Description

La présente invention concerne un procédé et un système de surveillance des défaillances d'au moins une source de rayonnement lumineux, plud particulièrement adaptés à la surveillance d'une pluralité de sources d'éclairage public.The present invention relates to a method and a system for monitoring the failures of at least one light radiation source, plud particularly suitable for monitoring a plurality of public lighting sources.

La surveillance de tels réseaux s'effectue actuellement soit de nuit, ce qui constitue un inconvénient pour le personnel chargé de cette surveillance, soit de jour en maintenant le réseau sous tension, ce qui provoque une dépense d'énergie supplémentaire.Monitoring of such networks is currently carried out either at night, which constitutes a drawback for the personnel responsible for this monitoring, or during the day by keeping the network energized, which causes additional energy expenditure.

Il s'agit de toute manière d'une opération onéreuse qui ne peut pas être réalisée tous les jours.In any case, it is an expensive operation which cannot be carried out every day.

La présente invention vise à pallier ces inconvénients.The present invention aims to overcome these drawbacks.

A cet effet, l'invention a tout d'abord pour objet un procédé de surveillance des défaillances d'au moins une source de rayonnement lumineux, caractérisé par le fait que l'on détecte à l'aide d'un photocomposant le rayonnement éventuellement émis par ladite source pendant une période où elle est sous tension, que l'on émet sur la ligne d'alimentation de la source, en l'absence de rayonnement détecté, un signal de défaillance, et que l'on capte ledit signal de défaillance en un point de la ligne éloigné de ladite source.To this end, the invention firstly relates to a method for monitoring the failures of at least one source of light radiation, characterized in that it is detected using a photocomponent, possibly the radiation emitted by said source during a period when it is energized, which is emitted on the source supply line, in the absence of detected radiation, a failure signal, and that said signal is detected. failure at a point on the line distant from said source.

La surveillance peut ainsi être effectuée en temps réel pendant l'utilisation du réseau, et à distance, ce qui constitue un premier avantage.Monitoring can thus be carried out in real time during network use, and remotely, which is a first advantage.

En outre, les réseaux d'éclairage public modernes sont généralement constitués par des ampoules à des charges lumineuses alimentées par des ballasts, de sorte que, dans certains cas, une ampoule éteinte continue à absorber un courant non négligeable. L'invention permet donc de lever cette difficulté, liée à la détection par constatation de l'absence de courant absorbé.In addition, modern public lighting networks are generally constituted by bulbs with light charges supplied by ballasts, so that, in certain cases, an extinguished bulb continues to absorb a non-negligible current. The invention therefore makes it possible to overcome this difficulty, linked to the detection by observation of the absence of absorbed current.

Dans un mode de réalisation de l'invention appliqué à une pluralité de sources, le signal de défaillance est émis après la mise sous tension des sources, au bout d'un temps fonction d'un numéro d'ordre de la source défaillante dans cette pluralité de sources.In an embodiment of the invention applied to a plurality of sources, the failure signal is emitted after the sources are energized, after a time as a function of a serial number of the faulty source in this plurality of sources.

A titre d'exemple, cette fonction peut être une relation linéaire.As an example, this function can be a linear relation.

Dans ce cas, après la mise sous tensions des sources, on commence par attendre un temps suffisant pour permettre à toutes les sources non défaillantes de s'amorcer et d'être allumées.In this case, after the sources are energized, one begins by waiting for a sufficient time to allow all of the non-failing sources to start up and be switched on.

On émet ensuite, pour chaque source défaillante, un signal sur la ligne d'alimentation, le signal correspondant à une source particulière étant émis après un temps supplémentaire égal au produit d'un temps élémentaire par le numéro d'ordre de la source considérée.Then, for each faulty source, a signal is transmitted on the supply line, the signal corresponding to a particular source being transmitted after an additional time equal to the product of an elementary time by the serial number of the source considered.

On capte par conséquent sur la ligne d'alimentation un nobmre de signaux égal au nombre de sources défaillantes, et l'on peut déduire les numéros d'ordre de ces sources défaillantes de l'instant auquel sont captés ces différents signaux.Consequently, a number of signals equal to the number of faulty sources is picked up on the supply line, and the sequence numbers of these faulty sources can be deduced from the instant at which these different signals are picked up.

