Description

SYSTEME DE DETECTION DE TENTATIVE D'INTRUSION A L'INTERIEUR D'UN PERIMETRE DELIMITE PAR UNE CLOTURE INTRUSION TENTATIVE DETECTION SYSTEM WITHIN A CLOSED PERIMETER
DOMAINE TECHNIQUE TECHNICAL AREA
La présente invention à trait à la protection périmétrique de sites sensibles et plus particulièrement à un système de détection de tentative d'intrusion à l'intérieur d'un périmètre délimité par une clôture du type comprenant des panneaux fixés sur des poteaux, ledit système comportant des moyens de détection de chocs et/ou de vibrations connectés à un poste distant. The present invention relates to the perimeter protection of sensitive sites and more particularly to an intrusion attempt detection system inside a perimeter delimited by a fence of the type comprising panels fixed on posts, said system comprising means for detecting shocks and / or vibrations connected to a remote station.
ART ANTERIEUR PRIOR ART
Dans le domaine de la protection périmétrique de sites sensibles tels que des bases militaires, des entrepôts ou des bureaux d'entreprise, par exemple, il est bien connu différents systèmes pour détecter la présence non autorisée de personnes aux abords d'un paramètre délimité par une clôture et/ou pour détecter une tentative d'intrusion à l'intérieur de ce périmètre. In the field of perimeter protection of sensitive sites such as military bases, warehouses or company offices, for example, it is well known various systems for detecting the unauthorized presence of people in the vicinity of a parameter delimited by a fence and / or to detect an intrusion attempt within this perimeter.
Les systèmes les plus répandus comportent des capteurs infrarouges qui sont connectés à un poste distant d'alarme. Ainsi, les capteurs infrarouges forment un réseau délimitant le périmètre à surveiller. Lorsqu'une personne traverse ce périmètre, le faisceau infrarouge est temporairement coupé déclenchant un signal d'alarme.  The most common systems include infrared sensors that are connected to a remote alarm station. Thus, the infrared sensors form a network delimiting the perimeter to be monitored. When a person crosses this perimeter, the infrared beam is temporarily cut off, triggering an alarm signal.
Ce type de système est inutilisable pour surveiller une grande zone extérieure dans la mesure où de nombreux animaux ou insectes sont susceptibles de couper le faisceau infra-rouge déclenchant ainsi un grand nombre d'alarmes intempestives.  This type of system is unusable for monitoring a large outdoor area because many animals or insects are likely to cut the infrared beam thus triggering a large number of nuisance alarms.
On connaît également des systèmes de surveillance comprenant des modules à hyperfréquence, connectées à un poste central distant, qui émettent des ondes dans certaines zones à surveiller. La présence d'une personne dans l'une de ces zones perturbe alors les ondes, la perturbation des ondes étant détectée et procurant l'émission d'un signal d'alarme.  Also known are monitoring systems comprising microwave modules, connected to a remote central station, which emit waves in certain areas to be monitored. The presence of a person in one of these zones then disturbs the waves, the disturbance of the waves being detected and providing the emission of an alarm signal.
De la même manière que précédemment, ce type de système est inutilisable pour surveiller une grande zone extérieure dans la mesure où de nombreux animaux ou insectes sont susceptibles de perturber les ondes déclenchant ainsi un grand nombre d'alarmes intempestives. In the same way as before, this type of system is unusable for monitoring a large outdoor area since many animals or insects are likely to disturb the waves thus triggering a large number of nuisance alarms.
Toutefois, ces systèmes sont essentiellement prévus pour détecter une présence non autorisée d'une personne dans un périmètre déterminé et non pour empêcher physiquement une personne de s'introduire dans ledit périmètre. Ainsi, ces systèmes sont souvent utilisés de façon complémentaire à une clôture comportant usuellement des panneaux tels que des panneaux en fils métalliques « tissés » ou soudés ou des panneaux à fils métalliques « simple torsion, ou des grillages par exemple, fixés sur des poteaux délimitant un périmètre.  However, these systems are essentially designed to detect an unauthorized presence of a person within a given perimeter and not to physically prevent a person from entering the perimeter. Thus, these systems are often used in a complementary manner to a fence usually comprising panels such as "woven" or welded metal wire panels or "single twist" metal wire panels, or grids for example, fixed on poles delimiting a perimeter.
Afin de remédier à ces inconvénients, on a déjà imaginé des moyens de détection de vibrations et/ou de chocs montés sur des panneaux de la clôture. Ces moyens de détection consistent généralement dans des accéléromètres ou dans un système usuellement désigné par le terme « câble-choc » incluant une paire de fils conducteurs prévus pour émettre un signal en cas de vibrations et/ou de chocs sur les panneaux et/ou les poteaux.  In order to remedy these drawbacks, vibration detection and / or shock detection means mounted on panels of the fence have already been devised. These detection means generally consist in accelerometers or in a system commonly referred to as a "shock cable" including a pair of conducting wires provided to emit a signal in the event of vibrations and / or shocks to the panels and / or posts.
C'est le cas notamment du brevet américain US 3,803,548 notamment qui décrit un système d'alarme d'une clôture anti- intrusion. Ledit système comporte d'une part des détecteurs de mouvements piézoélectriques solidarisés aux poteaux de la clôture et connectés à un module central de détection et d'autre part un câble sonde solidarisé à intervalles réguliers aux panneaux de la clôture et connecté à un second module électronique de détection.  This is particularly the case of US Pat. No. 3,803,548 in particular which describes an alarm system of an intrusion-prevention fence. Said system comprises on the one hand piezoelectric motion detectors secured to the fence posts and connected to a central detection module and on the other hand a probe cable secured at regular intervals to the fence panels and connected to a second electronic module detection.
Tous ces systèmes d'alarme présentent l'inconvénient de nécessiter de grandes longueurs de câbles électriques, notamment lorsque le périmètre à surveiller est important et lorsque des caméras de surveillance sont implantées le long de ce périmètre, ce qui grève considérablement les coûts d'installation de ces systèmes d'alarme.  All these alarm systems have the disadvantage of requiring long lengths of electrical cables, especially when the perimeter to be monitored is important and when surveillance cameras are located along this perimeter, which significantly increase the installation costs. of these alarm systems.
Par ailleurs, il est aisé de détecter les « câbles-chocs » et de les neutraliser en les sectionnant de sorte que ces systèmes d'alarme présentent une faible efficacité.  Moreover, it is easy to detect the "shock cables" and neutralize them by cutting them so that these alarm systems have a low efficiency.

