Definitions
- the present invention relates to an electronic module for regulation for mechanical watch movement, and a method of regulating the speed of a watch movement at mechanical winding by means of an electronic module.
- All watches need a power source to train the movement and move the hands.
- this energy is supplied by the user by winding the crown or, in the case of watches automatic, by the displacements of an oscillating mass caused by the movement of the wrist and allowing to tighten a spring.
- Patent CH597636 proposes a construction making it possible to completely remove the battery from a quartz watch.
- the energy produced by the user's movements is accumulated in a spring, then transmitted through a train of gears to the hands of the watch as well as to a generator which converts to electricity (alternative voltage source).
- This source of voltage is rectified to continuously supply an electronic circuit including a quartz oscillator.
- the electronic circuit regulates the operation of the watch by acting on the electrical torque applied to the generator.
- the electronic circuit brakes by short-circuiting it (all-or-nothing braking).
- the set speed ideal is provided by the quartz oscillator.
- the document EP-B1-0239820 describes a method for adjusting the speed of a generator in which the speed of the generator is also all-or-nothing adjusted using a brake control signal.
- the signal brake control is synchronized with a reference signal obtained at from a quartz oscillator. At each cycle of the reference signal, the brake control signal first goes from logic zero to logic state one then returns from logic state one to logic state zero.
- the brake control signal therefore only depends on the reference signal and is not synchronized with the measurement signal produced by the generator.
- the brake control pulses may sometimes occur at the most unfavorable time for the generator, by example when the voltage at the output terminals passes precisely through a maximum. As we will see later, this situation can cause abrupt stop of the watch.
- EP-B1-0679968 describes another control module allowing apply "all-or-nothing" braking to the generator.
- the control module sends pulses of very short commands which have the effect of short-circuiting the generator.
- Short-circuit braking is very brutal, the duration of the pulses braking is necessarily very brief.
- the control module described in this document has however the disadvantage of braking even when the AC voltage across the terminals of the generator goes through a maximum.
- the peak-to-peak voltage at generator output terminals is therefore reduced by this braking.
- the storage capacities can therefore only use a recharge voltage decreased. In order to maintain a sufficient supply voltage for the electronic circuit, so it is necessary to slightly oversize the generator or in any case to provide storage capacities of energy of sufficient value.
- EP-A2-1041464 describes a control module in which the brake is activated by means of brake pulse trains. Every impulse, the rotor is braked suddenly for a very short time, but nevertheless requiring acceleration between two pulses. The rotor therefore undergoes a multitude of accelerations and decelerations successive during each cycle. Furthermore, the circuit does not allow prevent a braking pulse from occurring when the voltage at the generator output goes through an extrema. Finally, the generation of these pulse trains requires complex combinatorial logic and consuming a large current.
- An object of the invention is to propose a new construction of a quartz watch regulator module without battery allowing eliminate the drawbacks of known constructions, in particular the problems of autonomy, volume or electrical storage in a battery electrochemical.
- Another object of the invention is to propose a new construction of a quartz watch control module without battery, allowing the peak voltage to be recovered with a minimum of losses peak produced by the generator to supply the circuit while avoiding abrupt rotor deceleration problems experienced by modules braking all-or-nothing by shorting the generator.
- Another aim is to improve the braking process with several levels suggested in EP-A1-816955 and to resolve in particular the peak-to-peak voltage drop problem caused by braking continued.
- Another object of the invention is to propose a new construction of quartz control module without battery which can be freely manufactured and marketed independently of technology offered by other manufacturers.
- a module regulating electronics for winding watch movement mechanical including a generator for converting energy mechanical provided by the mechanical watch movement in one signal measurement, an electronic circuit supplied by said generator and comprising a braking circuit for applying at least two separate braking torques not zero at said generator, said circuit electronic circuit further comprising a circuit for controlling the braking, so as to control the rotation speed of said generator, the braking torque selected by said dependent control circuit notably the advance of the generator, and in which the braking torque is reduced when said measurement signal passes through an extremum.
- this module of regulation has the particular advantage of reducing braking when the signal measurement goes through an extrema. It is thus possible to use the voltage peak-to-peak of the measurement signal to load the storage capacities with sufficient energy to supply the circuit.
- the circuit of braking allows at least two distinct braking couples to be applied non-zero, it is possible to reduce braking without interrupting it completely, and thus avoid the brutal decelerations typical of All-or-nothing braking systems.
