Description

La présente invention concerne un dispositif de contrôle de trafic par commande de feux de signalisation.The present invention relates to a traffic control device by controlling traffic lights.

Un carrefour contrôlé comprend, traditionnellement, au moins quatre feux tricolores, à chacun desquels sont optionnellement associés une ou plusieurs flèches de tolérance de passage et des feux piétons. Ces différents signaux lumineux sont pilotes, au moins à l'échelon du carrefour, par un contrôleur de trafic comprenant une unité de gestion et de commande de signaux, avantageusement à technologie numérique, commandant les phases d'allumage et d'extinction des différents signaux lumineux en fonction de séquences de temporisation données, éventuellement modulées par des dispositifs de détection de trafic ou par une unité de contrôle centrale. Les contrôleurs de trafic connus, dont on a représenté un bloc diagramme fonctionnel sur la figure 1, comprennent une unité de gestion des informations et de commande de signaux 1 transmettant et recevant, par des lignes 2 et 4, toutes les informations de commande et de contrôle des différents signaux Aij des feux tricolores f; via une série de sous-ensembles si et une batterie 3 de boîtiers de raccordement trois voies reliés au sous-ensemble si par les lignes 4 et aux feux fi par des lignes de puissance 1 n. Dans cet agencement, chaque sous-ensemble si (correspondant à un feu tricolore), est lui-même subdivisé en trois unités triples αi;, βi et γ, chaque unité αi; assurant la commutation électronigue de la tension secteur aux bornes d'une lampe Aij du feu tricolore F; correspondant, chaque unité βi; assurant la synchronisation des signaux de commande du commutateur électronique de αi; sur la tension secteur, et chaque unité y; assurant !a détection et la mise en forme des informations de retour nécessaire au traitement des anomalies de fonctionnement des unités lumineuses Ai. Le bornier répartiteur 3 alimenté par le secteur supporte en outre tous les modules de protection. Cette technologie, lourde et nécessairement redondante, dans laquelle les différents composants 1 à 4 sont en fait regroupés dans le contrôleur C, tient compte du fait que le fabricant de dispositifs de contrôle doit offrir un contrôleur relativement standard, offrant le nombre de sorties nécessaires pour un carrefour donné, malgré l'ignorance dans laquelle il est de l'implantation particulière du carrefour particulier à équiper, notamment en ce qui concerne les signaux lumineux annexes tels que les feux piétons et les flèches de tolérance et de discrimination. Il en résulte une occupation relativement irrationnelle des volumes utilisables et des associations peu souhaitables au niveau de la connexion entre les différentes techniques utilisées, telles que l'électronique de puissance et la microélectronique. De ce fait, en raison de la densité des informations entre l'unité de gestion 1 et le bornier répartiteur 3, et donc de la complexité de la connexion associée 2, 4, il n'est guère possible d'envisager une décentralisation des unités de commande et de contrôle vers les signaux lumineux, ce qui interdit en outre une maintenance rapide des matériels et une optimisation des coûts de production.A controlled intersection traditionally includes at least four traffic lights, to each of which are optionally associated one or more crossing tolerance arrows and pedestrian lights. These different light signals are piloted, at least at the intersection level, by a traffic controller comprising a signal management and control unit, advantageously with digital technology, controlling the switching on and off phases of the different signals. light according to given timing sequences, possibly modulated by traffic detection devices or by a central control unit. The known traffic controllers, a functional block diagram of which has been represented in FIG. 1, comprise an information management and signal control unit 1 transmitting and receiving, by lines 2 and 4, all of the control and control of the various signals A ij of the traffic lights f; via a series of sub-assemblies si and a battery 3 of three-way connection boxes connected to the sub-assembly if by lines 4 and to lights f i by power lines 1 n . In this arrangement, each subset si (corresponding to a traffic light), is itself subdivided into three triple units α i ;, β i and γ, each unit α i ; ensuring the electronic switching of the mains voltage across a lamp A ij of the traffic light F; corresponding, each unit β i ; ensuring the synchronization of the control signals of the electronic switch of α i ; on the mains voltage, and each unit y; ensuring! the detection and the formatting of the return information necessary for the treatment of operating anomalies of the light units A i . The distribution terminal block 3 supplied by the sector also supports all the protection modules. This heavy and necessarily redundant technology, in which the different components 1 to 4 are in fact grouped together in the controller C, takes into account the fact that the manufacturer of control devices must offer a relatively standard controller, offering the number of outputs necessary for a given crossroads, despite the ignorance in which it is of the particular location of the particular crossroads to be equipped, in particular with regard to additional light signals such as pedestrian lights and arrows of tolerance and discrimination. The result is a relatively irrational occupation of usable volumes and undesirable associations in terms of the connection between the different techniques used, such as power electronics and microelectronics. Therefore, due to the density of information between the management unit 1 and the distribution terminal block 3, and therefore the complexity of the associated connection 2, 4, it is hardly possible to envisage a decentralization of the units command and control to the light signals, which also prevents rapid maintenance of equipment and optimization of production costs.

