Description

La présente invention concerne les dispositifs électroniques de manoeuvre dont l'actionnement est obtenu au moyen d'un code et qui sont destinés à commander un appareil controlant un accès,tels qu'une serrure à gâche électrique ou un moteur d'ouverture de porte de manière à ne permettre l'accès qu'aux personnes autorisées connaissant ledit code, Généralement, ces dispositifs électroniques de manoeuvre comportent d'une part une unité de commande disposée au voisinage de l'appareil à commander et qui comprend un dispositif électronique qui vérifie le code fourni par les utilisateurs et fournit en cas de code correct un signal de commande du dispositif électrique d'actionnement de l'appareil et, d'autre part, une unité de surveillance disposée à distance et qui permet de commander et/ou de contrôler ledit accès.The present invention relates to electronic operating devices, the actuation of which is obtained by means of a code and which are intended to control an apparatus controlling access, such as an electric strike lock or a door opening motor. so as to allow access only to authorized persons knowing said code, Generally, these electronic operating devices comprise on the one hand a control unit arranged in the vicinity of the device to be controlled and which comprises an electronic device which checks the code supplied by the users and provides, if the code is correct, a control signal for the electrical device actuating device and, on the other hand, a monitoring unit arranged remotely and which makes it possible to command and / or control said access.

De tels dispositifs sont constitués par exemple par les serrures commandées par un code qui sont destinées en particulier à la commande de l'ouverture des chambres d'un hotel ou d'un motel et comportent une unité de codage qui est disposée à distance de la porte à commander, par exemple au bureau de l'hotel, et qui comprend un dispositif de codage à distance, relié à l'unité de commande. Une telle gâche électrique est décrite en particulier dans le brevet français 2 224 629; le dispositif de codage à distance permet de modifier à volonté le code d'ouverture de chaque porte à partir du bureau de l'hotel. Ceci nécessite donc que chaque client vienne coder la porte de sa chambre au bureau de l'hotel, ce qui constitue une contrainte, en particulier dans le cas de motel; de plus, le client est souvent obligé de composer son code en présence du personnel de l'hotel et il n'est pas assuré que son code soit vraiment confidentiel.Such devices are constituted for example by locks controlled by a code which are intended in particular for controlling the opening of the rooms of a hotel or a motel and include a coding unit which is arranged at a distance from the door to be controlled, for example at the hotel office, and which includes a remote coding device, connected to the control unit. Such an electric strike is described in particular in French patent 2,224,629; the remote coding device allows you to change the opening code of each door at will from the hotel office. This therefore requires that each client come to code the door to their room at the hotel office, which constitutes a constraint, in particular in the case of a motel; in addition, the customer is often obliged to dial his code in the presence of hotel staff and there is no guarantee that his code is truly confidential.

L'invention a donc pour objet un dispositif de commande électromécanique commandé par un code puvant être modifié à distance du type précité qui permet le codage "sur place" par l'utilisateur. De ce fait, dans le cas d'un hotel, le client peut composer de sa chambre son code d'ouverture qu'il sera seul à connaître pendant toute la durée de son séjour, le personnel de l'hotel pouvant remettre son propre code à la fin du séjour du client.The invention therefore relates to an electromechanical control device controlled by a code that can be modified remotely of the aforementioned type which allows coding "on the spot" by the user. Therefore, in the case of a hotel, the customer can dial his room code of opening which he will be the only one to know for the duration of his stay, the hotel staff being able to give his own code at the end of the customer's stay.

Le dispositif électromécanique de manoeuvre selon l'invention est notamment remarquable en ce que l'unité de commande précitée comporte en outre, un dispositif sélecteur commandé par l'unité de codage à distance et qui transmet de manière sélective à la mémoire un code fourni par l'interface d'entrée ou envoyé par l'unité de codage. Avantageusement, l'unité de commande comprend un multiplexeur recevant d'une part la sortie de l'interface d'entrée, et d'autre part, le code envoyé par l'unité de codage, la sortie du multiplexeur étant envoyée sur l'entrée d'écriture de la mémoire et ledit multiplexeur étant commandé à partir de l'unité de codage à distance.The electromechanical operating device according to the invention is notably remarkable in that the aforementioned control unit further comprises a selector device controlled by the remote coding unit and which selectively transmits to the memory a code supplied by the input interface or sent by the coding unit. Advantageously, the control unit comprises a multiplexer receiving on the one hand the output of the input interface, and on the other hand, the code sent by the coding unit, the output of the multiplexer being sent to the memory write input and said multiplexer being controlled from the remote coding unit.

