Aiming at the problem of difficult multi-protocol wireless access caused by the heterogeneous protocols of underground intelligent mine equipment and the harsh communication environments, a VxLAN over 5G multi-protocol transparent access scheme suitable for mine scenarios was proposed based on the special channel constraints and 5G private network transmission technology in underground mines. A unified two-layer virtual tunnel was constructed over the 5G network to directly encapsulate and transmit raw Ethernet frames of mainstream industrial protocols such as EtherCAT and PROFINET, without secondary modification to the protocol stacks of existing mine equipment, which greatly reduces the cost of upgrading and reconstructing underground communication networks. The actual verification was carried out by building a simulated mine underground 5G private network test platform. The results show that the end-to-end average latency of EtherCAT protocol data is 22.508 ms, and the maximum latency is 44.794 ms. The average latency of PROFINET protocol data is 21.007 ms and the maximum latency is 44.477 ms. The latency of both protocol data can stably meet the real-time requirements for scenarios such as condition monitoring of fixed underground mine equipment (latency≤100 ms) and conventional remote control of auxiliary operation robots (latency≤50 ms). However, for strong real-time control scenarios such as mining faces that require millisecond-level synchronization accuracy (latency≤1 ms), the current scheme cannot support it, and needs to be further optimized in combination with 5G URLLC enhancement features. The research results can provide a feasible technical path with low transformation cost and high versatility for the wireless access of multi-protocol heterogeneous equipment in non-coal mines, and provide engineering reference for the refined service bearer of 5G private network in intelligent mines.

针对智能矿山井下设备协议异构、通信环境恶劣导致的多协议无线接入难的问题，本文从矿山井下特殊信道约束与5G专网传输技术基础出发，提出一种适配矿山场景的VxLAN over 5G多协议透明接入方案，在5G网络上构建统一二层虚拟隧道，将EtherCAT、PROFINET等主流工业协议的原始以太网帧直接封装传输，无需对原有矿山设备的协议栈进行二次改造，大幅降低了井下通信网络升级改造的成本。通过搭建模拟矿山井下5G专网试验平台开展实测验证。研究结果表明，EtherCAT协议数据的端到端平均时延22.508 ms，最大时延44.794 ms；PROFINET协议数据平均时延21.007 ms，最大时延44.477 ms，两类协议数据时延均可稳定满足矿山井下固定设备状态监控（时延≤100 ms）、辅助作业机器人的常规远程控制（时延≤50 ms）等场景的实时性要求；但对于采掘工作面等需要毫秒级同步精度的强实时控制场景（时延≤1 ms），当前方案尚无法支持，需结合5G URLLC增强特性进一步优化。研究结果可为非煤矿山井下多协议异构设备的无线接入提供一种低改造成本、高通用性的可行技术路径，为智能矿山5G专网的精细化业务承载提供工程参考。
