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 contrôlant un accès, tel 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 vérifB 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 this 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 verifies the code supplied by the users and provides in the event of the correct code a control signal of the electrical device for actuating the device and, on the other hand, a monitoring unit arranged remotely and which makes it possible to command and / or control said access.

Un des moyens possibles de forcer l'accès pour les personnes non autorisées est d'alimenter directement de l'extérieur, à partir d'une source de tension, le dispositif électrique d'actionnement. Ceci peut être réalisé de manière relativement discrète puisqu'il suffit de pratiquer une ouverture dans l'appareil pour accéder audit dispositif d'actionnement. Il est donc désirable de prévoir un dispositif d'alarme qui permette d'avertir le poste de surveillance d'une telle tentative d'accès non autorisé. Cette alarme ne doit évidemment pas être déclenchée lors d'un accès autorisé.One of the possible means of forcing access for unauthorized persons is to supply the electrical actuating device directly from the outside, from a voltage source. This can be done relatively discreetly since it suffices to make an opening in the device to access said actuating device. It is therefore desirable to provide an alarm device which makes it possible to warn the monitoring station for such an unauthorized access attempt. This alarm should obviously not be triggered during authorized access.

La présente invention a donc pour objet un dispositif électromécanique de manoeuvre du type cité plus haut dans lequel une mise sous tension non autorisée du dispositif électrique d'actionnement déclenche 1`-émission d'une alarme à l'unité de surveillance.The present invention therefore relates to an electromechanical maneuvering device of the type mentioned above in which an unauthorized energizing of the electrical actuating device triggers the emission of an alarm to the monitoring unit.

Le dispositif électromécanique de manoeuvre selon l'invention est notamment remarquable en ce que l'unité de commande comporte un élément détecteur de tension qui est branché aux bornes du dispositif électrique d'actionnement et dont le signal de sortie est envoyé sur un circuit logique réalisant la fonction ET qui reçoit par ailleurs un signal représentatif de l'absence d'ordre d'actionnement, le signal de sortie dudit circuit logique constituant un signal d'alarme qui est transmis à l'unité de surveillance.The electromechanical operating device according to the invention is notably remarkable in that the control unit comprises a voltage detector element which is connected to the terminals of the electric actuating device and whose output signal is sent on a logic circuit carrying out the AND function which also receives a signal representative of the absence of an actuation order, the output signal of said logic circuit constituting an alarm signal which is transmitted to the monitoring unit.

Avantageusement, ledit signal d'alarme est mémorisé dans une mémoire contenue dans l'unité de commande et remise à zéro par l'unité de surveillance. De cette manière toute tentative d'alimenter le dispositif d'actionnement se traduit par une alarme qui peut être également donnée au niveau de l'accès contrôlé de manière à décourager la tentative d'actionnement non autorisé. Du fait de la mise en mémoire de cette alarme, elle n'est pas supprimée lors de l'émission ultérieure d'un ordre d'actionnement autorisé qui peut, par exemple, être fourni par une personne sortant et utilisant une commande directe non codée d'actionnement.Advantageously, said alarm signal is stored in a memory contained in the control unit and reset to zero by the monitoring unit. In this way any attempt to power the actuating device results in an alarm which can also be given at the level of the controlled access so as to discourage the unauthorized actuation attempt. Due to the storage of this alarm, it is not deleted during the subsequent transmission of an authorized actuation order which can, for example, be supplied by an outgoing person and using a direct non-coded command. actuation.

Avantageusement, l'élément détecteur de tension fournit un signal de niveau constant, indépendamment de la tension qui lui est appliquée ; grâce à cette disposition, on peut détecter des tensions nettement différentes de la tension normale d'alimentation du dispositif d'actionnement. Ceci est important car les personnes tentant de forcer la porte ne connaissent pas nécessairement la tension normale de fonctionnement du dispositif d'actionnement.Advantageously, the voltage detector element provides a constant level signal, independently of the voltage applied to it; thanks to this arrangement, it is possible to detect voltages clearly different from the normal supply voltage of the actuating device. This is important because people trying to force the door do not necessarily know the normal operating voltage of the actuator.

