Description

La presente invention concerne un dispositif permettant de déterminer et d'afficher, de façon totalement automatique, les canaux ou fréquences des stations d'émissions radiophoniques, plus particulièrement dans la bande modulation de fréquence (fur).  The present invention relates to a device making it possible to determine and display, completely automatically, the channels or frequencies of radio transmission stations, more particularly in the frequency modulation band (fur).

La portée géographique des emetteurs en modulation de fréquence est relativement limitee, ce qui oblige le conducteur d'un véhicule auto bile, lorsque le récepteur est monté sur un tel véhicule, à rechercher systématiquement tout le long du trajet qu'il parcourt quelle est la fréquence utilisée par la station émettrice qu'il veut écouter, dans la zone géographique où il se trouve. The geographic range of transmitters in frequency modulation is relatively limited, which obliges the driver of an auto bile vehicle, when the receiver is mounted on such a vehicle, to systematically search throughout the journey he is traveling for what is the frequency used by the transmitting station it wants to listen to, in the geographic area where it is located.

Bien que la plupart des autoradios modernes actuellement commercialisées disposent d'un système automatique de recherche de fréquence, il n'en existe aucun à l'heure actuelle qui permette d'afficher automatiquement les fréquences ou les canaux pouvant etre captés dans une zone géographique déterminée, c'est-àdire dans la zone où se situe l'utilisateur. L'invention se propose d'apporter un tel dispositif.Although most modern car radios currently on the market have an automatic frequency search system, there is none currently available that automatically displays the frequencies or channels that can be received in a specific geographic area. , i.e. in the area where the user is located. The invention proposes to provide such a device.

En conséquence cette invention a pour objet un dispositif permettant de déterminer et d'afficher autonratiquement les canaux ou fréquences radio disponibles, notamment dans la bande modulation de fréquence < FN), dans une zone ou se situe l'utilisateur, et notamment dans une aire géographique où circule un véhicule automobile équipé d'un autoradio, caractérisé en ce qu'il comprend
- une mémoire dans laquelle sont stockées les données relatives aux différents canaux et fréquences disponibles dans les zones respectives
- une unité de traitement des informations délivrées par ladite memoire
- un système de recherche permettant à l'utilisateur de transmettre à la mémoire une information concernant la zone dont il veut connaitre les canaux ou fréquences radio disponibles et,
- un système d'affichage électronique des données fournissant à l'utilisateur, après interrogation, les informations relatives aux canaux et fréquences disponibles dans la zone désirée.Consequently, the subject of this invention is a device making it possible to automatically determine and display the available radio channels or frequencies, in particular in the frequency modulation band (FN), in an area where the user is located, and in particular in an area geographic area where a motor vehicle fitted with a car radio circulates, characterized in that it comprises
- a memory in which the data relating to the different channels and frequencies available in the respective zones are stored
- a unit for processing the information delivered by said memory
- a search system allowing the user to transmit to the memory information concerning the area of which he wants to know the available radio channels or frequencies and,
- an electronic data display system providing the user, after interrogation, with information relating to the channels and frequencies available in the desired area.

D'autres caractéristiques et avantages de la présente invention ressortiront de la description faite ci-après en référence au dessin annexé qui en illustre un exemple de realisation dépourvu de tout caractère limitatif. Sur le dessin
- la figure 1 est une vue schématique en perspective représentant un exemple de réalisation du dispositif objet de l'invention et,
- la figure 2 est un schéma par bloc illustrant- le dispositif représenté sur la figure 1.Other characteristics and advantages of the present invention will emerge from the description given below with reference to the appended drawing which illustrates an embodiment thereof devoid of any limiting character. On the drawing

