Abstract

The invention relates to the field of electrically programmable coded locks and keys. The lock, initially uncoded, directly receives its opening code in its main memory via a transponder, from the key bearing a code. A second memory, annexed to the main memory, commands the key to memorise the opening code, and is then erased by the lock command. The invention is useful particularly in controlling access to tenament blocks.

Description

DISPOSITIF DE CONTROLE D'ACCES POUR PORTE A SERRURE ELECTRONIQUE PROGRAMMABLEACCESS CONTROL DEVICE FOR A PROGRAMMABLE ELECTRONIC LOCK DOOR
La présente invention se rapporte au domaine de la serrurerie, et particulièrement à celui des serrures à clé électronique dites « sans contact ».The present invention relates to the field of locksmithing, and particularly to that of electronic key locks called "contactless".
D'une façon générale, une serrure est un appareil de fermeture comportant une partie mobile, ou pêne, pouvant pénétrer dans une partie fixe ou gâche, la pénétration étant commandée par un élément amovible ou clé, introduit dans un logement de la partie mobile. Lorsqu'on désire conserver secrète la possibilité d'ouverture, la clé agit habituellement par action de régions en relief ou en creux, coopérant avec des régions complémentaires solidaires du pêne, ces régions étant arbitrairement conçues pour coopérer suivant un codage mécanique déterminé, en vue d'autoriser l'ouverture ou la fermeture de la serrure.Generally, a lock is a closing device comprising a movable part, or bolt, which can penetrate into a fixed or keeper part, penetration being controlled by a removable or key element, introduced into a housing of the movable part. When it is desired to keep the possibility of opening secret, the key usually acts by the action of raised or hollow regions, cooperating with complementary regions integral with the bolt, these regions being arbitrarily designed to cooperate according to a determined mechanical coding, with a view to authorize the opening or closing of the lock.
Dans le domaine concerné, il est connu de faire appel, à la place d'un codage mécanique mettant an oeuvre des régions géométriquement complémentaires à un codage électrique.In the field concerned, it is known practice to use, instead of mechanical coding employing regions geometrically complementary to electrical coding.
Pour cela, la clé est solidaire d'un dispositif constituant un circuit électronique à mémoire, du type circuit intégré, porteur d'un code d'ouverture, et la serrure est équipée d'un appareil électronique de lecture, comportant un circuit à mémoire programmé. La serrure n'autorise l'ouverture de la porte qu'elle équipe que si les codes respectifs de la clé et de la serrure sont les mêmes.For this, the key is integral with a device constituting an electronic memory circuit, of the integrated circuit type, carrying an opening code, and the lock is equipped with an electronic reading device, comprising a memory circuit. program. The lock authorizes the opening of the door which it equips only if the respective codes of the key and the lock are the same.
La transmission des codes entre les circuits portés par la clé et la serrure peut se faire soit par contact électrique direct, soit sans contact par une liaison magnétique, ou encore par transformateur avec primaire et secondaire, ou encore par voie radioélectrique avec émetteur et récepteur. Cet élément intermédiaire de communication est désigné habituellement sous le nom de transpondeur.The transmission of codes between the circuits carried by the key and the lock can be done either by direct electrical contact, or without contact by a magnetic link, or by transformer with primary and secondary, or by radio with transmitter and receiver. This intermediate element of communication is usually referred to as a transponder.
Parmi les applications de tels couples clé-serrure programmés, il est connu de mettre en oeuvre une pluralité de serrures et de clés, telle que celle qui existe par exemple dans un hôtel, un immeuble d'habitation, un parking. Pour cela, chaque serrure est reliée, par ligne électrique, à un ordinateur central, qui communique à chacune d'elles un code particulier, chaque serrure étant munie d'un lecteur de code.Among the applications of such programmed key-lock pairs, it is known to implement a plurality of locks and keys, such as that which exists for example in a hotel, a residential building, a parking lot. For this, each lock is connected, by electrical line, to a central computer, which communicates to each of them a particular code, each lock being provided with a code reader.
L'ouverture d'une serrure, et par conséquent la liberté d'accès au local dont elle contrôle la porte, est obtenue par présentation au niveau de la serrure, d'une clé munie d'un transpondeur, celui-ci étant porteur, dans une mémoire électronique, d'un code lisible par le lecteur de code de la serrure, chaque lecteur étant muni d'une mémoire programmée par ligne, par l'ordinateur central. Cependant, la nécessité de mettre en oeuvre des lignes électriques pour relier l'ordinateur central de programmation et les serrures satellites à programmer constitue un grave inconvénient. C'est pourquoi il a été proposé de programmer directement sur place la mémoire de chaque serrure.The opening of a lock, and consequently the freedom of access to the room which it controls the door, is obtained by presentation at the level of the lock, of a key provided with a transponder, the latter being carrier, in an electronic memory, a code readable by the code reader of the lock, each reader being provided with a memory programmed by line, by the central computer. However, the need to use power lines to connect the central programming computer and the satellite locks to be programmed is a serious drawback. This is why it has been proposed to program the memory of each lock directly on site.
