Description

L'invention concerne les dispositifs électromécaniques de manoeuvre qui sont commandés par un code de manière à ne permettre l'accès à un appareil donné qu'à des personnes autorisées; ces dispositifs comportent de manière générale une unité de commande située à proximité de l'appareil à contrôler et qui comprend un interface d'entrée de code relié à un comparateur qui reçoit par ailleurs le contenu d'une mémoire contenant un code d'actionnement; ce comparateur commande un dispositif électrique d'actionnement de l'appareil contrôlé. Une unité de surveillance située à distance et reliée à l'unité de commande par un dispositif de transmission tel qu'un câble permet de surveiller l'accés à l'appareil contrôlé. Le code d'actionnement peut être introduit au moyen d'un clavier, d'un badge portant le code, d'une carte magnétique ou encore d'une cellule photoélectrique émettant un code sous forme lumineuse, par exemple une cellule à infra-rouge.The invention relates to electromechanical operating devices which are controlled by a code so as to allow access to a given device only to authorized persons; these devices generally include a control unit located near the device to be controlled and which comprises a code entry interface connected to a comparator which also receives the content of a memory containing an actuation code; this comparator controls an electrical device for actuating the controlled device. A monitoring unit located remotely and connected to the control unit by a transmission device such as a cable makes it possible to monitor access to the controlled device. The actuation code can be entered by means of a keyboard, a badge bearing the code, a magnetic card or even a photoelectric cell emitting a code in light form, for example an infrared cell. .

Le brevet FR-A-2 399 520 décrit un système sans clef comprenant une station de commande munit d'un générateur de signaux électriques sans clef, un moyen logique pour traiter des signaux électriques appropriés de la station de commande et un moyen répondant à la sortie logique pour commander un mécanisme tel que, une serrure. D'une façon typique, un signal électrique numérique est produit à une station de commande manuelle par la manipulation séquentielle d'une pluralité de points de touches sensibilisés. Le signal est dirigé vers un moyen logique qui compare le signal du générateur avec un code de référence et sous des conditions acceptables peut être programmé pour accepter un code convenable subséquent et fournit une sortie qui est amplifiée et dirigée vers un moteur électrique pour changer la position physique d'un élément de retenue dans le système d'entrée.The patent FR-A-2 399 520 describes a keyless system comprising a control station provided with a keyless electrical signal generator, a logical means for processing appropriate electrical signals from the control station and a means responding to the logic output to control a mechanism such as a lock. Typically, a digital electrical signal is produced at a manual control station by the sequential manipulation of a plurality of sensitized key points. The signal is directed to logic means which compares the generator signal with a reference code and under acceptable conditions can be programmed to accept a subsequent suitable code and provides an output which is amplified and directed to an electric motor to change the position physics of a restraint in the entry system.

Les personnes non autorisées qui veulent forcer de manière mécanique l'accès de l'appareil contrôlé par le dispositif décrit ci-dessus crée des chocs sur le dispositif et son unité de commande, par exemple en tentant de briser une vitre ou un panneau dans le cas du contrôle d'une porte; ces personnes peuvent également tenter d'ouvrir ou d'arracher l'unité de commande afin d'accéder au dispositif de codage ou au conducteur du dispositif électrique d'actionnement. Même s'ils sont bruyants, de tels agissements ne sont pas percus par l'unité de surveillance qui est éloignée de l'accès contrôlé. Or, une effraction de l'accès contrôlé nécessite un temps relativement long et il est désirable que l'unité de surveillance soit prévenue dès le début d'une telle tentative afin de pouvoir intervenir avant que l'accès n'aie été forcé.Unauthorized persons who want to force mechanical access to the device controlled by the device described above creates shocks to the device and its control unit, for example by trying to break a window or a panel in the door control case; these people can also try to open or tear off the control unit in order to access the coding device or the conductor of the electrical actuation device. Even if they are noisy, such actions are not perceived by the surveillance unit which is far from controlled access. However, a breach of the controlled access requires a relatively long time and it is desirable that the surveillance unit be notified at the start of such an attempt in order to be able to intervene before the access has been forced.

