ARRIERE PLAN DE L'INVENTIONBACKGROUND OF THE INVENTION

Il existe actuellement des dispositifs permettant de détecter un état d'une porte. Par état d'une porte, on comprend un état de verrouillage, de déverrouillage ou encore d'ouverture et de fermeture de la porte.

DESCRIPTION PLUS DETAILLEEDESCRIPTION DETAILED

La figure 1 illustre un bâtiment 1 comprenant une porte 2 et au moins un élément structurel 3, par exemple un mur. Le bâtiment 1 peut être un logement, par exemple une maison ou un appartement. Il peut également être un entrepôt, un immeuble ou encore juste une pièce par exemple une chambre ou un bureau.The figure 1 illustrates a building 1 comprising a door 2 and at least one structural element 3, for example a wall. Building 1 can be a dwelling, for example a house or an apartment. It can also be a warehouse, a building or just a room for example a bedroom or an office.

La porte 2 comprend par exemple un cadre de porte 2a, une poignée 2b et un système de verrouillage 2c, par exemple une serrure ou un loquet. La porte 2 peut être constituée de n'importe quel matériau. La porte 2 peut également prendre toute forme, et peut notamment être de type « porte battante » ou « porte coulissante ».The door 2 comprises for example a door frame 2a, a handle 2b and a locking system 2c, for example a lock or a latch. The door 2 can be made of any material. The door 2 can also take any form, and can especially be of type "swing door" or "sliding door".

Le bâtiment 1 est pourvu d'un dispositif de supervision 4 d'un état de la porte 2. Le dispositif de supervision 4 est par exemple disposé sur la porte 2. Il peut également être placé sur un élément structurel 3 du bâtiment 1, par exemple à côté de la porte 2.The building 1 is provided with a supervision device 4 of a state of the door 2. The supervision device 4 is for example disposed on the door 2. It can also be placed on a structural element 3 of the building 1, by example next to the door 2.

Pour solidariser le dispositif de supervision 4 au bâtiment 1, un élément de solidarisation 5 peut être prévu, par exemple une bande d'adhésif, qui permet de coller directement le dispositif de supervision 4 sur le bâtiment 1. En variante, le dispositif de supervision 4 peut être solidarisé à une plaque non représentée qui comprend un élément de solidarisation et qui permet de fixer le dispositif de supervision 4 sur la porte 2.To secure the supervision device 4 to the building 1, a fastening element 5 may be provided, for example an adhesive strip, which allows the supervisory device 4 to be directly attached to the building 1. In a variant, the supervision device 4 may be secured to a not shown plate which comprises a securing element and which makes it possible to fix the supervision device 4 on the door 2.

Le dispositif de supervision 4 peut prendre la forme d'une pastille, de petite taille de sorte que l'esthétique générale du bâtiment 1 est conservée.The supervision device 4 can take the form of a small patch, so that the overall aesthetic of the building 1 is preserved.

Comme illustré sur la figure 2, le dispositif de supervision 4 peut comprendre une unité centrale 6, ou « contrôleur 6 » dans la suite de la description. Le contrôleur 6 est par exemple un microcontrôleur ou un microprocesseur. Le contrôleur 6 peut exécuter diverses fonctions de détection de l'état de la porte 2.As illustrated on the figure 2 , the supervision device 4 may comprise a central unit 6, or "controller 6" in the following description. The controller 6 is for example a microcontroller or a microprocessor. The controller 6 can perform various functions of detecting the state of the door 2.

Par « état de la porte », on entend par exemple un état de verrouillage, de déverrouillage, d'ouverture et de fermeture de la porte 2.By "state of the door" is meant, for example, a state of locking, unlocking, opening and closing of the door 2.

Le dispositif de supervision 4 comprend également un capteur d'ondes mécaniques 7, par exemple un accéléromètre, en communication avec le contrôleur 6. Le capteur d'ondes mécaniques 7 est apte à mesurer un signal d'onde mécanique se propageant dans la porte 2 ou dans l'élément structurel 3. Un signal d'onde mécanique est par exemple un signal d'onde vibratoire ou un signal d'onde sonore.The supervision device 4 also comprises a mechanical wave sensor 7, for example an accelerometer, in communication with the controller 6. The mechanical wave sensor 7 is able to measure a mechanical wave signal propagating in the gate 2 or in the structural element 3. A mechanical wave signal is for example a vibratory wave signal or a sound wave signal.

