Description

La sécurité ou la prévention nécessite la surveillance des lieux où peuvent survenir des événements qui peuvent être dramatiques, surveillance des risques d'incendie, surveillance des actes de vol ou de déprédation dans les lieux publics ou privés, surveillance des activités qui peuvent engen- drer des accidents dans les usines, les chantiers ou sur les routes.Security or prevention requires surveillance of places where events that may be dramatic can occur, surveillance of fire risks, surveillance of acts of theft or depredation in public or private places, surveillance of activities that may generate r er accidents in factories, construction sites or on the road.

Les moyens de surveillance actuellement connus peuvent être des détecteurs qui sont en liaison avec des organes de visualisation des signaux qu'ils 'émettent ou des organes sonores qui alertent le personnel qui est chargé d'intervenir en pareille circonstance, ou qui sont directement reliés au dispositif de protection mettant automatiquement en oeuvre le dispositif de défense, tel qu' une émission d'eau ou d'autre produit permettant de lutter' contre l'incendie, ou une émission de gaz incommodant s'opposant à l' action des délinquants.The currently known monitoring means can be detectors which are in connection with organs for displaying the signals which they emit or audible organs which alert the personnel responsible for intervening in such circumstances, or which are directly connected to the protection device that automatically implements the defense device, such as a water or other fire-fighting product, or an annoying gas emission opposing the action of the offenders.

Ces détecteurs sont du type thermique, agissant sous l'influence de la température, du type électronique agissant sous l'influence des rayonnements infrarouges, des ondes ultra-sonores ou d'une émission hyperfréquence sensible aux déplacements volumétriques. Ils sont parfois accompagnés d'une possibilité de vision instantanée du lieu mis sous surveillance, au moyen d'une caméra, ou micro-caméra vidéo reliée à un écran moniteur.These detectors are of the thermal type, acting under the influence of temperature, of the electronic type acting under the influence of infrared radiation, ultrasonic waves or of a microwave emission sensitive to volumetric displacements. They are sometimes accompanied by a possibility of instant vision of the place under surveillance, by means of a video camera or micro-camera connected to a monitor screen.

Quelle que soit l'étendue du champ d'efficacité de chacun de ces dispositifs, quel que soit donc leur angle de surveillance, la surface ou le volume de leur efficacité est toujours limité. Même lorsqu'il a été prévu de les rendre mobiles sur un axe afin qu'ils puissent accroître leur rayonnement par une rotation angulaire alternative.Whatever the extent of the field of effectiveness of each of these devices, whatever their angle of surveillance, the surface or the volume of their effectiveness is always limited. Even when it has been planned to make them mobile on an axis so that they can increase their radiation by an alternative angular rotation.

L'efficacité de tels dispositifs ne peut donc être accrue en surface que par leur multiplication, ce qui rend le procédé onéreux quel que soit le dispositif choisi.The efficiency of such devices can therefore only be increased at the surface by their multiplication, which makes the process expensive regardless of the device chosen.

L'objet de la présente invention a donc pour but d'accroître. de façon pratiquement illimitée, le champ d'observation d'un même organe détecteur ou de visualisation.The object of the present invention therefore aims to increase. practically unlimited, the field of observation of the same detector or display member.

Pour cela, l'organe détecteur ou visualisateur est rendu mobile non plus par un mouvement rotatif dans le plan horizontal mais par une translation parallèle à son axe sur des distances qui' ne sont par les limites mêmes de l'espace à surveiller, quelle que soit sa longueur. L'organe de surveillance étant, par exemple une caméra-vidéo, celle-ci sera propulsée par des moyens divers à l'intérieur d'un tube, dont une partie au moins de la paroi est transparente selon une génératrice afin de permet tre une observation constante par la caméra sur la totalité de son parcours à l'intérieur du tube qui suit tous les contours nécessaires pour suivre le trajet sur lequel la surveillance doit s'exercer.For this, the detector or viewer is made mobile no longer by a rotary movement in the horizontal plane but by a translation parallel to its axis over distances which are not by the very limits of the space to be monitored, whatever its length. The monitoring device being, for example a video camera, it will be propelled by various means inside a tube, at least part of the wall of which is transparent according to a generator in order to allow a constant observation by the camera over its entire path inside the tube which follows all the contours necessary to follow the path on which surveillance must be exercised.

