Description
Dispositif de communication Communication device
La présente invention concerne un dispositif de communication radio comprenant un premier module communication radio et un boîtier de commande comprenant un deuxième module de communication, lesquels premier et deuxième modules de communication sont agencés pour communiquer par radio fréquence à courte distance de portée de radio entre eux. The present invention relates to a radio communication device comprising a first radio communication module and a control box comprising a second communication module, which first and second communication modules are arranged to communicate by radio frequency at short radio range distance between them .
Les utilisateurs de terminaux radios, tels que par exemple des policiers ou des pompiers, utilisent actuellement différents types de radios sur les réseaux radios digitaux. Il existe diverses technologies de réseaux digitaux parmi lesquelles on peut citer Tetra, Tetrapol, DMR, ... Users of radio terminals, such as, for example, police officers or firefighters, currently use different types of radios on digital radio networks. There are various technologies of digital networks among which we can mention Tetra, Tetrapol, DMR, ...
Les utilisateurs dit «nomades» utilisent des radios portables qu'ils transportent avec eux lors de leurs déplacements. Ces radios portables sont éventuellement connectées à des accessoires audio permettant de parler ou d'écouter une conversation via par exemple une oreillette. Users called "nomads" use portable radios that they carry with them while traveling. These portable radios are optionally connected to audio accessories for speaking or listening to a conversation via for example a headset.
Les véhicules d'intervention sont la plupart du temps équipés de radios qui restent fixes dans le véhicule. C'est majoritairement le cas pour les motos, mais aussi les voitures et les autres véhicules d'intervention, type voitures de police, de pompiers ou ambulances par exemple. Intervention vehicles are mostly equipped with radios that remain fixed in the vehicle. This is mainly the case for motorcycles, but also cars and other intervention vehicles, such as police cars, firefighters or ambulances for example.
A ce jour, la plupart des motos utilisées par les services de sécurité sont équipées d'une radio fixée sur le véhicule. Un câble est également connecté entre ia moto et le casque du conducteur, afin de permettre au conducteur de pouvoir utiliser sa radio lorsqu'il conduit. To date, most motorcycles used by the security services are equipped with a radio attached to the vehicle. A cable is also connected between the motorcycle and the driver's helmet, to allow the driver to use his radio while driving.
Pour les radios fixées au guidon d'une moto d'un service d'intervention habituellement quatre autres fonctionnalités sont prévues sur cette radio sur les parties droite et gauche du guidon : For radios attached to the handlebars of a motorcycle service intervention usually four other features are provided on this radio on the left and right parts of the handlebar:
• la première est principalement utilisée pour changer de groupe au niveau des canaux de communication radio mais également pour contrôler le volume;
• la deuxième permet de passer un appel via le bouton «push-to-talk»; • the former is mainly used to change the group at the level of the radio communication channels but also to control the volume; • the second makes it possible to make a call via the push-to-talk button;
• la troisième permet de lancer un appel d'urgence; • the third allows you to initiate an emergency call;
• la quatrième est le panneau de commande de la radio, utilisé principalement pour avoir une indication visuelle sur l'état de la communication, sur le groupe de communication sélectionné, sur l'identité de l'appelant, etc.... • the fourth is the control panel of the radio, used mainly to have a visual indication of the state of the communication, the selected communication group, the identity of the caller, etc.
A ce jour, les membres des services de sécurité utilisent dès lors la radio fixée au véhicule lorsqu'ils utilisent leurs motos et éventuellement une radio portable lorsqu'ils quittent la moto. L'usage de deux radios lors de certaines interventions est compliqué et moins efficace. En effet, les utilisateurs doivent utiliser la radio portable lorsqu'ils ne conduisent pas leurs véhicules et la radio fixe lorsqu'ils circulent avec la moto. To date, members of the security services are using the radio attached to the vehicle when they use their motorcycles and possibly a portable radio when they leave the bike. The use of two radios during some interventions is complicated and less effective. In fact, users must use the portable radio when they do not drive their vehicles and the stationary radio when they travel with the motorcycle.
