DOMAINE TECHNIQUE TECHNICAL AREA
La présente invention concerne une montre électronique comprenant un ou des moteurs électriques pour entraîner des moyens d'affichage analogiques, un module horloger comprenant une base de temps fournissant un signal d'horloge connecté à un circuit diviseur, ledit circuit diviseur fournissant un signal de référence envoyé à un circuit de contrôle agencé pour contrôler le ou les moteurs électriques. The present invention relates to an electronic watch comprising one or more electric motors for driving analog display means, a watch module comprising a time base providing a clock signal connected to a divider circuit, said divider circuit providing a reference signal sent to a control circuit arranged to control the electric motor or motors.
ARRIERE-PLAN TECHNOLOGIQUE BACKGROUND
Il est connu dans l'art antérieur, visible à la figure 1 , une base de temps formée par un résonateur par exemple piézoélectrique, comme un résonateur à quartz 1 , ou encore un résonateur en silicium du type MEMS connecté aux bornes d'un oscillateur 2 dont la sortie est connectée à un circuit diviseur de fréquence 3 pour obtenir la fréquence de marche souhaitée pour la montre de manière à indiquer l'heure exacte. La sortie du circuit diviseur de fréquence 3 est connectée à un circuit de commande 4 d'un moteur électrique 5 permettant d'entraîner les rouages, non représentés ici, faisant tourner les moyens d'affichage analogiques, tels que des aiguilles servant à fournir l'indication de l'heure, i.e. heures, minutes et éventuellement secondes. Le résonateur, l'oscillateur, le circuit diviseur et le circuit de commande sont installés dans un même boîtier 6. It is known in the prior art, visible in FIG. 1, a time base formed by a resonator, for example a piezoelectric resonator, such as a quartz resonator 1, or a silicon resonator of the MEMS type connected to the terminals of an oscillator. 2 whose output is connected to a frequency divider circuit 3 to obtain the desired operating frequency for the watch so as to indicate the exact time. The output of the frequency divider circuit 3 is connected to a control circuit 4 of an electric motor 5 for driving the cogs, not shown here, rotating the analog display means, such as needles to provide the indication of the time, ie hours, minutes and possibly seconds. The resonator, the oscillator, the dividing circuit and the control circuit are installed in the same housing 6.
Néanmoins, cette configuration ne permet pas d'avoir un circuit indépendant des fluctuations de température puisqu'aucun circuit de compensation thermique n'est prévu. Il est connu des circuits horlogers compensés thermiquement. Ces circuits comprennent un module horloger relié à un quartz et également relié à un circuit de mesure de température et de correction. Ce circuit de mesure et de correction est ainsi agencé pour mesurer la température et pour corriger la marche du circuit horloger. However, this configuration does not allow a circuit independent of temperature fluctuations since no thermal compensation circuit is provided. There are known thermally compensated watch circuits. These circuits include a watch module connected to a quartz and also connected to a temperature measurement and correction circuit. This measurement and correction circuit is thus arranged to measure the temperature and to correct the march of the watch circuit.
Un inconvénient de ces circuits est qu'ils prennent de la place c'est à dire que leur surface est importante et que la calibration se fait au niveau des calibres montés. Cela entraîne une hausse du coût de fabrication de la correction de la dépendance en température sur les calibres. De plus, cette configuration est sensible à l'humidité pouvant s'infiltrer dans le boîtier de la pièce d'horlogerie. Cette sensibilité à l'humidité entraîne une dégradation de la précision et de la fiabilité du circuit horloger. A disadvantage of these circuits is that they take up space, that is to say that their surface is important and that the calibration is done at the calibres mounted. This leads to an increase in the manufacturing cost of the correction of the temperature dependence on the gauges. In addition, this configuration is sensitive to the moisture that can infiltrate the housing of the timepiece. This sensitivity to moisture leads to a degradation of the accuracy and reliability of the watch circuit.
