Definitions

  • the invention relates to an autonomous radio clock according to the preamble of claim 1.
  • Such a radio clock is known from the article by W. Ganter "JUNGHANS radio clock RC 2" in Goldschmiede-Zeitung issue 1/1988 page 148.
  • This radio clock which has quickly become the market leader, switches the receiver periodically to predetermined ones Points of time, temporarily on, in order to correct the current time display if necessary based on time telegrams currently received via radio. Regardless of this, the receiver is switched on each time a reset or START switch is pressed, which simultaneously moves the current time display to a 00:00:00 reference position. As soon as radio reception provides valid time information, the receiver is switched off again and the time display is moved to the corresponding position in rapid traverse. If mechanical parts (pointers or numerical drop-down flaps) have to be moved for this purpose, the time required for this is taken into account in the control, so that the actual, current time is finally displayed.
  • the time information transmitted by the radio transmitter is related to a specific geographical time zone.
  • the display on the carried watch is no longer correct with regard to the hour display when the traveler exceeds a time zone limit because the hour display then lags or advances by one hour (or, depending on the time zone circumstances, by half an hour) based on the newly reached time zone.
  • the invention has for its object to equip a radio clock of the generic type such that it can be used with correct time display even after a time zone change without receiving time telegrams stored in the new time zone; in particular, the possibility should also be opened of being able to put a radio-controlled clock of the generic type into operation even in any case as a clock of customary accuracy if no usable time telegrams can currently be received via radio.
  • the solution according to the invention is based on the knowledge that it suffices to manually correct (advance or reset) the previous hour display in the correctly displaying radio clock after the time zone change, whereupon this time zone correction will also automatically take place in the radio-controlled time display in the future is taken into account.
  • the time zone correction value can be entered manually into a separate hourly memory, from which this correction value (taking into account its addition or subtraction sign) with the decoded hourly information currently received by radio from a transmitter that is set to a different time zone is contracted to display the actual local time. This means that the watch can also operate wirelessly outside the time zone to which the transmitter is set.
  • the traveler If the traveler returns to the area of the time zone that corresponds to the transmitter, then he can either undo the zone correction previously carried out by manually resetting the additional zone hour memory to zero, so that from now on the hourly information received by radio no more zone correction is added; or the radio clock is restarted by confirming the reset button, which simultaneously resets the hour correction memory to zero.
  • the solution according to the invention also makes it possible, in order to start up the clock without instantaneous reception of valid time telegrams in a conventional manner, to wait for the synchronization signal, for example broadcast by radio stations at certain full hours, and then to actuate the reset or START switch.
  • This resets the time display to 00 minutes and 00 seconds and starts the watch under its internal time base for time display advancement - however with an arbitrarily incorrect (randomly given) hour display or with the hour 00 if the hour display is also reset was set to 00.
  • the hour display is corrected together with the update of the remaining current time display, if it is still a valid radio time telegram should be able to be received and decoded.
  • the display change can be implemented practically without inertia, if it is a non-mechanical time display, that is such as an electronic display for the display of indexable pointer or number symbols; that the solution according to the invention can also be implemented in the case of time displays which are to be mechanically switched on (that is to say in the case of gears driven by gears or other mechanical displays such as numerals falling sheets), in which case the time delay for entering the 00 from the currently given display position is known only in such a manner - Correct reference position must be taken into account if the START switch was actuated when the hour synchronization mark appeared. The display is then switched on from the internal time base as soon as the current display has reached the actual, current time.
  • the autonomous radio clock 11 outlined as a block diagram has a receiver 13 connected to an antenna 12 and tuned to a time transmitter frequency with a decoder 14 for the current time information 15 contained in the demodulated reception information.
  • This decoded time information 15 is implemented in a register 16 for the segment control of a display 17 with hours (H), minutes (M) and seconds (S) display as the time information to be displayed 15 '.
  • the receiver 13 with decoder 14 in particular are not in constant operation. Rather, operation is only started when a reset or START switch 18 is actuated by means of switch-on information 20; OR if the time decoder 14 has detected a predetermined point in time (approximately reaching a full hour) (illustrated in the drawing by an additional interrogation of the minute register 16M), but now only for a period of time determined by a timer 19.
