Description
La présente invention concerne un dispositif de détection d’eau dans un système au moins partiellement immergé.The present invention relates to a device for detecting water in an at least partially submerged system.
À titre d’exemple de tels systèmes au moins partiellement immergés, on peut citer en particulier des armes telles que par exemple des torpilles, etc.By way of example of such at least partially submerged systems, mention may be made in particular of weapons such as for example torpedoes, etc.
On sait que ces types de systèmes immergés sont équipés de dispositifs de détection d’eau et en particulier de fuite d’eau, permettant d’éviter toute dégradation de ceux-ci ou à tout le moins, d’avertir le reste des équipements environnants d’un problème lié à une telle présence d’eau.It is known that these types of submerged systems are equipped with devices for detecting water and in particular water leaks, making it possible to avoid any degradation of these or at the very least, to warn the rest of the surrounding equipment. of a problem related to such presence of water.
Dans l’état de la technique de tels dispositifs comportent un capteur de conductivité raccordé à des moyens d’alimentation, de traitement et de transmission d’informations vers le reste des circuits du système.In the state of the art, such devices comprise a conductivity sensor connected to means for supplying, processing and transmitting information to the rest of the circuits of the system.
Mais ceci présente un certain nombre d’inconvénients de structure et de dégradation au fil du temps.But this has a number of structural and degradation disadvantages over time.
Le but de l’invention est donc de résoudre ces problèmes.The object of the invention is therefore to solve these problems.
À cet effet l’invention a pour objet un dispositif de détection d’eau dans un système au moins partiellement immergé, du type comportant un capteur de conductivité, raccordé à des moyens d’alimentation, de traitement et de transmission d’informations, caractérisé en ce qu’un transformateur d’impulsions est interposé entre le capteur et les moyens d’alimentation, de traitement et de transmission, afin d’assurer une isolation galvanique entre ces deux parties du dispositif et limiter fortement une électrolyse du milieu.To this end, the subject of the invention is a device for detecting water in an at least partially submerged system, of the type comprising a conductivity sensor, connected to means for supplying, processing and transmitting information, characterized in that a pulse transformer is interposed between the sensor and the supply, processing and transmission means, in order to ensure galvanic isolation between these two parts of the device and to greatly limit electrolysis of the medium.
Suivant d’autres caractéristiques du système selon l’invention, prises seules ou en combinaison :According to other characteristics of the system according to the invention, taken alone or in combination:
- les moyens de traitement comprennent des moyens de détermination du degré de salinité de l’eau ;the processing means comprise means for determining the degree of salinity of the water;
- il comporte un capteur de température ;it includes a temperature sensor;
- il comporte des moyens de tests/diagnostics de fonctionnement ;it comprises operating test/diagnostic means;
- les moyens de transmission d’informations comprennent un bus numérique ;the information transmission means comprise a digital bus;
- le bus est un bus CAN ;the bus is a CAN bus;
- le système au moins partiellement immergé est un véhicule sous-marin ;the at least partially submerged system is an underwater vehicle;
- le véhicule sous-marin est une torpille.the underwater vehicle is a torpedo.
L’invention sera mieux comprise à l’aide de la description qui va suivre, donnée à titre d’exemple et faite en se référant aux dessins annexés sur lesquels :The invention will be better understood using the following description, given by way of example and made with reference to the appended drawings in which:
-
On a en effet illustré sur cette
Ce dispositif est embarqué par exemple à bord d’un système au moins partiellement immergé tel que par exemple une torpille ou autre comme cela a été indiqué précédemment.This device is embedded for example on board an at least partially submerged system such as for example a torpedo or the like as indicated above.
De façon classique, ce dispositif de détection comporte un capteur de conductivité désigné par la référence générale 2, et raccordé à des moyens d’alimentation, de traitement et de transmission d’informations, désignés par la référence générale 3 sur cette figure.Conventionally, this detection device comprises a conductivity sensor designated by the general reference 2, and connected to means for supplying, processing and transmitting information, designated by the general reference 3 in this figure.
En fait et selon l’invention, un transformateur d’impulsions désigné par la référence générale 4, est interposé entre le capteur 2 et le reste 3 des moyens d’alimentation, de traitement et de transmission d’informations, afin d’assurer une isolation galvanique entre ces deux parties du dispositif et limiter fortement une électrolyse du milieu.In fact and according to the invention, a pulse transformer designated by the general reference 4, is interposed between the sensor 2 and the rest 3 of the means for supplying, processing and transmitting information, in order to ensure a galvanic isolation between these two parts of the device and greatly limit electrolysis of the medium.
Comme cela est illustré, les moyens 3 comportent plusieurs parties et plusieurs moyens remplissant des fonctions d’alimentation, de traitement et de transmission d’informations.As illustrated, the means 3 comprise several parts and several means fulfilling the functions of supplying, processing and transmitting information.
Ainsi par exemple on reconnait sur cette figure, des moyens d’alimentation 5, des moyens de traitement 6 et des moyens de transmission désignés par la référence générale 7.Thus, for example, this figure shows supply means 5, processing means 6 and transmission means designated by the general reference 7.
Ces moyens présentent n’importe quelle structure classique appropriée.These means have any suitable conventional structure.
On notera également que les moyens de traitement par exemple 6 peuvent être raccordés notamment à un capteur de température désigné par la référence générale 8 sur cette figure.It will also be noted that the processing means, for example 6, can be connected in particular to a temperature sensor designated by the general reference 8 in this figure.
Les moyens de transmission d’informations 7 comprennent quant à eux par exemple un bus numérique.The information transmission means 7 for their part comprise, for example, a digital bus.
Différents types de bus peuvent être utilisés et un bus CAN peut être privilégié.Different types of bus can be used and a CAN bus can be preferred.
Le transformateur d’impulsions comporte quant à lui deux parties, à savoir une partie de transformateur d’isolement proprement dite désignée par la référence générale 9 et des parties de génération et de démodulation d’impulsions, désignées par les références générales 10 et 11 sur cette figure.The pulse transformer comprises two parts, namely an isolation transformer part proper designated by the general reference 9 and pulse generation and demodulation parts, designated by the general references 10 and 11 on this figure.
Enfin des moyens de tests et de diagnostics désignés par la référence générale 12 peuvent également être prévus pour permettre un contrôle du fonctionnement de cet ensemble.Finally, test and diagnostic means designated by the general reference 12 can also be provided to allow control of the operation of this assembly.
Comme cela a été indiqué précédemment, ce dispositif de détection peut être embarqué à bord d’un véhicule au moins partiellement immergé tel que par exemple une torpille.As indicated previously, this detection device can be carried on board an at least partially submerged vehicle such as for example a torpedo.
Bien entendu d’autres types de véhicules ou engins sous-marins peuvent être envisagés.Of course, other types of vehicles or underwater vehicles can be considered.
On conçoit alors qu’un tel dispositif présente un certain nombre d’avantages notamment au niveau de l’isolation galvanique apportée entre les deux parties du dispositif et du fait qu’il n’y a quasiment plus d’électrolyse du reste du milieu.It is then conceivable that such a device has a certain number of advantages, in particular at the level of the galvanic isolation provided between the two parts of the device and the fact that there is almost no electrolysis of the rest of the medium.
