Description

Dispositif de transmission de puissance inductif  Inductive power transmission device
La présente invention concerne un module de transmission de puissance combiné à un module de communication à champ proche. The present invention relates to a power transmission module combined with a near field communication module.
Il est connu d'utiliser des modules de transmission de puissance pour alimenter ou charger la batterie de dispositifs nomades tel que par exemple des téléphones portables. Devant la multiplication des modèles de nomades, l'utilisation de dispositif de charge sans fil utilisant le transfert de puissance par un moyen inductif présente l'avantage de pouvoir s'affranchir de l'utilisation de chargeurs spécifiques à chaque modèle de nomade. De tel transmetteurs de puissance inductif sans fil sont connus pour des utilisations aussi bien au sein de bâtiments tel que par exemple des domiciles de particuliers que pour des utilisations utilisés dans des habitacles de véhicule automobile. It is known to use power transmission modules to power or charge the battery of nomadic devices such as for example mobile phones. In view of the multiplication of nomadic models, the use of a wireless charging device using power transfer by inductive means has the advantage of being able to overcome the use of chargers specific to each nomad model. Such wireless inductive power transmitters are known for uses both within buildings such as for example private homes and for uses used in motor vehicle interiors.
La figure 1 présente le fonctionnement d'un tel module de transmission de puissance 100 monté dans un socle 102 et coopérant avec un nomade 200, ici un téléphone portable. Le module de transmission de puissance 100 comporte une bobine d'émission 110 et le nomade 200 comporte une bobine de réception 210. Pour transmettre de la puissance vers le nomade 200, on fait passer un courant alternatif dans la bobine d'émission 110 afin de produire un champ magnétique 101. Ce champ magnétique 101 traverse la bobine 210 du nomade et produit une tension au sein de ladite bobine. La tension ainsi produite peut dès lors être utilisée pour alimenter le nomade ou encore charger la batterie de ce dernier. Figure 1 shows the operation of such a power transmission module 100 mounted in a base 102 and cooperating with a nomad 200, here a mobile phone. The power transmission module 100 comprises a transmission coil 110 and the nomad 200 comprises a reception coil 210. To transmit power to the nomad 200, an alternating current is passed through the transmission coil 110 in order to produce a magnetic field 101. This magnetic field 101 passes through the coil 210 nomad and produces a voltage within said coil. The voltage thus produced can then be used to power the nomad or charge the battery of the latter.
Pour économiser l'énergie, le champ magnétique 101 ne doit pas être émis en permanence car, devant la puissance à émettre, la demande en courant est assez élevée. C'est pourquoi un tel transmetteur de puissance est configuré pour produire un champ magnétique uniquement lorsque les deux bobines 110 et 210 sont placées l'une en regard de l'autre. A cet effet, les modules de transmission de puissance et nomade possèdent chacun respectivement des dispositifs de communication 120 et 220 permettant aux deux dispositifs de communiquer entre eux. Ces dispositifs de communication 120 et 220 comprennent chacun un dispositif d'émission et un dispositif de réception. Ces dispositifs d'émission et réception comprennent ici à titre d'exemple des circuit de modulation et de démodulation de fréquence ou d'amplitude de signaux de communication destinés à transiter sur la porteuse crée par le champ magnétique 101. Le principe de base consiste à émettre le champ magnétique 101 uniquement lorsque la présence d'un nomade a été détectée sur le socle 102 du module de transmission de puissance. Pour opérer cette détection, le dispositif de communication 120 du module de transmission de puissance émet selon une période fixe prédéterminée un signal de scrutation « ping » vers l'emplacement réservé sur le socle 102 au nomade. Tout pendant qu'aucun nomade n'est présent le socle, le récepteur 120 du transmetteur de puissance ne détecte aucun signal de retour et n'envoie pas de puissance. Dans ce cas, la porteuse 101 qui porte les signaux modulés de communication est de faible puissance, à savoir d'une puissance bien inférieure à celle nécessaire pour alimenter ou charger la batterie d'un nomade tel que par exemple un téléphone portable. Dès que l'on place un nomade sur le socle 102 et que les deux bobines 120, 220 se trouvent en regard l'une de l'autre, la puissance transmise par le champ magnétique 101 réveille le dispositif de contrôle de charge 230 du nomade qui, en réponse à la réception au signal de scrutation « ping », envoie vers le module de transmission