Description
La présente invention concerne un dispositif de guidage d'un engin volant, notamment un missile.The present invention relates to a device for guidance of a flying object, in particular a missile.
Plus précisément, la présente invention concerne un dispositif de guidage nécessitant une intervention humaine, à savoir un dispositif de guidage du type comportant :
- un capteur d'images monté sur ledit engin volant ou agencé au sol et engendrant des images de l'environnement situé à l'avant dudit engin volant ;
- des moyens de transmission de données ;
- un poste de guidage recevant les images engendrées par ledit capteur d'images par l'intermédiaire desdits moyens de transmission de données et permettant à un opérateur de sélectionner sur chaque image un point de guidage vers lequel il désire guider ledit engin volant ; et
- des moyens de calcul qui déterminent des ordres de guidage de l'engin volant, à partir des points de guidage ainsi sélectionnés, lesdits ordres de guidage étant transmis à des organes de guidage montés sur ledit engin volant.
- an image sensor mounted on said flying vehicle or arranged on the ground and generating images of the environment located in front of said flying vehicle;
- data transmission means;
- a guidance station receiving the images generated by said image sensor via said data transmission means and allowing an operator to select on each image a guidance point towards which he wishes to guide said flying machine; and
- calculation means which determine guidance orders for the flying object, from the guide points thus selected, said guidance orders being transmitted to guide members mounted on said flying object.
On sait que pour le guidage d'armes volantes telles que des missiles antichar par exemple, on recherche de plus en plus une intervention humaine, puisque seule une telle intervention permet de gérer efficacement les situations de plus en plus complexes (comme une identification entre des intervenants amis, ennemis et neutres) apparaissant dans les conflits présents et/ou futurs (crise politique, opération de maintien de la paix, ...).We know that for the guidance of flying weapons such that anti-tank missiles for example, we are looking for more and more human intervention, since only one such intervention makes it possible to manage situations effectively more and more complex (as an identification between friendly, enemy and neutral stakeholders) appearing in present and / or future conflicts (crisis political, peacekeeping operation, ...).
Généralement, ledit poste de guidage comprend un pupitre muni d'un écran pour visualiser les images engendrées par ledit capteur d'images et un manche pour commander le déplacement d'un réticule de pointage sur ledit écran. Pour réaliser le guidage de l'engin volant, l'opérateur amène ledit réticule de pointage au point sélectionné sur ladite image, c'est-à-dire au point à atteindre par l'engin volant, par exemple le centre d'une cible.Generally, said guide station includes a desk with a screen for viewing the generated images by said image sensor and a handle for controlling moving a pointing reticle on said screen. To guide the flying machine, the operator brings said aiming reticle to the selected point on said image, i.e. at the point to be reached by the flying object, for example the center of a target.
Toutefois, un tel mode de guidage présente de nombreux inconvénients, et notamment une manipulation délicate et une optimisation difficile et lente.However, such a guidance mode has many disadvantages, including delicate handling and difficult and slow optimization.
En effet, comme l'opérateur trouve souvent difficilement la relation entre l'effort qu'il exerce sur le manche et la vitesse et l'amplitude de déplacement du réticule de pointage sur l'écran, le pointage s'accompagne généralement d'oscillations plus ou moins amorties autour de la position sélectionnée, ce qui entraíne bien entendu un temps de pointage relativement long (d'environ une seconde dans le meilleur des cas) et une précision aléatoire.Indeed, as the operator often finds it difficult the relationship between the effort it exerts on the stick and the speed and range of displacement of the reticle pointing on the screen, the pointing is accompanied generally of more or less damped oscillations around of the selected position, which of course leads a relatively long aiming time (about one second in the best of cases) and random precision.
La présente invention a pour objet de remédier à ces inconvénients. Elle concerne un dispositif de guidage d'un engin volant, notamment un missile, qui permet à un opérateur de réaliser le guidage de façon extrêmement rapide et précise.The object of the present invention is to remedy these disadvantages. It relates to a guiding device a flying object, notably a missile, which allows a operator to carry out the guidance extremely quickly and precise.
A cet effet, selon l'invention, le dispositif de guidage du type précité est remarquable en ce que ledit poste de guidage comprend un écran tactile, sur lequel sont visualisées les images engendrées par ledit capteur d'images, la sélection desdits points de guidage étant réalisée par un contact ponctuel de l'écran tactile aux points considérés, de préférence soit au moyen d'un doigt de l'opérateur, soit à l'aide d'un stylo optique.To this end, according to the invention, the device for guidance of the aforementioned type is remarkable in that said guidance station includes a touch screen, on which the images generated by said sensor are viewed of images, the selection of said guide points being made by a specific contact of the touch screen to points considered, preferably either by means of a finger operator, either using an optical pen.
Ainsi, grâce à l'invention, on obtient notamment les avantages suivants :
- une réduction du temps de pointage, puisque le doigt de l'opérateur ou le stylo optique va directement sur le point choisi, ce qui permet de remédier aux problèmes d'oscillations du pointage existant dans la solution usuelle précitée ; et
- une augmentation de la précision du pointage, notamment lorsqu'on utilise un crayon optique, dont l'extrémité est plus fine que celle d'un doigt.
- a reduction in pointing time, since the operator's finger or the optical pen goes directly to the point chosen, which makes it possible to remedy the problems of pointing oscillations existing in the usual solution mentioned above; and
- an increase in pointing accuracy, especially when using an optical pencil, the end of which is finer than that of a finger.
De plus, il est possible de laisser glisser le doigt ou le crayon optique sur l'écran pour permettre le suivi d'un objectif mobile, en temps réel, ce qui permet notamment de s'affranchir d'une poursuite automatique de la cible par traitement d'images et donc de simplifier énormément les algorithmes des moyens de calcul et ainsi de réduire le coût du guidage.In addition, it is possible to let the finger or the optical pencil on the screen to allow the tracking a mobile goal, in real time, which allows notably to get rid of an automatic pursuit of the target by image processing and therefore to simplify enormously the algorithms of the computing means and so reduce the cost of guidance.
Par ailleurs, de façon avantageuse, la transmission de données entre l'engin volant et le poste de guidage situé au sol est réalisée au moyen d'une liaison hertzienne et/ou d'une liaison à fibre optique.Furthermore, advantageously, the transmission between the flying machine and the guidance station located on the ground is carried out by means of a hertzian connection and / or a fiber optic link.
L'unique figure du dessin annexé fera bien comprendre comment l'invention peut être réalisée. Elle montre schématiquement un dispositif de guidage conforme à l'invention.The single figure in the attached drawing will make it clear how the invention can be realized. She shows schematically a guide device according to the invention.

precise and fast from point P, said
Les moyens de calcul 4 déterminent alors, en continu, des ordres de guidage qui permettent de déplacer le missile M de manière à amener un réticule R situé au centre de l'écran tactile ET, audit point P sélectionné et ainsi à guider le missile M sur la cible C.The calculation means 4 then determine, continuously, guidance orders that move the missile M so as to bring a reticle R located in the center of the touch screen AND, at said selected point P and thus to guide missile M on target C.
Selon l'invention, la transmission de données entre le missile M et le sol peut être réalisée, soit au moyen d'une liaison à fibre optique, telle que la liaison L2, soit au moyen d'une liaison hertzienne, telle que la liaison L1.According to the invention, the transmission of data between the missile M and the ground can be achieved either by means a fiber optic link, such as the L2 link, either by radio link, such as link L1.
De plus, ladite transmission de données peut être
effectuée, soit par des moyens séparés pour les deux sens
