Description

Domaine de l'inventionField of the invention

La présente invention concerne un dispositif d'alarme avec détection d'ouverture d'ouvrant tel que porte ou fenêtre, pourvu de moyens permettant une discrimination entre un occupant légitime et un intrus en particulier lorsque l'ouvrant est manœuvré.The present invention relates to an alarm device with detection of the opening of an opening such as a door or window, provided with means allowing discrimination between a legitimate occupant and an intruder, in particular when the opening is operated.

Arrière plan technologiqueTechnological background

Dans les systèmes d'alarme, de nombreux détecteurs d'ouverture existent. Ils sont en particulier utilisés pour la protection des habitats, des locaux professionnels ou des bureaux. Ils sont en général incorporés dans un système de sécurité et reliés par liaison filaire ou par radio à une centrale d'alarme.In alarm systems, many opening detectors exist. They are used in particular for the protection of homes, professional premises or offices. They are generally incorporated into a security system and connected by wire or radio to an alarm centre.

Pour la protection de ces locaux, les systèmes d'alarme disposent la plupart du temps de deux types de capteurs, des détecteurs d'ouverture d'ouvrants tels que portes et fenêtres et des détecteurs de mouvement à ultrasons ou à infrarouges.For the protection of these premises, alarm systems usually have two types of sensors, opening detectors such as doors and windows and ultrasonic or infrared motion detectors.

Pour une habitation par exemple, lorsque l'habitation est vide les deux types de capteurs sont en service. Par contre, lorsque l'habitation est occupée, la nuit par exemple, seuls sont activés les détecteurs d'ouverture de portes ou de fenêtres. Cette protection est appelée protection périphérique.For a dwelling, for example, when the dwelling is empty, the two types of sensors are in service. On the other hand, when the dwelling is occupied, at night for example, only the door or window opening detectors are activated. This protection is called peripheral protection.

Dans un tel cas il faut évidemment désactiver l'alarme avant d'ouvrir les portes et/ou fenêtres.In such a case it is obviously necessary to deactivate the alarm before opening the doors and/or windows.

Un tel système est donc contraignant et l'ouverture d'un ouvrant tel que porte ou fenêtre depuis l'intérieur du local va déclencher des fausses alarmes.Such a system is therefore restrictive and the opening of an opening such as a door or window from inside the room will trigger false alarms.

Or il peut être nécessaire de pouvoir ouvrir certaines portes et fenêtres depuis l'intérieur des locaux protégés sans déclencher l'alarme.However, it may be necessary to be able to open certain doors and windows from inside the protected premises without triggering the alarm.

De même pour des locaux professionnels, il peut être nécessaire de vérifier depuis quel côté une porte ou une fenêtre est ouverte, par exemple pour un local dont l'accès est restreint mais dont la sortie est libre.Similarly for business premises, it may be necessary to check from which side a door or window is open, for example for a room whose access is restricted but whose exit is free.

Dans ce domaine sont connus les documents US 12 127317 A1 , US 2008/0157964 A1 , US 2016/0247370 A1 et WO 2016/109335 A1 qui proposent de valider ou non une alarme d'ouvrant en fonction de la présence ou non d'un occupant dans le local à protéger.In this field are known the documents US 12 127317 A1 , US 2008/0157964 A1 , US 2016/0247370 A1 and WO 2016/109335 A1 which propose to validate or not an opening alarm according to the presence or not of an occupant in the room to be protected.

Brève description de l'inventionBrief description of the invention

La présente invention propose dans ce contexte un dispositif de détection d'ouverture perfectionné adapté à discriminer des tentatives d'ouverture d'un ouvrant en fonction du côté où se situe la tentative d'ouverture pour déclencher une alarme dans le cas où un intrus est détecté et ne pas déclencher d'alarme dans le cas où un occupant légitime est détecté, ce dispositif restant utilisable même lorsqu'un ouvrant est partiellement ouvert.The present invention proposes in this context an improved opening detection device suitable for discriminating attempts to open an opening according to the side on which the opening attempt is located in order to trigger an alarm in the event that an intruder is detected and not triggering an alarm in the event that a legitimate occupant is detected, this device remaining usable even when an opening is partially open.

    • presence detection, in the distrust perimeter, by the second presence detection means without or before operator presence detection, in said confidence perimeter, by the first presence detection means,
    and,
  2. b - sequences of events not triggering an alarm comprising

    • a detection of an operator in the perimeter of confidence framing a detection of presence in the perimeter of distrust;

Description détaillée de modes de réalisation de l'invention:Detailed description of embodiments of the invention:

La présente invention a par exemple pour but de permettre d'activer un système d'alarme en mode périphérique tout en continuant à vivre normalement dans son habitat sans avoir à craindre de provoquer de fausses alarmes sur des actions de la vie courante comme l'ouverture d'une fenêtre pour fermer les volets ou aérer une pièce, l'ouverture de la porte pour sortir la poubelle ou laisser sortir le chien, ou toute autre action sur les ouvrants depuis l'intérieur du périmètre sécurisé alors qu'une tentative d'ouverture des ouvrants par l'extérieur déclenchera une alarme.The aim of the present invention is, for example, to make it possible to activate an alarm system in peripheral mode while continuing to live normally in one's habitat without having to fear causing false alarms on actions of everyday life such as opening a window to close the shutters or ventilate a room, opening the door to take out the trash or let the dog out, or any other action on the openings from inside the secure perimeter while an attempt to open the openings from the outside will trigger an alarm.

Le dispositif schématisé en figure 1 est un exemple de réalisation d'un dispositif de protection d'un ouvrant à simple détection de présence intérieure qui comporte un module 10 réalisé sous forme d'un boîtier 15 destiné à s'appliquer par collage, vissage ou autre méthode sur un premier côté d'un ouvrant comme représenté aux figures 2 et 3.The device schematized in figure 1 is an exemplary embodiment of a device for protecting an opening with simple interior presence detection which comprises a module 10 produced in the form of a box 15 intended to be applied by gluing, screwing or another method on a first side of an opening as shown in figure 2 and 3 .

