Description

COUPE-CIRCUIT DE BATTERIE D'ACCUMULATEUR COMMANDE A DISTANCE REMOTE CONTROL BATTERY CUTTER CIRCUIT BREAKER
DOMAINE TECHNIQUE AUQUEL SE RAPPORTE L'INVENTION La présente invention concerne de manière générale les coupe-circuit. Elle concerne plus particulièrement un coupe-circuit comportant une borne électrique d'entrée destinée à être reliée à une batterie d'accumulateur, une borne électrique de sortie, des moyens de contact adaptés à fermer ou à ouvrir le contact électrique entre les deux bornes électriques d'entrée et de sortie, des moyens de verrouillage et de déverrouillage des moyens de contact, et des moyens de réception à distance d'au moins un signal de commande des moyens de verrouillage et de déverrouillage. L'invention trouve une application particulièrement avantageuse pour les engins motorisés dont le maniement est dangereux et dont le moteur principal est démarré au moyen d'un moteur électrique de démarrage alimenté par une batterie d'accumulateur.TECHNICAL FIELD TO WHICH THE INVENTION RELATES The present invention relates generally to circuit breakers. It relates more particularly to a circuit breaker comprising an electrical input terminal intended to be connected to an accumulator battery, an electrical output terminal, contact means adapted to close or to open the electrical contact between the two electrical terminals. input and output means, means for locking and unlocking the contact means, and means for remote reception of at least one control signal of the locking and unlocking means. The invention finds a particularly advantageous application for motor vehicles whose handling is dangerous and whose main motor is started by means of an electric starter motor powered by a storage battery.
ARRIÈRE-PLAN TECHNOLOGIQUE On connaît du document GB 2 284 018 un coupe-circuit du type précité dont les moyens de verrouillage et de déverrouillage, lorsqu'ils sont dans un état de verrouillage, empêchent les moyens de contact du coupe-circuit d'être amenés dans leur position de fermeture du contact électrique entre les deux bornes électriques d'entrée et de sortie. Ces moyens de verrouillage et de déverrouillage forment dans ce document une porte logique de type OR qui, à la réception par les moyens de réception d'un signal donné, met le coupe-circuit dans un état d'interdiction de fermeture du contact électrique entre les deux bornes électriques d'entrée et de sortie. Ce type de coupe-circuit est en particulier efficace contre le vol de véhicules. En effet, dans ce cas, les moyens de contact du coupe-circuit ne doivent pouvoir être déverrouillés qu'à la seule et unique condition qu'aucune effraction n'est commise sur le véhicule.BACKGROUND OF THE PRIOR ART Document GB 2 284 018 discloses a circuit breaker of the aforementioned type whose locking and unlocking means, when in a state of locking, prevent the contact means of the circuit breaker from being blocked. brought into their closed position of the electrical contact between the two electrical input and output terminals. These locking and unlocking means form in this document a logic gate type OR which, upon reception by the receiving means of a given signal, puts the circuit breaker in a closed state of closure of the electrical contact between the two electrical input and output terminals. This type of circuit breaker is particularly effective against vehicle theft. In this case, the contact means of the circuit breaker can only be unlocked on the sole condition that no tampering occurs on the vehicle.
Toutefois, dans le cadre du maniement d'engins motorisés dangereux, la batterie de démarrage du moteur principal de l'engin ne doit pouvoir être activée que lorsque toutes les conditions de sécurité requises sont réunies. En effet, préalablement à la mise en marche d'engins motorisés dangereux, il est toujours nécessaire de vérifier l'état normal de différents paramètres du véhicule et/ou de son environnement.However, in the case of handling dangerous motorized vehicles, the starter battery of the main engine of the vehicle must only be activated when all the necessary safety conditions are met. Indeed, prior to the start of dangerous motorized vehicles, it is always necessary to check the normal state of various parameters of the vehicle and / or its environment.
Avec un coupe-circuit du type précité, cette vérification n'est réalisée qu'au moyen d'un seul signal reçu par les moyens de réception, ce qui n'est pas suffisant du point de vue de la sécurité.With a circuit breaker of the aforementioned type, this verification is performed only by means of a single signal received by the receiving means, which is not sufficient from the point of view of safety.
