Description

DISPOSITIF DE CONTROLE ET / OU DE SURVEILLANCE UTILISANT AU MOINS UN CONTROLEUR DE TRANSMISSION. MONITORING AND / OR MONITORING DEVICE USING AT LEAST ONE TRANSMISSION CONTROLLER.
L'invention concerne, de façon générale, le secteur des technologies d'information et le contrôle ou la surveillance à distance.The invention relates generally to the information technology sector and remote control or monitoring.
Plus précisément, l'invention concerne un dispositif de contrôle et / ou de surveillance, comprenant une pluralité de périphériques, une unité centrale de contrôle, et un réseau de communication reliant l'unité centrale aux différents périphériques.More specifically, the invention relates to a control and / or monitoring device, comprising a plurality of peripherals, a central control unit, and a communication network connecting the central unit to the various peripherals.
Bien que de nombreux dispositifs connus répondent à cette définition, ces dispositifs mettent généralement en œuvre des moyens d'adressage sophistiqués, exigeant du réseau de communication des performances qui ne peuvent être obtenues qu'au prix d'une complexité relativement élevée.Although many known devices meet this definition, these devices generally use sophisticated addressing means, requiring performance from the communication network which can only be obtained at the cost of relatively high complexity.
Partant de ce constat, l'invention a pour but de proposer une technique permettant d'offrir les mêmes fonctionnalités que ces dispositifs connus, mais par la mise en œuvre de moyens simples et aujourd'hui répandus .On the basis of this observation, the invention aims to propose a technique making it possible to offer the same functionalities as these known devices, but by the implementation of simple and currently widespread means.
A cette fin, le dispositif de l'invention, par ailleurs conforme à la définition générique qu'en donne le préambule ci-dessus, est essentiellement caractérisé en ce qu'il comprend en outre un circuit électrique de sécurité adoptant sélectivement une configuration de sécurité ou une configuration d'anomalie, en ce que chaque périphérique est à chaque instant soumis à une condition qui l'affecte en totalité ou en partie, qui appartient à une pluralité de conditions possibles incluant une condition de référence, et dont ce périphérique rend sélectivement compte sous forme d'un code de contexte, et en ce que l'unité centrale de contrôle comprend au moins un premier contrôleur de transmission qui dispose, pour chaque périphérique, d'un code de référence mémorisé constitué par le code de contexte transmis par ce périphérique pour sa condition de référence, qui relève le code de contexte de chacun des périphériques par scrutation périodique de ces périphériques suivant un ordre d'adressage prédéterminé, qui opère des comparaisons un à un des codes de contexte relevés par scrutation des périphériques et des codes de référence mémorisés par lui, et qui commande un passage du circuit de sécurité de sa configuration de sécurité à sa configuration d'anomalie en réponse à la détection d'une absence d'un des codes à comparer ou d'une disparité entre les codes comparés par lui .To this end, the device of the invention, moreover conforms to the generic definition given in the preamble above, is essentially characterized in that it further comprises an electrical safety circuit selectively adopting a safety configuration or an anomaly configuration, in that each peripheral is at all times subject to a condition which affects it in whole or in part, which belongs to a plurality of possible conditions including a reference condition, and of which this peripheral device selectively reports in the form of a context code, and in that the central control unit comprises at least a first transmission controller which has, for each device, a stored reference code constituted by the context code transmitted by this device for its reference condition, which reads the context code of each of the devices by periodic scanning of these devices according to a predetermined addressing order , which performs one-to-one comparisons of the context codes detected by scanning the peripherals and the reference codes memorized by it, and which controls a passage of the security circuit from its security configuration to its anomaly configuration in response to the detection of an absence of one of the codes to be compared or of a disparity between the codes compared by him .
Dans le mode de réalisation préféré de l'invention, chaque périphérique est repéré par un code d'identification qui lui est spécifique et que ce périphérique délivre à l'unité centrale de contrôle, en tant que code de contexte, dans le cas où il se trouve dans sa condition de référence, et seulement dans ce cas.In the preferred embodiment of the invention, each peripheral is identified by an identification code which is specific to it and which this peripheral delivers to the central control unit, as context code, in the event that it is in its reference condition, and only in this case.