Un tel dispositif peut donc être utilisé de façon avantageuse pour la surveillance de locaux de grandes dimensions et peut même aller jusqu'à être utilisé pour la surveillance des circuits routiers, surveillance qui peut s'exercer pour connaître l'état de la chaussée, la densité de la circulation, le comportement individuel des conducteurs, les lieux et même parfois les circonstances d'un accident, ou celles qui y ont conduit.Such a device can therefore be used advantageously for monitoring large premises and can even go so far as to be used for monitoring road circuits, monitoring which can be carried out to ascertain the condition of the roadway, the traffic density, individual driver behavior, places and sometimes even the circumstances of an accident, or those which led to it.

Tel qu'il est représenté, le tube conducteur 1 est constitué par un tube cylindrique ou polygonal étanche, en matériau rigide, muni au moins d'un côté, sur une certaine surface, parallèle aux génératrices du cylindre, d'une paroi 2 parfaitement transparente constituée d'une surface plane à face parallèle afin de ne créer aucune déformation optique, la liaison de ladite paroi transparente 'avec le tube étant parfaitement étanche sur toute sa longueur.As shown, the conductive tube 1 consists of a tight cylindrical or polygonal tube, of rigid material, provided at least on one side, on a certain surface, parallel to the generatrices of the cylinder, with a wall 2 perfectly transparent consisting of a flat surface with a parallel face so as not to create any optical deformation, the connection of said transparent wall 'with the tube being perfectly sealed over its entire length.

Intérieurement, le tube conducteur 1 est muni, à chaque'extrémité du diamètre orthogonal au plan diamétral qui contient la ou les surfaces transparentes longitudinales, et à chacune des extrémités de ce diamètre, des rails 3 et 4 prismatiques solidaires de la paroi intérieure,

Figure imgb0001
étant faits d'une matière isolante électriquement identique à celle constituant le tube ou différente.Internally, the conductive tube 1 is provided, at each end of the diameter orthogonal to the diametral plane which contains the longitudinal transparent surface (s), and at each of the ends of this diameter, rails 3 and 4 prismatic integral with the interior wall,
Figure imgb0001
being made of an electrically insulating material identical to that constituting the tube or different.

' Les rails prismatiques 3 et 4 qui parcourent les génératrices internes diamétralement opposées du tube 1 sur toute sa longueur comportent sur une ou plusieurs de leurs faces, solidaire d'elles, des bandes métalliques 16 en nombre suffisant pour transmettre les multiples signaux électriques qui assureront la conduite et la manipulation de la caméra qui parcourra le tube conducteur ainsi organisé et éventuellement d'autres fonctions. ' The prismatic rails 3 and 4 which run through the diametrically opposite internal generators of the tube 1 over its entire length have on one or more of their faces, integral with them, metal bands 16 in sufficient number to transmit the multiple electrical signals which will ensure driving and manipulating the camera which will run through the conductive tube thus organized and possibly other functions.

Extérieurement aux limites supérieure et inférieure de la surface transparente 2 est installé un tube 5 portant de multiples perforations 6 fines et suffisamment rapprochées pour que chacun des jets de liquide sous pression qui s'échappera desdites perforations sous forme de pulvériation couvre une surface qui recoupe la surface atteinte par la perforation voisine afin que la totalité de la surface de la fenêtre 2 se trouve atteinte par les jets émanant desdites perforations 6.Externally at the upper and lower limits of the transparent surface 2 is installed a tube 5 carrying multiple fine perforations 6 and sufficiently close together so that each of the jets of liquid under pressure which will escape from said perforations in the form of spraying covers a surface which intersects the surface reached by the adjacent perforation so that the entire surface of the window 2 is reached by the jets emanating from said perforations 6.

Le nettoyage de ladite surface transparente 2 peut aussi être obtenu au moyen d'une brosse extérieure montée sur un support magnétique et entraînée par l'obus 8 au moyen d'un aimant solidaire de l'obus 8 et développant un champ magnétique de forte intensité et se déplaçant à l'intérieur du tube.The cleaning of said transparent surface 2 can also be obtained by means of an external brush mounted on a magnetic support and driven by the shell 8 by means of a magnet secured to the shell 8 and developing a strong magnetic field. and moving inside the tube.

