Definitions

  • the invention relates to a radio clock according to the preamble of claim 1.
  • Such a radio clock equipped with a power reserve in the form of its own clock circuit (and also called “autonomous” because of this internal timing), is described in the contribution by H. Effenberger "Microprocessor-controlled radio clock with analog display” in the volume of the report on the 4th Darmstadt Colloquium “FUNKUHREN” (1983), edited by Prof. W.Hilberg, pp. 104-109. It is a pointer watch with devices for detecting the position of the hands and for automatically correcting the hands from any momentary false indication. When starting up such a watch (eg after replacing its battery), the hands, driven by stepper motors from the internal clock circuit, are first rotated to a reference position in rapid traverse.
  • That decoded point in time is a numerical value which is transferred to a comparator of a microprocessor as a setpoint for the angular position.
  • This causes the pointers to come out of the internal Clock circuit driven and rotated to the angular positions that correspond to the display of that numerically predetermined time.
  • the hands move again in rapid traverse, from which even the layperson realizes that during this directional run from the previous reference position it is not yet a time display, but only the (rotary) movement there.
  • the pointers are then moved (again by the internal clock circuit) so that the viewer now has the normal display of a pointer clock in front of them.
  • the receiver After a certain operating time of the clock, the receiver is temporarily switched on again to receive new absolute time information, and the processor compares the numerical value decoded therefrom with the current pointer angle position; which, however, has no effect if the time is correct for the pointer movement (and thus for the viewer). Only in the event of a difference (i.e. in the case of a currently incorrect time display) is this quickly corrected using the internal clock circuit. After that, the clock runs autonomously again when the receiver is switched off, meaning that it continues clocked correctly.
  • the decoded numerical value is recognized as valid, it is read directly from a digital clock for digital time display, while for a clock that displays electromechanically (for example by means of pointers), it is the target position in the above-mentioned angular position comparator for checking and correcting the pointer position is handed over.
  • This passed time information is therefore a mere numerical value.
  • the second grid of the coding on the transmission side is therefore no longer contained in it. If necessary, continuous seconds information must be generated separately by the receiver, synchronized with the current minute mark and enumerated.
  • the stepper motor controls for corrective (rapid traverse) or time-keeping (normal gear) pointer movement can therefore not be carried out from the decoded time information, but the generic clock is equipped with the autonomous internal clock circuit.
  • the radio clock is set up so unfavorably that there is no sufficient reception for a correction of the current time display possible - display
  • the receiving antenna built into the radio clock must be oriented or positioned differently in order to be able to decode the current time and correct the display on it.
  • such a digital quality code display in a consumer radio watch with a pointer time display is also unreasonable per se, because it disturbs a balanced dial design even more than the aforementioned light-emitting diodes; and for the layperson this reception indicator number display is also without the desirable meaningfulness, rather deterrent.
  • radio clock with pointer time display is the radio clock with digital display according to the building instructions of R. Goessler "micro computer controlled radio clock in mini format" in FUNKSCHAU 1979 booklet 14 (S.839-842), 15 (S.891- 895), 16 (p.959-962) 17 (p.1027-1029 and 18 (p.1081-1083).
  • a light-emitting diode is connected to the comparator output in the interior of the kit as a reception adjustment aid or for troubleshooting.
  • a comparable to the second blinker, but acoustic presentation is known in a digitally displaying radio clock according to GB-A-2 019 054, where (in addition to visual error display) an acoustic signal generator (which is also used as an alarm signal generator when an alarm signal is reached) from the time decoder predetermined wake-up time) can be activated briefly, for example, at the beginning of each second.
  • an acoustic signal generator which is also used as an alarm signal generator when an alarm signal is reached
  • this acoustic impulse radiation can be switched off (and thus of course ineffective)!
  • a radio-controlled clock of the generic type or even of the generic type is no longer at all if no complete, i.e. coded, current time information is transmitted via radio and evaluated in the autonomously timed clock for occasional control and, if necessary, for adjusting the angle of the pointer will; but if, according to the old technology of the clock networks, only advance pulses for the advancement of a non-autonomous time display are transmitted, as described, for example, by G. Krug "radio remote controlled clocks" in "clocks and jewelry” Vol.9 / No.2 (1971) p. 57-59. Such an advance remote control is at most relatively fail-safe insofar as no absolute time information has to be decoded in the clock.
  • this nominal time synchronization is only relatively immune to interference insofar as only the occurrence of the synchronization time mark is demodulated, but it is not necessary to decode absolute time information.
  • the catch range specified in the clock in terms of circuitry is too far from the actual time, then the broadcast synchronization mark can no longer be received and the time display will continue to run incorrectly in the future.
  • a possible indicator about the quality of the radio signal to be received would also be irrelevant here, since even in good reception conditions, the missed signal is of no use.
  • a correction of a limited deviation in the minute display can take place, but not a correction of the hour display.
  • the clock will therefore continue to run incorrectly if, for example, the correct minute but an incorrect hour is displayed at the start of operations or after every change from summer time to winter time.
  • the last cited document provides for the special effort of an additional, computer-controlled date clock, which stops the hands of the clock for one hour or lets it advance by one hour in rapid traverse to the time change even in the case of different calendar data to be preprogrammed each year Understand the display - which is completely independent of the reception of the radio time signal as well as the correctness of the current display before or after such functional intervention. Therefore, the problem underlying the invention does not arise here either.
  • the multivibrator continues to run at its natural frequency, which results in a beat mode with briefly alternating lead and lag periods of the factory.
  • the time display is therefore not touched, and it always stays on time even on average regardless of the actual reception conditions. In any case, the consumer does not notice the lack of clock reception when looking at the dial.