En effet, si le signal est émis par une seule personne, il est probable qu'à un moment donné, cette personne oubliera de vérifier l'état d'un des paramètres de sécurité du véhicule, ce qui pourra avoir de fâcheuses conséquences. D'autre part, si le signal est émis par un seul et unique dispositif électronique, lorsque ce dernier présentera des dysfonctionnements, la vérification de l'état des paramètres de sécurité du véhicule ne sera absolument pas fiable.Indeed, if the signal is emitted by a single person, it is likely that at some point, this person will forget to check the status of one of the security parameters of the vehicle, which could have unfortunate consequences. On the other hand, if the signal is emitted by a single electronic device, when the latter has malfunctions, the verification of the state of the vehicle safety parameters will be absolutely unreliable.
OBJET DE L'INVENTIONOBJECT OF THE INVENTION
La présente invention propose un nouveau coupe-circuit dans lequel le verrouillage et le déverrouillage des moyens de contact confèrent au coupe-circuit un bon niveau de sécurité.The present invention proposes a new circuit breaker in which the locking and unlocking of the contact means give the circuit breaker a good level of safety.
À cet effet, on propose selon l'invention un coupe-circuit dans lequel les moyens de verrouillage et de déverrouillage sont conçus pour être dans un état de déverrouillage des moyens de contact après réception de plusieurs signaux de commande distincts et prédéterminés.For this purpose, there is provided according to the invention a circuit breaker in which the locking and unlocking means are designed to be in an unlocked state of the contact means after receiving several distinct and predetermined control signals.
Dans un souci de sécurité, les moyens de verrouillage et de déverrouillage sont ainsi conçus pour rester dans un état de verrouillage des moyens de contact tant que plusieurs signaux ne valident pas ensemble l'état normal de tous les paramètres de sécurité du véhicule. Par conséquent, tant qu'au moins une des conditions de sécurité n'est pas validée, les moyens de verrouillage et de déverrouillage verrouillent le coupe-circuit dans une configuration d'ouverture du contact électrique.For reasons of safety, the locking and unlocking means are thus designed to remain in a locking state of the contact means as long as several signals do not validate together the normal state of all the vehicle safety parameters. Therefore, as long as at least one of the safety conditions is not validated, the locking and unlocking means lock the circuit breaker in an opening configuration of the electrical contact.
Les moyens de contact peuvent ici être déverrouillés à distance ce qui offre une grande souplesse d'utilisation pour chaque utilisateur et un gain de temps important par rapport à un système classique à clefs.The contact means can here be unlocked remotely which offers a great flexibility of use for each user and a significant time saving compared to a conventional key system.

- les moyens de déverrouillage sont conçus pour être dans un état de verrouillage des moyens de contact à la réception d'au moins un autre signal de commande prédéterminé ;the unlocking means are designed to be in a locking state of the contact means upon receipt of at least one other predetermined control signal;
- le coupe-circuit comprend des moyens d'émission d'un signal sonore adaptés à émettre ledit signal sonore lorsque les moyens de réception à distance reçoivent un signal de commande prédéterminé de verrouillage des moyens de verrouillage et de déverrouillage ;the circuit breaker comprises means for transmitting a sound signal adapted to emit said sound signal when the remote reception means receive a predetermined control signal for locking the locking and unlocking means;
- Le coupe-circuit comporte des moyens de mémorisation de chaque signal de commande reçu ;- The circuit breaker comprises means for storing each received control signal;

Sur les dessins annexés :DETAILED DESCRIPTION OF AN EXEMPLARY EMBODIMENT The following description with reference to the accompanying drawings of an embodiment, given by way of non-limiting example, will make it clear what the invention consists of and how it can be achieved. In the accompanying drawings:
- la figure 1 est une vue d'ensemble schématique du coupe-circuit selon l'invention relié, d'une part, à une batterie, et, d'autre part, à une motorisation ; et, - la figure 2 est une vue en perspective de l'intérieur d'un boîtier du coupe- circuit de la figure 1.- Figure 1 is a schematic overview of the circuit breaker according to the invention connected, on the one hand, to a battery, and on the other hand, to a motor; and, FIG. 2 is a perspective view of the inside of a casing of the circuit breaker of FIG. 1.
