Architecture design of coal mine 5G fusion communication system

Abstract

In view of the problems of system independence, lack of linkage and interworking, and unified scheduling in the communication system of coal mines, the architecture design requirements for building a 5G integrated communication system in coal mines are studied to meet the typical application scenarios of underground linkage scheduling, remote （unmanned） control, and inspection robots; the technical requirements of the system for low delay / high reliability, data safety and large bandwidth in carrying multiple data services such as collection, control and two-way interaction are analyzed; this paper studies the network extension structure, safety operation mechanism, API multi-level architecture, and the design requirements of the dynamic network control strategy of the coal mine 5G integrated communication platform architecture using NGN network architecture, SIP soft switch protocol and open interface technology; this paper discusses the interface types, business requirements, and construction methods of the wireless bearer network based on 5G communication, and analyzes the conclusions of three typical linkage applications. The research results show that the architecture design and linkage application test of the 5G based coal mine integrated communication system are of great significance to solve the problems of interface compatibility, remote control, unified scheduling faced in the construction of intelligent minemultiple systems.
