Was ist eine DTU?<\/h2>\n<\/div>\n
Die DTU ist eines der h\u00e4ufigsten IoT-Kommunikationsger\u00e4te, denen wir bei unserer t\u00e4glichen Arbeit begegnen. Die meisten Menschen verstehen dieses Ger\u00e4t jedoch nur in seinem Grundkonzept als Daten\u00fcbertragungsinstrument. Was genau ist also ein DTU? Nehmen wir das Beispiel der industriellen DTU der Serie OM302 von Dongyong Technology, um eine einfache Einf\u00fchrung zu geben.<\/span><\/div>\n
\n

Verstehen von Daten\u00fcbertragungseinheiten<\/h2>\n<\/div>\n
DTU steht f\u00fcr Daten\u00fcbertragungseinheit<\/strong><\/a>. Es wird in erster Linie als drahtloses Endger\u00e4t verwendet, das zwischen seriellen Daten und IP-Daten f\u00fcr die \u00dcbertragung \u00fcber drahtlose Netzwerke konvertiert. Einfach ausgedr\u00fcckt, bezieht sich DTU in der Regel auf die GPRS\/CDMA-\u00dcbertragungsendger\u00e4te der unteren Ebene in der drahtlosen Kommunikation. Dar\u00fcber hinaus kann w\u00e4hrend der Kommunikation jedes Modul, das f\u00fcr das Senden von Daten an beiden Enden der \u00dcbertragungsstrecke verantwortlich ist, als DTU bezeichnet werden. W\u00e4hrend dies jedoch eine Art von Modul darstellt, ist das, was wir im t\u00e4glichen Leben am h\u00e4ufigsten antreffen, das eigentliche Ger\u00e4t.<\/span><\/div>\n

Obere vs. untere Maschinen: Ein Schl\u00fcsselkonzept<\/h2>\n<\/div>\n
An dieser Stelle werden Sie sich vielleicht \u00fcber den oben erw\u00e4hnten Begriff der \"unteren Maschine\" wundern. \"Obere Maschine\" und \"untere Maschine\" sind relative Begriffe. In der Ger\u00e4tekommunikation mit einer Master-Slave-Beziehung ist das Ger\u00e4t, das f\u00fcr die \u00dcbermittlung von Informationen zust\u00e4ndig ist, die untere Maschine, w\u00e4hrend das Ger\u00e4t, das die Informationen verarbeitet, die obere Maschine ist. Da DTUs in der Regel f\u00fcr die \u00dcbermittlung von Informationen zust\u00e4ndig sind, fungieren sie als Unterrechner. Die Beziehung zwischen Ober- und Untermaschine ist nicht notwendigerweise eins-zu-eins; es kann F\u00e4lle geben, in denen eine Ober-\/Untermaschine mehreren Maschinen entspricht. Die spezifische Anordnung h\u00e4ngt von den jeweiligen Umst\u00e4nden ab.<\/span><\/div>\n
\n

Multi-Center und Datenverarbeitung<\/h2>\n<\/div>\n
Da wir gerade von der OM302 industrial DTU sprechen, die Multi-Center- und Polling-Concurrent-Strategien bietet, wollen wir kurz erkl\u00e4ren, was ein Rechenzentrum ist. Nachdem die untere Maschine Daten \u00fcbermittelt hat, sammelt, verarbeitet und aggregiert das Datenzentrum diese Daten und verwaltet und steuert die untere Maschine entsprechend. Es geh\u00f6rt zum oberen Maschinensystem und verf\u00fcgt \u00fcber eine komplette Hardware-Ausstattung mit spezifischen Softwarefunktionen.<\/span><\/div>\n

<\/h2>\n

V\u00f6llig transparente \u00dcbertragung erkl\u00e4rt<\/h2>\n<\/div>\n
Das Konzept der \"v\u00f6llig transparenten \u00dcbertragung\" bedeutet, dass die Daten nur \u00fcbertragen werden, ohne sie zu ver\u00e4ndern oder anzupassen. Das Format und der Inhalt der Daten bleiben vor und nach der \u00dcbertragung vollst\u00e4ndig konsistent. Dies ist eine v\u00f6llig transparente \u00dcbertragung, die die Datenintegrit\u00e4t in hohem Ma\u00dfe gew\u00e4hrleistet.<\/span><\/div>\n
\n

Vielf\u00e4ltige Anwendungen<\/h2>\n<\/div>\n
DTUs werden in vielen verschiedenen Branchen eingesetzt, z. B. in der intelligenten Landwirtschaft, in intelligenten St\u00e4dten, in der intelligenten Fertigung, im intelligenten Verkehrswesen, in Handelsunternehmen, im Gesundheitswesen und in vielen anderen Bereichen - in all diesen Bereichen k\u00f6nnen Sie sie finden.<\/span><\/div>\n
\n

Schlussfolgerung<\/h2>\n<\/div>\n
Damit ist unsere kurze Einf\u00fchrung in das DTU-Wissen abgeschlossen. Wenn Sie Fragen haben, k\u00f6nnen Sie gerne einen Kommentar hinterlassen oder uns eine private Nachricht schicken. Bis zum n\u00e4chsten Mal!<\/span><\/div>","protected":false},"excerpt":{"rendered":"
