Description

La présente invention concerne d'une manière générale les clôtures électrique destinées à protéger des lieux quelconques de toute intrusion ou sortie d'un animal ou d'une personne, l'on trouve de telles clôtures autour d'enclos en vue d'empêcher le bétail d'en sortir.The present invention relates generally to electric fences intended to protect any place from any intrusion or exit by an animal or a person, there are such fences around enclosures in order to prevent the cattle get out.

L'effet dissuasif de ces clôtures est dû à l'envoi d'impulsions sous haute tension et d'une énergie assez élevée dans les fils conducteurs formant la clôture.The deterrent effect of these fences is due to the sending of pulses under high voltage and a fairly high energy in the conductive wires forming the fence.

Il est bien entendu de ce fait primordial pour l'utilisateur des ces clôtures d'être informé de tout mauvais fonctionnement de celles-ci.It is of course therefore essential for the user of these fences to be informed of any malfunction thereof.

Il a déjà été proposé des dispositifs permettant la visualisation de l'état de la clôture et/ou le déclenchement d'une alarme en cas de mauvais fonctionnement de celle-ci.Devices have already been proposed allowing the display of the state of the fence and / or the triggering of an alarm in the event of its malfunction.

C'est ainsi que le EP 0 374 055 affiche un état représentatif du degré d'isolement de la clôture à partir de l'analyse des impulsions envoyées dans ladite clôture. Cette analyse est effectuée par un circuit alimenté par l'enroulement secondaire du transformateur générant les impulsions à haute tension et grande énergie.EP 0 374 055 thus displays a state representative of the degree of isolation of the fence from the analysis of the pulses sent into said fence. This analysis is carried out by a circuit supplied by the secondary winding of the transformer generating the high voltage and high energy pulses.

Dans le EP 0 381 585, l'on surveille la présence ou l'absence d'un signal de retour généré par un répondeur situé à l'extrémité de la clôture. L'état de la clôture est déduit par l'analyse de l'intervalle de temps séparant l'envoi de l'impulsion et la réception du signal de retour. Un dépassement de cet intervalle de temps permet de détecter une détérioration de la clôture.In EP 0 381 585, the presence or absence of a return signal generated by an answering machine located at the end of the fence is monitored. The state of the closure is deduced by analyzing the time interval between sending the pulse and receiving the return signal. Exceeding this time interval makes it possible to detect deterioration of the fence.

Chacun de ces dispositifs ne permet l'étude et la mise à la disposition de l'utilisateur que d'une seule caractéristique représentative de l'état de la clôture.Each of these devices only allows the study and the availability to the user of a single characteristic representative of the state of the fence.

Les dispositifs connus à l'heure actuelle sont tous assez volumineux ce qui rend leur installation difficile, de plus ils consomment beaucoup d'énergie.The devices known at present are all quite bulky which makes their installation difficult, moreover they consume a lot of energy.

La présente invention tend alors à proposer un dispositif de faible encombrement et de faible consommation capable de plus de fournir à l'utilisateur un plus grand nombre d'informations.The present invention therefore tends to propose a device of small bulk and low consumption capable of moreover providing the user with a greater number of information.

Ces buts sont atteints en mettant en oeuvre un microcontrôleur programmé permettant de disposer d'un outil de travail puissant et consommant peu dans un faible encombrement.These goals are achieved by implementing a programmed microcontroller making it possible to have a powerful working tool and consuming little in a small footprint.

The invention will be better understood thanks to the description which follows given by way of nonlimiting example with reference to the appended drawings in which:
  • FIG. 1 schematically shows a first embodiment of the invention,
  • FIG. 2 is a partial schematic view of an alternative embodiment of the device of FIG. 1,

  • FIG. 4 illustrates the form in which the information is transmitted to the alarm circuit,
  • Figures 5 to 7 illustrate alternative embodiments of the electrically isolated transmission of information to the alarm circuit.

En se référant tout d'abord à la figure 1, l'on reconnait un circuit classique de clôture électrique dans lequel un boîtier 1 renferme des moyens pour générer des impulsions dans la ligne de clôture 3.Referring first to Figure 1, we recognize a conventional electric fence circuit in which a housing 1 contains means for generating pulses in the closing line 3.

Les moyens générant les impulsions sont constitués d'un circuit 6 de charge d'un condensateur 7, alimenté par une source d'énergie 2, d'un thyristor 8 et d'un transformateur 9.The means generating the pulses consist of a circuit 6 for charging a capacitor 7, supplied by an energy source 2, a thyristor 8 and a transformer 9.

De manière connue en soi, la source d'énergie 2 peut être de différentes formes : réseau public d'alimentation en courant alternatif, batterie, pile, panneau solaire, etc ..., le circuit de charge 6 étant adapté à la source d'énergie 2 mise en oeuvre.In a manner known per se, the energy source 2 can be of different forms: public AC power network, battery, battery, solar panel, etc., the charging circuit 6 being adapted to the source d energy 2 implemented.

