    Technical area
    The invention relates to an electronic feed circuit and electronic feed method for a clockwork.
    The invention relates in particular to a circuit and method for powering units that consume a lot of power over a short period of time. This circuit can be used, for example, in a mechanical watch with a power generator.
    State of the art
    Mechanical watches are driven by a mainspring. This spring is the motor of the mechanical watch: it is wound either manually or by wearing it on the wrist using the automatic winding mechanism of the watch and thus stores the energy. This is then continuously transferred to the gear train.
    [0004] The gear train is a type of gear mechanism that transmits and translates the great energy of the barrel to small wheels (minute, small bottom, seconds and escape wheels). The escapement acts as a link between the wheel train and the balance wheel and transfers the pulse from the barrel via the escape wheel and the armature to the balance wheel and keeps it swinging. The escapement, controlled by the regulating organ, releases and stops the gear train at very precise intervals.
    The control element comprises a spiral spring and a balance wheel. The balance wheel behaves like a pendulum, which is always returned to the rest position with the help of the spiral spring, thus ensuring that the clock runs smoothly. In most modern watches, the balance wheel oscillates at 4 Hz, i.e. 4 times per second or almost 345,600 times a day. These intervals cause the hands to indicate the "correct time" on the dial.
    A disadvantage of the mechanical watch compared to the electronic watch is that the rate of the wrist watch is adversely affected by changes in position, fluctuating temperature, magnetism, dust, and also by irregular winding and oiling.
    In order to improve the accuracy of mechanical watch movements, quartz-controlled mechanical watch movements have been developed. In such models, a conventional mechanical clockwork is controlled by an electronic control element, which is also fed with the energy of the mechanical clockwork.
    Figure 1 shows schematically the main components of the electronic circuit in such a quartz-controlled mechanical watch. The system comprises a generator 1 which is driven by the gear train of the clockwork and which regulates the rate of the clockwork. The generator supplies an alternating voltage with a frequency that depends on the rate of the clockwork. This alternating voltage is rectified by the rectifier 2 and possibly multiplied. A first capacitance C1 at the output of the rectifier or as part of the rectifier 2 stores the constant voltage Vdd with which an electronic control circuit 3 is fed. The control circuit 3 has a comparator logic circuit and an energy dissipation circuit which is connected to an output of the comparator logic circuit and whose power consumption can be controlled by the comparator logic circuit. The frequency at the output of the generator 1 is thus compared with the reference frequency which is generated by a quartz oscillator 4. The energy dissipation circuit at the output of generator 1 is controlled as a function of this comparison, so that the generator is braked if it rotates too quickly.
    An example of such a system is described in EP848842. In this system, an electromagnetic rotary machine is proposed as a generator, with a magnetized rotor which generates an alternating voltage in the coils of the stator when the rotor is driven by the gear train.
    WO2011 / 131784A describes another control element for a mechanical clockwork, in which the energy for the electronics of the control element is made available by the spiral spring. In a conventional mechanical watch, the spiral spring is replaced by a piezoelectric spiral spring. The piezo spiral spring generates an alternating voltage that is dependent on the oscillations of the balance wheel and / or the spiral spring. To regulate the oscillation frequency of the balance wheel, the alternating voltage is transmitted via an electrical connection to the electronic control circuit, which can change and thus regulate the stiffness of the balance spring and thus the frequency of the balance / balance spring oscillation system. Here, too, the electronic control circuit is only electrically fed by the named piezo coil spring, so that an additional battery is not required. So when the balance is set in motion, an alternating voltage is generated by the piezoelectric materials attached to the hairspring. The spiral spring thus functions as a power generator. The stiffness of the spiral spring is adjusted by changing the impedance at the output of the piezo spiral spring. In a preferred variant, this is achieved by adapting the value of a capacitance parallel to the piezo coil spring. The greater the value of the capacitance connected in parallel to the piezo coil spring, the lower the rigidity of the coil spring.
    In such quartz-controlled mechanical watches, the accuracy of the watch is given by the accuracy of the quartz oscillator. The accuracy of the quartz oscillator depends on the temperature. The electronic control circuit has only a small power consumption in both variants, on the order of 50-100nW.