Sur la figure 1 on a représenté une partie d'un engin motorisé qui comprend un coupe-circuit 1 pourvu d'une borne électrique d'entrée 10 reliée à une batterie d'accumulateur 100 et une borne électrique de sortie 20. Cette borne électrique de sortie 20 est reliée à un alternateur 91 , lui-même relié à un moteur principal 90, de manière que lorsque le moteur principal 90 fonctionne, la batterie d'accumulateur 100 est rechargée au moyen de l'alternateur 91. La borne électrique de sortie 20 est également reliée à un moteur électrique de démarrage 92, de manière que lorsque le contact électrique est fermé entre les deux bornes électriques du coupe-circuit 1 , la batterie d'accumulateur 100 alimente le moteur électrique de démarrage 92 qui est alors apte à démarrer le moteur principal 90.FIG. 1 shows a part of a motorized machine which comprises a circuit breaker 1 provided with an electrical input terminal 10 connected to an accumulator battery 100 and an electrical output terminal 20. This electrical terminal outlet 20 is connected to an alternator 91, itself connected to a main motor 90, so that when the main motor 90 operates, the accumulator battery 100 is recharged by means of the alternator 91. The electrical terminal of output 20 is also connected to an electric starter motor 92, so that when the electrical contact is closed between the two electrical terminals of the circuit breaker 1, the accumulator battery 100 supplies the electric starter motor 92 which is then suitable to start the main engine 90.
Ce coupe-circuit comporte également des moyens de contact 3 adaptés à fermer ou à ouvrir le contact électrique entre les deux bornes électriques d'entrée 10 et de sortie 20. La structure de ces moyens de contact 3 et leur agencement dans le coupe-circuit 1 sont décrits ci-dessous.This circuit breaker also comprises contact means 3 adapted to close or open the electrical contact between the two electrical input terminals 10 and 20 output. The structure of these contact means 3 and their arrangement in the circuit breaker 1 are described below.
Comme le montre la figure 2, le coupe-circuit 1 comporte un boîtier 1A de forme parallélépipédique formé par deux parties distinctes destinées à être emboîtées l'une au-dessus de l'autre pour définir intérieurement un logement 1 B. Sur une de ses parois latérales, le boîtier 1A porte les deux bornes électriques d'entrée 10 et de sortie 20 qui sont identiques et qui présentent chacune un corps 11 , 21 de forme allongée s'étendant de l'intérieur du boîtier 1A jusqu'au-delà de sa paroi latérale.As shown in Figure 2, the circuit breaker 1 comprises a parallelepiped shaped casing 1A formed by two separate parts intended to be fitted one above the other to define a housing 1 B internally. On one of its side walls, the housing 1A carries the two electrical input and output terminals 20 which are identical and which each have a body 11, 21 of elongate shape extending from the inside of the housing 1A to beyond its side wall.
Une première extrémité de chacun de ces corps 11 , 21, celle disposée à l'intérieur du boîtier 1A, est raccordée à un élément contacteur 12, 22 fixe.A first end of each of these bodies 11, 21, that disposed inside the housing 1A, is connected to a fixed contact element 12, 22.
Les deux éléments contacteurs 12, 22 présentent une section carrée et une faible épaisseur, et forment chacun une face plane tournée vers l'intérieur du boîtier 1A.The two contactor elements 12, 22 have a square section and a small thickness, and each form a flat face facing the interior of the housing 1A.
L'autre extrémité de chacun de ces corps 11 , 21 est percée d'un logement intérieur cylindrique débouchant d'axe confondu avec celui du corps 11 ,The other end of each of these bodies 11, 21 is pierced with a cylindrical inner housing opening with an axis coinciding with that of the body 11,
21 de chaque borne. Les bornes électriques d'entrée 10 et de sortie 20 présentent par conséquent, du côté de leur autre extrémité, des parois tubulaires de faible épaisseur. Chaque logement est adapté à accueillir des extrémités dénudées de câbles d'alimentation électrique (non représentés). La borne électrique d'entrée 10 du coupe-circuit 1 peut par conséquent être raccordée électriquement à la batterie d'accumulateur 100 par un de ces câbles d'alimentation électrique et la borne électrique de sortie peut être raccordée au moteur électrique de démarrage 92 du moteur principal 90 de l'engin.21 from each terminal. The electrical input and output terminals 20 therefore have, at their other end, thin tubular walls. Each housing is adapted to accommodate stripped ends of power supply cables (not shown). The electrical input terminal 10 of the circuit breaker 1 can therefore be electrically connected to the accumulator battery 100 by one of these power supply cables and the electrical output terminal can be connected to the starting electric motor 92 of the main motor 90 of the machine.
Les deux bornes électriques d'entrée 10 et de sortie 20 sont ici réalisées d'une seule pièce en cuivre argenté.The two electrical input and output terminals 20 are here made of a single piece of silver copper.
Le logement 1 B accueille l'ensemble des appareillages électriques du coupe-circuit 1. Un de ces appareillages électriques constitue des moyens de contact 3 adaptés à fermer ou à ouvrir le contact électrique entre les deux bornes électriques d'entrée 10 et de sortie 20 du coupe-circuit 1.The housing 1 B accommodates all the electrical equipment of the circuit breaker 1. One of these electrical devices is contact means 3 adapted to close or open the electrical contact between the two electrical input terminals 10 and 20 output circuit breaker 1.
