Description
SYSTEME DE COMMUNICATION PAR RADIO DANS LE DOMAINE DES VEHICULES La présente invention se rapporte au dialogue entre les organes électriques ou électroniques d'une installation mobile ou fixe et plus particulièrement de véhicules automobiles. The present invention relates to dialogue between the electrical or electronic components of a mobile or fixed installation and more particularly of motor vehicles.
Les véhicules sont équipés de faisceaux électriques avec commande par contact et relais. Vehicles are fitted with electrical harnesses with contact and relay control.
Récemment, les équipementiers ont recherché à simplifier les faisceaux électriques de véhicules au moyen de fibres optiques ou autres systèmes de BUS ou encore, tel que décrit dans la demande de brevet publiée 2 746 946, par un système de communication binaire en faisant varier la tension présente sur un conducteur unique. Recently, equipment manufacturers have sought to simplify the electrical harnesses of vehicles by means of optical fibers or other BUS systems or, as described in published patent application 2,746,946, by a binary communication system by varying the voltage. present on a single conductor.
Le système de dialogue autonome selon l'invention propose de simplifier les systèmes existant tout en commandant les systèmes en mesurant les tensions, les courants, la présence de charges, ainsi que les défauts. The autonomous dialogue system according to the invention proposes to simplify the existing systems while controlling the systems by measuring the voltages, the currents, the presence of charges, as well as the faults.
Le systeme selon l'invention est caractérisé en ce chaque organe comporte - émetteur récepteur radio - microprocesseur de gestion et de dialogue autonome - alimentation continue et communique avec les autres organes et plus particulièrement avec l'organe de commande ondes radio modulées, par exemple par modulation ASK, FSK ou autres. Cette disposition permet ainsi de communiquer aux différents éléments électriques ou électroniques du véhicule les différents ordres de commutation de même qu'il permet d'effectuer des mesures physiques, de détecter en retour toute anomalie de fonctionnement d'un élément considéré et de les transmettre aux autres organes. The system according to the invention is characterized in that each member comprises - radio transmitter and receiver - microprocessor for autonomous management and dialogue - continuous power supply and communicates with the other members and more particularly with the radio modulated radio control member, for example by ASK, FSK or other modulation. This arrangement thus makes it possible to communicate to the various electrical or electronic elements of the vehicle the various switching orders as well as it makes it possible to carry out physical measurements, to detect in return any anomaly of operation of an element considered and to transmit them to the other organs.
Chaque organe du circuit d'émission et/ou de réception radio est modulé en fréquence et comporte un code d'identification propre, la construction du signal ' émettre est réalisée par un microprocesseur contenu dans chaque organe, le signal ensuite amplifié par un circuit électronique avant sa propagation par l'antenne à tous autres organes. Each organ of the radio transmission and / or reception circuit is frequency modulated and has its own identification code, the construction of the signal to be transmitted is carried out by a microprocessor contained in each organ, the signal then amplified by an electronic circuit. before its propagation by the antenna to all other organs.
Le microprocesseur construit de façon analogique les signaux radio à emettre et analyse les signaux radio reçus et construit une trame numérique qui est ensuite décodée afin d'obtenir les différentes données telles que le code de l'organe émetteur, code de l'organe destinataire, l'ordre à exécuter, les différentes données et paramètres et la clé de cette trame. The microprocessor constructs the radio signals to be transmitted analogically and analyzes the radio signals received and constructs a digital frame which is then decoded in order to obtain the various data such as the code of the sending organ, code of the destination organ, the order to execute, the different data and parameters and the key of this frame.
La trame numérique est reçue par tous les organes et les microprocesseurs desdits organes récepteurs comparent leur code d'identification propre à celui contenu dans la trame, de telle sorte que l'organe concerné est le seul à exécuter l'ordre émis. The digital frame is received by all the bodies and the microprocessors of said receiving bodies compare their own identification code with that contained in the frame, so that the body concerned is the only one to execute the order sent.
Si la trame numérique reçue est destinée à cet organe, le microprocesseur interne à celui-ci regarde si celle-ci n'est pas erronée. Pour ce faire, le microprocesseur calcule une clé numérique à l'aide de tous les bits contenus dans la trame reçue et la compare à la clé contenue dans la trame elle-même. Si le résultat donne la valeur zéro c'est que la trame reçue ne contient pas d'erreur de transmission. A cette étape, le microprocesseur exécute l'ordre contenu dans la trame reçue et envoie un accusé de réception à l'organe émetteur. If the digital frame received is intended for this member, the internal microprocessor thereof checks whether it is not erroneous. To do this, the microprocessor calculates a digital key using all the bits contained in the received frame and compares it to the key contained in the frame itself. If the result gives the value zero, the received frame does not contain a transmission error. At this stage, the microprocessor executes the order contained in the frame received and sends an acknowledgment of receipt to the sending unit.