DETAILED DESCRIPTION OF THE INVENTION
Par souci de clarté, dans la suite de la description, les mêmes éléments ont été désignés par les mêmes références aux différentes figures. De plus, les diverses vues ne sont pas nécessairement tracées à l'échelle et les dimensions des éléments peuvent avoir été exagérées pour faciliter la compréhension de l'invention. For the sake of clarity, in the remainder of the description, the same elements have been designated by the same references in the various figures. In addition, the various views are not necessarily drawn to scale and the dimensions of the elements may have been exaggerated to facilitate understanding of the invention.
En référence à la figure 1, le système de détection de tentative d'intrusion suivant l'invention comporte une pluralité de boîtiers (1), avantageusement étanches, solidarisés par tous moyens appropriés à un poteau et/ou un panneau d'une clôture comme il sera détaillé un peu plus loin.  With reference to FIG. 1, the intrusion attempt detection system according to the invention comprises a plurality of housings (1), advantageously sealed, secured by any suitable means to a post and / or a panel of a fence such as it will be detailed a little further.
Les panneaux peuvent être de différents types envisageables, rigides ou flexibles, tels que notamment des panneaux soudés, des panneaux en fils métalliques tissés, des panneaux à fils métalliques soudés, des panneaux à fils métalliques dits « à simple torsion », des panneaux grillagés, etc...  The panels can be of different types that can be envisaged, rigid or flexible, such as, in particular, welded panels, woven metal panels, welded metal wire panels, "single-twist" metal wire panels, mesh panels, etc ...
Chaque boîtier (1) comprend une unité centrale de traitement dite CPU (2), telle qu'un microprocesseur par exemple, connectée à au moins une unité de mémoire (3), à au moins un détecteur de chocs et/ou de vibrations (4) et à deux bus de terrain (5) et (6), chaque boîtier (1) étant autonome et connecté à un autre boîtier (1) et/ou à un poste distant constitué d'un ordinateur de type PC par un câble électrique via le bus de terrain (5,6).  Each housing (1) comprises a central processing unit called CPU (2), such as a microprocessor for example, connected to at least one memory unit (3), to at least one shock and / or vibration detector ( 4) and two field buses (5) and (6), each housing (1) being independent and connected to another housing (1) and / or to a remote station consisting of a PC-type computer by a cable electric via the fieldbus (5,6).
Le détecteur de chocs et/ou de vibrations (4) est constitué d'un accéléromètre, de préférence un accéléromètre de type capacitif ; toutefois, il est bien évident que le détecteur de chocs et/ou de vibrations (4) pourra consister dans tout détecteur de chocs et/ou de vibrations bien connu de l'Homme du Métier sans pour autant sortir du cadre de l'invention.  The shock and / or vibration detector (4) consists of an accelerometer, preferably a capacitive type accelerometer; However, it is obvious that the shock and / or vibration detector (4) may consist of any shock and / or vibration detector well known to those skilled in the art without departing from the scope of the invention.
Chaque boîtier (1) est autonome et fonctionne à la manière d'un ordinateur avec son propre système d'exploitation. Ledit système d'exploitation pourra consister dans n'importe quel système d'exploitation connu tel que, par exemple, DOS, OS/2, GNU/Linux, Windows, NetBSD, FreeBSD, OpenBSD, etc .. On entend par système d' exploitation l'ensemble de programmes central d'un appareil informatique qui sert d'interface entre le matériel et les logiciels applicatifs ou entre les middlewares et le matériel informatique. Le système d'exploitation sert ainsi à coordonner l'utilisation du microprocesseur, c'est-à-dire de l'unité centrale de traitement (2), à accorder un certain temps pour l'exécution de chaque processus, à réserver de l'espace dans les mémoires pour les besoins des programmes et à organiser le contenu de la ou des mémoires de masse en fichiers et répertoires. Each box (1) is autonomous and operates in the manner of a computer with its own operating system. Said operating system may consist of any known operating system such as, for example, DOS, OS / 2, GNU / Linux, Windows, NetBSD, FreeBSD, OpenBSD, etc. System operating the central program set of a computing device that interfaces hardware and software applications or between middleware and hardware. The operating system thus serves to coordinate the use of the microprocessor, that is to say the central processing unit (2), to allow a certain time for the execution of each process, to reserve the space in the memories for the needs of the programs and to organize the content of the mass memory or memories into files and directories.
Chaque boîtier (1) est alimenté par un boîtier d'alimentation qui est branché soit sur le secteur soit sur un panneau solaire soit sur une batterie.  Each housing (1) is powered by a power supply that is connected to either the mains or a solar panel or a battery.
Dans cet exemple particulier de réalisation, l'unité de mémoire (3) du boîtier (1) comporte une mémoire RAM (3a) selon l'acronyme anglo-saxon « Random Acess Memory », une mémoire de type EEPROM (3b) selon l'acronyme anglo-saxon « Electrically-Erasable Programmable Read-Only Memory » communément appelée mémoire « flash », une mémoire de type ROM (3ç_) selon l'acronyme anglo-saxon « Read Only Memory » et, accessoirement une mémoire de type SRAM (3d) selon l'acronyme anglo-saxon « Static Random Access Memory ».  In this particular embodiment, the memory unit (3) of the housing (1) comprises a RAM memory (3a) according to the acronym "Random Acess Memory", an EEPROM type memory (3b) according to the 'Electrically-Erasable Programmable Read-Only Memory' acronym commonly known as 'flash' memory, a ROM (3c_) memory according to the acronym "Read Only Memory" and, incidentally, a SRAM-type memory (3d) according to the English acronym "Static Random Access Memory".
Il est bien évident que l'unité de mémoire pourra comporter un ou plusieurs types de mémoire connu de l'homme du métier sans pour autant sortir du cadre de l'invention.  It is obvious that the memory unit may include one or more types of memory known to those skilled in the art without departing from the scope of the invention.
De plus, il va de soi que chaque boîtier (1) pourra ne comporter qu'un bus de terrain (5) ou (6) sans pour autant sortir du cadre de l'invention.  In addition, it goes without saying that each housing (1) may have only one field bus (5) or (6) without departing from the scope of the invention.
Par ailleurs, chaque boîtier (1) comporte une horloge interne (6) et des moyens de synchronisation des horloges (7) des différents boîtiers (1) formant le système de détection suivant l'invention.  Furthermore, each housing (1) comprises an internal clock (6) and clock synchronization means (7) of the various housings (1) forming the detection system according to the invention.