Certains systèmes recents (par exemple FR-A-2 381 075) prévoient la commande de feux de circulation par un organe de puissance associe à un micro-processeur modulaire gérant les différents signaux. Cependant ces systèmes comprennent des modules de puissance et de commutation pour chaque groupe de feux, ce qui ne permet aucune souplesse et adaptabilite au cas particulier.Certain recent systems (for example FR-A-2 381 075) provide for the control of traffic lights by a power unit associated with a modular microprocessor managing the various signals. However, these systems include power and switching modules for each group of lights, which allows no flexibility and adaptability to the particular case.

La présente invention a précisément pour objet de proposer un dispositif de contrôle de trafic à haute intégration, permettant une optimisation de la connexion entre les ensembles de commande et les ensembles commandés, et autorisant une réduction considérable de l'encombrement du dispositif et des coûts, ainsi qu'une augmentation de l'isolement électrique et physique entre l'électronique de commande et les charges commutées, sur la base d'une modularité permettant d'utiliser de façon souple et fiable le nombre de modules de puissance correspondant exactement au nombre de signaux lumineux à commander.The object of the present invention is precisely to propose a highly integrated traffic control device, allowing optimization of the connection between the control assemblies and the controlled assemblies, and allowing a considerable reduction in the size of the device and in costs, as well as an increase in the electrical and physical isolation between the control electronics and the switched loads, on the basis of a modularity allowing flexible and reliable use of the number of power modules corresponding exactly to the number of light signals to be controlled.

Pour ce faire, selon une caractéristique de la présente invention, à chaque signal lumineux effectivement exploité est relié un module de puissance incorporant le moyen de commutation associé. Chaque module de puissance est connecté d'une part directement à un circuit commun d'alimentation de puissance et d'autre part à des bornes déterminées de l'unité de gestion correspondant audit signal lumineux. Chaque module est donc autonome et indépendant.To do this, according to a characteristic of the present invention, a power module incorporating the associated switching means is connected to each light signal actually used. Each power module is connected on the one hand directly to a common power supply circuit and on the other hand to determined terminals of the management unit corresponding to said light signal. Each module is therefore autonomous and independent.

Selon l'invention, dans chaque module de puissance, géométriquement défini et optimisé, sont intégrées les deux fonctions principales constitutives du contrôle de trafic, à savoir la commutation et le contrôle de fonctionnement des feux ou signaux lumineux et la connexion assurant l'alimentation en puissance des signaux lumineux et des circuits de commande associés. La grande souplesse d'utilisation du dispositif selon l'invention, avec ses modules de puissance autonomes et indépendants, permet l'implantation de ces derniers, soit dans le contrôleur de trafic, de façon conventionnelle, soit dans les supports mêmes des feux de signalisation. La séparation marquée entre l'unité de gestion à microprocesseur programmable in situ ou piloté et les modules de puissance permet en autre, à partir, d'éléments standard, de s'adapter simplement et efficacement aux différentes configurations possibles pour un carrefour, en utilisant le strict nombre d'éléments nécessaire en fonction du nombre des signaux lumineux, indépendamment de leur fonction propre dans le carrefour, ainsi qu'optionnellement un pilotage des contrôleurs de différents carrefours par une unité centrale de gestion et de commande via l'unité de gestion périphérique du carrefour.According to the invention, in each geometrically defined and optimized power module, the two main functions constituting traffic control are integrated, namely the switching and operational control of lights or light signals and the connection ensuring the supply of power of light signals and associated control circuits. The great flexibility of use of the device according to the invention, with its autonomous and independent power modules, allows the installation of the latter, either in the traffic controller, in a conventional manner, or in the very supports of the traffic lights. . The marked separation between the management unit with microprocessor programmable in situ or controlled and the power modules also allows, from standard elements, to adapt simply and effectively to the different possible configurations for a crossroads, using the strict number of elements necessary depending on the number of light signals, independently of their proper function in the crossroads, as well as optionally piloting the controllers of different crossroads by a central management and control unit via the peripheral crossroads management unit.