Pour l'émission d'informations, l'organe construit, par le biais son microprocesseur interne, une trame numérique puis la transforme avec onde porteuse en un signal analogique. Le signal analogique ainsi obtenu est amplifié puis propagé par l'antenne à tous les autres organes et notamment à l'organe de commande ou de contrôle. For the transmission of information, the organ constructs, through its internal microprocessor, a digital frame then transforms it with carrier wave into an analog signal. The analog signal thus obtained is amplified and then propagated by the antenna to all the other organs and in particular to the command or control organ.
La trame numérique construite par le microprocesseur contient le code l'organe destinataire, le code de l'organe émetteur, l'ordre, les données, les paramètres ainsi que la clé de la trame. Par ce mode de codage, chaque organe peut connaître qui émet et qui est destinataire. The digital frame constructed by the microprocessor contains the code of the recipient unit, the code of the sending unit, the order, the data, the parameters as well as the key of the frame. By this coding mode, each organ can know who is transmitting and who is receiving.
Par ce mode de codage le nombre d'organes qu'il est ainsi possible de mettre oeuvre simultanément est quasi sans limites. By this coding mode the number of organs which it is thus possible to implement simultaneously is almost limitless.
Selon un aspect de l'invention, la mise sous tension ou hors tension d'un quelconque organe récepteur est effectuée d'une manière progressive permettant ainsi d'éviter les pics de courant lors de la commutation. Par exemple, pour un organe qui commande une ampoule de 45 watts (par exemple celle d'un phare), l'ordre d'allumage est donné de telle sorte que celle-ci s'éclaire progressivement jusqu'à illumination totale. According to one aspect of the invention, the switching on or off of any receiving member is carried out in a progressive manner thus making it possible to avoid current peaks during switching. For example, for an organ which controls a 45 watt bulb (for example that of a headlight), the lighting order is given so that it gradually lights up until complete illumination.
Selon un autre aspect de l'invention, la liaison radio du système de dialogue peut également être établie à travers un (ou plusieurs) conducteur(s) reliant tous les organes entre eux permettant ainsi d'éviter tout brouillage. According to another aspect of the invention, the radio link of the dialogue system can also be established through one (or more) conductor (s) connecting all of the members together, thus making it possible to avoid any interference.
Selon un autre aspect préférentiel de l'invention, la liaison radio du système de dialogue, dans le cas où tous les organes sont reliés à une alimentation commune, est établie à travers cette alimentation commune. Selon un autre aspect de l'invention, les commandes des eléments fonctionnels du véhicule peuvent être actionnées à distance par radio GSM satellite permettant ainsi, par exemple, d'effectuer la télémaintenance du véhicule ou de pouvoir immobiliser à distance le véhicule en cas de vol en bloquant une commande vitale au fonctionnement du moteur. According to another preferred aspect of the invention, the radio link of the dialogue system, in the case where all the organs are connected to a common power supply, is established through this common power supply. According to another aspect of the invention, the controls of the functional elements of the vehicle can be actuated remotely by satellite GSM radio, thus making it possible, for example, to perform remote maintenance of the vehicle or to be able to immobilize the vehicle remotely in the event of theft by blocking a vital command to engine operation.
D'autres buts, avantages et caractéristiques de l'invention apparaîtront à la lecture de la description de plusieurs modes de réalisation, faite, à titre non limitatif, en regard des dessins annexés où - La figure 1 représente deux organes communiquant par radio; - figure 2 représente un organe émetteur et un organe récepteur chacun comportant microprocesseur et un amplificateur électronique ; - La figure 3 un groupe d'organes de commande et d'exécution ; - figure 4 représente deux organes de commande et d'exécution où l'onde est portée par conducteur commun. Other objects, advantages and characteristics of the invention will appear on reading the description of several embodiments, given, without limitation, with reference to the appended drawings in which - FIG. 1 represents two organs communicating by radio; - Figure 2 shows a transmitting member and a receiving member each comprising microprocessor and an electronic amplifier; - Figure 3 a group of control and execution organs; - Figure 4 shows two control and execution bodies where the wave is carried by common conductor.
- La figure 5 représente un groupe d'organes de commande et d'exécution où l'onde est portée par un conducteur commun d'alimentation. - Figure 5 shows a group of control and execution members where the wave is carried by a common supply conductor.