Il peut être utile de prévoir que l'unité centrale de contrôle comprenne un deuxième contrôleur de transmission qui dispose également, pour chaque périphérique, d'un code de référence mémorisé constitué par le code de contexte que fournit ce périphérique pour sa condition de référence, et que ce deuxième contrôleur de transmission, indépendamment du premier contrôleur de transmission, opère des comparaisons un à un des codes de contexte relevés par scrutation des périphériques et des codes de référence mémorisés par lui, et commande un passage du circuit de sécurité de sa configuration de sécurité à sa configuration d'anomalie en réponse à la détection d'une absence d'un des codes à comparer ou d'une disparité entre les codes comparés par lui .It may be useful to provide that the central control unit comprises a second transmission controller which also has, for each device, a stored reference code constituted by the context code which this device provides for its reference condition, and that this second transmission controller, independently of the first transmission controller, performs one-to-one comparisons of the context codes detected by scanning the peripherals and of the reference codes memorized by it, and controls a passage of the security circuit from its security configuration to its anomaly configuration in response to the detection of an absence of one of the codes to be compared or of a disparity between the codes compared by it.
Par exemple, chaque contrôleur de transmission comprend, en mémoire, une table fixe de codes de référence mémorisés au cours d'une phase d'installation du dispositif et une table dynamique recensant les codes de contexte relevés par scrutation des périphériques, chaque contrôleur de transmission pouvant ainsi comparer les contenus respectifs de la table fixe et de la table dynamique en remettant périodiquement à jour le contenu de la table dynamique.For example, each transmission controller includes, in memory, a fixed table of reference codes stored during a device installation phase and a dynamic table listing the context codes detected by scanning the peripherals, each transmission controller thus being able to compare the respective contents of the fixed table and the dynamic table by periodically updating the content of the dynamic table.
Les périphériques sont avantageusement alimentés en énergie électrique par l'unité centrale de contrôle à travers le réseau de communication.The peripherals are advantageously supplied with electrical energy by the central control unit through the communication network.
Par ailleurs, ce réseau peut être essentiellement constitué par un bus filaire reliant tous les périphériques à l'unité centrale.Furthermore, this network can essentially consist of a wired bus connecting all the peripherals to the central unit.
Dans sa forme la plus accomplie, le dispositif de 1 ' invention peut être conçu de manière que chaque périphérique comprenne une paire d'organes interactifs incluant un organe maître et un organe esclave associés l'un à l'autre, que le réseau de communication relie l'unité centrale aux différents organes maîtres, que, pour chaque périphérique, la condition représentée par le code de contexte soit une condition affectant l'organe esclave ou une relation entre l'organe esclave et l'organe maître de ce périphérique, et que l'organe maître de chaque périphérique alimente en énergie électrique l'organe esclave de ce périphérique et constitue une interface entre cet organe esclave et le premier contrôleur de transmission de l'unité centrale de contrôle, les organes maîtres étant par exemple alimentés en énergie électrique par le premier contrôleur à travers le réseau.In its most accomplished form, the device of the invention can be designed so that each peripheral comprises a pair of interactive members including a master member and a slave member associated with each other, than the communication network. connects the central unit to the different master organs, that, for each peripheral, the condition represented by the context code is a condition affecting the slave organ or a relationship between the slave organ and the master organ of this peripheral, and that the master organ of each peripheral supplies electrical energy to the slave organ of this peripheral and constitutes an interface between this slave organ and the first transmission controller of the central control unit, the master members being for example supplied with electrical energy by the first controller through the network.
Dans ces conditions, 1 ' organe esclave de chaque périphérique peut comprendre une étiquette électronique dans laquelle est mémorisé le code d'identification de ce périphérique, l'organe maître de ce même périphérique comprenant alors un lecteur d' étiquette électronique correspondant .Under these conditions, the slave member of each device may include an electronic label in which the identification code of this device is stored, the master member of this same device then comprising a corresponding electronic tag reader.
Chaque périphérique peut aussi comprendre un encodeur d'état produisant un signal d'état qui dépend de la condition à laquelle est soumis ce périphérique, et qui est transmis par 1 ' étiquette électronique de ce périphérique à l'organe maître correspondant, ou qui est élaboré directement par cet organe maître.Each peripheral may also include a status encoder producing a status signal which depends on the condition to which this peripheral is subjected, and which is transmitted by the electronic label of this peripheral to the corresponding master organ, or which is developed directly by this master body.
II est par exemple possible de prévoir que l'organe esclave de chaque périphérique soit mobile par rapport à l'organe maître de ce périphérique, que le signal d'état produit par l'encodeur d'état de ce périphérique soit représentatif d'une position relative de cet organe esclave par rapport à cet organe maître, et que cette position relative constitue la condition à laquelle est soumis ce même périphérique.It is for example possible to provide that the slave member of each device is movable relative to the master member of this device, that the status signal produced by the status encoder of this device is representative of a relative position of this slave member with respect to this master member, and that this relative position constitutes the condition to which this same peripheral is subjected.