On connaît déjà des systèmes de protection et d'alarme. Le brevet EP-A-0 031 405 décrit un système de protection comportant des éléments de détection, permettant de déclencher une émission d'alarme transmisse à l'unité de surveillance. Le brevet FR-A-2 371 738 décrit un système antivol dans lequel une alarme est déclenchée lors de l'ouverture d'un circuit électrique. Cependant ces dispositifs connus ne permettent pas de résoudre le problème de la détection du forçage mécanique de l'appareil surveillé.Protection and alarm systems are already known. Patent EP-A-0 031 405 describes a protection system comprising detection elements, making it possible to trigger an alarm transmission transmitted to the monitoring unit. Patent FR-A-2,371,738 describes an anti-theft system in which an alarm is triggered when an electrical circuit is opened. However, these known devices do not make it possible to solve the problem of detecting the mechanical forcing of the monitored device.

La présente invention à donc pour objet un dispositif électromécanique de manoeuvre du type cité plus haut qui comporte un dispositif permettant d'avertir l'unité de surveillance de toute tentative de forçage de l'accès contrôlé.The present invention therefore relates to an electromechanical maneuvering device of the type mentioned above which comprises a device making it possible to warn the monitoring unit of any attempt to force the controlled access.

Le dispositif électromécanique de manoeuvre selon l'invention est notamment remarquable en ce que l'unité de commande comporte un élément de détection de chocs et un élément de détection d'arrachements qui sont branchés de manière à réaliser un circuit logique OU déclenchant l'émission d'une alarme qui est transmise à l'unité de surveillance. De cette manière, dès le début de la tentative d'effraction, l'alarme est donnée à l'unité de surveillance qui peut alors intervenir.The electromechanical operating device according to the invention is notably remarkable in that the control unit comprises a shock detection element and a breakout detection element which are connected so as to produce a logic circuit OR triggering the emission an alarm which is transmitted to the monitoring unit. In this way, from the start of the break-in attempt, the alarm is given to the monitoring unit which can then intervene.

Cette alarme peut également être rendue perceptible au niveau de l'ouverture contrôlée, par exemple sous forme sonore et/ou optique, et manière à décourager les personnes tentant l'effraction.This alarm can also be made perceptible at the controlled opening, for example in audible and / or optical form, and so as to discourage people attempting to break in.

Avantageusement, l'unité de commande comporte un dispositif de mémorisation de ladite alarme, ledit dispositif de mémorisation étant remis à zéro à distance par l'unité de surveillance. Ceci permet en particulier d'éliminer une alarme due à un choc fortuit isolé.Advantageously, the control unit comprises a device for storing said alarm, said storing device being remotely reset by the monitoring unit. This allows in particular to eliminate an alarm due to an isolated accidental shock.

La manoeuvre de l'appareil contrôlé, risque de créer des chocs qui seront perçus par l'élément détecteur de chocs; c'est le cas en particulier dans le cas où l'appareil contrôlé est une porte dont la fermeture peut créer des chocs au niveau de l'unité de commande, le dispositif électromécanique de manoeuvre commandant soit un verrou électrique soit directement un moteur d'ouverture de la porte. C'est pourquoi dans ce cas, l'unité de commande comporte en outre un élément détecteur de l'état de fermeture de la porte commandé par la serrure, cet élément détecteur inhibant le signal d'alarme fourni par l'élément de détection de chocs ou l'élément de détection d'arrachements pendant une période prédéterminée succédant à la fermeture de la porte.Maneuvering the controlled device may create shocks which will be perceived by the shock detector element; this is the case in particular in the case where the controlled device is a door, the closing of which can create shocks at the level of the control unit, the electromechanical operating device controlling either an electric lock or directly a motor of door opening. This is why in this case, the control unit further comprises an element for detecting the state of closing of the door controlled by the lock, this sensor element inhibiting the alarm signal supplied by the element for detecting shocks or the tear-off detection element for a predetermined period following the closing of the door.

Avantageusement, cet élément détecteur de fermeture de porte commande le verrouillage de la serrure. Ceci peut par exemple être réalisé par le fait que le dispositif électrique d'ouverture comporte un dispositif de mémoire mémorisant l'ordre d'ouverture, ledit dispositif de mémoire étant remis à zéro par ledit élément détecteur de la fermeture de la porte.Advantageously, this door closing detector element controls the locking of the lock. This can for example be achieved by the fact that the electrical opening device comprises a memory device memorizing the opening order, said memory device being reset to zero by said element for detecting the closing of the door.