Comme représenté sur les figures 2 à 5, le dispositif de contrôle de trafic selon l'invention comprend une unité de gestion et de commande des signaux 10, à microprocesseur programmable,présentant une série de paires de bornes de sortie b; chacune affectée au contrôle d'un signal lumineux A (de feux tricolores, de flèche ou de signal piéton). Conformément à la présente invention, à chaque signal lumineux A est associé un module de puissance Mi,relie, d'une part, à la paire de bornes correspondante b; de l'unité 10, et d'autre part, à deux paires de lignes bus d'alimentation de puissance 11 et 12. Chaque module de puissance M comprend une carte de circuit imprimé 25 comportant deux paires de broches de connexion 13, 14 aux paires de lignes bus 11 et 12, et une paire 15 de lignes de liaison microcourants pour la connexion à la paire de bornes b; de la carte d'unité de gestion et de commande 10, ainsi qu'une paire de bornes de sortie à serre-fils 16 et 17, pour la connexion à la lampe associée A et une borne de masse 24.As shown in Figures 2 to 5, the traffic control device according to the invention comprises a signal management and control unit 10, with programmable microprocessor, having a series of pairs of output terminals b; each assigned to the control of a light signal A (three-color lights, arrow or pedestrian signal). According to the present invention, each light signal A is associated with a power module M i , connected, on the one hand, to the corresponding pair of terminals b; of the unit 10, and on the other hand, to two pairs of power supply bus lines 11 and 12. Each power module M comprises a printed circuit board 25 comprising two pairs of connection pins 13, 14 to the pairs of bus lines 11 and 12, and a pair 15 of microcurrent connection lines for connection to the pair of terminals b; of the management and control unit card 10, as well as a pair of wire clamp output terminals 16 and 17, for connection to the associated lamp A and a ground terminal 24.

La liaison 15 entre l'unité de gestion 10 et chaque module M, transmet deux informations,à savoir un signal E, généré par l'unité de gestion 10, commandant l'établissement de la tension secteur aux bornes de la lampe A, et un signal S de validation confirmant ou infirmant l'effet du signal E pour le contrôle de la lampe A.Le signal E commande le déclenchement synchrone, c'est-à-dire au passage à zero, du courant secteur d'un commutateur statique 18, comprenant typiquement un TRIAC couplé à un pont de diodes,commandant l'alimentation de la lampe A.L'isolement entre le signal de commande E provenant de l'unité de gestion 10 et le commutateur statique 18 est assuré par un coupleur opto-électronique 19 et son circuit de commande et de polarisation associé 20. Similairement, quoique de façon non limitative, le signal S est transmis vers l'unité de gestion 10 par l'intermédiaire d'un autre coupleur opto-électronique 21 et de son circuit de commande et de polarisation associé 22. Un fusible 23 est avantageusement prévu, dans le module M, entre la lampe A et le commutateur statique 18 pour assurer la protection en courant du circuit commandé de la lampe, une varistance en parallèle 50 assurant la protection du module. Le circuit de la figure 3 est effectué suivant la technique des circuits imprimés sur une carte de module 25.The link 15 between the management unit 10 and each module M transmits two pieces of information, namely a signal E, generated by the management unit 10, controlling the establishment of the mains voltage at the terminals of the lamp A, and a signal S of validation confirming or invalidating the effect of the signal E for the control of the lamp A. The signal E controls the synchronous triggering, that is to say at zero crossing, of the mains current of a static switch 18, typically comprising a TRIAC coupled to a diode bridge, controlling the supply of the lamp A. The isolation between the control signal E coming from the management unit 10 and the static switch 18 is ensured by an opto coupler -electronics 19 and its associated control and bias circuit 20. Similarly, although not limited to, the signal S is transmitted to the management unit 10 via another opto-electronic coupler 21 and its associated control and bias circuit 22. A fuse 2 3 is advantageously provided, in the module M, between the lamp A and the static switch 18 to ensure current protection of the controlled circuit of the lamp, a varistor in parallel 50 ensuring the protection of the module. The circuit of FIG. 3 is carried out according to the technique of printed circuits on a module card 25.

