Definitions

  • the present invention relates to a timepiece comprising an electrical energy generator comprising a rotor and means for supplying electrical energy in response to a rotation of the rotor, and being regulated by an electronic circuit comprising means for braking the rotor of the generator.
  • a mechanical energy source drives an electrical energy generator to power the electronic circuit.
  • the generator rotor itself can be braked by the electronic circuit in order to regulate mechanical movement by slaving it, for example, on the frequency of a quartz.
  • the interest of these timepieces is to have a very precise movement, regulated by quartz or other, without requiring a battery or accumulator with limited lifespan.
  • Such a timepiece is described for example in US-A-3,937,001 in which the pulsation of the alternating voltage of the generator is compared to the frequency of a quartz.
  • the rotor is braked by short-circuiting the generator by a resistor. But when the movement takes a certain advance, the braking time of the generator rotor can become very important, at the risk of seeing the supply voltage coming from the generator becoming insufficient for the electronic circuit.
  • FIGS. 1 to 4 illustrate the shape of the alternating voltage Ug and measurement pulses SM obtained with two threshold comparators of the state of the art. Measurement results carried out with a comparator with zero voltage threshold are illustrated in FIGS. 1 and 2.
  • FIG. 1 represents the evolution of the voltage Ug as a function of time, the value 0 of the voltage corresponding to the zero threshold.
  • FIG. 2 represents, as a function of time, the pulses SM at the output of the zero threshold comparator, the measurement signal SM varying from a state "0" to a state "1" according to the result of the comparison.
  • an electrical parasite on the voltage Ug, at time t1 causes the appearance of a parasitic pulse I1 on the measurement signal SM. This electrical noise can simply be a transfer of mass noise.
  • the comparator threshold must fulfill two contradictory conditions. On the one hand, it must be high enough to mask the parasitic pulses. On the other hand, it must be low enough for the braking pulses to appear when the generator voltage is low, as we have seen previously.
  • Figures 3 and 4 are shown similarly to Figures 1 and 2 of the measurement results obtained with a high threshold comparator. Equivalently, the comparator could be a Schmidt amplifier with two thresholds of separated values.
  • the threshold Ut is shown in dotted lines on the timing diagram of the voltage Ug of the generator, see FIG. 3. We thus see a weakening of the voltage of the generator Ug during braking at time t4, and the appearance of double pulses I4 and I5 (see Figure 4), which is the opposite of the desired goal.
  • An object of the present invention is to stabilize the operation of a timepiece with mechanical movement regulated by an electronic circuit.
  • an object of the invention is to know the origin of such malfunctions and to remedy them.
  • Another object is to produce a miniature timepiece whose electronic circuit is simple and reliable.
  • the thresholds of the detection circuits used previously depend in fact on the value of the supply voltage.
  • the weakening of the generator voltage is enough to cause the comparator threshold to drift, which then generates a new pulse.
  • the comparator delivers double pulses instead of delivering only one.
  • the drop in voltage Ug supplied by the generator can reach a value greater than the positive threshold Uth of the comparator, thus triggering the appearance of a parasitic pulse. This phenomenon occurs only during the braking command, therefore just after the appearance of the first pulse.
  • a timepiece comprising an electrical energy generator comprising a rotor and means for supplying said electrical energy in response to a rotation of said rotor, a source of mechanical energy mechanically coupled to said rotor to drive it in rotation, measuring means coupled to said generator for generating pulses for measuring the pulsation of an alternating voltage supplied by the generator which corresponds to the pulsation of the rotor, braking means responding to a braking command for applying to said rotor a braking torque, and an electronic circuit comprising reference means for producing a signal having a reference frequency, and servo means arranged to control said means of braking when said measurement pulses are ahead of said reference signal of so that the reference frequency regulates the pulsation of said rotor and said mechanical source, this part being characterized in that said electronic circuit further comprises means (Inh) synchronous for the measurement pulses and arranged so that a doubling of said measurement pulses is deleted.
  • the detection of the measurement pulses is inhibited, so as to eliminate such duplication of pulses without significantly delaying the braking by relative to the change in sign of the generator voltage.
  • the invention provides that the inhibition means are correlated with a braking command provided by the control loop.
  • a preferred embodiment is characterized in that the inhibition means generate a braking command, the timing of this command being controlled by the servo loop.