Par ailleurs, pour un circuit horloger ayant une fonction chronographe, on ajoute l'inconvénient d'avoir un module supplémentaire et donc les mêmes problèmes de surfaces et de sensibilité à l'humidité. Furthermore, for a watch circuit having a chronograph function, the disadvantage of having an additional module and therefore the same surface problems and sensitivity to moisture.

DESCRIPTION DETAILLEE DE L'INVENTION DETAILED DESCRIPTION OF THE INVENTION
Conformément à un premier mode de réalisation de l'invention représenté schématiquement sur la figure 2, l'invention concerne une pièce d'horlogerie électronique comprenant circuit horloger 10 muni d'un module horloger 12. Ce module horloger 12 comprend une base de temps 14 formée par un résonateur 14a par exemple piézoélectrique, comme un résonateur à quartz, ou encore un résonateur en silicium du type MEMS connecté aux bornes d'un oscillateur 14b. Cet oscillateur 14b est utilisé pour fournir un signal d'horloge Sh à une fréquence d'horloge. Cette fréquence d'horloge est généralement de 32768 Hz appelé classiquement 32kHz. Dans le reste de la description, on comprendra que le terme 32kHz fait référence à cette valeur de 32768 Hz. According to a first embodiment of the invention shown schematically in Figure 2, the invention relates to an electronic timepiece comprising a watch circuit 10 provided with a watch module 12. This watch module 12 comprises a time base 14 formed by a resonator 14a for example piezoelectric, such as a quartz resonator, or a silicon resonator MEMS type connected across an oscillator 14b. This oscillator 14b is used to provide a clock signal Sh at a clock frequency. This clock frequency is typically 32768 Hz, typically called 32kHz. In the rest of the description, it will be understood that the term 32kHz refers to this value of 32768 Hz.
La sortie de l'oscillateur est connectée à un circuit diviseur de fréquence 16 pour obtenir la fréquence de marche souhaitée pour la montre de manière à indiquer l'heure exacte. Par exemple, le circuit diviseur 16 fournira en sortie une fréquence de 1 Hz pour que l'aiguille des secondes puisse se déplacer d'un pas par seconde. La sortie du circuit diviseur de fréquence 16 est connectée à un circuit de contrôle 18. Ce circuit de contrôle 18 est utilisé afin de gérer le module horloger 12 c'est-à-dire à régler la marche de la pièce d'horlogerie et à gérer des fonctions comme le mode batterie faible. On comprendra que le circuit de contrôle 18, la base de temps 14 et le circuit diviseur de fréquence 16 peuvent se présenter sous la forme du même composant. Le circuit horloger 10 est également muni d'un moteur électrique M1 permettant d'entraîner les rouages, non représentés ici, faisant tourner les moyens d'affichage analogiques, tels que des aiguilles 22 servant à fournir l'indication de l'heure, i.e. heures, minutes et éventuellement secondes. Le moteur électrique est connecté au circuit de contrôle 18 qui commande la marche dudit moteur électrique M1 . The output of the oscillator is connected to a frequency divider circuit 16 to obtain the desired operating frequency for the watch so as to indicate the exact time. For example, the divider circuit 16 will output a frequency of 1 Hz so that the second hand can move one step per second. The output of the frequency divider circuit 16 is connected to a control circuit 18. This control circuit 18 is used to manage the watch module 12, that is to say to adjust the time of the timepiece and manage functions such as low battery mode. It will be understood that the control circuit 18, the time base 14 and the frequency divider circuit 16 may be in the form of the same component. The watch circuit 10 is also provided with an electric motor M1 for driving the gear trains, not shown here, rotating the analog display means, such as needles 22 serving to provide the time indication, ie hours, minutes and possibly seconds. The electric motor is connected to the control circuit 18 which controls the operation of said electric motor M1.