Accessoirement, chaque boîtier (1) comporte un capteur de température (8), un capteur de mesure de la tension (9) dans le câble reliant deux boîtiers (1), un capteur de mesure de l'intensité (10) du courant dans le câble reliant deux boîtiers (1), un capteur de mesure physique interne ou externe (11) permettant de mesurer la radioactivité, un débit, , la température, l'hygrométrie ou similaire, ainsi qu'un bus (12) permettant d'ajouter de nouvelles fonctionnalités audit boîtier (1). Le capteur de la mesure de tension (9) du câble d'alimentation transmet la mesure de la tension à l'unité centrale de traitement (2) qui affiche ladite mesure sur l'un des postes distant et qui compare cette mesure de la tension avec des seuils de tension prédéterminés, un seuil inférieur et/ou un seuil supérieur. Lorsque la tension mesurée est supérieure au seuil supérieur de tension prédéterminé ou inférieure au seuil inférieur de tension prédéterminé, l'unité centrale de traitement (2) génère un message d'alarme qui est transmis à au moins un poste distant. Incidentally, each housing (1) comprises a temperature sensor (8), a voltage measuring sensor (9) in the cable connecting two housings (1), a sensor for measuring the intensity (10) of the current in the cable connecting two housings (1), an internal or external physical measurement sensor (11) for measuring the radioactivity, a flow, the temperature, the hygrometry or the like, and a bus (12) for add new features to the enclosure (1). The sensor of the voltage measurement (9) of the power cable transmits the measurement of the voltage to the central processing unit (2) which displays the said measurement on one of the remote stations and which compares this measurement of the voltage with predetermined voltage thresholds, a lower threshold and / or an upper threshold. When the measured voltage is greater than the predetermined upper voltage threshold or below the predetermined lower voltage threshold, the central processing unit (2) generates an alarm message which is transmitted to at least one remote station.
Lorsqu'un choc est détecté par le détecteur de chocs et/ou de vibrations (4), l'unité centrale de traitement (2) génère un fichier informatique incluant la date et l'heure du choc ainsi que la position du détecteur (4) qui a détecté le choc et/ou les vibrations. Le fichier informatique est alors transmis à l'ordinateur formant le poste distant de telle manière qu'une alarme soit émise sur ledit poste distant. Ladite alarme consiste par exemple dans une alarme sonore.  When an impact is detected by the shock and / or vibration detector (4), the central processing unit (2) generates a computer file including the date and time of the shock as well as the position of the detector (4). ) which has detected shock and / or vibration. The computer file is then transmitted to the computer forming the remote station so that an alarm is sent on said remote station. Said alarm consists for example in an audible alarm.
Selon une première variante d'exécution du système suivant l'invention, en référence à la figure 2, chaque boîtier (1) comporte de la même manière que précédemment une unité centrale de traitement dite CPU (2), telle qu'un microprocesseur par exemple, connectée à au moins une unité de mémoire (3), à au moins un détecteur de chocs et/ou de vibrations (4) et à deux bus de terrain (5) et (6), chaque boîtier (1) étant autonome et connecté à un autre boîtier (1) et/ou à un poste distant constitué d'un ordinateur de type PC par un câble électrique via les bus de terrain (5,6). Chaque boîtier According to a first variant embodiment of the system according to the invention, with reference to FIG. 2, each box (1) comprises in the same way as before a central processing unit called CPU (2), such as a microprocessor by for example, connected to at least one memory unit (3), to at least one shock and / or vibration detector (4) and to two fieldbuses (5) and (6), each housing (1) being autonomous and connected to another housing (1) and / or to a remote station consisting of a PC type computer by an electric cable via the fieldbuses (5,6). Each case
(I) comporte également une horloge interne (6) et des moyens de synchronisation des horloges (7) des différents boîtiers (1) formant le système de détection suivant l'invention et, accessoirement, un capteur de température (8), un capteur de mesure de la tension (9) dans le câble reliant deux boîtiers (1), un capteur de mesure de l'intensité (10) du courant dans le câble reliant deux boîtiers (1), un capteur de mesure physique interne ou externe(I) also comprises an internal clock (6) and means for synchronizing the clocks (7) of the different housings (1) forming the detection system according to the invention and, incidentally, a temperature sensor (8), a sensor for measuring the voltage (9) in the cable connecting two housings (1), a sensor for measuring the current (10) of the current in the cable connecting two housings (1), an internal or external physical measurement sensor
(I I) permettant de mesurer la radioactivité, un débit, la radioactivité, la température, l'hygrométrie ou similaire, ainsi qu'un bus (12) permettant d'ajouter de nouvelles fonctionnalités audit boîtier (1). (I I) for measuring radioactivity, a flow rate, radioactivity, temperature, hygrometry or the like, and a bus (12) for adding new features to said housing (1).
Le boîtier (1) se distingue du boîtier (1) précédemment décrit par le fait qu'il comporte un module d'entrées (3), ledit module comportant n entrées, et un module de sorties (14), ledit module comportant n sorties. Ainsi, différents organes tels qu'un clavier de digicode, un microphone, une sonnette ou un détecteur d'ouverture de porte pourront être connectés aux entrées (13) de chaque boîtier (1) et des organes tels qu'une ventouse, ou une gâche électrique pour l'ouverture d'une porte ou similaire ou un haut parleur pourront être connectés aux sorties (14) dudit boîtier (1). De cette manière, un opérateur pourra déclencher manuellement depuis n'importe quel poste distant l'un des organes connectés sur une des sorties (14) des boîtiers (1). De plus, un poste distant (7) pourra piloter automatiquement les organes connectés sur une des sorties (14) des boîtiers (1) en fonction des informations transmises par les boîtiers (1) via un ou plusieurs organes connectés aux entrées (13) desdits boîtiers (1), par exemple l'ouverture d'une porte en actionnant la ventouse d'une gâche électrique après avoir reçu le code tapé sur le digicode connecté à une entrée (13) d'un boîtier (1). The housing (1) differs from the housing (1) previously described in that it comprises an input module (3), said module having n inputs, and an output module (14), said module having n outputs . Thus, various devices such as a keypad, a microphone, a doorbell or a door opening detector can be connected to the inputs (13) of each housing (1) and organs such as a suction cup, or a electric strike for opening a door or the like or a speaker can be connected to the outputs (14) of said housing (1). In this way, an operator can manually trigger from any remote station one of the members connected to one of the outputs (14) of the housings (1). In addition, a remote station (7) can automatically control the connected devices on one of the outputs (14) of the housings (1) in function of the information transmitted by the housings (1) via one or more members connected to the inputs (13) of said housings (1), for example the opening of a door by actuating the sucker of an electric strike after receiving the code typed on the digital code connected to an input (13) of a housing (1).
D'autres organes tels qu'un appareil de biométrie ou un détecteur de mouvement pourront également être connectés aux entrées (13) des boîtiers (1) sans pour autant sortir du cadre de l'invention.  Other organs such as a biometric apparatus or a motion detector may also be connected to the inputs (13) of the housings (1) without departing from the scope of the invention.
