Definitions

  • the invention relates to a radio clock according to the preamble of claim 1.
  • Such an autonomous radio clock is known from US Pat. No. 4,650,344 - and in particular with regard to the pointer position query for comparing the display with the current time information received via radio from US Pat. No. 4,645,357.
  • the energy supply from a dry battery
  • mains switch is connected via a mains switch.
  • the object of the invention is to enable the radio clock to be interrupted for the reasons mentioned or motivated for other reasons, without thereby causing longer start-up intervals or malfunctions.
  • the inhibitor circuit can be used to temporarily electrically block the electrical control of the step-up device for the time display, thereby causing a divergence between the actual time and the displayed time. As soon as this blockage is removed, the mode of operation of the time adjustment processor leads again to the correction of the time display.
  • the radio-controlled clock 11 outlined in the block diagram contains in its factory housing 12 a receiver demodulator 14, which is supplied with radio-frequency energy via an antenna 13, in order to obtain coded current time information 15.
  • An autonomous, preferably quartz-stabilized, time-keeping circuit 16 supplies the incremental pulses 17 for a time display device 18 which preferably as a pointer display with hour hand 19 and minute hand 20 (and possibly second hand, not included in the drawing) in front of a minute track 21 and operated via a step-up device 22 - preferably in the form of a stepping motor with gear reduction of the pointer movement.
  • a display interrogator 23 (for example an angle decoder for determining the current position of the pointers 19, 20 or an end position encoder for providing information about the passage of the pointer through a predetermined position) provides current display information 24.
  • decoder converters 25, 26 the information 15, 24 is shown such that it can be evaluated in relation to one another in a time comparison comparator 27; to provide correction pulses 28 to the advancing device 22 in the event of a momentary false display (compared to the actual, current time information 15) until the actual time display again matches the current time information 15.
  • the converters 25, 26 and the comparator 27 are implemented in a time alignment processor 29, which in practice can also perform decoding tasks of the interrogation device 23 (which is not taken into account in the drawing for a better overview).
  • the functional parts of the radio clock 11 are fed from an energy supply 30, for example a secondary battery or the memory of a primary energy generator (solar cell, thermal cell or the like).
  • an energy supply 30 for example a secondary battery or the memory of a primary energy generator (solar cell, thermal cell or the like).
  • an interruption connection 31.1 is provided, via which the reset input 33 of the processor 29 can be controlled, for example by means of a manually operated pushbutton switch 32.
  • This places the processor 29 in its initial function position, which corresponds to the start-up of the radio clock 11 and in which, consequently, it cannot be assumed that the random momentary position of the hands 19, 20 of the correct time display in relation to the time information which can actually be received by radio 15 corresponds to. Therefore, the processor 29 first controls the entry of the hands 19, 20 into a defined starting position, preferably the zero o'clock position 34 (which is indicated in the drawing on the minute track 21 by a double mark). While moving into this position or when this position 34 is reached, the desired display position is determined in the comparator 27 in accordance with the actual, current time information 15 and the time display is then set up accordingly by supplying the indexing device 22 with the correction pulses 28.
  • the display interrogation device 23 does not detect the position of the pointers 19, 20 directly, but only indirectly, namely via certain wheel positions in the gear connection to the indexing device 22, then care must be taken when mounting the pointer that the current pointer setting position with the assigned gear position corresponds. In watchmaking, it is common to set the hands in the zero or start position 34.
  • this is the position into which the transmission is turned by the indexing device 22 as the starting position for the function of the time adjustment processor 29.
  • the gear train 35 is first moved into the position which corresponds to the time display starting position 34;
  • the display interrogation device 23 coupled to the gear train 35 signals that this initial position 34 has been reached, the drive of the gear train 35 is stopped briefly in order to then be moved into the display position corresponding to the actual instantaneous time information 15 by means of the correction pulses 28.
  • this brief stopping of the gear train 35 in the defined initial position 34 is not sufficient for the assembly time required for manual or semi-automatic setting of the hands 19, 20.
  • a (further) interruption connection 31.2 is provided on the movement housing 12. This is preferably mounted so that it can be reached from a contact rail 36 when the movement housing 12 is moved over the assembly line in the course of its assembly.
  • the gear train 35 is first activated via the processor 29 (as described above) drove his initial position 34. So that there is now time to set the pointer, ie the gear train 35 is not immediately rotated further in the position corresponding to the current time information 15, the movement housing 12 is now moved onto the contact rail 36.
  • an inhibit input 37 is activated in the course of the activation of the switching device 22 (shown in the drawing to simplify the overview, but also in the processor 29 feasible) controlled in order to leave the gear train 35 initially in the initial position 34 that has just been reached and to be able to mount the pointers 19, 20 to this initial position 34 (zero o'clock).
  • the movement housing 12 is pushed or lifted off the contact rail 36 again, so that the control blockage via the inhibit input 37 is removed again, and the gear train 35 with the pointers 19, 20 is corrected by means of the correction pulses 28 into that of the actual ones Time information 15 corresponding angular position turned.
  • the interruption connection 31.2 can also be controlled by means of an additional switch mounted on the work housing 12, or by means of a line bridge that can be produced and then removed again during assembly (not taken into account in the drawing).
  • the inhibit input 37 can also be provided to be controlled via a memory circuit 38 (which, contrary to the simplified circuit diagram representation, can preferably also be implemented within the processor 29).
  • This memory circuit 38 is (only) prepared when the power supply 30 is switched on and set via the display information 24 when the gear train 35 has then reached the initial position 34 for the first time.
  • the indexing device 22 is now electrically blocked and an arbitrarily long period of time is available for setting the pointer.
  • the movement housing 12 is moved further, for example, via the contact rail 36 and the function of the memory circuit 38 is finally interrupted by actuation of the interruption connection 31.2 until the next time the power supply 30 fails and reappears; so that in the normal Operation of the radio clock 11, reaching the initial position 34 or a random activation of the interruption connection 31.2 without influencing the inhibit input 37 for the function of the switching device 22.