A cette fin, l'encodeur d'état peut, pour chaque périphérique, comprendre au moins un aimant permanent porté par l'un des organes interactifs de ce périphérique, et un capteur de champ magnétique porté par l'autre organe interactif de ce périphérique.To this end, the status encoder may, for each device, include at least one permanent magnet carried by one of the interactive members of this peripheral, and a magnetic field sensor carried by the other interactive member of this peripheral.
Dans ce cas, il peut être judicieux de prévoir que, pour chaque périphérique, l'encodeur d'état comprenne essentiellement une paire de pistes aimantées de façon permanente espacées l'une de l'autre, portées par l'organe esclave de ce périphérique, et une paire de capteurs à effet Hall correspondants, portés par l'organe maître correspondant, que les pistes aimantées soient disposées en regard des capteurs à effet Hall correspondants pour une position relative de référence de l'organe esclave par rapport à l'organe maître, qui est unique et constitue la condition de référence, et que le signal d'état prenne au moins deux valeurs logiques différentes, selon que l'organe esclave est, ou non, dans sa position relative de référence par rapport à 1 ' organe maître .In this case, it may be wise to provide that, for each device, the status encoder essentially comprises a pair of permanently magnetized tracks spaced from one another, carried by the slave member of this device. , and a pair of corresponding Hall effect sensors, carried by the corresponding master device, that the magnetized tracks are arranged opposite the corresponding Hall effect sensors for a relative reference position of the slave device relative to the device master, which is unique and constitutes the reference condition, and that the status signal takes at least two different logical values, depending on whether or not the slave member is in its relative reference position with respect to the member master .

Comme annoncé précédemment, 1 ' invention concerne un dispositif de contrôle et / ou de surveillance, ce dispositif comprenant notamment une pluralité de périphériques tels que Pa, Pb, Pc, et Pn, une unité centrale de contrôle 4, et un réseau de communication 5 reliant l'unité centrale 4 aux différents périphériques .As previously announced, the invention relates to a control and / or monitoring device, this device comprising in particular a plurality of peripherals such as Pa, Pb, Pc, and Pn, a central control unit 4, and a communication network 5 connecting the central unit 4 to the various peripherals.
Dans le dispositif de l'invention, chacun des périphériques Pa à Pn est à chaque instant soumis à une condition, qui constitue l'objet du contrôle ou de la surveillance à assurer.In the device of the invention, each of the peripherals Pa to Pn is at all times subject to a condition, which constitutes the object of the control or monitoring to be ensured.
Pour fixer les idées, on peut par exemple imaginer que chaque périphérique peut se trouver dans un état représentatif d'une condition de fonctionnement normal, qui sera prise comme condition de référence, ou dans un état représentatif d'une condition de fonctionnement anormal, qu'il convient de détecter pour pouvoir prendre des mesures correctives adaptées .To fix ideas, we can for example imagine that each device can be in a state representative of a normal operating condition, which will be taken as a reference condition, or in a state representative of an abnormal operating condition, which must be detected in order to be able to take appropriate corrective measures.
Chaque périphérique rend compte de la condition à laquelle il est soumis sous la forme d'un code noté Ka, Kb, Kc, ou Kn, et qui est dit "code de contexte" dans la mesure où il concerne chaque périphérique considéré dans sa situation locale.Each device reports on the condition to which it is subjected in the form of a code noted Ka, Kb, Kc, or Kn, and which is said "context code" insofar as it relates to each device considered in its situation local.
Le dispositif de 1 ' invention comprend par ailleurs un circuit électrique de sécurité 6, qui est placé dans une configuration de sécurité lorsque tous les périphériques Pa à Pn sont dans leur condition de référence, ou au contraire dans une configuration d'anomalie si l'un ou plusieurs des périphériques se trouvent soumis à une condition différente de leur condition de référence.The device of the invention also comprises an electrical safety circuit 6, which is placed in a safety configuration when all the peripherals Pa to Pn are in their reference condition, or on the contrary in a fault configuration if the one or more of the peripherals are subject to a condition different from their reference condition.
Par exemple, le circuit de sécurité 6 forme une boucle continue électriquement conductrice dans sa configuration de sécurité, et se trouve interrompu dans sa configuration d'anomalie.For example, the safety circuit 6 forms an electrically conductive continuous loop in its safety configuration, and is interrupted in its fault configuration.
