Abstract

The method involves establishing radio communication using a radio communication module (118), and receiving a reference time. A time-stamped data of a tachograph (112) is recovered, where the tachograph has a date later than the reference time ad prior to another reference time. The recovered time-stamped data is transferred to a data receiver (114), and the radio communication is terminated. An independent claim is also included for a method for receiving time-stamped data recorded in a tachograph.

Description

La présente invention concerne un procédé de transfert par communication radio de données horodatées à partir d'un chrono tachygraphe connecté à un module de communication radio, un module de communication radio adapté à la mise en oeuvre d'un tel procédé, ainsi qu'un chronotachygraphe comprenant un tel module de communication radio. L'invention concerne également un procédé de réception de données horodatées par un récepteur de données, ainsi qu'un récepteur de données adapté à la mise en oeuvre d'un tel procédé.The present invention relates to a method for transfer by radio communication of time stamped data from a tachograph chronograph connected to a radio communication module, a radio communication module adapted to the implementation of such a method, as well as a tachograph comprising such a radio communication module. The invention also relates to a method for receiving data stamped by a data receiver, as well as a data receiver adapted to the implementation of such a method.

Un véhicule, en particulier un poids lourd, est muni d'un chronotachygraphe destiné à enregistrer les données concernant l'utilisation du véhicule, en particulier le temps de conduite, de travail, de repos et à disposition. Les données sont horodatées pour permettre leur traitement ultérieur. Le chronotachygraphe est un appareil qui enregistre numériquement l'ensemble des données du véhicule dans une mémoire afin de pouvoir les restituer le moment venu.A vehicle, in particular a heavy vehicle, is provided with a tachograph for storing data relating to the use of the vehicle, in particular driving time, working time, rest time and availability. The data is time-stamped for later processing. The tachograph is a device that digitally records all the vehicle data in a memory so that it can be returned when the time comes.

La législation européenne oblige à un rapatriement régulier des données contenues dans la mémoire du chronotachygraphe vers un centre de gestion, comme par exemple, le siège social de l'entreprise de transport où les données horodatées sont conservées afin de les tenir à disposition des autorités de contrôle pendant un temps conforme au règlement européen N°1360/2002 du 13 juin 2002 . Celui-ci, et en particulier son annexe 1B, spécifie les exigences relatives à la fréquence de rapatriement et à la conservation des données relatives aux camions et aux conducteurs.European legislation requires regular repatriation of the data contained in the tachograph's memory to a management center, such as, for example, the head office of the transport undertaking where the time stamped data are kept in order to keep them at the disposal of the authorities. control for a time consistent with the regulations European Union N ° 1360/2002 of June 13, 2002 . This, and in particular Annex 1B, specifies the requirements for the frequency of repatriation and retention of data relating to trucks and drivers.

On connaît un module de communication radio qui se connecte à un chronotachygraphe afin de télécharger les données contenues dans la mémoire du chronotachygraphe.A radio communication module is known which connects to a tachograph in order to download the data contained in the memory of the tachograph.

Le chronotachygraphe conserve en mémoire environ un an de données horodatées. Le module de communication radio est connecté au chronotachygraphe à un instant 't' et il récupère les données horodatées qui se situent entre un certain nombre de jours et cet instant t. Par exemple, le module de communication radio récupère les données horodatées relatives aux 90 jours qui se sont écoulés avant l'instant t. Le module de communication radio comprend un moyen de communication radio permettant de transférer, par communication radio, l'ensemble des données qui ont été préalablement téléchargées à partir de la mémoire du chronotachygraphe vers le centre de gestion via un outil informatique de collecte puis de transfert. Les procédures à mettre alors en place sont complexes (centre de vidage à mettre en oeuvre), consommatrices des ressources humaines et ne permettent pas une optimisation des volumes de données à gérer.The tachograph keeps in memory about one year of time stamped data. The radio communication module is connected to the tachograph at a time 't' and it retrieves the time stamped data which are between a certain number of days and this instant t. For example, the radio communication module retrieves the time stamped data relating to the 90 days that elapsed before time t. The radio communication module comprises a radio communication means making it possible to transfer, by radio communication, all the data that have been previously downloaded from the tachograph memory to the management center via a data collection and transfer tool. . The procedures to be put in place are complex (emptying center to be human resource users and do not allow optimization of the volumes of data to be managed.

Ce procédé de transfert de données présente de nombreux désavantages. Par exemple, il arrive fréquemment que les données qui sont transférées à l'instant t se chevauchent avec les données qui ont été transférées lors de transferts antérieurs, créant ainsi des données redondantes et le transfert de données n'est alors pas optimisé. Il peut également arriver que le véhicule ne rentre pas à sa base durant ce délai (dans l'exemple: 90 jours). L'utilisation du module de communication de l'état de la technique permet alors de récupérer les données vieilles d'au plus 90 jours, mais les données antérieures ne peuvent pas être récupérées.This data transfer method has many disadvantages. For example, data that is transferred at time t frequently overlaps with data that has been transferred in previous transfers, creating redundant data, and data transfer is not optimized. It may also happen that the vehicle does not return to its base during this time (in the example: 90 days). The use of the prior art communication module then makes it possible to recover the data older than 90 days, but the previous data can not be recovered.

Les données relatives au conducteur sont enregistrées sur une carte à puce qui s'insère dans le chronotachygraphe du véhicule que le conducteur conduit. Ces données relatives au conducteur doivent être rapatriées régulièrement conformément à la réglementation européenne N°1360/2002 du 13 juin 2002. Ces données peuvent aussi servir à l'établissement de la feuille de paie du conducteur. Le rapatriement des données relatives au conducteur s'effectue actuellement par retrait de la carte du chronotachygraphe et insertion de celle-ci dans une borne spécialisée. Une telle procédure est fastidieuse pour le conducteur et coûteuse pour l'entreprise, car le véhicule doit être régulièrement détourné de son trajet pour effectuer ce rapatriement.The data relating to the driver is recorded on a smart card that fits into the tachograph of the vehicle that the driver drives. Driver data must be repatriated regularly in accordance with the regulations European Commission N ° 1360/2002 June 13, 2002. This data can also be used to establish the driver's payroll. The repatriation of data relating to the driver is currently done by removing the card from the tachograph and inserting it into a specialized terminal. Such a procedure is tedious for the driver and expensive for the company, because the vehicle must be routinely diverted from its path to perform this repatriation.