Pour cela, un opérateur prend une nouvelle clé munie de son transpondeur, la mémorise dans l'ordinateur central, et ajoute éventuellement des données diverses ( nom, etc..) relatives à l'utilisateur. Il se déplace ensuite, à travers les locaux concernés, jusqu'à la serrure à programmer, muni d'un matériel électronique convenable: ordinateur portable, transpondeur, et il procède à la programmation.For this, an operator takes a new key with his transponder, stores it in the central computer, and possibly adds various data (name, etc.) relating to the user. He then moves, through the premises concerned, to the lock to be programmed, provided with suitable electronic equipment: laptop, transponder, and he proceeds to programming.
Pour obtenir l'ouverture de la porte équipée de la serrure programmée, on remet à l'usager une clé munie d'un transpondeur programmé à l'ordinateur central, et il peut ainsi pénétrer dans le local contrôlé par la serrure.To obtain the opening of the door equipped with the programmed lock, the user is given a key provided with a transponder programmed in the central computer, and he can thus enter the room controlled by the lock.
Ce système comporte toutefois lui aussi un sérieux inconvénient. Il exige en effet le passage préalable d'un opérateur devant chaque serrure à programmer, porteur d'un matériel électronique spécial, à chaque changement d'utilisateur, par exemple pour un changement de domicile, de chambre, ou de locataires autorisés ou non.However, this system also has a serious drawback. It requires the prior passage of an operator in front of each lock to be programmed, carrying special electronic equipment, at each change of user, for example for a change of domicile, room, or authorized or unauthorized tenants.
Cette obligation, dans le cas, par exemple de plusieurs centaines d'appartements dans des blocs d'immeubles H.L.M., peut se révéler pratiquement impossible à gérer.This obligation, in the case, for example, of several hundred apartments in blocks of H.L.M. buildings, may prove to be practically impossible to manage.
Le dispositif faisant l'objet de la présente invention remédie avantageusement à cet inconvénient, et, dans son principe, fait appel à la clé, associée à son transpondeur programmé pour transmettre directement à la serrure, lors de la première présentation de celle-ci, le code d'ouverture dans la mémoire de la serrure.The device which is the subject of the present invention advantageously remedies this drawback, and, in principle, uses the key, associated with its transponder programmed to transmit directly to the lock, during the first presentation of the latter, the opening code in the lock memory.
C'est ainsi le porteur de la clé qui assure lui-même la programmation de la serrure, en lieu et place d'un opérateur spécialisé et des sérieux inconvénients correspondants.It is thus the holder of the key who himself ensures the programming of the lock, in place of a specialized operator and the corresponding serious drawbacks.
Il est cependant indispensable que la transmission du code d'ouverture de la serrure ne puisse avoir lieu qu'une fois, pour des raisons évidentes de sécurité. C'est pourquoi, selon une autre caractéristique fondamentale de l'invention, il est mis en oeuvre, dans le transpondeur solidaire de la clé, une seconde mémoire programmable. Sa fonction est de donner l'ordre à la mémoire de la serrure de recopier le code d'ouverture de base de la mémoire principale présente dans le transpondeur. Cet ordre de programmation donné à la mémoire de la serrure est inscrit dans cette seconde mémoire par l'ordinateur central.However, it is essential that the transmission of the lock opening code can only take place once, for obvious security reasons. This is why, according to another fundamental characteristic of the invention, a second programmable memory is implemented in the transponder integral with the key. Its function is to order the lock memory to copy the basic opening code from the main memory present in the transponder. This programming order given to the lock memory is written to this second memory by the central computer.
Suivant la présente invention, il est mis en oeuvre un dispositif de contrôle d'accès pour porte d'un local fermé par une serrure commandée par une clé, la serrure et la clé étant munies de circuits électroniques respectifs dotés de mémoires programmables aptes à enregistrer un code d'ouverture, ces circuits respectifs étant mis en communication par un transpondeur solidaire de la clé, le circuit programmable de la clé étant programmé auprès d'un ordinateur central, caractérisé en ce que ledit circuit programmable de la clé comporte deux mémoires électroniques, une première mémoire qui assure, par le transpondeur, la transmission à la serrure du code d'ouverture, et une seconde mémoire qui assure la gestion de cette transmission, contenant les instructions donnant l'ordre d'exécution de ladite transmission, ces instructions étant ensuite effacées dans cette mémoire après exécution, par un ordre émis par la serrure.According to the present invention, an access control device is used for the door of a room closed by a lock controlled by a key, the lock and the key being provided with respective electronic circuits provided with programmable memories capable of recording. an opening code, these respective circuits being put into communication by a transponder integral with the key, the programmable circuit of the key being programmed with a central computer, characterized in that said programmable circuit of the key comprises two electronic memories , a first memory which ensures, by the transponder, the transmission to the lock of the opening code, and a second memory which ensures the management of this transmission, containing the instructions giving the order of execution of said transmission, these instructions then being erased in this memory after execution, by an order issued by the lock.