- La figure 1 représente deux organes A, B communiquant par ondes radio modulées en fréquence à l'aide des antennes Z1, Z2, chacun des deux organes étant alimenté en tension par une source d'énergie 1 et relié à une même masse 2 - Sur la figure 2, l'organe A est, par exemple, l'organe de commande situé sur le tableau de bord du véhicule alors que l'organe B est, par exemple l'organe d'exécution qui commande un clignoteur 3 dudit véhicule. Les deux organes communiquent entre eux par ondes radio modulées en fréquence à l'aide des antennes Z1 et Z2 et sont alimentés par une source d'énergie 1 et reliés à une masse commune 2. Pour l'émission de commande, l'organe A construit, par le biais d'un microprocesseur interne P1, une trame numérique puis la transforme avec une onde porteuse en un signal analogique. Le signal analogique ainsi obtenu est amplifié par un amplificateur E1 puis propagé par l'antenne Z1 à l'organe B. - Figure 1 shows two organs A, B communicating by frequency-modulated radio waves using antennas Z1, Z2, each of the two organs being supplied with voltage by an energy source 1 and connected to the same ground 2 - In FIG. 2, the member A is, for example, the control member located on the dashboard of the vehicle whereas the member B is, for example the execution member which controls a flashing light 3 of the said vehicle . The two organs communicate with each other by frequency-modulated radio waves using the antennas Z1 and Z2 and are supplied by an energy source 1 and connected to a common ground 2. For the command emission, the organ A builds, using an internal microprocessor P1, a digital frame then transforms it with a carrier wave into an analog signal. The analog signal thus obtained is amplified by an amplifier E1 then propagated by the antenna Z1 to the organ B.
Chaque organe de commande et/ou d'exécution comporte des circuits d'émission et de réception radio qui sont modulés en fréquence. Sur ordre de commande du clignoteur par le conducteur, par exemple par la mise sous tension du contacteur K, le signal à émettre est construit par un microprocesseur P1, interne à l'organe A, puis amplifié par un circuit électronique E1 avant d'être propagé par l'antenne Z1. Le signal reçu par l'antenne Z2 de l'organe d'exécution B est alors amplifié par le circuit électronique E2 puis mis en forme le microprocesseur P2 qui traite le signal reçu et commande la mise sous tension du clignoteur 3. Each control and / or execution member comprises radio transmission and reception circuits which are frequency modulated. On a command from the driver to command the flasher, for example by switching on the contactor K, the signal to be transmitted is constructed by a microprocessor P1, internal to the member A, then amplified by an electronic circuit E1 before being propagated by the antenna Z1. The signal received by the antenna Z2 of the executing member B is then amplified by the electronic circuit E2 and then shaped the microprocessor P2 which processes the received signal and controls the powering up of the flasher 3.
La figure 3 représente groupe d'organes d'un véhicule, où, par exemple, l'organe A est l'organe de commande situé sur le tableau de bord du véhicule et les organes B, C, D sont des organes d'exécution, par exemple B pour un clignoteur 3, C pour un Klaxon 4, D pour un phare Chaque organe comporte un circuit d'émission et de réception radio qui est modulée fréquence, un circuit électronique E1, E2, E3, E4, et un microprocesseur P1, P2, P3, P4. FIG. 3 represents a group of components of a vehicle, where, for example, the component A is the control component located on the dashboard of the vehicle and the components B, C, D are execution components , for example B for a flashing light 3, C for a Horn 4, D for a headlight Each organ has a radio transmission and reception circuit which is frequency modulated, an electronic circuit E1, E2, E3, E4, and a microprocessor P1, P2, P3, P4.
Sur ordre de commande par exemple du klaxon, lorsque le conducteur du véhicule commute le contacteur microprocesseur P1 de l'organe de commande A, construit une trame numérique puis, ' travers le circuit électronique E1, la transforme avec une onde porteuse en un signal analogique. Le signal analogique ainsi obtenu est amplifié puis propagé par l'antenne Z1 à tous les autres organes B, C, D. Chaque microprocesseur de chaque organe analyse les signaux reçus et en extrait la trame numérique. Cette trame numérique est ensuite décodée, par tous les microprocesseurs, pour obtenir les différentes donnees telles que code de l'organe émetteur, code de l'organe destinataire, l'ordre à exécuter, les divers paramètres et la clé de la trame. On command order, for example from the horn, when the driver of the vehicle switches the microprocessor contactor P1 of the control unit A, builds a digital frame then, through the electronic circuit E1, transforms it with a carrier wave into an analog signal . The analog signal thus obtained is amplified then propagated by the antenna Z1 to all the other organs B, C, D. Each microprocessor of each organ analyzes the signals received and extracts the digital frame therefrom. This digital frame is then decoded, by all the microprocessors, to obtain the different data such as code of the sending organ, code of the recipient organ, the order to be executed, the various parameters and the key of the frame.