de puissance un signal de présence du nomade. A titre d'exemple, ce signal de présence peut consister en un identifiant stocké de manière permanente dans le nomade et qui est représentatif du nomade détecté. Dès que ce signal de présence est détecté par le module de transmission de puissance 100, ce dernier génère un champ magnétique 101 adapté au nomade détecté grâce au dispositif de contrôle de charge 130 du module de transmission de puissance qui adapte la puissance du champ magnétique en fonction de l'identifiant reçu. Tout pendant que la transmission de puissance est effectuée, le module de transmission de puissance et le nomade communiquent entre eux pour bien vérifier que le nomade est toujours présent sur le socle 102 du transmetteur de puissance. Ainsi, le dispositif de communication 120 envoie de façon périodique un signal de scrutation « ping », et le nomade répond présent par l'envoi d'un message en retour, ici l'identifiant à titre d'exemple. Dès que l'on retire le nomade, le signal de retour ne parvient plus au module de transmission de puissance et l'on fait décroître la puissance du champ magnétique 101 de sorte qu'elle soit juste nécessaire pour servir de porteuse aux signaux de communication modulés, notamment le signal de scrutation « ping ». Le nomade peut également envoyer un signal représentatif de la fin de charge de sa batterie vers le transmetteur de puissance et comme dans le cas du retrait du nomade, le dispositif de contrôle de charge 130 fait décroître la puissance du champ magnétique 101 pour la limiter à son rôle de porteuse pour les signaux modulés. To save energy, the magnetic field 101 must not be emitted permanently because, in front of the power to be emitted, the current demand is quite high. This is why such a power transmitter is configured to produce a magnetic field only when the two coils 110 and 210 are placed facing each other. For this purpose, the power and nomad transmission modules each have communication devices 120 and 220, respectively, enabling the two devices to communicate with one another. These communication devices 120 and 220 each comprise a transmission device and a device reception. These transmission and reception devices here comprise, by way of example, modulation and demodulation circuits of frequency or amplitude of communication signals intended to transit on the carrier created by the magnetic field 101. The basic principle consists of to emit the magnetic field 101 only when the presence of a nomad has been detected on the base 102 of the power transmission module. In order to effect this detection, the communication device 120 of the power transmission module transmits, according to a predetermined fixed period, a scanning signal "ping" to the reserved location on the base 102 at the nomad. While no nomad is present the base, the receiver 120 of the power transmitter detects no return signal and does not send power. In this case, the carrier 101 which carries the modulated communication signals is of low power, namely a much lower power than that necessary to supply or charge the battery of a nomad such as for example a mobile phone. As soon as a nomad is placed on the base 102 and the two coils 120, 220 are facing each other, the power transmitted by the magnetic field 101 awakens the load control device 230 of the nomad which, in response to the reception at the "ping" scanning signal, sends to the power transmission module a presence signal of the nomad. By way of example, this presence signal may consist of an identifier stored permanently in the nomad and which is representative of the nomad detected. As soon as this presence signal is detected by the power transmission module 100, the latter generates a magnetic field 101 adapted to the nomad detected by the load control device 130 of the power transmission module which adjusts the power of the magnetic field. function of the received identifier. While the power transmission is performed, the power transmission module and the nomad communicate with each other to verify that the nomad is still present on the base 102 of the power transmitter. Thus, the communication device 120 periodically sends a polling signal "ping", and the nomad responds present by sending a message back, here the identifier by way of example. As soon as the nomad is removed, the return signal no longer reaches the power transmission module and the power of the magnetic field 101 is decreased so that it is only necessary to serve as a carrier for the communication signals. modulated, in particular the "ping" scanning signal. The nomad can also send a signal representative of the end of charging of the battery to the power transmitter and as in the case of the removal of the nomad, the load control device 130 decreases the power of the magnetic field 101 to limit its role as a carrier for the modulated signals.
