基于分布式MIMO系统的井下分布式智能小区认知通信方案

Cognitive communication scheme of the mine distributed intelligent cell based on the distributed MIMO system

井下无线通信是矿井安全生产和信息化管理的重要组成部分.针对目前井下无线通信环境恶劣、通信性能不稳定的现状,基于分布式MIMO系统,采用双基站、双系统控制模块结构,利用群切换思想,提出了井下分布式智能小区认知通信方案.移动终端根据自适应原理、采用闭环功率控制,按照小区重组条件自动寻找、选择,及时建立质量更好的智能小区认知通信,使用户始终处于智能小区的中心,明显提高了井下通信的质量和容量,确保了井下生产安全的通信畅通无阻.

The wireless communication in mine is the importance of the mineral well safety production and information-based management to constitute part.Aiming at currently present condition of wireless communication in mine with the bad environment and communication function unsteady,based on the distributed MIMO system,adopting double base stations,double system control mold structure,making use of the tactics of group handover,we put forward the distributed intelligent cell scheme for cognitive communication in mine.According to self adaptive principle,adoption shut a wreath power control and reorganizing conditions,move terminal automatically looks for,chooses and builds up cell of better intelligence of quality＇s cognizing communication that makes the user always be placed in the center of intelligence cell.This proposed system obviously raises the communication＇s quality and capacity in mine,ensures production safety in mine of the communication without obstruction.