- the braking is reduced for a fixed duration, or at least a limited duration, when the measurement signal passes through an extrema.
- the braking reduction time is chosen so that be sufficient to guarantee a full recharge of storage, while leaving a braking time long enough to allow precise regulation even with braking torques low.
- the braking torque is gradually reduced before said measurement signal passes through a extrema, then gradually restored after said measurement signal has gone through said extrema. This avoids all the jolts caused by sudden variations in the applied braking torque.
- FIG. 1 shows a block diagram of an electronic circuit 11 according to the invention.
- the circuit 11 is preferably made in the form of a discrete integrated circuit and is intended to be mounted on a module, for example on a printed circuit board, in a device electrically autonomous, for example a watch, a telephone laptop, calculator or pocket computer, prosthesis hearing or medical, etc.
- the module further comprises an electromechanical generator 1 intended to supply electrically the electronic circuit 11 and whose rotational speed must be regulated.
- the generator 1 is by example driven by the gear train (not shown) of the watch where it occupies the place and function usually devolved to anchor escapement.
- a spring (not shown) loaded by a pendulum (not shown) rotates the rotor of generator 1 by through the gear train.
- Generator 1 converts energy mechanical power received to supply circuit 11.
- circuit 11 manages to control the speed of rotation of the generator rotor so that it corresponds to a set speed given by a quartz oscillator 4.
- the generator is for example of the type described in patent EP-B1-0851322.
- the set frequency of the alternating voltage supplied by the generator is preferably of the form 2 n Hz, n being an integer.
- the generator output signal has a frequency of 16 Hz.
- the mechanical part of the watch corresponds to the state of the art described for example in the document CH597636.
- the generator 1 is for example of the asynchronous type and provides an alternating voltage between terminals G + and G- with a peak-to-peak voltage on the order of 0.4 Volts for example. Higher tension is not desirable because it would require the use of a generator with larger dimensions.
- Figure 4 illustrates the shape of the voltage G +, G-aux generator terminals.
- a rectifier and voltage multiplier 2 converts this AC voltage into a DC voltage Vdd approximately 1 Volt sufficient to supply circuit 11.
- the rectifier and multiplier 2 is for example of the type described in patent EP-B1-816955 already mentioned. It preferably uses a circuit allowing switch between diodes - during start-up - and transistors which have a much lower voltage drop, as described in the patent EP-B1-0848842.
- the rectifier and multiplier 2 loads a capacity of storage 10 which temporarily stores the electrical energy produced by the generator 1.
- the rectifier and multiplier 11 also uses two capacities 15 and 16.
- Capacities 10, 15, 16 are preferably produced under the form of discrete capacitors external to circuit 11, but could also in an alternative embodiment be integrated into this circuit.
- the rectifier and voltage multiplier 2 is preferably supplied with current by means of a current source 32 which produces different stabilized currents pp, pn. These currents are also used to supply other components of circuit 11.
- the circuit 11 illustrated comprises an energy dissipation circuit 9 directly connected to outputs G +, G- of generator 1.
- the circuit of energy dissipation could also be connected to the output of the rectifier and multiplier 2, for example in parallel with capacity 10.
- the energy dissipation circuit 9 is constituted in this example by a network of resistors connected in parallel and individually selectable. Braking torque applied to the generator rotor is varied by selecting the number of resistors connected. Circuit 9 could however also include other types of impedances or even active elements, for example controllable current sources.
- Circuit 11 has two pins for connecting an external frequency reference, for example a quartz 4, at the input of an oscillator 3.
- the oscillator 3 powers the quartz 4 by providing a feedback loop to stabilize the frequency of the quartz.
- the exit of the oscillator is a stable K32 reference signal with a frequency stable of 32KHz for example.
- This reference signal attacks a divider of frequency 5 which includes a series of flip-flops to provide an output rectangular setpoint signal H32 with a lower frequency, by example 32 Hz, as well as various other sampleup clock signals, sampledown and K1 whose role will be explained later in relation to the figure 7.
- the frequency divider 5 can preferably be configured after manufacturing and welding of quartz, to compensate for inaccuracies quartz and variations between different quartz.
- the circuit 11 further comprises a zero crossing detector 7 which generates a rectangular signal Gen as an output, illustrated in FIGS. 4 and 7, the state of which changes with each change of sign of the voltage between the terminals G +; G- generator output 1.
- the nominal frequency of the Gen signal is for example 16 Hertz.
- the zero crossing detector can be produced for example by means of a simple comparator which compares the voltage G + with the voltage G-.
