Definitions

  • Such automatic gates are typically intended to be used within access control systems to reserved areas such as pedestrian zones, building interiors, public transport networks, etc. They allow the filtering of users at the entrance and, where applicable, at the exit of these reserved areas so as to limit access to said reserved areas to authorized users only.
  • the obstacles of these automatic gates are usually positioned in a first position called the obstruction position, in which they extend across an access passage to the reserved area, and are moved by the motor assemblies of these automatic gates in a second position called the opening position away from the passage when an authorized user presents himself at the entrance to the passage.
  • Fraudsters and vandals may attempt to force passage by exerting strong pressure or even kicking (with energy, for example, greater than 300 joules in the case of "Karate Kicking") on obstacles.

  • each door 20 comprises two obstacles 28 as shown on the figure 1 .
  • Each obstacle 28 is constituted by a leaf 34, that is to say a movable panel relative to the frame 24.
  • This leaf 34 is chosen from the following list: tilting leaf, side-removing leaf, pivoting leaf.
  • each obstacle 28 is constituted by a pivoting leaf, that is to say by a leaf mounted to pivot relative to the frame 24 around a vertical axis of rotation D-D'.
  • the leaf 34 is integral with a vertical shaft 60 mounted movable around its axis relative to the frame 24.
  • the door 20 of the gate 14 also comprises, in a known manner, a control device (not shown) adapted to send commands to the motor assembly 22 to open the passage or close the passage.

  • the gate being normally closed, reading a valid ticket gives rise to an opening command. Then, a set of sensors sending signals to the control module which analyzes the passage of the user, the control module triggers the closure, upon detection, based on these signals that the user has passed through the gate.
  • the automatic gate 14 allows users with a transport ticket carried by a contactless card to access public transport networks through the automatic gate 14.
  • the gate 14 comprises a motor assembly 22 for each obstacle 28.

  • the motor assembly 22 comprises an output shaft 62 and a motor 64 for driving the output shaft 62 in rotation around its axis, the output shaft 62 being kinematically linked to the obstacle 28 so that the rotation of the output shaft 62 around its axis causes the obstacle 28 to move between its obstructed and open positions.

  • the memory stores values of modifiable parameters typically include speeds, torques, directions of rotation and/or servo constants in one or more positions of the rotor of the motor 64.
  • the control block 68 is further adapted to collect, all the periods of duration T (T is for example included in the range [50 ms; 200 ms], the current angular position of the shaft 62 measured by the position sensor angular 15.
  • the control block 68 is adapted to control the motor 64, as a function of commands for opening the passage or closing the passage received by the control block 68 from the central computer of the gate, which develops these commands according to the data transmitted on the one hand by the ticket reader, and on the other hand by the sensors which detect the passage of the user (and translated by the control unit 68 into corresponding instructions for maintaining the obstruction position, passage in opening position, angular position values of the shaft 62, angular speed values, torque values on the shaft 62) and furthermore as a function of instructions determined by the motor assembly 22 as described below below in one embodiment of the invention.
  • FIG. 3 illustrates the principle of the servo function of the brushless motor 64 implemented by the control unit 68: it includes two servo loops, function of said “P” instructions: a loop 18 for controlling the torque on the shaft 62 and a loop 17 for controlling the rotation speed and the angular position of the shaft 62.
  • the measurements from the sensor 15 are used to implement these loops.
  • the control block 68 successively collects the angular position measurements carried out by the angular position sensor 15 and gives instructions to the motor to maintain an obstruction position in waiting mode, also called standby mode (the position setpoint controlled, via the servo control of the motor 64, is the closing reference position of the shaft 62 and the torque setpoint commanded, via the servo control of the motor 64, is for example of a minimum value sufficient to maintain the closed obstacle).
  • an obstruction position in waiting mode also called standby mode
  • step 102 based on these collected measurements, the angular difference is determined, as a function of time, between the commanded obstruction position and the actual position. If none of these deviations, in absolute value for example, over the observation time window exceeds a determined threshold, step 101 is repeated. If there is at least one overrun in the observation time window, a step 103 of comparing the profile of the successive angular deviations determined with a set of N typical profile(s) each corresponding to a type of event d The attack on the gate is then implemented.
  • N is greater than or equal to 1, for example equal to 2 or 4.
  • step 103 aims to qualify the aggression.
  • the control block 68 determines, due to the fact that the angular deviation remains greater than a threshold value S1 during a period T1 greater than a threshold duration T0 (type profile 1) (for example equal to s seconds, with s greater than 1), that a forcing type attack takes place.
  • a threshold value S1 for example equal to s seconds, with s greater than 1
  • control block 68 detects that an attack of vandalism type (profile no. 4) is taking place by detecting significant angular deviations, greater than a threshold value S2, itself greater than S1, over impact durations short (less than a threshold duration of T ms, with T less than 900 ms for example, or 700 ms, or 500 ms), which corresponds to violent, rapid and possibly repeated kick type attacks.
  • the two other profiles (profiles no. 2 and 3) take into account, for example, deviation threshold values and intermediate threshold periods.
  • the servomotor 64 follows a torque profile favoring protection against the risk of damage (minimum torque) or on the contrary favoring resistance to the opening attempt (maximum torque). Between these extreme settings, intermediate standard profiles can be provided (for example 2) offering different compromises between self-protection and resistance.
  • a mode of action is thus associated with each typical profile of aggression.
  • the exit from the action modes corresponding to the respective types of aggression is carried out automatically as soon as the angular deviation returns to “usual” values (lower than S1 for example) for a predetermined duration .
  • N is equal to 1 and the only typical aggression profile is for example that corresponding to vandalism, the forcing type aggression being considered to be treated without particular provisions by the torque law of the control which tends to bring the obstacles into the set position.
  • More sophisticated variants can be developed by multiplying the modes, the evolution of torque (and position commands) in these modes, as well as alerts and alarms. For example, in the case of violent shocks repeated at regular intervals, and in a sophisticated version of the system, the opening of the obstacle 28 is controlled by the block of piloting 68 at the moment when the aggressor is going to strike again (possibly with the help of passage sensors), with a view to destabilizing him.
  • the invention thus proposes an automatic gate which makes it possible to resist illegitimate passage attempts, and/or to release passage when security requires it (crowd movement for example), and/or to return to a normal operating state, without damage, when the act of forcing or vandalism has ceased.
  • the invention thus proposes a modular and scalable solution, which optimizes the response by exploiting the chronology of the attack and by qualifying the attack, making it possible to differentiate vandalism (aimed at damaging) from forcing (aimed at obtaining fraudulent passage). ) and implement reaction instructions specific to each case.

