Chaque cube 8 présente quatre faces d'affichage _F de couleurs différentes, dont l'une des faces est positionnée dans un plan d' affichage _P s'établissant sensiblement en retrait des bords des côtés 4 (fig. 3). Un élément de visualisation 7, convenant particulièrement bien pour L'invention, a été décrit dans le brevet US 4 558 267. Selon ce brevet, chaque cube comporte, intérieurement, un organe moteur présentant quatre enroulements statoriques montés en relation d'un rotor équipé d'un aimant et calé en rotation sur le cube. L'alimentation électrique sélective d'un enroulement déterminé permet de positionner une face correspondante du cube dans un plan préférentiel.Figl 1 illustrates, by way of example, a series αe display modules ^ according to the invention, intended to constitute, individually or in combination, a panel 1 display of a representation in the general sense.

The cubes 8 of a column are also separated by the interval _I_ allowing to obtain a symmetrical visual effect. Each cube 8 has four display faces _F of different colors, one of the faces of which is positioned in a display plane _P which is substantially set back from the edges of the sides 4 (fig. 3). A display element 7, particularly suitable for the invention, has been described in US Pat. No. 4,558,267. According to this patent, each cube comprises, internally, a motor member having four stator windings mounted in relation to a rotor equipped of a magnet and wedged in rotation on the cube. The selective electrical supply of a determined winding makes it possible to position a corresponding face of the cube in a preferential plane.
Chaque module comporte, également,- une grille 11 destinée à masquer les intervalles I. séparant les faces _F du cube qui s'étendent selon le plan d'affichage P. La grille 11 est conçue de manière à assurer La libre rotation des cubes 8, tout en permettant de masquer au mieux Les intervalles inter-cubes pour atténuer l'effet visuel dû à de telles discontinuités de couleurs. La grille 11 est ainsi montée dans le plan d'affichage P ou en avant de ce plan, par rapport au fond du boîtier. A cet effet, La grille 11 est munie, verticalement, de plusieurs séries d'entretoises 12 destinées à s'intercaler entre les bords avants 5.. des plaques 5, de manière à assurer un positionnement des plaques et un montage stable de La grille. Avantageusement, La grille présente une couleur grise, afin de créer un effet visuel de fusion des couleurs présentées par les faces des cubes, à savoir rouge, vert, bleu et blanc.Each module also includes - a grid 11 intended to mask the intervals I. separating the faces _F of the cube which extend along the display plane P. The grid 11 is designed so as to ensure the free rotation of the cubes 8, while making it possible to mask the inter-cube intervals as well as possible to attenuate the visual effect due to such discontinuities of colors. The grid 11 is thus mounted in the display plane P or in front of this plane, relative to the bottom of the housing. To this end, the grid 11 is provided, vertically, with several series of spacers 12 intended to be inserted between the front edges 5 .. of the plates 5, so as to ensure positioning of the plates and stable mounting of the grid. . Advantageously, the grid has a gray color, in order to create a visual effect of fusion of the colors presented by the faces of the cubes, namely red, green, blue and white.
Chaque module K est équipé, également, d'un panneau de façade transparent 13 recouvrant La grille de masquage et monté sur les côtés 4 du boîtier. Le panneau de façade 13, qui est conçu pour protéger Les cubes 8, est, de préférence, scellé hermétiquement sur les côtés 4.Each module K is also equipped with a transparent front panel 13 covering the masking grid and mounted on the sides 4 of the housing. The front panel 13, which is designed to protect the cubes 8, is preferably hermetically sealed on the sides 4.