  • the inhibition means comprise a time base and respond to the appearance or the disappearance of a measurement pulse.
  • the electromechanical part of the timepiece according to the invention is shown diagrammatically in FIG. 5. It comprises a source 2 of mechanical energy such as a spiral spring, coupled by means of gear trains 4 symbolized by lines mixed with means for displaying the time, like dial hands, the source 2 of mechanical energy also being coupled to a rotor 3a of an electrical energy generator 3.
  • the generator 3 also comprises an inductive coil 3b, the rotor 3a comprising a bipolar magnet conventionally represented by an arrow. This part will not be described in detail since it can be carried out in various ways, well known to specialists.
  • the source 2 of mechanical energy drives the rotation of the rotor 3a and an alternating voltage Ug appears at the terminals B0, B1 of the coil 3b.
  • the terminal B0 is considered as the reference terminal having a reference potential V 0 .
  • This alternating voltage Ug is applied to a rectifier 5 to supply direct voltage to an electronic circuit 1 for regulating movement.
  • a preferred embodiment example of a rectifier will be indicated later.
  • the electronic circuit 1 can regulate the mechanical movement of the timepiece by acting on the braking means of the rotor 3a of the generator 3 provided for this purpose.
  • the clockwork will indicate the current time when the rotor rotates at a given speed, which we will call normal speed.
  • the timepiece also includes means for measuring the speed of movement. They are preferably made up of means for measuring the pulsation of the rotor.
  • the invention seeks to obtain measurement pulses which correspond well to each pulse of the rotor, for example one pulse per revolution. These measurement pulses are in fact processed by the electronic circuit 1 in order to measure the drift of the movement and possibly provide a braking command. These measurement means and the processing of the pulses will be detailed with the electronic circuit.
  • Braking is obtained by short-circuiting the coil 3b of the generator 3.
  • the electric current then flowing in this bypass causes indeed the appearance of a magnetic field opposing the cause of the current therefore opposing the movement of the rotor .
  • the preferred embodiment of the invention provides an electronic switch K connected directly between the two terminals B0, B1 of the coil 3b of the generator. This gives very powerful braking.
  • the electronic switch K advantageously consists of a bipolar or field effect transistor, as explained in the document EP-A-0 679 968 mentioned above. Other equivalents are well known to specialists. The operation of this electronic switch K will not be detailed here.
  • FIG. 3 already described above, shows for example the shape of the alternating voltage Ug during a braking cycle, to be compared with FIG. 1 representing the voltage Ug in the absence of braking.
  • t0-t6 there is a time interval t4-t5, during which the braking is controlled, the short-circuited generator supplies all its energy to the switch K.
  • document EP-A-0 679 968 indicates that the braking command must be applied at times when the voltage Ug is close to 0 and during a short time interval, preferably less than 1/8 of the pulse of the alternating voltage Ug.
  • the rotor 3a thus has a normal speed of four revolutions per second and the duration of the braking pulses applied to the switch K is limited to approximately 5 ms, or 1/50 of the 250 ms pulsation of Ug voltage.
  • the electronic circuit 1 for regulating the movement of the timepiece consists mainly of an oscillator Osc providing a signal having a base frequency FO, of measurement means, referenced Trig and Inh, the pulsation of the rotor 3a and a frequency servo circuit, controlling a brake control of the rotor.
  • the frequency control circuit controls the braking when measurement pulses IN supplied by the measurement means Trig, Inh, and having a frequency corresponding to the pulsation of the rotor, are in advance with respect to pulses, referenced FR, supplied by the oscillator Osc, and having a reference frequency derived from the base frequency FO of the oscillator Osc, for example by dividing the signal FO in order to obtain a signal having the reference frequency.
  • the servo circuit preferably comprises a frequency corrector Div which shapes the signal having a base frequency FO and delivers pulses at a reference frequency FR.
  • the Div corrector can simply be a frequency divider circuit, well known to specialists and will therefore not be detailed here.
  • pulses of intermediate frequency F1 can be extracted from such circuits.
  • the oscillator Osc is a quartz having a natural frequency FO of 32,768 Hz.
  • the divider Div divides the signal having the frequency FO in order to obtain a series of pulses FR having a reference frequency of 4 Hz corresponding to the normal pulsation of the rotor.
