摘要: 5G网络的大宽带、少延时、广接入奠定了各行各业必要的网络基础设施,并推动着城市轨道交通建设的不断丰富。为了有效解决在地铁施工建设发生意外时,救援人员无法精确获取施工现场人员的实时位置,无法快速到达事故地点实施营救等问题,基于“5G+泛无线”融合技术方案,逐一分析Wi-Fi、蓝牙、 RFID、超声波、UWB等定位技术优缺点,在充分结合城市轨道交通地下应用场景后,最终提出采用“5G+蓝牙”融合定位技术方案,通过构建5G网络与蓝牙定位两张网络,进行定位数据回传、完成信息上报,使5G微基站成为移动蜂窝网络和蓝牙定位网络的信息汇聚中心,从而达到准确定位的效果。

Abstract: The large broadband, short delay and wide access of 5G network have laid the foundation of the necessary network infrastructure for all kinds of professions and promoted the continuous enrichment of urban rail transit construction. However, when accidents happen during metro construction, rescue workers cannot obtain the accurate real-time position of the construction site personnel and cannot quickly arrive at the accident site for rescue. In order to effectively solve these problems, this paper, based on the plan of "5G+ ubiquitous wireless" fusion technology, analyzes the advantages and disadvantages of WiFi, Bluetooth, RFID, ultrasonic waves, UWB, and other positioning technologies one by one. After fully considering the underground application scenarios of urban rail transit, a solution of "5G+ Bluetooth" fusion positioning technology is finally proposed. By establishing two networks, namely a 5G network and a Bluetooth positioning network, positioning data is returned and information is reported. This allows 5G micro base stations to become the information hubs of the mobile cellular network and the Bluetooth positioning network, enabling accurate positioning.

Key words: 5G, ubiquitous wireless , metro construction, positioning technology
