Description

Dispositif de surveillance, de gestion et de pilotage à distance de plusieurs sites à partir d'un point central, au moyen de balises auto¬ configurables. Device for remote monitoring, management and control of several sites from a central point, using self-configurable beacons.
L'invention concerne la gestion technique centralisée. Elle a pour but d' améliorer, en les rendant plus souples, plus économiques et plus performantes les installations utilisées pour la surveillance, la gestion et le pilotage d'une pluralité de sites éloignés les uns des autres à partir d'un point central. Les domaines d'application de l'invention recouvrent l'ensemble des domaines d'application de la gestion technique centralisée, à savoir la télésurveillance et la télégestion. Les secteurs utilisateurs sont donc extrêmement vastes et comprennent notamment l'habitat, l'industrie, l'agriculture et les loisirs. Plus généralement, l'invention trouve ses applications dans tous les cas où il est nécessaire de surveiller, gérer ou piloter à distance une pluralité de sites éloignés les uns des autres, sans qu'il soit possible ou souhaitable, pour des raisons techniques ou économiques, de créer une liaison filaire entre les différents sites et le point central. L'invention s'applique en effet plus spécifiquement à des balises de surveillance, de gestion ou de pilotage communiquant avec une unité centrale par une liaison non filaire, préférentiellement réalisée par voie hertzienne.The invention relates to centralized technical management. Its purpose is to improve, by making them more flexible, more economical and more efficient, the installations used for monitoring, managing and piloting a plurality of remote sites from one another from a central point. The fields of application of the invention cover all the fields of application of centralized technical management, namely remote monitoring and remote management. The user sectors are therefore extremely large and include in particular housing, industry, agriculture and leisure. More generally, the invention finds its applications in all cases where it is necessary to monitor, manage or control remotely a plurality of remote sites from each other, without it being possible or desirable, for technical or economic reasons , to create a wire link between the different sites and the central point. The invention applies more specifically to surveillance, management or piloting beacons communicating with a central unit by a non-wired link, preferably carried out by radio.
De nombreuses solutions ont été proposées pour réaliser des systèmes de gestion technique centralisée. Dans tous les cas, on trouve d'une part une unité centrale, comprenant le plus souvent un module de traitement de l'information et un module d'émission réception et d'autre part une pluralité de balises communiquant avec l'unité centrale soit par voie hertzienne, soit par voie filaire, soit encore par voie lumineuse ou infrarouge. On constate cependant que le mode de conception et de réalisation actuel des balises impose dans tous les cas la réalisation de balises spécifiques, ou, à tout le moins, spécifiquement adaptées pour chacune des applications de la gestion technique centralisée. De plus, à l'intérieur d'une même application, on peut avoir besoin de doter certaines balises de fonctions ou de rôles différentiés: certaines balises ont un simple rôle d'émission d'alertes, d'autres servent à transmettre des ordres, d'autres encore doivent mémoriser des informations. Les fabricants de systèmes de gestion technique centralisée doivent donc créer des balises spécifiques pour chaque application, et à i'intérieur de chaque application, des balises adaptées aux différentes fonctions souhaitées. Bien qu'un certain nombre d'éléments communs soient utilisés, comme les carters, les cartes d'alimentation et certaines cartes logiques, le coût de conception et de réalisation de ces différentes balises reste particulièrement élevé, ce qui n'est pas compatible avec la large diffusion des systèmes de gestion technique centralisée que devrait provoquer les nombreuses potentialités par eux offertes. Cet état de fait s'explique par le prix d'achat des composants unitaires permettant de conférer à une balise telle ou telle caractéristique, et par le coût de l'implantation des dits composants à l'intérieur d'une balise. Certains systèmes proposés sur le Marché utilisent en effet des balises relativement standardisées, mais, dans ce cas, on constate d'une part que ces balises comportent un grand nombre de composants excédentaires par rapport aux fonctions qui leur sont demandées, composants dont le coût d'achat et d'implantation grèvent le prix ce revient des systèmes et d'autre part que le coût de l'adaptation de ces balises aux fonctions souhaitées représente un obstacle important, compte tenu du niveau de qualification requis pour les personnes réalisant cette adaptation.Many solutions have been proposed for realizing centralized technical management systems. In all cases, there is on the one hand a central unit, most often comprising an information processing module and a transmission reception module and on the other hand a plurality of beacons communicating with the central unit either over the air, either by wire, or by light or infrared. However, it is noted that the current design and embodiment of the beacons in all cases requires the production of specific beacons, or, at the very least, specifically adapted for each of the applications of centralized technical management. In addition, within the same application, we may need to provide certain tags with differentiated functions or roles: some tags have a simple role of issuing alerts, others are used to transmit orders, still others have to memorize information. Manufacturers of centralized technical management systems must therefore create specific tags for each application, and within each application, tags adapted to the different functions desired. Although a certain number of common elements are used, such as casings, power supply cards and certain logic cards, the cost of design and production of these various beacons remains particularly high, which is not compatible with the wide dissemination of centralized technical management systems which should be brought about by the numerous possibilities offered by them. This state of affairs is explained by the purchase price of the unitary components making it possible to confer on a beacon such or such characteristic, and by the cost of the implementation of said components inside a beacon. Certain systems offered on the market do indeed use relatively standardized tags, but, in this case, it can be seen, on the one hand, that these tags include a large number of components in excess of the functions required of them, components whose cost of purchasing and setting up the cost of the systems and on the other hand that the cost of adapting these beacons to the desired functions represents a significant obstacle, given the level of qualification required for the people carrying out this adaptation.