Ce module peut être muni d'un dispositif anti-vandalisme dit « anti-tamper » qui détecte automatiquement le changement de sa position initiale comme par exemple dans le cas d'un acte de vandalisme.This module can be provided with an anti-vandalism device called “anti-tamper” which automatically detects the change of its initial position as for example in the case of an act of vandalism.

Le module de la figure 1 comporte des moyens 11 de détection de mouvement dudit ouvrant.The module of the figure 1 comprises means 11 for detecting movement of said opening.

Ces moyens de détection peuvent être de plusieurs types comme:

  • des moyens magnétiques, dans ce cas un module complémentaire tel qu'un aimant ou une masse métallique est disposé en regard du module 10 sur une partie de dormant de l'ouverture à protéger;
  • un magnétomètre qui va directement détecter la variation de direction du champ magnétique terrestre lors de la mise en mouvement de l'ouvrant;
  • des moyens de type accéléromètre qui vont détecter une mise en mouvement de l'ouvrant, ou tout autre moyen permettant de détecter une mise en mouvement de l'ouvrant.
These detection means can be of several types such as:
  • magnetic means, in this case an additional module such as a magnet or a metal mass is placed opposite the module 10 on a part of the frame of the opening to be protected;
  • a magnetometer which will directly detect the variation in direction of the earth's magnetic field when the sash is set in motion;
  • means of the accelerometer type which will detect movement of the opening, or any other means making it possible to detect movement of the opening.

Le module comporte en outre des moyens 12 de détection de présence dans un périmètre restreint et situé d'un seul côté de l'ouvrant.The module further comprises means 12 for detecting presence within a restricted perimeter and located on one side of the opening only.

Le périmètre de détection est circonscrit à une distance de manœuvre du mécanisme d'ouverture 23, 24 de l'ouvrant par un opérateur.The detection perimeter is limited to a maneuvering distance from the opening mechanism 23, 24 of the opening by an operator.

Les moyens de détection de présence peuvent être aussi de plusieurs types comme:

  • des moyens infrarouges directionnels détectant la chaleur d'un opérateur proche du dispositif fixé sur l'ouvrant;
  • des moyens radar détectant la réflexion de l'onde par l'opérateur proche du dispositif fixé sur l'ouvrant.
The presence detection means can also be of several types such as:
  • directional infrared means detecting the heat of an operator close to the device fixed on the opening;
  • radar means detecting the reflection of the wave by the operator close to the device fixed on the opening.

Les moyens de détection de présence sont préférablement directionnels ou avec un cône de détection étroit et sont par exemple adaptés à détecter une présence sur une distance réduite, par exemple jusqu'à 50 cm ou jusqu'à 1 m du mécanisme d'ouverture de l'ouvrant.The presence detection means are preferably directional or with a narrow detection cone and are for example suitable for detecting a presence over a reduced distance, for example up to 50 cm or up to 1 m from the opening mechanism of the opening.

Le dispositif représenté comporte en outre des moyens de traitement, de mémorisation et de calcul 13 et des moyens de transmission 14.The device shown further comprises processing, storage and calculation means 13 and transmission means 14.

Les moyens de traitement, de mémorisation et de calcul sont par exemple à base d'un microprocesseur ou microcontrôleur comportant un convertisseur analogique numérique et des entrées sorties numériques et de mémoire vive et morte. Les moyens de transmission 14 sont à base de composants radio permettant de transmettre un signal d'alerte sécurisé type AES.The processing, storage and calculation means are for example based on a microprocessor or microcontroller comprising an analog-to-digital converter and digital inputs and outputs and random access and read-only memory. The means of transmission 14 are based on radio components making it possible to transmit a secure alert signal of the AES type.

Les moyens de traitement, de mémorisation et de calcul sont adaptés à traiter les données issues des moyens de détection selon un programme établi dans le dispositif tel que discuté plus bas pour permettre de déclencher une alarme au travers des moyens de transmission 14 vers une centrale d'alarme ou autre centre de surveillance selon un protocole programmé dans le dispositif au niveau des moyens de calcul et de mémorisation.The processing, storage and calculation means are adapted to process the data from the detection means according to a program established in the device as discussed below to allow an alarm to be triggered through the transmission means 14 to a control unit. alarm or other surveillance center according to a protocol programmed in the device at the level of the calculation and storage means.

Le dispositif comporte en outre une source de tension de type pile lithium ou pile à forte capacité pour offrir une durée de fonctionnement importante de plusieurs années. Afin d'améliorer cette durée de fonctionnement, ce dispositif peut être complété ou remplacé par un système de cellule solaire et batterie.The device further comprises a voltage source of the lithium battery or high capacity battery type to provide a long operating life of several years. In order to improve this operating time, this device can be supplemented or replaced by a solar cell and battery system.

Enfin le dispositif peut comporter un témoin lumineux 16 qui va donner une indication visuelle lors de phases de détection choisies.Finally, the device may include an indicator light 16 which will give a visual indication during selected detection phases.

Le but de l'invention est de discriminer les tentatives d'ouverture ayant lieu d'un premier côté de l'ouvrant par rapport aux tentatives d'ouverture ayant lieu de l'autre côté de l'ouvrant.The object of the invention is to discriminate the opening attempts taking place on a first side of the opening from the opening attempts taking place on the other side of the opening.

Pour ce faire, le module 10 est programmé pour discriminer, d'une part un évènement de type détection de mouvement de l'ouvrant avec détection de présence et, d'autre part, un évènement de type détection de mouvement de l'ouvrant sans détection de présence.To do this, the module 10 is programmed to discriminate, on the one hand, an event of the movement detection type of the opening with presence detection and, on the other hand, an event of the movement detection type of the opening without presence detection.