En ce qui concerne les voitures par contre, elles sont soit équipées de la radio installée à demeure dans le véhicule, soit d'une radio portable fixée dans un car kit. En effet, dans une voiture ou un camion, un chauffeur est rarement seul laissant dès lors la possibilité au passager de se charger de la radio. Regarding the cars however, they are either equipped with the radio installed permanently in the vehicle, or a portable radio fixed in a car kit. Indeed, in a car or a truck, a driver is rarely alone leaving the passenger the opportunity to take charge of the radio.
Puisque les radios sont généralement utilisées par des services de sécurité (police, pompiers, ambulance, armée, ...), les utilisateurs souhaitant préserver le caractère confidentiel de leurs communications, une liaison sans fil entre la radio et un accessoire extérieur utilisant des technologies commerciales non-sécurisées n'est pas autorisée. Idéalement, ces utilisateurs requièrent l'utilisation d'un système de communication encrypté afin de s'assurer de la confidentialité des communications. Since radios are generally used by security services (police, fire brigade, ambulance, army, ...), users wishing to preserve the confidentiality of their communications, a wireless link between the radio and an external accessory using technologies unsecured business is not allowed. Ideally, these users require the use of an encrypted communication system to ensure the confidentiality of communications.
L'invention a pour but de réaliser un dispositif de communication permettant à son utilisateur de garder la majorité des fonctionnalités décrites ci-dessus, à savoir l'utilisation de la radio en
conduisant et fonctionnalités habituelles au guidon, mais via l'utilisation d'un radio portable et non plus d'une radio installée à demeure dans ou sur le véhicule. The object of the invention is to provide a communication device enabling its user to retain the majority of the functionalities described above, namely the use of radio in driving and usual features on the handlebars, but through the use of a portable radio and no longer a permanently installed radio in or on the vehicle.
A cette fin, un dispositif suivant l'invention est caractérisé en ce que le premier module de communication radio comporte une interface de communication périphérique agencée pour y brancher une radio portable agencée pour recevoir et émettre des messages et être placée sur un véhicule, lequel boîtier de commande est équipé de moyens de commande reliés au deuxième module de communication et agencés pour commander la radio portable, lesquels premier et deuxième module de communication sont pourvus de moyens d'appairage agencés pour appairer le premier et le deuxième module de communication entre eux lorsqu'ils se trouvent à portée de radio entre eux et d'allouer, après appareillage, un canal de communication unique entre le premier et le deuxième module de communication, lesquels moyens d'appairage sont également agencés pour surveiller si le premier et le deuxième module de communication restent à une distance d'émission-réception prédéterminée entre eux et pour rompre la communication lorsque cette distance prédéterminée a été dépassée et la rétablir lorsque le premier et le deuxième module de communication se trouvent à nouveau endéans cette distance prédéterminée. L'avantage du dispositif de communication suivant l'invention est qu'il permet à son utilisateur d'utiliser une seule et unique radio lorsqu'il est à bord de son véhicule ou à pied. Ceci permet à l'utilisateur, lors d'une intervention des services de secours, de quitter rapidement son véhicule sans se soucier de brancher une autre radio. En effet, le boîtier de commande peut être installé sur le véhicule alors que la radio reste portable. En réalisant l'appairage entre les deux modules de communication, le premier module et le boîtier de commande sont en communication entre eux. De plus, comme cette communication est réalisée sur un canal de communication unique entre les deux modules, la confidentialité de la communication est assurée. Enfin
puisque la communication est rompue si la distance prédéterminée entre les deux modules est dépassée, la portée sur laquelle la communication est diffusée reste limitée, ce qui contribue également à la confidentialité de la communication. To this end, a device according to the invention is characterized in that the first radio communication module comprises a peripheral communication interface arranged to connect a portable radio arranged to receive and transmit messages and be placed on a vehicle, which housing control device is equipped with control means connected to the second communication module and arranged to control the portable radio, which first and second communication module are provided with pairing means arranged to pair the first and the second communication module between them when they are in radio range between them and allocate, after switchgear, a single communication channel between the first and the second communication module, which pairing means are also arranged to monitor whether the first and the second module of communication remain at a predetermined transmission-reception distance between them and to break the communication when this predetermined distance has been exceeded and restore it when the first and the second communication module are again within this predetermined distance. The advantage of the communication device according to the invention is that it allows the user to use a single radio while on board his vehicle or on foot. This allows the user, during an intervention of the emergency services, to quickly leave his vehicle without worrying about connecting another radio. Indeed, the control box can be installed on the vehicle while the radio remains portable. By performing the pairing between the two communication modules, the first module and the control box are in communication with each other. Moreover, as this communication is performed on a single communication channel between the two modules, the confidentiality of the communication is ensured. Finally since the communication is broken if the predetermined distance between the two modules is exceeded, the range over which the communication is broadcast remains limited, which also contributes to the confidentiality of the communication.
