摘要
5G技术的应用推动了矿山智能化快速发展,井工矿工作环境恶劣,无线传播环境复杂,5G无线覆盖难度较大。重点介绍了井工矿5G专网的架构以及无线网络覆盖方案。井工煤矿对无线设备的射频功率有限制,只能采用皮基站的方案进行覆盖,且井下设备需要进行防爆改造。非煤矿井没有射频功率限制,可以根据现场环境采用皮基站、微基站、泄露电缆或DAS系统的覆盖方案。
The application of 5G technology has promoted the rapid development of mine intelligence.The working environment of mine is harsh,the wireless communication environment is complex,and 5G wireless coverage is difficult.It mainly introduces the architecture of 5G private network and the wireless network coverage scheme.The radio frequency power of wireless equipment is limited in underground coal mine,so it can only be covered by the Pico station scheme,and the underground equipment needs explosion-proof transformation.There is no RF power limitation for non coal mines,and the coverage scheme of Pico station,Micro station,leaky cable or DAS system can be adopted according to the site environment.