  • the START switch 18 also acts on a register reset in order to then continue to clock the display register 16 from an internal time-keeping circuit 22.
  • the output of the time information 15 obtained, for example, from the comparison of two successive time telegrams, via a changeover information 21 (shown here only in a functionally simplified manner) and a flip-flop 30, means that the receiver 13 and possibly the decoder 14 are switched off again and the time information 15 corrected in accordance with the time telegram is counted on from the internal clock circuit 22.
  • This clock circuit 22 is expediently a quartz-stabilized oscillator which can have been synchronized from the receiver 13 via a second clock line 23 to the modulation clock of the time telegrams transmitted by radio.
  • the jump in hours to be carried out when changing from summer time to winter time is taken into account on the modulation side in the time telegram transmitted by radio and therefore leads to the next time-controlled generation of the switch-on information 20 being taken into account in the activation of register 16 and thus to correcting the hour display H.
  • this radio clock 11 is used, for example is carried on long-distance trips where a time zone limit is exceeded, then the hour correction information required for this cannot be contained in the received time telegram from the time transmitter set to the previous time zone - regardless of whether this transmitter from the distance of the next time zone at all can still be received.
  • the fact of a time zone change is communicated to flight passengers, for example.
  • the hour display H belonging to the previous time zone can now be corrected via a manually operated hour switch 24, with the minutes and seconds displays M, S being continuously activated.
  • This provides, for example by repeated actuation of a key or rotation of a rotary switch, a sequence of hour correction pulses 25 or the immediate entry of a numerical value H into an hour memory 26 provided in addition to the hour register 16 H, which - like register 16 before - due to actuation of the START switch 18 had been reset to the initial position zero via its reset input.
  • the current register hour information 15'H is summarized in a summer 27 with the correction information ⁇ H in the hour memory 26 to take into account the positive or negative deviation of the current time zone hour from the transmitter related register hour 15 'H in the hour display 17 H.
  • the current correction entry in the time zone hour memory 26 can be shown to provide quick information about how many (forward- or counting down and possibly half or full) hours the current time zone related hour display 17 H differs from the time zone hour 15 ′ H of the transmitter location.
  • all he needs to do is delete the correction memory 26 again (by resetting the hour hand 24 or pressing the START switch 18 again), so that in the future the hour display 17-H no time zone correction is taken into account additively or subtractively, so instead the transmitter-related register hour 15 ′ H appears again as the currently applicable hour display 17 H.
  • the radio clock 11 When staying in an area in which no time transmitter can be received or for which no time transmitter is operated at all, the radio clock 11 as an autonomously operated clock from its clock circuit 22 can be put into operation in a timely manner that exactly when a, for example, the public Broadcasting at certain full hours of the time signal (which therefore only represents a time synchronization mark, no encrypted complete time information), the START switch 18 is actuated.
  • the start information 29 triggered thereby sets the flip-flop 30 again in order to trigger the switch-on information 20 for a new reception attempt.
  • the register 16 for the time display 17 is set again to 00:00:00 and operated from this full-hour display by the clock circuit 22 in a time-keeping manner.
  • the hour display H is activated intermittently, for example, until the hour switch 24 has been actuated to enter the hour correction or until decodable time information 15 has been obtained again via the receiver 13.
  • the hour switch 24 is actuated - represented in the simplified circuit by a control line 31 on the flip-flop 30 and the timing element 19 - the receiver is always switched over to periodic operation (queried, for example, from the minute register 16 M) for a new start-up that the time display on the display 17 is corrected immediately when the wearer of the watch 11 returns to an area in which the time telegram transmitter associated with the reception frequency can be received again.
  • the clock 11 could only be started with reference to neutral hour reference information, at that time with correction of the hour display 17 H on the basis of information obtained otherwise about the current hour of the day.
  • the information in the separate hour memory 26, which is no longer required is then expediently deleted at the same time, so that an incorrect hour H is not displayed via the totalizer 27 when the user of the watch 11 resets via the Switch 24 forgets.
  • the reset input R of the memory 26 is controlled via an OR gate 32 if, as mentioned, a new start of reception is initiated via the switch 18, or if a receiver changeover information 21 appears. If the wearer of the watch is in an incorrect time zone, he can modify the display again via the hour memory 26 as described.