La ligne de clôture 3 est reliée à la terre en 4 et peut comporter un répondeur 5 disposé à son extrémité qui est destiné à envoyer au boîtier 1 un signal de retour par l'intermédiaire de la ligne de clôture 3 et de la terre 4.The fence line 3 is connected to the earth at 4 and may include a transponder 5 disposed at its end which is intended to send the housing 1 a return signal via the fence line 3 and the earth 4.

Le circuit de charge 6 assure la charge du condensateur 7 tandis que le thyristor 8 en assure sa décharge périodique dans l'enroulement primaire 10 du transformateur 9.The charging circuit 6 charges the capacitor 7 while the thyristor 8 ensures its periodic discharge in the primary winding 10 of the transformer 9.

Des impulsions à haute tension sont alors émises par l'enroulement secondaire 11 du transformateur 9 dans la ligne de clôture 3, avec retour par la terre 4.High voltage pulses are then emitted by the secondary winding 11 of the transformer 9 in the fence line 3, with return by the ground 4.

Le dispositif de surveillance et de visualisation de l'état de la clôture est globalement constitué d'un système de numérisation 12, d'un dispositif d'affichage 14 et d'un circuit d'alarme 16.The fence monitoring and visualization device is generally made up of a digitization system 12, a display device 14 and an alarm circuit 16.

Suivant l'invention, le système de numérisation est un circuit de numérisation 12 intégré électronique microprogrammé du type microprocesseur ou microcontrôleur. Ce circuit exécute, à partir du logiciel qu'il renferme, de nombreuses tâches d'analyse. Il est ainsi capable d'analyser à la demande de l'utilisateur, l'état de la ligne de clôture 3, son degré d'isolement, le fonctionnement du boîtier 1 et/ou de délivrer un autodiagnostic. Ces analyses sont faites à partir des données relatives aux impulsions envoyées dans la ligne de clôture et/ou des données relatives aux impulsions de retour envoyées par un répondeur 5 dans le cas où un tel répondeur est prévu dans la ligne de clôture, ces données étant amenées au circuit de numérisation 12 par la ligne 13 le reliant à la ligne de clôture 3 et à la terre.According to the invention, the digitization system is a microprogrammed electronic microprocessor or microcontroller integrated digitalization circuit 12. This circuit performs, from the software it contains, many analysis tasks. It is thus capable of analyzing, at the user's request, the state of fence line 3, its degree of isolation, the operation of the housing 1 and / or to deliver a self-diagnosis. These analyzes are carried out on the basis of the data relating to the pulses sent in the closing line and / or the data relating to the return pulses sent by an answering machine 5 in the case where such an answering machine is provided in the closing line, these data being brought to the digitization circuit 12 by the line 13 connecting it to the fence line 3 and to the ground.

Ce circuit de numérisation est alimenté en énergie par une ligne 21 le raccordant à un enroulement secondaire annexe 20 du transformateur 9.This digitization circuit is supplied with energy by a line 21 connecting it to an annex secondary winding 20 of the transformer 9.

Cette alimentation du circuit de numérisation 12 sur la source d'énergie destinée aux impulsions de dissuasion sans risque de perturber le fonctionnement de la ligne de clôture est rendue possible par la mise en oeuvre de circuits intégrés programmés nécessitant peu d'énergie pour leur fonctionnement.This supply of the digitization circuit 12 on the energy source intended for deterrence pulses without risk of disturbing the operation of the fence line is made possible by the implementation of programmed integrated circuits requiring little energy for their operation.

Après avoir analysé les différents paramètres demandés, le circuit de numérisation 12 envoie les résultats de ces analyses sur un dispositif d'affichage 14 de tout type désiré par le bus 15.After having analyzed the various parameters requested, the digitization circuit 12 sends the results of these analyzes to a display device 14 of any type desired by the bus 15.

Le dispositif d'affichage 14 ne nécessite lui aussi que peu d'énergie pour fonctionner ce qui permet avantageusement de l'alimenter à partir du secondaire annexe 20 par l'intermédiaire du circuit de numérisation 12.The display device 14 also requires very little energy to operate, which advantageously makes it possible to supply it from the secondary annex 20 via the digitization circuit 12.

Le bus 15 assure donc la transmission des informations en même temps que l'alimentation électrique dudit dispositif d'affichage 14.The bus 15 therefore ensures the transmission of information at the same time as the electrical supply of said display device 14.