Le capteur d'ondes mécaniques 7 mesure notamment les signaux mécaniques émis par le système de verrouillage 2c afin de détecter un état de verrouillage et de déverrouillage de la porte 2. Le capteur d'ondes mécaniques 7 peut également détecter une ouverture ou une fermeture de la porte 2 par exemple en mesurant un signal d'onde mécanique émis par les gonds de la porte 2, ou la porte 2 frottant sur le sol. Dans le cas où le capteur d'ondes mécaniques 7 est un accéléromètre, une fermeture ou une ouverture de la porte 2 peut notamment être mesurée par la mesure de l'accélération de la porte 2 lorsqu'elle est ouverte ou fermée par quelqu'un.The mechanical wave sensor 7 measures in particular the mechanical signals emitted by the locking system 2c in order to to detect a state of locking and unlocking the door 2. The mechanical wave sensor 7 can also detect an opening or closing of the door 2 for example by measuring a mechanical wave signal emitted by the hinges of the door 2, or door 2 rubbing on the floor. In the case where the mechanical wave sensor 7 is an accelerometer, a closing or opening of the door 2 may in particular be measured by measuring the acceleration of the door 2 when it is opened or closed by someone .

Les signaux d'ondes mécaniques ainsi mesurés par le capteur d'ondes mécaniques 7 sont envoyés au contrôleur 6 qui comprend par exemple un module d'analyse 18. Le module d'analyse 18 comprend par exemple au moins un convertisseur et un filtre afin de rendre lisible le signal.The mechanical wave signals thus measured by the mechanical wave sensor 7 are sent to the controller 6 which comprises, for example, an analysis module 18. The analysis module 18 comprises for example at least one converter and a filter in order to make the signal readable.

Le dispositif de supervision 4 comprend également une mémoire 8 apte à stocker un signal d'onde mécanique dit « signal de référence d'onde mécanique ».The supervision device 4 also comprises a memory 8 capable of storing a mechanical wave signal called a "mechanical wave reference signal".

Ce signal de référence peut correspondre à la signature d'onde mécanique de la porte 2 lorsque le système de verrouillage 2c est actionné. La mémoire 8 peut donc stocker un signal de référence d'onde mécanique correspondant à un déverrouillage de la porte, et un signal de référence d'onde mécanique correspondant à un verrouillage de la porte 2.This reference signal may correspond to the mechanical wave signature of the door 2 when the locking system 2c is actuated. The memory 8 can therefore store a mechanical wave reference signal corresponding to an unlocking of the door, and a mechanical wave reference signal corresponding to a locking of the door 2.

Les signaux signatures stockés dans la mémoire 8 peuvent être transmis à un serveur 6. Les signaux sont par exemple transmis de manière sans fil, via un réseau de type Bluetooth ou Wifi. Le serveur 6 comprend par exemple une base de données dans laquelle sont stockés tous les signaux de référence enregistrés pour chaque porte 2 munie d'un dispositif de supervision 4.The signature signals stored in the memory 8 can be transmitted to a server 6. The signals are for example transmitted wirelessly via a Bluetooth or Wifi type network. The server 6 comprises for example a database in which are stored all the reference signals recorded for each door 2 provided with a supervision device 4.

Dans la suite de la description, le signal d'onde mécanique peut être désigne par le terme « le signal », de même que le signal de référence d'onde mécanique peut être désigné par les termes « signal de référence ».In the following description, the mechanical wave signal may be designated by the term "the signal", just as the mechanical wave reference signal may be designated by the terms "reference signal".

Le signal de référence est par exemple mesuré par le capteur d'ondes mécaniques 7 lors d'une étape d'apprentissage du dispositif de supervision 4.The reference signal is for example measured by the mechanical wave sensor 7 during a learning step of the supervision device 4.

La mémoire 8 et le contrôleur 6 peuvent être en communication, de sorte que lorsque le contrôleur 6 reçoit un signal d'onde mécanique mesuré par le capteur d'ondes mécaniques 7, un module de comparaison 19 compris dans le contrôleur 6 effectue une comparaison entre le signal de référence stocké dans la mémoire 8 et le signal envoyé par le capteur d'ondes mécaniques 7.The memory 8 and the controller 6 can be in communication, so that when the controller 6 receives a mechanical wave signal measured by the mechanical wave sensor 7, a comparison module 19 included in the controller 6 makes a comparison between the reference signal stored in the memory 8 and the signal sent by the mechanical wave sensor 7.