L'invention propose de réaliser des systèmes de gestion technique centralisée intégrant des balises dont le mode de conception et de réalisation permette de s'affranchir des inconvénients évoqués ci-dessus. Plus généralement, l'invention est caractérisée par une architecture des balises qui soit compatible non seulement avec l'utilisation d'un seul et unique type de balises pour des applications très différentes les unes des autres, mais encore avec l'affectation d'une parmi plusieurs fonctions différentes, selon les besoins, à chacune de ces balises utilisées dans le cadre d'une même application.The invention proposes to realize centralized technical management systems incorporating tags whose design and embodiment allows to overcome the drawbacks mentioned above. More generally, the invention is characterized by an architecture of beacons which is compatible not only with the use of a single type of beacons for very different applications from each other, but also with the allocation of a among several different functions, as required, to each of these tags used within the framework of the same application.
Un objectif principal de l'invention est de proposer des systèmes de télésurveillance et de télégestion qui soient facilement adaptables à des utilisations extrêmement variées, tout en utilisant des balises standardisées identiques les unes aux autres et fabriquées en grande série.A main objective of the invention is to propose remote monitoring and remote management systems which are easily adaptable to extremely varied uses, while using standardized beacons identical to each other and mass produced.
Un objectif complémentaire de l'invention est de faciliter les opérations de mise en configuration des balises, et de faire en sorte que ces opérations puissent être accomplies y compris par des utilisateurs ou visiteurs des sites équipés des dites balises, alors même que ces utilisateurs ne disposeraient d'aucune compétences particulières. Un objectif supplémentaire de l'invention est de permettre une très sensible diminution des prix de revient des composants des systèmes de gestion technique centralisée, ainsi qu'une nette réduction des coûts de conception, de mise en place et d'exploitation de tels systèmes. A terme, la présente invention a pour ambition, grâce à la souplesse d'utilisation et aux économies d'échelle qu'elle engendre, d'élargir le champ d'application de la gestion technique centralisée.A complementary objective of the invention is to facilitate the configuration operations for the beacons, and to ensure that these operations can be carried out including by users or visitors to sites equipped with said beacons, even when these users do not have no special skills. An additional objective of the invention is to allow a very significant reduction in the cost prices of the components of the centralized technical management systems, as well as a clear reduction in the costs of design, installation and operation of such systems. Ultimately, the present invention aims, thanks to the flexibility of use and the economies of scale which it generates, to widen the field of application of centralized technical management.
Ces objectifs, ainsi que d'autres qui apparaîtront par la suite, sont atteints grâce à des installations comprenant, de façon classique, d'une part une unité centrale comportant un système de traitement et de mémorisation de l'information et une unité d'émission/réception et d'autre part une pluralité de balises destinées à être implantées dans les sites devant être surveillés, gérés ou pilotés à partir de l'unité centrale.These objectives, as well as others which will appear subsequently, are achieved by means of installations comprising, in a conventional manner, on the one hand a central unit comprising a system for processing and memorizing information and a unit for transmission / reception and on the other hand a plurality of beacons intended to be installed in the sites to be monitored, managed or controlled from the central unit.
