\"Qu'est-ce<\/p>\n

<\/div>\n
Dans le monde d'aujourd'hui, les dispositifs de communication IoT \u00e9mergent en abondance, avec de nombreux produits de terminaux sans fil qui se distinguent de la foule. Les dispositifs de transmission de donn\u00e9es DTU (Data Terminal Unit) sont reconnus par l'industrie pour leurs puissantes capacit\u00e9s de transmission et leur stabilit\u00e9 sup\u00e9rieure, ce qui en fait l'un des produits les plus couramment appliqu\u00e9s dans les dispositifs de communication IoT. Vous trouverez ci-dessous une explication d\u00e9taill\u00e9e des origines et des sc\u00e9narios d'application des DTU. Jetez-y un coup d'\u0153il !<\/span><\/div>\n

Qu'est-ce qu'un DTU ?<\/h2>\n<\/div>\n
DTU (Unit\u00e9 de terminal de donn\u00e9es<\/strong><\/a>) est un terminal sans fil utilis\u00e9 pour la transmission de donn\u00e9es. Comme son nom l'indique, il permet une transmission transparente et bidirectionnelle des donn\u00e9es.<\/span><\/div>\n
\n

Historique du d\u00e9veloppement de DTU<\/h2>\n<\/div>\n
\n
    \n
  • Dans les ann\u00e9es 1920, le premier DTU a \u00e9t\u00e9 mis au point, la technologie de multiplexage r\u00e9pondant \u00e0 la d\u00e9finition du DTU \u00e9tant utilis\u00e9e dans les nouvelles lignes sp\u00e9cialis\u00e9es.<\/li>\n
  • Dans les ann\u00e9es 1940, les DTU ont \u00e9t\u00e9 utilis\u00e9s dans les machines \u00e0 \u00e9crire<\/li>\n
  • En 1958, les DTU ont \u00e9t\u00e9 appliqu\u00e9s \u00e0 des applications militaires et ont \u00e9t\u00e9 appel\u00e9s DTU intelligents<\/li>\n
  • Dans les ann\u00e9es 1970, apr\u00e8s l'\u00e9mergence des r\u00e9seaux cellulaires sans fil, les DTU ont \u00e9volu\u00e9 vers des terminaux sans fil, devenant ainsi l'un des principaux dispositifs de communication de l'IdO.<\/li>\n
  • En 1981, les DTU ont \u00e9t\u00e9 introduits en Chine<\/li>\n
  • Vers 1990, les fabricants chinois ont commenc\u00e9 \u00e0 rechercher, d\u00e9velopper et concevoir des produits DTU<\/li>\n
  • Avec le d\u00e9veloppement continu des r\u00e9seaux 3G, 4G et NB-IoT, les DTU 4G et les DTU NB-IoT ont commenc\u00e9 \u00e0 appara\u00eetre<\/li>\n
  • Aujourd'hui, alors que les technologies de communication telles que LoRa, WiFi et Bluetooth arrivent \u00e0 maturit\u00e9, des DTU LoRa, des DTU WiFi et d'autres dispositifs sont apparus par la suite<\/li>\n<\/ul>\n<\/div>\n
    \n

    Principe de fonctionnement des DTU<\/h2>\n<\/div>\n
    Le DTU se connecte aux appareils terminaux par le biais d'interfaces et, apr\u00e8s avoir acquis des donn\u00e9es, les transmet sans fil par le biais de r\u00e9seaux d'op\u00e9rateurs (2G\/3G\/4G\/5G) \u00e0 des centres de donn\u00e9es ou \u00e0 des appareils d\u00e9sign\u00e9s. Simultan\u00e9ment, les centres de donn\u00e9es peuvent \u00e9galement envoyer des donn\u00e9es ou des commandes en sens inverse par l'interm\u00e9diaire de r\u00e9seaux porteurs au DTU, qui les transmet ensuite aux appareils terminaux par l'interm\u00e9diaire d'interfaces, ce qui permet de r\u00e9aliser des applications telles que la collecte de donn\u00e9es en temps r\u00e9el et les services de base de donn\u00e9es.<\/span><\/div>\n
    \n

    Fonctions de base de DTU<\/h2>\n<\/div>\n
    \n
      \n
    1. Communication de donn\u00e9es<\/strong>: Les DTU ont des piles de protocoles TCP\/IP int\u00e9gr\u00e9es en interne, prenant en charge la transmission de donn\u00e9es \u00e0 double canal via GPRS\/CDMA et SMS ; elles prennent en charge la communication de donn\u00e9es avec plusieurs centres.<\/li>\n<\/ol>\n<\/div>\n
      \n
        \n
      1. Collecte de donn\u00e9es<\/strong>: Collecte des donn\u00e9es \u00e0 partir de dispositifs \u00e0 port s\u00e9rie tels que des instruments s\u00e9rie, des collecteurs, des automates, etc.<\/li>\n<\/ol>\n<\/div>\n
        \n
          \n
        1. Soutien au statut permanent en ligne<\/strong>: Les DTU comprennent des fonctions telles que la num\u00e9rotation automatique lors de la mise sous tension, l'utilisation de paquets Heartbeat pour garantir un statut en ligne permanent, la compatibilit\u00e9 avec la reconnexion automatique apr\u00e8s d\u00e9connexion, la recomposition automatique, etc. qui permettent aux appareils de rester en ligne de mani\u00e8re permanente<\/li>\n<\/ol>\n<\/div>\n
          \n
            \n
          1. Fournir un stockage permanent<\/strong>: Les terminaux DTU peuvent stocker en permanence les param\u00e8tres configur\u00e9s dans des composants de stockage (tels que FLASH, EEPROM). Une fois aliment\u00e9, le DTU effectuera son travail automatiquement en fonction des param\u00e8tres d\u00e9finis.<\/li>\n<\/ol>\n<\/div>\n
            \n
              \n
            1. Gestion \u00e0 distance<\/strong>: Prise en charge des mises \u00e0 jour de programmes \u00e0 distance, des requ\u00eates de param\u00e8tres de configuration SMS \u00e0 distance, des red\u00e9marrages d'appareils \u00e0 distance, de la configuration de param\u00e8tres d'appareils \u00e0 distance.<\/li>\n<\/ol>\n<\/div>\n
              \n
                \n
              1. Cryptage des donn\u00e9es<\/strong>: Prise en charge du cryptage des donn\u00e9es, avec des m\u00e9thodes de cryptage telles que DES, 3DES, AES<\/li>\n<\/ol>\n<\/div>\n
                \n

                Types de produits DTU<\/h2>\n<\/div>\n
                Selon la m\u00e9thode de communication : Les DTU peuvent \u00eatre class\u00e9es en DTU GPRS, DTU WiFi, DTU CAN et DTU 5G\/4G \u00e0 r\u00e9seau complet.<\/span><\/div>\n
                Par type d'interface : Les DTU prennent g\u00e9n\u00e9ralement en charge les interfaces RS485, RS232, E\/S, TTL et autres.<\/span><\/div>\n
                Par facteur de forme : Les DTU peuvent \u00eatre class\u00e9s en DTU \u00e0 usage g\u00e9n\u00e9ral et DTU int\u00e9gr\u00e9s, avec peu de diff\u00e9rences fonctionnelles entre eux, la principale distinction \u00e9tant la pr\u00e9sence ou non d'un bo\u00eetier.<\/span><\/div>\n
