Description

La présente invention concerne les ensembles électroniques équipés d'un clavier à touches relié à un microprocesseur comportant une mémoire et, plus particulièrement, les claviers à touches de tels ensembles électroniques. The present invention relates to electronic assemblies equipped with a keyboard with keys connected to a microprocessor comprising a memory and, more particularly, the keyboards with keys of such electronic assemblies.
Les claviers à touches équipent sensiblement tous les ensembles électroniques, tels que les téléphones portables, les calculateurs de poche, les micro-ordinateurs, les dispositifs d'accès à des lieux protégés, les distributeurs de billets de banque, les commandes au tableau de bord d'un véhicule automobile ou d'un avion, etc..Keyboards are used in almost all electronic systems, such as mobile phones, pocket calculators, microcomputers, access devices to protected places, cash dispensers, dashboard controls a motor vehicle or an airplane, etc.
D'une façon générale, les touches de tels claviers sont souvent équipées d'un moyen d'éclairage intégré permettant leur utilisation dans la pénombre ou la nuit, ou bien permettant de déterminer leur actionnementIn general, the keys of such keyboards are often equipped with an integrated lighting means allowing them to be used in darkness or at night, or else making it possible to determine their actuation.
A titre d'exemples, les documents EP-A-0 575 767 et EP-A- 0 508 563 décrivent un tel clavier pourvu d'un moyen d'éclairage permettant d'illuminer au moins une partie supérieure de chacune des touches. Quelquefois, chaque touche est entourée d'un manchon plastique translucide transmettant une lumière jusqu'à la face avant des touches, comme prévu dans le document US-A-4 806 908. De façon alternative, une ouverture est prévue dans chaque touche, ouverture derrière laquelle est située une diode électroluminescente, comme prévu dans le document DE-A-29619920.By way of example, documents EP-A-0 575 767 and EP-A-0 508 563 describe such a keyboard provided with lighting means making it possible to illuminate at least an upper part of each of the keys. Sometimes, each key is surrounded by a translucent plastic sleeve transmitting a light up to the front face of the keys, as provided in the document US-A-4 806 908. Alternatively, an opening is provided in each key, opening behind which is located a light emitting diode, as provided in document DE-A-29619920.
Il est également connu des claviers dont certaines touches peuvent avoir individuellement plusieurs usages. Dans un tel cas, l'éclairage ponctuel ou non d'une touche, ou la couleur d'un tel éclairage, permet à l'utilisateur de savoir quel est le rôle exact de la touche à un moment donné. Un tel clavier est, par exemple, décrit dans le document DE-A-29800924.Keyboards are also known, certain keys of which can individually have several uses. In such a case, the spot lighting or not of a key, or the color of such lighting, allows the user to know what is the exact role of the key at a given moment. Such a keyboard is, for example, described in document DE-A-29800924.
Le document WO-A-9512841 décrit un clavier dit interactif selon lequel la manipulation de certaines touches détermine des fonctions spéciales, un circuit électrique matriciel permettant de limiter ainsi le nombre des touches actives.Document WO-A-9512841 describes a so-called interactive keyboard according to which the manipulation of certain keys determines special functions, an electrical matrix circuit making it possible to limit the number of active keys.
Le document EP-A-0 670 554 décrit un dispositif à clavier spécial, écran et stylo, les touches ayant un éclairage interne permettant à l'ordinateur de mettre en relief la touche attendue. Il y a là une forme d'utilisation du clavier comme moyen d'aide à l'écriture, mais il n'est nullement question d'utiliser le clavier comme moyen d'affichage lorsque le système est aveugle, c'est à dire sans écran d'affichage.The document EP-A-0 670 554 describes a device with a special keyboard, screen and pen, the keys having an internal light enabling the computer to highlight the expected key. This is a form of using the keyboard as a writing aid, but there is no question of using the keyboard as a display when the system is blind, i.e. without display screen.
Le document GB-A-2 167 218 décrit simplement un clavier dont chaque touche peut avoir plusieurs effets, un éclairage indiquant l'effet en cours.Document GB-A-2 167 218 simply describes a keyboard, each key of which can have several effects, a light indicating the current effect.
Le document JP-A-62235624 décrit un clavier dont les touches opérationnelles sont éclairées dans un but clairement tutorial.The document JP-A-62235624 describes a keyboard whose operational keys are lit for a clearly tutorial purpose.
Le document JP-A-06020155 décrit également un clavier pour débutants avec allumage séquentiel de la touche suivante attendue.The document JP-A-06020155 also describes a keyboard for beginners with sequential lighting of the next expected key.
La présente invention se situe dans ce contexte et a pour but d'utiliser l'éclairage des touches ou de certaines de celles-ci pour assurer une autre fonction en interactivité avec le microprocesseur de l'ensemble électronique.The present invention is situated in this context and aims to use the lighting of the keys or of some of these to provide another function in interactivity with the microprocessor of the electronic assembly.
