La presente invention est relative a un dispositif de transmission d'informations d'un premier systeme vers un deuxieme systeme, du type comprenant un premier circuit resonnant destine a etre relic electriquement au premier systeme et a cooperer avec un deuxieme circuit resonnant appartenant au deuxieme systeme lorsque le deuxieme circuit resonnant est approche du premier circuit resonnant, le deuxieme circuit resonnant etant associe a une The present invention relates to a device for transmitting information from a first system to a second system, of the type comprising a first resonant circuit intended to be electrically connected to the first system and to cooperate with a second resonant circuit belonging to the second system. when the second resonant circuit is approaching the first resonant circuit, the second resonant circuit being associated with a

Dans les dispositifs de transmission d'informations habituellement rencontres, le premier circuit resonnant est adapte pour avoir la meilleure amplitude du signal de communication possible. A cet effet, il possede une In the information transmission devices usually encountered, the first resonant circuit is adapted to have the best amplitude of the communication signal possible. For this purpose, it has a
impedance determinee.determined impedance.
Sous peine de modifier ['impedance et de degrader ['amplitude du signal de communication en dessous d'un seuil de fonctionnement acceptable, il n'est pas possible de relier le premier systeme a un ou plusieurs dispositifs de transmission d'informations supplementaires. Cet inconvenient est un obstacle majeur lors du releve des compteurs, parce qu'il n'est pas toujours possible d'acceder au seul dispositif de transmission implante en un lieu unique. Ce lieu peut etre en effet rendu inaccessible pour differentes raisons et il n'est pas possible de demultiplier le nombre de dispositifs de transmission On pain of modifying the impedance and degrading the amplitude of the communication signal below an acceptable operating threshold, it is not possible to connect the first system to one or more devices for transmitting additional information. This drawback is a major obstacle when reading meters, because it is not always possible to access the only transmission device installed in a single location. This place can indeed be made inaccessible for various reasons and it is not possible to multiply the number of transmission devices
pour augmenter le nombre de points de releve. to increase the number of reading points.
Par ailleurs, I'impossibilite de placer d'autres dispositifs de transmission relies a un meme premier systeme rend la pose de dispositifs de Furthermore, the impossibility of placing other transmission devices connected to the same first system makes the installation of

Grace a ces dispositions, le dispositif de transmission d'informations n'est pas alimente lorsqu'il n'est pas utilise pour transmettre des informations. Par consequent, son fonctionnement n'est pas altere par la presence d'un deuxieme ou d'un troisieme dispositif de transmission To this end, according to the invention, a device for transmitting information of the kind in question is essentially characterized in that it further comprises a switch with reversible magnetic control connected in series with the first resonant circuit, and in that the switch automatically switches to the open or closed position, when the second resonant circuit is respectively far from the first resonant circuit or near this first resonant circuit, so that the first resonant circuit is electrically powered only when the second resonant circuit is approach. Thanks to these provisions, the information transmission device is not powered when it is not used to transmit information. Consequently, its operation is not affected by the presence of a second or a third transmission device

Cet interrupteur a commande magnetique bascule, selon une caracteristique essentielle de ['invention, automatiquement et de fac, on reversible entre sa position fermee (figure 2) et sa position ouverte (figure 3). II est en position ouverte lorsque le deuxieme circuit resonnant est eloigne du premier circuit resonnant et bascule en position fermee, sous ['action de la source de champ magnetique, des que le deuxieme circuit resonnant est approche de ce premier circuit.

Selon un mode prefere de realisation de ['invention, I'interrupteur a commande magnetique 25 comprend au moins une ampoule Reed 26 (figure 2). De maniere encore preferee, le dispositif 1 comprend une deuxieme ampoule Reed 27 (figure 3) placee electriquement en parallele par rapport a la premiere ampoule Reed 26 de maniere a ameliorer la sensibilite de According to a preferred embodiment of the invention, the magnetic control switch 25 comprises at least one Reed bulb 26 (Figure 2).