Chaque microprocesseur P2, P3, P4, vérifie si la trame reçue ne possède pas d'erreur en calculant clé numérique à l'aide de tous les bits contenus dans celle-ci et la compare à la clé contenue dans la trame elle-même. Si le résultat de cette comparaison donne la valeur zéro, c'est que la trame reçue ne contient pas d'erreur de transmission. Ensuite, si la trame est correctement reçue, chaque microprocesseur P2, P3, P4 compare leur code d'identification avec celui contenu dans la trame. Le microprocesseur P3 qui possède le meme code d'identification que celui contenu dans la trame reçue exécute l'ordre en commutant le klaxon 4 et envoie un accusé de réception à l'organe émetteur A. Each microprocessor P2, P3, P4, checks whether the received frame has no error by calculating the digital key using all the bits contained therein and compares it to the key contained in the frame itself. If the result of this comparison gives the value zero, it means that the frame received does not contain a transmission error. Then, if the frame is received correctly, each microprocessor P2, P3, P4 compares their identification code with that contained in the frame. The microprocessor P3 which has the same identification code as that contained in the received frame executes the order by switching the horn 4 and sends an acknowledgment of receipt to the transmitting member A.
Pour l'émission d'informations, l'organe C construit, par le biais de son microprocesseur interne P3, une trame numérique, puis la transforme avec une onde porteuse en un signal analogique, signal analogique ainsi obtenu est amplifié par le circuit électronique E3 puis propagé par l'antenne Z3 à tous les autres organes A, B, D. L'organe de commande A reçoit ainsi l'accusé de réception lui indiquant que le klaxon a bien été commuté et a parfaitement fonctionné et peut ainsi en informer le conducteur du véhicule par un signal déterminé. For the transmission of information, the member C constructs, by means of its internal microprocessor P3, a digital frame, then transforms it with a carrier wave into an analog signal, analog signal thus obtained is amplified by the electronic circuit E3 then propagated by the antenna Z3 to all the other members A, B, D. The control member A thus receives the acknowledgment of receipt indicating to him that the horn has indeed been switched and has worked perfectly and can thus inform the driver of the vehicle by a specific signal.
Les trames numériques ainsi construites et reçues par les microprocesseurs contiennent, le code de l'organe destinataire, le code de l'organe émetteur, l'ordre, les différentes données, les paramètres ainsi que la clé de la trame. Par ce mode de codage, tout organe peut savoir qui émet et qui est destinataire et le nombre d'organes pouvant ainsi être ' en oeuvre simultanément ne comporte quasiment pas limites. The digital frames thus constructed and received by the microprocessors contain, the code of the recipient unit, the code of the sending unit, the order, the various data, the parameters as well as the key of the frame. By this coding mode, any organ can know who transmits and who is addressee and the number of organs which can thus be used simultaneously has almost no limits.
La figure 4 représente deux organes A, B, alimentés par la même source d'énergie 1 qui communiquent ensemble leurs informations radio sur un conducteur L1 les reliant entre eux. FIG. 4 represents two organs A, B, supplied by the same energy source 1 which communicate their radio information together on a conductor L1 connecting them together.