Dans un autre mode de mise en oeuvre de l'invention, appliqué également à une pluralité de sources, le signal de défaillance est émis après la détection de la défaillance d'une des sources, pendant un temps fonction d'un numéro d'ordre de cette source dans la pluralité de sources.In another embodiment of the invention, also applied to a plurality of sources, the failure signal is emitted after the detection of the failure of one of the sources, for a time as a function of a serial number of this source in the plurality of sources.

Contrairement à ce qui était le cas ci-dessus, où l'on détectait les sources déjà défaillantes lors de la mise sous tension des sources, ou détecte maintenant les défaillances se produisant en cours de fonctionnement.Contrary to what was the case above, where one detected the sources already failing when the sources were energized, or now detects failures occurring during operation.

Le temps pendant lequel est émis le signal de défaillance correspondant à une source donnée est par exemple proportionnel au numéro d'ordre de cette source, de sorte qu'il suffit, lorsque l'on capte un signal de défaillance sur la ligne d'alimentation, de mesurer la durée de ce signal pour en déduire le numéro d'ordre de la source correspondante.The time during which the failure signal corresponding to a given source is emitted is for example proportional to the serial number of this source, so that it is sufficient, when a failure signal is detected on the supply line , measure the duration of this signal to deduce the serial number of the corresponding source.

Bien entendu, les deux modes de mise en oeuvre décrits ci-dessus peuvent être combinés, le premier mode étant utilisé lors de la mise sous tension du réseau afin de détecter toutes les sources déjà défaillantes à cet instant, puis une commutation s'effectuant pour passer dans le second mode afin de détecter les nouvelles défaillances en temps réel.Of course, the two modes of implementation described above can be combined, the first mode being used during powering up of the network in order to detect all the sources already failing at this instant, then a switching taking place for switch to the second mode in order to detect new failures in real time.

Du fait que l'identification d'une source défaillante s'effectue soit à partir de l'instant d'arrivée du signal correspondant, soit à partir de la durée de ce signal, on peut utiliser très simplement comme signal de défaillance un signal monofréquence, par exemple de fréquence musicale.Since the identification of a faulty source is carried out either from the time of arrival of the corresponding signal, or from the duration of this signal, it is very simple to use as a failure signal a monofrequency signal , for example of musical frequency.

Un tel signal peut être beaucoup plus facilement superposé au courant d'alimentation des sources qu'un signal codé numérique. Il peut en outre être produit par des moyens beaucoup plus simples qu'un tel signal numérique. Enfin, sa détection sur la ligne d'alimentation ne présente aucune difficulté puisqu'un simple filtre unique permet de détecter l'ensemble des signaux correspondant à toutes les sources du réseau.Such a signal can be much more easily superimposed on the supply current of the sources than a digital coded signal. It can also be produced by much simpler means than such a digital signal. Finally, its detection on the supply line presents no difficulty since a simple single filter makes it possible to detect all of the signals corresponding to all the sources of the network.

Dans un mode de réalisation particulier de l'invention, on capte le signal de défaillance à l'aide d'un automate qui transmet ce signal sur une ligne téléphonique, par exemple jusqu'à un poste de contrôle.In a particular embodiment of the invention, the failure signal is captured using an automaton which transmits this signal over a telephone line, for example to a control station.

La présente invention a également pour objet un système de surveillance des défaillance d'au moins une source de rayonnement lumineux, caractérisé par le fait qu'il comprend un photocomposant disposé pour fournir un signal électrique lorsque ladite source émet un rayonnement, des moyens d'émission susceptibles d'émettre un signal de défaillance, sur la ligne d'alimentation de ladite source, et des moyens de commande pour commander les moyens d'émission dans le cas où aucun signal électrique n'est fournir par ledit photocomposant.The present invention also relates to a system for monitoring the failure of at least one source of light radiation, characterized in that it comprises a photocomponent arranged to supply an electrical signal when said source emits radiation, means for emission likely to emit a fault signal, on the supply line for said source, and control means for controlling the transmission means in the event that no electrical signal is supplied by said photocomponent.

Avantageusement, ce photocomposant est relié à la source de rayonnement par une fibre optique.Advantageously, this photocomponent is connected to the radiation source by an optical fiber.

