Abstract
Aiming at the existing problems of signal attenuation,transmission time delay,unbalanced data resource scheduling and so on in the process of unmanned coal mining in Baode Coal Mine,an optimization scheme based on 5G NRSA architecture,MEC edge computing and network slicing technology is proposed.By deploying mine used flameproof and intrinsically safe base station(BBU),HUB convergence equipment and MEC server,the data transmission and processing flow in the downhole complex environment are optimized.Aiming at device management,energy consumption scheduling and intelligent decision-making system,targeted measures are proposed by combining AI and big data analysis technology.The experimental results show that under the 3500 MHz frequency band,the transmission rate reaches 25 Gbit/s,the time delay is controlled within 20 ms,the system stability and intelligentization level are significantly improved,and the operation efficiency of mine unmanned is greatly improved,achieving the operation goal of green,energy-saving,and efficient.关键词