Par ailleurs, le boîtier (1) comporte avantageusement un lecteur de carte mémoire (15) du type carte SDRAM selon l'acronyme anglo-saxon « Synchronous Dynamic Random Access Memory » et une interface série multiplexée (16) IEEE 1394 telle qu'une interface commercialisée sous la référence FIREWIRE® RS 232 par exemple.  Furthermore, the housing (1) advantageously comprises a memory card reader (15) of the SDRAM card type according to the acronym "Synchronous Dynamic Random Access Memory" and a multiplexed serial interface (16) IEEE 1394 such as a interface marketed under the reference FIREWIRE® RS 232 for example.
En référence à la figure 3, selon une autre variante d'exécution du système suivant l'invention, chaque boîtier (1) comporte de la même manière que précédemment une unité centrale de traitement dite CPU (2), telle qu'un microprocesseur par exemple, connectée à au moins une unité de mémoire (3), à au moins un détecteur de chocs et/ou de vibrations (4) et à deux bus de terrain (5) et (6), chaque boîtier (1) étant autonome et connecté à un autre boîtier (1) et/ou à un poste distant (7) constitué d'un ordinateur de type PC par un câble électrique via les bus de terrain (5,6). Chaque boîtier (1) comporte également une horloge interne (6) et des moyens de synchronisation des horloges (7) des différents boîtiers (1) formant le système de détection suivant l'invention et, accessoirement, un capteur de température (8), un capteur de mesure de la tension (9) dans le câble reliant deux boîtiers (1), un capteur de mesure de l'intensité (10) du courant dans le câble reliant deux boîtiers (1), un capteur de mesure physique interne ou externe (11) permettant de mesurer la radioactivité, un débit,, la température, l'hygrométrie ou similaire, ainsi qu'un bus (12) permettant d'ajouter de nouvelles fonctionnalités audit boîtier (1), un module d'entrées (13), un module de sorties (14), un lecteur de carte SDRAM (15) et une interface série multiplexée (16) IEEE 1394 telle qu'une interface commercialisée sous la référence FIREWIRE® RS 232 par exemple.  With reference to FIG. 3, according to another alternative embodiment of the system according to the invention, each box (1) comprises in the same way as before a central processing unit called CPU (2), such as a microprocessor by for example, connected to at least one memory unit (3), to at least one shock and / or vibration detector (4) and to two fieldbuses (5) and (6), each housing (1) being autonomous and connected to another housing (1) and / or to a remote station (7) consisting of a PC-type computer by an electric cable via the field buses (5, 6). Each housing (1) also comprises an internal clock (6) and means for synchronizing the clocks (7) of the various housings (1) forming the detection system according to the invention and, incidentally, a temperature sensor (8), a sensor for measuring the voltage (9) in the cable connecting two housings (1), a sensor for measuring the intensity (10) of the current in the cable connecting two housings (1), an internal physical measurement sensor or external device (11) for measuring radioactivity, a flow rate, temperature, hygrometry or the like, and a bus (12) for adding new functionalities to said housing (1), an input module ( 13), an output module (14), a SDRAM card reader (15) and a multiplexed serial interface (16) IEEE 1394 such as an interface marketed under the reference FIREWIRE® RS 232 for example.
Le boîtier (1) se distingue du boîtier (1) précédemment décrit par le fait qu'il comporte deux modules vidéo (17,18) incluant respectivement un port. De cette manière, une ou deux caméras peuvent être connectées au boîtier (1). Lesdits ports des modules vidéo (17,18) sont aptes à recevoir des caméras CCD qui sont reconnues et installées automatiquement par l'unité centrale de traitement (2) du boîtier (1). Ces caméras pourront avantageusement comporter des moyens d'éclairage tels que des diodes électroluminescentes dites LED selon l'acronyme anglo-saxon « Light Emitting Diode » ou des LED à infrarouge. Ainsi, lorsqu'un choc est détecté par le détecteur de chocs et/ou de vibrations (4), l'unité centrale de traitement (2) active la caméra et enregistre une image ou une succession d'images sous la forme d'un fichier informatique image ou un fichier informatique vidéo. Simultanément, l'unité centrale de traitement (2) génère un fichier informatique d'alarme incluant la date et l'heure du choc ainsi que la position du détecteur (4) qui a détecté le choc et/ou les vibrations. Le fichier informatique d'alarme est alors transmis à l'ordinateur formant le poste distant de telle manière qu'une alarme soit émise sur ledit poste distant . Ladite alarme consiste par exemple dans une alarme sonore. Puis le fichier informatique image ou vidéo enregistré dans l'unité de mémoire s'affiche sur l'écran du poste distant. The housing (1) differs from the housing (1) previously described in that it comprises two video modules (17,18) respectively including a port. In this way, one or two cameras can be connected to the housing (1). Said ports of the video modules (17, 18) are able to receive CCD cameras which are automatically recognized and installed by the central processing unit (2) of the housing (1). These cameras may advantageously include lighting means such as LEDs according to the acronym "Light Emitting Diode" or infrared LEDs. Thus, when an impact is detected by the shock and / or vibration detector (4), the central processing unit (2) activates the camera and records an image or a succession of images in the form of a image computer file or video computer file. Simultaneously, the central processing unit (2) generates a computer alarm file including the date and time of the shock as well as the position of the detector (4) which has detected the shock and / or vibrations. The alarm computer file is then transmitted to the computer forming the remote station so that an alarm is sent on said remote station. Said alarm consists for example in an audible alarm. Then the image or video computer file saved in the memory unit is displayed on the remote station screen.
Il est bien évident que plusieurs caméras pourront être connectées au boîtier (1) et qu'une image ou une séquence vidéo sera alors enregistrée par le boîtier (1) lorsqu'un choc et/ou des vibrations seront détectées. Les dispositifs de prise de vue pourront être activé par l'intermédiaire d'un poste distant.  It is obvious that several cameras may be connected to the housing (1) and an image or a video sequence will be recorded by the housing (1) when shock and / or vibration will be detected. The shooting devices can be activated via a remote station.
De plus, il va de soi que chaque boîtier (1) pourra ne comporter qu'un module vidéo (17) ou (18) sans pour autant sortir du cadre de l'invention.  In addition, it goes without saying that each housing (1) may have only one video module (17) or (18) without departing from the scope of the invention.
Par ailleurs, on observera que les moyens d'éclairage des caméras ne seront activés par l'unité centrale de traitement (2) du boîtier (1) que lorsqu'un choc et/ou des vibrations seront détectés par le détecteur de chocs et/ou de vibrations (4) dudit boîtier (1) afin d'éviter que des insectes nocturnes attirés par la lumière ne viennent devant l'objectif de la caméra.  Furthermore, it will be observed that the camera lighting means will be activated by the central processing unit (2) of the housing (1) only when a shock and / or vibrations are detected by the shock detector and / or vibration (4) of said housing (1) to prevent nocturnal insects attracted by light from coming in front of the camera lens.