Avantageusement selon l'invention, le circuit de contrôle 18, la base de temps 14 et le circuit diviseur de fréquence 16 sont agencés dans le même boîtier 13 et le circuit horloger comprend en outre un circuit de mesure et de correction 26 permettant une thermo-compensation. Ce circuit de mesure et de correction 26 est placé entre le circuit oscillateur 14b et le circuit diviseur de fréquence 16. Ce circuit de mesure et de correction 26 est utilisé pour compenser thermiquement le module horloger 12 c'est-à-dire qu'en fonction de la température, il va agir sur le signal sortant de l'oscillateur 14b c'est-à-dire le signal d'horloge Sh. Le circuit de mesure et de correction 26 agit de sorte que le signal sortant dudit circuit de mesure et de correction 26 soit précis en moyenne sur une période définie. Pour cela, le circuit de mesure et de correction 26 inhibe des impulsions sur le signal d'horloge Sh. De ce fait, l'ensemble formé de la base de temps 14 et du circuit de mesure et de correction 26 fournit un signal Si dont la fréquence est plus faible que la fréquence du signal d'horloge Sh. Cela est dû au fait que le circuit de mesure et de correction 26 inhibe des impulsions c'est à dire qu'il supprime des impulsions. Par exemple, pour un signal d'horloge de 32 kHz, un signal de fréquence 8192Hz appelé classiquement 8 kHz thermo compensé c'est-à-dire précis et fiable sera fourni par cet ensemble formé de la base de temps 14 et du circuit de mesure et de correction 26. Pour améliorer la fiabilité du module horloger 12, le boîtier 13 dans lequel il est agencé est en céramique et est scellé hermétiquement avant calibration. Le boîtier 13 est mis sous vide puis fermé. Cela assure que l'humidité ne pourra pas s'infiltrer dans ledit boîtier 13. Par conséquent, l'humidité n'aura pas d'influence sur la précision du module horloger 12 Advantageously according to the invention, the control circuit 18, the time base 14 and the frequency divider circuit 16 are arranged in the same housing 13, and the clock circuit further comprises a measurement and correction circuit 26 enabling a thermistor compensation. This measurement and correction circuit 26 is placed between the oscillator circuit 14b and the frequency divider circuit 16. This measurement and correction circuit 26 is used to thermally compensate the watch module 12, that is to say that depending on the temperature, it will act on the signal coming out of the oscillator 14b, that is to say the clock signal Sh. The measurement and correction circuit 26 acts in such a way that the signal coming out of said measuring circuit and correction 26 is accurate on average over a defined period. For this, the measuring and correction circuit 26 inhibits pulses on the clock signal Sh. Therefore, the assembly formed of the time base 14 and the measurement and correction circuit 26 provides a signal Si whose the frequency is lower than the frequency of the clock signal Sh. This is due to the fact that the measurement and correction circuit 26 inhibits pulses, that is to say that it suppresses pulses. For example, for a clock signal of 32 kHz, a signal 8192Hz frequency conventionally called 8 kHz thermo compensated that is to say accurate and reliable will be provided by this set formed the time base 14 and the circuit of measurement and correction 26. To improve the reliability of the watch module 12, the housing 13 in which it is arranged is ceramic and is sealed before calibration. The housing 13 is evacuated and closed. This ensures that the moisture can not infiltrate into said housing 13. Therefore, the humidity will have no influence on the accuracy of the watch module 12
En effet, un aspect de l'invention consiste à fourni un procédé de calibration permettant d'obtenir un circuit horloger 10 fiable dans la durée. Indeed, one aspect of the invention is to provide a calibration method for obtaining a reliable watch circuit 10 over time.
Pour cela, le procédé consiste à assembler le circuit de contrôle 18, la base de temps 14, le circuit diviseur de fréquence 16 et le circuit de mesure et de correction 26 dans le même boîtier 13 afin de former le module horloger 12. Puis, la calibration se fait en batch c'est-à-dire en parallèle. On comprend alors qu'une pluralité de modules horlogers 12 sont calibrés en même temps. Cette calibration consiste alors à mesurer les caractéristiques du résonateur 14a ainsi que du circuit de mesure 26 en fonction de la température puis à déterminer des paramètres de correction. For this, the method consists in assembling the control circuit 18, the time base 14, the frequency divider circuit 16 and the measurement and correction circuit 26 in the same housing 13 in order to form the watch module 12. Then, the calibration is done in batch that is to say in parallel. It is then understood that a plurality of watch modules 12 are calibrated at the same time. This calibration then consists in measuring the characteristics of the resonator 14a as well as the measuring circuit 26 as a function of the temperature, and then in determining the correction parameters.