Un objet de la présente invention est de proposer un procédé de transfert par communication radio de données horodatées enregistrées dans un chronotachygraphe vers un récepteur de données et un procédé de réception par un récepteur de données, de données horodatées enregistrées dans un chronotachygraphe, qui ne présentent pas les inconvénients de l'art antérieur et qui en particulier optimisent la durée nécessaire au transfert des données du chronotachygraphe et qui, éventuellement, permettent également le rapatriement des données relatives au conducteur.An object of the present invention is to propose a method of transfer by radio communication of timestamped data recorded in a tachograph to a data receiver and a method of reception by a data receiver of timestamped data recorded in a tachograph, which does not present not the disadvantages of the prior art and in particular optimize the time required for the transfer of data from the tachograph and which, possibly, also allow the repatriation of data relating to the driver.

La Fig. 1 représente un système de communication 100 qui comprend un chronotachygraphe 112, un premier module de communication radio 118, un récepteur de données 114 et un deuxième module de communication radio 126.The Fig. 1 represents a communication system 100 which comprises a tachograph 112, a first radio communication module 118, a data receiver 114 and a second radio communication module 126.

Le chronotachygraphe 112 est disposé à l'intérieur d'un véhicule 108 et il enregistre les différents évènements représentatifs du fonctionnement du véhicule 108. Les différents évènements sont enregistrés dans une mémoire du chronotachygraphe 112 sous forme de données horodatées qui doivent être transmises soit à une administration de contrôle, soit à un centre de gestion.The tachograph 112 is disposed inside a vehicle 108 and records the various events representative of the operation of the vehicle 108. The various events are recorded in a memory of the tachograph 112 in the form of time stamped data which must be transmitted either to a control administration, either to a management center.

Le chronotachygraphe 112 comprend un boîtier 116 à l'intérieur duquel sont disposés les éléments nécessaires à son fonctionnement. Le chronotachygraphe 112 comprend entre autre un lecteur de carte d'un premier type 122 et un lecteur de carte d'un deuxième type 124, qui sont avantageusement identiques.The tachograph 112 comprises a housing 116 inside which are arranged the elements necessary for its operation. The tachograph 112 includes among others a card reader of a first type 122 and a card reader of a second type 124, which are advantageously identical.

Le chronotachygraphe 112 est connecté au premier module de communication radio 118 muni d'une antenne 120 qui, dans le mode de réalisation représenté, est extérieure. La connexion entre le chronotachygraphe 112 et le premier module de communication radio 118 peut être réalisée par toutes sortes de connecteurs, mais qui est de préférence réalisée par la liaison série en façade avant du chronotachygraphe dont les spécifications électriques et le protocole de communication sont décrites dans l'Annexe 1B de la réglementation européenne N°1360/2002 du 13 juin 2002. Le premier module de communication radio 118 est ainsi connecté au chronotachygraphe 112 par l'intermédiaire d'un câble 134.The tachograph 112 is connected to the first radio communication module 118 provided with an antenna 120 which, in the embodiment shown, is external. The connection between the tachograph 112 and the first radio communication module 118 can be achieved by all kinds of connectors, but which is preferably performed by the serial link on the front panel of the tachograph whose electrical specifications and the communication protocol are described in Schedule 1B of the Regulations European Commission N ° 1360/2002 June 13, 2002. The first radio communication module 118 is thus connected to the tachograph 112 by means of a cable 134.

Dans un autre mode de réalisation qui n'est pas représenté sur les figures, le premier module de communication radio 118 et le chronotachygraphe 112 forment un seul appareil. La réalisation d'un seul appareil comprenant le chronotachygraphe 112 et le premier module de communication radio 118 évite d'avoir à connecter ce dernier pour réaliser les transferts de données, d'autant plus que les connecteurs peuvent être détériorés, empêchant ainsi les transferts.In another embodiment which is not shown in the figures, the first radio communication module 118 and the tachograph 112 form a single device. The realization of a single device comprising the tachograph 112 and the first radio communication module 118 avoids having to connect it to perform data transfers, especially since the connectors can be damaged, thus preventing transfers.

La connexion permanente du premier module de communication radio 118 au chronotachygraphe 112 est possible sans altérer le bon fonctionnement de ce dernier.The permanent connection of the first radio communication module 118 to the tachograph 112 is possible without affecting the proper functioning of the latter.

Dans un mode de réalisation particulier, le lecteurs de carte du premier type 122 est adapté à recevoir une carte d'identification de l'entreprise de transport à laquelle appartient le véhicule 108 et le lecteur de carte du deuxième type 124 est adapté à recevoir une carte d'identification du conducteur du véhicule 108.In a particular embodiment, the card reader of the first type 122 is adapted to receive an identification card of the transport company to which vehicle 108 and the card reader of the second type 124 is adapted to receive an identification card of the driver of the vehicle 108.

Le récepteur de données 114 est disposé dans une enceinte 110 qui peut représenter un bureau de l'administration de contrôle ou du centre de gestion. Dans le mode de réalisation de l'invention représenté à la Fig. 1, le récepteur de données 114 comprend un module de traitement 128.The data receiver 114 is disposed in an enclosure 110 which may represent an office of the control administration or the management center. In the embodiment of the invention shown in Fig. 1 , the data receiver 114 comprises a processing module 128.