Un avantage essentiel de l'invention est que, au lieu d'utiliser des balises conçues et réalisées pour chacune des applications et pour chaque fonction et/ou série de fonctions dans le cadre d'une même application, les systèmes de gestion technique centralisée selon l'invention ne font appel qu'à un seul et unique type de balise dont la conception et le mode de réalisation permet non seulement l'utilisation dans des applications particulièrement variées mais encore la spécialisation, réalisée particulièrement facilement et rapidement, de chaque balise à une ou plusieurs fonctions choisies par l'utilisateur.An essential advantage of the invention is that, instead of using beacons designed and produced for each of the applications and for each function and / or series of functions within the framework of the same application, the centralized technical management systems according to the invention uses only one single type of beacon whose design and embodiment allows not only the use in particularly varied applications but also the specialization, carried out particularly easily and quickly, of each beacon one or more functions chosen by the user.
Un avantage complémentaire de l'invention est que les fonctions affectées à telle ou telle balise ne sont pas fixées une fois pour toutes, mais peuvent être très facilement et très rapidement modifiées par l'exploitant du système, voire par tel utilisateur disposant des clés adéquates.An additional advantage of the invention is that the functions assigned to such and such a tag are not fixed once and for all, but can be very easily and very quickly modified by the system operator, or even by such user having adequate keys .
Un autre avantage du système proposé est que cette possibilité d' adaptation des mêmes balises à différentes applications, et, dans le cadre d'une même application, à différentes fonctions, est obtenue non pas au prix d'une complexité accrue des dites balises, mais, bien au contraire, grâce à une simplification et une rationalisation de la réalisation de ces éléments, qui permet d'abaisser significativement leur prix de revient et leur coût d'installation.Another advantage of the proposed system is that this possibility of adapting the same tags to different applications, and, within the framework of the same application, to different functions, is obtained not at the cost of an increased complexity of said tags, but, on the contrary, thanks to a simplification and a rationalization of the production of these elements, which makes it possible to significantly lower their cost price and their installation cost.
Ces avantages sont conférés aux balises par le fait qu'elles sont constituées d'une carte principale comportant un composant de type "Applied Silicon Integreted Circuit", c'est à dire "Circuit intégré sur une puce de Silicone ayant une application déterminée" communément connues sous l'appellation "ASIC" qui sera utilisée dans la suite de la présente description, connecté d'une part à un module de configuration, ces deux éléments étant connectés entre eux par au moins 13 liaisons filaires, 3 de ces liaisons étant affectées à la sélection des fréquences et les dix autres étant utilisées pour conférer à la balise les fonctions souhaitées et d'autre part à un bornier destiné à recevoir des informations et/ou de l'énergie ou à émettre des ordres depuis ou vers le milieu. Le composant de type ASIC est auto configurable. En d'autres termes, ce composant va être capable de recevoir et de mémoriser des informations qui auront pour effet de lui conférer un état donné. Ces informations proviendront d'une part du module de configuration intégré à la balise auquel ce composant est connecté et, d'autre part, par voie hertzienne, du point central lors de chaque séquence de communication initiée par ce dernier; ainsi, les intervalles et la durée des interrogations, c'est à dire le fenêtrage, pourront être ordonnés à chaque balise qui se conformera à ces consignes pour le cycle suivant. En conséquence, à partir de balises strictement identiques et fabriquées en grande série, le fabricant ou l'installateur du système pourra adapter ces éléments à une application donnée. Dans un deuxième temps, l'utilisateur conférera, au moyen du module de configuration et du bornier de raccordement et des ordres émis par le point central, une parmi plusieurs fonctions possibles à chacune des balises implantées sur le site à gérer ou à surveiller.These advantages are conferred on the tags by the fact that they consist of a main card comprising a component of the "Applied Silicon" type. Integreted Circuit ", that is to say" Integrated circuit on a silicone chip having a determined application "commonly known under the name" ASIC "which will be used in the rest of this description, connected on the one hand to a module configuration, these two elements being connected to each other by at least 13 wired links, 3 of these links being assigned to the frequency selection and the ten others being used to give the tag the desired functions and on the other hand to a terminal block intended to receive information and / or energy or to issue orders from or to the medium. The ASIC component is self configurable. In other words, this component will be capable of receiving and memorizing information. which will have the effect of giving it a given state. This information will come, on the one hand, from the configuration module integrated into the tag to which this component is connected and, on the other hand , over the air, from the central point during each communication sequence initiated by the latter; thus, the intervals and the duration of the interrogations, that is to say the windowing, can be ordered at each beacon which will conform to these instructions for the following cycle. Consequently, from strictly identical tags and mass produced, the manufacturer or installer of the system will be able to adapt these elements to a given application. In a second step, the user will confer, by means of the configuration module and the connection terminal block and orders issued by the central point, one of several possible functions to each of the beacons located on the site to be managed or monitored.