De plus, on observera que l'ensemble des caméras pourront être alternativement allumées autour du périmètre afin de procurer des images de chaque secteur dudit périmètre à protéger. Dans la mesure où chaque caméra passe de 100 mA à un peu plus de 1 A lors de l'allumage de LED infrarouge, et où chaque caméra met l/10eme de seconde pour prendre une image, il est possible de faire fonctionner 10 caméras simultanément de telle sorte que, en une seconde, 100 caméras aient pris une image tout en limitant la consommation d'électricité car les LED infrarouges des caméras ne sont activées que lorsqu'une image est acquise par ladite caméra. De cette manière, les LED infrarouges des caméras clignotent, et ne fonctionnent donc pas en continu, évitant ainsi d'attirer les insectes nocturnes et de consommer trop de courant. De manière particulièrement avantageuse, ladite unité centrale de traitement (2) comporte des moyens d'analyse d'images acquises à intervalle régulier par la ou les caméras connectées audit boîtier (1) afin de déterminer si un mouvement à eu lieu dans le champ de vision de la caméra, l'unité centrale de traitement (2) générant un fichier d'alerte qui est alors transmis au poste central en cas de détection d'un mouvement. Lesdits moyens consistent en un algorithme qui compare les images acquises par la caméra à différents moments et détermine toute variation dans les images, une variation importante dans les pixels dans une zone déterminée des images étant considérée comme une intrusion. In addition, it will be observed that all cameras may be alternately lit around the perimeter to provide images of each sector of said perimeter to protect. Insofar as each camera changes from 100 mA to a little more than 1 A when the infrared LED lighting, and where each camera puts / 10 th of a second for taking an image, it is possible to operate camera 10 simultaneously so that, in one second, 100 cameras have taken an image while limiting the power consumption because the infrared LEDs of the cameras are activated only when an image is acquired by said camera. In this way, the infrared LEDs of the cameras flash, and therefore do not work continuously, thus avoiding attracting nocturnal insects and consuming too much current. Particularly advantageously, said central processing unit (2) comprises means for analyzing images acquired at regular intervals by the camera or cameras connected to said housing (1) in order to determine whether a movement has taken place in the field of view. view of the camera, the central processing unit (2) generating an alert file which is then transmitted to the central station in case of detection of a movement. Said means consist of an algorithm that compares the images acquired by the camera at different times and determines any variation in the images, a significant variation in the pixels in a given area of the images being considered as an intrusion.

Le boîtier (1) comporte également deux modules vidéo (17,18) incluant respectivement un port, une carte Ethernet (19), une interface RS 485 (20), également appelée interface EIA 485, permettant des communications « full duplex » ou « half duplex », et/ou une interface radio (21) reliée à une antenne (22) et/ou une interface HD (23) de type SATA selon l'acronyme anglo-saxon « Sériai Advanced Technology Attachment », un récepteur GPS (24) afin de déterminer en temps réel la géolocalisation du boîtier (1), un module GSM (25) afin de permettre des communications sur le réseau GSM et un module audio (26). With reference to FIG. 4, according to another variant of the system according to the invention, each box (1) comprises in the same manner as before a central processing unit called CPU (2), such as a microprocessor by for example, connected to at least one memory unit (3), to at least one shock and / or vibration detector (4), each housing (1) being independent and connected to another housing (1) and / or a remote station (7). Each housing (1) also comprises an internal clock (6) and means for synchronizing the clocks (7) of the various housings (1) forming the detection system according to the invention and, incidentally, a temperature sensor (8), a sensor for measuring the voltage (9) in the cable connecting two housings (1), a sensor for measuring the intensity (10) of the current in the cable connecting two housings (1), an internal physical measurement sensor or (11) for measuring radioactivity, a flow rate, the temperature, hygrometry or the like, and a bus (12) for adding new functionalities to said housing (1), an input module (13), an output module (14), a card reader SDRAM (15) and an IEEE 1394 multiplexed serial interface (16) such as an interface marketed under the reference FIREWIRE® RS 232 for example. The housing (1) also comprises two video modules (17, 18) respectively including a port, an Ethernet card (19), an RS 485 interface (20), also called EIA interface 485, allowing "full duplex" or "full duplex" communications. half duplex ", and / or a radio interface (21) connected to an antenna (22) and / or an HD interface (23) of the SATA type" Sériai Advanced Technology Attachment ", a GPS receiver ( 24) to determine in real time the geolocation of the housing (1), a GSM module (25) to allow communications on the GSM network and an audio module (26).
Ledit boîtier (1) se distingue du boîtier (1) précédemment décrit par le fait que les bus terrain (5,6) ont été substitués par des bus de vidéo-surveillance (27,28) et par le fait qu'il comporte un bus terrain anti- intrusion (29).  Said housing (1) is distinguished from the housing (1) previously described in that the field buses (5, 6) have been substituted by video surveillance buses (27, 28) and by the fact that it comprises a anti-intrusion field bus (29).
Il est bien évident que le boîtier (1) pourra comporter qu'un seul bus vidéo (27) ou (28) sans pour autant sortir du cadre de l'invention.  It is obvious that the housing (1) may comprise only one video bus (27) or (28) without departing from the scope of the invention.
De préférence, chaque boîtier (1) comporte de moyens d'alarme indépendants, tels qu'une alarme lumineuse de type LED, une alarme sonore constituée d'un haut parleur, par exemple, permettant d'émettre une alarme sonore ou visuelle sur le boîtier (1) ayant détecté un choc correspondant à une intrusion, indépendamment de l'alarme transmise aux postes distants.  Preferably, each housing (1) comprises independent alarm means, such as an LED type of light alarm, an audible alarm consisting of a loudspeaker, for example, to emit an audible or visual alarm on the housing (1) having detected a shock corresponding to an intrusion, regardless of the alarm transmitted to the remote stations.
De manière avantageuse, chaque boîtier (1) et/ou chaque poste distant comporte un dispositif dit de « chien de garde » ou « watchdog » bien connu de l'homme du métier permettant d'envoyer une alarme sur le câble à destination des autres postes distants afin de signaler que le boîtier (1) surveillé est bloqué et/ou déclenche une alarme sonore et/ou visuelle sur ledit boîtier (1) bloqué.  Advantageously, each housing (1) and / or each remote station comprises a so-called "watchdog" or "watchdog" device well known to those skilled in the art for sending an alarm on the cable to others remote stations to indicate that the housing (1) monitored is blocked and / or triggers an audible and / or visual alarm on said housing (1) blocked.
Il est bien évident que le boîtier (1) pourra comporter tous moyens appropriés pour permettre une connexion sur un réseau quelconque tel qu'un réseau local par courant porteur en ligne dit CPL, un réseau WI-FI® ou Zigbee® par exemple sans pour autant sortir du cadre de l'invention.  It is obvious that the housing (1) may include any appropriate means to allow connection to any network such as a local network by CPL line power line, a network WI-FI® or Zigbee® for example without as far out of the scope of the invention.