  • an output shaft coupled to said obstacle and adapted to be driven in rotation around its axis by said motor assembly to respectively maintain the obstacle in the obstructing position or move the obstacle to free the passage, in accordance with a current instruction among respectively an instruction to obstruct said passage or to release said passage;
  • an electronic control unit adapted to control the motor according to the current setpoint.

De tels portillons automatiques sont typiquement destinés à être utilisés au sein de systèmes de contrôle d'accès à des zones réservées telles que des zones piétonnes, des intérieurs de bâtiments, des réseaux de transport en commun, etc. Ils permettent le filtrage des utilisateurs à l'entrée et, le cas échéant, à la sortie de ces zones réservées de manière à limiter l'accès auxdites zones réservées aux seuls utilisateurs autorisés. A cet effet, les obstacles de ces portillons automatiques sont habituellement positionnés dans une première position dite position d'obstruction, dans laquelle ils s'étendent en travers d'un passage d'accès à la zone réservée, et sont déplacés par les ensembles moteurs de ces portillons automatiques dans une deuxième position dite position d'ouverture à l'écart du passage lorsqu'un utilisateur autorisé se présente à l'entrée du passage.Such automatic gates are typically intended to be used within access control systems to reserved areas such as pedestrian zones, building interiors, public transport networks, etc. They allow the filtering of users at the entrance and, where applicable, at the exit of these reserved areas so as to limit access to said reserved areas to authorized users only. For this purpose, the obstacles of these automatic gates are usually positioned in a first position called the obstruction position, in which they extend across an access passage to the reserved area, and are moved by the motor assemblies of these automatic gates in a second position called the opening position away from the passage when an authorized user presents himself at the entrance to the passage.

Des fraudeurs et vandales peuvent tenter de forcer le passage en exerçant une forte pression, voir des coups de pieds (d'énergie par exemple supérieure à 300 joules dans le cas du "Karaté Kicking") sur les obstacles.Fraudsters and vandals may attempt to force passage by exerting strong pressure or even kicking (with energy, for example, greater than 300 joules in the case of "Karate Kicking") on obstacles.

Outre le besoin pour un portillon automatique de devoir résister aux tentatives de passage illégitimes, il existe également un besoin d'être en mesure de libérer ce passage lorsque la sécurité le nécessite (mouvement de foule par exemple).In addition to the need for an automatic gate to resist illegitimate passage attempts, there is also a need to be able to release this passage when security requires it (crowd movement for example).