L'invention concerne donc plus précisément un ensemble comprenant un clavier à touches et un microprocesseur comportant une mémoire et relié à celui-ci, au moins certaines de ces touches étant chacune équipées d'un moyen d'éclairage intégré. Selon l'invention, le moyen d'éclairage intégré est susceptible de constituer un moyen d'affichage pour le microprocesseur.The invention therefore relates more precisely to an assembly comprising a keyboard with keys and a microprocessor comprising a memory and connected to it, at least some of these keys being each equipped with an integrated lighting means. According to the invention, the integrated lighting means is capable of constituting a display means for the microprocessor.
De préférence, le moyen d'éclairage intégré constitue un moyen d'affichage en réponse à un code spécifique pianoté sur les touches du clavier.Preferably, the integrated lighting means constitutes a display means in response to a specific code typed on the keys of the keyboard.
De façon avantageuse, le microprocesseur inclut une horloge et commande l'activation séquentielle du moyen d'éclairage de chacune des touches pour délivrer visuellement un code à l'utilisateur. Ce code est, de préférence, choisi parmi les codes d'état, les codes d'erreurs et les codes calandaires.Advantageously, the microprocessor includes a clock and controls the sequential activation of the lighting means of each of the keys to visually deliver a code to the user. This code is preferably chosen from the status codes, error codes and calendar codes.
Le code peut également correspondre à une ligne déterminée de la mémoire du microprocesseur.The code can also correspond to a determined line of the microprocessor memory.
L'invention sera mieux comprise, et d'autres buts, avantages et caractéristiques de celle-ci apparaîtront plus clairement à la lecture de la description qui suit de modes préférés de réalisation donnés à titre non limitatif et à laquelle une planche de dessins est annexée sur laquelle:The invention will be better understood, and other objects, advantages and characteristics thereof will appear more clearly on reading the following description of preferred embodiments given without limitation and to which a plate of drawings is attached. on which:
La Figure unique représente schématiquement un ensemble comprenant un clavier à touches et un microprocesseur conformément à un mode de réalisation préféré de l'invention.The single FIGURE schematically represents an assembly comprising a keyboard with keys and a microprocessor in accordance with a preferred embodiment of the invention.
Comme l'homme du métier l'aura compris, l'invention s'adresse plus particulièrement, mais non exclusivement, à un système aveugle, c'est à dire ne comportant pas un écran d'affichage. Un tel système est généralement utilisé pour commander un dispositif électromécanique, par exemple le pêne d'une serrure d'une porte en réponse à un code d'accès déterminé. Mais l'invention peut être mise en oeuvre dans les systèmes comportant un écran d'affichage, notamment lorsqu'il existe un risque que cet écran d'affichage subisse un dysfonctionnement ou fasse l'objet d'un vandalisme quelconque.As those skilled in the art will have understood, the invention is more particularly, but not exclusively, directed to a blind system, that is to say one not comprising a display screen. Such a system is generally used to control an electromechanical device, for example the bolt of a door lock in response to a determined access code. However, the invention can be implemented in systems comprising a display screen, in particular when there is a risk that this display screen may malfunction or be subject to some form of vandalism.
En référence à la Figure unique, un clavier K dont au moins certaines touches sont équipées d'un moyen d'éclairage intégré, est relié à un microprocesseur μP, lequel microprocesseur μP commande un dispositif D, par exemple le pêne précédemment cité. En fonctionnement normal, l'utilisateur pianote sur les touches du clavier K pour donner une instruction. L'information est directement transmise au microprocesseur μP par l'intermédiaire de la liaison 8. Le microprocesseur μP vérifie alors les données reçues et, en fonction de ces données, commande l'actionnement du dispositif D.With reference to the single FIGURE, a keyboard K of which at least certain keys are equipped with an integrated lighting means, is connected to a microprocessor μP, which microprocessor μP controls a device D, for example the bolt previously mentioned. In normal operation, the user taps on the keys of the keyboard K to give an instruction. The information is directly transmitted to the microprocessor μP via the link 8. The microprocessor μP then verifies the data received and, according to this data, controls the actuation of the device D.
Pour des raisons de maintenance, de diagnostic, ou même de mise en service ou hors service, par exemple, un technicien peut avoir à intervenir sur cet ensemble. Il pianote alors son propre code d'identification sur le clavier K Le microprocesseur μP reconnaît alors qu'il ne s'agit pas d'actionner le dispositif D. Le technicien indique ensuite par voie de codes appropriés au microprocesseur μP la nature de ce qu'il désire savoir, et le microprocesseur renvoie l'information demandée codée par la liaison 12 au clavier K, par adressage sélectif des touches comportant un moyen d'éclairage intégré.For maintenance, diagnostic, or even commissioning or out of service reasons, for example, a technician may have to work on this assembly. He then taps his own identification code on the keypad K The microprocessor μP then recognizes that it is not a question of actuating the device D. The technician then indicates by means of appropriate codes to the microprocessor μP the nature of what 'he wishes to know, and the microprocessor returns the requested information coded by the link 12 to the keyboard K, by selective addressing of the keys comprising an integrated lighting means.