Comme on peut le voir, un tel module de transmission de puissance est entièrement autonome et se suffit à lui-même. Il n'est pas nécessaire de réaliser des interventions extérieures pour la mise en route de la transmission de puissance et la communication se fait de manière transparente pour l'utilisateur quelque soit l'environnement où est placé ce module de transmission de puissance ; qu'il soit placé dans une maison ou un véhicule automobile, son fonctionnement demeure identique. As can be seen, such a power transmission module is entirely autonomous and self-sufficient. It is not necessary to perform external interventions for the start of power transmission and the communication is done transparently for the user regardless of the environment where the power transmission module is placed; whether it is placed in a house or a motor vehicle, its operation remains the same.
D'autre part il aussi est connu d'utiliser des lecteurs de communication en champ proche pour échanger des informations avec un autre dispositif séparés par une distance n'excédant pas une dizaine de centimètres. Un exemple de ce type de communication est connu sous le terme NFC (Near Field Communication). Ce type de communication rapprochée, limité aux très courtes distances est utilisé par exemple dans des applications dédiées aux transports. Ainsi, on équipe des cartes ou des badges de transport de dispositifs NFC que les usagers passent devant des lecteurs dédiés afin de pouvoir accéder aux quais. Ces dispositifs qui équipent les nomades tels que des badges, des cartes d'accès ou des téléphones mobiles sont appelés « tag ». Ils sont composés d'une antenne de réception-émission et d'un circuit logique de contrôle du tag qui peut également une zone de stockage d'informations destinées à être échangées avec un lecteur de tag. Le fait que la portée de la communication soit limitée à une très courte distance présente l'avantage qu'un lecteur de badge NFC ne peut reconnaître que les badges qui sont volontairement placé devant la zone de lecture prévue à cet effet. Il ne peut donc pas y avoir de lecture non désirée d'un badge par exemple porté par une autre personne se trouvant à une distance trop éloignée du lecteur de badge. C'est un dispositif de sécurité basé sur la communication à très courte distance. On the other hand it is also known to use near-field communication readers to exchange information with another device separated by a distance of not more than ten centimeters. An example of this type of communication is known as NFC (Near Field Communication). This type of close communication, limited to very short distances is used for example in applications dedicated to transport. Thus, we equip NFC devices cards or badges that users pass in front of dedicated readers in order to access the platforms. These devices that equip nomads such as badges, access cards or mobile phones are called "tag". They are composed of a reception-transmission antenna and a tag control logic circuit which can also an information storage area intended to be exchanged with a tag reader. The fact that the range of communication is limited to a very short distance has the advantage that an NFC badge reader can recognize only the badges that are deliberately placed in front of the reading zone provided for this purpose. There can therefore be no unwanted reading of a badge for example worn by another person at a distance too far from the badge reader. It is a security device based on very short distance communication.
De tels dispositifs de communication en champ proche (appelés NFC ci-après) sont déjà connus pour des applications téléphoniques dans lesquelles on place par exemple des tags NFC sur téléphones nomades afin de réaliser par exemple des transactions commerciales. Such near-field communication devices (hereinafter referred to as NFC) are already known for telephone applications in which, for example, NFC tags on mobile phones in order to carry out, for example, commercial transactions.
La figure 2 présente le fonctionnement d'un tel lecteur de tag NFC 300 comportant un socle 302 et coopérant avec un nomade 400 équipé d'un module de d'émission- réception NFC constitué par exemple d'un Tag NFC. FIG. 2 shows the operation of such an NFC tag reader 300 comprising a base 302 and cooperating with a nomad 400 equipped with an NFC transmission / reception module consisting for example of an NFC tag.
Le lecteur de tag 300 comporte une bobine d'émission réception 310 et le nomade 400 comporte une bobine de émission réception 410 par exemple placée à l'intérieur du nomade sous la forme d'un tag. Un tag se présente généralement sous la forme d'un étiquette qui possède une antenne et un circuit logique. En variante, le tag peut être remplacé par un circuit de contrôle du nomade qui simule le fonctionnement d'un tag. Dans ce cas, le tag ainsi simulé peut coopérer avec d'autres fonctionnalités du nomade tel que par exemple un téléphone portable. The tag reader 300 comprises a transmitting coil 310 and the nomad 400 comprises a transmitting coil 410 for example placed inside the nomad in the form of a tag. A tag is generally in the form of a tag that has an antenna and a logic circuit. Alternatively, the tag may be replaced by a nomadic control circuit that simulates the operation of a tag. In this case, the tag thus simulated can cooperate with other features of the nomad such as for example a mobile phone.