D'autres caractéristiques et avantages de l'invention ressortiront de la description qui suit ainsi que du dessin "Dispositif électromécanique de manoeuvre commandé par code et protégé contre les chocs et les arrachements".Other characteristics and advantages of the invention will emerge from the description which follows as well as from the drawing "Electromechanical operating device controlled by code and protected against shocks and tears".

Le dispositif électromécanique de manoeuvre selon l'invention est ci-annexé représentant sous forme d'un schéma synoptique une serrure à gâche électrique conforme à la présente invention.The electromechanical operating device according to the invention is attached hereto representing in the form of a block diagram an electric strike lock in accordance with the present invention.

L'invention est décrite ci-après en application à une serrure à gâche électrique et il est évident qu'elle peut s'appliquer à tous dispositifs électromécaniques de manoeuvre commandés par un code et controlant l'accès ou l'actionnement d'un appareil quelconque.The invention is described below in application to an electric strike lock and it is obvious that it can be applied to all electromechanical operating devices controlled by a code and controlling access or actuation of a device any.

La serrure à gâche électrique représentée sur la figure comporte une unité de commande 1 disposée à proximité de la serrure à commander, par exemple sur la porté portant la serrure et une unité de surveillance 20 disposée à distance et reliée à l'unité de commande 1 par un dispositif de transmission constitué par exemple par un câble.The electric strike lock shown in the figure comprises a control unit 1 arranged near the lock to be controlled, for example on the door carrying the lock and a monitoring unit 20 arranged remotely and connected to the control unit 1 by a transmission device constituted for example by a cable.

De manière classique, l'unité de commande 1 comprend un interface d'entrée 2 qui peut comporter un clavier ou être commandé par un dispositif de codage tel qu'une carte magnétique, un badge ou une cellule optique à code infra-rouge. Le code fourni par cet interface 2 est envoyé sur un comparateur 3 qui reçoit également un code d'ouverture enregistré sous forme électronique dans une mémoire 4. La sortie du comparateur 3 commande un dispositif électrique d'ouverture constitué par la gâche électrique 5. Avantageusement l'unité de commande 1 comporte un dispositif de mémorisation 6 qui mémorise l'ordre d'ouverture fourni par le comparateur 3.Conventionally, the control unit 1 comprises an input interface 2 which may include a keyboard or be controlled by a coding device such as a magnetic card, a badge or an optical cell with infrared code. The code provided by this interface 2 is sent to a comparator 3 which also receives an opening code recorded in electronic form in a memory 4. The output of the comparator 3 controls an electric opening device constituted by the electric strike 5. Advantageously the control unit 1 comprises a storage device 6 which stores the opening order provided by the comparator 3.

L'unité de commande comporte également un circuit de commande et de contrôle 7 qui est relié à l'unité de surveillance 20 de manière à permettre la commande et la surveillance à distance de la porte supportant la serrure électrique.The control unit also includes a command and control circuit 7 which is connected to the monitoring unit 20 so as to allow remote control and monitoring of the door supporting the electric lock.