Les solutions existantes sont des mécanismes ou des électromécanismes qui libèrent le mouvement des obstacles lorsque la contrainte appliquée sur ceux-ci par le fraudeur dépasse un niveau prédéterminé. Elles apportent une solution passive et binaire peu satisfaisante consistant à résister ou à céder.Existing solutions are mechanisms or electromechanisms which release the movement of obstacles when the constraint applied to them by the fraudster exceeds a predetermined level. They provide an unsatisfactory passive and binary solution consisting of resisting or giving in.

Le portillon automatique 14 représenté en figure 1 comprend un coffre latéral comportant une porte 20 et au moins un ensemble moteur 22.The automatic gate 14 shown in figure 1 comprises a side trunk comprising a door 20 and at least one motor assembly 22.

La porte 20 comprend un bâti 24 définissant un passage 26 s'étendant suivant un axe de circulation longitudinal C-C'. La porte 20 comprend également au moins un obstacle 28 monté mobile par rapport au bâti 24 entre une position d'obstruction, dans laquelle l'obstacle 28 s'étend en travers du passage 26, et une position d'ouverture, dans laquelle l'obstacle 28 est à l'écart du passage 26. De préférence, chaque porte 20 comprend deux obstacles 28 ainsi que cela est représenté sur la figure 1.The door 20 comprises a frame 24 defining a passage 26 extending along a longitudinal circulation axis C-C'. The door 20 also comprises at least one obstacle 28 mounted movable relative to the frame 24 between an obstruction position, in which the obstacle 28 extends across the passage 26, and an open position, in which the obstacle 28 is away from passage 26. Preferably, each door 20 comprises two obstacles 28 as shown on the figure 1 .

Chaque obstacle 28 est constitué par un vantail 34, c'est-à-dire un panneau mobile par rapport au bâti 24. Ce vantail 34 est choisi parmi la liste suivante : vantail basculant, vantail à effacement latéral, vantail pivotant.Each obstacle 28 is constituted by a leaf 34, that is to say a movable panel relative to the frame 24. This leaf 34 is chosen from the following list: tilting leaf, side-removing leaf, pivoting leaf.

Dans le cas particulier considéré, chaque obstacle 28 est constitué par un vantail pivotant, c'est-à-dire par un vantail monté pivotant par rapport au bâti 24 autour d'un axe de rotation vertical D-D'. A cet effet, le vantail 34 est solidaire d'un arbre vertical 60 monté mobile autour de son axe relativement au bâti 24.In the particular case considered, each obstacle 28 is constituted by a pivoting leaf, that is to say by a leaf mounted to pivot relative to the frame 24 around a vertical axis of rotation D-D'. For this purpose, the leaf 34 is integral with a vertical shaft 60 mounted movable around its axis relative to the frame 24.

La porte 20 du portillon 14 comprend également, de manière connue, un dispositif (non représenté) de contrôle adapté pour envoyer à l'ensemble moteur 22 des commandes d'ouverture du passage ou de fermeture du passage. Un tel dispositif comprend typiquement un lecteur de titre adapté pour communiquer avec un titre d'accès d'un utilisateur 26 se présentant à l'entrée du passage, et un calculateur central programmé pour commander ou non la mise en action de l'ensemble moteur 22 en fonction notamment des données lues par le lecteur de titre dans une mémoire du titre d'accès.The door 20 of the gate 14 also comprises, in a known manner, a control device (not shown) adapted to send commands to the motor assembly 22 to open the passage or close the passage. Such a device typically comprises a ticket reader adapted to communicate with an access ticket of a user 26 presenting himself at the entrance to the passage, and a central computer programmed to control or not the activation of the motor assembly 22 depending in particular on the data read by the ticket reader in an access ticket memory.

Ainsi, par exemple, le portillon étant normalement fermé, la lecture d'un ticket valide donne lieu à une commande d'ouverture. Puis, un ensemble de capteurs envoyant des signaux au module de commande qui analyse le passage de l'usager, le module de commande déclenche la fermeture, dès détection, en fonction de ces signaux que l'usager a franchi le portillon.Thus, for example, the gate being normally closed, reading a valid ticket gives rise to an opening command. Then, a set of sensors sending signals to the control module which analyzes the passage of the user, the control module triggers the closure, upon detection, based on these signals that the user has passed through the gate.

Ou encore, par exemple dans un portillon normalement ouvert, c'est la détection d'un début de passage sans titre valide qui entraîne la fermeture par le module de commande, l'ouverture étant commandée par la disparition de la détection de la présence de l'usager à l'entrée du passage, ou la présentation d'un titre valide.Or again, for example in a normally open gate, it is the detection of a start of passage without a valid ticket which causes the closing by the control module, the opening being controlled by the disappearance of the detection of the presence of the user at the entrance to the passage, or the presentation of a valid ticket.