Ces moyens de contact comprennent en particulier un pont de contact 3 constituant une poutrelle de section en U dont les deux branches sont orientées vers l'intérieur du boîtier 1A et dont la face supérieure est tournée vers les faces planes des éléments contacteurs 12, 22 des bornes électriques d'entrée 10 et de sortie 20. Ce pont de contact 3 présente une longueur qui permet à sa face supérieure de pouvoir simultanément entrer en contact avec les deux faces planes des éléments contacteurs 12, 22. Le pont de contact 3 présente par ailleurs sur sa face supérieure une ouverture centrale permettant sa solidarisation à un arbre mobile 2A. Cet arbre mobile 2A présente à mi-hauteur une collerette 4 et à une de ses extrémités une partie filetée. Un ressort de compression 5 est engagé sur cet arbre de manière à prendre appui contre la collerette 4. Le pont de contact 3 est quant à lui positionné contre ce ressort de compression 5. Un écrou 6 est vissé sur la partie filetée de l'arbre mobile 2A de manière à maintenir le pont de contact 3 contre le ressort de compression 5.These contact means comprise in particular a contact bridge 3 constituting a U-section beam whose two branches are oriented towards the inside of the housing 1A and whose upper face faces the flat faces of the contact elements 12, 22 of the electrical terminals input 10 and output 20. This contact bridge 3 has a length which allows its upper face to simultaneously be in contact with the two planar faces of the contact elements 12, 22. The contact bridge 3 present by elsewhere on its upper face a central opening for securing it to a movable shaft 2A. This movable shaft 2A has at mid-height a flange 4 and at one of its ends a threaded portion. A compression spring 5 is engaged on this shaft so as to bear against the flange 4. The contact bridge 3 is positioned against this compression spring 5. A nut 6 is screwed onto the threaded portion of the shaft 2A so as to maintain the contact bridge 3 against the compression spring 5.
L'arbre mobile 2A est adapté à se translater entre deux positions stables. Dans une première position stable, le pont de contact 3 est disposé à distance des éléments contacteurs 12, 22, et dans une seconde position stable, le pont de contact 3 est en appui contre les faces planes de ces éléments contacteurs. L'arbre mobile 2A est de préférence réalisé en matériau amagnétique.The movable shaft 2A is adapted to translate between two stable positions. In a first stable position, the contact bridge 3 is disposed at a distance from the contacting elements 12, 22, and in a second stable position, the contact bridge 3 bears against the flat faces of these contact elements. The movable shaft 2A is preferably made of non-magnetic material.
Le ressort de compression 5 sert, lorsque l'arbre mobile 2A est en deuxième position stable, à correctement maintenir le pont de contact 3 contre les éléments contacteurs 12, 22 pour que le passage du courant électrique d'un borne électrique à l'autre engendre peu de pertes résistives.The compression spring 5 serves, when the movable shaft 2A is in second stable position, to correctly maintain the contact bridge 3 against the contacting elements 12, 22 so that the passage of electrical current from one electrical terminal to the other generates few resistive losses.
Un dispositif de manœuvre bistable 2 de forme cylindrique est raccordé à l'arbre mobile 2A et est apte à le déplacer en translation entre ses première et deuxième positions stables.A cylindrical bistable operating device 2 is connected to the movable shaft 2A and is able to move it in translation between its first and second stable positions.
Le boîtier 1A comporte également intérieurement un circuit électronique 30 de commande du dispositif de manœuvre bistable 2. Ce circuit électronique 30 comporte en particulier un microprocesseur.The housing 1A also internally comprises an electronic circuit 30 for controlling the bistable operating device 2. This electronic circuit 30 comprises in particular a microprocessor.
L'ensemble des appareillages électriques que contient le boîtier 1A permet donc d'ouvrir et de fermer le contact électrique entre la batterie d'accumulateur 100 et le moteur électrique de démarrage du moteur principal 90.The set of electrical equipment contained in the housing 1A thus makes it possible to open and close the electrical contact between the accumulator battery 100 and the electric motor for starting the main motor 90.