Chaque module M^ comporte aussi une carte de contrôle 14 montée parallèlement et à distance du fond 3 du boîtier et sur laquelle les plaques intermédiaires 5, qui constituent des circuits imprimés, se trouvent raccordées électriquement, à L'aide, par exemple, de connecteurs non représentés. La carte de contrôle 14 est équipée d'un microcontrôleur 15 permettant, notamment, de piloter des moyens 16 adaptés pour assurer la sélection et La commande des organes moteur 9. Tel que cela ressort plus précisément de La fig. 4, les moyens de sélection et de commande 16 sont constitués par des interrupteurs de rangées 16.. reliés chacun aux enroulements _E des organes moteurs disposés selon une rangée _R.. Les moyens 16 comportent des interrupteurs de colonnes 16^ connectés chacun directement à un enroulement JΞ de chaque organe moteur 9, disposé selon une colonne. Dans l'exemple illustré, chaque interrupteur de rangées 16_, est connecté aux 32 enroulements des organes moteurs 9 d'une rangée, tandis que chaque interrupteur de colonnes 16? est relié à 10 enroulements placés en parallèle, appartenant aux organes moteur 9 placés selon une colonne. Il est à noter que Les enroulements, connectés en parallèle et raccordés à un interrupteur de colonnes identique, permettent de positionner les mêmes faces des cubes correspondants dans un plan donné. Par ailleurs, chaque enroulement E est muni d'une diode 18 placée en série entre un enroulement etEach module M ^ also includes a control card 14 mounted parallel and at a distance from the bottom 3 of the housing and on which the intermediate plates 5, which constitute printed circuits, are electrically connected, using, for example, connectors not shown. The control card 14 is equipped with a microcontroller 15 making it possible, in particular, to control means 16 adapted to ensure the selection and the control of the motor members 9. As is shown more precisely in FIG. 4, the selection and control means 16 are constituted by row switches 16 .. each connected to the windings _E of the driving members arranged in a row _R .. The means 16 comprise column switches 16 ^ each connected directly to a winding JΞ of each motor member 9, arranged in a column. In the example illustrated, each row switch 16_ is connected to the 32 windings of the drive members 9 in a row, while each column switch 16 ? is connected to 10 windings placed in parallel, belonging to the motor members 9 placed according to a column. It should be noted that the windings, connected in parallel and connected to an identical column switch, make it possible to position the same faces of the corresponding cubes in a given plane. Furthermore, each winding E is provided with a diode 18 placed in series between a winding and
L'interrupteur 16-, correspondant. De préférence, Les interrupteurs 16. et 16-, sont formés par des transistors.Switch 16-, corresponding. Preferably, the switches 16. and 16-, are formed by transistors.
Les interrupteurs 16_., 16? se trouvent raccordés, par une double Ligne d'alimentation comportant une ligne d'alimentation de puissance électrique _AP et une ligne de transmission de données TD à un connecteur 19 adapté sur le fond 3 du boîtier. Le connecteur 19 est destiné à recevoir un connecteur complémentaire 21 relié à une unité centrale 22, Localisée ou non à proximité du panneau d'affichage. La commande sélective des cubes 8 est assurée, d'une part, par. l'alimentation séquentielle ou successive de chaque interrupteur 16. et, d'autre part, par l'alimentation des interrupteurs 16? associés aux enroulements devant être commandés. Ainsi, les organes moteur de chaque rangée sont alimentés successivement, de sorte qu'à un instant déterminé une unique rangée d'organes moteur est alimentée (fig. 5). La commande individuelle des enroulements JΞ est réalisée par L'intermédiaire des interrupteurs de colonnes 16?. Les diodes 18 empêchent la circulation du courant dans les enroulements _E non sélectionnés. L'agencement des moyens 16 de sélection et de commande, décrits ci-dessus, permet de mettre en oeuvre un nombre réduit d'interrupteurs. De plus, la commande séquentielle des rangées permet, pour une même tension d'alimentation, de réduire la puissance consommée d'un facteur correspondant au nombre de rangées. Cette réduction de la puissance consommée permet d'obtenir une dissipation 'diminuée de chaleur, ce qui augmente la fiabilité du module.The switches 16_., 16 ? are connected, by a double supply line comprising an electrical power supply line _AP and a data transmission line TD to a connector 19 adapted on the bottom 3 of the housing. The connector 19 is intended to receive a complementary connector 21 connected to a central unit 22, located or not near the display panel. Selective control of cubes 8 is ensured, on the one hand, by. the sequential or successive supply of each switch 16. and, on the other hand, by the supply of switches 16 ? associated with the windings to be ordered. Thus, the drive members of each row are supplied successively, so that at a given instant a single row of drive members is supplied (fig. 5). The individual control of the windings JΞ is carried out by means of the column switches 16 ? . The diodes 18 prevent the flow of current in the windings _E not selected. The arrangement of the selection and control means 16, described above, makes it possible to implement a reduced number of switches. In addition, the sequential row control allows, for the same supply voltage, to reduce the power consumed by a factor corresponding to the number of rows. This reduction in power consumption provides a dissipation 'less heat, which increases the reliability of the module.