Par exemple, le portillon automatique 14 permet aux usagers munis d'un titre de transport porté par une carte sans contact, d'accéder aux réseaux de transports publics à travers le portillon automatique 14.For example, the automatic gate 14 allows users with a transport ticket carried by a contactless card to access public transport networks through the automatic gate 14.

Le portillon 14 comprend un ensemble moteur 22 pour chaque obstacle 28. Cet ensemble moteur 22 est adapté pour déplacer l'obstacle 28 auquel il est associé entre ses positions d'obstruction et d'ouverture, en fonction de commandes correspondantes reçues en provenance du dispositif (non représenté) de contrôle des autorisations d'accès des utilisateurs et en outre en fonction de consignes déterminées par l'ensemble moteur 22 comme décrit ci-dessous dans un mode de réalisation de l'invention.The gate 14 comprises a motor assembly 22 for each obstacle 28. This motor assembly 22 is adapted to move the obstacle 28 with which it is associated between its obstruction and opening positions, depending on corresponding commands received from the device (not shown) for controlling user access authorizations and furthermore according to instructions determined by the motor assembly 22 as described below in one embodiment of the invention.

A cet effet, comme représenté en figures 1 et 2, l'ensemble moteur 22 comprend un arbre de sortie 62 et un moteur 64 pour entraîner l'arbre de sortie 62 en rotation autour de son axe, l'arbre de sortie 62 étant lié cinématiquement à l'obstacle 28 de sorte que la rotation de l'arbre de sortie 62 autour de son axe entraîne le déplacement de l'obstacle 28 entre ses positions d'obstruction et d'ouverture.For this purpose, as shown in figures 1 And 2 , the motor assembly 22 comprises an output shaft 62 and a motor 64 for driving the output shaft 62 in rotation around its axis, the output shaft 62 being kinematically linked to the obstacle 28 so that the rotation of the output shaft 62 around its axis causes the obstacle 28 to move between its obstructed and open positions.

Le moteur 64 est par exemple de type « brushless ».The motor 64 is for example of the “brushless” type.

L'ensemble moteur 22 comprend un réducteur 66 assurant une réduction de la vitesse de rotation et une augmentation du couple entre le rotor du moteur 64 et l'arbre de sortie 62.The motor assembly 22 includes a reduction gear 66 ensuring a reduction in the rotation speed and an increase in the torque between the rotor of the motor 64 and the output shaft 62.

L'ensemble moteur 22 comprend également un bloc de pilotage 68 pour le pilotage du moteur 64, ledit réducteur 66 et ledit bloc de pilotage 68 formant avec le moteur 64 et l'arbre 62 un motoréducteur 67.The motor assembly 22 also includes a control block 68 for controlling the motor 64, said reduction gear 66 and said control block 68 forming with the motor 64 and the shaft 62 a gear motor 67.

Selon l'invention, l'ensemble moteur 22 comprend en outre un capteur de position angulaire 15, par exemple à effet Hall, adapté pour déterminer la position angulaire de l'arbre de sortie 62 lors de sa rotation autour de l'axe DD' par rapport à une position de référence correspondant à l'obstacle 28 en position d'obstruction. Dans l'exemple considéré, l'ensemble moteur 22 est assemblé à la porte 20 de manière à minimiser les mécanismes intermédiaires entre l'ensemble moteur 22 et l'obstacle 28.According to the invention, the motor assembly 22 further comprises a sensor of angular position 15, for example Hall effect, adapted to determine the angular position of the output shaft 62 during its rotation around the axis DD' relative to a reference position corresponding to the obstacle 28 in the obstructing position. In the example considered, the motor assembly 22 is assembled to the door 20 so as to minimize the intermediate mechanisms between the motor assembly 22 and the obstacle 28.

A cet effet, l'ensemble moteur 22 est accouplé directement à l'obstacle 28, c'est-à-dire qu'il entraîne l'arbre 60 dont est solidaire l'obstacle 28 sans conversion de mouvement entre le mouvement de l'arbre de sortie 62 et le mouvement dudit arbre 60. Ainsi, dans le mode de réalisation particulier considéré, l'arbre de sortie 62 de l'ensemble moteur 22 est coaxial à l'arbre 60 et solidaire de ce dernier.For this purpose, the motor assembly 22 is coupled directly to the obstacle 28, that is to say it drives the shaft 60 to which the obstacle 28 is attached without conversion of movement between the movement of the output shaft 62 and the movement of said shaft 60. Thus, in the particular embodiment considered, the output shaft 62 of the motor assembly 22 is coaxial with the shaft 60 and integral with the latter.