Pour déterminer la configuration à donner au circuit de sécurité 6, le réseau de communication 5 comprend un canal de transmission 50 reliant tous les périphériques Pa à Pn à l'unité centrale de contrôle 4, laquelle comprend elle-même un contrôleur de transmission 41, ou de préférence deux contrôleurs de transmission, 41 et 42. Bien que le canal de transmission 50 puisse être constitué par un canal radio, et bien que, par ailleurs, les périphériques Pa à Pn puissent être alimentés en énergie électrique in situ par une source décentralisée, l'hypothèse sera faite ci-après que le canal de transmission 50 est constitué par un bus filaire à travers lequel, en outre, les périphériques sont alimentés en énergie électrique, cet agencement correspondant à une mise en œuvre particulièrement avantageuse de l'invention.To determine the configuration to be given to the security circuit 6, the communication network 5 comprises a transmission channel 50 connecting all the peripherals Pa to Pn to the central control unit 4, which itself comprises a transmission controller 41, or preferably two transmission controllers, 41 and 42. Although the transmission channel 50 can be constituted by a radio channel, and although, moreover, the peripherals Pa to Pn can be supplied with electrical energy in situ by a decentralized source, the assumption will be made below that the transmission channel 50 consists of a wired bus through which, in addition, the peripherals are supplied with electrical energy, this arrangement corresponding to a particularly advantageous implementation of the invention.
Chacun des contrôleurs de transmission 41 et 42 dispose, pour chacun des périphériques Pa à Pn, d'un code de référence mémorisé tel que Ra à Rn, chaque code de référence mémorisé prenant la valeur que prend le code de contexte délivré par le périphérique correspondant pour sa condition de référence, le code de référence mémorisé Ra prenant donc la valeur du code de contexte Ka, le code de référence mémorisé Rb prenant la valeur du code de contexte Kb, etc.Each of the transmission controllers 41 and 42 has, for each of the peripherals Pa to Pn, a stored reference code such as Ra to Rn, each stored reference code taking the value taken by the context code delivered by the corresponding peripheral for its reference condition, the stored reference code Ra therefore taking the value of the context code Ka, the stored reference code Rb taking the value of the context code Kb, etc.
Les codes de référence tels que Ra, Rb, Rc, et Rn sont par exemple mémorisés, au cours d'une phase d'installation du dispositif, dans une table fixe 411 pour le contrôleur de transmission 41, et dans une table fixe 421 pour le contrôleur de transmission 42.The reference codes such as Ra, Rb, Rc, and Rn are for example stored, during a phase of installation of the device, in a fixed table 411 for the transmission controller 41, and in a fixed table 421 for the transmission controller 42.
Chacun des contrôleurs de transmission 41 et 42 scrute périodiquement chacun des périphériques Pa à Pn suivant un ordre d'adressage prédéterminé, et relève le code de contexte Ka à Kn de chaque périphérique ainsi scruté.Each of the transmission controllers 41 and 42 periodically scans each of the peripherals Pa to Pn according to a predetermined addressing order, and reads the context code Ka to Kn of each peripheral thus scanned.
Par exemple, chaque contrôleur de transmission tel queFor example, each transmission controller such as
41 et 42 comprend une unité logique d'interface correspondante, telle que 410 et 420, une table dynamique correspondante, telle que 412 et 422, et un comparateur correspondant, tel que 413 et 423.41 and 42 includes a corresponding logical interface unit, such as 410 and 420, a table corresponding dynamics, such as 412 and 422, and a corresponding comparator, such as 413 and 423.
A l'installation du dispositif, l'unité logique 410 du contrôleur de transmission 41 commande, par sa sortie d'écriture Wo, l'enregistrement des différents codes de référence Ra à Rn dans la table fixe 411, l'unité logique 420 du contrôleur de transmission 42 faisant de même pour la table fixe 421.When the device is installed, the logic unit 410 of the transmission controller 41 controls, by its write output Wo, the recording of the different reference codes Ra to Rn in the fixed table 411, the logic unit 420 of the transmission controller 42 doing the same for the fixed table 421.
Le niveau de sécurité du dispositif de 1 ' invention peut être augmenté en prévoyant que chacun des codes de référence Ra à Rn présente une structure interne satisfaisant à un algorithme prédéterminé commun à l'ensemble de ces codes de référence, que chacun des contrôleurs 41 et 42 vérifie, pendant cette phase d'installation, que la structure de chacun de ces codes de référence Ra à Rn répond bien à cet algorithme prédéterminé, et que la phase d'installation ne puisse être menée à terme avec succès que si tel est bien le cas.The security level of the device of the invention can be increased by providing that each of the reference codes Ra to Rn has an internal structure satisfying a predetermined algorithm common to all of these reference codes, that each of the controllers 41 and 42 verifies, during this installation phase, that the structure of each of these reference codes Ra to Rn responds well to this predetermined algorithm, and that the installation phase can only be successfully completed if it is well the case.