Il peut également introduire des instructions particulières, par exemple une mise en service ou hors service différée, le microprocesseur μP renvoyant alors vers le clavier K un simple accusé- réception ou équivalentIt can also introduce specific instructions, for example a delayed start-up or shutdown, the microprocessor μP then sending a simple acknowledgment or equivalent to the keyboard K
Cette information codée apparaît alors au technicien sous forme d'un éclairage de certaines touches du clavier K.This coded information then appears to the technician in the form of an illumination of certain keys of the keyboard K.
De préférence, pour augmenter le nombre d'informations codées susceptibles d'être fournies au technicien, une horloge H reliée au microprocesseur μP permet de commander l'éclairage des touches concernées de façon séquentielle, chaque touche concernée restant allumée successivement, par exemple pendant 2 secondes chacune.Preferably, to increase the number of coded information likely to be supplied to the technician, a clock H connected to the microprocessor μP makes it possible to control the lighting of the keys concerned sequentially, each concerned key remaining lit successively, for example for 2 seconds each.
Le technicien peut ainsi facilement obtenir un code d'état, un code d'erreur, un code calandaire ou même lire une ligne déterminée de la mémoire du microprocesseur μP.The technician can thus easily obtain a status code, an error code, a calendar code or even read a determined line from the memory of the μP microprocessor.
Le même moyen peut aussi être utilisé par le technicien pour modifier le ou les code(s) de fonctionnement normal.The same means can also be used by the technician to modify the normal operating code or codes.
Le même moyen peut également être utilisé par un utilisateur normal pour demander au microprocesseur μP de lui délivrer un nouveau code temporaire pour la commande du dispositif D. Ceci est généralement utile lorsque le dispositif D est une porte à accès contrôlé et qu'un code temporaire doit être fourni à un tiers invité.The same means can also be used by a normal user to request the microprocessor μP to issue him a new temporary code for the control of device D. This is generally useful when device D is a controlled access door and a temporary code must be provided to a guest third party.
On comprendra aisément que ce moyen d'affichage peut trouver de très nombreuses autres applications que celles qui viennent d'être décrites.It will be readily understood that this display means can find many other applications than those which have just been described.
A titre d'exemples, on peut citer une mise en service ou hors service horadatée ou différée, la réalisation d'un diagnostic, le remplacement d'un écran d'affichage défectueux, etc..By way of examples, mention may be made of a timed or deferred commissioning or deactivation, the carrying out of a diagnosis, the replacement of a defective display screen, etc.
Bien évidemment, pour que la fonction d'affichage qui vient d'être décrite ci-avant fonctionne correctement, le microprocesseur μP devra préalablement éteindre le moyen d'éclairage de l'ensemble des touches du clavier K, de telle manière qu'aucune erreur ne puisse se produire lorsque le clavier fonctionne en tant que moyen d'affichage.Obviously, for the display function which has just been described above to function correctly, the microprocessor μP must first turn off the lighting means of all the keys of the keyboard K, so that no error cannot be occur when the keyboard functions as a display medium.
De façon avantageuse, le code d'identification du technicien peut être un code variable obtenu, par exemple, en combinaison de codes temporaires fonction de la date et de l'heure, et de tout autre code. On évite ainsi facilement le vandalisme et /ou le piratage des données en mémoire du microprocesseur μP.Advantageously, the technician's identification code can be a variable code obtained, for example, in combination with temporary codes depending on the date and time, and any other code. This easily prevents vandalism and / or piracy of the data in memory of the μP microprocessor.
Pour des raisons de sécurité additionnelle, on peut prévoir que les codes en mémoire du microprocesseur soient auto-détruits si le microprocesseur μP détecte plusieurs tentatives d'approche erronées. Le système devient alors inutilisable sans l'intervention du constructeur pour recharger la mémoire.For additional security reasons, it can be provided that the codes in memory of the microprocessor are self-destructed if the microprocessor μP detects several erroneous approach attempts. The system then becomes unusable without the intervention of the manufacturer to reload the memory.
On obtient donc bien, en mettant en oeuvre l'invention, un système de très grande sécurité et à maintenance rendue plus aisée. La transformation d'un clavier en afficheur par adressage sélectif des touches du clavier apporte ainsi une importante puissance complémentaire aux systèmes existants.Thus, by implementing the invention, a very high security and maintenance system made easier is obtained. The transformation of a keyboard into a display by selective addressing of the keys on the keyboard thus brings significant additional power to existing systems.
Bien que l'on ait représenté et décrit ce que l'on considère actuellement être les modes de réalisation préférés de la présente invention, il est évident que l'Homme de l'Art pourra y apporter différents changements et modifications sans sortir du cadre de la présente invention tel que défini ci-après. Although we have represented and described what are currently considered to be the preferred embodiments of the present invention, it is obvious that those skilled in the art will be able to make various changes and modifications thereto without departing from the scope of the present invention as defined below.