Le coupe-circuit comprend également des moyens de verrouillage et de déverrouillage (non représentés) des moyens de contact 3. Le verrouillage des moyens de contact 3 empêche les moyens de contact 3 d'être amenés en position de fermeture du contact électrique. Les moyens de verrouillage et de déverrouillage peuvent être constitués par un dispositif électromécanique en liaison d'une part avec les moyens de contact 3 et d'autre part avec le circuit électronique 30 qui commande alors ce dispositif électromécanique.The circuit breaker also comprises locking and unlocking means (not shown) of the contact means 3. The locking of the contact means 3 prevents the contact means 3 from being brought into the closed position of the electrical contact. The locking and unlocking means may be constituted by an electromechanical device connected on the one hand with the contact means 3 and on the other hand with the electronic circuit 30 which then controls the electromechanical device.
Avantageusement selon l'invention, le coupe-circuit comporte des moyens de réception à distance 40 de signaux de commande de ces moyens de verrouillage et de déverrouillage. Ici, ces moyens de réception à distance 40 comprennent un récepteur radio 40. Le récepteur radio 40 du coupe-circuit 1 comporte un fil électrique de communication 42 relié au circuit électronique 30 et une antenne 41. Comme le montre plus particulièrement la figure 2, cette antenne s'étend du récepteur radio 40 jusqu'en dehors du boîtier 1A du coupe-circuit 1.Advantageously according to the invention, the circuit breaker comprises remote reception means 40 of control signals of these locking and unlocking means. Here, these remote reception means 40 comprise a radio receiver 40. The radio receiver 40 of the circuit breaker 1 comprises an electric communication wire 42 connected to the electronic circuit 30 and an antenna 41. As shown more particularly in FIG. this antenna extends from the radio receiver 40 to outside the casing 1A of the circuit breaker 1.
L'extrémité de cette antenne est disposée dans l'engin motorisé de telle sorte que les signaux radio reçus ne soient pas amortis par la caisse métallique de l'engin.The end of this antenna is arranged in the motorized machine so that the radio signals received are not damped by the metal body of the machine.
Chaque signal de commande des moyens de verrouillage et de déverrouillage est constitué par un signal radio prédéterminé et distinct des autres signaux. Les moyens de verrouillage et de déverrouillage, dans un état de verrouillage des moyens de contact, sont conçus pour passer dans un état de déverrouillage des moyens de contact uniquement après réception des signaux de commande distincts et prédéterminés. Pour s'assurer que tous les signaux de commande distincts et prédéterminés, ici les signaux radio, ont été reçus, le circuit électronique 30 comporte des moyens de mémorisation des signaux de commande reçus.Each control signal of the locking and unlocking means is constituted by a predetermined radio signal and distinct from the other signals. The locking and unlocking means, in a locking state of the contact means, are designed to go into an unlocking state of the contact means only after receiving distinct and predetermined control signals. To ensure that all separate and predetermined control signals, here the radio signals, have been received, the circuit electronics 30 includes means for storing the received control signals.
Il est également prévu des moyens d'émission à distance 70 de ces signaux de commande distincts et prédéterminés. Ici les moyens d'émission à distance 70 sont constitués par des émetteurs radio 70 adaptés à émettre les signaux radio prédéterminés et distincts. Chaque émetteur a une portée d'environ 100 mètres. Chaque émetteur radio 70 est confié à une personne qui, après avoir établi que les conditions de sécurité concernant son domaine sont respectées, émet un signal radio à partir de l'émetteur radio 70. Le récepteur radio 40 reçoit alors le signal radio prédéterminé qui est mémorisé par le circuit électronique 30. Après réception de l'ensemble des signaux prédéterminés, le circuit électronique 30 commande aux moyens de verrouillage et de déverrouillage le déverrouillage des moyens de contact 3.Remote transmission means 70 are also provided for these distinct and predetermined control signals. Here the remote transmission means 70 are constituted by radio transmitters 70 adapted to emit the predetermined and distinct radio signals. Each transmitter has a range of about 100 meters. Each radio transmitter 70 is entrusted to a person who, having established that the security conditions concerning his domain are respected, transmits a radio signal from the radio transmitter 70. The radio receiver 40 then receives the predetermined radio signal which is memorized by the electronic circuit 30. After receiving all the predetermined signals, the electronic circuit 30 controls the locking and unlocking means unlocking the contact means 3.
L'utilisateur est alors en mesure d'activer la batterie d'accumulateurs par la commande de fermeture du contact électrique entre les bornes d'entrée et de sortie du coupe-circuit.The user is then able to activate the storage battery by the closing command of the electrical contact between the input and output terminals of the circuit breaker.