De préférence, chaque module d'affichage comporte un dispositif 23 de mesure de courant circulant dans les enroulements E, de manière à vérifier le fonctionnement des cubes 8. Le dispositif de mesure 23 comporte un commutateur 24, monté en série sur une ligne d'alimentation provenant du connecteur 19 et connecté aux interrupteurs de rangées 16... Le commutateur 24 comporte, en parallèle, une résistance 25 montée en série avec une dioαe électroluminescente 26 d'un photo-coupleur 27 dont Le transistor 28 est apte à délivrer un signal de sortie correspondant au passage de courant dans un enroulement donné.Preferably, each display module includes a device 23 for measuring the current flowing in the windings E, so as to check the operation of the cubes 8. The measuring device 23 comprises a switch 24, mounted in series on a supply line coming from the connector 19 and connected to the row switches 16 ... The switch 24 comprises, in parallel, a resistor 25 connected in series with an electroluminescent dioαe 26 of a photo-coupler 27, the transistor 28 of which is capable of delivering an output signal corresponding to the passage of current in a given winding.
Lorsque l'unité centrale 22 assure la commande αes interrupteurs 16..,. 16-,, le commutateur 24 est fermé. Si un test de fonctionnement des cubes 8 doit être effectué, le commutateur 24 est ouvert, de sorte que la diode 26 est placée en série sur la ligne d'alimentation. Ensuite, L'interrupteur 16- de la première rangée est piloté, ainsi αuε Le premier interrupteur de colonnes, afin de permettre une circulation de courant dans l'enroulement correspondant. Le signal de sortie délivré par .le transistor 28 est stocké dans une mémoire, puis les interrupteurs de colonnes sont commandés successivement et l'opération est renouvelée pour chacune des rangées.When the central unit 22 controls the switches 16 ..,. 16- ,, the switch 24 is closed. If a function test of the cubes 8 is to be carried out, the switch 24 is open, so that the diode 26 is placed in series on the supply line. Then, the switch 16- of the first row is controlled, thus αuε The first column switch, in order to allow a flow of current in the corresponding winding. The output signal delivered by the transistor 28 is stored in a memory, then the column switches are controlled successively and the operation is repeated for each of the rows.
Un tel dispositif permet donc de déterminer si un courant circule normalement dans les enroulements des différents organes moteurs du module. Cette opération de contrôle est déclenchée périodiquement par l'unité centrale. Si un défaut apparaît, un second contrôle est effectué et une alarme est émise si le défaut subsiste. Le module d'affichage décrit ci-dessus présente un hautSuch a device therefore makes it possible to determine whether a current normally flows in the windings of the various motor members of the module. This control operation is triggered periodically by the central unit. If a fault appears, a second check is carried out and an alarm is issued if the fault remains. The display module described above has a high
•niveau de fiabilité et assure un contrôle permanent du bon fonctionnement de L'ensemble des organes moteurs associés aux cubes de visualisation. Bien entendu, le module selon l'invention peut présenter des tailles diverses, en relation du nombre de cubes utilisés pour assurer la représentation d'un message donné. • level of reliability and ensures permanent control of the proper functioning of all the motor components associated with the display cubes. Of course, the module according to the invention can have various sizes, in relation to the number of cubes used to ensure the representation of a given message.
