摘要: 無線數(shù)據(jù)傳輸終端又稱為“工業(yè)領(lǐng)域的手機”,其數(shù)據(jù)傳輸原理與人們平常使用的手機是類似的,。目前無線數(shù)據(jù)傳輸終端中常使用2G/4G網(wǎng)絡(luò)傳輸數(shù)據(jù)。2G/4G網(wǎng)絡(luò)存在帶寬小,、時延大以及接入終端量受限等問題,,因此傳統(tǒng)的數(shù)據(jù)傳輸終端不適用車聯(lián)網(wǎng)和大型工控領(lǐng)域。將5G技術(shù)應(yīng)用到DTU(Data Transfer Unit)中,,設(shè)計了一個高可靠性的5G數(shù)據(jù)傳輸終端即5G-DTU,。它的主處理器為Rockchip公司的RK1808芯片,集成了5G通信模組,、WiFi模塊和接口模塊,。因此5G-DTU能為外置設(shè)備提供2.4 G和5 G雙頻段的無線接入以及豐富的外設(shè)接口。最后通過測試證明了5G-DTU的高帶寬,、低延時和高可靠性,。

Abstract: The wireless data transmission terminal is also called "the mobile phone in the industrial field", and its data transmission principle is similar to that of the mobile phones we usually use. The use of 2G/4G networks to transmit data is common in traditional data transmission units. 2G/4G networks have problems such as small bandwidth, large delay, and limited number of access terminals. Therefore, the traditional data transmission unit is not suitable for the Internet of Vehicles and large-scale industrial control fields. This paper innovatively combines 5G technology and DTU(Data Transfer Unit), to design a 5G data transmission terminal with high reliability, namely 5G-DTU. Its main processor is Rockchip′s RK1808 chip, which integrates 5G communication module, WiFi module and interface module. Therefore, 5G-DTU can provide 2.4 G and 5 G dual-band wireless access for external devices, and a wealth of peripheral interfaces. Finally, the test results show that the 5G-DTU has the characteristics of high data band, low time delay and high reliability.

隨著國家全力推進5G網(wǎng)絡(luò)建設(shè),截止到2020年9月,,國內(nèi)已經(jīng)建成了超過48萬個的5G基站,,5G用戶超過6 000萬,5G網(wǎng)絡(luò)終端連接數(shù)量已經(jīng)超過一億[1-2],。隨著5G網(wǎng)絡(luò)的發(fā)展,,5G行業(yè)的應(yīng)用也應(yīng)運而生,5G行業(yè)得到了蓬勃發(fā)展,。
5G已成為引領(lǐng)融合創(chuàng)新,、激發(fā)新型信息消費的新動力,成為促進產(chǎn)業(yè)升級,、驅(qū)動經(jīng)濟持續(xù)增長的新引擎,。5G的三大典型應(yīng)用場景為eMBB(增強型移動寬帶),、mMTC(海量機器通信)和uRLLC(超低時延超高可靠)[3],尤其對于垂直行業(yè)應(yīng)用領(lǐng)域,,比如遠(yuǎn)程醫(yī)療,、遠(yuǎn)程工業(yè)控制、無人駕駛等都對高帶寬和低時延提出了非常高的要求[4],。而傳統(tǒng)數(shù)據(jù)傳輸終端,,多采用2G/4G網(wǎng)絡(luò)進行數(shù)據(jù)傳輸,相較于5G網(wǎng)絡(luò)存在帶寬不夠,、延時高等缺陷,,對遠(yuǎn)程工控、無人駕駛等對實時性,、穩(wěn)定性以及帶寬要求較高的工業(yè)領(lǐng)域并不適用,。