Ledit élément détecteur peut, par exemple, être constitué par un photocoupleur dont l'élément émetteur de lumière est branché sur les fils d'alimentation du dispositif d'actionnement, l'élément récepteur de lumière étant alimenté sous tension constante et constituant la sortie du détecteur. De cette manière on obtient un découplage parfait entre la tension appliquée sur le dispositif d'actionnement et le signal de sortie du détecteur.Said detector element may, for example, be constituted by a photocoupler, the light emitting element of which is connected to the supply wires of the actuating device, the light receiving element being supplied at constant voltage and constituting the output of the detector. In this way, perfect decoupling is obtained between the voltage applied to the actuator and the detector output signal.

Il est avantageux de coupler cette alarme avec une alarme de détection de choc ou d'arrachement de l'unité de commande et dans ce cas, le signal d'alarme précité et le signal d'alarme de chocs sont envoyés sur un circuit logique OU fournissant une alarme générale de sabotage à l'unité de-surveillance.It is advantageous to couple this alarm with a shock detection or breakout alarm of the control unit and in this case, the aforementioned alarm signal and the shock alarm signal are sent on a logic circuit OR providing a general sabotage alarm to the surveillance unit.

D'autres caractéristiques et avantages de l'invention ressortiront de la description qui suit d'un exemple d'application de l'invention ainsi que des dessins ci-annexés :

  • - la figure 1 est un schéma synoptique de l'unité de commande d'une serrure à gâche électrique conforme à la présente invention, et
  • - la figure 2 représente un exemple pratique de réalisation de l'élément détecteur de tension.
Other characteristics and advantages of the invention will emerge from the following description of an example of application of the invention as well as from the attached drawings:
  • FIG. 1 is a block diagram of the control unit of an electric strike lock according to the present invention, and
  • - Figure 2 shows a practical embodiment of the voltage detector element.

L'invention est décrite ci-après en application à la commande du déverrouillage d'une serrure à gâche électrique mais elle peut être appliquée à tous dispositifs électroniques de manoeuvre tels qu'un moteur de commande d'ouverture d'une porte, par exemple.The invention is described below in application to the control of the unlocking of an electric strike lock, but it can be applied to all electronic operating devices such as a door opening control motor, for example. .

On voit sur la figure 1 une serrure à gâche électrique qui comporte par exemple un interface d'entrée 1 qui comprend par exemple, un clavier, un lecteur de badge ou analogue permettant l'entrée du code d'ouverture de la porte ; la sortie de cet interface d'entrée est envoyée sur un comparateur 2 qui reçoit par ailleurs d'une mémoire 3 un code d'ouverture enregistré sous forme électronique. En cas de coincidence des deux codes, lè comparateur fournit un signal d'ouverture qui est mémorisé dans la mémoire 4 et envoyé à la gâche électrique 5.We see in Figure 1 an electric strike lock which includes for example an input interface 1 which includes, for example, a keyboard, a badge reader or the like allowing the entry of the door opening code; the output of this input interface is sent to a comparator 2 which also receives an opening code recorded in electronic form from a memory 3. If the two codes coincide, the comparator provides an opening signal which is memorized in memory 4 and sent to the electric strike 5.

Conformément à l'invention, on prévoit un détecteur de tension 6 qui est branché en parallèle sur les fils d'alimentation du dispositif électrique d'ouverture de la gâche 5 ; le signal de sortie de ce détecteur 6 est combiné à un signal significatif de l'absence d'un ordre d'ouverture fourni par la mémoire 4 et le circuit inverseur 10 dans un circuit logique ET 7 dont la sortie fournit un signal d'alarme d'alimentation électrique directe de gâche électrique 5.In accordance with the invention, a voltage detector 6 is provided which is connected in parallel to the supply wires of the electric device for opening the keeper 5; the output signal of this detector 6 is combined with a significant signal of the absence of an opening order provided by the memory 4 and the inverter circuit 10 in an AND logic circuit 7 the output of which provides an alarm signal direct electric supply of electric strike 5.

