Description

La présente invention concerne un dispositif de traitement d'informations au moyen de deux terminaux pourvus de moyens pour recevoir, transmettre et visualiser des informations. The present invention relates to an information processing device by means of two terminals provided with means for receiving, transmitting and displaying information.

Dans les dispositifs de ce type, des terminaux possédant un microprocesseur échangent et traitent des informations par l'intermédiaire de liaisons électriques telles que des bus de données et des prises de connections électriques. In such devices, terminals having a microprocessor exchange and process information by means of electrical connections such as data buses and sockets of electrical connections.

Selon les applications, il peut être avantageux que certains terminaux servent de périphériques portables, dialogant avec un terminal à poste fixe, lorsqu'ils sont reliés par des lignes et connections électriques. Depending on the application, it may be advantageous that some terminals are used as portable devices, dialogant with a stationary terminal, when connected by electrical lines and connections.

Cette conception présente l'inconvénient de réduire la mobilité des terminaux périphériques. This design has the disadvantage of reducing the mobility of peripheral devices. Même lorsque le dialogue est limité dans le temps, par exemple en fin de journée pour centraliser toutes les informations, la nécessité d'établir des connexions électriques, peu fiables dans le temps, est un handicap pour des utilisateurs non avertis. Even when the dialogue is limited in time, for example in the late afternoon to centralize all the information, the need for electrical connections, unreliable over time, is a liability for unsophisticated users. Il en est de même pour les périodes de recharge en énergie des batteries autonomes dont sont équipés les terminaux périphériques. It is the same for recharging periods in autonomous energy batteries which are equipped peripheral devices.

Le dispositif selon l'invention a pour but d'éviter ces inconvénients. The device of the invention aims to avoid these drawbacks. Pour ce faire, seul le terminal à poste fixe est relié à une source d'énergie extérieure et il comprend des moyens qui, associés sans liaison matérielle avec un terminal périphérique portable équipé de moyens équivalents, permettent de dialoguer et de transmettre de l'énergie entre eux. To do this, only the stationary terminal is connected to an external power source and includes means which, without associated hardware connection with a portable device terminal with equivalent means allow to engage and transmit power between them. Pour la transmission d'énergie, ces moyens consistent en un couplage magnétique entre le poste fixe et le terminal périphérique portable. For the transmission of energy, these means consist of a magnetic coupling between the fixed station and the mobile device terminal. Pour le dialogue, ces moyens consistent en des émetteurs et des récepteurs optoélectroniques. Dialogue, these means consist of optoelectronic transmitters and receivers. Tous ces moyens sont rendus opérationnels lorsque les deux terminaux sont accouplés, c'est à dire disposés au contact l'un de l'autre. All these means are made operational when the two devices are coupled, ie arranged in contact with one another.

Le dessin annexé illustre, à titre d'exemple, un mode de réalisation du dispositif conforme à la présente invention. The accompanying drawing illustrates, by way of example, an embodiment of the device according to the present invention.

La figure 1 représente deux terminaux prévus pour être momentanément associés l'un è l'autre. 1 shows two terminals adapted to be temporarily associated è one another.

La figure 2 est une représentation synoptique d'un terminal fixe et d'un terminal périphérique portable. Figure 2 is a block diagram of a fixed terminal and a portable terminal device.

Tel que représenté figure 1, le dispositif comprend un terminal fixe 1 incorporé dans un boitier moulé et alimenté en énergie extérieure au moyen d'un cordon de raccordement 14. As shown in Figure 1, the device comprises a fixed terminal 1 incorporated in a molded case and supplied with external power by means of a patch cord 14.

Ce boitier a des formes appropriées, par exemple bords 8 et surface 9, pour imposer une position bien définie entre les terminaux lorsque le terminal portable 2 est posé sur le terminal à poste fixe 1. Cette position précise et constante permet à des moyens de transmission d'énergie 12, 22 d'une part et à des moyens optoélectroniques 10, 11, 20, 2f d'autre part, d'être respectivement disposés en vis-à-vïs et à proximité les uns des autres pendant les périodes de transfert d'énergie et de dialogue. This box has the appropriate forms, such edges 8 and 9 surface to impose a defined position between the terminals when the portable terminal 2 is placed on the stationary terminal 1. This precise and consistent position allows transmission means energy 12, 22 on the one hand and optoelectronic means 10, 11, 20, 2f on the other hand, being respectively arranged in facing relation and in close proximity to each other during the transfer periods energy and dialogue.