- a hysteresis comparator will preferably be used with a positive threshold Up and a negative threshold Un in order to avoid generating spurious pulses when the signal at the generator output is noisy and passes through zero several times.
- An analog and / or digital filter can also be used to suppress spurious pulses caused by a noisy signal.
- the zero crossing detector 7 could include a digital filter which blocks all of the output pulses for a predefined duration, for example a duration slightly less than 1/64 th of a second, after each pulse.
- no filter is used in order to simplify the circuit and reduce its consumption.
- the Gen measurement signal at the output of the passage detector zeros 7 is supplied with the setpoint signal H32 to 32 Hertz at the input of a anti-coincidence circuit 8.
- Circuit 8 makes it possible to prevent the state of the counter 6 described below does not take an indefinite value when a pulse up and pulse down are applied simultaneously.
- the Figure 7 illustrates with timing diagrams an example of operation of this circuit. It uses two sampleup and sampledown signals generated by the frequency divider 5.
- the sampleup and sampledown signals are rectangular signals with a frequency of at least 64 Hertz, for example a frequency of 1 Kilohertz, and a very low cycle ratio; the phase shift between sampleup and sampledown is 180 degrees.
- the circuit of coincidence 8 generates a pulse H32 'generated during the first sampledown pulse after each rising edge of signal H32 to 32 Hertz.
- the frequency of the pulses H32 ′ is therefore also 32 Hertz, but the duty cycle is lower than that of H32 and the phase is set on that of the sampledown signal.
- the anti-coincidence circuit also generates a Gen 'pulse during the first sampleup pulse after each rising edge or down from Gen signal.
- the frequency of the Gen 'pulse train is therefore double that of the Gen pulse train.
- the frequency of the Gen 'pulses is 32 Hertz and their phase set on that sampleup pulses.
- phase shift between the sampling signals allows ensure that the H32 'and Gen' pulses are not produced simultaneously.
- Sampling in the anti-coincidence circuit can be done very simply using rockers. Other types of tours can also be used as part of this invention.
- the anti-coincidence circuit outputs two trains of Gen 'and H32' pulses whose frequency corresponds respectively to double that of the measurement signal from generator 1 and that of the setpoint signal from the quartz oscillator 3, 4.
- the Gen 'and H32' pulse trains have therefore approximately the same frequency and a phase shift.
- Pulse trains up and down as well modulated by circuit 12 are supplied to the incrementation inputs up respectively at the down decrementing input of a counter bidirectional 6 to eight bits.
- the state of counter 6 can take any which value counts between 0 and 255; this value is incremented each time rising edge of the signal on the input up and decremented on each edge amount of signal down.
- the counter 6 is thus incremented on each rising edge or down from the Gen signal from generator 1 and decremented to each rising edge of the H32 setpoint signal produced by the quartz.
- the state of the counter corresponds to the difference between the number of pulses up and the number of pulses down and therefore depends in particular but not exclusively, the difference between the rotor advance in generator 1 and the reference given by quartz.
- the state of counter is modulated by circuit 12 and also depends on the phase instantaneous measurement signal Gen.
- the state of counter 6 is represented by 8 output bits B1 to B8 which control the energy dissipation circuit 9, as seen in particular in FIG. 2.
- the energy dissipation circuit comprises several resistors 910 to 915 connected in parallel and which can be individually selected by means of control transistors 900 to 905.
- the values of the different resistances correspond to the weights of the corresponding command bits.
- the most significant bits at the output of the counter actuate transistors making it possible to activate low value resistors, causing more intense braking of the rotor of the generator.
- Counter output signals B1 to B8 could directly control the control transistors 900 to 905.
- the number of output bits of the counter 6 is greater than the number of transistors and resistors in the energy dissipation circuit 9.
- the 8 output bits B1 to B8 control 6 resistors 910 to 915.
- Resistor 910 has for example a value of 120KOhms, while the more significant resistors 911 to 914 have decreasing values, for example a 911 resistance of 60 KOhms, 912 of 30 KOhms, 913 of 15 KOhms and 914 of 6 KOhms.
- the resistor 915 preferably has a very high value, for example 500 KOhms.
- Combinatorial logic (not shown) in circuit 9 calculates the six control signals of the six transistors 900 to 905 from the eight output signals of counter 6.
- the combinational logic makes it possible to disconnect all resistors 910 to 915 when bit B8 is inactive, i.e. when the value in the counter 6 is less than 128.