Ces paramètres de correction sont mémorisés dans le circuit de mesure et de correction 26. Ainsi, les paramètres de correction de chaque résonateur 14a d'une pluralité de modules horlogers 12 sont déterminés simultanément. Ce procédé présente alors l'avantage de permettre la calibration d'un grand nombre de module horloger 12 de façon simultanée et donc de réduire les coûts associés à cette calibration. These correction parameters are stored in the measurement and correction circuit 26. Thus, the correction parameters of each resonator 14a of a plurality of watch modules 12 are determined simultaneously. This method then has the advantage of allowing the calibration of a large number of watch module 12 simultaneously and thus reduce the costs associated with this calibration.
Avantageusement selon l'invention, cette configuration permet de réaliser simplement un module horloger chronographe 30 thermo-compensé comme visible à la figure 3. Advantageously according to the invention, this configuration makes it possible to simply produce a thermo-compensated chronograph chronograph module 30 as can be seen in FIG.
En effet, la présente invention prévoit d'utiliser le signal d'horloge du module horloger 12 pour cadencer un module chronographe 30. Ce module chronographe 30 comprend un circuit de contrôle et des circuits permettant de faire fonctionner les aiguilles de la fonction chronographe. Par exemple, le circuit de contrôle du module chronographe 30 est agencé pour faire fonctionner deux moteurs M2 et M3. Dans ce cas-là, il est envisageable qu'il n'y ait pas de moteur M1 connecté au module horloger 12. Indeed, the present invention provides to use the clock signal of the watch module 12 to clock a chronograph module 30. This chronograph module 30 comprises a control circuit and circuits for operating the hands of the chronograph function. For example, the control circuit of the chronograph module 30 is arranged to operate two motors M2 and M3. In this case, it is conceivable that there is no motor M1 connected to the watch module 12.
Préférentiellement, le module chronographe 30 est cadencé avec le signal thermo-compensé c'est-à-dire le signal Si sortant du circuit de mesure et de correction 26 du module horloger 12. Dans l'exemple cité auparavant, pour un signal d'horloge Sh ayant une fréquence de 32 kHz, on obtient un signal Si thermo-compensé de fréquence 8 kHz. Preferably, the chronograph module 30 is clocked with the thermo-compensated signal, that is to say the signal S0 coming out of the measurement and correction circuit 26 of the watch module 12. In the example cited above, for a signal of clock Sh having a frequency of 32 kHz, a heat-compensated Si signal of frequency 8 kHz is obtained.
De ce fait, le module chronographe 30 est un module qui ne possède pas sa propre base de temps ce qui réduit son coût. As a result, the chronograph module 30 is a module that does not have its own time base which reduces its cost.
Ce signal thermo-compensé Si fournit par le module horloger 12 est utilisé pour reconstruire des signaux utiles pour le module chronographe 30. Par exemple, le signal thermo-compensé peut être utilisé pour reconstruire un signal à plus forte fréquence pour cadencer un circuit de contrôle du module chronographe. De ce fait, le circuit de contrôle du module chronographe peut faire fonctionner les moteurs M2, M3 associés à cette fonction chronographe. This thermo-compensated signal Si supplied by the watch module 12 is used to reconstruct useful signals for the chronograph module 30. For example, the thermo-compensated signal can be used to reconstruct a higher frequency signal to clock a control circuit. Chronograph module. As a result, the control circuit of the chronograph module can operate the motors M2, M3 associated with this chronograph function.
Le signal de fréquence plus élevée reconstruit peut être utilisé pour une fonction de détermination de la position des rouages. Cette possibilité de cadencer un module chronographe 30 avec un signal thermo-compensé d'un module horloger présente des avantages. The reconstructed higher frequency signal can be used for a function of determining the position of the wheels. This ability to clock a chronograph module 30 with a thermo-compensated signal of a watch module has advantages.