    The accuracy of a clock that uses a quartz oscillator as a time signal can be significantly improved by using a temperature compensation circuit for the quartz oscillator. Such temperature compensation circuits are known, for example, from EP0032358B1.
    WO2008125646 also describes a circuit for temperature compensation of a quartz oscillator. A second oscillator with a linear frequency dependence on temperature is used in this circuit. The method is based on the fact that the number of pulses from the quartz crystal oscillator is determined for at least three different temperatures during a specific number of pulses from the second oscillator. A function for the temperature compensation of the quartz can then be calculated from the measured values, and the frequency of the quartz oscillator can be corrected accordingly when the temperature changes. In this way it can be ensured that the quartz oscillator maintains an oscillation frequency that is as stable as possible even when the temperature changes during operation.
    Such temperature compensation circuits are used with electronic clocks that are powered by a battery. In the case of watches whose electronics are supplied by an internal power generator, the energy required during compensation is too high. To determine the correction for the temperature compensation, the circuit for the temperature compensation can have a power consumption of several microwatts for a short time, that is to say 10 to 100 times higher than the average power consumption of the entire electronic circuit. But if the maximum charging power of the generator is only 500nW, the generator would be overloaded. The supply voltage of the electronic circuit would drop sharply, so that the electronic circuit could no longer be operated.
    Presentation of the invention
    It is an object of the invention to propose an improved electronic feed circuit to feed units in a clockwork which consume a lot of power over a short period of time.
    Another aim is to propose an electronic feed circuit that can feed a temperature compensation module even in generator clocks.
    This goal is achieved by a method to feed an electronic control circuit and an electronic module in a clockwork with a generator, wherein a control circuit peak current that is consumed by the control circuit is smaller than a module peak current that is generated by the electronic module ( 40) is consumed, with the following steps: during a first period a first amount of energy is used to feed this control circuit, and a second amount of energy is stored in a third capacity, the second amount of energy being smaller than the first amount of energy, the first and the second amount of energy is provided by the generator; after a plurality of first periods, the third capacitance is used to supply the second peak current to the electronic module, and the electronic module (40) is fed with the module peak current from the third capacitance (C3)
    Thus, the energy that is required to feed the second module with the second peak current is saved over several periods in the third capacity, and only used when the second peak current has to be delivered or can be delivered.
    Since the third capacity is charged over several periods, the charging current for this capacity remains relatively small, so that the remaining current remains sufficient to feed the electronic control circuit during each period.
    In one embodiment, a first capacitance is charged with a first current during each first period. This first capacitance feeds the control circuit. In addition, a second capacitance is charged with a second current during each first period. The second capacitance is smaller than the first capacitance and the second current is smaller than the first current. During the first period, for example at the end of each first period or as soon as the voltage across the first or second capacitance reaches a predetermined threshold, the charge in the second capacitance is transferred to the third capacitance.
    The second small capacity thus serves as a charge pump to store a small amount of energy during each period and then to transfer it to the third capacity.
    [0022] Further advantageous embodiments are specified in the dependent claims.
    Brief description of the figures
    The invention is explained in more detail with reference to the accompanying figures, wherein: Figure 1 shows schematically the components of an electronic control circuit that can be used in a quartz-controlled clockwork according to the invention. FIG. 2 shows schematically a first example of a feed circuit which can be used in an electronic control circuit according to FIG. 1 to feed the electronic control circuit and an electronic module. FIG. 3 schematically shows a second example of a feed circuit which can be used in an electronic control circuit according to FIG. 1 to feed the electronic control circuit and an electronic module.
    Ways of Carrying Out the Invention
    The already described Figure 1 shows a control circuit in which an electronic module, for example a temperature compensation module, and a feed circuit according to the invention can be used. This control circuit can be, for example, the control circuit according to WO2011 / 131784A or according to EP848842. The generator 1 can thus comprise a lathe operated by the gear train, a piezo spiral spring, or else a solar cell, a Peltier element, etc.
    FIG. 2 shows a first example of a feed circuit according to a first embodiment of the invention. This feed circuit is used to supply the control circuit 3 of FIG. 1 and an electronic module (not shown), for example a quartz temperature compensation element, with current.
