Abstract

The rigid cylinder (6) has a flexible membrane (7) at it's lower end which is used to support a rod (8). The upper end of the rod lies within the cylinder (6) and carries a magnet (5) which is immediately opposite to a Hall effect sensor (4). The lower end of the rod (8) is immersed in the fish breeding tank and bears a lure (9,10). When the lure is touched the rod moves and the magnet (5) operates the Hall effect sensor. A signal is then sent along a cable (1) to a feeding mechanism which distributes food.

Description

Sonde tactile pour l'élevage aquacole
L'invention concerne un dispositif électromécanique qui permet, une fois plongé en pattie dans un bassin d'élevage aquacole, de transformer l'action d'un poisson qui excite cette tige, en un signal électrique utilisable pour déclencher une séquence d'alimentation, ou directement des distributeurs d'aliments
Etat de l'art:
Cette technique de l'autoalimentation a été développée depuis une dizaine d'année, car elle semble donner de meilleurs résultats que l'alimentation classique, manuelle ou programmée à heure fixe.Tactile probe for aquaculture farming
The invention relates to an electromechanical device which makes it possible, once plunged into a part in an aquaculture breeding basin, to transform the action of a fish which excites this rod, into an electrical signal usable for triggering a feeding sequence, or directly from food distributors
State of the art:
This self-feeding technique has been developed for ten years, because it seems to give better results than conventional, manual or programmed feeding at a fixed time.

Les résultats et travaux antérieurs ont principalement porté sur les méthodes et procédés de couplage de ces tiges tactiles à des distributeurs d'aliment, ainsi que sur différents procédés de réalisation de ces tiges tactiles. Entre autres procédés, il existe les systèmes purement mécaniques (de type pendulaire), ou électromécanique utilisant soit des capteurs piezoelectriques (Brevet US n" 4 922 856), soit des capteurs de pression (Brevet PCr W085/01184), soit des détecteurs de proximité métallique. Previous results and work have mainly focused on the methods and methods of coupling these tactile rods to food dispensers, as well as on various methods of producing these tactile rods. Among other methods, there are purely mechanical systems (of the pendulum type), or electromechanical systems using either piezoelectric sensors (US Patent No. 4,922,856), or pressure sensors (PCr Patent W085 / 01184), or metallic proximity.

Or, le principe de fabrication de ces tiges, entrainent soit un coût de fabrication trop élevé (pour les capteurs piezoélectrique ou de pression), soit une mauvaise tenue aux conditions d'environnement en atmosphère humide ou saline (pour les détecteurs métalliques). However, the principle of manufacture of these rods, entails either a too high manufacturing cost (for piezoelectric or pressure sensors), or poor resistance to environmental conditions in a humid or saline atmosphere (for metal detectors).

Intéret de l'invention:
Le système proposé à pour but d'améliorer les performances des tiges tactiles, tout en réduisant leur coût. Pour cela nous avons développé une tige basée sur un procédé nouveau afin d'en simplifier la fabrication et d'améliorer la fiabilité de cette tige tactile.Interest of the invention:
The proposed system aims to improve the performance of tactile rods, while reducing their cost. For this we have developed a rod based on a new process in order to simplify its manufacture and improve the reliability of this tactile rod.

Description:
Le système développé utilise la technologie des capteurs à effet Hall pour transformer en un signal électrique, le mouvement de balancier créé par la poussée ou le mordillement sur une tige (8) partiellement plongée dans le bassin d'élevage, lors de l'excitation par un poisson.Description:
The system developed uses Hall effect sensor technology to transform the pendulum movement created by pushing or nibbling on a rod (8) partially immersed in the breeding tank into an electrical signal, during excitation by a fish.

Compte tenu de la diminution des pièces métalliques, et de l'absence de pièces en contact, la fiabilité est nettement accrue.Given the decrease in metal parts, and the absence of parts in contact, reliability is significantly increased.