Pour transmettre un message vers le nomade 400, on fait passer un courant dans la bobine d'émission réception 310 du lecteur de tag 300 afin de produire un champ magnétique 301. Ce champ magnétique 301 traverse la bobine 410 du tag du nomade et produit une tension au sein de ladite bobine 410. Ce champ doit être suffisamment puissant pour alimenter le circuit du tag. To transmit a message to the nomad 400, a current is passed through the transmitting coil 310 of the tag reader 300 to produce a magnetic field 301. This magnetic field 301 passes through the coil 410 of the nomad tag and produces a voltage within said coil 410. This field must be powerful enough to power the tag circuit.
Les lecteurs de tag et nomade possèdent chacun respectivement des dispositifs de communication 320 et 420 permettant aux deux dispositifs de communiquer entre eux. Ces dispositifs de communication 320 et 420 comprennent chacun un dispositif d'émission et un dispositif de réception. Ces dispositifs d'émission et réception comprennent ici à titre d'exemple des circuit de modulation et de démodulation de fréquence ou d'amplitude de signaux de communication destinés à transiter sur la porteuse crée par le champ magnétique 301. The tag and nomad readers each have respective communication devices 320 and 420 allowing the two devices to communicate with each other. These communication devices 320 and 420 each comprise a transmitting device and a receiving device. These transmission and reception devices here comprise, by way of example, modulation and demodulation circuits of frequency or amplitude of communication signals intended to pass on the carrier created by the magnetic field 301.
Le dispositif de communication 320 du lecteur de tag 300 émet selon une période fixe prédéterminée un signal de scrutation « ping » dans une zone de lecture située aux environs du socle 301. Tant qu'aucun nomade ne se trouve à la distance minimale pour l'établissement d'une communication NFC, le récepteur du circuit de communication 320 du lecteur de tag 300 ne détecte aucun signal de retour. Dès que l'on place un nomade à l'intérieur de la zone de communication, la puissance transmise par le champ magnétique 301 réveille le dispositif de contrôle du tag 430 du nomade qui, en réponse à la réception au signal de scrutation « ping », envoie vers le lecteur de tag 300 un signal de présence du nomade. A titre d'exemple, ce signal de présence peut consister en un identifiant stocké dans une NVRAM (Non Volatile Ram) intégrée par exemple dans le composant électronique du Tag NFC du nomade. The communication device 320 of the tag reader 300 transmits, according to a predetermined fixed period, a "ping" polling signal in a reading zone situated around the base 301. As long as no nomad is at the minimum distance for the establishing an NFC communication, the receiver of the communication circuit 320 of the tag reader 300 detects no return signal. As soon as a nomad is placed inside the communication zone, the power transmitted by the magnetic field 301 wakes up the control device of the tag 430 of the nomad which, in response to the reception, at the polling signal "ping" sends to the tag reader 300 a presence signal of the nomad. By way of example, this presence signal may consist of an identifier stored in a NVRAM (Non Volatile Ram) integrated for example in the electronic component of the NFC tag of the nomad.
Contrairement à la communication Bluetooth ® qui s'effectue avec des distances plus élevées entre le nomade et le lecteur, la communication NFC s'effectue à des distances rapprochées. Pour cette raison il peut s'avérer utile pour indiquer la présence du tag dans une zone proche du lecteur de Tag. Unlike Bluetooth ® communication with higher distances between the nomad and the reader, NFC communication takes place at close distances. For this reason it may be useful to indicate the presence of the tag in an area close to the tag reader.
Toutefois, bien q'ayant des finalités différentes - transmission de puissance pour le premier, échange de données pour le second - ces deux dispositifs présentent des similitudes de fonctionnement importantes. However, although having different purposes - power transmission for the first, data exchange for the second - these two devices have significant operating similarities.
En particulier pour le premier, afin d'assurer une bonne efficacité de la transmission de puissance entre le module émetteur 100 du chargeur par induction et le nomade récepteur 200 il est nécessaire d'avoir un bon couplage physique des bobines de l'émetteur 110 et du récepteur 210. C'est-à-dire qu'en pratique il faut que la distance entre les deux bobines soit inférieure à 5 mm. In particular for the former, in order to ensure a good efficiency of power transmission between the transmitter module 100 of the induction charger and the receiver nomad 200 it is necessary to have a good physical coupling of the coils of the transmitter 110 and of the receiver 210. That is to say that in practice it is necessary that the distance between the two coils is less than 5 mm.