En fonctionnement, l'unité logique 410 du contrôleur de transmission 41 reçoit de chaque périphérique Pa à Pn le code de contexte Ka à Kn correspondant, et commande, par sa sortie d'écriture W, l'enregistrement de ce code dans la table dynamique 412.In operation, the logic unit 410 of the transmission controller 41 receives from each peripheral Pa to Pn the corresponding context code Ka to Kn, and commands, by its write output W, the recording of this code in the dynamic table 412.
Le comparateur 413 compare un à un les codes de contexte Ka à Kn contenus dans la table dynamique 412 aux codes de référence Ra à Rn contenus dans la table fixe 411 et informe l'unité logique 410 de tout défaut de correspondance entre les codes comparés, que ce défaut provienne de l'absence de l'un ou de plusieurs io¬ The comparator 413 compares one by one the context codes Ka to Kn contained in the dynamic table 412 with the reference codes Ra to Rn contained in the fixed table 411 and informs the logic unit 410 of any lack of correspondence between the compared codes, that this defect comes from the absence of one or more io ¬
des codes à comparer, ou d'une disparité entre les codes comparés .codes to compare, or a disparity between the compared codes.
De même, l'unité logique 420 du contrôleur de transmission 42 reçoit de chaque périphérique Pa à Pn le code de contexte Ka à Kn correspondant, et commande, par sa sortie W, l'enregistrement de ce code dans la table dynamique 422.Likewise, the logic unit 420 of the transmission controller 42 receives from each peripheral Pa to Pn the corresponding context code Ka to Kn, and controls, by its output W, the recording of this code in the dynamic table 422.
Le comparateur 423 compare un à un les codes de contexte Ka à Kn contenus dans la table dynamique 422 aux codes de référence Ra à Rn contenus dans la table fixe 421 et informe l'unité logique 420 de tout défaut de correspondance entre les codes comparés, que ce défaut provienne de l'absence de l'un ou de plusieurs des codes à comparer, ou d'une disparité entre les codes comparés .The comparator 423 compares one by one the context codes Ka to Kn contained in the dynamic table 422 with the reference codes Ra to Rn contained in the fixed table 421 and informs the logic unit 420 of any lack of correspondence between the compared codes, that this defect comes from the absence of one or more of the codes to be compared, or from a disparity between the compared codes.
Périodiquement, les unités logiques d'interface 410 et 420 effacent le contenu des tables dynamiques respectives, 412 et 422, par commande sur leurs sorties d'effacement E.Periodically, the logical interface units 410 and 420 erase the content of the respective dynamic tables, 412 and 422, by command on their erase outputs E.
Dès que le contrôleur de transmission 41 détecte un défaut de correspondance entre les codes comparés, il commande le passage du circuit de sécurité 6 de sa configuration de sécurité à sa configuration d'anomalie, cette opération étant effectuée, dans l'exemple schématiquement illustré, en interrompant le circuit de sécurité 6.As soon as the transmission controller 41 detects a correspondence fault between the compared codes, it controls the passage of the security circuit 6 from its security configuration to its abnormality configuration, this operation being carried out, in the example diagrammatically illustrated, by interrupting the safety circuit 6.
Le contrôleur de transmission 42 procède de même, et indépendamment du contrôleur de transmission 41. Bien que le code de contexte Ka à Kn, que chaque périphérique Pa à Pn délivre à l'unité centrale de contrôle 4, puisse simplement représenter la condition à laquelle est soumis ce périphérique, il peut être plus utile de prévoir que le code de contexte délivré par chaque périphérique Pa à Pn soit constitué par un code d'identification attribué à ce périphérique pour le repérer de façon spécifique, et que chaque périphérique Pa à Pn ne délivre son code d'identification à l'unité centrale 4 que s'il se trouve dans sa condition de référence .The transmission controller 42 does the same, and independently of the transmission controller 41. Although the context code Ka to Kn, which each device Pa to Pn delivers to the central control unit 4, may simply represent the condition to which this device is subjected, it may be more useful to provide that the context code delivered by each device Pa to Pn is constituted by an identification code assigned to this device to identify it in a specific way, and that each device Pa to Pn only delivers its identification code to the central unit 4 if it is in its reference condition.
Dans ce cas, si l'on note Ca, Cb, Ce, et Cn les codes d'identification respectivement attribués aux périphériques Pa, Pb, Pc, et Pn, les codes de contexte Ka, Kb, Kc, et Kn sont respectivement constitués par ces codes d'identification Ca, Cb, Ce, et Cn lorsque tous les périphériques sont dans leur condition de référence, le code de contexte Kx de tout périphérique Px qui se trouverait hors de sa condition de référence étant en revanche constitué par une absence de transmission du code d'identification Cx correspondant.In this case, if we note Ca, Cb, Ce, and Cn the identification codes respectively assigned to the peripherals Pa, Pb, Pc, and Pn, the context codes Ka, Kb, Kc, and Kn are respectively constituted by these identification codes Ca, Cb, Ce, and Cn when all the peripherals are in their reference condition, the context code Kx of any peripheral Px which would be outside of its reference condition being however constituted by an absence for transmitting the corresponding Cx identification code.