I1 comprend un corps formé d'un cylindre rigide (6) dont l'extrémité orientée vers le bassin contenant les poissons, comporte une membrane - souple (7) qui assure l'étanchéité et maintient verticalement une tige(8) qui plonge dans sa partie inférieure dans le bassin d'élevage, et dont l'extrémité supérieure est fermée par un bouchon (3) traversé par le support (2) du capteur à éffet Hall (4), et du cable électrique (1) qui relie la sonde au dispositif d'alimentation. I1 comprises a body formed by a rigid cylinder (6), the end of which faces the basin containing the fish, comprises a flexible membrane (7) which seals and vertically maintains a rod (8) which plunges into its lower part in the breeding tank, and the upper end of which is closed by a plug (3) crossed by the support (2) of the Hall effect sensor (4), and of the electric cable (1) which connects the probe to the feeding device.

Au sommet de la tige (8), soit à l'opposé du coté qui est touché par le poisson, est placée une substance magnétique (5) (aimant ou pastille aimantée), qui dans la position de repos de la sonde est en regard direct avec un capteur à effet Hall (4) de manière à ce que ce dernier soit traversé par le champ magnétique généré par cet aimant. Le capteur à effet Hall étant alors actif, il génère un signal qui rend passant un transistor, et ferme ainsi le circuit électrique. At the top of the rod (8), opposite the side which is touched by the fish, is placed a magnetic substance (5) (magnet or magnetized disc), which in the rest position of the probe is opposite direct with a Hall effect sensor (4) so that the latter is crossed by the magnetic field generated by this magnet. The Hall effect sensor then being active, it generates a signal which turns on a transistor, and thus closes the electrical circuit.

Dès que la tige est excitée, le mouvement de balancier déplace alors l'aimant et coupe de ce fait le champ magnétique qui traversait le capteur et le désactive, ce qui provoque l'ouverture du transistor. As soon as the rod is excited, the pendulum movement then moves the magnet and thereby cuts the magnetic field which passed through the sensor and deactivates it, which causes the transistor to open.

La distance entre l'aimant (5) placé sur la tige mobile, et le capteur (4) intégré à son support peut être ajustée afin de régler la sensibilité de la tige, en vissant ou dévissant le support contenant le capteur (3).  The distance between the magnet (5) placed on the movable rod, and the sensor (4) integrated in its support can be adjusted in order to adjust the sensitivity of the rod, by screwing or unscrewing the support containing the sensor (3).

La souplesse de la tige, ainsi que son retour en position d'équilibre sont effectués gracie à la membrane souple (7), mais dans certains cas, (en particulier pour les tiges lourdes pour les gros poissons) il peut être rajouté des ressorts (11) afin d'assurer un meilleur retour en position d'équilibre. The flexibility of the rod, as well as its return to the equilibrium position are carried out thanks to the flexible membrane (7), but in certain cases, (in particular for the heavy rods for large fish) it can be added springs ( 11) to ensure a better return to the equilibrium position.

Le maintien de la tige tactile au dessus du bassin d'élevage peut être effectué suivant plusieurs méthodes:
- soit au moyen d'un filin qui tient le capteur au niveau de la gorge (12),
- soit grace à un flotteur creux traversé par le corps (6) de la tige tactile,
- soit par un dispositif de maintien fixe
Enfin, l'extrémité de la tige (9) est prévue pour recevoir soit un leurre destiné à provoqua une réaction des poissons, soit un embout spécifique pour être adapté à l'anatollue ou 'au comportement des poissons élevés. The maintenance of the tactile rod above the breeding basin can be carried out according to several methods:
- either by means of a rope which holds the sensor at the level of the groove (12),
- either thanks to a hollow float crossed by the body (6) of the tactile rod,
- either by a fixed holding device
Finally, the end of the rod (9) is intended to receive either a lure intended to provoke a reaction of the fish, or a specific tip to be adapted to the anatollue or 'to the behavior of the reared fish.