Selon une autre caractéristique de l'invention, l'unité de commande comporte également un détecteur 8 détectant des chocs ou des arrachements subis par l'unité de commande et qui délivre donc un signal d'alarme de chocs ou d'arrachements subis par l'unité centrale. Le signal d'alarme d'alimentation fourni par la porte logique ET 7 et le signal d'alarme de chocs ou d'arrachements fourni par le détecteur 8 sont combinés dans un circuit logique OU 9 qui fournit à sa sortie un signal d'alarme général de tentative de sabotage.According to another characteristic of the invention, the control unit also comprises a detector 8 detecting shocks or tears suffered by the control unit and which therefore delivers an alarm signal of shocks or tears suffered by the 'central unit. The power supply alarm signal supplied by the AND logic gate 7 and the shock or breakout alarm signal supplied by the detector 8 are combined in an OR logic circuit 9 which provides an alarm signal at its output general sabotage attempt.

Avantageusement, le signal d'alarme d'alimentation ou de chocs ou d'arrachements est mémorisé dans une mémoire 11 puis envoyé à l'unité de surveillance (non représentée). Cette dernière comporte une commande de remise à zéro de la mémoire 11, par exemple par l'intermédiaire d'une ligne 12.Advantageously, the supply or shock or tear-off alarm signal is stored in a memory 11 and then sent to the monitoring unit (not shown). The latter includes a command to reset memory 11, for example via a line 12.

La figure 2 représente un mode de réalisation avantageux de l'élément détecteur de tension 6. En effet, les auteurs de la tentative d'ouverture non autorisée ne connaissent pas nécessairement la tension normale d'alimentation de la gâche électrique et ils peuvent appliquer des tensions très nettement différentes de cette tension normale d'alimentation. Il faut donc pouvoir s'affranchir des variations de tension aux bornes. du détecteur, c'est-à-dire qu'il faut choisir un détecteur dont le signal de sortie est indépendant de la tension détectée. Ceci peut par exemple être réalisé en utilisant un photocoupleur 13, c'est-à-dire un composant comportant d'une part un émetteur de lumière 14 et un récepteur de lumière 15 couplés optiquement. La partie émetteur de lumière du photocoupleur 13 est branchée aux bornes des conducteurs d'alimentation de la gâche électrique 5 par l'intermédiaire d'une résistance 16 et d'une diode 17 de protection. La partie récepteur de lumière est quant à-el-le alimentée par une tension constante par l'intermédiaire d'une résistance 18, son autre borne étant reliée à la masse. De cette manière on obtient en 19 sur la borne du récepteur de lumière reliée à la source d'alimentation positive un signal logique qui est au niveau haut en l'absence de tension détectée par le récepteur de lumière 15 et au niveau bas lorsque cet élément 14 est alimenté. On obtient donc en 19 un signal qui est représentatif de la tension aux bornes de la gâche électrique 5 mais inversé du fait qu'une absence de tension se traduit par un niveau haut.FIG. 2 represents an advantageous embodiment of the voltage detector element 6. In fact, the authors of the unauthorized opening attempt do not necessarily know the normal supply voltage of the electric strike and they can apply voltages very clearly different from this normal supply voltage. It is therefore necessary to be able to overcome variations in voltage across the terminals. of the detector, that is to say choose a detector whose output signal is independent of the detected voltage. This can for example be achieved using a photocoupler 13, that is to say a component comprising on the one hand a light emitter 14 and a light receiver 15 optically coupled. The light emitting part of the photocoupler 13 is connected to the terminals of the power supply conductors of the electric strike 5 by means of a resistor 16 and a protective diode 17. The light receiving part is for its part supplied by a constant voltage via a resistor 18, its other terminal being connected to ground. In this way there is obtained at 19 on the terminal of the light receiver connected to the positive power source a logic signal which is at the high level in the absence of voltage detected by the light receiver 15 and at the low level when this element 14 is powered. There is therefore obtained in 19 a signal which is representative of the voltage across the terminals of the electric strike 5 but reversed because an absence of voltage results in a high level.