On peut aussi prévoir que les moyens de verrouillage et de déverrouillage soient directement intégrés au circuit électronique 30, c'est-à-dire que les moyens de verrouillage et de déverrouillage correspondent à deux états du circuit électronique 30. Dans le premier état, qui est un état de verrouillage des moyens de contact 3, le circuit électronique 30 n'autorise pas les moyens de contact 3 à fermer le contact électrique entre les deux bornes d'entrée et de sortie tant que les signaux radio prédéterminés n'ont pas tous été reçus. Dans le deuxième état, qui est un état de déverrouillage, le circuit électronique autorise les moyens de contact 3 à fermer le contact électrique entre les deux bornes d'entrée et de sortie, ce qui est obtenu lorsque tous les signaux radio prédéterminés ont été reçus. Ainsi, dans ce cas, le verrouillage des moyens de contact et la mémorisation des signaux commandant l'état de verrouillage ou de déverrouillage des moyens de contact sont réalisés directement par le microprocesseur qui est programmé à cet effet.It can also be provided that the locking and unlocking means are directly integrated in the electronic circuit 30, that is to say that the locking and unlocking means correspond to two states of the electronic circuit 30. In the first state, which is a state of locking of the contact means 3, the electronic circuit 30 does not allow the contact means 3 to close the electrical contact between the two input and output terminals until the predetermined radio signals do not all been received. In the second state, which is an unlock state, the electronic circuit allows the contact means 3 to close the electrical contact between the two input and output terminals, which is obtained when all the predetermined radio signals have been received. . Thus, in this case, the locking of the contact means and the memorization of the signals controlling the state of locking or unlocking of the contact means are made directly by the microprocessor which is programmed for this purpose.
En pratique, chaque émetteur radio peut être constitué d'un petit boîtier comprenant un quartz qui est excité à une fréquence prédéterminée, différente pour chaque émetteur, lorsque l'utilisateur appuie sur un bouton du boîtier. Le signal radio prédéterminé est alors constitué par la fréquence radio d'émission. Le récepteur radio peut comporter plusieurs quartz excités chacun, à une fréquence différente, lors de la réception du signal radio de fréquence prédéterminée correspondante. Une fois tous les quartz excités, le circuit électronique est apte à commander le passage des moyens de verrouillage et de déverrouillage dans leur état de déverrouillage des moyens de contact. Dans ce cas, chaque signal radio est caractérisé par sa fréquence.In practice, each radio transmitter may consist of a small housing comprising a quartz which is excited at a predetermined frequency, different for each transmitter, when the user presses a button of the housing. The predetermined radio signal is then constituted by the radio transmission frequency. The The radio receiver may comprise a plurality of crystals each excited at a different frequency upon reception of the corresponding predetermined frequency radio signal. Once all the quartz excited, the electronic circuit is able to control the passage of the locking and unlocking means in their unlocked state of the contact means. In this case, each radio signal is characterized by its frequency.
Dans un souci de sécurité, les moyens de verrouillage et de déverrouillage peuvent également être conçus pour être dans un état de verrouillage des moyens de contact 3 à la réception d'au moins un autre signal de commande prédéterminé. Cet autre signal peut être l'un des signaux prédéterminés qui participent au déverrouillage des moyens de contact ou bien un signal distinct. Ainsi, lorsqu'une personne qui dispose d'un émetteur radio s'aperçoit après avoir émis le signal radio prédéterminé relatif au domaine de sécurité qui le concerne, qu'en réalité au moins une des conditions de sécurité nécessaire au démarrage de l'engin n'est pas respectée, cette personne peut émettre un nouveau signal qui verrouille le coupe-circuit dans une configuration d'ouverture du contact électrique pour empêcher le démarrage du moteur principal de l'engin.For security reasons, the locking and unlocking means may also be designed to be in a locking state of the contact means 3 upon receipt of at least one other predetermined control signal. This other signal may be one of the predetermined signals that participate in the unlocking of the contact means or a separate signal. Thus, when a person who has a radio transmitter sees after issuing the predetermined radio signal relating to the security field that concerns him, that in fact at least one of the security conditions necessary for starting the machine is not respected, this person can emit a new signal that locks the circuit breaker in an opening configuration of the electrical contact to prevent the starting of the main engine of the machine.
En variante, on peut prévoir que le signal de commande émis peut-être plus complexe pour éviter toute interférence ou erreur d'interprétation du signal reçu. Pour cela, le signal radio peut comprendre des informations relatives à un identifiant prédéterminé mémorisé dans le circuit électronique du coupe-circuit.Alternatively, it can be provided that the transmitted control signal may be more complex to avoid any interference or interpretation error of the received signal. For this, the radio signal may comprise information relating to a predetermined identifier stored in the electronic circuit of the circuit breaker.