L'objet utilisé pour la surveillance qui circule à l'intérieur du tube conducteur 1 est la micro-caméra 7 fixée à l'intérieur de l'obus 8 dont les deux extrémités avant et arrière 9 et 10 sont constituées par un disque en matière plastique auto-lubrifiante, telle que le polytétrafluoé- thylène, qui parcourent la paroi intérieure du cylindre 1 à frottement doux de façon à assurer à ce niveau une étanchéité suffisante.The object used for surveillance which circulates inside the conductive tube 1 is the micro-camera 7 fixed inside the shell 8, the two front and rear ends 9 and 10 of which are constituted by a disc made of material. self-lubricating plastic, such as polytetrafluoroethylene, which run through the interior wall of the cylinder 1 with gentle friction so as to ensure at this level a sufficient seal.

L'objectif 12 de la micro-caméra 7 est orienté vers l'arrière de l'obus 8, son axe optique étant parallèle à l'axe du tube conducteur 1. La micro-caméra 7 est du type sensible au rayonnement infra-rouge de manière à permettre l'observation nocturne.The objective 12 of the micro-camera 7 is oriented towards the rear of the shell 8, its optical axis being parallel to the axis of the conductive tube 1. The micro-camera 7 is of the type sensitive to infrared radiation so as to allow night observation.

En arrière dudit objectif est placé un dièdre réfléchissant 11 dont l'arête est verticale dans le plan de l'axe de l'optique 12 de la micro-caméra et coupe ledit axe, et dont les miroirs plans, qui forment ledit dièdre ouvert vers l'arrière de !'obus, permettent à l'objectif de la caméra de recevoir alternativement ou simultanément les images provenant de la ou de chacune des surfaces transparentes longitudinales 2 du tube 1 à l'intérieur duquel la micro-caméra peut circuler étant guidée par les rails 3 et 4.Behind said objective is placed a reflecting dihedral 11 whose edge is vertical in the plane of the axis of the optics 12 of the micro-camera and cuts said axis, and whose plane mirrors, which form said dihedral open towards the rear of the shell, allow the lens of the camera to receive alternately or simultaneously the images originating from or from each of the transparent longitudinal surfaces 2 of the tube 1 inside which the micro-camera can circulate being guided by rails 3 and 4.

Ce guidage de la caméra, tout le long de son parcours à l'intérieur du tube 1, est obtenu par les évidements 13 et 14 (fig. 3a et 3b) qui sont aménagés à cet effet à la périphérie de chacun des disques auto-lubrifiants 9 et 10 qui supportent l'obus 8 qui contient la caméra 7 et que traversent réciproquement les rails 3 et 4.This guidance of the camera, all along its path inside the tube 1, is obtained by the recesses 13 and 14 (fig. 3a and 3b) which are arranged for this purpose at the periphery of each of the self-supporting discs. lubricants 9 and 10 which support the shell 8 which contains the camera 7 and which reciprocally cross the rails 3 and 4.

Les contacts métalliques élastiques 15, en nombre suffisant, sont situés dans chacun des évidements 13 et 14 et sont organisés pour rester constamment au contact des bandes conductrices 16, lesdits contacts transmettant aux organes intéressés à l'intérieur ou à l'extérieur de la caméra 7 les impulsions électriques nécessaires pour assurer à la caméra 7 toutes ses fonctions internes ainsi que toutes les fonctions extérieures nécessaires au bon fonctionnement de l'ensemble et à la transmission instantanée des images ou autres signaux ainsi créés.The elastic metal contacts 15, in sufficient number, are located in each of the recesses 13 and 14 and are organized to remain constantly in contact with the conductive strips 16, said contacts transmitting to the bodies concerned inside or outside the camera. 7 the electrical pulses necessary to ensure the camera 7 all its internal functions as well as all the external functions necessary for the proper functioning of the assembly and for the instantaneous transmission of the images or other signals thus created.

Les disques d'extrémités 9 et 10 sont aussi munis, au niveau de la ou des surfaces transparentes 2 du tube 1 d'un tampon auto-nettoyant 17 qui reste constamment au contact de la surface interne de la ou des fenêtres 2 du tube conducteur.The end discs 9 and 10 are also provided, at the transparent surface or surfaces 2 of the tube 1 with a self-cleaning pad 17 which remains constantly in contact with the internal surface of the window (s) 2 of the conductive tube .

Enfin les crochets 18 situés extérieurement de part et d'autre de l'obus-caméra 8 permettent l'accrochage de un ou plusieurs obus en vue de leur déplacement simultané.Finally the hooks 18 located externally on either side of the camera shell 8 allow the attachment of one or more shells for their simultaneous movement.