Selon une autre caractéristique de l'invention, l'unité de commande comporte un circuit logique OU recevant d'une part un signal indiquant la fourniture d'un chiffre de code par l'interface d'entrée,et d'autre part, un ordre de codage à distance et dont la sortie est reliée au port de commande d'écriture de la mémoire.According to another characteristic of the invention, the control unit comprises an OR logic circuit receiving on the one hand a signal indicating the supply of a code digit by the input interface, and on the other hand, a remote coding order and the output of which is connected to the memory write command port.

Selon encore une autre caractéristique de l'invention, l'unité centrale comporte un dispositif de comptage des chiffres de code fournis par l'interface d'entrée, la sortie dudit compteur étant reliée à un limiteur du nombre de chiffres du code qui commande la remise à zéro dudit compteur de chiffres d'entrée pour un nombre prédéterminé de chiffres de code fournis par ledit interface. La sortie dudit limiteur est reliée d'une part à un compteur de codesd'entrée, et, d'autre part, à un circuit de temporisation et l'unité de commande comporte un circuit logique ET recevant d'une part la sortie dudit circuit de temporisation et, d'autre part, un signal correspondant à un nombre de codes prédéterminé, la sortie dudit circuit logique ET fournissant une alarme de faux codes.According to yet another characteristic of the invention, the central unit comprises a device for counting the code digits supplied by the input interface, the output of said counter being connected to a limiter of the number of digits of the code which controls the resetting said input digit counter to a predetermined number of code digits supplied by said interface. The output of said limiter is connected on the one hand to an input code counter, and, on the other hand, to a timing circuit and the control unit comprises an AND logic circuit receiving on the one hand the output of said circuit time delay and, on the other hand, a signal corresponding to a predetermined number of codes, the output of said logic circuit AND providing an alarm of false codes.

D'autres caractéristiques et avantages de l'invention ressortiront de la description qui suit d'un exemple de réalisation ainsi que des dessins annexés sur lesquels :

  • - la Fig. 1 représente sous forme d'un schéma synoptique une serrure à gâche électrique conforme à la présente invention et,
  • - la Fig. 2 représente un détail du schéma de la figure 1.
Other characteristics and advantages of the invention will emerge from the description which follows of an exemplary embodiment as well as from the appended drawings in which:
  • - Fig. 1 shows in the form of a block diagram an electric strike lock according to the present invention and,
  • - Fig. 2 shows a detail of the diagram in FIG. 1.

La figure 1 représente l'unité de commande de la gâche octrique qui comporte un interface d'entrée constitué lecteur de code 1, par exemple un clavier, un lecteur de code optique, magnétique ou infra-rouge suivi d'un codeur binaire 2 dont la sortie est envoyée sur l'une des entrées d'un comparateur 3 qui reçoit sur son autre entrée le contenu d'une mémoire 4, La sortie du comparateur 3 commande par l'intermédiaire d'une logique de comparaison qui sera décrite plus loin, le dispositif électrique 5 d'ouverture de la gâche électrique.Figure 1 shows the control unit of the octagonal door release which has an input interface consisting code reader 1, for example a keyboard, an optical, magnetic or infrared code reader followed by a binary coder 2 whose output is sent to one of the inputs of a comparator 3 which receives on its other input the content of a memory 4, The output of the comparator 3 controls, via a comparison logic which will be described later, the electrical device 5 for opening the electric strike.

La serrure à gâche électrique comporte également une unité de codage disposée à distance et qui envoie d'une part sur la ligne 6 un ordre de codage à distance et d'autre part sur la ligne 7 des impulsions de codage; ces deux lignes sont reliées auxports d'entrée d'un circuit logique ET 8 qui commande une horloge 9 suivied'un compteur 11 dont. le contenu est envoyé sur le port d'entrée d'écriture de la mémoire 4.The electric strike lock also comprises a coding unit arranged remotely and which sends on the one hand on line 6 a remote coding order and on the other hand on line 7 coding pulses; these two lines are connected to the input ports of an AND logic circuit 8 which controls a clock 9 followed by a counter 11 of which. the content is sent to the write input port of memory 4.