Dans cet exemple de réalisation, le circuit ET 7 est constitué en fait par un circuit NON OU 21 qui reçoit des signaux complémentaires de ceux fournis au circuit ET 7, c'est-à-dire que le deuxième port du circuit NON OU 21 reçoit un signal représentatif de la présence d'un ordre mais inversé c'est-à-dire que ce signal est au niveau haut en l'absence d'un signal d'ouverture normale de la porte. On voit que l'invention permet d'obtenir une alarme instantanée dès la première tentative de branchement d'une tension d'alimentation sur la gâche électrique et cela indépendamment de la valeur de cette tension.In this embodiment, the AND circuit 7 is in fact constituted by a NOR circuit 21 which receives signals complementary to those supplied to the AND circuit 7, that is to say that the second port of the NOR circuit 21 receives a signal representative of the presence of an order but inverted, that is to say that this signal is at the high level in the absence of a signal for normal opening of the door. It can be seen that the invention makes it possible to obtain an instant alarm as soon as the first attempt is made to connect a supply voltage to the electric strike, regardless of the value of this voltage.

- L'alimentation électrique du dispositif d'actionnement est généralement fournie par le réseau de distribution avec une batterie tampon ; dans le cas de la commande d'une porte d'habitation par exemple, l'utilisation d'une batterie tampon permet d'obtenir l'ouverture de la porte en cas de coupure de l'alimentation du réseau. Toutefois, dans le cas d'une absence longue du propriétaire, il peut se produire une coupure prolongée du réseau qui soit supérieure à l'autonomie de la batterie montée en tampon et dans ce cas il ne serait pas possible d'obtenir l'ouverture de la porte après cette longue coupure du réseau.- The power supply to the actuating device is generally supplied by the distribution network with a buffer battery; in the case of controlling a residential door for example, the use of a buffer battery makes it possible to obtain the opening of the door in the event of a cut in the supply to the network. However, in the case of a long absence from the owner, there may be a prolonged outage of the network which is greater than the autonomy of the buffered battery and in this case it would not be possible to obtain the opening from the door after this long power outage.

Conformément à l'invention, on prévoit au niveau de l'unité de commande un dispositif de connexion d'une batterie extérieure, ce dispositif de connexion n'étant validé, c'est-à-dire mis en liaison avec le dispositif d'actionnement que si le réseau est coupé et si la batterie tampon est hors service. Cette disposition permet à l'usager de pénétrer dans son habitation même après une longue coupure du réseau ayant entraîné la mise hors service de la batterie tampon. Avantageusement, cette batterie tampon est automatiquement mise hors service avant qu'elle n'atteigne un état de décharge qui la rende inutilisable.According to the invention, there is provided at the control unit a device for connecting an external battery, this connection device not being validated, that is to say put in connection with the device actuation only if the network is cut and if the buffer battery is out of service. This arrangement allows the user to enter his home even after a long interruption of the network which led to the buffer battery being out of service. Advantageously, this buffer battery is automatically put out of service before it reaches a discharge state which renders it unusable.

La description ci-dessus n'a été fournie qu'à titre d'exemples illustratifs et nullement limitatifs et il est évident que l'on peut y apporter des modifications ou variantes sans pour autant sortir du cadre de la présente invention. Comme on l'a vu en particulier, on peut remplacer certains composants par des composants remplissant la même fonction comme c'est le cas par exemple pour le circuit logique NON OU 21 qui remplace le circuit logique ET de la figure 1.The above description has been provided by way of illustrative and in no way limitative examples and it is obvious that modifications or variants can be made without departing from the scope. of the present invention. As we have seen in particular, it is possible to replace certain components by components fulfilling the same function as is the case for example for the logic circuit NOR OR 21 which replaces the logic circuit AND of FIG. 1.