L'invention sera mieux comprise à l'aide de la description ci-après, où apparaîtront d'autres caractéristiques complémentaires.The invention will be better understood with the aid of the description below, where other additional characteristics will appear.
C'est ainsi que, comme on l'a indiqué plus haut, le transpondeur solidaire de la clé est porteur de deux mémoires, au lieu d'une seule mémoire comme dans l'art connu.Thus, as indicated above, the transponder integral with the key carries two memories, instead of a single memory as in the known art.
La première mémoire, qui par voie de simplification sera appelée mémoire A, est celle qui de façon ineffaçable, a été programmée dès la mise en service, auprès de l'ordinateur central; C'est elle qui permet d'ouvrir la porte. La seconde mémoire, caractéristique de la présente invention, et qui par voie de simplification sera appelée mémoire (B), est effaçable et enregistrable C'est elle qui contient l'instruction, destinée à la serrure, de recopier le code d'ouverture de la mémoire (A) dans ladite serrure.The first memory, which for the sake of simplification will be called memory A, is that which cannot be erased, has been programmed from the start-up, with the central computer; It is she who opens the door. The second memory, characteristic of the present invention, and which by way of simplification will be called memory (B), is erasable and recordable. It is it which contains the instruction, intended for the lock, to copy the opening code of the memory (A) in said lock.
Dans ces conditions, le dispositif selon l'invention fonctionne de la façon suivante, lors de la première présentation de la clé et de son transpondeur au niveau de la serrure. Deux cas sont possibles: S'il y a, dans la mémoire supplémentaire (B), l'inscription d'un ordre d'enregistrement du contenu de la mémoire (A) dans la serrure, suivi d'un ordre d'effacement de la mémoire (B) dans le transpondeur, la porte peut s'ouvrir, et la clé et son transpondeur ne peuvent plus servir à programmer d'autres serrures. Il s'agit là d'un avantage fondamental en cas de perte ou de vol de la clé.Under these conditions, the device according to the invention operates in the following manner, during the first presentation of the key and its transponder at the level of the lock. Two cases are possible: If there is, in the additional memory (B), the recording of an order to record the contents of the memory (A) in the lock, followed by an order to erase memory (B) in the transponder, the door can open, and the key and its transponder can no longer be used to program other locks. This is a fundamental advantage in case of loss or theft of the key.
S'il n'y a, au contraire, dans la mémoire supplémentaire (B), aucune instruction d'enregistrement de code dans la serrure, celle-ci compare le numéro de code du transpondeur - mémoire (A) -, avec le numéro de code enregistré dans sa propre mémoire, et suivant le résultat positif ou négatif de la comparaison, la porte s'ouvre ou ne s'ouvre pas. En résumé, l'invention repose sur l'effacement dans le transpondeur,du contenu de la mémoire (B) par ordre de la serrure.If, on the contrary, in the additional memory (B), there is no instruction to register the code in the lock, the latter compares the code number of the transponder - memory (A) -, with the number of code stored in its own memory, and depending on the positive or negative result of the comparison, the door opens or does not open. In summary, the invention is based on the erasure in the transponder, of the content of the memory (B) by order of the lock.
Le dispositif faisant l'objet de la présente invention a été décrit dans une application donnée à titre d'exemple, celle des immeubles à grand nombre de logements. Mais la protection de l'invention s'applique à tout domaine où un codage d'accès décentralisé est mis en oeuvre. Suivant un cas pratique donné à titre d'exemple, le dispositif de l'invention est applicable aux entrées et sorties de camion dans uns entreprise. L'entrée est libre, mais après chargement, on inscrit dans le transpondeur du chauffeur une autorisation de sortie dans sa mémoire supplémentaire, avec son uméro d'identification.The device forming the subject of the present invention has been described in an application given by way of example, that of buildings with a large number of dwellings. However, the protection of the invention applies to any field where decentralized access coding is implemented. According to a practical case given by way of example, the device of the invention is applicable to truck entrances and exits in a company. Entry is free, but after loading, an exit authorization is entered in the driver's transponder in his additional memory, with his identification number.
L'invention peut, de même, s'appliquer au contrôle de circulation dans un parking automobile payant, avec là encore, inscription dans la mémoire supplémentaire programmable, et effaçable par la serrure. The invention can likewise be applied to traffic control in a paying car park, again with registration in the programmable additional memory, which can be erased by the lock.