Ce transfert d'énergie entre les terminaux 1 et 2 se fait par un couplage magnétique réalisé au moyen de deux bobines 22 et 12 qui fonctionnent en transformateur lorqu'elles sont disposées à proximité l'une de l'autre. This transfer of energy between the terminals 1 and 2 is realized by a magnetic coupling by means of two coils 22 and 12 which operate lorqu'elles transformer are arranged close to one another.

L'énergie est fournie de l'extérieur à une alimentation 15 qui, après redressement du 220 volts alternatif et filtrage, alimente en courant continu un oscillateur de puissance 16. Power is supplied from outside to a power supply 15 which, after recovery of the 220 volts AC and filtering, DC supplies a power oscillator 16.

Cet oscillateur délivre une tension alternative à fréquence élevée, de l'ordre de 30 KH5 appliquée sur la bobine primaire 12. This oscillator delivers an alternating voltage at high frequency, of the order of 30 KH5 applied to the primary coil 12.

La bobine secondaire 22, du type demi-pot ferrite, consiste en deux bobinages distincts afin d'obtenir deux tensions qui, après redressement par ponts de diodes et circuits de régulation de courant 23, servent à la recharge de deux batteries distinctes 24, destinées à alimenter d'une part des circuits électromécaniques, tels que moteur d'imprimante en 24 volts et d'autre part des circuits électroniques en 5 volts, tels que microprocesseur 25, mémoire 26 et coupleur 27 pour saisir des informations de l'extérieur, à partir de cartes à microcircuits par exemple. The secondary coil 22, the half-pot type ferrite, consists of two separate windings in order to obtain two voltages which, after rectification by diode bridges and current regulating circuits 23, used for charging two separate batteries 24, for supplying a part of the electromechanical circuits, such as printer engine 24 volts and the other electronic circuits at 5 volts, such as microprocessor 25, memory 26 and coupler 27 to input information from the outside, from microcircuit cards for example.

La mémoire 26 contient en particulier le programme d'exploitation du terminal portable. The memory 26 contains in particular the operating program of the portable terminal. Ce programme est transféré à partir du poste fixe par le dispositif de transmission optoélectronique. This program is transferred from the fixed position by the optoelectronic transmission device.

Afin d'éviter un échauffement exagéré du bobinage primaire 12 lorsque les deux terminaux sont séparés, ce primaire sert également de capteur de présence du terminal portable. To avoid excessive heating of the primary winding 12 when the two terminals are separated, primary also serves as a presence sensor of the portable terminal. Pour ce faire, on mesure le courant qui parcourt le primaire 12. To do this, we measure the current passing through the primary 12.

En l'absence du terminal portable, le faible niveau de ce courant est détecté par un comparateur pour agir sur un relais qui réduit la puissance délivrée dans le primaire, par réduction de tension. In the absence of the portable terminal, the low level of this current is detected by a comparator to act on a relay which reduces the power delivered to the primary, for voltage reduction.

Lorsque la présence du bobinage secondaire 22 est ainsi détectée l'échange des informations, entre le microprocesseur 25 du terminal portable et le microprocesseur 17 et sa mémoire 18, du terminal à poste fixe, se fait en mode série asynchrone à une vitesse par exemple de 9600 bauds au moyen d'émetteurs 20, 11 et de récepteurs 10, 21 du type à infrarouge. When the presence of the secondary winding 22 is thus detected the exchange of information between the microprocessor 25 of the portable terminal and the microprocessor 17 and its memory 18, the stationary terminal, is in asynchronous series mode to a speed of e.g. 9600 by means of transmitters 20, 11 and receivers 10, 21 of the infrared type.

Enfin, le terminal à poste fixe 1 peut échanger des informations avec l'extérieur au moyen d'un modem 13 lui permettant l'accès au réseau téléphonique 19. De son côté, le terminal portable 2 possède un clavier 28 d'introduction de données, un afficheur 30, une imprimante 29, et un coupleur 27 pour carte à microcircuits. Finally, the terminal fixed station 1 can exchange information with the outside by means of a modem 13 allowing it access to the telephone network 19. In turn, the portable terminal 2 has a keyboard 28 for data input , a display 30, a printer 29, and a coupler 27 for microcircuit card.

Le dispositif selon l'invention peut être utilisé dans tous les cas où le traitement de l'information nécessite l'utilisation de terminaux à poste fixe et de terminaux portables. The device of the invention can be used in all cases where the information processing requires the use of terminals stationary and portable terminals.
