Description
Muret anti-intrusion et son application dans des barrières infrarouge LaAnti-intrusion wall and its application in infrared barriers La
présente invention concerne le domaine de la protection contre present invention relates to the field of protection against
l'intrusion d'un périmètre par une barrière de faisceaux infrarouges. the intrusion of a perimeter by a barrier of infrared beams.
De telles barrières sont bien connues en elles mêmes. Elles se composent d'éléments verticaux ou colonnes IR 20 disposées autour du périmètre et contenant les émetteurs e de faisceaux IR régulièrement espacés verticalement, auxquels font face les récepteurs Such barriers are well known in themselves. They consist of vertical elements or IR columns 20 arranged around the perimeter and containing the emitters and IR beams regularly spaced vertically, to which the receivers face
r de la colonne suivante du périmètre. r of the next column of the perimeter.
Les émetteurs et les récepteurs, ainsi que les colonnes, sont disposés de telle manière qu'un intrus ne puisse franchir la limite du périmètre sans "couper" au moins un faisceau. Pour le récepteur correspondant, le faisceau est occulté, et cette occultation déclenche The transmitters and receivers, as well as the columns, are arranged in such a way that an intruder cannot cross the limit of the perimeter without "cutting" at least one beam. For the corresponding receiver, the beam is obscured, and this occultation triggers
une alarme.an alarm.
Il existe naturellement des systèmes connus, plus ou moins sophistiqués, permettant d'éviter au maximum les alarmes intempestives résultant du passage des petits animaux, par exemple. Cependant, ces systèmes atteignent rapidement leurs limites dans certaines configurations, en termes de coût ou de complexité notamment. C'est le cas en particulier en ce qui concerne la coupure possible du dernier There are naturally known systems, more or less sophisticated, making it possible to avoid nuisance alarms as much as possible resulting from the passage of small animals, for example. However, these systems quickly reach their limits in certain configurations, in terms of cost or complexity in particular. This is particularly the case with regard to the possible breaking of the last
faisceau inférieur.lower beam.
Ce dernier faisceau inférieur est nécessairement placé très près This last lower beam is necessarily placed very close
du sol, à environ 20 cm, pour éviter un franchissement par reptation. from the ground, about 20 cm, to avoid crossing by crawling.
Cette faible distance rend inévitables les perturbations intempestives du faisceau par de petits animaux, tels que chats, lapins ou analogues. En effet ces animaux sont suffisamment gros pour déclencher une alarme This small distance inevitably causes untimely disturbance of the beam by small animals, such as cats, rabbits or the like. Indeed these animals are big enough to trigger an alarm
même sur les installations sophistiquées. even on sophisticated installations.
Par ailleurs, la végétation au sol risque de perturber également ce faisceau bas. La solution évidente, qui consiste à traiter ou nettoyer le sol de part et d'autre de la barrière, ne peut être mise en oeuvre facilement, en raison de son coût et des servitudes qu'elle impose, dont celle de neutraliser la barrière durant l'opération, ce qui est délicat s'agissant de sites sensibles tels que installations militaires, In addition, the vegetation on the ground may also disturb this low beam. The obvious solution, which consists in treating or cleaning the ground on either side of the barrier, cannot be implemented easily, because of its cost and the easements which it imposes, including that of neutralizing the barrier during the operation, which is delicate in the case of sensitive sites such as military installations,
industrielles, etc...industrial, etc ...
Il n'existe pas actuellement de solution simple permettant de remédier à ces deux types de problèmes, qui résultent d'une seule There is currently no simple solution to remedy these two types of problems, which result from a single
cause, qui est la coupure intempestive du dernier faisceau IR inférieur. cause, which is the untimely cutting of the last lower IR beam.
Selon l'invention, on dispose un obstacle vertical au niveau du sol de manière à sensiblement remplacer le faisceau inférieur. Cet obstacle est disposé depuis le sol jusqu'à une hauteur se situant sous le second faisceau initial; il a pour fonction de s'opposer au franchissement par reptation, et doit également être suffisamment haut pour dissuader les petits animaux de le franchir par le dessus. Une hauteur appropriée se situe autour de 40 cm. Simultanément, il est avantageux de munir cet obstacle d'une base destinée à reposer sur le sol, pour assurer la stabilité de l'ensemble. Si la base est suffisamment large, par exemple de l'ordre de 30 cm de part et d'autre de l'obstacle vertical, cette base va s'opposer efficacement à l'envahissement par la végétation et va donc contribuer à la solution du problème posé. Outre le fait qu'elle réduira les perturbations du système par la végétation, elle permettra le nettoyage ou le traitement du sol, de part et d'autre de la base, sans qu'il soit According to the invention, there is a vertical obstacle at ground level so as to substantially replace the lower beam. This obstacle is arranged from the ground to a height situated under the second initial beam; its function is to oppose crossing by crawling, and must also be high enough to dissuade small animals from crossing it from above. An appropriate height is around 40 cm. Simultaneously, it is advantageous to provide this obstacle with a base intended to rest on the ground, to ensure the stability of the assembly. If the base is wide enough, for example of the order of 30 cm on either side of the vertical obstacle, this base will effectively oppose the invasion by vegetation and will therefore contribute to the solution of the problem. Besides the fact that it will reduce the disturbances of the system by the vegetation, it will allow the cleaning or the treatment of the soil, on both sides of the base, without it being
nécessaire de neutraliser la barrière. necessary to neutralize the barrier.