La communication radio entre le premier module de communication radio 118 du chronotachygraphe 112 et le récepteur de données 114 s'effectue à travers un réseau de communication 106. Le réseau de communication radio 106 peut être tous types de réseaux de télécommunications mobiles, par exemple du type GSM ("Système mondial de communications mobiles" c'est-à-dire en anglais "Global System for Mobile Communications"), GPRS ("Service général de radiocommunication en mode paquet", c'est-à-dire en anglais "General Packet Radio Service"), UMTS ("Système universel de télécommunications mobiles" c'est-à-dire en anglais "Universal Mobile Telecommunications System"), WiFi ("Ethernet sans fil" ou en Anglais "Wireless Fidelity") ou autres.The radio communication between the first radio communication module 118 of the tachograph 112 and the data receiver 114 is effected through a communication network 106. The radio communication network 106 may be any type of mobile telecommunications network, for example type GSM ("Global System for Mobile Communications" ie "Global System for Mobile Communications"), GPRS ("General Service Packet Radio", that is to say in English " General Packet Radio Service "), UMTS (" Universal Mobile Telecommunications System "), WiFi (" Wireless Ethernet "or" Wireless Fidelity ") or other .

Dans le mode de réalisation de la Fig. 1, le réseau de communication radio 106 comprend, entre autre, le deuxième module de communication radio 126. Le deuxième module de communication radio 126 est connecté au récepteur de données 114 par l'intermédiaire d'un réseau de télécommunication filaire 130.In the embodiment of the Fig. 1 the radio communication network 106 comprises, among others, the second radio communication module 126. The second radio communication module 126 is connected to the data receiver 114 via a wired telecommunication network 130.

Dans un autre mode de réalisation de l'invention, en particulier dans le cas où le réseau de communication 106 est un réseau WiFi, le deuxième module de communication radio 126 peut être intégré au récepteur de données 114.In another embodiment of the invention, in particular in the case where the communication network 106 is a WiFi network, the second radio communication module 126 can be integrated with the data receiver 114.

La Fig. 2 représente le schéma bloc du chronotachygraphe 112 qui comprend un processeur 202 relié par l'intermédiaire d'un bus de données à une mémoire volatile 204 et à une mémoire non volatile 206. Le processeur 202 est connecté à différents capteurs par l'intermédiaire de lignes de connexion 208 dont une seule est représentée pour des facilités de visualisation, ainsi qu'au premier module de communication radio 118. Le processeur 202 est connecté au lecteur de cartes du premier type 122 et au lecteur de carte du deuxième type 124 afin de récupérer les informations contenues dans les cartes et d'enregistrer des informations dans les cartes.The Fig. 2 represents the block diagram of the tachograph 112 which comprises a processor 202 connected via a data bus to a volatile memory 204 and a non-volatile memory 206. The processor 202 is connected to different sensors via lines 208 of which only one is shown for ease of viewing, and the first radio communication module 118. The processor 202 is connected to the card reader of the first type 122 and the card reader of the second type 124 to recover the information contained in the cards and to record information in the cards.

La mémoire volatile 204 peut être du type mémoire vive, disque dur ou autre et elle permet d'enregistrer les données horodatées recueillies par le processeur 202. La mémoire non volatile 206 peut être du type mémoire morte et contient, entre autres, les instructions nécessaires à l'exécution des procédés de transfert qui seront décrits ultérieurement.The volatile memory 204 can be of the RAM, hard disk or other type and it makes it possible to record the time stamped data collected by the processor 202. The non-volatile memory 206 can be of the read-only memory type and contains, among other things, the instructions necessary to carry out the transfer processes which will be described later.

Le fonctionnement général du chronotachygraphe 112 est alors le suivant. Les différents capteurs envoient des données au processeur 202 par l'intermédiaire des lignes de connexion 208. Le processeur 202 date ces données et les sauvegarde dans la mémoire volatile 204. Lorsque des données horodatées doivent être transférées vers le récepteur de données 114, le processeur 202 récupère les données à transférer dans la mémoire volatile 204 et les envoie vers le premier module de communication 118 à partir duquel elles sont envoyées vers le récepteur de données 114.The general operation of the tachograph 112 is then as follows. The different sensors send data to the processor 202 via the connection lines 208. The processor 202 dates this data and saves them in the volatile memory 204. When time stamped data has to be transferred to the data receiver 114, the processor 202 retrieves the data to be transferred into the volatile memory 204 and sends them to the first communication module 118 from which they are sent to the data receiver 114.

La Fig. 3 représente le schéma bloc du récepteur de données 114 qui comprend un processeur 302 relié au deuxième module de communication radio 126, à une mémoire volatile 304 et à une mémoire non volatile 306. Le récepteur de données 114 sera dans notre cas un ordinateur connecté à une base de données.The Fig. 3 represents the block diagram of the data receiver 114 which comprises a processor 302 connected to the second radio communication module 126, a volatile memory 304 and a non-volatile memory 306. The data receiver 114 will in this case be a computer connected to a database.

La mémoire volatile 304 peut être du type mémoire vive, disque dur ou autre et elle permet d'enregistrer les données horodatées reçues par le processeur 302 à travers le deuxième module de communication 126. Les données horodatées sont de préférence sauvegardées sous forme d'une base de données. La mémoire non volatile 306 peut être du type mémoire morte et contient, entre autres, les instructions nécessaires à l'exécution des procédés de réception qui seront décrits ultérieurement.The volatile memory 304 may be of the RAM, hard disk or other type and it makes it possible to record the time stamped data received by the processor 302 through the second communication module 126. The time stamped data are preferably saved in the form of a database. The non-volatile memory 306 may be of the read-only memory type and contains, inter alia, the instructions necessary for carrying out the reception methods which will be described later.