L'ensemble moteur 22 comprend ainsi un dispositif mécanique animé par une motorisation électrique asservie (ensemble servomoteur et réducteur).The motor assembly 22 thus comprises a mechanical device driven by a controlled electric motor (servo motor and reduction gear assembly).

Le bloc de pilotage 68 comprend dans un mode de réalisation une mémoire et un processeur (non représentés). Le bloc de pilotage 68 est en outre adapté pour mettre en oeuvre les étapes qui lui incombent décrites ci-dessous. La mémoire comprend par exemple des instructions logicielles qui, lorsqu'elles sont exécutées sur le processeur, donnent lieu à l'exécution par le bloc de pilotage 68 de ces étapes.In one embodiment, the control block 68 comprises a memory and a processor (not shown). The control block 68 is also adapted to implement the steps assigned to it described below. The memory includes, for example, software instructions which, when executed on the processor, give rise to the execution by the control block 68 of these steps.

Dans un mode de réalisation, la mémoire stocke des valeurs de paramètres modifiables comprennent typiquement des vitesses, des couples, des sens de rotation et/ou des constantes d'asservissement en une ou plusieurs positions du rotor du moteur 64.In one embodiment, the memory stores values of modifiable parameters typically include speeds, torques, directions of rotation and/or servo constants in one or more positions of the rotor of the motor 64.

Le bloc de pilotage 68 est adapté en outre pour collecter, tous les périodes de durée T (T est par exemple comprise dans la plage [50 ms ; 200 ms], la position angulaire courante de l'arbre 62 mesurée par le capteur de position angulaire 15.The control block 68 is further adapted to collect, all the periods of duration T (T is for example included in the range [50 ms; 200 ms], the current angular position of the shaft 62 measured by the position sensor angular 15.

Le bloc de pilotage 68 est adapté pour asservir le moteur 64, en fonction de commandes d'ouverture du passage ou de fermeture du passage reçues par le bloc de pilotage 68 en provenance du calculateur central du portillon, qui élabore ces commandes en fonction des données transmises d'une part par le lecteur de titre, et d'autre part par les capteurs qui détectent le passage de l'usager (et traduites par le bloc de pilotage 68 en consignes correspondantes de maintien de position d'obstruction, de passage en position d'ouverture, de valeurs de position angulaire de l'arbre 62, de valeurs de vitesse angulaire, de valeurs de couple sur l'arbre 62) et en outre en fonction de consignes déterminées par l'ensemble moteur 22 comme décrit ci-dessous dans un mode de réalisation de l'invention.The control block 68 is adapted to control the motor 64, as a function of commands for opening the passage or closing the passage received by the control block 68 from the central computer of the gate, which develops these commands according to the data transmitted on the one hand by the ticket reader, and on the other hand by the sensors which detect the passage of the user (and translated by the control unit 68 into corresponding instructions for maintaining the obstruction position, passage in opening position, angular position values of the shaft 62, angular speed values, torque values on the shaft 62) and furthermore as a function of instructions determined by the motor assembly 22 as described below below in one embodiment of the invention.

La figure 3 illustre le principe de la fonction d'asservissement du moteur brushless 64 mise en oeuvre par le bloc de pilotage 68 : elle comporte deux boucles d'asservissement, fonction desdites consignes « P » : une boucle 18 pour le contrôle du couple sur l'arbre 62 et une boucle 17 pour le contrôle de la vitesse de rotation et de la position angulaire de l'arbre 62. Les mesures du capteur 15 sont utilisées pour mettre en oeuvre ces boucles.There Figure 3 illustrates the principle of the servo function of the brushless motor 64 implemented by the control unit 68: it includes two servo loops, function of said “P” instructions: a loop 18 for controlling the torque on the shaft 62 and a loop 17 for controlling the rotation speed and the angular position of the shaft 62. The measurements from the sensor 15 are used to implement these loops.

Selon l'invention, d'une manière générale, le bloc de pilotage 68 est adapté pour, quand l'obstacle est maintenu en position d'obstruction conformément à une consigne courante d'obstruction du passage, collecter les mesures angulaires effectuées par le capteur 15, pour calculer des variations angulaires dans le temps en fonction desdites mesures collectées et, pour, en fonction desdites variations angulaires calculées, déclencher une action parmi :

  • une augmentation, une réduction ou une limitation du couple appliqué sur l'arbre 62 par le moteur 64 pour maintenir l'obstacle en position d'obstruction, ou
  • une consigne d'ouverture dudit passage.
According to the invention, generally speaking, the control block 68 is adapted to, when the obstacle is maintained in the obstructed position in accordance with a current instruction for obstructing the passage, collect the angular measurements carried out by the sensor 15, for calculate angular variations over time based on said collected measurements and, based on said calculated angular variations, trigger an action among:
  • an increase, reduction or limitation of the torque applied to the shaft 62 by the motor 64 to maintain the obstacle in the obstructing position, or
  • an instruction to open said passage.