Une première forme de réalisation préférentielle d'un dispositif suivant l'invention est caractérisée en ce que le boîtier de commande comporte un identificateur et en ce que les moyens d'appairage sont agencés pour diffuser cycliquement l'identificateur. Ceci permet d'identifier le boîtier de commande de façon unique et d'ainsi limiter l'appairage à ce seul boîtier de commande. A first preferred embodiment of a device according to the invention is characterized in that the control unit comprises an identifier and in that the pairing means are arranged to cyclically diffuse the identifier. This makes it possible to identify the control box uniquely and thus limit the pairing to this single control box.
Une deuxième forme de réalisation préférentielle d'un dispositif suivant l'invention est caractérisée en ce que le boîtier de commande comporte un afficheur agencé pour afficher des fonctions de commande de la radio portable. Ceci permet à l'utilisateur de voir les fonctions à choisir et choisies. A second preferred embodiment of a device according to the invention is characterized in that the control unit comprises a display arranged to display control functions of the portable radio. This allows the user to see which functions to choose and select.
Une troisième forme de réalisation préférentielle d'un dispositif suivant l'invention est caractérisée en ce que les moyens d'appairage sont agencés pour fixer la portée de radio à un maximum de deux mètres lors de l'appairage. Ceci permet amplement de couvrir la distance entre le premier et le deuxième module lorsqu'ils sont en phase d'initialisation et donc de limiter la portée de la diffusion durant cette phase. A third preferred embodiment of a device according to the invention is characterized in that the pairing means are arranged to set the radio range to a maximum of two meters during pairing. This makes it possible to cover the distance between the first and second modules while they are in the initialization phase and thus to limit the scope of the broadcast during this phase.
L'invention sera maintenant décrite plus en détails à l'aide des dessins qui illustrent une forme de réalisation préférentielle du dispositif suivant l'invention. Dans les dessins : The invention will now be described in more detail with the aid of the drawings which illustrate a preferred embodiment of the device according to the invention. In the drawings:

Dans les dessins un même signe de référence a été attribué à un même élément ou à un élément analogue. Figure 4 illustrates the operation of the device using a flowchart. In the drawings, the same reference sign has been assigned to the same element or to a similar element.
Pour des raisons de clarté la description de l'invention sera limitée à l'exemple d'un usage pour une moto, mais il va de soi que le dispositif de communication suivant l'invention n'est pas limité à un usage sur des motos et qu'il peut s'appliquer à tout type de véhicule. For the sake of clarity, the description of the invention will be limited to the example of a use for a motorcycle, but it goes without saying that the communication device according to the invention is not limited to use on motorcycles and that it can apply to any type of vehicle.
Le dispositif de communication illustré à ia figure 1 comporte un premier module de communication radio 1 et un boîtier de commande 2 qui sont agencés pour communiquer entre eux par radio fréquence à courte distance de portée de radio. Par courte distance on entend une distance inférieure à 50 m, en particulier entre 10 et 20 m. Le premier module de communication 1 comporte une interface de communication périphérique 3 qui est agencée pour y brancher un terminal radio portable 4. L'interface de communication périphérique 3 est de préférence du type PEI (Peripheral Equipment Interface). Le boîtier de commande 2 comporte un deuxième module de communication 6 pour communiquer sans fil avec le premier module de communication. Le boîtier de commande 2 dispose de préférence d'un afficheur 5 et de boutons poussoir. Le boîtier de commande comporte de préférence un identificateur qui l'identifie de façon unique. The communication device illustrated in FIG. 1 comprises a first radio communication module 1 and a control box 2 which are arranged to communicate with one another by radio frequency at a short radio range distance. Short distance means a distance of less than 50 m, in particular between 10 and 20 m. The first communication module 1 comprises a peripheral communication interface 3 which is arranged to connect a portable radio terminal 4. The peripheral communication interface 3 is preferably of the type PEI (Peripheral Equipment Interface). The control unit 2 comprises a second communication module 6 for communicating wirelessly with the first communication module. The control box 2 preferably has a display 5 and push buttons. The control box preferably has an identifier that uniquely identifies it.