Le fonctionnement général du récepteur de données 114 est alors le suivant. Le deuxième module de communication 126 reçoit les données horodatées provenant du chronotachygraphe 112 et ces données horodatées sont récupérées par le processeur 302. Le processeur 302 transfère ensuite ces données horodatées vers la mémoire volatile 304 où elles sont stockées en attendant d'être traitées.The general operation of the data receiver 114 is then as follows. The second communication module 126 receives the time stamped data from the tachograph 112 and this time stamped data is retrieved by the processor 302. The processor 302 then transfers this time stamped data to the volatile memory 304 where it is stored while waiting to be processed.

La Fig. 4 représente un exemple d'occupation de la mémoire du chronotachygraphe 112. L'axe des abscisses représente le temps 't'. Les références ta, tb, tc et td représentent des instants entre lesquels sont enregistrées les données.The Fig. 4 represents an example of occupancy of the memory of the tachograph 112. The abscissa axis represents the time 't'. The references ta, tb, tc and td represent moments between which the data are recorded.

Les deux instants consécutifs ta et tb définissent un intervalle de temps 402a. Les deux instants consécutifs tb et tc définissent un intervalle de temps 402b. Les deux instants consécutifs tc et td définissent un intervalle de temps 402c. Dans chacun de ces intervalles 402a, 402b et 402c sont enregistrées des données à transférer vers le récepteur de données 114.The two consecutive instants ta and tb define a time interval 402a. The two consecutive instants tb and tc define a time interval 402b. The two consecutive instants tc and td define a time interval 402c. In each of these intervals 402a, 402b and 402c are recorded data to be transferred to the data receiver 114.

Le chronotachygraphe 112 est généralement en mode attente, c'est-à-dire qu'il ne cherche pas à transférer ses données horodatées qui sont stockées dans sa mémoire volatile 204. Lorsque l'utilisateur désire transférer les données horodatées, il fait passer le chronotachygraphe 112 en mode émission, qui est le mode dans lequel le chronotachygraphe 112 cherche à transférer ses données horodatées. Le passage du mode attente au mode émission peut se faire, par exemple, par un bouton poussoir du chronotachygraphe 112, ou comme cela est expliqué ci-après, par l'introduction d'une carte dans l'un des lecteurs de carte 122, 124 du chronotachygraphe 112.The tachograph 112 is generally in standby mode, that is, it does not attempt to transfer its time stamped data stored in its memory When the user wishes to transfer the time-stamped data, he switches the tachograph 112 into transmission mode, which is the mode in which the tachograph 112 seeks to transfer its time-stamped data. The transition from the waiting mode to the transmission mode can be done, for example, by a push button of the tachograph 112, or as explained below, by the introduction of a card in one of the card readers 122, 124 of the tachograph 112.

Dans un mode de réalisation de l'invention, le principe de fonctionnement général du système de communication 100 est le suivant:

  • le premier module de communication radio 118 vérifie que le chronotachygraphe 112 est passé dans le mode d'émission et il procède alors à l'établissement de la communication radio avec le deuxième module 126 qui entre alors en communication avec le récepteur de données 114;
  • lorsque la communication entre le chronotachygraphe 112 et le récepteur de données 114 est établie, le récepteur de données 114 envoie au premier module de communication radio 118, un premier instant de référence ta, tb, tc;
  • après réception de cet instant de référence ta, tb, tc, le premier module de communication radio 118 récupère les données horodatées enregistrées dans le chronotachygraphe 112 qui ont une date postérieure au premier instant de référence ta, tb, tc;
  • les données horodatées ainsi récupérées sont alors transférées vers le récepteur de données 114;
  • après quoi, la communication est arrêtée.
In one embodiment of the invention, the general operating principle of the communication system 100 is as follows:
  • the first radio communication module 118 verifies that the tachograph 112 has passed into the transmission mode and then proceeds to establish the radio communication with the second module 126 which then enters into communication with the data receiver 114;
  • when the communication between the tachograph 112 and the data receiver 114 is established, the data receiver 114 sends to the first radio communication module 118 a first reference time ta, tb, tc;
  • after receiving this reference time ta, tb, tc, the first radio communication module 118 retrieves the time stamped data recorded in the tachograph 112 which has a date after the first reference time ta, tb, tc;
  • the time stamped data thus recovered are then transferred to the data receiver 114;
  • after which, the communication is stopped.

Dans un autre mode de réalisation de l'invention, le premier instant de référence ta, tb, tc est envoyé par le récepteur de données 114 au premier module de communication radio 118 à la fin d'un transfert antérieur. Ce premier instant de référence ta, tb, tc est alors mémorisé par le premier module de communication radio 118. Le principe de fonctionnement général du système de communication 100 est alors le suivant:

  • le premier module de communication radio 118 vérifie que le chronotachygraphe 112 est passé dans le mode d'émission et il procède alors à l'établissement de la communication radio avec le deuxième module 126 qui entre alors en communication avec le récepteur de données 114;
  • lorsque la communication entre le chronotachygraphe 112 et le récepteur de données 114 est établie, le premier module de communication radio 118 récupère les données horodatées enregistrées dans le chronotachygraphe 112 qui ont une date postérieure au premier instant de référence ta, tb, tc;
  • les données horodatées ainsi récupérées sont alors transférées vers le récepteur de données 114;
  • après quoi, la communication est arrêtée.
In another embodiment of the invention, the first reference time ta, tb, tc is sent by the data receiver 114 to the first radio communication module 118 at the end of a previous transfer. This first reference time ta, tb, tc is then stored by the first radio communication module 118. The general operating principle of the communication system 100 is then as follows:
  • the first radio communication module 118 verifies that the tachograph 112 has passed into the transmission mode and then proceeds to establish the radio communication with the second module 126 which then enters into communication with the data receiver 114;
  • when the communication between the tachograph 112 and the data receiver 114 is established, the first radio communication module 118 retrieves the time stamped data recorded in the tachograph 112 which has a date after the first reference time ta, tb, tc;
  • the time stamped data thus recovered are then transferred to the data receiver 114;
  • after which, the communication is stopped.

