Definitions

  • the invention relates to a movement according to the preamble of patent claim 1.
  • the spring via a gear train a time display and a generator supplying an AC voltage.
  • the generator feeds a voltage converter circuit
  • the voltage converter circuit feeds a capacitive component
  • the capacitive component feeds a reference electronic circuit having a stable oscillator and an electronic control circuit.
  • the electronic control circuit comprises a comparator logic circuit and an energy dissipation circuit connected to an output of the comparator logic circuit and controllable by the comparator logic circuit in its power consumption.
  • One input of the comparator logic shaft is connected to the electronic reference circuit and another input of the comparator logic circuit is connected to the generator via a comparator stage and an auto-coincidence circuit.
  • the comparator logic circuit is adapted to compare a clock signal from the electronic reference circuit with a clock signal from the generator, and controls the magnitude of the power consumption of the electronic control circuit over the amount of power consumption of the energy dissipation circuit, depending on the result of this comparison this way, via the control of the control circuit power consumption regulates the gear of the generator and thus the course of the time display.
  • the power consumption of the Energy dissipationsscnies in the known from CH-597 636 clockwork is controlled by the comparator logic circuit according to CH-597 636, however, only in two stages. Namely, the power consumption of the energy dissipation circuit according to CH-597 636 is either maximum or zero. This means that the generator can either be braked only with maximum strength or not at all. This results in considerable control oscillations in the gear regulation of the movement. On this catfish results in a relatively poor energetic efficiency of the movement.
  • the voltage converter circuit according to CH-597 636 is a rectifier.
  • Diodes are commonly used in the watch-making technique for rectification, for example, as disclosed in GB-A-2,158,274, EP-A-0,326,312, US-A-4,653,931, EP-A-0,467,667, EP-A-0,326,313, EP-A -0,309,164, EP-A-0,241,219 and EP-A-0,679,968.
  • Diodes are passive components. The use of diodes as a rectifier during the entire life of a clockwork affected due to the diode threshold voltage, the energetic efficiency of the movement. Fermer is referred to EP-A-0,695,978.
  • General technical background, which is not relevant in the present context, is given by JP-A-58-179379. Of relevance in the present context, however, is EP-B-0,157,789.
  • the required drive power consists of the mechanical drive power for the movement, the friction power and the electrical power of the generator.
  • the electric power output of the generator is determined by the power consumption of an energy-consuming electronic circuit connected to the generator. It should also be noted that the frictional loss of the generator is directly related to the voltage induced by the generator. As a rough estimate is that the mass of a rotor of the generator must be higher, the higher the induced voltage should be.
  • the invention has for its object to provide a clock, the spring via a gear train a time display and a generator supplying an AC voltage and can be operated in energetically particularly favorable manner.
  • control oscillations can be reduced and in this way energy losses associated with the control oscillations can be reduced.
  • the power consumption of the electronic control circuit in a predetermined size range is even substantially steplessly controlled. This is a comparison with the clockwork according to the CH-597 636 significant reduction in the control vibrations and related significant improvement in the energy efficiency of the movement given.
  • FIG. 1 an electronic part of a movement according to the invention is shown as a block diagram.
  • a generator 1 supplying an alternating voltage is connected via an unillustrated gear train to a spring, also not shown.
  • the spring drives the generator 1 and a time display, not shown.
  • the nominal frequency of the AC voltage of the generator 1 is advantageously 2 n Hz, where n is a non-zero natural number.
  • the mechanical part of the movement according to the invention is state of the art. Reference is made in this regard to CH-597 636.
  • the voltage source circuit 2 feeds a first capacitive component 10.
  • the first capacitive component 10 supplies an electronic reference circuit 3, 4, 5 with a stable oscillator 3, 4 and an electronic control circuit 6, 7, 8, 9
  • the stable oscillator 3, 4 has a quartz crystal 4 whose oscillation defines a reference frequency.
  • the voltage converter circuit 2, the electronic control circuit 6, 7, 8, 9 and the electronic reference circuit 3, 5 with the exception of the quartz crystal 4 and with the exception of all the capacitive components present in said circuits are constructed as an IC 11. In another embodiment, even the capacitive components are integrated into the IC 11.
  • the electronic control circuit 6, 7, 8, 9 has a comparator logic circuit 6, whose one input to the electronic reference circuit 3, 4, 5 and the other input via a zero crossing of the AC voltage detecting comparator stage 7 and an anti-coincidence circuit 8 with connected to the generator 1.
  • the anti-coincidence circuit 8 is essentially a latch which prevents simultaneous input of pulses on both inputs of the comparator logic circuit 6.
  • the electronic control circuit 6, 7, 8, 9 has a connected to an output of the comparator logic circuit 6 and controllable by the comparator logic circuit 6 in their power consumption Energydissipationsscrien 9.
  • the energy dissipation circuit 9 is made up of a large number of identical ohmic resistors.
  • the size of an ohmic resistor is small in comparison with the magnitude of the resistance that results when all the ohmic resistances in series are connected in series.