Le dispositif de communication permet l'établissement d'une liaison radiofréquence (liaison RF) bidirectionnelle offrant la possibilité de disposer d'une interface de commande sur un périphérique distant. Dans l'exemple illustré il s'agit du boîtier de commande 2 fixé sur une moto et qui permet de contrôler un terminal radio portable 4 au travers du premier module de communication RF 1 connecté physiquement sur son port accessoire et doté du port de communication série 3 dit PEI. L'afficheur 5 permet à l'utilisateur une consultation visuelle, rapide et en toute sécurité des informations d'exploitation du terminal radio portable. Un périphérique d'entrée disposant de boutons poussoir est connecté sur ou fait partie du boîtier de commande afin d'effectuer des actions sur le termina! radio
portable qui sont transmises sur la liaison RF établie entre le boîtier de commande et le premier module de communication RF. The communication device allows the establishment of a bidirectional radio frequency link (RF link) offering the possibility of having a control interface on a remote device. In the illustrated example, it is the control box 2 fixed on a motorcycle and which makes it possible to control a portable radio terminal 4 through the first RF communication module 1 physically connected to its accessory port and equipped with the serial communication port. 3 says PEI. The display 5 allows the user a visual, fast and safe consultation of the operating information of the portable radio terminal. An input device with pushbuttons is connected to or part of the control box to perform actions on the termina! radio portable that are transmitted over the RF link established between the control box and the first RF communication module.
Pour la communication entre le premier et le deuxième module de communication il est de préférence fait usage d'une liaison RF multicanaux à courte distance du type 868MHz, Bluetooth ou autre. Les communications RF entre le boîtier de commande et le premier module de communication RF peuvent être cryptées au moyen d'un algorithme tel que par exemple l'algorithme AES 256 bits. For communication between the first and the second communication module, it is preferably used a short-range multichannel RF link of the type 868 MHz, Bluetooth or other. The RF communications between the control box and the first RF communication module can be encrypted by means of an algorithm such as for example the 256-bit AES algorithm.
L'établissement de la liaison entre le premier et le deuxième module de communication ne peut être réalisé que lorsque ceux-ci ont été préalablement appairés. A cette fin le premier et le deuxième module de communication sont pourvus de moyens d'appairage agencés pour appairer le premier et le deuxième module de communication entre eux lorsqu'ils se trouvent à portée de radio entre eux. Cette fonction d'appairage est réalisée à l'initiative d'un opérateur qui doit déclencher une procédure spécifique lorsque les deux modules sont à portée radio, c'est-à-dire de préférence pas plus de 2 mètres l'une de l'autre. Les deux modules de communication se positionnent alors sur un canal de communication dédié pour tenter un appairage au cours duquel le boîtier de commande diffuse cycliquement son identificateur unique, par exemple un mot binaire de quatre digits, dans l'attente d'un acquittement en provenance du premier module de communication RF. Une fois i'appairage effectué, les deux modules de communication sont prêts pour communiquer sur un canal de communication unique avec une entête de trame RF unique. Tant le canal de communication unique que l'entête sont déterminés en fonction de l'identificateur du boîtier de commande. The connection between the first and the second communication module can only be established when these have been previously paired. For this purpose the first and the second communication module are provided with pairing means arranged to pair the first and the second communication module between them when they are in radio range with each other. This pairing function is performed at the initiative of an operator who must trigger a specific procedure when the two modules are in radio range, that is to say preferably no more than 2 meters one of the other. The two communication modules then position themselves on a dedicated communication channel to attempt a pairing during which the control unit cyclically broadcasts its unique identifier, for example a four-digit binary word, pending an acknowledgment from of the first RF communication module. Once paired, the two communication modules are ready to communicate on a single communication channel with a single RF frame header. Both the unique communication channel and the header are determined according to the identifier of the control box.