A partir du résultat de la comparaison entre le signal de référence et le signal mesuré par le capteur d'ondes mécaniques 7, le contrôleur 6 est apte à détecter l'état de la porte. Plus précisément, si le capteur d'ondes mécaniques 7 mesure un signal ne correspondant pas au signal de référence du verrouillage de la porte 2, le contrôleur est apte à détecter que la porte n'est pas verrouillée. De même, si le signal mesuré par le capteur d'ondes mécaniques 7 ne correspond pas au signal de référence de déverrouillage de la porte 2, le contrôleur 6 est apte à détecter que la porte 2 n'est pas déverrouillée.From the result of the comparison between the reference signal and the signal measured by the mechanical wave sensor 7, the controller 6 is able to detect the state of the door. More precisely, if the mechanical wave sensor 7 measures a signal that does not correspond to the reference signal of the lock of the door 2, the controller is able to detect that the door is not locked. Similarly, if the signal measured by the mechanical wave sensor 7 does not correspond to the unlocking reference signal of the door 2, the controller 6 is able to detect that the door 2 is not unlocked.

Le dispositif de supervision 4 peut également comprendre une batterie 9. La batterie 9 est par exemple rechargeable. Dans ce cas, le dispositif de supervision 4 est muni d'un port de recharge de la batterie 9. La recharge du dispositif de supervision 4 peut se faire sans le désolidariser du bâtiment 1. En variante, on peut désolidariser le dispositif de supervision 4 durant sa recharge et le repositionner sur le bâtiment 1 ensuite. La batterie 9 et les composants électroniques du dispositif de supervision 4 sont choisis de telle sorte que l'autonomie de la batterie est au moins égale à six mois.The supervision device 4 may also include a battery 9. The battery 9 is for example rechargeable. In this case, the supervision device 4 is provided with a charging port of the battery 9. The charging of the supervision device 4 can be done without separating it from the building 1. As a variant, it is possible to detach the supervision device 4 during its recharge and reposition it on the building 1 then. The battery 9 and the electronic components of the supervision device 4 are chosen so that the battery life is at least equal to six months.

En variante, on peut prévoir que, pour augmenter l'autonomie du dispositif de supervision 4, le contrôleur 6 peut passer en état de sommeil, dans lequel le dispositif de supervision 4 n'est pas apte à détecter l'état de la porte 2, et dans un état actif, dans lequel le dispositif de supervision 4 est apte à détecter l'état de la porte 2.As a variant, it can be provided that, in order to increase the autonomy of the supervision device 4, the controller 6 can go into a state of sleep, in which the supervision device 4 is not able to detect the state of the door 2 , and in an active state, in which the supervision device 4 is able to detect the state of the gate 2.

Le contrôleur 6 peut commander l'activation du dispositif de supervision 4 par exemple au moyen d'un capteur de présence.The controller 6 can control the activation of the supervision device 4 for example by means of a presence sensor.

Le capteur de présence est par exemple un capteur infra-rouge 10. Le capteur infra-rouge 10 peut détecter l'approche d'un objet ou d'une personne. Lorsque le capteur infra-rouge 10 envoie un signal à une entrée de réveil 20 du contrôleur 6, indiquant la présence d'une personne ou d'un objet, le contrôleur 6 passe en état actif afin que le capteur d'ondes mécaniques 7 puisse mesurer un signal d'onde mécanique.The presence sensor is for example an infra-red sensor 10. The infra-red sensor 10 can detect the approach of an object or a person. When the infra-red sensor 10 sends a signal to an alarm input 20 of the controller 6, indicating the presence of a person or an object, the controller 6 goes into the active state so that the mechanical wave sensor 7 can measure a mechanical wave signal.

En variante, on peut prévoir que le dispositif de supervision 4 comprend un microphone 11, apte à envoyer un signal à l'entrée de réveil 20 indiquant l'enregistrement d'un signal sonore au contrôleur 6. De la même manière, lorsque le contrôleur 6 reçoit un tel signal sonore, il passe en état actif.Alternatively, it can be provided that the supervision device 4 comprises a microphone 11, able to send a signal to the alarm input 20 indicating the recording of a sound signal to the controller 6. In the same way, when the controller 6 receives such a sound signal, it goes into active state.

