time signal receiver ZE.
In beiden o. a. Ausführungen der Erfindung kann vorgesehen sein, daß die nächste Synchronisation der quarzgesteuerten Uhr QU nach Ablauf einer festgelegten Zeitspanne seit der letzten erfolgreichen Synchronisation erfolgt. Damit kann erreicht werden, daß die Synchronisierung z. B. alle 24 Stunden erfolgt. Bei einem periodischen Betrieb der weiteren Einrichtung G1 erfolgt dann auch die Synchronisierung der quarzgesteuerten Uhr QU mit dem Zeitzeichensignal regelmäßig.In both of the above Embodiments of the invention can provide that the next synchronization of the quartz-controlled clock QU takes place after a predetermined period of time has elapsed since the last successful synchronization. This can be achieved that the synchronization z. B. takes place every 24 hours. In the case of periodic operation of the further device G1, the quartz-controlled clock QU is then also synchronized regularly with the time signal.