    With this circuit, the problem of the lack of power of the microgenerator for the operation of the temperature compensation circuit is solved according to the invention by the energy for the operation of the temperature compensation from a third capacitor C3 with a relatively large capacity, for example a capacity of more than 2uF, for example 15uF. The third capacitance C3 is thus larger, preferably substantially larger, than the first capacitance C1, which temporarily stores the energy supplied by the generator 1 for the operation of the electronic control circuit 3. This first capacitance C1 preferably has a value between 100 and 2000 nF, for example 1 uF. It can thus be ensured that the operation of the temperature compensation circuit 40 with briefly high currents does not lead to a disruption of the supply voltage of the electronic control circuit 3.
    In this figure, as well as in the embodiment of FIG. 3, the first capacitance C1 can be part of the rectifier 2 of FIG. The temperature compensation circuit 40 can be part of the control circuit 3 or a separate component. All electronic components, with the exception of the larger capacitances C1, C3 and possibly C2, can be implemented as a single component, for example as a chip.
    The problem of the lack of power of the microgenerator 1 can be solved according to the invention in that energy is temporarily stored on a third large capacitor C3, for example with a capacity of 15uF. The temperature compensation circuit 40 is then fed by this capacitor C3.
    The generator 1, be it a piezo coil spring or an alternating current generator as described in EP848842 or WO2011 / 131784A, can only deliver a relatively small electrical power of the order of 100-200nW. Of this, 50-100nW are required for the operation of the electronic control circuit 3 with the stable crystal oscillator 4. In addition, free power is still required so that the speed of the generator can be regulated, as described in EP848842, or so that the stiffness of the piezo coil spring can be changed, as described in WO2011 / 131784A.
    If now the large third capacitor C3, in order to charge it, were directly connected to the generator, this would have the consequence that the generator would be loaded to the maximum. If the generator is a lathe, e.g. in EP848842, this would result in a maximum braking torque, so that the generator would turn too slowly and the time display would no longer be correct. With a piezo coil spring as a generator, the rigidity of the coil spring would be minimized, which in turn would result in the oscillation frequency of the unrest being too low, which in turn would result in an incorrect time display. Another problem would result from the fact that a maximum load on the generator 1 reduces its induced voltage. In the case of the piezo coil spring, this would be like a short circuit, the induced voltage would be so low that it would no longer be possible to operate the electronic control circuit.
    Since the temperature compensation does not have to be carried out continuously, but only after several first periods, for example every 8 minutes, and only runs for a short time, for example 500 ms, there is a relatively long second period, for example 8 Minutes, between each temperature compensation. During this second period, the large capacitor C3 can be slowly but steadily charged by transferring a relatively small amount of energy / charge to the large capacitor C3 during each first period. This can be done by using a relatively small capacitor C2, for example with a capacitance of less than 200 nF, for example 15nF, that is to say with a capacitance that is only one thousandth of the capacitance of the relatively large capacitor C3, to carry small charge packets transfer the large capacitor C3 during every first period.
    In a first phase of each first period P1, preferably when the average capacitance C1 is charged by the generator, during the first period P1, the switch T1 is closed and the switch T2 is open. This connects the first capacitor C1 and the second capacitor, preferably in parallel, and disconnects the third capacitor C3 from the second capacitor. Thus, during this phase, the small capacitance C2 is connected in parallel with the medium capacitance C1, and both are charged with the voltage Vdd from the rectifier 2. The control circuit 3 is then fed from C1 (and only insignificantly from C2).
    As soon as this charging process is completed, i.e. after the end of the first phase, the switch T1 is opened and the switch T2 is closed in a second phase of each first period P1. As a result, the first capacitor C1 is separated from the second capacitor, and the third capacitor C3 is connected to the second capacitor, preferably in parallel. The control circuit 3 is further fed by C1. The small capacitance C2 is thus connected in parallel to the large capacitance C3. Since the voltage on the small capacitance C2 is greater than the voltage on the large capacitance C3, the charge is transferred from the small capacitance C2 to the large capacitance C3.