Conformément à l'invention, on prévoit un élément détecteur de chocs 8 et un élément détecteur d'arrachements 9 qui sont branchés de manière à réaliser un circuit logique OU qui déclenche l'émission d'un signal d'alarme. Dans l'exemple représenté, le détecteur de chocs est constitué par un interrupteur 8 comportant un contact mobile sensible au choc et le détecteur d'arrachement est constitué par un interrupteur 9 comportant au moins un contact fixe solidaire du socle ou du support de l'unité de commande et un contact mobile solidaire d'une partie amovible de l'unité de commande ou de l'unité de commande elle-même. Ces deux interrupteurs sont branchés en série avec une résistance 11, l'ensemble étant en parallèle sur les bornes d'un condensateur 12 qui est relié d'une part à une source de tension positive par l'intermédiaire d'une autre résistance 13 et d'autre part, à la masse. De cette manière, on obtient un circuit réalisant la fonction logique OU qui fournit à la sortie d'une porte inverseuse 14 un signal de niveau 0 lorsqu'au moins un des interrupteurs 8 ou 9 est ouvert. Le signal d'alarme obtenu est mémorisé dans un dispositif à mémoire 15 puis envoyé à l'unité de surveillance 20 par exemple par l'intermédiaire d'une ligne 16.According to the invention, there is provided a shock detector element 8 and a breakout detector element 9 which are connected so as to produce an OR logic circuit which triggers the emission of an alarm signal. In the example shown, the shock detector is constituted by a switch 8 comprising a movable contact sensitive to shock and the tear-off detector is constituted by a switch 9 comprising at least one fixed contact secured to the base or the support of the control unit and a movable contact secured to a removable part of the control unit or of the control unit itself. These two switches are connected in series with a resistor 11, the assembly being in parallel on the terminals of a capacitor 12 which is connected on the one hand to a positive voltage source via another resistor 13 and on the other hand, to ground. In this way, a circuit is obtained which performs the OR logic function which supplies a level 0 signal at the output of a reversing gate 14 when at least one of the switches 8 or 9 is open. The alarm signal obtained is stored in a memory device 15 and then sent to the monitoring unit 20 for example via a line 16.

L'unité de commande 1 comporte également un élément détecteur de fermeture de la porte constitué par exemple par un contact 17 qui est fermé lorsque la porte est fermée. Ce contact de fermeture de porte 17 est disposé dans un circuit analogue à celui des éléments détecteur de chocs et d'arrachement et comportant une résistance série 18, un condensateur 19 et une résistance 21 reliée à une source d'alimentation. La sortie du circuit ainsi constitué qui passe à un niveau bas lorsque le contact 17 se ferme est reliée par exemple à une bascule 22 du type commandé par un front descendant. Le signal de fermeture de porte obtenu commande un circuit de temporisation 23 dont le signal de sortie commande un circuit de validation 24 constitué par exemple par une porte logique de manière à bloquer le passage du signal d'alarme lorsque le signal temporisé de fermeture de porte est présent. Par ailleurs, le circuit de temporisation 23 commande la remise à zéro du dispositif de méri- sation 6 lors de la disparition du signal temporisé de fermeture de porte.The control unit 1 also includes a door closing detector element constituted for example by a contact 17 which is closed when the door is closed. This door closing contact 17 is arranged in a circuit similar to that of the shock and breakout detector elements and comprising a series resistor 18, a capacitor 19 and a resistor 21 connected to a power source. The output of the circuit thus formed which goes to a low level when the contact 17 closes is connected for example to a flip-flop 22 of the type controlled by a falling edge. The door closing signal obtained controls a time delay circuit 23, the output signal of which activates a validation circuit 24 constituted for example by a logic door so as to block the passage of the alarm signal when the time delayed door closing signal is present. Furthermore, the delay circuit 23 controls the resetting of the merization device 6 when the delayed door closing signal disappears.

La commande de refermeture et/ou de rever- rouillage n'est données qu'à la fin de la temporisation du circuit 23 et que si la porte est restée fermée durant cette temporisation. Ceci permet d'éviter toutes manoeuvres ou tentatives de fraude par une refermeture suivie d'une réouverture très rapide avant que les pênes n'aient pu fonctionner.The reclosing and / or relocking command is only given at the end of the circuit 23 time delay and only if the door has remained closed during this time delay. This makes it possible to avoid any maneuvers or attempts at fraud by a reclosing followed by a very rapid reopening before the bolts have been able to function.

Par ailleurs le circuit 15 de mémorisation du signal d'alarme de chocs ou d'arrachements est remis à zéro par l'unité de surveillance 20 par exemple par l'intermédiaire d'une ligne 25.Furthermore, the circuit 15 for storing the shock or breakout alarm signal is reset to zero by the monitoring unit 20, for example via a line 25.