La différence entre les deux modes de réalisation décrit ci-dessus réside dans le moment où est reçu le premier instant de référence ta, tb, tc.The difference between the two embodiments described above lies in the moment when the first reference instant ta, tb, tc is received.

L'établissement de la communication peut se faire par composition du numéro d'appel du récepteur de données 114 par le premier module de communication 118 (ou bien par adressage d'une adresse IP (Internet Protocol) et être suivi de l'envoi d'un message d'acquittement du récepteur de données 114 vers le premier module de communication 118.The establishment of the communication can be done by dialing the number of the data receiver 114 by the first communication module 118 (or by addressing an IP address (Internet Protocol) and be followed by the sending of an acknowledgment message of the data receiver 114 to the first communication module 118.

L'instant de référence ta, tb, tc est choisi par le récepteur de données 114 en fonction des données qu'il a déjà reçues et stockées dans la base de données. Par exemple, si au cours d'un transfert antérieur, l'ensemble des données horodatées qui ont une date antérieure à tb ont été transmises avec succès, c'est-à-dire les données de l'intervalle 402a, les prochaines données horodatées à transférer appartiennent à l'intervalle 402b et l'instant de référence envoyé aura la valeur de tb.The reference time ta, tb, tc is chosen by the data receiver 114 according to the data that it has already received and stored in the database. For example, if during a previous transfer, the set of time-stamped data that has a date before tb has been transmitted successfully, that is, the data of the interval 402a, the next data stamped to transfer belong to the interval 402b and the reference time sent will have the value of tb.

Le premier module de communication 118 pourra alors télécharger les données du chronotachygraphe 112 et transférer uniquement les données horodatées dont la date sera postérieure à l'instant de référence. Dans l'exemple précédent, seules les données des intervalles 402b et 402c seront transférées contrairement à un chronotachygraphe de l'état de la technique qui, en cas de coupure de la communication, transfère l'ensemble des données de sa mémoire, c'est-à-dire dans l'exemple, les données horodatées dont la date est comprise dans les 90 jours précédents.The first communication module 118 can then download the data from the tachograph 112 and transfer only the time stamped data whose date will be later than the reference time. In the previous example, only the data of the intervals 402b and 402c will be transferred contrary to a tachograph of the state of the art which, in the event of communication failure, transfers all the data from its memory, this is in the example, the date stamped data whose date is within the previous 90 days.

Le fonctionnement du système de communication 100 permet ainsi de réduire le temps de transfert des données horodatées du chronotachygraphe 112 vers le récepteur de données 114 en ne transférant que les données horodatées qui n'ont pas déjà été transférées antérieurement. Le fonctionnement du système de communication 100 permet aussi d'assurer la continuité des données sauvegardées dans la base de données du récepteur de données 114 en permettant de transférer les données horodatées qui sont manquantes dans la base de données.The operation of the communication system 100 thus makes it possible to reduce the time of transfer of the time-stamped data of the tachograph 112 to the data receiver 114 by transferring only the time-stamped data which have not already been transferred previously. The operation of the communication system 100 also makes it possible to ensure the continuity of the data saved in the database of the data receiver 114 by making it possible to transfer the time-stamped data that is missing in the database.

Le principe de fonctionnement de l'invention va maintenant être détaillé à l'aide des Figs. 5 et 6 qui représentent respectivement un algorithme de fonctionnement du premier boîtier de communication 118 relié au chronotachygraphe 112 et un algorithme de fonctionnement du récepteur de données 114.The operating principle of the invention will now be detailed using the Figs. 5 and 6 which respectively represent an operating algorithm of the first communication box 118 connected to the tachograph 112 and an operating algorithm of the data receiver 114.

La Fig. 5 représente l'algorithme d'un procédé de transfert implémenté dans le premier boîtier de communication 118. Le procédé de transfert par communication radio de données horodatées enregistrées dans le chronotachygraphe 112 vers le récepteur de données 114, comprend les étapes effectuées par le premier boîtier de communication 118:

  • d'établissement 502 de la communication radio;
  • de réception 512 du premier instant de référence ta, tb, tc;
  • de récupération 518 des données horodatées du chronotachygraphe 112 qui ont une date postérieure au premier instant de référence ta, tb, tc;
  • de transfert 514 vers le récepteur de données 114, des données horodatées ainsi récupérées; et
  • d'arrêt de la communication 516.
The Fig. 5 represents the algorithm of a transfer method implemented in the first communication box 118. The method of transfer by radio communication of time stamped data recorded in the tachograph 112 to the data receiver 114, comprises the steps performed by the first communication box. communication 118:
  • establishment 502 of the radio communication;
  • receiving 512 of the first reference time ta, tb, tc;
  • recovering 518 the timestamped data of the tachograph 112 which have a date after the first reference time ta, tb, tc;
  • transfer 514 to the data receiver 114, time-stamped data thus recovered; and
  • stopping communication 516.

Comme cela a été expliqué ci-dessus, l'étape de réception 512 peut s'effectuer à la fin d'un processus de transfert antérieur et le procédé de transfert par communication radio de données horodatées enregistrées dans le chronotachygraphe 112 vers le récepteur de données 114, comprend alors les étapes effectuées par le premier boîtier de communication 118:

  • d'établissement 502 de la communication radio;
  • de récupération 518 des données horodatées du chronotachygraphe 112 qui ont une date postérieure au premier instant de référence ta, tb, tc qui a été reçu antérieurement;
  • de transfert 514 vers le récepteur de données 114, des données horodatées ainsi récupérées;
  • de réception d'un premier instant de référence ta, tb, tc, qui sera utilisé au cours d'un processus de transfert ultérieur; et
  • d'arrêt de la communication 516.
As explained above, the reception step 512 can be carried out at the end of an earlier transfer process and the method of transfer by radio communication of timestamped data recorded in the tachograph 112 to the data receiver 114, then comprises the steps performed by the first communication box 118:
  • establishment 502 of the radio communication;
  • recovering 518 the time-stamped data of the tachograph 112 which has a date after the first reference time ta, tb, tc which has been received previously;
  • transfer 514 to the data receiver 114, time-stamped data thus recovered;
  • receiving a first reference time ta, tb, tc, which will be used during a subsequent transfer process; and
  • stopping communication 516.