Le dispositif étant ainsi constitué, l'obus-caméra 8 pourra parcou-' rir intérieurement le tube dans la totalité de sa longueur, dans ses parties rectilignes ou courbes, celles-ci présentant un rayon de courbure compatible avec la, longueur de l'obus 8.The device thus being constituted, the shell-camera 8 will be able to run through the tube internally over its entire length, in its rectilinear or curved parts, these having a radius of curvature compatible with the length of the shell 8.

L'élément moteur peut être un gaz comprimé sec et filtré, tel que l'air, l'arrière 10 de l'obus 8 étant soumis à la pression du gaz mis en mouvement par tout système compresseur, et son avant 9 étant inversement soumis à une dépression créée en amont de la tuyauterie, le gaz utilisé étant mis en pression ou en dépression par tout moyen connu, et la pression d'air éventuellement utilisée pouvant être la pression atmosphérique.The driving element can be a dry and filtered compressed gas, such as air, the rear 10 of the shell 8 being subjected to the pressure of the gas set in motion by any compressor system, and its front 9 being inversely subjected a vacuum created upstream of the piping, the gas used being pressurized or vacuumed by any known means, and the air pressure possibly used can be atmospheric pressure.

La proputsion de l'obus 8 peut aussi être obtenue par voie magnétique, ou au moyen d'un moteur linéaire dont l'inducteur est organisé à l'intérieur de l'un ou des deux rails 3 et 4.The propulsion of the shell 8 can also be obtained by magnetic means, or by means of a linear motor whose inductor is organized inside one or both rails 3 and 4.

Sur de courtes distances, la propulsion de l'obus 8 peut être obtenue par compression d'un fluide liquide. Dans ce cas la progression est plus lente, mais l'étanchéité au niveau des disques 8 et 9 est meilleure, ce qui assure un meilleur rendement énergétique.Over short distances, the propulsion of the shell 8 can be obtained by compression of a liquid fluid. In this case, the progression is slower, but the tightness at the level of the discs 8 and 9 is better, which ensures better energy efficiency.

Sur de plus courtes distances encore la progression de l'obus 8 peut être assuré par le jeu de 2 filins souples manoeuvrés par des treuils situés aux extrémités du tube 1 et qui, étant arimés aux crochets 18 de l'engin, permettent de le déplacer alternativement dans les deux sens.Over even shorter distances the progression of the shell 8 can be ensured by the game of 2 flexible ropes maneuvered by winches located at the ends of the tube 1 and which, being stowed on the hooks 18 of the machine, allow it to be moved alternately in both directions.

Même dans certains cas le déplacement de l'obus 8 peut être assuré par la rotation d'une vis-mère longitudinale mise en rotation à l'intérieur du tube 1 et qui traverse successivement les disques 9 et 10 à l'intérieur desquels sont situés les écrous correspondants, la progression, dans ce cas, étant obtenue par la rotation de ladite vis-mère.Even in some cases the displacement of the shell 8 can be ensured by the rotation of a longitudinal mother screw rotated inside the tube 1 and which successively crosses the discs 9 and 10 inside which are located the corresponding nuts, the progression, in this case, being obtained by the rotation of said lead screw.

Un moteur, qui reçoit les impulsions électriques de commande par l'intermédiaire aussi des bandes métalliques 16, permet de commander l'orientation des faces réfléchissantes du dièdre 11, de manière que l'objectif 12, dont l'axe est parallèle à l'axe du tube 1, reçoive les images d'un champ orthogonal à l'axe de l'appareil, ce qui permet à l'objectif 12 de recevoir alternativement ou simultanément les images observées de part et d'autre du tube 1, à travers la ou les bandes transparentes 2 diamétralement opposées dans le plan horizontal.A motor, which receives the electrical control pulses also by means of the metal strips 16, makes it possible to control the orientation of the reflecting faces of the dihedral 11, so that the objective 12, whose axis is parallel to the axis of the tube 1, receives the images of a field orthogonal to the axis of the camera, which allows the lens 12 to receive alternately or simultaneously the images observed on either side of the tube 1, through the transparent strip (s) 2 diametrically opposite in the horizontal plane.