Ceci entraîne une contrainte pour l'utilisateur qui doit s'assurer du bon positionnement du nomade 200 sur le socle 102 de l'émetteur de puissance 100. This entails a constraint for the user who must ensure the proper positioning of the nomad 200 on the base 102 of the power transmitter 100.
De même pour le second, pour assurer un bon échange des données entre le dispositif de communication à champ proche (NFC) et l'équipement nomade il est nécessaire, là encore, d'assurer un bon couplage entre la bobine (ou antenne) 310 du lecteur NFC et la bobine (ou antenne) 410 du nomade. Similarly for the second, to ensure a good exchange of data between the near field communication device (NFC) and the nomadic equipment it is necessary, here again, to ensure good coupling between the coil (or antenna) 310 the NFC reader and the nomad coil (or antenna) 410.
Cela impose de positionner l'équipement nomade sur le socle 102 du dispositif de charge inductif (fig. 1) ou le socle 302 du dispositif de communication à champ proche (fig. 2) correspondant à la fonction que l'on veut mettre en œuvre. This requires positioning the nomadic equipment on the base 102 of the inductive charging device (FIG 1) or the base 302 of the near-field communication device (Fig. 2) corresponding to the function that we want to implement.
Un but de l'invention est de permettre l'utilisation de ces deux dispositifs avec un seul nomade en même temps que l'utilisateur ait besoin de changer la position du nomade. An object of the invention is to allow the use of these two devices with a single nomad at the same time that the user needs to change the position of the nomad.
Cela est réalisé en combinant dans le même équipement l'ensemble des dispositifs permettant d'assurer les fonction de transmission de puissance et de communication de données en champ proche. C'est-à-dire, comme il est montré à la figure 3, en intégrant dans un même équipement 500, sous un même socle 502 destiné à accueillir l'équipement nomade les éléments suivants : This is achieved by combining in the same equipment all the devices to ensure the power transmission function and data communication in the near field. That is to say, as shown in FIG. 3, by integrating into the same equipment 500, under the same base 502 intended to accommodate the nomadic equipment the following elements:
- une bobine de transmission de puissance (110)  a power transmission coil (110)
- un premier dispositif de communication (120) entre le module de transmission de puissance et le nomade  a first communication device (120) between the power transmission module and the nomad
- un dispositif de contrôle (130) de la charge du nomade.  a control device (130) for nomadic charge.
- une bobine de transmission de données (310).  a data transmission coil (310).
- un deuxième dispositif de communication (320) entre le module de transmission de données et le nomade.  a second communication device (320) between the data transmission module and the nomad.
- un dispositif de contrôle (330) des échanges d'information avec le nomade. Cette caractéristique trouve un intérêt tout particulier dans le domaine de l'automobile où la sécurité des usagers rend nécessaire d'éviter les manipulations d'un appareil nomade pendant la conduite du véhicule.  a control device (330) for exchanging information with the nomad. This feature is of particular interest in the automotive field where the safety of users makes it necessary to avoid the manipulation of a nomadic device while driving the vehicle.
Cette caractéristique permettra aussi de gagner de la place dans le véhicule et de contribuer à l'amélioration de l'habitabilité dans le véhicule sans sacrifier les fonctions mises à la disposition des usagers.  This feature will also save space in the vehicle and contribute to improving the livability in the vehicle without sacrificing the functions available to users.