Selon les figures 2 et 3, le boîtier 15 est disposé sur l'ouvrant, porte 20 ou fenêtre 22 à un endroit permettant de détecter de manière sûre une personne manœuvrant le dispositif d'ouverture de l'ouvrant, par exemple la poignée 23, 24 de porte ou de fenêtre, avec les moyens de détection de présence. En particulier, le module peut être positionné où le capteur de mouvement peut être configuré pour ne détecter que des personnes à distance de manœuvre de l'ouvrant notamment face à l'ouvrant.According to figure 2 and 3 , the housing 15 is arranged on the sash, door 20 or window 22 at a place making it possible to reliably detect a person maneuvering the device for opening the sash, for example the handle 23, 24 door or window, with presence detection means. In particular, the module can be positioned where the motion sensor can be configured to detect only people within maneuvering distance of the opening, in particular facing the opening.

Le module comporte un programme d'attente d'événements basse consommation et un système de réveil par exemple par interruptions au niveau d'un microprocesseur ou microcontrôleur des moyens de calcul 13 lorsque les moyens de détection de mouvement 11 sont activés par un mouvement de l'ouvrant.The module includes a program for waiting for low-power events and a wake-up system, for example by interrupts at the level of a microprocessor or microcontroller of the calculation means 13 when the movement detection means 11 are activated by a movement of the opening.

Pour garantir cet aspect faible consommation on utilisera par exemple des architectures hardware basées sur des cœurs ARM Cortex 32 bits très faible tension.To guarantee this low power aspect, for example, hardware architectures based on very low voltage 32-bit ARM Cortex cores will be used.

Le module entre alors dans une procédure de recherche de présence d'un opérateur du côté surveillé par les moyens de détection de présence 12 en activant le capteur infrarouge ou le radar HF.The module then enters a procedure for searching for the presence of an operator on the side monitored by the presence detection means 12 by activating the infrared sensor or the HF radar.

En fonction de la programmation du module selon la détection ou non de présence, soit aucune alarme n'est envoyée soit une alarme est envoyée.Depending on the programming of the module depending on whether or not presence is detected, either no alarm is sent or an alarm is sent.

Un exemple de procédé de surveillance et de détection pour un tel dispositif simple est schématisé en figure 4. Il comporte, après la pose du dispositif sur le côté d'ouverture autorisée de l'ouvrant, une procédure de détection comportant:

  • un mode d'attente 110 comportant l'attente 111 d'un évènement détection d'ouverture et/ou d'un évènement présence;
  • sur l'occurrence d'une détection d'ouverture, une étape 112 de recherche de détection de présence sur le côté d'ouverture autorisée au moyen du détecteur de mouvement permettant une discrimination entre a) détection d'ouverture sans détection de présence et b) détection d'ouverture avec détection de présence;
dans le cas décrit, une étape d'envoi d'alarme 115 dans le cas détection d'ouverture sans détection de présence.An example of a monitoring and detection method for such a simple device is schematized in figure 4 . It includes, after the installation of the device on the authorized opening side of the opening, a detection procedure comprising:
  • a waiting mode 110 comprising waiting 111 for an opening detection event and/or a presence event;
  • on the occurrence of an opening detection, a step 112 of searching for presence detection on the authorized opening side by means of the motion detector allowing discrimination between a) opening detection without presence detection and b ) opening detection with presence detection;
in the case described, a step of sending an alarm 115 in the case of opening detection without presence detection.

Le cas inverse où, sur détection de présence à l'étape 112, une étape d'envoi d'alarme 115' en pointillée est réalisée alors que l'alarme n'est pas envoyée si aucune présence n'est détectée est aussi possible selon la programmation du module.The opposite case where, on detection of presence in step 112, a step of sending an alarm 115′ in dotted lines is carried out while the alarm is not sent if no presence is detected is also possible according to module programming.

Selon la présente invention, le dispositif de la figure 1 est perfectionné en utilisant deux zones de détection principales.According to the present invention, the device of the figure 1 is perfected by using two main detection areas.

En référence à la figure 8 offrant une vue schématique d'un exemple de réalisation d'un dispositif de la présente invention, une première zone de détection principale dite périmètre de confiance est une zone 221 matérialisée par un faisceau ou zone de détection permettant de surveiller un volume de forme conique. La zone ou périmètre de confiance est dirigé vers l'intérieur du local. La détection utilise selon l'exemple un dispositif capteur infrarouge actif avec diodes émissives 19a, 19b et photorécepteur pour détecter une personne s'approchant de l'ouvrant depuis l'intérieur du local à protéger.With reference to the figure 8 offering a schematic view of an exemplary embodiment of a device of the present invention, a first main detection zone called the confidence perimeter is a zone 221 materialized by a beam or detection zone making it possible to monitor a volume of conical shape. The zone or perimeter of confidence is directed towards the interior of the room. The detection uses according to the example an active infrared sensor device with emissive diodes 19a, 19b and photoreceptor to detect a person approaching the opening from inside the room to be protected.

Une seconde zone de détection principale dite périmètre de défiance est réalisée avec un capteur actif ou passif 17 équipé d'un dispositif optique formant un disque de détection 18 au plus près de l'ouvrant.A second main detection zone called the defiance perimeter is made with an active or passive sensor 17 equipped with an optical device forming a detection disc 18 as close as possible to the opening.

Selon une version améliorée, une zone de détection secondaire est réalisée. Cette zone de détection plus large 522 entoure la première pour préciser la détection dans le périmètre de confiance. Pour réaliser cette zone, un capteur passif infrarouge (capteur PIR) 512 est préférablement utilisé ce qui, lorsque la première zone est couverte par un capteur actif infrarouge, permet de travailler sur deux longueurs d'onde différentes ce qui améliore la détection. La détection dans la zone de confiance dans ce cas est validée lorsque les deux détecteurs détectent une présence. Dans la zone de détection commune qui se trouve être la zone 221.According to an improved version, a secondary detection zone is produced. This wider detection zone 522 surrounds the first to specify detection within the confidence perimeter. To achieve this zone, a passive infrared sensor (PIR sensor) 512 is preferably used which, when the first zone is covered by an active infrared sensor, makes it possible to work on two different wavelengths which improves detection. Detection in the confidence zone in this case is validated when the two detectors detect a presence. In the common detection area which happens to be area 221.