Considérons par exemple un mode de réalisation de l'invention décrit maintenant en référence à l'ensemble d'étapes 100 représenté en figure 4, tandis que l'obstacle 28 est maintenu en position d'obstruction par le bloc de pilotage 68 de l'ensemble moteur associé à cet obstacle 28, aucune autorisation de passage n'ayant été déduite de la lecture d'un titre de transport.Consider for example an embodiment of the invention now described with reference to the set of steps 100 represented in figure 4 , while the obstacle 28 is held in the obstructed position by the control block 68 of the motor assembly associated with this obstacle 28, no authorization to pass having been deduced from the reading of a transport ticket.

Dans une étape 101, le bloc de pilotage 68 collecte successivement les mesures de positions angulaires effectuées par le capteur de position angulaire 15 et donne des consignes au moteur pour maintenant une position d'obstruction en mode d'attente, dit encore mode standby (la consigne de position commandée, via l'asservissement du moteur 64, est la position de référence en fermeture de l'arbre 62 et la consigne de couple commandée, via l'asservissement du moteur 64, est par exemple de valeur minimale suffisante pour maintenir l'obstacle fermé).In a step 101, the control block 68 successively collects the angular position measurements carried out by the angular position sensor 15 and gives instructions to the motor to maintain an obstruction position in waiting mode, also called standby mode (the position setpoint controlled, via the servo control of the motor 64, is the closing reference position of the shaft 62 and the torque setpoint commanded, via the servo control of the motor 64, is for example of a minimum value sufficient to maintain the closed obstacle).

Puis dans une étape 102, en fonction de ces mesures collectées, est déterminé l'écart angulaire, en fonction du temps, entre la position d'obstruction commandée et la position réelle. Si aucun de ces écarts, en valeur absolue par exemple, sur la fenêtre temporelle d'observation ne dépasse un seuil déterminé, l'étape 101 est réitérée. S'il existe au moins un dépassement sur la fenêtre temporelle d'observation, une étape 103 de comparaison du profil des écarts angulaires successifs déterminés avec un ensemble de N profil(s) type(s) correspondant chacun à un type d'événement d'agression sur portillon est alors mise en oeuvre.Then in a step 102, based on these collected measurements, the angular difference is determined, as a function of time, between the commanded obstruction position and the actual position. If none of these deviations, in absolute value for example, over the observation time window exceeds a determined threshold, step 101 is repeated. If there is at least one overrun in the observation time window, a step 103 of comparing the profile of the successive angular deviations determined with a set of N typical profile(s) each corresponding to a type of event d The attack on the gate is then implemented.

N est supérieur ou égal à 1, par exemple égal à 2 ou 4.N is greater than or equal to 1, for example equal to 2 or 4.

Ainsi l'étape 103 a pour but de qualifier l'agression.Thus step 103 aims to qualify the aggression.

Par exemple des variations rapides et répétées avec des valeurs d'écart d'angles élevées traduiront une agression relevant du vandalisme, alors qu'un écart angulaire moindre, mais maintenu, traduira un forçage qui peut être lié à un mouvement de foule ou à une fraude.For example, rapid and repeated variations with high angle deviation values will reflect an attack involving vandalism, while a smaller, but maintained, angular deviation will reflect a forcing which can be linked to a crowd movement or to a fraud.

En se référant au graphe en figure 5 représentant les évolutions des écarts angulaires ANG exprimées en 10ème de degrés dans le temps exprimé en ms, le bloc de pilotage 68 détermine, du fait que l'écart angulaire reste supérieur à une valeur seuil S1 pendant une période T1 supérieure à une durée seuil T0 (profil type 1) (par exemple égale à s secondes, avec s supérieure à 1), qu'une agression de type forçage a lieu.Referring to the graph in figure 5 representing the evolutions of the angular deviations ANG expressed in 10th of degrees over time expressed in ms, the control block 68 determines, due to the fact that the angular deviation remains greater than a threshold value S1 during a period T1 greater than a threshold duration T0 (type profile 1) (for example equal to s seconds, with s greater than 1), that a forcing type attack takes place.