Dans le cas où la source est constituée par l'ampoule d'un candélabre d'éclairage public, il est ainsi possible de grouper l'ensemble du système décrit ci-dessus à la base du candélabre où, d'une part, il est facile d'accès, et où d'autre part, peut être aisément protégé des intempéries et, surtout, des parasites engendrés par la source lumineuse.In the case where the source is constituted by the bulb of a street lighting candelabra, it is thus possible to group the whole of the system described above at the base of the candelabra where, on the one hand, it is easy to access, and where on the other hand, can be easily protected from bad weather and, above all, from parasites generated by the light source.

Les moyens d'émission peuvent, dans un mode de réalisation particulier de l'invention, comprendre un oscillateur, notamment de fréquence musicale.The transmission means may, in a particular embodiment of the invention, comprise an oscillator, in particular of musical frequency.

Dans le cas d'un tel système adapté à la surveillance des défaillances d'une pluralité de source, les moyens de commande peuvent être reliés au moyen d'émission par l'intermédiaire de moyens de temporisation, et agencés pour provoquer l'émission du signal de défaillance au bout d'un temps après un instant prédéterminé, tel que l'instant de la mise sous tension des sources, et/ou pendant un temps après la détection de la défaillance d'une des sources, qui sont fonction d'un numéro d'ordre de la source défaillante dans ladite pluralité de sources.In the case of such a system suitable for monitoring the failures of a plurality of sources, the control means can be connected to the transmission means by means of timing means, and arranged to cause the transmission of the failure signal after a time after a predetermined time, such as when the sources are energized, and / or for a time after detection of the failure of one of the sources, which are a function of a serial number of the faulty source in said plurality of sources.

Ces deux modes de réalisation, qui peuvent d'ailleurs être combinés dans le même système, correspondent aux deux modes de mise en oeuvre du procédé tels qu'ils ont été décrits ci-dessus.These two embodiments, which can moreover be combined in the same system, correspond to the two embodiments of the method as they have been described above.

Le système selon l'invention peut également comprendre un automate en un point de la ligne d'alimentation éloigné de ladite source, agencé pour capter le signal de défaillance et le transmettre sur une ligne téléphonique.The system according to the invention can also include an automaton at a point on the supply line remote from said source, arranged to pick up the fault signal and transmit it over a telephone line.

On décrira maintenant à titre d'exemple non limitatif un mode de réalisation particulier de l'invention en référence aux dessins schématiques annexés dans lesquels :

  • - la figure 1 est une vue d'un candélabre d'éclairage public sur lequel est mis en oeuvre l'invention,
  • - la figure 2 est un schéma électrique d'un dispositif selon l'invention équipant le candélabre de la figure 1 et,
  • - la figure 3 est un schéma électrique d'un dispositif selon l'invention équipant le poste d'alimentation d'un réseau d'éclairage public.
A particular embodiment of the invention will now be described by way of nonlimiting example with reference to the appended schematic drawings in which:
  • FIG. 1 is a view of a street lighting candelabrum on which the invention is implemented,
  • FIG. 2 is an electrical diagram of a device according to the invention fitted to the candelabra of FIG. 1 and,
  • - Figure 3 is an electrical diagram of a device according to the invention fitted to the supply station of a public lighting network.

Le candélabre de la figure 1 comporte une optique 1 dans laquelle est montée une ampoule 2, par exemple à décharges lumineuses, et un support tubulaire 3.The candelabra of FIG. 1 comprises an optic 1 in which is mounted a bulb 2, for example with light discharges, and a tubular support 3.

Une fibre optique 4 est disposée dans le support 3 avec une de ses extrémités dans l'optique 1 au voisinage de l'ampoule 2 et son autre extrémité conectée à un boîtier électrique 5 qui sera décrit en référence à la figure 2.An optical fiber 4 is arranged in the support 3 with one of its ends in the optical 1 in the vicinity of the bulb 2 and its other end connected to an electrical box 5 which will be described with reference to FIG. 2.