La transmission des images ainsi reçues par la caméra peut être effectuée par faisceau hertzien, au moyen de l'ensemble électronique 19 contenu dans l'un des disques 9 ou 10 (fig. 3). Le message ainsi adressé soit par voie hertzienne, soit à travers les bandes métalliques 16, est un message vidéo UHF reçu par les écrans-moniteurs du poste central d'observation ou un message directement numérique reçu par ses ordinateurs, ou un message vidéo, numérisé par un convertisseur intermédiaire.The images thus received by the camera can be transmitted by radio beam, by means of the electronic assembly 19 contained in one of the disks 9 or 10 (fig. 3). The message thus addressed either by radio or through the metal strips 16, is a UHF video message received by the monitor screens of the central observation post or a directly digital message received by its computers, or a digital video message by an intermediate converter.

Sur de courtes distances, sur lesquelles le tube 1 peut être parfaitement rectiligne, la transmission des signaux peut être effectuée par rayon laser émis par un dispositif contenu simultanément dans l'obus 8.Over short distances, over which the tube 1 can be perfectly straight, the signals can be transmitted by laser beam emitted by a device simultaneously contained in the shell 8.

L'utilisation des signaux binaires pour la transmission des messages est avantageuse car elle permet la comparaison immédiate de l'image reçue avec une image-type contenue dans la mémoire de l'ordinateur et par ce moyen l'émission immédiate d'un-ordre qui est la conséquence des différences ou des coïncidences observées entre l'image reçue et l'image mémorisée.The use of binary signals for the transmission of messages is advantageous because it allows the immediate comparison of the received image with a standard image contained in the computer memory and by this means the immediate issuance of an order. which is the consequence of the differences or coincidences observed between the received image and the memorized image.

C'est ainsi qu'une prévention très utile peut être assurée sur le réseau routier.This is how very useful prevention can be ensured on the road network.

Si, en effet, les images d'une route chargée de brouillard, ou d'une route mouillée, ou encore d'une route enneigée sont contenues dans la mémoire de l'ordinateur central, il sera facile, si une caméra parcourt un tube 1 placé tout le long des bas-côtés d'une autoroute de comparer les images binaires reçues aux images mémorisées, l'ordinateur réagissant aussitôt pour envoyer les ordres de prévention nécessaires dès qu'une coïncidence sera constatée entre les deux images superposées.If, in fact, the images of a road loaded with fog, or of a wet road, or even of a snow-covered road are contained in the memory of the central computer, it will be easy, if a camera traverses a tube 1 placed all along the aisles of a highway to compare the binary images received with the stored images, the computer reacting immediately to send the necessary prevention orders as soon as a coincidence is observed between the two superimposed images.

Le tube 1 comporte alors avantageusement, à des distances périodiques connues des spots émetteurs de signaux codés reçus par la caméra lors de son passage en chacun de ces points et qui permettent à l'ordinateur central et à un moniteur de visualisation de situer de façon précise l'emplacement de la caméra lors de l'émission d'une image déterminée, et même de la suivre sur ledit écran.The tube 1 then advantageously comprises, at known periodic distances from the spots emitting coded signals received by the camera during its passage at each of these points and which allow the central computer and a display monitor to locate precisely the location of the camera during the emission of a determined image, and even to follow it on said screen.

En cas de besoin, l'obus 8 peut être immobilisé en un point quelconque du circuit qu'il parcourt dès qu'un événement est constaté au poste central de contrôle, par la simple interruption du débit d'air, afin de permettre la visualisation permanente de la poursuite de l'événement (accident par exemple et ses suites).If necessary, the shell 8 can be immobilized at any point on the circuit which it traverses as soon as an event is observed at the central control station, by the simple interruption of the air flow, in order to allow viewing permanent continuation of the event (accident for example and its aftermath).

Les tubes externes 5 munis des perforations 6 sont utilisés pour pulvériser du liquide nettoyant sur la face externe de la paroi transparente 2.The external tubes 5 provided with the perforations 6 are used to spray cleaning liquid on the external face of the transparent wall 2.

Dans le cas d'utilisation du dispositif pour la surveillance sur de grandes distances, sur des autoroutes par exemple, sur lesquelles le tube 1 sera placé sur chacun de ses rails latéraux existants, lorsqu'il est muni d'une seule surface transparente, ou sur le rail central s'il est muni de deux surfaces transparentes diamétralement opposées, l'ensemble est organisé à la manière des transports pneumatiques connus, c'est à dire qu'il peut comporter des systèmes d'aiguillage permettant de dévier l'obus 8 vers une autre voie, soit pour l'orienter dans une autre direction, soit pour l'immobiliser temporairement hors du circuit principal selon les besoins du moment.In the case of using the device for surveillance over long distances, on motorways for example, on which the tube 1 will be placed on each of its existing side rails, when it is provided with a single transparent surface, or on the central rail if it is provided with two diametrically opposite transparent surfaces, the assembly is organized in the manner of transport known tires, that is to say that it may include referral systems making it possible to divert the shell 8 towards another track, either to orient it in another direction, or to immobilize it temporarily outside the main circuit according to the needs of the moment.