Lorsqu'une personne approche, elle est d'abord détectée par le capteur PIR 512 dans la zone 522 et le dispositif se met en attente d'une confirmation de détection avec le capteur infrarouge actif couvrant la zone 221 ce qui correspond aux étapes 1111a, 1111b et 1119a, 1119bde la figure 10A.When a person approaches, he is first detected by the PIR sensor 512 in the zone 522 and the device waits for confirmation of detection with the active infrared sensor covering the zone 221 which corresponds to steps 1111a, 1111b and 1119a, 1119bof the figure 10A .

Le positionnement de la zone de confiance correspondant au cône de détection 221 est matérialisé par exemple en figure 9, cette zone étant dirigée vers l'intérieur du local pour détecter une personne 600 autorisée à manœuvre l'ouvrant.The positioning of the confidence zone corresponding to the detection cone 221 is materialized for example by figure 9 , this zone being directed towards the inside of the room to detect a person 600 authorized to maneuver the opening.

De retour à la figure 8, le dispositif comporte un module 510 réalisé sous forme d'un boîtier destiné à s'appliquer par collage, vissage ou autre méthode sur un côté intérieur d'un ouvrant tout comme le dispositif de la figure 1.Back to the figure 8 , the device comprises a module 510 produced in the form of a box intended to be applied by gluing, screwing or another method on an interior side of an opening, just like the device of the figure 1 .

Le module comporte des moyens 511 de détection de mouvement dudit ouvrant sous forme d'un accéléromètre, comporte un dispositif capteur magnétique 520 qui coopère avec un élément complémentaire sur le dormant pour la détection de l'ouverture et de la fermeture de l'ouvrant et comporte un dispositif de détection de chocs 521 pour déclencher une alarme dans le cas où un intrus frappe sur l'ouvrant.The module comprises means 511 for detecting movement of said opening in the form of an accelerometer, comprises a magnetic sensor device 520 which cooperates with an additional element on the frame for detecting the opening and closing of the opening and includes a shock detection device 521 to trigger an alarm in the event that an intruder knocks on the opening.

Le capteur magnétique de type à effet Hall permet une mesure du champ adaptée à détecter une variation de champ représentative d'une tentative d'intrusion qui va générer une alarmeThe Hall effect type magnetic sensor enables field measurement suitable for detecting a field variation representative of an intrusion attempt which will generate an alarm

Le module comporte en outre selon l'invention plusieurs moyens 512, 200, 220a, 220b de détection de présence, ces moyens étant destinés:

  • pour les moyens 512, 220a, 220b à détecter une présence dans un périmètre de confiance et,
  • pour les moyens 200 à détecter une présence dans un périmètre de défiance.
The module further comprises according to the invention several means 512, 200, 220a, 220b of presence detection, these means being intended:
  • for the means 512, 220a, 220b to detect a presence in a trusted perimeter and,
  • for the means 200 to detect a presence in a perimeter of mistrust.

Le module comporte pour son fonctionnement des moyens 513 de traitement de données traditionnels qui comportent comme le module de la figure 1 un microprocesseur ou microcontrôleur, des entrées/sorties numériques et/ou analogiques, une ou plusieurs mémoires vive et morte ou reprogrammable et qui sont reliés aux périphériques du module, aux moyens de détection 511, 520, 521, 200, 220a, 220b, 512 et au dispositif émetteur radio 514.The module comprises for its operation traditional data processing means 513 which comprise, like the module of the figure 1 a microprocessor or microcontroller, digital and/or analog inputs/outputs, one or more random access and read-only or reprogrammable memories and which are connected to the peripherals of the module, to the detection means 511, 520, 521, 200, 220a, 220b, 512 and to the radio transmitter device 514.

Les dispositifs de détection infrarouge sont préférablement utilisés de manière pulsée pour réduire la consommation électrique du boîtier.The infrared detection devices are preferably used in a pulsed way to reduce the electrical consumption of the box.

La figure 5 montre un détail d'un dispositif 200 de détection infrarouge affecté à la zone de défiance.The figure 5 shows a detail of an infrared detection device 200 assigned to the defiance zone.

Il comporte un capteur infrarouge 211 derrière un dispositif lentille 212 et face à un miroir conique 213.It comprises an infrared sensor 211 behind a lens device 212 and facing a conical mirror 213.

Ce dispositif 200 permet de surveiller une zone 215 sous la forme d'un disque autour du dispositif comme représentée aux figures 6A vue de côté et 6B vue de dessus.This device 200 makes it possible to monitor an area 215 in the form of a disc around the device as shown in figures 6A side view and 6B top view.

Le capteur est positionné sur le dispositif de telle sorte que lorsque ce dernier est fixé sur l'ouvrant, le disque de détection est sensiblement parallèle à l'ouvrant et longe l'ouvrant.The sensor is positioned on the device in such a way that when the latter is fixed on the opening, the detection disc is substantially parallel to the opening and runs along the opening.

Le dispositif 200 utilise un capteur actif et le capteur infrarouge 211 combine un émetteur et un récepteurs décalés selon l'axe du miroir pour ne pas interférer directement l'un avec l'autre.The device 200 uses an active sensor and the infrared sensor 211 combines a transmitter and a receiver offset along the axis of the mirror so as not to interfere directly with each other.

Les figures 6A et 6B représentent en outre le périmètre de détection conique 221 de la zone de confiance réalisé au moyen d'un capteur infrarouge actif 220 comportant une ou plusieurs LED(s) émettrice(s) et un photorécepteur infrarouge.The figures 6A and 6B further represent the conical detection perimeter 221 of the confidence zone produced by means of an active infrared sensor 220 comprising one or more emitting LED(s) and an infrared photoreceptor.