  • the comparator logic circuit 6 controls the power consumption of the energy dissipation circuit 9 by counting a number of changed in the current path connected ohmic resistors. In this way, the power consumption of the electronic control circuit 6, 7, 8, 9 in a predetermined by the number of resistors size range is controlled substantially continuously.
  • the energy dissipation circuit 9 is also possible to construct the energy dissipation circuit 9 as a controllable current source.
  • the comparator logic circuit 6 compares a coming from the electronic reference circuit 3, 4, 5 clock signal with a derived from the generator 1 clock signal. Depending on the result of this comparison, the comparator logic circuit 6 controls the amount of power consumption of the electronic control circuit 6, 7, 8, 9 over the amount of power consumption of the Energydissipationsscrien 9. In this way, via the control of the control circuit power consumption of the gear of the generator 1 and thus the course of the time display regulated.
  • the control is designed so that the gear of the time display is synchronized in the desired manner with the reference frequency supplied by the quartz crystal 4.
  • the comparator logic circuit 6 has a counter whose count corresponds to a gear difference between the generator 1 and the electronic reference circuit 3, 4, 5.
  • the power consumption of the Energydissipationsscnies 9 is controlled in dependence on the count of the counter. Depending on the state of the counter 9 more or less energy is dissipated in the Energydissipationsscnies and thus the generator 1 more or less charged. Each count is associated with a predetermined effective resistance combination in the Energydissipationsscnies 9.
  • the comparator logic circuit 6, depending on the count can switch on or off the active current path, the ohmic resistances present in the energy dissipation circuit 9 individually and in various combinations in the active current path. In this case, of course, the case is provided that is switched at one or more counter readings none of said ohmic resistors in the active current path.
  • the control is limited by the fact that on reaching a certain maximum level of the counter counting of generator pulses is interrupted. This is particularly necessary to ensure trouble-free starting of all electronic components of the movement in the event that the spring is first re-opened after a complete stop of the movement.
  • a similar effect is achieved if the comparator logic circuit 6 and the Energydissipationsschaftung 9 so coordinated that the power consumption of the Energydissipationsscaria 9 for a predetermined Zahlerstands Scheme (eg 0 to 16) is kept minimal and linear when exceeding the predetermined meter reading range changes proportionally to the meter reading.
  • control can be interrupted at a certain low level of the counter and a counting of pulses.
  • the movement also has a device, not shown, for displaying the power reserve as a function of the count.
  • the power reserve is displayed by means of an LCD.
  • the electronic reference circuit 3, 4, 5 has a frequency divider circuit 5 connected between the stable oscillator 3, 4 and the connection to the electronic control circuit 6, 7, 8, 9. This divides the supplied from the quartz crystal 4 reference frequency in a defined manner to allow easier synchronization of the time display.
  • the voltage converter circuit 2 fulfills both a rectifier function and a voltage tripler function.
  • a first diode 14 is connected in series with the generator 1 and with the first capacitive component 10.
  • a first switch 19 is connected in parallel with the first diode 14, but in series with the generator 1 and in series with the first capacitive component 10. The first switch 19 is actively controlled by a first comparator 21.
  • the voltage converter circuit further comprises a voltage tripler circuit 12, 13, 15, 16, 17, 18, 20, 23, the input side to the generator 1 and the load side to the first capacitive element 10 and to the parallel connection of the first diode 14 and the first switch 19th is coupled.
  • a load-side connection of the voltage tripler circuit 12, 13, 15, 16, 17, 18, 20, 23 opens together with the terminal of the first capacitive component 10 facing away from the first diode 14 into a ground node 22.
  • the first comparator 21 compares the electrical potential at the terminal of the first capacitive component 10, which is not at ground potential, with the electrical potential of the non-ground potential load-side terminal of the voltage tripler circuit 12, 13, 15, 16, 17, 18, 20, 23.
  • the first switch 19 is closed by the first comparator 21 only when the voltage of the first capacitive element 10 for operating the first comparator 21 is sufficient and the electric potential the ground-free load-side terminal of the voltage trip circuit 12, 13, 15, 16, 17, 18, 20, 23 is high enough for further charging of the first capacitive element 10.
  • the first switch 19 is a first field-effect transistor and connected so that in its locked state, a part of its structure acts as a first diode 14.
  • the spring, the gear train, the generator 1, the voltage converter circuit 2 and the electronic control circuit 6, 7, 8, 9 are designed so that the generator 1 immediately after a start of the movement until the time of charging of the first capacitive element 10 on the predetermined value operates at a speed which is greater than the target speed of the generator 1. In this case, charging of the first capacitive component 10 takes place via the first diode 14.
  • the voltage value of the first capacitive component 10 which is sufficient for operating the first comparator 21 and for operating a second comparator 20 present in the voltage tripler circuit 12, 13, 15, 16, 17, 18, 20, 23 and explained in more detail below is shown in FIG 0.6 V.
  • the voltage drop across the first diode 14 is 400 mV.
  • the first comparator 21 closes, as soon as the voltage supplied by the voltage tripler circuit 12, 13, 15, 16, 17, 18, 20, 23 is higher than the voltage of the first capacitive element 10, the first switch 19, i. he opens the first field effect transistor.
  • the voltage drop across the channel of the first field effect transistor is only 10 mV. The voltage loss is thus significantly reduced.