Le circuit de numérisation 12 est également relié par une voie 17 de transmission de données au circuit d'alarme 16 afin de prévenir de manière efficace l'utilisateur en cas de fonctionnement anormal de la clôture électrique.The digitization circuit 12 is also connected by a data transmission channel 17 to the alarm circuit 16 in order to effectively warn the user in the event of abnormal operation of the electric fence.

Ce circuit d'alarme 16 est relié à un dispositif sonore ou lumineux 19.This alarm circuit 16 is connected to a sound or light device 19.

Ce dispositif sonore ou lumineux 19 nécessite pour son fonctionnement une grande quantité d'énergie si l'on veut qu'il soit effectivement capable d'alerter l'utilisateur. Il n'est donc pas possible de l'alimenter à partir du transformateur 9 à travers le circuit de numérisation 12 comme cela a été décrit plus haut pour le dispositif d'affichage 14. C'est pourquoi une ligne 36 est disposée entre le circuit d'alarme 16 et la source d'énergie 2 en un point de celle-ci disposé en amont du circuit de charge 6. Afin d'isoler électriquement le circuit de numérisation 12 du circuit d'alarme 16, la voie 17 de transmission de données comporte une isolation électrique 18.This sound or light device 19 requires a large amount of energy for its operation if it is to be effectively capable of alerting the user. It is therefore not possible to supply it from the transformer 9 through the digitization circuit 12 as described above for the display device 14. This is why a line 36 is disposed between the circuit alarm 16 and the power source 2 at a point thereof disposed upstream of the charging circuit 6. In order to electrically isolate the digitization circuit 12 from the alarm circuit 16, the transmission channel 17 of data includes electrical insulation 18.

Dans la variante de réalisation d'une partie du dispositif représentée à la figure 2 l'enroulement secondaire 11 et l'enroulement secondaire annexe 20 du transformateur sont électriquement séparés l'un de l'autre. Le circuit de numérisation 12 est alors alimenté par une ligne 31 électriquement reliée audit secondaire annexe 20 du transformateur. Le circuit de numérisation reçoit alors d'une part l'énergie nécessaire à son fonctionnement par la ligne 31, et d'autre part les données relatives aux impulsions envoyées dans la ligne de clôture 3 par la ligne 13. Ledit circuit de numérisation reste toutefois alimenté à partir de l'énergie délivrée aux impulsions.In the variant embodiment of a part of the device shown in FIG. 2, the secondary winding 11 and the secondary secondary winding 20 of the transformer are electrically separated from one another. The digitization circuit 12 is then supplied by a line 31 electrically connected to said secondary annex 20 of the transformer. The digitization circuit then receives on the one hand the energy necessary for its operation by the line 31, and on the other hand the data relating to the pulses sent in the closing line 3 by the line 13. Said digitization circuit remains however powered from the energy delivered to the pulses.

La figure 3 montre une variante de réalisation d'une autre partie du dispositif de la figure 1. Cette variante concerne le circuit d'alarme.Figure 3 shows an alternative embodiment of another part of the device of Figure 1. This alternative relates to the alarm circuit.

Dans cette réalisation, le circuit d'alarme 16 et le dispositif d'alarme 19 sont situés à l'extérieur du boîtier 1 ce qui permet de les disposer en des lieux plus ou moins éloignés de la clôture électrique dans lesquels l'utilisateur percevra plus sûrement l'alarme.In this embodiment, the alarm circuit 16 and the alarm device 19 are located outside of the box 1 which allows them to be placed in places more or less distant from the electric fence in which the user will perceive more surely the alarm.

La voie 17 de transmission de données doit alors traverser la paroi 22 du boîtier 1, l'isolation électrique 18 étant bien entendu pour des raisons élémentaires de sécurité disposée au niveau de cette paroi 22 afin d'éliminer tout risque de choc électrique.The data transmission channel 17 must then pass through the wall 22 of the housing 1, the electrical insulation 18 of course being for elementary security reasons placed at the level of this wall 22 in order to eliminate any risk of electric shock.

La figure 4 permet de visualiser les informations reçues par le circuit d'alarme 16. Le graphe supérieur représente les impulsions Ims envoyées dans la clôture électrique tandis que le graphe inférieur représente les impulsions Info reçues par ledit circuit d'alarme 16 après le traitement des données effectué dans le circuit de numérisation 12.FIG. 4 makes it possible to view the information received by the alarm circuit 16. The upper graph represents the Ims pulses sent into the electric fence while the lower graph represents the Info pulses received by said alarm circuit 16 after the processing of the data carried out in the digitization circuit 12.