Selon la figure 6A on constate bien que le disque de détection de la zone de défiance est parallèle au dispositif et donc parallèle à l'ouvrant sur lequel le dispositif est apposé. Le périmètre de détection de la zone de confiance est pour sa part dirigé vers le bas à l'intérieur du local à protéger comme aussi représenté en figure 9 ceci afin de détecter des utilisateurs légitimes se dirigeant vers l'ouvrant.According to Figure 6A it can clearly be seen that the detection disc of the defiance zone is parallel to the device and therefore parallel to the opening on which the device is affixed. The detection perimeter of the confidence zone is for its part directed downwards inside the room to be protected as also represented in figure 9 this in order to detect legitimate users heading towards the opening.

Selon la figure 6B vue de dessus, le périmètre de détection de la zone de confiance 221 est par ailleurs réparti de manière égale à droite et à gauche du capteur 220. Des configurations adaptées aux locaux et aux ouvrants peuvent être prévues en modifiant l'angle de détection du capteur dans le plan vertical ou horizontal.According to figure 6B seen from above, the detection perimeter of the confidence zone 221 is moreover distributed equally to the right and to the left of the sensor 220. Configurations adapted to the premises and to the openings can be provided by modifying the detection angle of the sensor in the vertical or horizontal plane.

Comme représenté schématiquement en figure 6C, le capteur de détection de la zone de confiance peut être réalisé avec plusieurs LEDs infrarouges 220a, 220b, 220c couvrant une zone angulaire élargie et un capteur 220d tel qu'une photodiode recevant la lumière infrarouge émise par les LEDs infrarouges et réfléchie par une personne se trouvant dans la zone couverte.As shown schematically in Fig. 6C , the confidence zone detection sensor can be made with several infrared LEDs 220a, 220b, 220c covering a widened angular zone and a sensor 220d such as a photodiode receiving the infrared light emitted by the infrared LEDs and reflected by a person located in the covered area.

Les figures 7A à 7E illustrent les zones de couvertures pour divers types d'ouvrants.The figures 7A to 7E illustrate the coverage areas for various types of openings.

La figure 7A représente une fenêtre à ouverture latérale.The Figure 7A represents a side-opening window.

Lorsque cette dernière est entrouverte comme représenté, le dispositif est actif et surveille la zone de défiance 215 autour de l'ouvrant et la zone de confiance 221 face à l'ouvrant.When the latter is ajar as shown, the device is active and monitors the zone of defiance 215 around the opening and the zone of confidence 221 facing the opening.

Par contre dans le cas où la fenêtre est grande ouverte, le dispositif est désactivé.On the other hand, if the window is wide open, the device is deactivated.

La figure 7B représente une fenêtre à soufflet s'ouvrant par rotation autour d'un axe horizontal inférieur et les zones de surveillance: zone de défiance 215 autour de l'ouvrant et zone de confiance 221 en face de l'ouvrant lorsque la fenêtre est entrouverte.The figure 7B represents a bellows window opening by rotation around a lower horizontal axis and the surveillance zones: zone of defiance 215 around the opening and confidence zone 221 in front of the opening when the window is ajar.

Dans le cas où un intrus passerait la main pour ouvrir ces fenêtres, la détection au niveau de la zone de défiance déclenche l'alarme.In the event that an intruder reaches out to open these windows, detection at the level of the defiance zone triggers the alarm.

Il en est de même pour la fenêtre basculante de la figure 7C et de la fenêtre à l'italienne s'ouvrant autour d'un axe horizontal supérieur de la figure 7D.It is the same for the tilting window of the Fig. 7C and the casement window opening around an upper horizontal axis of the figure 7D .

La figure 7E représente pour sa part une baie vitrée ou une fenêtre coulissante et dans ce cas un dispositif par panneau est utilisé.The figure 7E represents for its part a picture window or a sliding window and in this case a device by panel is used.

Dans ce dernier cas, le dispositif peut rester activé même lorsque la baie vitrée est totalement ouverte.In the latter case, the device can remain activated even when the bay window is completely open.

Comme vu précédemment, la zone de confiance peut comporter deux capteurs permettant de détecter une approche élargie 522 et une approche resserrée 221, la présence étant validée lorsque les deux capteurs détectent une présence c'est-à-dire dans le périmètre commun 221 qui est considéré comme le périmètre de confiance. Ceci permet d'accroître la précision de détection du dispositif.As seen previously, the confidence zone can comprise two sensors making it possible to detect a widened approach 522 and a narrowed approach 221, the presence being validated when the two sensors detect a presence, that is to say in the common perimeter 221 which is considered as the perimeter of trust. This makes it possible to increase the detection accuracy of the device.

En effet, l'utilisation de deux capteurs permet de mieux reconnaître un occupant qui se rapproche de l'ouvrant puis se positionne devant le mécanisme d'ouverture/fermeture ou qui une fois le mécanisme utilisé s'éloigne de l'ouvrant ce qui permet d'obtenir une suite logique d'événements confirmant une action légitime d'actionnement du mécanisme d'ouverture ou de fermeture de l'ouvrant.Indeed, the use of two sensors makes it possible to better recognize an occupant who approaches the opening then positions himself in front of the opening/closing mechanism or who, once the mechanism has been used, moves away from the opening, which allows to obtain a logical sequence of events confirming a legitimate actuation action of the opening or closing mechanism of the leaf.

Au niveau du procédé de détection, le dispositif va discriminer plusieurs situations en fonction, de la position de l'ouvrant et du capteur qui va être le premier activé.At the level of the detection process, the device will discriminate several situations depending on the position of the opening and the sensor which will be the first activated.