Le dispositif de supervision 4 peut également comprendre une horloge 12. L'horloge 12 est par exemple calibrée de sorte que, si aucun signal n'est mesuré par l'un ou l'autre du capteur infrarouge 10 et du microphone 11 pendant une durée prédéterminée, le contrôleur 6 passe d'un état actif à un état de sommeil.The supervision device 4 may also include a clock 12. The clock 12 is for example calibrated so that, if no signal is measured by either of the infrared sensor 10 and the microphone 11 for a predetermined time, the controller 6 goes from an active state to a sleep state.

Le dispositif de supervision 4 peut également comprendre une interface de communication 13. L'interface de communication 13 est par exemple de type interface radio courte portée de type Bluetooth, Wifi, Sigfox, LoRa ou encore Zigbee. Au moyen de cette interface de communication 13, le contrôleur 6 est apte à délivrer une information relative à l'état de la porte 2.The supervision device 4 may also include a communication interface 13. The communication interface 13 is for example short-range radio interface type Bluetooth, Wifi, Sigfox, LoRa or Zigbee. By means of this communication interface 13, the controller 6 is able to deliver information relating to the state of the door 2.

En relation avec la figure 3, on décrit maintenant un système 14 au sens de l'invention.In relation to the figure 3 a system 14 within the meaning of the invention is now described.

Le système 14 comprend un dispositif de supervision 4 tel que décrit ci-avant. Il comprend en outre un dispositif de communication 15 apte à communiquer avec l'internet. Le dispositif de communication 15 est choisi pour pouvoir communiquer avec l'interface de communication 13.The system 14 comprises a supervision device 4 as described above. It further comprises a communication device 15 able to communicate with the Internet. The communication device 15 is chosen to be able to communicate with the communication interface 13.

L'interface de communication 13 envoie par exemple les données relatives à l'état de la porte 2 au dispositif de communication 15 qui transmet ensuite ces données, via un protocole de transfert de données, par exemple sur un serveur 16. Le serveur 16 peut par exemple stocker le signal de référence mesurer par chaque dispositif afin de former une base de données regroupant une pluralité de signaux de références correspondant à différents types de portes 2.The communication interface 13 for example sends the data relating to the state of the gate 2 to the communication device 15 which then transmits this data, via a data transfer protocol, for example to a server 16. The server 16 can for example, storing the reference signal measured by each device in order to form a database grouping a plurality of reference signals corresponding to different types of gates 2.

Le système 13 peut également comprendre un appareil mobile de communication 17 communiquant avec le dispositif de communication 15. Le dispositif de communication 15 est apte à communiquer à l'appareil de communication mobile les données relatives à l'état de la porte 2.The system 13 may also comprise a mobile communication device 17 communicating with the communication device 15. The communication device 15 is able to communicating to the mobile communication apparatus the data relating to the state of the door 2.

Par exemple, l'appareil mobile de communication 17 comprend une application mobile via laquelle l'utilisateur peut récupérer les données relatives à l'état de la porte.For example, the mobile communication device 17 comprises a mobile application via which the user can retrieve the data relating to the state of the door.

L'appareil de communication mobile 17 peut également être mis en communication avec l'interface de communication 13. L'appareil de communication mobile 17 reçoit par exemple les données d'un seul dispositif de supervision 4. En variante, on peut prévoir que l'appareil de communication mobile 17 peut recevoir les données de plusieurs dispositifs de supervision 4.The mobile communication device 17 can also be placed in communication with the communication interface 13. The mobile communication device 17 receives, for example, the data of a single supervision device 4. As a variant, it is possible to provide that the mobile communication apparatus 17 may receive data from a plurality of supervisory devices 4.

L'appareil de communication mobile 17 est par exemple mis en communication avec l'interface de communication 13 et/ou le dispositif de communication 15 lors de l'étape de calibrage du dispositif de supervision 4.The mobile communication device 17 is for example placed in communication with the communication interface 13 and / or the communication device 15 during the calibration step of the supervision device 4.

En se référant aux figures 4 et 5, un procédé mettant en oeuvre un système 13 comprenant un dispositif de supervision 4 tels que décrit ci-avant est exposé plus en détail.Referring to figures 4 and 5 a method implementing a system 13 comprising a supervisory device 4 as described above is explained in more detail.