Conformément à l'invention, l'unité de commande comporte un sélecteur commandé par l'unité de codage et qui permet d'envoyer de manière sélective à la mémoire 4, soit le code fourni par le codeur 2 branché à la sortie de l'interface 1, soit le code fourni par le compteur 11. Ce dispositif sélecteur comprend essentiellement un multiplexeur 12 commandé depuis l'unité de codage par l'intermédiaire d'une ligne 13 et qui reçoit d'une part la sortie du codeur 2, et d'autre part la sortie du compteur 11, la sortie du multiplexeur 12 étant envoyée dans le port d'entrée d'écriture de la mémoire 4. Un circuit logique OU 14 reçoit d'une part un signal correspondant à un codage à distance, à savoir la sortie du circuit logique 8 et, d'autre part, un signal correspondant à un codage sur le clavier 1, ledit signal étant fourni par le codeur 2; la sortie de ce circuit logique OU 14 est envoyée sur le port de commande d'écriture de la mémoire 4.According to the invention, the control unit comprises a selector controlled by the coding unit and which makes it possible to send selectively to memory 4, that is to say the code supplied by the coder 2 connected to the output of the interface 1, ie the code supplied by the counter 11. This selector device essentially comprises a multiplexer 12 controlled from the coding unit via a line 13 and which receives on the one hand the output of the coder 2, and on the other hand, the output of the counter 11, the output of the multiplexer 12 being sent to the write input port of the memory 4. An OR logic circuit 14 receives on the one hand a signal corresponding to a remote coding, namely the output of the logic circuit 8 and, on the other hand, a signal corresponding to a coding on the keyboard 1, said signal being supplied by the coder 2; the output of this OR logic circuit 14 is sent to the write control port of memory 4.

La sortie du circuit logique 8 est envoyée par ailleurs sur un compteur du nombre de créneaux d'entrée 10 dont la sortie est envoyée sur un multiplexeur 15. Un compteur de chiffres entrés 16 est branché à la sortie du codeur 2; la sortie de ce compteur est envoyée d'une part à un circuit limiteur du nombre de chiffres du code 17, et, d'autre part, à la deuxième entrée du multiplexeur 15. La remise à zéro du compteur 16 est commandée par le limiteur 17.The output of the logic circuit 8 is also sent to a counter for the number of input slots 10, the output of which is sent to a multiplexer 15. An input digit counter 16 is connected to the output of the encoder 2; the output of this counter is sent on the one hand to a circuit limiting the number of digits of the code 17, and, on the other hand, to the second input of the multiplexer 15. The resetting of the counter 16 is controlled by the limiter 17.

La logique de comparaison citée plus haut qui est commandée par le comparateur 3 est constituée par un compteur du nombre de chiffres corrects 18 suivi d'un comparateur 19 du nombre de chiffres corrects au nombre du limiteur de chiffres 17. La sortie du comparateur 19 commande la gâche électrique proprement dite 5 par l'intermédiaire d'un circuit logique OU 20 qui peut recevoir par ailleurs un ordre de commande d'ouverture provenant d'unité de codage par une ligne 21. Dans ce cas, le signal de ligne 21 peut être une fonction ET entre une validation de l'unité de codage et un signal provenant d'un interrupteur ou bouton poussoir quelconque fixé à proximité du clavier. Cette fonction dl"entrée libre" permet d'actionner l'électromécanisme 5 sans pour autant être obligé de fournir un code au comparateur 3.The comparison logic mentioned above which is controlled by the comparator 3 consists of a counter of the number of correct digits 18 followed by a comparator 19 of the number of correct digits to the number of the digit limiter 17. The output of the comparator 19 commands the electric strike proper 5 via an OR logic circuit 20 which can also receive an opening command from the coding unit via a line 21. In this case, the line signal 21 can be an AND function between a validation of the coding unit and a signal coming from any switch or push button fixed near the keyboard. This function of the "free entry" used to operate the electromechanism 5 without having to provide a code to Compare 3.

Le clavier 1 comprend une touche de remise à zéro R qui actionne d'une part un interrupteur temporisé 22 de l'éclairage 23 du clavier, et d'autre part, la remise à zéro du compteur 16 de nombre de chiffres entrés et du compteur 18 du nombre de chiffres corrects.The keyboard 1 comprises a reset key R which actuates on the one hand a timed switch 22 of the lighting 23 of the keyboard, and on the other hand, the reset of the counter 16 of the number of digits entered and of the counter 18 of the number of correct digits.