    The switches T1 and T2 can be controlled by comparators to be switched as soon as the voltage Vdd reaches a predetermined threshold.
    In another embodiment, the switches T1 and T2 are switched without comparators. It is sufficient for the time being to connect the small capacitance C2 in parallel with the medium capacitance C1, and after a predetermined period P1 to open the switch T1 between the two capacitances C1, C2 in order to then connect the small capacitance C2 with the switch T2 in parallel with the large capacitance C3 to switch. After a predetermined period of time of, for example, 5 ms, the connection T2 between the large capacitance C3 and the small capacitance C2 is then disconnected, the small capacitance C2 is again connected in parallel with T1 to the medium capacitance C1. In this embodiment, the duration of the first phase and the second phase is predetermined within one period.
    In a variant, the switch T1 can be controlled with a signal from the rectifier. As soon as the capacitance C1 has reached a predetermined voltage, the connection between the rectifier and C1 is disconnected. This serves to prevent the capacitance C1 from being charged to a voltage that is too high. Depending on the amplitude of the unrest, the piezo coil spring generates a different voltage. The control circuit 3 is, however, operated advantageously with a constant voltage. As soon as the capacitance C1 is no longer connected to the rectifier 2, the connection between the capacitance C2 and the capacitance C1 is disconnected, and the capacitance C2 is connected to the capacitance C3. As soon as the capacitor C1 is recharged by the rectifier, C3 and C2 are disconnected and C2 is again connected to C1.
    The large capacitance C3 is thus incrementally charged by the small capacitance at each period P1. After a second predetermined period, for example 8 minutes, this capacitance C3 is used to feed the electronic module 40, for example a quartz temperature compensation element.
    A mechanical clockwork has a balance with a frequency of 4 Hz, for example. Thus, the duration of the first period P1, during which the average capacitance C1 is charged, is 1/8 second.
    If the temperature compensation is carried out, for example, every 8 minutes, this means that a second period P2 of 8 minutes is available to charge the large capacity C3. During a second period P2 of 480 seconds, there are thus 3,840 charging processes of 1/8 of a second. The large capacity C3 is charged with 3,840 small charge packets for 8 minutes. The generator 1 is only insignificantly loaded by the small charge packets, so there is no noticeable voltage drop of the generator 1 during the charging of the average capacitance C1, which supplies the control circuit chip with energy in continuous operation. In addition, the load on the generator 1 is constant, so that the time display is not significantly disturbed by the charging of the large capacitor C3.
    A problem could now arise in that a control circuit is operated with the lowest possible operating voltage, for example 0.9 or 1.0V, so that the power consumption of the electronic control circuit is as small as possible. However, according to WO2008 / 125646, an internal RC oscillator is used for temperature compensation of the quartz oscillator. At low voltages of 0.9-1.0V it can be difficult to operate an internal RC oscillator properly.
    This problem is solved according to Figure 3 by the electronic module 40 (for example a temperature compensation circuit) is fed with a higher voltage than the control circuit 3. In this embodiment, the small capacitor C2 is not directly parallel to the large capacitor after charging C3 switched, but first connected in series with the middle capacitor C1, in order to then connect the series circuit of the small C2 and the middle C1 capacitor in parallel to the large capacitor (C3). In the first phase of each period P1, switches T1 and T4 are closed; T5 is open so that C1 and C2 are connected in parallel and are charged by rectifier 2. In the second phase of each period, for example after a predetermined period of time, T1 and and T4 are opened and T5 is closed. The series connection of C1 and C2 is thus connected in parallel with C3.
    Since the voltages from the small C2 and middle C1 capacitors add up in this case, the large capacitor C3 is charged to twice the voltage from the small and middle capacitor, so that a higher voltage is available to feed the electronic module 40 .
    A voltage doubling circuit or even a voltage tripling circuit can also be used to further double or triple the supply voltage of the electronic module 40.
    An advantage of the circuit according to the invention is that the additional energy consumption of the circuit is only a few nW, for example 5-6nW, but that after 8 minutes enough energy is stored in the large capacitance C3 to then switch the temperature compensation circuit with a during 400-500ms Power consumption of 5-10uW to operate.