D'autres avantages et caractéristiques de l'invention apparaîtront à la lecture suivante d'un mode de réalisation préférentiel de l'invention, donné à simple titre indicatif, et des dessins annexés dans lesquels:Other advantages and characteristics of the invention will appear on the following reading of a preferred embodiment of the invention, given for information only, and of the appended drawings in which:
La FIGURE 1 représente un schéma d'ensemble d'un dispositif de gestion technique centralisée.FIGURE 1 represents an overall diagram of a centralized technical management device.
La FIGURE 2 représente une vue extérieure d'une balise selon l'invention.FIGURE 2 shows an exterior view of a beacon according to the invention.
La FIGURE 3 représente le mode de connexion des différents éléments internes caractérisant une Balise selon l'invention.FIGURE 3 represents the mode of connection of the various internal elements characterizing a Beacon according to the invention.
On constate que le dispositif selon l'invention comporte plusieurs niveaux d'intervention. Le premier niveau est le site qui doit bénéficier d'une surveillance ou d'un pilotage. Sur ce site, on installe une pluralité de capteurs (12), d'actionneurs (13) ou de compteurs (14). Par capteur, on entend par exemple des sondes de température ou d'hygrométrie, des détecteurs de niveau ou de Ph, des détecteurs d'incendie ou d'intrusion. Les actionneurs sont des relais permettant la mise en marche et la régulation de moteurs ou de machines. Les compteurs sont par exemple des circuits émettant une impulsion par événement unitaire survenant sur le process à surveiller. Chaque capteur (12), actionneur (13) ou compteur (14) implanté sur le site est relié à une balise (10). Dans une variante, une balise peut être associée à plusieurs capteurs et/ou actionneurs. Chaque balise est dotée d'une antenne (11) qui lui permet d'échanger des signaux hertziens avec une balise maître (20) située au point de centralisation des informations. Cette balise maître (20) qui émet et reçoit les informations par l'intermédiaire d'une antenne* (21) est connectée à une carte mère (22), cette dernière pouvant restituer les informations qu'elle collecte, par exemple au moyen d'une imprimante. L'ensemble d'une balise maître (21) et d'une carte mère (22) constitue un point central, qui représente le deuxième niveau d'un dispositif selon l'invention. Entre une balise maître (20) et les balises de sites qu'elle est susceptible de piloter, balises dont le nombre est compris entre 1 et 512, on choisira de réaliser toutes les liaisons hertziennes sur une seule et même fréquence, appelée fréquence de site. On notera qu'il est possible sélecter jusqu'à 9 fréquences différentes; en conséquence, on aura la possibilité de gérer jusqu'à 9 sites ou zones différents, comprenant chacun jusqu'à 512 balises. On aura alors 9 balises maîtres, connectées à autant de cartes mères. Chacune des cartes mères pourra être connectée à un système de traitement de l'information (24) préférentiellement constitué par un micro-ordinateur de type IBM-PC (marque déposée de International Business machine) ou compatible, qui constitue le troisième niveau du dispositif selon l'invention. La liaison entre le système de traitement de l'information (24) et la ou les cartes mères (22) pourra être réalisée en utilisant le réseau téléphonique commuté (23), chacune des cartes mères (22) étant munie d'un modem et d'un dispositif de mémorisation et de composition automatique des numéros. De plus, le raccordement des cartes mères (22) au réseau téléphonique commuté (23) permet l'utilisation de simples postes minitels pour consulter l'état du système, voire pour lui envoyer des ordres.It can be seen that the device according to the invention has several levels of intervention. The first level is the site which must benefit from surveillance or monitoring. On this site, a plurality of sensors (12) are installed, actuators (13) or counters (14). By sensor is meant, for example, temperature or humidity probes, level or pH detectors, fire or intrusion detectors. The actuators are relays for starting and regulating motors or machines. The counters are for example circuits emitting a pulse per unit event occurring on the process to be monitored. Each sensor (12), actuator (13) or counter (14) installed on the site is connected to a beacon (10). In a variant, a beacon can be associated with several sensors and / or actuators. Each beacon is provided with an antenna (11) which allows it to exchange radio signals with a master beacon (20) located at the information centralization point. This master beacon (20) which transmits and receives information via an antenna * (21) is connected to a motherboard (22), the latter being able to restore the information which it collects, for example by means of 'a printer. The assembly of a master beacon (21) and a motherboard (22) constitutes a central point, which represents the second level of a device according to the invention. Between a master beacon (20) and the site beacons that it is capable of controlling, beacons whose number is between 1 and 512, we will choose to carry out all the radio links on a single frequency, called site frequency . Note that it is possible to select up to 9 different frequencies; as a result, we will be able to manage up to 9 different sites or zones, each comprising up to 512 tags. We will then have 9 master tags, connected to as many motherboards. Each of the motherboards can be connected to an information processing system (24) preferably constituted by a microcomputer of IBM-PC type (registered trademark of International Business machine) or compatible, which constitutes the third level of the device according to the invention. The connection between the information processing system (24) and the motherboard (s) (22) can be carried out using the switched telephone network (23), each of the motherboards (22) being provided with a modem and a device for memorizing and automatically dialing numbers. In addition, the connection of motherboards (22) to the switched telephone network (23) allows the use of simple mini stations to consult the state of the system, or even to send orders to it.
On constate donc que l'architecture du dispositif selon l'invention permet d'envisager des applications extrêmement variées, et ce en bénéficiant d'une grande souplesse dans la conception et la réalisation des systèmes. On notera en particulier que les systèmes réalisés ne sont pas figés mais peuvent évoluer en fonction des besoins des utilisateurs.It can therefore be seen that the architecture of the device according to the invention makes it possible to envisage extremely varied applications, and this while benefiting from great flexibility in the design and implementation of the systems. We will note in particular that the systems produced are not fixed but can evolve according to the needs of the users.
En effet, une fois un dispositif selon l'invention installé, il est possible de rajouter autant de balises de sites que de besoin (dans la limite de 512 balises par site). Il est également possible de changer les affectations de telle ou telle balise, simplement en agissant sur le module de configuration (2) dont la dite balise est dotée, et, éventuellement en changeant les capteurs (12), actionneurs (13) ou compteurs (14) auxquels elle est raccordée par l'intermédiaire de son bornier (5). Enfin, et cet aspect est particulièrement important, on peut également décider d'affecter une ou plusieurs balises de site à un point central différent de celui auquel elles avaient été initialement reliées par voie hertzienne; il suffit pour ce faire d'agir sur le module de configuration (2) qui est connecté au composant principal de la balise, à savoir l'ASIC (1) auto-configurable, comme illustré sur la Figure 3.In fact, once a device according to the invention is installed, it is possible to add as many site tags as necessary (within the limit of 512 tags per site). It is also possible to change the assignments of this or that beacon, simply by acting on the configuration module (2) with which the said beacon is provided, and, possibly by changing the sensors (12), actuators (13) or counters ( 14) to which it is connected via its terminal block (5). Finally, and this aspect is particularly important, we can also decide to assign one or more site tags to a central point different from the one to which they were originally connected by radio; it suffices to act on the configuration module (2) which is connected to the main component of the beacon, namely the ASIC (1) self-configurable, as illustrated in Figure 3.