Le fonctionnement du circuit qui vient d'être décrit est le suivant: en l'absence du signal de fermeture de porte fourni par le circuit de temporisation 23, toute ouverture d'un des contacts 8 ou 9 provoque un signal d'alarme de choc ou d'arrachement qui est transmis par le circuit de validation 24 à la mémoire 15 puis à l'unité de surveillance. Le personnel présent à cette unité de surveillance peut annuler cette alarme en agissant sur la remise à zéro de la mémoire 15 et s'il ne se produit pas d'autres chocs ou arrachements, l'alarme disparaît. Cette alarme peut être produite visuellement ou de manière sonore au niveau de la porte contrôlée par la serrure de manière à dissuader les personnes tentant de forcer la porte.The operation of the circuit which has just been described is as follows: in the absence of the door closing signal supplied by the timing circuit 23, any opening of one of the contacts 8 or 9 causes a shock alarm signal or tear which is transmitted by the validation circuit 24 to the memory 15 then to the monitoring unit. The personnel present at this monitoring unit can cancel this alarm by acting on the reset of the memory 15 and if no other shocks or tears occur, the alarm disappears. This alarm can be produced visually or audibly at the door controlled by the lock so as to dissuade people trying to force the door.

Lorsque la porte a été ouverte, par une personne autorisée par exemple, le contact 17 est ouvert et lorsque la porte se referme, son contact se referme également ce qui crée un signal de fermeture de porte par l'intermédiaire de la bascule 22. Ce signal temporisé dans le circuit de temporisation 23 bloque le passage du signal d'alarme de chocs ou d'arrachements à travers le circuit de validation 24 et il n'y a donc pas d'émission de signal d'alarme de chocs ou d'arrachements. La temporisation du circuit 23 est réglée à une valeur faible, par exemple une seconde.When the door has been opened, for example by an authorized person, the contact 17 is open and when the door closes, its contact also closes, which creates a door closing signal by means of rocker 22. This delayed signal in the delay circuit 23 blocks the passage of the shock or breakout alarm signal through the validation circuit 24 and there is therefore no emission of a shock alarm signal or tears. The timing of circuit 23 is set to a low value, for example one second.

La disparition du signal temporisé de fermeture de la porte entraîne la remise à zéro du circuit de mémorisation 6, ce qui supprime l'ordre d'ouverture de la porte envoyé à la gâche électrique 5; de plus, la disparition du signal temporisé de fermeture de porte entraîne l'émission d'un ordre de fermeture du pêne de verrouillage du verrou 5.The disappearance of the timed door closing signal causes the storage circuit 6 to be reset to zero, which eliminates the order to open the door sent to the electric strike 5; moreover, the disappearance of the timed door closing signal results in the emission of a gold dre of closing the bolt for locking the lock 5.

Avantageusement, le détecteur de chocs comporte un dispositif distinguant les chocs de faible amplitude des chocs de grande amplitude; ceci peut par exemple être réalisé par la mesure du temps d'ouverture de l'interrupteur 8.Advantageously, the shock detector comprises a device distinguishing the shocks of small amplitude from the shocks of large amplitude; this can for example be achieved by measuring the opening time of the switch 8.

Dans le cas d'un pavillon où la porte de la rue est commandée par un code, le dispositif de surveillance étant dans le pavillon, ce dispositif est particulièrement intéressant. Avantageusement, on peut utiliser les microphones de l'interphone pour réaliser l'alarme sonore locale.In the case of a pavilion where the door to the street is controlled by a code, the surveillance device being in the pavilion, this device is particularly advantageous. Advantageously, the intercom microphones can be used to carry out the local audible alarm.

On voit que l'invention permet l'émission d'un signal d'alarme de chocs ou d'arrachements pour tous chocs ou arrachements de l'unité de commande résultant d'une tentative d'effraction, cette alarme étant inhibée lors de la fermeture de la porte.It can be seen that the invention allows the emission of a shock or breakout alarm signal for any shock or breakout of the control unit resulting from an attempted break-in, this alarm being inhibited during the door closing.

La description ci-dessus n'a été fournie qu'à titre d'exemple illustratif et nullement limitatif et il est entendu que l'on peut y apporter des modifications ou variantes sans pour autant sortir du cadre de la présente invention. En particulier on peut remplacer certains composants par des composants différents remplissant des fonctions semblables.The above description has been provided by way of illustrative and in no way limitative example and it is understood that modifications or variants can be made without departing from the scope of the present invention. In particular, it is possible to replace certain components with different components fulfilling similar functions.