Cette situation est symboliquement illustrée sur la figure 1, dans laquelle les périphériques Pa à Pn sont tous dans leur condition de référence, à l'exception du périphérique Pb.This situation is symbolically illustrated in FIG. 1, in which the peripherals Pa to Pn are all in their reference condition, with the exception of the peripheral Pb.
Les figures 2 à 4C illustrent de façon plus précise, à titre d'exemple privilégié, des moyens particuliers permettant de mettre en œuvre le dispositif tel que précédemment décrit.FIGS. 2 to 4C illustrate more specifically, by way of a preferred example, particular means making it possible to implement the device as previously described.
Dans ce mode de réalisation détaillé, chaque périphérique tel que Pa à Pn comprend une paire d'organes interactifs, à savoir la et 2a pour le périphérique Pa, lb et 2b pour le périphérique Pb, le et 2c pour le périphérique Pc, et In et 2n pour le périphérique Pn.In this detailed embodiment, each device such as Pa to Pn comprises a pair interactive organs, namely la and 2a for the peripheral Pa, lb and 2b for the peripheral Pb, le and 2c for the peripheral Pc, and In and 2n for the peripheral Pn.
Chaque paire inclut un organe maître et un organe esclave associés l'un à l'autre, le périphérique Pa comprenant ainsi l'organe maître 2a et l'organe esclave la.Each pair includes a master member and a slave member associated with each other, the peripheral Pa thus comprising the master member 2a and the slave member 1a.
Le canal de transmission 50, en l'occurrence constitué par un bus filaire, relie l'unité centrale 4 aux différents organes maîtres tels que 2a à 2n, ces organes maîtres étant alimentés en énergie électrique à travers ce bus 50 par le contrôleur de transmission 41.The transmission channel 50, in this case constituted by a wired bus, connects the central unit 4 to the different master organs such as 2a to 2n, these master organs being supplied with electrical energy through this bus 50 by the transmission controller 41.
L'organe maître de chaque périphérique, par exemple l'organe 2a du périphérique Pa, alimente à son tour l'organe esclave correspondant, en l'occurrence l'organe la, en énergie électrique et constitue une interface de dialogue entre cet organe esclave la et le contrôleur de transmission 41 de l'unité centrale de contrôle 4.The master member of each peripheral, for example the member 2a of the peripheral Pa, in turn supplies the corresponding slave member, in this case the member 1a, with electrical energy and constitutes a dialogue interface between this slave member 1a and the transmission controller 41 of the central control unit 4.
Dans le mode de réalisation préféré de l'invention, chaque organe esclave tel que la comprend une étiquette électronique 100 (figure 2) dans laquelle est mémorisé le code d'identification Ca du périphérique correspondant Pa, et l'organe maître 2a comprend un lecteur d'étiquette électronique correspondant 200 (figure 3) .In the preferred embodiment of the invention, each slave member such as la comprises an electronic label 100 (FIG. 2) in which the identification code Ca of the corresponding peripheral Pa is stored, and the master member 2a comprises a reader corresponding electronic label 200 (Figure 3).
De façon connue en soi, l'étiquette 100 et son lecteurIn a manner known per se, the label 100 and its reader
200 sont en communication mutuelle par l'intermédiaire d'antennes radio respectives, telles que 10 et 20, le lecteur alimentant l'étiquette en énergie électrique par voie électromagnétique à travers ces antennes.200 are in mutual communication via respective radio antennas, such as 10 and 20, the reader supplying the label with electrical energy electromagnetically through these antennas.
En dehors de son antenne 10, l'étiquette 100 comprend essentiellement un circuit multifonction 11 qui est relié à l'antenne 10 et qui assure à la fois le filtrage et la distribution locale d'énergie électrique reçue sur l'antenne 10, la communication avec le lecteur 200, et plus généralement la gestion des ressources informatiques locales dont dispose cette étiquette.Apart from its antenna 10, the label 100 essentially comprises a multifunction circuit 11 which is connected to the antenna 10 and which ensures both filtering and local distribution of electrical energy received on the antenna 10, communication with reader 200, and more generally the management of local IT resources available to this label.
