style="text-indent:25px">在實質上，DTU和數據處理中心樹立的是SOCKET銜接。DTU是SOCKET客戶端，數據處理中心是SOCKET的服務端。SOCKET銜接有TCP協(xié)議和UDP協(xié)議之分，DTU和中心要運用相同的協(xié)議，這個一般都有裝備軟件進行裝備。給DTU裝備好中心的IP地址和端口號后，則把DTU經過串口和用戶的設備相連。DTU和水文、電力、氣候、環(huán)保等用戶設備經過串口連起來放置在現場。 DTU上電后首要注冊到移動的網絡，然后發(fā)送樹立SOCKET的懇求包給移動，移動把這個懇求發(fā)送到因特網。中心的服務端軟件接收到懇求后樹立銜接，并發(fā)送應答信息。 </p><p style="text-indent:25px">因為TCP/UDP通訊銜接現已樹立，就可以進行數據雙向通訊了。關于DTU來說，只需樹立了與數據中心的雙向通訊，完成用戶串口數據與GPRS網絡數據包的轉換就相對簡略了。一旦接收到用戶的串口數據，DTU就當即把串口數據封裝在一個TCP/UDP包里，發(fā)送給數據中心。反之，當DTU收到數據中心發(fā)來的TCP/UDP包時，從中取出數據內容，當即經過串口發(fā)送給用戶設備。經過有線的數據采集中心，一起與許多個GPRS DTU進行雙向通訊。這是目前GPRS DTU運用體系中**為常用的辦法。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="天津GPRS-dtu外殼價格,GPRS-dtu外殼"

DTU，*在前期做了一些簡略測驗就完畢選型作業(yè)，實際上是很不充分的。假如選用了不安穩(wěn)的GPRS DTU并大量運用, 怎么可以在一開端，就能***而快速的測驗GPRS DTU安穩(wěn)性？這現已成為一個重要課題！遺憾的是，大多GPRS DTU廠家都只是宣揚自己產品安穩(wěn)性好，而關于詳細的安穩(wěn)性測驗辦法，則沉默不談！這里，是經過驗證的GPRS DTU安穩(wěn)性測驗流程，可操作的GPRS DTU辨別辦法，這套測驗辦法，可以快速辨別GPRS DTU的主要通訊功能和安穩(wěn)性。天津GPRS-dtu外殼價格</p><p style="text-indent:25px">天津GPRS-dtu外殼價格</p><p