En référence à la figure 5, le système comporte une pluralité de boîtiers (1) connectés en série par des câbles (100) tels que des câbles coaxiaux par exemple, qui procurent simultanément l'alimentation électrique des boîtiers (1) et des différents organes connectés auxdits boîtiers (1) tels que les caméras (101) par exemple et la transmission des fichiers informatiques générés par l'unité centrale de traitement (2) de chaque boîtier (1) vers le ou des postes distants (102). On notera que ces derniers seront connectés sur les câbles au moyen d'une interface USB (103) bien connue de l'Homme du Métier. De plus, l'alimentation est procurée par des boîtiers d'alimentation (104) qui peuvent être connectés au courant du secteur, à des batteries, ou à des panneaux solaires par exemple. With reference to FIG. 5, the system comprises a plurality of housings (1) connected in series by cables (100) such as coaxial cables for example, which simultaneously supply the power supply to the housings (1) and to the various members connected to said housings (1) such as the cameras (101) for example and the transmission of the computer files generated by the central processing unit (2) of each housing (1) to the remote station (s) (102). Note that these will be connected to the cables by means of a USB interface (103) well known to those skilled in the art. In addition, power is provided by power supply boxes (104) that can be connected to the mains power, batteries, or solar panels for example.
On observera que les câbles coaxiaux (100) permettent une transmission des données même si ils sont sectionnés, le débit de transfert des données étant plus faible pour un câble coaxial sectionné par rapport à un câble coaxial non sectionné.  It will be observed that the coaxial cables (100) allow data transmission even if they are sectioned, the data transfer rate being lower for a coaxial cable sectioned with respect to an uncut coaxial cable.
L'un des boîtiers (1) comporte un module d'entrées, ledit module comportant n entrées, et un module de sorties, ledit module comportant n sorties, tel que décrit sur les figures 2,3 et 4. Ainsi, différents organes tels qu'un clavier de digicode (105), un microphone (106), une sonnette (107) ou un détecteur d'ouverture de porte (108) sont connectés aux entrées du boîtier (1) et des organes tels qu'une ventouse ou une gâche électrique (109) pour l'ouverture d'une porte (110) ou similaire et un haut parleur (111) sont connectés aux sorties dudit boîtier (1). De cette manière, un opérateur pourra déclencher manuellement depuis n'importe quel poste distant l'un des organes connectés sur une des sorties des boîtiers (1). De plus, un poste distant (102) pourra piloter automatiquement les organes connectés sur une des sorties des boîtiers (1) en fonction des informations transmises par les boîtiers (1) via un ou plusieurs organes connectés aux entrées desdits boîtiers (1), par exemple l'ouverture d'une porte en actionnant la ventouse d'une gâche électrique après avoir reçu le code tapé sur le digicode connecté à une entrée d'un boîtier (1).  One of the housings (1) comprises an input module, said module having n inputs, and an output module, said module having n outputs, as described in FIGS. 2, 3 and 4. Thus, various devices such as a keypad (105), a microphone (106), a doorbell (107) or a door opening detector (108) are connected to the inputs of the housing (1) and members such as a suction cup or an electric strike (109) for opening a door (110) or the like and a speaker (111) are connected to the outputs of said housing (1). In this way, an operator can manually trigger from any remote station one of the organs connected to one of the outputs of the housings (1). In addition, a remote station (102) can automatically control the members connected to one of the outputs of the boxes (1) according to the information transmitted by the boxes (1) via one or more members connected to the inputs of said boxes (1), by example the opening of a door by operating the sucker of an electric strike after receiving the code typed on the digital code connected to an input of a housing (1).
Chaque boîtier (1) peut avantageusement comprendre des programmes permettant notamment à un boîtier (1) situé près d'une porte de transmettre un script pour qu'un boîtier (1) contigu sur lequel une caméra couvrant la zone du premier boîtier est connectée prenne une image ou une photo lorsque le premier boîtier (1) a détecté une entrée par la porte et/ou un choc. L'image prise par le second boîtier est alors transmise aux postes distants (7). Lorsqu'un boîtier (1) détecte une vibration, ledit boîtier (1) compare les mesures de plusieurs autres boîtiers contigus ou avec un anémomètre connecté à un boîtier contigu afin de discriminer les rafales de vent. En référence à la figure 6, selon une variante d'exécution du système de détection d'intrusion suivant l'invention, le système comporte des boucles dites imbriquées. A cet effet, sur le bus de terrain, entre deux boîtiers (1), une ramification du bus est réalisée. On notera que la ramification du bus pourra présenter une longueur illimitée. Lorsqu'un choc ou une vibration est mesurée par un boîtier (1) positionné sur une telle ramification, le retour sur le bus initial de cette ramification génère des échos dudit choc ou desdites vibrations mesurées par les boîtiers (1) de la boucle situées sur le bus. Les boîtiers (1) filtrent ces échos afin de réaliser des boucles imbriquées de niveau, de longueur et de quantité quelconque. Une telle configuration procure une redondance du bus. Par ailleurs, en cas de coupure du bus sur un segment quelconque, l'ensemble des boîtiers reste opérationnel et peut transmettre les mesures réalisées à n'importe quel poste distant (102). Each housing (1) may advantageously include programs allowing in particular a housing (1) located near a door to transmit a script for a housing (1) contiguous on which a camera covering the area of the first housing is connected. an image or a photo when the first housing (1) has detected an entrance through the door and / or an impact. The image taken by the second housing is then transmitted to the remote stations (7). When a housing (1) detects a vibration, said housing (1) compares the measurements of several other contiguous housings or with an anemometer connected to a contiguous housing in order to discriminate wind gusts. With reference to FIG. 6, according to an alternative embodiment of the intrusion detection system according to the invention, the system comprises so-called nested loops. For this purpose, on the field bus, between two boxes (1), a branch of the bus is made. Note that the branch of the bus may have an unlimited length. When an impact or vibration is measured by a housing (1) positioned on such a branch, the return on the initial bus of this branch generates echoes of said shock or vibrations measured by the housings (1) of the loop located on the bus. The boxes (1) filter these echoes to make nested loops of any level, length and quantity. Such a configuration provides redundancy of the bus. Moreover, in the event of a bus failure on any segment, all the boxes remain operational and can transmit the measurements made to any remote station (102).
La comparaison des mesures réalisées par les différents boîtiers (1) permet de discriminer des signaux générés par le vent ou d'indiquer l'étendue d'une intrusion dans le cas du fauchage de la clôture par une voiture ou un camion par exemple.  The comparison of the measurements made by the different housings (1) makes it possible to discriminate signals generated by the wind or to indicate the extent of an intrusion in the case of mowing the fence by a car or a truck, for example.