Premièrement, elle permet de réaliser un module horloger chronographe thermo-compensé simple. En effet, les modules horlogers chronographes connus utilisent directement le signal en sortie du résonateur à 32KHz pour fonctionner. Or, en utilisant le signal directement en sortie du résonateur, ce dernier ne peut pas être thermo-compensé. De ce fait, le fonctionnement du module horloger chronographe devient aléatoire. De même, en utilisant un signal thermo-compensé existant, on évite de devoir réaliser un module chronographe 30 comprenant sa propre base de temps et son propre circuit de mesure et de correction. First, it allows for a simple thermo-compensated chronograph watch module. In fact, the known chronograph watch modules use the signal directly at the output of the resonator at 32KHz to operate. However, by using the signal directly at the output of the resonator, it can not be thermo-compensated. As a result, the operation of the chronograph watch module becomes random. Similarly, by using an existing thermo-compensated signal, avoids having to make a chronograph module 30 including its own time base and its own measurement and correction circuit.
Au contraire, avec la présente invention, on arrive à obtenir un circuit horloger 10 avec une fonction chronographe entièrement thermo-compensé et à moindre coût. Effectivement, la présente invention utilise le seul module horloger 12 et son signal Si thermo-compensé de fréquence 8kHz pour thermo-compenser le module chronographe 30 en faisant en sorte que le signal thermo-compensé soit utilisé par ledit module chronographe. De ce fait, il est aisé de passer d'un module horloger à un module horloger chronographe. On the contrary, with the present invention, it is possible to obtain a watch circuit 10 with a fully thermo-compensated chronograph function and at a lower cost. Indeed, the present invention uses the only watch module 12 and its thermo-compensated signal Si frequency 8kHz to thermo-compensate the chronograph module 30 by ensuring that the thermo-compensated signal is used by said chronograph module. As a result, it is easy to move from a watch module to a chronograph watch module.
De plus, cette configuration permet d'avoir un module horloger chronographe plus économe en énergie électrique. En effet, le module chronographe utilise un signal d'horloge thermo-compensé d'une fréquence moindre que la fréquence de la base de temps 14. Or, plus la fréquence est élevée et plus les pertes liées aux capacités d'interconnexion sont importantes. En effet, le transport d'un signal d'une certaine fréquence sur un circuit imprimé est soumis aux effets capacitifs, inductifs et aux effets de peau qui peuvent avoir lieu. Ces effets sont tous liés à la fréquence impliquant une augmentation des pertes liées à ces effets en fonction de la fréquence. Par conséquent, pour compenser les pertes, il faut fournir une puissance électrique plus importante. In addition, this configuration makes it possible to have a chronograph chronograph module that is more economical in electrical energy. Indeed, the chronograph module uses a thermo-compensated clock signal of a frequency less than the frequency of the time base 14. However, the higher the frequency, the greater the losses related to the interconnection capacity. Indeed, the transport of a signal of a certain frequency on a printed circuit is subject to the capacitive, inductive and skin effects that can take place. These effects are all frequency-related, implying an increase in frequency-related losses due to these effects. Therefore, to compensate for the losses, it is necessary to provide a larger electrical power.
Avec la configuration selon l'invention, on utilise une fréquence plus faible pour cadencer le module chronographe et donc les pertes liées à une surconsommation sont moindres. On comprendra que diverses modifications et/ou améliorations et/ou combinaisons évidentes pour l'homme du métier peuvent être apportées aux différents modes de réalisation de l'invention exposée ci-dessus sans sortir du cadre de l'invention définie par les revendications annexées. With the configuration according to the invention, a lower frequency is used to clock the chronograph module and therefore the losses associated with overconsumption are lower. It will be understood that various modifications and / or improvements and / or combinations obvious to those skilled in the art can be made to the various embodiments of the invention set out above without departing from the scope of the invention defined by the appended claims.