La portée des communications est réduite volontairement afin d'éviter les interférences si plusieurs dispositifs doivent cohabiter dans un périmètre réduit. De plus, le dispositif n'a d'intérêt que lorsque l'utilisateur qui porte le terminal radio portable se trouve à proximité du boîtier de
commande pour effectuer des actions sur ies boutons poussoir de ce dernier. Néanmoins, en cas de nécessité la portée peut atteindre 10 à 20 mètres voir plus. Les commandes au clavier du terminal radio portable restent actives à tout moment. The range of communications is voluntarily reduced to avoid interference if several devices must coexist in a small area. Moreover, the device is of interest only when the user who carries the portable radio terminal is close to the housing of command to perform actions on the push buttons of the latter. Nevertheless, in case of necessity the range can reach 10 to 20 meters or more. The keypad commands of the portable radio terminal remain active at all times.
Les moyens d'appairage sont également agencés pour surveiller si le premier et ie deuxième module de communication restent à une distance d'émission-réception prédéterminée, de par exemple 20 mètres, entre eux et pour rompre la communication lorsque cette distance prédéterminée a été dépassée et la rétablir lorsque le premier et le deuxième module de communication se trouvent à nouveau endéans cette distance prédéterminée. Ainsi, lorsque le motard s'éloigne de sa moto au- delà de la distance prédéterminée au point d'être hors de portée du boîtier de commande et que ce dernier ne reçoit plus de réponses aux interrogations cycliques, la connexion est alors rompue et un message de perte de connexion est présenté sur l'afficheur du boîtier de commande qui devient inopérant même si l'on appuie sur ses boutons poussoir. Dès lors, le terminal radio portable 4 peut être contrôlé uniquement depuis son clavier et son écran. Lorsque le motard revient vers sa moto, le premier module de communication RF répond de nouveau aux interrogations cycliques en provenance du boîtier de commande et ia communication est rétablie automatiquement. Les commandes sont à nouveau disponibles depuis le boîtier de commande. The pairing means are also arranged to monitor whether the first and the second communication module remain at a predetermined transmission-reception distance, for example 20 meters, between them and to break the communication when this predetermined distance has been exceeded. and restore it when the first and the second communication module are again within this predetermined distance. Thus, when the rider moves away from his motorcycle beyond the predetermined distance to the point of being out of reach of the control box and the latter no longer receives responses to cyclic interrogations, the connection is then broken and a Loss of connection message is presented on the display of the control box that becomes inoperative even if you press the buttons. Therefore, the portable radio terminal 4 can be controlled only from its keyboard and its screen. When the rider returns to his motorcycle, the first RF communication module again responds to the cyclic interrogations from the control box and the communication is automatically restored. The controls are available again from the control box.
Comme indiqué ci-dessus, le premier module de communication RF est connecté à l'interface de communication périphérique de la radio portable. Le premier module de communication RF permet également la connexion à un accessoire audio (par exemple micro-haut parleur déporté) qui lui-même pourra être relié à un accessoire audio intégré dans le casque. As indicated above, the first RF communication module is connected to the peripheral communication interface of the portable radio. The first RF communication module also allows the connection to an audio accessory (for example remote micro-speaker) which itself can be connected to an audio accessory integrated in the headset.
