DTU上電后，首先讀出內(nèi)部FLASH中保存的作業(yè)參數(shù)(包含GPRS撥號參數(shù)，串口波特率，數(shù)據(jù)中心IP地址等等，事前現(xiàn)已裝備好)。 GPRS DTU登陸GSM網(wǎng)絡，然后進行GPRS PPP撥號。撥號成功后，GPRS DTU將獲得一個由移動隨機分配的內(nèi)部IP地址(一般是10.X.X，北京4G-DTU外殼官網(wǎng).X)。也就是說，GPRS DTU處于移動內(nèi)網(wǎng)中，北京4G-DTU外殼官網(wǎng)，北京4G-DTU外殼官網(wǎng)，并且其內(nèi)網(wǎng)IP地址通常是不固定的，隨著每次撥號而改變。咱們能夠理解為GPRS DTU這時是一個移動內(nèi)部局域網(wǎng)內(nèi)的設備，經(jīng)過移動網(wǎng)關來實現(xiàn)與外部Internet公網(wǎng)的通訊。這與局域網(wǎng)內(nèi)的電腦經(jīng)過網(wǎng)關訪問外部網(wǎng)絡的辦法類似。北京4G-DTU外殼官網(wǎng)</p><div style="width:100%;text-align:

style="text-indent:25px">因而只有DTU是不能完結數(shù)據(jù)的無線傳輸?shù)?，還需求有后臺軟件的配合一起運用。在樹立銜接后，前端的設備和后臺的中心就能夠經(jīng)過DTU進行無線數(shù)據(jù)傳輸了，并且是雙向的傳輸。 DTU現(xiàn)已廣（guang）泛運用于電力、環(huán)保、LED信息發(fā)布、物流、水文、氣候等職業(yè)領域。如上圖所示，雖然運用的職業(yè)不同，但運用的原理是相同的。大都是DTU和職業(yè)設備相連，比方PLC，單片機等主動化產(chǎn)品的銜接，然后和后臺樹立無線的通訊銜接。在互聯(lián)網(wǎng)日益發(fā)展的今（jin）天，DTU的運用也越來越廣（guang）泛。它為各職業(yè)以及各職業(yè)之間的信息、工業(yè)融合供給了協(xié)助。 </p><p style="text-indent:25px">GPRS DTU主動主張與數(shù)據(jù)中心的通訊銜接，并堅持通訊銜接一直存在。由于GPRS DTU處于移動內(nèi)網(wǎng)，并且IP地址不固定。因而，只能由GPRS DTU主動銜接數(shù)據(jù)中心，而不能由數(shù)據(jù)中心主動銜接GPRS DTU。這就要求數(shù)據(jù)中心具有固定的公網(wǎng)IP地址或固定的域名。數(shù)據(jù)中心的公網(wǎng)IP地址或固定的域名作為參數(shù)存儲在GPRS DTU內(nèi)，以便GPRS DTU一旦上電撥號成功，就能夠主動銜接到數(shù)據(jù)中心。詳細地講，GPRS DTU經(jīng)過數(shù)據(jù)中心的IP地址(假如是選用中心域名的話，先經(jīng)過中心域名解析出中心IP地址)以及端口號等參數(shù)，向數(shù)據(jù)中心主張TCP或UDP通訊懇求。在得到中心的響應后，GPRS DTU即認為與中心握手成功，然后就堅持這個通訊銜接一直存在，假如通訊銜接中止，GPRS DTU將當即從頭與中心握手。由于TCP/UDP通訊銜接現(xiàn)已樹立，就能夠進行數(shù)據(jù)雙向通訊了。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="北京4G-DTU外殼官網(wǎng),4G-DTU外殼"
