Description

La -présente invention concerne un dispositif d'échange d'informations interactif dans les deux sens, a distance et sans contact physique, entre un- élément fixe et un ou plusieurs éléments mobiles de volume réduit (quelques cm3), dotés chacuns d'une partie informatique programmable pour le traitement et le stockage de l'information, et en plus, pour les éléments mobiles, d'une alimentation autonome. The present invention relates to a device for the interactive exchange of information in both directions, at a distance and without physical contact, between a fixed element and one or more mobile elements of reduced volume (a few cm 3), each provided with a programmable computer part for the processing and storage of information, and in addition, for mobile elements, an autonomous power supply.

Les systèmes habituellement utilisés , soit nécessitent un contact physique (par broches, pistes magnétiques, etc.), soit ne permettent qu'une identification limitée de l'élément mobile (par ex. émission d'un code). The systems usually used, either require physical contact (by pins, magnetic strips, etc.), or allow only a limited identification of the mobile element (eg emission of a code).

Le dispositif selon l'invention permet d'éliminer la nécessité du contact physique tout en conservant la possibilité d'échange d'informations, leur traitement et leur stockage dans l'élément mobile. The device according to the invention eliminates the need for physical contact while retaining the possibility of exchanging information, processing and storing it in the mobile element.

L'élément mobile réunit à cet effet, dans le même dispositif physique, sous un format réduit faisant appel à une électronique à haute intégration, un microprocesseur et ses mémoires associées (R.O.-M. et R.A.M.), un émetteur-récepteur à haute fréquence, une antenne intégrée (non apparente) et omnidirectionnelle, et une alimentation qui peut être rechargeable ou interchangeable et lui assure une autonomie de fontionnement pendant une durée déterminée. The mobile element brings together for this purpose, in the same physical device, in a reduced format using high integration electronics, a microprocessor and its associated memories (RO-M. And RAM), a high frequency transceiver. , an integrated (not visible) and omnidirectional antenna, and a power supply which can be rechargeable or interchangeable and ensures its operating autonomy for a determined period.

L'élément fixe comporte les mêmes éléments, sans contraintes de taille ni de puissance, et son antenne d'émission-réception permet la délimitation d'un volume à l'intérieur duquel l'élément mobile doit se situer pour que l'échange d'informations puisse s'effectuer. The fixed element has the same elements, without size or power constraints, and its transmit-receive antenna allows the delimitation of a volume inside which the mobile element must be located so that the exchange of information can be done.

L'échange d'informations utilise le support d'ondes électromagnétiques en hyper fréquence, de portée réduite (O à 10 mètres) mais capables de traverser des épaisseurs réduites de matériaux non métalliques divers (vétements, boitiers, eau, etc.). Les ondes sont modulées en fréquence pour la transmission dans un sens et en amplitude pour la transmission dans l'autre, afin d'éviter les interférences entre les signaux.  The exchange of information uses the support of electromagnetic waves in hyper frequency, of reduced range (0 to 10 meters) but capable of crossing reduced thicknesses of various non-metallic materials (clothing, boxes, water, etc.). The waves are frequency modulated for transmission in one direction and amplitude for transmission in the other, in order to avoid interference between the signals.

L'élément mobile comporte un système de veille permettant une consommation réduite pour l'entretien de ses mémoires. La réception par l'élément mobile d'une onde émise par l'élément- fixe déclanche l'activation du sytème de veille et l'alimentation à régime normal des composants de l'élément, qui décode lue signal reçu, élabore - le message de réponse et émeut~ le signal correspondant vers l'élément fixe. The mobile element includes a standby system allowing reduced consumption for the maintenance of its memories. The reception by the mobile element of a wave emitted by the fixed element triggers the activation of the standby system and the supply at normal speed of the components of the element, which decodes the received signal, elaborates - the message response and moves ~ the corresponding signal to the fixed element.

Selon des variantes de réalisation, l'alimentation de l'élément mobile est un condensateur a décharge -Iente et recharge rapide ou une batterie miniaturisée, la recharge de l'un ou de l'autre s'effectuant par une connexion physique de l'élément mobile à un dispositif de recharge adéquat par l'intermédiaire de connecteurs intégrés à l'élément mobile. According to alternative embodiments, the supply of the movable element is a fast-discharge and fast-charging capacitor or a miniaturized battery, the recharging of one or the other being effected by a physical connection of the mobile element to a suitable recharging device via connectors integrated into the mobile element.

Selon une variante de réalisation, l'élément mobile est équipé de connecteurs et son organisation interne est réalisée de façon a permettre, lors d'une connexion de l'élément mobile à un dispositif adéquat, de modifier le contenu de ses mémoires et/ou de son programme interne mais à la base la modification du contenu des mémoires s'effectue a distance. According to an alternative embodiment, the mobile element is equipped with connectors and its internal organization is carried out so as to allow, when the mobile element is connected to an appropriate device, to modify the content of its memories and / or of its internal program but basically the modification of the content of the memories is done remotely.

Le dispositif selon l'invention est particulièrement destiné à toutes les applications dans lesquelles une détection de présence ou de passage (d'une personne physique ou d'un objet porteurs de l'élément mobile) est nécessaire, et peut entralner soit une action physique (par exemple l'ouverture d'une porte, le déclanchement d'une alarme, etc.), soit l'enregistrement de cette présence dans un système informatique et les actions de gestion qui en découlent, soit une modification des données enregistrées dans la mémoire de l'élément mobile pour une détection ultérieure, soit toute combinaison de ces diverses possibilités. The device according to the invention is particularly intended for all applications in which a presence or passage detection (of a natural person or of an object carrying the mobile element) is necessary, and can result in either a physical action (for example the opening of a door, the triggering of an alarm, etc.), either the recording of this presence in a computer system and the management actions which result from it, or a modification of the data recorded in the memory of the mobile element for later detection, or any combination of these various possibilities.

I1 est donc utilisable dans toutes les applications de contrôle, de sécurité, de péage, etc. It can therefore be used in all control, security, toll applications, etc.

Dans une extension possible de l'utilisation du dispositif selon l'invention, l'élément mobile peut être couplé de manière intégrée a des capteurs spécifiques et délivrer les données acquises a partir de ces capteurs lors de son passage dans le champ d'un elément fixe.  In a possible extension of the use of the device according to the invention, the mobile element can be coupled in an integrated manner to specific sensors and deliver the data acquired from these sensors during its passage in the field of an element. fixed.

Selon une variante d'utilisation du dispositif, l'élément dit "fixe" peut être embarqué dans un véhicule mobile et les éléments dits "mobiles" peuvent être disposés à demeure dans des endroits fixes, leur fonctions respectives restant les mêmes.  According to a variant use of the device, the so-called "fixed" element can be loaded on a mobile vehicle and the so-called "mobile" elements can be permanently installed in fixed places, their respective functions remaining the same.
