Description

La présente invention est relative à la surveillance d'un réseau d'éclairage, et plus particulièrement d'un réseau d'éclairage public.The present invention relates to monitoring a lighting network, and more particularly a public lighting network.

On sait qu'un réseau d'éclairage public est commandé à distance pour l'allumage et l'extinction du système optique de chaque lampadaire. Par ailleurs, un poste de distribution électrique alimente plusieurs circuits d'un même réseau et, sur chaque circuit, les systèmes optiques ou luminaires sont répartis le long de trajets de plusieurs kilomètres chacun.It is known that a public lighting network is remotely controlled for switching on and off the optical system of each lamppost. In addition, an electrical distribution station supplies several circuits of the same network and, on each circuit, the optical or lighting systems are distributed along paths of several kilometers each.

Un poste peut être normalement alimenté et sous tension, ainsi que les différents départs des circuits sur lesquels sont installés les foyers lumineux, alors que ces derniers peuvent être défectueux. Il est donc nécessaire de prévoir à la fois, d'une part une surveillance de nuit par contrôle visuel des milliers de foyers lumineux équipant une ville, et d'autre part une réparation de jour par des équipes spécialisées. Cela entraîne des frais de main-d'oeuvre et des pertes de temps importants.A substation can be normally powered and energized, as can the various outgoing circuits on which the light sources are installed, while the latter may be defective. It is therefore necessary to provide both, on the one hand, night surveillance by visual control of the thousands of light sources equipping a city, and, on the other hand, daytime repair by specialized teams. This results in significant labor costs and wasted time.

La présente invention a pour but d'éviter ces inconvénients, en proposant un dispositif nouveau capable de signaler à un poste de contrôle non seulement l'existence, mais aussi la position ou adresse d'un système optique défectueux, ainsi que l'heure de la panne.The object of the present invention is to avoid these drawbacks by proposing a new device capable of signaling to a checkpoint not only the existence, but also the position or address of a defective optical system, as well as the time of failure.

La présente invention a ainsi pour objet un dispositif de surveillance de l'ensemble des systèmes optiques d'un réseau d'éclairage public, ce dispositif se caractérisant essentiellement en ce qu'il comprend, sur chaque système optique, un capteur de lumière à fibre optique relié à un module électronique individuel, lequel est en liaison électrique avec un module électronique intermédiaire, l'ensemble des modules intermédiaires qui contrôlent l'ensemble du réseau étant connecté au système micro-informatique d'un poste de contrôle.The present invention thus relates to a device for monitoring all the optical systems of a public lighting network, this device being characterized essentially in that it comprises, on each optical system, a fiber light sensor optics connected to an individual electronic module, which is in electrical connection with an intermediate electronic module, the set of intermediate modules which control the entire network being connected to the microcomputer system of a control station.

Un tel dispositif permet de réaliser la surveillance et la localisation de chaque système optique, non pas en surveillant le courant d'alimentation reçu par le système optique, mais en surveillant l'émission ou la non-émission de lumière qui en résulte. Ainsi, c'est le résultat du fonctionnement qu'on observe, ce qui permet d'éliminer tout risque d'erreur ou d'ambiguïté dans les informations gérées par le poste de contrôle central.Such a device makes it possible to carry out the monitoring and localization of each optical system, not by monitoring the supply current received by the optical system, but by monitoring the emission or non-emission of light which results therefrom. Thus, it is the result of the operation that is observed, which eliminates any risk of error or ambiguity in the information managed by the central control station.

Selon un mode de réalisation préférentiel du dispositif selon l'invention, le poste de contrôle central comporte des moyens de programmation de séquences de dialogue avec les modules intermédiaires.According to a preferred embodiment of the device according to the invention, the central control station includes means for programming dialogue sequences with the intermediate modules.

Ces moyens de programmation permettent de fixer la date et l'heure de déclenchement de ces séquences, comportant par exemple une horloge donnant la date et l'heure en permanence, et comportant un moyen de comparaison de ces informations avec des dates et heures chargées par le poste central et conservées en mémoire.These programming means make it possible to fix the date and time of triggering of these sequences, comprising for example a clock giving the date and time permanently, and comprising a means of comparing this information with dates and times loaded by the central station and kept in memory.

Ces moyens de programmation peuvent comporter aussi une mémoire dans laquelle est conservé l'ordre des modules intermédiaires avec lesquels le dialogue est successivement mis en place. Cette mémoire peut être chargée par le poste central.These programming means can also include a memory in which the order of the intermediate modules is kept with which the dialogue is successively set up. This memory can be loaded by the central station.