Avantageusement, une série de modules d'affichage selon l'invention peuvent être associés ensemble pour constituer un panneau d'affichage de dimensions choisies. A cet effet, Les modules J1 sont destinés à être placés côte à côte, en minimisant les jeux de montage J intervenant entre les côtés voisins des modules, de manière à éviter L'apparition d'une discontinuité dans La représentation figurée. De plus, afin de créer, par l'ensemble des modules constituant un panneau, une image d'ensemble qui ne présente pas de distorsions géométriques à la frontière entre les différents modules, Les rangées _R et Les colonnes C de chaque modulé sont séparées, à partir du centre du module jusqu'aux côtés 4, par un intervalle _I à pas progressif, de préférence identique pour Les colonnes et les rangées. Avantageusement, chaque rangée ou colonne d'un module est séparée, respectivement, d'une rangée ou d'une colonne voisine d'un autre module, par un intervalle déterminé dont la mesure correspond au pas de progression des modules. Le pas de progression des modules est choisi de manière que l'intervalle inter-module présente une mesure suffisante pour correspondre à L'épaisseur de deux côtés, à Laquelle s'ajoute le jeu de montage _J_ intervenant entre deux modules. La disposition progressive des cubes reste imperceptible visuellement, tout en offrant la possibilité de ménager un intervalle suffisant pour la réalisation de côtés d'épaisseur convenable entre lesquels un jeu de montage subsiste. Bien entendu, la grille 11 présente aussi un pas progressif correspondant, pour assurer un masquage correct des intervalles intervenant entre les cubes.Advantageously, a series of display modules according to the invention can be associated together to constitute a display panel of selected dimensions. To this end, the modules J1 are intended to be placed side by side, minimizing the mounting clearances J occurring between the neighboring sides of the modules, so as to avoid the appearance of a discontinuity in the figurative representation. In addition, in order to create, by all the modules constituting a panel, an overall image which does not present geometric distortions at the border between the different modules, the rows _R and the columns C of each module are separated, from the center of the module to the sides 4, by an interval _I with progressive step, preferably identical for the columns and the rows. Advantageously, each row or column of a module is separated, respectively, from a row or a column adjacent to another module, by a determined interval whose measurement corresponds to the step of progression of the modules. The step of progression of the modules is chosen so that the inter-module interval has a sufficient measurement to correspond to the thickness of two sides, to which is added the mounting clearance _J_ occurring between two modules. The progressive arrangement of the cubes remains visually imperceptible, while offering the possibility of providing a sufficient interval for the production of sides of suitable thickness between which a mounting gap remains. Of course, the grid 11 also has a corresponding progressive pitch, to ensure correct masking of the intervals occurring between the cubes.
Pour assurer un positionnement côte à côte de plusieurs modules d'affichage, le fond 3 de chaque moduLe est muni d'au moins un et, de préférence, trois organes 28 de montage, de préférence amovible, sur une structure porteuse 29. Tel que cela apparaît plus précisément à la fig. 6, chaque organe de montage 28 est formé par une cavité conique 29 ménagée dans le fond 3 du boîtier, en relation de proximité d'un coin du boîtier. Chaque cavité 29 est destinée à coopérer avec un cône complémentaire 31 assurant une fonction de positionnement relatif des modules.To ensure positioning side by side of several display modules, the bottom 3 of each module is provided with at least one and preferably three mounting members 28, preferably removable, on a support structure 29. As this appears more precisely in fig. 6, each mounting member 28 is formed by a conical cavity 29 formed in the bottom 3 of the housing, in proximity relation to a corner of the housing. Each cavity 29 is intended to cooperate with a complementary cone 31 ensuring a relative positioning function of the modules.