Selon un mode préféré de réalisation de l'invention, on dispose des éléments modulaires tels que représentés sur la figure unique According to a preferred embodiment of the invention, there are modular elements as shown in the single figure
annexée, formant un muret après assemblage. attached, forming a low wall after assembly.
La barrière est constituée de manière générale par des colonnes verticales comportant sur leurs côtés en regard des émetteurs IR e et des récepteurs IR r, de manière connue, ainsi que des boîtiers de service 21. L'ensemble délimite un faisceau protecteur de section The barrier generally consists of vertical columns comprising on their sides facing IR emitters and IR r receivers, in a known manner, as well as service boxes 21. The whole delimits a protective beam of section
sensiblement représentée en 22.substantially represented at 22.
Chaque élément 1 selon l'invention se compose d'un élément vertical 3 et d'une base 2. Des ouvertures 4 sont prévues dans les Each element 1 according to the invention consists of a vertical element 3 and a base 2. Openings 4 are provided in the
éléments verticaux 3 pour permettre le libre passage des petits animaux. vertical elements 3 to allow the free passage of small animals.
Il a été établi qu'une ouverture de l'ordre de 10 à 15 cm permet aux animaux de circuler sans être tentés par un franchissement par le dessus. Sur le sommet de l'élément vertical 3, on place une herse 5 ou un ensemble de pointes destinées à empêcher les oiseaux de se poser sur le système. Ces pointes peuvent aussi être orientées selon plusieurs directions pour une meilleure efficacité. Le faisceau immédiatement supérieur 7 est naturellement suffisamment proche pour empêcher toute reptation. Les éléments s'assemblent de préférence à l'aide It has been established that an opening of the order of 10 to 15 cm allows animals to circulate without being tempted by a crossing from above. On the top of the vertical element 3, a harrow 5 or a set of spikes is placed intended to prevent birds from landing on the system. These tips can also be oriented in several directions for better efficiency. The immediately upper beam 7 is naturally close enough to prevent crawling. The elements are preferably assembled using
d'entretoises 8, avantageusement en acier inoxydable. spacers 8, advantageously made of stainless steel.
De manière avantageuse, les entretoises 8 sont prolongées dans la masse des éléments, et au moins au niveau des obstacles verticaux, mais de préférence aussi bien dans les éléments verticaux que dans la base, par des gaines plastiques 9 pour le passage de câbles 6. Il s'agira notamment des câbles d'alimentation électrique des colonnes. Ceci représente un autre avantage important de l'invention car les câbles sont Advantageously, the spacers 8 are extended in the mass of the elements, and at least at the level of the vertical obstacles, but preferably both in the vertical elements and in the base, by plastic sheaths 9 for the passage of cables 6. These will include the power cables for the columns. This represents another important advantage of the invention because the cables are
à la fois invisibles et protégés, et on peut se dispenser de gaines etc.. . both invisible and protected, and you can dispense with sleeves, etc.
annexes. On utilisera également ces passages 8, 9 pour former des boucles d'autoprotection, c.a.d. déclenchant une alarme en cas de détérioration (par exemple lors d'une tentative de détérioration du muret). annexes. These passages 8, 9 will also be used to form self-protection loops, ie triggering an alarm in the event of deterioration (for example when an attempt is made to deteriorate the wall).
L'invention n'est pas limitée à l'exemple donné ci-dessus. The invention is not limited to the example given above.
L'invention couvre au contraire également tous les modes de réalisation, adaptations diverses et variantes qui seront directement accessibles à The invention, on the contrary, also covers all the embodiments, various adaptations and variants which will be directly accessible to
l'homme du métier à la lecture du principe général et de l'exemple ci- a person skilled in the art on reading the general principle and the example above
dessus. Ainsi, le muret peut être remplacé par un grillage ou grille ou analogue, comportant des ouvertures 4. La herse peut être remplacée par tout système visant à dissuader les oiseaux de se poser sur le sommet du muret ou de la grille ou grillage ou analogue, comme par exemple un fil électrifié. On peut aussi utiliser sur le haut du muret un double fil électrifié, disposé de telle sorte que l'oiseau ou autre animal établit le contact en se posant ou en prenant appui sur le muret, ce qui déclenche la secousse électrique. On pourra aussi remplacer les deux premiers faisceau inférieurs, et dispositions analogues, selon par exemple la configuration du terrain. Quant aux ouvertures 4, elles above. Thus, the low wall can be replaced by a grid or grate or the like, comprising openings 4. The harrow can be replaced by any system intended to dissuade the birds from landing on the top of the low wall or the grid or grate or the like, like for example an electrified wire. You can also use a double electrified wire on the top of the wall, arranged so that the bird or other animal makes contact by landing or leaning on the wall, which triggers the electric shock. We can also replace the first two lower beams, and similar arrangements, for example according to the configuration of the terrain. As for the openings 4, they
peuvent être placées au sol et/ou proches du sol. can be placed on the ground and / or close to the ground.
L'invention s'applique à tout type de barrière anti-intrusion pour laquelle se pose le même problème. The invention applies to any type of anti-intrusion barrier for which the same problem arises.
