style="text-indent:25px">關于DTU來說，只需樹立了與數(shù)據(jù)中心的雙向通訊，完結(jié)用戶串口數(shù)據(jù)與GPRS網(wǎng)絡數(shù)據(jù)包的轉(zhuǎn)換就相對簡單了。一旦接收到用戶的串口數(shù)據(jù)，DTU就當即把串口數(shù)據(jù)封裝在一個TCP/UDP包里，發(fā)送給數(shù)據(jù)中心。反之，當DTU收到數(shù)據(jù)中心發(fā)來的TCP/UDP包時，從中取出數(shù)據(jù)內(nèi)容，當即經(jīng)過串口發(fā)送給用戶設備。經(jīng)過有線的數(shù)據(jù)收集中心，一起與許多個GPRS DTU進行雙向通訊。這是現(xiàn)在GPRS DTU運用體系中**為常用的辦法。運用領域 DTU的主要功能是把遠端設備的數(shù)據(jù)經(jīng)過無線的辦法傳送回后臺中心。如右圖所示，要完結(jié)數(shù)據(jù)的傳輸需求樹立一套完好的數(shù)據(jù)傳輸體系。在這個體系中包含:DTU，客戶設備、移動網(wǎng)絡、后臺中心。在前端，DTU和客戶的設備經(jīng)過232或許485接口相連。DTU上電運轉(zhuǎn)后先注冊到移動的GPRS網(wǎng)絡，然后去和設置在DTU中的后臺中心樹立SOCKET銜接。后臺中心作為SOCKET的服務端，DTU是SOCKET銜接的客戶端。</p><p