La figure 2 représente un mode de réalisation du circuit limiteur du nombre de chiffres tel que le circuit 17. Sur cette figure, on voit le compteur 16 de nombre de chiffres d'entrée qui comportent le port de sortie correspondant aux quatre bits de codage binaires qui sont envoyés sur le multiplexeur 15. Pour limiteur le nombre de chiffres d'entrée, on envoie sur un circuit logique ET 34 deux de ces sorties du compteur 16 ou l'une d'entre elles sur les deux entrée du circuit ET 34, et la sortie de ce circuit ET 34 étant envoyée sur le port de remise à zéro du compteur 16 par l'intermédiaire d'un deuxième circuit logique ET 35 recevant par ailleurs le circuit de remise à zéro provenant de l'actionnement de la touche de remise à zéro du clavier 1 ou d'un signal équivalent d'un lecteur quelconque de code. Dans l'exemple représenté, ces circuits ET sont en fait des circuits NON-ET. Grace au circuit 34, on peut limiter le nombre de chiffres entrés à tout nombre binaire comprenant un ou deux bits égaux à 1, c'est-à-dire aux nombres décimaux 1,2,3,4,5,.6,8,9,10,12 et 16. Selon une caractéristique de l'invention, on prévoit un dispositif permettant d'engerdrer une alarme de "faux codes" lorsqu'un nombre prédéterminé de codes sont composés sur le clavier 1. Ce dispositif comprend une temporisation 24 et un compteur 25 de codes d'entrées; le déclenchement de la temporisation 24 est commandée par le circuit 17 limiteur du nombre de chiffres du code dont les impulsions de sortie sont comptées par le compteur 25. La sortie de la temporisation 24 et du compteur de code d'entrée 25 sont envoyées sur une porte logique ET 26 dont la sortie constitue le signal de faux codes. Le compteur 25 de faux codes est remis à zéro à la fin du signal temporisé fourni par la temporisation 24; par ailleurs la temporisation 24 est inhibée par le signal de commande d'ouverture de la gâche électrique fourni par la porte logique OU 20.FIG. 2 represents an embodiment of the circuit limiting the number of digits such as circuit 17. In this figure, we see the counter 16 for the number of input digits which comprise the output port corresponding to the four binary coding bits which are sent to the multiplexer 15. To limit the number of input digits, two of these outputs of the counter 16 or one of them are sent to an AND logic circuit 34, and the output of this AND circuit 34 being sent to the reset port of the counter 16 via a second AND logic circuit 35 also receiving the reset circuit coming from the actuation of the key. reset keyboard 1 or an equivalent signal from any code reader. In the example shown, these AND circuits are in fact NAND circuits. Thanks to the circuit 34, it may limit the number of digits entered at any binary number comprising one or two bits equal to 1, is to say that the decimal numbers 1,2,3,4,5,. 6,8,9,10,12 and 16. According to a characteristic of the invention, there is provided a device making it possible to record an alarm of "false codes" when a predetermined number of codes are dialed on the keyboard 1. This device includes a timer 24 and a counter 25 for entry codes; the triggering of timer 24 is controlled by circuit 17 limiting the number of digits of the code whose output pulses are counted by counter 25. The output of timer 24 and the input code counter 25 are sent on a AND logic gate 26, the output of which constitutes the false code signal. The counter 25 of false codes is reset to zero at the end of the timed signal supplied by the timer 24; moreover, the time delay 24 is inhibited by the command signal to open the electric strike supplied by the OR logic gate 20.

Le fonctionnement de la serrure à gâche électrique qui vient d'être décrite est le suivant.The operation of the electric strike lock which has just been described is as follows.