Ultérieurement, le bloc de pilotage 68 détecte qu'une agression de type vandalisme (profil n°4) a lieu en détectant des écarts angulaires importants, supérieurs à une valeur seuil S2, elle-même supérieur à S1, sur des durées d'impact courtes (inférieures à une durée seuil de T ms, avec T inférieure à 900 ms par exemple, ou 700 ms, ou 500 ms), ce qui correspond à des attaques de type coup de pieds violents, rapides et éventuellement répétés.Subsequently, the control block 68 detects that an attack of vandalism type (profile no. 4) is taking place by detecting significant angular deviations, greater than a threshold value S2, itself greater than S1, over impact durations short (less than a threshold duration of T ms, with T less than 900 ms for example, or 700 ms, or 500 ms), which corresponds to violent, rapid and possibly repeated kick type attacks.

Dans le cas N = 4, les deux autres profils (profils n°2 et 3) prennent en compte par exemple des valeurs seuils d'écart et des périodes seuils intermédiaires.In the case N = 4, the two other profiles (profiles no. 2 and 3) take into account, for example, deviation threshold values and intermediate threshold periods.

Au cas où la comparaison n'a pu permettre une classification dans l'ensemble de profil type, alors l'étape 101 est réitérée ; dans le cas contraire, une fois le type d'agression déterminé en fonction de l'étape 103 de comparaison, l'étape 104 de déclenchement d'action(s) par le bloc de pilotage 68 en fonction du type d'agression déterminé est mise en oeuvre : une ou des consignes courantes sont alors modifiées par le bloc de pilotage 68, via l'asservissement correspondant du moteur 64, en fonction du type d'agression détecté (ces consignes pouvant être modifiées au cours du temps) ; ces modifications de consignes comprenant :

  • ▪ augmentation de couple pour opposer une résistance (en cas d'agression de type anti-fraude) ; et/ou
  • ▪ réduction ou limitation du couple pour préserver le portillon (si une autoprotection du portillon est souhaitée) ; et/ou
  • ▪ commande de position d'ouverture automatique (protection des personnes).
If the comparison could not allow a classification in the set of standard profiles, then step 101 is repeated; otherwise, once the type of attack has been determined based on comparison step 103, step 104 of triggering action(s) by the control block 68 based on the type of attack determined is implementation: one or more current instructions are then modified by the control block 68, via the corresponding control of the motor 64, depending on the type of attack detected (these instructions can be modified over time); these changes to instructions including:
  • ▪ increased torque to provide resistance (in the event of an anti-fraud type attack); and or
  • ▪ reduction or limitation of the torque to preserve the gate (if self-protection of the gate is desired); and or
  • ▪ automatic opening position control (protection of people).

Suivant les profils types présents dans l'ensemble de profils types, le servomoteur 64 suit un profil de couple privilégiant la protection contre les risques de dommages (couple minimal) ou au contraire privilégiant la résistance à la tentative d'ouverture (couple maximal). Entre ces réglages extrêmes, il peut prévu des profils types intermédiaires (par exemple 2) proposant des compromis différents entre autoprotection et résistance.Depending on the typical profiles present in the set of typical profiles, the servomotor 64 follows a torque profile favoring protection against the risk of damage (minimum torque) or on the contrary favoring resistance to the opening attempt (maximum torque). Between these extreme settings, intermediate standard profiles can be provided (for example 2) offering different compromises between self-protection and resistance.

Un mode d'action est ainsi associé à chaque profil-type d'agression.A mode of action is thus associated with each typical profile of aggression.

Dans une étape 105, consécutive à l'étape 104 ou concomitante, le bloc de pilotage 68 génère des informations et/ou réactions destinées à l'extérieur, telles que des alarmes indiquant le type d'agression, via ses sorties I/O, par exemple :

  • ▪ alarme sonore locale (dissuasion) ; et/ou
  • ▪ signaux lumineux (localisation du portillon parmi d'autres dans une rangée) ; et/ou
  • ▪ transmission d'une alerte au central de la station ou à un agent ; et/ou
  • ▪ transmission d'un repère temporel à un dispositif de vidéo-surveillance...
In a step 105, following step 104 or concomitantly, the control block 68 generates information and/or reactions intended externally, such as alarms indicating the type of attack, via its I/O outputs, For example :
  • ▪ local audible alarm (dissuasion); and or
  • ▪ light signals (location of the gate among others in a row); and or
  • ▪ transmission of an alert to the station central or to an agent; and or
  • ▪ transmission of a time marker to a video surveillance device...

La sortie des modes d'action correspondant aux types d'agression respectifs, par exemple de type forçage ou vandalisme, est effectuée automatiquement dès lors que l'écart angulaire retrouve des valeurs « habituelles » (inférieures à S1 par exemple) pendant une durée prédéterminée.The exit from the action modes corresponding to the respective types of aggression, for example of the forcing or vandalism type, is carried out automatically as soon as the angular deviation returns to “usual” values (lower than S1 for example) for a predetermined duration .