  • the first comparator 21 closes the first field effect transistor. If the voltage supplied by the voltage tripler circuit 12, 13, 15, 16, 17, 18, 20, 23 again increases to a sufficiently large value, the first comparator 21 opens the first field-effect transistor again and so on. The charging of the first capacitive element 10 thus takes place only in the start-up phase of the movement on the afflicted with a highchrosveriust first diode 14.
  • the voltage converter circuit 2 in addition to its rectifier function must also fulfill aaasvervielfacherfunktion, including the already mentioned,tosvervielfacherscaria 12, 13, 15, 16, 17, 18, 20, 23 is used.
  • the voltage multiplier circuit 12, 13, 15, 16, 17, 18, 20, 23 is a voltage tripler circuit. Two different embodiments of the voltage tripler circuit are shown in FIGS.
  • a first embodiment of the voltage tripler circuit (see FIG. 2) further comprises a parallel connection of a second diode 12 and a second switch 17 and a parallel connection of a third diode 23 and a third switch 18.
  • the parallel connection of the second diode 12 and the second switch 17 is connected in series between the generator-side terminal of the second capacitive component 15 and the load-side terminal of the third capacitive component 16.
  • the parallel connection of the third diode 23 and the third switch 18 is connected in series between the generator-side terminal of the third capacitive element 16 and the load-side terminal of the second capacitive element 15.
  • the first embodiment of the voltage tripler circuit also has a fourth diode 13 connected in series between the load-side terminals of the second and third capacitive components 15, 16 ,
  • the second, the third and the fourth diode 12, 23, 13 are connected in the same forward direction, and the first diode 14 is connected in the opposite direction of passage.
  • the second comparator 20 compares the electrical potential at the connected to the second capacitive element 15 terminal of the generator 1 with the electrical potential at the load-side terminal of the third capacitive element 16.
  • the second and / or the third switch 17, 18 is through the second comparator 20 closed only when the voltage of the first capacitive Component 10 is sufficient for operating the second comparator 20 and provided by the generator 1 available electrical potential for charging the second and the third capacitive element 15, 16 is high enough.
  • the second switch 17 is a second field effect transistor
  • the third switch 18 is a third field effect transistor.
  • the second field effect transistor is connected so that in its locked state, part of its structure acts as a second diode 12.
  • the third field effect transistor is switched so that in its locked state, a part of its structure acts as a third diode 23.
  • the second field effect transistor and the third field effect transistor are initially blocked.
  • the charging of the second capacitive component 15 and of the third capacitive component 16 takes place via the second, third and fourth diode 12, 23, 13.
  • the second comparator 20 opens the second field effect transistor and the third field effect transistor.
  • the charging of the second and the third capacitive component 15, 16 now takes place via the second field effect transistor and the third field effect transistor.
  • the reduction of the voltage losses is analogous to the above-described reduction of the voltage loss during the transition from the first diode 14 to the first field effect transistor.
  • the opening and closing of the second and the third field effect transistor by the second comparator 20 In an analogous manner, the opening and closing of the second and the third field effect transistor by the second comparator 20. If the voltage supplied by the generator 1 falls below the voltage of the third capacitive element 16, the second comparator 20 blocks the second and the third field effect transistor , As the voltage supplied by the generator 1 increases above the voltage of the third capacitive device 16, the second and third field effect transistors are opened, i. the second and third switches 17, 18 are closed. Compared to pure diode use thus results in the dosesverdreifachersciens a more economical use of the energy reserve of the movement, whereby the power reserve is increased.
  • FIG. 3 shows a second embodiment of the voltage tripler circuit in which, unlike the first embodiment of the voltage tripler circuit, the circuit branch containing the fourth diode 13 is missing. Since the fourth diode 13 is not absolutely necessary for the operation of the voltage tripler circuit, the second embodiment of the voltage tripler circuit also ensures reliable operation of the voltage converter circuit 2. Of course, the respective existing diodes always have to be suitably adapted to the current circuit environment in their dimensioning. The same applies to the third embodiment of the voltage tripler circuit shown in FIG. 4, which has only the circuit branch with the fourth diode 13, but not the circuit branches with the second diode 12 and the third diode 23.
  • the second switch 17 occurs alone or in the fourth embodiment of the voltage tripler circuit third switch 18 alone.
  • the voltage converter circuit 2 and the electronic control circuit 6, 7, 8, 9 are tuned such that the power consumption of the Energydissipationsscrien 9 assumes a minimum value while any of the capacitive devices 10, 15, 16 is charged.
  • the voltage converter circuit 2 and the electronic control circuit 6, 7, 8, 9 are designed so that the power consumption of the Energydissipationsscrien 9 at intervals of 3 x 10 -2 s regularly for 5 x 10 -4 s assumes a minimum value to the comparators 20th , 21 to allow a potential comparison according to their function. If the potential comparison were carried out at a generator load that is above the minimum load of the generator 1, then the comparators 20, 21 with respect to the charging possibilities of the capacitive components 10, 15, 16 would come to wrong conclusions, because they would be compared to the generator voltage at minimum load detect reduced generator voltage.