Les utilisateurs qui connaissent le code d'ouverture frappent d'abord la touche de remise à zéro R du clavier 1, ce qui entraine l'allumage du voyant 23 d'éclairage du clavier. L'actionnement de cette touche R remet également à zéro le compteur 16 de chiffres entrés, ceci permettant l'initialisation du système, et le compteur 18 du nombre de chiffres corrects. A chaque fois que l'utilisateur frappe un des chiffres -du code sur le clavier 1, ce chiffre est mis sous forme binaire dans le codeur 2 et le comparateur 3 effectue la comparaison entre ce chiffre et celui que lui fournit la mémoire 4. A chaque fois qu'il y a coïncidence entre ces deux chiffres, le comparateur 3 commande le compteur 18; lorsque le nombre de chiffres corrects successif comptés par le compteur 18 correspond au nombre affiché dans le limiteur 19, c'est-à-dire au nombre de chiffres du code, ce circuit limiteur commande l'alimentation de la gâche électrique 5 par l'intermédiaire de la porte OU 20. Si les deux chiffres envoyés au comparateur 3 ne sont pas égaux, la sortie du comparateur commande la remise à zéro du compteur 18 de chiffres corrects par exemple par l'intermédiaire d'une porte inverseuse 27. On voit que la porte logique OU 20 ne délivre de signal de validation que si l'on a composé successivement tous les chiffres du code dans un ordre prédéterminé.Users who know the opening code first hit the reset key R on the keyboard 1, which causes the indicator light 23 on the keyboard to come on. Pressing this R key also resets the counter 16 of entered digits to zero, this allowing the system to be initialized, and the counter 18 of the number of correct digits. Each time the user enters one of the digits of the code on the keyboard 1, this digit is put in binary form in the encoder 2 and the comparator 3 compares this digit with that provided by the memory 4. A each time there is a coincidence between these two digits, the comparator 3 controls the counter 18; when the number of successive correct digits counted by the counter 18 corresponds to the number displayed in the limiter 19, that is to say to the number of digits of the code, this limiter circuit controls the supply of the electric strike 5 by the intermediate of the OR gate 20. If the two digits sent to the comparator 3 are not equal, the output of the comparator commands the reset of the counter 18 of correct digits, for example by means of an inverting gate 27. We see that the OR logic gate 20 only delivers a validation signal if all the digits of the code have been successively dialed in a predetermined order.

La modification à distance du code contenu dans la mémoire 4 s'effectue par l'envoi d'un ordre continu de commande à distance sur la ligne 6 alors que des créneaux de largeur variable sont envoyés sur la ligne 7. La coincidence de ces créneaux avec l'ordre de codage à distance commande, par l'in- l'intermédiaire de la porte ET 8, l'envoi d'impulsions fournies par l'horloge 9 au compteur 11 qui compte ces impulsions et transmet le chiffre correspondant au multiplexeur 12. Le signal de codage à distance fourni par la ligne 13 commande le multiplexeur de manière que ce dernier écrive le chiffre précité dans la mémoire 4.The remote modification of the code contained in the memory 4 is carried out by sending a continuous remote control command on line 6 while slots of variable width are sent on line 7. The coincidence of these slots with remote coding order command, by the- via the AND gate 8, the sending of pulses supplied by the clock 9 to the counter 11 which counts these pulses and transmits the digit corresponding to the multiplexer 12. The remote coding signal supplied by the line 13 controls the multiplexer so that the latter writes the aforementioned digit in memory 4.

Le compteur de créneaux 10 compte les créneaux envoyés par la ligne 7, c'est-à-dire en fait leschiffresde codage envoyés; la sortie de ce compteur est envoyé sur le multiplexeur 15 et la commande de codage à distance fournie par la ligne 13 agit sur le multiplexeur 15 de manière que ce dernier modifie l'adresse de la mémoire 4 en fonction du nombre de créneaux comptés par le compteur 10.The slot counter 10 counts the slots sent by line 7, that is to say in fact the coding figures sent; the output of this counter is sent to the multiplexer 15 and the remote coding command provided by the line 13 acts on the multiplexer 15 so that the latter modifies the address of the memory 4 according to the number of slots counted by the counter 10.

Lorsque l'on désire effectuer le codage de la mémoire 4 par le clavier 1, ce qui permet à l'utilisateur d'enregistrer le code de son choix sans avoir à se déplacer jusqu'au poste de codage à distance, un signal correspondant est envoyé sur la ligne 13 de commande de codage interne, ce qui place les mul- tiplexeurs 12 et 15 dans l'état où ils laissent passer vers la mémoire 4 respectivement le chiffre binaire fourni par le codeur 2 et le nombre de chiffres entrés fourni par le compteur 16. Le processus de chargement de la mémoire 4 et son adressage se produisent de manière analogue au processus de codage à distance. Dans les deux cas, l'écriture en mémoire est commandée par le circuit logique OU 14 qui reçoit soit l'impulsion fournie par la porte logique 8 et correspondant au créneau de codage envoyé par la ligne 7, soit le signal fourni par le codeur 2 et indiquant l'envoi d'un chiffre par le clavier 1.When it is desired to carry out the coding of the memory 4 by the keyboard 1, which allows the user to record the code of his choice without having to move to the remote coding station, a corresponding signal is sent to the internal coding command line 13, which places the multiplexers 12 and 15 in the state where they allow the binary digit supplied by the coder 2 and the number of input digits supplied by the memory to pass through respectively to memory 4 the counter 16. The process of loading the memory 4 and its addressing takes place in a manner analogous to the process of remote coding. In both cases, writing to memory is controlled by the OR logic circuit 14 which receives either the pulse supplied by the logic gate 8 and corresponding to the coding slot sent by the line 7, or the signal supplied by the encoder 2 and indicating that a number has been sent via the keyboard 1.