On distingue trois situations principales:
Ouvrant fermé/ouvrant entrouvert/ouvrant grand ouvert.Three main situations can be distinguished:
Sash closed/sash ajar/sash wide open.

Dans la situation ouvrant grand ouvert détectée par les capteurs de position de l'ouvrant, le dispositif est désactivé car non utilisable.In the wide-open sash situation detected by the sash position sensors, the device is deactivated because it cannot be used.

Lorsque l'ouvrant est en position entrouverte ou semi/ouvert, le dispositif, contrairement à un dispositif à simple capteur, reste activé et fonctionnel. Il est dans cette situation adapté à discriminer entre un opérateur s'approchant de l'intérieur pour entrer dans la zone de confiance et un intrus passant son bras ou tentant d'entrer ou d'ouvrir l'ouvrant et entrant dans la zone de défiance.When the sash is in the ajar or semi/open position, the device, unlike a simple sensor device, remains activated and functional. In this situation, it is suitable for discriminating between an operator approaching from the inside to enter the confidence zone and an intruder extending his arm or trying to enter or open the sash and entering the distrust zone .

Ceci permet de conserver une protection du local ou du logement fenêtre ou baies vitrées entrouvertes ce qui apporte un confort supplémentaires aux occupants par rapport à un système devant être désactivé dès l'ouverture des ouvrants.This makes it possible to keep the protection of the room or the accommodation with windows or bay windows ajar, which provides additional comfort to the occupants compared to a system that must be deactivated as soon as the openings are opened.

Le module 510 fixé sur un côté intérieur dudit ouvrant permet grâce:

  • aux moyens de détection de mouvement 511, 520, 521 de l'ouvrant,
  • aux premiers moyens de détection de présence formant un faisceau conique 221 définissant un périmètre de confiance englobant une distance de manœuvre par un opérateur du mécanisme d'ouverture 23 de l'ouvrant sur le premier côté de l'ouvrant,
  • aux seconds moyens de détection de présence sur un périmètre 215 de défiance circonscrit autour de l'ouvrant et,
  • aux moyens de traitement de données issues desdits moyens de détection, de mémorisation et de calcul 513 reliés auxdits moyens de détection;
de discriminer:
  1. a - des séquences d'évènements déclencheurs d'alarme comportant:
    • une détection de mouvement de l'ouvrant par les moyens de détection de mouvement sans détection d'opérateur dans ledit périmètre de confiance 221 par les premiers moyens de détection de présence,
    • une détection de présence dans le périmètre de défiance 215 par les seconds moyens de détection de présence sans ou avant détection de présence d'opérateur dans ledit périmètre de confiance par les premiers moyens de détection de présence,
    et,
  2. b - des séquences d'évènements non déclencheurs d'alarme comportant
    • une détection d'un opérateur dans le périmètre de confiance 221 puis une détection de mouvement de l'ouvrant,
    • une détection d'un opérateur dans le périmètre de confiance 221 encadrant une détection de présence dans le périmètre de défiance 215.
The module 510 fixed on an interior side of said opening allows thanks to:
  • to the movement detection means 511, 520, 521 of the opening,
  • to the first presence detection means forming a conical beam 221 defining a confidence perimeter encompassing a maneuvering distance by an operator of the opening mechanism 23 of the opening on the first side of the opening,
  • to the second presence detection means on a perimeter 215 of defiance circumscribed around the opening and,
  • to the means for processing data from said means of detection, storage and calculation 513 connected to said means of detection;
to discriminate:
  1. a - sequences of alarm-triggering events comprising:
    • detection of movement of the opening by the movement detection means without operator detection in said confidence perimeter 221 by the first presence detection means,
    • presence detection in the distrust perimeter 215 by the second presence detection means without or before operator presence detection in said confidence perimeter by the first presence detection means,
    and,
  2. b - sequences of events not triggering an alarm comprising
    • detection of an operator in the trusted perimeter 221 then detection of movement of the opening,
    • a detection of an operator in the perimeter of trust 221 framing a detection of presence in the perimeter of distrust 215.

D'autres séquences peuvent être programmées en fonction de la configuration du local ou des ouvrants, les principaux éléments déclencheurs étant la détection d'une présence dans la zone/le périmètre de défiance ou la détection d'un mouvement de l'ouvrant sans détection de présence dans la zone/le périmètre de confiance.Other sequences can be programmed depending on the configuration of the premises or the openings, the main triggering elements being the detection of a presence in the area/perimeter of mistrust or the detection movement of the sash without presence detection in the trusted zone/perimeter.

Le module est relié à une centrale d'alarme par des moyens de transmission d'alarme activables par les moyens de traitement selon l'occurrence de l'un ou de l'autre type d'événement pour déclencher l'alarme sur détection d'un intrus.The module is connected to an alarm center by means of alarm transmission that can be activated by the processing means depending on the occurrence of one or the other type of event to trigger the alarm on detection of an intruder.

Comme vu précédemment, l'ouvrant 300b, 300c comportant une position stable d'ouverture restreinte, insuffisante pour le passage d'une personne, et une position de pleine ouverture, permettant le passage d'une personne; le dispositif comporte des moyens 511 de détection de position de l'ouvrant adaptés à discriminer les positions de fermeture, d'ouverture restreinte et de pleine ouverture de l'ouvrant pour maintenir la protection du local non seulement lorsque l'ouvrant est fermé mais aussi lorsque l'ouvrant est en ouverture restreinte.As seen above, the opening 300b, 300c comprising a stable position of restricted opening, insufficient for the passage of a person, and a fully open position, allowing the passage of a person; the device comprises means 511 for detecting the position of the sash adapted to discriminate between the closed, restricted opening and full opening positions of the sash to maintain the protection of the room not only when the sash is closed but also when the sash is in restricted opening.