Lorsque l'impulsion envoyée dans la clôture électrique a un niveau normal comme représenté en t1 et t2, le circuit d'alarme 16 reçoit une impulsion d'une durée inférieure à 1ms synchronisée avec l'impulsion envoyée dans la ligne de clôture tandis que lorsque l'impulsion envoyée dans la clôture a un niveau anormalement bas, comme représenté au temps t3, le circuit d'alarme 16 ne reçoit pas d'impulsion ce qui signifie pour lui le déclenchement d'une alarme prévenant l'utilisateur d'un défaut de fonctionnement du dispositif.When the pulse sent in the electric fence has a normal level as shown in t1 and t2, the alarm circuit 16 receives a pulse of duration less than 1 ms synchronized with the pulse sent in the fence line while when the pulse sent in the enclosure at an abnormally low level, as shown at time t3, the alarm circuit 16 does not receive a pulse which means for him the triggering of an alarm warning the user of a fault of the device.

Ce circuit d'alarme 16 permet non seulement de prévenir d'un mauvais fonctionnement de la clôture mais également du mauvais fonctionnement du circuit de numérisation 12, de la voie 17 de transmission de données ou du circuit d'alimentation 21 ou 31.This alarm circuit 16 makes it possible not only to prevent a malfunction of the fence but also the malfunction of the digitization circuit 12, of the data transmission channel 17 or of the supply circuit 21 or 31.

L'utilisateur alerté par le circuit d'alarme 16 peut alors, en prenant connaissance des informations disponibles sur le dispositif d'affichage 14, interpréter le dysfonctionnement de sa clôture.The user alerted by the alarm circuit 16 can then, taking cognizance of the information available on the display device 14, interpret the malfunction of its closure.

Les figures 5 à 7 montrent des exemples de réalisation de la voie 17 de transmission de données pouvant être envisagés.FIGS. 5 to 7 show exemplary embodiments of the data transmission channel 17 that can be envisaged.

A la figure 5, le circuit de numérisation 12 comporte au moins une plaque de circuit imprimé 23 portant un émetteur 25 tandis que le circuit d'alarme comporte une plaque de circuit imprimé 24 portant un récepteur 26.In FIG. 5, the digitizing circuit 12 comprises at least one printed circuit plate 23 carrying a transmitter 25 while the alarm circuit comprises a printed circuit plate 24 carrying a receiver 26.

L'émetteur 25 et le récepteur 26 sont alignés afin que les informations émises à partir du circuit de numérisation 12 soient reçues par le circuit d'alarme 16.The transmitter 25 and the receiver 26 are aligned so that the information transmitted from the digitization circuit 12 is received by the alarm circuit 16.

Lesdits émetteur et récepteur sont éloignés d'une distance assez importante pour assurer l'isolation électrique 18 recherchée. Cette distance sera au minimum de 4 centimètres pour assurer un isolement de l'ordre de 10 kV.Said transmitter and receiver are far enough apart to provide the desired electrical insulation 18. This distance will be at least 4 centimeters to ensure isolation of the order of 10 kV.

Lesdits émetteur et récepteur peuvent être de tout type désiré, par exemple des composants optoélectroniques à radiation infra-rouge ou des composants fonctionnant avec des ondes ultra-sonores.Said transmitter and receiver can be of any desired type, for example optoelectronic components with infrared radiation or components operating with ultrasonic waves.

Dans le mode de réalisation représenté à la figure 6, la voie 17 de transmission de données est constituée par un transformateur dont l'enroulement primaire reçoit les informations du circuit de numérisation 12 et les transmet à l'enroulement secondaire relié au circuit d'alarme 16. L'isolement électrique 18 est celui existant entre les enroulements primaire et secondaire du transformateur.In the embodiment shown in FIG. 6, the data transmission channel 17 is constituted by a transformer, the primary winding of which receives the information from the digitization circuit 12 and transmits it to the secondary winding connected to the alarm circuit 16. The electrical insulation 18 is that existing between the primary and secondary windings of the transformer.

La variante de réalisation représentée à la figure 7 utilise une fibre optique 30 reliant un émetteur 28 porté par une plaque de circuit imprimé 23 du circuit de numérisation 12 à un récepteur 29 porté par une plaque de circuit imprimé 24 du circuit d'alarme 16. Cette fibre optique peut bien entendu traverser la paroi 22 du boîtier 1.The variant embodiment shown in FIG. 7 uses an optical fiber 30 connecting a transmitter 28 carried by a printed circuit board 23 of the digitization circuit 12 to a receiver 29 carried by a printed circuit plate 24 of the alarm circuit 16. This optical fiber can of course pass through the wall 22 of the housing 1.

Cette réalisation présente l'avantage de permettre le positionnement du circuit d'alarme en tout lieu voulu même à distance du boîtier 1 en utilisant une fibre optique de grande longueur. De plus, dans cette variante de réalisation, il n'est pas nécessaire que le récepteur soit strictement positionné en alignement avec l'émetteur.This embodiment has the advantage of allowing the positioning of the alarm circuit in any desired location even at a distance from the housing 1 by using a very long optical fiber.