Par ailleurs, la comparaison des horloges interne des boîtiers (1) permet de donner une direction et une vitesse de propagation des vibrations détectées sur la clôture.  Moreover, the comparison of the internal clocks of the housings (1) makes it possible to give a direction and a speed of propagation of the vibrations detected on the fence.
En référence aux figures5, 6 et 7A à 7C, les boîtiers (1) communiquent entre eux par l'intermédiaire du bus de terrain. Lorsqu'un choc, des vibrations ou un bruit est détecté par l'un des boîtiers (1), les boîtiers (1) contigus sont interrogés. La comparaison de tous les signaux transmis par les boîtiers (1) donnent une information supplémentaire intéressante. En référence aux figures 7 A et 7B, lorsqu'un choc intervient sur un panneau de la clôture sur lequel est fixé un boîtier (1), il apparaît que les boîtiers (1) mesurent des vibrations plus faibles que celles du premier boîtier (1) de sorte que ces derniers sont discriminés pour la localisation du choc sur la clôture. En référence à la figure 7C, lorsqu'un choc intervient sur un panneau de la clôture ne comportant pas de boîtier (1), il apparaît que les boîtiers (1) les plus proches du choc mesurent des vibrations sensiblement égales et que les boîtiers les plus éloignés du choc ne mesurent que des vibrations très faibles. Les mesures des boîtiers (1) les plus proches du choc sont alors retenues pour déterminer la position du choc sur la clôture alors que les autres mesures des boîtiers (1) les plus éloignés sont discriminées.  With reference to FIGS. 5, 6 and 7A to 7C, the housings (1) communicate with each other via the fieldbus. When shock, vibration or noise is detected by one of the housings (1), the contiguous housings (1) are interrogated. The comparison of all the signals transmitted by the boxes (1) gives additional interesting information. With reference to FIGS. 7A and 7B, when an impact occurs on a panel of the enclosure on which a housing (1) is fixed, it appears that the housings (1) measure lower vibrations than those of the first housing (1). ) so that the latter are discriminated for the location of the shock on the fence. With reference to FIG. 7C, when an impact occurs on a panel of the enclosure that does not include a housing (1), it appears that the housings (1) closest to the shock measure substantially equal vibrations and that the housings farther away from the shock measure only very weak vibrations. The measurements of the housings (1) closest to the shock are then retained to determine the position of the impact on the fence while the other measurements of the housings (1) furthest apart are discriminated.
De cette manière, il est possible de diminuer le nombre de boîtier (1) le long de la clôture et de réaliser une clôture à partir de poteaux régulièrement espacés et d'un grillage d'un seul tenant. Ainsi en référence à la figure 8, la clôture est constituée de poteaux (200) régulièrement espacés et d'un grillage semi-rigide (201) d'un seul tenant, les poteaux (200) situés aux extrémités comportant des moyens de mise sous tension du grillage et des barres de renfort (202). In this way, it is possible to reduce the number of casings (1) along the fence and to make a fence from evenly spaced posts and a fence in one piece. Thus, with reference to FIG. 8, the fence consists of poles (200) regularly spaced apart and a semi-rigid grid (201) in one piece, the poles (200) located at the ends having means for putting under tension of the mesh and reinforcement bars (202).
Par ailleurs, en référence à la figure 9, les vantaux (203) des portails de la clôture sont constitués d'un cadre (204) sensiblement rectangulaire sur lequel est tendu un grillage semi-rigide (201), ledit cadre comportant des barres de renfort (205).  Furthermore, with reference to FIG. 9, the leaves (203) of the gates of the fence consist of a substantially rectangular frame (204) on which is stretched a semi-rigid grid (201), said frame comprising bars of reinforcement (205).
De manière similaire, en référence à la figure 10, les portillons (206) de la clôture sont constitués d'un cadre (207) sensiblement rectangulaire sur lequel est tendu un grillage semi-rigide (201), ledit cadre comportant des barres de renfort (208).  Similarly, with reference to FIG. 10, the gates (206) of the fence consist of a substantially rectangular frame (207) on which is stretched a semi-rigid grid (201), said frame comprising reinforcing bars. (208).
Selon une autre variante d'exécution du système suivant l'invention, en référence à la figure 11, le système comporte deux réseaux indépendants, un premier réseau (209) constitué de boîtiers (1) reliés par un câble pour bus de terrain des boîtiers (1) tels que décrits aux figures 1 à 3, et un second réseau (210) constitué de boîtiers (1) reliés par un câble pour bus vidéo des boîtiers (1) tels que décrit à la figure 4. Sur chacun de ces réseaux (209,210), des boîtiers (1) sont montés en série et sont aptes à recevoir différents organes tels qu'un clavier de digicode (105), un microphone (106), une sonnette (107) ou un détecteur d'ouverture de porte connectés aux entrées du boîtier (1), des organes tels qu'une ventouse magnétique ou une gâche électrique (108) pour l'ouverture d'une porte (109) ou similaire et un haut parleur (110) connectés aux sorties dudit boîtier (1), des caméras (101), des capteurs (211) montés en série par exemple ou tout autre organe. Chaque réseau (209,210) comporte par ailleurs un ou plusieurs postes distants (102) connectés au câble au moyen d'une interface USB (103).  According to another variant embodiment of the system according to the invention, with reference to FIG. 11, the system comprises two independent networks, a first network (209) consisting of housings (1) connected by a cable for fieldbus enclosures (1) as described in Figures 1 to 3, and a second network (210) consisting of housings (1) connected by a video bus cable housings (1) as described in Figure 4. On each of these networks (209,210), housings (1) are mounted in series and are adapted to receive different organs such as a keypad (105), a microphone (106), a doorbell (107) or a door opening detector connected to the inputs of the housing (1), members such as a magnetic sucker or an electric strike (108) for opening a door (109) or the like and a speaker (110) connected to the outputs of said housing ( 1), cameras (101), sensors (211) connected in series for example or any other organ. Each network (209, 210) also has one or more remote stations (102) connected to the cable by means of a USB interface (103).
De manière avantageuse, le système suivant l'invention comporte un câble bus terrain (212) réalisant une passerelle entre le bus terrain et le bus vidéo des deux réseaux, ainsi qu'une centrale dite hors site (213) apte à communiquer avec un boîtier passerelle central/bus terrain (214) connecté au câble pour bus terrain du réseau (209) et/ou avec un boîtier passerelle central/bus vidéo (215) connecté au câble pour bus vidéo du réseau (210).  Advantageously, the system according to the invention comprises a fieldbus cable (212) providing a gateway between the fieldbus and the video bus of the two networks, as well as a so-called offsite power plant (213) able to communicate with a box a central gateway / fieldbus (214) connected to the network fieldbus cable (209) and / or a central gateway / video bus box (215) connected to the network video bus cable (210).