Dans ce cadre, les moyens de traitement, de mémorisation et de calcul 513, reliés aux moyens de détection de position et/ou de mouvement de l'ouvrant sont configurés pour déclencher l'alarme sur détection d'un passage de la position d'ouverture restreinte vers la position de pleine ouverture sans détection, en premier lieu, par les premiers moyens de détection de présence d'un opérateur dans le périmètre de confiance 221. Ceci peut être fait au moyen d'un détecteur d'inclinaison ou d'un accéléromètre.In this context, the processing, storage and calculation means 513, connected to the means for detecting the position and/or movement of the sash are configured to trigger the alarm on detection of a passage from the position of restricted opening towards the fully open position without detection, in the first place, by the first means of detecting the presence of an operator in the confidence perimeter 221. This can be done by means of a tilt detector or an accelerometer.

Les figures 10A à 10C illustrent certains modes de fonctionnement du procédé de détection. Il est à noter que la sortie du mode d'attente notamment peut se faire en recevant une quelconque des information des capteurs qui génèrent des interruptions. La représentation par organigramme séquentiel est donc une représentation simplifiée.The figures 10A to 10C illustrate certain modes of operation of the detection method. It should be noted that the exit from the standby mode in particular can be done by receiving any of the information from the sensors which generate interrupts. The representation by sequential flowchart is therefore a simplified representation.

Le procédé est tel que après la pose du dispositif sur un premier côté de l'ouvrant et activation du dispositif, une procédure de détection est initiée .The method is such that after the installation of the device on a first side of the opening and activation of the device, a detection procedure is initiated.

La procédure de détection comporte selon l'exemple représenté en figure 10A:

  • une première boucle d'attente 1110a qui est activée lorsque l'ouvrant est fermé. Cette boucle comporte l'attente d'un évènement détection de présence 1111 sur les moyens de détection de présence de la zone de confiance Cette détection de présence se base sur une détection par le capteur PIR 1111a suivie et complétée par une détection sur le capteur infrarouge 1111b.
The detection procedure comprises, according to the example shown in figure 10A :
  • a first waiting loop 1110a which is activated when the opening is closed. This loop includes waiting for a presence detection event 1111 on the presence detection means of the trusted zone This Presence detection is based on detection by the PIR sensor 1111a followed and supplemented by detection on the infrared sensor 1111b.

A partir de cette détection, lorsque l'ouvrant est manœuvré, une détection de degré d'ouverture de l'ouvrant 1120, 1117 est initiée. Cette détection permet de discriminer une pleine ouverture 1120 conduisant à une désactivation de l'alarme 1116 d'une ouverture partielle 1117 déclenchant une seconde boucle d'attente 1110b de l'un des événements:

  1. a) détection de mouvement de l'ouvrant 1113b avec détection de présence dans le périmètre de confiance 1119;
  2. b) détection d'ouverture de l'ouvrant sans détection de présence préalable dans le périmètre de confiance 1113a;
  3. c) détection de présence dans le périmètre de défiance 1115.
From this detection, when the opening is operated, detection of degree of opening of the opening 1120, 1117 is initiated. This detection makes it possible to discriminate a full opening 1120 leading to deactivation of the alarm 1116 from a partial opening 1117 triggering a second waiting loop 1110b for one of the events:
  1. a) detection of movement of the opening 1113b with detection of presence in the confidence perimeter 1119;
  2. b) detection of opening of the opening without detection of prior presence in the confidence perimeter 1113a;
  3. c) presence detection in the defiance perimeter 1115.

Dans les cas b) et c), le procédé comporte une étape de déclenchement de l'alarme 1116.In cases b) and c), the method includes a step for triggering the alarm 1116.

Dans le cas a) le procédé comporte une désactivation de l'alarme et un retour à un mode d'attente.In case a) the method comprises a deactivation of the alarm and a return to a standby mode.

Dans le cas où le dispositif comporte des moyens de mesure de l'ouverture de l'ouvrant, le procédé comporte une boucle de détection de mauvaise position entre-ouverte et de déclenchement d'un avertisseur jusqu'à la mise en position entre-ouvert correcte de l'ouvrant. Ceci permet d'entraîner les utilisateurs à positionner l'ouvrant dans la bonne position si celle-ci n'est pas matérialisée par un point dur par exemple.In the case where the device comprises means for measuring the opening of the opening, the method comprises a loop for detecting poor half-open position and triggering a warning device until the half-open position is placed. correct opening. This makes it possible to train users to position the sash in the correct position if the latter is not materialized by a hard point for example.

La figure 10C correspond au cas où le dispositif comporte des moyens de mesure de l'ouverture de l'ouvrant et où le procédé comporte une réactivation de la surveillance sur sortie de la pleine ouverture de l'ouvrant. Dans ce cas le processus retourne à la première boucle d'attente 1110a sur retour 1122 de l'ouvrant à la position fermée et retourne à la seconde boucle d'attente 1110b sur retour 1123 de l'ouvrant à la position entrouverte 1117.The figure 10C corresponds to the case where the device comprises means for measuring the opening of the opening and where the method comprises a reactivation of the monitoring on exit from the full opening of the opening. In this case the process returns to the first waiting loop 1110a on return 1122 of the sash to the closed position and returns to the second waiting loop 1110b on return 1123 of the sash to the half-open position 1117.

Lorsque le dispositif comporte un capteur de choc, une détection de choc 1124 déclenche l'alarme 1116 lors d'une boucle d'attente, la première boucle 1110a sur la figure 10A mais aussi si nécessaire la seconde boucle 1110b.When the device includes a shock sensor, a shock detection 1124 triggers the alarm 1116 during a waiting loop, the first loop 1110a on the figure 10A but also if necessary the second loop 1110b.

La figure 10B représente le cas où le dispositif comportant un capteur magnétique à effet hall, une détection de variation de champ 1130 déclenche l'alarme 1116 ouvrant fermé hors détection de mouvement de l'ouvrant ou détection de présence en zone de confiance.The figure 10B represents the case where the device comprising a hall effect magnetic sensor, a field variation detection 1130 triggers alarm 1116 sash closed not detecting movement of the sash or detecting presence in the confidence zone.