La Fig. 6 représente l'algorithme d'un procédé de réception implémenté dans le récepteur de données 114. Le procédé de réception, par le récepteur de données 114, de données horodatées enregistrées dans le chronotachygraphe 112, comprend les étapes effectuées par le récepteur de données 114:

  • de réception 602 de la demande d'établissement d'une communication;
  • d'émission 612 du premier instant de référence ta, tb, te;
  • de réception 614 des données horodatées qui ont une date postérieure au premier instant de référence ta, tb, tc, en provenance du chronotachygraphe 112; et
  • d'arrêt de la communication 616.
The Fig. 6 represents the algorithm of a reception method implemented in the data receiver 114. The method of reception, by the data receiver 114, of timestamped data recorded in the tachograph 112, comprises the steps performed by the data receiver 114:
  • receiving 602 of the request to establish a call;
  • 612 transmission of the first reference time ta, tb, te;
  • receiving 614 timestamped data which has a date after the first reference time ta, tb, tc, from the tachograph 112; and
  • stopping communication 616.

Comme cela a été expliqué ci-dessus, l'étape d'émission du premier instant de référence ta, tb, tc peut s'effectuer à la fin du processus de réception antérieur, c'est-à-dire lorsque la réception des données horodatées de ce processus antérieur a été confirmée.As explained above, the transmission step of the first reference time ta, tb, tc can be carried out at the end of the previous reception process, that is to say when the reception of the data timestamps of this previous process was confirmed.

Le procédé de réception, par le récepteur de données 114, de données horodatées enregistrées dans le chronotachygraphe 112, comprend alors les étapes effectuées par le récepteur de données 114:

  • de réception 602 de la demande d'établissement d'une communication;
  • de réception 614 des données horodatées qui ont une date postérieure au premier instant de référence ta, tb, tc, en provenance du chronotachygraphe 112;
  • d'émission du premier instant de référence ta, tb, tc; et
  • d'arrêt de la communication 616.
The method of reception, by the data receiver 114, of timestamped data recorded in the tachograph 112, then comprises the steps performed by the data receiver 114:
  • receiving 602 of the request to establish a call;
  • receiving 614 timestamped data which has a date after the first reference time ta, tb, tc, from the tachograph 112;
  • transmitting the first reference moment ta, tb, tc; and
  • stopping communication 616.

La demande d'établissement de la communication provient du chronotachygraphe 112 et elle a été transmise à travers le premier module de communication 118 et le deuxième module de communication 126.The call set-up request originates from the tachograph 112 and has been transmitted through the first communication module 118 and the second communication module 126.

Il est possible que le transfert des données ne puisse pas être réalisé pendant un certain intervalle de temps. Par exemple, le chronotachygraphe 112 a pu effectuer correctement un premier transfert correspondant à un premier intervalle de temps 402a, mais un deuxième transfert correspondant à un deuxième intervalle de temps 402b n'a pas pu être effectué correctement, alors qu'un troisième transfert correspondant à un troisième intervalle de temps 402c a réussi. Lors d'une tentative ultérieure de transfert, le récepteur de données 114 envoie alors un deuxième instant de référence (ici: tc), de préférence en même temps que le premier instant de référence (ici: tb). Le premier module de communication 118 transfère alors les données dont la date est comprise entre le premier instant de référence et le deuxième instant de référence.It is possible that data transfer can not be performed for a certain period of time. For example, the tachograph 112 could correctly perform a first transfer corresponding to a first time interval 402a, but a second transfer corresponding to a second time interval 402b could not be performed correctly, whereas a third transfer corresponding at a third time interval 402c succeeded. In a subsequent transfer attempt, the data receiver 114 then sends a second reference time (here: tc), preferably at the same time as the first reference time (here: tb). The first communication module 118 then transfers the data whose date is between the first reference time and the second reference time.

En d'autres termes, au cours de l'étape de réception 512, le premier module de communication 118 reçoit le deuxième instant de référence tb, tc, td, et au cours de l'étape de récupération 518, le premier module de communication 118 récupère les données horodatées qui ont une date postérieure au premier instant de référence ta, tb, tc et antérieure au deuxième instant de référence tb, tc, td. Au cours de l'étape de transfert 514, l'ensemble de ces données horodatées est transféré.In other words, during the reception step 512, the first communication module 118 receives the second reference time tb, tc, td, and during the recovery step 518, the first communication module 118 recovers the timestamped data that has a date after the first reference time ta, tb, tc and earlier than the second reference time tb, tc, td. During the transfer step 514, all of these time stamped data is transferred.

De la même manière, pour le récepteur de données 114, au cours de l'étape d'émission 612, le récepteur de données 114 émet le deuxième instant de référence tb, tc, td, et au cours de l'étape de réception 614, le récepteur de données 114 reçoit les données horodatées qui ont une date postérieure au premier instant de référence ta, tb, tc et antérieure au deuxième instant de référence tb, tc, td.Similarly, for the data receiver 114, during the transmission step 612, the data receiver 114 transmits the second reference time tb, tc, td, and during the reception step 614. the data receiver 114 receives the time-stamped data which has a date after the first reference time ta, tb, tc and earlier than the second reference time tb, tc, td.

Comme cela a été explicité ci-dessus, la détermination du premier instant de référence ta, tb, tc et éventuellement du deuxième instant de référence tb, tc, td s'effectue à partir de la base de données du récepteur de données 114, dans laquelle sont enregistrées des données horodatées qui ont été reçues du chronotachygraphe 112 antérieurement à l'exécution de ce procédé de réception. Les instants de référence sont déterminés en fonction des transferts de données qui ont été effectués antérieurement et qui ont été correctement réalisés.As explained above, the determination of the first reference time ta, tb, tc and possibly the second reference time tb, tc, td is carried out from the database of the data receiver 114, in which are recorded time stamped data received from the tachograph 112 prior to the execution of this reception method. The instants of reference are determined according to the data transfers which were carried out previously and which were correctly carried out.

