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

  • 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.