Cette détection se fait dans le cadre de la première boucle 1110a.This detection is done within the framework of the first loop 1110a.

De même la figure 10B représente le cas où le dispositif comportant des moyens de communication LPWAN, le déclenchement de l'alarme 1116 initie un envoi de trame d'alarme 1140 sur le réseau LPWAN utilisé par le dispositif.Likewise the figure 10B represents the case where the device comprising LPWAN communication means, the triggering of the alarm 1116 initiates a sending of an alarm frame 1140 on the LPWAN network used by the device.

Une autre fonctionnalité du dispositif applicable notamment dans le cas d'un dispositif comportant des moyens de détection de brouillage est de pouvoir déclencher une alarme en cas de brouillage radio.Another functionality of the device applicable in particular in the case of a device comprising jamming detection means is to be able to trigger an alarm in the event of radio jamming.

Dans un configuration de base le dispositif constitue un module périphérique d'une centrale d'alarme locale et dialogue avec celle-ci en bande ISM. Dans une version améliorée le dispositif comporte des moyens radio LPWAN, Low Power Wide Area Network c'est-à-dire réseau basse puissance étendu, par exemple un réseau tel que développé par la société Sigfox ou un réseau connu sous le nom de Lora. Dans ce cas, le dispositif est adapté à fonctionner en module autonome pour transmettre des informations et alarmes par le réseau LPWAN vers un centre d'alarme distant en cas de défaut de communication avec la centrale par exemple en cas de brouillage radio. Dans une version totalement autonome, le dispositif n'est pas relié à une centrale d'alarme locale mais uniquement à un centre distant et transmet ses informations et alarmes directement au centre d'alarme distant au travers du réseau LPWAN.In a basic configuration, the device constitutes a peripheral module of a local alarm center and communicates with it in the ISM band. In an improved version, the device comprises LPWAN radio means, Low Power Wide Area Network, that is to say extended low-power network, for example a network as developed by the company Sigfox or a network known by the name of Lora. In this case, the device is adapted to operate as a stand-alone module to transmit information and alarms via the LPWAN network to a remote alarm center in the event of a communication fault with the control unit, for example in the event of radio jamming. In a totally autonomous version, the device is not connected to a local alarm center but only to a remote center and transmits its information and alarms directly to the remote alarm center through the LPWAN network.

Les moyens radio 514 du dispositif comportent selon les versions des moyens radio communicant dans la bande ISM, des moyens radio communicant dans les bandes adaptées aux réseaux LPWAN choisis (bande ISM ou autre).The radio means 514 of the device comprise, depending on the versions, radio means communicating in the ISM band, radio means communicating in the bands adapted to the chosen LPWAN networks (ISM band or other).

Dans une version comportant une détection de brouillage, les moyens radio sont adaptés à détecter un brouillage dans plusieurs bandes dont la bande ISM et les bandes GSM car, un intrus muni d'un dispositif de brouillage, va tenter de brouiller l'ensemble des communications radio autour et dans le local.In a version comprising jamming detection, the radio means are suitable for detecting jamming in several bands including the ISM band and the GSM bands because an intruder equipped with a jamming device will attempt to jam all of the communications radio around and in the room.

Dans ses versions pourvues de moyens de communication avec un centre distant, le dispositif, en cas de détection de brouillage est adapté à envoyer des trames dans des formats et selon des modes de transmission peu sensibles au brouillage tels que bande étroite (narrowband) ou bande à spectre étalé (spread spectrum).In its versions provided with means of communication with a remote center, the device, in the event of interference detection, is suitable for sending frames in formats and according to transmission modes that are not very sensitive to interference, such as narrow band (narrowband) or band spread spectrum.

Pour paramétrer le dispositif ou adapter sa logique de fonctionnement afin de modifier par exemple les niveaux des signaux IR, la sensibilité PIR capté, la vitesse de déplacement, le sens de déplacement, l'angle des zones de défiance ou de confiance, les fréquences de brouillage (jamming en anglais), et les séquences de détection le module du dispositif peut comporter en outre une liaison radio Bluetooth 514a basse puissance ou non permettant de le relier à un outil de programmation externe.To configure the device or adapt its operating logic in order to modify, for example, the levels of the IR signals, the PIR sensitivity captured, the speed of movement, the direction of movement, the angle of the areas of defiance or confidence, the frequencies of jamming, and the detection sequences the module of the device may also comprise a low-power or non-low power Bluetooth 514a radio link enabling it to be connected to an external programming tool.

Le dispositif peut être réalisé dans un module rectangulaire qui se pose soit à l'horizontale soit à la verticale sur une partie d'encadrement de l'ouvrant.The device can be made in a rectangular module which is placed either horizontally or vertically on a frame part of the opening.

Le ou les capteurs des moyens de détection de la zone de confiance pouvant être tournés sur le module pour orienter le faisceau ou le cône vers le bas quelque-soit la position du module sur l'ouvrant.The sensor or sensors of the confidence zone detection means can be turned on the module to direct the beam or the cone downwards whatever the position of the module on the opening.

L'invention n'est pas limitée à l'exemple représenté et, par exemple, dans le cas d'une porte le dispositif peut être programmé pour se désactiver suite à une ouverture de la porte depuis l'intérieur à partir de la zone de confiance et se réactiver lors de la fermeture ultérieure de la porte ce qui permet à l'occupant de sortir puis de rentrer sans devoir désactiver l'alarme périphérique. En outre, les moyens de détection de présence peuvent être orientables et réglables en distance de détection.The invention is not limited to the example shown and, for example, in the case of a door, the device can be programmed to deactivate following opening of the door from the inside from the zone of trust and reactivate when the door is subsequently closed, which allows the occupant to exit and then re-enter without having to deactivate the peripheral alarm. In addition, the presence detection means can be orientable and adjustable in detection distance.
