Abstract
Description
Serrure électronique à changement de code périodique. electronic lock code changes periodically.
L'invention concerne une serrure électronique à code variable du type comprenant un émetteur d'un message codé et un récepteur dudit message formé de moyens de lecture dudit message reçu, de comparaison dudit message reçu-à un message contenu en mémoire et d'émission d'un signal de commande en cas de concordance entre lesdits messages. The invention relates to an electronic lock code variable of the type comprising a transmitter an encoded message and a receiver of said message formed reading means said received message, comparing said received message to a message content in memory and emission a control signal in case of agreement between said messages.
Une telle serrure électronique peut par exemple être utilisée comme télécommande d'accès à un véhicule automobile et/ ou d'utilisation de ce véhicule. Such an electronic lock can for example be used as a remote access to a motor vehicle and / or use of the vehicle.
Dans les serrures électroniques connues, le message codé est fixe, ce qui présente l'inconvénient majeur d'une reproduction relativement facile lorsque le message codé a été enregistré. In known electronic locks, the encoded message is fixed, which has the major relatively easy reproduction drawback when the encoded message has been recorded.
Pour pallier cet inconvénient, on a proposé de faire varier le code, par exemple à chaque utilisation, selon une loi plus ou moins aléatoire. To overcome this drawback, it is proposed to vary the code, for example, each use, according to a more or less random act. Cette variation de code entraîne des difficultés de synchronisation entre émetteur et récepteur et une complication de l'ensemble de la serrure électronique. This variation code causes difficulties of synchronization between transmitter and receiver and a complication of the entire electronic lock.
La présente invention vise à faire varier le code de maniere simple et sûre, afin d'augmenter considérablement la sécurité par rapport à un code fixe tout en limitant et simplifiant les problèmes de synchronisation entre émetteur et récepteur. The present invention aims to vary the code simple and safe manner, in order to greatly increase the security with respect to a fixed code while minimizing and simplifying the problems of synchronization between transmitter and receiver.
A cet effet, la serrure selon l'invention est caractérisée par le fait que le code varie en fonction du temps. To this end, the lock according to the invention is characterized in that the code varies over time.
Cette variation, commandée par une horloge, peut être aussi aléatoire qu'on le veut, afin d'augmenter la sécurité. This variation, controlled by a clock, can be as random as we want to increase safety.
De préférence, le récepteur et l'émetteur comprennent chacun un afficheur de temps avec remise à l'heure, le récepteur et l'émetteur comportant des moyens de modification respectivement du code conservé en mémoire et du code émis, les codes du récepteur et de l'émetteur étant identiques lorsque les temps affichés par chacun d'eux sont les mêmes. Preferably, the receiver and the transmitter each comprise a time display and release time, the receiver and transmitter having means for modifying each of the code stored in memory and transmitted code, the receiver codes and the transmitter being identical when the time displayed by each of them are the same.
Dans une forme de réalisation assurant une grande précision, les afficheurs de temps sont commandés par des oscillateurs à quartz ou des résonnateurs. In one embodiment providing highly accurate, time displays are controlled by crystal oscillators or resonators. De préférence, le circuit de commande comprend un microcalculateur, par exemple du type Preferably the control circuit comprises a microcomputer, for example of the type
CMOS. CMOS.
La sauvegarde de l'heure dans l'émetteur peut être assurée par un condensateur ou une mémoire non volatile. Saving time in the transmitter can be provided by a capacitor or a nonvolatile memory.
Pour l'émetteur, les défaillances ou débranchements de batterie pourront être assurés par un accumulateur électrique de faible capacité ou une mémoire non volatile. For the transmitter, malfunctions or battery disconnects may be operated by an electric accumulator of low capacity or a nonvolatile memory.
De préférence, le changement de code n'a pas lieu à heures fixes, mais selon une loi évitant le dépistage du système. Preferably, the code change does not take place at fixed times, but according to a law avoiding screening system.
Le message comprendra avantageusement un code indiquant l'heure, un code spécifique à chaque système, le code instantane et des bits de parité et de fin de message, le code spécifique déterminant l'évolution du code instantané en fonction du temps. The message advantageously comprise a code indicating the time, a code specific to each system, the instantaneous code and parity bits and end of message, the specific code determining the evolution of the instantaneous code in function of time.
De préférence, au moment du changement d'heure, le récepteur acceptera pendant un temps prédéterminé à la fois le code précédent et le nouveau code (pour palier à une légère désynchronisation des horloges). Preferably, at the time of the time change, the receiver will accept for a predetermined time at a time the previous code and the new code (to compensate for a slight desynchronization of clocks).
La programmation du code spécifique peut se faire par tous moyens connus, tels que liaisons sur circuit imprimé, coupures de pistes sur circuit imprimé, programmation d'une mémoire interne ou externe, roues codenses, etc. The programming specific code can be by any known means, such as connections PCB tracks outages PCB, programming an internal or external memory, codenses wheels, etc.
La programmation de l'heure peut se faire par afficheur analogique (figure 1), afficheur numérique (figure 2) ou par clavier (figure 3). The programming time can be done by analogue display (Figure 1), digital display (Figure 2) or keypad (Figure 3).
La figure 4 représente un schéma synoptique de la serrure électronique selon un exemple de réalisation de l'invention. 4 shows a block diagram of the electronic lock according to an exemplary embodiment of the invention.
L'émetteur 1 comprend un circuit de changement d'heure 2 et un circuit de changement de code spécifique 2' commandés par un calculateur 3 qui contrôle un afficheur de temps 4. The transmitter 1 includes a time shifting circuit 2 and a specific code changing circuit 2 'controlled by a computer 3 which controls a time display 4.
L'émetteur 1 comprend en outre un organe de transmission 5, par exemple par voie optique (infrarouge) ou radiofréquence, du contenu du calculateur 3. The transmitter 1 further comprises a transmission member 5, for example by optical means (infrared) or RF, the contents of the computer 3.
Le récepteur 6 comprend une section de réception des messages transmis par l'organe 5. Ces messages sont analysés dans un calculateur 7 qui commande une montre 8 pouvant servir de pendule de bord. The receiver 6 comprises a receiving section of the messages transmitted by the body 5. These messages are analyzed in a computer 7 that controls a clock 8 which can serve as clock edge. Le calculateur 7 reçoit par ailleurs un circuit de changement d'heure 9 et un circuit de changement de code spécifique 10. The computer 7 also receives a time changing circuit 9 and a specific code changing circuit 10.
Le signal de commande émis par le calculateur 7, en cas de concordance entre le message envoyé par l'organe de transmission 5 et le message qu'il contient, est envoyé à un interface de puissance 11 commandant alternativement le déverrouillage 12 et le verrouillage 13. The control signal issued by the computer 7, if a match between the message sent by the transmission member 5 and the message it contains, is supplied to a power interface 11 alternately commander unlocking the lock 12 and 13 .
Les calculateurs 3 et 7 peuvent être indifféremment soit des microprocesseurs, des circuits intégrés spécifiques, des circuits intégrés prediffusés ou des circuits précaractérisés. The computers 3 and 7 may equally be microprocessors, specific integrated circuits, integrated circuit gate arrays or standard cells circuits.