Le circuit multifonction 11 est doté d'une mémoire 111 dans laquelle est stocké le code d'identification Ca du périphérique correspondant Pa, et qui est conditionnellement transmis au lecteur d'étiquette 200.The multifunction circuit 11 is provided with a memory 111 in which the identification code Ca of the corresponding peripheral Pa is stored, and which is conditionally transmitted to the label reader 200.
De son côté, le lecteur 200 comprend, en plus de l'antenne 20, un circuit de communication 21, un circuit de commande 22 et un circuit d'interface réseau 23.For its part, the reader 200 comprises, in addition to the antenna 20, a communication circuit 21, a control circuit 22 and a network interface circuit 23.
Le circuit de communication 21, qui est relié à l'antenne 20, est chargé d'assurer à la fois le transfert d'énergie vers l'antenne 20 et le transfert de données à destination ou en provenance de cette antenne .The communication circuit 21, which is connected to the antenna 20, is responsible for ensuring both the transfer of energy to the antenna 20 and the transfer of data to or from this antenna.
Le circuit de communication 21 est piloté par le circuit de commande 22, qui peut lui-même dialoguer avec le circuit d'interface réseau 23.The communication circuit 21 is controlled by the control circuit 22, which can itself dialogue with the network interface circuit 23.
Le circuit d'interface réseau 23 assure quant à lui la réception de 1 ' énergie électrique véhiculée sur le bus 50, et le dialogue avec l'unité centrale 4 à travers le bus 50.The network interface circuit 23 ensures reception of the electrical energy carried on the bus 50, and the dialogue with the central unit 4 through the bus 50.
Chaque périphérique tel que Pa comprend en outre un encodeur d'état 3 par exemple formé d'un circuit d'alimentation et de mise en forme 30 porté par l'organe maître 2a, et de divers autres composants tels que 311, 312, 321, et 322 qui seront détaillés ultérieurement .Each peripheral such as Pa further comprises a status encoder 3 for example formed by a power supply and shaping circuit 30 carried by the master member 2a, and by various other components such as 311, 312, 321 , and 322 which will be detailed later.
Ce transducteur d'état 3, qui appartient au moins pour partie à l'étiquette 100, a pour fonction de produire un signal d'état, qui est noté Stat_a pour le périphérique Pa, qui dépend de la condition à laquelle est soumis ce périphérique, et qui est transmis par l'étiquette électronique 100 de ce périphérique à l'organe maître correspondant 2a, ou qui est élaboré directement par cet organe maître 2a.This state transducer 3, which belongs at least in part to the label 100, has the function of producing a status signal, which is noted Stat_a for the device Pa, which depends on the condition to which this device is subjected. , and which is transmitted by the electronic label 100 of this peripheral to the corresponding master organ 2a, or which is produced directly by this master organ 2a.
Plus précisément, le signal d'état Stat_a reflète, pour le périphérique Pa, une condition affectant l'organe esclave la ou une relation entre 1 ' organe esclave la et l'organe maître 2a de ce périphérique, cette condition étant précisément celle à laquelle est subordonnée la délivrance du code d'identification Ca en tant que code de contexte Ka.More precisely, the status signal Stat_a reflects, for the peripheral Pa, a condition affecting the slave organ la or a relationship between the slave organ la and the master organ 2a of this peripheral, this condition being precisely that at which the delivery of the identification code Ca as the context code Ka is subject.
Dans le cas où le signal d'état tel que Stat_a concerne une relation entre l'étiquette 100 et le lecteur 200, cette relation peut être constituée par une position relative de ces deux organes, comme l'illustrent les figures 4A à 4C.In the case where the status signal such as Stat_a relates to a relationship between the label 100 and the reader 200, this relationship can be constituted by a relative position of these two members, as illustrated in FIGS. 4A to 4C.
Dans ce cas, l'organe esclave la est mobile par rapport à l'organe maître 2a, et le signal d'état Stat_a est alors représentatif de la position relative adoptée à chaque instant par ces deux organes .In this case, the slave member 1a is movable relative to the master member 2a, and the status signal Stat_a is then representative of the relative position adopted at each instant by these two bodies.
Par exemple, l'encodeur d'état comprend un ou plusieurs aimants permanents, tels que 311 et 312, portés par l'un des organes de la première paire P d'organes interactifs, en l'occurrence par l'organe esclave la, et un ou plusieurs capteurs de champ magnétique, tels que 321 et 322, porté par l'autre organe de cette première paire P d'organes interactifs, en l'occurrence par l'organe maître 2a.For example, the status encoder comprises one or more permanent magnets, such as 311 and 312, carried by one of the members of the first pair P of interactive members, in this case by the slave member 1a, and one or more magnetic field sensors, such as 321 and 322, carried by the other member of this first pair P of interactive members, in this case by the master member 2a.