Dans un mode de réalisation, N est égal à 1 et le seul profil d'agression type est par exemple celui correspondant au vandalisme, l'agression de type forçage étant considérée comme traitée sans dispositions particulières par la loi de couple de l'asservissement qui tend à amener les obstacles dans la position de consigne.In one embodiment, N is equal to 1 and the only typical aggression profile is for example that corresponding to vandalism, the forcing type aggression being considered to be treated without particular provisions by the torque law of the control which tends to bring the obstacles into the set position.

Des variantes plus sophistiquées peuvent être développées en multipliant les modes, l'évolution du couple (et des commandes de positions) dans ces modes, ainsi que les alertes et alarmes. Par exemple, dans le cas de chocs violents répétés à intervalles réguliers, et dans une version sophistiquée du système, l'ouverture de l'obstacle 28 est commandée par le bloc de pilotage 68 au moment où l'agresseur va frapper une nouvelle fois (en s'aidant éventuellement des capteurs de passage), en vue de le déstabiliser.More sophisticated variants can be developed by multiplying the modes, the evolution of torque (and position commands) in these modes, as well as alerts and alarms. For example, in the case of violent shocks repeated at regular intervals, and in a sophisticated version of the system, the opening of the obstacle 28 is controlled by the block of piloting 68 at the moment when the aggressor is going to strike again (possibly with the help of passage sensors), with a view to destabilizing him.

Ci-dessous est détaillé la logique à deux profils types d'agression correspondant donc à deux modes d'agression, mis en oeuvre par le bloc de pilotage 68. Cette logique est décrite en référence aux chronogrammes d'écart d'angle ANG en fonction du temps et d la commande de couple CC en fonction du temps, à la figure 5.Below is detailed the logic with two typical aggression profiles corresponding therefore to two aggression modes, implemented by the control block 68. This logic is described with reference to the ANG angle deviation chronograms in function time and DC torque control as a function of time, at Figure 5 .

Mode "attente" (correspondant au mode décrit ci-dessus pour l'état 101)“Wait” mode (corresponding to the mode described above for state 101)

  • si α dépasse le seuil prédéterminé S2 => aller à l'étape V1 du mode "présomption de Vandalisme"
  • si α ne dépasse pas le seuil S2, mais dépasse le seuil prédéterminé S1, inférieur à S2 => aller à l'étape F1 du mode "présomption de Forçage"

  • sinon boucler sur cette étape A0.
A0: Initial state: the motor assembly 22 is in a "waiting" state (also known as "standby"): the doors are closed (Position command = 0 (ie angle deviation as commanded in relation to the position of reference is equal to 0, that is to say that the obstruction position is controlled); Torque command = CC1, low ie minimum to keep the obstacle 28 closed); the actual position angle α of the obstacle is measured continuously in a software loop;
  • if α exceeds the predetermined threshold S2 => go to step V1 of the “presumption of Vandalism” mode
  • if α does not exceed the threshold S2, but exceeds the predetermined threshold S1, lower than S2 => go to step F1 of the “presumption of Forcing” mode
  • if a command is received (for example opening) => exit “wait” mode and execute the command
  • otherwise loop on this step A0.

L'invention propose ainsi un portillon automatique qui permet de résister aux tentatives de passage illégitimes, et/ou de libérer le passage lorsque la sécurité le nécessite (mouvement de foule par exemple), et/ou de revenir à un état normal de fonctionnement, sans dommages, lorsque l'acte de forçage ou le vandalisme a cessé.The invention thus proposes an automatic gate which makes it possible to resist illegitimate passage attempts, and/or to release passage when security requires it (crowd movement for example), and/or to return to a normal operating state, without damage, when the act of forcing or vandalism has ceased.

L'invention permet de détecter et de qualifier un acte violent, et de réagir selon un compromis pertinent entre :

  • l'interdiction de passage des usagers non autorisés,
  • la libération du passage lorsque la sécurité le nécessite,
  • la préservation du matériel contre les dommages,
  • l'alerte graduée et pertinente.

L'invention propose ainsi une solution modulaire et évolutive, qui, optimise la réponse en exploitant la chronologie de l'agression et en qualifiant l'agression, permettant de différencier le vandalisme (visant à endommager) du forçage (visant à obtenir le passage frauduleux) et de mettre en oeuvre des consignes en réaction propres à chaque cas.The invention thus proposes a modular and scalable solution, which optimizes the response by exploiting the chronology of the attack and by qualifying the attack, making it possible to differentiate vandalism (aimed at damaging) from forcing (aimed at obtaining fraudulent passage). ) and implement reaction instructions specific to each case.

L'invention a été décrite ci-dessus relativement à un portillon automatique doté d'un obstacle de type swing.