On voit que l'invention permet de réaliser l'enregistrement d'un code d'ouverture dans la mémoire 4 indifféremment à partir du clavier 1 ou à partir de l'unité de codage à distance, de laquelle proviennent les lignes 6,7,13 et 21. Le codage à distance ou local est à chaque fois effectué sous le contrôle de l'unité de codage qui envoie les ordres correspondants.It can be seen that the invention makes it possible to record an opening code in the memory 4 either from the keyboard 1 or from the remote coding unit, from which the lines 6,7, 13 and 21. The remote or local coding is each time carried out under the control of the coding unit which sends the corresponding orders.

Selon une autre caractéristique importante.¿e l'invention, on engendre un signal d'alarme de faux codes, lorsqu'un certain nombre de faux codes sont composés sur le clavier pendant une période prédéterminée. Ceci est obtenu de la manière suivante; à chaque fois que le circuit limiteur du nombre de chiffres entrés 17 enregistre un nombre de chiffres entrés égal au nombre de chiffres du code, non seulement il remet à zéro le compteur 16 de chiffres entrés mais il commande le circuit de temporisation 24 de manière à lancer une temporisation égale par exemple à 30 secondes. Ce circuit limiteur 17 envoie également une impulsion sur le compteur 25 de codes entrés qui fournit un signal au circuit logique ET 26 lorsqu'il a compté un nombre prédéterminé de codes entrés. Par exemple on peut relier l'un des ports d'entrée du circuit ET 26 à la sortie du compteur 25 correspondant au bit de poids le plus élevé, à savoir 8; dans ce cas, à chaque fois que le compteur 25 compte huit codes entrées, il envoie un signal sur le circuit ET 26. Ce dernier circuit ET reçoit par ailleurs le signal temporisé fourni par la temporisation 24 de telle manière que si ce nombre prédéterminé de codes a été effectué pendant la durée du signal temporisé, on obtient à la sortie du circuit ET 26 un signal d'alarme de faux codes qui peut être ensuite mémorisé et envoyé à l'unité de codage à distance. Cette alarme est de préférence réalisée de manière discrète de manière que le personnel présent auprès de l'unité de codage à distance soit seul prévenu de ces tentatives d'ouverture de la porte. Pour éviter l'émission d'un signal de faux codes lorsqu'un utilisateur autorisé compose le code correct juste après qu'une personne aie tenté de forcer la serrure en essayant plusieurs codes, le signal d'ouverture fourni par le circuit OU 20 inhibe le signal temporisé du circuit de temporisation 24; ce circuit. permet également d'effectuer une remise à zéro du dispositif générateur de signal d'alarme de faux codes après que la - porte ait été ouverte par une personne autorisée. A la fin du signal temporisé, le compteur 25 est remis à zéro par le circuit de temporisation 24.According to another important characteristic. The invention generates a false code alarm signal, when a certain number of false codes are dialed on the keyboard during a predetermined period. This is achieved in the following manner; each time the circuit limiting the number of digits entered 17 records a number of digits entered equal to the number of digits in the code, not only does it reset the counter 16 of digits entered but it controls the timing circuit 24 so as to start a time delay of 30 seconds, for example. This limiter circuit 17 also sends a pulse to the counter 25 for input codes which supplies a signal to the AND logic circuit 26 when it has counted a predetermined number of input codes. For example, one of the input ports of the AND circuit 26 can be connected to the output of the counter 25 corresponding to the most significant bit, namely 8; in this case, each time the counter 25 has eight input codes, it sends a signal to the AND circuit 26. This latter AND circuit also receives the timed signal supplied by the timer 24 so that if this predetermined number of codes was carried out for the duration of the timed signal, a false code alarm signal is obtained at the output of circuit ET 26 which can then be memorized and sent to the remote coding unit. This alarm is preferably carried out discreetly so that the personnel present at the remote coding unit is the only one informed of these attempts to open the door. To avoid issuing a false code signal when an authorized user dials the correct code immediately after a person has tried to force the lock by trying several codes, the opening signal provided by the OR circuit 20 inhibits the timed signal of the timing circuit 24; this circuit. also allows resetting of the false code alarm signal generating device after the - door has been opened by an authorized person. At the end of the delayed signal, the counter 25 is reset to zero by the delay circuit 24.