- Resistors are selectively connected only when B8 is active.
- the transistor 900 is on when the bit B1, controlling transistor 900 to connect the high resistance value 910, is active.
- the most significant bits B2 to B5 cause selection through transistors 901 to 904 respectively resistors 911 to 914.
- all resistors 910 to 915 are connected in parallel so as to minimize the impedance applied to the terminals of the generator. Braking is therefore maximum and constant when the value in the counter 6 exceeds 160, as illustrated in FIG. 3.
- the high value resistor 915 for example 500 KOhms, remains permanently connected when bit B8 is active. In regime of normal operation, a low current therefore flows continuously at through this resistance.
- the 915 resistor thus makes it possible to apply a permanent braking torque as the generator rotor advances from its ideal position, and to avoid rapid decelerations if the braking was completely interrupted.
- the braking torque applied thus depends exclusively on the count state of counter 6.
- the state of this counter depends on - in particular the advance of the rotor of generator 1 with respect to the speed of setpoint indicated by oscillator 3-4.
- the braking torque applied therefore increases when the rotor advances faster than the speed of setpoint.
- the use of high value impedances, greater than 100 KOhms, allows you to adjust the braking torque extremely fine and in particular to maintain a reduced braking torque but nevertheless permanently applied. It is thus possible to apply extremely progressive changes in braking torque at the rotor of the generator.
- Figure 3 illustrates the braking torque c applied to the rotor of the generator by circuit 9 according to the count value in the counter 6.
- the rotor is not braked when the value in the counter is less than 128. This avoids applying a torque of braking, even weak, at system start before the rotor has reaches and exceeds its set speed for a short time.
- the couple braking then increases gradually, significantly linear, until the counter reaches the value 159.
- counter 6 will be almost always in this linear zone between 128 and 159.
- the braking torque c then saturates to a large value when the counter reaches the value 160 and beyond.
- the braking torque applied for these values is enough to slow the rotor down quickly, even when it has been accelerated by a shock, so as to quickly bring the system back into the area linear between 128 and 159.
- the circuit 11 further comprises a braking modulation circuit 12 making it possible to modify the state of counter 6 according to the phase of the measurement signal [G +; G-] across the generator 1.
- the modulation circuit 12 includes a combinatorial logic, which is not detailed here but which is within reach skilled in the art, allowing to add pulses down ' additional decrement and additional up 'pulses increment of counter 6. Additional pulses down ' are introduced into the pulse train H32 'produced by the circuit 8, as can also be seen in Figure 4. The additional up 'pulses are introduced into the train of Gen 'pulses produced by the anti-coincidence circuit 8. Circuit 12 is arranged to add one or more additional pulses down '6 shortly before each signal extrema [G +; G-] and a number equivalent of increment pulses up 'just after each extrema of this signal.
- the modulation circuit 12 thus makes it possible to decrement momentarily counter 6, and therefore momentarily reduce the braking torque, at the extremes of the voltage [G +; G-] across the generator. It is thus possible to temporarily limit the fall of voltage across the generator, thus recovering a maximum voltage to recharge storage capacities 10, 15 16 and ensure sufficient power to the circuit.
- the down pulse train produced by the modulation circuit 12 is illustrated in FIG. 4.
- this train of pulses applied to the decrementing input of counter 6 comprises on the one hand H32 'pulses produced by the anti-coincidence circuit 8 from the H32 setpoint signal, and secondly additional pulses hatched down 'introduced by circuit 12 shortly before each extrema of the voltage G +; G-.
- Figure 4 further illustrates the up pulse train. applied to the increment input of counter 6.
- the up signal includes the Gen 'pulses produced by the anti-coincidence circuit 8 from the Gen measurement signal and additional hatched pulses up 'introduced by the circuit 12 shortly after each end of the voltage G +; G-.
- the modulation circuit 12 generates two additional pulses down 'and two additional pulses up' before respectively after each zero crossing of the signal produced by the generator 1.
- the first pulse down 'is generated after an interval of duration T1, for example 4 milliseconds, after detection of passage through zero of the voltage across generator 1 (taking into account the hysthérebene).
- the second pulse down 'is generated just after the first pulse down ', for example a millisecond later.
- the first pulse up 'is generated after an interval of duration T2, by example 8 milliseconds, after each Gen 'pulse.
- the second pulse up 'is generated just after the first pulse up' by example a millisecond later.