La figure 2 illustre une forme de réalisation du premier module de communication 1. Le premier module de communication RF est
physiquement connecté au terminal radio portable 4 sur le port 3 accessoire qui délivre une alimentation électrique 9 et propose une interface de communication série dite PEI. Le premier module de communication RF comporte un microcontrôleur 7 ainsi qu'un module à radio fréquence 8 qui permettent de déporter les commandes du terminal radio portable jusqu'au boîtier de commande sans aucune liaison filaire, celle-ci étant assurée par liaison RF. Le premier module de communication RF joue donc un rôle de passerelle de communication entre le port PEI 3 du terminal radio portable et le boîtier de commande distant. FIG. 2 illustrates an embodiment of the first communication module 1. The first RF communication module is physically connected to the portable radio terminal 4 on the accessory port 3 which delivers a power supply 9 and proposes a serial communication interface called PEI. The first RF communication module comprises a microcontroller 7 and a radio frequency module 8 which allow to deport the controls of the portable radio terminal to the control box without any wired connection, the latter being provided by RF link. The first RF communication module therefore acts as a communication gateway between the PEI port 3 of the portable radio terminal and the remote control unit.
Le boîtier de commande 2 illustré à la figure 3 est bien entendu alimenté via l'alimentation 10 existante de la moto, mais une alimentation individuelle, par exemple par batterie, peut également être envisagée. Le boîtier de commande comporte le deuxième module de communication 6 ainsi qu'un microcontrôieur 11. A ce dernier plusieurs boutons poussoir 12, 13 et 14 sont connectés. Ces boutons poussoir peuvent être des boutons mécaniques où des boutons tactiles placés de manière accessible pour un confort d'utilisation maximum. Il est possible d'affecter une ou plusieurs fonctions à chacun de ces boutons poussoir, changement de groupe de communication et modification de volume 14, bouton PTT (Push To Talk), appel d'urgence 13 par exemple. Le microcontrôieur 11 ainsi que le deuxième module de communication RF 6 permettent de déporter les commandes du boîtier de commande jusqu'au premier module de communication 1 et ainsi au terminal radio portable 4 sans aucune liaison filaire, celle-ci étant assurée par liaison RF. Le premier module de communication RF joue donc un rôie de passerelle de communication entre le périphérique d'entrée du boîtier de commande et le terminal radio portable distant. De plus, le boîtier de commande dispose de préférence d'un afficheur rétro éclairé permettant une utilisation de jour comme de nuit. The control unit 2 illustrated in FIG. 3 is of course supplied via the existing power supply 10 of the motorcycle, but an individual power supply, for example by battery, can also be envisaged. The control unit comprises the second communication module 6 and a microcontroller 11. At the latter several push buttons 12, 13 and 14 are connected. These pushbuttons can be mechanical buttons or touch buttons placed in an accessible way for maximum comfort of use. It is possible to assign one or more functions to each of these push buttons, change of communication group and volume modification 14, push to talk (PTT) button, emergency call 13 for example. The microcontroller 11 as well as the second RF communication module 6 make it possible to transfer the controls from the control box to the first communication module 1 and thus to the portable radio terminal 4 without any wired connection, this being provided by an RF link. The first RF communication module therefore plays a communication gateway role between the input device of the control box and the remote portable radio terminal. In addition, the control box preferably has a backlit display for use day or night.
Le dispositif de communication suivant l'invention utilise par exemple des terminaux radio numériques Tetra de la marque Cassidian.
Bien entendu d'autres terminaux ayant ces fonctionnalités peuvent être utilisés. Le dispositif de communication est par exemple réalisé sur base de terminaux radios utilisant la technologie Tetra. Cette même solution pourra être développée tant pour les véhicules disposant d'une source d'alimentation que pour les autres véhicules avec d'autres technologies radios numériques comme par exemple les technologies Tetrapol, D R ou DPMR. The communication device according to the invention uses, for example, Tetra digital radio terminals of the Cassidian brand. Of course other terminals having these features can be used. The communication device is for example made on the basis of radio terminals using Tetra technology. This solution can be developed both for vehicles with a power source and for other vehicles with other digital radio technologies such as Tetrapol, DR or DPMR technologies.