Dans ce cas, le coupe-circuit comprend des moyens d'enregistrement d'identifiants prédéterminés, ainsi que des moyens de traitement du signal, par exemple intégrés au circuit électronique, adaptés à transformer le signal radio reçu par le récepteur radio en informations relatives à un identifiant. En d'autres termes, après réception du signal radio par le récepteur radio, le circuit électronique extrait l'identifiant compris dans le signal radio reçu.In this case, the circuit breaker comprises means for recording predetermined identifiers, as well as signal processing means, for example integrated in the electronic circuit, adapted to transform the radio signal received by the radio receiver into information relating to a login. In other words, after reception of the radio signal by the radio receiver, the electronic circuit extracts the identifier included in the received radio signal.
Le coupe-circuit peut également comporter des moyens de comparaison de l'identifiant obtenu après traitement du signal reçu avec chaque identifiant enregistré, pour valider l'identifiant obtenu. Une fois tous les identifiants reçus et validés, le circuit électronique est apte à commander le passage des moyens de verrouillage et de déverrouillage dans un état de déverrouillage des moyens de contact. Une application du coupe-circuit selon l'invention est décrite ci-dessous pour un engin motorisé de grande dimension, par exemple destiné à une utilisation minière.The circuit breaker may also include means for comparing the identifier obtained after processing the received signal with each registered identifier, to validate the identifier obtained. Once all the identifiers received and validated, the electronic circuit is able to control the passage of the locking and unlocking means in an unlocked state of the contact means. An application of the circuit breaker according to the invention is described below for a motorized machine of large size, for example intended for a mining use.
Une première personne qui possède un premier émetteur arrive pour effectuer une première intervention, par exemple une intervention hydraulique. Si les moyens de contact sont fermés, elle appuie sur un bouton relié au coupe- circuit qui permet d'ouvrir les moyens de contact. Cette personne appuie alors sur un bouton (par exemple identifié par le terme LOCK sur l'émetteur) de son premier émetteur pour émettre le premier signal prédétermiηé qui est associé à ce premier émetteur. Le premier signal prédéterminé est reconnu et mémorisé par le microprocesseur ce qui active un premier verrou électronique associé à ce signal prédéterminé, c'est-à-dire que la carte électronique est dans un état spécifique à la réception de ce premier signal prédéterminé qui verrouille les moyens de contact dans leur état ouvert. Une deuxième personne qui possède un deuxième émetteur arrive pour effectuer une intervention, par exemple une intervention électrique. Comme précédemment, cette deuxième personne appuie alors sur le bouton LOCK de ce deuxième émetteur pour émettre un deuxième signal prédéterminé, distinct du premier signal prédéterminé, qui est associé à ce deuxième émetteur. Le deuxième signal prédéterminé est reconnu et mémorisé par le microprocesseur ce qui active un deuxième verrou électronique associé à ce signal, c'est-à-dire que la carte électronique est dans un état spécifique à la réception de ce deuxième signal prédéterminé en plus du premier signal prédéterminé. A lui seul, ce deuxième signal entraîne le verrouillage des moyens de contact dans leur état ouvert. La carte électronique ayant mémorisé les deux signaux prédéterminés, le verrouillage des moyens de contact est réalisé par les deux verrous électroniques qui sont indépendants (les deux signaux prédéterminés étant distincts).A first person who has a first transmitter arrives to perform a first intervention, for example a hydraulic intervention. If the contact means are closed, it presses a button connected to the circuit breaker which opens the contact means. This person then presses a button (for example identified by the term LOCK on the transmitter) of its first transmitter to emit the first predetermined signal that is associated with the first transmitter. The first predetermined signal is recognized and stored by the microprocessor which activates a first electronic lock associated with this predetermined signal, that is to say that the electronic card is in a specific state to receive the first predetermined signal that locks the contact means in their open state. A second person who has a second transmitter arrives to perform an intervention, such as electrical intervention. As before, this second person then presses the LOCK button of this second transmitter to emit a second predetermined signal, distinct from the first predetermined signal, which is associated with the second transmitter. The second predetermined signal is recognized and stored by the microprocessor which activates a second electronic lock associated with this signal, that is to say that the electronic card is in a specific state to receive this second predetermined signal in addition to the first predetermined signal. By itself, this second signal causes the locking of the contact means in their open state. The electronic card having stored the two predetermined signals, the locking of the contact means is achieved by the two electronic locks which are independent (the two predetermined signals being distinct).