En outre, le système suivant l'invention permet la détection et la localisation d'une explosion à l'intérieur ou à proximité du périmètre délimité par la clôture munie de boîtiers (1) suivant l'invention, la détection et la localisation de cris, ainsi que la discrimination de crissement de pneus particulièrement utile dans un parking, le couplage d'images et de déclenchement d'événement et la détection de mouvement par stéréoscopie ou stéréovidéo notamment. In addition, the system according to the invention makes it possible to detect and locate an explosion inside or near the perimeter delimited by the fence provided with housings (1) according to the invention, the detection and localization of screams. , as well as tire squeal discrimination particularly useful in a parking lot, coupling of images and event triggering and motion detection by stereoscopy or stereovideo in particular.
La détection et la localisation d'une explosion est réalisée par la mesure de sons réalisée par au moins deux boîtiers (1) respectivement munis d'un microphone, les boîtiers (1) ayant leurs horloges internes parfaitement synchronisées, puis par triangulation, la position de la source du son est déterminée soit par un poste distant (7) soit par l'un des boîtiers (1) qui exécute un algorithme de triangulation à partir des sons enregistrés, et plus particulièrement de leur durée, de leur intensité et du moment de la détection. Une telle détection et localisation d'une explosion ou d'un coup de feu est particulièrement intéressante pour la sécurisation de camps militaires en opération extérieur (OPEX) mais aussi de sites de l'industrie chimique, pétrochimique.  Detection and localization of an explosion is carried out by measuring sounds made by at least two housings (1) respectively provided with a microphone, the housings (1) having their internal clocks perfectly synchronized, then by triangulation, the position of the sound source is determined either by a remote station (7) or by one of the boxes (1) which executes a triangulation algorithm from the recorded sounds, and more particularly of their duration, their intensity and the moment detection. Such detection and location of an explosion or a shot is particularly interesting for the security of military camps in foreign operation (OPEX) but also sites of the chemical and petrochemical industry.
La détection et la localisation de cris s'effectue de la même manière que la détection et la localisation d'une explosion, les crissements de pneu étant discriminés dès lors que le son détecté est localisé sur une voie de roulement préalablement identifiée par exemple.  The detection and location of shouting is carried out in the same manner as the detection and location of an explosion, tire squeaks being discriminated as soon as the detected sound is located on a track previously identified, for example.
On notera que la précision de la localisation du son, qu'il s'agisse d'une explosion, d'un coup de feu, d'un cri ou de crissement de pneu dépendra notamment de la précision de la synchronisation des horloges internes des boîtiers (1) du système.  Note that the accuracy of the location of the sound, whether it is an explosion, a shot, a shout or squeal tire will depend in particular on the accuracy of the synchronization of the internal clocks of housings (1) of the system.
Accessoirement, chaque boîtier (1) pourra comporter un récepteur radio, non représenté sur les figures, afin de permettre de localiser par triangulation, de manière bien connue, une personne utilisant une radio ou un téléphone portable dans le périmètre sécurisé ou à proximité de ce dernier.  Incidentally, each housing (1) may include a radio receiver, not shown in the figures, to allow to locate by triangulation, in a well-known manner, a person using a radio or a mobile phone in the secure perimeter or near this latest.
De manière avantageuse, lorsqu'une intrusion ou un événement particulier est détecté par au moins un boîtier (1), une image témoin est comparée avec au moins une image acquise par l'un des boîtiers (1) couvrant la zone correspondant à la localisation de l'intrusion ou de l'événement, ladite image témoin et la ou les images acquises étant visualisées sur l'écran d'au moins un poste distant (102).  Advantageously, when a particular intrusion or event is detected by at least one housing (1), a reference image is compared with at least one image acquired by one of the housings (1) covering the area corresponding to the location. intrusion or event, said control image and the acquired image or images being displayed on the screen of at least one remote station (102).
La détection de mouvement par stéréoscopie ou par stéréovidéo, ainsi que son calibrage, sont réalisés de manière connue par l'homme du métier au moyen d'au moins deux boîtiers (1) sur lesquels sont connectés respectivement au moins une caméra.  The motion detection by stereoscopy or stereovideo, as well as its calibration, are carried out in a manner known to those skilled in the art by means of at least two housings (1) to which at least one camera is respectively connected.
On rappellera ci-après l'ensemble des avantages et des fonctions du système suivant l'invention, lesdites fonctions étant procurées par des algorithmes exécutés par l'unité centrale de traitement d'un ou plusieurs boîtiers (1) et/ou par un ou plusieurs postes distant (102). Levée de doute par photo The advantages and functions of the system according to the invention will be recalled below, said functions being provided by algorithms executed by the central processing unit of one or more housings (1) and / or by one or more several remote stations (102).

Chien de garde Watch dog
De manière avantageuse, le système pourra comporter au moins un système de chien de garde. On entend par « chien de garde », également désigné sous l'anglicisme « watchdog », un logiciel utilisé pour s'assurer qu'un ordinateur ne reste pas bloqué à une étape particulière du traitement qu'il effectue. C'est une protection destinée généralement à redémarrer le système, si une action définie n'est pas exécutée dans un délai imparti. Il s'agit en général d'un compteur qui est régulièrement remis à zéro. Si le compteur dépasse une valeur donnée (timeout) alors on procède à un reset (redémarrage) du système. Le chien de garde consiste souvent en un registre qui est mis à jour via une interruption régulière. Il peut également consister en une routine d'interruption qui doit effectuer certaines tâches de maintenance avant de redonner la main au programme principal. Si une routine entre dans une boucle infinie, le compteur du chien de garde ne sera plus remis à zéro et un reset est ordonné. Le chien de garde permet aussi d'effectuer un redémarrage si aucune instruction n'est prévue à cet effet. Il suffit alors d'écrire une valeur dépassant la capacité du compteur directement dans le registre : le chien de garde lancera le reset. Advantageously, the system may include at least one watchdog system. The term "watch dog", also referred to as "watchdog", is a software used to ensure that a computer does not remain stuck at a particular stage of the processing it performs. It is a protection usually intended to restart the system, if a defined action is not executed within a given time. This is usually a counter that is regularly reset. If the counter exceeds a given value (timeout) then we perform a reset (reboot) of the system. The watchdog often consists of a register that is updated via a regular interruption. It can also consist of an interrupt routine that must perform some maintenance tasks before handing over the main program. If a routine enters an infinite loop, the watchdog counter will no longer be reset and a reset is ordered. The watchdog also allows a restart if no instructions are provided for this purpose. It is then sufficient to write a value exceeding the capacity of the counter directly in the register: the watchdog will initiate the reset.
