Definitions
- the present invention relates to a part electronic timepieces of the type comprising a source of energy formed by a spring barrel, winding manual or automatic, coupled to a current generator alternative intended to supply electronic circuits of the workpiece by means of a rectifier.
- this device works the way next.
- the generator directly coupled to the barrel tends to turn too fast and thus provide a tension whose frequency is higher than a setpoint of frequency derived from a working frequency standard based on a watchmaking quartz.
- the generator must therefore be braked, which is achieved by short-circuiting periodically its winding.
- the number of brakes required to keep generator running nominal is high at the start of disarming the spring and gradually decreases as the energy accumulated in the spring runs out.
- this number can thus be used to determine when the energy of the spring will no longer be sufficient to maintain the exact course of the timepiece.
- the number of brakes successive is counted for periods of time successive fixed duration and if during such a period the number becomes less than a predetermined value, we can then trigger a display device warning the user that the power reserve is going soon to be exhausted.
- Information can also be operated to display an indication of the number hours during which the power reserve will be still sufficient to allow time display correct.
- this earlier timepiece must have outside the hands indicating the time one other display device such as a counter behind which moves an indicator that needs to be trained specially, depending on the state of exhaustion of the power reserve.
- timepieces battery-powered electronics with a device for to indicate, by means of a particular movement of one hands in particular the second hands, the degree of battery depletion.
- these devices so that when the battery voltage goes down below a predetermined minimum value, it occurs a jump of the second hand which for example instead of beating the second, do both seconds a step of two seconds on the dial.
- the invention aims to provide a timepiece electronic generator driven by a barrel spring in which one can avoid the presence of a special display device of the depletion of the power reserve, but in which, on the contrary, can indicate this with a particular movement of the second hand as is the case in classic quartz timepieces driven by a motor and powered by a battery.
- the exceeding of second and third limit values allow to order the electric brake on the generator so that from a certain exhaustion of the power reserve of barrel, the second hand moves periodically from the start on an angle of several seconds inviting the wearer of the timepiece to wind the spring from the barrel.
- Figure 1 illustrates an example of torque evolution supplied by a barrel which can be used in a room electronic clockwork with generator according to the invention.
- the diagram is drawn in gr.mm according to the number of barrel turns, both during cocking and during the disarming of the spring.
- a tour of the barrel corresponds to a walking time of eight hours about the timepiece.
- Curve A corresponds to the winding, it starts from a point A1 of total relaxation of the spring and ends after reassembly during which the barrel makes seven turns, at a point A2 of maximum arming for which the potential torque of the barrel is about 1200 gr.mm.
- Curve B represents the disarming of the spring during which the barrel supplies energy to the room of watchmaking. This curve begins at point B1 at a torque value of around 1050 gr.mm (this reduction in torque relative to the value of point A2 is due to inevitable mechanical losses) and leads to a point B2 of total disarming of the spring, this point obviously coinciding with point A1.
- the diagram also indicates, by a dotted line T, a critical value of the couple (critical C).
- critical C a critical value of the couple
- this value may correspond to a frequency of the generator output voltage equal to 21.3 Hz.
- phase P FI extends over approximately 0.75 turn of the barrel, as shown by way of example in FIG. 1, and is followed by a phase known as "pronounced braking" P FP of the generator during which the the speed of rotation thereof is maintained at a value such that the rotation of the hands becomes practically imperceptible for the wearer of the timepiece.
- This phase extends until the energy accumulated in the spring is almost completely used up (in the example after completion of the seventh turn).
- the timepiece will always remain ready to restart if the spring is re-armed enough that the part is automatic or manual winding.
- the phase P FP can immediately follow the phase P FI or be distant from it by a certain time interval I, the latter case being represented on the figure 1.
- means may be provided in addition to "magnetically" brake the rotor of the generator for example by exerting a low magnetic positioning torque there, preferably using at least one fixed magnet placed in the vicinity of the rotor at a suitably chosen distance. This arrangement temporarily blocks the rotation of the barrel, while waiting for the spring to be reset again, either automatically or manually.
- FIG. 2 represents a simplified diagram of a timepiece according to the invention.
- the rotor includes a generator symbolized by the rectangle 1 comprising a magnetic rotor 2 and at least one winding 3.
- the rotor is mechanically coupled, for example through a cog 4 symbolized by lines in dotted, to a barrel 5 in which is housed a spring 6. It can be armed by a winding mechanism, manual or automatic, known per se and not shown on the figure.
- the cog 4 is also coupled to a game hour indicator hands composed of a 7 hour hands, 8 minute hand and a second hand 9. The hands are coupled between them in the usual way with the reports of gear reduction, rigidly linked to the rotor of generator 1. As a result, they rotate as long as the rotor 2 is in motion.