La sélection du premier instant de référence et, éventuellement, du deuxième instant de référence permet de garantir la continuité des données horodatées qui sont reçues par le récepteur de données 114. Si le transfert antérieur est plus vieux que 90 jours, le système de l'état de la technique ne permet pas de récupérer les données horodatées antérieures et donc ne permet pas de garantir la continuité des données horodatées reçues.The selection of the first reference time and possibly the second reference time makes it possible to guarantee the continuity of the time stamped data received by the data receiver 114. If the previous transfer is older than 90 days, the system of the state of the art does not recover the previous date stamped data and therefore does not guarantee the continuity of the received time stamped data.

Pour éviter que le récepteur de données 114 reçoivent des données d'un chronotachygraphe 112 qui n'est pas autorisé à émettre vers ce récepteur de données 114, et pour classer les données horodatées reçues par le récepteur de données 114 en fonction du chronotachygraphe 112 émetteur, le premier module de communication 118 émet un identifiant du chronotachygraphe 112 qui est analysé par le récepteur de données 114 qui, en fonction du résultat de l'analyse de l'identifiant, autorise ou non le transfert de données horodatées. Cet identifiant peut consister en l'immatriculation du véhicule, un numéro identifiant le chronotachygraphe, l'identité de l'entreprise, et autres.To prevent the data receiver 114 from receiving data from a tachograph 112 which is not authorized to transmit to this data receiver 114, and to classify the time stamped data received by the data receiver 114 as a function of the tachograph 112 tachograph , the first communication module 118 transmits an identifier of the tachograph 112 which is analyzed by the data receiver 114 which, depending on the result of the analysis of the identifier, allows or not the transfer of time stamped data. This identifier may consist of the registration of the vehicle, a number identifying the tachograph, the identity of the company, and others.

Le procédé de transfert comprend alors, entre l'étape d'établissement 502 et l'étape de réception 512, une étape d'émission d'un identifiant 508, une étape de réception du résultat du test d'identification de l'identifiant 510, et l'étape de réception 512, l'étape de récupération 518 et l'étape de transfert 514 sont exécutées si le résultat du test d'identification de l'identifiant est positif.The transfer method then comprises, between the establishment step 502 and the reception step 512, a step of issuing an identifier 508, a step of receiving the result of the identification identification test 510. , and the receiving step 512, the recovery step 518 and the transfer step 514 are executed if the result of the identifier identification test is positive.

Le procédé de réception comprend alors entre l'étape de réception de la demande d'établissement 602 et l'étape d'émission 612, une étape de réception de l'identifiant 608, une étape de test d'identification de l'identifiant 610, une étape d'émission du résultat du test d'identification de l'identifiant 610, et l'étape d'émission 612 et l'étape de réception 614 sont exécutées si le résultat du test d'identification de l'identifiant est positif.The reception method then comprises between the step of receiving the establishment request 602 and the sending step 612, a step of receiving the identifier 608, an identifying identification test step 610. , a step of transmitting the result of the identification test of the identifier 610, and the sending step 612 and the receiving step 614 are executed if the result of the identification identification test is positive. .

Les données horodatées représentent les données du véhicule 108 et elles sont enregistrées dans la mémoire vive 204, mais il peut être souhaitable de transférer également les données relatives au conducteur. Ces données relatives au conducteur sont enregistrées dans une carte à puce qui vient se loger dans le lecteur de carte du deuxième type 124. Par exemple, lorsque le conducteur change de véhicule, il prend sa carte et l'introduit dans le lecteur de carte du deuxième type 124 du nouveau véhicule. L'ensemble des données relatives au conducteur permet, en particulier, de vérifier son emploi du temps et d'établir des statistiques de gestion afin, par exemple, d'établir sa feuille de paie. Pour récupérer les données relatives au conducteur, le récepteur de données 114 doit informer le premier boîtier de communication 118 connecté au chronotachygraphe 112 qui doit à son tour récupérer les données correspondantes sur la carte à puce par l'intermédiaire du lecteur de carte du deuxième type 124 du chronotachygraphe 112 afin de les transmettre avec les données horodatées.The time stamped data represents the data of the vehicle 108 and is stored in the RAM 204, but it may be desirable to also transfer the data relating to the driver. These data relating to the driver are recorded in a smart card which is housed in the card reader of the second type 124. For example, when the driver changes vehicle, he takes his card and introduces it into the card reader of the card. second type 124 of the new vehicle. In particular, all the data relating to the driver makes it possible to check his schedule and to establish management statistics in order, for example, to establish his payroll. To recover the data relating to the driver, the data receiver 114 must inform the first communication box 118 connected to the tachograph 112 which in turn must recover the corresponding data on the smart card via the card reader of the second type. 124 of the tachograph 112 to transmit them with the time stamped data.

Ainsi au cours de l'étape d'émission 612, le récepteur de données 114 émet une requête d'émission de données relatives au conducteur et au cours de l'étape de réception 614, les données relatives au conducteur sont reçues du chronotachygraphe 112.Thus during the transmission step 612, the data receiver 114 sends a request for transmission of data relating to the driver and during the reception step 614, the data relating to the driver are received from the tachograph 112.

De la même manière, au cours de l'étape de réception 512, le premier module de communication 118 reçoit une requête d'obtention de données relatives au conducteur au cours de l'étape de récupération 518, les données relatives au conducteur sont récupérées, à travers le chronotachygraphe 112, par le premier module de communication 118, et au cours de l'étape de transfert 514, les données relatives au conducteur sont transférées vers le récepteur de données 114.In the same way, during the reception step 512, the first communication module 118 receives a request for obtaining data relating to the driver during the recovery step 518, the data relating to the driver is retrieved, through the tachograph 112, by the first communication module 118, and during the transfer step 514, the data relating to the driver is transferred to the data receiver 114.

