Abstract: In order to solve the communication problems in urban cable tunnel construction, this paper first analyzes the development status and technical overview of the current cable tunnel communication modes, and then analyzes the advantages and disadvantages of the main communication modes. According to the communication requirements of tunnel construction, combined with the advantages of LoRa communication technology, this paper puts forward a communication solution for cable tunnel construction based on LoRa technology. The scheme is realized by LM400TU, which can reduce the power consumption during long-distance communication, so as to meet the long-time operation of tunnel construction; it can realize broadcasting function, and the management platform can manage personal terminals; at the same time, the positioning function is added to display the relative position of construction personnel by the upper computer.

隨着城市的迅速发展,电力需求不断增加,为了提高城市的美观和节省地面资源,大量电缆将会埋入地下,因此需要建设大量电缆隧道。电缆隧道一般建设在地下几米至几十米,可长达2~3 km以上。电缆隧道建设避免了室外高压线缆在极端恶劣天气时发生安全事故的风险,从根本上解决电力线路外力破坏的问题[1]。隧道施工过程中,施工人员需要随时观察工作面的山体变化、照明线路的破损状况,发现问题及时汇报,才能迅速撤离施工人员及工作机械,保证施工人员的安全。目前,隧道施工人员之间的通信主要依靠对讲机,但距离较远时只能接力式呼叫,给隧道建设带来不便。虽然移动通信网络在不断完善,室外基站数量不断增加,但是隧道、矿井内存在很多的移动通信盲区[2],且对讲机信号无法穿透路面,地面人员难以做出及时的安全判断。……