    Another advantage of the proposed solution is that no additional comparators are required and that only time windows and digital elements are used. The additional power required to switch the transistors for temperature compensation is negligible.
    It is advantageous if the temperature compensation circuit 40 is operated with a constant voltage. According to the invention, this can be achieved by connecting a linear regulator between the large capacitance C3 and the temperature compensation circuit 40, which ensures that the temperature compensation circuit 40 is fed with a regulated voltage. This ensures that the temperature compensation circuit 40 is operated with a constant voltage of, for example, 1.8V when the large capacitance C3 has been charged to, for example, 2V.
    When starting the entire electronic circuit, i.e. when the generator 1 does not supply any voltage, the mainspring must be wound. The generator begins to rotate or oscillate, generating an electrical voltage in the process. It must then be ensured that the electronic circuit can be started safely.
    For the circuit according to the invention with temperature compensation, power-on-reset circuits can be used, as known from EP848842 or WO2011 / 131784A, but adapted so that when starting up it is ensured that the large capacitance C3 is also charged to the necessary voltage. On the one hand, this can be done in that the large capacity is only charged when the electronic circuit 3 has already started, when the quartz oscillator 4 and all comparators are working, the time display is regulated, etc.
    In one embodiment, when the large capacity C3 is charged for the first time, the time window for charging is made significantly larger, for example by not charging the capacity C3 for 8 minutes and even after 8 minutes no temperature compensation of the quartz oscillator is carried out, but for example first after 16 minutes, or after a period longer than the usual period P2 between two temperature compensations. Then the large capacity C3 could be charged during the first 16 minutes after the start of the movement and the electronic circuit 3, with a small average power. This allows the time display to be adjusted quickly. So that the time display can be regulated, the middle capacitor C1, which feeds the electronic circuit 3 with the exception of the temperature compensation circuit 40, must first be charged.
    When starting the generator 1, the voltage across the large capacitance C3 is still small, so that there is a large voltage difference between the large capacitance C3 and the small capacitance C1. In order to keep the charging power as constant as possible when the large capacitance C3 is charged for the first time, the small capacitance C1 can only be charged at 2 Hz, ie 2x per second, during a first phase Q1 and connected in parallel with the capacitance C3. Small electrical charges are then transferred from the generator to the small capacitance C2 and from the small capacitance C2 to the large capacitance C3. As a result, the load on the generator 1 remains low.
    Thereafter, during a phase Q2, the large capacitance C3 can be charged at 4 Hz (or 4x per second), and then during a phase Q3 at 8 Hz. This ensures that the load on the generator remains as constant as possible when the large capacitor is charged for the first time. Only after the expiry of Q3 is temperature compensation carried out for the first time, and then during a period of time Q4, for example 8 minutes, the large capacitance C3 is again charged at 8 Hz, then temperature compensation carried out in order to charge the large capacitor again during Q4 and then temperature compensation to carry out etc.
    In a further embodiment, the large capacitance C3 is already charged when the circuit 3 is started up. However, this has the disadvantage that the time display will not be adjusted after a few seconds, but only after a few minutes.
    The principle presented, that during longer period P2 small energy packets, which are supplied by the generator 3, are charged to a large capacity C3, in order to then use the energy stored in the large capacity C3 for a short time to generate an electronic (part) To feed circuit 40, which has a significantly higher power consumption than can be supplied by generator 3, is not limited to the use of generator clocks and the operation of temperature compensation of a quartz oscillator. The circuit shown can also be used to power other circuits. In one embodiment, the electronic circuit 40 comprises a sensor, for example a temperature sensor, a magnetic sensor, or another sensor, in order to measure an external physical quantity periodically according to P2 or as required. In a further embodiment, the feed circuit according to the invention feeds a communication part, for example an NFC, Bluetooth, USB or ZigBee module, with which data can be received or sent.
    In the description, without restricting the invention, the terms capacitance and capacitor are used equivalently. The capacitances claimed can be implemented as capacitors, for example.
    When in this document of feeding an electronic control circuit or a module is spoken of, what is meant is to supply the electronic control circuit or the module with the necessary electrical energy.