Par ailleurs, chaque cavité 29 est entourée par une couronne 32 à auto-accrochage, fixée sur le fond 3 et conçue pour coopérer avec un anneau 33 à auto-accrochage entourant la grande base du cône de positionnement 31. Les surfaces des couronnes 32 et des anneaux 33 à auto-accrochaαe sont déterminées de manière à obtenir une force de maintien suffisante pour supporter le poids du module, tout en limitant L'effort d'arrachement intervenant au moment de l'extraction s1effectuant par une sollicitation exercée sur le panneau de façade 13, selon une direction normale, par l'intermédiaire, par exemple, d'un outil du type ventouse. De préférence, pour faciliter les opérations de montage et de démontage d'un module, le fond 3 de chaque module possède des dimensions plus réduites que le panneau de façade 13, de manière à former des bords 4 en dépouille. Avantageusement, un connecteur complémentaire 21 et trois cônes de positionnement 31, associés aux anneaux de fixation 33, sont montés sur une platine 35 qui est adaptée sur la structure porteuse 29. Tel que cela apparaît plus précisément à la fig. 1, la structure porteuse 29 est constituée par des traverses 29. supportées par des montants 29- espacés. Chaque traverse 29. est constituée sous la forme d'un profilé comportant des bords tombés 29 destinés à coopérer avec des rainures 35. portées par La platine 35 de positionnement et de fixation. Les platines 35 sont placées sur Les traverses, de manière que chaque module, d'une part, soit positionné et fixé par L'intermédiaire des trois cavités 29 coopérant avec trois cônes 31 appartenant à des platines'différentes et, d'autre part, se trouve raccordé électriquement à l'aide du connecteur 19, à un connecteur complémentaire 21 placé sur une autre platine. Les modules d'affichage, équipés chacun d'organes de montage 28 et de raccordement électrique 19, se trouvent donc particulièrement aptes à former des panneaux d'affichage dont la surface de présentation d'un message n'est pas Limitée. Les modules d'affichage d'un panneau sont connectés en parallèle sur une double ligne d'alimentation par Laquelle l'unité centrale 22 véhicule les informations de sélection des modules et de commande des cubes. L'unité centrale 22 assure, pour chaque module et par l' intermédia re du microcontrôleur 15 correspondant, la commande des interrupteurs 16 pilotant Les organes moteurs 9. A cet effet, chaque module est pourvu d'une adresse qui lui est propre. permettant de transmettre des informations sélectives à chaque module. En mode fonctionnement, tous les modules scrutent, en permanence, la double ligne d'alimentation, dans l'attente d'une adresse. Lorsqu'une adresse apparaît, chaque module compare cette adresse à son adresse propre. Si les adresses sont identiques, Le module de base concerné prend en compte les informations suivantes de commande et de sélection des organes moteurs. Lrs modules, pour Lesquels la comparaison des adresses aboutit à une non identité, ignorent Les informations de commande et de sélection. De telles fonctions sont assumées par le mîcrocontrôLeur 15 adapté sur les cartes de contrôle 14 de chaque module.Furthermore, each cavity 29 is surrounded by a self-latching crown 32, fixed on the bottom 3 and designed to cooperate with a self-latching ring 33 surrounding the large base of the positioning cone 31. The surfaces of the crowns 32 and self-hanging rings 33 are determined so as to obtain a holding force sufficient to support the weight of the module, while limiting the tearing force occurring at the time of extraction s 1 effected by a stress exerted on the front panel 13, in a normal direction, by the 'Intermediate, for example, a tool of the suction cup type. Preferably, to facilitate the assembly and disassembly operations of a module, the bottom 3 of each module has smaller dimensions than the front panel 13, so as to form edges 4 in clearance. Advantageously, a complementary connector 21 and three positioning cones 31, associated with the fixing rings 33, are mounted on a plate 35 which is fitted to the support structure 29. As shown more precisely in FIG. 1, the supporting structure 29 is constituted by crosspieces 29. supported by uprights 29- spaced apart. Each cross member 29. is formed in the form of a profile having fallen edges 29 intended to cooperate with grooves 35. carried by the plate 35 for positioning and fixing. The plates 35 are placed on the crosspieces, so that each module, on the one hand, is positioned and fixed by means of the three cavities 29 cooperating with three cones 31 belonging to different plates and, on the other hand, is electrically connected using the connector 19, to a complementary connector 21 placed on another plate. The display modules, each equipped with mounting members 28 and electrical connection 19, are therefore particularly suitable for forming display panels whose surface for presenting a message is not limited. The display modules of a panel are connected in parallel on a double supply line through which the central unit 22 conveys the information for selecting the modules and controlling the cubes. The central unit 22 provides, for each module and by means of the corresponding microcontroller 15, the control of the switches 16 controlling the drive members 9. For this purpose, each module is provided with its own address. allowing selective information to be transmitted to each module. In operating mode, all the modules continuously scan the double supply line, pending an address. When an address appears, each module compares this address with its own address. If the addresses are identical, the basic module concerned takes into account the following information for controlling and selecting the drive components. Their modules, for which the comparison of addresses results in a non-identity, ignore the order and selection information. Such functions are assumed by the microcontroller 15 adapted on the control cards 14 of each module.