Dans un mode de réalisation particulier de l'invention, l'étape d'établissement 502 du procédé de transfert est déclenchée par l'introduction d'une carte d'identification dans l'un des lecteurs de carte 122, 124 du chronotachygraphe 112. L'introduction de la carte d'identification fait passer le chronotachygraphe 112 du mode attente au mode émission et lorsque le premier module de communication 118 scrute l'état du chronotachygraphe 112, il détecte ce mode et commence le procédé de transfert, c'est-à-dire l'étape d'établissement 502. Cette carte peut être, par exemple, la carte de l'entreprise, la carte atelier, la carte contrôleur ou autres. Ainsi, lorsque le conducteur souhaite transmettre les données horodatées ou vérifier si le récepteur de données 114 est en attente de ces données, il introduit la carte d'identification dans le lecteur de carte du premier type 122, ce qui initie le procédé de transfert du premier module de communication 118 et le procédé de réception du récepteur de données 114 en réponse à l'étape d'établissement de la communication radio 502.In a particular embodiment of the invention, the establishment step 502 of the transfer process is triggered by the introduction of a card identification card in one of the card readers 122, 124 of the tachograph 112. The introduction of the identification card switches the tachograph 112 from standby mode to the transmission mode and when the first communication module 118 scans the state of the tachograph 112, it detects this mode and begins the transfer process, that is to say the establishment step 502. This card can be, for example, the company card, the workshop card, the controller board or others. Thus, when the driver wishes to transmit the time-stamped data or to check whether the data receiver 114 is waiting for this data, he introduces the identification card into the card reader of the first type 122, which initiates the method of transferring the data. first communication module 118 and the receiving method of the data receiver 114 in response to the setting step of the radio communication 502.

Après l'étape de réception 602 de demande d'établissement de la communication radio, le processus peut se poursuivre par une étape d'acquittement 606 au cours de laquelle le récepteur de données 114 émet un signal d'acquittement représentatif du fait qu'il accepte ou qu'il n'accepte pas d'établir la communication radio.After the radio call setup request receiving step 602, the process may proceed with an acknowledgment step 606 in which the data receiver 114 transmits an acknowledgment signal representative of the fact that it accepts or does not agree to establish radio communication.

Parallèlement, après l'étape d'établissement de la communication radio 502, le processus se poursuit par une étape d'attente 506 au cours de laquelle le boîtier de communication 118 relié au chronotachygraphe 112 reçoit le signal d'acquittement et, selon la signification du signal d'acquittement, le processus de transfert se poursuit ou s'arrête.At the same time, after the step of setting up the radio communication 502, the process continues with a waiting step 506 during which the communication box 118 connected to the tachograph 112 receives the acknowledgment signal and, according to the meaning of the acknowledgment signal, the transfer process continues or stops.

Lorsque le récepteur de données 114 refuse d'établir la communication (étape 606) ou ne reconnaît pas l'identifiant (étape 610), le processus de réception se poursuit par l'étape d'arrêt de la communication 616.When the data receiver 114 refuses to establish communication (step 606) or does not recognize the identifier (step 610), the reception process continues with the step of stopping communication 616.

De la même manière, lorsque le boîtier de communication 118 reçoit le refus d'établissement de la communication radio (étape 506) ou le rejet de l'identifiant (étape 510), le processus de transfert se poursuit par l'étape d'arrêt de la communication 516.In the same way, when the communication box 118 receives the refusal of establishment of the radio communication (step 506) or the rejection of the identifier (step 510), the transfer process continues with the stopping step of the communication 516.

Pour éviter tout transfert de données, lorsque la base de données du récepteur de données 114 est à jour, le récepteur de données 114 émet, lorsque l'identifiant du chronotachygraphe 112 a été reconnu, un indicateur de refus de transfert. Cet indicateur peut, par exemple, être émis lors de l'étape d'émission du résultat du test d'identification de l'identifiant 610. Après cette émission, le processus de réception passe à l'étape d'arrêt de la communication 616 pour le récepteur de données 114 et le processus de transfert passe à l'étape d'arrêt de la communication 516 pour le boîtier de communication 118 connecté au chronotachygraphe 112.To avoid any data transfer, when the database of the data receiver 114 is up to date, the data receiver 114 transmits, when the identifier of the tachograph 112 has been recognized, a transfer refusal indicator. This indicator can, for example, be emitted during the step of transmitting the result of the identification test of the identifier 610. After this transmission, the reception process goes to the step of stopping the communication 616 for the data receiver 114 and the transfer process goes to the stop of the communication step 516 for the communication box 118 connected to the tachograph 112.

Pour améliorer la sécurité des données et éviter toute manipulation, les données sont rendues infalsifiables par apposition d'une signature électronique. La signature électronique est apposée sur les données lors de l'introduction de la carte entreprise qui contient les codes nécessaires à la réalisation de la signature électronique.To improve the security of the data and to avoid any manipulation, the data are rendered unfalsifiable by affixing an electronic signature. The electronic signature is affixed to the data during the introduction of the company card which contains the codes necessary for the realization of the electronic signature.

Bien entendu, la présente invention n'est pas limitée aux exemples et modes de réalisation décrits et représentés, mais elle est susceptible de nombreuses variantes accessibles à l'homme de l'art.Of course, the present invention is not limited to the examples and embodiments described and shown, but it is capable of many variants accessible to those skilled in the art.

Par exemple, l'invention a été plus particulièrement décrite dans le cas d'un premier module de communication séparé du chronotachygraphe, mais il peut être intégré au chronotachygraphe qui comprend alors le premier module de communication.For example, the invention has been more particularly described in the case of a first separate communication module of the tachograph, but it can be integrated in the tachograph which then comprises the first communication module.