- the generator 1 delivers an alternating voltage at its terminals 1a and 1b at a frequency of 21.3 Hz (64/3 Hz) and with a maximum value of 1.2 Volt, for example.
- the generator 1 is connected to a rectifier, for example a full-wave rectifier 10, to the output of which an integrated circuit 11 is connected, certain components of which form a circuit regulating the speed of rotation of the generator 1.
- the integrated circuit 11 receives continuous potentials V DD and V SS . It should be noted that FIG. 2 represents of the integrated circuit 11 only the components which are essential for the implementation of the concept of the invention.
- a quartz 12 drives an oscillator that is part of the integrated circuit 11 by delivering a pulse signal from a frequency of 32,768 Hz to a frequency divider 13, the whole forming a time base.
- This divider includes a terminal 14 delivering a signal whose frequency corresponds to the nominal frequency that must deliver the generator 1 so that the needles 7, 8 and 9 indicate the exact time. In the example described, this nominal frequency is 21.3 Hz (64/3 / Hz).
- the output 14 is connected to the counting input 15 of a reversible counter 16.
- Terminal 1a of generator 1 is connected to one inputs of a comparator 17 whose other input is connected to a reference potential source 18 like the mass for example.
- the output of comparator 17 is connected at the countdown input 19 of the reversible counter 16.
- Comparator 17 delivers an output pulse to the reversible counter 16 as soon as the voltage on terminal 1a of the generator rises slightly above the potential mass. Therefore, in the example, assuming that generator 1 is rotating at exactly the speed nominal corresponding to a frequency of 21.3 Hz, the content of reversible counter 16 must be equal to zero at the end of each half-wave of the output voltage of the generator.
- the output of the reversible counter 16 is connected to a decision logic 20 which according to some predetermined criteria which we will come back to below, produces an output signal at terminal 21, the criteria being materialized by wiring a certain number of elementary doors that make up this logic of decision.
- a decision logic 20 which according to some predetermined criteria which we will come back to below, produces an output signal at terminal 21, the criteria being materialized by wiring a certain number of elementary doors that make up this logic of decision.
- the signal present on the output terminal 21 is applied to the control electrode of a component of switching 22 selectively controlling the braking of the generator 1.
- This switching component 22 can be a MOS transistor whose source-drain path is connected between terminals 1a and 1b of generator 1.
- the regulator circuit according to the invention makes also intervene a circuit 23 called "starting" that usually designated by POR circuit (acronym of the Anglo-Saxon expression Power-On-Reset).
- POR circuit anglo-Saxon expression Power-On-Reset
- POR circuit is normally expected in most integrated circuits and especially in those used in rooms electronic watchmaking, to position the components of the integrated circuit in a certain logical state so that when it is powered up, these components can start working with the right logical state.
- the circuit start-up 23 includes two outputs 23a and 23b complementary, changing logical level when the voltage supplied to the integrated circuit 11 crosses, respectively in one direction or the other a value predetermined.
- this value can be about 0.7 volts excluding the hysteresis that this signal can undergo.
- the output 23a of the starting circuit 23 is connected to the reversible counter 16 of which it puts the content has “1", when its logic level goes from "0" to "1".
- the output 23b is connected to a switching component 24 for pronounced braking control.
- the latter can be formed by a PMOS transistor whose drain-source path is connected in series with a resistor 25, all of these two components forming a shunt mounted in parallel on the supply terminals V DD and V SS of the circuit. integrated 11.
- the switching component is made conductive when the logic level at output 23b of the starting circuit 23 changes from "1" to "0".
- the functioning of the timepiece according to the invention is as follows.
- the regulator circuit according to the invention is responsible for limit the speed of rotation of generator 1, because the latter, in the absence of such a limitation, would have tendency to get carried away until exhaustion of energy accumulated in the spring while driving the needles high speed.
- the speed limit is operated thanks to the presence of the brake control transistor 22 which can short-circuit terminals 1a and 1b of the generator and therefore electrically brake it, when it receives a corresponding signal from the logic of decision 20.
- the regulator circuit constantly compares the standard frequency provided by the divider 13 to that of the voltage delivered to terminal 1a of generator 1 and analyzed by the comparator 17.
- this operating mode lasts for around 5.3 turns of barrel 5 (a little more than forty hours) to assume naturally the spring 6 has not been wound manually or automatically. As this time interval, recurrence of braking successive becomes increasingly weak. Note also that during this operating mode the setting in recurrent short-circuit of generator 1 by the transistor 22 will not disturb the operation of the integrated circuit 11, two smoothing capacitors (not shown) of relatively large capacity and planned in rectifier 10, making it possible to continuously supply the voltage necessary for this purpose.