La communication entre les modules est réalisée au moyen d'échanges de messages entre le boîtier de commande et le premier module de communication RF relié à la radio. La figure 4 illustre cette communication. Le boîtier de commande, après appairage, envoie 20 des trames d'interrogation cycliques auxquelles le premier module de communication répond 21. Suite à cela le boîtier de commande affiche 22 les informations reçues sur son moyen d'affiche. Si une commande a été activée 23 sur le boîtier de commande, cette dernière est transmise au premier module de communication qui la reçoit 24. Le premier module de communication répond 25 à cette commande et au boîtier de commande qui va mettre à jour 26 l'affichage des données. Les commandes sont alors transmises 27 au premier module qui les transmet 28 à la radio pour exécution. The communication between the modules is achieved by means of message exchanges between the control box and the first RF communication module connected to the radio. Figure 4 illustrates this communication. The control unit, after pairing, sends cyclic interrogation frames to which the first communication module responds. Following this, the control unit displays the information received on its display means. If a command has been activated 23 on the control box, the latter is transmitted to the first communication module which receives it 24. The first communication module responds to this command and to the control unit which will update 26 the display of data. The commands are then transmitted to the first module which transmits them to the radio for execution.
Par exemple, lorsque l'utilisateur appuie sur le bouton PTT, le microcontrôleur du boîtier de commande détecte cette action et envoie un message dans une trame RF à destination du premier module de communication RF. Ce dernier reçoit le message puis le décode afin de déterminer l'action à exécuter sur le terminal radio portable. Si le message correspond à une action valide, le microcontrôieur du premier module de communication RF envoie une commande sur le port PE1 du terminal radio portable pour solliciter son passage en émission sur le réseau de radiocommunication (TETRA, DMR, etc.). Les messages entre les deux modules peuvent être acquittés et réitérés en cas d'échec.
Dans le cas d'échange de messages par des forces d'intervention, Il est très important que ce protocole soit sécurisé et fiable, afin qu'il ne soit pas perturbé ou qu'il ne perturbe pas une autre communication véhicule - boîtier, car il est en effet très fréquent que deux ou plusieurs motos roulent dans le même environnement lors de déplacements de routine ou pour des escortes. For example, when the user presses the PTT button, the microcontroller of the control box detects this action and sends a message in an RF frame to the first RF communication module. The latter receives the message and then decodes it in order to determine the action to be performed on the portable radio terminal. If the message corresponds to a valid action, the microcontroller of the first RF communication module sends a command on the port PE1 of the portable radio terminal to request its transmission on the radio network (TETRA, DMR, etc.). The messages between the two modules can be acknowledged and reiterated in case of failure. In the case of message exchange by intervention forces, it is very important that this protocol is secure and reliable, so that it is not disturbed or disturbs another vehicle-to-case communication because it is indeed very common that two or more motorcycles ride in the same environment during routine trips or for escorts.
Afin d'éviter des conflits ou perturbations entre plusieurs boîtiers de commande, une entête de trame RF unique par boîtier de commande est intégrée au protocole de transfert radio. In order to avoid conflicts or disturbances between several control boxes, a single RF frame header per control box is integrated in the radio transfer protocol.
Le protocole de communication inclura donc systématiquement l'adresse de l'émetteur du message et un caractère de contrôle (CRC (Cyclic Redundance Check) ou autre) permettant de vérifier l'intégrité de la transmission. Lorsque des messages sont échangés entre le boîtier de commande et le premier module de communication RF, une entête de trame RF unique déterminée en fonction de l'identité du boîtier de communication lors de l'étape d'appairage permet d'éviter tout conflit lorsque plusieurs systèmes fonctionnent simultanément dans un périmètre réduit. Un seul boîtier de commande peut communiquer avec un seul module de communication RF. En cas de problème de transmission les messages peuvent être répétés. El est également possible d'attribuer une fréquence différente à chaque boîtier moto, en fonction de son adresse, ceci afin de limiter la répétition de messages.
The communication protocol will therefore systematically include the address of the sender of the message and a control character (CRC (Cyclic Redundancy Check) or other) to verify the integrity of the transmission. When messages are exchanged between the control box and the first RF communication module, a unique RF frame header determined according to the identity of the communication box during the pairing step avoids any conflict when several systems operate simultaneously in a small area. A single control box can communicate with a single RF communication module. In case of transmission problem the messages can be repeated. It is also possible to assign a different frequency to each motorcycle box, depending on its address, in order to limit the repetition of messages.