La description qui suit décrit un procédé permettant d'affecter une adresse à chaque module constitutif d'un panneau d'affichage. L'adresse de chaque module est affectée au cours de L'installation des modules sur La structure porteuse qui s'effectue successivement. Par ailleurs, chaque module comporte αes moyens programmés dans le microcontrôleur 15, permettant de configurer le module lors de sa fabrication dans un mode installation. Pour ce mode installation, toute adresse reçue par le microcontrôleur 15 est renvoyée en écho et Lorsqu'un nombre déterminé d'adresses consécutives a été reçu, cette adresse est mémorisée dans une mémoire non volatile installée sur la carte de contrôle 14. Le module passe ainsi du mode installation au moαe fonctionnement pendant lequel s'effectuent la commande et La sélection des organes moteurs.The following description describes a method for assigning an address to each module constituting a display panel. The address of each module is assigned during the installation of the modules on the supporting structure, which is carried out successively. Furthermore, each module comprises αes means programmed in the microcontroller 15, making it possible to configure the module during its manufacture in an installation mode. For this installation mode, any address received by the microcontroller 15 is echoed back and When a determined number of consecutive addresses has been received, this address is stored in a non-volatile memory installed on the control card 14. The module switches thus from the installation mode to the operating mode during which the control and the selection of the driving members are carried out.
L'affectation d'une adresse à chaque module s'effectue plus précisément de la manière suivante. Un premier module est positionné sur la structure porteuse, de manière à relier la carte de contrôle' 14 de ce module à l'unité centrale 22, par le raccordement des connecteurs 19 et 21. L'unité centrale émet une adresse déterminée, répétée successivement et destinée à être renvoyée en écho, à chaque fois, par les moyens de configuration du module concerné. Ces moyens de configuration comparent l'adresse reçue à l'adresse précédente et l'unité centrale compare, pour chaque adresse, l'adresse émise et l'adresse reçue en écho. Si pour un nombre successif de valeurs l'adresse reçue par Le module correspond à l'adresse reçue précédemment, cette adresse est mémorisée dans la mémoire non" olati Le, de manière que le module passe du mode installation au mode fonctionnement. Dans ce mode de fonctionnement, le module, doté d'une adresse, ne prend plus en compte les adresses envoyées au cours de la phase d'installation par l'unité centrale.The assignment of an address to each module is carried out more precisely as follows. A first module is positioned on the supporting structure, so as to connect the control board '14 of this module to the central unit 22, by connecting the connectors 19 and 21. The CPU transmits a specific address, repeated successively and intended to be echoed each time by the configuration means of the module concerned. These configuration means compare the address received with the previous address and the central unit compares, for each address, the address sent and the address received. echoing. If for a number of successive values of the address received by the module corresponds to the address previously received, this address is stored in the memory not "The olati, so that the pass module installation mode to the operation mode. In this mode the module, with an address, no longer takes into account the addresses sent during the installation phase by the central unit.
Après L'affectation d'une adresse à un module, l'unité centrale 22 émet une adresse suivante, destinée à être affectée au module qui sera ultérieurement installé. Les modules sont donc installés à tour de rôle sur la structure porteuse, de manière à leur affecter une adresse propre au cours de leur montage, qui correspond à leur rang d'installation.After the assignment of an address to a module, the central unit 22 transmits a following address, intended to be assigned to the module which will be subsequently installed. The modules are therefore installed in turn on the supporting structure, so as to assign them a specific address during their assembly, which corresponds to their installation rank.