- the generator rotates at a speed such that its frequency is no longer sufficient for that in the reversible counter 16 the pulses from the divider 13 are compensated by the pulses produced by the comparator 17.
- the voltage that the generator supplies to the integrated circuit 11 is still sufficient to make it work.
- the counter thus sees its content increase to a predetermined limit value corresponding for example to its total positive capacity (overflow of the counter).
- this value can be equal to 512, which corresponds, taking into account the frequency with which the signal on terminal 15 of counter 16 makes it progress, to approximately 24 seconds.
- the decision logic 20 is also wired to detect this predetermined limit value.
- the decision logic 20 turns on the transistor braking 22 to reduce the rotation speed of the generator 1. This one having rotated at a speed lower than the nominal speed while filling the up / down counter 16, hands 7, 8 and 9 have taken a delay from the exact time, equal to the time of filling it (24 seconds in the example).
- generator 1 can resume speed and voltage supplied to the integrated circuit 11 increase until the starting circuit 23 react again and change state in direction reverse the logic levels on its terminals 23a and 23b, while at the same time the integrated circuit 11 starts again to operate.
- FIG. 3 This figure represents in a) the evolution of the logic level of the output 23a of the starting circuit 23 at this stage of operation.
- Diagram b) of FIG. 3 shows how the number N contained in the reversible counter 16 can evolve (curve C) from the moment when the signals POR on the terminals 23a and 23b change state in the opposite direction as we have just describe it. This moment is indicated by the time t 0 in FIG. 3 in b).
- the signal POR (output 23a) is applied to the counter 16. Consequently, when this signal goes to "1" at time t 0 , the number N in this counter 16 goes to +1.
- the decision logic 20 is connected to the divider 13 to receive a time signal establishing a predetermined duration DP which in the present example is chosen at 4 seconds.
- the generator 1 Despite the fact that during phase P FI , the generator 1 always rotates at a speed lower than the nominal speed, it will nevertheless rotate the hands relatively quickly with respect to the nominal speed of the exact time and as regards the seconds hand over a sufficient angle (typically several seconds at a time) so that the phenomenon is easily perceptible by the user of the timepiece and encourages the latter to perform the winding.
- FIG. 3 illustrates this process by two curves C and D, the curve C corresponding to the case where the critical value N is reached just at the expiration of the predetermined duration.
- Curve D shows the case where at the expiration of the predetermined duration DP, the counter 16 contains a value N 2 much greater than the critical value.
- the decision logic 20 thus controls the braking transistor 22 at the end of the duration DP, the generator 1 is braked, the voltage supplied to the circuit 11 drops sharply to the point that the latter stops working, the braking transistor 22 is again made non-conductive and the generator restarts again causing the second hand to jerky. This process can be repeated until either of the following two events has occurred.
- the first event is that the user manually wind the spring or start to wear the timepiece by imprinting movements on it.
- the number accumulated in the counter 16 will decrease, because generator 1 will quickly regain speed nominal and send pulses to counter 16 at the same rhythm as divider 13. This eventuality is shown in Figure 3 by curve E.
- the starting circuit 23 will react when the voltage supplied to the integrated circuit 11 crosses downwards the value of 0.7 volts, for example.
- the signal on terminal 23b goes to "1" and makes transistor 24 conductive.
- That -It is chosen at a value such that the current established in this shunt absorbs an amount of energy such that the barrel 5 can no longer drive the hands at a speed perceptible to the wearer of the timepiece.
- This very low speed regime is established throughout the pronounced braking phase P FP which lasts until the almost total exhaustion of the power reserve.
- the pronounced braking phase P FP although optional, is useful for giving the wearer of the timepiece total stop information (the rotation of the seconds hands is then too low to be perceptible by the wearer. Without this phase, the non-attentive wearer could have the impression that the part is still working, the hands still progressing at a speed, admittedly slow, but still perceptible to the wearer, especially during a certain time interval immediately following the intermittent braking phase P FI .
- the resistor 25 must be chosen at a value such that the shunt that it constitutes with the transistor 25 does not prevent restarting, when the carrier proceeds to reassemble the spring 5 from the phase of pronounced braking P FP .
- FIG. 4 illustrates a variant of the invention which can be added in addition to the assembly to completely prevent rotation of the generator 1 at the end of the pronounced braking phase P FP .
- This variant consists in placing in the vicinity of the periphery of the rotor 2 of the generator 1 one or more magnets 26 of very low attraction force and capable of imposing a low positioning torque on this rotor, a torque which, in order not to prevent restarting, must not be greater than the torque that the barrel will be able to provide when the power reserve is almost entirely used up.
- the rotor 2 shown in plan has magnets oriented perpendicular to the plane drawing. They are alternately North and South depending on the around the rotor. The magnets 26 are placed next to the rotor in the same orientation.
