Abstract

The invention relates to a secret code device with one or a hundred million combinations making it possible to remotely control the opening of a lock by infrared transmission. This device is constituted by a transmitter box 20 with 12 keys of which 10 are numbered from 0 to 9 and serve to enter the 6-figure code number of the lock to be opened; by a receiver 21 comprising a system for comparison 5 of the code received with that which has been assigned by the user 3. It supplies an item of information A in the event of agreement of the code received with that assigned. Furthermore, a time constant controlled by the key Y (validation) of the transmitter 20 reinitialises the system to 0 after 7 to 14 seconds. This system constitutes the safety feature of the assembly.

Description

L'invention concerne un dispositif de commande a distance a code secret;d'une serrure . Ce dispositif se compose, d'un récepteur infra-rouge à code secret incorporé à la fermeture de quelque sorte qu'elle soit. commandée électroniquement par rayon infra-rouge issu d'un émetteur de petites dimensions. The invention relates to a secret code remote control device for a lock. This device consists of an infrared receiver with secret code incorporated into the closure of any kind. electronically controlled by infrared ray from a small transmitter.

Le dispositif de commande du vérrouillage ne fait pas l'objet du présent brevet et diffère en fonction du type de vérroulllage utilisé.The locking control device is not the subject of this patent and differs according to the type of lock used.

On connaît des dispositifs utillsés dans l'industrie automobile ( voir brevet français n 7807726 du 17 mars 1978 et 8015239 du 9 Juillet 1980). dans ces dispositifs le message codé est incorporé dans l'émetteur une fois pour toute dans une mémoire comprenant un unique message ce message étant comparé à celui écrit également une fois pour toute dans le récepteur. Devices used in the automotive industry are known (see French patent No. 7807726 of March 17, 1978 and 8015239 of July 9, 1980). in these devices the coded message is incorporated into the transmitter once and for all in a memory comprising a single message, this message being compared with that also written once and for all in the receiver.

Cette réalisatlon présente l'inconvénient majeur en cas de perte de I'émet- teur d'y avoir incorporé l'unique code correspondant au récepteur, ce qui est préjudiciable à la sécurité du système. This implementation has the major drawback in the event of loss of the transmitter having incorporated therein the unique code corresponding to the receiver, which is detrimental to the security of the system.

La présente Invention vise à supprimer cet Inconvenlent majeur par l'incorporation du code uniquement dans le récepteur code qui peut d'ailleurs être changé facilement par l'utilisateur au cholx parml un mil(lon de combinaisons( 6 chiffres ).The present invention aims to eliminate this major disadvantage by incorporating the code only in the code receiver which can moreover be easily changed by the user to cholx parml one mil (lon of combinations (6 digits).

L'émetteur se présente sous la forme d'un boitier de petites dimensions comprenant 12 touches dont dix sont gravées de O à 9. il fonctionne avec une batterie standard de 9 volts, il comporte en outre un circuit intégré réalisant un code pour chaque chiffre et 2 transistors fournissant la puissance au circuit d'émission du signal. The transmitter is in the form of a small box comprising 12 keys, ten of which are engraved from 0 to 9. it operates with a standard 9-volt battery, it also has an integrated circuit producing a code for each digit and 2 transistors supplying power to the signal transmission circuit.

Le récepteur a pour fonction de reconnaître le code émis par l'émet- teur et de le cornparer à celui qui lui a été assigné par l'utilisateur. Lorsque tous les chiffres ont bien été reçus et dans le bon ordre un dispositif délivre une jnformation de commande de l'organe de vérroulllage o Tobtefois, au préalable la pression de la touche V (validation) de l'émetteur provoque dans le récepteur le démarrage d'une constante de temps variable de 7 à 14 secondes ( réglage interne par potentiomètre ) permettant la prise en compte du code secret, au bout de ce temps le systeme se réinitialise à 10 évitant ainsi toute récherche intempestive du code secret. The function of the receiver is to recognize the code transmitted by the transmitter and to compare it with the one assigned to it by the user. When all the figures have been received and in the correct order, a device delivers a command information from the locking member o Sometimes, before pressing the key V (validation) of the transmitter causes the receiver to start a variable time constant of 7 to 14 seconds (internal adjustment by potentiometer) allowing the secret code to be taken into account, at the end of this time the system resets to 10 thus avoiding any untimely retrieval of the secret code.