Enfin cette caractéristique permet de réduire le poids et donc contribuer à la réduction de consommation de carburant  Finally, this feature reduces weight and therefore contributes to the reduction of fuel consumption
De la même manière, on trouvera un intérêt dans l'habitât pour éviter les va et vient des équipements nomades entre plusieurs stations. Cela permettra en outre de réduire les besoins de câblage en limitant le nombre de prises de courant nécessaires pour alimenter les équipements chargeur inductif 100 et lecteur de communication à courte portée 300 (NFC). Un autre avantage de cette combinaison est de réduire la consommation de veille par la réduction du nombre d'équipements en veille, un seul équipement au lieu de deux équipements nécessitant une alimentation permanente dite de veille. Quoique généralement minime, cette consommation de veille peut ne plus être négligeable si on la considère sur une longue période comme une année car elle est permanente. Il n'est pas rare que cette consommation de veille dépasse en moyenne sur une année la consommation utile de l'équipement considéré. L'invention a pour objet un équipement comportant au moins In the same way, one will find an interest in the dwelling to avoid the comings and goings of nomadic equipments between several stations. This will further reduce the need for cabling by limiting the number of outlets needed to power the Inductive Charger 100 and Short Range Communication Reader 300 (NFC) equipment. Another advantage of this combination is to reduce the standby consumption by reducing the number of equipment in standby, a single equipment instead of two equipment requiring a so-called standby power supply. Although generally minimal, this standby consumption may not be negligible if it is considered over a long period as a year because it is permanent. It is not uncommon for this standby consumption to exceed on average by one year the useful consumption of the equipment in question. The subject of the invention is an equipment comprising at least

Les numéros identiques des différentes figures désignent les mêmes caractéristiques techniques. La figure 1 précédemment décrite montre un transmetteur inductif de puissance 100 comportant un premier moyen de communication lui permettant de communiquer vers l'extérieur, à savoir, vers le nomade 200 pour lequel il doit transmettre la puissance. Ces premiers moyens de communication comportent la bobine 110 qui fournit la porteuse aux signaux modulés par la logique de contrôle 130 et des moyens de modulations 120 aptes à moduler et démoduler des signaux échangés avec le nomade 200.

L'énergie à transmettre au nomade est fournie dans cet exemple par une source extérieure par une liaison 105. Other features and advantages of the invention will emerge from the description following, given by way of example, without limitation, with reference to the accompanying drawings in which: Figure 1 schematically shows an inductive power transmitter according to the prior art Figure 2 schematically shows a reader of a badge to Near-field communication (NFC) according to the prior art.

The identical numbers of the different figures designate the same technical characteristics. FIG. 1 previously described shows an inductive power transmitter 100 comprising a first communication means enabling it to communicate to the outside, namely to the nomad 200 for which it must transmit the power. These first communication means comprise the coil 110 which supplies the carrier to the signals modulated by the control logic 130 and modulation means 120 able to modulate and demodulate signals exchanged with the nomad 200. The coil 110 is placed near the base 102 which makes it possible to receive the nomad in order to ensure good coupling with the nomad coil and to limit the losses of the magnetic field 101. The energy to be transmitted to the nomad is provided in this example by an external source by a link 105 .
La figure 2 précédemment décrite montre un lecteur de badge à communication à champ proche (NFC) 300 comportant un premier moyen de communication lui permettant de communiquer vers l'extérieur, à savoir, vers le nomade 400 avec lequel il échange des informations. Ces premiers moyens de communication comportent la bobine 310 qui fournit la porteuse aux signaux modulés par la logique de contrôle 330 et des moyens de modulations 320 aptes à moduler et démoduler des signaux échangés avec le nomade 400. La bobine (ou antenne) 310 est placée prés du socle 302 qui permet d'accueillir le nomade affin d'assurer un bon couplage avec la bobine ou antenne 410 du nomade et de limiter les pertes du champ magnétique 301. FIG. 2 previously described shows a near field communication (NFC) card reader 300 comprising a first communication means enabling it to communicate to the outside, namely, to the nomad 400 with which it exchanges information. These first communication means comprise the coil 310 which supplies the carrier to the signals modulated by the control logic 330 and modulating means 320 capable of modulating and demodulating signals exchanged with the nomad 400. The coil (or antenna) 310 is placed near the base 302 which can accommodate the nomad affin to ensure a good coupling with the coil or antenna 410 nomad and limit losses of the magnetic field 301.
Selon un premier exemple de réalisation représente à la figure 3, l'équipement 500 comprend sous un socle 502 destiné à accueillir un équipement nomade 600 : une bobine de transmission de puissance 110 destiné à la charge dudit nomade 600, juxtaposée à une bobine (ou antenne) 310 de communication de données avec ledit nomade 600. According to a first exemplary embodiment shown in FIG. 3, the equipment 500 comprises under a base 502 intended to accommodate a nomadic equipment 600: a power transmission coil 110 intended to charge said nomad 600, juxtaposed with a coil (or antenna) 310 for communicating data with said nomad 600.