Une ligne d'alimentation 6 permet d'une part l'alimentation électrique de l'ampoule 2 et de boîtier 5, et d'autre part, la transmission d'un signal de défaillance lorsque l'ampoule 2 est sous tension mais non allumée.A power line 6 allows on the one hand the electrical supply of the bulb 2 and of housing 5, and on the other hand, the transmission of a fault signal when the bulb 2 is energized but not lit .

La figure 2 montre en 7 la dérivation de la ligne 6 permettant l'alimentation de l'ampoule 2 par l'intermédiaire d'un câble 8, et du boîtier 5 par l'intermédiaire d'une alimentation stabilisée 9.FIG. 2 shows in 7 the derivation of the line 6 allowing the supply of the bulb 2 via a cable 8, and of the housing 5 via a stabilized supply 9.

Un photocomposant 10, par exemple une photodiode, est disposé à l'extrémité inférieure de la fibre optique 4, et son courant de sortie est amplifié dans un amplificateur 11.A photocomponent 10, for example a photodiode, is placed at the lower end of the optical fiber 4, and its output current is amplified in an amplifier 11.

La tension de sortie de l'amplificateur 11, qui est par conséquent représentative de l'état allumé ou éteint de l'ampoule 2, est appliquée à un circuit de temporisation 12 commandé par une unité logique de commande 13 comme cela sera décrit ci-après, de manière à commander à son tour un oscillateur 14 de fréquence musicale.The output voltage of the amplifier 11, which is therefore representative of the on or off state of the bulb 2, is applied to a timing circuit 12 controlled by a logic control unit 13 as will be described below. afterwards, so as to control in turn an oscillator 14 of musical frequency.

La sortie de cet oscillateur, par exemple à quelques centaines de Hz, est appliquée sur la dérivation 7 par l'intermédiaire d'un filtre 15 de manière à être ensuite transmise sur la ligne 6.The output of this oscillator, for example at a few hundred Hz, is applied to the branch 7 via a filter 15 so as to then be transmitted on line 6.

A partir de la mise sous tension de la ligne 6, chaque logique 13 des différents candélabres connectés sur la ligne bloque le dispositif pendant un temps T1 suffisant pour permettre l'amorçage et l'allumage de toutes les ampoules 2 non défaillantes connectées à la ligne 6.As soon as line 6 is energized, each logic 13 of the different candelabras connected to the line blocks the device for a time T1 sufficient to allow the ignition and ignition of all non-faulty bulbs 2 connected to the line 6.

Le temps T1 peut par exemple être de l'ordre de 120 secondes.The time T1 can for example be of the order of 120 seconds.

A l'expiration de ce temps T1, l'unité logique 13 continue à bloquer le dispositif pendant un temps T2, proportionnel par exemple au numéro d'ordre du candélabre par rapport à l'origine de la ligne 6.At the end of this time T1, the logic unit 13 continues to block the device for a time T2, proportional for example to the serial number of the candelabrum relative to the origin of the line 6.

Si, à l'expiration de ce temps T2, aucun signal n'est reçu par la photodiode 6 indiquant que l'ampoule 2 est allumée, l'unité logique 13 provoque l'émission par l'oscillateur 14 d'un signal de défaillance, d'une durée brève mais suffisante pour que le signal qui sera reçu sur la ligne 6 soit bien indentifiable, sans pour autant que deux signaux correspondant à des candélabres contigus risquent de se superposer.If, at the expiration of this time T2, no signal is received by the photodiode 6 indicating that the bulb 2 is on, the logic unit 13 causes the emission by the oscillator 14 of a failure signal , of a short duration but sufficient for the signal which will be received on line 6 to be clearly identifiable, without, however, that two signals corresponding to contiguous candelabra may overlap.

A titre d'exemple, le temps T2 peut être choisi égal à 0,4 x N secondes, où N est le numéro d'ordre du candélabre, tandis que le signal de défaillance est émis pendant une durée de 0,2 seconde.By way of example, the time T2 can be chosen equal to 0.4 × N seconds, where N is the serial number of the candelabrum, while the failure signal is emitted for a duration of 0.2 seconds.