Selon une autre possibilité de l'invention, on prévoit que la détection d'un faux code entraîne le blocage de l'organe de saisie c'est-à-dire le clavier en l'occurence, pendant une période déterminée; cette période peut être doublée à chaque fois que l'on détecte un nouveau faux code. Ainsi, par exemple, on peut prévoir qu'après l'entrée d'un faux code, le clavier est bloqué pendant 10 secondes puis pendant 20 secondes à la suite d'un deuxième faux code, puis pendant 40 secondes à la suite d'un troisième faux code et ainsi de suite. De ce fait, le temps nécessaire pour essayer un nombre élevé de code par une personne non autorisée augmente très rapidement et on élimine pratiquement cette possibilité de tentative de composer de nombreux codes pour obtenir par hasard le code réel.According to another possibility of the invention, provision is made for the detection of a false code to result in the blocking of the input device, that is to say the keyboard in this case, for a determined period; this period can be doubled each time a new false code is detected. Thus, for example, it can be provided that after entering a false code, the keyboard is blocked for 10 seconds then for 20 seconds following a second false code, then for 40 seconds following a third false code and so on. As a result, the time required to try a high number of code by an unauthorized person increases very quickly and this possibility of attempting to compose numerous codes to obtain the real code by chance is practically eliminated.

On voit également que l'on peut donc obtenir une alarme discrète dans le cas où il y a une tentative de fraude de l'ouverture (chocs ou arrachements, sur le clavier ou la porte)..We also see that we can therefore obtain a discreet alarm in the event that there is an attempt to defraud the opening (knocks or tears, on the keyboard or the door).

La description ci-dessus d'un exemple de réalisation n'a été fournie qu'à titre illustratif et nullement limitatif et il est évident que l'on peut y apporter des modifications ou variantes sans pour autant sortir du cadre de la présente invention. En particulier, les composants du schéma de la figure 1 peuvent être remplacés par des composants effectuant la même fonction, plus particulièrement, le clavier 1 peut être remplacé par n'importe quel type de périphérique capable de générer un code (lecteur de code optique, magnétique à barre, à infra-rouge, à hyper-fréquence,...).The above description of an exemplary embodiment has been provided for illustration only and is in no way limitative and it is obvious that modifications or variants can be made without departing from the scope of the present invention. In particular, the components of the diagram in FIG. 1 can be replaced by components performing the same function, more particularly, the keyboard 1 can be replaced by any type of device capable of generating a code (optical code reader, magnetic bar, infrared, hyper-frequency, ...).

Il est à remarquer que tous les signaux d'alarme devant être transmis à l'unité de codage sont à sécurité positive, l'état logique normal au repos, sans alarme étant un. De ce fait, toute rupture du câble de transmission entraîne une alarme.It should be noted that all the alarm signals to be transmitted to the coding unit are positive safety, the normal logic state at rest, without alarm being one. Therefore, any break in the transmission cable causes an alarm.

Parmi les divers signaux d'alarme, on peut prévoir la reconnaissance d'alarme due à une entrée sous contrainte ainsi que celle due à une tentative d'ouverture de la porte par la mise sous tension extérieure de l'électromécanisme.Among the various alarm signals, it is possible to provide for the recognition of alarms due to an entry under stress as well as that due to an attempt to open the door by energizing the electromechanism externally.

La mémoire 4 décrite est du type à entrée parallèle mais il est évident que l'on peut utiliser une mémoire vive non volatile de manière à conserver le code en cas de suppression de la tension d'alimentation sinon il serait alors impossible d'obtenir l'ouverture. Dans ce cas il s'agit alors d'une mémoire à entrée série et non pas parallèle.The memory 4 described is of the parallel input type but it is obvious that a non-random access memory can be used volatile so as to keep the code in the event of removal of the supply voltage, otherwise it would be impossible to obtain the opening. In this case it is then a memory with serial input and not parallel.