Ce composant principal de type ASIC (1) est constitué par une puce de silicium, d'une épaisseur faible par rapport à sa surface, dans laquelle ont été intégrés d'une part des circuits numériques et d'autre part des circuits analogiques. Dans une variante, ce composant pourra être dédoublé: on utilisera dans ce cas un composant spécialisé dans le traitement des informations numériques, et un composant spécialisé dans le traitement des informations analogiques, ces deux composants étant connectés entre eux de façon à se comporter comme un seul et même composant. L'élément simple ou dédoublé est en tous les cas relié à l'extérieur par une pluralité de liaisons filaires communément appelées entrées/sorties dont au moins 13 sont connectées à un module de configuration (2). La conception de l'ASIC (1) lui permet de réaliser des fonctions différentes en fonction de l'état dans lequel se trouve le module de configuration (2) auquel il est relié. De même, cet ASIC est réalisé de telle façon qu'il puisse réagir à l'une quelconque des 9 fréquences possibles en fonction de l'état dans lequel se trouve le module de configuration (2) auquel il est connecté. Le composant principal (1) comprend un nombre important d'entrées/sorties (environ 80); parmi ces entrées/sorties, au moins 13 sont reliées par des liaisons filaires au module de configuration (2) dont 3 (F0, F1, F2) sont affectées à la détermination , en fonction de l'état du module de configuration, de la fréquence de fonctionnement de la balise et les au moins 10 autres (SO à S9) sont affectées à la désignation, toujours en fonction de l'état de ce même module de configuration, des fonctions devant être remplies par la balise (10).This main component of the ASIC type (1) consists of a silicon chip, of small thickness compared to its surface, into which digital circuits have been integrated on the one hand and analog circuits on the other hand. In a variant, this component may be split: in this case, a component specialized in the processing of digital information, and a component specialized in the processing of analog information, will be used, these two components being connected together so as to behave like a single and same component. The simple or split element is in any case connected to the outside by a plurality of wired connections commonly called inputs / outputs, at least 13 of which are connected to a configuration module (2). The design of the ASIC (1) allows it to perform different functions depending on the state of the configuration module (2) to which it is connected. Likewise, this ASIC is designed in such a way that it can react to any of the 9 possible frequencies depending on the state in which the configuration module (2) is located to which it is connected. The main component (1) comprises a large number of inputs / outputs (about 80); among these inputs / outputs, at least 13 are connected by wire links to the configuration module (2) of which 3 (F0, F1, F2) are assigned to the determination, depending on the state of the configuration module, of the operating frequency of the beacon and the at least 10 others (SO to S9) are assigned to the designation, always according to the state of this same configuration module, functions to be fulfilled by the tag (10).
Le module de configuration (2) pourra être réalisé très simplement à partir d'une pluralité de commutateurs (6) (interrupteurs pouvant prendre au moins deux positions différentes) ou de cavaliers. On conférera donc à chaque balise de site une fréquence, une adresse, et une fonction par simples changements de positions des commutateurs (6) dont est muni le module de configuration (2). Dans la mesure où le dit module de configuration (2) comporte au moins 13 éléments susceptibles de prendre chacun 2 positions différentes, ce module pourra se trouver dans au moins 13 puissance 2 soit 169 états différents. Une fois cette opération de configuration effectuée et donc l'un des états possibles conféré à chacune des balises du site, les balises maîtres (20) pourront interroger successivement chacune des balises de sites (10) et surveiller ou piloter le process.The configuration module (2) can be produced very simply from a plurality of switches (6) (switches which can take at least two different positions) or jumpers. We will therefore give each site tag a frequency, an address, and a function by simple changes of positions of the switches (6) with which the configuration module (2) is provided. Insofar as said configuration module (2) comprises at least 13 elements capable of each taking 2 different positions, this module may be in at least 13 power 2, ie 169 different states. Once this configuration operation has been carried out and therefore one of the possible states given to each of the site beacons, the master beacons (20) can successively interrogate each of the site beacons (10) and monitor or control the process.
Cela étant, on a vu que l'un des avantages principaux du système était de permettre, grâce au mode de réalisation des composants ASIC, de très nombreux et très rapides changements de configuration et d'affectation des balises de site en fonction de l'évolution des besoins de surveillance et/ou de pilotage du process. Or, la mise en place de cavaliers ou le changement de position de commutateurs constitue une opération fastidieuse, dès lors que l'on dispose d'un grand nombre de balises de sites; de plus, ces opérations ne peuvent être confiées qu'à des personnes disposant de la formation adéquate. Pour un certains nombre d'applications, il pourra s'avérer intéressant de faire exploiter les très nombreuses possibilités de modification offertes par le dispositif de surveillance et de pilotage selon l'invention y compris par les utilisateurs et par le public.However, we have seen that one of the main advantages of the system was to allow, thanks to the embodiment of the ASIC components, very numerous and very rapid configuration changes and assignment of site tags according to the evolution of process monitoring and / or steering needs. However, the installation of jumpers or the change of position of switches constitutes a tedious operation, as soon as one has a large number of site tags; furthermore, these operations can only be entrusted to persons with adequate training. For a certain number of applications, it may prove advantageous to make use of the very numerous modification possibilities offered by the monitoring and control device according to the invention, including by users and by the public.
