煤矿5G通信系统安全技术要求和检验方法

Safety technical requirements and inspection methods of coal mine 5G communication system

用于煤矿井下的5G通信系统必须取得安全标志证书。为更好地推动煤矿智能化建设和煤矿5G技术发展,让送审企业提前熟悉煤矿5G通信系统技术要求和检验要求,缩短送审周期,研究了煤矿5G通信系统安全技术要求和检验方法。从基本要求、组网要求、5G通信技术要求、防爆安全要求、抗干扰要求等方面论述了煤矿5G通信系统安全技术要求,并针对需重点关注的问题提出相关建议。针对煤矿5G通信系统,重点关注系统组网方式判别、核心网检验、抗干扰性能检验;针对5G基站和终端,重点关注5G技术指标的检验和防爆安全要求。对煤矿5G通信系统管理问题、5G基站多天线功率叠加后阈功率的计算问题、抗干扰技术难点、传输速率和时延的技术要求和检验方法、天线一体化基站的检验、矿用5G上下行带宽存在的问题进行了探讨。

The 5G communication system used in coal mines must obtain a safety mark certificate.In order to better promote the intelligent construction of coal mines and the development of 5G technology in coal mines,help the companies to understand the technical requirements of coal mine 5G communication system and inspection requirements in advance,shorten the review period,this paper studies the safety technical requirements and inspection methods of coal mine 5G communication system.The safety technical requirements of coal mine 5G communication systems are discussed in terms of basic requirements,networking requirements,5G communication technology requirements,explosion-proof safety requirements and anti-interference requirements.Moreover,relevant suggestions are made for the issues that need to be focused on.In terms of the coal mine 5G communication system,this paper focuses on the system networking mode discrimination,core network inspection and anti-interference performance inspection.In terms of 5G base stations and terminals,this paper focuses on the inspection of 5G technical indicators and explosion-proof safety requirements.The issues such as coal mine 5G communication system management issues,5G base station multi-antenna power superposition threshold power calculation issues,anti-interference technical difficulties,the technical requirements and inspection methods of transmission rate and delay,the inspection of antenna-integrated base stations,and the problems of 5G upstream and downstream bandwidth in mines are also discussed in this paper.