Ainsi, quand une des deux personnes a effectué son intervention, par exemple la première personne, celle-ci appui sur un autre bouton de son émetteur (par exemple identifié par le terme UNLOCK sur l'émetteur) pour émettre un signal supplémentaire prédéterminé, distinct du deuxième signal prédéterminé, qui peut être distinct ou non du premier signal dont la première émission a permis de verrouiller les moyens de contact. Dans le cas où le signal supplémentaire émis est le même que le premier signal, le bouton LOCK et le bouton UNLOCK peuvent être confondus. La réception de ce signal supplémentaire par le microprocesseur annule le verrouillage associé au premier signal reçu, mais pas le verrouillage associé au deuxième signal reçu du deuxième émetteur ce qui laisse la carte électronique dans un état spécifique à la réception du deuxième signal prédéterminé qui conserve le verrouillage des moyens de contact dans leur état ouvert.Thus, when one of the two persons has performed his intervention, for example the first person, the latter person presses another button of its transmitter (for example identified by the word UNLOCK on the transmitter) to emit a predetermined additional distinct signal the second predetermined signal, which may or may not be distinct from the first signal whose first transmission has made it possible to lock the contact means. In the case where the additional signal sent is the same as the first signal, the LOCK button and the UNLOCK button can to be confused. The reception of this additional signal by the microprocessor cancels the lock associated with the first signal received, but not the lock associated with the second signal received from the second transmitter which leaves the electronic card in a specific state to receive the second predetermined signal which retains the locking the contact means in their open state.
Lorsque la deuxième personne a effectué son intervention, celle-ci appuie comme précédemment sur le bouton UNLOCK de son deuxième émetteur ce qui annule le verrouillage associé au deuxième signal reçu. Or le verrouillage associé au premier signal reçu du premier émetteur a été précédemment enlevé ce qui laisse la carte électronique dans un état de déverrouillage des moyens de contact dans leur état ouvert.When the second person has made his intervention, it supports as before the button UNLOCK of its second transmitter which cancels the lock associated with the second signal received. But the lock associated with the first signal received from the first transmitter has been previously removed which leaves the electronic card in a state of unlocking the contact means in their open state.
Le microprocesseur passe alors dans un mode prêt à effectuer une fermeture des moyens de contact lorsqu'une commande ultérieure adaptée est reçue. Cette commande peut se faire par un bouton relié par un fil au coupe-circuit, ou par un bouton sur un émetteur dédié, ou encore par le bouton UNLOCK d'un des émetteurs de signaux prédéterminés.The microprocessor then goes into a mode ready to close the contact means when a suitable subsequent command is received. This command can be done by a button connected by a wire to the circuit breaker, or by a button on a dedicated transmitter, or by the UNLOCK button of one of the predetermined signal transmitters.
Pour des raisons de sécurité, le coupe-circuit peut comprendre des moyens d'émission d'un signal sonore adaptés à émettre ledit signal sonore lorsque les moyens de réception à distance reçoivent le signal de commande prédéterminé de verrouillage des moyens de verrouillage et de déverrouillage correspondant à un des émetteurs. Ainsi lorsque l'une des personnes arrive pour effectuer son intervention et appuie sur le bouton LOCK de son émetteur, le signal sonore émis par le coupe-circuit lui confirme que les moyens de verrouillage et de déverrouillage sont bien dans un état de verrouillage des moyens de contact dans leur position d'ouverture.For safety reasons, the circuit breaker may comprise means for emitting a sound signal adapted to emit said sound signal when the remote reception means receive the predetermined control signal for locking the locking and unlocking means. corresponding to one of the transmitters. Thus, when one of the persons arrives to perform his intervention and presses the LOCK button on his transmitter, the acoustic signal emitted by the circuit breaker confirms that the locking and unlocking means are in a locked state of the means. contact in their open position.
Enfin, on peut prévoir un émetteur supplémentaire qui, par appui sur un bouton dédié de cet émetteur, émet un signal adapté à déverrouiller les moyens de verrouillage et de déverrouillage des moyens de contact, au cas où une personne après avoir fini son intervention s'en va en oubliant d'appuyer sur le bouton UNLOCK de son émetteur.Finally, it is possible to provide an additional transmitter which, by pressing a dedicated button of this transmitter, emits a signal adapted to unlock the locking and unlocking means of the contact means, in the event that a person after having finished his intervention is forgetting to press the UNLOCK button on its transmitter.
La présente invention n'est nullement limitée aux modes de réalisation décrits et représentés, mais l'homme du métier saura y apporter toute variante conforme à son esprit. The present invention is not limited to the embodiments described and shown, but the skilled person will be able to make any variant within his mind.
