\u00bfQu\u00e9 es una DTU?<\/h2>\n<\/div>\n
DTU (Unidad terminal de datos<\/strong><\/a>) es un dispositivo terminal inal\u00e1mbrico utilizado para la transmisi\u00f3n de datos que, como su nombre indica, consigue una transmisi\u00f3n de datos bidireccional transparente.<\/span><\/div>\n
\n

Historia del desarrollo de DTU<\/h2>\n<\/div>\n
\n
    \n
  • En la d\u00e9cada de 1920 se desarroll\u00f3 la primera DTU, y la tecnolog\u00eda de multiplexaci\u00f3n que cumpl\u00eda la definici\u00f3n de DTU se utiliz\u00f3 en las l\u00edneas dedicadas a las noticias<\/li>\n
  • En los a\u00f1os 40, los DTU se utilizaban en las m\u00e1quinas de escribir<\/li>\n
  • En 1958, las DTU se aplicaron a aplicaciones militares y se denominaron DTU inteligentes<\/li>\n
  • En la d\u00e9cada de 1970, tras la aparici\u00f3n de las redes celulares inal\u00e1mbricas, las DTU evolucionaron hacia dispositivos terminales inal\u00e1mbricos, convirti\u00e9ndose en uno de los dispositivos de comunicaci\u00f3n importantes en el IoT<\/li>\n
  • En 1981, las DTU se introdujeron en China<\/li>\n
  • Alrededor de 1990, los fabricantes chinos empezaron a investigar, desarrollar y dise\u00f1ar productos DTU.<\/li>\n
  • Con el continuo desarrollo de las redes 3G, 4G y NB-IoT, empezaron a aparecer DTU 4G y DTU NB-IoT<\/li>\n
  • Hoy en d\u00eda, a medida que maduran tecnolog\u00edas de comunicaci\u00f3n como LoRa, WiFi y Bluetooth, han aparecido posteriormente DTU LoRa, DTU WiFi y otros dispositivos<\/li>\n<\/ul>\n<\/div>\n
    \n

    Principio de funcionamiento de la DTU<\/h2>\n<\/div>\n
    La DTU se conecta a los dispositivos terminales a trav\u00e9s de interfaces y, tras adquirir los datos, los transmite de forma inal\u00e1mbrica a trav\u00e9s de redes portadoras (2G\/3G\/4G\/5G) a los centros de datos o dispositivos designados. Simult\u00e1neamente, los centros de datos tambi\u00e9n pueden enviar datos o comandos en sentido inverso a trav\u00e9s de las redes portadoras a la DTU, que a su vez los reenv\u00eda a los dispositivos terminales a trav\u00e9s de interfaces, logrando as\u00ed aplicaciones como la recopilaci\u00f3n de datos en tiempo real y los servicios de bases de datos.<\/span><\/div>\n
    \n

    Funciones b\u00e1sicas de DTU<\/h2>\n<\/div>\n
    \n
      \n
    1. Comunicaci\u00f3n de datos<\/strong>: Las DTU disponen internamente de pilas de protocolos TCP\/IP integradas, compatibles con la transmisi\u00f3n de datos de doble canal a trav\u00e9s de GPRS\/CDMA y SMS; admiten la comunicaci\u00f3n de datos con m\u00faltiples centros.<\/li>\n<\/ol>\n<\/div>\n
      \n
        \n
      1. Recogida de datos<\/strong>: Recoge datos de dispositivos de puerto serie como instrumentos serie, colectores, PLC, etc.<\/li>\n<\/ol>\n<\/div>\n
        \n
          \n
        1. Apoyo a la permanencia en l\u00ednea<\/strong>: Las DTU incluyen funciones como la marcaci\u00f3n autom\u00e1tica al encenderse, el uso de paquetes heartbeat para garantizar el estado en l\u00ednea permanente, la compatibilidad con la reconexi\u00f3n autom\u00e1tica tras la desconexi\u00f3n, la rellamada autom\u00e1tica, etc., lo que permite que los dispositivos permanezcan en l\u00ednea de forma permanente.<\/li>\n<\/ol>\n<\/div>\n
          \n
            \n
          1. Almacenamiento permanente<\/strong>: Los dispositivos terminales DTU pueden almacenar permanentemente los par\u00e1metros configurados en componentes de almacenamiento (como FLASH, EEPROM). Una vez alimentado, el DTU completar\u00e1 su trabajo autom\u00e1ticamente seg\u00fan los par\u00e1metros configurados<\/li>\n<\/ol>\n<\/div>\n
            \n
              \n
            1. Gesti\u00f3n a distancia<\/strong>: Admite actualizaciones remotas de programas, consultas remotas de par\u00e1metros de configuraci\u00f3n por SMS, reinicios remotos de dispositivos y configuraci\u00f3n remota de par\u00e1metros de dispositivos.<\/li>\n<\/ol>\n<\/div>\n
              \n
                \n
              1. Cifrado de datos<\/strong>: Admite el cifrado de datos, con m\u00e9todos de cifrado como DES, 3DES y AES.<\/li>\n<\/ol>\n<\/div>\n
                \n

                Tipos de productos DTU<\/h2>\n<\/div>\n
                Por m\u00e9todo de comunicaci\u00f3n: Las DTU pueden clasificarse en DTU GPRS, DTU WiFi, DTU CAN y DTU 5G\/4G de red completa.<\/span><\/div>\n
                Por tipo de interfaz: Por lo general, las DTU admiten interfaces RS485, RS232, E\/S, TTL, etc.<\/span><\/div>\n
                Por factor de forma: Las DTUs se pueden clasificar en DTUs de prop\u00f3sito general y DTUs embebidas, con poca diferencia funcional entre ellas, siendo la principal distinci\u00f3n si tienen carcasa o no<\/span><\/div>\n
