Definitions

  • the invention relates to a radio clock according to the preamble of claim 1.
  • Radio clocks are generally supplied with a time signal via the transmitter DCF-77 of the Physikalisch-Technische Bundesweg.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