  • the time display is incorrect (like when the watch was started with an arbitrary current hand position), then this cannot be corrected by undisturbed reception of the seconds markers, since yes (contrary to the principle with the generic clock) no absolute time information received and no pointer position detection is operated.
  • the current reception quality is again completely irrelevant for the consumer even with this prior art, which is why no indication of the problem solved according to the invention can be derived from this either.
  • the display control takes place in the manner of clock networks via cable from a mother clock, but with the special features that the mother clock itself can be radio-controlled by a reference clock and that only incremental pulses are now transmitted in the conventional way, rather than coded absolute time information.
  • These are converted into digital pointer display setpoint angle information so that a drive operating in start-stop mode (i.e. not as a quasi-continuous stepper motor) is switched on until its output shaft has reached the angular position corresponding to the setpoint display specification.
  • start-stop mode i.e. not as a quasi-continuous stepper motor
  • the generic radio clock (according to Effenberger) is only equipped with an hour and a minute hand, which are moved independently of each other from the internal clock circuit via their own pulse-driven clock stepper motor. This allows the circuitry outlay for the detection of the respective pointer movement through its reference position (for the pointer position feedback that is used in one electronic counter) to be kept relatively low and, for each pointer separately (i.e. without excessive rotational speed stress on the pointer mechanism), the computer-controlled display corrections (e.g. from the initial position at the start of operation) to the currently decoded absolute time by means of temporarily faster clocking from the internal clock circuit in rapid traverse perform.
  • the invention has for its object to design a generic radio clock in such a way that a simple indicator of the reception quality of the pulse train to be decoded with a comparatively little additional technical expenditure for the pointer time display that is already present, functionally and organically in a consumer radio clock can be included in such a way that it can easily be conveyed to the layperson whether regular radio reception is currently being given at the start of operation (which will soon lead to the setting of the pointer display, which is typical for a generic radio clock, to the current point in time from any malposition); or whether reception is too disturbed when the radio clock is currently set up for decoding radio information suitable for display correction.
  • the object is achieved in that the generic radio clock is equipped with a reception indication according to the characterizing part of claim 1.
  • an indicator pointer referred to here as the present, is at least temporarily directly from the not yet decoded by means of its pulse stepping motor (not for the correction movement or for timely display from the internal clock circuit, but instead) Pulse sequence of the received time telegram switched on.
  • the indicator pointer introduced according to the invention (at the start of operation without displaying current time information or even performing a display correction run) becomes undisturbed in reception conditions rhythmically familiar second step sequence moves.
  • This undisturbed pointer advance therefore only serves to make the regular reception of discrete (usable for decoding) pulses clear.
  • this additional (indicator) pointer movement can also be easily interpreted by the layperson, if necessary, to the effect that the radio clock is now working normally. So he recognizes that their time display, in the case a display that differs from the actual time, will set the correct time display at the next comparison time.
  • Switching the control of the pointer stepper motor in question from the demodulated receive pulses to the time-keeping device can be advantageous - especially if it is a matter of realizing the decoding of the time information and determining and tracking the displayed time by means of a microprocessor - in a circuit-technical connection with the decryption circuit and the comparator for the time information transmitted via radio coding.
  • a radio receiver 1 with a radio frequency part 3 connected to an antenna 2 (for example a ferrite coil), this demodulator 4 and output amplifier 5 connected downstream supplies a square-wave pulse train 6 with a pulse repetition frequency of 1 Hz, which is encoded within one by means of binary pulse length coding Minute contains complete time and date information (not considered in the drawing).
  • the information about the current point in time can be detected therefrom by means of a decryption circuit 7 and with the current time display, in the form of the position of hands 8 in front of the minute track on the dial 9 of a clock, in a comparator 10 can be compared, which is supplied by a pointer position detector 11 (on the basis of, for example, rotary angle meters or incremental actuators).
  • a pointer here the second hand 18
  • this pulse sequence 6 is disturbed (in the form of failing or interrupted individual pulses), then the movement of the pointer used for the reception indication (here the second hand 18) can be seen without further ado because it is not the familiar, uniform one Executes step movement in the angular second cycle, but eg jumps uneasily.
  • a switchover device 19 is provided for the control of the stepping motor 16, via which - as just described - the pulse train 6 is passed from the radio receiver 1 to the reversing circuit 14 as soon as the overall arrangement, or at least the radio receiver 1 after a break in operation is put into operation; for example by means of an operating switch 20, or for example as a result of the use of a power source 21 (for example a battery).
  • a set input 23 for the switching device 19 possibly via a trigger circuit 22 for triggering a set pulse driven for this switching of the pulse train 6 on the reversing circuit 14.
  • the progression of the indicator pointer 18 therefore only actually indicates the passage of time in a second pattern when an undisturbed pulse sequence 6 is received.
  • the switchover device 19 is switched via its reset input 24 to receive the time-keeping pulses 25 from a time-keeping device 26, that is to say to a clock-second cycle; in which from now on (until the next break in operation of the radio clock), for example, a second hand 18 is switched on.
  • the time-keeping pulses can also temporarily have a higher frequency, for example, if the comparator 10 detects a deviation between the time indicated by the pointer 8 and the current time decoded by the decoding circuit 7.
  • the block diagram shown does not take into account the fact that it may be more expedient to provide separately controlled stepping motors 16 on the one hand for the second hand 18 and on the other hand for the hour and minute hands 8 and to control them separately from the comparator 10; in order to enable a quick adjustment of the position of the hands 8 without having to rotate the second hand 18 unduly quickly via a gear coupling.
  • Such separate motors 16 also make it possible to select the minute or even the hour hand 8 as the reception indicator pointer; in this case, the function of the switching device 19 would include separating the indicator motor 16 from the received pulse train 6 and applying the time-keeping pulse train 25 to the clock drive circuit.