La figure 5 représente un groupe d'organes d'un véhicule où, par exemple, l'organe est l'organe de commande situé sur le tableau de bord du véhicule et les organes B, C, D sont des organes d'exécution, par exemple B pour un clignoteur 3, C pour un klaxon 4, D pour un phare 5. Les organes représentés sont alimentés par une source d'énergie commune 1 distribuée par un conducteur commun Chaque organe comporte un circuit d'émission et de réception radio qui est modulée fréquence, un circuit électronique E1, E2, E3, E4 et un microprocesseur P1, P2, P3, P4. Sur ordre de commande, par exemple du klaxon, lorsque le conducteur du véhicule commute le contacteur le microprocesseur P1 de l'organe de commande construit une trame numérique puis, à travers le circuit électronique E1 la transforme avec une onde porteuse en un signal analogique. Le signal analogique ainsi obtenu est amplifié puis propagé par le conducteur commun L2 à tous les autres organes B, C, D. Chaque microprocesseur de chaque organe analyse les signaux reçus et en extrait la trame numérique. Cette trame numerique est ensuite décodée, par tous les microprocesseurs, pour obtenir les différentes données, telles que le code de l'organe émetteur, code de l'organe destinataire, l'ordre à exécuter, les divers paramètres et la clé de la trame. Chaque microprocesseur P2, P3, P4 compare son code d'identification avec celui contenu dans la trame. Pour ce faire, ces microprocesseurs P2, P3, P4, calculent une clé numérique à l'aide de tous les bits contenus dans la trame reçue et la compare à la clé contenue dans leur trame elle-même. Si le résultat donne la valeur zéro, c'est que la trame reçue ne contient pas d'erreur de transmission. Le microprocesseur P3 exécute l'ordre en commutant le klaxon 4 et envoie un accusé de réception à l'organe émetteur A. FIG. 5 represents a group of components of a vehicle where, for example, the component is the control component located on the dashboard of the vehicle and the components B, C, D are execution components, for example B for a flashing light 3, C for a horn 4, D for a headlight 5. The organs represented are supplied by a common energy source 1 distributed by a common conductor Each organ comprises a radio transmission and reception circuit which is frequency modulated, an electronic circuit E1, E2, E3, E4 and a microprocessor P1, P2, P3, P4. On command order, for example from the horn, when the driver of the vehicle switches the contactor the microprocessor P1 of the control unit constructs a digital frame then, through the electronic circuit E1 transforms it with a carrier wave into an analog signal. The analog signal thus obtained is amplified then propagated by the common conductor L2 to all the other organs B, C, D. Each microprocessor of each organ analyzes the signals received and extracts the digital frame therefrom. This digital frame is then decoded, by all the microprocessors, to obtain the different data, such as the code of the sending organ, code of the recipient organ, the order to be executed, the various parameters and the key of the frame. . Each microprocessor P2, P3, P4 compares its identification code with that contained in the frame. To do this, these microprocessors P2, P3, P4, calculate a digital key using all the bits contained in the received frame and compares it to the key contained in their frame itself. If the result gives the value zero, the received frame does not contain a transmission error. The microprocessor P3 executes the order by switching the horn 4 and sends an acknowledgment of receipt to the sending unit A.
Les organes A, B, C et D, alimentés par une même source d'énergie continue 1 et transportée par le fil L2, {l'autre conducteur étant la masse du châssis), peuvent ainsi communiquer ensemble leurs informations radio modulées en fréquence par ce seul fil L2. The organs A, B, C and D, supplied by the same continuous energy source 1 and transported by the wire L2, (the other conductor being the ground of the chassis), can thus communicate together their radio information modulated in frequency by this one L2 wire.
L'utilisation du ou des fils d'alimentation d'énergie commune aux organes pour transmettre les informations radio modulées en fréquence permet une grande sécurité de communication et évite les brouillages ou parasites hertziens. Cette transmission radio modulée en fréquence sur le ou fils d'alimentation d'énergie des organes ne modifie pas la tension de cette dite alimentation. La tension de cette alimentation sans effets sur la communication radio modulee en fréquence. En cas d'absence coupure de cette tension, la communication radio modulée en fréquence est toujours établie entre tous les organes. The use of the power supply wire (s) common to the organs to transmit the frequency modulated radio information allows great security of communication and avoids interference or radio interference. This frequency modulated radio transmission on the power supply wire or wires of the organs does not modify the voltage of this said supply. The voltage of this power supply with no effect on radio communication modulates in frequency. In the absence of a cut in this voltage, the radio frequency-modulated communication is always established between all the organs.
Le système de communication selon l'invention peut être utilisé dans le domaine des véhicules tels l'automobile, les deux ou trois roues, les bateaux, les avions, etc., mais aussi dans domaine de l'industrie comme moyen de communication d'informations entre organes équipant les machines industrielles. The communication system according to the invention can be used in the field of vehicles such as the automobile, two or three wheels, boats, planes, etc., but also in the field of industry as a means of communication for information between organs equipping industrial machines.
L'invention permet de commander et de contrôler tous les organes électriques ou électroniques d'un véhicule mais permet également, sans pour autant changer son principe, de commander et de contrôler des éléments électromécaniques de gestion de moteur, de suspension, de radio, ou de tout autre élément qui peut être commandé par une tension électrique. The invention makes it possible to command and control all the electrical or electronic organs of a vehicle but also allows, without changing its principle, to command and control electromechanical elements for engine management, suspension, radio, or any other element which can be controlled by an electric voltage.