Les moyens 6 de position nement et de ma i nti en rel atif d u mod u le de couplage sur le bo^,tier de telereport 1 vent sensibles a ['attraction magnetique. Ces moyens de positionnement et de maintien 6 vent situes a l'interieur du bo^,tier 1, entre la surface d'appui 31 et le premier circuit resonnant 5. Ces moyens de position nement prennent la fo rme d 'elements metalliques situes a ['aplomb de la bobine 10 en etant circonferentiellement repartis autour de cette bobine, laissant ainsi des espaces entre eux. Les ampoules Reed 26 et 27 vent situees a ['aplomb des espaces situes entre lesdits elements metalliques de fa,con a ce que les elements metalliques ne The positioning means 6 and ma i nti in relative mode of the coupling module on the bo ^, telereport tier 1 wind sensitive to magnetic attraction. These positioning and holding means 6 wind located inside the bo ^, tier 1, between the bearing surface 31 and the first resonant circuit 5. These positioning means take the form of metallic elements located ['plumb of the coil 10 by being circumferentially distributed around this coil, thus leaving spaces between them. The Reed bulbs 26 and 27 are located above the spaces between the said metallic elements so that the metallic elements do not

De preference, les elements metalliques prennent la forme d'un anneau tronque 40 qui est place concentriquement par rapport a la bobine et a I'aplomb de celle-ci. Cet anneau metallique 40 possede ainsi une portion Preferably, the metal elements take the form of a truncated ring 40 which is placed concentrically with respect to the coil and directly above it. This metal ring 40 thus has a portion
tronquee 41 situee en correspondence des deux ampoules Reed 26 et 27. truncated 41 located in correspondence of the two Reed bulbs 26 and 27.
Les ampoules Reed 26 et 27 vent ainsi rendues accessibles au champ magnetique exerce sur celles-ci lorsque le deuxieme circuit resonnant est approche simultanement a la source de champ magnetique. Afin de rendre encore plus sensibles les deux ampoules Reed au champ magnetique, cellesci vent decalees angulairement autour de la bobine afin d'augmenter la probabilite que l'une des deux soit soumise au champ magnetique. De preference, la deuxieme ampoule Reed 27 est decalee par Reed bulbs 26 and 27 wind thus made accessible to the magnetic field exerted on them when the second resonant circuit is approached simultaneously to the source of magnetic field. In order to make the two Reed bulbs even more sensitive to the magnetic field, they are offset angularly around the coil in order to increase the probability that one of the two is subjected to the magnetic field. Preferably, the second Reed 27 bulb is offset by
rapport a la premiere ampoule Reed 26 de la moitie de sa longueur. compared to the first Reed 26 bulb, half its length.
Grace a la presence des ampoules Reed 26 et 27, le premier circuit resonnant 5 est en permanence ouvert tent qu'un champ magnetique n'est pas exerce. Lorsque l'on veut proceder au releve des compteurs, le module de couplage est mis en butee sur la surface 31 du couvercle 3, de sorte que les aimants du module de couplage permettent a la fois d'immobiliser le module de couplage sur le bo^'tier 3 et de provoquer la fermeture des ampoules Reed 26 et 27. Le premier circuit resonnant 5 est alors electriquement ferme et les Thanks to the presence of Reed bulbs 26 and 27, the first resonant circuit 5 is permanently open tent that a magnetic field is not exerted. When it is desired to read the meters, the coupling module is brought into abutment on the surface 31 of the cover 3, so that the magnets of the coupling module allow both to immobilize the coupling module on the bo ^ 'tier 3 and cause the closure of the Reed bulbs 26 and 27. The first resonant circuit 5 is then electrically closed and the
informations vent transmises au deuxieme circuit resonnant. wind information transmitted to the second resonant circuit.
Puisque le premier circuit resonnant 5 n'est ferme que lorsqu'il est sollicite par la presence du champ magnetique, c'est-a-dire uniquement au moment du releve, il est possible d'incorporer d'autres dispositifs de transmission en parallele sur le meme cable sans perturber le fonctionnement de chacun de ces dispositifs. Ces dispositifs supplementaires peuvent etre Since the first resonant circuit 5 is closed only when it is requested by the presence of the magnetic field, that is to say only at the time of reading, it is possible to incorporate other transmission devices in parallel on the same cable without disturbing the operation of each of these devices. These additional devices can be