Le champ magnétique 101 produit par la bobine de transmission de puissance 110 est contrôlé par un module de communication 120 chargé de moduler ledit champ 101 en fonction du module de contrôle de charge 130. Dans ce mode de réalisation la source de puissance est, à titre d'exemple fournie par l'extérieur de l'équipement 500 au moyen d'un lien de puissance 105 comme par exemple un cordon d'alimentation secteur d'un bâtiment ou bien encore en autres un cordon d'allumé cigare d'un véhicule automobile. The magnetic field 101 produced by the power transmission coil 110 is controlled by a communication module 120 responsible for modulating said field 101 as a function of the charge control module 130. In this embodiment the source As an example, the power supply is provided by the outside of the equipment 500 by means of a power link 105, such as for example a mains power cord of a building, or else a cord of power. lit cigar of a motor vehicle.
Le champ magnétique 101 produit par ladite bobine de transmission de puissance 110 traverse le socle 502 et génère un signal de puissance dans la bobine 210 du nomade 600 située en vis-à-vis. Ce signal de puissance est utilisé pour alimenter les circuits de communication 220 et de contrôle de charge 230 du nomade 600. Comme il a été décrit précédemment, le module de contrôle 230 envoie en retour par le même canal (220, 210, 101 , 110, 120) des informations au module de contrôle 130 du transmetteur de puissance lui confirmant le besoin de puissance pour la charge de la batterie du nomade 600. The magnetic field 101 produced by said power transmission coil 110 passes through the base 502 and generates a power signal in the coil 210 of nomad 600 located opposite. This power signal is used to supply the communication circuits 220 and load control 230 of the nomad 600. As previously described, the control module 230 sends back by the same channel (220, 210, 101, 110 , 120) information to the control module 130 of the power transmitter confirming the power requirement for the load of the nomad 600 battery.
De même, le champ magnétique 301 produit par la bobine (ou antenne) de communication de données 310 est contrôlé par un module de communication 320 chargé de moduler ledit champ 301 en fonction du module de contrôle de communication 330..  Similarly, the magnetic field 301 produced by the data communication coil (or antenna) 310 is controlled by a communication module 320 responsible for modulating said field 301 as a function of the communication control module 330.
Le champ magnétique 301 produit par la bobine (ou antenne) 310 de communication de données 310 traverse le socle commun 502 et génère un signal de communication dans la bobine 410 du nomade 600 située en vis-à-vis. Ce signal de communication de données est utilisé pour alimenter les circuits de communication 420 et de contrôle de la communication 430 du nomade 600. Comme il a été décrit précédemment, le module de contrôle 430 envoie en retour par le même canal (420, 410, 301 , 310, 320) des informations au module de contrôle 330 de la communication de données lui confirmant le besoin de communication selon les protocole de communication à titre d'exemple définis par les normes de type NFC pour échanger des informations avec le nomade 600.  The magnetic field 301 produced by the data communication coil (or antenna) 310 passes through the common base 502 and generates a communication signal in the coil 410 of the nomad 600 situated opposite it. This data communication signal is used to supply the communication circuits 420 and the communication control 430 of the nomad 600. As previously described, the control module 430 sends back by the same channel (420, 410, 301, 310, 320) information to the control module 330 of the data communication confirming the need for communication according to the exemplary communication protocol defined by the NFC type standards for exchanging information with the nomad 600.
Pour un fonctionnement optimal de ce dispositif il est important que les différentes bobines soient disposées en vis-à-vis, c'est-à-dire 110 en face de 210 et 310 en face de 410. For optimal operation of this device it is important that the different coils are arranged vis-à-vis, that is to say 110 in front of 210 and 310 in front of 410.
Selon un deuxième exemple de réalisation représenté par la figure 4, le module de contrôle 130 du transmetteur inductif de puissance (110, 120, 130) et le module de contrôle 330 du module lecteur de badge à communication à champ proche (NFC) (310, 320, 330) sont reliés par un moyen d'échange d'information 505 qui permet d'améliorer la synergie de fonctionnement des ces deux systèmes. Ce moyen de communication peut être à titre d'exemple un bus de communication (entre autres : I2C, CAN, SPI, ...) ou bien encore des liaison filaires directe.