Plus précisément, la figure 4 illustre le procédé de calibration du dispositif de supervision 4 par l'utilisateur. La calibration du dispositif de supervision 4 permet, entre autre, de connecter l'interface de communication 13 du dispositif de supervision 4 au dispositif de communication 15. La calibration peut en outre permettre d'effectuer la mise en communication de l'interface de communication 13 et de l'appareil de communication mobile 17.More specifically, the figure 4 illustrates the method of calibration of the supervisory device 4 by the user. The calibration of the supervision device 4 makes it possible, among other things, to connect the communication interface 13 of the supervision device 4 to the communication device 15. The calibration can furthermore make it possible to put the communication interface in communication mode 13 and the mobile communication apparatus 17.

Toujours durant la phase de calibration, l'utilisateur procède par exemple à une étape d'apprentissage. Lors de l'étape d'apprentissage, le dispositif mesure le signal appelé signal de référence afin de le stocker en mémoire 8.Still during the calibration phase, the user proceeds, for example, to a learning step. During the learning step, the device measures the signal called reference signal in order to store it in memory 8.

Plus précisément, l'étape d'apprentissage peut comprendre la mesure de deux signaux de référence.More specifically, the learning step may comprise the measurement of two reference signals.

Notamment, l'utilisateur actionne le système de verrouillage 2c de la porte 2 de sorte que la porte 2 passe d'un état de déverrouillage à un état de verrouillage. Le système de verrouillage 2c émet une onde mécanique correspondant au signal de verrouillage. Le signal de verrouillage est stocké en mémoire sous la forme d'un premier signal de référence.In particular, the user actuates the locking system 2c of the door 2 so that the door 2 goes from an unlocked state to a locked state. The locking system 2c emits a mechanical wave corresponding to the locking signal. The lock signal is stored in memory as a first reference signal.

L'utilisateur peut également actionner le système de verrouillage 2c de la porte 2 de sorte que la porte 2 passe d'un état de verrouillage à un état de déverrouillage. Le système de verrouillage 2c émet une onde mécanique correspondant au signal de déverrouillage. Le signal de déverrouillage est stocké en mémoire sous la forme d'un deuxième signal de référence.The user can also operate the locking system 2c of the door 2 so that the door 2 goes from a locked state to an unlocked state. The locking system 2c emits a mechanical wave corresponding to the unlocking signal. The unlock signal is stored in memory as a second reference signal.

Les signaux de référence peuvent être stockés sur le serveur 16.The reference signals can be stored on the server 16.

A l'étape 20, l'utilisateur place le dispositif de supervision 4 sur le bâtiment 1, par exemple sur l'élément structurel 3 ou la porte 2. A l'étape 21, on procède à la mise en communication d'une part de l'interface de communication 13 et du dispositif de communication 15 mais aussi à la mise en communication de l'appareil de communication mobile 17. Durant cette étape, on peut également collecter des données relatives à l'utilisateur, par exemple son nom, son prénom, le type de porte 2, etc. A l'étape 22, l'utilisateur procède à l'enregistrement des signaux de référence de la porte 2, tel que décrit en référence à la figure 4. Il effectue donc par exemple une action de verrouillage de la porte, puis une action de déverrouillage de la porte 2. Il est entendu que l'utilisateur pourrait procéder dans un ordre différent, ou encore qu'il pourrait enregistrer d'autres signaux de référence, par exemple un signal de référence de l'ouverture de la porte 2.In step 20, the user places the supervisory device 4 on the building 1, for example on the structural element 3 or the door 2. In step 21, the communication is carried out on the one hand of the communication interface 13 and the communication device 15 but also to the communication communication of the mobile communication apparatus 17. During this step, it is also possible to collect data relating to the user, for example his name, his first name, the type of door 2, etc. In step 22, the user proceeds to record the reference signals of the gate 2, such as that described with reference to the figure 4 . For example, it performs a door locking action, then an unlocking action of the door 2. It is understood that the user could proceed in a different order, or that he could record other reference signals. , for example a reference signal of the opening of the door 2.

A l'étape 23, les signaux de référence mesurés sont stockés dans la mémoire 8. Enfin, à l'étape 24, les signaux de référence sont envoyés sur le serveur 16.In step 23, the measured reference signals are stored in the memory 8. Finally, in step 24, the reference signals are sent to the server 16.