La séquence de dialogue avec chacun des modules intermédiaires est, selon ce mode de réalisation préférentiel, enclenchée automatiquement à un instant prédéterminé, et selon un ordre prédéterminé, chaque dialogue avec les modules intermédiaires comportant les phases suivantes :

  • émission par le poste central de l'adresse d'un poste intermédiaire et de l'ordre d'interrogation des modules individuels reliés audit poste intermédiaire ;
  • émission par ledit poste intermédiaire, successivement, des adresses des modules individuels, dans l'ordre demandé par le poste central ;
  • décodage par les modules individuels de leur adresse, par l'intermédiaire d'un modulateur-démodulateur, et émission par les modules individuels de l'état allumé ou éteint des foyers auxquels ils sont respectivement liés ;
  • réception par le module intermédiaire des informations d'état provenant des modules individuels et émission de ces informations vers le poste central.
The dialogue sequence with each of the intermediate modules is, according to this preferred embodiment, automatically engaged at a predetermined instant, and in a predetermined order, each dialogue with the intermediate modules comprising the following phases:
  • transmission by the central station of the address of an intermediate station and of the order of interrogation of the individual modules connected to said intermediate station;
  • transmission by said intermediate station, successively, of the addresses of the individual modules, in the order requested by the central station;
  • decoding by their individual modules of their address, by means of a modulator-demodulator, and emission by the individual modules of the on or off state of the homes to which they are respectively linked;
  • reception by the intermediate module of the status information from the individual modules and transmission of this information to the central station.

Le poste central compare ces informations d'état aux informations d'alimentation des foyers et en déduit les anomalies, ou pannes.The central station compares this status information with household supply information and deduces anomalies or breakdowns.

Il est à noter que ces séquences peuvent être incomplètes, certains des modules intermédiaires ou certains des modules individuels pouvant ne pas être interrogés au cours d'une séquence.It should be noted that these sequences may be incomplete, some of the intermediate modules or some of the individual modules not being able to be interrogated during a sequence.

Préférentiellement, le poste central comporte une horloge indiquant la date et l'heure. Il associe, à chaque panne détectée, en plus de son adresse qui lui est transmise par un module individuel détectant cette panne par l'intermédiaire d'un module intermédiaire, la date et l'heure de ladite panne. Ces différentes informations sont mémorisées, imprimées ou affichées par le poste central.Preferably, the central station includes a clock indicating the date and time. It associates, with each detected fault, in addition to its address which is transmitted to it by an individual module detecting this fault via an intermediate module, the date and time of said fault. This various information is stored, printed or displayed by the central station.

Le dessin annexé, donné à titre d'exemple non limitatif, permettra de mieux comprendre les caractéristiques de l'invention et les avantages qu'elle est susceptible de procurer.The appended drawing, given by way of nonlimiting example, will allow a better understanding of the characteristics of the invention and the advantages which it is likely to provide.

Si on se réfère à la figure 1, on voit sur cette figure un poste de contrôle central 1 dont le micro-ordinateur 2 est relié, par une liaison téléphonique 3, à un module intermédiaire 4. Ce dernier est logé dans un poste de transformation ou dans une armoire à basse tension 5 assurant l'alimentation d'une branche 6 d'un réseau d'éclairage public. Cette branche 6 groupe, le long d'une ligne électrique d'alimentation à basse tension 7 (par exemple sous 220/240 volts), divers systèmes optiques ou foyers lumineux, tels que 8, 9, 10, 11, 12. Il peut s'agir de projecteurs de lampadaires ou de foyers lumineux d'un type en lui-même connu.If we refer to Figure 1, we see in this figure a central control station 1 whose microcomputer 2 is connected, by a telephone link 3, to an intermediate module 4. The latter is housed in a transformer station or in a low-voltage cabinet 5 ensuring the supply of a branch 6 of a public lighting network. This branch 6 group, along a low voltage power supply line 7 (for example at 220/240 volts), various optical systems or light sources, such as 8, 9, 10, 11, 12. It can be street lamp spotlights or light sources of a type known per se.

L'invention consiste à équiper chaque foyer lumineux 8 à 12 d'un capteur à fibre optique 13 qui lui fait face pour détecter directement et sur place si le système optique émet ou non de la lumière.The invention consists in equipping each light source 8 to 12 with a fiber optic sensor 13 which faces it to detect directly and on site whether or not the optical system emits light.

Chaque fibre optique 13 est reliée à un module individuel 14, lequel est illustré en figure 3 et comporte :

  • un photo-détecteur 15 qui reçoit de la fibre 13 un signal optique et le transforme en un signal électrique envoyé dans une ligne électrique 16;
  • un micro-contrôleur 17 qui reçoit les signaux de la ligne 16, la tension d'alimentation provenant d'un générateur de tension 18, et les signaux d'une mémoire morte programmée 19, et qui envoie des signaux logiques (bits) dans une ligne 20;
  • une carte de modulation-démodulation 21 assurant l'interface entre les signaux logiques de la ligne 20 et la ligne électrique 7 à basse tension.
Each optical fiber 13 is connected to an individual module 14, which is illustrated in FIG. 3 and includes:
  • a photo-detector 15 which receives an optical signal from the fiber 13 and transforms it into an electrical signal sent in an electrical line 16;
  • a microcontroller 17 which receives the signals from line 16, the supply voltage from a voltage generator 18, and the signals from a programmed read only memory 19, and which sends logic signals (bits) in a line 20;
  • a modulation-demodulation card 21 providing the interface between the logic signals of line 20 and the low voltage power line 7.

Ainsi, chaque système optique 8 à 12 possède individuellement son module individuel 14.Thus, each optical system 8 to 12 individually has its individual module 14.