  • F1 pulses with an intermediate frequency of 4,096 Hz can also be extracted from the divider.
  • these values are given only by way of example.
  • F1 pulses which here therefore have a period of 0.244 ms, are intended to serve as a time base or as a time delay for the abovementioned braking command and to clock all the logic.
  • the servo circuit further includes a comparator, referenced Cmp, delivering an AV signal indicating the advance (or delay) of the movement with respect to the reference frequency FR.
  • This comparator Cmp can for example be an up-down counter, or reversible counter, totaling the difference in the number of measurement pulses IN, received on its input + " , and the number of FR reference pulses received on its input - " , as described in the document EP-A-0 679 968 mentioned above.
  • the state or the level of the AV signal available at the output of the comparator Cmp then indicates whether the rotor pulses are ahead or not of the reference frequency FR.
  • the servo circuit finally includes a timer Tmr, or register, delivering pulses of determined duration.
  • One of the two inputs of the timer Tmr is connected to the output of the circuit Inh, and the other input receives from the divider Div the pulses Fi used to determine the duration of the output pulses.
  • the timer also includes a validation terminal receiving the AV signal from the comparator Cmp.
  • the timer Tmr delivers on its exit braking pulses, referenced IF, of fixed duration after the appearance of a measurement pulse IN, if however the signal AV indicates that the pulsations of the rotor are ahead of the reference frequency FR.
  • braking will indeed have a duration of less than 5 ms, by programming an internal timer counter Tmr counting twenty F1 pulses having a period of 0.244 ms to generate a braking pulse IF therefore having a duration of 4 , 88 ms.
  • timer Tmr Preferred embodiments of timer Tmr will be detailed after the description of the means for measuring the pulsation of the rotor.
  • FIG. 6 represents an example of a timing diagram of the alternating voltage Ug delivered by the generator 3 when braking pulses are applied.
  • two threshold voltage levels Uth and Utb of reduced value compared to the amplitude of the voltage Ug are positive, slightly higher than the reference value 0 of the alternating voltage Ug.
  • the threshold Utb is negative, preferably, symmetrical to the threshold Uth with respect to the voltage 0.
  • the invention in fact provides that the pulsation measurement means comprise a hysteresis amplifier or "trigger" from Schmidt, referenced Trig in FIG. 5.
  • FIG. 7 shows a timing diagram of pulses obtained at the output of the Trig amplifier.
  • the amplifier output IM goes to a first level (state 0) from time b2 at which the input voltage Ug becomes lower than the lower threshold Utb; the output IM remains at this first level as long as the voltage Ug is not greater than the upper threshold Uth.
  • Trig with double threshold Trig Uth, Utb does not record the parasites of tension lower than the difference of the thresholds Uth - Utb.
  • Schmidt trigger with positive threshold Uth and negative threshold Utb should not be sensitive to the return of voltage Ug to the value 0 during braking periods.
  • the electronic circuit 1 preferably has a symmetrical continuous supply V-, V0, V +.
  • a good symmetrical supply comprises a generator at midpoint and a simple rectifier with a capacitor between two outputs V + and V-, the reference output V0 being taken at midpoint.
  • the preferred embodiment of the invention comprises a symmetrical rectifier 5 as illustrated in FIG. 5.
  • This rectifier comprises in particular a reference output Vo connected to the reference terminal B0 of the generator 3, and two capacitors disposed respectively between a voltage output V + or V-, and the output V0.
  • the operation of the rectifier circuit 5 intended to regulate the continuous supply of the electronic circuit 1 will not be described in detail since it can be carried out in various ways well known to specialists.
  • each capacitor is recharged at each half-wave substantially at the level of the peak value of the alternating voltage Ug.
  • FIGS. 6 to 11 A braking cycle is for example represented in FIG. 10 by the state "1" of the AV signal. The phenomenon seems to be due to the drift of the Uth and Utb thresholds of the Schmidt Trig "trigger". It is observed in fact that there is no duplication of the pulse at the start of the braking cycle.
  • FIG. 7 shows for example the absence of doubling at the start of the pulse H3, at the time of the first braking pulse F3, shown diagrammatically in FIG. 11.
  • the splitting of the pulse H3-H5 appears only at the second braking pulse F4. In fact, the peak value of the alternating voltage Ug is reduced after the first braking pulse F3.