La figure 5 illustre les étapes principales du procédé de détection d'un état de la porte 2 par le dispositif de supervision 4, plus précisément un verrouillage ou un déverrouillage de la porte 2.The figure 5 illustrates the main steps of the method of detecting a state of the door 2 by the supervision device 4, more precisely a locking or unlocking of the door 2.

A l'étape 210, le contrôleur 6 est en état de sommeil dans lequel le dispositif de supervision 4 n'est pas apte à mesurer l'état de la porte 2. A l'étape 211, on détermine si un signal est détecté par le capteur de présence comprenant un capteur infrarouge 10 et/ou un microphone 11. Si tel n'est pas le cas, le microcontrôleur reste en état de sommeil. Si un signal est mesuré par le capteur de présence, le contrôleur 6 passe en état actif à l'étape 212, dans lequel le dispositif de supervision 4 est apte à détecter l'état de la porte.In step 210, the controller 6 is in a sleep state in which the supervision device 4 is not able to measure the state of the gate 2. At step 211, it is determined whether a signal is detected by the presence sensor comprising an infrared sensor 10 and / or a microphone 11. If this is not the case, the microcontroller remains in a state of sleep. If a signal is measured by the presence sensor, the controller 6 goes into active state in step 212, in which the supervision device 4 is able to detect the state of the door.

Le capteur infrarouge 10 est calibré de sorte qu'il ne détecte une présence que si la personne ou l'objet est très proche de la porte, par exemple si une personne s'apprête à ouvrir la porte 2. De même, le microphone 11 est calibré de sorte qu'il ne mesure un signal sonore que si la source sonore est très proche. Par exemple, il n'est pas apte à détecter des bruits venant de la rue, ou de locaux voisins (maisons, appartements,...). Le dispositif de supervision 4 peut comprendre uniquement l'un ou l'autre ou l'un et l'autre du capteur infrarouge 10 ou du microphone 11.The infrared sensor 10 is calibrated so that it detects a presence only if the person or object is very close to the door, for example if a person is about to open the door 2. Similarly, the microphone 11 is calibrated so that it only measures a sound signal if the sound source is very close. For example, it is not able to detect noises coming from the street, or from neighboring premises (houses, apartments, ...). The supervision device 4 can include only one or the other or both of the infrared sensor 10 or the microphone 11.

A l'étape 213, le dispositif de supervision 4 détermine si la porte 2 est en position ouverte. Pour cela, le capteur d'ondes mécaniques 7 de type accéléromètre peut être utilisé. Si la porte 2 est ouverte, le contrôleur 6 passe en état de sommeil. Si la porte est fermée, le contrôleur 6 envoie une commande d'activation de l'horloge 12 à l'étape 214.In step 213, the supervision device 4 determines whether the door 2 is in the open position. For this, the mechanical wave sensor 7 type accelerometer can be used. If the door 2 is open, the controller 6 goes into sleep state. If the door is closed, the controller 6 sends a command to activate the clock 12 in step 214.

Lorsque le contrôleur est en état actif, le capteur d'onde mécanique 7 mesure chaque signal d'onde mécanique se propageant dans la porte. Lorsqu'un signal d'onde mécanique est mesuré par le capteur d'onde mécanique 7, tel qu'illustré à l'étape 215, le contrôleur 6 détermine si le signal d'onde mécanique mesuré est un signal de référence.When the controller is in the active state, the mechanical wave sensor 7 measures each mechanical wave signal propagating in the gate. When a mechanical wave signal is measured by the mechanical wave sensor 7, as illustrated in step 215, the controller 6 determines whether the measured mechanical wave signal is a reference signal.

Le contrôleur 6 est en état actif durant une durée prédéterminée et mesurée par l'horloge 10 à l'étape 215. A la fin de cette période prédéterminée, par exemple une période comprise entre quelques secondes et quelques minutes, si aucun signal de référence n'a été détecté, le contrôleur 6 passe en état de sommeil, et stocke dans la mémoire 8 l'état détecté de la porte (étape 216), ici, porte déverrouillée. Si un signal de référence est détecté, ici un signal de référence de verrouillage de la porte 2, l'information relative à l'état de la porte est stockée à l'étape 217.The controller 6 is in active state for a predetermined duration and measured by the clock 10 in step 215.