Dans ce but, le module de configuration (2) sera avantageusement relié à un dispositif de lecture d'informations (3) contenues sur une piste magnétique, le dit dispositif étant relié au module de configuration (2) et donc aux entrées/sorties (F0, F1, F2 et S0, S1, S2, S3, S4, S5, S6, S7, S8, S9) par l'intermédiaire d'un décodeur (4) comportant les moyens de modifier l'état dans lequel se trouve le module de configuration (2) en fonction des informations contenues sur la piste magnétique et transmises par le dispositof de lecture (3). On comprend dès lors qu'il est possible, grâce à ce dispositif de reconfiguration Instantanée des balises par carte magnétique, d'exploiter au mieux la très grande souplesse offerte par les installations selon l'invention. A cet effet, on fournira aux utilisateurs, en même temps que l'installation, une pluralité de cartes magnétiques, chaque carte correspondant à l'une des nombreuses configurations susceptibles d'être conférées à une balise.For this purpose, the configuration module (2) will advantageously be connected to a device for reading information (3) contained on a magnetic strip, said device being connected to the configuration module (2) and therefore to the inputs / outputs ( F0, F1, F2 and S0, S1, S2, S3, S4, S5, S6, S7, S8, S9) by means of a decoder (4) comprising the means of modifying the state in which the configuration module (2) according to the information contained on the magnetic strip and transmitted by the reading device (3). We therefore understand that it is possible, thanks to this reconfiguration device Instant beacons by magnetic card, to make the most of the great flexibility offered by the installations according to the invention. To this end, users will be provided, at the same time as the installation, with a plurality of magnetic cards, each card corresponding to one of the many configurations that can be given to a beacon.
A titre d'exemples, si l'installation sert à surveiller une unité industrielle, un employé pourra faire le tour de l'unité et faire lire à chacune des balises de site qu'il lui aura été demandé de modifier, la carte portant le numéro adapté. Dans le cas d'une installation servant à surveiller un centre de loisir, chaque utilisateur pourra recevoir une carte magnétique qu'il devra simplement faire lire par la balise au moment de pénétrer dans un local ou sur un terrain; cette action aura pour effet de déclencher un certain nombre d'actions sur le site (ouverture des portes, mise en fonction de l'éclairage etc..) et d'envoyer les informations nécessaires au point central. Dans ce type d'exemple, les informations concernant l'identification de l'utilisateur, informations contenues sur la piste magnétique, pourront être transmises au point central par la balise de site.For example, if the installation is used to monitor an industrial unit, an employee can go around the unit and have each site tag read that they have been asked to modify, the card bearing the adapted number. In the case of an installation used to monitor a leisure center, each user will be able to receive a magnetic card which he will simply have to read by the beacon when entering a room or a field; this action will have the effect of triggering a certain number of actions on the site (opening the doors, switching on the lighting, etc.) and sending the necessary information to the central point. In this type of example, the information concerning the identification of the user, information contained on the magnetic strip, could be transmitted to the central point by the site tag.
Bien entendu, les exemples ci-dessus ne sont pas limitatifs et l'on pourra utiliser des installations selon l'invention dans de très nombreuses autres applications, comme la surveillance et la gestion de stations de skis, de ports de plaisance, d'hôpitaux, d'hôtels, de ville petites ou moyennes, d'installations agricoles ou viticoles et de sites industriels. Ces installations pourront être installées à demeure ou encore mises en place pour une durée limitée, de manière par exemple à effectuer une campagne de mesure sur un site donné.Of course, the above examples are not limiting and it is possible to use installations according to the invention in very many other applications, such as the monitoring and management of ski resorts, marinas, hospitals , hotels, small and medium-sized towns, agricultural or wine-growing facilities and industrial sites. These installations can be permanently installed or even set up for a limited period, so as for example to carry out a measurement campaign on a given site.
La description ci-dessus est donnée à simple titre indicatif et l'on pourra choisir d'autres modes de réalisation des installations utilisant les balises décrites ci- dessus sans pour autant sortir du cadre de la présente invention. The above description is given for information only and other embodiments of the installations can be chosen using the tags described above without departing from the scope of the present invention.