  • the value of the rectified voltage V + becomes weaker. This drift in the supply voltage seems to cause a drift in the thresholds Uth and Utb of the "trigger" Trig. Thus, it has been observed that, at the next braking pulse F4, the drop in voltage Ug can reach a value greater than the threshold Uth, thus triggering the appearance of a parasitic pulse H5 represented in FIG. 7.
  • the phenomenon can also be caused by the existence of a certain waste voltage across the terminals of switch K (see FIG. 5). This waste voltage could prevent the Ug voltage from returning to a strictly zero value.
  • the invention provides means for synchronous inhibition of the measurement pulses.
  • the electronic circuit l further comprises a synchronous inhibition circuit Inh receiving the measurement pulses IM delivered by the threshold comparator Trig, the assembly thus constituting the means for measuring the pulsation of the rotor 3a.
  • synchronous inhibition will be understood as an inhibition triggered by signals, preferably by pulses internal to the system formed by the timepiece, its generator, the electronic circuit and its oscillator.
  • the inhibition of measurement pulses may be synchronized with the pulses themselves, a first pulse triggering the inhibition of the appearance of the following pulses.
  • the present request is for any "synchronous inhibition" without specifying the source of synchronization .
  • the inhibition circuit Inh comprises a time base (internal or external) and, normally, it transmits the measurement pulses IM coming from the amplifier Trig directly to the timer Tmr. However, when the inhibition circuit Inh is activated, the circuit no longer transmits the IM ⁇ pulses during an inhibition period.
  • the inhibition begins when a pulse appears and / or disappears, i.e. the inhibition circuit reacts on the rising and falling edges of the IM pulses, and its duration activation t i is timed by its time base.
  • FIG. 6 and to FIGS. 7, and 8 which respectively represent the different pulses transmitted by the amplifier Trig (FIG. 7) and by the inhibition circuit Inh (FIG.
  • the circuit of inhibition normally transmits the measurement pulses H1, H3 and H7, respectively as pulses M1, M3 and M5, because their transitions at times b2, h3, b4, h7 are separated by time intervals greater than the inhibition time ti. But this inhibition circuit does not transmit the parasitic pulse H5 which appears during the inhibition time ti starting at the falling edge (time b4) of the pulse H3, see Figure 8.
  • the inhibition circuit generates a normal pulse IN of determined duration at each edge of measurement pulse IM unless this edge appears during a normal pulse IN.
  • Such an inhibition circuit can be implemented analogously to the aforementioned timer Tmr.
  • the Inh circuit includes, for example, a multivibrator monostable sensitive to the transitions of the IM measurement pulses applied to its input. At the rising edge of a pulse IM, the monostable thus delivers at output a normal pulse IN of determined duration. Similarly, at the falling edge of a pulse IM, the monostable delivers another normal pulse IN of fixed duration.
  • the inhibition circuit receives on an input pulses IF, represented in FIG. 11, each being a braking command for braking the rotor of the generator, coming from the timer Tmr and the inhibition corresponds to the braking duration tf, see Figure 11.
  • the parasitic splitting pulses appear only during braking. Synchronous inhibition is thus achieved with the advantage of simplicity.
  • the preferred embodiment of the invention however comprises an inhibition command II of duration greater than the braking command IF, and covering all the braking instants.
  • the inhibition pulse II thus covers the instants following the end of the braking pulse IF and the appearance of pulse II possibly precedes the appearance of this pulse IF.
  • This "overflow" guarantees that delays in propagation of inhibition or braking or Ug voltage do not yet trigger spurious pulses.
  • the timer Tmr has two outputs which deliver a muting pulse II and a correlated braking pulse IF.
  • correlation designates the simultaneous appearance, or with a substantially constant time delay, of two physical phenomena such as signals or pulses. Note however that these two phenomena can have different durations. For example, temporarily correlated pulses can have different widths, which is well known to those skilled in the art.
  • the timer Tmr receives the pulses F1 of period 0.244 ms on a first input connected to the output of the divider Div.
  • a normal pulse IN appears on the other input, which is connected to the output of the inhibition means, and if the state of the advance signal AV commands it by means of a pulse on the validation input of the timer (see Figure 5), the timer Tmr immediately delivers an inhibition pulse II.
