Definitions

the invention relates to an appointment radio clock according to the preamble of claim 1.
Such a clock is known from DE-OS 35 10 636. With it, the time at which an alarm signal is to be issued can be entered digitally (for a comparison of the binary pattern of the signal time with that of the currently given time), as it is as such from DE-OS 22 06 592 for a digital bracelet -Alarm clock is previously known.
that generic prior publication also discloses the possibility of querying the coincidence of the position of the hour hand and the position of the alarm hand by means of a conventional pointer movement scanning device and of issuing a switch-on signal for the alarm signal via an electromechanical switching path.
An electromechanical or electronic scanner works somewhat more precisely than the cam-engaging mechanism for the binary pattern of a multi-bit angle encoder, which is formed on a pointer wheel or a carrier wheel coupled to it in a geared manner, as described in more detail in DE-PS 26 09 871 (FIG. 6). But even with such scanning devices, the response accuracy fluctuates.
the invention is therefore based on the object of designing an appointment radio clock of the generic type in such a way that, despite the use of such a conventional scanning device, the highly precise triggering of the alarm signal which is typical and to be expected for a radio clock takes place.
the wake-up time occurs, stationary switch-on behavior is ensured, so that the coincidence condition can now be switched through precisely (without play) from the register-derived release signal for alarm output.
a radio-controlled alarm signal triggering to the exact second can be achieved at any point in time that can be selected in the setting grid (for example, every ten minutes).
appointment radio clock 1 also has in particular a radio receiver 2 with a demodulator 3, which is supplied with radio frequency energy via an antenna 4, which is modulated every minute with binary-coded current time information 5. This appears, provided there are sufficient radio reception conditions, Behind the modulator 3 as a pulse-modulated signal sequence 6 (with suppression of the respectively fifty-ninth second).
the current time information 5 contained therein is compared in a control circuit 7 with display information 8 from the display device 9, given by the momentary position of pointers 10 in front of a dial 11. They are driven by an electromechanical converter 12.
an output stage 13 for operating the converter 12 is operated at high speed f2, for example from a time-keeping circuit 15, until the current display information 8 of a display detector 16 ( preferably realized as a light barrier query of the pointer mechanism), the correct position of the pointers 10 with respect to the current time information 5 is determined.
the control circuit 7 can now switch the output stage 13 to time-keeping operation from the oscillator circuit 15, and the pointers 10 are moved on with the frequency f1 at the correct time.
the registers in the control circuit 7, which are set by the time information signal sequence 6 and are now clocked further from the time-keeping circuit 15, have the effect that the radio receiver 2 does not remain in operation for any length of time, in particular in the case of a battery-operated appointment radio clock 1, but in circuit-technically predetermined time cycles for the pointer position control and possibly correction is switched on again, as illustrated by the control information 18 in FIG. 1.
the appointment radio clock 1 is also equipped with an electronic coincidence circuit 19, which can be implemented in the context of a processor, which in particular also performs the function of the control circuit 7.
a manually operable input device 20 allows the desired signaling time to be set, which is indicated, for example, by the position of an alarm time pointer 27 in front of the dial 11.
a scanner 21 (constructed, for example, as the classic alarm mechanism, as an angle code scanner or else as a sensor similar to the display detector 16) provides a switch-on signal 22 when the position of the pointer mechanism corresponds to the angular position of the alarm time pointer 27 set up for the time of the alarm.
the signal transmitter 23 is not yet triggered by an alarm signal 24 as a result of this alone.
the function of the scanning device 21 includes a certain switching cycle 30 of typically plus / minus two minutes around a predetermined signaling time 31.
certain signaling times 31 ′ are functionally permitted, for example on the basis of a correspondingly designed latching coupling 32 in the operative connection of the manual input device 20.
These are expediently offset from one another by a periodic setting grid 33 which is larger than the sampling switching cycle 30 and, in the given example, is expediently ten minutes in relation to the full hour.
this setting raster 33 is greater than the period of one revolution of the alarm time pointer 27 minus the switching cycle 30, then it is ensured that within the period of the switching cycle 30 there can possibly be a single signaling time 31 ', as can be seen in FIG 2 results without further ado.
the alarm time pointer 27 is adjusted with respect to the scanning device 21 in such a way that it is adjusted in front of the dial 11 in such a way that the scanned signaling time 31, including the response switching cycle 30 that is halfway between the two (short) before the nominal signaling point in time 31 ', shortly before reaching this point in time 31' only the switch-on signal 22 initially appears.
an interval and pulse generator 34 fed from the register of the control circuit 7 supplies a signal and Time 31 'beginning Release signal 35 to the coincidence circuit 19. This therefore switches through and outputs the alarm signal 24, as long as both the switch-on signal 22 from the pointer scanning device 21 and the release signal 35 are still present.
the switch-on signal delivered via it is typically present for between thirty and forty-five minutes until the scanning contact paths open again in the course of the further rotation of the pointer mechanism, which is queried in terms of operation.
the duration of the alarm signal 24 is expediently limited (in particular in order to avoid a permanent load on the electrical power source of a wireless appointment clock 1) by means of the duration of the enable signal 35, in which, when it disappears, the coincidence condition of the circuit 19 again goes out.
the interval and pulse generator 34 is therefore not only designed to switch through in the fixed rhythm of the adjustment grid 33 also implemented on the clutch 32; in addition, it contains a monostable characteristic based, for example, on a counting basis, in order to limit the output of signal 35 in time.
a flip-flop 36 can also be provided in front of or behind the coincidence circuit 19, which cancels this coincidence condition a circuit-specific time period after the coincidence-related alarm signal 24 is inserted, or blocks the forwarding of the output alarm signal 24.
this bistable flip-flop 36 has a set input 37 that is dynamically responsive to the onset of the control information, then the flip-flop 36 reset with a time delay from the alarm signal 24 can only be set again in preparation for the coincidence condition when the switch-on signal triggered by the pointer scanning device 21 is activated 22 after the corresponding continuation of the pointer 10 has ended and then reappears when an alarm time setting is reached again.
electromechanical signaling sampling device 21 nevertheless a radio-controlled output of a time-limited alarm signal 24 can be effected to the exact second.