Si par conséquent un signal de défaillance est capté sur la ligne 6 au bout d'un temps T après la mise sous tension de la ligne, le numéro du candélabre défaillant est immédiatement déduit, dans le cas de l'exemple ci-dessus, de la relation :
T = 120 + 0,4 x N
If consequently a failure signal is picked up on line 6 after a time T after the line is energized, the number of the defective candelabra is immediately deduced, in the case of the example above, from the relationship :
T = 120 + 0.4 x N

Dans le cas où le réseau porte par exemple 200 candélabres, on pourra savoir dans le poste d'éclairage public décrit ci-après, au bout d'un temps égal à 120 + 0,4 x 200 = 200 secondes, si des ampoules ne se sont pas allumées et lesquelles.In the case where the network carries for example 200 candelabras, one will be able to know in the public lighting station described below, after a time equal to 120 + 0.4 x 200 = 200 seconds, if bulbs do not did not light up and which ones.

A partir de cet instant, les unités logiques 13 provoquent le basculement du système de temporisation dans un deuxième mode de fonctionnement, permettant de détecter les défaillances se produisant en cours de service.From this moment, the logic units 13 cause the timing system to switch to a second operating mode, making it possible to detect faults occurring during service.

Dès cet instant, la disparition du signal issu de la photodiode 10 déclenche, par l'intermédiaire de la temporisation 12, l'émission par l'oscillateur 14 d'un signal d'une durée Tʹ proportionelle au numéro d'ordre du candélabre.From this moment, the disappearance of the signal from the photodiode 10 triggers, via the time delay 12, the emission by the oscillator 14 of a signal of duration T durée proportional to the serial number of the candelabrum.

A titre d'exemple, on peut choisir Tʹ = 0,2 x N secondes.As an example, we can choose Tʹ = 0.2 x N seconds.

Par conséquent, dans ce deuxième mode de fonctionnement, on peut déduire, à la réception sur la ligne 6 d'un signal de défaillance, l'emplacement de candélabre défaillant à partir de la durée du signal reçu.Consequently, in this second operating mode, it is possible to deduce, on reception on line 6 of a fault signal, the location of the faulty candelabra from the duration of the signal received.

On notera que la probabilité est très faible que deux sources défaillent pratiquement en même temps de sorte que les signaux correspondant se chevauchent.It will be noted that the probability is very low that two sources fail at practically the same time so that the corresponding signals overlap.

De toute manière, il est rare, dans le cas d'un réseau d'éclairage public, d'avoir à intervenir la nuit même, de sorte qu'il suffit, en cas d'ambiguité, de remettre le réseau sous tension pendant quelques minutes le lendemain matin pour localiser avec certitude les sources défaillantes.In any case, it is rare, in the case of a public lighting network, to have to intervene the same night, so that it is sufficient, in case of ambiguity, to turn the network back on for a few minutes the next morning to locate the failing sources with certainty.

La figure 3 représente le dispositif installé au poste d'éclairage public et chargé de détecter, d'analyser et de transmettre les signaux de défaillance.FIG. 3 represents the device installed at the public lighting station and responsible for detecting, analyzing and transmitting the failure signals.

Une pluralité de lignes d'alimentation 6, 6ʹ, ....6ʺ aboutissent à ce poste.A plurality of supply lines 6, 6ʹ, .... 6ʺ lead to this station.

Les tensions sur ces lignes sont filtrées à l'aide de filtres 16, 16ʹ,....16ʺ de manière à détecter les signaux de défaillance en fréquence musicale émis sur les lignes d'alimentation par les différents dispositifs de détection de défaillance tels que 5.The voltages on these lines are filtered using filters 16, 16ʹ, .... 16ʺ so as to detect the failure signals in musical frequency emitted on the supply lines by the various failure detection devices such as 5.

Les signaux ainsi détectés sont redressés en 17, 17ʹ,....17ʺ et amplifiés en 18, 18ʹ,....18ʺ.The signals thus detected are rectified in 17, 17ʹ, .... 17ʺ and amplified in 18, 18ʹ, .... 18ʺ.

Les signaux de défaillance ainsi détectés et traités sont ensuite analysés par un automate programmable 19 qui détermine les sources défaillantes et retransmet les informations recueillies sur un réseau d'alerte 20, par exemple le réseau téléphonique commuté, vers un poste de surveillance.The fault signals thus detected and processed are then analyzed by a programmable controller 19 which determines the faulty sources and retransmits the information collected on an alert network 20, for example the switched telephone network, to a monitoring station.