Le réseau tubulaire conducteur ainsi constitué peut aussi comporter des systèmes d'électrovannes distribuées sur son parcours et qui commandées par des impulsions codées transmises à travers les lames conductrices 16 permettent de contrôler la vitesse de déplacement de la micro-caméra, et éventuellement son arrêt dans une section déterminée.The conductive tubular network thus formed may also include solenoid valve systems distributed along its path and which controlled by coded pulses transmitted through the conductive strips 16 make it possible to control the speed of movement of the micro-camera, and possibly its stopping in a specific section.

La présence d'électrovannes en des points espacés du tube conducteur 1 permet de disposer si nécessaire, en ces. différents points, du fluide commprimé contenu dans le tube lors de son fonctionnement. Cela permet de procéder, si nécessaire, au gonflage rapide d'une structure gonflable telle qu'un cylindre de plastique souple luminescent, qui peut ainsi se dresser afin de constituer une balise d'alerte au point le plus proche d'un accident par exemple.The presence of solenoid valves at points spaced from the conductive tube 1 makes it possible to have these, if necessary. different points, of the compressed fluid contained in the tube during its operation. This makes it possible, if necessary, to rapidly inflate an inflatable structure such as a luminescent flexible plastic cylinder, which can thus stand up to constitute an alert beacon at the point closest to an accident for example .

De même des relais réagissant au passage de la micro-caméra en déplacement permettent de la localiser, l'impulsion codée qu'ils émettent étant reçue au poste central de contrôle à travers les mêmes lames 16.Similarly, relays reacting to the passage of the moving micro-camera make it possible to locate it, the coded pulse which they emit being received at the central control station through the same blades 16.

L'invention n'est pas limitée à l'exemple ou aux exemples qui en ont été décrits, toute variante, considérée comme une équivalence, ne pouvant en modifier la portée.The invention is not limited to the example or examples which have been described, any variant, considered as an equivalence, which cannot modify its scope.

C'est ainsi que dans certains cas, les signaux émis par la caméra peuvent être transmis par rayonnement infrarouge, ou par vibrations ultra-sonores.Thus, in some cases, the signals emitted by the camera can be transmitted by infrared radiation, or by ultrasonic vibrations.

L'invention peut être utilisée en tout lieu où la surveillance ou la prévention doivent être exercées sur des distances difficilement couvertes par une caméra stationnaire, même munie d'un objecti grand angle, le moyen de propulsion de la micro-caméra à l'intérieur du tube conducteur étant adapté aux impératifs d'installation et en particulier aux distances de déplacement nécessaires.The invention can be used in any place where surveillance or prevention must be exercised over distances difficult to cover by a stationary camera, even with a wide-angle object, the means of propulsion of the micro-camera inside of the conductive tube being adapted to installation requirements and in particular to the necessary travel distances.

C'est ainsi que dans les lieux publics de grande surface les réseaux peuvent n'être installés que sous le forme rectiligne qui permet la propulsion par cable ou par vis-mère rotative. Si de tels réseaux comportent des courbes, la propulsion peut être organisée au moyen d'un fluide qui est comprimé en aval et mis en dépression en amont, la vitesse de déplacement ainsi obtenue dépendant de la densité et de la viscosité dudit fluide, la plus grande vitesse étant obtenue au moyen d'un fluide gazeux, l'al par exemple, ce dernier devant généralement être employé dans les réseaux à grande distance, pour la surveillance du réseau routier par exemple.Thus in public places of large surface networks can be installed only in the rectilinear form which allows the propulsion by cable or by rotary mother screw. If such networks include curves, the propulsion can be organized by means of a fluid which is compressed downstream and placed under vacuum upstream, the speed of movement thus obtained depending on the density and viscosity of said fluid, the more high speed being obtained by means of a gaseous fluid, al for example, the latter generally having to be used in long distance networks, for monitoring the road network for example.
