Description
PROCEDE DE TRANSMISSION DE SIGNAUX VOIX/DONNES ENTRE UN APPAREIL DE BASE ET UN APPAREIL AUXILIAIREMETHOD FOR TRANSMITTING VOICE / DATA SIGNALS BETWEEN A BASIC DEVICE AND AN AUXILIARY DEVICE
La présente invention se rapporte au domaine de la transmission de signaux 5 voix/données, ainsi qu'à celui de la transmission d'énergie.The present invention relates to the field of transmission of 5 voice / data signals, as well as to that of energy transmission.
La présente invention se rapporte plus particulièrement à un procédé de transmission de signaux voix/données entre un appareil de base, comme par exemple un terminal téléphonique et un appareil secondaire, du type ordinateur, lecteur/enregisteur numérique, ... ou un appareil intermédiaire émetteur/récepteur et notamment 0 émetteur/récepteur Bluetooth, à l'aide d'une connexion, ledit appareil secondaire ou ledit appareil intermédiaire comportant au moins un accumulateur de charge pour son alimentation électrique.The present invention relates more particularly to a method of transmitting voice / data signals between a basic device, such as for example a telephone terminal and a secondary device, of the computer, digital player / recorder type, or an intermediate device. transmitter / receiver and in particular 0 Bluetooth transmitter / receiver, using a connection, said secondary device or said intermediate device comprising at least one charge accumulator for its electrical supply.
Actuellement, pour l'alimentation des appareils intermédiaires ou 5 secondaires liés par une transmission de signal voix/données avec un appareil de base, soit l'appareil intermédiaire ou secondaire comporte sa propre alimentation électrique, qu'il faut raccorder à un réseau électrique ou au secteur, soit l'appareil intermédiaire ou secondaire comporte un accumulateur de charge, c'est-à-dire une batterie, qu'il faut recharger régulièrement. 0 Dans le cas où l'appareil de base est un appareil portable, comportant lui- même un accumulateur de charge, il est bien sûr préférable que l'appareil intermédiaire ou secondaire comporte lui aussi un accumulateur de charge.Currently, for the supply of intermediate or secondary devices linked by a voice / data signal transmission with a basic device, either the intermediate or secondary device has its own power supply, which must be connected to an electrical network or in the sector, either the intermediate or secondary device has a charge accumulator, that is to say a battery, which must be recharged regularly. 0 In the case where the basic device is a portable device, itself comprising a charge accumulator, it is of course preferable that the intermediate or secondary device also comprises a charge accumulator.
Un inconvénient de cette situation est qu'il faut prévoir, en sus de la 5 connexion pour la transmission de signaux voix/données entre l'appareil de base et l'appareil intermédiaire ou secondaire, une connexion pour la transmission de l'énergie électrique vers l'accumulateur de charge de l'appareil intermédiaire ou secondaire.A disadvantage of this situation is that, in addition to the connection for the transmission of voice / data signals between the basic device and the intermediate or secondary device, it is necessary to provide a connection for the transmission of electrical energy. to the charge accumulator of the intermediate or secondary device.
La demande internationale de brevet N° WO 01/08386 illustre une telle 0 situation. Comme on peut le voir sur la figure 3, un câblage supplémentaire est prévu dans la partie basse de l'appareil intermédiaire pour le rechargement de l'accumulateur de cet appareil.
La présente invention entend remédier aux inconvénients de l'art antérieur en proposant que la connexion utilisée pour la transmission de signaux voix/données entre l'appareil de base et l'appareil intermédiaire ou secondaire soit utilisée pour transmettre l'énergie nécessaire au chargement et rechargement de l'accumulateur de charge associé à l'appareil intermédiaire ou secondaire, afin de permettre de simplifier le câblage de l'appareil intermédiaire ou secondaire, ainsi que son usage.International patent application No. WO 01/08386 illustrates such a situation. As can be seen in Figure 3, additional wiring is provided in the lower part of the intermediate device for recharging the accumulator of this device. The present invention intends to remedy the drawbacks of the prior art by proposing that the connection used for the transmission of voice / data signals between the basic device and the intermediate or secondary device be used to transmit the energy necessary for charging and recharging of the charge accumulator associated with the intermediate or secondary device, in order to simplify the wiring of the intermediate or secondary device, as well as its use.
Pour ce faire, la présente invention est du type décrit ci-dessus et elle est remarquable, dans son acception la plus large, en ce que ladite connexion présente deux modes de fonctionnement : un premier mode dans lequel elle permet de charger ledit accumulateur de charge et transmettre des signaux voix/données et un deuxième mode dans lequel elle ne peut que transmettre des signaux voix/données.To do this, the present invention is of the type described above and it is remarkable, in its broadest sense, in that said connection has two operating modes: a first mode in which it allows said charge accumulator to be charged and transmit voice / data signals and a second mode in which it can only transmit voice / data signals.
Le signal voix/données étant un signal analogique ou numérique, la distinction entre les deux modes de fonctionnement se fait en détectant et en analysant la valeur de la tension du signal : en dessous d'un seuil donné, il s'agit d'un signal voix/données et en dessus de ce seuil, il s'agit d'une tension de rechargement de l'accumulateur.The voice / data signal being an analog or digital signal, the distinction between the two operating modes is made by detecting and analyzing the value of the signal voltage: below a given threshold, it is a voice / data signal and above this threshold, it is a battery recharge voltage.
La connexion utilise de préférence quatre signaux :The connection preferably uses four signals:
- un signal de masse, - un signal de sélection de mode, et- a mass signal, - a mode selection signal, and
- deux signaux de transmission de voix/données.- two voice / data transmission signals.
Le deuxième mode permet également de préférence de configurer le fonctionnement dudit appareil intermédiaire ou secondaire.The second mode also preferably makes it possible to configure the operation of said intermediate or secondary device.
Le passage d'un mode à un autre est opéré de préférence automatiquement par détection de la tension dans ladite connexion.The transition from one mode to another is preferably effected automatically by detecting the voltage in said connection.
La présente invention se rapporte également à une connexion permettant de mettre en œuvre le procédé, ainsi qu'à un appareil intermédiaire ou secondaire comportant une connexion permettant de mettre en œuvre le procédé selon l'invention.The present invention also relates to a connection making it possible to implement the method, as well as to an intermediate or secondary device comprising a connection making it possible to implement the method according to the invention.
Avantageusement, lorsque l'accumulateur de charge de l'appareil secondaire ou de l'appareil intermédiaire doit être rechargé, la présente invention permet d'utiliser la connexion utilisée pour la transmission de donnée dans le but de permettre d'alimenter l'accumulateur de charge en énergie de charge.
Avantageusement, la détection de la tension dans ladite connexion est automatique, afin d'en déduire automatiquement, lorsque la valeur seuil est dépassée, qu'il s'agit d'une tension de rechargement de l'accumulateur et entamer alors un cycle de rechargement de l'accumulateur.Advantageously, when the accumulator of charge of the secondary apparatus or of the intermediary apparatus must be recharged, the present invention makes it possible to use the connection used for the transmission of data with the aim of making it possible to supply the accumulator of charge in charge energy. Advantageously, the detection of the voltage in said connection is automatic, in order to automatically deduce therefrom, when the threshold value is exceeded, that it is a recharging voltage of the accumulator and then start a recharging cycle of the accumulator.