Le poste de transformation ou armoire à basse tension de chaque branche du réseau d'éclairage public contient le module intermédiaire 4 illustré sur la figure 2. Ce module 4 comporte une interface de communication, ou carte de modulation-démodulation 22, placée entre le module intermédiaire 4 et les divers modules individuels 14 et assurant l'envoi d'adresse, de mots de commande et d'informations concernant l'état, éclairé ou non, du foyer 8 à 12 correspondant.The transformer substation or low-voltage cabinet in each branch of the public lighting network contains the intermediate module 4 illustrated in FIG. 2. This module 4 includes a communication interface, or modulation-demodulation card 22, placed between the module intermediate 4 and the various individual modules 14 and ensuring the sending of address, control words and information concerning the state, lit or not, of the corresponding hearth 8 to 12.

Un micro-contrôleur 23 constitué par un microprocesseur programmé avec base de temps ou "timer" est en permanence relié à une mémoire vive statique 24, qui recueille les informations données par les modules individuels 14. Le micro-contrôleur 23 est alimenté par un générateur de tension 25, et il est relié, ainsi que la carte de modulation-démodulation 22, à un circuit logique 26 qui sert à aiguiller les informations vers les modules individuels 14 ou vers le poste central 1. Finalement, les signaux sont traités dans un "modem" ou système de modulation et démodulation 27 qui traite les informations des circuits logiques (bits) en liaison avec le réseau téléphonique 3. Les informations recueillies sont traitées sur micro-ordinateur au moyen d'un logiciel spécialisé qui est relié ou incorporé au poste central 1 et qui peut comporter des moyens de programmation de séquences de dialogue avec les modules intermédiaires 4.A microcontroller 23 constituted by a microprocessor programmed with time base or "timer" is permanently connected to a static random access memory 24, which collects the information given by the individual modules 14. The microcontroller 23 is supplied by a generator voltage 25, and it is connected, as well as the modulation-demodulation card 22, to a logic circuit 26 which is used to route the information to the individual modules 14 or to the central station 1. Finally, the signals are processed in a "modem" or modulation and demodulation system 27 which processes the information of the logic circuits (bits) in connection with the telephone network 3. The information collected is processed on a microcomputer by means of specialized software which is connected or incorporated into the central station 1 and which may include means for programming dialogue sequences with the intermediate modules 4.

On voit donc qu'en service :

  • chaque module individuel 14 fournit des informations sur l'état de chaque foyer 8 à 12 (allumé ou éteint), et sur l'adresse de chaque foyer défectueux ( éteint, alors qu'il devrait être allumé);
  • chaque module intermédiaire 4 transmet au poste central 1 l'adresse du foyer 8 à 12 jugé défectueux sur son circuit. Ce dernier point est fondamental pour gérer la fiabilité et la longévité du matériel d'éclairage, ce qui, jusqu'à présent, n'était pas contrôlé.
So we see that in service:
  • each individual module 14 provides information on the state of each household 8 to 12 (on or off), and on the address of each defective household (off, when it should be on);
  • each intermediate module 4 transmits to the central station 1 the address of the hearth 8 to 12 deemed defective on its circuit. This last point is fundamental to managing the reliability and longevity of lighting equipment, which until now has not been controlled.

Sur les figures 4, 5 et 6 on a représenté une variante de réalisation, dans laquelle la ligne à basse tension 7 sert uniquement à l'alimentation. Pour transmettre les informations dans un sens et dans l'autre entre les modules-esclaves 14 et le module intermédiaire 4, on a prévu, cette fois, une ligne téléphonique spécialisée 28.In Figures 4, 5 and 6 there is shown an alternative embodiment, in which the low voltage line 7 is used only for power. To transmit the information back and forth between the slave modules 14 and the intermediate module 4, a dedicated telephone line 28 has been provided this time.

Dans le module intermédiaire 4, c'est à la carte de modulation 22 qu'aboutit la ligne spécialisée 28. Cette dernière est, comme précédemment, reliée au circuit logique d'aiguillage 26 qui envoie des "bits" au "modem" 27, lequel émet vers le réseau téléphonique 3, ou en reçoit des signaux.In the intermediate module 4, it is to the modulation card 22 that the dedicated line 28 ends up. The latter is, as before, connected to the logic switching circuit 26 which sends "bits" to the "modem" 27, which transmits to or receives signals from the telephone network 3.

Par ailleurs, seul le générateur de tension 25 est raccordé à la ligne d'alimentation 7.Furthermore, only the voltage generator 25 is connected to the supply line 7.

Comme précédemment indiqué, la variante des figures 4, 5 et 6, permet :

  • de détecter à distance tout foyer lumineux tel que 8, 9, 10, 11, 12 ;
  • d'indiquer son adresse au poste central 1 ;
  • d'indiquer également l'heure et la date auxquelles le défaut a été détecté.
As previously indicated, the variant of Figures 4, 5 and 6 allows:
  • remotely detect any light source such as 8, 9, 10, 11, 12;
  • indicate their address to central station 1;
  • also indicate the time and date on which the fault was detected.