En se référant au dessin on voit que le dispositif selon l'invention comporte essentiellement les composants ci-après
- une memoire stockant les informations relatives aux fréquences et aux canaux qui sont disponibles -dans les différentes zones géographiques ou l'utilisateur peut être amené à se trouver.Cette mémoire peut par exemple stocker les données cancernant les fréquences radio disponibles dans toutes les villes de France et plus particulièrement les fréquences FM. A titre d'exemples non limitatifs on peut utiliser une mémoire vive (RAM), une mémoire morte (RONv, une mémoire morte programmable électriquement (EPROM) ou une mémoire morte effaçable électriquement (EEPROM)
- un système de commande et de recherche, réalisé ici sous la forme d'un clavier electronîque 10, de type classique, sur lequel l'utilisateur frappe l'identité de la ville ou de la zone géographique dont il veut obtenir les fréquences ou canaux disponibles, cette information étant transmise a une unité de traitement qui recherche dans la mémoire, à partir de l'identité demandée par l'utilisateur quels sont ces canaux ou fréquences et,
- un systeme d'affichage 12 pouvant être, par exemple du type a diodes électroluminescentes (LED) ou à cristaux liquides (LCD) , sur lequel vient s'inscrire en dessous de la ville ou de la zone géographique désirée les noms des stations disponibles dans cette ville ou dans cette zone, avec l'indication des canaux et frequences correspondant.Referring to the drawing, it can be seen that the device according to the invention essentially comprises the following components
- a memory storing the information relating to the frequencies and the channels which are available - in the various geographical zones where the user can be brought to be. This memory can for example store the data damaging the radio frequencies available in all the cities of France and more particularly the FM frequencies. By way of nonlimiting examples, a random access memory (RAM), a read only memory (RONv, an electrically programmable read only memory (EPROM) or an electrically erasable read only memory (EEPROM) can be used.
a control and search system, produced here in the form of an electronic keyboard 10, of the conventional type, on which the user strikes the identity of the city or the geographical area from which he wants to obtain the frequencies or channels available, this information being transmitted to a processing unit which searches the memory, from the identity requested by the user, what these channels or frequencies are and,
a display system 12 which may be, for example of the light-emitting diode (LED) or liquid crystal (LCD) type, on which the names of the available stations are registered below the town or the desired geographical area in this city or in this zone, with the indication of the corresponding channels and frequencies.

Le dispositif est complété par des touches de commande classiques 14 interrupteur, entrée, suite, annulation, retour etc... The device is supplemented by conventional control keys 14 switch, entry, continuation, cancellation, return etc ...

Comme on le voit sur la figure 1 le dispositif. peut présenter l'aspect d'un boîtier de forme appropriée, pouvant être éventuellement intégré dans le tableau de bord d'un véhicule automobile et qui comporte en façade le système d'affichage 12, le clavier de commande 10 ainsi que les différentes touches 14. As seen in Figure 1 the device. may have the appearance of a box of suitable shape, which can optionally be integrated into the dashboard of a motor vehicle and which comprises the front display system 12, the control keyboard 10 and the various keys 14 .

Selon un mode de réalisation particulièrement avantageux, le dispositif comporte une interface assurant la connexion avec un récepteur radio afin de permettre une recherche et une reception automatique d'un canal ou d'une fréquence determinée, affiché sur le système d'affichage 12 et préalablement sélectionné par l'utilisateur à l'aide du clavier électronique 10.  According to a particularly advantageous embodiment, the device comprises an interface ensuring the connection with a radio receiver in order to allow an automatic search and reception of a channel or a determined frequency, displayed on the display system 12 and previously selected by the user using the electronic keyboard 10.

Le dispositif objet de la présente invention n'est bien entendu pas limité à l'application décrite et représentée ici mais il peut être réalisé selon diverses variantes. C'est ainsi que notamment ce dispositif peut être utilisé pour afficher des fréquences radio dans d'autres conditions, par exemple a domicile etc..  The device which is the subject of the present invention is of course not limited to the application described and shown here, but it can be produced according to various variants. Thus in particular this device can be used to display radio frequencies in other conditions, for example at home etc.