Les figures 2 à 4C illustrent un mode de réalisation dans lequel l'encodeur d'état 3 comprend deux pistes aimantées, 311 et 312, aimantées de façon permanente, espacées l'une de l'autre, et portées par l'organe esclave la, et deux capteurs à effet Hall correspondants, 321 et 322, portés par l'organe maître 2a.FIGS. 2 to 4C illustrate an embodiment in which the state encoder 3 comprises two magnetized tracks, 311 and 312, permanently magnetized, spaced from one another, and carried by the slave member 1a. , and two corresponding Hall effect sensors, 321 and 322, carried by the master member 2a.
Les pistes aimantées 311 et 312 sont disposées en regard des capteurs à effet Hall correspondants 321 et 322 pour l'unique position relative des organes la et 2a qu'illustre la figure 4C, cette position relative étant utilisée comme référence et constituant donc la condition de référence.The magnetic tracks 311 and 312 are arranged opposite the corresponding Hall effect sensors 321 and 322 for the single relative position of the members 1a and 2a illustrated in FIG. 4C, this relative position being used as a reference and therefore constituting the condition of reference.
Les capteurs à effet Hall 321 et 322 sont reliés au circuit 30 d'alimentation électrique et de mise en forme, qui produit le signal d'état Stat_a et qui le fournit au circuit de contrôle 22, ce signal prenant au moins deux valeurs logiques principales différentes, selon que l'organe esclave la est, ou non, dans sa position relative de référence par rapport à 1 ' organe maître 2a. En d'autres termes, quel que soit le nombre de bits servant à coder le signal d'état Stat_a, le code représentatif de ce signal commence par un bit de poids fort égal à "1" ou à "0" (ou l'inverse) selon que l'organe esclave la est, ou non, dans sa position relative de référence par rapport à l'organe maître 2a.The Hall effect sensors 321 and 322 are connected to the power supply and shaping circuit 30, which produces the status signal Stat_a and which supplies it to the control circuit 22, this signal taking at least two main logic values different, depending on whether the slave member 1a is or not, in its relative reference position with respect to the master member 2a. In other words, whatever the number of bits used to code the status signal Stat_a, the code representative of this signal begins with a most significant bit equal to "1" or to "0" (or the inverse) depending on whether the slave member 1a is or not, in its relative reference position with respect to the master member 2a.
La figure 4A représente 1 ' organe esclave la dans une position éloignée par rapport à l'organe maître 2a, c'est-à-dire dans une position dans laquelle aucun des capteurs à effet Hall 321 et 322 ne détecte une des pistes aimantées 311 et 312, et dans laquelle les antennes 10 et 20 sont trop décalées l'une par rapport à 1 ' autre pour permettre une communication entre le lecteur 200 et l'étiquette 100.FIG. 4A represents the slave member 1a in a position remote from the master member 2a, that is to say in a position in which none of the Hall effect sensors 321 and 322 detects one of the magnetized tracks 311 and 312, and in which the antennas 10 and 20 are too offset relative to one another to allow communication between the reader 200 and the label 100.
La figure 4B représente 1 ' organe esclave la dans une position dite "intermédiaire" par rapport à l'organe maître 2a, c'est-à-dire dans une position dans laquelle un seul des capteurs à effet Hall 321 et 322 détecte l'une des pistes aimantées 311 et 312, les antennes 10 et 20 pouvant en outre être éventuellement encore trop décalées 1 ' une par rapport à 1 ' autre pour permettre une communication entre le lecteur 200 et l'étiquette 100.FIG. 4B represents the slave member 1a in a so-called "intermediate" position relative to the master member 2a, that is to say in a position in which only one of the Hall effect sensors 321 and 322 detects the one of the magnetic tracks 311 and 312, the antennas 10 and 20 possibly furthermore being possibly still too offset 1 'relative to one another to allow communication between the reader 200 and the label 100.
Enfin, la figure 4C représente l'organe esclave la dans sa position de référence par rapport à 1 ' organe maître 2a, c'est-à-dire dans une position dans laquelle chacun des capteurs à effet Hall 321 et 322 détecte la piste aimantée correspondante 311 et 312, et dans laquelle les antennes 10 et 20 permettent une communication entre le lecteur 200 et l'étiquette 100. Pour les positions relatives illustrées aux figures 4A et 4B, le signal Stat_a prend une valeur telle que le code d'identification Ca n'est pas transmis à l'unité centrale 4, ce code étant en revanche transmis en tant que code de contexte Ka pour la position relative de référence illustrée à la figure 4C.