Comme on le voit sur la figure 5, les paires de lignes bus 11 et 12 sont aménagées dans un sous-ensemble bussupport 26, assurant la transmission de puissance du secteur aux modules M, et servant également au support de ces derniers. Comme représenté sur la figure 5, le sous-ensemble bus-support 26 comprend un profilé support 27 en aluminium extrudé définissant deux rainures paralleles et distantes l'une de l'autre 28 et 29, débouchant sur une même face du profilé, ces rainures étant séparées par deux ailes en saillie du profilé définissant, entre elles, une rainure centrale 30 aux parois en regard striées à un pas standard pour recevoir par vissage une extrémité de tige de vis, la rainure 30 débouchant également sur la même face du profilé 27. Dans chacune des rainures 28 et 29 est disposé un profilé de gainage en matériau plastique isolant 31, définissant lui-même deux rainures longitudinales 32 et 33,débouchant dans la gorge d'accès à la rainure associée 28 ou 29 au profilé 28. Dans les rainures 31 et 32 sont disposées des barrettes de connexion incluant les barres bus longitudinales 11 et 12, et des séries de pattes élastiques transversales aux barres pour le contact électrique d'embrochage avec les broches 13 et 14 des modules M.As can be seen in FIG. 5, the pairs of bus lines 11 and 12 are arranged in a bussupport sub-assembly 26, ensuring the transmission of power from the sector to the modules M, and also serving to support the latter. As shown in FIG. 5, the bus-support sub-assembly 26 comprises a support profile 27 made of extruded aluminum defining two parallel and distant grooves 28 and 29, opening onto the same face of the profile, these grooves being separated by two projecting wings from the profile defining, between them, a central groove 30 with facing walls striated at a standard pitch to receive by screwing one end of the screw rod, the groove 30 also opening onto the same face of the profile 27 In each of the grooves 28 and 29 is disposed a sheathing profile of insulating plastic material 31, itself defining two longitudinal grooves 32 and 33, opening into the access groove to the associated groove 28 or 29 to the profile 28. In the grooves 31 and 32 are arranged connection bars including the longitudinal bus bars 11 and 12, and a series of elastic tabs transverse to the bars for the electrical racking contact with the pins 13 and 14 of the M modules.

Selon une caractéristique de l'invention, chaque module M comprend un boîtier 34,en aluminium extrudé de section rectangulaire, définissant un logement interne 35 pour la carte équipée 25 et présentant, à cet effet, au moins une paire de glissières 36 de guidage et de maintien des cartes 25, ainsi que, dans une paroi latérale, un orifice 37 pour le passage d'une vis de fixation de la carte 25, en coopération avec un trou de vis 38 sur une patte rapportée sur la carte 25. Le boîtier 34, servant également de dissipateur thermique pour le TRIAC du commutateur 18, comporte également, dans la cavité interne 35, un canon longitudinal 39 de guidage de la vis de fixation 40 destinée à être vissée dans la rainure striée 30 du profilé 27. Pour permettre un montage assemblé à coulissement côte à côte des différents boîtiers 34, ceux-ci comprennent, sur une paroi latérale, une rainure d'assemblage 41, destinée à recevoir à coulissement une aile d'une rainure complémentaire formant tenon d'assemblage 42 prévue sur l'autre face latérale du boîtier 34. Le module est complété, sur sa face avant, par un capot cache-bornes 43 en matériau plastique isolant, recevant les serres-fils 16 et 17 et comprenant des orifices d'accès 44 à ces derniers, et par un serre-fil 24 de mise à la masse, relié électriquement au corps métallique du boîtier 34. Chaque module M comprend en outre, avantageusement, un voyant de fonctionnement 45 constitué par exemple par une diode électroluminescente, signalant la présence de la tension secteur aux bornes de la lampe associée A. Cet agencement permet donc un montage immédiat des différents modules M par embrochage sur le profilé bus support 26 et sa fixation en place par serrage de la vis de fixation 40, sans nécessiter d'intervention sur les autres modules déjà montés ou à monter.According to a characteristic of the invention, each module M comprises a housing 34, of extruded aluminum of rectangular section, defining an internal housing 35 for the equipped card 25 and having, for this purpose, at least one pair of guide rails 36 and for holding the cards 25, as well as, in a side wall, an orifice 37 for the passage of a card fixing screw 25, in cooperation with a screw hole 38 on a tab attached to the card 25. The housing 34, also serving as a heat sink for the TRIAC of the switch 18, also includes, in the internal cavity 35, a longitudinal barrel 39 for guiding the fixing screw 40 intended to be screwed into the grooved groove 30 of the profile 27. To allow an assembly assembled by sliding side by side of the various housings 34, these comprise, on a side wall, an assembly groove 41, intended to receive with sliding a wing of a complementary groove forming an assembly tenon ge 42 provided on the other side face of the housing 34. The module is completed, on its front face, by a terminal cover cover 43 made of insulating plastic material, receiving the wire clamps 16 and 17 and comprising access orifices 44 to the latter, and by a grounding wire clamp 24, electrically connected to the metal body of the housing 34. Each module M further comprises, advantageously, an operating indicator 45 constituted for example by a light-emitting diode, signaling the presence of the mains voltage at the terminals of the associated lamp A. This arrangement therefore allows immediate mounting of the various modules M by racking in on the support bus profile 26 and fixing it in place by tightening the fixing screw 40, without requiring intervention on the other modules already mounted or to be mounted.