L'invention sera bien comprise à la lecture de la description suivante faite en se référant aux schémas annexés l'exemple est donné pour un code secret à 6 chîffres.La figure 1 illustre le schéma de l'émetteur : le circuit intégré (11) est un circuit servant au codage,à chaque chiffre du clavier (12) correspond donc une forme d'onde bien déterminée, emise en (13) par des diodes infra-rouges. The invention will be clearly understood on reading the following description made with reference to the attached diagrams the example is given for a secret code with 6 digits. FIG. 1 illustrates the diagram of the transmitter: the integrated circuit (11) is a circuit used for coding, each digit of the keyboard (12) therefore corresponds to a well-defined waveform, emitted at (13) by infrared diodes.

La figure 2 illustre le schéma du récepteur. Les circuits (1) et (2) servent respectivement à la réception et au décodage des signaux reçus de l'émetteur (20).Figure 2 illustrates the diagram of the receiver. The circuits (1) and (2) are used respectively for receiving and decoding the signals received from the transmitter (20).

Le numéro de code secret est programmé à l'aide de 6 commutateurs (3) codés BCD à 110 positions.The secret code number is programmed using 6 switches (3) coded BCD with 110 positions.

Chaque entrée de ces commutateurs est reliée à un compteur d'impulsion (4). Le circuit (5) qui est un comparateur 4 bits qui compare l'information reçue du décodeur (2) à celle du premier commutateur (3) (l'entrée de celui-ci étant à l'état 1 les autres à 0 ) si il y a concordance entre les deux informations le circuit (5) délivre sur sa sortie une information qui va incrementer (avance sur le schéma ) d' un pas le compteur (4) ce sera alors l'entrée du deuxième commutateur qui sera alimenté, lorsque le sixième chiffre est bon l'état 1 de l'entrée du sixième commutateur (3) saute d'uncran sur le compteur (4) la sortie nos de ce meme compteur passe à l'état 1 et déclenche un monostable (6) qui va délivrer pendant à peu près 5 secondes une information sur la sortie A du schéma pour commander l'organne de vérrouillage au même instant le compteur est remis à zéro par la sortie complémentaire du circuit (6) ligne RAZ du schéma. Each input of these switches is connected to a pulse counter (4). The circuit (5) which is a 4-bit comparator which compares the information received from the decoder (2) with that of the first switch (3) (the input thereof being at state 1 the others at 0) if there is a concordance between the two pieces of information the circuit (5) delivers on its output information which will increment (advance on the diagram) by one step the counter (4) it will then be the input of the second switch which will be supplied, when the sixth digit is good state 1 of the input of the sixth switch (3) jumps from one screen to the counter (4) the output nos of this same counter goes to state 1 and triggers a monostable (6) which will deliver for about 5 seconds information on the output A of the diagram for controlling the locking member at the same instant the counter is reset to zero by the complementary output of the circuit (6) line RESET of the diagram.

La securite est assurée par la lettre "V" frappé sur le clavier. Elle sert a valider le système. Cette lettre est décodée séparément (7) (sortie validation du schéma ) et déclenche le deuxième monostable contenu dans le boitier (63. La sortie (8) passe à 0 et donne par l'intermédiaire de la ligne RAZ la possibilité au compteur de compter, il ne peut le faire que pendant la durée de la constante de temps soit entre 7 et 14 secondes (réglable), temps au bout duquel la ligne de FIAZ se retrouve à l'état 1, ce qui bloque le compteur. II y a donc une infime chance de trouver le chiffre mis en mémoire parmi 1 million en moins d'une dizaine de secondes.Security is assured by the letter "V" struck on the keyboard. It is used to validate the system. This letter is decoded separately (7) (output validation of the diagram) and triggers the second monostable contained in the box (63. The output (8) goes to 0 and gives via the line RESET the possibility to the counter to count , it can only do so during the duration of the time constant, between 7 and 14 seconds (adjustable), time after which the FIAZ line is in state 1, which blocks the counter. therefore a tiny chance of finding the figure stored in memory among 1 million in less than ten seconds.

L'adjonction ou lue retrait de commutateurs peu augmenter ou diminuer le nombre de combinaisons du code secret le maximum pouvant être 8 chiffres soit à une unité près 100 millions de combinaisons.  The addition or reading of switches can increase or decrease the number of combinations of the secret code, the maximum being 8 digits, or to one unit by 100 million combinations.