- the third line of the timing diagram in Figure 4 illustrates the evolution of the voltage between terminals G + and G- of generator 1.
- the regular curve represents the sinusoidal voltage that would be produced if no braking torque was applied by circuit 11; the plus curve jerky shows how this tension is reduced when a couple of braking corresponding to successive values count in counter 6 is applied to the generator.
- the generator rotor is ahead as in this figure, we see that the voltage [G +; G-] is reduced in permanence: circuit 11 brakes during the whole cycle. Braking torque applied is however temporarily reduced when the amplitude of the signal at the generator terminals is maximum in absolute value.
- the circuit is therefore capable of recharging the storage capacities 10, 15, 16 with a peak voltage close to the theoretical maximum.
- the fourth line of the timing diagram in Figure 4 illustrates the rectangular signal Gen at the output of the zero crossing detector 7.
- the zero crossing detector consists of a hysteresis comparator.
- Gen signal goes from logic state to state logic zero when when the voltage between terminals G + and G- of generator 1 drops below the negative value -Un and returns to logic state one when the voltage G +; G- reaches the positive threshold Up.
- the thresholds Up and Un have been greatly exaggerated in the figure but may, depending on the noise level on the input signal, be closer.
- Additional down 'and up' pulses are generated independently of the relative advance of the Gen measurement signal and the signal setpoint H32.
- the count state of counter 6 is therefore not representative of the difference between the number of H32 'reference pulses produced by the quartz oscillator 3, 4 and the number of Gen measurement pulses produced by the generator, but also depends on the phase signal G +, G- between the terminals of generator 1.
- the last line in Figure 4 does not represent a signal physical, but indicates the evolution of the count value in the counter bidirectional 6.
- the braking torque applied is, in the linear part in Figure 3, roughly proportional to this count value. This value is incremented with each up pulse and decremented with each pulse down. It can be seen that, at each half-cycle of the Gen signal, the count value is reduced and then gradually restored and for one limited time so as to gradually and smoothly reduce the braking torque applied when the voltage across the generator is maximum.
- the invention therefore makes it possible to apply a braking torque permanently to generator 1 which depends on the advance of the rotor and which is further modulated according to the instantaneous phase of the signal G +, G- at the terminals of the generator so as to optimize the load on the storage capacities 10, 15, 16 and without sudden variations in the applied braking torque.
- an up pulse does not trigger additional up 'and down' pulses only if the brake reduction interval caused by the zero crossing previous is completely finished.
- the duration of intervals T1 and T2 is made dependent on the frequency of the signal [G +; G].
- FIG. 5 illustrates an example of the evolution of the braking torque in which 4 additional pulses down 'and up' are used.
- FIG. 6 illustrates a variant of the invention in which the braking torque permanently applied to the generator is pulsed.
- the amplitude of the pulses, and / or the amplitude of a continuous component added to the pulses, and / or in the example illustrated the cycle ratio of pulses, depends on the value in counter 6. As in the previous examples, this value is modulated so as to reduce the braking, without interrupting it completely, when the amplitude of the voltage across the generator goes through an extrema. According to the invention, the braking torque C does not drop to zero, even between the different pulsed braking peaks.
- the braking torque can also vary from continuously, especially when the energy dissipation circuit is constituted by a controllable current source, or by using impedances whose value can be varied continuously.
- the braking torque is temporarily and gradually reduced by adding additional pulses down 'and up' at the input of the counter bidirectional 6. It would also be possible, within the framework of modifications to the reach of the skilled person, to act on the output of the counter 6 using a subtractor arranged to subtract for a limited time a fixed or variable value. In the same way, it would also be possible to act directly on the energy dissipation circuit 9 and to use by example an impedance or an impedance network of resulting value controllable in parallel or in series with other impedances. We could then order the value of this impedance so that it depends on the instantaneous phase of the voltage at the generator output, so that gradually increase the resulting impedance when the voltage at generator terminals goes through an extrema.
- control module The operation of the control module described above is integral type; the feedback applied in the form of a couple of braking at generator 1 depends in particular, but not exclusively, on the difference accumulated in counter 6 between the number of pulses up from the generator and the number of pulses down from the quartz oscillator.
- faster correction is desirable, for example example if it is important that the watch corrects walking errors very quickly in order to display a precise time at all times, it is also possible within the framework of this invention to apply a regulation proportional to the momentary rotor speed, even proportional to the derivative of this momentary speed, or even a combination between these different setting possibilities, for example a PID setting (Proportional-integral-differential).
